The working principle of lotion pump head/daily chemical pump head

⒈ Pressing for the first time------When we press the pressing head for the first time, the pressing head passes through the connected main column and moves the auxiliary column to compress the spring together; in the process of compressing the spring, the outer wall of the piston collides with the inner cavity wall of the body, Promote the opening of the discharge hole of the sub-column by the piston; when the piston slides down, the air in the body is discharged through the discharge hole of the sub-column that has been opened;

 

⒉ Reciprocating pressing ------ all the air in the body is exhausted;

 

⒊Aspiration------Press the press head by hand to pass through the main column, sub-column, piston, and compress the tension spring together to discharge the air in the body, then release the press head, the tension spring will return (upper) due to loss of pressure. ) movement, at this moment, the piston also moves downward through the inner wall of the conflict body, closing the discharge hole of the sub-column; at this time, the liquid storage cavity in the body forms a vacuum suction state, sucking the glass ball upward, and passing the liquid in the bottle through the straw Suction the liquid into the body liquid storage cavity;

 

⒋Storage of liquid——Press the head several times, and after repeated suction, store the liquid to the body until the liquid storage is full;

⒌ Liquid discharge------When the liquid in the main body liquid storage chamber is full, press the press head again and the liquid will be sprayed directly from the press nozzle through the discharge hole.
