Description

Technical Field

[0001] This utility model 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 and a tap connected to the spout at the mouth of the barrel. When the wine flows out, high-pressure carbon dioxide gas enters the barrel, so that when the tap is opened, the wine in the barrel flows out through the spout and the tap in sequence under high pressure.

[0003] To reduce production costs and improve ease of use, beer kegs that allow liquid to flow automatically under gravity without the need for a carbon dioxide cylinder, along with matching dispensing valves, have begun to appear on the market. For example, Chinese patent literature discloses a beer keg dispensing valve (authorization announcement number: CN2260931Y), which includes a gas-liquid distribution valve body with a spiral boss and a beer valve core top post at its front end. The feature is that an air inlet channel and a beer dispensing 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 the air inlet valve, and the air inlet channel passes through the beer valve core top post and is connected to the straw inside the beer keg. One end of the beer dispensing channel is connected to the beer outlet, and the other end of the outlet is located on the outer side of the middle of the horizontal plane of the spiral boss, and is connected to the inner cavity of the beer keg through the side hole of the beer spear body.

[0004] The beer keg dispensing valve has the following shortcomings during use: The gas-liquid distribution valve body of the beer keg dispensing valve has an inlet valve and a dispensing valve on each side. When dispensing beer, the inlet valve and the dispensing valve must be opened sequentially. When dispensing is not needed, not only the dispensing valve but also the inlet valve must be closed to prevent external gases from prolonged contact with the beer inside the keg, which could affect the beer's taste and shelf life. This repeated, separate operation of the inlet and dispensing valves makes the beer keg dispensing valve cumbersome and provides a poor user experience. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems with existing technologies by proposing a wine dispensing tap. The technical problem this invention aims to solve is the cumbersome operation of existing wine dispensing taps.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A wine dispensing tap includes a tap body with a gas pipe and a liquid pipe. An inlet valve core and a outlet valve core are respectively installed inside the gas pipe and liquid pipe. The lower side of the tap body has an inlet nozzle and an outlet nozzle respectively connected to the gas pipe and liquid pipe. The tap body is characterized by having a first sealing surface on its inner circumferential wall that forms a seal with the inlet valve core, and a second sealing surface on the inner circumferential wall of the liquid pipe that forms a seal with the outlet valve core. A linkage is provided on the tap body. Both the inlet valve core and the outlet valve core are connected to the linkage and are axially limited by the linkage. The linkage can drive the inlet valve core and the outlet valve core to move axially and cause the inlet valve core to first disengage from the first sealing surface.

[0008] When using this dispensing tap, the user only needs to control the movement of the inlet valve core and the outlet valve core relative to the tap body via the linkage. Furthermore, the manufacturing process of the mating structure between the first sealing surface and the inlet valve core, and the second sealing surface and the outlet valve core, is simple, easy to process and fit, provides a stable and reliable seal, is convenient to install without requiring precise alignment, and is easier to clean and maintain. Specifically, since both the inlet valve core and the outlet valve core are connected to the linkage and both form a limiting relationship with the linkage in the axial direction, this allows the inlet valve core, which forms a sealing fit with the first sealing surface of the gas pipe, and the outlet valve core, which forms a sealing fit with the second sealing surface of the liquid pipe, to move axially with the linkage simultaneously or sequentially (allowing the inlet valve core to move axially). The connection method between the gas valve core, liquid outlet valve core, and linkage is more flexible, ultimately enabling the sequential connection of the gas pipeline and air inlet, as well as the liquid pipeline and liquid outlet. This allows the dispensing tap to first release gas and then release liquid, ensuring that the atmospheric pressure inside and outside the barrel is equalized before the liquid pipeline and liquid outlet are connected. This allows the liquid in the barrel to flow out of the dispensing tap's liquid pipeline under gravity and into the receiving glass through the liquid outlet, thus shortening the user's waiting time and improving the user experience. In addition, this dispensing tap only requires one linkage to control the movement of the air inlet valve core and the liquid outlet valve core, achieving dual control with one opening, making the dispensing tap more convenient to operate and solving the problem of cumbersome operation of existing dispensing taps.

[0009] In the aforementioned dispensing faucet, the air inlet valve core and the liquid outlet valve core are axially fixed to the linkage component. The air inlet valve core is provided with an air inlet sealing gasket that can form a sealing fit with the first sealing surface, and the liquid outlet valve core is provided with a liquid outlet sealing gasket that can form a sealing fit with the second sealing surface. Both the air inlet sealing gasket and the liquid outlet sealing gasket are capable of elastic deformation. By providing elastically deformable air inlet sealing gaskets and liquid outlet sealing gaskets on the air inlet valve core and the liquid outlet valve core, respectively, the sealing effect between the first sealing surface and the air inlet valve core, as well as between the second sealing surface and the liquid outlet valve core, can be improved, resulting in a better user experience.

[0010] In the above-mentioned wine dispensing faucet, the first sealing surface is a first annular step disposed on the inner wall of the gas pipe, and the second sealing surface is a second annular step disposed on the inner wall of the liquid pipe. When the gas pipe and the air inlet, as well as the liquid pipe and the liquid outlet, are all in a connected state, the distance between the air inlet sealing gasket and the first annular step is greater than the distance between the liquid outlet sealing gasket and the second annular step. By setting a first annular step on the inner wall of the gas pipeline to abut against and form a seal with the inlet gasket, and setting a second annular step on the inner wall of the liquid pipeline to abut against and form a seal with the outlet gasket, the inlet gasket on the inlet valve core can better cut off the gas pipeline and the inlet nozzle, and the outlet gasket on the outlet valve core can better cut off the liquid pipeline and the outlet nozzle. After the liquid is dispensed, when the outlet gasket and the second annular step have formed a seal, the inlet gasket will continue to move towards the first annular step to form a seal. During this process, the outlet gasket undergoes elastic deformation. On the one hand, this keeps the outlet gasket and the second annular step abutting and sealing, and on the other hand, the elastic deformation of the outlet gasket itself allows the inlet gasket to continue to move smoothly towards the first annular step to form a seal, thereby realizing the sequential connection between the gas pipeline and the inlet nozzle, and the liquid pipeline and the outlet nozzle.

[0011] In one of the above-mentioned dispensing faucets, the first annular step and the second annular step are positioned at the same location along the axial direction of the faucet body, and the liquid outlet sealing gasket and the air inlet sealing gasket are staggered front-to-back along the axial direction of the faucet body; or the liquid outlet sealing gasket and the air inlet sealing gasket are positioned at the same location along the axial direction of the faucet body, and the second annular step and the first annular step are staggered front-to-back along the axial direction of the faucet body. This allows the linkage to simultaneously drive the air inlet valve core and the liquid outlet valve core to move axially, and to cause the air inlet valve core to first disengage from the first sealing surface to connect the gas pipe and the air inlet nozzle.

[0012] In the aforementioned dispensing faucet, the first annular step and the second annular step are positioned at the same location along the axial direction of the faucet body, and the elastic deformation capacity of the air inlet sealing gasket is less than that of the liquid outlet sealing gasket. This allows the linkage to simultaneously drive the air inlet valve core and the liquid outlet valve core to move axially, and to cause the air inlet valve core to first disengage from the first sealing surface to connect the gas pipe and the air inlet nozzle.

[0013] In the above-mentioned wine dispensing faucet, the inner wall of the gas pipe and the inner wall of the air inlet facing the air inlet sealing gasket intersect to form a first flange, and the inner wall of the liquid pipe and the inner wall of the liquid outlet facing the liquid outlet sealing gasket intersect to form a second flange. When the gas pipe and the air inlet, as well as the liquid pipe and the liquid outlet, are all in a connected state, the distance between the air inlet sealing gasket and the first flange is greater than the distance between the liquid outlet sealing gasket and the second flange. In use, the user needs to connect the dispensing nozzle to the spout of the wine barrel. Because the distance between the air intake sealing gasket and the first flange on the air intake valve core is greater than the distance between the liquid outlet sealing gasket and the second flange on the liquid outlet valve core, the air intake sealing gasket passes the first flange towards the linkage earlier than the liquid outlet sealing gasket passes the second flange towards the linkage (when the liquid outlet sealing gasket passes the second flange towards the linkage, the liquid outlet sealing gasket and the second sealing surface separate to connect the liquid pipe and the liquid outlet nozzle; when the air intake sealing gasket passes the first flange towards the linkage, the air intake sealing gasket and the first sealing surface separate to connect the gas pipe and the air intake nozzle), thus enabling the air intake... The valve core and the liquid outlet valve core are connected sequentially to the gas pipeline and the air inlet, and the liquid pipeline and the liquid outlet, respectively. Similarly, the time when the liquid outlet sealing gasket crosses the second flange in the direction away from the linkage is earlier than the time when the air inlet sealing gasket crosses the first flange in the direction away from the linkage (when the liquid outlet sealing gasket crosses the second flange in the direction away from the linkage, the liquid outlet sealing gasket and the second sealing surface form a sealing fit so that the liquid outlet sealing gasket cuts off the liquid pipeline and the liquid outlet; when the air inlet sealing gasket crosses the first flange in the direction away from the linkage, the air inlet sealing gasket and the first sealing surface form a sealing fit so that the air inlet sealing gasket cuts off the gas pipeline and the air inlet), thereby realizing the sequential connection of the gas pipeline and the air inlet, and the liquid pipeline and the liquid outlet.

[0014] In the aforementioned dispensing faucet, the linkage is cylindrical and movably sleeved on the outside of the faucet body. The linkage has a first locking hole and a second locking hole. One end of the air inlet valve core and the liquid outlet valve core respectively has a first annular groove and a second annular groove. One end of the air inlet valve core passes through the first locking hole, and the edge of the first locking hole engages with the first annular groove of the air inlet valve core. One end of the liquid outlet valve core passes through the second locking hole, and the edge of the second locking hole engages with the second annular groove of the liquid outlet valve core. The difference between the width of the first annular groove and the thickness of the edge of the first locking hole is less than the difference between the width of the second annular groove and the thickness of the edge of the second locking hole. By making the difference between the width of the first annular groove and the thickness of the edge of the first locking hole less than the difference between the width of the second annular groove and the thickness of the edge of the second locking hole, the linkage can sequentially drive the air inlet valve core and the liquid outlet valve core to move axially, causing the air inlet valve core to first disengage from the first sealing surface to connect the gas pipe and the air inlet nozzle.

[0015] In the aforementioned dispensing faucet, a control knob that can rotate relative to the linkage is threadedly connected to the linkage component. The faucet body has a radially protruding limiting protrusion, and the control knob has an annular limiting groove. The limiting protrusion is embedded in the annular limiting groove. The faucet body has a limiting block, and the linkage component has a limiting hole. The limiting block extends into the limiting hole. Through the cooperative structure of the limiting block and the limiting hole, as well as the limiting protrusion and the annular limiting groove, the linkage component cannot rotate synchronously with the control knob, but can only move linearly. This better drives the air inlet valve core and the liquid outlet valve core to open and close the gas and liquid pipelines of the dispensing faucet.

[0016] In the aforementioned wine dispensing tap, both the gas and liquid pipes are tubular, with the liquid pipe having a larger diameter than the gas pipe. The air inlet and liquid outlet are arranged side-by-side on the lower side of the tap body. The smaller diameter of the gas pipe allows for a faster flow of external gas, while the larger diameter of the liquid pipe facilitates better wine dispensing. This combination ensures a smoother wine dispensing process. The side-by-side arrangement of the air inlet and liquid outlet on the lower side of the tap body allows a single glass to simultaneously receive the wine flowing from both the air inlet and outlet (the wine flowing from the air inlet is any wine accidentally introduced during the first use when the barrel was inverted). This also allows the wine to flow more effectively to the receiving glass under gravity and better collects any wine accidentally introduced into the air inlet, preventing waste and splashing, thus ensuring hygienic drinking and avoiding wine waste.

[0017] In the aforementioned dispensing tap, the tap body is equipped with a connector and symmetrically arranged locking strips on both sides of the connector. The connector has an outlet for gas and an inlet for liquid. The connector can be inserted into the dispensing spout, and after the dispensing tap is connected to the spout, it can push the spout open, allowing the gas and liquid channels of the dispensing tap to connect to the inlet and outlet channels of the spout, respectively. The locking strips can engage with the outer wall of the spout to better connect the dispensing tap to the barrel.

[0018] Compared with existing technologies, the advantages of this wine dispensing tap are as follows: This wine dispensing tap can achieve dual control with one opening. Users only need to control the air inlet valve core (including air inlet sealing gasket) and the liquid outlet valve core (including liquid outlet sealing gasket) to move synchronously or sequentially relative to the tap body through the linkage component. This can realize the sequential connection of the gas pipeline and air inlet, as well as the liquid pipeline and liquid outlet, which can shorten the user's waiting time for dispensing wine and make the wine dispensing tap more convenient to operate and provide a better user experience.

[0029] 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.

[0030] Example 1

[0031] A type of wine dispensing tap, as shown in the reference Figure 1-5 and Figure 8The faucet body 1 includes a gas pipe 1a and a liquid pipe 1b. An inlet valve core 2 and a liquid outlet valve core 3 are respectively installed inside the gas pipe 1a and the liquid pipe 1b. The lower side of the faucet body 1 has an inlet nozzle 1f and a liquid outlet nozzle 1j that are respectively connected to the gas pipe 1a and the liquid pipe 1b. The inner circumferential wall of the gas pipe 1a has a first sealing surface 1a1 that can form a sealing contact with the inlet valve core 2. The inner circumferential wall of the liquid pipe 1b has a second sealing surface 1b1 that can form a sealing contact with the liquid outlet valve core 3. A linkage 4 is provided on the faucet body 1. The inlet valve core 2 and the liquid outlet valve core 3 are both connected to the linkage 4 and are both limited in the axial direction by the linkage 4. The linkage 4 can drive the inlet valve core 2 and the liquid outlet valve core 3 to move axially and cause the inlet valve core 2 to first disengage from the first sealing surface 1a1, so as to first connect the gas pipe 1a and the inlet nozzle 1f.

[0032] Specifically, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 The air inlet valve core 2 and the liquid outlet valve core 3 are axially fixed to the linkage 4. The air inlet valve core 2 is provided with an air inlet sealing gasket 6 that can form a sealing fit with the first sealing surface 1a1. The liquid outlet valve core 3 is provided with a liquid outlet sealing gasket 7 that can form a sealing fit with the second sealing surface 1b1. Both the air inlet sealing gasket 6 and the liquid outlet sealing gasket 7 can undergo elastic deformation. The first sealing surface 1a1 is a first annular step provided on the inner wall of the gas pipe 1a. The second sealing surface 1b1 is a second annular step provided on the inner wall of the liquid pipe 1b. When the gas pipe 1a and the air inlet 1f, as well as the liquid pipe 1b and the liquid outlet 1j, are all in a connected state, the distance between the air inlet sealing gasket 6 and the first annular step is greater than the distance between the liquid outlet sealing gasket 7 and the second annular step.

[0033] More specifically, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8The linkage 4 is threadedly connected to a control knob 5 that can rotate relative to it. The faucet body 1 has a radially protruding limiting protrusion 1k. The control knob 5 has an annular limiting groove 5a. The limiting protrusion 1k is embedded in the annular limiting groove 5a. The faucet body 1 has a limiting block 1c. The linkage 4 has a limiting hole 4a. The limiting block 1c extends into the limiting hole 4a. The faucet body 1 is provided with a plug 1d and locking strips 1e symmetrically arranged on both sides of the plug 1d. The plug 1d has an air outlet 1g connected to the gas pipe 1a and a liquid inlet 1h connected to the liquid pipe 1b.

[0034] In this embodiment, both the gas pipe 1a and the liquid pipe 1b are preferably tubular, the diameter of the liquid pipe 1b is larger than the diameter of the gas pipe 1a, and the air inlet 1f and the liquid outlet 1j are arranged side by side on the lower side of the faucet body 1.

[0035] It should be noted that the preferred embodiments of this implementation include the following three types: the first annular step and the second annular step are positioned at the same location along the axial direction of the faucet body 1, and the liquid outlet sealing gasket 7 and the air inlet sealing gasket 6 are staggered front and back along the axial direction of the faucet body 1; or the liquid outlet sealing gasket 7 and the air inlet sealing gasket 6 are positioned at the same location along the axial direction of the faucet body 1, and the second annular step and the first annular step are staggered front and back along the axial direction of the faucet body 1; or the first annular step and the second annular step are positioned at the same location along the axial direction of the faucet body 1, and the elastic deformation capacity of the air inlet sealing gasket 6 is less than that of the liquid outlet sealing gasket 7.

[0036] The following explains the working principle of this wine tap:

[0037] In use, the user needs to insert the connector 1d of the dispensing nozzle into the wine spear on the wine barrel, and the locking strips 1e symmetrically arranged on both sides of the connector 1d can be locked onto the outer wall of the wine spear, thus connecting the dispensing nozzle and the wine spear. The connector 1d of the dispensing nozzle pushes open the wine spear, and the gas pipe 1a and liquid pipe 1b of the dispensing nozzle are respectively connected to the air inlet channel and liquid outlet channel of the wine spear. Then, the user rotates the control knob 5, which drives the linkage 4 to move away from the connector 1d. Since the limiting block 1c extends into the limiting hole 4a, the linkage 4 cannot rotate synchronously with the control knob 5, but can only move in a straight line. When the control knob 5 is rotated, the thread on the control knob 5 will pull the linkage 4 away from the connector 1d through the thread on the linkage 4 (similar to the working principle of a lead screw and nut).

[0038] When dispensing wine, because the distance between the air inlet sealing pad 6 on the air inlet valve core 2 and the first annular step is greater than the distance between the liquid outlet sealing pad 7 on the liquid outlet valve core 3 and the second annular step, both the air inlet sealing pad 6 and the liquid outlet sealing pad 7 can undergo elastic deformation. Therefore, the time when the air inlet sealing pad 6 separates from the first annular step is earlier than the time when the liquid outlet sealing pad 7 separates from the second annular step (when the air inlet sealing pad 6 separates from the first annular step, the gas pipe 1a and the air inlet 1f are connected; when the liquid outlet sealing pad 7 separates from the second annular step, the liquid pipe 1b and the liquid outlet 1j are connected), thus making the gas pipe 1a and the air inlet 1f of this wine dispensing tap connected before the liquid pipe 1b and the liquid outlet 1j.

[0039] When the wine is collected, because the distance between the air inlet sealing gasket 6 on the air inlet valve core 2 and the first annular step is greater than the distance between the liquid outlet sealing gasket 7 on the liquid outlet valve core 3 and the second annular step, the time when the air inlet sealing gasket 6 and the first annular step form a seal is later than the time when the liquid outlet sealing gasket 7 and the second annular step form a seal (when the air inlet sealing gasket 6 and the first annular step form a seal, the air inlet sealing gasket 6 cuts off the gas pipe 1a and the air inlet nozzle 1f; when the liquid outlet sealing gasket 7 and the second annular step form a seal, the liquid outlet sealing gasket 7 cuts off the liquid pipe 1b and the liquid outlet nozzle 1j), plus the air inlet sealing gasket 6... Both the sealing gasket 6 and the liquid outlet sealing gasket 7 can undergo elastic deformation. After the liquid outlet sealing gasket 7 and the second annular step have formed a contact seal, the air inlet sealing gasket 6 will continue to move towards the first annular step to form a contact seal. During this process, the liquid outlet sealing gasket 7 undergoes elastic deformation, which on the one hand keeps the liquid outlet sealing gasket 7 and the second annular step in contact seal, and on the other hand, through the elastic deformation of the liquid outlet sealing gasket 7 itself, the air inlet sealing gasket 6 can continue to move smoothly towards the first annular step to form a contact seal, thereby causing the liquid pipe 1b and the liquid outlet nozzle 1j to be cut off before the gas pipe 1a and the air inlet nozzle 1f.

[0040] Example 2

[0041] This embodiment is basically the same in structure and principle as Embodiment 1, the difference being: (Refer to...) Figure 1 , Figure 6-8 The inner wall of the gas pipe 1a and the inner wall of the inlet nozzle 1f facing the inlet sealing gasket 6 intersect to form a first flange portion 1l. The inner wall of the liquid pipe 1b and the inner wall of the outlet nozzle 1j facing the outlet sealing gasket 7 intersect to form a second flange portion 1m. When the gas pipe 1a and the inlet nozzle 1f, as well as the liquid pipe 1b and the outlet nozzle 1j, are all in a connected state, the distance between the inlet sealing gasket 6 and the first flange portion 1l is greater than the distance between the outlet sealing gasket 7 and the second flange portion 1m.

[0042] In this embodiment, the first and second annular steps are preferably omitted. Both the gas pipe 1a and the liquid pipe 1b are tubular, and the gas pipe 1a and the liquid pipe 1b are equidistant from each other along the inner diameter of the faucet body 1, so that the first sealing surface 1a1 and the second sealing surface 1b1 are located on the inner peripheral walls of the gas pipe 1a and the liquid pipe 1b, respectively.

[0043] Specifically, refer to Figure 1 , Figure 6-8 The air intake valve core 2 (including the air intake sealing gasket 6) and the liquid outlet valve core 3 (including the liquid outlet sealing gasket 7) move synchronously with the linkage 4. Since the distance between the air intake sealing gasket 6 and the first flange 11 on the air intake valve core 2 is greater than the distance between the liquid outlet sealing gasket 7 and the second flange 1m on the liquid outlet valve core 3, the time it takes for the air intake sealing gasket 6 to cross the first flange 11 towards the linkage 4 is earlier than the time it takes for the liquid outlet sealing gasket 7 to cross the second flange 1m towards the linkage 4. (When the liquid outlet sealing gasket 7 crosses the second flange 1m towards the linkage 4, the liquid pipe 1b and the liquid outlet 1j are connected; when the air intake sealing gasket 6 crosses the second flange 1m towards the linkage 4...) When passing the first flange 1l, the gas pipe 1a and the air inlet 1f are connected, so that the air inlet valve core 2 and the liquid outlet valve core 3 are connected to the gas pipe 1a and the air inlet 1f and the liquid pipe 1b and the liquid outlet 1j respectively. When the gas pipe 1a and the air inlet 1f are connected first, the outside gas will enter the gas pipe 1a through the air inlet 1f, and then enter the air inlet channel of the wine spear through the air outlet 1g and finally enter the wine barrel. This will make the atmospheric pressure inside and outside the wine barrel equal beforehand. Then the liquid pipe 1b and the liquid outlet 1j are connected, and the wine in the wine barrel flows out from the liquid pipe 1b of the wine tap under the action of gravity and flows into the wine glass through the liquid outlet 1j.

[0044] When the wine is dispensed, the user rotates the control knob 5 in the reverse direction. At this time, the control knob 5 drives the linkage 4 to move closer to the connector 1d. Simultaneously, the threads on the control knob 5 push the linkage 4 closer to the connector 1d via the threads on the linkage 4. The air intake valve core 2 and the liquid outlet valve core 3 move synchronously with the linkage 4. Because the distance between the air intake sealing gasket 6 and the first flange 1l on the air intake valve core 2 is greater than the distance between the liquid outlet sealing gasket 7 and the second flange 1m on the liquid outlet valve core 3, the time it takes for the liquid outlet sealing gasket 7 to cross the second flange 1m away from the linkage 4 is earlier than the time it takes for the air intake sealing gasket 6 to cross the first flange 1l away from the linkage 4. (When the liquid outlet sealing gasket 7 crosses the second flange 1m away from the linkage 4, the liquid outlet sealing gasket 7 and the second sealing surface 1b1 form a sealing fit.) The liquid outlet sealing gasket 7 cuts off the liquid pipe 1b and the liquid outlet nozzle 1j. When the air inlet sealing gasket 6 moves away from the linkage 4 and passes the first flange portion 1l, the air inlet sealing gasket 6 and the first sealing surface 1a1 form a sealing fit so that the air inlet sealing gasket 6 cuts off the gas pipe 1a and the air inlet nozzle 1f. This causes the liquid pipe 1b and the liquid outlet nozzle 1j, as well as the gas pipe 1a and the air inlet nozzle 1f, of the dispensing tap to be cut off in sequence. When the liquid pipe 1b and the liquid outlet nozzle 1j are cut off by the liquid outlet sealing gasket 7, the wine in the barrel no longer flows out from the liquid pipe 1b of the dispensing tap through the liquid outlet nozzle 1j. The gas pipe 1a and the air inlet nozzle 1f of this dispensing tap are connected before the liquid pipe 1b and the liquid outlet nozzle 1j. At the same time, the liquid pipe 1b and the liquid outlet nozzle 1j are cut off before the gas pipe 1a and the air inlet nozzle 1f, thereby shortening the user's waiting time for receiving wine and improving the user experience.

[0045] Example 3

[0046] This embodiment is basically the same in structure and principle as Embodiment 1 and Embodiment 2, except that: (Refer to...) Figure 9 The biggest difference between this embodiment and Embodiment 1 and Embodiment 2 is that in this embodiment, the linkage 4 can drive the air inlet valve core 2 and the liquid outlet valve core 3 to move axially in sequence, so that the gas pipeline 1a and the air inlet 1f and the liquid pipeline 1b and the liquid outlet 1j are connected in sequence (in Embodiment 1 and Embodiment 2, the linkage 4 preferably drives the air inlet valve core 2 and the liquid outlet valve core 3 to move axially at the same time).

[0047] Specifically, refer to Figure 9The linkage 4 is cylindrical and movably sleeved on the outside of the faucet body 1. The linkage 4 has a first locking hole 4b and a second locking hole 4c. One end of the air inlet valve core 2 and the liquid outlet valve core 3 respectively has a first annular groove 2a and a second annular groove 3a. One end of the air inlet valve core 2 passes through the first locking hole 4b and the edge of the first locking hole 4b is locked in the first annular groove 2a of the air inlet valve core 2. One end of the liquid outlet valve core 3 passes through the second locking hole 4c and the edge of the second locking hole 4c is locked in the second annular groove 3a of the liquid outlet valve core 3. The difference between the width of the first annular groove 2a and the thickness of the edge of the first locking hole 4b is less than the difference between the width of the second annular groove 3a and the thickness of the edge of the second locking hole 4c.

[0048] By making the difference between the width of the first annular groove 2a and the edge thickness of the first snap-fit ​​hole 4b smaller than the difference between the width of the second annular groove 3a and the edge thickness of the second snap-fit ​​hole 4c, when the gas pipe 1a and the air inlet 1f, as well as the liquid pipe 1b and the liquid outlet 1j are all in a cut-off state, the linkage 4 can drive the air inlet valve core 2 and the liquid outlet valve core 3 to move axially in sequence, so that the gas pipe 1a and the air inlet 1f, as well as the liquid pipe 1b and the liquid outlet 1j are connected sequentially.

[0049] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model.
