Description

Technical Field

[0001] The utility model relates to the technical field of optical beauty equipment, in particular to a handle of a laser beauty instrument. Background Art

[0002] Laser beauty instrument is a device that uses laser technology for beauty treatment. The laser emits a beam of light of a specific wavelength, which acts on different layers of the skin, thereby achieving a variety of beauty effects, such as wrinkle removal, freckle removal, hair removal, and skin rejuvenation. To achieve the above effects, a combination of multiple lenses is required.

[0003] Different cosmetic effects require different lenses, which may require replacement of the lens device or adjustment of the lens combination structure.

[0004] In the prior art, the structure of the handle of a laser beauty instrument usually includes: a handle, a laser tube, a focusing tube, etc. Among them, the laser tube is a multi-component structure, including a tube body and multiple lenses directly installed inside the tube body, gaskets, and other structures. The laser tube and the lenses are designed as a fixed structure, which is assembled in advance and cannot be disassembled. The laser handle product has a service life, that is, the laser handle is a consumable, and usually the laser tube is damaged.

[0005] The defect of the prior art is that all the original lenses of the beauty instrument are stacked and fixed in position. If one of the lens components is damaged, the user cannot replace the single component and cannot calibrate it by himself, resulting in the phenomenon that the beauty instrument is damaged if it is damaged. That is, after the lens is damaged, the beauty instrument cannot be used. Therefore, it is necessary to design a laser beauty instrument handle that does not require user calibration, is easy to replace lenses, and can be used immediately after installation.
