Problems solved by technology

In actual production and application, the power unit has very high requirements on the consistency of the vibration system, and has very strict requirements on the consistency and precision of the material and hardness after processing. The volume is also large, and the portability is limited to a certain extent, and the practical working frequency is also difficult to develop to a higher end.
[0009] A sonic toothbrush driven by a linear motor. The toothbrush works at two low-frequency frequencies. The main frequen

Abstract

A sound-wave tooth-brush with high cleaning effect and low noise is composed of a brush head, a handle used as its main body, and the axle-swinging motor and its driver, which are arranged in said handle. Said axle-swinging motor consists of supporting frame, electromagnetic coil, swinging axle connected to brush head, two magnets close to another end of swinging axle and a frequency (350-550 H2) regulator.

Description

technical field [0001] The invention relates to an electric toothbrush, in particular to a sonic toothbrush whose toothbrush head vibrates at a low audio frequency to achieve high-efficiency tooth cleaning by means of the "cavitation" effect and a pendulum motor used for the sonic toothbrush. Background technique [0002] The emergence of electric tooth cleaning appliances is expected to replace ordinary manual toothbrushes and dental floss, and efficiently clean plaque and tartar in the interdental spaces. It is easier to clean the food residue accumulated between the teeth and gums, but for the plaque and calculus firmly attached to the surface of the gums, the following two methods are generally used to clean: [0003] 1. Use abrasives to assist mechanical power to directly remove tartar and plaque. This method will cause wear on the surface of the gums. It should be used under the advice of a dentist and is not suitable for daily household use. [0004] 2. Use a certain...
