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, with the lower end of the first part inserted into the upper end of the second part. The two parts are connected by a tight fit. During assembly, the connecting unit needs to be inserted downwards from the upper end of the dispensing head. After the connecting unit falls in, the actuation handle is pulled downwards. The lower side of the actuation handle has a downwardly protruding clamping element. (This is related to the appendix of the patent document.) Figure 7As can be seen, the lower end face of the clamping element is an arc surface. When the actuation handle is pulled downwards, the clamping element abuts against the upper end face of the connecting unit through its arc-shaped lower end face, thereby pressing the connecting unit downwards into the dispensing head. However, after the connecting unit is pressed into the dispensing head, its lower end needs to be inserted into the valve body of the wine spear and push open the valve core on the wine spear. During long-term wine dispensing, the connecting unit needs to engage with the sealing ring inside the wine spear to achieve a wine path seal and prevent wine leakage into the air intake channel. Furthermore, the wine barrel is pressurized by injecting gas into the barrel to force out the wine from the wine bag, resulting in a relatively high pressure inside the wine bag, which leads to high requirements for the sealing fit between the connecting unit and the sealing ring. However, the connecting unit and the dispensing head are detachable structures, and there is a certain assembly gap after the connecting unit and the dispensing head are assembled. The lower end face of the clamping element is an arc surface, and the arc surface is in line contact with the upper end face of the connecting unit. When the connecting unit is pressed downwards, it is easy to cause a slight misalignment of the connecting unit, which in turn affects the sealing fit between the connecting unit and the sealing ring inside the wine spear, thus affecting the sealing performance. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a dispenser that solves the problem of low precision in the fit between the top core and the wine spear after assembly, which affects the sealing effect of the wine path.

[0006] The objective of this invention can be achieved through the following technical solution: A dispenser includes a valve body, a columnar core, and a handle hinged to the valve body at one end. The lower side of the handle has a pressing part that protrudes downward and can press the core downward into the valve body when the handle is pulled down. A locking structure is provided between the valve body and the handle to lock the handle when the core is pressed into the valve body. The pressing part has a calibration slope and a limiting plane on its lower end surface. The calibration slope is located between the handle hinge point and the limiting plane, and the end of the calibration slope facing the handle hinge point is inclined upward relative to the limiting plane. The angle between the calibration slope and the limiting plane is an obtuse angle. When the core is pressed into the valve body and the handle is locked, the limiting plane faces downward and abuts against the upper end surface of the core. The valve body also has an elastic element that can generate an upward pushing force on the core.

[0007] The top insert is inserted into the valve body from the top and pressed down into the valve body through the pressing part on the handle. After the handle is released, the top insert can also be removed from the top of the valve body, making it removable and replaceable. The pressing part has a calibration ramp and a limiting plane, with the calibration ramp closer to the hinge end of the handle. The valve body has an upward-pushing elastic element. Therefore, during assembly, first, the valve body is attached to the barrel's spout. Then, holding the top insert vertically, it is inserted into the valve body from the top. The top insert rests against the elastic element. Pulling the handle down causes the calibration ramp, closer to the handle's hinge point, to swing to a horizontal position and rest against the upper surface of the top insert. This pre-positioning of the top insert before pressing down calibrates its position and orientation, ensuring it remains vertical. As the handle is further pressed down until locked onto the valve body by the locking mechanism, the top insert is also pressed into place, at which point the limiting plane... The top surface of the top core is pressed against the upper surface of the pressing part to achieve surface contact. The elastic element continuously exerts an upward thrust on the top core. This thrust ensures that the upper surface of the top core is always pressed against the limiting plane of the pressing part, so that the limiting plane acts as a reference plane. The top core remains vertical with the limiting plane as a reference, avoiding tilting of the top core. This makes the position of the lower end of the top core more accurate. That is, although the pressing part is provided with two planes, the calibration slope and the limiting plane, these two planes are not used to press the top core in surface contact. The calibration slope is used to calibrate the position and posture of the top core before pressing down, and the limiting plane is used to restrict and maintain the position of the top core after pressing down. This ensures the fitting accuracy between the lower end of the top core and the inner sealing ring of the wine spear, and improves the sealing effect.

[0008] In the aforementioned dispenser, the lower end of the calibration ramp is connected to the limiting plane via an arc-shaped pressing surface. The pressing part uses the calibration ramp abutting against the upper end of the top core as the initial position for pressing down on the top core. As the handle swings downward, the arc-shaped pressing surface abuts against the upper end of the top core, preventing jumping or jerking during the pressing process and making the pressing process smoother until the limiting plane abuts against the upper end of the top core. This ensures the positional accuracy of the top core throughout the pressing process and improves the fit accuracy with the inner sealing ring of the wine spear after pressing.

[0009] In the aforementioned dispenser, the upper surface of the top core is flat, and a connecting tube extends upward from the center of the upper end of the top core. The side of the handle has a through-hole for inserting the connecting tube. The lower end of the connecting tube passes through both the calibration ramp and the limiting plane, and the centerline of the connecting tube is perpendicular to the limiting plane. Since the upper end of the top core needs to be connected to a wine tube for dispensing wine, a connecting tube is provided. The connecting tube is notched on the handle to avoid the connecting tube. The connecting tube is located at the center of the top core. Therefore, the connecting tube extends through both the calibration ramp and the limiting plane, meaning both the calibration ramp and the limiting plane are close to the center of the upper surface of the top core. This allows the top core to be pressed down at its center, making it more stable under pressure. The centerline of the connecting tube is perpendicular to the limiting plane, so that when the limiting plane is horizontal and close to the upper surface of the top core, the connecting tube is inserted vertically into the connecting tube.

[0010] In the aforementioned dispenser, the calibration ramp, pressing arc surface, and limiting plane are connected in a C-shape and arranged around the lower port of the mounting notch. That is, the calibration ramp, pressing arc surface, and limiting plane are all close to the center of the upper end face of the top core, thereby generating a vertically downward pressing force on the top core as much as possible and preventing the top core from tilting.

[0011] In the aforementioned dispenser, the top core has an axially oriented outlet hole. The lower end of the connecting pipe is inserted and fixed within the outlet hole, while the upper end of the connecting pipe extends upwards beyond the outlet hole. A clamping element is fixedly connected within the mounting notch, capable of clamping the top core onto the outer wall of the connecting pipe when it is pressed into the valve body and the limiting plane abuts against the upper surface of the top core. The top core is detachable. After the top core is pressed into the valve body, the clamping element clamps onto the outer wall of the connecting pipe, thereby limiting and retaining the connecting pipe and contributing to the stability of the upper end of the top core. When the top core needs to be removed, the handle is pulled upwards, and the clamping element pulls the connecting pipe upwards, generating an upward pulling force on the top core. This prevents the top core from becoming stuck in the valve body due to excessive friction caused by the tight fit with the sealing ring, making removal of the top core more convenient and reliable.

[0012] In the aforementioned dispenser, the handle includes a handle body and a pressing seat. One end of the handle body is hinged to the valve body, and a recessed mounting cavity is located on the lower side of the handle body. The pressing seat is plate-shaped, and the pressing part is located on the lower side of the pressing seat. The outer edge of the upper side of the pressing seat has an upwardly protruding limiting flange along its circumferential direction. The limiting flange is inserted upward into the mounting cavity and fits against the side wall of the mounting cavity. The pressing seat and the handle body are fixedly connected by fasteners. The insertion of the limiting flange into the mounting cavity and its fit against the side wall of the mounting cavity ensures the positional accuracy and stability of the pressing seat, thereby ensuring the positional accuracy of the calibration slope and the limiting plane.

[0013] In the aforementioned dispenser, the mounting notch penetrates both the handle and the pressing seat. The upper side of the pressing seat has an upwardly protruding connecting flange that surrounds the mounting notch. The upper end of the connecting flange abuts against the handle, and the clamping member is fixed to the inner side of the connecting flange. The abutment between the connecting flange and the handle ensures the stability of the pressing seat, while the clamping member fixed to the connecting flange facilitates clamping the connecting pipe.

[0014] In the aforementioned dispenser, the clamping component includes a U-shaped clamping block made of rubber material, which has a clamping opening facing the mounting notch side. When the top core is pressed into the valve body and the limiting plane abuts against the upper end face of the top core, the connecting pipe is inserted into the clamping opening, and the outer wall of the connecting pipe is tightly fitted with the inner wall of the clamping block. The clamping component is a rubber clamping block, rather than a linkage component, simplifying the structure. The top core is pulled upward by friction. During assembly, the connecting pipe can be inserted into the clamping opening from the side of the handle, making disassembly and assembly relatively convenient.

[0015] In the aforementioned dispenser, both ends of the clamping block have plate-shaped mounting portions, which are arranged opposite each other. On the opposite sides of the two mounting portions, there are snap-fit ​​protrusions. Two snap-fit ​​notches are provided on the connecting flange, and the two snap-fit ​​protrusions respectively snap into the two snap-fit ​​notches. On the opposite sides of the two mounting portions, there are relatively protruding limiting protrusions. The snap-fit ​​protrusions snap into the snap-fit ​​notches, fixing the clamping block to the pressing seat. After the connecting pipe is inserted into the clamping opening, the limiting protrusions can limit the connecting pipe, preventing it from coming out and ensuring stability after assembly.

[0016] In the aforementioned distributor, the elastic element includes several butterfly springs disposed within the valve body. These butterfly springs are stacked vertically in sequence, with the lowest butterfly spring pressing downward against the valve body and the highest butterfly spring located at the upper end port of the valve body. The upper outer circumferential surface of the top core has an annular abutment portion in the circumferential direction. When the top core is inserted downward into the valve body, the abutment portion can press downward against the highest butterfly spring. The uppermost butterfly spring is located at the upper end of the valve body. Holding the top core vertically, insert it into the valve body from the top. The top core will not fall freely; instead, hold the top core and pass its lower end through the butterfly spring so that the abutment part hooks against the uppermost butterfly spring. This entire process is done by holding the top core. After the top core is released, it is supported by the butterfly spring, so 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 freely. It is kept vertical by its own center of gravity, and the posture is relatively accurate. Then, by calibrating the inclined plane to abut against the upper surface of the top core, the top core is stably supported on the butterfly spring. This makes the position of the top core after being pressed down more accurate, ensuring the precision of the match with the wine spear.

[0017] Compared with existing technologies, this dispenser has the following advantages:

[0018] 1. Because a calibration ramp is set on the pressing part, the top core is held vertically and inserted into the valve body from the top. The top core can press down against the elastic element. At this time, the handle is pulled down, and the calibration ramp can swing to the horizontal and abut against the upper surface of the top core. This allows the top core to be pre-limited by the calibration ramp before being pressed down, thereby calibrating the position and posture of the top core, so that the top core is pressed down in a vertical state, improving the positional accuracy of the top core.

[0019] 2. Because a limiting plane is set on the pressing part, when the handle is pressed down until it is locked onto the valve body by the locking structure, the top core is also pressed down into place. At this time, the limiting plane abuts against the upper end surface of the top core, achieving surface contact. The elastic element continuously generates an upward thrust on the top core. This thrust ensures that the upper end surface of the top core always abuts against the limiting plane of the pressing part, so that the limiting plane acts as a reference plane. The top core remains vertical with the limiting plane as a reference, avoiding the top core from tilting. This makes the position of the lower end of the top core more accurate, thereby ensuring the matching accuracy between the lower end of the top core and the inner sealing ring of the valve, and improving the sealing effect.

[0031] 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.

[0032] 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 14 is located at the lower end of the valve body 1 for fastening onto a wine jug spout. A connecting flange 141 is circumferentially oriented on the inner circumferential surface of the fastening portion 14, and an annular sealing gasket 142 is fixedly connected to the connecting flange 141. 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. The handle 3 can swing up and down above the valve body 1. The lower side of the handle 3 has a downwardly protruding pressing part 321. When the core 2 is vertically inserted from the upper port of the valve body 1 and the handle 3 is pulled downward, the pressing part 321 can press the core 2 downward into the valve body 1. A locking structure is provided between the valve body 1 and the handle 3, which can lock the handle 3 onto the valve body 1 after the core 2 is pressed into the valve body 1. The locking structure is an existing structure, including a length along the handle 3. A locking pin 312 is slidably disposed in the handle 3. A spring 313 is also provided in the handle 3. The upper side of the valve body 1 has an upwardly protruding locking part 15. A slot 151 is provided on the outer side of the locking part 15. An clearance slot 314 is provided on the handle 3. When the handle 3 swings downward, it can be sleeved on the locking part 15 through the clearance slot 314. When the handle 3 presses the top core 2 into the valve body 1, the locking pin 312 can be inserted into the slot 151 under the action of the spring 313, so that the handle 3 is locked.

[0033] Combination Figure 4 , Figure 5As shown, the lower end face of the pressing part 321 has a calibration slope 322, a pressing arc surface 323, and a limiting plane 324 in sequence. Both the calibration slope 322 and the limiting plane 324 are straight surfaces, while the pressing arc surface 323 is an arc surface. The calibration slope 322 is located between the hinge point of the handle 3 and the limiting plane 324. The end of the calibration slope 322 facing the hinge point of the handle 3 is inclined upwards relative to the limiting plane 324, and the angle between the calibration slope 322 and the limiting plane 324 is an obtuse angle. The pressing arc surface 323 is located between the calibration slope 322 and the limiting plane 324, and the lower end of the calibration slope 322 is connected to the limiting plane 324 via the arc-shaped pressing arc surface 323. Figure 6 As shown, the inner wall of the valve body 1 is cylindrical, and the lower inner wall of the valve body 1 has an annular guide portion 13 in the circumferential direction. The upper end surface of the guide portion 13 is flat. A limiting ring 6 is fixed in the upper end port of the valve body 1. The limiting ring 6 is coaxially arranged with the inner cavity of the valve body 1, and the inner circumferential surface of the limiting ring 6 protrudes radially inward from the inner cavity side wall of the valve body 1. A pressure relief groove 61 that runs vertically through the inner circumferential surface of the limiting ring 6 is provided for the gas in the valve body 1 to be discharged when the top core 2 is pressed in. An elastic element 5 is also provided inside the valve body 1. The elastic element 5 consists of several butterfly springs 51. The butterfly springs 51 are wavy in the circumferential direction. These butterfly springs 51 are stacked vertically, with the lowest butterfly spring 51 pressing downward against the upper end surface of the guide portion 13. There is a certain width between the inner and outer edges of the butterfly springs 51. The uppermost butterfly spring 51 is located at the upper end port of the valve body 1, and the outer edge of the uppermost butterfly spring 51 can press upward against the lower end surface of the limiting ring 6. The inner edge of the butterfly spring 51 protrudes radially inward from the inner circumferential surface of the limiting ring 6. Figure 7 , Figure 8 , Figure 9As shown, the top core 2 is cylindrical and made of plastic. The top core 2 includes an outer tube 21 and an inner sleeve 22. The lower outer circumferential surface of the outer tube 21 of the top core 2 has a closed conical surface 211. The upper end face of the outer tube 21 has a slot 212. The inner sleeve 22 is inserted downward into the slot 212 of the outer tube 21, and the two are engaged. The top core 2 adopts a split structure of outer tube 21 and inner sleeve 22. When the top core 2 needs to match different models of wine spears, only the matching outer tube 21 needs to be replaced, while the inner sleeve 22 can be universal, reducing production costs. The upper end of the inner sleeve 22 is higher than the upper end of the outer tube 21, and the upper end face of the inner sleeve 22 is a flat surface. The upper outer circumferential surface of the inner sleeve 22, which is higher than the outer tube 21, has a circumferentially annular abutment portion 221. The outer diameter of the abutment portion 221 is larger than the inner diameter of the butterfly spring 51. The abutment portion 221 has a flat lower end face. When the top core 2 is vertically inserted into the valve body 1, the lower end of the top core 2 passes downward through the butterfly spring 51, and the lower end face of the abutment portion 221 can press downward against the uppermost butterfly spring 51. At this time, the outer circumferential surface of the abutment portion 221 slides in cooperation with the inner circumferential surface of the limiting ring 6. When the handle 3 is pulled downward, the calibration slope 322 on the pressing part 321 can first swing to a horizontal position and abut against the valve body. On the upper end face of the inner sleeve 22, the top core 2 is pre-limited by the calibration slope 322 before being pressed down. As the handle 3 swings further downward, the pressing arc surface 323 abuts against the upper end face of the inner sleeve 22 and continues to press down the top core 2. The outer circumferential surface of the outer tube 21 of the top core 2 slides and engages with the inner circumferential surface of the guide part 13 of the valve body 1. The top core 2 compresses the butterfly spring 51 until the top core 2 is pressed down into place, that is, the lower end of the top core 2 pushes down to open the valve core of the wine spear, and the closed cone surface 211 on the outer tube 21 presses against the sealing gasket 142. The locking pin 312 is inserted into the bayonet 151 to lock the handle 3. At this time, the limiting plane 324 is in a horizontal state and abuts against the upper end face of the inner sleeve 22.

[0034] The inner hole of the outer tube 21 of the top core 2 is an axially penetrating wine outlet 222. A plastic connector 23 is fixed to the upper end of the wine outlet 222. The upper end of the connector 23 extends upward from the wine outlet 222, and the connector 23 is located at the center of the top core 2. Figure 10As shown, the handle 3 includes a handle body 31 and a pressing seat 32. One end of the handle body 31 is hinged to the valve body 1, and the other end is the operating end for hand gripping. A locking pin 312 is disposed in the operating end. The lower side of the handle body 31 has a recessed mounting cavity 311. The pressing seat 32 is plate-shaped, and the pressing part 321 is located on the lower side of the pressing seat 32. The outer edge of the upper side of the pressing seat 32 has an upwardly protruding limiting flange 325. The limiting flange 325 is inserted upward into the mounting cavity 311 and fits against the side wall of the mounting cavity 311. The pressing seat 32 and the handle body 31 are fixedly connected by fastening screws. The upper side of the handle 31 has a downward through mounting notch 33 that penetrates the pressing seat 32 to the calibration slope 322 and the limiting plane 324. The calibration slope 322, the pressing arc surface 323 and the limiting plane 324 are connected in a C-shape and surround the lower port of the mounting notch 33. The center line of the mounting notch 33 is perpendicular to the limiting plane 324. Since the calibration slope 322 and the limiting plane 324 are both penetrated by the mounting notch, and the long edges of both sides of the calibration slope 322 and the limiting plane 324 have arc chamfers, the calibration slope 322 and the limiting plane 324 are relatively narrow and have a small width, and are generally thin strips. At the same time, the mounting notch 33 penetrates the side of the handle 31, the pressing seat 32 and the pressing part 321, which makes it easy for the connecting pipe 23 to be inserted into the mounting notch 33 from the side opening. The upper side of the pressing seat 32 has an upwardly protruding connecting flange 326 that surrounds the mounting notch 33. The upper end of the connecting flange 326 abuts against the handle 31. A clamping member is provided within the mounting notch 33. This clamping member includes a clamping block 4 made of rubber material. The clamping block 4 is U-shaped and has a clamping opening 41 facing the side of the mounting notch 33. The width of the clamping opening 41 is slightly smaller than the outer diameter of the connecting tube 23. The outer side of the clamping block 4 fits against the inner wall of the mounting notch 33, i.e., the outer surface of the connecting flange 326. Both ends of the clamping block 4 have sheet-like mounting portions 42. These two mounting portions 42 are arranged opposite each other and fit against the opposite sides of the connecting flange 326. A snap-fit ​​protrusion 421 is provided on the opposite sides of the two mounting portions 42. Two snap-fit ​​notches 32 are provided on the connecting flange 326. 7. The two snap-fit ​​protrusions 421 are respectively snapped into the two snap-fit ​​notches 327. The two mounting parts 42 have relatively protruding limiting protrusions 422 on their opposite sides. There is a gap between the two limiting protrusions 422. The width of the gap is smaller than the outer diameter of the pipe 23. The pipe 23 can be inserted from the side opening of the mounting notch 33 and pass through the gap between the two limiting protrusions 422 to be tightly fitted into the clamping port 41 of the clamping block 4. When the top core 2 is pressed into the valve body 1 and the limiting plane 324 abuts against the upper end surface of the top core 2, the pipe 23 is inserted vertically into the clamping port 41, that is, the clamping block 4 is tightly clamped on the outer wall of the pipe 23.
