Plastic Lotion Pump uses the principle of pressing liquid suction, which is to use the movement of the piston to discharge the air in the storage cylinder, resulting in internal and external air pressure so that the liquid rises under the action of air pressure and is discharged from the liquid outlet pipe to the outside of the pipe.
Some shampoo or body lotion pump heads will design a plastic buckle between the liquid outlet and the lower round cover at the beginning, which is used for fixing and preventing liquid leakage caused by the rotation of the pump head during transportation. . At this time, only after removing the plastic buckle, the pump head can be rotated. When the opened shampoo needs to be transported or moved, you can remove the pump head from the shampoo bottle, then press the pump head to the end, rotate the pump head in the opposite direction marked on the cap, and then screw the pump head back to the cap But this process requires a certain amount of effort. Finally, reinstall the pump head back into the bottle.
Design Advantages of Compression Pumps
1. In order to prevent liquid leakage due to mutual extrusion during transportation, this kind of pump head can only squeeze out the liquid after rotating the nozzle, which almost avoids the problem of liquid leakage.
2. It is convenient to control the amount used each time.
How to open the press head
1. Hold the nozzle part of the bottle with your hand and rotate the upper part of the pump head counterclockwise (looking from top to bottom).
2. Under normal circumstances, if you hear a "bang" sound, you will see the bottle mouth bounce. And the bottle mouth can be squeezed down and can be squeezed out, then the opening is successful, and the body lotion can be used.
3. If you find that it is getting tighter and tighter during the rotation, it means that the liquid storage bottle is designed with a reverse rotation switch. That is, you need to turn it clockwise to open, and when you hear a "bang" and see the mouth of the bottle pop up, you can press the top normally to squeeze out.
