Electric toothbrush

Abstract

The invention provides an electric toothbrush. The electric toothbrush comprises a brush head and a brush body, the brush head comprises a brush head housing, a bristle tuft and an electrical component, the brush head housing encloses a hollow chamber, the hollow chamber of the brush head extends in the length direction of the electric toothbrush up to the position corresponding to the bristle tuft, the electric component is mounted on the position, corresponding to the bristle tuft, of the brush head housing in the longitudinal direction, the brush body can be detachably mounted on the position, in the hollow chamber of the brush head, of the brush head housing, and an electrically conductive assembly has an electrical connection position exposed to the brush body and the electrical connection position is located at one end of the brush body so that electrical connection with the electrical connection position within the hollow chamber of the brush head can be achieved; the brush bodyis partially installed in the hollow chamber of the brush head, the hollow chamber extends to a brush head cluster, the electrical component mounted on the brush head housing is electrically connected with the electrically conductive assembly mounted inside the brush body, and the electrically conductive assembly and the electrical component are connected in the length direction within the rangeof the bristle tuft. The structure of the brush head is simplified and the replacement cost is reduced.

Description

technical field [0001] The present invention relates to cleaning appliances, and in particular to an electric toothbrush. Background technique [0002] The brush head of an electric toothbrush is generally designed to be detachably connected to the brush handle, so that the brush head can be disassembled and replaced with a new brush head when the brush filament is damaged. The brush head is usually jointed on the driving shaft that can generate vibration or swing, and the brush head moves together with the driving shaft to achieve the cleaning effect. [0003] Traditional electric toothbrushes that only rely on brush filaments or characteristic brush filaments to clean the mouth can no longer meet the needs of consumers. Some special oral care functions, such as blue light whitening, radio frequency, and negative ions, have been used in electric toothbrushes. In this kind of electric toothbrush with special functions, it is necessary to lead the current of the power supply...

AI Technical Summary

Problems solved by technology

When replacing the brush head, the fixed body and wires are disassembled together with the brush wire, resulting in a lot of waste

In addition, the connection between the connector and the wire of the brush head is close to the connection between the brush head and the handle, which poses a greater risk in terms of water resistance
