Description

Technical Field

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

[0002] A barrel is a container for holding liquid liquor. Typically, a spout is installed at the mouth of the barrel, which works in conjunction with a dispenser to expel the liquor from the barrel. Traditionally, barrels are made of metal, and the corresponding spouts are also typically metal. While this structure is stable, it is expensive and difficult to clean. Most manufacturers lack specialized cleaning equipment for metal barrels and spouts. Therefore, after the liquor in the barrel is used up, the empty barrel needs to be transported to a manufacturer for cleaning, increasing transportation costs.

[0003] With the development of beverage drinking equipment, plastic wine spears have emerged in the market. Plastic wine spears are not only inexpensive to manufacture, but also reduce operating costs because they are disposable, avoiding the hassle of cleaning. They are also cleaner and more hygienic to use. However, due to the characteristics of plastic materials, ensuring the structural stability of plastic wine spears is a key issue that manufacturers need to address.

[0004] The existing structure of a plastic wine spear, as disclosed in patent literature (application number: 201610792379.3), includes a valve body and a base. A base frame is fixedly connected to the lower end of the valve body, and a wine outlet tube passes through and is fixedly connected to the base frame. A wine bag connector is fitted onto the wine outlet tube, and a flexible bag is fixedly connected to the wine bag connector. The base is slidably fitted onto the upper end of the wine outlet tube, and a return spring is provided between the valve body and the base to allow the base to abut against the inner wall of the valve body. This wine spear has the following drawbacks during use: the wine outlet tube engages with a locking protrusion on the base frame via a locking groove, thus fixing the wine outlet tube to the base frame. In this structure, the engagement depth of the locking groove on the dispensing tube and the locking protrusion on the base frame cannot be too deep to ensure that the dispensing tube can be inserted into the base frame for secure locking. This places high demands on the manufacturing precision and fit accuracy of the dispensing tube and the base frame. Furthermore, due to temperature variations in the liquid inside the dispensing tube and the surrounding environment of the barrel, the plastic dispensing tube is prone to shrinkage and deformation, leading to loosening or even detachment from the base frame. Additionally, the dispensing bag connector in this spear also engages with the locking groove on the base frame via a locking protrusion, securing the dispensing bag connector to the base frame. Similarly, to ensure the dispensing bag connector can be fitted onto the base frame, the engagement depth of the locking groove and protrusion cannot be too deep. During use or handling of the barrel, the movement of the liquid inside the flexible bag can also cause some pulling on the dispensing bag connector, potentially leading to detachment and affecting the normal use of the barrel.

[0005] Currently, the conventional technical approach to address the insufficient stability of existing wine spear structures is as follows:

[0006] 1. Add materials that can mitigate plastic deformation to the manufacturing materials. For example, add toughening agents to the materials used to manufacture the spear. By mixing the toughening agents with the resin, the impact strength and toughness of the spear's plastic parts can be improved, and thermal expansion and contraction can be mitigated.

[0007] 2. Structurally, the components such as the wine outlet pipe and base frame are reinforced with reinforcing ribs to alleviate the deformation of plastic parts.

[0008] 3. In terms of installation methods, threaded connections and bolt connections are used instead of snap-fit ​​structures, which makes the connection between the plastic parts of the spear more stable and avoids the problem of snap-fit ​​parts loosening due to thermal expansion and contraction.

[0009] 4. Use the equipment properly and take heat insulation measures during use. Limit the environment in which the barrel is used, such as avoiding direct sunlight and controlling the temperature of the storage area to avoid excessively high or low temperatures, in order to reduce the deformation of the plastic parts of the barrel. Summary of the Invention

[0010] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a wine spear, which solves the problem of insufficient structural stability in existing plastic wine spears.

[0011] The objective of this invention can be achieved through the following technical solution: a wine spear, comprising a valve body, a wine bag connector, and a wine outlet pipe disposed within the valve body, wherein the wine outlet pipe is connected to the valve body via a snap-fit ​​structure, and the wine bag connector comprises a main body portion snap-fitted to the valve body and an annular connecting piece connected to the main body portion, characterized in that a wine guide pipe is integrally formed on the main body portion, extending into the wine outlet pipe from its lower end, and the wine guide pipe and the snap-fit ​​structure are arranged opposite each other radially to each other along the wine outlet pipe, and the inner peripheral wall of the wine outlet pipe abuts against the wine guide pipe.

[0012] This wine spear is installed at the mouth of a wine barrel. Inside the barrel, there is a wine bag for storing the wine. The ring-shaped connecting piece on the wine bag joint is used to seal the connection with the mouth of the wine bag.

[0013] This wine spear features a wine guide tube directly formed on the wine bag connector. During installation, the wine bag connector not only connects to the valve body but also inserts into the wine outlet pipe through the wine guide tube, abutting against the inner circumferential wall of the wine outlet pipe. This creates a plug-in fit between the wine guide tube and the wine outlet pipe, thereby positioning the wine bag connector and enhancing its installation effectiveness. Especially when the wine inside the wine bag is sloshing, it effectively limits the wine bag connector to prevent tilting or displacement, thus greatly improving the installation stability of the wine bag connector.

[0014] Furthermore, the locking structure on the outer peripheral wall of the wine guide tube and the wine outlet tube in this wine spear is arranged opposite to each other radially in the wine outlet tube, and the wine guide tube and the wine outlet tube are abutting each other. Therefore, the wine guide tube of the wine bag connector also forms an internal support for the wine outlet tube, making it less likely for the wine outlet tube to shrink and deform at the locking part, effectively preventing the wine outlet tube from loosening at the locking part with the valve body, and thus ensuring the stability of the wine outlet tube installation.

[0015] Clearly, the wine guide tube of this wine spear serves a dual purpose: it provides internal support for the wine outlet tube, making its installation more stable. Simultaneously, by interlocking with the outlet tube, the guide tube also enhances the installation of the wine bag connector, making it more stable and ultimately significantly improving the structural stability of the wine spear.

[0016] In the aforementioned wine spear, the main body is cylindrical, and the wine guide tube is located inside the main body and coaxially aligned with it. An annular insertion groove is formed between the wine guide tube and the main body, and the lower end of the wine outlet tube is inserted and positioned within this groove. During the dispensing process, the flow of the wine affects the stability of the dispensing tube. This wine spear, through the design of the insertion groove on the wine bag connector, ensures that after the dispensing tube is installed, it is not only fixed to the valve body by the snap-fit ​​connection, but the lower end of the dispensing tube is also positioned by the insertion groove. This greatly increases the stability of the dispensing tube, ensuring a stable connection between the valve body and the dispensing tube and preventing it from loosening. The cylindrical main body structure has high strength, which facilitates its stable snap-fit ​​connection to the valve body.

[0017] In the aforementioned wine spear, a sealing ring is fitted on the outer peripheral wall of the wine outlet tube, abutting against the inner peripheral wall of the main body. The annular connecting piece is connected to the lower end of the main body, and an annular snap-fit ​​flange is provided on the upper edge of the main body. The valve body has several snap-fit ​​tongues arranged around the main body, and the snap-fit ​​flange engages with each snap-fit ​​tongue, so that each snap-fit ​​tongue supports the snap-fit ​​flange. After the wine outlet tube is inserted into the insertion groove, the sealing ring abuts against the wine outlet tube and the main body respectively, thereby positioning the wine outlet tube. This design not only relies on the sealing ring to achieve a better positioning effect for the wine outlet tube, but also allows for a fitting gap between the wine outlet tube and the insertion groove, thus making the installation of the wine outlet tube and the wine bag connector more convenient and labor-saving. By having several snap-fit ​​tongues arranged around the main body engage with the snap-fit ​​flange, all positions in the circumferential direction of the main body can be supported and positioned by the snap-fit ​​tongues, thereby greatly improving the installation stability of the wine bag connector.

[0018] In the aforementioned wine spear, the locking structure is an annular locking groove formed along the circumference of the wine outlet pipe on its outer peripheral wall. The valve body is provided with several locking claws arranged around the wine outlet pipe, each locking into the annular locking groove. By engaging the annular locking groove with the locking claws surrounding it, the wine outlet pipe can be positioned at various points along its circumference, thus greatly improving the installation stability of the wine outlet pipe. Because this wine spear has a wine guide tube integrally formed on the wine bag connector, extending from the lower end of the wine outlet pipe into the pipe, the guide tube provides internal support to prevent the wine outlet pipe from shrinking and deforming. Therefore, even if the annular locking groove is not deep, it can effectively prevent the locking claws from dislodging from the annular locking groove. The shallower locking groove also facilitates the connection between the wine outlet pipe and the valve body.

[0019] In the aforementioned wine spear, the snap-fit ​​structure is a protrusion located on the outer peripheral wall of the wine outlet pipe, and the valve body has an annular snap-fit ​​groove, into which the protrusion snaps into the groove. This structure is relatively easy to manufacture, has low cost, and can also achieve a snap-fit ​​connection between the wine outlet pipe and the valve body.

[0020] In the aforementioned wine spear, the outer peripheral wall of the wine guide tube has annular protrusions arranged circumferentially. The wine guide tube abuts against the inner peripheral wall of the wine outlet tube through these annular protrusions. There are at least two annular protrusions, and they are spaced apart sequentially along the axial direction of the wine guide tube. Preferably, the cross-section of the annular protrusions is arc-shaped, and there are two annular protrusions. During the insertion of the wine guide tube into the wine outlet tube, the wine guide tube abuts against the inner peripheral wall of the wine outlet tube using the annular protrusions. Since the annular protrusions are relatively small structures, they deform during insertion, ensuring that the annular protrusions firmly abut against the inner peripheral wall of the wine outlet tube after insertion, preventing failure to abut. This reduces the precision requirements for the processing of the wine guide tube and the wine outlet tube, making manufacturing easier, and also ensures that the wine outlet tube receives good internal support from the wine guide tube without shrinkage or deformation. The design of multiple annular protrusions increases the internal support effect of the wine guide tube on the wine outlet tube.

[0021] In the aforementioned wine spear, the valve body includes an outer shell and a mounting sleeve disposed within the outer shell. The mounting sleeve includes a cylindrical body with several connecting parts spaced apart circumferentially at its lower end. A vent hole is formed between each pair of adjacent connecting parts. A support arm is connected to each connecting part, and a claw is connected to each support arm. Each support arm is connected to the body via a connecting part, ensuring good connection stability. Simultaneously, the vent hole between adjacent connecting parts ensures the design requirements of the wine spear's air path, allowing gas from the distributor to enter the wine spear to pass through the vent hole and enter the wine barrel, generating high pressure and forcing the wine out of the barrel. During the process of inserting and fixing the wine pipe onto the valve body, both the claw and the support arm undergo some deformation. Therefore, after insertion and fixing, the support arm tends to recover its shape, thus firmly pressing the claw into the annular locking groove, greatly improving the installation stability of the wine pipe.

[0022] In the aforementioned wine spear, one end of the connecting part is connected to the lower port edge of the body, and this end is the outer end of the connecting part. The other end is the inner end of the connecting part. The support arm is vertically arranged, and its lower end is connected to the inner end of the connecting part. The upper end of the support arm is connected to the claw. Any two adjacent claws are fixedly connected to each other. A latch is connected between the lower ends of any two adjacent support arms. The claw is connected to the upper end of the support arm, raising the height of the claw so that the claw and the annular locking groove are a certain distance from the lower end of the wine outlet tube. This facilitates the lower end of the wine outlet tube to be inserted and positioned in the insertion groove on the wine bag connector, giving the wine outlet tube a double positioning effect, namely, the locking positioning formed by the claw and the insertion positioning formed by the insertion groove. This greatly improves the installation stability of the wine outlet tube, ensuring that the locking structure between the valve body and the wine outlet tube maintains a stable connection and preventing the wine outlet tube from loosening.

[0023] In the aforementioned wine spear, the side wall of the support arm facing the claw has a first reinforcing rib connected to the claw, and the side wall facing away from the claw has a second reinforcing rib connected to the connecting plate. Each connecting part has a third reinforcing rib on its bottom surface, corresponding to the first reinforcing rib. The outer side wall of the mounting sleeve has a fourth reinforcing rib, corresponding to the third reinforcing rib. By providing the first reinforcing rib on the support arm and connecting it to the claw, the claw is strengthened, ensuring that after the wine outlet tube is inserted and fixed to the valve body, and after the claw deforms, the claw can generate a large deformation recovery force to firmly abut against the annular locking groove. Similarly, by providing the first and second reinforcing ribs on both sides of the support arm, the support arm is structurally strengthened, ensuring that after the wine outlet tube is inserted and fixed to the valve body, and after the support arm deforms, the support arm can also generate a large deformation recovery force to firmly abut against the annular locking groove. Furthermore, each first reinforcing rib is connected to a fourth reinforcing rib on the outer side wall of the main body via a third reinforcing rib on the bottom surface of the connecting part. This design forms a continuous rib structure, in which the reinforcing ribs can support and reinforce each other, thereby improving the reinforcement effect on the support arm and further increasing the deformation recovery force after the support arm deforms. This ensures that the claws are stably engaged and positioned in the annular engagement groove. At the same time, the continuous rib structure can also significantly improve the overall structural strength of the mounting sleeve, giving the spear good structural stability.

[0024] In the aforementioned wine spear, the wine guide tube is equipped with a dustproof membrane that seals its upper end. During wine barrel transportation and storage, the dustproof membrane prevents external impurities from entering the wine bag, thereby improving drinking hygiene. When normal use is required, simply puncture the dustproof membrane.

[0025] Compared with existing technologies, this wine spear has the following advantages:

[0026] 1. In this wine spear, the clamping structure on the outer peripheral wall of the wine guide tube and the wine outlet tube is set opposite to each other along the radial direction of the wine outlet tube, and the wine guide tube and the wine outlet tube are abutting each other. Therefore, the wine guide tube of the wine bag joint also forms an internal support for the wine outlet tube, making it less likely for the wine outlet tube to shrink and deform at the clamping part, effectively preventing the wine outlet tube from loosening at the clamping part of the valve body, and thus ensuring the stability of the wine outlet tube installation.

[0027] 2. In this wine spear, after the wine outlet pipe is installed, it is subject to a dual positioning effect, namely the snap-fit ​​positioning formed by the claw and the insertion positioning formed by the insertion groove. This greatly improves the installation stability of the wine outlet pipe, ensuring that the snap-fit ​​structure between the valve body and the wine outlet pipe maintains a stable connection and preventing the wine outlet pipe from loosening.

[0039] 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.

[0040] Example 1

[0041] like Figure 1As shown, this wine spear is installed at the mouth of a wine barrel 8 for use. A wine bag 7 for storing wine is placed inside the barrel 8. This wine spear includes a valve body 1, a wine bag connector 2, and a wine outlet pipe 3 located within the valve body 1. The upper end of the wine outlet pipe 3 is fitted with an air-sealing assembly 9 for sealing the air passage of the wine spear. When the wine spear is in use, the air passage is opened by pressing down the air-sealing assembly 9 using a distributor, allowing the gas flowing through the distributor to enter the wine spear.

[0042] The wine outlet pipe 3 is connected to the valve body 1 via a snap-fit ​​structure. The wine bag connector 2 includes a main body 21 that snaps onto the valve body 1 and has an annular connecting piece 22. The annular connecting piece 22 on the wine bag connector 2 is used to seal the opening of the wine bag 7. A wine guide pipe 23 is integrally formed on the main body 21, extending into the wine outlet pipe 3 from its lower end. The wine guide pipe 23 and the snap-fit ​​structure are arranged opposite each other radially to the wine outlet pipe 3, and the inner circumferential wall of the wine outlet pipe 3 abuts against the wine guide pipe 23. This design allows the wine guide pipe 23 of the wine bag connector 2 to also provide internal support for the wine outlet pipe 3, making it less likely for the wine outlet pipe 3 to shrink and deform at the snap-fit ​​point. This effectively prevents the wine outlet pipe 3 from loosening at the snap-fit ​​point with the valve body 1, thereby ensuring the stability of the wine outlet pipe 3 installation.

[0043] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, the main body 21 of the wine bag connector 2 is cylindrical, and the wine guide tube 23 is located inside the main body 21 and is coaxially arranged with the main body 21. The outer peripheral wall of the wine guide tube 23 has two circumferentially arranged annular protrusions 231. The two annular protrusions 231 are arranged alternately along the axial direction of the wine guide tube 23. The wine guide tube 23 abuts against the inner peripheral wall of the wine outlet tube 3 through these annular protrusions 231. The cross-section of the annular protrusions 231 is arc-shaped. Of course, in actual manufacturing, the number of annular protrusions 231 can also be three, four, etc., and the cross-section of the annular protrusions 231 can also be triangular, rectangular, trapezoidal, etc. This wine spear has a wine guide tube 23 directly formed on the wine bag connector 2. During installation, the wine bag connector 2 is not only connected to the valve body 1, but also inserted into the wine outlet tube 3 through the wine guide tube 23, and abuts against the inner circumferential wall of the wine outlet tube 3. This makes the wine guide tube 23 and the wine outlet tube 3 form a plug-in fit, thereby positioning the wine bag connector 2 and increasing the installation effect of the wine bag connector 2. Especially when the wine in the wine bag 7 is shaking, it can effectively limit the wine bag connector 2 to avoid tilting or displacement, thereby greatly improving the installation stability of the wine bag connector 2.

[0044] like Figure 3 , Figure 5 and Figure 6As shown, an annular insertion groove 24 is formed between the wine guide tube 23 and the main body 21, and the lower end of the wine outlet tube 3 is inserted and positioned in the insertion groove 24. A sealing ring 4 is also fitted on the outer peripheral wall of the wine outlet tube 3, which abuts against the inner peripheral wall of the main body 21. An annular connecting piece 22 is connected to the lower end of the main body 21. An annular snap-fit ​​flange 211 is provided on the upper port edge of the main body 21. The valve body 1 has several latches 1b2 arranged around the main body 21. The snap-fit ​​flange 211 snaps into each latch 1b2 so that each latch 1b2 simultaneously supports the snap-fit ​​flange 211. After the wine outlet tube 3 is inserted into the insertion groove 24, the sealing ring 4 can abut against the wine outlet tube 3 and the main body 21 respectively, thereby positioning the wine outlet tube 3. This design not only allows the sealing ring 4 to achieve a better positioning effect for the wine outlet tube 3, but also allows for a fitting gap between the wine outlet tube 3 and the insertion groove 24. Therefore, the installation between the wine outlet tube 3 and the wine bag connector 2 is more convenient and labor-saving.

[0045] like Figure 5 and Figure 6 As shown, the valve body 1 includes an outer shell 1a and a mounting sleeve 1b disposed within the outer shell 1a. The snap-fit ​​structure is an annular snap-fit ​​groove 31 formed on the outer peripheral wall of the wine outlet pipe 3 along its circumference. The valve body 1 is provided with several claws 1b3 arranged around the wine outlet pipe 3, and each claw 1b3 is snapped into the annular snap-fit ​​groove 31. By having several claws 1b3 surrounding the annular snap-fit ​​groove 31 snap into the annular snap-fit ​​groove 31, the wine outlet pipe 3 can be positioned at various positions in its circumference by the claws 1b3, thereby greatly improving the installation stability of the wine outlet pipe 3.

[0046] like Figure 7 and Figure 8 As shown, the mounting sleeve 1b includes a cylindrical body 1b1. The lower end of the body 1b1 is connected to several connecting portions 1b5 spaced apart circumferentially along the body 1b1. A vent hole 5 is formed between each pair of adjacent connecting portions 1b5. A support arm 1b6 is connected to each connecting portion 1b5, and a claw 1b3 is connected to each support arm 1b6. The vent hole 5 between adjacent connecting portions 1b5 ensures the design requirements of the wine spear's air path, allowing the gas from the distributor entering the wine spear to pass through the vent hole 5 and enter the wine barrel 8, generating high pressure inside the wine barrel 8 and forcing the wine out of the barrel 8. One end of the connecting part 1b5 is connected to the lower port edge of the body 1b1 and this end is the outer end of the connecting part 1b5. The other end is the inner end of the connecting part 1b5. The support arm 1b6 is vertically arranged and its lower end is connected to the inner end of the connecting part 1b5. The upper end of the support arm 1b6 is connected to the claw 1b3. Any two adjacent claws 1b3 are fixedly connected to each other. A latch 1b2 is connected between the lower ends of any two adjacent support arms 1b6.

[0047] like Figure 6 , Figure 7 and Figure 8 As shown, the support arm 1b6 has a first reinforcing rib 1b7 on the side wall facing the claw 1b3, which is connected to the claw 1b3. The side wall facing away from the claw 1b3 has a second reinforcing rib 1b8 connected to the connecting plate. The bottom surface of each connecting part 1b5 has a third reinforcing rib 1b9 that is connected to the first reinforcing rib 1b7 in a one-to-one correspondence. The outer side wall of the body 1b1 of the mounting sleeve 1b has a fourth reinforcing rib 1b10 that is connected to the third reinforcing rib 1b9 in a one-to-one correspondence.

[0048] Example 2

[0049] This embodiment is basically the same as embodiment one in structure and principle, except that: Figure 9 As shown, the wine guide tube 23 is equipped with a dustproof membrane 6 that seals its upper end. During the transportation and storage of the wine barrel 8, the dustproof membrane 6 is designed to prevent external impurities from entering the wine bag 7, thereby improving drinking hygiene. When normal use is required, simply puncture the dustproof membrane 6.

[0050] Example 3

[0051] This embodiment is basically the same as embodiment one in structure and principle, except that: Figure 10 As shown, the snap-fit ​​structure consists of a protrusion 32 on the outer peripheral wall of the dispensing pipe 3, and an annular snap-fit ​​groove 1b4 on the valve body 1. The protrusion 32 snaps into the snap-fit ​​groove 1b4. This structure is relatively easy to manufacture and has a low cost, while also achieving a snap-fit ​​connection between the dispensing pipe 3 and the valve body 1.
