Abstract

The invention relates to a piezoelectric-magnetic pressing facial cleansing instrument brush head which comprises a base, a shell, a plastic shell and a piezoelectric vibrator. The base is composed ofa base bottom plate, a brush seat and bristles; a base vibrator mounting platform is arranged on the upper end surface of the base bottom plate, and the lower end surface of the base bottom plate isconnected with the brush seat; the shell is of a hollow cylindrical shell structure with an opening bottom surface, and a fixed magnet is inlayed in the middle surface of the inner side surface of a cylindrical groove; a free-end mass block is arranged at one end of the piezoelectric vibrator, and the other end of the piezoelectric vibrator is installed in a vibrator installation groove; the samepolar and the position of the free-end magnetic mass block are opposite to the same polar and the position of the fixed magnet; and the plastic shell is bonded to the outside of the base and the outside of the shell, and a gap is reserved between the shell and the base. Magnetic coupling piezoelectric inertial drive is adopted, the piezoelectric-magnetic pressing facial cleansing instrument brushhead has the advantages of simple structure, high tolerance, high power density, less heat generation, no friction pair, no electromagnetic wave interference and the like, the service life is prolonged, especially after a magnetic coupling is used, and the energy converted into elastic potential energy is reduced, so that the energy conversion efficiency is improved.

Description

technical field [0001] The invention belongs to the field of hairdressing or face-shaving equipment for personal or household items necessary for human life, and in particular relates to a brush head of a piezoelectric-magnetic pressing facial cleanser. Background technique [0002] At present, facial electric facial cleansers on the market mainly rely on motors to drive brushes and other components to clean the skin of the face. The existing motor-driven structure has complex structures, high processing precision requirements, and high processing costs, which are severely limited. Therefore, it is very important to design a piezoelectric-magnetic pressure cleansing instrument with simple structure, high energy conversion efficiency and high energy conversion efficiency that is convenient for mass production. Contents of the invention [0003] In order to solve the problems of complex motor structure, high processing precision, high processing cost and low energy conversio...
