Technical Field

The invention belongs to the field of hairdressing or shaving equipment of personal or household articles in human life necessity, and particularly relates to a piezoelectric vibration face cleaning instrument brush head.

Background

At present, the electric facial cleaning instrument on the market mainly cleans facial skin by means of the operation of components such as a motor-driven brush and the like, and the existing motor-driven structural mode has the defects of complex structure, higher processing precision requirement and higher processing cost, and seriously limits the application of the electric facial cleaning instrument in the production practice, so that the design of the piezoelectric vibration facial cleaning instrument with simple structure and convenience for large-scale production is very important.

Disclosure of Invention

In order to solve the problems that the structure of a driving part motor adopted in the existing face cleaning instrument is complex, the requirement on processing precision is high, and the processing cost is high, a piezoelectric vibration face cleaning instrument brush head is provided, the piezoelectric vibration face cleaning instrument brush head is composed of a base, a shell and a piezoelectric vibrator, the piezoelectric vibrator applies alternating voltage and generates reciprocating bending deformation, stress is transmitted to brush hair after passing through a base boss and a base bottom plate, the brush hair generates small vertical vibration, the skin is deeply cleaned in the vertical direction, and dirty objects are shot from the deep part of a pore. Compared with the vibration mode formed by driving a crank slider mechanism by a motor adopted by the existing massage appliance, the piezoelectric direct drive has the advantages of simple structure, strong tolerance, high power density, less heat generation, no electromagnetic wave interference and the like, and particularly, the drive and vibration forming process does not need a transmission and sealing structure, thereby prolonging the service life and improving the energy conversion efficiency.

In order to achieve the purpose, the invention adopts the following technical scheme:

the invention relates to a brush head of a piezoelectric vibration face cleaning instrument, which comprises: base, shell 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 circular boss is arranged on the upper end face of the base bottom plate in a wafer structure and serves as a base boss; the shell is a hollow cylindrical shell with an opening at the bottom surface, and a shell sinking groove is arranged at the bottom of the inner side surface of the cylindrical groove; the inner diameter of the shell sinking groove is smaller than that of the shell; the shell is arranged on the outer side of the base, and the upper surface of the boss of the base and the shoulder of the sinking groove of the shell are on the same plane; the piezoelectric vibrator is formed by adhering piezoelectric sheet materials on the surface of an elastic substrate and is arranged between a boss of the base and a shoulder of the shell.

The piezoelectric vibrator is a single-chip piezoelectric vibrator formed by adhering one piece of piezoelectric thin material on an elastic substrate, or a double-chip piezoelectric vibrator formed by adhering two pieces of piezoelectric thin material on two sides of the elastic substrate.

During operation, the shell is held by hand, alternating voltage is applied to the piezoelectric vibrator, the piezoelectric vibrator is subjected to reciprocating bending deformation, the piezoelectric vibrator drives the base and the bristles fixed on the base to vertically vibrate relative to the shell in the bending vibration process, the cleaning capacity is formed, the skin is deeply cleaned in the vertical direction, and dirty objects are 'patted' out from the deep part of a pore.
