Description

Technical Field

[0001] This application relates to the field of bottled liquid dispensing technology, and in particular to a dispensing needle and a dispensing machine. Background Technology

[0002] In the daily consumption of wine, once the bottle is opened, oxidation can easily occur, affecting the taste. Therefore, to address this issue, a wine extractor is used to puncture the cork and extract the wine. The extractor has a long, thin needle that passes through the cork to create a connection between the bottle and the contents. This method eliminates the need to remove the entire cork, providing a better seal and slowing down the oxidation process, thus extending the wine's shelf life and preserving its optimal flavor.

[0003] Traditional wine siphons include single-tube and double-tube designs. Single-tube siphons are characterized by their small size and minimal damage to the cork, but require pressurizing the bottle through a single tube before dispensing the wine. This sequential exchange of media leads to long waiting times and a slow, intermittent dispensing process. Double-tube siphons, on the other hand, allow simultaneous air intake and exhaust, resulting in faster dispensing compared to single-tube siphons. However, because they require inserting two needles into the cork simultaneously, they are more damaging to the cork, occupy more space, are difficult to operate, and are prone to damage. During use, one side of the needle may bend, or the cork may be damaged and pushed into the bottle. Furthermore, both traditional single-tube and double-tube siphons only connect the inside and outside of the bottle through the needle tube inserted into the cork. When the needle is removed, air can still enter through the needle hole, causing oxidation of the wine, thus presenting a deficiency in wine preservation.

[0004] Therefore, there is a need for an improved wine-taking needle that can improve the speed of wine taking and reduce the difficulty of operation while ensuring that the wine is protected from air pollution and that the wine flavor is maintained to the maximum extent, so as to ensure the convenience and reliability of wine taking.

[0011] In some embodiments, the gas guiding channel and the liquid guiding channel are provided with parallel mounting holes and are located on both sides of the mounting holes. The bottom of the gas guiding channel is connected to the gas chamber through the gas guiding hole, and the top of the liquid guiding channel is connected to the seepage chamber through the seepage hole.

[0012] In some embodiments, a bottom pressure block is provided at the bottom outlet of both the gas delivery channel and the liquid delivery channel, and both the gas inlet and the liquid outlet are opened on the bottom pressure block; the self-sealing components at the gas delivery port and the liquid outlet have the same structure, both including an elastic element, a sealing body and a sealing ring disposed in the channel, the elastic element is pre-pressed in the channel, and presses the sealing body against the gas delivery port or the liquid outlet, and the sealing ring is disposed between the sealing body and the bottom pressure block.

[0013] In some embodiments, the outer surface of the housing is provided with a foolproof mechanism to distinguish between the gas inlet and the liquid outlet.

[0014] In some embodiments, the tip of the needle body is a blind zone of the outer sheath, and the blind zone of the outer sheath is provided with a third opening that communicates with the inner core; at a predetermined distance away from the third opening, a fourth opening that communicates with the outer sheath is provided on the needle body.

Because the inner core and outer shell are integrated, the overall size is similar to that of commercially available single-tube wine-dispensing needles, making it compact, easy to operate, and less damaging to the bottle stopper. Furthermore, the double-layered design allows for independent flow of wine and gas. While dispensing wine, inert gas can be introduced into the bottle through the needle, helping to maintain stable internal pressure and thus facilitating more convenient and stable dispensing.

Additionally, the outer shell is equipped with a self-sealing component that automatically seals the gas and liquid outlets when not in use, further reducing the risk of external air contamination. Therefore, this application ultimately achieves the function of double-needle wine extraction through single-needle insertion, with minimal damage to the bottle stopper. Its structure is compact and easy to use, providing more reliable protection for the wine, and the wine extraction is fast and stable, effectively improving people's drinking experience.

[0025] Figures 1 to 10 An embodiment of the wine-retrieving needle of this application is illustrated schematically.

[0026] like Figures 1 to 10 As shown, this application discloses a wine-collecting needle, which includes: a needle body 1 and a shell 2.

[0027] The needle body 1 has a double-layer structure, including an inner core 11 and an outer shell 12 that are isolated from each other. The outer shell 12 covers the inner core 11. The inner core 11 has a first opening 111 and the outer shell 12 has a second opening 121.

[0028] The outer shell 2 covers and is fixed to one end of the needle body 1. The outer shell 2 is provided with a gas guiding channel 21 and a liquid guiding channel 22. The gas guiding channel 21 is connected to the inner core 11 through the first opening 111 to form a liquid extraction circuit. The liquid guiding channel 22 is connected to the outer shell 12 through the second opening 121 to form a gas delivery circuit.

[0029] Both the gas channel 21 and the liquid channel 22 extend to the bottom surface of the outer shell 2 to form the gas inlet 23 and the liquid outlet 24 respectively. Both the gas inlet 23 and the liquid outlet 24 are equipped with self-sealing parts 3, which can automatically seal when there is no external pressure, maintaining the airtightness of the wine needle and the environment inside the wine bottle.

[0030] Through the above structural design, this application provides an improved wine-dispensing needle. The needle body 1 has a double-layer structure, consisting of an inner core 11 and an outer shell 12, which can be connected to the gas channel 21 and the liquid channel 22 inside the outer shell 2, respectively, thus forming a mutually cooperating gas delivery system and wine dispensing system. Since the inner core 11 and the outer shell 12 are integrated into one tube, its overall size is close to that of single-tube wine-dispensing needles on the market. It is compact and easy to operate. Only one needle body needs to be inserted to achieve simultaneous gas-liquid exchange, with minimal damage to the bottle stopper and fast and stable wine dispensing. The double-layer structure design of the needle body allows the wine and gas to flow independently. While dispensing wine, an inert gas (such as argon) can also be introduced into the bottle through the inner core 11 of the needle body 1, which helps to maintain stable pressure inside the bottle, thus making the wine dispensing operation more convenient and stable, maintaining a relatively stable dispensing rate, and facilitating accurate measurement of the dispensing volume when used with the flow meter function of the wine dispensing machine. Meanwhile, the self-sealing component 3 on the outer casing 2 of this application can automatically seal the gas inlet 23 and the liquid outlet 24 when not in use, further reducing the risk of external air pollution. Therefore, this application ultimately achieves the function of double-needle dispensing of wine through a single-needle insertion, with minimal damage to the bottle stopper. Its structure is compact and easy to use, providing more reliable protection of the wine, and the dispensing is fast and stable, effectively improving people's drinking experience.

[0031] like Figures 1 to 10 As shown, the dispensing needle is inserted into the cork of the wine bottle during use. Once inserted, it does not need to be removed and is stored with the bottle and cork. The dispensing needle itself has a sealing function, thus maintaining a high degree of airtightness and effectively preserving the flavor and taste of the wine. When dispensing wine, the bottle is inverted, with the wine inside submerging the needle tip (1), providing a foundation for dispensing. The outer shell (2) of the dispensing needle connects to the connector of the dispensing machine, which simultaneously injects argon gas into the bottle and draws out the wine. Because the pressure inside the bottle can be maintained by replenishing the gas, the dispensing process remains smooth, preventing flow difficulties and decreasing flow rate due to pressure drop. Therefore, this application ensures rapid and stable dispensing. Combined with the flow meter of the dispensing machine, it can meet the user's needs for quantitative drinking or precise beverage preparation, thereby improving the user experience.

[0032] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 6 , Figures 10 to 12 As shown, a fixing stud 13 is provided at one end of the needle body 1. The fixing stud 13 is used to engage with the thread inside the outer shell 2 to achieve a fixed assembly of the needle body 1 and the outer shell 2. (Refer to...) Figure 6 , Figures 10 to 12 As shown, the inner core 11 of the needle body 1 passes through the fixing stud 13, and correspondingly, the first opening 111 is formed at the bottom of the fixing stud 13. The outer sleeve 12 of the needle body 1 is embedded into the fixing stud 13 at a preset depth, and correspondingly, the second opening 121 is formed on the part of the outer sleeve 12 that protrudes from the fixing stud 13. Thus, the first opening 111 and the second opening 121 are located at opposite ends of the fixing stud 13, and their spatially staggered positions maintain the independence of the gas delivery system and the wine extraction system, preventing them from interfering with each other.

[0033] In some embodiments of this application, such as Figures 10 to 12 As shown, the needle body 1 in this embodiment is an independent accessory. The inner core 11 and outer sleeve 12 of the needle body 1 are both made of metal (such as stainless steel), and are fitted and welded onto a pre-drilled fixing stud 13. The fixing stud 13 has a pre-drilled stepped hole, the inner and outer diameters of which match the outer diameters of the inner core 11 and outer sleeve 12, respectively. After the inner core 11 and outer sleeve 12 are inserted into the fixing stud 13, they are sealed by welding around the fixing stud 13. The welding positions are respectively located at the bottom of the fixing stud 13 (e.g., the bottom of the needle body 13). Figure 11 (as shown by arrow a) and the top of the fixing stud 13 (as shown by arrow a) Figure 11 (As shown by arrow b). Thus, through welding of the two end faces, the upper and lower end faces of the fixing stud 13 form mutually isolated medium spaces, and respectively connect the inner core 11 and the inner cavity of the outer sleeve 12.

[0034] In some embodiments of this application, such as Figure 6 , Figures 10 to 12As shown, the tip of the needle body 1 is a blind zone of the outer jacket. This blind zone means that the cavity of the outer jacket 12 does not extend into this area, so as not to interfere with the flow of the medium in the inner core 11. A third opening 112 is formed in the blind zone of the outer jacket, which connects to the inner core 11. The inner core 11 communicates with the internal space of the bottle through the third opening 112 to allow inert gas to be introduced into the bottle. At a predetermined distance away from the third opening 112, a fourth opening 122 is formed on the needle body 1, which connects to the outer jacket 12. The outer jacket 12 communicates with the internal space of the bottle through the fourth opening 122 to allow the wine to be drawn out. Since a predetermined distance is maintained between the third opening 112 and the fourth opening 122, and the third opening 112 for introducing gas is located at the top, the introduced gas can rise directly and will not interfere with the flowing wine. This design avoids the gas entering the vessel from mixing into the outflowing wine, thus preventing gas waste and impurities in the wine. As a result, it can effectively improve gas utilization, control costs, and improve the accuracy of wine measurement calculations.

[0035] In the illustrated embodiments of this application, as Figure 6 As shown, the needle tip in the outer casing blind area is provided with a non-porous spike, which maintains high strength to smoothly penetrate the cork. In the illustrated embodiment of this application, the outer casing blind area is structurally continuous with the outer casing 12 using the same metal body, the surface of which is provided with a food-grade protective coating. The protective coating protects the needle body from corrosion and reduces frictional resistance, facilitating smooth insertion of the needle into the cork for wine extraction. (Reference) Figure 12 As shown in the illustrated embodiment of this application, an isolation ring 14 is provided on the outer ring near the top of the inner core 11. The isolation ring 14 is used to cut off the inner cavity of the outer sleeve 12 to form a blind zone in the outer sleeve, thereby providing a structural basis for the inner core 11 and the outer sleeve 12 to be integrated into a single tube. The isolation ring 14 can be made of a sealing material. This arrangement not only ensures that the cavities between the inner core 11 and the outer sleeve 12 are isolated from each other, but also reduces the processing difficulty of the needle body. Only a hole needs to be drilled in the complete metal body where the outer sleeve 12 is located, ensuring that the external structure of the needle body is relatively intact and has high strength, thereby better meeting the needs of needle piercing operation. When using this embodiment of the application, after the outer sleeve 12 pierces the cork, the inner core 11 inside it naturally communicates with the bottle body. Therefore, this application only needs to pierce the bottle stopper once, and the piercing body is only a single needle body, which causes little damage to the bottle stopper and avoids the operational difficulties of inserting a traditional double-tube needle into the bottle stopper. Therefore, this application combines the advantages of traditional single-tube wine piercing needles and double-tube wine piercing needles, with an ingenious structure and convenient use. During wine extraction, by monitoring the pressure or volume of wine extracted from the bottle and continuously adding inert gas as needed, a constant pressure can be maintained inside the bottle. Under this constant pressure, the wine will flow out continuously, rapidly, and steadily, thus increasing the extraction speed and ensuring stable and measurable extraction.

[0036] In some embodiments of this application, such as Figures 3 to 10As shown, the outer casing 2 is provided with a mounting hole 25 and a sealing top cover 26. The mounting hole 25 is open upwards and has threads inside. The needle body 1 is screwed into the mounting hole 25 by a fixing stud 13. The bottom cavity of the mounting hole 25 forms an air-containing cavity (such as...). Figure 6 (As shown by arrow A), the gas cavity is used to connect the gas guide channel 21 and the inner core 11. The top surface of the fixing stud 13, the inner wall of the outer shell 2, and the sealing top cover 26 form a seepage cavity (as shown by arrow A). Figure 6 As indicated by arrow B, the second opening 121 of the outer sleeve 12 is exposed within the seepage cavity, thus allowing the seepage cavity to connect the liquid guiding channel 22 and the outer sleeve 12 to form a wine extraction circuit. In this embodiment, food-grade threadlocker is applied between the internal threads of the fixing stud 13 and the outer sleeve 2. The threadlocker prevents the needle body 1 from loosening and further improves the sealing performance, ensuring that the seepage cavity and the gas chamber within the wine extraction needle are isolated from each other, preventing gas or wine from escaping and interfering through the thread gap. Furthermore, in other embodiments of this application, a sealing ring can be provided between the internal threads of the fixing stud 13 and the outer sleeve 2 to achieve isolation between them.

[0037] In some embodiments of this application, such as Figure 6 As shown, a needle-pressing block 27 is provided inside the seepage cavity, partially filling the cavity. Its height is sufficient to compress and fix the fixing stud 13, thus providing continuous pressure to the stud 13 and preventing it from loosening from the mounting hole 25 and affecting structural stability. A limiting countersinking platform matching the needle-pressing block 27 is also provided inside the outer casing 2. The limiting countersinking platform has a similar shape to the needle-pressing block 27, thereby limiting the needle-pressing block 27 and preventing its rotation from affecting assembly. In this embodiment, as... Figure 10 As shown, the needle pressure block 27 is provided with a liquid passage groove 271, which is used to avoid the second opening 121 of the needle body 1. Therefore, while the needle pressure block 27 compresses and fixes the needle body 1, the second opening 121 of the needle body outer sleeve 12 remains unobstructed, ensuring smooth liquid extraction. In some embodiments of this application, such as... Figure 10 As shown, the top of the fixing stud 13 is provided with a hexagonal nut to facilitate the screwing in and assembly of the needle body 1. The groove width of the liquid passage groove 271 is smaller than the width of the hexagonal nut of the fixing stud 13, so it can stably abut against the fixing stud 13 without detachment or misalignment.

[0038] In some embodiments of this application, such as Figures 3 to 10As shown, a sealing gasket 28 is provided between the top of the needle pressure block 27 and the sealing top cover 26. The sealing gasket 28 is used to maintain the airtightness of the seepage cavity to ensure the airtightness of the wine extraction system of the wine extraction needle and prevent the wine from being contaminated and oxidized by outside air. A step is also provided inside the outer shell 2 for placing the sealing gasket 28. The step is used to stably install the sealing gasket 28 and ensure airtight assembly. The sealing gasket 28 can be made of silicone, which can be squeezed and filled into the step to improve the sealing effect.

[0039] In the embodiments of this application, reference is made to Figure 1 As shown, the surface of the sealing top cover 26 is provided with a set of assembly blind holes (two in the illustrated embodiment of this application). The assembly blind holes are used to insert and mate with assembly instruments to achieve the rotational screw connection of the sealing top cover 26. The sealing top cover 26 is installed by being embedded within the outer shell 2 to improve the firmness after assembly. This design makes the sealing top cover 26 less prone to loosening due to friction from external objects, ensuring reliability during the transportation and retrieval of the wine-retrieving needle.

[0040] In this embodiment of the application, reference is made to Figure 2 and Figure 8 As shown, two blind holes are provided on both sides of the bottom surface of the outer casing 2, corresponding to the gas channel 21 and the liquid channel 22. These blind holes can be used to cooperate with the guide structure of the dispensing machine connector to achieve precise docking. In addition, the bottom pressure block 29 is embedded in the surface of the outer casing 2, so that the gas inlet 23 and the liquid outlet 24 have a certain depth, which facilitates the dispensing machine connector to dock tightly, improves the airtightness of gas delivery and liquid dispensing, ensures accurate dispensing, and protects the flavor of the wine.

[0041] In some embodiments of this application, such as Figures 6 to 9 As shown, the gas guiding channel 21 and liquid guiding channel 22 inside the outer casing 2 are arranged parallel to the mounting hole 25 and are located on both sides of the mounting hole 25. They are positioned opposite each other to avoid interference and facilitate the connection of different ejector pins for gas delivery and liquid extraction. The bottom of the gas guiding channel 21 is connected to the gas chamber through the gas guiding hole 211, forming a complete gas delivery circuit. The top of the liquid guiding channel 22 is connected to the seepage chamber through the seepage hole 221, forming a complete liquid extraction circuit.

[0042] In some embodiments of this application, such as Figures 3 to 6 As shown, both the bottom outlets of the gas delivery channel 21 and the liquid delivery channel 22 are equipped with bottom pressure blocks 29. Correspondingly, the gas inlet 23 and the liquid outlet 24 are both located on the bottom pressure blocks 29. The self-sealing components 3 at the gas inlet 23 and the liquid outlet 24 have the same structure, which respectively ensures the airtightness of the two material exchange ports.

[0043] like Figure 3 and Figure 4As shown, the self-sealing component 3 includes an elastic element 31, a sealing body 32, and a sealing ring 33 disposed within the channel. The elastic element 31 is pre-compressed within the channel, pressing the sealing body 32 against the air inlet 23 or the liquid outlet 24 to automatically close the air inlet 23 and the liquid outlet 24 when not in use. The sealing ring 33 is arranged between the sealing body 32 and the bottom pressure block 29 to enhance the airtightness of the air inlet 23 and the liquid outlet 24. In this embodiment, the elastic element 31 is a cylindrical spring, and positioning posts are provided in both the air guide channel 21 and the liquid guide channel 22 to hold the cylindrical spring and ensure its compression direction is stable. The sealing body 32 is a spherical seal with a consistent shape in all directions, so that it can be arbitrarily matched with the sealing gasket 28 and the bottom pressure block 29 to form a reliable seal.

[0044] In some embodiments of this application, the outer surface of the housing 2 is provided with a foolproof mechanism 210 to distinguish between the gas inlet 23 and the liquid outlet 24, thereby providing a basis for the docking direction of the connector and avoiding human error that could lead to reversed direction during the connection process. In this embodiment, the foolproof mechanism 210 is a boss provided on one side of the housing 2. Correspondingly, a matching structure corresponding to the boss can be provided on one side of the connector to uniquely determine the docking direction, ensuring that no accidents occur when docking and taking out wine, and allowing for safe and quick wine extraction.

[0045] According to another aspect, this application also discloses a wine dispensing machine, which includes a machine base and a wine dispensing needle as described in any of the above embodiments. The machine base is provided with a connector, which houses a liquid-dispensing pin and a gas-dispensing pin. When the connector aligns with the outer shell 2 of the wine dispensing needle, the liquid-dispensing pin is sealed to the gas-dispensing port 23 to draw out the wine, and the gas-dispensing pin is connected to the liquid-dispensing port 24 to replenish the wine bottle with inert gas. By simultaneously dispensing liquid and dispensing gas, the pressure inside the wine bottle can be kept relatively stable, thereby maintaining a relatively fast and stable dispensing rate, making it easier for users to dispense wine in a more convenient and controlled manner.

[0046] In summary, this application provides an improved wine-dispensing needle with a double-layered structure, consisting of an inner core and an outer shell. These two parts communicate with the gas and liquid channels within the outer shell, respectively, forming a mutually isolated yet coordinated gas delivery and wine dispensing system. Because the inner core and outer shell are integrated, the overall size is similar to that of commercially available single-tube wine-dispensing needles (its diameter, including the outer shell, is less than 2.5 mm), making it compact, easy to operate, and less damaging to the bottle stopper. Furthermore, the double-layered design allows for independent flow of wine and gas. While dispensing wine, inert gas can be introduced into the bottle through the needle, helping to maintain stable internal pressure and thus facilitating more convenient and stable dispensing. This process requires no opening the bottle, isolates air during dispensing, and provides a stable and rapid flow rate for easy measurement, thus combining the advantages of low-damage single-needle dispensing and rapid dispensing with double-needle dispensing. Additionally, the outer shell is equipped with a self-sealing component that automatically seals the gas and liquid outlets when not in use, further reducing the risk of external air contamination. Therefore, this application ultimately achieves the function of double-needle wine extraction through single-needle insertion, with minimal damage to the bottle stopper. Its structure is compact and easy to use, providing more reliable protection for the wine, and the wine extraction is fast and stable, effectively improving people's drinking experience.
