electric toothbrush

Abstract

The invention discloses an electric toothbrush. The electric toothbrush comprises a bracket, a supporting member, a driving device, a hall effect sensor and a brush head which is configured at one endof the bracket and assembled with the driving device, wherein the supporting member is rotatably connected with the bracket; the driving device is assembled on the bracket through the supporting member, and the driving device and the brush head form a lever structure by using a connecting position of the supporting member and the bracket as a fulcrum; the hall effect sensor and the driving deviceare oppositely arranged; a pressure sensing mechanism is arranged between the hall effect sensor and a bracket body, and comprises a metal elastic sheet; a magnet is arranged between the metal elastic sheet and the hall effect sensor, and produces magnetic fields; and the brush head enables the driving device to deflect due to different applied force, the metal elastic sheet is abutted to move relative to the sensor, and the hall effect sensor can induce different detection values through magnetic flux changes of the magnetic fields. Through the adoption of the technical scheme disclosed by the invention, overvoltage protection of the electric toothbrush can be prompted, the tooth brushing intensity of a user can be monitored through data detected by the hall effect sensor, and the user experience is increased.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to an electric toothbrush. Background technique [0002] At present, electric toothbrushes are more and more popular in human life. With the promotion of the market, traditional toothbrushes can no longer meet people's needs. good service. [0003] The electric toothbrush mainly uses the rapid rotation and vibration of the motor core to generate high-frequency vibrations on the brush head, instantly decomposing the toothpaste into fine foam, and cleaning the teeth deeply. Compared with ordinary toothbrushes, electric toothbrushes can more thoroughly remove dental plaque and reduce oral diseases such as gingivitis, periodontal disease and bleeding gums. However, for conventional electric toothbrushes, one is to set the corresponding working mode by itself, and the user only needs to select the current working mode that he wants to use through the fixed button; the other i...

AI Technical Summary

Problems solved by technology

[0004] For the above-mentioned first type of electric toothbrush, the fixed working mode is relatively simple, which will make the user experience poor; while the second type of electric toothbrush only has a pressure sensor detection, but does not rely on the design of the mechanism transmission, which easily makes the pressure detection inaccurate. , there may even be false alarms, resulting in low stability of the electric toothbrush
