Description

Technical Field

[0001] This utility model belongs to the field of water light needle technology, specifically relating to an adjustable length multi-needle water light needle component. Background Technology

[0002] Hyaluronic acid injections are actually a type of injectable skincare treatment. During the injection, a special instrument called a "hyaluronic acid gun" is used to inject the desired cosmetic agents into the dermis layer just below the epidermis. After the injection, the skin becomes hydrated and radiant, hence the name.

[0003] Chinese patent application number 202121793202.8 discloses a multi-needle mesotherapy device with adjustable needle tip extension length, including a telescopic mechanism and a negative pressure mechanism disposed at the bottom of the telescopic mechanism. The telescopic mechanism includes a sleeve and a fixed plate slidably connected inside the sleeve. Needle bodies are evenly distributed on the fixed plate, and the needle bodies extend vertically through the fixed plate. A toothed plate is fixedly connected to the top of the fixed plate. The telescopic mechanism also includes a rotating shaft that passes through the sleeve. A gear is fixedly connected to the rotating shaft, and the gear meshes with the toothed plate. By introducing the liquid to be injected into the inlet, and then rotating the rotating block, the rotating block drives the gear on the rotating shaft to mesh with the toothed plate. The toothed plate drives the fixed plate under the rotation of the gear, thereby driving the needle body to move up and down. The top of the needle body slides inside the outlet without affecting the liquid output, realizing convenient adjustment of the extension length of the needle body.
