Description

Technical field

[0001] The present invention relates to the technical field of cosmetics filling, in particular to a piston-type needle semi-automatic filling machine. [Background Technology]

[0002] In the past two years, the use of hydrating injections has become increasingly popular. This type of skincare treatment involves injecting a specialized device called a "hydrating gun" into the dermis, just below the epidermis. The injections are known for their hydration and radiance. With the rise of hydrating injections, more convenient methods have emerged, including the spreadable hydrating injection. This smearable hydrating injection is essentially a smearable essence-like product.

[0003] Whether it is an injectable or smearable hydrating needle, the cosmetic injection is filled into the hydrating needle body, which includes a syringe 10 and a pusher 20 (as shown in Patent No. CN2016210656399). Currently, the hydrating needle cosmetic injection is filled by first withdrawing the pusher 20 from the syringe 10, then inserting the filling head from the rear end of the syringe 10, filling from the top of the syringe 10 to the rear end of the syringe 10, and finally withdrawing the filling head and inserting the top of the pusher 20 into the rear end of the syringe 10 to secure it. The current filling method has many disadvantages, such as cumbersome operation and numerous steps, and the push cylinder 20 needs to be withdrawn first, which may cause contamination to the inner cavity of the syringe 10. For example, after the filling is completed, due to the presence of air at the tail end of the syringe 10, air will exist in the inner cavity of the syringe 10 after the push cylinder 20 is inserted, which is not conducive to the preservation of the cosmetic injection and may affect the stability of the cosmetic injection. After the injection, the cosmetic injection in the inner cavity of the syringe 10 will be squeezed toward the head of the syringe 10 due to the pressure of the air, and a small amount of cosmetic injection will overflow from the needle 11 of the syringe 10, contaminating the needle 11. Moreover, since it is a manual operation, the distance the push cylinder 20 is inserted each time is different, and the amount of cosmetic injection overflowed is also different.
