Description

Technical Field

[0001] The invention relates to the field of cosmetic auxiliary technology, and in particular to a cosmetic lotion pump with leak-proof structural characteristics. Background Art

[0002] Lotion pump is a pump structure that is used by manual pressing. This pump structure is widely used in cosmetics and daily chemical products. At present, the domestic market has more and more requirements and styles for the use of bath and cosmetics. However, there are not many types of lotion pump products, and the functional requirements cannot keep up. They cannot meet more technical requirements, and the product performance stability is low. It is difficult to maintain stable quality for high-demand packaging products, the sealing is poor, and it is very easy to leak.

[0003] After searching for patents, the existing patent number is 201620766731.1. The invention embodiment provides a lotion pump, which belongs to the field of lotion pumps. The lotion pump includes a pump head and a catheter, the pump head is movably connected to the catheter, the inner surface of one end of the catheter is provided with a rotation area, the rotation area is provided with a plurality of limit strips, the arc between each two adjacent limit strips forms a preset angle, and the pump head is embedded in the rotation area and connected to the catheter. The lotion pump uses the limit strips provided on the catheter so that when the pump head and the catheter are connected and rotated, they can rotate relative to the catheter within a maximum rotation range of 30 degrees, so that the pump head can rotate to the angle required by the user.

[0004] Based on the above, the existing cosmetic lotion pump structure design is relatively traditional, the use effect is slightly poor, and the protective function is relatively simple. The protective cover set in the existing lotion pump structure is mostly a separate structure, which is easy to be lost during use, and thus cannot protect the pressing device of the lotion pump well. Moreover, the existing lotion pump can be pressed when not in use, which causes accidental touching, resulting in leakage of lotion and waste. Moreover, the liquid output of the existing lotion pump structure cannot be controlled, so it is easy to squeeze too much and cause waste.

[0005] Therefore, the existing structure and defects are studied and improved, and a cosmetic lotion pump with leak-proof structural characteristics is provided, in order to achieve the purpose of having more practical value. Summary of the invention
