Description

[0001] This application is a divisional application of patent application No. 202110351084.3, with a filing date of March 31, 2021, and a title of "Beverage tapping device". TECHNICAL FIELD

[0002] The present application belongs to the technical field of beverage drinking equipment, and relates to a beverage tapping device. BACKGROUND

[0003] The beverage tapping device is a device for dispensing beverages (such as beer, coffee, soda, etc.) in a beverage container. It is commonly used in commercial scenarios such as bars, cafes, and home scenarios such as parties. Users can quickly dispense beverages through the beverage tapping device.

[0004] The beverage tapping device has a dispenser and a beverage container. In order to ensure the flavor of the beverage, especially the beverage with gas such as carbon dioxide, an inner bag is arranged in the beverage container, the beverage is stored in the inner bag, and the beverage in the inner bag is squeezed out by inflating the air cavity between the inner bag and the beverage container through the inflation assembly, thereby realizing the function of automatic beverage tapping. A connecting component such as a wine spear is arranged at the opening position of the beverage container, which is used to install the beverage container into the dispenser.

[0005] In the prior art, the beverage container is placed into the dispenser, and then a clamping mechanism clamps the connecting component from both ends of the connecting component to fix the beverage container. This clamping mechanism is complex in structure, and the user needs to perform additional clamping operation after placing the beverage container to make the beverage container firmly installed, so the use is not convenient.

[0006] In addition, the beverage tapping device has a dispensing faucet, and a pressing block is arranged in the dispensing faucet (liquid outlet assembly). The pressing block is moved or rotated by turning the faucet, and the wine outlet is controlled by pressing the moving wine outlet to control the opening of the wine outlet. In the prior art, the beverage tapping device has an inflation assembly controlled by a control module. The inflation assembly continuously inflates the air cavity to maintain the pressure in the air cavity within a certain pressure range, so that the user can smoothly dispense the beverage at any time. However, in this way, during the period when the user does not dispense the beverage, the air cavity is still in a relatively high pressure environment, that is, the beverage barrel is in a high pressure state for a long time, which is dangerous, and may even cause damage to the beverage container due to long-term high pressure. It is conventional to increase the thickness of the beverage barrel to avoid easy damage and deformation, or to add a pressure relief valve to the beverage barrel to improve safety. SUMMARY

[0007] To solve the above problems, a beverage tapping device is provided, which has better refrigeration effect on beverages and is more sanitary and safer. The present application can also solve the problem of poor safety of the existing beverage tapping device.

[0045] The specific embodiments of the present application are described below in conjunction with the accompanying drawings and embodiments.

[0046] <EMBODIMENT>

[0047] The beverage tapping device is mainly used for tapping wine, and can also be used for tapping other beverages (such as soda, etc.). In this embodiment, the beverage tapping device is used for tapping wine as an example for detailed description.

[0048] Figure 1 is a schematic diagram of a front view structure of a beverage tapping device in an embodiment of the present application. Figure 2 is a schematic diagram of a three-dimensional structure of a beverage tapping device in an embodiment of the present application. Figure 3 is a schematic diagram of a three-dimensional structure of a beverage tapping device after removing the top cover in an embodiment of the present application.

[0049] As shown in Figures 1 to 3 , the present embodiment provides a beverage tapping device 100, which comprises a beverage container 1 and a dispenser 2. In this embodiment, the beverage tapping device 100 is a wine tapping device 100, and the beverage container 1 is a wine liquid container 1. The wine liquid container 1 is installed in the dispenser 2, and the wine liquid container 1 stores wine liquid. The wine liquid in the wine liquid container 1 is tapped into a wine glass through the dispenser 2.

[0050] Figure 4 is a schematic diagram of a three-dimensional structure of a beverage container in an embodiment of the present application.

[0051] As shown in Figure 4 , the beverage container 1 is also the wine liquid container 1. The wine liquid container 1 comprises a wine barrel 10, an inner bag, and a wine spear 20 arranged at the barrel opening (i.e. the opening of the beverage container 1) of the wine barrel 10.

[0052] The barrel body of the wine barrel 10 is designed to be light-proof, which can prevent ultraviolet rays from irradiating the wine liquid in the wine barrel. The inner bag is arranged in the wine barrel 10, and the wine liquid is stored in the inner bag. The wine spear 20 is sealingly installed at the barrel opening of the wine barrel 10, and has a liquid outlet passage and an air inlet passage. The liquid outlet passage is in communication with the inner bag, and the space between the inner wall of the wine barrel 10 and the inner bag is a gas filling cavity. The air inlet passage is in communication with the gas filling cavity. In the process of tapping wine, gas is filled into the gas filling cavity through the air inlet passage, and the gas compresses the wine liquid in the inner bag to push the valve core in the wine spear 20 to flow out through the liquid outlet passage.

[0053] In this embodiment, the inner bag is a multi-layer composite environment-friendly flexible bag, which can be a three-layer film structure, and the three layers are PET layer, EVOH layer and PET layer in sequence. It can also be a four-layer film structure, and the four layers are PET layer, EVOH layer, nylon layer and PET layer in sequence.

[0054] In this embodiment, the capacity of the wine barrel 10 is 3L, which is suitable for drinking at home or small parties.

[0055] Figure 5 is a top view of the beverage dispensing device after the top cover and the beverage container are removed in the embodiment of the present application. Figure 6 is a sectional view of the beverage dispensing device in the embodiment of the present application.

[0056] As shown in Figure 5 and Figure 6 , the dispenser 2 has a housing 30, a refrigeration assembly, a gas charging and discharging assembly, a liquid outlet assembly, a liquid outlet pipe 70, and a control module (not shown in the figure). The wine container 1 is installed in the housing 30. The control module is electrically connected with the refrigeration assembly and the gas charging and discharging assembly, and is used to control the refrigeration assembly to perform refrigeration and control the gas charging and discharging assembly to perform gas charging and discharging on the gas charging cavity.

[0057] The housing 30 has a base 31, a lower housing portion 32, a limiting cover 33, and a top cover 34.

[0058] The cross section of the base 31 is oval, and the bottom of the base 31 is provided with a plurality of suction cups which can be adsorbed on a smooth plane such as a table top to fix the entire beverage dispensing device 100.

[0059] The side surface of the base 31 is further provided with a main switch 312 which is used to control the connection and disconnection of all circuits in the dispenser 2, that is, when the main switch 312 is off, all circuits in the dispenser 2 are not powered.

[0060] The liquid outlet assembly is installed on the lower housing portion 32, and the position where the liquid outlet assembly 60 is installed is the front of the housing 30, and the position opposite to the liquid outlet assembly 60 is the rear of the housing 30.

[0061] The base 31 is fixedly installed with a wine barrel fixing bracket 313, and the wine barrel fixing bracket 313 is fixedly installed with an aluminum block fixing seat 314. The central position of the aluminum block fixing seat 314 is used to install the wine container 1 so that the wine container 1 is fixedly installed on the aluminum block fixing seat 314.

[0062] The lower housing portion 32 is approximately ellipsoidal, and the front of the housing 30 is provided with a display portion 321 which is used to display the temperature of the wine in the wine barrel 10, the gas pressure in the gas charging cavity, and the remaining capacity of the wine in the wine barrel 10.

[0063] As shown in Figure 1 , in this embodiment, the part of the display portion 321 which displays the temperature of the wine is located on the left side of the liquid outlet assembly 60, and the temperature of the wine is displayed by displaying numerical values.

[0064] The display part 321, the part displaying the gas pressure in the gas-filled cavity, is three discontinuous and same-column arranged light bars arranged along the vertical direction. When only one of the light bars is on, the light bar is red, indicating that the pressure in the gas-filled cavity is 0.3-0.5 bar, and the gas pressure in the gas-filled cavity is low at this time. When two light bars are on, the two light bars are green, indicating that the pressure in the gas-filled cavity is 0.5-0.7 bar, and the gas pressure in the gas-filled cavity is normal at this time. When all the three light bars are on, the three light bars are blue, indicating that the pressure in the gas-filled cavity is 0.7-1 bar, and the gas pressure in the gas-filled cavity is high at this time.

[0065] The part of the display part 321 displaying the remaining wine liquid capacity is located at the right side of the liquid outlet assembly 60, and the remaining capacity of the wine liquid is displayed by four lightable lattices stacked together. When all the four lattices are blue, it indicates that the wine has been dispensed for 0-18 seconds by the dispenser, and the remaining wine is sufficient. When three lattices are blue, it indicates that the wine has been dispensed for 18-36 seconds by the dispenser, and the remaining wine is relatively sufficient. When two lattices are blue, it indicates that the wine has been dispensed for 36-54 seconds by the dispenser, and about half of the wine remains. When one lattice is yellow, it indicates that the wine has been dispensed for 54-72 seconds by the dispenser, and the remaining wine is less. When all the lattices are not on and only the wine barrel-shaped line outside the four lattices is yellow, it indicates that the wine has been dispensed for 72-90 seconds by the dispenser, and the remaining wine is insufficient.

[0066] The front part of the lower part 32 of the shell is also provided with a power switch 322, which is located below the display part 321. The power switch 322 is a touch switch. When the power switch 322 is turned on, the electrical equipment on the circuit in the dispenser 2 starts to work.

[0067] The rear part of the lower part 32 of the shell is provided with a ventilation cover 323, which is densely covered with a plurality of circular holes for allowing the air in the shell 30 to circulate with the outside air for heat dissipation.

[0068] The top end of the rear part of the lower part 32 of the shell is provided with a lower hinge 324, and the bottom end of the rear part of the top cover 34 is provided with an upper hinge 341. The upper hinge 324 cooperates with the lower hinge 341 to rotatably mount the top cover 34 on the upper end of the lower part 32 of the shell.

[0069] Figure 20 It is a partial enlarged view of the beverage dispensing device in the embodiment of the application at the pressure relief control mechanism.

[0070] As Figure 20As shown, the lower hinge 324 is fixedly installed with a pressure relief control mechanism 325 electrically connected with the control module, in this embodiment, the pressure relief control mechanism 325 is a pressure relief micro switch 325. The pressure relief micro switch has a reed for triggering, which is matched with the upper hinge, when the top cover 34 is covered on the lower part of the shell 32, the upper hinge triggers the reed, and the control module receives the signal that the pressure relief micro switch 325 is triggered, and then controls the inflation and deflation assembly to inflate the inflation cavity; when the top cover 34 is rotated from being covered on the lower part of the shell 32 to the open position, the upper hinge is separated from the reed of the pressure relief micro switch 325, and the control module receives the signal that the pressure relief micro switch 325 is not triggered, and then controls the inflation and deflation assembly to deflate the inflation cavity.

[0071] When the top cover 34 is covered on the lower part of the shell 32, the shape of the lower part of the shell 32 and the top cover 34 is similar to that of an eggshell. The periphery of the top cover 34 and the lower part of the shell 32 is a three-dimensional annular curve.

[0072] The front part of the base 31 is also provided with a drip tray 35 for the wine liquid dropped when the wine is poured. The top of the drip tray 35 is provided with a drip tray cover for allowing the liquid to drip into the drip tray cover, and the drip tray cover is provided with a plurality of strip-shaped holes arranged regularly.

[0073] Figure 7 It is a three-dimensional structure diagram of the limiting cover in the embodiment of the application.

[0074] As shown in the figure, Figure 7 The limiting cover 33 is arranged opposite to the base 31 and is fixedly installed at the top end of the lower part of the shell 32.

[0075] The limiting cover 33 is provided with a wine barrel mounting hole 331 for allowing the wine barrel 10 to pass through, and is provided with a limiting cover U-shaped groove 332 at the rear part of the wine barrel mounting hole 331, so that the user can extend into the lower part of the shell 32 through the limiting cover U-shaped groove 332. The rear part of the limiting cover 33 is provided with a hinge mounting hole 333 for allowing the upper hinge 341 and the lower hinge 324 to pass through.

[0076] The limiting cover 33 is also provided with two lamp strips 334 surrounding the wine barrel mounting hole 331. The limiting cover 33 is provided with a lamp strip touch switch 335 near one of the two lamp strips 334, so that the user can make the two lamp strips 334 light up at the same time by touching the lamp strip touch switch 335.

[0077] The front part of the limiting cover 33 is also provided with a groove for allowing the liquid outlet pipe 70 to pass through and mounting the liquid outlet assembly 60, and the groove is communicated with the wine barrel mounting hole 331.

[0078] When the wine barrel 10 is installed into the dispenser 2, more than two-thirds of the wine barrel 10 is buried in the lower part 32 of the shell, that is, more than two-thirds of the wine barrel 10 is located below the lower end of the limiting cover 33, and the other part is located above the upper end of the limiting cover 33.

[0079] The refrigeration assembly has an inner container 41, a refrigeration aluminum block 42, a condenser pipe 43, a compressor 44, a condenser 45, and a fan 46.

[0080] The inner container 41 is fixedly installed at the bottom of the limiting cover 33 and surrounds the barrel wall of the wine barrel 10.

[0081] Figure 8 is a schematic diagram of the three-dimensional structure of the inner container in the embodiment of the present application.

[0082] As shown in Figure 8 , the top of the inner container 41 is adapted to the shape of the limiting cover 33, and the bottom of the inner container 41 is an annular mounting portion 411. The end face of the annular mounting portion 411 is a horizontal plane, which is used to be fixedly connected with the top surface of the refrigeration aluminum block 43.

[0083] The rear part of the inner container 41 is provided with an inner container U-shaped groove 412, which is in communication with the limiting cover U-shaped groove 332, so that the user's hand can be inserted into the inner container U-shaped groove 412 to take the wine barrel 10. The inner container U-shaped groove 412 is equivalent to the accommodating portion U-shaped groove.

[0084] The refrigeration aluminum block 42 is fixedly installed at the top of the aluminum block fixing seat 314, and the inner wall of the refrigeration aluminum block 42 cooperates with the inner wall of the inner container 41 to form an accommodating portion for accommodating the wine barrel 10. The accommodating portion has a shape matched with the opening of the wine barrel 10.

[0085] Figure 9 is a schematic diagram of the three-dimensional structure of the refrigeration aluminum block in the embodiment of the present application.

[0086] As shown in Figure 9 , the shape of the refrigeration aluminum block 42 is adapted to the shape near the opening of the wine barrel 10, and the shape of the wine barrel 10 at the opening is similar to a hemispherical shape. The inner wall of the refrigeration aluminum block 42 is also similar to a hemispherical shape, so that the refrigeration aluminum block 43 can wrap a part of the wine barrel 10. In the present embodiment, the inner wall of the refrigeration aluminum block 42 wraps about one-half of the wine barrel.

[0087] The inner wall of the refrigeration aluminum block 42 is provided with a wine pipe clamping groove 431 for installing the liquid outlet pipe 70. The outer wall of the refrigeration aluminum block 42 is provided with a spiral condenser pipe groove 432. A part of the condenser pipe 43 is embedded in the condenser pipe groove 432. The condenser pipe 43 has cooling liquid flowing therein.

[0088] The bottom of the refrigeration aluminum block 42 is provided with a temperature sensor mounting portion, which is a through hole penetrating the refrigeration aluminum block 42, and a temperature sensor 81 is arranged in the hole. The temperature sensor 81 is wrapped in a sensor rubber pad and embedded in the temperature sensor mounting portion together with the sensor rubber pad, and the temperature sensor mounting portion abuts against the outer wall of the wine barrel 10.

[0089] In this embodiment, the temperature sensor 81 is a temperature control probe, and the sensor rubber pad is arranged so that the temperature control probe only measures the temperature of the outer wall of the wine barrel 10. Since the barrel wall of the wine barrel 10 is very thin and the inner bag in the wine barrel 10 is also very thin, both have good thermal conductivity, so the temperature measured by the temperature control probe can be approximately considered as the temperature of the wine stored in the inner bag.

[0090] The temperature sensor 81 is electrically connected to a control module, and the control module is electrically connected to a display module. The control module controls the corresponding part of the display module to display the measured temperature value according to the temperature value detected by the temperature sensor 81.

[0091] In addition, the control module is also electrically connected to the condenser 41 and the compressor 42. According to the temperature detected by the temperature sensor 81, when the detected temperature is lower than the set minimum temperature threshold, the control module controls the condenser 41 and the compressor 42 to stop working; on the contrary, when the detected temperature is higher than the set maximum temperature threshold, the control module controls the condenser 41 and the compressor 42 to start working to cool the wine in the wine barrel until the temperature sensor 81 detects that the temperature of the wine in the wine barrel is between the minimum temperature threshold and the maximum temperature threshold.

[0092] In this embodiment, the minimum temperature threshold is set to 3°C, and the maximum temperature threshold is set to 8°C, that is, when the temperature of the wine is detected to be lower than 3°C, the refrigeration assembly stops refrigeration, and when the temperature of the wine is detected to be higher than 8°C, the refrigeration assembly starts refrigeration.

[0093] The compressor 44 is fixedly installed on the base 31 and connected to the condensing pipe 43. The top of the condenser 45 is fixedly installed on the wine barrel fixing frame 313 and located at the rear of the shell 30, close to the ventilation cover 323. The condensing pipe 43 is connected to the condenser. The fan 46 is fixedly installed at the rear of the condenser 45 and faces the ventilation cover 323. Through the cooperation of the compressor 44, the condenser 45 and the fan 46, the refrigeration aluminum block is cooled by the cooling liquid in the condensing pipe 43.

[0094] The outer wall of the barrel 10 near the outlet is in contact with the inner wall of the cooling aluminum block 43, so that heat can be transferred between the cooling aluminum block 43 and the barrel 10 and the wine in the inner bag inside the barrel 10. As the cooling aluminum block is being cooled by the coolant in the condenser 43 under the action of the condenser 41 and the compressor 42, the temperature of the wine stored in the inner bag is also reduced.

[0095] Figure 12 This is a three-dimensional structural diagram of the wine spear holder in an embodiment of the present invention.

[0096] like Figure 12 As shown, the wine spear holder 21 has a threaded connection portion 211 and a connection head 212.

[0097] The threaded connection part 211 is in the shape of a round cap, and its inner wall is provided with threads for engaging with the external threads at the mouth of the barrel 10, so as to connect the wine spear 20 to the barrel 10.

[0098] The connecting head 212 is used to install the beverage container 1 into the dispenser 2, and has three L-shaped locking blocks 2121 evenly distributed in a ring. There is a gap between the three L-shaped locking blocks. Each L-shaped locking block includes an arcuate portion surrounding an end of the spout 21 and an extension 2121b extending from one end of the arcuate portion 2121a in a direction away from that end. The arcuate portion 2121a and the extension 2121b are perpendicular to each other, forming an L-shaped structure.

[0099] Figure 10 This is a three-dimensional structural diagram of the aluminum block fixing seat in an embodiment of the present invention. Figure 11 This is a cross-sectional three-dimensional structural diagram of the aluminum block fixing seat in an embodiment of the present invention.

[0100] like Figure 10 and Figure 11 As shown, the aluminum block holder 314 has a spear holder receiving portion 314a and three snap-fit ​​blocks 314b.

[0101] The wine spear holder receiving portion 314a has a shape that matches the threaded connection portion 211 of the wine spear holder 21, and is used to receive the threaded connection portion 211 of the wine spear holder 21.

[0102] The three locking blocks 314b are evenly distributed in a ring and have gaps between them, the size of which allows the arc-shaped portion 2121 of the L-row locking block 2121 on the wine spear holder 21 to pass through.

[0103] The top surface of the snap-fit ​​block 314b is a horizontal surface, and the bottom surface of the snap-fit ​​block 314b is a snap-fit ​​surface 314c. The snap-fit ​​surface 314c is composed of an arc-shaped surface portion and a horizontal surface portion, and the arc-shaped surface portion is the inclined surface portion.

[0104] During the process of installing the beverage container 1 onto the dispenser 2, the wine spear 20 needs to be placed into the wine spear holder 314a of the aluminum block fixing base 314, and the beverage container 1 is rotated so that the gap between the L-shaped locking block 2121 on the wine spear holder 21 and the locking block 314b is aligned, so that the L-shaped locking block 2121 can be inserted into the corresponding gap. Then, the beverage container 1 is rotated so that the arc-shaped part 2121a moves along the locking surface 314c of the locking block 314b. Under the action of the inclined part of the locking block and the locking block 314c, the beverage container 1 moves downward while rotating until the side of the locking block 314b abuts against the extension 2121b of the L-shaped locking block 2121, thus completing the installation and fixing of the beverage container.

[0105] The bottom of the aluminum block holder 314 has a through hole through which the dispensing core 71 of the dispensing pipe 70 passes, meaning that one end of the dispensing pipe is located in the receiving part of the housing 30. When the wine container 1 rotates, the dispensing core 71 also pushes open the sealing core 25 of the wine spear 20, so that the inner bag is connected to the dispensing pipe.

[0106] Figure 13 This is a partial enlarged view of the beverage dispensing device in an embodiment of the present invention at the spout.

[0107] like Figure 13 As shown, the wine spear 20 is installed at the mouth of the wine barrel 10 to seal the mouth. A liquid outlet pipe 70 is installed at the wine spear 20.

[0108] Figure 14 This is a cross-sectional view of the barrel at the wine spear in an embodiment of the present invention.

[0109] like Figure 14 As shown, the wine spear has a wine spear seat 21, a bushing 22, a flange 23, a pressure cap 24, a sealing top core 25, and a flange spring 26.

[0110] The barrel 10 has an external thread at its opening, and the barrel spit seat 21 has an internal thread; the two are connected by screwing on. A bushing 22 is installed at the opening of the barrel 10, with its outer wall tightly fitting against the inner wall of the opening. Near the opening (away from the bottom of the barrel 10), the bushing 22 has an edge with a diameter larger than the opening diameter; this edge secures the bushing at the opening to prevent it from falling into the barrel 10 during installation. The bushing 22 has a hollow center for mounting a flange 23.

[0111] An inner bag mounting part 231 is provided on the flange 23 at a position away from the barrel opening, and the inner bag is sealed and installed on the inner bag mounting part 231. The flange 23 is fixedly installed inside the bushing 22, and an air intake passage is formed between the inner wall of the bushing 22 and the outer wall of the flange 23. Gas enters between the barrel wall of the barrel 10 and the outer surface of the inner bag through this air intake passage. The flange 23 has a hollow structure.

[0112] A pressure cap 24 is arranged in the flange 23 near the inner bag mounting portion 231. The pressure cap 24 has a through hole for wine to flow through and a spring mounting portion extending away from the inner bag mounting portion 231 around the through hole. The hollow structure of the flange 23 cooperates with the through hole of the pressure cap 24 to form a wine outlet passage.

[0113] A sealing top core 25 is arranged in the flange 23. The side of the sealing top core 25 away from the inner bag mounting portion 231 is provided with a sealing gasket 251. A flange spring 26 is arranged in the flange 23. One end of the flange spring 26 is arranged in the spring mounting portion and the other end is arranged in the sealing top core 25. The flange spring 26 is in a compressed state. Under the action of the flange spring 26, the sealing gasket 251 of the sealing top core 26 abuts against the corresponding inclined surface in the flange 23, thereby blocking the wine outlet passage. When the sealing top core 25 is pried open, the wine outlet passage is opened and the wine in the inner bag can flow out of the wine barrel 10 through the wine outlet passage.

[0114] Figure 15 Fig. 4 is a perspective view of the wine outlet pipe in the embodiment of the present application.

[0115] As shown in Fig. 5, the wine outlet pipe 70 comprises a wine outlet top core 71, a wine outlet nozzle 72 and a hose 73 connecting the wine outlet top core 71 and the wine outlet nozzle 72.

[0116] Fig. 6 is a sectional view of the wine outlet top core. Figure 16 As shown in Fig. 7, the wine outlet top core 71 is provided with an L-shaped wine passage 711. The wine passage 711 comprises two straight passages connected to each other, i.e. passage one 711a and passage two 711b. One end of the passage one 711a is near the wine outlet passage of the wine spear 20 and the port of the passage one 711a is located at the bottom of the wine outlet top core 71 as shown in Fig. 8.

[0117] Figure 16 The passage two 711b is perpendicular to the passage one 711a and is connected to the hose 73. The port of the passage two 711b is located at the side of the wine outlet top core 71 as shown in Fig. 9. Figure 16 Figure 16

[0118] The wine outlet top core 71 is further provided with a gas passage 712. The gas passage 712 comprises a passage three 712a parallel to the passage one 711a and a gas hole 712b connecting the passage three 712a and the outside of the wine outlet top core 71. The gas hole 712b is located at the side of the passage three 712a near the port of the passage one 711a.

[0119] ​​​A sealing ring 713 is arranged on the outer wall of the wine outlet tip 71 between the port of the channel 711a and the air hole 712b, for sealing the passage formed by connecting the liquid channel 711 of the wine outlet tip 71 with the liquid outlet passage of the wine lance 20.

[0120] A sealing ring 714 is arranged on the side of the air hole 712b away from the port of the channel 711a, for cooperating with the sealing ring 713 to seal the passage formed by connecting the gas channel 712 of the wine outlet tip 71 with the gas inlet passage of the wine lance 20. The diameter of the sealing ring 714 is larger than that of the sealing ring 713, and the channels 711a and 712a are arranged at the eccentric positions of the wine outlet tip 71.

[0121] The wine outlet tip 71 is provided with two symmetrically distributed air holes 712b, which are both connected with the channel 712a.

[0122] Figure 16 The axis Y-Y of the wine outlet tip 71 is shown, and the distance between the part where the air hole 712b intersects with the outer side surface of the wine outlet tip 71 and the axis Y-Y is smaller than the distance between the groove for mounting the sealing ring 714 and the axis Y-Y.

[0123] The central position of the aluminum block fixing seat 314 is further provided with a wine outlet tip mounting portion for mounting the wine outlet tip 71 and a hose mounting groove 3141 for mounting a part of the hose 73. The wine outlet tip 71 is fixedly mounted on the wine outlet tip mounting portion.

[0124] The other end of the hose 73 is connected with the wine outlet nozzle 72. A part of the hose 73 is arranged in the hose mounting groove 3141 of the aluminum block fixing seat 314, and a part of the hose 73 is arranged in the wine pipe clamping groove 431 of the refrigeration aluminum block 42. The wine pipe clamping groove 431 is provided with a hose clasp for fixing the hose 73, preventing the hose 73 from deviating in the refrigeration aluminum block 43.

[0125] Figure 17 is the sectional view of the wine outlet nozzle of the wine outlet pipe in the closed position in the embodiment of the present application.

[0126] As shown in Figure 17 The wine outlet nozzle 72 includes a wine outlet nozzle seat portion 721 and a wine outlet nozzle head portion 722.

[0127] The wine outlet nozzle seat portion 721 is fixedly connected with the end of the hose 73 away from the wine outlet tip 71, and is connected with the hose 73. The end of the wine outlet nozzle seat portion 721 away from the hose 73 is a sealing head, and a plurality of radial through holes are arranged on the peripheral wall of the sealing head, and a pair of sealing rings are arranged on the outer walls on both sides of the through holes. The wine outlet nozzle head portion 722 is movably sleeved on the side of the wine outlet nozzle seat portion 721 away from the hose 73, and has a wine outlet opening 722a.

[0128] Figure 17 In the embodiment, the wine outlet head 722 is located away from the wine outlet seat 721, and a pair of sealing rings on the sealing head of the wine outlet seat 721 is matched with the inner wall of the wine outlet head 722 to seal the wine outlet 72 so that the wine cannot flow out of the wine outlet 72.

[0129] Figure 18 Fig. 4 is a sectional view of the wine outlet of the liquid outlet pipe in the open position in the embodiment of the present application.

[0130] As shown in Fig. 4, when the wine outlet seat 721 moves towards the wine outlet head 722, the sealing head of the wine outlet seat 721 moves relative to the wine outlet seat 721 so that the sealing ring on the side of the sealing head away from the hose 73 is no longer in contact with the inner wall of the wine outlet head 722 to seal, and the channel in the wine outlet seat 721 is connected to the channel in the wine outlet head 722 through the through hole in the sealing head so that the passage in the wine outlet 72 is opened, and the wine can flow out of the wine outlet 72. Figure 18 The gas charging and discharging assembly includes a gas source, an electromagnetic valve, a gas pipe 51 and an air inlet core 52.

[0131] The gas source is fixedly installed on the base 31 and electrically connected with the control module, and is used to charge the gas charging cavity between the wine barrel 10 and the inner bag.

[0132] In the embodiment, the gas source is a gas pump motor, which is a low-noise and low-vibration miniature electric air pump embedded in a fixed rubber. Under constant pressure, the gas pump motor can greatly prolong the shelf life of the wine. The base 31 is provided with a support for installing the fixed rubber, and the fixed rubber is fixedly installed on the support by screws, so that there is a gap between the gas pump motor and the bottom plate of the base 31. A gas pump shock-absorbing cotton is arranged in the gap to reduce the vibration of the shell caused by the operation of the gas pump motor.

[0133] The electromagnetic valve is arranged on the base 31 and electrically connected with the control module and the gas source, and is installed on the gas pipe 51 to control the pressure in the gas charging cavity and discharge the gas when the pressure is too high.

[0134] As shown in Fig. 3, the aluminum block fixing seat 314 is fixedly connected with the wine barrel fixing frame 313 by screws. The wine barrel fixing frame 313 is fixedly installed with an air inlet core mounting seat 3131 corresponding to the gas passage 712 of the wine outlet top core 71. The air inlet core mounting seat 3131 has a passage for gas flow in the inside, and the bottom of the air inlet core mounting seat 3131 is connected with the gas pipe 51. The gas pipe 51 is connected with the air inlet core mounting seat 3131 and the gas pump motor.

[0135] Figure 13

[0136] ​​One end of the air inlet core 52 is installed in the gas passage 712 of the wine outlet top core 71, and the other end is installed in the air inlet core mounting seat 3131. The middle part of the air inlet core 52 has a convex edge, the part of the air inlet core 52 located at the upper end of the convex edge is inserted into the gas passage 712, and the outer wall of the part at the upper end is provided with two sealing rings for sealing with the gas passage 712; the part of the air inlet core 52 located at the lower end of the convex edge is inserted into the air inlet core mounting seat 3131, and the outer wall of the part at the lower end is provided with a sealing ring for sealing with the inner wall of the air inlet core mounting seat 3131. That is, the air inlet core 52 connects the gas passage 712 and the air inlet core mounting seat 3131, and the gas output by the gas source enters the air inlet cavity between the barrel wall and the inner bag of the wine barrel 10 through the air pipe 51, the air inlet core mounting seat 3131, the air inlet core 52, the gas passage 712 of the wine outlet top core 71, and the air inlet passage in the wine lance 20 in sequence.

[0137] A pressure sensor is also installed on the air pipe 51 for detecting the pressure in the air pipe 51, which is equivalent to detecting the pressure in the inflation cavity. When the pressure sensor detects that the pressure between the wine barrel 10 and the inner bag is greater than the set maximum threshold value, the control module controls the gas source to stop inflating; when the pressure between the wine barrel 10 and the inner bag is less than the set minimum threshold value, the control module controls the gas source to inflate until the pressure in the inflation cavity is greater than the set minimum threshold value. In this embodiment, the set minimum pressure threshold value is 0.3 bar, and the set maximum pressure threshold value is 0.5 bar, that is, when the barrel pressure is greater than 0.5 bar, the inflation is stopped, and when the barrel pressure is less than 0.3 bar, the inflation is performed.

[0138] As shown in Figure 20 When the top cover 34 is closed on the lower part 32 of the shell, the upper hinge triggers the reed, and the control module receives the signal that the pressure relief micro switch 325 is triggered, and controls the gas source to inflate the inflation cavity; when the top cover 34 is rotated from being closed on the lower part 32 of the shell to the open position, the upper hinge is separated from the reed of the pressure relief micro switch 325, and the control module receives the signal that the pressure relief micro switch 325 is not triggered, and controls the electromagnetic valve to deflate the inflation cavity, so that the air pressure in the inflation cavity is less than 0.3 bar, so that the user does not bring danger when taking down the wine barrel 10 due to excessive barrel pressure.

[0139] Figure 19 is a partial enlarged view of the beverage device in the embodiment of the application near the base.

[0140] As shown in Figure 13 and Figure 19As shown, a drip tube connection 3132 is also provided on the barrel mounting bracket 313 near the air inlet core mounting base 3131. The drip tube connection 3132 is used to collect the liquid that drips during the installation of the liquid container 1. The bottom of the drip tube connection 3132 is connected to the drip tube 3133.

[0141] A drip bend 36 is fixedly installed at the front of the bottom end of the housing 30, and the drip bend 36 passes through the front of the housing 30. One end of the drip bend 36 located inside the housing 30 is connected to the other end of the drip tube 3133; the other end of the drip bend 36 located outside the housing 30 extends to the top of the drip tray 35, so that the wine collected by the drip tube connection 3132 can flow into the drip tray 35 through the drip tube.

[0142] Figure 21 This is a partial enlarged view of the beverage dispensing device in an embodiment of the present invention at the liquid dispensing component.

[0143] like Figure 21 As shown, the liquid dispensing assembly 60 includes a faucet holder 61, a faucet rubber pad 62, a micro switch 63, a micro switch fixing plate 64, a faucet housing 65, a spindle 66, a pressure block 67, and a handle 68.

[0144] The front top of the housing 30 has a faucet mounting part at the center, and the faucet fixing bracket 61 is fixedly mounted on the faucet mounting part for connecting and fixing other parts of the liquid dispensing assembly 60.

[0145] The faucet rubber pad 62 is set in the groove of the limiting cover 33 for the liquid outlet pipe 70 to pass through and for the liquid outlet assembly 60 to be installed, and a part of the hose 73 is embedded in the faucet rubber pad 62.

[0146] A micro switch mounting plate 64 is fixedly mounted on a faucet mounting bracket 61, and a micro switch 63 is fixedly mounted on the micro switch mounting plate 64. The spring of the micro switch 63 faces the front of the housing. The micro switch 63 is electrically connected to the control module and is used to control the air source 51 to inflate the air chamber. Specifically, once the micro switch 63 is activated, the control module controls the air source 51 to inflate the air chamber.

[0147] The faucet housing 65 is fixedly mounted on the faucet mounting bracket 61 and has a first side cover 651, a second side cover, and a faucet top cover 653. The first side cover 651 and the second side cover are symmetrically arranged, and the second side cover is fixedly mounted on the first side cover 651 by screws, forming a mounting base for mounting the pressure block 66, the movable spindle 67, and the handle 68. The faucet top cover 653 is rotatably mounted on the mounting base and partially covers the mounting base from the top of the mounting base and from the end of the mounting base away from the front of the housing 30.

[0148] The upper faucet cover 653 is rotatably connected to the mounting base through a rotating shaft. The rotating shaft is arranged at the bottom center of the mounting base slightly away from the front of the shell 30. The upper faucet cover 653 can rotate in the clockwise direction as shown in the figure about the rotating shaft. Figure 21 The top of the mounting base formed by the first side cover 651 and the second side cover and the end of the mounting base away from the front cover 32 are provided with a shell groove for mounting the hose 73 of the first pipe 70 and the wine outlet nozzle 72.

[0149] During the installation of the liquid outlet pipe 70, the user needs to open the upper faucet cover 653, that is, rotate the upper faucet cover 653 so that the shell groove of the mounting base is exposed to the outside, so as to install the hose 73 and the wine outlet nozzle 72 of the liquid outlet pipe 70 into the shell groove.

[0150] A rubber strip 655 is also arranged at the position of the upper faucet cover 653 close to the front of the shell 30, which is located between the upper faucet cover 653 and the mounting base.

[0151] The top of the first side cover 651 and the second side cover is also provided with a magnet. The outer shell 65 of the faucet also has a magnet on both sides of the rubber strip 655, so that the outer shell 65 of the faucet can be attracted by the magnet.

[0152] When the liquid outlet pipe 70 is installed and the upper faucet cover 653 is rotated to cover the shell groove on the mounting base again, the rubber strip 655 can play a buffering role, and at the same time, when the upper faucet cover 653 is rotated close to the rubber strip, the upper faucet cover will be attracted by the magnet and automatically closed on the mounting base.

[0153] A buckle 657 is also arranged in the shell groove at the front end of the mounting base, that is, the end of the mounting base away from the front of the shell 30. The buckle 657 is clamped on the outer wall of the wine outlet nozzle head 722 of the liquid outlet pipe 70. The front end of the shell groove is provided with a structure for fixing the wine outlet nozzle head 722, which can prevent the wine outlet nozzle head 722 from moving towards the base 31.

[0154] The mandrel 66 is arranged through the second cover plate, one end of which extends to the inside of the mounting base, and the other end extends to the outside of the mounting base and is fixedly connected with the handle 68. A gasket is also arranged between the handle 68 and the second cover plate. Figure 21 Rotating the handle 68 in the counterclockwise direction as shown in the figure can make the mandrel 66 rotate in the counterclockwise direction.

[0155] The end of the mandrel 66 extending into the mounting seat is provided with a protrusion 662 extending along the radial direction of the mandrel 66. The mounting seat is also provided with a top rod 663 extending along the horizontal direction. The top rod 663 is movably mounted in the mounting seat, and has a circular hole compressed along the vertical direction at the end away from the front part of the shell 30, the protrusion 662 is inserted into the circular hole, and the end close to the front part of the shell 30 is provided corresponding to the contact of the micro switch 63. When the mandrel 66 is rotated in the clockwise direction as shown in Figure 21 , the protrusion 662 pushes the top rod 663 to move towards the front cover, and pushes the spring to trigger the micro switch 63.

[0156] One end of the pressing block 67 is rotatably connected in the mounting seat formed by the first side cover 651 and the second side cover, and the rotatable connection part is close to the front part of the shell 30. The other end of the pressing block 67 (i.e. the front end of the pressing block 67) has a pressing block end 671 extending towards the base 31. When the wine outlet nozzle is mounted into the shell groove of the mounting seat of the liquid outlet assembly 60, the end surface of the pressing block end 671 abuts against the end surface of the wine outlet nozzle seat part 721 of the wine outlet nozzle 72 away from the wine outlet nozzle head part 722.

[0157] The end of the mandrel 66 extending into the mounting seat is provided with two mandrel connecting parts 664 extending along the radial direction of the movable mandrel. The protrusion 662 is located between the two mandrel connecting parts 664. The end of the mandrel connecting part 664 away from the mandrel 66 is provided with a through hole extending along the axial direction of the mandrel 66, and the middle part of the length direction of the pressing block 67 is also provided with a hole corresponding to the through hole on the mandrel connecting part 664. A shaft passes through the through hole on the mandrel connecting part 664 and the hole on the pressing block 67 to connect the mandrel 66 and the pressing block 67 together.

[0158] When the pressing block 67 is in the initial position (i.e. not pressed down), the wine outlet nozzle top core 723 blocks the wine outlet nozzle seat part 721, and the wine outlet nozzle 72 is in a closed state, and the wine liquid cannot flow out of the wine outlet nozzle 72.

[0159] When the handle 68 drives the mandrel 66 to rotate in the counterclockwise direction as shown in Figure 21 , the pressing block 67 will also rotate in the counterclockwise direction, thereby pushing the wine outlet nozzle seat part 721 of the wine outlet nozzle 72 to move towards the wine outlet nozzle head part 722, that is, the wine outlet nozzle top core 723 moves in the opposite direction relative to the wine outlet nozzle seat part 721, thereby opening the wine outlet nozzle 72. Under the action of the gas pressure in the inflation cavity, the wine liquid in the inner bag flows along the wine outlet top core 71 of the liquid outlet pipe 70, the hose 73 to the wine outlet nozzle 72, and then flows out of the outlet of the wine outlet nozzle 72.

[0160] The bottom of the part where the pressing block 67 is connected with the shaft connecting part 664 (close to the direction of the base 31) is also provided with a reset spring (not shown in the figure), one end of the reset spring is abutted against the mounting seat of the liquid outlet assembly 60, and the other end is abutted against the bottom of the part where the pressing block 67 is connected with the shaft connecting part 664. When the handle 68 drives the shaft 66 to rotate in the clockwise direction shown in the figure, the reset spring is in a compressed state. Figure 21 When the handle 68 is loosened, the pressing block 67 rotates in the counterclockwise direction shown in the figure under the elastic force of the reset spring, and returns to the initial position.

[0161] When the user finishes drinking, the handle 68 is loosened, and the pressing block 67 rotates in the counterclockwise direction shown in the figure under the elastic force of the reset spring, and returns to the initial position. Figure 21

[0162] Figure 22 The figure shows the process of using the beverage dispensing device in the embodiment of the present application.

[0163] As shown in the figure, the specific process of installing the beverage dispensing device and dispensing the beverage is as follows: Figure 22 Step S1, take out a new liquid outlet pipe 70, install the wine tapping core 71 of the liquid outlet pipe 70 to the wine spear 20 of the wine barrel 10, and then enter step S2;

[0180] In addition, a pressure relief micro switch is arranged on the lower hinge of the lower part of the shell, and the shoe micro switch cooperates with the upper hinge on the top cover to trigger, when the top cover is closed on the lower part of the shell, the reed on the pressure relief micro switch is pressed down, the control module controls the air source to fill the gas into the inflation cavity, when the top cover is opened, the reed on the pressure relief micro switch is not pressed down, the control module controls the electromagnetic valve to deflate the inflation cavity, that is, as long as the user opens the top cover, the high-pressure gas in the beverage container begins to discharge until the pressure in the beverage container is less than 0.3 bar, ensuring the safety of the user during the replacement or removal of the beverage container.

[0181] In addition, the liquid outlet assembly is arranged on the dispenser, and the handle, mandrel, pressing block and wine nozzle of the liquid outlet pipe on the liquid outlet assembly cooperate, when the handle is pressed down, the pressing block presses the wine nozzle seat of the wine nozzle towards the wine nozzle head, and then the wine nozzle top core moves to open the channel in the wine nozzle, so that the wine can flow out smoothly.

[0182] In addition, the faucet upper cover on the liquid outlet assembly is rotatable, and the magnets are arranged on the faucet upper cover, the first side cover and the second side cover, and the rubber strip is arranged on the faucet upper cover, and the buckle for fixing the wine nozzle head is arranged in the faucet shell, during the replacement of the liquid outlet pipe, the liquid outlet pipe can be taken out by rotating the faucet upper cover, after replacing the new liquid outlet pipe, the faucet upper cover is closed, and the faucet upper cover is automatically attracted to the first side cover and the second side cover, and the rubber strip can be buffered during the attraction process. The process of replacing the liquid outlet pipe is simple and convenient, and the user can quickly replace it without special training.

[0183] In addition, the front part of the shell is also provided with a display part for displaying the pressure in the inflation cavity, the remaining capacity in the beverage container and the temperature of the wine in the beverage container, so that the user can quickly judge the state of the beverage in the beverage container according to the displayed pressure, remaining capacity and temperature, and can make the beverage and replace the beverage device according to the remaining capacity.

[0184] The above examples are only used to illustrate the specific embodiments of the present application, and the present application is not limited to the description range of the above examples.

[0185] In the embodiment, the beverage container is clamped in the containing part by the external force through the cooperation of the three L-shaped clamping blocks and the three clamping blocks on the aluminum block fixing seat, and in other embodiments, the number of L-shaped clamping blocks and clamping blocks can be set according to the number.

[0186] In other embodiments, the clamping surface of the clamping block can also not have a slope part but be entirely composed of a flat part, which can also achieve the effect of rotating clamping with the L-shaped clamping block.
