Description

Technical Field

[0001] The invention belongs to the technical field of wine drinking equipment and relates to a wine barrel. Background Art

[0002] A beer barrel is a container for holding beer or other alcoholic beverages. Traditional barrels typically contain high-pressure gas to draw out the beer, forcing the beer to flow out through a dispensing valve under high pressure. For example, a patent document discloses a container for storing and dispensing beverages, particularly beer (Application No. 99814464.9). A pressure device is installed within the container's interior to provide pressure for dispensing the beer. The container comprises a cylindrical wall, a bottom, and a top surface. A valve is provided on the top surface. The valve includes an outer shell, a spring, and a valve body within the outer shell. When the valve body overcomes the spring pressure and moves downward, the beer dispensing channel within the outer shell is connected. A vertical tube extends from the lower end of the outer shell, extending to the bottom of the container's interior. During actual use, the barrel has some shortcomings: when dispensing beer, the beer flows upward along the vertical pipe under pressure. After the beer flows out of the vertical pipe, it will still maintain a relatively fast flow rate and impact the spring and valve body in the outer shell. At this time, the beer will be restricted and obstructed by the spring and valve body, causing the gas and liquid in the beer to separate and form foam, which in turn leads to a decrease in the quality of the beer and affects the drinking taste of the beer.

[0003] At present, in order to improve the quality of beer when it flows out of the barrel, the conventional technical solutions are:

[0004] 1. Reasonably control the beer dispensing pressure to avoid excessive beer flow through pressure control, so that the beer can flow out of the beer valve smoothly, reduce foam and improve the quality of the beer.

[0005] 2. Improve the beer dispensing effect by improving the structure of the beer dispensing valve, such as the faucet. Usually, a pressure reducer or regulating valve is installed at the outlet of the faucet to control the flow rate and pressure of the beer, thereby reducing the generation of foam. In addition, the material of the beer faucet can also affect the generation of foam. Therefore, those skilled in the art usually use stainless steel or plastic beer faucets to reduce the generation of foam.

[0006] 3. Temperature control: The temperature of beer affects the production of foam. Normally, the temperature of beer should be controlled between 5-8°C. If the temperature is too high, foam will be easily produced, while if the temperature is too low, the foam will become denser. Summary of the Invention

[0007] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a wine barrel. The present invention solves the problem that the quality of beer produced by the existing wine barrel is not high, which affects the taste of beer.

[0008] The objectives of the present invention can be achieved through the following technical solutions: a wine barrel, comprising a barrel body, a gas cylinder is provided in the barrel body and a bottle mouth is provided on the top of the gas cylinder, characterized in that a wine inlet hole is provided on the outer wall of the bottle mouth, a wine outlet cavity is provided in the bottle mouth, and a valve core assembly that can open or cut off the wine outlet cavity is provided in the wine outlet cavity, the bottle mouth also has an annular buffer cavity arranged around the outer periphery of the wine outlet cavity and a wine outlet connecting the wine outlet cavity and the annular buffer cavity, and the wine inlet hole is connected to the annular buffer cavity.

[0009] When the wine barrel is in use, a wine guide tube is first connected to the wine inlet so that beer can be introduced into the wine inlet through the wine guide tube. At this time, since there is also an annular buffer chamber in the bottle mouth, and the wine outlet channel and the annular buffer chamber are connected through the wine outlet, this arrangement allows most of the beer flowing out of the wine inlet to first enter the annular buffer chamber, and then flow into the wine outlet channel through the wine outlet, and finally flow out of the wine outlet channel for people to drink.

[0010] Obviously, the design of this beer barrel ensures that after the beer flows out of the beer outlet, most of the beer first enters the annular buffer chamber instead of directly flowing into the beer outlet channel. Since the annular buffer chamber is annular and arranged around the outer circumference of the beer outlet channel, the beer will be decelerated and buffered after entering the annular buffer chamber, and a regular circumferential flow will be formed. The flow process is relatively smooth. In this way, more beer enters the beer outlet channel after being decelerated and buffered by the annular buffer chamber. Therefore, the impact on the valve core assembly can be greatly reduced, and the foam can be effectively reduced to improve the quality of the beer, thereby improving the drinking taste of the beer.

[0011] In the above-mentioned beer barrel, the bottle mouth portion includes a bottle mouth body and a joint covering the upper side of the bottle mouth body. The joint includes a vertically arranged and cylindrical beer outlet portion and a disc portion integrally formed at the lower end of the beer outlet portion. The interior of the beer outlet portion forms the beer outlet channel, and the annular buffer chamber is formed between the disc portion and the top of the bottle mouth body. In this structure, the bottle mouth body and the joint can be manufactured separately and then assembled to form the annular buffer chamber. This manufacturing method facilitates the processing of the annular buffer chamber and ensures a smooth surface of the annular buffer chamber, making the beer flow more smoothly in the annular buffer chamber, thereby reducing foam and improving the quality of beer.

[0012] In the above-mentioned beer barrel, the top of the bottle mouth body has a top plate portion with an annular retaining edge 1 on its edge, the middle portion of the lower side surface of the circular disc portion has an annular raised portion, and the edge of the circular disc portion has an annular retaining edge 2. The annular retaining edge 1 abuts against the annular retaining edge 2 and forms a seal therebetween. An annular groove is formed between the annular retaining edge 2 and the raised portion, and the annular buffer chamber is formed between the annular groove and the upper side surface of the bottle mouth body. By providing an annular groove between the raised portion and the annular retaining edge 2 on the circular disc portion, the cross-sectional size of the annular buffer chamber can be increased. When the size of the bottle mouth of the gas cylinder is limited, the space of the annular buffer chamber can be increased as much as possible, thereby better buffering the beer and improving the quality of the beer. By the abutment between the annular retaining edge 2 and the annular retaining edge 1, a better sealing effect can be achieved between the two, thereby preventing beer leakage.

[0013] In the aforementioned wine barrel, the raised portion is provided with a wine-passing notch, with both ends penetrating the sidewall of the wine outlet and the sidewall of the annular groove. The wine-passing opening is formed between the wine-passing notch and the upper side surface of the top plate. This design not only facilitates the processing of the wine-passing opening, but also allows the beer to flow along the upper side surface of the top plate as it passes from the annular buffer chamber through the wine-passing opening into the wine-discharging channel. This prevents the beer from flowing in an uneven manner, allowing the beer to flow more smoothly into the wine-discharging channel, thereby reducing the generation of foam and improving the quality of the beer.

[0014] In the above-mentioned wine barrel, the middle part of the top plate part has a cylindrical wine guide part, and the wine guide part is inserted into the wine outlet part. The wine guide part is provided with a strip notch arranged along its axial direction, and the strip notch is arranged opposite to the wine outlet. The design of the wine guide part is that on the one hand, since it is inserted into the wine outlet part, the relative positions of the bottle mouth body and the joint can be radially positioned through the plug-in cooperation of the two, thereby improving the connection stability of the bottle mouth body and the joint. In addition, after the beer enters the strip notch from the wine outlet, it enters the wine guide part. At this time, the wine guide part guides the flow of beer, so that the beer can only flow out of the wine outlet cavity upwards, and will no longer flow out into the annular buffer cavity. In this way, the beer flow process is more orderly and smooth, so that the quality of the beer can be improved. For the convenience of processing, the upper end of the strip notch passes through the upper end face of the wine guide part.

[0015] In the aforementioned wine barrel, a wine bag is disposed within the barrel body. The bag opening sealing sleeve is disposed on the upper side of the disc portion. The gas cylinder has a gas storage cavity. The mouthpiece body is provided with an exhaust passage communicating with the gas cylinder's gas storage cavity. The raised portion is provided with a recessed opening, and a venting nozzle integrally formed with the raised portion is disposed within the recessed opening. The top plate portion is provided with a socket portion on the upper side communicating with the exhaust passage. The venting nozzle is inserted into the socket portion and forms a seal with the inner wall of the socket portion. When the pressure within the barrel decreases, the gas cylinder releases gas, which then passes through the exhaust passage and the venting nozzle and enters the barrel body, thereby increasing the pressure within the barrel body to meet the required pressure for discharging the beer. This pressure compresses the wine bag to discharge the beer. In this wine barrel, the combination of the mouthpiece body and the joint not only enables discharging the beer but also exhausts the gas, effectively achieving gas-liquid separation. Gas released from the gas cylinder acts on the outer wall of the wine bag to discharge the beer, rather than on the surface of the beer liquid. Therefore, the gas does not come into contact with the beer, preventing contamination of the beer and improving the beer's drinking experience.

[0016] In the aforementioned wine barrel, the raised portion is provided with a positioning notch having two parallel limiting sidewalls. The top plate portion has two parallel positioning ridges on its upper side. Both positioning ridges are located within the positioning notch and engage with the two limiting sidewalls of the positioning notch. This design allows the joint to be positioned circumferentially relative to the bottle mouth body. During assembly or use of the wine barrel, the positioning ridges limit the joint's rotation, thereby protecting the exhaust nozzle. Because the exhaust nozzle is a relatively small plastic part, protecting the exhaust nozzle effectively prevents deformation or even tearing, thereby ensuring the service life of the wine barrel and the stability of wine discharge.

[0017] In the above-mentioned wine barrel, the wine inlet is located directly below the annular groove and is vertically arranged. A wine outlet joint is provided in the wine inlet, and the upper end of the wine outlet joint is embedded in the wine outlet on the side close to the wine outlet, and the upper end face of the wine outlet joint is close to the upper side face of the wine outlet. The wine inlet is located directly below the annular groove and is vertically arranged, so that when the beer flows out of the wine outlet, it still maintains an upward flow trend so that most of the beer enters the annular groove, and because the upper end of the wine outlet joint is embedded in the wine outlet on the side close to the wine outlet, and the upper end face of the wine outlet joint is close to the upper side face of the wine outlet with only a small gap left, when the beer flows out of the wine outlet, most of the beer will not directly enter the wine outlet cavity, but will flow upward into the annular concave cavity. After that, these beers are buffered in the annular buffer cavity before entering the wine outlet cavity. This can better reduce the impact of beer on the valve core assembly, thereby reducing foam, making the beer discharging effect better and improving the drinking taste of beer. In addition, the wine inlet and the wine outlet are arranged adjacent to each other, so that the upper end of the wine outlet joint is embedded in the wine outlet on the side close to the wine outlet. In this way, the space of the wine outlet is effectively utilized. When the size of the bottle mouth is limited, the diameter of the wine inlet and the wine outlet joint can be made as large as possible, thereby making the wine barrel have a larger wine outlet flow rate. At the same time, the flow rate of beer in the wine inlet can be reduced, thereby reducing the generation of foam.

[0018] In the aforementioned wine barrel, the wine bag is further provided with a wine guide tube. The upper end of the wine outlet connector is threadedly connected to the inner wall of the wine inlet. The upper end of the wine guide tube is sleeved onto the wine outlet connector, and the lower end of the wine guide tube extends to the bottom of the wine bag. The provision of the wine guide tube allows the beer in the wine bag to flow upward along the wine guide tube, thereby facilitating the beer's exit from the wine bag and preventing beer residue in the wine bag. The wine outlet connector is threadedly connected to the inner wall of the wine inlet, making it easier to install. Furthermore, the provision of the wine outlet connector facilitates installation of the wine guide tube.

[0019] In the aforementioned wine barrel, a bushing is inserted into the barrel opening of the barrel body. The bushing has a vertically arranged wine outlet in the middle. The wine outlet extends from the lower end of the wine outlet into the wine outlet, and the wine outlet is snap-connected to the side wall of the wine outlet. When installing a gas cylinder, simply insert the joint at the mouth of the gas cylinder into the bushing, so that the wine outlet on the joint snaps into the side wall of the wine outlet, and the gas cylinder is installed, which is very convenient.

[0020] Compared with the existing technology, this wine barrel has the following advantages:

[0021] 1. The design of this beer barrel ensures that after the beer flows out of the beer outlet, most of the beer first enters the annular buffer chamber instead of directly flowing into the beer outlet channel. Since the annular buffer chamber is annular and arranged around the outer circumference of the beer outlet channel, the beer will be decelerated and buffered after entering the annular buffer chamber to form a regular circumferential flow, and the flow process is relatively smooth. In this way, most of the beer enters the beer outlet channel after being decelerated and buffered by the annular buffer chamber, thereby greatly reducing the impact on the valve core assembly, effectively reducing foam, making the beer outlet quality good, and thus improving the drinking taste of the beer.

[0022] 2. In this beer barrel, the gas released by the gas cylinder acts on the outer wall of the beer bag to realize beer discharge, rather than acting on the surface of the beer liquid. Therefore, the gas will not come into contact with the beer, which can prevent the beer from being contaminated by the gas and thus improve the drinking taste of the beer.

DETAILED DESCRIPTION

[0033] The following is a specific embodiment of the present invention and combined with the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to this embodiment.

[0034] like Figure 1 and Figure 2 As shown, the wine barrel includes a barrel body 1, a gas cylinder 2 is provided in the barrel body 1 and the top of the gas cylinder 2 is provided with a bottle mouth 3, the outer wall of the bottle mouth 3 is provided with a wine inlet hole 311, the bottle mouth 3 has a wine outlet cavity 321 and the wine outlet cavity 321 is provided with a valve core assembly 4 which can open or cut off the wine outlet cavity 321, the bottle mouth 3 also has an annular buffer cavity 35 arranged around the outer periphery of the wine outlet cavity 321 and a wine passing port 34 connecting the wine outlet cavity 321 and the annular buffer cavity 35, and the wine inlet hole 311 is connected with the annular buffer cavity 35.

[0035] Specifically, such as Figure 2 and Figure 3 As shown, the bottle mouth portion 3 includes a bottle mouth body 31 and a joint 32 covered on the upper side of the bottle mouth body 31. A compression cap 33 is also threadedly connected to the bottle mouth body 31. The compression cap 33 can press the joint 32 downward to fix the joint 32 and the bottle mouth body 31 to each other. A wine bag 5 is provided in the barrel body 1. The bag opening sealing sleeve of the wine bag 5 is provided on the upper side of the disc portion 323. The gas cylinder 2 has a gas storage cavity 21. The bottle mouth body 31 is provided with an exhaust channel 316 that can communicate with the gas storage cavity 21 of the gas cylinder 2. Figure 1 As shown, the lower end of the bottle mouth body 31 is threadedly connected to the bottom cover 13, and the bottom cover 13 can support the inner liner of the gas cylinder 2 upward, and the inner liner of the gas cylinder 2 forms the gas storage chamber 21 of the gas cylinder 2.

[0036] Combine Figure 3 and Figure 4As shown, the joint 32 includes a vertically arranged and cylindrical wine outlet 322 and a disc portion 323 integrally formed at the lower end of the wine outlet 322. The interior of the wine outlet 322 forms a wine outlet channel 321, and an annular buffer chamber 35 is formed between the disc portion 323 and the top of the bottle mouth body 31. Figure 2 As shown, a bushing 8 is inserted into the barrel mouth of the barrel body 1. The middle part of the bushing 8 has a vertically arranged wine outlet 81. The wine outlet portion 322 extends from the lower end of the wine outlet 81 into the wine outlet 81, and the wine outlet portion 322 is connected to the side wall of the wine outlet 81 by snapping. The valve core assembly 4 includes a valve core 41 and a spring 42. Under the action of the spring 42, the valve core 41 can remain in a state of blocking the wine outlet channel 321. When the wine outlet pipe is inserted into the upper end of the wine outlet 81, the wine outlet pipe can press the valve core 41 downward, thereby opening the wine outlet channel 321. At this time, the beer in the wine outlet channel 321 can flow out through the wine outlet pipe for people to drink. The wine outlet pipe is a prior art and is not shown in the drawings.

[0037] like Figure 3 、 Figure 4 and Figure 5 As shown, the top of the bottle mouth body 31 has a top plate portion 313 with an annular retaining edge 1 312 on its edge. The middle portion of the lower side of the circular disc portion 323 has an annular raised portion 324. The edge of the circular disc portion 323 has an annular retaining edge 2 325. The annular retaining edge 1 312 abuts against the annular retaining edge 2 325, with a sealing ring provided between the two to form a seal. An annular groove 3210 is formed between the annular retaining edge 2 325 and the raised portion 324. An annular buffer chamber 35 is formed between the annular groove 3210 and the upper side of the bottle mouth body 31. The annular groove 3210 formed between the raised portion 324 and the annular retaining edge 2 325 on the circular disc portion 323 increases the cross-sectional size of the annular buffer chamber 35. Given the limited size of the bottle mouth 3 of the gas cylinder 2, the space in the annular buffer chamber 35 can be maximized, thereby better buffering the beer and improving the beer quality.

[0038] like Figure 2 and Figure 3As shown, the wine inlet hole 311 is located directly below the annular groove 3210 and is arranged vertically. A wine outlet joint 6 is provided in the wine inlet hole 311. The upper end of the wine outlet joint 6 is embedded in the wine outlet 34 near the side of the wine outlet 34, and the upper end face of the wine outlet joint 6 is close to the upper side face of the wine outlet 34. When the beer flows out of the beer outlet, it still maintains an upward flow trend so that most of the beer enters the annular groove 3210, and because the upper end of the beer outlet joint 6 is close to the side of the beer outlet 34 and is embedded in the beer outlet 34, and the upper end face of the beer outlet joint 6 is close to the upper side face of the beer outlet 34 with only a small gap, when the beer flows out of the beer outlet, most of the beer will not directly enter the beer outlet cavity 321, but will flow upward to the annular groove 3210, and then the beer will be buffered in the annular buffer cavity 35 before entering the beer outlet cavity 321, which can better reduce the impact of the beer on the valve core assembly 4, thereby reducing foam, making the beer dispensing effect better and improving the drinking taste of the beer.

[0039] like Figure 2 As shown, a wine guide tube 7 is further provided in the wine bag 5. The upper end of the wine outlet connector 6 is threadedly connected to the inner wall of the wine inlet hole 311. The upper end of the wine guide tube 7 is sleeved on the wine outlet connector 6, and the lower end of the wine guide tube 7 extends to the bottom of the wine bag 5. By providing the wine guide tube 7, the beer in the wine bag 5 can flow upward along the wine guide tube 7, thereby facilitating the beer to flow out of the wine bag 5 and preventing beer residue in the wine bag 5.

[0040] like Figure 3 and Figure 5 As shown, the raised portion 324 is provided with a wine-passing notch 326 with both ends penetrating the side wall of the wine outlet portion 322 and the side wall of the annular groove 3210. A wine-passing opening 34 is formed between the wine-passing notch 326 and the upper side surface of the top plate portion 313. This design not only facilitates the processing of the wine-passing opening 34, but also allows the beer to flow along the upper side surface of the top plate portion 313 during the process of passing from the annular buffer chamber 35 through the wine-passing opening 34 and into the wine-discharging channel 321. This prevents the beer from flowing in an up-and-down manner, allowing the beer to flow more smoothly into the wine-discharging channel 321, thereby reducing the generation of foam and improving the quality of the beer.

[0041] like Figure 3 、 Figure 6 、 Figure 7As shown, the top plate 313 includes a cylindrical wine guide 314 in the middle. The wine guide 314 is inserted into the wine outlet 322. The wine guide 314 is provided with a strip-shaped notch 315 arranged along its axial direction, with the lower end of the strip-shaped notch 315 facing the wine outlet 34. The design of the wine guide 314, because it is inserted into the wine outlet 322, allows the two to be plugged together and radially position the bottle body 31 and the connector 32 relative to each other, thereby improving the connection stability between the bottle body 31 and the connector 32. Furthermore, after beer enters the strip-shaped notch 315 from the wine outlet 34 and then enters the wine guide 314, the wine guide 314 guides the flow of beer, allowing the beer to flow only upward out of the wine outlet 321 and not into the annular buffer chamber 35. This results in a more orderly and smoother beer flow, thereby improving the quality of the beer.

[0042] like Figure 3 、 Figure 5 、 Figure 8 and Figure 9 As shown, the raised portion 324 is provided with a clearance notch 327, within which is located an exhaust nozzle 328 integrally formed with the raised portion 324. The top plate portion 313 has a socket portion 317 on its upper side that communicates with the exhaust passage 316. The exhaust nozzle 328 is inserted into the socket portion 317 and forms a seal with the inner wall of the socket portion 317. When the pressure within the barrel body 1 decreases, the gas cylinder 2 releases gas, which can sequentially pass through the exhaust passage 316 and the exhaust nozzle 328 into the barrel body 1, thereby ensuring that the pressure within the barrel body 1 meets the wine dispensing pressure requirement. This pressure compresses the wine bag 5 to dispense the wine.

[0043] like Figure 5 and Figure 6 As shown, the raised portion 324 is further provided with a positioning notch 329 having two parallel limiting sidewalls. The top plate portion 313 has two parallel positioning ridges 318 on its upper side. Both positioning ridges 318 are located within the positioning notch 329 and abut against the two limiting sidewalls of the positioning notch 329. This design ensures that the connector 32 is circumferentially positioned relative to the bottle mouth body 31. During assembly or use of the wine barrel, the positioning ridges 318 limit the rotation of the connector 32, thereby protecting the exhaust nozzle 328 from deformation or even tearing.

[0044] like Figure 2As shown, a piston 9 is also slidably disposed within the bottle mouth body 31. The upper side of the piston 9 forms a sealed pressure chamber 10. The lower side of the piston 9 is provided with a trigger plate 11. The trigger plate 11 is located in communication with the exhaust channel 316. Therefore, the pressure at the location of the trigger plate 11 is always consistent with the pressure in the space between the barrel body 1 and the wine bag 5. When the wine barrel is in use, the wine bag 5 contains beer, which can also be other alcoholic beverages besides beer. During use, as the beer in the wine bag 5 gradually flows out, the gas pressure in the barrel body 1 gradually decreases. At this time, the piston 9 moves downward under the action of the pressure chamber 10, pushing the trigger plate 11 downward together, and then pushing the cylinder valve 12 downward to open the cylinder valve 12. At this time, the gas in the gas cylinder 2 is discharged into the space outside the wine bag 5 in the barrel body 1 through the exhaust channel 316 and the exhaust nozzle 328, causing the gas pressure in the barrel body 1 to increase. After the gas pressure reaches a set value, it pushes the piston 9 upward to close the cylinder valve 12. In this way, the gas pressure in the barrel body 1 is maintained within a certain range to meet the requirements of wine discharge.

[0045] When the wine barrel is dispensing wine, the outside of the wine bag 5 is subjected to gas pressure, and the beer in the wine bag 5 can be introduced into the wine inlet hole 311 through the wine guide tube 7. At this time, since there is also an annular buffer chamber 35 in the bottle mouth 3, and the wine outlet channel 321 and the annular buffer chamber 35 are connected through the wine outlet 34, this arrangement allows most of the beer flowing out of the wine inlet 311 to first enter the annular buffer chamber 35, and then flow into the wine outlet channel 321 through the wine outlet 34, and then flow out from the wine outlet channel 321 for people to drink. Due to the design of this beer barrel, after the beer flows out of the beer outlet 81, most of the beer first enters the annular buffer chamber 35 instead of directly flowing into the beer outlet channel 321. The annular buffer chamber 35 is annular and arranged around the outer circumference of the beer outlet channel 321. Therefore, after entering the annular buffer chamber 35, the beer will be decelerated, buffered and form a regular circumferential flow, and the flow process is relatively smooth. In this way, most of the beer enters the beer outlet channel 321 after being decelerated and buffered by the annular buffer chamber 35. Therefore, the impact on the valve core assembly 4 can be greatly reduced, and the foam can be effectively reduced to improve the quality of the beer, thereby improving the drinking taste of the beer.
