Problems solved by technology

[0005] Second, the brush head of the facial cleansing brush on the market is only installed and fixed by the elasticity of the plastic. This structure is either not firm, or has low durability, or makes it difficult to install.
[0006] Third, the facial cleansing brushes on the market that can automatically identify the brush head and switch the corresponding mode only use the current to distinguish the type of the brush head, and the identification method used is not reliable
[0008] Finally, the fully charged use time of the rechargeable facial cleansing brushes on the market is only about 20 minutes. In the case of travel, the power will be very insufficient.

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] The present invention relates to a sonic facial cleansing brush: comprising a high-frequency swing motor 100, a control module 200, and a brush head;

[0036] The high frequency swing motor consists of an E-shaped electromagnet and an I-shaped swing assembly. The E-shaped electromagnet includes an E-shaped silicon steel core 107 and an inductance coil 106 . The I-shaped swing assembly includes a fixed plastic part 101, a metal elastic piece 102 (one piece or two pieces), a back iron 104 and two permanent magnets 105 placed in opposite directions.

[0037] The fixing plastic part 101 is installed on the housing 500 by two screws and two fixing posts (or four fixing posts). The metal elastic piece 102 is installed on the fixed plastic part 101 by means of screws or inserts. The swinging plastic part 103 is connected to the metal dome 102 by means of screws or i...

Abstract

The invention provides a sound wave face-washing brush. The sound wave face-washing brush comprises a high frequency swing motor, a control module, a wireless charging module, a brush head and a shell. The high frequency swing motor comprises an E-shaped electromagnet and an I-shaped swing assembly, wherein the E-shaped electromagnet comprises an E-shaped silicon steel sheet magnetic core and an inductance coil, and the I-shaped swing assembly comprises a fixing plastic piece, a metal elastic piece, guard iron and two permanent magnets arranged in the opposite directions. According to the sound wave face-washing brush, the swing assembly suitable for high frequency swing with the frequency higher than 500 Hz is manufactured through the I-shaped structure and the unique size of the metal piece, a near-resonance phenomenon is formed by matching a high frequency electromagnetic field generated by the electromagnet, and the phenomenon is utilized to drive the brush head to clean the face.

Description

technical field [0001] The invention relates to a face cleaning device, in particular to a sonic face cleaning brush with high frequency, long use time and wireless high charging efficiency. Background technique [0002] Due to air pollution, the human skin routinely accumulates a lot of dust. Washing the face with only hands, towels and water is difficult to remove all the dirt completely, resulting in many facial skin problems. There are many effective ways to help cleanse the face on the market today, one of which is to use a sonic facial cleanser. [0003] There are two types of sonic facial cleansing brushes on the market today: one is to clean the face by rotating the brush head, and the other is to clean the face by swinging the brush head back and forth. [0004] The oscillation frequency of the latter can only reach below about 300Hz, and the cleaning effect is insufficient. The technical problem to be solved by the present invention is to achieve a face-washing ...
