Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like parts are designated with like reference numerals throughout the specification.

Next, a liquid injection device according to an embodiment of the present invention will be described with reference to FIG. 1.

1 is a schematic diagram schematically showing a liquid injection device according to an embodiment of the present invention.

Referring to FIG. 1, the liquid injection device 1 according to the present embodiment includes a reservoir 10, a water supply pipe 20, a liquid injection valve 40, and a pack air discharge valve 50.

The reservoir 10 includes a reservoir tank 110 and a partition wall 120 to which liquid to be injected into the liquid storage pack 60 flows. Liquids can be water, beverages, medications.

The storage space 111 is formed inside the storage tank 110. The partition wall 120 is disposed in the storage space 111. The storage space 111 in which the partition wall 120 is disposed includes a first space 111a and a second space 111b.

The lower side and both side surfaces of the partition wall 120 are connected to the inner circumferential surface of the reservoir space 111. However, the upper side of the partition wall 120 is separated from the inner circumferential surface of the partition wall 120. Accordingly, a passage 121 connecting the first space 111a and the second space 111b is formed at the upper side of the partition wall 120.

On one side of the upper surface of the reservoir tank 110 in which the first space 111a is located, a liquid injection port 112 is formed in which a liquid injection tube 130 connected to a water purification device (not shown) is coupled. The end of the liquid inlet tube 130 coupled to the liquid inlet 112 is close to the bottom surface 111c of the first space 111a.

On the other side of the upper surface of the reservoir tank 110 in which the second space 111b is located, an air outlet 113 communicating the second space 111b to the outside of the reservoir tank 110 is formed.

The air outlet 113 is provided with a pair of guides 113a facing each other. The upper side and the lower side of the pair of guides 113a are bent in a direction facing each other to form jaws 113b and 113c. The inner edge line of the jaw 113b located on the upper side of the guide 113a is chamfered.

In the air outlet 113, a liquid shutoff valve 30 that opens and closes the air outlet 113 is disposed. The liquid shutoff valve 30 is a buoyant body that can float in the liquid. The bottom of the liquid shutoff valve 30 may be seated in the lower jaw 113c. At this time, the bottom side of the lower jaw (113c) and the bottom of the liquid shutoff valve 30 may be formed such as irregularities or flow path groove (not shown). A gap through which air can pass between the lower side jaw 113c and the bottom face of the liquid shutoff valve 30 is generated by the unevenness or the flow path groove.

In addition, a gap is formed between the outer circumferential surface of the liquid shutoff valve 30 and the inner circumferential surface of the guide 113a to allow air to pass therethrough.

When the liquid shutoff valve 30 floats in the liquid, the upper surface of the liquid shutoff valve 30 may be in close contact with the upper jaw 113b. When the liquid is filled in the reservoir space 111, the liquid shutoff valve 30 blocks the air outlet 113 so that the liquid in the reservoir space 111 does not leak through the air outlet 113.

On the other hand, the projection 31 is formed in the upper surface of the liquid shutoff valve 30, and the edge line of the projection 31 is chamfered. The chamfered portion of the projection 31 is in close contact with the chamfered portion of the upper jaw 113b to maintain airtightness. In addition, a packing (not shown) may be installed in the chamfer portion of the protrusion 31 and the chamfer portion of the upper side jaw 113b to further improve airtightness.

The liquid discharge port 114 to which the upper side of the water supply pipe 20 is coupled is formed at the bottom surface of the second space 111b facing the air discharge port 113.

The liquid storage pack 60 is connected to the lower side of the water supply pipe 20. The liquid storage pack 60 includes a pack body 61, a connection portion 62 having a flow path, and a stopper (not shown) disposed inside the pack body 61 to open and close the flow path. The stopper is connected to the connecting portion 62 by an elastic member (not shown). Accordingly, the plug blocks the flow path by the elastic force of the elastic member.

Thereby, the lower side of the water supply pipe 20 is connected to the flow path of the connection part 62, and can press a stopper. The stopper pressurized by the water supply pipe 20 may open the inside of the pack body 61 to fall from the flow path.

On the other hand, the water supply pipe 20 is formed in a telescopic, bellows manner may be adjustable in length.

The liquid injection valve 40 is attached to the water supply pipe 20. The liquid injection valve 40 may be connected to the solela to open and close the inside of the water supply pipe 20. When the liquid injection valve 40 is opened, the inside of the pack body 61 may be connected to the second space 111b.

The pack air discharge valve 50 is located between the liquid storage pack 60 and the liquid injection valve 40 and connected to the water supply pipe 20. That is, the pack air discharge valve 50 is connected to the lower end of the water supply pipe 20 by a pipeline 51. The pack air outlet valve 50 is connected to the solede. The pack air discharge valve 50 is opened only when the liquid injection valve 40 is closed.

Next, the operation of the liquid injection device 1 from above will be described with reference to FIGS. 2 to 5.

FIG. 2 is a schematic view showing a state in which liquid is accommodated in the water storage body of the liquid injection device 1 shown in FIG. 1 of the present invention, and FIG. 3 shows a state in which the liquid shutoff valve shown in FIG. 2 is blocking the air outlet port. 4 is a schematic view showing a state in which a liquid storage pack is expanded by injecting liquid into the liquid storage pack shown in FIG. 3, and FIG. 5 is a view showing that the air inside the liquid storage pack shown in FIG. Schematic diagram showing the state discharged to.

First, referring to FIG. 2, the lower end portion of the water supply pipe 20 couples the connection portion 62 of the liquid storage pack 60. When the water supply pipe 20 is coupled to the connecting portion 62, the plug is in a state away from the flow path. The lower end of the water supply pipe 20 is located inside the pack body 61 of the storage pack 60.

In this state, in the state in which the liquid injection valve 40 and the pack air discharge valve 50 are closed, the purified water may flow into the first space 111a through the liquid injection pipe 130.

The liquid introduced into the first space 111a is filled in the first space 111a. In this case, the liquid filled in the first space 111a may overflow into the second space 111b through the passage 121.

At this time, the bottom of the liquid shut-off valve 30 maintains the state in close contact with the lower side jaw (113c). When the liquid flows into the first space 111a and the second space 111b, the air in the first space 111a and the second space 111b is lower than the lower jaw 113c and the liquid shutoff valve 30. Pass through the gap between the bottom of the air outlet 113 may be discharged to the outside.

The liquid introduced into the second space 111b flows into the water supply pipe 20 and reaches the position of the liquid injection valve 40.

Next, referring to FIG. 3, when the liquid is filled in the first space 111a and the second space 111b, the liquid is attracted to the passage 121. At this time, the liquid shutoff valve 30 positioned at the air outlet 113 is suspended by the liquid. The upper surface of the floating liquid shutoff valve 30 is in close contact with the upper jaw 113b. As the upper surface of the liquid shutoff valve 30 is in close contact with the upper jaw 113b, the liquid introduced into the first space 111a and the second space 111b flows out of the reservoir tank 110 through the air outlet 113. It is not discharged.

Next, referring to FIG. 4, when the liquid is filled in the first space 111a and the second space 111b, the liquid injection valve 40 is opened to open the inside of the pack body 61 and the second space 111b. Connect.

When the inside of the second space 111b and the pack body 61 are connected, the liquid in the second space 111b naturally flows into the pack body 61 through the water supply pipe 20. At this time, the water supply pipe 20 is coupled to the bottom surface of the second space 111b so that only pure liquid may flow into the pack body 61.

When the liquid flows into the pack body 61, the pack body 61 expands as much as the incoming liquid. When the liquid is filled in the pack body 61, the liquid injection valve 40 is closed to prevent the liquid of the second space 111b from flowing into the pack body 61 any more. At this time, the air inside the pack body 61 may remain inside the pack body 61.

On the other hand, the liquid shutoff valve 30 can not be suspended because the amount of the liquid in the second space (111b) is reduced. As a result, the liquid shutoff valve 30 is lowered and the bottom face is in close contact with the lower jaw 113c.

Next, referring to FIG. 5, the pack air discharge valve 50 is opened while the liquid injection valve 40 is closed. When the pack air discharge valve 50 is opened, the inside of the pack body 61 is connected to the outside, and at the same time, the pack body 61 expanded by the liquid injection is contracted. Air and liquid in the pack body 61 may be discharged to the outside of the pack body 61 through the conduit 51 by the contracting action of the pack body 61. When the air inside the pack body 61 is discharged due to the contraction of the pack body 61, the pack air discharge valve 50 is closed to prevent the liquid introduced into the pack body 61 from being discharged.

On the other hand, it is possible to pressurize the pack body 61 by increasing the length of the water supply pipe 20 so that the air in the pack body 61 can be smoothly discharged.

When the water supply pipe 20 is detached from the connecting portion 62 in this state, the plug stops the flow path of the connecting portion 62 by the elastic force of the elastic member. As the stopper blocks the stopper of the connecting portion 62, the fluid introduced into the pack body 61 is no longer discharged to the outside.

As such, only the pure liquid is stored in the pack body 61 and air is not introduced, thereby preventing deterioration of the liquid by the air.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided.
