Introduction of the working principle of emulsion pump

Scope of application

The emulsion pump is suitable for: hand washing liquid, gel paste and so on. Each pump volume has 1.0CC and 2.0CC selections; only press 3-4 times to discharge liquid; left or right rotation can turn on or close the pump head, easy to use; seal design, leak proof; spring corrosion resistance is good; travel use this pump head product, convenient and save worry.

The working principle of emulsion pump

1. Pressing: when pressing the pressing head, the pressing head drives the auxiliary column to compress the spring together through the connected main column
2. Press repeatedly to exhaust all the air in the body;
3. Suction:press the pressing head by hand, pass through the main column, the auxiliary column and the piston, and compress the spring together to discharge the air in the body. Release the pressing head, and the spring moves back (up) due to the loss of pressure. At this time, the piston also moves down through the friction of the inner wall of the body to close the discharge hole of the auxiliary column; At this time, the liquid storage cavity in the body forms a vacuum suction state.
4. 4. Liquid discharge: when the liquid in the liquid storage chamber of the main body is full, press the pressing head again, and the liquid will be directly ejected from the pressing mouth through the discharge hole;
