Description

Technical Field

[0001] The utility model relates to the technical field of beauty instruments, in particular to a novel water-soluble needle. Background Art

[0002] The existing liquid storage water-soluble needles on the market are relatively traditional, with microneedles on one end of the tube body. The products on the market currently act on the skin surface and have a single function, with only the functions of storing liquid, discharging liquid and assisting in the introduction of essence. Since the size of the liquid outlet hole is fixed and unstable, the essence produced cannot be adjusted, resulting in a very poor user experience. If it encounters a viscous essence, the liquid cannot be discharged. If it encounters a thin essence, the liquid discharge is large and fast. The liquid discharge amount cannot be controlled during use, resulting in the user being difficult to operate a large area of ​​skin surface only once during the skin operation process. Instead, it is necessary to load new skin care essences multiple times and operate again until the operation is completed, which seriously causes the loss and waste of skin care essences. This product has only 5 parts, upper and lower tubes, liquid control knobs, needle holders, and protective covers. This product perfectly solves the problems of traditional liquid storage water-soluble needles on the market mentioned above.

[0003] Therefore, we propose a new type of water-soluble needle to solve the above problems. Utility Model Content
