Abstract

A foam soap dispenser capable of adjusting the amount of air includes a pump, a piston rod, a valve seat sheathed on the piston rod, a feed pipe coupled to the pump, a feed check valve for feeding a foam soap and a discharge check valve installed in the pump, an air-liquid mixing chamber formed between the feed check valve and the discharge check valve, an air-intake pipe communicated with an air-liquid mixing chamber, and an air-intake hole formed on the air-intake pipe that connects the air-liquid mixing chamber. The air-intake pipe includes an air-intake check valve, a screw sleeve and an air adjusting screw rod. The screw sleeve is fixed to the air-intake pipe, and the air adjusting screw rod is fixed into the screw sleeve and passed through a through hole of the screw rod of the check valve to insert the screw rod into the air-intake hole.
