2.Working principle

Manually press the pressing handle downward, the volume in the spring chamber is reduced, the pressure is increased, the liquid enters the nozzle cavity through the hole of the valve core, and then the liquid is ejected outward through the nozzle. At this time, the pressing handle is released, and the spring cavity is released. The volume increases, a negative pressure is formed, the sphere opens under the action of negative pressure, and the liquid in the bottle enters the spring chamber. At this time, there is already a certain liquid in the valve body, and the liquid stored in the valve body when the handle is pressed again Rush up and spray through the nozzle;

3.Performance indicators

4.The difference between the built-in spring and the external spring

An external spring that does not touch the contents and does not cause contamination of the contents due to spring embroidery.

The pump head is widely used in the cosmetics industry. It is used in the fields of skin care, toiletries and perfumes, such as shampoo, shower gel, lotion, serum, anti-milk, BB cream, liquid foundation, facial cleanser and hand sanitizer. And other product categories have applications.
