Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed implementation and the specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.

In this embodiment, as shown in fig. 1 to 11, a novel electric toothbrush includes a handle, amotor 1 disposed in the handle, abrush rod 7 movably connected to the handle, and abrush head 5 movably connected to thebrush rod 7, wherein a rotatingmember 2, a transmission rod 3, alinkage rod 4, a rotatingmember 6, and anelastic member 8 are disposed in thebrush rod 7 and movably connected to a rotating shaft of themotor 1; the rotatingpart 2 abuts against one end of the transmission rod 3, the other end of the transmission rod 3 is connected with one end of thelinkage rod 4, and the other end of thelinkage rod 4 is connected with therotating part 6; theelastic piece 8 is wound on the surface of the transmission rod 3, one end of the elastic piece is fixedly connected with the transmission rod 3, and the other end of the elastic piece is fixedly connected with the inner surface of thebrush rod 7; when therotating part 2 rotates, therotating part 2 drives the transmission rod 3 to move longitudinally in a reciprocating manner, the transmission rod 3 and thelinkage rod 4 move in a reciprocating manner, therotating part 6 and thebrush head 5 rotate in a reciprocating manner, and theelastic part 8 moves in a telescopic manner.

In this embodiment, the end face of the rotatingmember 2 is aninclined face 22, the two ends of the inclined face have a height difference, the inclined face is provided with anannular slide way 21, and one end of thetransmission rod 2 abuts against theannular slide way 21 and can slide on theannular slide way 21.

Furthermore, one end of the driving rod 3 is provided with aprotruding portion 31, and the protrudingportion 31 abuts against theannular slide way 21 and can slide on theannular slide way 21.

It should be noted that the motor rotates and drives the rotating piece to rotate relative to the transmission rod, and because the end face of the rotating piece contacting with the transmission rod is an inclined plane, when the rotating piece rotates, the protruding part of the transmission rod contacts with the annular slideway and slides circularly along the annular slideway, and the end of the inclined plane is higher than the end of the transmission rod, so that the transmission rod moves up and down in a reciprocating manner.

In this embodiment, therotating part 6 is provided with amovable area 61 and a connectinghole 62, part of thelinkage rod 4 is located in themovable area 61 and moves, and the other end of thelinkage rod 4 is connected with the connectinghole 62 in a penetrating manner; the other end of the transmission rod 3 is provided with a throughhole 32, and one end of thelinkage rod 4 is connected in the throughhole 32 in a penetrating manner.

Furthermore, therotating part 6 is provided with athrough hole 63, and thebrush head 5 passes through and is clamped in the throughhole 63.

Furthermore, the rotatingpart 6 is further provided with apositioning stopper 64, thepositioning stopper 64 is used for limiting the moving range of thelinkage rod 4 not to exceed themoving area 61, when the electric toothbrush extends into the oral cavity, the electric toothbrush is placed transversely, and under the limit of the positioning stopper, thelinkage rod 4 cannot fall off due to gravity, so that the electric toothbrush cannot normally operate.

It should be noted that two ends of the linkage rod are bent by 90 degrees relatively, the transmission rod reciprocates up and down and drives the linkage rod connected with the transmission rod to reciprocate up and down, and the other end of the linkage rod is connected with the eccentric connecting hole to drive the brush head to longitudinally rotate left and right at a certain amplitude.

In this embodiment, theelastic member 8 is a spring.

The connection end of the spring and the brush rod is a fulcrum, so that the transmission rod moves up and down in the brush rod relative to the brush rod and the reciprocating speed of the up-and-down movement is accelerated; when the transmission rod is arranged at the highest end of the annular slide way, the spring is compressed; the transmission rod is driven by the rotating piece to rotate, and the transmission rod is driven by the elastic force of the spring and the gravity of the transmission rod to move downwards and slide to the lowest end along the annular slide way.

In practical applications, as shown in fig. 5 to 7 and 9 to 11, thebrush head 5 connected with the novel electric toothbrush through the rotatingpart 6 can be a common toothbrush or an interdental brush to achieve different tooth brushing effects.

The working principle of the novel electric toothbrush is as follows:

through insert power supply for the motor and make the motor function, drive and rotate a rotation, when rotating a relative drive line rotation, the transfer line moves along the annular slide that rotates a terminal surface, under the difference in height at annular slide both ends, reciprocating motion's action about realizing to drive the gangbar reciprocating motion about rather than being connected, the gangbar relative activity region reciprocates, and stimulates the brush head simultaneously and does the action of vertically controlling the rotation repeatedly, and it increases the frequency of tooth friction to increase through the brush head vertically controls the rotation, works as electric toothbrush stretches into the oral cavity, and electric toothbrush is for violently putting, and under the spacing of location dog, the gangbar can not drop because of gravity, and leads to electric toothbrush unable normal operating.

The novel electric toothbrush in this embodiment is through setting up the transfer line, converts the revolving force of motor into the brush head and vertically reciprocates after the action and vertically reciprocates and controls the rotation, improves the brush hair head to tooth surface contact surface and make a round trip the frequency of brushing, improves the tooth cleanliness, can not harm the gum yet.

Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
