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.
當你按泵時, 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.
整體, the lotion pump is a simple and effective device for dispensing lotion, 廣泛應用於化妝品和個人護理行業.
