Blow Head

Working Principle of Blow Head

The working principle of the pump head is the same as that of the piston pump. It also uses the movement of the piston and the opening of the single-phase valve to close and discharge the air in the liquid barrel to cause internal and external pressure rubbing, so that the liquid rises under atmospheric pressure and is discharged from the liquid outlet pipe. There is a push-type liquid suction mechanism in the hａnd sanitizer bottle, which is mainly composed of a catheter, a radial leaf ball valve, a yellow spring, a hollow plunger, a piston, a liquid outlet tube, and a barrel liquid. When the liquid is pressed down by hand, the pressure inside the barrel was large, the spring was compressed, and the leaf stem valve was closed. At the same time, because the piston moved downward, the liquid outlet hole on the hollow plunger was opened to remove the liquid. The liquid in the hole flows out of the liquid removal pipe from the liquid removal hole. When the hａnd is released, the yellow spring recovers, causing the piston to move upward and the pressure in the liquid removal barrel is reduced, and the liquid removal hole on the hollow plunger is closed. , The leaf stem valve is opened, and under the action of atmospheric pressure, the liquid enters the liquid removal bucket from the catheter through the leaf stem valve. In this way, the piston reciprocates up and down in the barrel and continuously sucks the liquid out of the bottle.

Product composition of Blow Head

The working principle of Blow Head

1. First press--------When we first press the press head, the press head drives the auxiliary column to compress the spring together through the connected main column; in the process of compressing the spring, the outer wall of the piston rubs against the inner cavity wall of the body. Prompt the piston to open the discharge hole of the auxiliary column; when the piston slides down, the air in the body is discharged through the discharge hole of the auxiliary column that has been opened;

2. Press repeatedly to and fro---exhaust all the air in the body;

3. Liquid suction-------Press the head by hａnd to pass the main column, sub-column, piston, and the common compression spring to expel the air in the body. Then loosen the head. The spring loses pressure and moves back (upper ) Movement. At this time, the piston also moves downward by rubbing 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, sucks the glass ball upwards, and passes the liquid in the bottle through The suction tube sucks the liquid into the liquid storage cavity of the body.

4. Store liquid ------Press the head several times, and store the liquid in the body through repeated suction until the liquid is full.

5. Liquid discharge-----------When the liquid in the body's liquid storage cavity is full, press the head again and the liquid will be sprayed directly from the nozzle through the discharge hole;
