Description

Technical Field

[0001] The utility model relates to the field of beauty instruments, in particular to a beauty instrument. Background Art

[0002] A beauty instrument is a device for skin care and beauty. An ultrasonic beauty instrument using ultrasonic technology is one of them. It has the functions of softening blood clots, eliminating scars after acne healing, eliminating abnormal skin pigmentation, differentiating pigments and removing subcutaneous spots. Existing ultrasonic beauty instruments generally adopt a design in which a plastic upper shell and a lower shell are wrapped around a differential ultrasonic working unit. In order to prevent the instrument body from sliding due to vibration when the ultrasonic beauty instrument is working, a cushioning rubber pad is provided at the bottom of the instrument body. For the sake of beauty, the existing rubber pad is generally covered with glue on the surface of the bolts used to fix the upper and lower shells. The glue easily penetrates into the intersection of the bolts and the shell during gluing, resulting in double fixation of the bolts, which affects the subsequent disassembly and maintenance of the beauty instrument by maintenance personnel. In order to solve this problem, a new type of beauty instrument is needed. Utility Model Content
