Description

Technical Field

[0001] This utility model belongs to the technical field of bulk beverage vending machines, specifically relating to a liquid dispensing mechanism for a bulk wine vending machine. Background Technology

[0002] Most beverage vending machines currently on the market are designed for bottled drinks or alcoholic beverages. Their structural design and working principle are not suitable for selling bulk beverages. A few vending machines that are suitable for selling bulk beverages, such as the bulk beverage vending machine described in patent "CN104821045A", have their storage unit, metering unit, and dispensing unit arranged in an upper and lower position. The entire device is a small, single-item tabletop machine, which is not suitable for outdoor unmanned vending machines. Another patent, "CN206672244U", describes a bulk wine vending machine. Its main technical core lies in the control design of the dispensing end. The entire device needs to be installed in conjunction with the dispensing end of the storage unit, which is also not suitable for use in outdoor unmanned bulk wine vending machines.

[0003] Therefore, we propose a liquid dispensing mechanism suitable for outdoor bulk wine vending machines. Utility Model Content

[0004] The purpose of this invention is to provide a liquid dispensing mechanism for a bulk wine vending machine to solve the aforementioned problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liquid dispensing mechanism for a bulk wine vending machine includes a fixed frame. The fixed frame is designed with several fixed positions for fixing the containers used to store the liquid in the liquid dispensing mechanism, according to the internal space layout of the outdoor unmanned vending machine. Each fixed position in the fixed frame is equipped with a set of liquid dispensing mechanisms. Each set of liquid dispensing mechanisms mainly consists of a storage tank, an inlet / outlet control unit, and a dispensing component.

[0007] Furthermore, the liquid inlet / outlet control unit is installed on the cover of the storage tank, and the liquid inlet / outlet control unit includes an electromagnetic valve, a dual float level sensor, a liquid replenishment straight pipe, a suction pump, a built-in suction straight pipe, and a control module. The control module adopts a programmable PLC controller.

[0008] The built-in suction straight tube is connected to the suction port of the suction pump via a connecting pipe, and a solenoid valve B is installed in the middle section of the connecting pipe. The solenoid valve B effectively prevents backflow of the liquid in the infusion tube when the pump stops running, and also closes the built-in suction straight tube during replenishment operations. The bottom ends of both the replenishment straight tube and the built-in suction straight tube extend into the bottom of the storage tank, and the top end of the replenishment straight tube is connected to a replenishment tube for connecting to the replenishment port on the vending machine. The fact that the bottom end of the replenishment straight tube extends to the bottom of the storage tube allows the liquid level to rise steadily, improving the sensitivity of the liquid level sensor. It should be further noted that the bottom end of the replenishment straight tube can also be set near the opening or in the middle of the storage tank, depending on the requirements.

[0009] Furthermore, the solenoid valve is installed on the lid of the storage tank and connects the inside and outside of the tank. The main function of the solenoid valve is to balance the air pressure inside and outside the storage tank. When replenishing or transporting alcohol, the solenoid valve opens, allowing air inside the tank to be discharged or outside air to enter the tank, ensuring smooth replenishment and dispensing of alcohol.

[0010] Furthermore, the liquid outlet assembly is connected to the liquid inlet / outlet control unit via a delivery pipe. The liquid output from the liquid inlet / outlet control unit flows into the liquid outlet assembly through the delivery pipe. The liquid outlet assembly includes a liquid outlet pipe, on which a flow meter and a solenoid valve A are installed. The tail end of the liquid outlet pipe is connected to the output port of a suction pump. The solenoid valve A, in conjunction with the flow meter, enables precise filling of the liquid.

[0011] Furthermore, to prevent the suction pump from continuing to operate after solenoid valve A is closed, which could lead to increased pressure in the infusion tube and cause the end connection of the infusion tube to detach, a dedicated high-pressure switch for water circuit connection is installed at the end of the infusion tube near the suction pump. When solenoid valve A is closed, the suction pump continues to pump liquid into the infusion tube, causing the pressure inside the infusion tube to increase. At this time, the high-pressure switch detects the pressure change and sends a signal to the control module, which then controls the suction pump to stop running and simultaneously closes solenoid valve B.

[0012] Furthermore, to facilitate independent control of each group of liquid dispensing mechanisms, the solenoid valve A, solenoid valve B, solenoid air valve, high-pressure switch, suction pump, dual float level sensor, and flow meter on each group of liquid dispensing mechanisms are all electrically connected to the control module.

[0013] Furthermore, the control module in each liquid dispensing mechanism is electrically connected to the vending machine's POS system. Consumers can select the corresponding beverage category through the POS system on the vending machine. Based on the payment information received by the POS system, a signal is sent to the control module, which then controls the operation of solenoid valve A, solenoid valve B, suction pump, and solenoid valve. Meanwhile, the flow meter monitors the liquid output in real time.

[0014] Furthermore, since the alcohol in baijiu is volatile, in order to avoid changes in taste and improve safety during storage, the storage tank needs to adopt a heat insulation design. Specifically, the tank body includes an outer tank body and an inner tank body, with a heat insulation layer filling the space between the inner and outer tank bodies. The lid of the storage tank is detachably connected to the tank body via a quick-locking mechanism, and a sealing gasket is provided between the tank body and the lid.

[0015] Beneficial effects:

[0016] The wine dispensing mechanism proposed in this utility model is suitable for use in outdoor unmanned vending machines. It adopts an independent storage container, and each storage container is equipped with an inlet / outlet control unit that is bound to the cash register system of the vending machine. By combining the inlet / outlet control unit with the storage container, the main structure of the wine dispensing mechanism can be centralized, making the installation of the wine dispensing mechanism more convenient. Moreover, by installing multiple wine dispensing mechanisms in the vending machine, a diversified bulk wine sales mechanism can be formed. The entire wine dispensing mechanism has a simple structure, and its independent control design facilitates later maintenance, resulting in lower manufacturing and maintenance costs.

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0024] Example:

[0025] like Figures 1-5 As shown, this embodiment provides a liquid dispensing mechanism for a bulk wine vending machine, including a fixed frame 2. The fixed frame 2 is designed with several fixed positions for fixing the liquid containers used to store the liquid in the liquid dispensing mechanism, according to the internal space layout of the outdoor unmanned vending machine. Each of the fixed positions in the fixed frame 2 is equipped with a set of liquid dispensing mechanisms. Each set of liquid dispensing mechanisms mainly consists of a storage tank 1, an inlet / outlet control unit 3, and a dispensing component.

[0026] like Figure 3 , Figure 5 As shown, the liquid inlet / outlet control unit 3 is installed on the cover 102 of the storage tank 1, and the liquid inlet / outlet control unit 3 includes a solenoid valve 301, a dual float level sensor 302, a liquid replenishment straight pipe 303, a suction pump 304, a built-in suction straight pipe 309, and a control module 308. The control module 308 adopts a programmable PLC controller.

[0027] The built-in suction straight tube 309 is connected to the suction port of the suction pump 304 via a connecting pipe 306, and a solenoid valve B307 is installed in the middle section of the connecting pipe 306. The solenoid valve B307 effectively prevents the liquid in the infusion tube 4 from flowing back when the pump stops running. On the other hand, it can also close the built-in suction straight tube 309 during replenishment operations. The bottom ends of both the replenishment straight tube 303 and the built-in suction straight tube 309 extend into the bottom of the storage tank 1, and the top end of the replenishment straight tube 303 is connected to a replenishment tube 8 for connecting to the replenishment port on the vending machine. The bottom end of the replenishment straight tube 303 extends to the bottom of the storage tube, which can make the liquid level rise steadily and improve the sensitivity of the liquid level sensor. It should be further noted that the bottom end of the replenishment straight tube 303 can also be set near the opening or in the middle of the storage tank 1 as needed.

[0028] The electromagnetic valve 301 is installed on the cover 102 of the storage tank 1 and connects the inside and outside of the tank. The main function of the electromagnetic valve 301 is to balance the air pressure inside and outside the storage tank 1. When the wine is replenished or transported, the electromagnetic valve 301 is opened, which allows the air inside the tank to be discharged or the outside air to enter the tank, ensuring that the replenishment and dispensing of the wine are carried out smoothly.

[0029] like Figures 1-2 As shown, the liquid outlet assembly and the liquid inlet / outlet control unit 3 are connected by a liquid delivery pipe 4. The liquid output from the liquid inlet / outlet control unit 3 flows into the liquid outlet assembly through the liquid delivery pipe 4. The liquid outlet assembly includes a liquid outlet pipe 6, on which a flow meter 5 and a solenoid valve A7 are installed. The tail end of the liquid outlet pipe 6 is connected to the output port of the suction pump 304. The solenoid valve A7, in conjunction with the flow meter 5, enables precise filling of the liquid.

[0030] To prevent the suction pump 304 from continuing to operate after the solenoid valve A7 is closed, which could lead to an increase in pressure inside the infusion tube 4 and cause the end connection of the infusion tube 4 to detach, a dedicated high-pressure switch 305 for water circuit connection is installed at the end of the infusion tube 4 near the suction pump 304. When the solenoid valve A7 is closed, the suction pump 304 continues to pump liquid into the infusion tube 4, causing the pressure inside the infusion tube 4 to increase. At this time, the high-pressure switch 305 detects the pressure change and sends a signal to the control module 308, which then controls the suction pump 304 to stop running and simultaneously closes the solenoid valve B307.

[0031] To facilitate independent control of each group of liquid dispensing and filling mechanisms, the solenoid valves A7, B307, 301, 305, 304, 302, and 5 on each group of liquid dispensing and filling mechanisms are all electrically connected to the control module 308.

[0032] Furthermore, the control module 308 in each liquid dispensing mechanism is electrically connected to the vending machine's POS system. Consumers can select the corresponding beverage category through the POS system on the vending machine. Based on the payment information received by the POS system, a signal is sent to the control module 308, which then controls the operation of solenoid valve A7, solenoid valve B307, suction pump 304, and solenoid valve 301. Meanwhile, the flow meter 5 monitors the liquid output in real time.

[0033] like Figure 4 As shown, since the alcohol in baijiu is volatile, in order to avoid changes in taste and improve safety during storage, the storage tank 1 needs to adopt a heat insulation design. The tank body 101 of the storage tank 1 includes an outer tank body 111 and an inner tank body 112. A heat insulation layer 113 is filled between the inner tank body 112 and the outer tank body 111. The cap 102 of the storage tank 1 is detachably connected to the tank body 101 by a quick-locking fastener, and a sealing gasket 103 is provided between the tank body 101 and the cap 102.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
