Working principle of lotion pump

1. Press — press the head, press the head through the main column connected with the vice column together with compression spring, in the compression spring process, the Piston Wall through the inner wall friction with the body, forcing the Piston to open the vice column discharge hole; When the Piston slides down, the air in the body is discharged through the discharge hole of the sub-column which has been opened;

2. To and fro many times to press — press the air in the body completely;

3. Suction –press the head by hand through the main column, vice column, Piston, joint compression spring will be the body of the air out, loose head spring due to the loss of pressure, back(up) movement, at this time the Piston is also moving down through the friction of body wall, the discharge hole of the Auxiliary Column Is Closed; at this time, the liquid storage cavity in the body forms avacuum suction state, and the glass ball is sucked up, and the liquid in the bottle is sucked into the liquid storage cavity of the body through a suction pipe.

4. Storage of liquid — Press the head several times, and store the liquid to the body through several times of suction until the liquid is fully stored.
