Abstract:
An omnidirectional scientific toothbrush includes a brush handle and a brush head having a U-shaped structure. A central gearset, and tooth outer side brush rollers and tooth inner side brush rollers, both of which are respectively arranged in an upper row and a lower row according to tooth layout, and a tooth end surface brush roller driven by the central gearset are installed in an inner cavity of the brush head. The tooth end surface brush roller is located in a space defined by the tooth outer side brush rollers and the tooth inner side brush rollers. The rotating action of the tooth end surface brush roller allows the tooth end surface brush roller to simultaneously brush occlusal surfaces of Upper and lower rows of teeth. Thus the cleaning operation of all of the teeth in the mouth may just be finished at one time automatically.

Claim (Index 1):
An omnidirectional scientific toothbrush, comprising:\n a brush handle, and a brush head, wherein the brush head has a U-shaped structure, a central gearset, and tooth outer side brush rollers, tooth inner side brush rollers and tooth end surface brush rollers which are driven by the central gearset are installed in an inner cavity of the brush head; the tooth outer side brush rollers and the tooth inner side brush rollers are both arranged in an upper row and a lower row which are opposite according to a tooth layout in an oral cavity of human body, and main body parts of each tooth outer side brush roller and each tooth inner side brush roller are both flexible roller bars, a side brush roller gear is fixedly connected to each flexible roller bar, and bristles are planted onto the flexible roller bars at two sides of the side brush roller gear, the tooth end surface brush roller is located in a space defined by the tooth outer side brush rollers and the tooth inner side brush rollers; and a power output mechanism driven by a micro motor is arranged in the brush handle, the power output mechanism drives the central gearset to move to allow the tooth outer side brush roller and the tooth inner side brush roller located at two sides of the same tooth to rotate in opposite directions and to have rotating directions which are both from a tooth root to a tooth end, and rotation of the tooth end surface brush roller allows the tooth end surface brush roller to simultaneously brush occlusal surfaces of upper and lower teeth in the oral cavity.
