Description

Technical Field

[0001] The present application relates to the technical field of storage containers, and in particular to a piston-pressed beer storage tank. Background Art

[0002] At present, beer is a variety of foamy, cooked beers containing carbon dioxide that are brewed with barley malt as the main raw material, hops, and yeast fermentation. It is called "liquid bread"; beer is the best-selling low-alcohol beverage in countries around the world, and it is also one of the world's oldest and most widely used alcoholic beverages. There are many varieties, which can be classified according to the production method, product concentration, beer packaging container, and the type of yeast used for beer fermentation; beer needs to be stored and transported in storage tanks and needs to be stored isolated from air, otherwise it will easily spoil and cause waste.

[0003] However, existing beer storage cans have the following defects: after the storage can is opened, the beer needs to be consumed as soon as possible, otherwise it will quickly deteriorate and is difficult to store for a long time. If the beer is not finished, many people will choose to discard it, resulting in waste; in addition, when drinking, multiple cans are usually consumed, which takes up a lot of seat space. If placed on the ground, it is easy to be accidentally touched and tipped over, or even broken and damaged, making it inconvenient to use.

[0004] Therefore, how to design a piston-pressed beer storage tank to overcome the above-mentioned shortcomings is a problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] One purpose of the present application is to provide a piston-pressed beer storage tank that achieves long-term storage, avoids waste, occupies a small space, and is easy to use.

[0006] To achieve the above objectives, the technical solution adopted in the present application is: a piston-pressed beer storage tank, comprising a tank body, a cover body, a first piston assembly, a second piston assembly and a pressing assembly, the upper end of the tank body being an open structure, a first storage cavity being formed in the tank body; the cover body being detachably connected to the open portion of the tank body, a second storage cavity being formed in the cover body and communicating with the first storage cavity, and a discharge port being formed through the second storage cavity; the first piston assembly being movably disposed in the tank body and used for pushing the beer in the first storage cavity into the second storage cavity; the second piston assembly being movably disposed in the cover body and used for pushing the beer in the second storage cavity into the discharge port; the pressing assembly being disposed on the cover body and used for controlling the movement of the second piston to press out the beer.

[0007] Preferably, the lower end of the tank body is formed with an air hole; the first piston assembly includes a feed piston and a first one-way valve, the feed piston being disposed in the first storage chamber for vertical movement; the first one-way valve being disposed in the communication port between the first and second storage chambers, and being used to control the one-way flow of beer from the first storage chamber to the communication port. Advantageously, the movement of the feed piston, combined with the one-way control of the beer flow by the first one-way valve, propels the beer in the first storage chamber into the second storage chamber.

[0008] Preferably, the first one-way valve includes a first mounting seat, a first sealing plate, and a first elastic member. The first mounting seat is disposed within the communication port and has an annular structure. The first sealing plate is movably disposed on a side of the first mounting seat proximate to the second storage chamber. The first elastic member is disposed on the first mounting seat and is configured to force the first sealing plate to move until it seals against the inner ring of the first mounting seat. This advantageously controls the one-way flow of beer from the first storage chamber into the communication port.

[0009] Preferably, the second piston assembly includes a discharge piston and a second one-way valve. The discharge piston is vertically movable within the second storage chamber. The second one-way valve is disposed within the discharge port and is used to control the one-way flow of beer from the second storage chamber to the discharge port. Advantageously, the movement of the discharge piston, combined with the one-way control of the beer by the first one-way valve, propels the beer in the second storage chamber into the discharge port.

[0010] Preferably, the second one-way valve includes a second mounting seat, a second sealing plate, and a second elastic member. The second mounting seat is disposed within the discharge port and has an annular structure. The second sealing plate is movably disposed on a side of the second mounting seat away from the second storage chamber. The second elastic member is disposed on the second mounting seat and is configured to force the second sealing plate to move until it seals against the inner ring of the second mounting seat. This advantageously controls the one-way flow of beer from the second storage chamber to the discharge port.

[0011] As a preferred embodiment, the tank body includes a main body, a base, and a filter screen. The main body is a tubular structure. The base is detachably mounted on the lower end of the main body, and a support leg is provided at the lower end of the base. The air hole is formed on the base, and the filter screen is provided on the base and is used to filter the gas entering the air hole. This has the advantage that both the upper and lower ends of the tank body can be opened. When the first piston assembly moves to one end of the main body, beer can be added through the other end of the main body, avoiding the need to readjust the position of the first piston assembly after use. The base and the cover body are respectively connected to the upper and lower ends of the main body, making it easy to use. In addition, the support legs support the air hole to avoid interference with air intake. At the same time, the filter screen is used to prevent dust and debris from entering the main body and causing contamination.

[0012] Preferably, the pressing assembly includes a connecting rod, a pressing plate, and a reset member. The lower end of the connecting rod is connected to the second piston assembly, and the upper end extends outside the cover. The pressing plate is disposed at the upper end of the connecting rod. The reset member is disposed on the cover and is used to force the second piston assembly to reset as the connecting rod moves upward. This advantageously achieves both pressing and automatically reset the second piston assembly, making it easy to use.

[0013] Preferably, the reset member includes a reset rod and a third elastic member. The reset rod is disposed on the cover body so as to be movable up and down. The third elastic member is disposed on the cover body and is used to force the reset rod to move upward and abut against the pressing plate, thereby causing the reset rod to push the connecting rod upward and reset along with the pressing plate. This advantageously allows the reset member to force the second piston assembly to move upward and reset along with the connecting rod.

[0014] Preferably, the piston-pressed beer storage tank further comprises a discharge pipe disposed on the lid, one end of the discharge pipe being connected to the discharge port and the other end extending to the exterior of the lid. Advantageously, the discharge pipe extending to the exterior of the lid facilitates access to beer during use.

[0015] Compared with the prior art, the beneficial effects of the present application are as follows: when in use, the cover body and the tank body are disassembled, so that multiple cans of beer can be poured into the first storage chamber for unified storage, which takes up little space and is easy to use; then the cover body and the tank body are connected, and the pressing assembly cooperates with the second piston assembly to empty the air in the second storage chamber, and then the gas in the first storage chamber is sucked into the second storage chamber and then discharged, so that the first piston assembly can move upward to push the beer in the second storage chamber into the second storage chamber, avoiding the influence of the gas in the first storage chamber and the second storage chamber on long-term storage. When taking beer, the pressing assembly presses the second piston assembly to push the beer in the second storage chamber into the discharge port for taking out, and only as much as you drink is taken, avoiding waste. It can be seen from this that the piston-pressed beer storage tank achieves long-term storage, avoids waste, takes up little space, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Reference Figure 1-2One embodiment of the present application provides a piston-pressing beer storage tank, comprising a tank body 1, a cover body 2, a first piston assembly 3, a second piston assembly 4 and a pressing assembly 5. The upper end of the tank body 1 is an open structure, and a first storage chamber 11 is formed in the tank body 1; the cover body 2 is detachably connected to the open portion of the tank body 1, and a second storage chamber 21 communicating with the first storage chamber 11 is formed in the cover body 2, and a discharge port 22 is formed through the second storage chamber 21; the first piston assembly 3 is movably disposed in the tank body 1 and is used to push the beer in the first storage chamber 11 into the second storage chamber 21; the second piston assembly 4 is movably disposed in the cover body 2 and is used to push the beer in the second storage chamber 21 into the discharge port 22; the pressing assembly 5 is disposed on the cover body 2 and is used to control the movement of the second piston to press out the beer. During use, the cover 2 and the tank body 1 are disassembled, so that multiple cans of beer can be poured into the first storage chamber 11 for unified storage, which takes up little space and is easy to use. Then, the cover 2 and the tank body 1 are connected, and the pressing assembly 5 cooperates with the second piston assembly 4 to evacuate the air in the second storage chamber 21, and then the gas in the first storage chamber 11 is sucked into the second storage chamber 21 and then discharged. The first piston assembly 3 is able to move upward to push the beer in the second storage chamber 21 into the second storage chamber 21, avoiding the gas in the first storage chamber 11 and the second storage chamber 21 affecting long-term storage. When taking beer, the pressing assembly 5 presses the second piston assembly 4 to push the beer in the second storage chamber 21 into the discharge port 22 for taking out. You can take as much as you want to drink, avoiding waste. It can be seen from this that the piston-pressed beer storage tank can achieve long-term storage, avoid waste, take up little space, and be easy to use.

[0027] Reference Figure 2 as well as Figure 4-5 In some embodiments of the present application, an air hole 12 is formed at the lower end of the tank body 1; the first piston assembly 3 includes a feed piston 31 and a first one-way valve 32. The feed piston 31 is disposed in the first storage chamber 11 for vertical movement; the first one-way valve 32 is disposed in the communication port 23 between the first storage chamber 11 and the second storage chamber 21. The first one-way valve 32 is used to control the one-way flow of beer from the first storage chamber 11 to the communication port 23. The movement of the feed piston 31, coupled with the one-way flow control of the first one-way valve 32, promotes the beer in the first storage chamber 11 into the second storage chamber 21.

[0028] Reference Figure 5In some embodiments of the present application, the first one-way valve 32 includes a first mounting seat 321, a first sealing plate 322, and a first elastic member 323. The first mounting seat 321 is disposed within the communication port 23 and has an annular structure. The first sealing plate 322 is movably disposed on the first mounting seat 321, near the second storage chamber 21. The first elastic member 323 is disposed on the first mounting seat 321 and is used to force the first sealing plate 322 to move until it seals against the inner ring of the first mounting seat 321. This achieves controlled one-way flow of beer from the first storage chamber 11 into the communication port 23.

[0029] Reference Figure 2-3 In some embodiments of the present application, the second piston assembly 4 includes a discharge piston 41 and a second one-way valve 42. The discharge piston 41 is arranged in the second storage chamber 21 for vertical movement; the second one-way valve 42 is arranged in the discharge port 22, and the second one-way valve 42 is used to control the one-way flow of beer from the second storage chamber 21 to the discharge port 22. The movement of the discharge piston 41 is supplemented by the first one-way valve 32 to control the one-way flow of beer, thereby pushing the beer in the second storage chamber 21 into the discharge port 22. In addition, the outer annular surfaces of the feed piston 31 and the discharge piston 41 are provided with multiple sealing protrusions to improve the sealing and pushing effects.

[0030] Reference Figure 3-5 In some embodiments of the present application, the second one-way valve 42 includes a second mounting seat 421, a second sealing plate 422, and a second elastic member 423. The second mounting seat 421 is disposed within the discharge port 22 and has an annular structure. The second sealing plate 422 is movably disposed on the side of the second mounting seat 421 away from the second storage chamber 21. The second elastic member 423 is disposed on the second mounting seat 421 and is used to force the second sealing plate 422 to move until it seals against the inner ring of the second mounting seat 421. This achieves the goal of controlling the one-way flow of beer from the second storage chamber 21 to the discharge port 22.

[0031] During use, when the discharge piston 41 is pressed downward by the pressing assembly 5 to squeeze the beer in the second accommodating chamber, the second sealing plate 422 is forced to move away from the second mounting seat 421 and open, the second elastic member 423 is deformed, and the beer is able to enter the discharge port 22 until the beer in the second accommodating chamber is completely discharged, and the second elastic member 423 restores its deformation to force the second sealing plate 422 to close; when the second piston is forced to move upward by the pressing assembly 5, a negative pressure is formed in the second accommodating chamber, and the first sealing plate 322 is forced to move away from the first mounting seat 321 and open, the first elastic member 323 is deformed, and the beer in the first accommodating chamber is able to be sucked into the second accommodating chamber, and the feed piston 31 automatically moves upward until the pressure in the first accommodating chamber and the second accommodating chamber tends to be balanced, and the first elastic member 323 restores its deformation to force the first sealing plate 322 to close.

The air hole 12 is formed on the base 14, and the filter 15 is provided on the base 14 and is used to filter the gas entering the air hole 12. This allows the upper and lower ends of the tank body 1 to be opened. When the first piston assembly 3 moves to one end of the main body 13, beer is added through the other end of the main body 13, avoiding the need to readjust the position of the first piston assembly 3 after use. The base 14 and the cover body 2 are respectively connected to the upper and lower ends of the main body 13, which is convenient to use. In addition, the support leg 141 supports the air hole 12 to avoid interference with air intake. At the same time, the filter 15 is used to prevent dust and debris from entering the main body 13 and causing pollution.

[0033] It should be noted that the base 14 and the cover 2 and the body 13 are all detachably connected via threaded connections, which is a prior art and will not be described in detail here.
