Description

Electric toothbrush Technical Field The utility model relates to the technical field of toiletries, in particular to an electric toothbrush. Background Toothbrushes are known as the most commonly used tooth cleaning appliances for cleaning bacteria, tartar and fine foreign matters adhering between teeth, and can play a role in preventing periodontal disease and protecting oral hygiene and tooth health of people. The electric toothbrush on the market generally comprises a toothbrush head, a toothbrush handle, a transmission rod, a vibration motor, a control board and a battery, so that the vibration motor vibrates to drive the toothbrush head to vibrate together for brushing teeth. The research finds that the motor type of the existing electric toothbrush is limited, mainly uses internal motor vibration as a main component, and part of the electric toothbrush also uses a high-frequency sound wave motor to output vibration, and other electric toothbrushes adopt a mode of small-amplitude sector sweeping by motor and Hall positioning. However, practical verification shows that although the electric toothbrushes can clean teeth to a certain extent, the electric toothbrushes mainly vibrate at one point, the vibration toothbrush only vibrates while the vibration toothbrush does small-amplitude sector sweeping, and once gaps among dental hair bundles of the electric toothbrushes are large, a plurality of clean zebra stripes are reserved, and the electric toothbrushes can only brush back and forth for many times. Therefore, it is difficult to achieve a full-scale cleaning regardless of the vibration means or the cleaning by the small fan sweeping. Of course, in the prior art, in order to improve the cleaning effect, when a part of electric toothbrushes are used, the cleaning frequency and speed of the toothbrushes can be regulated by using the mobile phone APP in an auxiliary way, but the optimization strategy has very limited effect in practical application, and the use strategy that a user holds the electric toothbrushes with hands to brush teeth and uses the other hand to operate the mobile phone APP to regulate is not practical, and the user experience is poor. Therefore, when the existing electric toothbrush is used, no matter vibration or small-amplitude fan sweeping is performed, the existing electric toothbrush cannot be cleaned comprehensively, although APP assists a user in adjusting the cleaning frequency and speed of the toothbrush, effective cleaning of gaps among dental bundles of the electric toothbrush still cannot be achieved, so that the cleaning effect of dental surfaces is poor, and the requirements of the user on deep cleaning of teeth are difficult to meet. Disclosure of utility model The utility model aims to solve the technical problem of providing an electric toothbrush to solve the problems that the cleaning effect of the existing electric toothbrush on the brushing surface is poor and the deep cleaning requirement of a user on teeth cannot be met. In order to solve the technical problems, the technical scheme adopted by the utility model is that the electric toothbrush comprises a brush handle and a driving mechanism arranged in the brush handle, wherein the driving mechanism comprises a first motor, a second motor and a bracket, the first motor is arranged in the bracket, an output shaft of the first motor extends along the axial direction and extends out from one end of the bracket, a connecting seat is arranged at the other end of the bracket, a guide groove is wound on the connecting seat, the guide groove is wavy and is connected end to end, an output shaft of the second motor is connected with a rotating piece, and at least part of the rotating piece is slidably accommodated in the guide groove; When the device works, the output shaft of the first motor vibrates and reciprocally rotates around the axial direction by a preset angle, and the output shaft of the second motor drives the rotating piece to rotate around the axial direction and drives the rotating piece to rotate compared with the connecting seat, so that at least part of the rotating piece moves in the guide groove, and the support and the first motor arranged on the support reciprocally move along the axial direction. In the technical scheme, in order to achieve a better cleaning effect, the utility model designs a novel electric toothbrush which integrates a sweeping brush, namely, the output shaft of a first motor can control the output shaft of the first motor to reciprocally rotate around the axial direction by a preset angle while vibrating, so as to realize small-amplitude fan sweeping; meanwhile, in the utility model, the output shaft of the second motor can drive the bracket and the first motor to do back-and-forth reciprocating motion in the axial direction, so that brushing is realized, the electric toothbrush has stronger cleaning capability, deep cleaning of the tooth surface can be realized, and the use exper
