A lotion pump works by creating a vacuum with a piston or diaphragm. The pump is made up of several components, including a dip tube, a piston or diaphragm, a valve, and a nozzle.
When you press the pump, the piston or diaphragm is pushed down, creating a vacuum that draws the lotion up through the dip tube. The valve then opens, allowing the lotion to flow out of the nozzle and onto the skin.
Per total, the lotion pump is a simple and effective device for dispensing lotion, și este utilizat pe scară largă în industria cosmetică și de îngrijire personală.
