[0021] like Figure 1-Figure 4As shown, the bulk liquid automatic vending device provided in this embodiment includes a vending cabinet 1, wherein the vending cabinet 1 is divided into a normal temperature commodity vending area 11, a liquid receiving container vending area 12 and a constant temperature commodity vending area 13, wherein the liquid receiving container vending area 12 is placed between the normal temperature commodity vending area 11 and the constant temperature commodity vending area 13, and is composed of a plurality of container placement compartments 131 and a pickup port 132, wherein a plurality of liquid receiving containers 5 are placed in each container placement compartment 131; a commodity storage compartment 2 is provided at the upper end of the normal temperature commodity vending area 11 and the constant temperature commodity vending area 13, and a thermostat for controlling the temperature of the commodity storage compartment 2 is installed in the commodity storage compartment 2 of the constant temperature commodity vending area 13 Device (specifically, the constant temperature device includes a heating device and a condenser), at least one liquid storage cylinder 3 is fixedly installed in each commodity storage compartment 2, and a liquid receiving chamber 4 for placing a liquid receiving container 5 is provided under each commodity storage compartment 2; the liquid outlet pipe 31 of each liquid storage cylinder 3 is extended out of the storage compartment and placed in the liquid receiving chamber 4, and an electromagnetic valve 32 is provided on the liquid outlet pipe 31; a dustproof cabinet door 44 is rotatably installed at the opening at the front end of the liquid receiving chamber 4, and the bottom plate of the liquid receiving chamber 4 is a pull-out plate 41 (a slide rail is provided on the side wall of the liquid receiving chamber 4, and a ball slider matching the slide rail is provided on the left and right sides of the pull-out plate 41), which can be pulled and positioned along the width direction of the liquid receiving chamber 4 under the action of external force.

[0022] In this way, after setting up the normal temperature commodity sales area 11 and the constant temperature commodity sales area 13, different liquid commodities can be classified and placed according to their storage conditions, thereby providing different storage environments for different commodities and ensuring that the quality of the commodities is not affected by the ambient temperature. The liquid receiving container sales area 12 provided can be used to sell liquid receiving containers 5, so that consumers who do not carry containers can purchase corresponding liquid receiving containers 5 as needed. The constant temperature device installed in the constant temperature commodity sales area 13 can adjust the temperature of the commodity storage compartment 2 according to the requirements of the commodity storage environment, which is conducive to the storage of commodities. The liquid receiving chamber 4 provided is arranged adjacent to the commodity storage compartment 2, which can effectively shorten the length of the liquid outlet pipe 31. At the same time, the liquid receiving chamber 4 is provided with a dustproof cabinet door 44, which can effectively ensure that the liquid receiving chamber 4 is isolated from the outside air during use and when idle, and the liquid receiving pipe is not exposed to the outside, and the sanitary conditions are better, which is safer and more sanitary for bulk products such as food that have high sanitary requirements. The bottom plate of the liquid receiving chamber 4 is set as a pull-out plate 41, which can be pulled out when taking and placing the liquid receiving container 5, making it convenient to take and place. When liquid needs to be received, the bottom plate is drawn into the liquid receiving chamber 4, so that the liquid receiving container 5 corresponds to the liquid outlet pipe 31, and then the liquid is discharged.

[0023] In specific implementation, the payment code of the liquid receiving container 5 of this category can be directly posted at the different container placement compartments 131. After the consumer pays, the delivery structure in the existing vending machine is used to push the liquid receiving container 5 in the corresponding container placement compartment 131 to the delivery port. Of course, it is also possible to directly set a cabinet door in the corresponding container placement compartment 131, set a one-way valve in each container placement compartment 131, set a pushing mechanism at the end away from the cabinet door, and set a payment code on each cabinet door; when the customer scans the code to pay, the door lock of the cabinet door is automatically opened, and the pushing mechanism pushes the liquid receiving container 5 at the front end through the one-way valve to the front end for the customer to take, and the customer closes the cabinet door after taking it.

[0024] In a specific implementation, the structure of the dustproof cabinet door 44 can be implemented in the following two ways:

[0025] The left or right side of the dustproof door 44 is rotatably connected to the liquid receiving chamber 4. A magnet is provided in the liquid receiving chamber 4. A metal block matching the magnet is embedded in the dustproof door 44. A transparent window 45 corresponding to the liquid outlet pipe 31 is provided in the middle of the dustproof door 44. In this way, the dustproof door 44 is a side-opening door, and after the metal block is provided on it, when the dustproof door is closed, the metal block and the magnet are adsorbed together to achieve closing the door, and the door can be opened under the action of external force. The transparent window 45 provided on the dustproof door 44 can observe the docking of the liquid outlet pipe 31 and the liquid receiving nozzle of the liquid receiving container 5, and can also observe the liquid level at the upper end of the liquid receiving container 5. The lower end of the dustproof door is higher than the upper end surface of the pull-out plate 41, which can avoid interference between the dustproof door and the pull-out plate.

[0026] The dustproof cabinet door 44 is composed of an upper fixed door panel 441 and a flap 442 whose upper end is rotatably mounted on the lower end of the upper fixed door panel 441. A transparent window 45 corresponding to the liquid outlet pipe 31 is provided on the upper fixed door panel 441, a pull rod with a hanging hole is provided on the outer side of the flap 442, and a hook for hanging the pull rod is provided on the fixed door panel. In this way, the dustproof cabinet door 44 is fixed at the upper end and has a flap 442 at the lower end. When in use, the liquid receiving chamber 4 can be opened by rotating the flap 442 upwards, and the liquid receiving chamber 4 can be formed into a closed space after being flipped downwards.

[0027] Furthermore, a transparent portion 21 and a touch screen 22 are provided on the front face of each commodity storage compartment 2, a weighing scale 24 is provided at the lower end of each liquid storage cylinder 3, and a control processing device 23 is provided in each commodity storage compartment 2. The weighing scale 24, the touch screen 22 and the solenoid valve 32 are all connected to the control processing device 23; the touch screen 22 has a built-in input module, a display module and a payment module, and the control processing device 23 includes a communication module and a processor. The communication module is mainly used to receive information and send instructions, and the processor is connected to the communication module, the input module, the display module and the payment module. In this way, the transparent portion 21 of the commodity storage compartment 2 can facilitate the purchaser to intuitively see the quality of the liquid commodity in the commodity storage compartment 2, and the touch screen 22 can be used by consumers to select the required purchase volume, select the payment method, etc. The weighing scale 24 provided under the liquid storage cylinder 3 can weigh the liquid in the liquid storage cylinder 3 in real time, and output the weighing result to the control processing device 23, which issues corresponding control instructions according to the real-time weighing result and the liquid weight required by the consumer. The weight transmitter receives the signal of the pressure sensor installed under the weighing plate and converts it into weight, which is then uploaded to the control processing device 23 for data calculation based on the type and concentration of the goods being sold, and converted into capacity. In specific implementations, other methods can also be used to control the precise liquid output of each liquid outlet pipe 31, such as the liquid output metering system of the liquid vending machine disclosed in the Chinese patent application number 201620491144.6, and the liquid output metering mechanism in the bulk liquid automatic vending control system disclosed in the Chinese patent application number 201921570775.7.

[0028] According to the use requirements, when the height and size of the liquid receiving container 5 carried by the consumer are inconsistent, and at the same time, the height and size of the corresponding liquid receiving container 5 sold are also inconsistent according to the different capacities, based on this, when the liquid receiving container 5 is placed in the liquid receiving chamber 4, the distance between the liquid receiving nozzle of the liquid receiving container 5 and the liquid outlet of the liquid outlet pipe 31 will be inconsistent. If the liquid receiving nozzle is too far away from the liquid outlet, it is easy to spill the sold liquid outside. In addition, for easily volatile bulk liquids such as white wine, it is best to place the liquid receiving container 5 close to the liquid outlet or set it before discharging the liquid. In summary, in order to avoid the problem of too large a distance between the liquid receiving nozzle and the liquid outlet, a step hole is provided in the middle of each pull-out plate 41, and a container support plate 43 that can be moved up and down and positioned under the drive of a lifting mechanism 7 is embedded in the step hole. In each liquid receiving chamber 4, an infrared sensor 6 is provided at a height position close to the outlet of the liquid outlet pipe 31, and each infrared sensor 6 and the lifting mechanism 7 are connected to the corresponding control processing device 23. After adopting the above arrangement, the container support plate 43 arranged in the middle of the draw plate is embedded in the draw plate 41, so that after being lifted by the lifting mechanism 7, the liquid receiving container 5 placed thereon can be driven to rise together. The infrared sensor 6 arranged can send a signal to the control processing device 23 after the liquid receiving nozzle of the liquid receiving chamber 4 rises to the vicinity of the liquid receiving pipe. After receiving the corresponding signal, the control processing device 23 can send a command to the lifting mechanism 7 to stop rising.

[0029] Furthermore, the lifting mechanism 7 is a lifting cylinder, which is placed at the lower end of the liquid receiving chamber 4. The lifting cylinder is connected to the control processing device 23. A positioning sleeve is provided at the bottom of the container support plate 43. The cylinder rod of the lifting cylinder corresponds to the positioning sleeve and can be sleeved with the positioning sleeve when rising, and detached from the positioning sleeve after falling. In this way, the lifting cylinder is small in size and can achieve lifting and positioning. In a specific implementation, a screw lifting mechanism 7 or the like can be used. The positioning sleeve provided on the container support plate 43 can be sleeved with the cylinder rod and detached under external force.

[0030] Furthermore, each container placement compartment 131 is used to place liquid receiving containers 5 of different capacities and materials; the pickup port 132 is located at the lower end of the liquid receiving container sales area 12. In this way, customers can choose corresponding liquid receiving containers 5 according to their different needs, and the pickup port 132 is provided at the lower end of the liquid receiving container 5, which can facilitate the removal of the liquid receiving container 5.

[0031] Furthermore, a flexible positioning block 24 is provided on the inner wall of the commodity storage compartment 2, the inner side of which abuts against the outer wall of the liquid storage tube 3. In this way, the flexible positioning block 24 can firmly fix the liquid storage tube 3, so as to prevent the liquid storage tube 3 from shaking during transportation or after the electromagnetic valve 32 on the liquid outlet pipe is opened to allow liquid to flow out.

[0032] Further, a handle 42 is provided on the front end surface of the pull-out plate 41. In this way, the provided handle 42 facilitates the user to pull the pull-out plate 41.

[0033] Furthermore, an infrared emitting ring 33 is sleeved near the mouth of the liquid outlet pipe 31 and is concentric with the liquid outlet pipe 31. The infrared emitting ring 33 can emit a ring-shaped infrared indicator line downward after being connected to an external power source. In this way, after the infrared emitting ring 33 emits the infrared indicator line, it is convenient for consumers to determine the position of the liquid outlet pipe 31 according to the infrared indicator line after placing the liquid receiving container 5, so as to adjust the position of the liquid receiving container 5 in real time, ensure that the liquid receiving nozzle of the liquid receiving container 5 corresponds to the liquid outlet of the liquid outlet pipe 31, and prevent liquid leakage.

[0034] In order to facilitate the real-time replenishment of corresponding liquid products, a liquid inlet pipe may be further provided on each liquid storage cylinder 3. A liquid level sensor and an alarm module are arranged on the liquid storage cylinder 3 in this embodiment. When the liquid level is low, the liquid level sensor sends a signal to the alarm module, and the alarm module sends an alarm message to the control processing device 23. After the control processing device 23 receives the information through the communication module, it sends an information prompt for replenishing liquid products to the back-end management personnel through the communication module.

[0035] For ventilation, multiple vents are also provided on the side of the normal temperature commodity sales area 11. For the convenience of the backstage management personnel to replenish liquid commodities to the liquid storage cylinder 3, a liquid replenishing tube is also provided on the liquid storage cylinder 3, and the backboard of the commodity storage compartment 2 can be opened and locked.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
