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.
به طور کلی, the lotion pump is a simple and effective device for dispensing lotion, و به طور گسترده در صنایع آرایشی و بهداشتی و مراقبت شخصی استفاده می شود.
