The invention provides a laser hair growth instrument.

In the embodiment of the present invention, as shown in fig. 1, the laserhair growth instrument 10 includes ahousing 100, acircuit board 200, alaser light source 300, and afunctional film 400.

Thecircuit board 200 is provided on thehousing 100.

Thelaser source 300 is disposed on thecircuit board 200, and thelight emitting surface 302 of thelaser source 300 is located on a side of thecircuit board 200 away from thehousing 100. The number of thelaser light sources 300 is plural, and the plural laserlight sources 300 are arranged at intervals. Thelaser light source 300 emits light spots that stimulate the scalp, promote hair regrowth, and prevent hair loss.

In the present embodiment, thelaser light source 300 is connected to the power supply system through thecircuit board 200. It is understood that in other embodiments, thelaser light source 300 may be connected to the power supply system through a conductive wire, and in this case, thecircuit board 200 may be omitted and thelaser light source 300 may be disposed on thehousing 100.

Thefunctional film 400 covers the plurality of laserlight sources 300. Thus, thefunctional film 400 can effectively protect thelaser light source 300 and can also protect electronic components on thecircuit board 200.

In this embodiment, thefunctional film 400 includes abase region 402 and alight source region 404 integrally formed with thebase region 402. The number of thelight source regions 404 is the same as that of thelaser light sources 300, and the light source regions are arranged in a one-to-one correspondence. Thelight source region 404 includes aspot enlarging portion 410, and thespot enlarging portion 410 is used to enlarge the spot emitted from thelaser light source 300.

Thespot enlargement part 410 may enlarge the spots emitted from thelaser light sources 300, so as to facilitate the irradiation of all the scalps, and further facilitate the improvement of the treatment effect, so that the laserhair growth instrument 10 has a better treatment effect, and the irradiation of the scalps of the same area may be realized by using a relatively small number of thelaser light sources 300. The cost of the laserhair growth instrument 10 can be reduced by using a relatively small number of laserlight sources 300.

Thelight source area 404 and thebase area 402 are integrally formed (that is, the lightspot amplifying part 410 and thebase area 402 are integrally formed), and compared with the assembly arrangement of the lightspot amplifying part 410 and thebase area 402, the step of assembling the lightspot amplifying part 410 and thebase area 402 can be omitted, so that the assembly time is saved, the assembly cost of the laserhair growth instrument 10 can be reduced, the production efficiency of producing the laserhair growth instrument 10 can be improved, the more the number of thelaser light sources 300 is, the more the assembly cost is reduced, and the more the production efficiency is improved. In this case, thefunctional film 400 has at least two functions of protecting thelaser light source 300 and amplifying a spot emitted from thelaser light source 300.

Specifically, in the present embodiment, thelight source area 404 and thebase area 402 are made of the same material, and are made of plastic, and thelight source area 404 and thebase area 402 are integrally formed by injection molding.

In some embodiments, as shown in fig. 1-6, thespot enlarging portion 410 is a lens. Specifically, as shown in fig. 1, the lightspot enlarging portion 410 is located on both sides in the light outgoing direction, and is a concave surface that is recessed. As shown in fig. 2, thespot enlargement portion 410 is located on two sides in the light outgoing direction, a side close to thecircuit board 200 is a flat surface, and a side far from thecircuit board 200 is a recessed concave surface. As shown in fig. 3, thespot enlargement portion 410 is located on two sides in the light outgoing direction, a side close to thecircuit board 200 is a concave surface that is recessed, and a side far from thecircuit board 200 is a flat surface. As shown in fig. 4, thespot enlargement portion 410 is located on both sides in the light outgoing direction, and is convex. As shown in fig. 5, thespot enlargement portion 410 is located on two sides in the light outgoing direction, a side close to thecircuit board 200 is a plane, and a side far from thecircuit board 200 is a convex surface. As shown in fig. 6, thespot enlargement portion 410 is located on two sides in the light outgoing direction, the side close to thecircuit board 200 is a convex surface, and the side far from thecircuit board 200 is a plane.

In the present embodiment, thespot enlargement portion 410 is spaced from thelight emitting surface 302 of thelaser light source 300 in the light emitting direction. In this manner, thespot amplifying section 410 is more convenient to amplify the spot emitted from thelaser light source 300, and is also convenient to dissipate the heat generated by the operation of thelaser light source 300.

In this embodiment, as shown in fig. 1, an avoiding hole is formed in a region of thebase region 402 corresponding to thelaser light source 300, and thelaser light source 300 is located in the avoiding hole. Thelight source region 404 further includes a surroundingportion 420, the surroundingportion 420 is disposed around thelaser light source 300, and one end of the surroundingportion 420 close to thecircuit board 200 is connected to the periphery of the avoiding hole. The end of the surroundingportion 420 away from thecircuit board 200 may be used to dispose thespot enlargement portion 410, so as to very conveniently realize the separation of thespot enlargement portion 410 and thelight emitting surface 302 of thelaser light source 300 in the light emitting direction.

In some embodiments, as shown in fig. 1, an end of the surroundingportion 420 away from thecircuit board 200 is an open end, and a periphery of thespot enlargement portion 410 is connected to a periphery of the open end and closes the open end. In some embodiments, as shown in fig. 4, an end of the surroundingportion 420 away from thecircuit board 200 is a closed end, and thespot enlargement portion 410 is located outside the surroundingportion 420 and on the closed end.

The surroundingportion 420 may surround thelaser light source 300. In some embodiments, as shown in FIG. 1, thesurround 420 has a hemispherical shape. In some embodiments, as shown in fig. 7, thesurround 420 is square.

In the present embodiment, as shown in fig. 1, thelaser generator 10 further includes apositioning column 500, and an end surface of thepositioning column 500 away from thecircuit board 200 is located outside a side of thespot enlargement portion 410 away from thecircuit board 200. When the laserhair growth instrument 10 is used, one end of thepositioning column 500, which is far away from thecircuit board 200, is used to abut against the scalp, so that when the laserhair growth instrument 10 is used, the distance between the light-emitting surface 302 (the light spot enlargement portion 410) of thelaser light source 300 and the scalp can be limited by thepositioning column 500, and the distance between the light-emitting surface 302 (the light spot enlargement portion 410) of thelaser light source 300 and the scalp is prevented from being too close or too far. The distance between the light-emitting surface 302 (the spot enlargement portion 410) of thelaser light source 300 and the scalp is too close to be beneficial to forming a large spot, and the distance between the light-emitting surface 302 (the spot enlargement portion 410) of thelaser light source 300 and the scalp is too far to cause the power loss of the spot to be too large to reach the required power density.

In the present embodiment, a distance between thelight emitting surface 302 of thelaser light source 300 and one end of thepositioning column 500 far away from thecircuit board 200 is less than or equal to 2cm (centimeter). Specifically, in the present embodiment, a distance between thelight emitting surface 302 of thelaser light source 300 and one end of thepositioning column 500 away from thecircuit board 200 is 0.5-2cm (cm). More specifically, in the present embodiment, a distance between thelight emitting surface 302 of thelaser light source 300 and one end of thepositioning column 500 away from thecircuit board 200 is 1-2cm (centimeters).

In the present embodiment, the positioningpillars 500 are multiple, and thepositioning pillars 500 are arranged at intervals. More specifically, in the present embodiment, thepositioning column 500 is elongated. The positioning posts 500 are arranged in a comb shape.

In some embodiments, positioningpost 500 is independent fromlight source area 404. Thepositioning column 500 is disposed through thebase region 402 and is fixedly connected to thecircuit board 200. The number of thepositioning pillars 500 may be greater than, equal to, or less than the number of thelaser light sources 300.

In some embodiments, as shown in fig. 1, thepositioning column 500 is disposed on thebase region 402, and thepositioning column 500 is independent from thelight source region 404, that is, the orthographic projections of thepositioning column 500 and thelight source region 404 on the same plane are independent from each other and do not overlap. The number of thepositioning pillars 500 may be greater than, equal to, or less than the number of thelaser light sources 300.

In the present embodiment, the positioning posts 500 are integrally formed with thebase region 402. Forreference column 500 andbase district 402 assembly setting,reference column 500 andbase district 402 integrated into one piece can omit the step of assemblingreference column 500 andbase district 402, practice thrift the assemble duration, not only can reduce the assembly cost thatappearance 10 was grown to laser, can also improve the production efficiency thatappearance 10 was grown to production laser, andreference column 500's figure is more moreover, and assembly cost's reduction is more obvious, and production efficiency's improvement is more obvious. In this case, thefunctional film 400 has at least three functions of protecting thelaser light source 300, amplifying thelaser light source 300, and positioning the scalp distance.

It should be noted that the positioning posts 500 are integrally formed with thebase region 402, and thespot enlarging portion 410 is integrally formed with thebase region 402, that is, thespot enlarging portion 410, the positioning posts 500 and thebase region 402 are integrally formed. Specifically, in the present embodiment, the material of thespot amplification portion 410, thepositioning column 500 and thesubstrate area 402 are the same, and are all plastic materials, and may be integrally formed by injection molding. More specifically, in the present embodiment, the material of thespot enlargement portion 410, thepositioning column 500, and thesubstrate area 402 is Polyvinyl chloride (PVC), and the light transmittance of thespot enlargement portion 410, thepositioning column 500, and thesubstrate area 402 is greater than 90%.

In some embodiments, as shown in fig. 5, the positioningpillars 500 are disposed on thebase region 402, and the number of thepositioning pillars 500 is the same as that of thelaser light sources 300, and the positioning pillars are disposed in a one-to-one correspondence. That is, thepositioning column 500 is a part of thelight source area 404, and thelight source area 404 includes thespot enlarging portion 410 and thepositioning column 500. Thespot enlargement unit 410 is disposed on thepositioning post 500. Note that, whenspot enlarging portion 410 is formed integrally withbase region 402, "spot enlarging portion 410 is provided onpositioning column 500" means that "spot enlarging portion 410,positioning column 500, andbase region 402 are formed integrally".

In the present embodiment, as shown in fig. 8 and 9, the positioningpillars 500 surround thelaser light sources 300, and at least a portion of thelaser light sources 300 is received in thecorresponding positioning pillars 500, at this time, a portion for receiving thelaser light sources 300 is considered as a surroundingportion 420, and thepositioning pillars 500 are captured on the surroundingportion 420. In some embodiments, as shown in fig. 8, thepositioning pillar 500 is a hollow pillar with two open ends, and thelaser source 300 and thespot enlargement portion 410 are both located in thepositioning pillar 500. In this case, it can be considered that thepositioning column 500 includes the surroundingportion 420, and thepositioning column 500 has the function of the surroundingportion 420. In some embodiments, as shown in fig. 9, thepositioning pillar 500 is a solid pillar, and one end of thepositioning pillar 500 near thecircuit board 200 is recessed to form a surroundingportion 420. At least one of the end surface of thepositioning column 500 away from thecircuit board 200 and the end surface of the surroundingportion 420 away from thecircuit board 200 is an inward concave arc surface. Thespot enlargement portion 410 includes one or two arcs.

In other embodiments, thepositioning pillar 500 may not surround thelaser light source 300, but is spaced from thelaser light source 300 in the extending direction of thepositioning pillar 500, and at this time, thelaser light source 300 is not located in thepositioning pillar 500.

Thepositioning column 500 not only can limit the distance between the light emitting surface 302 (the light spot enlargement portion 410) of thelaser light source 300 and the scalp, and prevent the light spot enlargement portion 410 (the laser light source 300) from being too close to or too far from the scalp, but also can move the hair, and reduce the area of the scalp shielded by the hair, so that more scalp is irradiated by the laser, and thelaser hair generator 10 has a better effect.

Particularly, when thepositioning column 500 is tapered in the extending direction away from thecircuit board 200, that is, thepositioning column 500 is a tapered structure with a larger end and a smaller end, and the smaller end is used for abutting against the scalp, compared to the structure with the same two ends, thepositioning column 500 with the tapered structure is more convenient for pulling the hair, and reduces the area of the scalp shielded by the hair.

Moreover, when the positioning posts 500 are disposed on thebase region 402 and the number of the positioning posts 500 is the same as that of thelaser light sources 300 and the positioning posts 500 are disposed in a one-to-one correspondence manner, that is, in the embodiment shown in fig. 8 and 9, the positioning posts 500 are used for guiding light and guiding out laser light emitted by thelaser light sources 300, so that the scalp colliding with the positioning posts 500 can be irradiated by the laser light, and the scalp colliding with the positioning posts 500 can be prevented from being irradiated by the laser light. In this way, thepositioning column 500 not only can limit the distance between thespot enlargement portion 410 and the scalp, but also can ensure a large irradiation area of the scalp.

Especially, whenreference column 500 is the convergent structure, the conduction laser of being more convenient for, wherein, part laser just contacts with the scalp after can passingwhole reference column 500, and part laser passespart reference column 500 after, can followreference column 500's side outgoing, then need not pass through remainingpart reference column 500 and directly pass to the scalp to can reduce laser loss, the conduction laser of being more convenient for.

Specifically, in the present embodiment, the power of thelaser light source 300 is 1-5mW (milliwatt). The distance between thespot enlargement portion 410 and thelight exit surface 302 of thelaser light source 300 is less than 0.8 cm. Thespot amplifying section 410 may amplify the spot of thelaser light source 300 by 2 to 6 times. The distance between the light-emittingsurface 302 of thelaser light source 300 and one end of thepositioning column 500 far away from thecircuit board 200 is less than or equal to 2cm (centimeter). The power density of the light spot irradiated on the scalp is 3-15mW/cm²。

When the laserhair growth instrument 10 is manufactured, the laserhair growth instruments 10 of the small size, the medium size and the large size can be manufactured according to the size of the head shape of the crowd, but even if the division is made, the sizes of the head shapes of two different people located at the same level (for example, the head shapes of two different people are both medium-sized, and the laserhair growth instrument 10 of the medium size is applied) are different, and the head shapes of the different people are different. In this way, after the user wears the laserhair growth device 10, there is thepositioning column 500 that cannot collide with the scalp, that is, there is thepositioning column 500 spaced from the scalp. This results in the actual distance between thespot enlargement portion 410 and the scalp being greater than the preset distance between thespot enlargement portion 410 and the scalp. When the actual distance is greater than the preset distance, the actual spot area irradiated to the scalp is greater than the preset spot area, and the actual spot power density is smaller than the preset spot power density.

To ensure that the actual spot area of the laserhair growth instrument 10 is substantially the same as the pre-set spot area. In this embodiment, as shown in fig. 10, the laserhair growth instrument 10 further includes a drivingmember 600, the drivingmember 600 is disposed on thecircuit board 200, and the drivingmember 600 is used for driving thefunctional film 400, so that thespot enlargement portion 410 moves close to or away from thelaser light source 300, thereby adjusting the distance between thespot enlargement portion 410 and the light emitting surface 312 of thelaser light source 300, and further adjusting the spot area irradiated to the scalp, so that the actual spot area irradiated to the scalp is substantially the same as the preset spot area.

For example, when the laserhair growth instrument 10 is worn on the head, the distance between thespot enlargement portion 410 and thelaser light source 300 is an initial distance, and if thepositioning column 500 is in contact with the scalp, it is considered that the actual spot area irradiated to the scalp is substantially the same as the preset spot area; if thepositioning column 500 is spaced from the scalp, it is determined that the actual spot area irradiated to the scalp is larger than the preset spot area, and at this time, the drivingmember 600 drives thefunctional film 400 to move thespot enlarging portion 410 away from thelaser light source 300, so that the distance between thespot enlarging portion 410 and thelaser light source 300 is increased, the actual spot area irradiated to the scalp is reduced, and the actual spot area irradiated to the scalp is substantially the same as the preset spot area.

When the laserhair growth instrument 10 is worn on the head and the distance between thespot enlargement portion 410 and thelaser light source 300 is not the initial distance, the drivingmember 600 drives thefunctional film 400 to move thespot enlargement portion 410 away from or close to thelaser light source 300, so that the distance between thespot enlargement portion 410 and thelaser light source 300 is increased or decreased, and the actual spot area irradiated to the scalp is substantially the same as the preset spot area.

It should be noted that, in this embodiment, the actual spot area irradiated to the scalp is substantially the same as the preset spot area, which means that the actual spot area is 80% -120% of the preset spot area. It is understood that, in other embodiments, the actual spot area irradiated to the scalp may be substantially the same as the preset spot area, which may also mean that the actual spot area is 90% to 110% of the preset spot area.

To ensure that the actual spot power density is substantially the same as the preset spot power density, in this embodiment, the emission power of thelaser light source 300 is adjustable. When thefunctional film 400 is driven by the drivingmember 600, thespot enlarging portion 410 is close to or away from thelaser light source 300 to move, so that the transmitting power of thelaser light source 300 is increased after the actual spot area irradiated to the scalp is approximately the same as the preset spot area, and the actual spot power density is increased and is approximately the same as the preset spot power density.

That is, in the present embodiment, the distance between thespot enlarging unit 410 and thelaser light source 300 may be adjusted, and the emission power of thelaser light source 300 may be adjusted, so that the actual spot area irradiated to the scalp is substantially the same as the preset spot area, and the actual spot power density is substantially the same as the preset spot power density.

It should be noted that, in this embodiment, the actual spot power density is substantially the same as the preset spot power density, which means that the actual spot power density is 80% -120% of the preset spot power density. It is understood that, in other embodiments, the actual spot power density is substantially the same as the preset spot power density, which may also mean that the actual spot power density is 90% -110% of the preset spot power density.

Specifically, in the present embodiment, the laserhair growth instrument 10 further includes a distance sensor (not shown). The distance sensor is disposed on thecircuit board 200, and is used for obtaining an actual distance between thelight emitting surface 302 of thelaser light source 300 and the scalp. The drivingmember 600 is electrically connected to the distance sensor, and the drivingmember 600 can drive thefunctional film 400 according to the actual distance, so that the actual spot area irradiated to the scalp is substantially the same as the preset spot area.

In practical applications, when the laserhair growth instrument 10 is worn on the head, the actual distance between the light-emittingsurface 302 of thelaser light source 300 and the scalp is determined, and when the actual distance between the light-emittingsurface 302 of thelaser light source 300 and the scalp is obtained by the distance sensor (for example, the actual distance is 5mm, which is greater than the preset distance 4mm between the light-emittingsurface 302 of thelaser light source 300 and the scalp, and at this time, thepositioning column 500 is spaced from the scalp by 1mm), the drivingmember 600 can drive thefunctional film 400 according to the actual distance, so that the distance between thespot enlarging portion 410 and thelaser light source 300 is increased (for example, increased by 0.1mm), and at this time, the actual spot power density is substantially the same as the preset spot power density.

Specifically, in this embodiment, the laserhair growth instrument 10 further includes a main control board, and the distance sensor and the drivingmember 600 are electrically connected to the main control board. The memory of the main control board stores a correspondence table between "the actual distance between thelaser light source 300 and the scalp" and "the distance between thespot enlargement unit 410 and thelaser light source 300" in advance, and the correspondence table is obtained by an experimental test. Thus, when the distance sensor obtains the actual distance between thelaser light source 300 and the scalp, the increase in the distance between thespot enlargement unit 410 and thelaser light source 300 can be obtained by looking up the table.

Specifically, in the present embodiment, the memory of the main control board also prestores a correspondence table between "the increase in the distance between thespot enlargement portion 410 and thelaser light source 300" and "the emission power of thelaser light source 300", which is obtained through experimental tests. Thus, when "the distance between thespot enlargement unit 410 and thelaser light source 300 is increased" is obtained, the "emission power of thelaser light source 300" can be obtained by looking up the table.

It should be noted that in the present embodiment, the drivingmember 600 is activated only when the absolute value of the difference between the actual distance and the preset distance is greater than 10% of the preset distance. That is, when the absolute value of the difference between the actual distance and the preset distance is less than or equal to 10% of the preset distance, the drivingmember 600 is not activated. For example, when the actual distance is 5mm and the preset distance is 4mm, the absolute value of the difference between the actual distance and the preset distance is 25% of the preset distance and is greater than 10%, and the drivingmember 600 is activated; when the actual distance is 4.4mm and the preset distance is 4mm, the absolute value of the difference between the actual distance and the preset distance is 10% of the preset distance and is not greater than 10%, and the drivingmember 600 is not started; when the actual distance is 3.5mm and the preset distance is 4mm, the absolute value of the difference between the actual distance and the preset distance is 12.5% of the preset distance and is greater than 10%, and the drivingmember 600 is started. It will be appreciated that in other embodiments, thedrive member 600 is only activated when the absolute value of the difference between the actual distance and the preset distance is greater than 5% of the preset distance.

It should be noted that, in this embodiment, when the actual spot power density is 80% -120% of the preset spot power density, the emission power of thelaser light source 300 is not adjusted. When the absolute value of the difference between the actual spot power density and the preset spot power density is greater than 20% of the preset spot power density, the emission power of thelaser light source 300 is increased. It is understood that in other embodiments, the emission power of thelaser light source 300 is increased when the absolute value of the difference between the actual spot power density and the preset spot power density is greater than 10% of the preset spot power density.

In the above embodiments, the difference between the "actual distance between thelight emitting surface 302 of thelaser light source 300 and the scalp" (for example, the actual distance is 5mm, which is greater than the preset distance 4mm between thelight emitting surface 302 of thelaser light source 300 and the scalp, and at this time, the distance between thepositioning post 500 and the scalp is 1mm) "and the" distance between thespot enlargement portion 410 and thelaser light source 300 is increased (for example, increased by 0.1mm) "is very large, and at this time, thepositioning post 500 and the scalp are still spaced. That is, the adjustment in the above embodiment is fine adjustment, and is very easy to implement.

In the present embodiment, thefunctional film 400 and thehousing 100 form a closed protection cavity, so as to limit thecircuit board 200 within the protection cavity. Thus, thecircuit board 200 can be well protected against falling, water and dust.

Specifically, in the present embodiment, thecircuit board 200 is movably disposed in the protective cavity formed by thefunctional film 400 and thehousing 100. Thus, it is more convenient to assemble thehousing 100, thecircuit board 200 and thefunctional film 400.

The laserhair growth instrument 10 further comprises an elastic connector, which connects thecircuit board 200 and thebase region 402 of thefunctional film 400. The elastic connection button can fix the positions of thecircuit board 200 and thefunctional film 400, thereby ensuring that eachlight source region 404 and thelaser light source 300 are in one-to-one correspondence, and ensuring the initial distance between thespot enlargement portion 410 and thelaser light source 300.

In this embodiment, under the action of the drivingmember 600, thefunctional film 400 deforms to drive thespot enlargement portion 410 to be away from thelaser light source 300, and after the action of the drivingmember 600 is cancelled, thefunctional film 400 returns to the original state. I.e., thefunctional film 400 has a certain elasticity. In this manner, it is very convenient to realize fine adjustment between thelaser light source 300 and thespot amplifying section 410.

In the present embodiment, the drivingmember 600 is located between thecircuit board 200 and thebase region 402. Thus, thefunctional film 400 can shield and protect the drivingmember 600. More specifically, in the present embodiment, the drivingelement 600 is disposed corresponding to thepositioning column 500, so that it is more convenient to make thepositioning column 500 abut against the scalp. More specifically, in the present embodiment, the drivingmember 600 is a micro motor.

In other embodiments, the drivingmember 600 can also greatly adjust the distance between thespot enlargement portion 410 and thelaser source 300, so that thepositioning column 500 abuts against the scalp. So, be more convenient forreference column 500 to stir the hair, reduce the area of the scalp that is shielded by the hair to make more scalps by laser irradiation, and then make laserhair growth appearance 10 have better effect. In practical applications, after wearing the laserhair growth instrument 10, when a user feels the pressing of thepositioning column 500, it indicates that thepositioning column 500 is abutted against the scalp. When the user cannot feel the pressing of thepositioning column 500, it indicates that thepositioning column 500 does not abut against the scalp, and at this time, the drivingmember 600 may be turned on, so that the drivingmember 600 drives thefunctional film 400 to approach the scalp, and thepositioning column 500 abuts against the scalp. In this case, the distance sensor may be omitted.

The embodiment also provides a calibration method of the laser hair growth instrument, which comprises the following steps:

step S10a, the laser hair generator is worn on the head.

Step S10b, obtain the actual distance between the light emitting surface of the laser light source and the scalp.

Step S10c, when the actual distance between the light-emitting surface of the laser light source and the scalp is greater than the preset distance between the light-emitting surface of the laser light source and the scalp, adjusting the distance between the spot enlargement portion and the light-emitting surface of the laser light source so that the actual spot area irradiated to the scalp is 80% -120% of the preset spot area.

Step S10d, increasing the emission power of the laser source to make the actual spot power density 80% -120% of the preset spot power density.

In the present embodiment, the emission power of thelaser light source 300 is adjustable. Therefore, the emitting power with proper size can be selected according to actual requirements, and the laserhair growth instrument 10 has a better treatment effect.

In this embodiment, the laserhair growth instrument 10 further includes a laser dopplerblood flow sensor 700, and the laser dopplerblood flow sensor 700 is disposed on thecircuit board 200 and is used for detecting the blood flow velocity of the scalp tissue. Specifically, as shown in fig. 10, the laser dopplerblood flow sensor 700 is located between thecircuit board 200 and thebase region 402.

The laser emitted by the laserhair growth device 10 can promote blood circulation, i.e. accelerate the flow rate of blood. The laser dopplerblood flow sensor 700 can detect the flow velocity of blood, and its specific working principle is as follows: the laser dopplerblood flow sensor 700 emits a laser beam that is scattered by the scalp tissue (the tissue under investigation) and then a portion of the laser is absorbed by the scalp tissue. The laser wavelength that hits the blood cells is changed (i.e., doppler shifted) while the laser wavelength that hits the stationary tissue is unchanged. The intensity and frequency distribution of these wavelength changes is directly related to the number of blood cells in the scalp tissue and the speed of movement. The laser dopplerblood flow sensor 700 obtains information such as the number of blood cells and the moving speed through the receiving optical fiber, converts the information into an electric signal, and analyzes the electric signal, thereby obtaining the flow velocity of blood in the scalp tissue.

In actual use, the laser dopplerblood flow sensor 700 may be used to obtain blood flow velocity information before use, and then the laserhair growth instrument 10 may be used to perform laser irradiation. After the irradiation for a preset time, the current blood flow rate information is obtained by using the laser dopplerblood flow sensor 700. If the current blood flow rate does not reach the predetermined value, the laser is continuously irradiated or the emitting power of thelaser light source 300 is increased to obtain a better treatment effect.

In the present embodiment, the laserhair growth instrument 10 is a portable laser hair growth instrument. Specifically, in the present embodiment, as shown in fig. 11 to 13, thehousing 100 has a cap shape to enclose the head of the user. That is, in the present embodiment, the laserhair growth instrument 10 is a hair cap. In other embodiments, thelaser hair generator 10 may be a head-wearing structure such as a hair band or a hair band.

In the present embodiment, theshell 100 includes acrown region 110, aforehead region 120, a left side region 130, aright side region 140, and aback cranium region 150. The plurality of laserlight sources 300 are distributed in thecrown region 110 and theforehead region 120. The dotted line in fig. 10 is the boundary between thecrown region 110 and theforehead region 120. Specifically, in the present embodiment, the number of thelaser light sources 300 is 64, 81, 100, 202, or 272.

In traditional cap of growing hair, the parietal region, forehead district, left lateral region, right side district and the back of the head district of shell all are provided with laser source, and laser source's figure is many, leads to the cost of cap of growing hair higher. In practical applications, the hair loss in thetop area 110 and theforehead area 120 of the head of the user is relatively severe, while the hair loss in the left side area 130, theright side area 140 and theback head area 150 is relatively light, and thelaser light sources 300 are arranged in thetop area 110 and theforehead area 120, but thelaser light sources 300 are not arranged in the left side area 130, theright side area 140 and theback head area 150, so that the purpose of treating the hair loss can be achieved, the number of thelaser light sources 300 can be reduced, and the cost of the laserhair growth instrument 10 can be reduced.

In the present embodiment, thecircuit board 200 is disposed on thecrown region 110 and theforehead region 120, and extends to the left region 130, theright region 140, and the back of thehead region 150. That is, in the present embodiment, the area of thecircuit board 200 is larger than the arrangement area of the plurality of laserlight sources 300, so that it is convenient to provide other functional elements, such as a temperature sensor, a humidity sensor, and the like, on thecircuit board 200.

In this embodiment, thecircuit boards 200 are two, and the twocircuit boards 200 are distributed on the left and right sides of the center line of the corresponding head of thehousing 100. In this manner, it is more convenient to arrange thecircuit board 200 such that thecircuit board 200 matches the shape of thehousing 100.

In the present embodiment, thefunctional film 400 is a single piece, and thefunctional film 400 is disposed on thecircuit board 200 and covers thecrown region 110 and theforehead region 120. In this manner, the assembly of thefunctional film 400 is more facilitated. It is understood that thefunctional film 400 may be multiple pieces in other embodiments. For example, thefunctional film 400 may be two pieces, one piece being disposed corresponding to theparietal region 110 and the other piece being disposed corresponding to theforehead region 120; for another example, when thecircuit board 200 is two, thefunctional films 400 may be four, wherein each twofunctional films 400 are disposed corresponding to one circuit board 200 (the twofunctional films 400 correspond to theleft vertex region 112 and theleft forehead region 122 on the lower side of fig. 12), and onefunctional film 400 is disposed corresponding to thevertex region 110 and the otherfunctional film 400 is disposed corresponding to theforehead region 120 in the twofunctional films 400 corresponding to thesame circuit board 200.

In this embodiment, thefunctional film 400 completely covers the inner surface of thehousing 100, and the edge of thefunctional film 400 is wrapped with the edge of thehousing 100, so as to form a closed protection cavity, so as to limit thecircuit board 200 in the protection cavity.

In this embodiment, the laserhair growth instrument 10 further includes a heat sink. The heat sink is disposed between thecircuit board 200 and thehousing 100. The fins are multiple pieces distributed over thecrown area 110 and theforehead area 120. In this way, when the laserhair growth instrument 10 is in operation, the heat sink can transfer heat generated by the operation of thelaser light source 300 to thehousing 100 through thecircuit board 200. Furthermore, the heat dissipation fins are disposed on thecrown area 110 and theforehead area 120, but not on the left area 130, theright area 140, theback head area 150, and other areas, so as to reduce the cost and avoid the weight of the laserhair growth device 10 from being too heavy due to the addition of many heat dissipation fins.

In this embodiment, the heat sink is a metal sheet. Therefore, the laserhair growing instrument 10 has a good heat dissipation effect, and the laserhair growing instrument 10 has light weight.

In order to facilitate the placement of heat sinks in the areas of thecircuit board 200 corresponding to thecrown area 110 and theforehead area 120, no short-circuit issues need to be considered. In the present embodiment, thecircuit board 200 is provided with an insulating and heat conducting layer between the heat sink and thecircuit board 200. The insulating heat conduction layer can be heat conduction glue with good heat conduction performance.

In the present embodiment, an end of the heat sink away from thecircuit board 200 is disposed through thehousing 100 and exposed from an outer surface of thehousing 100. Thus, the end of the heat sink away from thecircuit board 200 can directly contact with the outside atmosphere, which is more beneficial to heat dissipation. Specifically, in the present embodiment, an end of the heat sink away from thecircuit board 200 is inserted into the heat dissipation through hole of thehousing 100 in an interference manner. Thus, the laserhair growth instrument 10 not only has a good heat dissipation function, but also has good dustproof and waterproof functions.

In this embodiment, the laserhair growth instrument 10 further includes asignal line 800, one end of thesignal line 800 is connected to thecircuit board 200, and the other end is used for connecting to a power supply system. Specifically, in the present embodiment, one end of thesignal line 800 away from thecircuit board 200 is aUSB interface 810. Therefore, the laserhair growth instrument 10 is very convenient to be connected with a power supply system, and the power supply system can be a power supply system which is easy to carry by a charger and a notebook.

In this embodiment, the laserhair growth instrument 10 further includes a pad, and the pad is detachably disposed in thehousing 100 and corresponds to the posterior cerebral-cephalic region, so that the laserhair growth instrument 10 can be suitable for at least two heads with different sizes. When wearing thelaser generator 10, the use or non-use of the pad can be selected depending on the size of the head, thereby matching heads of different sizes.

Specifically, in the present embodiment, the pad is an elastic pad or an inflatable pad. Thus, the laserhair growth instrument 10 can be matched with more heads with different sizes.

In this embodiment, the laserhair growth instrument 10 further includes a cap, and thehousing 100 is detachably connected to the cap. Wherein, the cap can hide elements such as theshell 100, thecircuit board 200, thelaser light source 300 and thefunctional film 400, and the external structure of the laserhair growth instrument 10 can be changed by replacing different caps, so as to meet the diversified requirements of the user on the laserhair growth instrument 10.
