Motor for electric toothbrush

Abstract

The invention discloses a motor for an electric toothbrush. The motor comprises an electric toothbrush body and a motor mechanism. An adjusting key is arranged on one side of the outer portion of a shell, an on-off key is arranged at the top of the adjusting key, a fixing ring is arranged at the position, located at the top of the shell, of the top of the on-off key, and a replacement rod is arranged at the top of the fixing ring. According to the motor for the electric toothbrush, the limiting piece arranged in the motor mechanism is matched with the fixing piece, so that the motor mechanismgenerates low noise pollution at the highest vibration frequency, and the vibration frequency of the motor mechanism is 3000 times / min by testing the service life of the motor mechanism. The duty ratio is 45%. The motor for the electric toothbrush can continuously work for 300 hours under rated load and voltage, can work for 100 hours through placement tests at various temperatures and humidity, can reduce noise pollution, prolongs the service life of the motor, avoids frequent replacement of the electric toothbrush, and improves the cost performance.

Description

technical field [0001] The invention relates to the technical field of a sound wave motor, in particular to a motor for an electric toothbrush. Background technique [0002] The electric toothbrush is a toothbrush invented by Philippe-Guy Woog. Through the rapid rotation or vibration of the motor core, the brush head generates high-frequency vibrations, which instantly decomposes the toothpaste into fine foam and cleans the teeth deeply. At the same time, the vibration of the bristles It can promote blood circulation in the mouth and has a massage effect on the gum tissue. In 1954, Swiss doctor Philippe-Guy Woog invented the electric toothbrush. 60 years later, the electric toothbrush is actually very similar to this predecessor. In principle, there are two types of electric toothbrushes: rotation and vibration. The principle of rotary toothbrushes is simple, that is, the electric motor drives the round brush head to rotate, which enhances the friction effect while performi...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional electric toothbrush produces a lot of noise pollution due to the high vibration frequency during use. In addition, due to the unavoidable water ingress during brushing, the working life of the internal motor is shortened, which leads to frequent replacement of electric toothbrushes, resulting in lower cost.
