The end of the cap is provided with a third axial hole that communicates with the third radial hole.

[0003] The aforementioned dispensing valve addresses some shortcomings in existing technologies, but it still has some drawbacks in practical use. For example, after dispensing the wine, the inner cylinder must be manually pushed completely back into the outer cylinder. This operation relies on manual intervention, which carries the potential risk of incomplete repositioning of the inner cylinder due to operational negligence. This could lead to sealing failure or wine leakage, affecting safety and hygiene standards.

[0004] Therefore, a rotary sliding wine dispensing valve is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a rotary sliding wine dispensing valve, thereby solving or at least alleviating one or more of the aforementioned problems and other issues existing in the prior art.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Please refer to Figures 1 to 3As shown, an embodiment of this utility model provides a rotary sliding wine dispensing valve, including an outer cylinder 1, an inner cylinder 2, and a first sealing sleeve 3. The outer cylinder 1 is tubular, and the inner cylinder 2 is slidably disposed inside the outer cylinder 1. The outer cylinder 1 has a first through hole 101, and the inner cylinder 2 has a second through hole 201. A plunger 4 is rotatably connected to the end of the inner cylinder 2 away from the second through hole 201. The plunger 4 is tubular, and an end cap is formed at one end of the plunger 4. A fourth through hole 401 is formed on the plunger 4. A third through hole 202 is formed at the end of the inner cylinder 2 near the plunger 4. A sliding groove 103 is formed at the end of the outer cylinder 1 away from the plunger 4. An annular protrusion 206 is formed at the end of the inner cylinder 2 away from the plunger 4. The annular protrusion 206 is slidably disposed in the sliding groove 103. A first spring 6 is sleeved on the inner cylinder 2. One end of the first spring 6 abuts against one end of the sliding groove 103, and the other end of the first spring 6 abuts against one side of the annular protrusion 206.

[0027] When it is time to dispense wine, pull the inner cylinder 2 outward. The inner cylinder 2 overcomes the elastic force of the first spring 6 and slides within the sliding groove 103, connecting the first through hole 101 with the second through hole 201. Wine enters the inner cylinder 2 from the first through hole 101 of the outer cylinder 1 through the second through hole 201. Rotate the plunger 4 to connect the fourth through hole 401 with the third through hole 202, and wine flows out through the third through hole 202 and the fourth through hole 401. After dispensing, release the inner cylinder 2. The elastic force of the first spring 6 returns the inner cylinder 2 to its original position, and the first through hole 101 and the second through hole 201 are misaligned, stopping the dispensing of wine.

[0028] Among them, the first spring 6 is a rubber-metal helical composite spring.

[0029] The rubber-metal helical composite spring combines the damping properties of rubber with the elasticity of a metal spring. During the operation of the rotary sliding wine dispensing valve, when the inner cylinder 2 slides, the rubber part can absorb vibration and impact, reducing noise, while the metal spring part provides stable elasticity, ensuring the return function of the inner cylinder 2. Moreover, it is made of silicone rubber, so it will not contaminate the wine.

[0030] In this embodiment, an assembly groove 104 is provided inside the outer cylinder 1 near the plunger 4. A second spring 7 and a movable plate 8 are provided inside the assembly groove 104. The movable plate 8 is slidably disposed in the assembly groove 104. One end of the second spring 7 abuts against the end of the assembly groove 104 away from the inner cylinder 2, and the other end of the second spring 7 abuts against one end of the movable plate 8. A limit rod 9 is fixedly connected to the end of the movable plate 8 away from the second spring 7. A locking groove 205 is provided on the outer wall of the inner cylinder 2, and the limit rod 9 can be inserted into the locking groove 205.

[0031] When the inner cylinder 2 is pulled outward to a certain position, the locking groove 205 moves to the position of the limiting rod 9. The second spring 7 pushes the movable plate 8, causing the limiting rod 9 to engage in the locking groove 205, locking the inner cylinder 2 in the dispensing position. At this time, the inner cylinder 2 can be released, ensuring that the dispensing process will not be interrupted or leaked due to accidental movement of the inner cylinder 2. When it is necessary to close the rotary sliding dispensing valve, a certain external force is applied to overcome the elasticity of the second spring 7, causing the limiting rod 9 to disengage from the locking groove 205, and the inner cylinder 2 returns to its original position under the action of the first spring 6.

[0032] In this embodiment, a guide groove 105 is provided at the end of the outer cylinder 1 away from the plunger 4. The guide groove 105 is connected to the sliding groove 103. A limiting slider 207 is fixedly connected to the annular protrusion 206, and the limiting slider 207 is slidably disposed within the guide groove 105. The limiting slider 207 slides within the guide groove 105, providing guidance for the sliding of the inner cylinder 2, ensuring that the inner cylinder 2 will not deviate or shake during the sliding process, and ensuring that the first through hole 101 and the second through hole 201 are accurately aligned.

[0033] In this embodiment, a first sealing groove 102 is formed on the inner wall of the outer cylinder 1, and a first sealing sleeve 3 is fixedly installed in the first sealing groove 102. A first connecting hole 301 is formed on the first sealing sleeve 3, and the first connecting hole 301 is connected to the first through hole 101. The first sealing sleeve 3 is installed in the first sealing groove 102 to play a sealing role and prevent the wine from leaking from the gap between the outer cylinder 1 and the inner cylinder 2. The first connecting hole 301 is connected to the first through hole 101 to ensure that the wine can smoothly enter the inner cylinder 2 from the first through hole 101.

[0034] In this embodiment, a second sealing groove 203 is formed on the inner wall of the inner cylinder 2, and a second sealing sleeve 5 is fixedly installed in the second sealing groove 203. The second sealing sleeve 5 has a second connecting port 501 that communicates with the third through hole 202. The second sealing sleeve 5 is installed in the second sealing groove 203 to prevent the wine from leaking from the gap between the inner cylinder 2 and the plunger 4. The second connecting port 501 communicates with the third through hole 202 to ensure that the wine can smoothly enter the plunger 4 from the inner cylinder 2 through the third through hole 202.

[0035] The inner cylinder 2 has an arc-shaped limiting groove 204 on its inner wall, and a limiting block 402 is formed at one end of the plunger 4 near the outer cylinder 1. The limiting block 402 is rotatably positioned within the arc-shaped limiting groove 204. When the plunger 4 is rotated, the limiting block 402 rotates within the arc-shaped limiting groove 204. The arc-shaped limiting groove 204 restricts the rotation range of the limiting block 402, thereby limiting the rotation angle of the plunger 4. This ensures that the fourth through hole 401 and the third through hole 202 can be accurately aligned and offset, avoiding excessive rotation that could lead to seal failure.

[0036] In this embodiment, a sealing plug 10 is installed at the end of the outer cylinder 1 away from the plunger 4, and the sealing plug 10 plays a sealing role.

[0037] Working principle:

[0038] Open the rotary sliding wine dispensing valve:

[0039] Pulling the inner cylinder 2 outward causes it to slide in the sliding groove 103, overcoming the elastic force of the first spring 6. At the same time, the limiting slider 207 slides in the guide groove 105, providing guidance for the inner cylinder 2.

[0040] When the inner cylinder 2 is pulled to a certain position, the locking groove 205 moves to the position of the limiting rod 9, and the second spring 7 pushes the movable plate 8, so that the limiting rod 9 is locked into the locking groove 205, locking the inner cylinder 2 in the wine-filling position. At this time, the first through hole 101 and the second through hole 201 are connected through the first connecting hole 301 on the first sealing sleeve 3, and the wine enters the second through hole 201 of the inner cylinder 2 from the first through hole 101 of the outer cylinder 1.

[0041] Rotate the plunger 4, and the limiting block 402 rotates in the arc-shaped limiting groove 204, so that the fourth through hole 401 and the third through hole 202 are connected through the second connection port 501 on the second sealing sleeve 5, and the wine flows out from the inner cylinder 2 through the third through hole 202 and the fourth through hole 401.

[0042] Close the rotary sliding wine dispensing valve:

[0043] Rotate the plunger 4 in the opposite direction to displace the fourth through hole 401 from the third through hole 202, thus stopping the dispensing of wine.

[0044] Apply a certain external force to overcome the elastic force of the second spring 7, so that the limiting rod 9 is disengaged from the locking groove 205.

[0045] The elastic force of the first spring 6 causes the inner cylinder 2 to return to its original position, and the first through hole 101 and the second through hole 201 are misaligned, stopping the wine from flowing in.
