Drive structure of cleaning brush head

Abstract

The invention provides a driving structure for a brush head of a cleaning brush. The driving structure comprises the brush head, a motor and a transmission assembly used for being connected between the motor and the brush head in a driving mode, wherein the motor comprises a motor body and an output shaft with one end extending out of the motor body; the transmission assembly comprises a transmission component connected between the brush head and the motor body, an eccentric component installed on the output shaft in the mode that the gravity center of the eccentric component and the center axis of the output shaft are arranged in a staggered way, and a guiding limiting component used for guiding the eccentric component to move perpendicular to the axial direction of the output shaft. By the adoption of the driving structure, large displacement and high-frequency movement of all brush bristles is achieved, and the cleaning efficiency and cleaning effect of a face washing brush are improved greatly; compared with the prior art, the driving structure of the brush head has the advantages of being simple and reliable in structure, small in occupied space, and capable of reducing the manufacturing cost of the face washing brush, improving the performance reliability of the face washing brush, and facilitating miniaturization design of products.

Description

technical field [0001] The present invention relates to the technical field of personal care and cleaning equipment, and more specifically relates to a driving structure of a cleaning brush head. Background technique [0002] The pollution in modern cities is becoming more and more serious. Traditionally, the face is cleaned by hands, but the impurities clogged in the pores of the face are not cleaned by hand washing. If the face is not cleaned for a long time, the pores of the face will be further blocked, which is easy to cause acne, Grease particles, blackheads or pimples make the facial skin not fully absorb skin care products and make the facial skin age rapidly. The facial cleanser is a facial cleansing tool that has emerged in recent years. It mainly uses a driving device to vibrate the fine hairs on the cleaning brush, so as to achieve efficient and non-irritating cleaning and massage effects.

AI Technical Summary

Problems solved by technology

[0003] Existing cleaning brushes usually include a brush head, which is provided with an existing brush head on the market, which is a whole and rotates as a whole. The brush cleaning device has low cleaning efficiency and can only be cleaned in one direction. Can't change the brush in different directions like a brush, the effect of cleaning and washing the face is not good, and the efficiency is low

[0004] In addition, most of the movements of the existing facial cleansing brushes are driven by complex gear structures. The transmission structure is relatively complicated, the transmission reliability is low, and the volume is relatively large, which is not conducive to the miniaturization design of the facial cleansing brushes. The noise is loud during use, and the user experience is not good
