Compared with the mode that the motor adopted by the existing massage appliance drives the crank slider mechanism to form vibration, the magnetic coupling piezoelectric inertia driving mode is adopted, and the massage appliance has the advantages of simple structure, strong tolerance, high power density, less heat generation, no friction pair, no electromagnetic wave interference and the like, prolongs the service life, and particularly reduces the energy converted into the elastic potential energy after the magnetic coupling is adopted, thereby improving the energy conversion efficiency and saving more energy than the simple piezoelectric inertia driving mode.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention relates to a brush head of a piezoelectric-magnetic pressing face cleaning instrument, which comprises: base, casing, plastic casing and piezoelectric vibrator, wherein:
the base is formed by connecting the lower end surface of a base bottom plate with a brush holder for arranging brush bristles; a rectangular boss is arranged on the upper end face of the base bottom plate in a wafer structure to serve as a base vibrator mounting table; two vibrator mounting grooves are symmetrically arranged on two side surfaces of the base vibrator mounting table; the length direction of the vibrator mounting groove is parallel to the surface of the base bottom plate wafer; the shell is a semi-cylindrical shell structure formed by dividing a hollow cylindrical shell with an opening at the bottom surface along a plane where a central line is located, and a fixed magnet is embedded in the middle surface of the inner side surface of a semi-cylindrical groove; the plastic shell is a hollow cylindrical elastic body with an opening at the bottom surface, is bonded at the outer sides of the base and the shell, and a gap is reserved between the shell and the base; the piezoelectric vibrator is formed by adhering piezoelectric thin material on the surface of an elastic substrate and arranging a free-end magnetic quality block at one end in the length direction, and the other end of the piezoelectric vibrator is arranged in the vibrator mounting groove; the free end magnetic mass block is opposite to the fixed magnet in homopolar and opposite in position.
The two piezoelectric vibrators have the same structure, and adopt a single-chip piezoelectric vibrator formed by sticking a piece of piezoelectric thin material on an elastic substrate with a free-end magnetic mass block or a double-chip piezoelectric vibrator formed by sticking two pieces of piezoelectric thin material on two sides of the elastic substrate with the free-end magnetic mass block.
The during operation, handheld shell, piezoelectric vibrator fixes on the base, applys alternating voltage to piezoelectric vibrator, and it takes place reciprocal bending deformation, and piezoelectric vibrator drives the vibration that fixed brush hair takes place for the casing on base and the base under the reaction of free end magnetic mass inertia power at the flexural vibration in-process, forms the cleaning power, and the vertical direction is clean through carrying out deep skin, and the thing of will dirtying is followed pore depths "clapped" and is gone out. In the motion process of each period, the electric energy is converted into mechanical energy by the piezoelectric material, the mechanical energy comprises mechanical energy stored by bending the piezoelectric vibrator and kinetic energy of the system, after the magnetic structure is added, when the piezoelectric vibrator is bent, the elastic potential energy is increased, but the potential energy between magnetic bodies in the system is reduced, and the two are mutually complemented, so that the mechanical energy converted into the kinetic energy of the system is increased, and the energy conversion efficiency is improved.
