Electric toothbrush

Abstract

The invention discloses an electric toothbrush, belonging to the technical field of living goods. In order to ensure that the toothbrush can be used for better cleaning teeth, the electric toothbrush adopts the following technical measures: a brush head 4 is arranged on a handle 2, the handle 2 is a Y-shaped structure, the brush head 4 is formed by forming an I-shaped skeleton which consists of two circular discs and one cylinder and planting brush hairs on the inner surface of the I-shaped skeleton, a motor 1 is arranged on the handle 2, a rotating shaft 3 of the motor 1 is provided with a worm rod 5, a rotating shaft of the brush head 4 is provided with a worm wheel 6, the worm rod 5 is meshed with the worm wheel 6 together, and the motor 1 can be used for driving the brush head 4 to rotate by virtue of the worm rod 5 and the worm wheel 6. By virtue of the mode, the electric toothbrush disclosed by the invention has the advantages that because the foremost end of the electric toothbrush is provided with the brush hairs, and the brush head of the electric toothbrush can rotate infinitely instead of performing small-range swing as existing manual toothbrushes and electric toothbrushes, the problems of motion delay, amplitude decrease and the like caused by soft brush hairs can be effectively solved by the electric toothbrush, and the cleaning of innermost cheek teeth and wisdom teeth in the oral cavity can be effectively improved.

During this process, in order for the bristles to rub against the teeth, the user needs to continuously apply up-and-down or back-and-forth linear motions to the toothbrush. But, because the bristles have softness, it makes the friction between the bristles and the teeth lag behind the linear motion of the handle, and the softness of the bristles also makes the friction range between the bristles and the teeth much smaller than the motion range of the handle. For these reasons, combin...
