Plastic Lotion Pump Suppliers introduces that the press pump head uses the principle of press suction, which uses the movement of the piston to discharge the air existing in the storage cylinder, causing internal and external air pressure, so that the liquid rises under the action of the air pressure, from the liquid outlet pipe Exhaust to the outside of the tube.
In the beginning, the breast pump head will be designed with a plastic buckle between the liquid outlet and the lower ground cover, which is used for fixing and preventing the pump head from rotating and leaking during transportation. At this time, you only need to remove the plastic buckle and then rotate the pump head. When the opened pump head bottle needs to be transported or moved far away, 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 as indicated on the cap, and then re-twist the pump head Go back to the lid, but this process requires a certain amount of effort. Finally, reinstall the pump head back to the bottle.
Design advantages of the press pump:
1. In order to prevent liquid leakage due to mutual squeezing 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. Convenient to control the dosage for each use.
