Description

Technical Field

[0001] This utility model relates to the field of nail polish pump technology, and in particular to an all-plastic nail polish pump structure. Background Technology

[0002] Nail polish pumps are one type of lotion pump. There are many types and structures of lotion pumps, but they generally include components such as a cap, connecting rod, spring, switch, threaded cap, piston, valve stem, pump body, and a ball bearing. The cap, connecting rod, and valve body are statically fitted and can be considered a single unit, while the piston is located between the valve stem and connecting rod. To pump out lotion, press down on the cap. The connecting rod and valve body move downwards, compressing the spring and simultaneously moving the piston downwards, pumping out the lotion pre-stored in the pump body. After the lotion is pumped out, release the pressure. Under the spring's elasticity, the piston, valve body, connecting rod, and cap move upwards, resealing the lotion inside the pump body. Continuously repeating the pressing action will continuously dispense lotion.

[0003] Because existing nail polish pumps use metal springs, the elasticity of the metal springs gradually decreases over time, and the metal springs are prone to rusting, making them unsuitable for long-term use and causing contamination of the liquid.

[0004] Therefore, it is necessary to invent an all-plastic nail polish pump structure to solve the above problems. Utility Model Content
