Description

Technical Field

[0001] This utility model belongs to the technical field of inflatable equipment, and specifically relates to an island-style wine dispenser. Background Technology

[0002] With the diversification of consumption lifestyles and the continuous expansion of the high-end beverage market (such as wine and whiskey), the dispensing and usage of bottled and sealed beverages are gradually developing towards convenience, a sense of ritual, and preservation. In hotels, high-end clubs, and home settings, users have placed higher demands on the intelligence and convenience of wine dispensing devices, as well as the protection of the quality of the wine.

[0003] In existing technologies, some wine dispensers use simple mechanical stopper or needle-punch structures, which can extract liquid from sealed bottles, but have the following technical shortcomings:

[0004] Unstable connection method: The bottle body and the wine dispensing device are mostly connected by unguided or manual pressing, which may result in inaccurate fit and poor sealing, easily leading to air or wine leakage.

[0005] Unsafe gas circuit control: Some products directly introduce high-pressure gas into the bottle and lack a reliable pressure reduction structure. Once misoperated or the component fails, it may cause the bottle to rupture or cause personal injury.

[0006] Low structural integration: Traditional wine extraction equipment is mostly composed of multiple separate devices, which are not only large in size and complex to operate, but also not conducive to unified packaging and convenient deployment;

[0007] Unable to achieve standardized output: The liquid outlet direction is not fixed and the adaptability is poor, making it difficult to meet the needs of desktop, fixed point, and continuous output.

[0008] Therefore, there is an urgent need for a compact, highly integrated, easy-to-use island-style wine dispenser with a safe gas pressure regulation function, which can be sealed and plugged into a standard bottle, automatically pressurize, and precisely control the direction of liquid dispensing, thereby improving the user experience and ensuring the quality and safety of the wine. Utility Model Content

[0009] In order to solve the above-mentioned problems in the prior art, this application provides a central island-style wine dispenser to solve the above-mentioned technical defects.

[0010] This utility model proposes a central island-style wine dispenser, including a dispenser body, a gas cylinder, and a pressure-reducing assembly. The dispenser body has a cavity for accommodating the gas cylinder, and the pressure-reducing assembly is connected to the gas cylinder. An inflation seat extends from the top side of the dispenser body, and the inflation seat has an inflation valve core for inserting an inflation valve core for receiving the liquid dispensing assembly from the bottle. The air passage inside the inflation valve core is connected to the air outlet passage of the pressure-reducing assembly. By integrating the gas cylinder, pressure-reducing assembly, and inflation seat into the central island-style wine dispenser body, a closed gas-driven system is formed, which can directly supply gas to the bottle containing the liquid dispensing assembly, achieving closed liquid dispensing. It features a compact structure, integrated functions, convenient operation, and strong safety.

[0011] In some specific embodiments, the insertion port of the inflation seat is tilted upwards. This upward tilt of the inflation seat opening facilitates natural insertion of the bottle by the user, enhancing ergonomics and ensuring smooth insertion and removal, reducing the risk of jamming and leakage.

[0012] In some specific embodiments, the inner wall of the inflatable seat opening is provided with multiple limiting protrusions. By providing multiple limiting protrusions on the inner wall of the inflatable seat opening, the insertion depth and position of the bottle can be effectively limited, improving the stability and sealing effect of the insertion and connection, and preventing misinsertion or loosening.

[0013] In some specific embodiments, the inflatable base is provided with a liquid outlet notch, the notch of which faces the area below the inflatable base. This downward-facing notch allows the liquid or beverage to flow steadily into the container below, ensuring a clear liquid outlet direction, smooth flow, preventing spillage, and improving cleanliness and accuracy during use.

[0014] In some specific embodiments, the pressure-reducing assembly includes a pressure-reducing valve assembly and a split-type output end cap. The pressure-reducing valve assembly is fixedly connected to the gas cylinder. The pressure-reducing valve assembly has an internal outlet channel. The inner surface of the split-type output end cap has a pressure-pressing structure. When the split-type output end cap is installed with the pressure-reducing valve assembly, the pressure-pressing structure triggers and activates the pressure-reducing valve assembly, thus opening the outlet channel inside the pressure-reducing valve assembly. Activating the pressure-reducing valve through the end cap's pressure, and closing the outlet channel when the end cap is not installed, significantly improves transportation safety and user operation control, preventing accidental pressure release. The activation process of both components does not require a strong seal, eliminating the need for the user to forcefully tighten the valve for high-pressure sealing.

[0015] In some specific embodiments, the split-type output end cap includes an end cap body, an end cap valve core, and an end cap connector. The end cap body and the end cap connector are sealed together by the end cap valve core. The end cap valve core has an air outlet hole inside that communicates with the outlet of the end cap connector. The pressure-relief structure is a raised structure in the middle of the inner surface of the end cap body. This design facilitates modular manufacturing and maintenance / replacement.

[0016] In some specific embodiments, the pressure reducing valve assembly includes a pressure reducing valve body, a piston seat, a piston, a valve core, and a valve core seat. The pressure reducing valve body has a cavity inside that accommodates the piston and the valve core seat. The piston seat is installed at the opening of the cavity on one side of the piston. A first spring is provided between the piston and the piston seat. The valve core is disposed in an air outlet channel inside the piston and the valve core seat. An air outlet valve structure is provided at the bottom of the air outlet channel. The top pressure structure presses against the piston seat, causing the piston to move. The valve core follows the piston's movement and presses against the air outlet valve structure to open the air outlet channel. A through hole is provided in the middle of the piston seat. One end of the piston passes through the through hole and extends beyond the surface of the piston seat, sealingly engaging with the air outlet through hole of the end cap valve core.

[0017] In some specific embodiments, a filter element is provided at the bottom of the air outlet channel, and the air outlet valve structure includes an air outlet valve core and a second spring, with the second spring disposed between the air outlet valve core and the filter element. By providing a filter element at the bottom of the air outlet channel and having the second spring cooperate with the air outlet valve core, impurities can be effectively filtered, clean gas output can be achieved, and the reliability of valve closure can be ensured, thus extending the service life of the equipment.

[0018] In some specific embodiments, a switching valve structure is provided on one side of the pressure reducing valve assembly. This switching valve structure includes a switching valve seat, a switching valve core, a sealing gasket, and a third spring. The switching valve seat has an interconnected axial opening and a radial through-hole. The valve core seat passes through the radial through-hole and engages with the switching valve seat. The switching valve core and the third spring are disposed within the axial opening, with the third spring positioned between the switching valve core and the valve core seat within the axial opening. A side-mounted auxiliary switching valve, which can be opened by pressure, provides an auxiliary function interface for the gas cylinder, such as pressure detection or filling maintenance, improving system functional expandability and operational flexibility. It also features an automatic reset sealing function, ensuring safety and reliability.

[0019] In some specific embodiments, an overpressure relief valve is also provided on one side of the pressure reducing valve assembly, and the overpressure relief valve is equipped with a rupture disc. The configuration of the overpressure relief valve and rupture disc structure ensures that the system releases pressure in a timely manner under abnormal pressure rise conditions, protecting user safety and equipment structural safety, and constructing a multi-layered safety protection system.

[0020] This utility model provides a central island-style wine dispenser that organically integrates a sealed bottle, a liquid dispensing device, a high-pressure gas cylinder, and a pressure reduction and control system. It adopts an oblique insertion structure design and a modular gas path control device, which not only realizes a convenient and safe bottle dispensing process, but also has good structural maintainability, user-friendly operation, and expandability.

Detailed Implementation

[0027] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present invention may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0028] This utility model proposes a central island-style wine dispenser. Figure 1 A schematic diagram of the structure of an island-style wine dispenser according to an embodiment of the present invention is shown, as follows: Figure 1 As shown, the wine dispenser adopts a central island-style structure, with the main body being the island-style wine dispenser body 100, which is mounted on a stable base. An inflation seat 110 is located on one side of the top of the island-style wine dispenser body 100. The inflation seat 110 is a connecting structure extending outwards from one side, with an interface for inserting a wine bottle at its end. The top of the island-style wine dispenser body 100 is a rotatable cap. Since there are no internal pipes restricting the cap, it can rotate 360°. The inflation seat 110 can rotate with it, allowing the user to perform inflation and liquid dispensing operations from any angle. This top cap is removable and replaceable. Besides the inflation seat 110 of this application, it can also be replaced with other ordinary interfaces, using an external inflation head connected via an air tube for inflation. The interface of the inflation seat 110 includes a limiting protrusion 111 for positioning the bottle opening, a dispensing nozzle notch 112 for allowing the liquid to flow out, and an inflation valve core 113 for cooperating with the bottle's dispensing structure. The island-style wine dispenser body 100 is a vertically arranged shell structure. Its interior can accommodate components such as gas cylinders and pressure reducing components as a gas source module. Its top cover can be replaced with a tabletop liquid dispensing module with an inflation base, as in this application, or a regular interface module, depending on the application scenario. The overall shape is compact and can be used for modular installation.

[0029] Figure 2 A cross-sectional structural schematic diagram of an island-style wine dispenser according to a specific embodiment of the present invention is shown, as follows: Figure 2As shown, the island-style dispensing device body 100 has an internal cavity for accommodating a gas cylinder 600. The gas cylinder 600 has its opening facing upwards and is sealed to the lower part of the pressure reducing valve assembly 300 via threads. The pressure reducing valve assembly 300 is used to reduce and stabilize the high-pressure gas in the gas cylinder and then guide it through the split-type output cap 200 mounted on the top to the filling base 110. The filling valve core 113 is a top-pressure triggered structure. Under normal conditions, the gas passage is closed. Only when a bottle with a liquid dispensing component is inserted and the filling valve core 113 is pressed, its internal gas passage is opened, allowing gas to be introduced into the bottle for pressurized liquid dispensing. After being stabilized by the pressure reducing valve assembly, the high-pressure gas enters the filling base 110 through the output cap 200 and the gas pipe, and can be injected into the bottle through the filling valve core 113 for liquid dispensing. The filling base 110 is also equipped with a throttle valve, which can be used to adjust the injection gas flow rate, thereby controlling the dispensing rate. The pressure reducing valve assembly is equipped with an overpressure relief valve 400 and a side-discharge top-pressure type gas cylinder switch valve 500 on both sides, respectively, to realize overpressure protection and detection / filling functions. Through this structural layout, the gas path control and pressure management from the gas cylinder to the wine bottle are completed, ensuring the safe and reliable operation of the entire system.

[0030] Continue to refer to Figure 3 , Figure 3 A cross-sectional structural schematic diagram of a gas cylinder pressure reducing assembly according to a specific embodiment of the present invention is shown, as follows: Figure 3 As shown, the gas cylinder pressure reducing assembly includes a split-type output end cap 200 and a pressure reducing valve assembly 300. The split-type output end cap 200 is detachably installed on the upper part of the pressure reducing valve assembly 300. The main structure of the output end cap 200 includes an end cap body 201, an end cap connector 202, and an end cap valve core 203. The end cap body 201 is a hollow cylindrical structure with an end cap connector 202 at its lower end. The two are connected and sealed by the end cap valve core 203. The end cap valve core 203 has a through-hole for gas outlet and a top-pressure structure at its bottom, which is used to press against the pressure reducing assembly below in the screw-on state, opening the gas passage. The split-type output end cap 200 and the pressure reducing valve assembly 300 can be engaged by a threaded connection. The process of triggering conduction between the two does not require a strong seal, and the user does not need to forcefully tighten the valve to achieve a high-pressure seal at the port. This structure can prevent accidental opening of the gas output during transportation or when not in use, improving safety.

[0031] In a specific embodiment, the pressure reducing valve assembly 300 is fixed to the opening of the gas cylinder 600 and is used to output high-pressure gas after pressure reduction. It includes a pressure reducing valve body 301, a piston seat 302 mounted on its upper part, a piston 303 axially movable within the piston seat, and a first spring 304 installed between the piston and the piston seat. An anti-disengagement structure (such as a corresponding annular protrusion and stroke groove) is provided at the mating point between the piston seat 303 and the inner surface of the cavity of the pressure reducing valve body 301 to prevent the first spring 304 from popping out when the split-type output end cap 201 is not installed. The first spring provides elastic restoring force for primary pressure regulation. An outlet passage is provided inside the piston 303, in which a valve core 305 is installed. The valve core 305 passes through the bottom of the piston and inserts into the valve core seat 306 below, used to control the gas flow. An outlet valve core 307 and a second spring 308 are provided at the bottom of the valve core seat 306. The second spring 308 keeps the outlet valve core 307 closed when not pressed. When the output end cap 200 is screwed in and the piston seat 302 is pressed down, the piston 303 drives the valve core 305 to push the outlet valve core 307, thus opening the outlet path. A filter 309 is also provided below the outlet path to filter particulate impurities in the gas and to support the second spring 308, ensuring stable operation of the system.

[0032] In a specific embodiment, to achieve auxiliary detection and gas replenishment functions, a side-discharge top-pressure type gas cylinder switch valve 500 is provided on one side of the pressure reducing valve assembly, including a switch valve seat 501, a switch valve core 502, a sealing gasket 503, and a third spring 504. The switch valve seat 501 has an axial opening and a radial through hole. The valve core seat 306 passes through the radial through hole and cooperates with the switch valve seat 501 to provide axial positioning, making the piston 303 more stable during axial movement. The switch valve core 502 is installed in the axial opening and is closed by default under the action of the third spring 504. After an external accessory (such as a pressure gauge) is connected and presses against the valve core 502, the gas path is opened. After use, the accessory is removed, and the valve core resets and closes under the action of the third spring, achieving automatic sealing.

[0033] In a specific embodiment, to prevent danger caused by abnormal pressure rise in the gas cylinder, the pressure reducing valve assembly is also equipped with an overpressure relief valve 400. The overpressure relief valve 400 is equipped with a rupture disc or spring preload mechanism. When the pressure inside the cavity exceeds the safety threshold, this structure automatically releases pressure to ensure the safety of the equipment and the user.

[0034] Figure 4 A schematic diagram of the application of an island-style wine dispenser according to a specific embodiment of the present invention is shown, such as... Figure 4As shown, in actual use, the user inverts the bottle 700 equipped with the dispensing device and inserts it into the inflation seat 110 at the top of the island-style dispensing device body 100. The dispensing device can be the dispensing component of the Chinese patent application with publication number CN114671389A previously filed by the applicant. The dispensing nozzle 701 of the dispensing device matches the dispensing nozzle notch so that it faces the downward-facing cup body 800. During operation, the high-pressure gas in the gas cylinder is depressurized and then injected into the bottle 700 through the inflation valve core 113, thereby pressurizing the bottle. The liquid in the bottle flows out from the dispensing nozzle 701 and is injected into the cup body 800, realizing a rapid dispensing operation. This method of use is simple and safe, avoiding oxidation or quality degradation of the liquid in the bottle caused by repeated opening and closing of the bottle. It is particularly suitable for the delicate dispensing of high-end wines or other sealed beverages. In addition, the user can also customize the direction of the dispensing nozzle by rotating the top cover of the island-style dispensing device body 100, and control the dispensing flow rate through the throttle valve.

In this way, this utility model is also intended to cover such modifications and changes if they fall within the scope of the claims of this utility model and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims.
