The diaphragm pump 100, the reservoir 300 and the spray assembly 400 are all mounted on the body 200. The reservoir 300 may be used to store liquids such as water, medical fluids, nutritional fluids, and the like. The diaphragm pump 100 is in fluid communication with the tank 300 and the spray assembly 400 via tubing and is used to pump liquid from within the tank 300 to the spray assembly 400. The spray assembly 400 includes a spray head through which the spray assembly 400 sprays liquid for irrigation, disinsection, and the like.
Referring to fig. 2 and 3, a diaphragm pump 100 according to an embodiment of the present invention includes a pump body assembly 10, a motor assembly 20, and a liquid discharge assembly 30.
The pump body assembly 10 is formed with a liquid outlet 11. Specifically, the pump body assembly 10 includes a pump body 12, and a liquid inlet (not shown) is formed on the pump body 12.
