Description

Technical Field

[0001] This invention belongs to the technical field of beverage drinking equipment, and relates to a dispenser. Background Technology

[0002] A barrel is a container used to hold liquor. Typically, a barrel has a spout at its opening, containing a valve that seals the liquor inside. A dispenser, on the other hand, is a device attached to the top of the barrel and works in conjunction with the spout inside to dispense the liquor.

[0003] In the prior art, a dispenser is also known as a beer dispensing valve. For example, Chinese patent document CN103523730A discloses a beer dispensing valve for a beer keg. This dispensing valve includes a valve body, a guide tube, and a handle. The valve body has a through guide hole in its center, and an air inlet pipe communicating with the guide hole on its side. The guide tube is located at the guide hole and is sealed to the valve body. An air outlet is formed between the bottom of the valve body and the guide tube, allowing communication with the inside of the beer keg. The handle is hinged to the valve body and connected to the guide tube. The guide tube has an air inlet structure on its side. When the handle moves the guide tube down along the guide hole, the air inlet structure allows communication between the air inlet pipe and the air outlet. The operating principle of this dispenser is as follows: Under normal conditions, the dispenser is in the closed state. When it is time to dispense liquor, the operator pulls the handle on the dispenser, causing the liquor guide tube to move downwards and open the valve core on the liquor spear. At this time, the liquor path is opened, and the external air source can also be connected to the liquor barrel, allowing the gas to pass through the dispenser and liquor spear in sequence into the liquor barrel, thereby forcing the liquor out of the barrel. At this time, the dispenser is in the dispensing state.

[0004] When it's time to change the barrel, the dispenser needs to be disconnected from the barrel and removed. However, existing dispensers have the following drawbacks during disassembly: Before disassembly, to avoid leakage, the dispenser needs to be returned to the closed position. At this time, the dispenser's air inlet and outlet are not connected, and the spout is closed. In other words, the space at the outlet of the dispenser's valve body is a sealed space called the air chamber. After the dispenser is used, high-pressure gas remains in the air chamber. This high-pressure gas presses the sealing ring at the junction of the dispenser and the spout tightly against the mating surface, making disassembly very difficult. In response, those skilled in the art can generally think of two conventional technical means to solve the above problems: one is to remove the air inlet pipe inserted into the distributor before disassembling the distributor, so that the gas in the air chamber can be released from the original air inlet structure. This method requires disassembly and reassembly of the air inlet pipe, which is quite troublesome; the other is to open a pressure relief hole on the valve body of the distributor to connect to the air chamber, and then install a pressure relief valve in the pressure relief hole to release the gas remaining in the air chamber. This design will make the distributor structure more complicated and the cost higher. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a dispenser. The technical problem solved by this invention is that disassembling existing dispensers is extremely laborious.

[0006] The objective of this invention can be achieved through the following technical solution: A dispenser includes a valve body and a wine guide tube. The valve body has a guide hole, an air inlet, and an air chamber communicating with the guide hole. A sealing ring is provided on the inner wall of the guide hole. The outer periphery of the wine guide tube has a sealing part that can form a seal with the inner wall of the guide hole through the sealing ring. The wine guide tube is characterized in that it also has a venting groove and a sliding part on its outer periphery. The sealing part is located above the venting groove, and the sliding part is located below the venting groove. The sliding part slides with the inner wall of the guide hole, and an exhaust gap communicating with the venting groove is formed between them. A valve core for controlling the opening and closing of the air inlet is provided in the air inlet. When the dispenser is in the closed state, the valve core blocks the air inlet, the venting groove is positioned opposite the sealing ring and communicates with the outside, and the sealing part does not form a seal with the inner wall of the guide hole.

[0007] Unlike existing technologies that use methods such as pulling out the air tube or setting a pressure relief valve to release the accumulated air in the air chamber, this invention improves the design of the distributor's guide tube structure and adds a valve core in the air inlet, so that no air will accumulate in the distributor's air chamber under normal conditions, thus completely solving the problem of difficult disassembly of the distributor. Specifically, a venting groove and a sliding part are sequentially arranged on the outer periphery of the wine guide tube located below the sealing part. The sliding part slides with the guide hole, and an exhaust gap communicating with the venting groove is formed between them. This allows the air chamber to form a passage to the outside through the exhaust gap in the guide hole and the venting groove. The design of the venting groove ensures smooth ventilation, and due to the sliding fit between the sliding part and the guide hole, the wine guide tube is not prone to shaking relative to the guide hole, thus maintaining a stable conduction state of the above passage. At the same time, a valve core for controlling the opening and closing of the air inlet is set in the air inlet. When the distributor is in the closed state, the air inlet is blocked by the valve core, the sealing part is located above the sealing ring, and the venting groove is positioned opposite the sealing ring and communicates with the outside. That is to say, no seal is formed between the guide hole and the sealing part at this time. In other words, the air chamber under normal conditions remains connected to the outside through the exhaust gap in the guide hole and the venting groove designed above, and there will be no air accumulation. It is very easy and effortless for people to remove the distributor. When the dispenser is in the dispensing state, the valve core opens, connecting the air inlet to the guide hole. The venting groove then moves down with the dispensing tube to a position below the sealing ring. At this time, the sealing part moves down and forms a seal with the sealing ring, isolating the venting groove from the outside. In other words, when dispensing, the above passage is closed, and high-pressure gas can only enter the air chamber through the air inlet, preventing leakage. Furthermore, the above passage structure of the present invention does not rely on external structures and utilizes the original components of the dispenser, resulting in a simple overall structure that does not increase costs.

[0008] In the aforementioned dispenser, the vent groove is annular and surrounds the wine guide tube circumferentially. This design ensures unobstructed ventilation, preventing air accumulation in the air chamber under normal conditions, thus making disassembly of the dispenser effortless and convenient.

[0009] In the aforementioned distributor, the upper edge of the vent groove has an upper air guide surface with an outwardly convex arc shape. This design allows the vent groove to connect with the outside environment, ensuring unobstructed ventilation and preventing air accumulation in the air chamber under normal conditions. This, in turn, makes disassembly of the distributor easier and less strenuous.

[0010] In the aforementioned distributor, the lower edge of the vent groove has a convex, arc-shaped lower air guide surface. This design allows the vent groove to connect with the exhaust gap, ensuring unobstructed airflow and preventing air accumulation in the air chamber under normal conditions. This, in turn, makes disassembly of the distributor easier and less strenuous.

[0011] In the aforementioned distributor, the inner wall of the guide hole has an inwardly protruding, annular retaining ring. The sealing ring is embedded in the inner peripheral wall of the retaining ring, and the sealing part can slide with the retaining ring. The sliding part is annular with an outer diameter larger than the inner diameter of the retaining ring and is located below the retaining ring. The outer peripheral surface of the sliding part is radially higher than the opening surface of the vent groove. Through the inward protrusion design of the retaining ring and the outward protrusion design of the sliding part, the outer peripheral surface of the sliding part and the opening surface of the vent groove can be offset by a certain distance. This makes the gap formed between the opening surface of the vent groove and the inner wall of the guide hole larger than the exhaust gap formed between the surface of the sliding part and the inner wall of the guide hole. This improves the ventilation effect of the passage formed by the exhaust gap and the vent groove, thereby ensuring smooth ventilation and preventing air accumulation in the air chamber under normal conditions, making the distributor easy and effortless to disassemble.

[0012] In the aforementioned distributor, the transition between the outer peripheral surface of the sliding part and the opening surface of the vent groove has a guide slope inclined towards the vent groove. This design facilitates communication between the exhaust gap and the vent groove, ensuring unobstructed ventilation and preventing air accumulation in the air chamber under normal conditions. This, in turn, makes disassembly of the distributor easier and less strenuous.

[0013] In the aforementioned distributor, the lower edge of the retaining ring has an upwardly inclined second air guide slope. When the distributor is in the closed state, the second air guide slope and the first air guide slope form a gap. This design facilitates the connection between the exhaust gap and the ventilation groove, ensuring unobstructed ventilation and preventing air accumulation in the air chamber under normal conditions. This makes disassembly of the distributor easier and less strenuous.

[0014] In the aforementioned distributor, the upper edge of the retaining ring has a guide cone surface. This design allows the guide cone surface to facilitate the connection between the vent groove and the outside environment, ensuring unobstructed airflow and preventing air accumulation in the air chamber under normal conditions. This, in turn, makes disassembly of the distributor easier and less strenuous.

[0015] In the aforementioned distributor, the retaining ring is located on the inner wall of the guide hole near the upper port. An annular mounting groove is formed on the inner circumferential wall of the retaining ring, and the sealing ring is embedded in the mounting groove with its inner ring portion protruding from the groove. Through this design, when the sealing part moves up and down, its upward movement disengages from the sealing ring to guide air, while its downward movement allows it to contact the sealing ring to form an effective seal. Furthermore, the position of the retaining ring near the upper port of the guide hole helps to shorten the distance between the venting groove and the external space under normal conditions, making ventilation smoother and ensuring that no air accumulates in the air chamber under normal conditions. This makes disassembly of the distributor easier and less strenuous.

[0016] In the aforementioned distributor, the air inlet includes, from the outside in, three holes: hole one, hole two, and hole three. The diameter of hole one is larger than that of hole two, and the diameter of hole two is larger than that of hole three. Hole three is connected to a guide hole. A valve cap is fixed to the outer end of hole two, and the valve cap has a through hole that connects hole two and hole one. The valve core is located inside hole two, and a spring is provided between it and the valve cap. Under the elastic force of the spring, the valve core can block hole three, and part of the valve core protrudes from hole three and is located in the guide hole. The guide tube can move downward and push the valve core to open hole three. With the above design, when the distributor is in the closed state, the valve core blocks hole three under the action of the spring, thus preventing the air inlet from communicating with the guide hole. In this way, under normal conditions, the air chamber can only communicate with the outside through the exhaust gap and the vent groove, thus ensuring that air will not accumulate in the air chamber under normal conditions, and making the distributor easy to disassemble.

[0017] Compared with existing technologies, this distributor has the following advantages: By improving the design of the ventilation groove and sliding section on the wine guide tube and the matching design of the valve core in the air inlet, this distributor ensures that there is no air accumulation in the air chamber when the distributor is in the closed state, thereby avoiding the problem of difficult disassembly due to high pressure air accumulation; at the same time, this distributor has a simple improved structure and low manufacturing cost.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] Specifically, such as Figure 1 As shown, this dispenser includes a valve body 1 and a wine guide tube 2. Figure 3 As shown, the valve body 1 has a guide hole 11, an air inlet 12, and an air chamber 13. The upper end of the guide hole 11 communicates with the outside, and the lower end communicates with the air chamber 13. The air inlet 12 is located on one side of the guide hole 11 and also communicates with the guide hole 11. A valve core 5 for controlling the opening and closing of the air inlet 12 is provided inside the air inlet 12. The air inlet 12 includes, from the outside to the inside, three holes: hole 121, hole 22, and hole 33. The diameter of hole 121 is larger than that of hole 222, and the diameter of hole 222 is larger than that of hole 33. Hole 33 is connected to guide hole 11. A valve cap 7 is fixedly connected to the outer end of hole 222. The valve cap 7 has a through hole 71 that connects hole 222 and hole 121. The valve core 5 is located inside hole 222 and a spring 8 is provided between it and the valve cap 7. Under the elastic force of the spring 8, the valve core 5 can block hole 33, and part of the valve core 5 extends out of hole 323 and is located inside guide hole 11. The guide tube 2 can move downward and push the valve core 5 to open hole 323.

[0027] For example Figure 2 , Figure 3 and Figure 4As shown, a sealing ring 3 is provided on the inner wall of the guide hole 11, and a sealing part 21 is provided on the outer periphery of the wine guide tube 2, which can form a sealing fit with the inner wall of the guide hole 11 through the sealing ring 3. A venting groove 22 and a sliding part 23 are also provided on the outer periphery of the wine guide tube 2, which are arranged in an annular shape and circumferentially around the wine guide tube 2. The upper edge of the venting groove 22 has an upper venting surface 221 with an outwardly convex arc shape. The lower edge of the venting groove 22 has a lower venting surface 222 with an outwardly convex arc shape. The sealing part 21 is located above the venting groove 22, and the sliding part 23 is located below the venting groove 22. The sliding part 23 slides with the inner wall of the guide hole 11, and an exhaust gap 4 communicating with the venting groove 22 is formed between them. When the distributor is in the closed state, the valve core 5 blocks the air inlet 12, the sealing part 21 is located above the sealing ring 3 and no seal is formed between it and the inner wall of the guide hole 11, and the venting groove 22 is positioned opposite the sealing ring 3 and communicates with the outside. At this time, the air chamber 13 is connected to the outside through the passage formed by the exhaust gap in the guide hole 11 and the venting groove 22, and there is no air accumulation in the air chamber 13.

[0028] For example Figure 5 and Figure 6 As shown, when the dispenser is in the dispensing state, the valve core 5 is pushed open by the wine guide tube 2, so that the air inlet 12 communicates with the guide hole 11. The venting groove 22 moves down with the wine guide tube 2 to a position below the sealing ring 3. At the same time, the sealing part 21 also moves down together to form a seal with the sealing ring 3, so that the venting groove 22 is isolated from the outside. That is to say, the above passage is sealed at this time. Then, the high pressure gas enters the air chamber 13 through the air inlet 12, and then enters the wine barrel through the air chamber 13 to force the wine to be dispensed.

[0029] More specifically, such as Figures 3 to 6 As shown, in this embodiment, the inner wall of the guide hole 11 has an inwardly protruding, annular retaining ring 14. The retaining ring 14 is located on the inner wall of the guide hole 11 near the upper port. An annular mounting groove 143 is formed on the inner peripheral wall of the retaining ring 14. The sealing ring 3 is embedded in the mounting groove 143, and the inner ring portion of the sealing ring 3 protrudes from the mounting groove 143. The sealing part 21 can slide with the retaining ring 14. The sliding part 23 is annular and its outer diameter is larger than the inner diameter of the retaining ring 14 and it is located below the retaining ring 14. The outer peripheral surface of the sliding part 23 is radially higher than the opening surface of the venting groove 22. The transition between the outer peripheral surface of the sliding part 23 and the opening surface of the venting groove 22 has a guide slope 24 that is inclined towards the venting groove 22. The upper edge of the retaining ring 14 has a guide cone surface 142. The lower edge of the baffle ring 14 has an upwardly inclined air guide slope 2 141. When the distributor is in the closed state, the air guide slope 2 141 and the air guide slope 1 24 form a gap 6.

[0030] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0031] Although this document frequently uses terms such as valve body 1, guide hole 11, air inlet 12, hole one 121, hole two 122, hole three 123, air chamber 13, retaining ring 14, air guide slope two 141, air guide cone 142, mounting groove 143, wine guide tube 2, sealing part 21, vent groove 22, upper air guide surface 221, lower air guide surface 222, sliding part 23, air guide slope one 24, sealing ring 3, exhaust gap 4, valve core 5, gap 6, valve cap 7, through hole 71, and spring 8, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention.
