[Structure] Rotor-blade pump 1 directly connected to electric motor 1
4, a flow path body 16 having liquid flow paths 11 and 12, a flow path switching valve fixing part 3, a flow path switching valve having a flow path switching valve movable part 5, a suction part 13 and a discharge part 6. .

Description

[Detailed Description of the Invention] The present invention is an act of injecting a liquid such as gasoline, kerosene, or water into a container such as a carrying plastic can (hereinafter referred to as the container) and discharging the liquid from the container. The present invention relates to a simple rotary-blade pump that has both functions and can be implemented without replacing the pump.

 The conventional rotary-blade type simple pump has only a function of discharging liquid, and it is very inconvenient because the set simple pump needs to be removed and replaced when injecting into the container.

 On the other hand, a simple pump with a flow path switching valve (hereinafter referred to as the pump) has a flow path switching valve attached to the flow path of a conventional simple pump in which the rotating blades rotate in a fixed direction. By changing the flow direction, it has both discharge and injection functions, and solves the above inconvenience.

 The operation and function of the rotary vane electric simple pump will be described below with reference to FIG. 1, which shows an example of a state in which a switching valve is incorporated in the flow path.

 First of all, when the liquid flow pipe 13 in the pump container is inserted into the container and the pump set by the container joint part 17 is used to inject a liquid from another container into the container, the flow path is switched. When the lever 10 is adjusted to the injection position 9, the electric motor is started, and the pump rotor 15 rotates at the inlet and outlet thereof in the direction of the arrow to always generate the liquid flow. The liquid sucked from the hose connected to the flow path switching valve moving part 5 passes through the flow path 12 and reaches the pump rotor blade 15. The liquid extruded from the liquid flow path switching valve again. It reaches the movable part 5, passes through the flow path 11, and is injected into the container through the liquid flow pipe 13 in the container.

In addition, when the injection is completed, the injection is stopped by switching the flow path switching lever 10 to the position of the stop position 8, and the air is introduced into the external hose connecting part 6 through the atmosphere intake port 4, and the liquid is The hose flows down and the movement of the liquid in the pump is stopped.

 Also, since the switch of the electric motor is linked to the operation of the switching valve, the electric motor also stops.

 Next, when the flow path switching lever 10 is switched to the discharge position 7, the electric motor is activated, and the liquid passes through the in-container flow tube 13 and the flow path of the flow path switching valve fixing portion 3, and then the flow path switching valve. By the flow path of the movable part 5, the liquid that has flowed into the pump rotor 15 through the flow path 12 is extruded from the flow path, passes through the flow path of the pump-side flow path body 16, and passes through the flow path 11. The liquid is discharged from the flow passage of the flow passage switching valve fixing portion 3 to another container through the flow passage of the flow passage switching valve fixing portion 5 and the hose connected to the external hose connecting portion 6.

 As described above, when the liquid is put into and taken out of the same container, it can be done only by switching the flow path switching valve.

Claims (1)

[Scope of utility model registration request] In the conventional rotary blade type electric and manual simple pumps, the only function is to discharge the liquid in the container in which the pump is installed to the outside, and the liquid is replenished in the container with the pump installed. I can't inject it. This school plan is to solve this problem, and it does not matter whether the pump is removed or installed, or the rotating direction of the rotor is changed.
This is done without significantly lowering the efficiency of the pump. By installing a valve that switches the flow path in one part of the flow path of the pump and changing the flow direction of the liquid, the discharge and injection can be performed. The action can be freely selected only by operating the flow path switching valve. Therefore,
It is characterized by incorporating and installing a flow path switching valve in a rotary vane type electric and manual simple pump to change the flow direction of the liquid by switching the flow path and to have both functions of discharge and injection. It is a simple pump with a flow path switching valve.
