On the other hand, the main body 200 is connected to the air discharge unit 300 or the air inlet 300 ', the cover 220 in the embodiment shown in Figure 1, the air discharge unit 300 or the air inlet 300' ) May be provided with a pollution prevention member 400. As shown in the illustrated embodiment, the air flow hole 410 may be formed in the pollution prevention member 400, and the filtering network 420 may be provided. Accordingly, it is possible to prevent the inflow of foreign matter into the air discharge unit 300 or the air inlet 300 'from the outside of the liquid storage tank 100. However, the contamination preventing member 400 is not limited to the illustrated embodiment, and may be made of only a filtration network, and the like. Anything that can prevent the ingress is possible.

3 to 7, the operation of one embodiment of the liquid storage tank 100 according to the present invention will be described in detail.

Body 200, inlet (I) and outlet (O) of the tank body 210 in the illustrated embodiment flow valve P with a valve (V) as shown in Figures 3, 5 and 7 ) May be connected.

When the valve V provided in the flow pipe P connected to the inlet port I and the outlet port O is closed, between the outside of the liquid storage tank 100 and the storage space S of the liquid storage tank 100. Since there is no pressure difference, only the elastic force by the elastic members 330 and 330 'acts on the guide members 340 and 340' of the air discharge part 300 and the air inlet part 300 '. Therefore, in this case, as shown in FIG. 2, the air flow holes 321 and 321 'of the cap members 320 and 320' are closed by the other side of the guide members 340 and 340 '.

In this state, as shown in FIG. 3, when the valve V provided in the flow pipe P connected to the inlet I is opened, the valve V provided in the flow pipe P connected to the outlet O is closed. As illustrated, liquid, for example, water, is introduced into the storage unit S of the main body 200 and the tank main body 210 in the illustrated embodiment through the inlet I.

When the liquid flows into the storage space S as described above, the pressure of the air present in the storage space S increases. Accordingly, a pressure difference is generated between the outside of the liquid storage tank 100 and the storage space S of the liquid storage tank 100. In addition, the force caused by the pressure difference acts on the guide member 340 in the direction opposite to the elastic force by the elastic member 330 acting on the guide member 340 of the air discharge unit 300.

When the inflow of the liquid into the storage space S through the inlet I continues, the force due to the pressure difference between the outside of the liquid storage tank 100 and the storage space S of the liquid storage tank 100 increases. As a result, the elastic force applied by the elastic member 330 is greater. Accordingly, as shown in FIG. 4, the guide member 340 of the air discharge unit 300 is moved, and the air flow hole 321 of the cap member 320 closed by the other side of the guide member 340 is moved. Will be opened. As a result, as shown in FIG. 4, the air present in the storage space S includes the air flow hole 321 of the cap member 320, the inside of the body 310, and the air flow hole 311 of the body 310. It is discharged to the outside of the liquid storage tank 100 through). Therefore, the inflow of the liquid into the storage space S through the inlet I can be made smoothly.

In addition, as shown in FIG. 5, the air flow holes 321 and 321 ′ of the cap members 320 and 320 ′ are closed by the other side of the guide members 340 and 340 ′ as shown in FIG. 2. When the valve V provided in the connected flow pipe P is closed, and the valve V provided in the flow pipe P connected to the outlet O is opened, the main body 200 as shown, in the illustrated embodiment Liquid, such as water stored in the storage space (S) of the tank body 210 flows out of the liquid storage tank 100 through the outlet (O).

As such, when liquid such as water stored in the storage space S flows out, the pressure of air existing in the storage space S is lowered. Accordingly, a pressure difference is generated between the outside of the liquid storage tank 100 and the storage space S of the liquid storage tank 100. And, the force caused by the pressure difference acts on the guide member 340 'in the direction opposite to the elastic force by the elastic member 330' acting on the guide member 340 'of the air inlet 300'. .

If the outflow of the liquid stored in the storage space S through the outlet O continues, the force due to the pressure difference between the outside of the liquid storage tank 100 and the storage space S of the liquid storage tank 100 increases. As a result, the elastic force applied by the elastic member 330 'is greater. Accordingly, as shown in FIG. 6, the guide member 340 ′ of the air inlet 300 ′ moves, and the air flow hole of the cap member 320 ′ closed by the other side of the guide member 340 ′. 321 'is opened. As a result, as shown in FIG. 6, the air outside the liquid storage tank 100 is discharged from the air flow hole 321 ′ of the cap member 320 ′ and the inside of the body 310 ′ and the body 310 ′. It is introduced into the storage space (S) of the liquid storage tank 100 through the air flow hole 311 ′. Therefore, the outflow of the liquid stored in the storage space S through the outlet O can be made smoothly.

As such, when the air outside the liquid storage tank 100 is introduced into the storage space S of the liquid storage tank 100 through the air inlet 300 ′, the outside air is shown in FIG. 5. As it passes through the filter net 420 of the pollution prevention member 400. Accordingly, the outside air is introduced into the storage space (S) of the liquid storage tank 100 through the air inlet 300 'in a state in which foreign matter contained therein is removed. Therefore, foreign matters can be prevented from entering the storage space S of the liquid storage tank 100.

As shown in FIG. 7, when both the valve V provided in the flow pipe P connected to the inlet I and the valve V provided in the flow pipe P connected to the outlet O are closed, as shown in FIG. There is no inflow of liquid into the storage space S of the liquid storage tank 100 or outflow of liquid from the storage space S of the liquid storage tank 100. Thus, the liquid remains in the storage space S. In this state, a pressure difference does not occur between the outside of the liquid storage tank 100 and the storage space S of the liquid storage tank 100. Accordingly, as shown in FIGS. 2 and 7, the other side of the guide member 340, 340 ′ of the air discharge part 300 and the air inlet part 300 ′ is formed by the elastic force of the elastic member 330, 300 ′. The air flow holes 321 and 321 'of the 320 and 320' are closed. Accordingly, the storage space S of the liquid storage tank 100 may be sealed. In addition, since the guide members 340 and 340 'are provided with the sealing members 341 and 341' as described above and shown, the sealing of the storage space S of the liquid storage tank 100 can be made more secure. As such, since the storage space S of the liquid storage tank 100 is sealed, foreign matter cannot enter the storage space S of the liquid storage tank 100 from the outside of the liquid storage tank 100.

Using the liquid storage tank 100 according to the present invention as described above, the inflow or outflow of liquid into the liquid storage tank 100 can be made smoothly.

It can also be closed when there is no inflow or outflow of liquid.

When there is no inflow or outflow of liquid, foreign matter may not flow into the liquid storage tank 100.

The liquid storage tank described above may not be limitedly applied to the configuration of the above-described embodiment, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications can be made. .
