[0061] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0062] It is worth explaining that an empty beer bottle refers to an empty beer bottle with a cover on the mouth, and a beer bottle refers to a bottle that has been filled with beer.

[0063] like Figure 1 to Figure 2 As shown, the integrated isobaric filling fresh beer self-service vending machine includes a cabinet 100, which is equipped with a bottle dropping mechanism, a beer isobaric filling mechanism, a water cooling unit, a single-chip control system and a software system; the single-chip control system is respectively connected to the bottle dropping mechanism, the beer isobaric filling mechanism, the water cooling unit and the software system, and the software system is respectively connected to the payment system and the backend management system; the backend management system is mainly responsible for equipment management, personnel management, payment management and collection of consumption receipts, etc. The software system is also connected to an advertising system, which can place picture or video advertisements through the advertising system to display and spread information to users.

[0064] In the present invention, the software system is the Android system.

[0065] The bottle dropping mechanism includes a storage box 11 for placing empty beer bottles 112, a bottle bottom supporting plate device 13 and a bottle dropping blocking device 14. A bottle receiving bucket 12 is provided below the bottle bottom supporting plate device 13. Under the control of the single-chip control system, the bottle bottom supporting plate device 13 and the bottle dropping blocking device 14 cooperate with each other to make the empty beer bottles 112 fall into the bottle receiving bucket 12. Under the control of the single-chip control system, the ice beer cooled by the water cooling unit 22 is filled into the empty beer bottles 112 through the beer isobaric filling mechanism 21.

[0066] like Figures 2 to 4As shown, the cabinet 100 includes a left cabinet, and a roughly rectangular storage box 11 is placed on the upper layer of the left cabinet. The bottom and front of the storage box 11 are both provided with openings. A plurality of columns of storage areas are separated by bottle partitions 111 in the storage box 11, and a plurality of empty beer bottles 112 are vertically stacked in each column of the storage area. A detection switch 113 is respectively provided at the two inner bottom ends of the storage area, and the detection switch 113 is used to detect whether there are empty beer bottles 112 in the current storage area.

[0067] Furthermore, a bottle receiving bucket 12 with a front opening is provided below the storage box 11 for accommodating empty beer bottles 112. A bottle falling protection door 102 is provided on the left cabinet door. The bottle falling protection door 102 is hinged to the bottle receiving bucket 12. The user can take out the empty beer bottles 112 by opening the bottle falling protection door 102. The bottle falling protection door 102 can prevent the empty beer bottles 112 from falling and popping out of the cabinet 100, thereby ensuring the hygiene of the empty beer bottles 112 and protecting the empty beer bottles 112 from damage.

[0068] like Figures 2 to 5 As shown, a bottle bottom support plate device 13 is further provided between the storage box 11 and the bottle receiving bucket 12. The bottle bottom support plate device 13 is opened or closed under the control of the single-chip control system so that the empty beer bottle 112 falls into the bottle receiving bucket 12. Specifically, the bottle bottom support plate device 13 includes a first motor 131, a rack 132, an optical axis seat device 133 and a support plate 134. The two optical axes are fixed to the cabinet 100 in parallel through the optical axis seat. The bottom of the support plate 134 is sleeved on the optical axis. The rack 132 is fixed to the inner side of the support plate 134. The output shaft of the first motor 131 is meshed with the rack 132 through a gear. Driven by the first motor 131, the support plate 134 slides back and forth along the optical axis so that the empty beer bottle 112 falls into the bottle receiving bucket 12.

[0069] Furthermore, a first sensing sheet 135 is provided on the inner side of the support plate 134, and a plurality of first photoelectric switches 136 are provided on the rear side of the storage box 11. When the first sensing sheet 135 contacts one of the first photoelectric switches 136, the support plate 134 stops sliding to allow the empty beer bottles 112 in the current accommodating area to fall.

[0070] like Figures 2 to 6 As shown, the present invention is provided with a bottle-falling blocking device 14 at the rear of the storage box 11, and the bottle-falling blocking device 14 is used to block the empty beer bottles 112 above the bottom layer from falling. The bottle-falling blocking device 14 comprises a fixing seat 141, a screw motor 142, a slide rail 143 and a blocking member 144, the screw motor and the slide rail 143 are fixed on the fixing seat 141, the end of the screw motor is connected to the blocking member 144, a slider 145 is fixed to the bottom of the blocking member 144, and the slider 145 is connected to the slide rail 143. Under the drive of the screw motor 142, the blocking member 144 slides along the slide rail 143, so that the blocking member 144 can enter and exit each column of the accommodating area.

[0071] Furthermore, a second sensing sheet 146 is provided on the blocking member 144, and second photoelectric switches 147 are provided at the front and rear ends of the side of the fixing seat 141. When the second sensing sheet 146 contacts one of the second photoelectric switches 147, the blocking member 144 stops moving. The second photoelectric switch 147 mainly serves to limit the starting position of the blocking member 144.

[0072] like Fig.13 As shown, the implementation process of the bottle dropping of the present invention (taking the bottle dropping in the second row of the receiving area as an example):

[0073] Before the single-chip control system issues a bottle-dropping instruction, the bottle bottom support plate device is located at the first origin (i.e., the bottle bottom support plate is closed), and the bottle-dropping blocking device is located at the end point (i.e., the blocking member does not extend into the accommodating area). The single-chip control system controls the detection switch 113 to sequentially detect whether there are empty beer bottles 112 in the multiple columns of accommodating areas. For example, if an empty beer bottle 112 is detected in the second column of accommodating areas, the bottle-dropping position 2 is recorded as the memory point, and the bottle-dropping position 1 is recorded as the memory origin.

[0074] Then the bottle-falling blocking device is controlled to move to the second origin (i.e. the blocking member 144 extends into the accommodation area), the single-chip control system reads the memorized bottle-falling position and controls the first motor 131 to operate, driving the support plate 134 to move to the memorized origin (i.e. bottle-falling position 1);

[0075] The single-chip control system controls the first motor 131 to reverse and drive the support plate 134 to move to the memory point (i.e., bottle drop position 2). At this time, the outlet of the first column storage area is opened, and the empty beer bottles at the bottom end fall into the bottle receiving bucket. The single-chip control system controls the first motor 131 to operate and drives the support plate 134 to move to the first origin. At this time, the outlet of the first column storage area is closed; the single-chip control system continues to control the screw motor 142 to operate, and the blocking member 144 returns to the end point under the drive of the screw motor 142. At this time, the empty beer bottles 112 in the first column storage area move down one layer, completing a bottle drop process. After the empty beer bottles 112 in the first column are dropped, the empty beer bottles 112 in the second and third columns of storage areas are dropped in sequence, and so on, until all the empty beer bottles 112 in the storage box 11 are dropped. When the detection switches 113 in all storage areas do not detect empty beer bottles 112, the single-chip control system issues an alarm to prompt that there are no empty beer bottles 112 in the storage area.

[0076] It is worth noting that if the detection switch 113 detects that there are empty beer bottles in the third column storage area, the bottle drop position 3 is recorded as the memory point, the bottle drop position 2 is recorded as the memory origin, and so on. This setting reduces the movement stroke of the bottle bottom support device, thereby accelerating the bottle drop process.

[0077] like Figure 2 , Figure 7As shown, the cabinet 100 also includes a right cabinet, the upper layer of the right cabinet is provided with a filling area, the beer isobaric filling mechanism is arranged at the bottom plate of the filling area, a bracket is arranged below the bottom plate, and an inclined drip tray 216 is arranged at the bottom of the bracket, and the drip tray 216 is connected to the waste liquid collection bucket. The liquid dripping from the filling head can be collected into the waste liquid collection bucket through the drip tray 216 to keep the filling area clean. The lower layer of the right cabinet is provided with a carbon dioxide tank, a waste liquid collection bucket and a plurality of beer barrels of different flavors.

[0078] Furthermore, detection switches 113 are provided on both sides of the bracket for detecting whether there are empty beer bottles 112 in the filling area.

[0079] The beer isobaric filling mechanism includes a filling head 211, a lifting assembly fixed on the filling head, and a moving assembly arranged below the filling head, and an empty beer bottle is placed on or sleeved on the moving assembly; the filling head 211 includes a silicone sealing pad, an air inlet and an air outlet, and the silicone sealing pad is embedded in the bottom of the filling head 211, and a through hole for accommodating the air inlet is provided in the middle thereof, and the through hole is connected to the exhaust port.

[0080] Furthermore, the moving assembly in the present invention is a hanging plate 212 structure, and the user hangs the empty beer bottle 112 on the notch of the hanging plate 212. The lifting assembly includes an electric cylinder 214, a guide assembly 213 and a guide shaft 215. The top of the guide shaft 215 is respectively fixed to the two ends of the guide assembly 213, and the bottom thereof is respectively fixed to the two ends of the hanging plate 212. After the electric cylinder 214 is driven, the lifting assembly drives the hanging plate 212 with the empty beer bottle 112 to rise or fall.

[0081] like Fig.11 As shown, further, the beer isobaric filling mechanism can accommodate beer kegs of different flavors. The inlet of each beer keg is connected to the carbon dioxide tank, and its outlet is provided with a one-to-one beer outlet valve, each beer outlet valve is connected to the air inlet of the filling head through a beer pipeline, a flow meter is also provided in the beer pipeline, and a pressure sensor is also connected to the air outlet of the filling head; the carbon dioxide tank is connected to the beer pipeline through a pre-pressure air valve, and the single-chip microcomputer control system controls the opening or closing of each valve through the data measured by the flow meter and the pressure sensor, controls the beer output, and realizes that the flow rate and flow velocity of the beer in the filling process are controllable.

[0082] Furthermore, in order to prevent the beer from foaming and contaminating the filling area after filling, the air outlet of the filling head is connected to a liquid storage tank, and the liquid storage tank is respectively connected to a straight exhaust valve, a pressure exhaust valve, a drain valve and a liquid level switch. After the beer filling is completed, the beer outlet valve is closed, and the straight exhaust valve and the pressure exhaust valve are opened to intermittently exhaust the residual air in the beer bottle, and the excess beer is discharged through the drain valve under the control of the liquid level switch.

[0083] Furthermore, in order to obtain beer with a pure taste, the beer isobaric filling mechanism also includes a residual gas valve, and the carbon dioxide tank is connected to the beer pipeline through the residual gas valve. After the beer is filled, the single-chip control system controls the residual gas valve to open, so that the gas in the carbon dioxide is input into the filling head through the beer pipeline, thereby blowing the residual beer inside the beer pipeline into the empty beer bottle 112, cleaning the beer pipeline and the filling head.

[0084] Furthermore, in order to ensure the safety and sanitation of the pipeline and the filling head, the beer isobaric filling mechanism is also provided with a cleaning structure, which includes a disinfectant valve connected to the wine pipeline, a spray liquid valve connected to the filling head, and a spray air blowing valve connected to the filling head. The disinfectant valve and the spray liquid valve are both connected to the disinfectant barrel through a diaphragm pump, and the spray air blowing valve is connected to the carbon dioxide tank. After the completion of beer filling, there will be residual liquid in the wine pipeline and the filling head. If these residual liquids are not cleaned, it is easy to breed bacteria, affecting food safety. The present invention opens the spray liquid valve and the disinfectant valve after each filling, so that the disinfectant in the disinfectant barrel flushes the wine pipeline and the filling head for a period of time, thoroughly disinfects the wine pipeline and the filling head, and then dries the filling head through the spray air blowing valve to keep the filling head clean.

[0085] like Figure 8 As shown, the water cooling unit 22 is placed behind the filling area and connected to the filling area. The water cooling unit 22 can provide iced beer. Specifically, the water cooling unit 22 includes a water tank 221 and a refrigeration compressor unit. The water tank 221 contains water, a copper tube 222, and multiple beer barrels 223 (barrel one, barrel two, etc.). After the refrigerant is compressed by the compressor unit, the medium in the copper tube 222 vaporizes and absorbs the heat of the water in the water tank 221. After the water in the water tank 221 exchanges heat with the barrel, iced beer can be obtained. It is worth noting that the structure and refrigeration principle of the refrigeration compressor unit of the present invention are prior art and will not be described in detail here.

[0086] like Fig.11 As shown, the filling process of the present invention:

[0087] The user places the empty beer bottle 112 on the hanging plate 212 in the filling area, and the single-chip control system controls the lifting assembly to drive the hanging plate 212 to rise until the mouth of the empty beer bottle 112 on the hanging plate 212 hits the silicone sealing pad at the bottom of the filling head 211. The silicone sealing pad seals the mouth of the empty beer bottle 112, and the single-chip control system controls the pre-compression valve to open, so that the carbon dioxide in the carbon dioxide tank is injected into the empty beer bottle 112 from the air inlet of the filling head. When the air pressure in the empty beer bottle 112 is the same as the air pressure in the beer barrel, the single-chip control system controls the pre-compression valve to open, so that the carbon dioxide in the carbon dioxide tank is injected into the empty beer bottle 112 from the air inlet of the filling head. The control system controls the pre-compression valve to close and opens the beer outlet valve. Since the pressure of the wine barrel and the empty beer bottle 112 is equal, the beer in the beer barrel will not be poured into the empty beer bottle 112. At this time, the single-chip control system controls the opening of the exhaust valve on the filling head to gradually release the pressure of the empty beer bottle 112. The pressure inside the empty beer bottle 112 will decrease. The ice beer in the water cooling unit 22 is pushed by the pressure in the wine barrel and slowly injected into the empty beer bottle 112, and flows down along the inner wall of the empty beer bottle 112 until the empty beer bottle 112 is filled. Because the pressure difference is small, basically no foam will be generated. At the same time, the flow rate of beer is controlled by controlling the pressure difference, so that the flow rate of beer can be controlled during the filling process. Users can drink iced fresh beer with a pure taste.

[0088] like Fig. 9 As shown, in the present invention, a protective door structure 104 is also provided on the right cabinet door, and the protective door structure 104 corresponds to the support position of the filling area, and the protective door structure 104 includes a filling area protective door 1041, a second motor 1042, a rack 1043, a slide rail 1044, a slider 1045, a sensor 1046 and a micro switch 1047. The output shaft of the second motor 1042 is meshed with the rack 1043, and the rack 1043 and the filling area protective door 1041 are fixed on a fixed plate, and a slider 1045 is fixed on the fixed plate, and the slider 1045 is connected to the slide rail 1044. After the second motor 1042 is started, it drives the rack 1043 to move, and at the same time, the filling area protective door 1041 slides along the slide rail 1044. When the sensor 1046 on the filling area protective door 1041 senses a micro switch 1047 on the right cabinet door, it stops sliding, and at this time, the protective door is opened. When the filling area protection door 1041 needs to be closed, the motor runs to bring the filling area protection door 1041 back along the original path, and the other micro switch 1047 stops sliding after sensing the position.

[0092] Step 1. Screen standby state: When there is no purchase request instruction, the self-service vending machine is in standby state.

[0093] Step 2. Wake up and start: the user clicks the touch screen and rotates the beer flavor. The software system communicates with the payment system, the single-chip control system and the background management system respectively, and each system is ready.

[0094] Step 3. Equipment self-check: The single-chip microcomputer control system confirms whether there is any fault in the operating mechanism of the vending machine. If there is a fault, an alarm prompt will be displayed on the screen. If there is no fault, the payment system will send a payment request and wait for the user to complete the payment. After the payment is completed, the next step will be executed.

[0095] Step 4. Bottle dropping mechanism drops bottles: The single-chip control system sends a bottle dropping command, and the bottle dropping mechanism starts dropping bottles and confirms whether the bottle dropping is completed. If the bottle dropping is unsuccessful, the screen prompts a fault message and refunds. If the bottle dropping is successful, the user takes the empty beer bottle, the protective door of the filling area opens, and the screen prompts to unscrew the bottle cap of the empty beer bottle and hang the empty beer bottle on the filling head of the filling area.

[0096] Step 5. Isobaric filling of fresh beer: The single-chip microcomputer control system confirms whether the bottle hanging in the filling area is successful. If unsuccessful, the user manually adjusts the position of the empty beer bottle and the filling head. If successful, the defense door of the filling area is closed, and the single-chip microcomputer control system confirms the flavored wine route and sends a wine filling instruction, and the beer isobaric filling mechanism starts filling.

[0097] Step 6. The single-chip microcomputer control system confirms whether the beer dispensing is completed. If the beer dispensing is completed, the screen prompts that the beer dispensing is completed, the protective door of the filling area opens, and the user takes the filled fresh and chilled beer. If the beer dispensing is not completed, the screen displays a fault status and notifies the payment system to execute the refund process.

[0098] Step 7. The microcontroller controls the filling area protection door to close, the screen prompts that the filling is completed, and the vending machine enters standby mode, waiting for users to purchase.

[0099] like Figure 13 to Figure 14 As shown, in one embodiment, in the above self-service vending method, the bottle dropping control process of the bottle dropping mechanism includes the steps of:

[0100] Step 21. Self-inspection of bottle dropping mechanism: Check whether the internal components of the bottle dropping mechanism are ready. If abnormal, an alarm will be issued on the screen; if normal, the bottle bottom support plate device returns to the first origin (the bottle bottom support plate is closed), the bottle dropping blocking device returns to the end point (the blocking member is retracted), and then waits for the empty beer bottles to fall to the bottom of the storage box.

[0101] Step 22. Check whether there are empty beer bottles in each storage area: the detection switch checks whether there are empty beer bottles in each column of storage areas in sequence. If there are empty beer bottles in one column of storage areas, the bottle drop position is memorized. If there are no empty beer bottles in each storage area, an alarm will be issued on the screen to prompt that there are no empty beer bottles in the storage area.

[0102] Step 23. The bottle bottom support plate device moves to the memory origin: the single-chip microcomputer control system controls the bottle drop blocking device to return to the second origin (the blocking member extends), the single-chip microcomputer control system reads the memory bottle drop position, and controls the bottle bottom support plate device to move to the memory origin.

[0103] Step 24. Bottle dropping: When the single-chip microcomputer control system confirms that the bottle is to be dropped, it controls the bottle bottom support plate device to move to the memory point and waits for the empty beer bottle at the bottom to fall into the bottle receiving bucket.

[0104] Step 25. The bottle bottom support plate device returns to the first origin: the single-chip microcomputer control system controls the bottle bottom support plate device to move to the first origin, and the bottle falling blocking device returns to the end point. At this time, the empty beer bottles in the column accommodating area are moved down.

[0105] Step 26. End: Wait for the next bottle drop instruction and repeat the above steps.

[0106] It is worth noting that, during the above-mentioned bottle dropping process, if it is detected that there are empty beer bottles in the third column storage area, the bottle dropping position 2 is recorded as the memory origin, and the bottle dropping position 3 is recorded as the memory point.

[0107] like Fig.15 As shown, in one embodiment, in the above self-service vending method, the beer dispensing control process of the beer isobaric filling mechanism includes the following steps:

[0108] Step 41.

[0109] Step 42. Inflate the empty beer bottle: The single-chip control system controls the opening of the pre-compression valve to allow carbon dioxide to be injected into the empty beer bottle from the filling head. When the air pressure in the empty beer bottle is the same as the air pressure in the beer barrel, the pre-compression valve is closed;

[0110] Step 43. Beer isobaric filling mechanism fills beer: the single-chip microcomputer control system controls the opening of the beer outlet valve of the beer route selected by the user and the exhaust valve of the filling head, so that the pressure in the empty beer bottle is gradually released and the beer in the beer barrel flows into the empty beer bottle;

[0111] Step 44. Slow exhaust and intermittent exhaust in the bottle: When the beer output from the beer barrel reaches the preset value, the single-chip microcomputer control system closes the beer outlet valve of the corresponding beer circuit, opens the pressure relief valve and the straight exhaust valve, and exhausts the air in the beer bottle to below 10Kpa.

[0112] Step 45. Exhaust residual gas from pipeline: The single-chip microcomputer control system controls the opening of the residual gas valve to discharge the residual beer in the beer pipeline and the filling head;

[0113] Step 46. Beer bottle descends: the single chip control system controls the lifting assembly to descend, and the bottle filled with cold beer leaves the filling head;

[0114] In one embodiment, in the above-mentioned self-service vending method, the filling head cleaning control process: the single-chip control system opens the spray liquid valve and the disinfectant valve, the disinfectant in the disinfectant barrel flushes the wine pipeline and the filling head for a period of time, and then controls the opening of the spray air blowing valve to dry the filling head to keep the filling head clean.

[0115] It is worth noting that the filling area protection door of the present invention is automatically opened and closed by a single-chip microcomputer control system. In other embodiments, the user can open or close the filling area protection door according to the operating instructions prompted by the screen.

[0116] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
