Description

Technical Field

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

[0002] A dispenser is a device that connects to the top of a beer keg and works in conjunction with a beer spear inside the keg to draw beer out of the keg. When the operator pulls the handle on the dispenser, the beer tube inside the dispenser extends or retracts. When the beer tube moves downwards, it pushes open the valve on the beer spear, opening the beer passage. Simultaneously, an external air source connects to the keg, allowing gas to pass through the dispenser and beer spear into the keg, thus forcing the beer out of the keg.

[0003] A more traditional dispenser, such as the beer keg dispensing valve disclosed in patent document (application number: 201310513342.9), includes a valve body, a dispensing tube, and a handle. The valve body has a through guide hole in the center, and an air inlet pipe communicating with the guide hole on the side of the valve body. The dispensing tube, also known as the top core, is located at the guide hole and is sealed to the valve body. Its function is not only to discharge beer from the keg, but also to push down on the valve core under the action of the handle to connect the beer path and the air path. An air outlet is formed between the bottom of the valve body and the dispensing tube, which can communicate with the inside of the beer keg. The handle is hinged to the valve body and connected to the wine guide tube. The wine guide tube has an air intake structure on its side. The handle of the wine dispensing valve is hinged to the valve body, and the protrusion on the handle is always locked in the groove of the wine guide tube to achieve linkage between the two. Therefore, the wine guide tube is difficult to remove from the valve body unless the handle is removed. The wine dispensing valve is usually used as a non-removable whole. After use, the whole unit is rinsed. However, with the increasing food safety requirements, and the fact that rinsing the whole unit, especially rinsing the inside of the wine guide tube, is also quite troublesome, a dispenser with a replaceable wine guide tube has emerged. After use, the wine guide tube can be directly replaced.

[0004] The beverage dispensing system disclosed in patent document (application number: 201880051409.2) includes a one-way dispensing line and a dispensing head. The one-way dispensing line includes a flexible tube and a connecting unit, also called a top core, for the beverage to pass through and for pressing down on a valve on a barrel. The connecting unit includes a first part and a second part. The lower end of the first part is inserted into the upper end of the second part, and the two are connected by a tight fit. During assembly, the connecting unit needs to be inserted downward from the upper end of the dispensing head. After the connecting unit falls in, the actuation handle is pulled downward, which can press the connecting unit downward, and the lower end of the connecting unit presses down on the valve on the barrel. The actuation handle has protruding legs, and the top of the first part has a protrusion with a flange. During disassembly, the legs on the actuation handle hook onto the flange, thereby lifting the first part upward and separating it from the second part, leaving the second part inside the dispensing head.

[0005] However, the above structure has shortcomings. First, because the connecting unit is a columnar structure with a large outer diameter at the top and a small outer diameter at the bottom, it is inserted quite deep into the dispensing head. Therefore, when inserting the connecting unit by hand, it will not make contact with the dispensing head. At this point, the connecting unit needs to be released to allow it to fall freely for a considerable distance until the lower end of the connecting unit contacts and abuts against the valve on the barrel. However, if the connecting unit is slightly off-center during insertion, especially if the release posture is not precise, it can easily lead to a slight misalignment of the connecting unit when it falls, jamming between the connecting unit and the inner wall of the dispensing head, and inaccurate contact between the lower end and the valve on the barrel, affecting the final accuracy of the connecting unit. Furthermore, pressing down the actuation handle can also cause inaccurate alignment between the connecting unit and the valve on the barrel, affecting the sealing effect of the wine passage. This makes it difficult to accurately align and correct the connecting unit each time it is inserted. Second, disassembly requires manual force to pull the connecting unit out, and only the first part can be pulled out. The second part will remain inside the dispensing head and is difficult to remove, making disassembly inconvenient. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a dispenser that solves the problem of how existing dispensers can ensure the accuracy of their fit with the wine spear after assembly while facilitating easy disassembly and reassembly.

[0007] The objective of this invention can be achieved through the following technical solution: a dispenser, comprising a valve body and a columnar top core, wherein the valve body is hinged with a handle that can press the top core downward when it is inserted vertically from the upper end of the valve body, characterized in that the valve body is provided with an elastic element whose lower end abuts against and is supported on the valve body, and the outer wall of the top core has a radially protruding abutment portion located at the upper part of the top core, wherein when the top core is inserted downward into the valve body, the abutment portion can press downward against the upper end of the elastic element and compress the elastic element downward under the pressing action of the handle.

[0008] The top insert is inserted into the valve body from the top and pressed down into the valve body through the handle. After releasing the handle, the top insert can also be removed from the top of the valve body, making it removable and replaceable. An elastic element is installed inside the valve body; its lower end rests against the valve body, generating an upward elastic force. The top insert has a support portion on its outer wall, located at the top of the top insert. Therefore, during assembly, the valve body is first attached to the barrel's spout, then the top insert is held vertically and inserted into the valve body from the top. The top insert will not fall freely; instead, the lower end of the top insert is passed through the elastic element, and the top insert is placed on the elastic element, so that the support portion rests against the upper end of the elastic element. This entire process is performed by holding the top insert. After the top insert is released, it is supported by the elastic element, and there is no free fall process because the support portion is on the upper part of the top insert. Therefore, the lower end of the top core hangs freely, maintaining a vertical position through its own center of gravity. This ensures accurate posture and eliminates the need for repeated calibration of the top core's position and posture during assembly, making assembly more convenient. The handle acts on the upper end of the top core, its position close to that of the elastic element, allowing the top core to be stably supported on the elastic element. Pressing the top core down against the elastic element compresses it, and the top core is also pressed against the handle by the elastic element's reaction force, keeping the top core in a constrained state throughout the pressing process. This results in a more precise position after pressing down, ensuring accurate engagement with the spear. After the top core is assembled, the elastic element is in a compressed, energy-storing state. Therefore, disassembling the top core only requires pulling the handle upwards to release it; the elastic element will spring the top core upwards, eliminating the need for manual lifting and making disassembly convenient.

[0009] In the aforementioned dispenser, the upper end of the elastic element is located at the upper port of the valve body. A limiting member is also connected to the upper port of the valve body, which serves to abut the upper end of the elastic element before the top core is inserted into the valve body. Because the upper end of the elastic element is located at the upper port of the valve body, when the top core is inserted by hand, the abutting part can abut against the upper end of the elastic element, allowing the top core to receive timely support from the elastic element. Before the top core is inserted, the upper end of the elastic element abuts against the limiting member, thus the elastic element is in a certain compressed state, maintaining a certain elastic support force. This prevents the abutting part from abutting against the upper end of the elastic element and releasing the top core due to its own gravity, which would affect stability and thus ensure the accurate posture of the top core.

[0010] In the aforementioned distributor, the limiting component includes a limiting ring fixed within the upper port of the valve body. This limiting ring is coaxially aligned with the inner cavity of the valve body, and its inner circumferential wall protrudes radially inward from the side wall of the valve body's inner cavity. Before the top core is inserted into the valve body, the upper end of the elastic element abuts against the lower end face of the limiting ring. The limiting ring has a more regular structure, serving as abutment for the upper end of the elastic element and preventing the elastic element from falling out of the valve body after the top core is disassembled.

[0011] In the aforementioned distributor, the abutment portion is annular, and its outer circumferential surface is cylindrical. When the top core is inserted downward into the valve body, the outer circumferential surface of the abutment portion slides into contact with the inner circumferential surface of the limiting ring. Since the elastic element is located below the limiting ring, the outer circumferential surface of the abutment portion has already contacted and slidably engaged with the inner circumferential surface of the limiting ring before the abutment portion comes into contact with the elastic element. This allows the limiting ring to guide the upper end of the top core, ensuring the posture and stability of the top core.

[0012] In the aforementioned dispenser, the inner circumferential wall of the lower part of the valve body has an annular guide portion. The lower end of the elastic element abuts against the upper end surface of the supporting guide portion. When the top core is inserted downward into the valve body, the outer circumferential surface of the top core slides into contact with the inner circumferential surface of the guide portion. During the downward pressing of the top core, the sliding contact between the outer circumferential surface of the top core and the inner circumferential surface of the guide portion guides the lower end of the top core. The guide portion, combined with the limiting ring, makes the top core more stable and the positional accuracy after pressing higher, thereby ensuring the fitting accuracy between the top core and the nozzle.

[0013] In the aforementioned distributor, a pressure relief groove is axially formed on the inner circumferential surface of the limiting ring. The two ends of this groove penetrate the end faces of both ends of the limiting ring. The upper inner edge of the limiting ring has a guide cone surface along its circumferential direction. After the top core and valve body are assembled, an air intake channel is formed between the lower end of the top core and the valve body. To prevent gas leakage between the top core and the valve body, a sealing groove is formed on the inner circumferential surface of the guide portion. A rubber ring is installed in the sealing groove, forming a seal with the outer circumferential surface of the top core. The outer circumferential surface of the abutment portion also forms a sliding fit with the inner circumferential surface of the limiting ring, making it difficult for air below the abutment portion of the top core to escape. Therefore, a pressure relief groove is formed on the inner circumferential surface of the limiting ring to allow air to escape when the top core is assembled and pressed down, making the pressing operation easier. When the top core is disassembled and pops up, air enters, and the popping up is smoother under the action of the elastic element. The guide cone surface guides the end of the top core during insertion, making insertion more convenient and faster.

[0014] In the aforementioned distributor, the inner wall of the upper port of the valve body has a relief groove circumferentially. The limiting ring is located within the relief groove, and the outer circumferential surface of the limiting ring is connected to the groove wall via a threaded connection. The limiting ring and the valve body are connected via a threaded connection, thus allowing adjustment of the limiting ring's height, thereby adjusting the position of the upper end of the elastic element and the preload force to accommodate different types of top cores and improve versatility.

[0015] In the aforementioned distributor, the elastic element includes several butterfly springs stacked vertically, with the lowest butterfly spring resting downwards against the upper surface of the guide portion, and the highest butterfly spring resting upwards against the lower surface of the limiting ring. The inner edge of each butterfly spring protrudes radially inwards from the inner circumferential surface of the limiting ring. There is a certain width between the inner and outer edges of the butterfly springs, allowing them to abut against the lower surface of the limiting ring via the outer edge when the top core is not inserted into the valve body, and against the inner edge when the top core is inserted.

[0016] In the aforementioned dispenser, the top core has an axially oriented outlet hole. A connecting pipe is fixed to the upper end of the outlet hole, with its upper end extending upwards beyond the outlet hole. A through-hole is provided on the side wall of the handle, within which a clamping element is fixedly connected. When the handle is pressed downwards against the top core, the clamping element can grip the outer wall of the connecting pipe. The connecting pipe is used to connect to a flexible hose, and the installation notch allows the connecting pipe to pass through, preventing interference with the handle. The clamping element grips the connecting pipe, thus generating an upward pulling force on the connecting pipe when the handle is pulled upwards. This pulling force assists the elastic element in easily pulling the top core out of the dispensing spear during initial disassembly. This structure serves as a safeguard, preventing the elastic element from being unable to eject the top core due to excessive tightness between the seal in the dispensing spear and the top core.

[0017] In the aforementioned dispenser, the clamping component includes a clamping block fixed within the mounting notch. This clamping block is made of rubber, and its side wall has a through-hole. The width of this through-hole is smaller than the outer diameter of the connecting pipe. When the handle presses downwards against the top core, the connecting pipe is inserted into the clamping hole. The clamping component is a rubber clamping block, not a linkage component, simplifying the structure. The top core is pulled upwards by friction, and this structure also facilitates the assembly and disassembly of the connecting pipe and the handle.

[0018] Compared with existing technologies, this dispenser has the following advantages:

[0019] 1. Since the operation of inserting the top core into the valve body until the abutment part is supported against the upper end of the elastic element is all done by hand, and the top core is supported by the elastic element after being released, there is no process of the top core falling freely. Since the abutment part is on the upper part of the top core, the lower end of the top core hangs down freely. It is kept in a vertical state by its own center of gravity, and the posture is more accurate. There is no need to repeatedly calibrate the position and posture of the top core during the assembly process, making the assembly more convenient.

[0020] 2. During the compression of the elastic element, the top core is also pressed against the handle by the reaction force of the elastic element, so that the top core is always in a constrained state during the downward pressing process. As a result, the position of the top core after pressing down is more accurate, ensuring the matching accuracy with the wine spear.

[0021] 3. Since the elastic element is in a compressed and stored state after the top core is assembled, when disassembling the top core, you only need to pull the handle upward to release the top core. The elastic element can pop the top core upward, without the need to manually pull the top core, making disassembly relatively convenient.

[0022] 4. Since the upper end of the elastic element is against the limiting element before the top core is inserted, the elastic element is in a certain compressed state, maintaining a certain elastic support force. This prevents the abutting part from abutting against the upper end of the elastic element and from falling rapidly due to its own gravity when the top core is released, thus affecting stability and ensuring the accurate posture of the top core.

[0033] 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.

[0034] like Figures 1 to 3 As shown, a dispenser includes a valve body 1 and a top core 2. The valve body 1 is cylindrical with openings at both the top and bottom. An annular fastening portion 17 is located at the lower end of the valve body 1 for fastening onto a wine jug spout. A connecting flange 171 is circumferentially oriented on the inner circumferential surface of the fastening portion 17, and an annular sealing gasket 172 is fixedly connected to the connecting flange 171. A tubular connecting pipe portion 11 is located on the outer wall of the valve body 1, and the inner hole of the connecting pipe portion 11 is an air inlet 12 communicating with the inner cavity of the valve body 1. A handle 3 is hinged to one side of the upper edge of the valve body 1, and a locking part 18 protruding upwards is provided on the other side. A slot 181 is provided on the outer wall of the locking part 18. A pressing seat 31 protrudes on the handle 3. When the handle 3 swings upwards, the upper port of the valve body 1 can be opened. A locking pin 32 is installed on the handle 3. When the handle 3 swings downwards, it can swing to the upper port of the valve body 1 and fit on the locking part 18. The locking pin 32 can be inserted into the slot 181 to lock the handle 3. At this time, the pressing seat 31 is located inside the upper port of the valve body 1 and is set downwards.

[0035] Combination Figure 4 , Figure 5 As shown, the inner wall of the valve body 1 is cylindrical. The lower inner wall of the valve body 1 has a circumferentially annular guide portion 15. The upper end face of the guide portion 15 is flat. A limiting ring 5 is fixed inside the upper port of the valve body 1. This limiting ring 5 is coaxially arranged with the inner cavity of the valve body 1, and the inner circumferential surface of the limiting ring 5 protrudes radially inward from the inner wall of the valve body 1. An elastic element 4 is provided inside the valve body 1. This elastic element 4 consists of several butterfly springs 41. The butterfly springs 41 are wavy in the circumferential direction. These butterfly springs 41 are stacked vertically, with the lowermost butterfly spring 41 pressing downward against the upper end face of the guide portion 15. There is a certain width between the inner and outer edges of the butterfly springs 41. The uppermost butterfly spring 41 is located at the upper port of the valve body 1, and the outer edge of the uppermost butterfly spring 41 can press upward against the lower end face of the limiting ring 5. The inner edge of the butterfly spring 41 protrudes radially inward from the inner circumferential surface of the limiting ring 5. Combination Figures 6 to 9As shown, the top core 2 is cylindrical and made of plastic. The top core 2 includes an outer tube 25 and an inner sleeve 26. The upper end face of the outer tube 25 has a slot 251 circumferentially opened. The inner sleeve 26 is inserted downward into the slot 251 of the outer tube 25, and the two are engaged. The top core 2 adopts a split structure of outer tube 25 and inner sleeve 26. When the top core 2 needs to match different models of wine spears, only the matching outer tube 25 needs to be replaced, while the inner sleeve 26 can be universal, reducing production costs. The inner hole of the outer tube 25 is the wine outlet hole 22. The upper end of the inner sleeve 26 is higher than the upper end of the outer tube 25. The upper outer circumferential surface of the inner sleeve 26, which is higher than the outer tube 25, has a ring-shaped abutment part 21. That is, the abutment part 21 is located above the top core 2. The lower outer circumferential surface of the outer tube 25 has a closed conical surface 24. The abutment part 21 is coaxially arranged with the outer tube 25, and the outer diameter of the abutment part 21 is larger than the inner diameter of the butterfly spring 41. The abutment part 21 has a flat lower end face. When the top core 2 is inserted downward into the valve body 1, the lower end of the top core 2 passes downward through the butterfly spring 41. Furthermore, the lower end face of the abutment part 21 can press down against the uppermost butterfly spring 41. When the handle 3 is pulled down, the pressing seat 31 on the handle 3 can press down on the upper end of the top core 2. The top core 2 can be pressed down into the valve body 1, so that the lower end of the top core 2 pushes the valve core down and cooperates with the wine spear. The closed cone surface 24 on the top core 2 presses down on the sealing gasket 172. During this process, several butterfly springs 41 are compressed downward and store energy. After the locking pin 32 on the handle 3 is inserted into the bayonet 181 and the handle 3 is locked, several butterfly springs 41 are always in a compressed and stored energy state.

[0036] Specifically, the valve body 1 has a relief groove 16 circumferentially on the inner wall of the upper port. The limiting ring 5 is located in the relief groove 16, and the outer circumferential surface of the limiting ring 5 is connected to the groove wall of the relief groove 16 by a threaded connection. The inner circumferential surface of the limiting ring 5, the outer circumferential surface of the abutment part 21, and the inner circumferential surface of the guide part 15 are all cylindrical surfaces. The upper inner edge of the limiting ring 5 has an inlet cone surface 52 circumferentially. When the top core 2 is inserted downward into the valve body 1, the outer circumferential surface of the abutment part 21 slides with the inner circumferential surface of the limiting ring 5, and the outer circumferential surface of the top core 2 slides with the inner circumferential surface of the guide part 15. After the top core 2 is assembled with the valve body 1, an air intake channel is formed between the lower end of the top core 2 and the valve body 1. To prevent gas from leaking between the top core 2 and the valve body 1, a sealing groove 13 is circumferentially opened on the inner circumferential surface of the guide part 15. A rubber ring 14 is provided in the sealing groove 13, which can form a seal between the top core 2 and the outer circumferential surface of the top core 2 after the top core 2 is inserted. A pressure relief groove 51 is provided on the inner circumferential surface of the limiting ring 5 along the axial direction, and the two ends of the pressure relief groove 51 pass through the two end faces of the limiting ring 5 respectively.

[0037] A plastic tube 23 is fixed to the upper end of the outlet hole 22 of the top core 2. The upper end of the tube 23 extends upward from the outlet hole 22. A vertically penetrating installation notch 33 is provided on the side wall of the handle 3. A clamping block 6 is fixedly connected in the installation notch 33. The clamping block 6 is made of rubber material. A vertically penetrating clamping opening 61 is provided on the side wall of the clamping block 6. The width of the clamping opening 61 is smaller than the outer diameter of the tube 23. When the handle 3 presses down on the top core 2, the tube 23 is inserted into the clamping opening 61, and the clamping block 6 and the tube 23 are tightly fitted. When the top core 2 needs to be disassembled, the handle 3 is pulled upward. The clamping block can generate an upward pulling force on the tube 23. This pulling force can help the elastic element 4 to easily pull the top core 2 out of the wine spear in the initial stage of disassembly.

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.

[0039] Although this document frequently uses terms such as valve body 1, connecting pipe 11, and air inlet 12, the possibility of using other terms is not excluded. These terms are used 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.
