Problems solved by technology

[0002] In daily life, people usually use a manual toothbrush to clean their teeth. The manual toothbrush is composed of bristles and brush rods. When it is brushed vertically, it seems cumbersome and difficult to clean; It can only rotate 90° with the brush body, so the dirt in the gaps between the teeth cannot be cleaned
Electric toothbrushes in the prior art generally connect the drive shaft and the main shaft of the motor through a coupling, so the transmission efficiency is low and the noise is large

Abstract

The invention relates to an electric toothbrush which comprises a shell, a brush head, a first spiral bevel gear, a second spiral bevel gear and a driving motor, the brush head is connected with the second spiral bevel gear, the first spiral bevel gear is in transmission connection with the second spiral bevel gear, the first spiral bevel gear is arranged above the driving motor and is in transmission connection with the driving motor, and the central axis of the first spiral bevel gear is perpendicular to the central axis of the second spiral bevel gear; and the driving motor is provided with a stepped shaft connected to the first spiral bevel gear. The first spiral bevel gear and the second spiral bevel gear are adopted to drive the brush head to rotate, driving is stable, and transmission efficiency is high; and the stepped shaft is adopted as the main shaft of the driving motor, the transmission efficiency can be improved, transmission is more stable, due to the fact that a coupler in the prior art is simplified, noise generated in the transmission process can be reduced, disordered shaking of the brush head in the rotating process is reduced, the use experience of a user is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of toothbrushes, in particular to an electric toothbrush. Background technique [0002] In daily life, people usually use a manual toothbrush to clean their teeth. The manual toothbrush is composed of bristles and brush rods. When it is brushed vertically, it seems cumbersome and difficult to clean; It can only be rotated by 90° with the brush body, so the dirt in the gaps between the teeth cannot be cleaned. The electric toothbrush in the prior art generally connects the drive shaft and the main shaft of the motor through a coupling, so the transmission efficiency is low and the noise is large. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a simple structure, drive the first spiral bevel gear and the second spiral bevel gear to rotate through the motor, and then drive the brush head to rotate 360°, the transmission is ...
