Sonic electric toothbrush

Abstract

The invention provides a sonic electric toothbrush. The sonic electric toothbrush comprises a toothbrush head, a shell handle, a sonic vibrating module and a power supply module, the shell handle is connected onto the toothbrush head, and the sonic vibrating module and the power supply module are arranged in the shell handle. The sonic vibrating module comprises a replacement head, a driving motorand an elastic V-shaped piece, the replacement head can be used for connecting with the toothbrush head in an operatable manner, the driving motor is arranged in the replacement head and used for providing sonic vibrations for the toothbrush through the replacement head, and the elastic V-shaped piece has two ends respectively and fixedly connected to the driving motor and a counter weight base and is used for receiving the sonic vibrations and restraining the sonic vibration into left and right torsional vibrations. The power supply module is arranged in the shell handle and used for supplying power to the driving motor. The sonic electric toothbrush has the advantages that support stability can be improved effectively, and unexpected vibration transmission can be restrained effectively.

Description

technical field [0001] The present invention relates generally to electric toothbrushes, and more particularly to sonic electric toothbrushes. Background technique [0002] Electric toothbrushes are more effective at cleaning your mouth than regular toothbrushes. It can more thoroughly remove dental plaque, reduce oral diseases such as gingivitis, periodontal disease and gingival bleeding, and is also a generally popular daily necessities in many countries in Europe and America. [0003] The electric toothbrush, through the rapid rotation or vibration of the motor core, causes the brush head to generate high-frequency vibrations, instantly decomposing the toothpaste into fine foam, which can deeply clean the gaps between the teeth. [0004] At present, a sonic toothbrush is a commonly used electric toothbrush. A sonic toothbrush means that the vibration frequency of the bristles / brush head is the same or similar to the frequency of the sound wave, so it is also called a son...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the sonic vibration toothbrush usually does not connect the motor to the replacement head, but directly connects the V-shaped shrapnel to the replacement head, so that it cannot provide good support for the motor, and at the same time cannot provide the necessary support for vibration. barrier, which leads to poor user experience, and unnecessary vibration transmission will also reduce the life of some components
