On the contrary, the invention is described in connection with the embodiments for the purpose of covering alternatives or modifications that may be extended based on the claims of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be practiced without these particulars. Moreover, some of the specific details have been left out of the description in order to avoid obscuring or obscuring the focus of the present invention. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1 to 3, the present invention provides a liquid storage device 1 including: the inner cavity of the shell 10 is provided with a breathable and waterproof membrane 20, the breathable and waterproof membrane 20 is arranged facing to the air vent 11 of the shell 10, and the breathable and waterproof membrane 20 divides the inner cavity of the shell 10 into a liquid storage cavity 13 and a valve cavity 12; wherein, be equipped with first moving part 30 in the valve chamber 12, first moving part 30 can move towards the vent 11 in the valve chamber 12 and block up vent 11, can reduce the risk that the tobacco juice in the stock solution chamber 13 leaks by vent 11 like this.
Wherein the air-permeable and water-impermeable membrane 20 is capable of preventing liquid from permeating from one side of the membrane to the other while maintaining the free two-way permeability of gas. I.e. to prevent liquid from penetrating from the reservoir chamber 13 to the valve chamber 12. The air-permeable and water-impermeable membrane 20 is composed of two or more layers and can be made of polymer film materials such as PTFE, ePTFE, etc. In this embodiment, the thickness of the air-permeable and water-impermeable film 20 is not more than 5 mm.
Specifically, in a first pressure state (e.g., in an atmospheric pressure state), the external air pressure P1 of the enclosure 10 is equal to the internal air pressure P2 of the enclosure 10; that is, the air pressure of the external environment where the liquid storage device 1 is located is P1, and the air pressure of the inner cavity of the liquid storage device 1 is P2. Referring to FIG. 4, in the first pressure state, the acting force of the external air pressure P1 on the first movable member 30 is F1, the acting force of the internal air pressure P2 on the first movable member 30 is F2, and the gravity of the first movable member 30 is M1, wherein M1+ F1 is greater than or equal to F2.
The first movable member 30 is in a free state under the action of gravity in the valve cavity 12, the first movable member 30 does not block the vent 11, and the vent 11 is in a normally open state. The vent 11 can keep the internal air pressure of the inner cavity of the shell 10 equal to the external air pressure, and the liquid in the liquid storage cavity 13 can flow out normally and is not influenced by negative pressure.
In a second pressure state (e.g., in an ambient state of high altitude airplane travel, low temperature, etc.): the external air pressure P1 of the housing 10 is less than the internal air pressure P2 of the housing 10, the acting force of the external air pressure P1 on the first movable member 30 is F1, the acting force of the internal air pressure P2 on the first movable member 30 is F2, the gravity of the first movable member 30 is M1, wherein M1+ F1 < F2.
At this time, the first movable member 30 moves toward the vent 11 in the valve cavity 12 under the action of the air pressure to block the vent 11 (the direction B in fig. 3 shows the moving direction of the first movable member 30), and a compression sealing action is generated on the vent 11. The internal air pressure will be kept in equilibrium in this state, and will be kept stable while sealing the vent 11. The atmospheric pressure that inside liquid received can not last rising, and restriction stock solution chamber 13 internal gas lasts the inflation, reduces the outside risk of inflated gas with liquid extrusion stock solution device 1.
After the liquid storage device 1 is used for a period of time, the liquid in the liquid storage cavity 13 is reduced, the liquid level of the liquid storage cavity 13 is reduced, and a cavity is formed and is positioned between the air-permeable and water-impermeable film 20 and the liquid level of the liquid storage cavity 13. In the second pressure state, the valve chamber 12 and the gas in the chamber are continuously expanded, and the first movable member 30 moves towards the vent 11 in the valve chamber 12 to block the vent 11; even if the sealing connection between the air-permeable and water-impermeable membrane 20 and the inner wall of the housing 10 is affected, after the gap is generated, the liquid in the liquid storage cavity 13 flows out from the gap, because the vent 11 is blocked, thereby reducing the risk that the liquid is squeezed out of the outside of the liquid storage device 1.
The shape of the first movable element 30 of the present invention is not limited, and the vent hole 11 may be closed. Referring to fig. 2 and 3, in the present embodiment, the first moveable member 30 is spherical.

The diameter of the spherical first movable part 30 is not less than 0.2mm and not more than 10mm, the minimum size position of the irregular body is not less than 0.2mm, and the maximum size position is not more than 10 mm; this arrangement allows the first movable member 30 to block the vent opening 11.
In addition, in the present embodiment, the first movable member 30 is elastically contacted with the air vent 11. Thus, the sealing effect can be maintained in a pressurized state, and the risk of liquid leaking out through the vent 11 can be further reduced. The first movable member 30 is made of an elastic material. At least the portion of the first movable member 30 contacting the vent 11 is made of an elastic material, such as a silicone material. The spherical first movable part 30 is an air-impermeable liquid-impermeable sphere with an elastic outer surface, which is formed by compounding one or more materials with silica gel thickness not less than 10% of the radius of the sphere from the outer surface to the center of the sphere.
