[0040] The specific implementation of the present invention is described below with reference to the accompanying drawings and embodiments.

[0041] <Example>

[0042] The beverage dispenser is mainly used for dispensing wine, and can also be used for dispensing other beverages (such as soda, etc.). In the present embodiment, the beverage dispenser is used for dispensing wine as an example for detailed description.

[0043] Figure 1 It is a schematic diagram of the main structure of the beverage making device in an embodiment of the present invention. Figure 2 It is a schematic diagram of the three-dimensional structure of the beverage making device in an embodiment of the present invention. Figure 3 2 is a schematic diagram of the three-dimensional structure of the beverage dispensing device with the top cover removed according to the embodiment of the present invention.

[0044] like Figures 1 to 3As shown, this embodiment provides a beverage dispensing device 100, comprising a beverage container 1 and a dispenser 2. In this embodiment, the beverage dispensing device 100 is a wine dispensing device 100, and the beverage container 1 is a wine container 1. The wine container 1 is mounted in the dispenser 2, which stores wine. The dispenser 2 is used to dispense the wine from the wine container 1 into a wine glass.

[0045] Figure 4 2 is a schematic diagram of the three-dimensional structure of a beverage container in an embodiment of the present invention.

[0046] like Figure 4 As shown, the beverage container 1 is also a wine container 1 , which includes a wine barrel 10 , an inner bag, and a wine spear 20 arranged at the barrel mouth of the wine barrel 10 (that is, the opening of the beverage container 1 ).

[0047] The barrel body of the wine barrel 10 adopts a light-proof design to prevent ultraviolet rays from irradiating the wine inside the barrel. An inner bag is set in the wine barrel 10, and the wine is stored in the inner bag. The wine spear 20 is sealed at the barrel mouth of the wine barrel 10 and has a liquid outlet passage and an air inlet passage. The liquid outlet passage is connected to the inner bag. The space between the inner wall of the wine barrel 10 and the inner bag forms an air chamber, and the air inlet passage is connected to the air chamber. During the wine-making process, gas is injected into the air chamber through the air inlet passage. The gas compresses the wine in the inner bag, pushing open the valve core in the wine spear 20 and flowing out through the liquid outlet passage.

[0048] In this embodiment, the inner bag is a multi-layer composite environmentally friendly flexible bag, which can be a three-layer film structure, in which the three layers of film are PET layer, EVOH layer and PET layer in sequence, or a four-layer film structure, in which the four layers of film are PET layer, EVOH layer, nylon layer and PET layer in sequence.

[0049] In this embodiment, the capacity of the wine barrel 10 is 3L, which is suitable for drinking at home or in small gatherings.

[0050] Figure 5 It is a top view of the embodiment of the present invention with the top cover and beverage container removed. Figure 6 It is a cross-sectional view of a beverage making device according to an embodiment of the present invention.

[0051] like Figure 5 and Figure 6 As shown, the dispenser 2 comprises 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). The wine container 1 is mounted within the housing 30. The control module is electrically connected to the refrigeration assembly and the gas charging and discharging assembly to control the refrigeration assembly to cool the wine and the gas charging and discharging assembly to inflate and deflate the gas chamber.

[0052] The housing 30 includes a base 31 , a housing lower portion 32 , a limiting cover 33 and a top cover 34 .

[0053] The cross section of the base 31 is oval, and a plurality of suction cups are provided on the bottom of the base 31 , which can be adsorbed on a smooth surface such as a desktop to fix the entire beverage dispenser 100 .

[0054] A main switch 312 is also provided on the side of the base 31. The main switch 312 is used to control the connection and disconnection of all circuits in the distributor 2. That is, when the main switch 312 is turned off, all circuits in the distributor 2 are not powered.

[0055] The liquid outlet assembly is installed on the lower portion 32 of the housing, with the position where the liquid outlet assembly 60 is installed being the front portion of the housing 30 , and the corresponding position opposite to the liquid outlet assembly 60 being the rear portion of the housing 30 .

[0056] A wine barrel fixing frame 313 is fixedly mounted on the base 31, and an aluminum block fixing seat 314 is fixedly mounted on the wine barrel fixing frame 313. 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 mounted on the aluminum block fixing seat 314.

[0057] The lower portion 32 of the shell is approximately ellipsoidal in shape, and a display portion 321 is provided at the front of the shell 30 for displaying the temperature of the wine in the barrel 10, the gas pressure in the inflation chamber, and the capacity of the remaining wine in the barrel 10.

[0058] like Figure 1 As shown, in this embodiment, the portion of the display unit 321 that displays the temperature of the wine is located on the left side of the liquid outlet component 60 and displays the temperature of the wine by displaying a numerical value.

[0059] In the display unit 321, the part that displays the gas pressure in the inflation chamber is three discontinuous light bars arranged in the same column along the vertical direction. When only one light bar is lit, the light bar is red, indicating that the pressure in the inflation chamber is 0.3bar~0.5bar, and the air pressure in the inflation chamber is low at this time; when two light bars are lit, the two light bars are green, indicating that the pressure in the inflation chamber is 0.5bar~0.7bar, and the air pressure in the inflation chamber is normal at this time; when all three light bars are lit, the three light bars are blue, indicating that the pressure in the inflation chamber is 0.7bar~1bar, and the air pressure in the inflation chamber is high at this time.

[0060] The portion of the display unit 321 that displays the remaining wine volume is located to the right of the liquid outlet assembly 60. Four illuminated, superimposed grids indicate the remaining wine volume. If all four grids are illuminated blue, it indicates that the dispenser has dispensed wine for 0 to 18 seconds and sufficient wine is remaining. If three grids are illuminated blue, it indicates that the dispenser has dispensed wine for 18 to 36 seconds and sufficient wine is remaining. If two grids are illuminated blue, it indicates that the dispenser has dispensed wine for 36 to 54 seconds and approximately half of the wine is remaining. If one grid is illuminated yellow, it indicates that the dispenser has dispensed wine for 54 to 72 seconds and less wine is remaining. If all grids are unilluminated and only the barrel-shaped line outside the four grids is illuminated yellow, it indicates that the dispenser has dispensed wine for 72 to 90 seconds and insufficient wine is remaining.

[0061] The front portion of the housing lower portion 32 is further provided with a power switch 322, which is located below the display portion 321. The power switch 322 is a touch switch, and when the power switch 322 is turned on, the electrical equipment on the circuit in the dispenser 2 starts to work.

[0062] A ventilation cover 323 is provided at the rear of the lower portion 32 of the housing. The ventilation cover 323 is densely covered with a plurality of circular holes for allowing the air in the housing 30 to circulate with the external air for heat dissipation.

[0063] A lower hinge 324 is installed at the top end of the rear portion of the lower shell part 32, and an upper hinge 341 is installed at the bottom end of the rear portion of the top cover 34. The upper hinge 324 cooperates with the lower hinge 341 so that the top cover 34 is rotatably installed on the upper end of the lower shell part 32.

[0064] Figure 20 It is a partial enlarged view of the pressure relief control mechanism of the cross-sectional view of the beverage dispenser in the embodiment of the present invention.

[0065] like Figure 20 As shown, a pressure relief control mechanism 325 electrically connected to the control module is fixedly mounted on the lower hinge 324. 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 cooperates with the upper hinge. When the top cover 34 is closed on the lower part 32 of the housing, the upper hinge triggers the reed. After receiving the signal that the pressure relief micro switch 325 is triggered, the control module controls the inflation and deflation assembly to inflate the inflation chamber. When the top cover 34 rotates from the closed position on the lower part 32 of the housing to the open position, the upper hinge disengages the reed of the pressure relief micro switch 325. After receiving the signal that the pressure relief micro switch 325 is not triggered, the control module controls the inflation and deflation assembly to deflate the inflation chamber.

[0066] When the top cover 34 is covered on the housing lower portion 32, the housing lower portion 32 and the top cover 34 are shaped like an eggshell. The periphery where the top cover 34 and the housing lower portion 32 fit together is a three-dimensional annular curve.

[0067] A drip tray 35 is also provided at the front of the base 31 for collecting the liquor dripping when the liquor is poured. The top of the drip tray 35 is provided with a drip tray cover for allowing liquid to drip into, and the drip tray cover is provided with a plurality of strip holes arranged in a regular pattern.

[0068] Figure 7 3D is a schematic diagram of the three-dimensional structure of the limiting cover in an embodiment of the present invention.

[0069] like Figure 7 As shown, the limiting cover 33 is arranged opposite to the base 31 and is fixedly mounted on the top of the lower portion 32 of the shell.

[0070] A wine barrel mounting hole 331 is provided in the center of the limiting cover 33 near the front of the housing 30 for passing the wine barrel 10 therethrough. A U-shaped slot 332 is provided at the rear of the wine barrel mounting hole 331, allowing a user to reach into the housing lower portion 32 through the U-shaped slot 332. A hinge mounting hole 333 is provided at the rear of the limiting cover 33 for passing the upper hinge 341 and the lower hinge 324 therethrough.

[0071] The limiting cover 33 is further provided with two light strips 334, which surround the wine barrel mounting hole 331. A light strip touch switch 335 is provided near one of the light strips 334 on the limiting cover 33, and the user can light up the two light strips 334 at the same time by touching the light strip touch switch 335.

[0072] The front portion of the limiting cover 33 is further provided with a groove for allowing the liquid outlet pipe 70 to pass through and for installing the liquid outlet assembly 60 , and the groove is communicated with the wine barrel installation hole 331 .

[0073] When the wine barrel 10 is installed in the dispenser 2, more than two-thirds of it is buried in the lower part 32 of the shell, that is, more than two-thirds of the wine barrel 10 is located at the lower end of the limit cover 33, and the other part is located at the upper end of the limit cover 33.

[0074] The refrigeration assembly includes an inner tank 41 , a refrigeration aluminum block 42 , a condenser tube 43 , a compressor 44 , a condenser 45 and a fan 46 .

[0075] The inner liner 41 is fixedly mounted on the bottom of the limiting cover 33 and surrounds the barrel wall of the wine barrel 10 .

[0076] Figure 8 It is a schematic diagram of the three-dimensional structure of the inner container in an embodiment of the present invention.

[0077] like Figure 8 As shown, 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 surface of the annular mounting portion 411 is a horizontal surface, which is used to be fixedly connected to the top surface of the refrigeration aluminum block 43.

[0078] The rear portion of the liner 41 is provided with an liner U-shaped groove 412, which is connected to the limit cover U-shaped groove 332, allowing the user to reach into the liner U-shaped groove 412 to take the wine barrel 10. The liner U-shaped groove 412 is equivalent to the accommodating portion U-shaped groove.

[0079] The cooling aluminum block 42 is fixedly mounted on the top of the aluminum block fixing seat 314, and the inner wall of the cooling aluminum block 42 cooperates with the inner wall of the inner liner 41 to form a receiving portion for receiving the wine barrel 10. The receiving portion has a shape that matches the opening of the wine barrel 10.

[0080] Figure 9 It is a schematic diagram of the three-dimensional structure of the refrigeration aluminum block in an embodiment of the present invention.

[0081] like Figure 9 As shown, the shape of the cooling aluminum block 42 matches the shape near the opening of the wine barrel 10. The wine barrel 10 is shaped like a hemisphere at the opening, and the inner wall of the cooling aluminum block 42 is also similar to a hemisphere, so that the cooling aluminum block 43 can wrap around a portion of the wine barrel 10. In this embodiment, the inner wall of the cooling aluminum block 42 wraps around approximately half of the wine barrel.

[0082] The inner wall of the cooling aluminum block 42 is provided with a wine pipe slot 431 for mounting the liquid outlet pipe 70. The outer wall of the cooling aluminum block 42 is provided with a spiral condenser pipe groove 432. A portion of the condenser pipe 43 is embedded in the condenser pipe groove 432. The condenser pipe 43 has a flowing coolant.

[0083] A temperature sensor mounting portion is provided at the bottom of the cooling aluminum block 42. The temperature sensor mounting portion is a through hole that passes through the cooling aluminum block 42. A temperature sensor 81 is provided 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 then rests against the outer wall of the wine barrel 10.

[0084] In this embodiment, the temperature sensor 81 is a temperature control probe. The setting of the sensor rubber pad enables the temperature control probe to only measure 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 inside the wine barrel 10 is also thin, the thermal conductivity of both is very good. Therefore, the temperature measured by the temperature control probe can be approximately regarded as the temperature of the wine stored in the inner bag.

[0085] The temperature sensor 81 is electrically connected to the control module, which is in turn electrically connected to the 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.

[0086] 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 condenser 41 and the compressor 42 are controlled to stop working; conversely, when the detected temperature is higher than the set maximum temperature threshold, the condenser 41 and the compressor 42 are controlled to start working to cool down 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.

[0087] In this embodiment, the minimum temperature threshold is set to 3°C and the maximum temperature threshold is set to 8°C. That is to say, when the temperature of the wine is detected to be lower than 3°C, the refrigeration component stops refrigeration, and when the temperature of the wine is detected to be higher than 8°C, the refrigeration component starts refrigeration.

[0088] Compressor 44 is fixedly mounted on base 31 and connected to condenser 43. The top of condenser 45 is fixedly mounted on barrel mounting bracket 313, located at the rear of housing 30, near ventilation cover 323. Condenser 43 is connected to condenser 43. Fan 46 is fixedly mounted at the rear of condenser 45, facing ventilation cover 323. Compressor 44, condenser 45, and fan 46 work together to cool the aluminum block using the coolant in condenser 43.

[0089] Part of the outer wall of the wine barrel 10 near the outlet is in contact with the inner wall of the refrigeration aluminum block 43, so that heat can be transferred between the refrigeration aluminum block 43 and the wine barrel 10 as well as the wine in the inner bag inside the wine barrel 10. Since the refrigeration 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.

[0090] Figure 12 2 is a schematic diagram of the three-dimensional structure of the wine spear seat in an embodiment of the present invention.

[0091] like Figure 12 As shown, the wine lance seat 21 has a threaded connection portion 211 and a connection head 212 .

[0092] The threaded connection portion 211 is in the shape of a round cap, and a thread is provided on the inner wall thereof for matching with the external thread at the barrel mouth of the wine barrel 10 , so as to connect the wine spear 20 to the wine barrel 10 .

[0093] The connecting head 212 is used to mount the beverage container 1 in the dispenser 2. It has three L-shaped blocks 2121 evenly distributed in a circular pattern. There are gaps between the three L-shaped blocks. Each L-shaped block includes an arcuate portion surrounding the end of the lance holder 21 and an extension portion 2121b extending from one end of the arcuate portion 2121a away from the end. The arcuate portion 2121a and the extension portion 2121b are perpendicular to each other, forming an L-shaped structure.

[0094] Figure 10 It is a schematic diagram of the three-dimensional structure of the aluminum block fixing seat in an embodiment of the present invention. Figure 11 It is a schematic diagram of the cross-sectional three-dimensional structure of the aluminum block fixing seat in an embodiment of the present invention.

[0095] like Figure 10 and Figure 11 As shown, the aluminum block fixing seat 314 has a wine lance seat accommodating portion 314a and three clamping blocks 314b.

[0096] The lance seat accommodating portion 314 a has a shape matching the threaded connection portion 211 of the lance seat 21 and is used to accommodate the threaded connection portion 211 of the lance seat 21 .

[0097] The three engaging blocks 314 b are evenly distributed in a ring shape and have gaps between them. The gaps are large enough to allow the arc-shaped portions 2121 of the L-row engaging blocks 2121 on the wine spear seat 21 to pass through.

[0098] The top surface of the clamping block 314b is a horizontal surface, and the bottom of the clamping block 314b is a clamping surface 314c. The clamping surface 314c is composed of an arcuate surface portion and a horizontal surface portion. The arcuate surface portion is the inclined surface portion.

[0099] When installing the beverage container 1 on the dispenser 2, the wine spear 20 needs to be placed in the wine spear seat accommodating portion 314a of the aluminum block fixing seat 314, and the wine container 1 needs to be rotated so that the gap between the L-shaped clamping block 2121 on the wine spear seat 21 and the clamping block 314b is aligned, allowing the L-shaped clamping block 2121 to be inserted into the corresponding gap. Then, the beverage container 1 is rotated so that the arc-shaped portion 2121a moves along the clamping surface 314c of the clamping block 314b. Under the action of the inclined portion of the clamping block 314c, the wine container 1 moves downward while rotating until the side surface of the clamping block 314b abuts against the extending portion 2121b of the L-shaped clamping block 2121, thus completing the installation and fixation of the wine container.

[0100] The bottom of the aluminum block fixing base 314 has a through hole for the wine outlet core 71 of the liquid outlet tube 70 to pass through. In other words, one end of the liquid outlet tube is located in the receiving portion of the housing 30. When the wine container 1 rotates, the wine outlet core 71 pushes open the sealing core 25 of the wine spear 20, allowing the inner bag to communicate with the liquid outlet tube.

[0101] Figure 13 It is a partial enlarged view of the sectional view of the beverage dispenser at the wine spear in the embodiment of the present invention.

[0102] like Figure 13 As shown, the wine spear 20 is installed at the barrel mouth of the wine barrel 10 to seal the barrel mouth. A liquid outlet pipe 70 is installed at the wine spear 20.

[0103] Figure 14 1 is a cross-sectional view of a wine barrel at the wine spear in an embodiment of the present invention.

[0104] like Figure 14 As shown, the wine spear comprises 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 .

[0105] The mouth of the wine barrel 10 is externally threaded, and the lance seat 21 is internally threaded, connecting the two through a screw threaded engagement. A bushing 22 is installed at the mouth of the wine barrel 10, with the outer wall of the bushing 22 tightly fitting the inner wall of the mouth. A rim with a larger diameter than the mouth of the barrel is located near the mouth of the wine barrel 10 (away from the bottom of the wine barrel 10). This rim is located near the mouth of the wine barrel 10 to prevent the bushing 22 from falling into the wine barrel 10 during installation. The center of the bushing 22 is hollow, which is used to mount the flange 23.

[0106] Flange 23 is provided with an inner bag mounting portion 231 at a position away from the barrel opening. The inner bag is sealably mounted on this portion. Flange 23 is fixedly mounted within liner 22. An air intake passage is formed between the inner wall of liner 22 and the outer wall of flange 23. Gas enters through this intake passage between the barrel wall of wine barrel 10 and the outer surface of the inner bag. Flange 23 is a hollow structure.

[0107] A pressure cap 24 is located within the flange 23 near the inner bag mounting portion 231. The pressure cap 24 has a through hole for allowing the wine to flow through, and a spring mounting portion surrounding the through hole and extending away from the inner bag mounting portion 231. The hollow structure of the flange 23 cooperates with the through hole in the pressure cap 24 to form a liquid outlet passage.

[0108] A sealing top core 25 is mounted within the flange 23. A sealing gasket 251 is installed on the side of the sealing top core 25 facing away from the inner bag mounting portion 231. A flange spring 26 is mounted on the spring mounting portion at one end and on the sealing top core 25 at the other end. The flange spring 26 is compressed. Under the action of the flange spring 26, the sealing gasket 251 of the sealing top core 26 rests against the corresponding inclined surface within the flange 23, blocking the liquid outlet passage. When the sealing top core 25 is pushed open, the liquid outlet passage is opened, allowing the wine in the inner bag to flow out of the wine barrel 10 through the liquid outlet passage.

[0109] Figure 15 2 is a schematic diagram of the three-dimensional structure of the liquid outlet pipe in an embodiment of the present invention.

[0110] like Figure 15 As shown, the liquid outlet pipe 70 includes 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. The wine outlet top core 71 is installed on the wine spear 20 and pushes open the sealing top core 25 to open the liquid outlet passage.

[0111] Figure 16It is a cross-sectional view of the wine outlet top core.

[0112] like Figure 16 As shown, an L-shaped wine channel 711 is provided in the wine outlet core 71. The wine channel 711 comprises two connected straight channels, namely channel 1 711a and channel 2 711b. One end of channel 1 711a is close to the liquid outlet passage of the wine spear 20. The end of channel 1 711a is located at Figure 16 The bottom of the wine outlet core 71 is shown. Channel 2 711b is perpendicular to channel 1 711a and is connected to the hose 73. The port of channel 2 711b is located as shown in FIG. Figure 16 The side of the wine outlet top core 71 is shown.

[0113] A gas channel 712 is further provided in the wine outlet top core 71, which includes a channel 3 712a parallel to the channel 1 711a and an air hole 712b connecting the channel 712a with the outside of the wine outlet top core 71. The air hole 712b is located on one side of the channel 3 712a near the end of the channel 1 711a.

[0114] A sealing ring 713 is provided on the outer wall of the wine outlet top core 71 between the end of the channel 1 711a and the air hole 712b, which is used to seal the passage formed by connecting the liquid channel 711 of the wine outlet top core 71 and the liquid outlet passage on the wine spear 20.

[0115] A second sealing ring 714 is provided on the side of air hole 712b, away from the end of channel 1 711a. This seal cooperates with seal 1 713 to seal the passageway formed by the connection between gas channel 712 of wine outlet core 71 and the air inlet passageway on wine spear 20. The diameter of seal 1 714 is larger than that of seal 1 713. Channel 1 711a and channel 3 712a are respectively located at eccentric positions on wine outlet core 71.

[0116] Two symmetrically distributed air holes 712b are provided on the wine outlet top core 71, and both of the air holes 712b are connected to the channel three 712a.

[0117] Figure 16 The axis YY of the wine outlet top core 71 is shown, and the distance between the part where the air hole 712b intersects with the outer side surface of the wine outlet top core 71 and the axis YY is smaller than the distance between the groove for installing the sealing ring 2 714 and the axis YY.

[0118] A wine outlet top core mounting portion for mounting the wine outlet top core 71 and a hose mounting groove 3141 for mounting a portion of the hose are also provided at the central position of the aluminum block fixing seat 314. The wine outlet top core 71 is fixedly mounted on the wine outlet top core mounting portion.

[0119] The other end of the hose 73 is connected to the wine spout 72. A portion of the hose 73 is disposed within the hose mounting slot 3141 of the aluminum block fixing seat 314, and a portion is disposed within the wine pipe clamping slot 431 of the cooling aluminum block 42. A hose clip is provided in the wine pipe clamping slot 431 to secure the hose 73 and prevent it from shifting within the cooling aluminum block 43.

[0120] Figure 17 2 is a cross-sectional view of the wine outlet nozzle of the liquid outlet pipe in the embodiment of the present invention when it is in a closed position.

[0121] like Figure 17 As shown, the wine spout 72 includes a wine spout seat 721 and a wine spout head 722 .

[0122] The spout seat 721 is fixedly connected to the end of the hose 73 away from the wine outlet core 71 and is in communication with the hose 73. The end of the spout seat 721 away from the hose 73 is a sealing head. The sealing head has a plurality of radially extending through-holes formed on its circumferential wall, and a pair of sealing rings are provided on the outer walls of each of these through-holes. The spout head 722 is movably mounted on the side of the spout seat 721 away from the hose 73 and has a wine outlet 722a.

[0123] Figure 17 In the embodiment, the wine spout head 722 is located away from the wine spout seat 721 , and a pair of sealing rings on the sealing head of the wine spout seat 721 cooperate with the inner wall of the wine spout head 722 to seal, so that the wine cannot flow out of the wine spout 72 .

[0124] Figure 18 2 is a cross-sectional view of the wine outlet nozzle of the liquid outlet pipe in the embodiment of the present invention when it is in the open position.

[0125] like Figure 18 As shown, when the wine spout seat 721 moves toward the direction approaching the wine spout head 722, the sealing head of the wine spout seat 721 moves relative to the wine spout seat 721, so that the sealing ring on the side of the sealing head away from the hose 73 no longer fits into the inner wall of the wine spout head 722 for sealing, and the channel inside the wine spout seat 721 is connected with the channel inside the wine spout head 722 through the through hole on the sealing head, so that the passage in the wine spout 72 is opened, and the wine can flow out through the wine spout 72.

[0126] The gas charging and discharging assembly includes an air source, a solenoid valve, an air pipe 51 and an air intake core 52 .

[0127] The air source is fixedly mounted on the base 31 and electrically connected to the control module for inflating air into the inflation cavity between the wine barrel 10 and the inner bag.

[0128] In this embodiment, the air source is an air pump motor. This motor utilizes a low-noise, low-vibration miniature electric air pump embedded in a fixed rubber structure. This maintains constant pressure, significantly extending the wine's shelf life. The base 31 is equipped with a support for mounting the fixed rubber structure. The fixed rubber structure is screwed to the support, creating a gap between the air pump motor and the base plate of the base 31. This gap is filled with air pump shock-absorbing pads to reduce vibrations caused by the motor's operation.

[0129] The solenoid valve is provided on the base 31 , electrically connected to the control module and the gas source, and installed on the air pipe 51 , and is used to control the pressure in the inflation chamber and to deflate when the pressure is too high.

[0130] like Figure 13 As shown, the aluminum block mounting base 314 is fixedly connected to the wine barrel mounting bracket 313 via screws. An air intake core mount 3131 is fixedly mounted on the wine barrel mounting bracket 313, corresponding to the air passage 712 of the wine outlet top core 71. The air intake core mount 3131 has an internal passage for air circulation, and its bottom is connected to the air pipe 51. The air pipe 51 connects the air intake core mount 3131 and the air pump motor.

[0131] One end of the air intake core 52 is installed in the gas channel 712 of the wine outlet top core 71, and the other end is installed in the air intake core mounting seat 3131. The middle part of the air intake core 52 has a convex edge. The part of the air intake core 52 located at the upper end of the convex edge is inserted into the gas channel 712, and two sealing rings are provided on the outer wall of the upper end portion to seal with the gas channel 712; the part of the air intake core 52 located at the lower end of the convex edge is inserted into the air intake core mounting seat 3131, and a sealing ring is provided on the outer wall of the lower end portion to seal with the inner wall of the air intake core mounting seat 3131. In other words, the air intake core 52 connects the air intake channel 712 and the air intake core mounting seat 3131. The gas output by the air source passes through the air pipe 51, the air intake core mounting seat 3131, the air intake core 52, the gas channel 712 of the wine outlet top core 71, and the air intake passage in the wine spear 20 in sequence, and then enters the air intake cavity located between the barrel wall and the inner bag of the wine barrel 10.

[0132] A pressure sensor is also installed on the air pipe 51 to detect the pressure inside the air pipe 51, which is equivalent to detecting the pressure inside the inflation chamber. When the pressure sensor detects that the pressure between the wine barrel 10 and the inner bag is greater than the set maximum threshold, the control module controls the air source to stop inflation; when the pressure between the wine barrel 10 and the inner bag is less than the set minimum threshold, the control module controls the air source to inflate until the pressure inside the inflation chamber exceeds the set minimum threshold. In this embodiment, the set minimum pressure threshold is 0.3 bar, and the set maximum pressure threshold is 0.5 bar. That is, when the pressure inside the barrel is greater than 0.5 bar, inflation stops, and when the pressure inside the barrel is less than 0.3 bar, inflation continues.

[0133] like Figure 20 As shown, when the top cover 34 is closed on the lower part 32 of the shell, the upper hinge triggers the reed, and after the control module receives the signal that the pressure relief microswitch 325 is triggered, the control module controls the air source to inflate the inflation chamber; when the top cover 34 is rotated from the closed position on the lower part 32 of the shell to the open position, the upper hinge disengages from the reed of the pressure relief microswitch 325, and after the control module receives the signal that the pressure relief microswitch 325 is not triggered, the control module controls the solenoid valve to deflate the inflation chamber, so that the air pressure in the inflation chamber is less than 0.3 bar, so that the user will not be in danger due to excessive pressure in the barrel when taking down the wine barrel 10.

[0134] Figure 19 It is a partial enlarged view of the cross-sectional view of the beverage dispenser in the embodiment of the present invention near the base.

[0135] like Figure 13 and Figure 19 As shown, a drip tube connection portion 3132 is provided on the wine barrel mounting bracket 313 near the air intake core mounting seat 3131. The drip tube connection portion 3132 is used to collect wine that drips during the installation of the wine container 1. The bottom of the drip tube connection portion 3132 is connected to the drip tube 3133.

[0136] A drip elbow 36 is fixedly mounted at the front of the bottom end of the housing 30 and extends through the front of the housing 30. One end of the drip elbow 36, located inside the housing 30, is connected to the other end of the drip tube 3133. The other end of the drip elbow 36, located outside the housing 30, extends above the drip tray 35, allowing wine collected at the drip tube connection 3132 to flow through the drip tube into the drip tray 35.

[0137] Figure 21 It is a partial enlarged view of the liquid outlet component of the cross-sectional view of the beverage dispensing device in the embodiment of the present invention.

[0138] like Figure 21As shown, the liquid outlet assembly 60 includes a faucet fixing frame 61, a faucet rubber pad 62, a micro switch 63, a micro switch fixing plate 64, a faucet housing 65, a core shaft 66, a pressure block 67 and a handle 68.

[0139] A faucet mounting portion is provided at the center of the front top of the housing 30 , and a faucet fixing frame 61 is fixedly mounted on the faucet mounting portion for connecting and fixing other components of the liquid outlet assembly 60 .

[0140] The faucet rubber pad 62 is set in the groove of the limiting cover 33 for allowing the liquid outlet pipe 70 to pass through and installing the liquid outlet component 60, and a part of the hose 73 is embedded in the faucet rubber pad 62.

[0141] Microswitch mounting plate 64 is fixedly mounted on faucet mounting bracket 61, and microswitch 63 is fixedly mounted on microswitch mounting plate 64. The reed of microswitch 63 faces the front of the housing. Microswitch 63 is electrically connected to the control module and is used to control the air source 51 to inflate the air cavity. Specifically, once microswitch 63 is activated, the control module controls the air source 51 to inflate the air cavity.

[0142] The faucet housing 65 is fixedly mounted on the faucet mounting bracket 61 and comprises a first side cover 651, a second side cover, and a faucet cover 653. The first and second side covers 651 and 653 are symmetrically arranged, and the second side cover is fixedly mounted to the first side cover 651 via screws, forming a mounting base for the pressure block 66, the movable spindle 67, and the handle 68. The faucet cover 653 is rotatably mounted on the mounting base and partially encloses the mounting base from its top and the end facing away from the front of the housing 30.

[0143] The faucet cover 653 is rotatably connected to the mounting base via a rotating shaft. The rotating shaft is located at the bottom center of the mounting base slightly away from the front of the housing 30. The faucet cover 653 can rotate around 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 housing groove for mounting a hose 73 of the first sex tube 70 and a wine spout 72.

[0144] During the installation of the liquid outlet pipe 70, the user needs to open the faucet cover 653, that is, the faucet cover 653 needs to be rotated so that the shell groove of the mounting seat is exposed to the outside, so as to install the hose 73 of the liquid outlet pipe 70 and the wine spout 72 into the shell groove.

[0145] A rubber strip 655 is further provided on the faucet cover 653 near the front of the housing 30 , and the rubber strip is located between the faucet cover 653 and the mounting seat.

[0146] Magnets are also provided on the top of the first side cover 651 and the second side cover. Magnets are also provided on both sides of the rubber strip 655 of the faucet housing 65 so that the faucet housing 65 can be attracted by the magnets.

[0147] After the liquid outlet pipe 70 is installed, the faucet cover 653 is rotated so that the faucet cover 653 covers the shell groove on the mounting base again, and the rubber strip 655 can play a buffering role. At the same time, when the faucet cover 653 is rotated close to the rubber strip, the faucet cover will be attracted by the magnet and automatically closed on the mounting base.

[0148] A buckle 657 is also provided in the housing recess at the front end of the mounting base, that is, at the end of the mounting base away from the front of the housing 30. Buckle 657 engages with the outer wall of the spout head 722 of the liquid outlet tube 70. The front end of the housing recess is provided with a structure for securing the spout head 722, preventing it from moving toward the base 31.

[0149] The core shaft 66 is installed on the second cover plate, one end of which extends to the inside of the mounting seat, and the other end extends to the outside of the mounting seat, and is fixedly connected to the handle 68. A gasket is also provided between the handle 68 and the second cover plate. Figure 21 Turning the manual knob 68 counterclockwise as shown causes the spindle 66 to rotate counterclockwise.

[0150] The end of the core shaft 66 extending into the mounting seat is provided with a protrusion 662 extending in the radial direction of the core shaft 66. The mounting seat is also provided with a push rod 663 extending in the horizontal direction. The push rod 663 is movably mounted in the mounting seat. The end of the push rod 663 away from the front of the housing 30 has a circular hole compressed in the vertical direction. The protrusion 662 is inserted into the circular hole. The end close to the front of the housing 30 is provided corresponding to the contact of the micro switch 63. Figure 21 When the cover 66 is rotated in the clockwise direction, the protrusion 662 pushes the push rod 663 to move toward the front cover, pushing the reed to trigger the micro switch 63.

[0151] One end of the pressing block 67 is rotatably connected to the mounting base formed by the first side cover 651 and the second side cover, with this rotatable connection located near the front of the housing 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 toward the base 31. When the wine spout is installed in the housing recess of the mounting base of the liquid spout assembly 60, the end surface of the pressing block end 671 abuts against the end surface of the wine spout seat 721 of the wine spout 72, distal from the wine spout head 722.

[0152] The end of the mandrel 66 that extends into the mounting seat is provided with two mandrel connecting portions 664 extending radially from the movable mandrel. The protrusion 662 is located between the two mandrel connecting portions 664. The end of the mandrel connecting portion 664 that is remote from the mandrel 66 is provided with a through hole extending axially along the mandrel 66. The pressure block 67 also has a hole in the middle of its length that corresponds to the through hole in the mandrel connecting portion 664. A shaft passes through the through hole in the mandrel connecting portion 664 and the hole in the pressure block 67, connecting the mandrel 66 and the pressure block 67 together.

[0153] When the pressing block 67 is located at the initial position (i.e., not pressed down), the wine spout top core 723 blocks the wine spout seat 721 , the wine spout 72 is in a closed state, and the wine cannot flow out of the wine spout 72 .

[0154] When the handle 68 drives the core shaft 66 along Figure 21 When it rotates in the counterclockwise direction as shown, the pressing block 67 will also rotate in the counterclockwise direction, thereby pushing the wine outlet seat 721 of the wine outlet spout 72 to move toward the direction close to the wine outlet head 722, that is, the wine outlet top core 723 moves relatively in the opposite direction of the wine outlet seat 721, thereby opening the wine outlet 72. Under the action of the gas pressure filled in the inflation chamber, the wine in the inner bag flows along the wine outlet top core 71 and the hose 73 of the liquid outlet pipe 70 to the wine outlet 72, and then flows out from the outlet of the wine outlet 72.

[0155] A return spring (not shown) is provided at the bottom of the portion where the pressing block 67 is connected to the core shaft connection portion 664 (close to the base 31). One end of the return spring abuts against the mounting seat of the liquid outlet assembly 60, and the other end abuts against the bottom of the portion where the pressing block 67 is connected to the core shaft connection portion 664. Figure 21 When turned clockwise as shown, the return spring is compressed.

[0156] When the user finishes pouring the wine, he releases the handle 68, and the pressing block 67 moves along the Figure 21 Turn counterclockwise as shown to return to the original position.

[0157] Figure 22 1 is a schematic diagram of the process of using the beverage making device in an embodiment of the present invention.

[0158] like Figure 22 As shown, the specific process of installing the beverage dispenser and dispensing wine is as follows:

[0159] Step S1, take out a new liquid outlet pipe 70, install the wine outlet top core 71 of the liquid outlet pipe 70 onto the wine spear 20 of the wine barrel 10, and then proceed to step S2;

[0160] Step S2, open the rotating faucet cover 653 (i.e., along Figure 21 Rotate the faucet cover 653 in a clockwise direction to expose the housing groove on the mounting base of the liquid outlet assembly 60, clamp the hose 73 in the housing groove and the rubber pad groove 621, and clamp the wine outlet nozzle head 722 of the wine outlet nozzle 72 in the buckle 657, and then proceed to step S3;

[0161] Step S3: Open the top cover 34, and install the wine barrel 10 with the wine outlet top core 71 installed, with the wine spear facing downward, through the center of the cooling aluminum block 42, and onto the wine barrel fixing frame 313, so that the wine outlet top core 71 is opposite to the air inlet core 52. Then, clamp the hose 73 connected to the wine outlet top core 71 in the clamps of the hose mounting groove 3141 and the wine pipe clamping groove 431 in sequence, and then proceed to step S4;

[0162] Step S4: Close the top cover 34, causing the upper hinge 341 on the top cover 34 to press the reed of the pressure relief microswitch. Simultaneously, the power switch 322 is pressed, causing the control module to control the compressor 44, condenser 45, and fan to start refrigeration. The wine in the inner bag is cooled by the refrigeration aluminum block 43. Simultaneously, the control module controls the air source to inflate the inflation chamber, and then proceeds to step S5.

[0163] Step S5, place the wine glass under the liquid outlet component 60, turn the handle 68 to open the wine outlet 72, and the wine flows out through the wine outlet 72 under the pressure of the gas in the inflation chamber, thereby achieving wine dispensing and then entering the end state.

[0164] Example Function and Effect

[0165] The beverage making device provided in this embodiment has a beverage container and a dispenser. The beverage container is provided with an inner bag. The dispenser has an inflation component for inflating air between the inner bag and the beverage container and a refrigeration component for cooling the beverage in the beverage container. A accommodating portion and a liquid outlet pipe connected to the beverage container are provided in the shell. One end of the liquid outlet pipe is accommodated in the accommodating portion. The beverage container is engaged in the accommodating portion by external force so that the liquid outlet pipe is connected to the inner bag. Without the need for an additional locking mechanism or fixing mechanism, the purpose of connecting the inner bag and the liquid outlet pipe and fixing the beverage container can be achieved at the same time, making the installation of the beverage container more convenient and quick.

[0166] In addition, the wine spear of the beverage container is mounted on the aluminum block fixing base. The wine spear has an L-shaped clamping block, and the aluminum block fixing base has a clamping block that matches the L-shaped clamping block. The bottom surface of the clamping block, that is, the clamping surface, has an inclined portion, so that when the L-shaped clamping block is engaged with the clamping block, it rotates and moves downward at the same time. This structure is simple and easy to manufacture, and only a small rotation angle is required to achieve fixed installation of the beverage container, making operation easier.

[0167] In addition, the dispenser has a refrigeration component for accommodating a portion of the beverage container, which is used to refrigerate the beverage in the beverage container. The accommodating portion formed by the inner liner and the refrigeration aluminum block in the refrigeration component wraps at least two-thirds of the beverage container, resulting in a better refrigeration effect. In addition, there is also an air filling and deflation component for inflating and deflating the beverage container, which is used to inflate air between the inner bag and the wall of the beverage container. The beverage is contained in the inner bag, and the wine is squeezed out by filling air between the wine barrel and the inner bag. The wine is better airtight when contained in the inner bag, and after being filled with air, the air does not come into direct contact with the wine, which can prevent the wine from deteriorating due to air intake. The refrigeration component wraps the portion of the beverage container that corresponds to the beverage that is about to flow out, so that the beverage dispensed by the beverage dispenser can be kept at a preset low temperature as much as possible, thereby improving the taste of the beverage.

[0168] In addition, the overall shape of the beer dispenser in this embodiment is egg-shaped, the capacity of the beverage container is 3L, the structure is compact and exquisite, and it takes up little space, which is very suitable for home use, allowing users to enjoy low-temperature draft beer without going to bars and other places.

[0169] In addition, the inner bag is a multi-layer composite material with a certain light-shielding property. Since the wine barrel is made of transparent plastic, the wine will deteriorate rapidly if it is exposed to ultraviolet rays for a long time. Therefore, the light-shielding inner bag can prevent ultraviolet rays from directly exposing the wine, thereby greatly delaying the deterioration of the wine.

[0170] In addition, the refrigeration assembly includes a refrigeration aluminum block and an insulation layer wrapped around the outside of the refrigeration aluminum block. A condenser groove for installing a condenser is also provided on the outer wall of the refrigeration aluminum block, and the refrigeration aluminum block wraps around a portion of the beverage container. The refrigeration aluminum block is cooled by the coolant in the condenser in conjunction with the compressor, refrigerator, and fan. Due to the good thermal conductivity and low density of aluminum, as a material in direct contact with the beverage container, it can increase the cooling speed of the beverage in the beverage container, improve the cooling efficiency of the beverage making device, and reduce the weight of the beverage making device. The insulation layer is made of foam. By wrapping the refrigeration aluminum block with the insulation layer, the aluminum block can be prevented from being affected by the ambient temperature, thereby maximizing the cooling effect.

[0171] In addition, a hose clamp is provided on the refrigeration aluminum block, and the hose of the liquid outlet pipe is stuck in the wine pipe clamp to prevent the hose from being displaced or squeezed and stuck by the gas components of the beverage device, which would prevent the wine from flowing out.

[0172] In addition, a temperature sensor that is in close contact with the outer wall of the beverage container is installed on the refrigeration aluminum block. The control module is electrically connected to the temperature sensor, the refrigerator, and the compressor. The temperature sensor detects the temperature of the outer wall of the beverage container, which is equivalent to detecting the temperature of the beverage therein. This allows the beverage making device of this embodiment to automatically control the refrigerator for cooling according to the detected beverage temperature, thereby keeping the beverage in the beverage container within a pre-set suitable low temperature range, achieving intelligent constant temperature, and ensuring the taste of the beverage.

[0173] In addition, the control module is connected to the gas source and the solenoid valve. By detecting the gas pressure in the inflation chamber of the beverage container, it controls the gas source for inflation and controls the solenoid valve for deflation, so that the gas in the inflation chamber is maintained within a constant pressure range. Every time the user presses the handle, the beverage device can smoothly dispense beverages.

[0174] In addition, in this embodiment, a liquid discharge pipe is connected to the beverage container to dispense wine. The liquid discharge pipe includes a wine discharge top core connected to the wine lance of the wine barrel, a hose, and a wine discharge spout. The liquid discharge pipe is a replaceable component. Whenever the beverage container in the beverage dispensing device is replaced, the liquid discharge pipe can be replaced at the same time. This prevents wine residue in the discharge pipe and eliminates the need to clean the discharge pipe, thereby improving hygiene.

[0175] In addition, a pressure relief microswitch is provided on the lower hinge at the lower part of the shell, and the microswitch cooperates with the upper hinge on the top cover to be triggered. When the top cover is closed on the lower part of the shell, the reed on the pressure relief microswitch is pressed, and the control module controls the gas source to fill the inflation chamber with gas. When the top cover is opened, the reed on the pressure relief microswitch is not pressed, and the control module controls the solenoid valve to deflate the inflation chamber. That is to say, as long as the user opens the top cover, the high-pressure gas in the beverage container begins to be discharged until the pressure in the beverage container is less than 0.3 bar, thereby ensuring the safety of the user when replacing or removing the beverage container.

[0176] In addition, the dispenser is provided with a liquid outlet assembly, and the handle, core shaft, pressing block and wine outlet nozzle of the liquid outlet pipe on the liquid outlet assembly cooperate with each other.
