Description

A spring external type perfume pump structure

【Technical field】

The invention relates to a miniature sprayer, in particular to a structure of a spring external perfume pump.

【Background technique】

At present, there are many micro-sprayers on the market. These micro-sprayers can spray the liquid in the container by pressing the button or the nozzle. The working principle is: using the principle of atmospheric pressure balance, the piston moves in the pump body to make the pump When the gas flows in the body, the pressure becomes smaller, the pressure outside the pump remains unchanged, and a pressure difference occurs between the inside and outside of the pump. The liquid is guided out of the pump body through the pressure difference. Principle: In the same fluid, the flow rate is large, the pressure is small; the flow rate is small, the pressure is strong. These sprayer products are widely used in flowers, hair salons, beauty and other fields, some of which are micro sprayers that press the head cap, mainly used for perfume spraying in the beauty field, or called perfume pumps.
