PURPOSE: A liquid detergent supply pump is provided to block the inflow if a liquid detergent into an air supply unit, and to miniaturize the size of the pump. CONSTITUTION: A liquid detergent supply pump includes a body unit(110), an air supply unit(120), a driving motor(130), a link member(140), and a pressure chamber(150). The body unit includes a space in the predetermined size. The air supply unit is located inside the body unit, and includes an internal space for moving a piston with a packing on one side. An air transfer pipe is extended from the air supply unit for transferring air compressed and expanded by the movement of the piston. A rotary shaft, which is inserted into a rotary shaft insertion groove on the body unit, is located on the same axis of the air transfer pipe on the lower side of the air supply unit. The driving motor is rotates the rotary shaft by driving force. The link member includes a rotary shaft coupling groove, and a piston coupling groove. The pressure chamber is located on the upper side of the piston and connected to the internal space of the air supply unit, and includes an inlet valve(151e) and an outlet valve(152d) for inserting and discharging a liquid detergent. |
