Description

Technical Field

[0001] This invention relates to the field of cold drink machine technology, specifically to a beverage container assembly and a cold drink machine. Background Technology

[0002] Currently, commercial beverage machines, milk tea machines, and other similar equipment on the market generally use a peristaltic pump combined with multiple flexible tubes in their dispensing systems. This system delivers liquid by squeezing the tubes through the pump head and roughly estimates the dispensing volume by controlling the pump's operating time. This technology has several inherent drawbacks: First, beverage residue easily remains inside the complex piping system, making it extremely difficult to clean thoroughly. Over time, this inevitably becomes a breeding ground for bacteria, posing a serious food safety hazard. Second, the peristaltic pump tubing is a consumable part that requires frequent replacement, increasing maintenance costs and workload. Third, relying on time to control dispensing accuracy is low because the pump's output efficiency fluctuates with tubing wear, changes in back pressure, and differences in liquid viscosity, resulting in inconsistent actual beverage portions per cup, affecting product quality and commercial cost control.

[0003] Furthermore, most existing equipment uses a single refrigeration system for multiple containers, making it impossible to set independent temperatures for each container and thus failing to meet the varying storage temperature requirements of different raw materials. Additionally, many devices lack effective stirring functions, making it difficult to ensure consistent beverage concentration for easily sedimented powdered or fruit / pulp ingredients, severely impacting taste.

[0004] Therefore, there is an urgent need for a new type of cold drink machine that is easy to clean and maintain, can independently control temperature, and has a stirring function, in order to overcome the shortcomings of existing technologies. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a beverage container assembly and a beverage machine. Through the ingenious cooperation of a lever-type push rod and a counterweight valve body, the dispensing valve achieves purely mechanical opening and closing. This replaces the traditional pump system, completely avoiding the problems of beverage residue and pipeline cleaning. Simultaneously, multiple containers can be independently temperature-controlled and have a stirring function.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A beverage dispenser assembly includes a dispenser, an evaporator, an impeller, a pump body, a pump body retainer, and a dispensing system. The bottom of the material hopper is provided with an outlet; The evaporator is installed at the bottom of the material tank; The pump body is mounted on top of the evaporator via a pump body fixing clip; The impeller is located inside the pump body and is magnetic; The discharge system includes: a lever-type push rod and a counterweight valve body; The lever-type push rod includes a central pivot, a lower drive section, and an upper actuator section; the central pivot is rotatably connected to a mounting component; the lower drive section receives driving force; and the upper actuator section has an engagement opening. The counterweight valve body comprises, from top to bottom, a sealing end and a valve stem portion; the cross-sectional area of ​​the sealing end is larger than that of the material barrel outlet, and the cross-sectional area of ​​the valve stem portion is smaller than that of the material barrel outlet; the valve stem portion is provided with a radial flange; the valve stem portion has a hollow flow channel running from top to bottom, with its bottom end forming a water outlet; the side wall of the valve stem portion is provided with a guide hole communicating with the hollow flow channel; the engaging opening is sleeved on the valve stem portion and axially limited below the radial flange; a sealing element is sleeved on the top of the valve stem portion, above the guide hole; The fitting relationship between the sealing end and the outlet of the material barrel is as follows: First position: The sealing end is pressed against the outlet of the material barrel, and the guide hole is located below the outlet of the material barrel. At this time, the sealing element is press-fitted with the inner wall or end face of the outlet of the material barrel to achieve a seal. Second position: The valve stem is raised, the guide hole rises into the inside of the material tank, the sealing end is separated from the outlet of the material tank, and the liquid flows out from the outlet through the guide hole and the hollow flow channel in sequence.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the sealing element is an O-ring made of food-grade silicone, and its inner diameter is interference-fitted with the outer diameter of the valve stem.

[0009] Furthermore, the outer diameter of the valve stem is clearance-fitted with the outlet of the material barrel.

[0010] The present invention also provides a cold drink machine, including the above-described material tank assembly, the cold drink machine further including a chassis, and the mounting component being a bracket mounting groove provided on the shell of the chassis.

[0011] Furthermore, the discharge system also includes a drive component, which is a push rod motor installed inside the housing. The output end of the push rod motor is connected to a push head, and the lower drive part contacts the front end of the push head. The push rod motor is equipped with a limit sensor.

[0012] Furthermore, a waterproof sleeve is fitted over the outside of the ejector head. The outer ring of the waterproof sleeve has an annular groove, and the chassis has a matching mounting hole. The waterproof sleeve is fixed in the mounting hole by snapping into the groove.

[0013] Furthermore, the beverage cooler also includes a water receiving tray located below the water outlet, and a weighing sensor is installed inside the water receiving tray; an electronic control board is installed on the chassis, wherein the electronic control board is electrically connected to the weighing sensor, the push rod motor and the limit sensor respectively.

[0014] Furthermore, it also includes a refrigeration system for cooling the hopper, the refrigeration system comprising a compressor, a condenser, and an evaporator connected by piping.

[0015] Furthermore, the number of refrigerant tanks is multiple, and the refrigeration system also includes multiple solenoid valves. The number of solenoid valves corresponds to the number of refrigerant tanks. Each solenoid valve is connected in series in the inlet pipe of the evaporator of the corresponding refrigerant tank, and is used to independently control the flow of refrigerant into each evaporator.

[0016] Furthermore, it also includes a stirring system, which includes a lower magnet motor and the impeller. The lower magnet motor is installed below the evaporator, and its output shaft is equipped with a lower magnet. The lower magnet is magnetically coupled to the impeller. When the lower magnet motor is working, it drives the impeller to rotate through magnetic force to stir the beverage in the material tank.

[0017] The beneficial effects of this invention are: 1. This embodiment replaces the complex piping and pump system of traditional beverage machines by using a drive unit, lever-type push rod, and counterweight valve body. This structure has a low failure rate, direct feedback, and rapid response. The unique design of the counterweight valve body utilizes its own gravity to achieve sealing, and by switching between two positions, it achieves reliable sealing and a smooth dispensing process.

[0018] 2. This embodiment employs non-contact magnetic stirring and a modular, detachable structure. The stirring system uses an external motor to drive the internal impeller, completely eliminating the mechanical drive shaft passing through the material tank and fundamentally eliminating the risk of shaft seal leakage and cleaning dead zones. Simultaneously, the evaporator achieves quick connection and separation from the bottom of the material tank via external clips. The counterweight valve body is easy to disassemble and clean. Combined with the easily removable counterweight valve body and impeller, the material tank can be quickly and completely separated from all components. The separated material tank becomes a smooth, uncomplicated, independent container, allowing users to directly and thoroughly rinse and scrub it, greatly improving cleaning efficiency.

[0019] 3. This embodiment adopts a multi-path independently controlled refrigeration cycle. By flexibly distributing refrigerant through the on / off state of solenoid valves, it achieves independent and precise temperature control for multiple material tanks, which is energy-saving and can meet the storage needs of different beverages.

[0020] 4. In this embodiment, a non-contact transmission with magnetic coupling is used, which achieves effective stirring while ensuring the integrity and sealing of the hopper and eliminating the risk of transmission shaft leakage. Attached Figure Description

[0026] Example This embodiment provides a beverage container assembly for a cold drink machine, such as... Figure 1-5 As shown, it includes a material hopper 6, an evaporator 71, an impeller 83, a pump body 82, a pump body fixing clip 81, and a discharge system; The bottom of the material hopper 6 is provided with an outlet; The evaporator 71 is installed at the bottom of the material tank 6; The pump body 82 is mounted above the evaporator 71 via a pump body 82 fixing clip 81; The impeller 83 is disposed inside the pump body 82 and is magnetic; The discharge system includes: a lever-type push rod 2 and a counterweight valve body 3; The lever-type push rod 2 includes a central pivot 21, a lower drive part 22, and an upper execution part 23; the central pivot 21 is rotatably connected to a mounting component; the lower drive part 22 is used to receive driving force; the upper execution part 23 is provided with an engagement opening 231; The counterweight valve body 3 includes, from top to bottom, a sealing end 31 and a valve stem portion 32; the cross-sectional area of ​​the sealing end 31 is larger than that of the material barrel 6 outlet, and the cross-sectional area of ​​the valve stem portion 32 is smaller than that of the material barrel 6 outlet; the valve stem portion 32 is provided with a radial flange; the valve stem portion 32 has a hollow flow channel 322 that runs from top to bottom, with its bottom end forming a water outlet; the side wall of the valve stem portion 32 is provided with a guide hole 321 that communicates with the hollow flow channel 322; the engaging opening 231 is sleeved on the valve stem portion 32 and axially limited below the radial flange; a sealing element 33 is sleeved on the top of the valve stem portion 32, above the guide hole 321; The fitting relationship between the sealing end 31 and the outlet of the material barrel 6 is as follows: First position: The sealing end 31 is pressed against the outlet of the material barrel 6, and the guide hole 321 is located below the outlet of the material barrel 6. At this time, the sealing element 33 is press-fitted with the inner wall or end face of the outlet of the material barrel 6 to achieve sealing. Second position: Valve stem 32 is raised, guide hole 321 rises into the inside of material tank 6, sealing end 31 is separated from the outlet of material tank 6, and liquid flows out from the outlet through guide hole 321 and hollow flow channel 322 in sequence.

[0027] In this embodiment, the material tank 6 is made of food-grade plastic, with a circular outlet and a circular mounting port at the center of its bottom. The diameter of the circular mounting port is larger than that of the circular outlet. The evaporator 71 is shaped to match the circular mounting port, and a sealing ring 61 is fitted around its outer edge. The evaporator 71 is inserted into the circular mounting port, and a sealed connection with the material tank 6 is achieved using the sealing ring 61. An upwardly extending mounting shaft is fixedly provided at the center of the evaporator 71.

[0028] The impeller 83 has a central shaft hole, through which it is fitted onto the mounting shaft of the evaporator 71 via a mandrel 84, allowing it to rotate freely. The pump body 82, acting as a power-free housing, is secured to the upper center of the evaporator 71 by a pump body 82 fixing clip 81, housing the impeller 83 within this housing. A permanent magnet (upper magnet) is embedded in the center of the impeller 83.

[0029] The disassembly and cleaning process in this embodiment is as follows: When cleaning is required, first lift the counterweight valve body 3 upwards to separate it from the engaging opening 231 of the lever-type push rod 2, and remove the valve body from the circular outlet. Then, loosen the pump body 82 fixing clip 81 and remove the pump body 82 cavity shell from above the evaporator 71. Subsequently, push the evaporator 71 outwards from the circular mounting port at the bottom of the material tank 6, separating the evaporator 71 assembly (along with its central mounting shaft) from the material tank 6. Finally, the impeller 83 can be removed directly upwards from the material tank 6. At this point, the inside of the material tank 6 is completely separated from all external functional components, becoming an independent container with a smooth interior without dead corners, enabling rapid and thorough rinsing and scrubbing, greatly improving the convenience and thoroughness of cleaning.

[0030] It should be noted that the lever-type push rod 2 is specifically embodied as an inverted L-shaped metal plate. The central pivot 21 of this metal plate serves as the rotation center, and its two ends extend axially outward with protrusions 211. A groove matching the shape is machined at the corresponding position on the inner wall of the cold drink machine casing 4. This groove serves as the mounting component, and the central pivot 21 is directly placed in it through the protrusions 211 and can rotate relative to it. The lower long side of the metal plate serves as the lower driving part 22, which contacts the plane of the push head 12 of the driving component; its upper short side is provided with an O-hole, which is the engaging opening 231. The counterweight valve body 3 is an integrally formed cylindrical structure that is wider at the top and narrower at the bottom. The wider cylinder at the top serves as the sealing end 31, and the narrower cylinder at the bottom serves as the valve stem portion 32. The valve stem portion 32 has a hollow flow channel 322 that runs from top to bottom, and the bottom end of the hollow flow channel 322 forms the water outlet. At least one guide hole 321 communicating with the hollow flow channel 322 is provided on the side wall of the valve stem portion 32. A radial flange is also machined on the outer wall of the valve stem portion 32. The O-ring is fitted onto the valve stem portion 32 and axially limited below the radial flange. In the initial first position, the entire counterweight valve body 3 falls under its own weight, causing its sealing end 31 to press against the outlet of the material tank 6. At this time, the guide hole 321 on the valve stem 32 is located below the outlet of the material tank 6, and the sealing element 33 sleeved on the top of the valve stem 32 forms an interference fit with the inner wall of the outlet of the material tank 6 to achieve a seal. When the driving component pushes the lower end of the lever, the lever rotates around the central protrusion 211, and the O-hole at its upper end lifts upward, causing the entire counterweight valve body 3 to move upward to the second position: the sealing end 31 disengages from the outlet of the material tank 6, and the guide hole 321 rises to below the liquid level inside the material tank 6. Under the action of gravity, the liquid inside the material tank 6 immediately flows into the hollow flow channel 322 through the guide hole 321 and finally flows out smoothly from the outlet at the bottom.

[0031] In a preferred embodiment, such as Figure 3 As shown, the sealing element 33 is an O-ring made of food-grade silicone, and its inner diameter is interference-fitted with the outer diameter of the valve stem portion 32.

[0032] It should be noted that this embodiment uses food-grade silicone to ensure food safety in the parts that come into contact with beverages. The interference fit of the O-ring provides reliable and durable sealing performance, preventing liquid from leaking from the outer wall of the valve stem 32.

[0033] In a preferred embodiment, the outer diameter of the valve stem portion 32 is clearance-fitted with the outlet of the material barrel 6.

[0034] It should be noted that the outer diameter of the valve stem portion 32 in this embodiment is designed to form an assembly gap with the inner diameter of the outlet of the material tank 6, so as to ensure that the counterweight valve body 3 can move freely and effectively guide the flow. This gap ensures that most of the liquid will flow down through the hollow flow channel 322 of the valve stem portion 32, and only a very small portion will flow down through the gap.

[0035] The present invention also provides a cold drink machine, such as Figure 2-3 As shown, the beverage machine includes the aforementioned material tank assembly and also includes a housing 4. The mounting component is a bracket mounting groove 42 provided on the housing of the housing 4.

[0036] In this embodiment, a mounting groove 42 is machined on the inner wall of the cold drink machine casing 4 at the position corresponding to the central pivot 21. The mounting groove 42 is a groove, which serves as the mounting component and is rotatably connected to the central pivot 21.

[0037] In a preferred embodiment, such as Figure 1 and Figure 6 As shown, the discharge system also includes a drive component, which is a push rod motor 1 installed inside the housing 4. The output end of the push rod motor 1 is connected to a push head 12, and the lower drive part 22 is in contact with the front end of the push head 12. A limit sensor 11 is provided on the push rod motor 1.

[0038] Specifically, a waterproof sleeve 13 is fitted over the outside of the ejector head 12. The waterproof sleeve 13 has an annular groove on its outer ring. The housing 4 has a matching mounting hole 41. The waterproof sleeve 13 is fixed in the mounting hole 41 by the groove.

[0039] In this embodiment, the push rod motor 1 is fixed to the housing 4 by a mounting plate, and its output end is connected to a push head 12 via a threaded connector. The lower end of the lever-type push rod 2 is in contact with the front hemispherical surface of the push head 12. A waterproof rubber sleeve 13 is also included, which is fitted onto the push head 12, and has an annular groove on its outer circumference. A circular hole 41 is opened on the side wall of the housing 4 as a mounting hole, and the inner edge of the circular hole fits into the groove of the waterproof sleeve 13, thereby achieving a dynamic seal.

[0040] It solves the sealing problem between the output shaft of the push rod motor 1 and the mounting hole 41 of the housing 4. The design of the waterproof sleeve 13 and its annular groove effectively prevents condensate inside the housing 4 or a small amount of liquid flowing out from the gap between the valve stem part 32 and the outlet of the material bucket 6 from seeping into the housing 4, protecting the internal electrical components and improving the reliability and service life of the whole machine.

[0041] It should be noted that the limit sensor 11 provides the electrical control system with physical position feedback of the motor. This sensor can be used to calibrate the initial (origin) and end positions of the push rod motor 1, ensuring that the starting point of each push rod action is consistent. This provides key position information for achieving repeatable and accurate control of the output, and also prevents the motor from overshooting and damaging the mechanism.

[0042] In a preferred embodiment, such as Figure 1-3 As shown, the cold drink machine also includes a water receiving tray 5, which is located below the water outlet. A weighing sensor 51 is installed inside the water receiving tray 5. An electronic control board is installed on the chassis 4, wherein the electronic control board is electrically connected to the weighing sensor 51, the push rod motor 1, and the limit sensor 11, respectively.

[0043] In this embodiment, an electronic control board is installed inside the chassis 4. It is connected to the signal output terminal of the weighing sensor 51, the power input terminal of the push rod motor 1, and the signal terminal of the limit sensor 11 via wiring harnesses. As the physical carrier of the electronic control logic, the electronic control board receives the weight signal from the weighing sensor 51 and the position signal from the limit sensor 11, processes and makes logical judgments, and outputs control commands to drive the push rod motor 1 to work, thereby realizing the automatic operation of the material discharge process.

[0044] In a preferred embodiment, a refrigeration system for cooling the hopper 6 is also included, such as... Figure 8 As shown, the refrigeration system includes a compressor 72, a condenser 73, and an evaporator 71 connected by pipes.

[0045] Specifically, there are multiple refrigerant tanks 6, and the refrigeration system also includes multiple solenoid valves 74. The number of solenoid valves 74 corresponds to the number of refrigerant tanks 6. Each solenoid valve 74 is connected in series in the inlet pipe of the evaporator 71 of the corresponding refrigerant tank 6, and is used to independently control the flow of refrigerant into each evaporator 71.

[0046] In this embodiment, the compressor 72, condenser 73, and evaporator 71 are installed inside the casing 4, and the beverage cooler includes four material tanks 6. The refrigeration system accordingly includes four normally closed solenoid valves 74. Each solenoid valve 74 is connected in series in a copper pipe leading to the corresponding material tank 6 and evaporator 71. The coil of the solenoid valve 74 is connected to the electronic control board through a wiring harness, and its opening and closing are independently controlled by the electronic control board.

[0047] In a preferred embodiment, a stirring system is also included, such as Figure 5 As shown, the stirring system includes a lower magnet 86, a motor 85, and an impeller 83. The lower magnet 86 and motor 85 are installed below the evaporator 71, and the lower magnet 86 is provided on its output shaft. The lower magnet 86 is magnetically coupled to the impeller 83. When the lower magnet 86 and motor 85 are working, the impeller 83 is driven to rotate by magnetic force to stir the beverage in the material tank 6.

[0048] In this embodiment, the motor is mounted on the casing 4 below the evaporator 71 via a bracket. Its output shaft points vertically upwards, and a permanent magnet is fixed to the end of the output shaft, serving as the lower magnet 86. A permanent magnet is embedded in the center of the impeller 83, serving as the upper magnet. The lower magnet 86 corresponds vertically to the upper magnet in the center of the impeller 83 inside the material tank 6, forming a magnetic coupling pair. When the control board starts the motor 85 of the lower magnet 86, the lower magnet 86 rotates, driving the impeller 83 inside the material tank 6 to rotate synchronously via magnetic force, thereby stirring the beverage.

[0049] This embodiment solves the problem of solid component precipitation in beverages by using a stirring system, maintaining a uniform beverage concentration and taste. A magnetic stirring method, driven by a lower magnet 86 and a motor 85, magnetically coupled to an impeller 83, achieves completely non-contact power transmission. The impeller 83 rotates and stirs within the sealed container 6, eliminating the need for a drive shaft to be installed through a hole in the container 6. This completely eliminates potential leakage and unsanitary areas at the shaft seal, resulting in better sealing of the container 6 and easier cleaning.

[0050] In this embodiment, the output port of the electronic control board is connected to the drive circuit (usually a motor driver or relay module) of the lower magnet 86 motor 85 via a wire. The electronic control board provides power and sends control signals to the driver, which then supplies appropriate current and voltage to the lower magnet 86 motor 85. The electronic control board directly controls the start and stop of the stirring system. It drives the motor to rotate by sending command signals to the driver of the lower magnet 86 motor 85, which in turn drives the impeller 83 in the material tank 6 through magnetic coupling. This control can be based on manual operation by the user, a preset timing program, or automatic logic linked with other functions (such as discharging). Its core purpose is to ensure uniform mixing of the beverage and prevent sedimentation.

[0051] In a preferred embodiment, such as Figure 2 and Figure 7 As shown, the outer surface of the chassis 4 is provided with a unique QR code 43 that identifies the machine; The electronic control board is also equipped with an Internet of Things (IoT) communication module for establishing a communication connection with the server; The server is configured to: scan the QR code 43, provide a control interface to the user terminal; receive control commands from the user terminal through the control interface, and forward the commands to the electronic control board; The electronic control board is further configured to control the push rod motor 1 to work according to the received control command.

[0052] In this embodiment, a QR code 43 is affixed to the front of the chassis 4. A Wi-Fi IoT communication module is integrated into the control board. After the user scans the QR code 43 with their mobile phone, the phone is redirected to a control page provided by a cloud server. After the user selects the beverage and portion size, the control command is sent to the cloud server, which then forwards the command to the machine's control board. The control board parses the command and activates the corresponding push rod motor 1 to perform the dispensing operation. This adds IoT functionality to the beverage machine. Its technical advantage lies in achieving remote control and intelligent management. Each device is uniquely identified by the QR code 43, allowing users to scan the code with their mobile phones or other terminals to access the control interface from the server and remotely issue dispensing commands. The control board communicates with the server via the IoT module, receiving and executing commands. This meets the remote management needs of commercial equipment.

[0053] The overall working process of this invention is as follows: The entire operation of this beverage cooler begins with an IoT command from the user. The user scans the QR code 43 on the machine using a mobile device. After the server identifies the unique device, it pushes a control interface to the user. After the user selects the desired beverage and quantity on the interface and confirms, the control command is forwarded by the server to the electronic control board of that beverage.

[0054] After receiving the discharge command, the electronic control board starts the corresponding push rod motor 1. The output shaft of the push rod motor 1 extends and pushes the lower drive part 22 of the lever-type push rod 2. The lever-type push rod 2 rotates around its central pivot 21, and its upper actuator 23 is lifted upward accordingly. Since the engagement opening 231 of the actuator is fitted on the valve stem part 32 of the counterweight valve body 3 and is limited to below the radial flange, the upward movement of the lever overcomes the weight of the valve body and the liquid pressure, lifting the entire counterweight valve body 3 upward.

[0055] The counterweight valve body 3 moves upward, causing its top sealing end 31 to disengage from the outlet of the material tank 6, switching from the first position to the second position. Simultaneously, the guide hole 321 on the side wall of the valve stem 32 rises below the liquid level inside the material tank 6. Under the influence of gravity, the liquid inside the material tank 6 immediately flows through the guide hole 321 into the hollow flow channel 322 of the valve stem 32, and flows out from the outlet at the bottom of the hollow flow channel 322, falling into the water receiving tray 5 below.

[0056] The weighing sensor 51 at the bottom of the water receiving pan 5 monitors the weight change of the liquid in the water receiving pan 5 in real time and transmits the weight data to the electronic control board. The electronic control board compares the real-time weight with the target weight set by the user. When the real-time weight is close to the target weight, the electronic control board controls the push rod motor 1 to decelerate; when the real-time weight reaches the target weight, the electronic control board immediately cuts off the power to the push rod motor 1.

[0057] After the push rod motor 1 is de-energized, its output shaft retracts, the lever-type push rod 2 rotates in the opposite direction, and the counterweight valve body 3 descends under its own gravity. Its sealing end 31 then re-presses the outlet of the material container 6, returning to the first sealing position, thus ending the discharge process. Simultaneously, the control board feeds back the information of this completed discharge to the server via the IoT module, thereby completing a full automated discharge cycle. During the entire process, if stirring is required, the control board can control the lower magnet 86 motor 85 to operate, driving the impeller 83 to rotate and prevent beverage sedimentation.

[0058] In summary, this embodiment utilizes a lever mechanism to convert the linear thrust of the motor into a force that lifts the counterweight valve body 3, using gravity as the discharge power, and employs a weighing sensor 51 as a feedback element to form a closed-loop control system, thereby achieving control of the discharge amount.
