[0007] According to the technical solution provided in the embodiments of this application, the support is coaxially provided with an annular first partition plate and an annular second partition plate, a first space is formed inside the first partition plate, and the mounting part is disposed in the first space; a second space is formed between the second partition plate and the first partition plate, the guide part is a plurality of guide holes opened on the outer wall of the second partition plate and spaced apart, and the second space forms the guide path after the mounting cap is connected to the barrel.

[0008] According to the technical solution provided in the embodiments of this application, the outer side of the second partition plate is provided with a plurality of first support portions, the plurality of first support portions are spaced apart and the positions of the first support portions correspond one-to-one with the positions of the guide holes.

[0009] According to the technical solution provided in the embodiments of this application, the connecting pipe is provided with a snap-fit ​​section in the middle, the snap-fit ​​section is used to snap-fit ​​with the mounting part, one end of the connecting pipe is placed in the first space, and the other end extends out of the first space.

[0010] According to the technical solution provided in the embodiments of this application, the mounting part further includes a plurality of extensions, the plurality of extensions being arranged circumferentially around the mounting part and extending to the outside of the first space, and a second support part being provided on the outside of each extension.

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example 1 Please refer to Figures 1-5 This embodiment provides a wine spear, comprising: Support 1, the support 1 is provided with mounting part 2 and flow guide part 3 provided around the mounting part 2; Mounting cap 4 is detachably connected to the opening of the barrel. After connection, the support 1 is fixed at the opening of the barrel, and a guide passage 5 is formed inside the mounting cap 4. One end of the guide passage 5 is provided with an installation interface 6 that communicates with the outside, and the other end is connected to the guide part 3. The switching mechanism includes a connecting pipe 7 and a switching assembly 8. The connecting pipe 7 passes through the mounting part 2 and is fixed inside the mounting part 2, and is used to connect the guide passage 5 with the inside of the barrel. The switching assembly 8 includes a first state and a second state. When it is in the first state, it blocks the mounting interface 6 and the connecting pipe 7. When it is in the second state, it opens the mounting interface 6 and allows the connecting pipe 7 to communicate with the outside through the mounting interface 6.

[0021] Specifically, the support 1 is the basic supporting structure for the wine spear. It has an open top and an integrally formed mounting section 2 and a flow guide section 3. The flow guide section 3 surrounds the mounting section 2 and is used to cooperate with the flow guide path 5 to facilitate the flow of the wine. The mounting section 2 provides fixed support for the core component of the switching mechanism and extends through the bottom of the support 1. The outer edge of the support 1 has an overlapping protrusion for overlapping the opening of the wine barrel. The inner wall of the mounting cap 4 has internal threads, allowing for a detachable connection with the external threads at the opening of the wine barrel. When the mounting cap 4 is screwed into and fixed to the opening of the wine barrel, it will tightly press the support 1 against the end face of the opening, ensuring that the support 1 will not shift during the use of the wine barrel. Meanwhile, the interior of the mounting cap 4 is hollow, forming a flow path 5. One end of the flow path 5 extends through the top of the mounting cap 4, forming a mounting interface 6 for connecting with the dispensing equipment, while the other end connects to the guide section 3 on the support 1, ensuring a seamless connection between the flow path 5 and the guide section 3 to prevent liquid stagnation or leakage. Optionally, the dispensing equipment is a small dispenser. Preferably, the dispensing spear provided in this embodiment is suitable for 3-liter barrels.

[0022] The switching mechanism mainly consists of a connecting pipe 7 and a switching assembly 8. The connecting pipe 7 is a hollow tube that passes through the mounting part 2 along the axis of the support 1 and is fixed inside the mounting part 2 by a snap-fit ​​mechanism. One end of the connecting pipe 7 extends into the guide passage 5, and the other end extends into the inside of the barrel to allow gas flow and ensure smooth flow of the liquor. The switching assembly 8 has a switchable first state and a second state: when the liquor spout is in the non-use state (i.e., the first state), the switching assembly 8 will simultaneously block the ports of the mounting interface 6 and the connecting pipe 7, preventing the liquor in the barrel from flowing out and also preventing external dust and impurities from entering the barrel through the mounting interface 6. When a dispensing operation is required (i.e., the second state), the dispensing device installed at the mounting interface 6 extends into the mounting interface 6 and triggers the switch assembly 8 to open the mounting interface 6. At this time, one passage on the dispensing device is connected to the guide passage 5. The wine can then flow along the path of the inside of the barrel, the guide section 3, the guide passage 5, the mounting interface 6, and the dispensing device to achieve the dispensing of the wine. At the same time, another passage on the dispensing device connects the connecting pipe 7 to the external atmosphere, ensuring stable air pressure inside and outside the barrel, thereby ensuring the smooth flow of the wine.

[0023] Furthermore, the connecting pipe 7 has multiple flow guide ports 9 on one side wall near the mounting cap 4; the switch assembly 8 includes: A sealing element 10 is sleeved on the connecting pipe 7 and can slide relative to the connecting pipe 7. The elastic element 11 is sleeved on the mounting part 2, with one end abutting against the sealing element 10 and the other end installed at the position of the mounting part 2; the elastic element 11 is retractable along the extension direction of the connecting pipe 7. In its natural state, the elastic element 11 abuts against the sealing element 10 to block the mounting interface 6, and the inner wall of the sealing element 10 blocks the guide port 9.

[0024] Specifically, the connecting pipe 7 has multiple axially evenly spaced guide ports 9 on one side wall near the mounting cap 4, allowing for air pressure communication between the inside of the barrel and the mounting interface 6. The sealing element 10 is a cylindrical structure with one open end and one closed end. Its inner wall fits against the outer wall of the connecting pipe 7 and can slide relative to it along the axial direction of the connecting pipe 7. The closed end of the sealing element 10 can cover the mounting interface 6, while the open end faces the mounting part 2. The opening and closing of the mounting interface 6 and the guide ports 9 are achieved by sliding. The elastic element 11 is preferably a compression spring, which is sleeved on the outer periphery of the mounting part 2. One end of the elastic element 11 abuts against the end face of the open end of the sealing element 10, and the other end abuts against the mounting part 2 near the guide part 3. The extension and contraction direction of the elastic element 11 is consistent with the extension direction of the connecting pipe 7. When the elastic element 11 is in its natural state, it applies a thrust to the sealing element 10 toward the mounting interface 6, causing the closed end of the sealing element 10 to tightly fit the edge of the mounting interface 6 to seal it. Simultaneously, the inner wall of the sealing element 10 completely covers the guide port 9 on the outer wall of the connecting pipe 7, blocking the airflow between the inside of the barrel and the guide path 5. At this time, the switch assembly 8 is in the first state, ensuring a sealed environment inside the barrel. When the dispensing equipment connects to the mounting interface 6 and applies an external force toward the mounting part 2, the sealing element 10 overcomes the elastic force of the elastic element 11 and slides along the connecting pipe 7 toward the mounting part 2, compressing the elastic element 11. The closed end of the sealing element 10 separates from the mounting interface 6 to open it, while its inner wall is offset from the guide port 9, exposing the guide port 9 and connecting the inside of the barrel with the guide path 5, achieving air pressure balance regulation. At this time, the switch assembly 8 switches to the second state, providing air pressure conditions for stable subsequent dispensing of the liquor.

[0025] Furthermore, the support 1 is coaxially provided with an annular first partition plate 12 and an annular second partition plate 13. The first partition plate 12 forms a first space 14, and the mounting part 2 is disposed in the first space 14. The second partition plate 13 and the first partition plate 12 form a second space 15. The guide part 3 is a plurality of guide holes 16 opened on the outer wall of the second partition plate 13 and spaced apart. After the mounting cap 4 is connected to the barrel, the second space 15 forms the guide path 5.

[0026] Specifically, the inner diameter of the first partition plate 12 is smaller than the inner diameter of the second partition plate 13, and the height of the first partition plate 12 is greater than the height of the second partition plate 13. Together, they form a closed double-layer annular structure with the bottom of the support 1. The inner wall of the first partition plate 12 encloses a columnar first space 14, the diameter of which matches the outer diameter of the sealing member 10, thus limiting the movement of the sealing member 10. An annular second space 15 is formed between the inner wall of the second partition plate 13 and the outer wall of the first partition plate 12, and the width of the second space 15 is uniform. The guide section 3 specifically consists of a plurality of guide holes 16 evenly spaced along the circumference of the second partition plate 13. The guide holes 16 penetrate the wall thickness of the second partition plate 13, and the axis of the guide holes 16 is consistent with the radial direction of the second partition plate 13, enabling communication between the second space 15 and the external space of the support 1, that is, communication with the inside of the barrel. By placing the guide hole 16 on the second partition plate 13, the flow efficiency of the wine can be improved compared to placing it directly on the outer wall of the support 1.

[0027] Furthermore, the outer side of the second partition plate 13 is provided with a plurality of first support portions 17, which are spaced apart and correspond one-to-one with the positions of the guide holes 16. Specifically, each of the first support portions 17 is a protruding structure integrally formed with the second partition plate 13, and its shape is a cuboid or arc-shaped block, with a height lower than that of the second partition plate 13. The number of the multiple first support portions 17 is exactly the same as the number of guide holes 16, and the position of each first support portion 17 corresponds one-to-one with the position of a guide hole 16. The arrangement of the first support portions 17 can prevent the second partition plate 13 from undergoing radial deformation, thereby affecting the flow of the wine.

[0028] Furthermore, the connecting pipe 7 is provided with a snap-fit ​​section 18 in the middle, the snap-fit ​​section 18 is used to snap-fit ​​with the mounting part 2, one end of the connecting pipe 7 is placed in the first space 14, and the other end extends out of the first space 14.

[0029] Specifically, the connecting pipe 7 has a concave area in the middle, forming a snap-fit ​​section 18. During assembly, one end of the connecting pipe 7 is passed through the mounting part 2, and the two ends of the snap-fit ​​section 18 are snapped into the two ends of the mounting part 2 respectively, thereby achieving axial positioning of the connecting pipe 7 and preventing the connecting pipe 7 from moving with the sealing part 10 when the dispensing equipment squeezes the sealing part 10, thus disrupting the pressure balance inside and outside the wine barrel.

[0030] Furthermore, the mounting portion 2 also includes a plurality of extension portions 19, which are spaced apart circumferentially along the mounting portion 2 and extend to the outside of the first space 14. Each extension portion 19 is provided with a second support portion 20 on its outer side.

[0031] Specifically, the mounting part 2 is mostly located within the first space 14, and its end connected to the support 1 has multiple extensions 19. The extensions 19 extend along the axial direction of the connecting pipe 7 to the bottom of the support 1, and the extensions 19 can deform to facilitate the assembly of the connecting pipe 7. To improve the structural strength of the extensions 19, a second support 20 is provided on the outside of each extension 19, and the second support 20 connects the extension 19 and the bottom of the support 1.

[0032] Furthermore, the sealing member 10 is provided with a limiting groove 21 for engaging the elastic member 11 on the side near the mounting part 2, and a limiting part 22 is formed on the side of the limiting groove 21 near the connecting pipe 7. When the switch assembly 8 is in the second state, the limiting part 22 abuts against the mounting part 2.

[0033] Specifically, the sealing member 10 has two coaxial annular baffles on the side near the mounting part 2, and an annular limiting groove 21 is formed between the two annular baffles. The limiting groove 21 can position the elastic member 11 when it is assembled with the sealing member 10, and at the same time, it can prevent the elastic member 11 from shaking when the sealing member 10 slides. The annular baffle located inside the limiting groove 21 extends towards the side near the mounting part 2 to form a limiting part 22, which is used to limit the sliding distance of the sealing member 10 toward the mounting part 2.

[0034] Furthermore, the sealing element 10 is provided with a sealing gasket 23 at one end near the mounting interface 6.

[0035] Specifically, the sealing gasket 23 is elastic and can be installed on the closed end of the sealing member 10 by adhesive or injection molding. When the switch assembly 8 is in the first state (non-use state), the elastic member 11 pushes the sealing member 10 to move towards the mounting interface 6, and the sealing gasket 23 will fit tightly against the end face of the mounting interface 6 to form a sealing surface, further improving the sealing performance of the mounting interface 6.

[0036] Furthermore, the mounting cap 4 has an annular mounting groove 24 located around the mounting interface 6, and a snap-fit ​​portion 25 is formed on the side wall of the mounting groove 24.

[0037] Specifically, the mounting slot 24 is provided to facilitate the connection between the dispensing device and the mounting cap 4. During assembly, the dispensing device is first inserted into the mounting slot 24, and then the dispensing device is rotated to engage with the locking part 25, thereby improving the stability of the installation.

[0038] Example 2 refer to Figure 6 and Figure 7This embodiment provides a wine barrel, including a wine barrel body 26 and a wine spear as described in Embodiment 1, which is installed at the opening of the wine barrel body 26.

[0039] Specifically, when assembling the wine spear with the barrel body 26, installation is achieved by engaging the internal thread of the mounting cap 4 on the wine spear with the external thread at the opening of the barrel body 26. An air pipe 27 is detachably installed on the connecting pipe 7 of the wine spear, allowing the connecting pipe 7 to extend further into the barrel body 26.

[0040] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
