Problems solved by technology

[0003] However, the existing electric toothbrushes on the market, because the transmission wheel and the transmission shaft are designed in one body, easily interfere with the gears of the transmission device when the transmission shaft senses pressure, resulting in a larger load generated when the electric toothbrush is working, and a shorter battery life. It will also cause high noise, weak cleaning power and light problems, and will also affect the service life of the transmission device

Abstract

The invention discloses an electric toothbrush. The device comprises a transmission wheel, a swing block and a transmission shaft. The transmission wheel is provided with an eccentric sliding block deviating from the central shaft of the transmission wheel. The swing block is provided with a swing sliding groove. The eccentric sliding block of the transmission wheel penetrates into the swing sliding groove. The transmission shaft is connected with the swing block and connected with the toothbrush head of the electric toothbrush. When the transmission wheel drives the eccentric sliding block toslide in the swing sliding groove, the swing block swings in a reciprocating mode so as to drive the toothbrush head of the electric toothbrush to rotate and swing in a reciprocating mode through thetransmission shaft. Through the above device, rotation of the transmission wheel is changed to swing of the swing block, and then primary transmission of the transmission shaft is driven. The transmission shaft and the transmission wheel are arranged separately, so that the transmission shaft is prevented from influencing transmission of the transmission device when sensing pressure. Loads can bereduced. Noise can be reduced. The cruising ability and the cleaning effect of a product are improved, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to an electric toothbrush. Background technique [0002] With the improvement of people's living standards, people's pursuit of a better quality of life is becoming more and more intense. The electric toothbrush uses the rapid rotation or vibration of the motor core to make the brush head generate high-frequency rotating and reciprocating vibrations, which instantly decomposes the toothpaste into fine foam and cleans the teeth deeply. At the same time, the vibration of the bristles can promote blood circulation in the mouth and protect the gums. The tissue has a massage effect. Because electric toothbrush has made things convenient for people's life, has improved people's quality of life, once electric toothbrush comes out, just is widely favored by people. [0003] However, for the existing electric toothbrushes on the market, since the transmission wheel and the transm...
