Description

Bi-directional pumping machine for remaining liquid consumption

The present invention relates to a bidirectional pumping machine for consuming the remaining amount of liquid, and more particularly, when the container for storing the liquid is disposed in the forward direction and when the liquid is disposed in the reverse direction, the liquid can be discharged out of the container through the bidirectional pumping machine. It relates to a bidirectional pumping machine for consuming the remaining amount of liquid that can consume the remaining amount until the last.

In general, a fluid having a certain degree of viscosity, such as shampoo, conditioner, body wash, dish detergent, and cosmetics, is contained in a liquid container and distributed to the user. The liquid container includes a liquid container that is used by opening and closing the lid while being provided with a lid, and there is a liquid container that uses a screw pump to discharge the liquid inside the liquid container to the outside through the screw pump.

Since the liquid container using the screw type pumping machine has a difference in viscosity depending on the type of liquid, each has a different discharge pressure so that the liquid can be discharged from the container to the outside. . In addition, there is a difference in the height or capacity of the liquid container for each product, and most of the pumps are disposable.

In a liquid container using a conventional pumping machine, the length of the suction hose is formed differently depending on the height, and in order to discharge the liquid stored inside the liquid container as easily as possible, the liquid container is not completely in close contact with the bottom of the liquid container and is sucked at a small distance. Cut the end of the hose at an angle and install it.

However, the liquid container using such a conventional pumping machine has the following problems. As described above, the suction hose is spaced apart from the bottom of the container without being in close contact with the bottom of the liquid container in order to easily discharge the liquid stored in the liquid container.

Hereinafter, the operation method of the bidirectional pump for consuming the remaining amount of liquid according to another embodiment of the present invention described above will be described in detail.

When the container 310 is disposed in the forward direction, a process in which the liquid in the container 310 is discharged through the discharge part 411 will be described as follows. The user rotates the dial 325 so that the connection hole 323 provided in the lower portion of the chamber 322 of the cylinder 321 communicates with the suction pipe 331 as shown in FIG. 12( a ). (At this time, the space between the chamber 322 and the suction part 341 is blocked by the lower wall of the chamber 322 .)

Thereafter, when the user applies force to the head 410 , the pump 400 is pressed. As the pump unit 400 is pressed, the piston 421 coupled to the pump unit 400 slides downward in the chamber 322 to compress the chamber 322 .

(The upper part refers to the upward direction when the container 310 is disposed in the forward direction, and the lower part refers to the downward direction when the container 310 is disposed in the forward direction.)

At this time, the second bearing 342 is pushed to the outside by a compressive force generated while the space of the chamber 322 is compressed and blocks the space between the chamber 322 and the suction part 341 . (The second bearing 342 is in the form of a bead having a larger diameter than that of the suction part 341 , and can block the chamber 322 without being inserted into the suction part 341 .)

13 and 14, when the user removes the force pressing the head 410, the elastic restoring force of the spring 350 provided between the pump 400 and the body 320 is By this, the pump unit 400 slides upward, and the piston 421 coupled to the pump unit 400 also slides upward.

As the piston 421 slides upward, the space of the chamber 322 is relaxed and the second bearing 342 is lifted, thereby opening the inlet of the chamber 322 .

(At this time, the suction pipe-first bearing-chamber does not communicate.) There is an advantage that the remaining amount of liquid can be easily used through this.

In addition, the bidirectional pumping machine for consuming the remaining amount of liquid according to an embodiment of the present invention has the advantage of being able to use the liquid economically as the remaining amount of the liquid is consumed to the end, and environmental pollution by preventing the remaining amount of the liquid from being wasted has the effect of preventing
