Abstract

Disclosed is an electric toothbrush for children, comprising a brush head (100), a brush handle (200), and an illumination assembly. The illumination assembly comprises a light-transmitting area (300), an illuminating lamp (500), and a condenser member (400). The condenser member (400) is arranged close to the illuminating lamp (500) and guides light emitted by the illuminating lamp (500) into the light-transmitting area (300). The light-transmitting area (300) is located on a side surface of the brush head (100). In the use of the electric toothbrush, after the illuminating lamp is turned on, the emitted light beam is not directly transmitted to the eyes of the child user. The present invention can also improve the illumination effect.

Technical field

The present invention relates to the field of children's electric toothbrushes, and in particular to a children's electric toothbrush with high light concentration, high definition and downward light source illumination.

Background technique

In order to provide oral lighting, setting and installing lighting equipment on electric toothbrushes has become a common product on the existing market, especially in the field of children's electric toothbrushes. This lighting setup mainly has two functions. One is to increase children's interest in use. , the other is to provide lighting so that parents can clearly understand the children's oral environment and tooth status when operating the electric toothbrush, and can also improve the pertinence and accuracy of the brushing process. Because of the above two points, most parents will choose electric toothbrushes with oral lighting function.

However, the entire brush head of an existing electric toothbrush is a lighting body and has a built-in lighting lamp. It has the characteristics of high brightness to improve the clarity of use and observation in the oral cavity. This structure forms a hand grip on the hands of children who use it. "High illumination light", this kind of electric toothbrush emits a high-brightness beam that directly affects the development of children's eyes, and even leads to the occurrence of eye diseases if viewed for a long time or for a long time.

Therefore, how to avoid the impact of the lighting of an electric toothbrush on children's eyes and ensure the lighting brightness required during use is one of the important technical issues that those skilled in the art need to solve.
