Abstract: An automatic fluid pump includes a pump body having a liquid channel and a mounting channel, the liquid channel having an inlet and an outlet and connected to a suction pipe and a delivery hose, respectively. A motor fan is disposed at a lower end of the suction pipe. A power controller is coupled to the pump body and circuit-connected to a battery, a terminal plate, and a switch. A valve case is coupled to the mounting channel in the form of a hopper formed at a lower end thereof with an inclined portion having an air hole. A valve case cap is coupled to the valve case. A main check valve is disposed on a lower surface of the valve case cap to open/close the through-holes. An auxiliary check valve is vertically moved up and down between the mounting channel and the air hole to open/close the air hole.

Abstract: A fluid pump includes a pump body with a manual operation bulb or a power supply unit provided on an upper end and an inlet and an outlet provided on both sides of a liquid passage. A suction pipe connected to the inlet of the pump body includes a bendable part between an upper suction pipe part and a lower suction pipe part which are formed in a rigid rod shape. A discharge hose shaped as a bellows tube is connected to the outlet of the pump body. A pipe sleeve has ends partially fitted into the upper suction pipe part and the lower suction pipe part. It is installed on the outer circumferential surface of the suction pipe and shaped as a cylinder or a “C” with one end cut out from the cylinder to facilitate moving its position from the bending part to the upper suction pipe part.
