The embodiment of the utility model provides an electric toothbrush has a detachable brush head 100 and a brush holder 200, which are connected by a connecting rod 210 on the brush holder 200.

As shown in fig. 1, the connecting rod 210 of the electric toothbrush of the present invention preferably has a rotation stop portion 211, a stopper portion 212, and a locking portion 213.

As shown in fig. 1, 2 and 3, the front end of the rotation stopping portion 211 is a semi-cylinder, and the structure of the semi-cylinder can ensure that the structure connected with the semi-cylinder does not generate relative motion when the connecting rod 210 swings circumferentially; the limiting part 212 is located between the rotation stopping part 211 and the clamping part 213 and is in an annular protruding structure; the limiting portion 212 is used to fix the connecting rod 210 in the motor without falling off. The clamping part 213 is fixed in the motor inside the brush handle 200, the motor drives the connecting rod 210 to move, and the connecting rod 210 drives the cutting sleeve 110 and the brush head 100 to move, so as to achieve the purpose of assisting tooth brushing.

Preferably, the motor in the brush holder 200 is a magnetic suspension sound wave motor, and the motor can drive the motor shaft to swing circumferentially; the bristles on the brush head are copper-free bristle-implanted toothbrush heads, the inclination angle of the bristles is set to be 10 degrees in the axial direction, the brush head is formed by injection molding of materials with certain softness, and the structure with softness can improve the swinging effect of the bristles; when the motor starts to operate, the motor drives the connecting rod 210 to generate high-frequency vibration, and further drives the ferrule 110 and the brush head to generate circumferential swing of about 10 degrees, so that the pasteurization tooth brushing method is met.

As shown in figures 2, 3 and 4,

the brush head 100 is provided with a ring-shaped clamping groove 101 and a strip-shaped ribbed plate 102;

the cutting sleeve 110 is also provided with an annular clamping block 111 and a strip-shaped reinforcing rib 112;

the annular clamping groove 101 is matched with the annular clamping block 111 in structure, so that the clamping sleeve 110 can be prevented from falling off from the brush head 100 after clamping;

the ribs 102 form a group, and a certain gap is formed between the two ribs, and the gap is the same as the thickness of the reinforcing rib 112, so that after the reinforcing rib 112 is placed between the gaps of the two ribs, relative movement between the ferrule 110 and the brush head 100 is not easy to generate.

It should be noted that the number of matching ribs 102 and ribs 112 need not be the same, and only one set of matching ribs 102 and ribs 112 may produce the same effect, for example, only one pair of ribs, but having multiple ribs does not affect the fixation of the ferrule and the brush head.

As shown in fig. 4, a splicing ring 113 is disposed on one side of the ferrule 110 close to the handle, and the splicing ring 113 is attached to the bottom of the cavity of the brush head 100 to seal the cavity, so that the brush head 100 looks more beautiful after the ferrule 110 is installed.

As shown in fig. 4, a pair of notch grooves 114 is further formed on one side of the ferrule 110 away from the handle, and when the ferrule 110 is installed in the brush head 100, the notch grooves 114 release the strain force generated during the installation process of the ferrule 110; when the rotation stop portion 211 is inserted into the ferrule 110, the notch groove 114 is deformed to provide pressure to the rotation stop portion, thereby preventing the brush head of the electric toothbrush from falling off during use.

It should be noted that the number of the notch grooves 114 may be plural, and the number and the size of the notch grooves do not disable the structure.

As shown in fig. 5, a toothbrush body 200 of the electric toothbrush has an integrated housing 220, and the integrated housing 220 can reduce water inflow.

Install a waterproof button 230 on the integral type shell 220, this waterproof button 230 has two-layer structure, and one deck is the button body 231, and the other deck is waterproof layer 232, and the button body 231 is arranged in waterproof layer 232's top, and the waterproof layer 232 can fill up the small space between button body 231 and the integral type shell 220, has further reduced into water.

As shown in fig. 6, the toothbrush body 200 includes an integrated housing 220 and a toothbrush inner container 240, and a wireless charging module 241 is provided at the bottom of the toothbrush inner container 240, and the wireless charging module 241 can prevent water from entering when a user replaces a battery.

As shown in fig. 6 and 7, the toothbrush inner container 240 can be preferably fixed by a snap: the edge of the toothbrush inner container 240 is provided with a fixed buckle 242, the inside of the integrated shell 220 is provided with a clamping groove 221, and the clamping groove 221 is matched with the fixed buckle 242 and is not easy to fall off after installation.

As shown in fig. 8, a limiting ring 222 is arranged inside one end of the integrated shell of the electric toothbrush, which is close to the brush head, the diameter of the limiting ring is smaller than the axial length of the motor of the electric toothbrush, and the limiting ring can be arranged at the position of the motor

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
