Description

A type of wine dispensing tap Technical Field

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

[0002] In order to draw out the wine from the barrel, traditional wine barrels usually have a spout at the barrel opening. The wine tap generally consists of a valve body and a connecting component connected to the valve body. The valve body is connected to the spout via the connecting component. When the wine flows out, high-pressure carbon dioxide gas enters the barrel, so that when the wine tap is opened, the wine in the barrel flows out through the spout and the wine tap in sequence under high pressure.

[0003] Traditional beer kegs are inconvenient and costly to use due to the need to connect to a carbon dioxide cylinder. Therefore, beer kegs that do not require a carbon dioxide cylinder and allow the beer to flow out automatically under gravity, along with matching dispensing valves, have emerged on the market. For example, a beer keg dispensing valve disclosed in Chinese patent literature (authorization announcement number: CN2260931Y) includes a gas-liquid distribution valve body with a spiral boss and a valve core top post at its front end. An air inlet channel and a beer outlet channel are respectively provided on both sides of the gas-liquid distribution valve body. The air inlet end of the air inlet channel is connected to an air inlet valve, and the air inlet channel passes through the valve core top post and connects to a straw inside the beer keg. One end of the beer outlet channel is connected to the beer outlet, and the other end outlet is located on the outer side of the middle of the spiral boss's flat surface and communicates with the inner cavity of the beer keg through a side hole of the dispensing valve body. This beer keg dispensing valve has the following shortcomings in use:

[0004] 1. Beer kegs contain beer, and during transportation and storage, they are usually placed upright. However, when used, the keg needs to be inverted to dispense the beer. Although the inside of the straw is isolated from the beer after inversion, some beer inevitably remains in the straw. Therefore, when the air intake is opened, the beer in the straw flows in from the outlet of the air intake and eventually flows out through the inlet end of the air intake valve, resulting in beer waste. The only way to avoid waste is to place a glass under the air intake valve to catch the beer flowing out of the air intake the first time the keg is used after inversion, but this method would be inconvenient.

[0005] 2. The gas-liquid distribution valve body is equipped with an air inlet valve and a beer outlet valve on both sides. When dispensing beer, the air inlet valve and the beer outlet valve need to be opened separately. When dispensing beer, not only does the beer outlet valve need to be closed, but the air inlet valve also usually needs to be closed to prevent the beer from being in contact with external gas for a long time, which would affect the taste and shelf life of the beer. This repeated operation of the air inlet valve and the beer outlet valve makes the operation quite troublesome. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems with existing technologies by proposing a wine dispensing tap. This invention solves the problems of existing wine dispensing taps causing wine waste and being cumbersome to operate.

[0007] The objective of this invention can be achieved through the following technical solution: A wine dispensing tap, comprising an air inlet pipe, a wine outlet pipe, and a connecting assembly, characterized in that the air inlet pipe and the wine outlet pipe are arranged side by side to form a valve body of the wine dispensing tap, one end of the valve body is bent downwards to form an L-shape and the downwardly bent portion forms the valve nozzle of the valve body, the other end of the valve body is connected to the connecting assembly, the air inlet of the air inlet pipe and the wine outlet of the wine outlet pipe are both located on the valve nozzle, the bent portion of the valve body has a valve core mounting hole one and a valve core mounting hole two, the valve core mounting hole one is provided with an air inlet valve core that can block the air inlet pipe, the valve core mounting hole two is provided with a wine outlet valve core that can block the wine outlet pipe, this wine dispensing tap also includes a linkage component, the air inlet valve core and the wine outlet valve core are both connected to the linkage component and both form a limit with the linkage component in the axial direction, the valve body is also provided with a tap switch that cooperates with the linkage component, the tap switch can drive the air inlet valve core and the wine outlet valve core to move axially simultaneously through the linkage component.

[0008] This dispensing tap is installed on a wine barrel, which includes a barrel body. A wine spear is fixed inside the barrel's opening, and a venting pipe is fixedly connected to the wine spear inside the barrel. The dispensing tap is connected to the wine spear via a connecting assembly, allowing the tap's inlet pipe to connect to the venting pipe inside the barrel, while the outlet pipe connects to the inner cavity of the barrel body. During transportation and storage, the barrel is generally placed upright. In use, the barrel is first inverted and placed on a barrel support. Then, the tap is turned on, ensuring both the inlet and outlet pipes are open. At this point, external gas can enter the barrel sequentially through the inlet and outlet pipes, maintaining pressure balance between the barrel and the outside environment to prevent negative pressure. The wine inside then flows out through the outlet pipe under gravity for consumption.

[0009] In this wine dispensing tap, the air inlet and wine outlet pipes are arranged side by side to form the valve body of the tap. One end of the valve body is bent downwards to form the valve nozzle, making the valve body L-shaped. The air inlet of the air inlet pipe and the wine outlet of the wine outlet pipe are both located on the valve nozzle, making the air inlet and wine outlet adjacent to each other. In this way, even if there is residual wine in the air inlet pipe when the wine barrel is inverted for the first time, because the wine glass is located below the wine outlet and the adjacent air inlet when receiving the wine, the residual wine in the air inlet will flow into the wine glass after flowing out of the air inlet. This way, the wine glass can be placed in the same position to receive the residual wine in the air inlet pipe and the wine flowing out of the wine outlet pipe, which is convenient to use and avoids the waste of wine.

[0010] Meanwhile, with the air inlet pipe and the wine outlet pipe arranged side by side, and by placing both valve core mounting holes one and two at the bends of the valve body, the air inlet valve core and the wine outlet valve core can also be made adjacent to each other. This allows the linkage to connect with both the air inlet valve core and the wine outlet valve core simultaneously. Since both the air inlet valve core and the wine outlet valve core are limited by the linkage in the axial direction, when the faucet switch is operated, the faucet switch can drive the air inlet valve core and the wine outlet valve core to move axially simultaneously through the linkage, so as to synchronously conduct the air inlet pipe and the wine outlet pipe, realizing dual control with one opening. This avoids the trouble of repeatedly operating the air inlet valve core and the wine outlet valve core separately, thus making the operation of this wine outlet faucet more convenient.

[0011] In the aforementioned dispensing tap, the air intake valve core includes an air intake valve rod slidably inserted into a valve core mounting hole one, and the dispensing valve core includes a dispensing valve rod slidably inserted into a valve core mounting hole two. The air intake valve rod and the dispensing valve rod are arranged adjacent to each other and parallel to each other. The adjacent and parallel arrangement of the air intake valve rod and the dispensing valve rod facilitates simultaneous connection of the linkage to both the air intake valve rod and the dispensing valve rod. Furthermore, this structure ensures that the movement directions of the air intake valve rod and the dispensing valve rod are parallel, which facilitates the synchronous movement of the air intake valve core and the dispensing valve core by the linkage, and improves the smoothness of their movement, making the operation of this dispensing tap more convenient and smooth.

[0012] In the aforementioned dispensing nozzle, the air inlet pipe includes a straight main air inlet pipe, and the dispensing pipe includes a straight main dispensing pipe. The bend in the valve body has a guide portion formed by the parallel arrangement of the ends of the main air inlet pipe and the main dispensing pipe. The port of the main air inlet pipe at the guide portion forms a valve core mounting hole one, and the port of the main dispensing pipe at the guide portion forms a valve core mounting hole two. This structure makes the air inlet pipe and the dispensing pipe a three-way connector, utilizing the port of the main air inlet pipe to form valve core mounting hole one and the port of the main dispensing pipe to form valve core mounting hole two, making manufacturing more convenient. Simultaneously, this structure ensures that the air inlet valve stem and the dispensing valve stem are parallel to each other, facilitating the synchronous movement of the air inlet valve core and the dispensing valve core by the linkage component.

[0013] In the aforementioned dispensing tap, the linkage component includes a sleeve portion slidably fitted onto a guide portion and a plate-shaped connecting portion located within the sleeve portion. One end of the air intake valve rod and one end of the dispensing valve rod are both engaged with the connecting portion. By providing a guide portion and slidably fitting the sleeve portion of the linkage component onto it, the movement of the linkage component can be guided, ensuring stable and precise movement. This, in turn, can stably drive the axial movement of the air intake valve rod and the dispensing valve rod, thereby better realizing dual control of the tap's opening and closing, and improving the stability and ease of use of the dispensing tap.

[0014] In the aforementioned dispensing faucet, the connecting part is provided with a first snap-fit ​​hole and a second snap-fit ​​hole. One end of the air intake valve rod and one end of the dispensing valve rod each have an annular groove. One end of the air intake valve rod passes through the first snap-fit ​​hole, and the edge of the first snap-fit ​​hole snaps into the annular groove of the air intake valve rod. One end of the dispensing valve rod passes through the second snap-fit ​​hole, and the edge of the second snap-fit ​​hole snaps into the annular groove of the dispensing valve rod. The thickness of the connecting part is slightly less than the width of the annular groove. Due to manufacturing and installation errors, during the axial movement of the air intake valve rod and the dispensing valve rod driven by the linkage, there may be situations where the air intake valve rod has moved into position and blocked the air intake pipe, while the dispensing valve rod has not yet moved into position and has not blocked the dispensing pipe. At this point, by making the thickness of the connecting part slightly smaller than the width of the annular groove, the linkage will not jam even when the air intake valve rod stops moving. Instead, it can still drive the dispensing valve rod to move a certain distance, ensuring that both the air intake valve rod and the dispensing valve rod can move into place to seal the air intake pipe and the dispensing pipe. Therefore, this structure can better achieve dual control of the faucet switch, improving the sealing performance, stability, and ease of use of the dispensing faucet.

[0015] In the aforementioned dispensing tap, the tap switch is a rotary cap, axially fixed and rotatably connected to the valve body. The linkage is located inside the tap switch. The outer peripheral wall of the sleeve portion of the linkage has a spirally extending groove, and the inner peripheral wall of the tap switch has a protrusion that matches and is embedded in the spiral groove. This structure utilizes the principle of threaded connection, matching and embedding the protrusion on the tap switch into the spiral groove of the linkage. By rotating the tap switch clockwise or counterclockwise, the linkage moves back and forth, thereby causing the air intake valve rod and the dispensing valve rod to move axially back and forth, ultimately achieving the blocking or opening of the air intake pipe and the dispensing pipe.

[0016] In addition to the rotary cap structure, the faucet switch can also adopt a handle structure. Specifically, the handle is hinged to the outer wall of the valve body. By moving the handle forward or backward, the lower end of the handle can change position, thereby pushing the linkage outward. This causes the linkage to drive the air intake valve rod and the wine outlet valve rod to move axially outward, thus connecting the air intake pipe and the wine outlet pipe. When wine is not needed, the linkage is reset under the action of the spring, which in turn drives the air intake valve rod and the wine outlet valve rod to move axially inward, blocking the air intake pipe and the wine outlet pipe.

[0017] In the aforementioned dispensing faucet, the end face of the guide portion has a limiting clip, and the inner circumferential wall of the sleeve portion has a guide groove parallel to the axial line of the sleeve portion. The end of the guide groove away from the connecting portion has a limiting surface. The limiting clip is slidably disposed within the guide groove. When the linkage moves outward relative to the guide portion, the limiting clip abuts against the limiting surface. The limiting clip has two functions: first, through the cooperation between the limiting clip and the guide groove, it guides the movement of the linkage, ensuring stable movement and thus better driving the air intake valve core and the dispensing valve rod to move axially; second, through the abutment between the limiting clip and the limiting surface, it prevents the linkage from detaching from the valve body after installation, thereby facilitating the assembly of the faucet switch and making product assembly and manufacturing more convenient.

[0018] In the aforementioned dispensing nozzle, a clearance hole is provided on the connecting part of the linkage component. When the linkage component moves inward relative to the guide part, the end of the limiting clip can extend into the clearance hole. During the inward movement of the linkage component, the end of the limiting clip extending into the clearance hole can prevent the limiting clip from contacting the linkage component. In addition, when it is necessary to disassemble the linkage component, the clearance hole can also allow a rod-shaped tool, such as a screwdriver, to be inserted. By pressing the limiting clip downward with the tool, the protrusion on the limiting clip can be misaligned with the limiting surface, thereby realizing the disassembly of the linkage component, and the disassembly is relatively convenient.

[0019] In the aforementioned wine dispensing nozzle, both the other end of the air intake valve stem and the other end of the wine dispensing valve stem are connected to rubber caps. The inner circumferential wall of the main air intake pipe has an annular step one, and the inner circumferential wall of the main wine dispensing pipe has an annular step two. The rubber cap of the air intake valve stem can abut against the annular step one to block the main air intake pipe. By axially moving the air intake valve stem away from the annular step one, the rubber cap can be disengaged from the annular step one, and the main air intake pipe can be connected to the air outlet. Similarly, the rubber cap of the wine dispensing valve stem can abut against the annular step two to block the main wine dispensing pipe. By axially moving the wine dispensing valve stem away from the annular step two, the rubber cap can be disengaged from the annular step two, and the main wine dispensing pipe can be connected to the wine outlet. This structure allows the intake valve stem and the dispensing valve stem to block or open the intake and dispensing pipes simply by axial back-and-forth movement. This eliminates the need for complex movement trajectories in the linkage components; a simple back-and-forth translation is sufficient to synchronously move the intake and dispensing valve stems axially. This makes the dispensing tap easy to operate with dual control and provides good stability, making it more convenient to use. The rubber cap abutting against the first and second annular stepped surfaces enhances the sealing effect, thereby improving the tap's sealing performance.

[0020] In the aforementioned dispensing nozzle, the connecting assembly includes a plug and snap-fit ​​strips symmetrically arranged on both sides of the plug. The plug has a gas channel communicating with an air inlet pipe and a liquid channel communicating with a dispensing pipe. The plug is inserted into the dispensing spout, and the snap-fit ​​strips can snap onto the outer wall of the dispensing spout to install the connecting assembly on the spout. After the dispensing nozzle is installed, the air inlet pipe is connected to the air guide pipe inside the barrel through the gas channel, and the dispensing pipe is connected to the inner cavity of the barrel through the liquid channel.

[0021] Compared with existing technologies, this wine-dispensing tap has the following advantages:

[0022] 1. In this wine dispensing tap, the air inlet and wine outlet pipes are arranged side by side to form the valve body of the dispensing tap, and the air inlet and wine outlet are adjacent to each other. In this way, even if there is residual wine in the air pipe when the wine barrel is inverted for the first time, because the wine glass is located below the wine outlet and the adjacent air inlet when receiving wine, the residual wine in the air pipe will also flow into the wine glass after flowing out of the air inlet. In this way, the wine glass can be placed in the same position to receive the residual wine in the air pipe and the wine flowing out of the wine outlet, which is convenient to use and can avoid the waste of wine.

[0023] 2. When the tap is operated, the tap can simultaneously drive the air inlet valve core and the wine outlet valve core to move axially through the linkage, so as to synchronously open the air inlet pipe and the wine outlet pipe, realizing dual control with one opening. This avoids the trouble of repeatedly operating the air inlet valve core and the wine outlet valve core separately, thus making the operation of this tap more convenient. Attached Figure Description

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0040] Example 1

[0041] As shown in Figures 1 to 4, this wine dispensing tap includes an air inlet pipe 1a, a wine outlet pipe 1b, and a connecting assembly 2. The air inlet pipe 1a and the wine outlet pipe 1b are arranged side by side to form the valve body 1 of the wine dispensing tap. One end of the valve body 1 is bent downwards, making the valve body 1 L-shaped, and the downward-bent part forms the valve nozzle 1c of the valve body 1. The other end of the valve body 1 is connected to the connecting assembly 2. The air inlet 1d of the air inlet pipe 1a and the wine outlet 1e of the wine outlet pipe 1b are both located on the valve nozzle 1c. The bent part of the valve body 1 has a valve core mounting hole 1f and a... The valve core mounting hole 1g is a second valve core mounting hole. The valve core mounting hole 1f is equipped with an intake valve core 3 that can block the intake pipe 1a. The valve core mounting hole 1g is equipped with a dispensing valve core 4 that can block the dispensing pipe 1b. This dispensing faucet also includes a linkage 5. The intake valve core 3 and the dispensing valve core 4 are both connected to the linkage 5 and are both limited by the linkage 5 in the axial direction. The valve body 1 is also equipped with a faucet switch 6 that cooperates with the linkage 5. The faucet switch 6 can drive the intake valve core 3 and the dispensing valve core 4 to move axially at the same time through the linkage 5.

[0042] As shown in Figures 2 and 13, the connecting component 2 includes a plug 21 and snap-fit ​​strips 22 symmetrically arranged on both sides of the plug 21. The plug 21 has a gas channel 23 connected to the air inlet pipe 1a and a liquid channel 24 connected to the wine outlet pipe 1b. The plug 21 is inserted into the wine spear 9, and the snap-fit ​​strips 22 can snap onto the outer wall of the wine spear 9 to realize the installation of the connecting component 2 on the wine spear 9. After the wine outlet is installed, the air inlet pipe 1a is connected to the air guide pipe 10 inside the barrel body 11 through the gas channel 23, and the wine outlet pipe 1b is connected to the inner cavity of the barrel body 11 through the liquid channel 24.

[0043] Furthermore, as shown in Figure 3, the intake valve core 3 includes an intake valve rod 31 slidably inserted into the valve core mounting hole 1f, and the outlet valve core 4 includes an outlet valve rod 41 slidably inserted into the valve core mounting hole 1g. The intake valve rod 31 and the outlet valve rod 41 are arranged adjacently and parallel to each other. The adjacent and parallel arrangement of the intake valve rod 31 and the outlet valve rod 41 facilitates the simultaneous connection of the linkage 5 with both the intake valve rod 31 and the outlet valve rod 41. This structure also ensures that the moving directions of the intake valve rod 31 and the outlet valve rod 41 are parallel, thus facilitating the synchronous movement of the intake valve core 3 and the outlet valve core 4 by the linkage 5.

[0044] As shown in Figure 3, rubber caps 8 are connected to the other end of the intake valve stem 31 and the other end of the outlet valve stem 41. The inner peripheral wall of the intake main pipe 1a1 has an annular step 1a2, and the inner peripheral wall of the outlet main pipe 1b1 has an annular step 2b2. The rubber cap 8 of the intake valve stem 31 can abut against the annular step 1a2 to block the intake main pipe 1a1. By moving the intake valve stem 31 axially away from the annular step 1a2, the rubber cap 8 can be disengaged from the annular step 1a2, and the intake main pipe 1a1 can be connected to the outlet. Similarly, the rubber cap 8 of the outlet valve stem 41 can abut against the annular step 2b2 to block the outlet main pipe 1b1. By moving the outlet valve stem 41 axially away from the annular step 2b2, the rubber cap 8 can be disengaged from the annular step 2b2, and the outlet main pipe 1b1 can be connected to the outlet 1e.

[0045] As shown in Figures 6 to 8, the air intake pipe 1a includes a straight air intake main pipe 1a1, and the wine outlet pipe 1b includes a straight wine outlet main pipe 1b1. The bend in the valve body 1 has a guide portion 1h formed by the ends of the air intake main pipe 1a1 and the wine outlet main pipe 1b1 arranged side-by-side. The port of the air intake main pipe 1a1 at the guide portion 1h forms a valve core mounting hole 1f, and the port of the wine outlet main pipe 1b1 at the guide portion 1h forms a valve core mounting hole 1g. This structure makes the air intake pipe 1a and the wine outlet pipe 1b a three-way pipe structure, utilizing the port of the air intake main pipe 1a1 to form the valve core mounting hole 1f and the port of the wine outlet main pipe 1b1 to form the valve core mounting hole 1g, making manufacturing more convenient.

[0046] As shown in Figure 3, the linkage 5 includes a sleeve portion 51 slidably sleeved on the guide portion 1h and a sheet-like connecting portion 52 located inside the sleeve portion 51. One end of the air intake valve rod 31 and one end of the wine outlet valve rod 41 are both engaged with the connecting portion 52. Specifically, the connecting portion 52 has a first engaging hole 53 and a second engaging hole 54. One end of the air intake valve rod 31 and one end of the wine outlet valve rod 41 both have annular grooves 7. One end of the air intake valve rod 31 passes through the first engaging hole 53 and the edge of the first engaging hole 53 is engaged in the annular groove 7 of the air intake valve rod 31. One end of the wine outlet valve rod 41 passes through the second engaging hole 54 and the edge of the second engaging hole 54 is engaged in the annular groove 7 of the wine outlet valve rod 41. The thickness t of the connecting portion 52 is slightly smaller than the width b of the annular groove 7.

[0047] As shown in Figures 9 and 12, the faucet switch 6 is a rotary cap, which is axially fixed and circumferentially rotatable to the valve body 1. The linkage 5 is located inside the faucet switch 6. The outer peripheral wall of the sleeve portion 51 of the linkage 5 has a spirally extending spiral groove 55, and the inner peripheral wall of the faucet switch 6 has a protrusion 61 that is matched and embedded in the spiral groove 55. This structure utilizes the principle of threaded connection to match and embed the protrusion 61 on the faucet switch 6 into the spiral groove 55 of the linkage 5. By rotating the faucet switch 6 clockwise or counterclockwise, the linkage 5 is driven to move back and forth, thereby driving the air intake valve rod 31 and the wine outlet valve rod 41 to move axially back and forth, ultimately achieving the blocking or opening of the air intake pipe 1a and the wine outlet pipe 1b.

[0048] As shown in Figures 5, 9, 10, and 11, the end face of the guide portion 1h has a limiting head 1i, and the inner peripheral wall of the sleeve portion 51 has a guide groove 56 parallel to the axial line of the sleeve portion 51. The end of the guide groove 56 away from the connecting portion 52 has a limiting surface 57. The limiting head 1i is slidably disposed in the guide groove 56. When the linkage 5 moves outward relative to the guide portion 1h, the limiting head 1i can abut against the limiting surface 57. The connecting portion 52 of the linkage 5 is also provided with a clearance hole 58. When the linkage 5 moves inward relative to the guide portion 1h, the end of the limiting head 1i can extend into the clearance hole 58.

[0049] As shown in Figure 13, this dispensing tap is installed on a wine barrel. The barrel includes a barrel body 11, with a wine spear 9 fixed inside the opening of the barrel body 11. A venting pipe 10 is fixedly connected to the wine spear 9 inside the barrel body 11. The dispensing tap is connected to the wine spear 9 via a connecting assembly 2. The inlet pipe 1a of the dispensing tap is connected to the venting pipe 10 inside the barrel body 11, while the outlet pipe 1b is connected to the inner cavity of the barrel body 11. During transportation and storage, the barrel is generally placed upright. When in use, the barrel is first inverted and placed on a barrel support (not shown in the figure). Then, the tap switch 6 is turned on, so that both the inlet pipe 1a and the outlet pipe 1b are open. At this time, external gas can enter the barrel sequentially through the inlet pipe 1a and the venting pipe 10, ensuring that the pressure inside the barrel is balanced with the external pressure and preventing negative pressure. The wine inside the barrel then flows out through the outlet pipe 1b for drinking. Since the air inlet 1d and the wine outlet 1e are adjacent, even if there is residual wine in the air duct 10 when the barrel is inverted for the first time, the wine glass is located below the wine outlet 1e and the adjacent air inlet 1d when receiving the wine. Therefore, the residual wine in the air duct 10 will flow into the wine glass after flowing out of the air inlet 1d. This allows the wine glass to be placed in the same position to receive the residual wine in the air duct 10 and the wine flowing out of the wine outlet 1b, which is convenient to use and avoids the waste of wine.

[0050] Example 2

[0051] This embodiment is basically the same as the first embodiment in terms of structure and principle. The difference is that, as shown in Figure 14, in addition to the rotating cap structure, the faucet switch 6 can also adopt a handle 12 structure. Specifically, the handle 12 is hinged to the outer wall of the valve body 1. By moving the handle 12 forward or backward, the lower end of the handle 12 can change position, thereby pushing the linkage 5 outward. This causes the linkage 5 to drive the air intake valve rod 31 and the wine outlet valve rod 41 to move axially outward, so that the air intake pipe 1a and the wine outlet pipe 1b are connected. When wine is not needed, the linkage 5 is reset under the action of the spring, thereby driving the air intake valve rod 31 and the wine outlet valve rod 41 to move axially inward, blocking the air intake pipe 1a and the wine outlet pipe 1b.
