Description

Technical Field

[0001] This utility model relates to the technical field of beverage drinking equipment, specifically to a wine spear and a wine barrel having the same. Background Technology

[0002] A beer spear, also known as a cask dispensing valve or beer spear, is a key functional component of a beer cask, typically installed at the neck of the cask at the top. The spear achieves a sealed connection to the neck via threads or other means and has built-in movement and dispensing channels for connecting to external bottling equipment or beverage dispensing systems.

[0003] In the industrial bottling process, the beer spear connects to the bottling line, allowing the beer to be drawn into the keg through the spear, achieving efficient and aseptic automated bottling. During the consumer use phase, the beer spear needs to be used in conjunction with a dedicated keg dispenser (such as a beer tap, air pump system, or refrigeration dispenser) to regulate the pressure inside the keg and ensure a stable output of the beer.

[0004] However, existing wine spear structures generally suffer from a significant technical limitation: their dispensing function is highly dependent on the cooperation of an external dispenser. The wine spear itself does not have independent dispensing capabilities; it must mechanically connect with a dispenser to open the wine passage. This design creates a significant barrier for end users—especially home consumers or non-professional users, who often do not have a dedicated dispenser. When users purchase pre-installed wine barrels with wine spears installed, they cannot dispense wine themselves due to the lack of accompanying equipment, rendering the barrel unusable, severely impacting the user experience, and limiting the promotion and application of such barrels in the retail and ready-to-drink markets.

[0005] Therefore, existing technologies still need further development. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a wine spear and a wine barrel having the same, so as to solve the technical problem that the wine spear in the prior art must rely on a dispenser to dispense wine.

[0017] Beneficial effects: Applying the technical solution of this utility model, the wine sponge provided by this utility model includes: a base frame, a cap, and a sealing cap. The base frame is used for installation at the mouth of a barrel. The base frame has a limiting flange and a supporting part. The limiting flange is arranged around the periphery of the supporting part on the outer wall of the supporting part. The limiting flange is used to be located on the edge of the barrel mouth, so that during assembly, the limiting flange abuts against the end face of the barrel mouth to form a mechanical stop. Part of the supporting part is inserted into the barrel body through the barrel mouth. The supporting part has a first chamber and at least two first flow holes.

The cap has a cap body and an extension. The cap body is used to cover the barrel mouth and press and fix the base frame to the barrel body to achieve a reliable connection. The extension is fixed to the top of the cap body and protrudes from the cap body. The extension has a wine outlet and a second chamber that are interconnected. The wine outlet is located at the top of the extension, and the second chamber is connected to the first chamber. A sealing cap can be placed on the extension and is detachably connected to the extension. The sealing cap is used to seal the wine outlet.

[0018] Therefore, the outer wall of the support section of the base frame is provided with a surrounding limiting flange. During assembly, this limiting flange abuts against the end face of the barrel opening, forming an effective mechanical stop to prevent the base frame from being over-inserted or loosened. This structure not only ensures the axial positioning accuracy of the base frame during installation but also significantly enhances the stability and load-bearing capacity of the overall connection, effectively preventing loosening caused by vibration or internal pressure fluctuations during use.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] Please see Figures 1 to 4 According to an embodiment of the present invention, a wine spear is provided, comprising: a base frame 1, a cap 2, and a sealing cap 3. The base frame 1 is for installation at the mouth of a barrel 100. The base frame 1 has a limiting flange 11 and a support portion. The limiting flange 11 is arranged around the periphery of the support portion on the outer wall of the support portion, and is also arranged on the edge of the barrel mouth. A portion of the support portion is inserted into the barrel 100 through the barrel mouth. The support portion has a first chamber 120 and at least two first flow holes 10. Each first flow hole 10 is spaced apart within the first chamber 120, and the first chamber 120 is open to allow passage of each first flow hole 10. The hole 10 is connected to the interior of the barrel body 100; the cap 2 has a cap body 21 and an extension 22. The cap body 21 is used to cover the barrel opening and fix the base frame 1 to the barrel body 100; the extension 22 is fixed to the top of the cap body 21 and protrudes from the cap body 21. The extension 22 has a wine outlet and a second chamber 221 that are connected to each other. The wine outlet is located at the top of the extension 22, and the second chamber 221 is connected to the first chamber 120; the sealing cap 3 can be placed on the extension 22 and the sealing cap 3 is detachably connected to the extension 22. The sealing cap 3 is used to seal the wine outlet.

[0023] The wine spout provided by this utility model includes: a base frame 1, a cap 2, and a sealing cap 3. The base frame 1 is used for installation at the mouth of a barrel 100. The base frame 1 has a limiting flange 11 and a support portion. The limiting flange 11 is arranged around the periphery of the support portion on the outer wall of the support portion. The limiting flange 11 is also arranged on the edge of the barrel mouth, so that during assembly, the limiting flange 11 abuts against the end face of the barrel mouth of the barrel 100 to form a mechanical stop. The support portion is inserted into the barrel 100 through the barrel mouth. The support portion has a first chamber 120 and at least two first flow holes 10. Each first flow hole 10 is spaced apart in the first chamber 120, and the first chamber 120 communicates with the interior of the barrel 100 through each first flow hole 10, so that wine or gas can flow in or out evenly through multiple first flow holes 10, thereby improving flow efficiency, reducing flow resistance, and reducing the risk of foam generation. The cap 2 has a cap body 21 and an extension 22. The cap body 21 is used to cover the mouth of the barrel and press the base frame 1 firmly onto the barrel body 100 to achieve a reliable connection. The extension 22 is fixed to the top of the cap body 21 and protrudes from the cap body 21. The extension 22 has a wine outlet and a second chamber 221 that are interconnected. The wine outlet is located at the top of the extension 22, and the second chamber 221 is connected to the first chamber 120. The sealing cap 3 can be placed on the extension 22 and is detachably connected to the extension 22. The sealing cap 3 is used to seal the wine outlet.

[0024] Therefore, the outer wall of the support portion of the base frame 1 is provided with a surrounding limiting flange 11. During assembly, the limiting flange 11 abuts against the end face of the barrel opening of the barrel body 100, forming an effective mechanical stop to prevent the base frame 1 from being over-inserted or loosened. This structure not only ensures the axial positioning accuracy of the base frame 1 during installation, but also significantly enhances the stability and load-bearing capacity of the overall connection, effectively avoiding loosening caused by vibration or internal pressure fluctuations during use. At the same time, by covering the barrel opening with the cap body 21, the base frame 1 can be pressed and fixed, achieving a reliable connection between the wine spear and the barrel body 100. Furthermore, an extension 22 is provided at the top of the cap body 21. The top of the extension 22 is provided with a wine outlet, and a second chamber 221 communicating with the wine outlet is provided inside the extension 22. When the cap 2 is assembled in place, the second chamber 221 communicates with the first chamber 120 of the base frame 1, thereby forming a continuous fluid channel from the inside of the barrel to the wine outlet. This design allows users to dispense wine directly from the spout without the need for an external dispenser or air pump system, greatly improving ease of use and applicability. Furthermore, the sealing cap 3, detachably connected to the extension 22, effectively seals the spout when not in use, preventing dust contamination, wine evaporation, or accidental leakage. Its detachable structure makes operation simple and smooth, and it is reusable, significantly improving product durability and user experience. Simultaneously, the base 1, cap 2, and sealing cap 3 adopt a modular structure, allowing each component to be independently manufactured, reducing manufacturing difficulty and cost; the assembly process is simple. Moreover, if any component is damaged, it can be replaced individually, extending the overall service life. This wine spear is simple to assemble and easy to operate, effectively solving the technical problem of existing wine spears that require a dispenser to dispense wine.

[0025] Furthermore, the inner wall of the cap body 21 is provided with a second internal thread, and the outer wall of the port of the barrel 100 is provided with an external thread that matches the second internal thread, so that the cap body 21 can be placed on the barrel opening through the thread engagement of the second internal thread and the second external thread, and the cap 2 and the barrel 100 can be connected.

[0026] Furthermore, such as Figure 2 and Figure 3As shown, the cap 2 also includes: a connecting portion 23, which extends vertically, a part of which is inserted into the cap body 21, and another part of which protrudes from the cap body 21. The connecting portion 23 is fixedly connected to the cap body 21. An extension portion 22 is located at the top of the connecting portion 23 and is connected to the cap body 21 through the connecting portion 23. The connecting portion 23 has a first flow channel 230 extending vertically, which communicates with the second chamber 221. When the cap body 21 is placed on the mouth of the bucket, the lower end of the connecting portion 23 extends into the first chamber 120, and the first flow channel 230 communicates with the first chamber 120. The diameter of the connecting portion 23 is larger than the diameter of the extension portion 22, and the diameter of the connecting portion 23 is smaller than the diameter of the cap body 21. The cap body 21, the connecting portion 23, and the cap body 21 form a first stepped structure.

[0027] With the above-described structure, the connecting part 23 has a first flow channel 230 extending vertically. This channel connects to the second chamber 221 above and the first chamber 120 below, forming a continuous and unobstructed flow path. When the cap is assembled, the lower end of the connecting part 23 extends into the first chamber 120 of the base frame 1, achieving precise alignment of the upper and lower chambers. This ensures efficient flow of liquid or gas, reduces flow resistance, and avoids problems with poor dispensing due to channel misalignment or blockage. Furthermore, the connecting part 23 extends downward and inserts into the first chamber 120, serving a guiding and positioning function. During the installation of the cap 2, this insertion structure guides the cap body 21 to accurate alignment, avoiding eccentricity or misalignment, ensuring precise communication between the first flow channel 230 and the first chamber 120, and improving assembly efficiency and consistency. Simultaneously, a portion of the connecting part 23 is inserted into the cap body 21 and fixedly connected thereto, forming an integrated structure. This design not only improves the overall mechanical strength of the cap but also effectively prevents loosening of the connection due to vibration or external forces during use, ensuring the sealing performance between the first flow channel 230 and the first chamber 120 and preventing leakage. Furthermore, the diameter of the connecting portion 23 is larger than that of the extension portion 22 but smaller than that of the cap body 21, so that the cap body 21, the connecting portion 23, and the extension portion 22 together form a first step structure. This first step structure provides axial restraint during the installation of the sealing cap 3, preventing excessive insertion or tilting of the sealing cap 3, ensuring a tight seal with the outlet, and improving connection stability and ease of operation.

[0028] Optionally, the cap body 21, the connecting part 23, and the extension part 22 are integrally formed.

[0029] Furthermore, such as Figure 2 and Figure 3As shown, at least one second flow hole 222 is provided on the bottom wall of the second chamber 221, and the second flow hole 222 is connected to both the second chamber 221 and the first flow channel 230. With this structural arrangement, the second flow hole 222 serves as a transition channel between the second chamber 221 and the first flow channel 230, ensuring that the liquid flows smoothly from each of the first flow holes 10 → first chamber 120 → first flow channel 230 → second flow hole 222 → second chamber 221 → outlet, reducing pressure loss and improving dispensing response speed and flow stability. Simultaneously, the second flow hole 222, located on the bottom wall of the second chamber 221, guides the fluid to smoothly enter the dispensing chamber from below, preventing splashing and eddies caused by liquid directly impacting the inner wall of the chamber from the side or top, thereby effectively reducing foam formation and enhancing the drinking experience.

[0030] Optionally, there are two second flow holes 222, which are spaced apart.

[0031] Furthermore, such as Figure 2 and Figure 4 As shown, the first chamber 120 has a first flow section 121 and a second flow section 122 connected sequentially in a vertical direction. The first flow section 121 is located above the second flow section 122, and the inner diameter of the first flow section 121 is larger than the inner diameter of the second flow section 122, so that when the lower end of the connecting part 23 extends into the first chamber 120, the top end of the second flow section 122 stops the connecting part 23. A stepped surface is formed between the first flow section 121 and the second flow section 122, which is the top end of the second flow section 122.

[0032] With the above-described structure, when the lower end of the connecting part 23 extends into the first chamber 120, the top end of the second flow section 122 stops the connecting part 23, ensuring that the connecting part 23 is accurately installed in the predetermined position and preventing damage to internal components or displacement of the fluid path due to over-insertion. This precise limiting mechanism improves the reliability and stability of the overall assembly.

[0033] Specifically, such as Figures 1 to 3 As shown, the sealing cap 3 includes a sealing cap body 31 and an annular side 32. The sealing cap body 31 has an installation cavity 310. The annular side 32 is disposed in the installation cavity 310 and extends vertically. The top end of the annular side 32 is fixedly connected to the top wall of the installation cavity 310. The inner wall of the annular side 32 is provided with a first internal thread, and the outer wall of the extension 22 is provided with a first external thread that matches the first internal thread. The sealing cap 3 is connected to the extension 22 through the threaded engagement of the first internal thread and the first external thread.

[0034] The aforementioned structural design, through the threaded engagement of the first internal and first external threads, provides a tight mechanical fit, preventing external dust and impurities from entering the outlet and maintaining the cleanliness and hygiene of the internal liquid. Furthermore, during tightening, a dynamic seal is formed between the sealing cap 3 and the extension 22, avoiding the sealing problems that may exist in traditional snap-fit ​​designs, making it particularly suitable for long-term storage or frequent use. Simultaneously, the design of the annular side 32 increases the overall rigidity of the sealing cap 3, making it less prone to deformation during repeated tightening and loosening, thus extending its service life.

[0035] Furthermore, the height of the sidewall of the sealing cap body 31 is greater than the height of the annular side 32; the inner diameter of the mounting cavity 310 is greater than the diameter of the connecting part 23 and smaller than the diameter of the cap body 21, and the diameter of the annular side 32 is smaller than the diameter of the connecting part 23. Consequently, after the sealing cap 3 is installed in place, the bottom end of its sidewall can extend above the cap body 21 to cover the portion of the connecting part 23 that protrudes from the cap body 21. This also ensures that the sidewall of the sealing cap body 31 will not interfere with the connecting part 23 during the screwing-in process, achieving smooth assembly.

[0036] Furthermore, such as Figure 2 As shown, a first sealing ring 34 is installed on the top wall of the sealing cap body 31, and the first sealing ring 34 is located inside the annular side 32. When the sealing cap 3 is placed on the extension 22 and tightened in place, the first sealing ring 34 is pressed between the mating end faces of the sealing cap body 31 and the extension 22, thereby forming a reliable end face seal between the two, effectively preventing wine leakage or external contaminants from entering the wine outlet. This sealing structure not only improves the sealing performance of the sealing cap 3 in the closed state, but also maintains good pressure-resistant sealing capability when there is air pressure inside the system, ensuring the safety and hygiene of the wine bottle during storage, transportation and use.

[0037] Specifically, such as Figure 2 and Figure 4As shown, the extension 22 has a first installation space, and an annular baffle 223 is provided in the first installation space. The annular baffle 223 extends vertically, and the outer wall of the annular baffle 223 and the inner wall of the first installation space form a second chamber 221. The inner wall of the annular baffle and the bottom wall of the first installation space form a placement cavity 224, and the bottom wall of the placement cavity 224 has a first through hole communicating with the placement cavity 224. The base frame 1 also includes: a first support ring 12 and a second support ring 13 extending vertically. The outer wall of the first support ring 12 is connected to a limiting flange 11, and the limiting flange 11 is located at the top of the first support ring 12. The second support ring 13 is located inside the first support ring 12. The first support ring 12 and the second support ring 13 are coaxially arranged, and the inner wall of the first support ring 12 and the outer wall of the second support ring 13 form a first chamber 120. The second support ring 13 has a vertically extending... The movable cavity 130 extends in a straight direction and communicates with the first through hole; the bottom wall of the movable cavity 130 is provided with a second through hole 131 communicating with the inside of the barrel body 100; the wine spear also includes: a movable part 4 and a sealing part 5, the movable part 4 is movably disposed in the movable cavity 130 along the extension direction of the second support ring 13, and the movable part 4 is slidably sealed with the inner wall of the movable cavity 130; the movable part 4 is used to abut against or move away from the bottom end of the extension 22; the movable part 4 is provided with a third through hole 41 and a moving channel 42 extending in a vertical direction, the third through hole 41 is disposed at the top of the movable part 4 and communicates with the placement cavity 224; the moving channel 42 communicates with the third through hole 41 and the second through hole 131 respectively; the sealing part 5 is movably disposed in the moving channel 42 in a vertical direction, and the sealing part 5 is used to block or avoid the third through hole 41. When the external dispenser is inserted into the placement cavity 224 and an external force is applied to the moving part 4 and the sealing part 5 simultaneously, the moving part 4 moves away from the extension 22, while the sealing part 5 moves away from the third through hole 41. Thus, the first chamber 120 is connected to the wine outlet channel of the external dispenser through the gap between the moving part 4 and the extension 22; at the same time, the air inlet channel of the external dispenser is connected to the moving channel 42 through the third through hole 41.

[0038] With the above-described structure, the design of the moving part 4 and the sealing part 5 allows users to easily open the fluid channel by pressing the external dispenser, enabling rapid dispensing of wine. The system automatically resets and closes after releasing the pressure, simplifying operation and providing a more intuitive and convenient user experience. Simultaneously, a sliding seal design is used between the moving part 4 and the movable chamber 130, maintaining good airtightness during movement and effectively preventing gas leakage. This design not only improves system reliability but also avoids dispensing difficulties due to pressure loss, ensuring a smooth and stable dispensing process. Furthermore, the sealing part 5 normally seals the third through hole 41, opening only under pressure to prevent gas leakage or wine spraying due to accidental collisions during transportation or resting. This normally closed design significantly enhances the system's safety level, ensuring safe use by the user. In addition, by incorporating the moving part 4 and the sealing part 5, the wine spear can not only support independent dispensing (i.e., dispensing directly through the cap without an external dispenser) but also seamlessly connect with an external dispenser to achieve automated dispensing. This dual-pathway design significantly enhances the applicability of the wine spear, meeting the needs of different scenarios and flexibly adapting to both home drinking and commercial applications.

[0039] Furthermore, such as Figure 2 As shown, an annular placement groove is provided on the outer wall of the movable part 4 along the circumferential direction of the movable part 4. A second sealing ring 200 is installed in the annular placement groove. The movable part 4 forms a sliding sealing fit with the inner wall of the movable cavity 130 through the second sealing ring 200, thereby preventing the wine from entering the movable channel 42 through the gap between the movable part 4 and the inner wall of the movable cavity 130.

[0040] Furthermore, such as Figure 2 As shown, the movable member 4 includes a movable member body 43 and a protrusion 44. The protrusion 44 is coaxially mounted on the top of the movable member body 43. A moving channel 42 is provided inside the movable member body 43, and a third through hole 41 is opened at the top of the protrusion 44. The diameter of the movable member body 43 is larger than the diameter of the protrusion 44 to form a second stepped structure. The top of the movable member body 43 is used to abut against the bottom end of the extension 22. When the top of the movable member body 43 abuts against the bottom end of the extension 22, at least a portion of the protrusion 44 is inserted into the placement cavity 224 through the first through hole.

[0041] Furthermore, such as Figure 2 As shown, the wine spear also includes a first seal 300, which is sleeved on the protrusion 44 and mounted on the top of the movable body 43. When the movable body 43 moves upward to abut against the bottom end of the extension 22, the first seal 300 is compressed and deformed, forming a reliable sealing fit between the movable body 43 and the bottom end of the extension 22.

[0042] Furthermore, such as Figure 2 As shown, the top end of the first support ring 12 is flush with the top end of the limiting protrusion 11, the height of the second support ring 13 is greater than the height of the first support ring 12, and there is a gap between the top end of the second support ring 13 and the top wall of the connecting part 23.

[0043] Optionally, the limiting flange 11, the first support ring 12, and the second support ring 13 are integrally formed.

[0044] Furthermore, such as Figure 2 As shown, the wine spear also includes: multiple guide blocks 400, which are spaced apart on the side wall of the moving channel 42 along its circumferential direction, and each guide block 400 protrudes from the side wall of the moving channel 42. A guide channel is formed between adjacent guide blocks 400. When the sealing member 5 avoids the third through hole 41, gas flows through the gap between the sealing member 5 and the third through hole 41, and through each guide channel, to the second through hole 131, and then through the second through hole 131 into the interior of the barrel 100.

[0045] Furthermore, such as Figure 2 As shown, the sealing component 5 includes a sealing plate 51 and a second sealing component 52, with the second sealing component 52 installed at the top of the sealing plate 51. When the sealing component 5 seals the third through hole 41, the second sealing component 52 forms a tight sealing fit with the edge of the opening of the third through hole 41.

[0046] Furthermore, the top of the first support ring 12 is provided with an annular positioning groove, and the third sealing ring 500 forms a tight sealing fit with the cap 2 when the cap 2 is connected to the barrel 100.

[0047] Furthermore, such as Figure 2 As shown, the sealing cap 3 has a fourth through hole 33. When the sealing cap 3 is connected to the extension 22, the fourth through hole 33 communicates with the placement cavity 224. Furthermore, when an external dispenser is required, the external dispenser is mounted on the sealing cap 3, and a portion of the external dispenser passes through the fourth through hole 33 and is inserted into the placement cavity 224.

[0048] Specifically, such as Figure 2 As shown, the wine spear also includes an elastic element 6, one end of which abuts against the bottom wall of the movable cavity 130, and the other end of which passes through the moving channel 42 and abuts against the sealing element 5. With this structural arrangement, the elastic element 6 provides a continuous upward elastic pre-tightening force to the sealing element 5. When the external distributor is released, the elastic element 6 pushes the sealing element 5 upward to reset, resealing the third through hole 41, while simultaneously driving the moving element 4 back to its original position, thus cutting off the gas and liquid passages. This automatic reset mechanism ensures that the wine spear can reliably close after each use, avoiding the risk of leakage due to human negligence.

[0049] Optionally, the elastic element 6 is a spring.

[0050] Specifically, such as Figure 2 As shown, the wine spear also includes: a guide sleeve 7, which is installed on the bottom wall of the movable cavity 130 and extends vertically. The second through hole 131 is located inside the guide sleeve 7. The end of the elastic member 6 away from the sealing member 5 passes through the guide sleeve 7 and abuts against the bottom wall of the movable cavity 130. When the moving member 4 moves toward the bottom wall of the movable cavity 130, the top of the guide sleeve 7 is located within the moving channel 42. With this structural arrangement, the guide sleeve 7 provides a stable mounting base for the elastic member 6 and acts as a radial constraint, preventing the elastic member 6 from bending, twisting, or laterally unstable during compression or rebound, ensuring stable axial output of elastic force, and improving the reliability and consistency of the reset action. Furthermore, during the downward movement of the moving member 4, the top of the guide sleeve 7 is located within the moving channel 42, forming a dynamic guiding structure. This combination effectively guides the moving member 4 and the sealing member 5 to move linearly along the axial direction, preventing them from deviating, jamming, or rotating during reciprocating movement, ensuring smooth operation and accurate response. Furthermore, the guide sleeve 7 not only serves as a guide and support structure for the elastic element 6, but also participates in forming the gas flow path (the second through hole 131 is located inside it), and dynamically participates in the cooperation with the moving channel 42. This integrated design achieves a high degree of integration of the three major functions of guiding, supporting, and guiding, with a compact structure and high space utilization.

[0051] Furthermore, such as Figure 4 As shown, the wine spear also includes at least two limiting blocks 8, each limiting block 8 being spaced apart along the circumferential direction of the movable cavity 130 on the bottom wall of the movable cavity 130, and each limiting block 8 being located between the outer wall of the guide sleeve 7 and the inner wall of the movable cavity 130; each limiting block 8 is used to limit the travel of the moving part 4 toward the bottom wall of the movable cavity 130. With this structural arrangement, by setting the limiting blocks 8, a clear lower limit position is provided for the moving part 4, preventing damage to internal components or seal failure due to excessive compression. This precise travel limiting mechanism ensures that each pressing operation is performed within a safe range, avoiding unnecessary mechanical damage. Furthermore, the even distribution of the limiting blocks 8 along the circumferential direction of the movable cavity 130 ensures that the moving part 4 experiences balanced force when contacting the limiting blocks, reducing the occurrence of off-center loading. This not only improves the stability of the moving part 4 during movement but also ensures the consistency of each opening and closing action, enhancing the user experience.

[0052] Specifically, such as Figures 1 to 4As shown, the base frame 1 also includes: an extension member 14, located at the bottom of the second through hole 131, with an insertion channel communicating with the second through hole 131; the spear also includes: an extension tube 9, inserted into the insertion channel and communicating with the second through hole 131 through the insertion channel. This structural arrangement, with the extension member 14, enhances the connection stability between the extension tube 9 and the base frame 1, preventing the extension tube 9 from loosening or shifting during use. Simultaneously, the extension tube 9 ensures that gas transmission is free of dead zones and stagnation, reducing flow resistance.

[0053] Optionally, once the wine spear is installed on the barrel 100, wine can be extracted in two ways: 1. Independent dispensing method when not using a dispenser Without using an external dispenser, the user can remove the sealing cap 3 from the extension 22 of the cap 2 to open the outlet. Then, by tilting the container, the liquid flows out naturally under gravity. At this point, the liquid flows from the first flow holes 10 into the first chamber 120, then sequentially through the first flow channel 230 and the second flow holes 222 into the second chamber 221, finally exiting from the outlet.

[0054] 2. Pressurized dispensing method when using a dispenser When using a dispenser, the sealing cap 3 is connected to the extension 22 of the cap 2 to seal the wine outlet. The dispenser is then installed on the sealing cap 3, with a portion of the dispenser inserted into the placement cavity 224 through the fourth through hole 33.

[0055] When wine needs to be dispensed, the barrel is inverted so that the opening faces downwards, and an external force is applied downwards through the dispenser. This external force pushes the moving part 4 and the sealing part 5 vertically toward the second through hole 131. At this time, the elastic part 6 is in a compressed state, and a gap appears between the moving part 4 and the extension 22, and the sealing part 5 avoids the third through hole 41, thereby opening the gas passage. At this time: Wine path: The wine flows into the first chamber 120 through each first flow hole 10, and then flows to the wine outlet channel of the distributor through the gap between the moving part 4 and the extension 22, thereby realizing wine dispensing.

[0056] Gas path: External pressurized gas flows through the air inlet channel of the distributor to the third through hole 41, and then flows through the guide channels and guide sleeves 7 in sequence to the second through hole 131, and finally enters the barrel through the extension tube 9 to continuously maintain the stable pressure inside the barrel.

[0057] After the wine extraction is completed, the external force is released, and the elastic element 6, under its own restoring force, pushes the sealing element 5 to reset (i.e., moves the sealing element 5 toward the third through hole 41), so that the sealing element 5 seals the third through hole 41. At the same time, it moves the moving element 4 toward the extension 22, so that the moving element 4 abuts against the extension 22, restoring the sealing state, and the system automatically shuts down to prevent leakage.

[0058] Furthermore, when filling the barrel 100 with wine, the filling equipment can also be installed on the sealing cap 3, and downward pressure can be applied to make the moving part 4 and the sealing part 5 move down synchronously to open the fluid channel. At this time, the wine enters the first chamber 120 from the filling equipment through the gap between the moving part 4 and the extension 22, and then flows into the barrel through each of the first flow holes 10, realizing an efficient and sealed automated filling operation.

[0059] This utility model provides a wine barrel, such as Figure 5 As shown, it includes: a barrel body 100; a wine spear, which is the wine spear of the above embodiment, the wine spear is installed on the mouth of the barrel body 100, and the wine spear is detachably connected to the barrel body 100.
