Referring to fig. 1, the present application provides anelectric toothbrush 100 comprising: abrush bar 10, ahandle 20, asensor 30, acontrol unit 40 and afirst light source 50. Thebrush rod 10 is provided with abrush head 101; ahandle 20 is connected to thebrush bar 10, and thehandle 20 includes ahousing 21 and atouch panel 22 provided on thehousing 21. Thesensor 30 is electrically connected to thecontrol unit 40 and configured to detect the motion state information of theelectric toothbrush 100, thecontrol unit 40 receives the motion state information of theelectric toothbrush 100 and controls the working state of thefirst light source 50 according to the motion state information, thefirst light source 50 is disposed in thehousing 21, a light emitting surface of thefirst light source 50 faces thetouch panel 22, and when thefirst light source 50 emits light, the light emitted by thefirst light source 50 passes through thetouch panel 22 and is emitted to the outside of thehousing 21.

In some embodiments, thesensor 30 is a six-axis sensor, which integrates a three-axis gyroscope and a three-axis acceleration sensor, wherein the three-axis acceleration sensor is used for sensing acceleration in the axial direction of the three-dimensional space X, Y, Z (i.e. the three directions of the front and back, the left and right, and the up and down directions of the three-dimensional space), and the three-axis gyroscope is used for sensing dynamic motions of Roll (left and right tilt), Pitch (front and back tilt), and Yaw (left and right swing), respectively, so that the motion state information of theelectric toothbrush 100 can be detected by thesensor 30 through omnibearing detection of the motion state of thesensor 30. Since thesensor 30 is electrically connected to thecontrol unit 40, when thesensor 30 obtains corresponding motion state information according to the motion state of theelectric toothbrush 100 and transmits the motion state information to thecontrol unit 40, thecontrol unit 40 analyzes the motion state information and controls the operation state of thefirst light source 50 based on the motion state information. For example, when the user holds thehandle 20 of theelectric toothbrush 100, thesensor 30 senses that theelectric toothbrush 100 is displaced or tilted in the three-dimensional space, and obtains the motion state information, and thecontrol unit 40 receives the motion state information signal indicating that theelectric toothbrush 100 is displaced or tilted, and transmits a signal to thefirst light source 50 according to the motion state information signal, so as to control the operation state of thefirst light source 50. Specifically, thecontrol unit 40 may control thefirst light source 50 to emit light, extinguish, decrease or increase the brightness. Because thefirst light source 50 is located inside thecasing 21 of theelectric toothbrush 100, and the light-emitting surface of thefirst light source 50 is disposed toward thetouch panel 22, when thefirst light source 50 emits light, the light passes through thetouch panel 22 along the light-emitting surface to emit outside thecasing 21, so as to illuminate thetouch panel 22, and a user can operate thetouch panel 22 according to the light prompt emitted by thefirst light source 50, thereby conveniently and quickly finding the positions of the function keys, and avoiding wasting unnecessary time by increasing the convenience of using theelectric toothbrush 100. As another example, when the user activates theelectric toothbrush 100, theelectric toothbrush 100 starts to vibrate, and thesensor 30 detects that theelectric toothbrush 100 vibrates to transmit a motion state signal of theelectric toothbrush 100 to thecontrol unit 40. For another example, when the user sets theelectric toothbrush 100 at a certain position after brushing teeth, theelectric toothbrush 100 stops vibrating, and thesensor 30 detects that theelectric toothbrush 100 stops vibrating and is displaced, thereby transmitting a motion state signal of theelectric toothbrush 100 to thecontrol unit 40, so that thecontrol unit 40 controls the operating state of thefirst light source 50 according to the motion state information. In other words, after theelectric toothbrush 100 moves or the movement state is changed, thesensor 30 may detect the movement state information of theelectric toothbrush 100, and thecontrol unit 40 receives the movement state information of theelectric toothbrush 100 and controls the operation state of thefirst light source 50 according to the movement state information.

In this embodiment, theelectric toothbrush 100 can be a pure touch-type electric toothbrush without physical buttons, a semi-touch-type electric toothbrush with partial physical buttons, a conventional button-type electric toothbrush, and the like. Specifically, theelectric toothbrush 100 includes, but is not limited to, sonic toothbrushes, ultrasonic toothbrushes, electric spray toothbrushes, mechanical electric toothbrushes, and the like. In other embodiments, thesensor 30 may also be a three-axis sensor, a nine-axis sensor, a gyroscope, a geomagnetic sensor, a gravity sensor, an infrared sensor, or the like. Optionally, thecontrol unit 40 includes, but is not limited to, a micro control unit, a single chip, a processing chip, and the like, thefirst light source 50 includes, but is not limited to, an incandescent lamp, a fluorescent lamp, a Light Emitting Diode (LED) lamp, and the like, and thetouch panel 22 may be made of glass, polycarbonate, nano silver wire, metal mesh, carbon nanotube, graphene, and the like.

Referring to fig. 1, when the motion state information of theelectric toothbrush 100 changes, thecontrol unit 40 performs pulse width modulation on thefirst light source 50, so that thefirst light source 50 emits light according to a first predetermined rule under the control of thecontrol unit 40, and when the light of thefirst light source 50 passes through thetouch panel 22, thetouch panel 22 displays a display change according to the change of the light emitted by thefirst light source 50. It can be understood that, when theelectric toothbrush 100 moves or the movement state changes, thesensor 30 obtains the corresponding movement state information according to the movement state of theelectric toothbrush 100 and transmits the movement state information to thecontrol unit 40, and thecontrol unit 40 performs pulse width modulation on thefirst light source 50 and sends an electrical signal with a designated frequency, duty ratio and width to thefirst light source 50 to control the operation state of thefirst light source 50. The duty ratio is used to control the brightness of thefirst light source 50, the frequency is used to control the speed of the light brightness change of thefirst light source 50, and the width is used to control the duration of a certain brightness of thefirst light source 50, so that thefirst light source 50 emits light according to a first preset rule under the control of thecontrol unit 40. Optionally, the first preset rule is that thefirst light source 50 alternately performs gradual change of light from bright to dark or from dark to bright. Of course, in other embodiments, the first predetermined rule is that thefirst light source 50 is turned off and then turned on after continuously emitting light according to a fixed brightness, and so on. Alternatively, the first predetermined rule is that thefirst light source 50 is turned on and off gradually, and so on. Still alternatively, the first predetermined rule is that thefirst light source 50 continuously emits light at a constant brightness all the time. Further, after thefirst light source 50 emits light according to a first preset rule, light passes through thetouch panel 22, thetouch panel 22 displays display changes according to the change of the light emitted by thefirst light source 50, and a user performs specific operations on thetouch panel 22 according to the prompt of the display changes of the light of thetouch panel 22, so as to implement various functions and brush teeth.

Referring to fig. 2, in some embodiments, theelectric toothbrush 100 further comprises apower source 70, and apower management unit 80. Thepower management unit 80 is electrically connected to thecontrol unit 40 and is used for detecting the power of thepower supply 70; when thepower management unit 80 detects that the electric quantity of thepower source 70 is lower than the threshold value, thepower management unit 80 sends a prompt signal, and thecontrol unit 40 controls thefirst light source 50 to emit light according to a second preset rule according to the prompt signal. It will be appreciated that thepower source 70 is used to power the components of theelectric toothbrush 100, including but not limited to thesensor 30, thecontrol unit 40, thefirst light source 50, thepower management unit 80, and other components within thehandle 20 that require power, and thepower management unit 80 is electrically connected to thecontrol unit 40 and is used to detect and manage the power level of thepower source 70. In some embodiments, when thepower management unit 80 detects that the power of thepower source 70 is lower than the threshold, for example, the power is lower than 30%, thepower management unit 80 sends a low power prompt signal to thecontrol unit 40, and thecontrol unit 40 controls thefirst light source 50 to emit light according to the second preset rule according to the prompt signal, for example, thecontrol unit 40 controls thefirst light source 50 to reduce the light emission brightness according to the prompt signal, so as to save the power and prolong the service life of theelectric toothbrush 100. Of course, in other embodiments, the threshold value for thepower management unit 80 to detect that the power of thepower source 70 is lower than the predetermined threshold value may be set to 50%, 40%, 20%, 15%, 10%, 5%, etc. of the total power of thepower source 70, and may be adjusted according to the power consumption of thefirst light source 50 by theelectric toothbrush 100 or the use requirement of the user, and is not strictly limited to any one of the above values. Optionally, thefirst light source 50 may emit light according to a second preset rule, which may be a light-emitting rule based on the first preset rule, and the brightness is reduced to a certain extent to form a second preset rule, where if the first preset rule is that thefirst light source 50 alternately changes light from bright to dark or from dark to bright, and the second preset rule is that the brightness is reduced to a certain extent and thefirst light source 50 alternately changes light from bright to dark or from dark to bright, the brightness may be reduced to 30% or 20% of the brightness under the first light-emitting rule, and the brightness reduced by the specific second preset rule may be adjusted according to the difference between the product and the user requirements. Of course, in other embodiments, thefirst light source 50 may emit light according to the second preset rule or may not be adjusted based on the light emitting rule of the first preset rule, and the secondlight source 60 continuously emits light according to a certain brightness to form the second preset rule of emitting light, for example, the first preset rule is that thefirst light source 50 alternately performs gradual change of light from bright to dark or from dark to bright, and the second preset rule is that thefirst light source 50 continuously emits light according to 30% or 20% of the maximum brightness of thefirst light source 50 and there is no brightness change. It should be understood that the above brightness adjustment data is only an example, and during the actual production and use process, the brightness adjustment may be preset and adjusted according to the requirement of the user and the use environment, so that thefirst light source 50 emits light according to the second preset rule.

Referring to fig. 2 and 3, in some embodiments, theelectric toothbrush 100 includes amotor 90, themotor 90 is used for driving thebrush head 101 to move, aswitch sensor 221 is further disposed on thetouch panel 22, theswitch sensor 221 is used for turning on or off themotor 90, a light emitting surface of thefirst light source 50 is disposed toward theswitch sensor 221 of thetouch panel 22, and when thefirst light source 50 emits light, the light emitted by thefirst light source 50 passes through theswitch sensor 221 of thetouch panel 22 and is emitted out of thehousing 21. It can be understood that, when the user picks up theelectric toothbrush 100, thecontrol unit 40 receives the motion state information from thesensor 30 and controls the working state of thefirst light source 50 according to the motion state information, when thecontrol unit 40 transmits the light emitting signal to thefirst light source 50, thefirst light source 50 emits light, the light passes through theswitch sensing key 221 on thetouch panel 22, the light is emitted out of thehousing 21 after theswitch sensing key 221 is lighted, the user finds theswitch sensing key 221 according to the light, after a designated operation is performed, themotor 90 is turned on, and themotor 90 drives thebrush head 101 to rotate or vibrate by using a high-speed vibrating movement to act on the oral cavity of the user, so as to perform tooth brushing. In some embodiments, theswitch sensor key 221 is a virtual key disposed on thetouch panel 22, and has no physical key, and themotor 90 is powered on after the user places a finger on theswitch sensor key 221 for operation, for example, the specified operation may be a long pressing of theswitch sensor key 221 for a preset time, a sliding up or down from theswitch sensor key 221 on thetouch panel 22, at least two continuous taps on theswitch sensor key 221, and so on. Specifically, the preset time interval may be 1 to 30 seconds. Of course, in other embodiments, theswitch sensor key 221 can also be a physical button disposed on thetouch panel 22, and after the user finds theswitch sensor key 221 according to the light, the designated operation of turning on themotor 90 can be pressing theswitch sensor key 221, moving the physicalswitch sensor key 221 up or down on thetouch panel 22, rotating theswitch sensor key 221, etc. to turn on themotor 90, and drive thebrush head 101 to move, so as to brush teeth. Optionally, when theswitch sensor key 221 is a solid key, the solid key may be made of polycarbonate or the like, so as to ensure that light passes through theswitch sensor key 221 and is emitted out of thehousing 21.

Referring to fig. 2 and 4, in some embodiments, theswitch sensor key 221 further includes a light-transmittingportion 2211, the light-transmittingportion 2211 is disposed along a predetermined track on theswitch sensor key 221 to form a predetermined pattern, and when the light emitted from thefirst light source 50 passes through the light-transmittingportion 2211 and is emitted to the outside of thehousing 21, the predetermined pattern appears on theswitch sensor key 221. Specifically, the light-transmittingportion 2211 is disposed along a preset track on theswitch sensor key 221, and the material or the color of the preset track area on theswitch sensor key 221 is different from that of the non-preset track area, for example, the preset track area where the light-transmittingportion 2211 is located is red when light passes through, and the non-preset track area is other colors when light passes through, when light emitted by thefirst light source 50 passes through the preset track where the light-transmittingportion 2211 is located, because the light-transmittingportion 2211 is red and different from the colors displayed in other areas, the light-transmittingportion 2211 displays a preset pattern on theswitch sensor key 221. Certainly, in other embodiments, the preset track area where the light-transmittingportion 2211 is located may also be one color or a set of colors of green, blue, yellow, powder, cyan, orange, white, and the like, and the non-light-transmittingportion 2211 area on the switchinductive key 221 may be one color or a set of colors of black, white, gray, green, blue, yellow, powder, cyan, orange, and the like, where the color displayed when the light passes through the preset track area where the light-transmittingportion 2211 is located may be different from other areas, and the preset track area where the light-transmittingportion 2211 is located may also be set as a transparent area, and the user is prompted according to the color of thefirst light source 50 itself. By using the principle that different colors have different degrees, the light-transmittingportion 2211 is arranged on the switch induction key 221 to achieve the purpose of prompting a user, and the user can specifically operate theelectric toothbrush 100 according to the color of the corresponding area.

Referring to fig. 6, thehandle 20 further includes awaterproof layer 23, and thewaterproof layer 23 covers thetouch panel 22. It can be understood that theelectric toothbrush 100 needs to be constantly contacted with water flow during daily use, and components inside theelectric toothbrush 100 can be electrically leaked or damaged due to contact with water, so that the enhancement of the waterproof performance is beneficial to the improvement of the usability of theelectric toothbrush 100, and the waterproof performance is a problem which must be faced by the pure touch typeelectric toothbrush 100 without physical keys, the semi-touch typeelectric toothbrush 100 with partial physical keys, or the traditional touch typeelectric toothbrush 100. In some embodiments, thetouch panel 22 of theelectric toothbrush 100 requires a user to perform a touch operation, and residual moisture carried on a finger of the user contacts thetouch panel 22, so that the user cannot operate thetouch panel 22, and further, the components in thehandle 20 may be damaged or thetouch panel 22 may malfunction, and therefore, thehandle 20 includes thewaterproof layer 23 and thewaterproof layer 23 covers thetouch panel 22, so that the waterproof performance of thetouch panel 22 may be improved, and the service life of theelectric toothbrush 100 may be prolonged. Specifically, thewaterproof layer 23 may be attached, fastened or fixed to cover thetouch panel 22. Of course, for a conventional push-button toothbrush, thewaterproof layer 23 may be covered on thetouch panel 22 having the physical buttons to waterproof theelectric toothbrush 100.

It is understood that theelectric toothbrush 100 further has avoice output unit 91 and thevoice output unit 91 is electrically connected to thecontrol unit 40, and thevoice output unit 91 can be disposed on thehandle 20 of theelectric toothbrush 100, specifically on thehousing 21 near thetouch panel 22, or on the bottom of thehousing 21, or on the surface which can be far away from thetouch panel 22. Alternatively, referring to fig. 8, thevoice output unit 91 may be further provided on thebrush bar 10 of theelectric toothbrush 100. In some embodiments, thevoice output unit 91 of theelectric toothbrush 100 is a speaker provided on theelectric toothbrush 100, and when thesensor 30 obtains corresponding motion state information according to the motion state of theelectric toothbrush 100 and transmits the motion state information to thecontrol unit 40, thecontrol unit 40 is configured to control thevoice output unit 91 to output a voice corresponding to the light emitting state of thefirst light source 50 according to the light emitting state of thefirst light source 50. For example, when thesensor 30 detects that theelectric toothbrush 100 starts to move or the movement state changes, it sends movement state information to thecontrol unit 40, thecontrol unit 40 controls thefirst light source 50 to emit light, thevoice output unit 91 outputs corresponding voice, such as "light source on, electric toothbrush in standby", and when thecontrol unit 40 controls thefirst light source 50 to be completely turned off, thevoice output unit 91 outputs corresponding voice, such as "light source off, electric toothbrush off". Of course, in other embodiments, the correspondingvoice output unit 91 may be an audio device externally connected to thecontrol unit 40, or another device such as an earphone worn by the user, and the voice output by thecontrol unit 40 according to the light-emitting state of thefirst light source 50 may be changed, and is not limited to the voice type described in the above example.

It can be understood that the conventionalelectric toothbrush 100 generally only has a simple tooth brushing function, and the expanded functions of the conventional electric toothbrush are generally only for adjusting the tooth brushing time, the tooth brushing intensity, and the like, and in this embodiment, theelectric toothbrush 100 further includes a secondlight source 60 and asecond power switch 61, a user can use the secondlight source 60 as an illuminating lamp, after the secondlight source 60 is turned on by thesecond power switch 61, the secondlight source 60 continuously emits light, the light is disposed outside thehandle 20, and the user can irradiate the oral cavity or teeth and other parts with the light emitted by the secondlight source 60, so as to implement the illumination operation, and enrich the functions of theelectric toothbrush 100. Thesecond power supply 60 is disposed in thesecond power switch 61 and on thetouch panel 22, and thesecond power supply 60 is turned on when thesecond power switch 61 is touched. Alternatively, as shown in fig. 10, thesecond power supply 60 may also be disposed on thecasing 21 and thesecond power switch 61 is disposed on thetouch panel 22, or as shown in fig. 11, thesecond power supply 60 and thesecond power switch 61 are disposed on thecasing 21 at the same time. Further, in other embodiments, the secondlight source 60 is electrically connected to thecontrol unit 40, and when thesecond power switch 61 is turned on, thecontrol unit 40 receives the motion state information of theelectric toothbrush 100 and controls the operating state of the secondlight source 60 according to the motion state information, so that the secondlight source 60 emits light under the control of thecontrol unit 40. Specifically, thefirst light source 50 can be referred to for the light emitting rule and principle of the secondlight source 60, but when thesecond power switch 61 turns off the secondlight source 60, thecontrol unit 40 cannot control the secondlight source 60 to emit light, and the user can selectively turn on or off the secondlight source 60 according to the requirement, so as to save the electric quantity of theelectric toothbrush 100 and prolong the service life of the electric toothbrush.

when the user moves theelectric toothbrush 100 in a three-dimensional space or changes the motion state of theelectric toothbrush 100, thesensor 30 senses that theelectric toothbrush 100 is displaced or tilted in the three-dimensional space, and thus obtains the motion state information of theelectric toothbrush 100, so as to obtain the motion state information of theelectric toothbrush 100; the specific operation may be that the user picks up theelectric toothbrush 100, starts theelectric toothbrush 100 and theelectric toothbrush 100 starts to vibrate, stops vibrating after theelectric toothbrush 100 is turned off, places theelectric toothbrush 100 at a certain position after the user finishes brushing teeth, and the like, and thesensor 30 may sense that theelectric toothbrush 100 starts to move or the movement state changes, and sequentially obtains the movement state information of theelectric toothbrush 100.

Since thesensor 30 is electrically connected to thecontrol unit 40, thecontrol unit 40 receives the motion state information signal from thesensor 30, and controls the operation state of thefirst light source 50 according to the motion state information of theelectric toothbrush 100. Specifically, thecontrol unit 40 may control thefirst light source 50 to emit light according to a first predetermined rule or a second predetermined rule. Optionally, the first preset rule is that thefirst light source 50 alternately performs gradual change of light from bright to dark or from dark to bright. Of course, in other embodiments, the first predetermined rule is that thefirst light source 50 is turned off and then turned on after continuously emitting light according to a fixed brightness, and so on. Or the first preset rule is that thefirst light source 50 is turned off after being gradually turned on, and the operation is repeated according to the first preset rule. Or the first preset rule is that thefirst light source 50 continuously emits light at a constant brightness all the time. Further, after thefirst light source 50 emits light according to a first preset rule, light passes through thetouch panel 22, thetouch panel 22 displays display changes according to the change of the light emitted by thefirst light source 50, and a user performs specific operations on thetouch panel 22 according to the prompt of the display changes of the light of thetouch panel 22, so as to implement various functions and brush teeth. Of course, in other embodiments, thecontrol unit 40 may also control thefirst light source 50 to emit light according to a second preset rule. Optionally, thefirst light source 50 may emit light according to a second preset rule, which may be a light-emitting rule based on the first preset rule, and the brightness is reduced to a certain extent to form the second preset rule, where if the first preset rule is that thefirst light source 50 alternately performs gradual change of light from bright to dark or from dark to bright, and the second preset rule is that the brightness is reduced to a certain extent and thefirst light source 50 alternately performs gradual change of light from bright to dark or from dark to bright, the brightness may be reduced to 30% or 20% of the brightness under the first light-emitting rule, and the reduced brightness of the specific second preset rule may be adjusted according to different requirements of products and users. Optionally, thefirst light source 50 emits light according to the second preset rule or does not adjust the light emitting rule based on the first preset rule, and the secondlight source 60 continuously emits light according to a certain brightness to form a second preset rule for emitting light, for example, the first preset rule is that thefirst light source 50 alternately performs gradual change of light from bright to dark or from dark to bright, and the second preset rule is that thefirst light source 50 continuously emits light according to 30% or 20% of the maximum brightness of thefirst light source 50 and does not have brightness change. It can be understood that the above brightness adjustment data is only an example, and in the actual production and use process, the brightness adjustment may be preset and adjusted according to the requirement of the user and the use environment, so that thefirst light source 50 emits light according to the first preset rule or the second preset rule.
