Description

A three-sided cleaning electric toothbrush with rotatable brush head

Technical Field

The utility model relates to the field of toothbrushes, in particular to a three-side cleaning electric toothbrush with a rotatable brush head.

Background Art

Traditional electric toothbrushes use a power transmission shaft extending from the main body of the toothbrush to drive the toothbrush head to move, and then use the brush head to clean teeth. The power transmission shaft between the brush head and the handle of the existing electric toothbrush is not ideal for waterproofing through interference fit with the sealing ring, so that the position is prone to water leakage and seepage, causing damage to the electric toothbrush motor and circuit components, and shortening the service life of the toothbrush. In addition, the gap between the brush head and the handle is prone to dirt accumulation and breeding of microorganisms, which has an adverse effect on human health. Therefore, an electric toothbrush with a waterproof structure is needed;

According to the application number: CN202320661068.9, an electric toothbrush with a waterproof structure is provided. The solution wraps the gap space originally designed for the relative movement between the brush head and the toothbrush body through the presence of a sealing part and a reinforcing ring, thereby avoiding the accumulation of dirt and the breeding of microorganisms, improving the waterproof performance and being more hygienic and healthy;

However, when in use, since the angle of the toothbrush is fixed, when it is necessary to fully clean the oral cavity, the direction and angle of the toothbrush for cleaning the oral cavity are generally changed by manually rotating the wrist to drive the toothbrush to rotate. For people with inconvenient wrist movements, it is not convenient to change the direction and angle of the toothbrush in time when brushing teeth, which is not conducive to fully cleaning the oral cavity. The electric toothbrush mentioned in the above patent is not convenient to rotate the brush head of the toothbrush when brushing teeth, which is not conducive to improving the cleaning of the user's oral cavity;

Therefore, a three-sided cleaning electric toothbrush with a rotatable brush head is needed.
