[0085] See Figures 1 to 21As shown, the present application discloses a liquid dispensing machine, which includes a cabinet 1, a heat preservation device, a refrigeration device, a material box device, a liquid dispensing head, and a liquid dispensing control system 10. The cabinet 1 is provided with a storage surface, the heat preservation device is provided on the storage surface of the cabinet 1, and the heat preservation device includes a plurality of first liquid storage containers 602, the first liquid storage containers 602 are used to store a first liquid material, and the first liquid material is a heat preservation material. The cabinet 1 is provided with a refrigeration chamber 401, the refrigeration device is provided in the refrigeration chamber 401 of the cabinet 1, and the refrigeration device includes a plurality of second liquid storage containers 601, the second liquid storage containers 601 are used to store a second liquid material, and the second liquid material is a refrigerated material. The cabinet 1 is provided with a batching cabinet 2000, and the material box device is provided in the batching cabinet 2000 of the cabinet 1, and the material box device includes a plurality of material boxes 2000a, and the material boxes 2000a are used to store at least one of solid materials, solid-liquid mixture materials, and concentrated slurry materials. Furthermore, the plurality of material boxes 2000a may include refrigerated material boxes for refrigerated storage and normal temperature material boxes for room temperature storage. In one embodiment, the 12 material boxes 2000a provided on the refrigerator countertop may be configured as refrigerated material boxes, and the 6 material boxes 2000a located above the refrigerated material boxes may be configured as normal temperature material boxes. Those skilled in the art may store different materials in refrigerated material boxes or normal temperature material boxes according to their storage requirements. The liquid dispensing head is provided in the cabinet 1 and is provided with at least one third liquid storage container 603, which is used to store syrup.

[0086] The liquid discharge control system 10 includes a control mainboard 300 and multiple groups of liquid discharge structures 100 arranged in parallel. The liquid discharge structures 100 include a power assembly 110 and a liquid discharge pipe 120. The power assembly 110 is connected to the liquid discharge pipe 120. Each first liquid storage container 602, each second liquid storage container 601, and each third liquid storage container 603 is connected to the liquid discharge head via a liquid discharge pipe 120. The control mainboard 300 is electrically connected to the power assemblies 110 of the multiple liquid discharge structures 100. Each power assembly 110 can be used to extract the first liquid material in the first liquid storage container 602, the first liquid material in the second liquid storage container 601, and the syrup in the third liquid storage container 603 through the corresponding liquid discharge pipe 120 under the control of the control mainboard 300 and deliver them to the liquid discharge head.

[0087] It can be seen from this that the above-mentioned control motherboard 300 can control the action of the power component 110 of any liquid outlet structure 100, so that different power components 110 can extract materials through the liquid outlet pipes 120 connected to them, including extracting the first liquid material in the first liquid storage container 602 through the liquid outlet pipes 120 connected to different first liquid storage containers 602, extracting the first liquid material in the second liquid storage container 601 through the liquid outlet pipes 120 connected to different second liquid storage containers 601, and extracting the syrup in the third liquid storage container 603 through the liquid outlet pipes 120 connected to different third liquid storage containers 603.

[0088] Among them, the control motherboard 300 can be connected to a data storage device, which is used to store production recipes of several types of beverages. Based on different production recipes, various types of milk tea beverages can be made. For example, the production recipe includes the type and content of the first liquid material of different types of beverages, the type and content of the second liquid material, and the type and content of syrup, etc. Based on the types of various liquid materials and syrups, the type of the first liquid material can include several types of hot tea, the type of the second liquid material can include several types of milk, coconut milk, coconut water, etc., and the syrup can include various types of syrups such as sucrose syrup, fructose syrup and honey syrup.

[0089] After the recipes for several types of beverages are stored in the data storage, when the liquid dispensing machine receives an order for a corresponding type of beverage, the control motherboard 300 can directly retrieve the recipe data for the corresponding type of beverage from the data storage and then control the power components 110 of the liquid dispensing structures 100 to perform corresponding actions based on the recipe data. For example, the control motherboard 300 can control the power components 110 on one or more liquid outlet pipes 120 connected to the first liquid storage container 602 to extract one or more first liquid materials from the one or more first liquid storage containers 602 through the one or more liquid outlet pipes 120 connected to the first liquid storage container 602 and control the extraction content of the one or more first liquid materials. Similarly, the control motherboard 300 can control the power components 110 on one or more liquid outlet pipes 120 connected to the second liquid storage container 601 to extract one or more second liquid materials from the one or more second liquid storage containers 601 through the one or more liquid outlet pipes 120 connected to the second liquid storage container 601 and control the extraction content of the one or more second liquid materials. Similarly, the power assembly 110 on one or more liquid outlet pipes 120 connected to the third liquid storage container 603 is controlled to extract one or more syrups in the one or more third liquid storage containers 603 through one or more liquid outlet pipes 120 connected to the third liquid storage container 603, and the extraction content of the one or more syrups is controlled.

[0090] Once the types and contents of the first liquid material, second liquid material, and syrup are determined, they can be delivered simultaneously or in batches along the corresponding liquid outlet pipes 120 to the liquid outlet head, where they are then output and mixed into the disposable beverage cup to create the desired beverage. At this point, the store clerk can manually select one or more solid materials, solid-liquid mixtures, or concentrated slurries from one or more material containers 2000a and place them in the disposable beverage cup to complete the beverage preparation. These solid materials include various dried fruits, coconut flakes, fruit cuts, and edible pearls, which are solid ingredients in the beverage.

[0091] Therefore, the above-mentioned liquid dispenser can automatically and quickly prepare liquid materials and syrups for various beverages, typically completing such preparation in just a few seconds. Store employees no longer need to memorize numerous recipes for different beverages. Instead, they only need to quickly prepare the liquid materials and syrups for each beverage and then manually select one or more solid materials, solid-liquid mixtures, or concentrated slurries from one or more material containers 2000a. This significantly reduces the operational requirements for store employees, eliminates the need for extensive staff training, and significantly reduces training costs. Beverage orders can be automatically and quickly fulfilled, significantly improving order efficiency and accuracy.

[0092] In the above embodiment, the liquid outlet structure 100 is a component for extracting liquid material. The liquid outlet structure 100 has an inlet end and an outlet end. The inlet end of the liquid outlet structure 100 is the end for liquid material to enter, and the outlet end of the liquid outlet structure 100 is the port for liquid material to be discharged. The inlet end of the liquid outlet structure 100 is connected to the corresponding liquid storage container (the liquid storage container herein refers to the first liquid storage container 602, the second liquid storage container 601, and the third liquid storage container 603 described above), and the outlet end of the liquid outlet structure 100 is connected to the liquid outlet port 501.

[0093] The liquid dispensing machine can control the liquid dispensing structure 100 to extract liquid material from the liquid storage container and deliver the liquid material to a container, such as a disposable drinking cup, through the liquid dispensing structure 100 through the liquid dispensing port 501, thereby producing a drink. Furthermore, the liquid dispensing structure 100 is disposed within the cabinet 1, and the various pipes of the liquid dispensing structure 100 are concealed by the cabinet 1, preventing them from being exposed and ensuring safe liquid material delivery.

[0094] There are multiple groups of liquid outlet structures 100, each of which is arranged in parallel within the ingredient cabinet 2000 of the cabinet 1. The inlet end of each group of liquid outlet structures 100 is connected to a respective liquid storage container, and the outlet end of each group of liquid outlet structures 100 is connected to the liquid outlet port 501. In this way, each liquid storage container can deliver liquid material through the corresponding liquid outlet structure 100, preventing the liquid materials from mixing during delivery and ensuring the taste of the beverage.

[0095] Specifically, each liquid outlet structure 100 includes a power assembly 110 and a liquid outlet pipe 120. The power assembly 110 is disposed on the liquid outlet pipe 120, one end of which is connected to each liquid storage container in the liquid outlet machine, and the other end of each liquid outlet structure 100 is connected to the liquid outlet port 501 of the liquid outlet machine.

[0096] The liquid outlet pipe 120 is a pipeline for transporting liquid materials. The liquid outlet pipe 120 has an inlet end and an outlet end. The inlet end of the liquid outlet pipe 120 is connected to the liquid storage container, and the outlet end of the liquid outlet pipe 120 is connected to the liquid outlet port 501. The power assembly 110 is the power source of the liquid outlet structure 100 and is disposed in the middle area of ​​the liquid outlet pipe 120.

[0097] When making drinks, the liquid dispenser controls the corresponding power component 110 to work. At this time, the power component 110 can extract the liquid material in the corresponding liquid storage container into the liquid outlet pipe 120, and transport it to the liquid outlet port 501 through the liquid outlet pipe 120, and then output the liquid material through the liquid outlet port 501.

[0098] The control motherboard 300 is disposed on the back of the cabinet 1 and is electrically connected to the power assembly 110 in each group of liquid discharge structures 100. The control motherboard 300 automatically controls each power assembly 110, thereby enabling automatic liquid discharge control of the liquid discharge machine. In other words, the control motherboard 300 serves as the main control board of the liquid discharge machine, enabling intelligent liquid discharge control of the liquid discharge machine. Optionally, the control motherboard 300 is a PCB.

[0099] When the liquid dispenser receives the order information, it sends a control signal based on the order information to the control board 300. After receiving the control signal, the control board 300 analyzes the order information and generates liquid discharge information for the liquid dispenser. The control board 300 then sends the liquid discharge information to the corresponding power assembly 110, enabling the power assembly 110 to extract the liquid material from the corresponding storage container through the liquid discharge pipe 120.

[0100] Furthermore, after receiving the liquid discharge information, the power assembly 110 discharges liquid according to the time specified in the liquid discharge information, such as the time after which the power assembly 110 is activated to pump liquid. In this way, each power assembly 110 can operate according to the control timing indicated by the liquid discharge information transmitted by the control mainboard 300, thereby achieving the sequential preparation of multiple cups of beverages and improving the operating efficiency of the liquid dispenser.

[0101] In the liquid discharge control system 10 of the above-described embodiment, each group of liquid discharge structures 100 is independently provided. The power assembly 110 in each group of liquid discharge structures 100 is provided on the liquid discharge pipe 120. The power assembly 110 can extract the liquid material from the corresponding liquid storage container through the liquid discharge pipe 120 and output it through the liquid discharge port 501. The control mainboard 300 is electrically connected to the power assembly 110 of each liquid discharge structure 100. The control mainboard 300 can trigger a liquid discharge signal based on the order information of the liquid discharge machine and transmit the liquid discharge signal to the corresponding power assembly 110 to perform the corresponding liquid discharge operation. In this way, the coordination between the control mainboard 300 and each group of liquid discharge structures 100 can simplify the liquid discharge operation process of the liquid discharge machine, making it easier for the operator to operate.

[0102] There are ten groups of liquid outlet structures 100, and ten liquid storage containers, including six second liquid storage containers 601 and four first liquid storage containers 602. Six of the liquid outlet structures 100 are connected to the second liquid storage containers 601, and four of the liquid outlet structures 100 are connected to the first liquid storage containers 602. Of course, in other embodiments of the present application, the number of liquid outlet structures 100 can be other, and the number of second liquid storage containers 601 and first liquid storage containers 602 can also be adjusted.

[0103] It is worth noting that the principle of the liquid outlet structure 100 transporting the liquid material in the second liquid storage container 601 is essentially the same as the principle of transporting the liquid material in the first liquid storage container 602. In this application, only the liquid outlet structure 100 transporting the liquid material in the liquid storage container is used as an example for description. Furthermore, which liquid outlet structure 100 is connected to the second liquid storage container 601 and which liquid outlet structure 100 is connected to the first liquid storage container 602 will not be further explained.

[0104] In one embodiment, the surface of the storage surface has an inclination angle of 3°; and / or,

[0105] The storage surface is located at the top of the cabinet 1, the refrigeration chamber 401 is located at the bottom of the cabinet 1, and the ingredient cabinet 2000 is located between the storage surface and the refrigeration chamber 401; and / or,

[0106] The ingredient cabinet 2000 is provided with an assembly frame 1000, which has a storage space 1000a within it. The six material boxes 2000a placed within the storage space 1000a can now be configured as room-temperature material boxes. The material boxes 2000a include a main body 2100a and a retaining flange 2200a, which is connected to the upper edge of the main body 2100a. The main body 2100a is a rectangular box with a length L1 and a width L2, satisfying the relationship: L1>L2. The width of the storage space 100a is L3, satisfying the relationship: L1>L3≥L2.

[0107] The container 2000a can be configured in multiple configurations, each capable of containing different ingredients (e.g., pearls, fruit, etc.). A storage space 1000a is formed within the assembly frame 1000. The container 2000a includes a main body 2100a and a retaining flange 2200a connected to the upper edge of the main body 2100a.

[0108] During the process of assembling a single material box body 2000a on the assembly frame 1000, the material box body 2000a is placed into the placement space 1000a from the top of the assembly frame 1000. When the assembly of the material box body 2000a and the assembly frame 1000 is completed, the box body 2100a is passed through the placement space 1000a, and the limiting flange 2200a abuts against the upper surface of the assembly frame 1000 to limit the relative position of the material box body 2000a and the assembly frame 1000 in the thickness direction of the assembly frame 1000.

[0109] The box body 2100a has a material holding space formed therein for holding ingredients. A user places ingredients into the box body 2000a through an open port in the material holding space, and removes ingredients placed in the box body 2000a through the open port. It should be noted that the upper edge of the box body 2100a defines the open port of the material holding space.

[0110] Furthermore, the limiting flange 2200a is an integrally formed annular plate, extending along the upper edge of the box body 2100a so that when the material container 2000a is assembled on the assembly frame 1000, the limiting flange 2200a is adapted to abut against the assembly frame 1000 to limit the position. It should be noted that, in this application, the limiting flange 2200a is described as an integrally formed annular plate, but the application is not limited thereto. For example, the structure of the limiting flange 2200a can also be a long strip plate. A single material box body 2000a can have at least two limiting flanges 2200a with a long strip plate structure. In the width direction of the material box body 2000a, the two limiting flanges 2200a are respectively connected to the two sides of the box body 2100a, so that when the material box body 2000a is assembled on the assembly frame 1000, the limiting flanges 2200a are suitable for abutting against the assembly frame 1000 for limiting.

[0111] In some embodiments of the present application, the assembly frame 1000 may be a first assembly frame 1000 or a second assembly frame 1000 , wherein the first assembly frame 1000 has one placement space 1000 a formed therein, and the second assembly frame 1000 has two placement spaces 1000 a formed therein.

[0112] The first assembly frame 1000 has a rectangular structure and defines a placement space 1000a therein. Specifically, the first assembly frame 1000 is composed of two first longitudinal beams 1100a and two first transverse beams 1100b. The two first transverse beams 1100b are positioned opposite each other in the length direction of the first assembly frame 1000 (i.e., the X-direction shown in the figure), and the two first longitudinal beams 1100a are positioned opposite each other in the width direction of the first assembly frame 1000 (i.e., the Y-direction shown in the figure). This results in the rectangular structure of the first assembly frame 1000 and the placement space 1000a defined therein.

[0113] Second assembly frame 1000 includes a frame body 12100 and partitioning longitudinal beams 12200. Frame body 12100 has a rectangular structure. Partitioning longitudinal beams 12200 are fixed to frame body 12100 to define two placement spaces 1000a within frame body 12100. Specifically, frame body 12100 is composed of two second longitudinal beams 12100a and two second transverse beams 12100b. The two second transverse beams 12100b are positioned opposite each other in the length direction of second assembly frame 1000 (i.e., the X-direction shown in the figure). The two second longitudinal beams 12100a are positioned opposite each other in the width direction of second assembly frame 1000 (i.e., the Y-direction shown in the figure), resulting in a rectangular structure for second assembly frame 1000. In addition, the partition longitudinal beam 12200 is connected between the two second transverse beams 12100 b and is parallel to the two second longitudinal beams 12100 a , so that the partition longitudinal beam 12200 defines two placement spaces 1000 a in the frame body 12100 .

[0114] Therefore, the assembly frame 1000 (eg, the first assembly frame 1000 or the second assembly frame 1000 ) according to the present application has a simple structure, thereby avoiding the problem of sanitary blind spots, and facilitating the user to clean the assembly frame 1000 .

[0115] The length of the box body 2100a is L1, and the width of the box body 2100a is L2, satisfying the relationship: L1>L2. Specifically, the length of the box body 2100a is the maximum dimension of the box body 2100a in its own length direction (i.e., the X-direction shown in the figure), and the width of the box body 2100a is the maximum dimension of the box body 2100a in its own width direction (i.e., the X-direction shown in the figure).

[0116] The width dimension of the placement space 1000a is L3, satisfying the relationship: L1>L3≥L2. In this way, when the material box body 2000a is assembled on the assembly frame 1000, the width direction of the box body 2100a needs to be parallel to the width direction of the placement space 1000a (that is, the Y direction shown in the figure), so that the material box body 2000a can only be placed in the placement space 1000a in a single direction (that is, the width direction of the box body 2100a needs to be parallel to the width direction of the placement space 1000a). For example, when the material box body 2000a is assembled on the assembly frame 1000 in a state where the length direction of the box body 2100a is parallel to the width direction of the placement space 1000a, due to L1>L3, the assembly frame 1000 interferes with the box body 2100a, so that the material box body 2000a cannot be assembled on the assembly frame 1000. This can serve as a reminder to the user, reminding the user to change the assembly direction of the material box body 2000a, so that the user can assemble the material box body 2000a on the assembly frame 1000 in the correct assembly direction, thereby ensuring the assembly stability of the material box body 2000a and the assembly frame 1000, and preventing the material box body 2000a from being separated from the assembly frame 1000.

[0117] In addition, since effective feedback can be given to the user when the user assembles the material box body 2000a on the assembly frame 1000 in an incorrect manner, the user can only assemble it on the assembly frame 1000 in a correct manner. In this way, when the user assembles multiple material box bodies 2000a on the assembly frame 1000, it can be ensured that the user efficiently assembles multiple material box bodies 2000a on the assembly frame 1000 in a correct manner, thereby ensuring the stability of each material box body 2000a.

[0118] It should also be noted that the width of the placement space 1000a can be greater than or equal to the width of the box body 2100a to ensure that the material holding box 2000a can be assembled on the assembly frame 1000. When the width of the placement space 1000a is equal to the width of the box body 2100a, the outer peripheral wall of the box body 2100a contacts the assembly frame 1000. For example, L1 = 175 mm, L2 = 165 mm, and L3 = 165 mm. When the width of the placement space 1000a is greater than the width of the box body 2100a, the outer peripheral wall of the box body 2100a can be spaced apart from the assembly frame 1000. Considering the production process, in some embodiments, the width of the placement space 1000a is greater than the width of the box body 2100a. This reduces the production precision of the material holding box 2000a and the assembly frame 1000, thereby reducing production costs. For example, L1 = 175 mm, L2 = 164 mm, and L3 = 165 mm. Furthermore, the length of the placement space 1000 a is L4, and the value of L4 can be specifically set according to the number of material boxes 2000 a required to be placed in the assembly frame 1000 .

[0119] In summary, according to the material holding assembly of the present application, the structure of the assembly frame 1000 is simple, and the problem of sanitary blind spots is avoided, which facilitates the user to clean the assembly frame 1000. It can also ensure the assembly stability of the material holding box body 2000a and the assembly frame 1000, and prevent the material holding box body 2000a from being separated from the assembly frame 1000. In addition, the material holding assembly of the present application can also ensure that the user can efficiently assemble multiple material holding boxes 2000a in the assembly frame 1000 in a correct manner, ensuring the stability of each material holding box body 2000a.

[0120] In one embodiment, the power assembly 110 includes a driving pump, a buffer 112 and a driver; the driving pump is connected to the liquid outlet pipe 120; the buffer 112 is connected to the liquid outlet pipe 120 and is located at the outlet end of the driving pump; the driver is electrically connected to the control motherboard 300 and the driving pump at the same time, and is used to control the action of the driving pump according to the liquid outlet signal triggered by the control motherboard 300; wherein, the driving pump arranged on the liquid outlet pipe 120 connected to the first liquid storage container 602 is a peristaltic pump 111, the driving pump arranged on the liquid outlet pipe 120 connected to the second liquid storage container 601 is a peristaltic pump 111, and the driving pump arranged on the liquid outlet pipe 120 connected to the third liquid storage container 603 is a gear pump 710.

[0121] In one embodiment, the peristaltic pump 111 is electrically connected to the control board 300. When in operation, the peristaltic pump 111 enables the liquid outlet pipe 120 to draw liquid material from the liquid storage container. In the liquid outlet control system 10 of the present application, the peristaltic pump 111 is used to transport the liquid material, and the peristaltic pump 111 and the cleaning pump 221 cooperate to clean each group of liquid outlet structures 100.

[0122] The peristaltic pump 111 is the power source for the liquid outlet structure 100. It controls the flow rate of the liquid material in the liquid outlet pipe 120. Furthermore, the peristaltic pump 111 is isolated from the liquid material in the liquid outlet pipe 120, meaning it does not come into contact with the liquid material. This prevents contamination of the liquid material by the peristaltic pump 111, preventing bacterial growth and ensuring safety. Furthermore, the peristaltic pump 111 offers high delivery accuracy and is easy to operate.

[0123] In one embodiment, the buffer member 112 has a certain elasticity and can act as a buffer. The buffer member 112 can change in volume according to changes in water pressure, thereby creating a buffering effect. When the liquid outlet pipe 120 conveys liquid material, the buffer member 112 can utilize the buffering effect to buffer the conveying speed of the liquid material, prevent the liquid material from being conveyed too quickly, and ensure that the liquid material flows slowly and steadily in the liquid outlet pipe 120, thereby preventing the liquid material from splashing.

[0124] In this embodiment, the buffer member 112 is a buffer ball. The buffering effect of the buffer ball can buffer the conveying speed of the liquid material and prevent the liquid material from being conveyed too quickly. Of course, in other embodiments of the present application, the buffer member 112 can also be a damper or other structure that can provide a buffering effect.

[0125] In one embodiment, the buffer member 112 is made of an elastic material. In this way, the buffer member 112 can use its elastic properties to play a buffering role, thereby buffering the conveying speed of the liquid material and preventing the liquid material from being conveyed too quickly. Optionally, the buffer member 112 is made of an elastic material such as rubber or plastic.

[0126] In one embodiment, the liquid outlet pipe 120 is a hose. This facilitates the routing of the liquid outlet pipe 120 within the cabinet 1. Of course, in the liquid outlet control system 10 of this application, all pipes are hoses. In other words, the cleaning pipe 222 and the cleaning branch pipe 231 are all hoses.

[0127] In one embodiment, the power assembly 110 further includes a driver electrically connected to the control board 300 and the peristaltic pump 111. The driver controls the operation of the corresponding peristaltic pump 111 based on the liquid discharge signal triggered by the control board 300. The driver is the controller of the power assembly 110 and is electrically connected to the control board 300. The driver receives the liquid discharge signal from the control board 300 through the driver, thereby controlling the operation of the peristaltic pump 111 based on the liquid discharge signal.

[0128] The liquid dispenser of this application is used in conjunction with a cash register. Operators can use the cash register to place orders, and the order placement app can also be connected to the cash register. After consumers place their orders through the app, the order information is automatically stored in the cash register. The liquid dispenser is connected to the cash register, and after an order is placed, the cash register can retrieve the order information and synchronously feed it back to the liquid dispenser.

[0129] The dispenser then receives the order information and adds it to the order list. The dispenser has a display that shows the order list. The operator then clicks the "Make" button on the display, or scans the pop-up "Make" section and clicks "Make Dispenser." The dispenser then begins preparing the drink according to the order information.

[0130] The operation screen then transmits the order information to the control board 300, which analyzes the order information and generates liquid discharge information for the liquid dispenser. The control board 300 then sends the liquid discharge information to the corresponding power assembly 110, so that the power assembly 110 can extract the liquid material from the corresponding storage container through the liquid discharge pipe 120.

[0131] Furthermore, after receiving the liquid discharge information, the power assembly 110 discharges liquid according to the time specified in the liquid discharge information, such as the time after which the power assembly 110 is activated to pump liquid. In this way, each power assembly 110 can operate according to the control timing indicated by the liquid discharge information transmitted by the control mainboard 300, thereby achieving the sequential preparation of multiple cups of beverages.

[0132] In one embodiment, a gear pump 710 is the power source for driving the syrup along the liquid storage tube. Different pumping methods are used to address the characteristics of different materials. Due to the high density of syrup, bacteria cannot grow within it. Therefore, even if the gear pump 710 comes into contact with the syrup while driving the syrup, this does not affect the food safety and quality of the syrup. Furthermore, the gear pump 710's precise delivery volume allows it to precisely deliver the required amount of syrup, ensuring the desired taste and flavor of the prepared beverage. Other materials are prone to bacterial growth and present bacterial issues, so peristaltic pump 111 is used for delivery. Although the delivery volume is not as precise as that of the gear pump 710, other materials (such as water and tea) do not significantly affect the taste of syrup. This demonstrates that the above design specifically selects different delivery methods based on the characteristics of different materials, representing a creative design solution.

[0133] In one embodiment, the liquid dispensing machine includes:

[0134] The refrigeration component 1200 is arranged on the side of the refrigeration chamber 401 and is connected to the refrigeration chamber 401 for supplying cold air to the refrigeration chamber 401. The interior of the ingredient cabinet 2000 is provided with a receiving cavity 2100.

[0135] The conveying structure 3000 connects the refrigerating chamber 401 and the accommodating cavity 2100 , and is used to convey the cold air in the refrigerating chamber 401 to the accommodating cavity 2100 .

[0136] In one embodiment, the delivery structure 3000 includes a fan 3200 and an output pipe 3100. The output pipe 3100 is disposed in the accommodating chamber 2100. One end of the output pipe 3100 extends into the refrigerating chamber 401, and the other end of the output pipe 3100 is located in the accommodating chamber 2100. The fan 3200 is disposed in the output pipe 3100 and is used to deliver cold air from the refrigerating chamber 401 to the accommodating chamber 2100 through the output pipe 3100. And / or,

[0137] The liquid outlet pipe 120 connected to the second liquid storage container 601 extends into the accommodating chamber 2100 and is connected to the second liquid storage container 601 and the liquid outlet head through the accommodating chamber 2100.

[0138] In one embodiment, the output pipe 3100 includes an inlet pipe 3110 and a delivery pipe 3120. The inlet pipe 3110 is disposed at one end of the delivery pipe 3120 and is located in the refrigeration chamber 401. The delivery pipe 3120 is located in the accommodating cavity 2100 and extends toward the top of the accommodating cavity 2100. The cross-sectional dimension of the inlet pipe 3110 in the refrigeration chamber 401 is larger than the cross-sectional dimension at the connection between the inlet pipe 3110 and the delivery pipe 3120. And / or,

[0139] The conveying structure 3000 further includes a distribution component 3300, which is disposed at one end of the output pipe 3100 away from the refrigeration chamber 401; the distribution component 3300 and the inner wall of the ingredient cabinet 2000 are surrounded by a distribution space, which connects the output pipe 3100 and the accommodating chamber 2100; and / or,

[0140] The fan 3200 is arranged at at least one end of the output pipe 3100 or in the cavity of the output pipe 3100; there is a preset angle between the fan 3200 and the central axis of the output pipe 3100, and the preset angle ranges from 30° to 45°.

[0141] The conveying structure 3000 can convey the cold air in the refrigeration chamber 401 to the accommodating chamber 2100 of the ingredient cabinet 2000, allowing the accommodating chamber 2100 to borrow the cold air from the refrigeration chamber 401. In this way, the cold air in the accommodating chamber 2100 can cool the liquid materials therein and the solid materials contained in the material box 2000a in the storage space 2200. This enables the solid and liquid materials in the material box 2000a to be stored and conveyed at low temperatures, preventing material deterioration and ensuring safety. At the same time, there is no need to install a separate refrigeration device in the accommodating chamber 2100, reducing the complexity and cost of the cabinet 1 structure and facilitating the promotion and application of the liquid dispenser.

[0142] In one embodiment, a cabinet 1 includes a refrigerator, a batching cabinet 2000, and a conveying structure 3000. The refrigerator includes a refrigerating chamber 401 and a refrigeration assembly 1200. The refrigerating assembly 1200 is disposed on the side of the refrigerating chamber 401 and communicates with the refrigerating chamber 401, supplying cold air to the refrigerating chamber 401. The batching cabinet 2000 is disposed above the refrigerator and includes a connecting accommodating cavity 2100 and a storage space 2200. The storage space 2200 is used to store a container 2000a. The conveying structure 3000 connects the refrigerating chamber 401 and the accommodating cavity 2100 and is used to convey cold air from the refrigerating chamber 401 to the accommodating cavity 2100.

[0143] Refrigeration assembly 1200 is a device for providing cold air. Refrigeration assembly 1200 is located on the side of refrigeration chamber 401 and generates cold air when in operation. Refrigeration chamber 401 is a cold-keeping space, and second liquid storage container 601 is stored in refrigeration chamber 401 to refrigerate the second liquid material in second liquid storage container 601. The output end of refrigeration assembly 1200 is connected to refrigeration chamber 401, and refrigeration assembly 1200 can deliver cold air to refrigeration chamber 401 to cool refrigeration chamber 401 and maintain a low-temperature environment. This allows refrigeration chamber 401 to refrigerate the second liquid material in second liquid storage container 601.

[0144] The ingredient cabinet 2000 is located at the rear edge of the refrigerator's top and extends upward. The cabinet 2000 is hollow, with a hollow chamber 2100. It also has a storage space 2200, located above the refrigerator and in front of the cabinet. Multiple material boxes 2000a can be placed in the storage space 2200. When preparing drinks, the operator can remove solid materials from the boxes 2000a in the storage space 2200, making it easier to remove them.

[0145] The accommodating chamber 2100 of the ingredient cabinet 2000 communicates with the storage space 2200, and the conveying structure 3000 connects the refrigerating chamber 401 with the accommodating chamber 2100. In other words, the refrigerating chamber 401 and the accommodating chamber 2100 are independently provided, with the conveying structure 3000 establishing a connecting passage between the refrigerating chamber 401 and the accommodating chamber 2100. The conveying structure 3000 can convey the cold air in the refrigerating chamber 401 to the accommodating chamber 2100, thereby maintaining a refrigerated environment in the accommodating chamber 2100.

[0146] In this way, the accommodating cavity 2100 can transport cold air into the storage space 2200, so that the cold air can refrigerate the material box 2000a and the solid materials therein in the storage space 2200. In this way, the solid materials can also be stored in a refrigerated environment, achieving low-temperature storage of the solid materials in a refrigerated environment, preventing the solid materials from deteriorating at room temperature, and ensuring safety.

[0147] Furthermore, the accommodating chamber 2100 can utilize the cold air from the refrigerating chamber 401 through the conveying structure 3000. Without affecting the refrigeration of the second liquid storage container 601 in the refrigerating chamber 401, the cold air from the refrigerating chamber 401 can be used to refrigerate the material storage box 2000a in the storage space 2200 of the ingredient cabinet 2000. This eliminates the need for dedicated refrigeration equipment in the ingredient cabinet 2000 and the accommodating chamber 2100. This significantly reduces the structural complexity of the ingredient cabinet 2000 and reduces the production cost of the entire liquid dispenser.

[0148] The conveying structure 3000 connects the refrigeration chamber 401 with the accommodating cavity 2100 to convey the cold air from the refrigeration chamber 401 to the accommodating cavity 2100, thereby maintaining the mixing cabinet 2000 in a refrigerated environment. This means that the accommodating cavity 2100 can utilize the cold air from the refrigeration chamber 401. In this way, the cold air from the accommodating cavity 2100 cools the liquid materials therein as well as the solid materials contained in the material storage box 2000a in the storage space 2200. This allows the solid and liquid materials in the material storage box 2000a to be stored and conveyed at low temperatures, preventing material deterioration and ensuring safety. Furthermore, there is no need to install a separate refrigeration device in the accommodating cavity 2100, reducing the complexity and cost of the cabinet 1 structure and facilitating the widespread application of the liquid dispenser.

[0149] In one embodiment, one end of the conveying structure 3000 is connected to the refrigerating chamber 401, and the other end of the conveying structure 3000 is connected to the accommodating chamber 2100. The bottom of the conveying structure 3000 is connected to the refrigerating chamber 401, and the top of the conveying structure 3000 is connected to the accommodating chamber 2100. In this way, the conveying structure 3000 can convey cold air from the refrigerating chamber 401 to the accommodating chamber 2100, thereby refrigerating the accommodating chamber 2100 and the storage space 2200.

[0150] In one embodiment, the conveying structure 3000 is partially located in the accommodating chamber 2100 and partially located in the refrigerating chamber 401. The lower portion of the conveying structure 3000 is located in the refrigerating chamber 401, while the upper portion of the conveying structure 3000 is located in the accommodating chamber 2100. This allows the conveying structure 3000 to establish a passage between the refrigerating chamber 401 and the accommodating chamber 2100, enabling the delivery of cold air while preventing cold air from leaking through the gap between the refrigerating cabinet and the ingredient cabinet 2000, thereby reducing energy consumption.

[0151] Of course, in other embodiments of the present application, the delivery structure 3000 may also be located in the accommodating chamber 2100, with the top of the refrigerator having an opening that communicates with the refrigerating chamber 401, and the delivery structure 3000 being sealedly connected to the opening. This also enables the delivery structure 3000 to deliver cold air to the accommodating chamber 2100.

[0152] In one embodiment, refrigeration assembly 1200 includes a compressor, a condenser, an evaporator, and a circulation pipeline. The circulation pipeline connects the compressor, condenser, and evaporator to form a refrigeration circuit. When in operation, refrigeration assembly 1200 generates cold air and delivers this cold air to refrigerated compartment 401. Optionally, refrigeration assembly 1200 also includes an evaporation fan, which is located on the side of the evaporator to achieve evaporative ventilation in refrigeration assembly 1200.

[0153] Optionally, refrigeration assembly 1200 further includes a plurality of heat dissipation holes, each of which is arranged corresponding to refrigeration assembly 1200. Heat generated during operation of refrigeration assembly 1200 is dissipated through the heat dissipation holes, thereby reducing the operating temperature of the compressor and ensuring the performance of refrigeration assembly 1200. It is worth noting that the shape and layout of the heat dissipation holes are, in principle, not limited, as long as they can achieve heat dissipation. Optionally, the plurality of heat dissipation holes are arranged in rows and columns. Optionally, the heat dissipation holes are circular, square, oblong, elliptical, or other regular or irregular shapes.

[0154] In one embodiment, the cabinet 1 further includes a controller, which is disposed within the cabinet 1 and electrically connects to the various electrical components of the cabinet 1 to control the components to perform corresponding actions. The controller is electrically connected to the refrigeration assembly 1200 to control the refrigeration assembly 1200 to perform refrigeration operations. The controller is also electrically connected to the operating console 50. After an operator manipulates the operating console 50, the controller can perform liquid discharge operations.

[0155] In one embodiment, the ingredient cabinet 2000 includes a main cabinet and a cover plate 2300. The cover plate 2300 is arranged on the front side of the main cabinet and is surrounded by the main cabinet to form a accommodating cavity 2100. The liquid outlet pipe 120 connected to the second liquid storage container 601 extends into the accommodating cavity 2100, and is connected to the second liquid storage container 601 and the liquid discharge head through the accommodating cavity 2100, and part of the conveying structure 3000 is located in the accommodating cavity 2100.

[0156] Because the liquid outlet pipe 120 connected to the second liquid storage container 601 extends into the accommodating chamber 2100 and is connected to the second liquid storage container 601 and the liquid discharging head via the accommodating chamber 2100, the cold air in the accommodating chamber 2100 can refrigerate the liquid outlet pipe 120 connected to the second liquid storage container 601. This means that the second liquid material in the liquid outlet pipe 120 connected to the second liquid storage container 601 is also kept in a refrigerated environment. This allows for low-temperature storage and transportation of the second liquid material, preventing deterioration of the liquid material and ensuring safety.

[0157] The power pump is fixedly mounted on the inner wall of the accommodating chamber 2100, and the liquid outlet pipe 120 is located in the accommodating chamber 2100 and routed within the cabinet 1. This eliminates the need for the power pump to be located within the refrigerating chamber 401. This allows the liquid outlet pipe 120 to be cooled while reducing the space occupied by the power pump within the refrigerating chamber 401, thereby improving the space utilization of the accommodating chamber 2100.

[0158] In one embodiment, the delivery structure 3000 includes a fan 3200 and an output duct 3100. The output duct 3100 is disposed in the accommodating chamber 2100. One end of the output duct 3100 extends into the refrigerating chamber 401, and the other end of the output duct 3100 is located in the accommodating chamber 2100. The fan 3200 is disposed in the output duct 3100 and is used to deliver cold air from the refrigerating chamber 401 to the accommodating chamber 2100 via the output duct 3100.

[0159] The output duct 3100 is the main duct for transporting cold air. One end of the output duct 3100 extends into the refrigerating chamber 401, and the other end of the output duct 3100 is located in the accommodating chamber 2100. This connects the refrigerating chamber 401 with the accommodating chamber 2100. The fan 3200, the power source for the conveying structure 3000, is located in the output duct 3100. When in operation, the fan 3200 generates a suction force, drawing the cold air from the refrigerating chamber 401 into the output duct 3100, where it is then transported to the accommodating chamber 2100.

[0160] In this way, the cold air in the accommodating chamber 2100 can refrigerate the liquid material in the liquid outlet pipe 120. In addition, the accommodating chamber 2100 can also transport the cold air to the storage space 2200, so that the cold air can refrigerate the material holding box 2000a and the solid material therein in the storage space 2200. In this way, the liquid material and the solid material can be stored in a refrigerated environment, achieving low-temperature storage and transportation of the liquid material and low-temperature storage of the solid material, preventing the liquid material and the solid material from deteriorating at room temperature and ensuring safety.

[0161] In one embodiment, the output pipe 3100 includes an inlet pipe 3110 and a delivery pipe 3120 . The inlet pipe 3110 is disposed at one end of the delivery pipe 3120 and is located in the refrigeration chamber 401 . The delivery pipe 3120 is located in the accommodating cavity 2100 and extends toward the top of the accommodating cavity 2100 .

[0162] The inlet pipe 3110 is arranged at the bottom of the delivery pipe 3120 . The inlet pipe 3110 is located in the refrigerating chamber 401 . The delivery pipe 3120 is located in the accommodating cavity 2100 . The inlet pipe 3110 and the delivery pipe 3120 are connected at the connection point between the refrigerating chamber 401 and the accommodating cavity 2100 .

[0163] When the fan 3200 is working, the cold air in the cold storage chamber 401 can enter the inlet pipe 3110, enter the delivery pipe 3120 through the inlet pipe 3110, and then enter the accommodating cavity 2100 through the delivery pipe 3120 to refrigerate the pipeline structure in the accommodating cavity 2100 and the material box body 2000a in the storage space 2200.

[0164] In one embodiment, the inlet pipe 3110 and the delivery pipe 3120 are provided separately and are fastened together using screws or other means. Optionally, the output pipe 3100 further includes a seal disposed between the inlet pipe 3110 and the delivery pipe 3120 to ensure a tight seal at the connection between the two and prevent cold air from leaking from the connection between the inlet pipe 3110 and the delivery pipe 3120.

[0165] Of course, in other embodiments of the present application, the inlet pipe 3110 and the delivery pipe 3120 may also be an integrated structure. In one embodiment, the delivery pipe 3120 is arranged in a vertical direction. This allows for cold air delivery while reducing the space occupied by the delivery pipe 3120, facilitating the layout of the piping structure within the accommodating chamber 2100. Of course, in other embodiments of the present application, the delivery pipe 3120 may also be arranged at an angle, etc.

[0166] In one embodiment, the delivery tube 3120 extends to the top of the accommodating chamber 2100. In other words, the end of the delivery tube 3120 away from the inlet tube 3110 is located at the top of the accommodating chamber 2100. This allows the delivery tube 3120 to deliver cold air to the accommodating chamber 2100, where it can sink from the top of the accommodating chamber 2100, thereby better refrigerating the piping structure within the accommodating chamber 2100.

[0167] In one embodiment, the cross-sectional dimension of the inlet pipe 3110 located in the refrigerated compartment 401 is larger than the cross-sectional dimension at the junction of the inlet pipe 3110 and the delivery pipe 3120. In other words, the inlet pipe 3110 is a flared pipe, with the cross-sectional dimension of the inlet pipe 3110 gradually decreasing from bottom to top. This facilitates the entry of cold air into the delivery pipe 3120.

[0168] In one embodiment, the output pipe 3100 is made of sheet metal. In other words, the output pipe 3100 is a sheet metal pipe. This ensures the structural strength of the output pipe 3100 and reduces corrosion of the output pipe 3100, thereby ensuring the performance of the output pipe 3100.

[0169] In one embodiment, the conveying structure 3000 also includes a distribution component 3300, which is arranged at one end of the output pipe 3100 away from the refrigeration chamber 401; the distribution component 3300 and the inner wall of the ingredient cabinet 2000 are arranged to form a distribution space, and the distribution space connects the output pipe 3100 and the accommodating cavity 2100.

[0170] The distribution member 3300 is disposed at the end of the delivery tube 3120 away from the inlet tube 3110. Furthermore, the distribution member 3300 abuts the inner wall of the accommodating chamber 2100 to enclose a distribution space. In this manner, the delivery tube 3120 can first deliver the cold air to the distribution space, and then, through the distribution member 3300, deliver the cold air to the accommodating chamber 2100, allowing the cold air delivered by the delivery tube 3120 to enter the accommodating chamber 2100.

[0171] In one embodiment, the distribution component 3300 has a plurality of distribution holes 3310 that penetrate the distribution component 3300 to connect the distribution space with the accommodating chamber 2100. The distribution holes 3310 penetrate the distribution component 3300 vertically to connect the distribution space with the accommodating chamber 2100.

[0172] After the delivery pipe 3120 delivers the cold air to the distribution space, the cold air can enter the accommodating cavity 2100 through the distribution hole 3310 of the distribution component 3300 to refrigerate the pipeline structure in the accommodating cavity 2100. At the same time, the cold air can also enter the storage space 2200 to refrigerate the material box body 2000a in the storage space 2200.

[0173] In one embodiment, the plurality of distribution holes 3310 are evenly and / or non-uniformly distributed on the distribution component 3300. That is, the distribution holes 3310 can be evenly arranged on the distribution component 3300, or the distribution holes 3310 can be non-uniformly distributed on the distribution component 3300, or some of the distribution holes 3310 can be evenly distributed on the distribution component 3300, while some of the distribution holes 3310 can be non-uniformly distributed on the distribution component 3300.

[0174] In this embodiment, the multiple distribution holes 3310 are distributed more sparsely on the side close to the delivery tube 3120 and more densely on the side away from the delivery tube 3120. Thus, when the delivery tube 3120 delivers cold air to the distribution space, the cold air first enters the distribution space close to the delivery tube 3120 and then flows to the side away from the delivery tube 3120. This sparse and dense arrangement of the distribution holes 3310 allows the cold air in the distribution space to flow as evenly as possible into the accommodating cavity 2100, thereby achieving uniform cooling of the piping structure.

[0175] In one embodiment, the liquid discharge machine includes a cleaning structure 200, which includes a cleaning component 220, a cleaning tube group 210 and a cleaning tube group 230. The cleaning component 220 includes a cleaning pipeline 222 and a cleaning pump 221. The cleaning pump 221 is arranged in the cleaning pipeline 222. The cleaning pipeline 222 includes a plurality of cleaning branches 231 arranged in parallel. The cleaning tube group 210 is connected to one end of the cleaning component 220 for transporting cleaning liquid to the cleaning component 220. One end of each cleaning branch 231 is connected to the other end of the cleaning pipeline 222, and the other end is respectively connected to the inlet end of the liquid discharge structure 100. The cleaning tube group 230 also includes a cleaning main pipe 232. One end of the cleaning main pipe 232 is connected to the cleaning pipeline 222. The cleaning main pipe 232 is respectively connected to each cleaning branch pipe 231. The driving force of the cleaning pump 221 is greater than the driving force of the power component 110.

[0176] In one embodiment, the cleaning pipe group 210 includes a first delivery pipe 3120 and a first control valve 212. One end of the first delivery pipe 3120 is connected to the tap water inlet 403 of the liquid discharge machine, and the other end of the first delivery pipe 3120 is connected to the cleaning pipe 222. The first delivery pipe 3120 is used to deliver tap water. The first control valve 212 is set on the first delivery pipe 3120 to control the on and off of the first delivery pipe 3120.

[0177] In one embodiment, the cleaning pipe group 210 includes a second delivery pipe 3120 and a second control valve 214. One end of the second delivery pipe 3120 is connected to the disinfectant storage barrel of the liquid discharge machine, and the other end of the second delivery pipe 3120 is connected to the cleaning pipe 222. The second delivery pipe 3120 is used to transport the disinfectant. The second control valve 214 is set on the second delivery pipe 3120 to control the on and off of the second delivery pipe 3120.

[0178] In one embodiment, the cleaning pipe group 210 includes a third delivery pipe 3120 and a third control valve 216. One end of the third delivery pipe 3120 is connected to the descaling agent storage barrel of the liquid discharge machine, and the other end of the third delivery pipe 3120 is connected to the cleaning pipe 222. The third delivery pipe 3120 is used to transport the descaling agent. The third control valve 216 is set on the third delivery pipe 3120 to control the on and off of the third delivery pipe 3120.

[0179] In one embodiment, the cleaning pipe group 210 includes a fourth delivery pipe 3120 and a fourth control valve 218. One end of the fourth delivery pipe 3120 is connected to the air inlet 402 of the liquid discharge machine, and the other end of the fourth delivery pipe 3120 is connected to the cleaning pipe 222. The fourth delivery pipe 3120 is used to deliver air, and the fourth control valve 218 is set on the fourth delivery pipe 3120 to control the on and off of the fourth delivery pipe 3120.

[0180] After the liquid outlet structure 100 delivers liquid material, some liquid material may remain in the liquid outlet structure 100. If the liquid outlet is closed, the remaining liquid material in the liquid outlet structure 100 may deteriorate, necessitating cleaning of the liquid outlet structure 100. The cleaning structure 200 is connected to the inlet of each group of liquid outlet structures 100 and can clean each group of liquid outlet structures 100 to remove any remaining liquid material and ensure effective cleaning.

[0181] Specifically, cleaning structure 200 includes cleaning pipe assembly 210, cleaning assembly 220, and cleaning pipe assembly 230. Cleaning pipe assembly 210 and cleaning pipe assembly 230 are located at both ends of cleaning assembly 220. Cleaning pipe assembly 210 is a pipeline for transporting cleaning fluid, which includes but is not limited to tap water, descaling agent, disinfectant, air, etc., and can also be other liquids or gases used in the cleaning process.

[0182] The cleaning tube assembly 230 is a component that communicates with each set of liquid outlet structures 100 and is connected to the inlet end of each set of liquid outlet structures 100. The cleaning assembly 220 provides power for cleaning the liquid outlet structures 100, thereby transporting cleaning liquid from the cleaning tube assembly 210 through the cleaning tube assembly 230 to each set of liquid outlet structures 100, thereby cleaning each set of liquid outlet structures 100 and removing residual liquid material therein.

[0183] The cleaning pipe assembly 230 includes multiple cleaning branches 231, one for each liquid outlet structure 100. Each cleaning branch 231 is connected to the inlet of the corresponding liquid outlet structure 100. The cleaning assembly 220 includes a cleaning pipeline 222 and a cleaning pump 221. The cleaning pump 221 is disposed in the cleaning pipeline 222 and provides power to the flow of cleaning liquid in the cleaning pipeline 222. One end of the cleaning pipeline 222 is connected to the cleaning pipe assembly 210, and the other end of the cleaning pipeline 222 is connected to each cleaning branch 231.

[0184] The present application utilizes a cleaning pump 221 to pump the cleaning liquid. This cleaning pump 221 maintains a positive pressure throughout the entire piping system (including the cleaning piping 222, each cleaning branch pipe 231, and each set of liquid outlet structures 100). This allows the cleaning liquid to flow stably within the piping system, preventing air leaks and internal air leakage, achieving thorough cleaning of the liquid outlet structures 100 and ensuring effective cleaning results. Furthermore, the piping system has a simple structure, facilitating cleaning operations.

[0185] During cleaning, cleaning liquid is sent into the cleaning tube group 210, and the cleaning pump 221 is turned on. The cleaning pump 221 can pump the cleaning liquid into the cleaning pipeline 222, and then enter each cleaning branch pipe 231 through the cleaning pipeline 222. Then, the cleaning liquid can enter each group of liquid outlet structures 100 through the corresponding cleaning branch pipe 231. The cleaning liquid can clean the liquid outlet structure 100 during the flow of the liquid outlet structure 100, and the cleaning liquid is discharged from the liquid outlet port 501.

[0186] Moreover, after the cleaning structure 200 cleans each group of liquid outlet structures 100, the cleaning liquid is discharged from the liquid outlet port 501. At this time, the cleaning liquid can also clean the liquid outlet port 501, solving the current problem of difficulty in cleaning the liquid outlet port 501, facilitating the cleaning operation of the liquid outlet port 501, and ensuring that the liquid outlet port 501 is clean and hygienic.

[0187] The piping system of the above embodiment uses a cleaning pipe 222 to automatically clean each group of liquid outlet structures 100. During cleaning, the cleaning pump 221 transports the cleaning liquid transported by the cleaning pipe group 210 to each cleaning branch pipe 231, and then enters the corresponding liquid outlet structure 100 through the cleaning branch pipe 231, thereby cleaning each group of liquid outlet structures 100 and preventing residual liquid material in the liquid outlet structure 100. At the same time, when the cleaning pump 221 is in operation, it can put the cleaning pipe 222, the cleaning branch pipe 231, and the liquid outlet structure 100 in a positive pressure state, and ensure that the cleaning liquid can flow stably in the cleaning pipe 222, the cleaning branch pipe 231, and the liquid outlet structure 100, preventing air leakage, achieving thorough cleaning, and ensuring the cleaning effect. Moreover, the piping system has a simple structure, which is convenient for application in a liquid outlet machine, simplifying the cleaning process of the liquid outlet machine and facilitating the cleaning operation.

[0188] There are ten groups of liquid outlet structures 100, and ten liquid storage containers, including six second liquid storage containers 601 and four first liquid storage containers 602. Six of the liquid outlet structures 100 are connected to the second liquid storage containers 601, and four of the liquid outlet structures 100 are connected to the first liquid storage containers 602. Of course, in other embodiments of the present application, the number of liquid outlet structures 100 can be other, and the number of second liquid storage containers 601 and first liquid storage containers 602 can also be adjusted.

[0189] It is worth noting that the principle of the liquid outlet structure 100 transporting the liquid material in the second liquid storage container 601 is essentially the same as the principle of transporting the liquid material in the first liquid storage container 602. In this application, only the liquid outlet structure 100 transporting the liquid material in the liquid storage container is used as an example for explanation.

[0190] In the piping system of the present application, each pipeline is a hose. In other words, the cleaning pipeline 222, the cleaning branch pipe 231, etc. are all hoses. In one embodiment, the driving force of the cleaning pump 221 is greater than the driving force of the power assembly 110. In other words, the driving force of the cleaning pump 221 is greater than the driving force of the peristaltic pump 111. Like this, the pipelines of the entire piping system are all positive pressure to prevent air leakage. It is understandable that due to the poor pump power of the peristaltic pump 111, it is easy to pump out the cleaning liquid for the descaling agent, and it is easy to draw air into the pipeline from the leak point. After the present application is provided with the cleaning pump 221 in the cleaning pipeline 222, the cleaning pump 221 can provide a larger driving force of active drive, so that the descaling agent can be actively and smoothly flowed in the liquid outlet structure 100, generating a positive positive pressure to avoid air leakage.

[0191] In one embodiment, the cleaning pump 221 is an impeller pump. When the impeller pump is in operation, the impeller can drive the fluid therein to rotate at high speed, thereby achieving the purpose of conveying the fluid. After the present application uses the impeller pump as the cleaning pump 221, it can provide a greater driving force for active driving.

[0192] In one embodiment, the cleaning structure 200 further includes a pressure reducing valve, which is disposed in the cleaning pipeline 222 or the cleaning branch pipe 231. The pressure reducing valve can reduce the water pressure in the pipeline system to prevent the cleaning pipeline 222 or the cleaning branch pipe 231 from bursting due to excessive water pressure, thereby ensuring safety.

[0193] In one embodiment, the cleaning pipe assembly 230 further includes a cleaning main pipe 232 . One end of the cleaning main pipe 232 is connected to the cleaning pipeline 222 . The cleaning main pipe 232 is connected to each of the cleaning branch pipes 231 .

[0194] The main cleaning pipe 232 is disposed between the cleaning pipeline 222 and each cleaning branch pipe 231, and the main cleaning pipe 232 establishes a connection between the cleaning pipeline 222 and each cleaning branch pipe 231. The cleaning liquid in the cleaning pipeline 222 can be transported to the main cleaning pipe 232, distributed to each cleaning branch pipe 231 by the main cleaning pipe 232, and then transported to each group of liquid outlet structures 100 through the cleaning branch pipes 231.

[0195] Of course, in other embodiments of the present application, the cleaning pipe group 230 may also be directly provided with a plurality of cleaning branch pipes 231 , and the cleaning branch pipes 231 are directly connected to the output end of the cleaning pipeline 222 .

[0196] In one embodiment, the cleaning pipe group 210 includes a first delivery pipe 3120 and a first control valve 212. One end of the first delivery pipe 3120 is connected to the tap water inlet 403 of the liquid discharge machine, and the other end of the first delivery pipe 3120 is connected to the cleaning pipe 222. The first delivery pipe 3120 is used to deliver tap water. The first control valve 212 is set on the first delivery pipe 3120 to control the on and off of the first delivery pipe 3120.

[0197] The first delivery pipe 3120 is used to deliver tap water. The cabinet 1 has a tap water inlet 403, which is connected to an external tap water source via a pipe. One end of the first delivery pipe 3120 is connected to the tap water inlet 403, and the other end is connected to the end of the cleaning pipe 222 away from the cleaning branch pipe 231. In this way, the first delivery pipe 3120 can deliver tap water to the cleaning pipe 222, and then enter each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231.

[0198] The first control valve 212 is disposed on the first delivery pipe 3120. The first control valve 212 can control the opening and closing of the first delivery pipe 3120. When the first control valve 212 is open, tap water can enter the first delivery pipe 3120, thereby being delivered to the liquid outlet structure 100 through the cleaning pipe 222 and the cleaning branch pipe 231. When the first control valve 212 is closed, the first delivery pipe 3120 is disconnected, and tap water cannot enter the liquid outlet structure 100.

[0199] Furthermore, the first control valve 212 is electrically connected to the control mainboard 300, and is automatically opened or closed by the control mainboard 300. Optionally, the first control valve 212 is a solenoid valve. During cleaning, the control mainboard 300 controls the first control valve 212 to open. At this time, tap water flows into the first delivery pipe 3120 and enters each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. As the tap water flows through the liquid outlet structure 100, it flushes the liquid outlet pipe 120, thereby cleaning the liquid outlet structure 100.

[0200] In one embodiment, the cleaning tube group 210 also includes a second delivery tube 3120 and a second control valve 214. One end of the second delivery tube 3120 is connected to the disinfectant storage barrel of the liquid dispensing machine, and the other end of the second delivery tube 3120 is connected to the cleaning tube 222. The second delivery tube 3120 is used to transport the disinfectant. The second control valve 214 is arranged on the second delivery tube 3120 to control the on and off of the second delivery tube 3120.

[0201] The second delivery pipe 3120 is used to deliver disinfectant, which can disinfect the liquid outlet pipe 120 of the liquid outlet structure 100. The cabinet 1 of the liquid outlet machine includes a disinfectant storage barrel, which contains the disinfectant. One end of the second delivery pipe 3120 extends into the disinfectant storage barrel, and the other end is connected to the end of the cleaning pipeline 222 away from the cleaning branch pipe 231. In this way, the second delivery pipe 3120 can deliver the disinfectant in the disinfectant storage barrel to the cleaning pipeline 222, and then enter each group of liquid outlet structures 100 through the cleaning pipeline 222 and the cleaning branch pipe 231.

[0202] The second control valve 214 is disposed on the second delivery pipe 3120 and can control the opening and closing of the second delivery pipe 3120. When the second control valve 214 is open, disinfectant can enter the second delivery pipe 3120 and be delivered to the liquid outlet structure 100 via the cleaning pipe 222 and the cleaning branch pipe 231. When the second control valve 214 is closed, the second delivery pipe 3120 is disconnected, and disinfectant cannot enter the liquid outlet structure 100.

[0203] Furthermore, the second control valve 214 is electrically connected to the control mainboard 300, and is automatically opened or closed by the control mainboard 300. Optionally, the second control valve 214 is a solenoid valve. During cleaning, the control mainboard 300 controls the second control valve 214 to open. At this time, the disinfectant flows into the second delivery pipe 3120 and enters each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. As the disinfectant flows through the liquid outlet structure 100, it flushes the liquid outlet pipe 120, thereby disinfecting the liquid outlet structure 100.

[0204] In one embodiment, the cleaning tube group 210 also includes a third delivery tube 3120 and a third control valve 216. One end of the third delivery tube 3120 is connected to the descaling agent storage barrel of the liquid discharge machine, and the other end of the third delivery tube 3120 is connected to the cleaning tube 222. The third delivery tube 3120 is used to transport the descaling agent. The third control valve 216 is set on the third delivery tube 3120 to control the on and off of the third delivery tube 3120.

[0205] The third delivery pipe 3120 is used to deliver a descaling agent, which descales the liquid outlet pipe 120 of the liquid outlet structure 100. The liquid outlet cabinet 1 includes a descaling agent storage tank, which contains the descaling agent. One end of the third delivery pipe 3120 extends into the descaling agent storage tank, and the other end is connected to the end of the cleaning pipe 222 away from the cleaning branch pipe 231. In this way, the third delivery pipe 3120 can transport the descaling agent from the descaling agent storage tank to the cleaning pipe 222, and then enter each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231.

[0206] The third control valve 216 is disposed on the third delivery pipe 3120 and can control the opening and closing of the third delivery pipe 3120. When the third control valve 216 is open, the descaling agent can enter the third delivery pipe 3120 and be delivered to the liquid outlet structure 100 via the cleaning pipe 222 and the cleaning branch pipe 231. When the third control valve 216 is closed, the third delivery pipe 3120 is disconnected, and the descaling agent cannot enter the liquid outlet structure 100.

[0207] Furthermore, the third control valve 216 is electrically connected to the control mainboard 300, and is automatically opened or closed by the control mainboard 300. Optionally, the third control valve 216 is a solenoid valve. During cleaning, the control mainboard 300 controls the third control valve 216 to open. At this time, the descaling agent flows into the third delivery pipe 3120 and enters each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. After soaking in the liquid outlet pipe 120 for a certain period of time, the descaling agent can remove stains in the liquid outlet pipe 120, facilitating the thorough cleaning of the liquid outlet structure 100 later and ensuring a cleaning effect.

[0208] In one embodiment, the cleaning tube group 210 also includes a fourth delivery tube 3120 and a fourth control valve 218. One end of the fourth delivery tube 3120 is connected to the air inlet 402 of the liquid discharge machine, and the other end of the fourth delivery tube 3120 is connected to the cleaning tube 222. The fourth delivery tube 3120 is used to deliver air, and the fourth control valve 218 is set on the fourth delivery tube 3120 to control the on and off of the fourth delivery tube 3120.

[0209] The fourth delivery pipe 3120 is used to transport air. Cabinet 1 has an air inlet 402, which is connected to the external environment via a pipe. One end of the fourth delivery pipe 3120 is connected to the air inlet 402, and the other end is connected to the end of the cleaning pipeline 222 away from the cleaning branch pipe 231. In this way, the fourth delivery pipe 3120 can transport air to the cleaning pipeline 222, and then enter each group of liquid outlet structures 100 through the cleaning pipeline 222 and the cleaning branch pipe 231.

[0210] The fourth control valve 218 is disposed on the fourth delivery pipe 3120 and can control the opening and closing of the fourth delivery pipe 3120. When the fourth control valve 218 is open, air can enter the fourth delivery pipe 3120, thereby being delivered to the liquid outlet structure 100 through the purge pipe 222 and the purge branch pipe 231. When the fourth control valve 218 is closed, the fourth delivery pipe 3120 is disconnected, and air cannot enter the liquid outlet structure 100.

[0211] Furthermore, the fourth control valve 218 is electrically connected to the control mainboard 300 and is automatically opened or closed by the control mainboard 300. Optionally, the fourth control valve 218 is a solenoid valve. After tap water is introduced into the liquid outlet structure 100, the control mainboard 300 controls the fourth control valve 218 to open, allowing air to enter the fourth delivery pipe 3120 and then enter each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. As the air flows through the liquid outlet structure 100, it can empty the liquid outlet pipe 120.

[0212] That is, when air flows through the liquid outlet pipe 120, it can drive the tap water remaining on the inner wall of the liquid outlet pipe 120, thereby draining the tap water from the liquid outlet pipe 120 and leaving the inner wall of the liquid outlet pipe 120 clean. In this way, when the liquid outlet structure 100 outputs liquid materials, no residual tap water in the liquid outlet pipe 120 will come into contact with the liquid materials, thereby preventing contamination of the liquid materials and ensuring the taste of the prepared beverage.

[0213] In this embodiment, the cleaning structure 200 uses tap water, a descaling agent, disinfectant, and air to clean the liquid outlet structure 100. The first, second, third, and fourth delivery pipes 3120, 3120, and 3120 are arranged in parallel and connected to the end of the cleaning pipe 222 away from the cleaning branch pipe 231. A first control valve 212 is provided in the first delivery pipe 3120, a second control valve 214 is provided in the second delivery pipe 3120, a third control valve 216 is provided in the third delivery pipe 3120, and a fourth control valve 218 is provided in the fourth delivery pipe 3120.

[0214] Furthermore, the first control valve 212, the second control valve 214, the third control valve 216, and the fourth control valve 218 are all electrically connected to the control mainboard 300. The control mainboard 300 pre-stores the cleaning logic of the pipeline system. When the pipeline 222 system needs to be cleaned, the control mainboard 300 directly calls the pre-stored cleaning logic and controls the first control valve 212, the second control valve 214, the third control valve 216, and the fourth control valve 218 to perform corresponding actions according to the cleaning logic.

[0215] It is worth noting that in the pipeline system, the cleaning structure 200 can adopt different cleaning methods for each group of liquid outlet structures 100 according to the different working states of the liquid outlet machine, and can also be cleaned after the liquid outlet machine has been working for a period of time. Here, only the cleaning methods of the liquid outlet structure 100 before and after the liquid outlet machine is turned off and on are described.

[0216] The liquid dispensing machine needs to be shut down before closing (such as closing at night). In this case, the liquid dispensing structure 100 needs to be cleaned to remove the liquid material remaining in the liquid outlet pipe 120 to prevent the liquid material from deteriorating in the liquid outlet pipe 120 for a long time (such as overnight), thereby preventing bacteria from growing in the liquid outlet pipe 120 to ensure safety.

[0217] When the liquid outlet machine cleans the liquid outlet structure 100 before shutting down, tap water is first introduced into each liquid outlet structure 100 for a first preset time to clean each liquid outlet structure 100; then, a descaling agent is introduced into each liquid outlet structure 100 for a second preset time and soaked for a third preset time; after soaking, tap water is introduced into each liquid outlet structure 100 for a fourth preset time; and then, a disinfectant is introduced into each liquid outlet structure 100 for a fifth preset time.

[0218] The control board 300 controls the first control valve 212 to open, allowing the cleaning pump 221 to draw tap water into the first delivery pipe 3120. The water then flows through the cleaning pipe 222 and the cleaning branch pipe 231 and into each group of liquid outlet structures 100. The tap water then flushes the liquid outlet pipes 120 of each group of liquid outlet structures 100 for a first preset time to flush any residual liquid material. At this stage, each group of liquid outlet structures 100 can operate sequentially or in groups according to their serial numbers.

[0219] After flushing with tap water, the control board 300 controls the first control valve 212 to close and the third control valve 216 to open. The cleaning pump 221 then draws the descaling agent into the third delivery pipe 3120, which then enters each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. The descaling agent is then introduced into each group of liquid outlet structures 100 for a second preset time, ensuring that each group of liquid outlet structures 100 is fully filled with the descaling agent. At this stage, each group of liquid outlet structures 100 can operate sequentially or in groups according to their sequence number.

[0220] The control board 300 then controls the third control valve 216 to close, and the cleaning pump 221 to shut down. At this point, all pumps in the piping system are deactivated. The descaling agent soaks in the liquid outlet structure 100 to remove dirt from the liquid outlet pipe 120. After the descaling agent has soaked in the liquid outlet pipe 120 for a third preset time, the control structure controls the first control valve 212 to open, allowing the cleaning pump 221 to draw tap water to flush the liquid outlet pipe 120 of each group of liquid outlet structures 100 for a fourth preset time to remove the descaling agent from each liquid outlet pipe 120. At this stage, each group of liquid outlet structures 100 can operate sequentially according to their sequence number.

[0221] After the descaling agent is flushed with tap water, the control board 300 controls the first control valve 212 to close and the second control valve 214 to open. At this point, the cleaning pump 221 can draw disinfectant into the second delivery pipe 3120, which then enters each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. Disinfectant is then introduced into each group of liquid outlet structures 100 for a fifth preset time, ensuring that the liquid outlet pipes 120 of each liquid outlet structure 100 are fully filled with disinfectant. At this stage, each group of liquid outlet structures 100 can operate sequentially or in groups according to their serial number.

[0222] This completes the cleaning of the liquid outlet structure 100 before shutting down the liquid dispenser. After cleaning, disinfectant remains in the liquid outlet pipe 120, disinfecting it and preventing bacteria from growing in the pipe 120 when it is left idle for extended periods. The liquid dispenser needs to be turned on before opening (or opening early). Since disinfectant is present in the liquid outlet pipe 120, it must be drained from the pipe 120 after it is turned on.

[0223] After the liquid discharge machine is turned on, the disinfectant in the liquid discharge pipe 120 needs to be discharged. At this time, tap water is introduced into each liquid discharge structure 100 for a sixth preset time; and air is introduced into each liquid discharge structure 100 for a seventh preset time.

[0224] The control board 300 controls the first control valve 212 to open, allowing the cleaning pump 221 to draw tap water into the first delivery pipe 3120. The water then flows through the cleaning pipe 222 and the cleaning branch pipe 231 and into each set of liquid outlet structures 100. The tap water then flushes the liquid outlet pipes 120 of each set of liquid outlet structures 100 for a sixth preset time to flush any residual disinfectant from the liquid outlet pipes 120. At this stage, each set of liquid outlet structures 100 can operate sequentially according to their sequence number.

[0225] After the tap water flushing is complete, the control board 300 controls the first control valve 212 to close and the fourth control valve 218 to open. The cleaning pump 221 draws air into the fourth delivery pipe 3120, which then enters each set of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. After the seventh preset time, the air removes the tap water remaining on the inner wall of the liquid outlet pipe 120 in each set of liquid outlet structures 100, thereby emptying the liquid outlet pipe 120. In this way, the liquid dispenser completes the cleaning of the liquid outlet structure 100, and the liquid outlet structure 100 can be used to prepare beverages.

[0226] In this embodiment, the number of liquid outlet structures 100 is ten, and the corresponding preset times are: the first preset time is 30 seconds, the second preset time is 12 seconds, the third preset time is 600 seconds, the fourth preset time is 30 seconds, the fifth preset time is 15 seconds, the sixth preset time is 60 seconds, and the seventh preset time is 10 seconds. Of course, in other embodiments of the present application, the preset times can also be other, and the cleaning process is substantially the same as in the above embodiment, and will not be repeated here.

[0227] It should be noted that the cleaning of the liquid outlet structure 100 in the above embodiment is only one cleaning method, but the cleaning of the liquid outlet structure 100 is not limited to the above embodiment. The order and time of introducing tap water, descaling agent, disinfectant and air into the liquid outlet structure 100 during cleaning can be different. The operator can adjust it according to needs, which will not be repeated here.

[0228] Of course, in this application, the cleaning structure 200 can also be cleaned with other types of cleaning fluids, as long as a delivery pipe 3120 and a control valve are used to deliver the corresponding cleaning fluid. Moreover, the cleaning structure 200 can also be cleaned with more cleaning steps, as long as corresponding delivery pipes 3120 and control valves are added and the cleaning steps are adjusted.

[0229] In one embodiment, the cleaning structure 200 further includes a drainage mesh 240 and a drainage container. The drainage mesh 240 is arranged below the liquid outlet port 501. One end of the drainage container is connected to the drainage mesh 240, and the other end is connected to the sewer pipe outlet 404 of the liquid discharge machine.

[0230] Cabinet 1 has a drain outlet 404, which is connected to an external drain outlet via a pipe. Drain mesh 240 is hollowed out, with the bottom of the mesh 240 connected to the top of a drainage container, which in turn is connected to drain outlet 404. It's worth noting that the type of drainage container is generally not limited, as long as it can discharge cleaning fluid through drain outlet 404.

[0231] After the cleaning liquid is discharged from the liquid outlet port 501, it can fall on the drainage mesh plate 240. Then, the cleaning liquid can enter the drainage container through the drainage mesh plate 240. The cleaning liquid in the drainage container can be discharged through the drain pipe outlet 404. In addition, when making a drink, if the liquid material overflows into the cup, the overflowing liquid material can also be discharged through the drainage mesh plate 240.

[0232] The piping system of the present application uses a cleaning pipe 222 to automatically clean each group of liquid outlet structures 100. During cleaning, the cleaning pump 221 transports the cleaning liquid transported by the cleaning pipe group 210 to each cleaning branch pipe 231, and enters the corresponding liquid outlet structure 100 through the cleaning branch pipe 231, thereby cleaning each group of liquid outlet structures 100 and preventing residual liquid materials in the liquid outlet structure 100. At the same time, when the cleaning pump 221 is working, it can put the cleaning pipe 222, the cleaning branch pipe 231 and the liquid outlet structure 100 in a positive pressure state, and ensure that the cleaning liquid can flow stably in the cleaning pipe 222, the cleaning branch pipe 231 and the liquid outlet structure 100, preventing air leakage, achieving thorough cleaning, and ensuring the cleaning effect. Moreover, the structure of the piping system is simple, which is easy to apply to the liquid outlet machine, simplifying the cleaning process of the liquid outlet machine and facilitating the cleaning operation.

[0233] The liquid dispensing head includes a main body 100a, a liquid dispenser 200a, and a weighing device 300a. The main body 100a includes a head body 110a and a body body 120a. The head body 110a is disposed on the body body 120a, the liquid dispenser 200a is disposed on the head body 110a, and the weighing device 300a is disposed on the body body 120a. The weighing device 300a is located directly below the liquid dispenser 200a. The term "directly below" indicates that the relative positional relationship between the weighing device 300a and the liquid dispenser 200a is a relative position of up and down in the direction of gravity. This indicates that the weighing device 300a is located directly below the liquid dispenser 200a, so that after the liquid is dispensed, the liquid dispenser 200a can cause the beverage to fall along the direction of gravity and fall directly onto the weighing device 300a. At this time, the disposable drinking cup can be placed on the weighing device 300a, and the weighing device 300a is used as a reference for the placement position of the disposable drinking cup to initially locate the relative positions of the disposable drinking cup and the liquid dispenser 200a in the direction of gravity.

[0234] The weighing device 300a includes a cantilever element 310a, a weighing platform element 320a and a positioning element 330a. One end of the cantilever element 310a is connected to the main body 120a of the fuselage, and the weighing platform element 320a is connected to the other end of the cantilever element 310a. The length of the cantilever element 310a can be adjusted so that the weighing platform element 320a located at its other end can be opposite to the liquid dispenser 200a in the direction of gravity. The weighing platform element 320a has a load-bearing surface 321a, and the load-bearing surface 321a faces the liquid dispenser 200a. The disposable drinking cup can be placed on the weighing surface of the weighing platform element 320a, thereby enabling the disposable drinking cup to be further accurately aligned with the liquid dispenser 200a in the upper and lower directions.

[0235] Furthermore, a positioning element 330a is disposed on the weighing platform 320a. The positioning element 330a is used to define a liquid drop area 322a on the load-bearing surface 321a of the weighing platform 320a. The liquid drop area 322a is aligned with the liquid dispenser 200a in the direction of gravity. At this point, an operator can place a disposable drinking cup on the weighing platform 320a of the weighing device 300a and position it in the liquid drop area 322a using the positioning element 330a. After adjusting the length of the cantilever element 310a and the positioning of the positioning element 330a, the liquid drop area 322a is more accurately aligned with the liquid dispenser 200a in the direction of gravity.

[0236] As can be seen, in the above structure, the weighing device 300a is first used as a reference for the placement of the disposable drinking cup, initially determining the vertical relative position of the disposable drinking cup and the liquid dispenser 200a in the direction of gravity. Furthermore, by adjusting the length of the cantilever element 310a, the weighing platform element 320a is aligned more precisely with the liquid dispenser 200a in the direction of gravity, enabling the disposable drinking cup to achieve further precise vertical alignment with the liquid dispenser 200a. Finally, the positioning element 330a forms a drop area 322a on the weighing platform element 320a, allowing the disposable drinking cup to be precisely positioned relative to the liquid dispenser 200a in the direction of gravity. Furthermore, the positioning element 330a allows the operator to quickly position the disposable drinking cup in the drop area 322a, ensuring precise vertical alignment with the liquid dispenser 200a while also increasing the speed of positioning and placement, thereby increasing the speed of dispensing.

[0237] The positioning element 330a can adopt various structures. For example, in one embodiment, the positioning element 330a includes at least two positioning stops 3310. For example, the positioning stops 3310 can be provided in two, three, or more numbers. At least two positioning stops 3310 are provided on the load-bearing surface 321a of the weighing platform element 320a. Each positioning stop 3310 has a limiting surface 3320. Therefore, the multiple positioning stops 3310 can cooperate with each other, and the limiting surfaces 3320 of different positioning stops 3310 can limit contact with different positions of the beverage cup, thereby positioning the beverage cup in the liquid drop area 322a of the weighing platform element 320a.

[0238] In one embodiment, the cantilever element 310a is a linear plate, the weighing platform element 320a is a circular plate, the thickness of the cantilever element 310a is the same as the thickness of the weighing platform element 320a, the end of the cantilever element 310a is connected to the side of the weighing platform element 320a, and the cantilever element 310a and the weighing platform element 320a are configured as an integrally molded structure. The positioning element 330a includes two positioning stops 3310, which are plate-shaped parts. One end of the two positioning stops 3310 is connected, and the other ends of the two positioning stops 3310 are separated. There is an angle between the two positioning stops 3310, thereby constructing a triangular limiting structure on the weighing platform element 320a through the two positioning stops 3310. The inner surface of each positioning stop 3310 is used to constitute a limiting surface 3320. The two positioning stops 3310 are vertically arranged on the load-bearing surface 321a of the weighing platform element 320a, and surround the liquid falling area 322a of the weighing platform element 320a.

[0239] In addition, the liquid drop area 322a of the scale base 320a includes a plurality of liquid leakage holes 3230. These holes 3230 are constructed in a circular pattern. When liquid is spilled from the liquid dispenser 200a onto the outside of the disposable drinking cup, the holes 3230 can be used to drain the overflowed liquid, preventing it from remaining on the scale 300a. Furthermore, one end of the cantilever element 310a is detachably connected to the main body 120a, allowing the scale 300a to be removed from the main body 120a. This facilitates routine cleaning of the cantilever element 310a, scale base 320a, and positioning element 330a, ensuring food safety.

[0240] In addition to mechanical structures such as the cantilever element 310a, the weighing platform element 320a, and the positioning element 330a, the weighing scale 300a also includes an electrical device capable of calculating flow rate. For example, in one embodiment, the weighing scale 300a includes a flow rate calculation unit, which is disposed in the main body 100a. The flow rate calculation unit calculates the total amount of liquid discharged from the liquid dispenser 200a using weight data and time data. For example, the flow rate calculation unit is connected to the cantilever element 310a and the liquid dispenser 200a. The flow rate calculation unit is used to obtain weight data borne by the cantilever element 310a and time data of liquid discharge from the liquid dispenser 200a. The weight data represents the weight data borne by the disposable drinking cup after receiving all the liquid discharged from the liquid dispenser 200a after the weight of the disposable drinking cup is removed. When the time data of liquid discharge from the liquid dispenser 200a is also obtained, the flow rate calculation unit can calculate the flow rate of the fluid discharged from the liquid dispenser 200a based on the weight data and time data.

[0241] The specific calculation formula is: fluid flow rate = weight data / time data x water density. It should be noted that the fluid flow rate is temporarily estimated based on the density of water, so there is a certain degree of error in the fluid flow rate.

[0242] In one embodiment, the flow rate calculation unit includes a weight detection device, a time measurement device, and a data calculation device. The weight detection device is disposed within a body cavity of the body 120a. The body 120a defines an assembly hole, through which one end of the cantilever element 310a is assembled within the body cavity of the body 120a. The weight detection device is connected to the cantilever element 310a within the body cavity of the body 120a to obtain weight data borne by the cantilever element 310a.

[0243] A time measurement device is disposed within the head chamber of the handpiece body 110a and is connected to the liquid dispenser 200a. The time measurement device is used to obtain time data for the liquid dispenser 200a during the liquid dispense process. The time data represents the duration from the start of liquid dispense to the end of liquid dispense. A data calculation device is disposed within the body chamber of the main body 120a and is connected to the weight detection device and the time measurement device. The data calculation device is used to obtain weight data and time data, and to calculate the flow rate of the fluid dispensed by the liquid dispenser 200a based on the weight and time data.

[0244] When using the aforementioned time measurement device to obtain time data and calculate fluid flow rate, one approach involves first issuing a fixed-time liquid discharge instruction and then obtaining the weight of the discharged liquid within that fixed time. The formula for calculating fluid flow rate is: fluid flow rate = weight data / time data x water density. In this case, the time data represents the specified fixed time, and the weight data represents the weight of the liquid discharged within that fixed time.

[0245] Alternatively, multiple liquid discharge instructions can be issued at different fixed times, and then the weight data of the discharged liquid can be obtained at each fixed time. In this case, the weight data at each fixed time can be weighed to calculate the different fluid flow rates at each fixed time, ensuring accurate discharge of the liquid volume at each fixed time. In this method, the formula for calculating the fluid flow rate is also: fluid flow rate = weight data / time data x water density. In this case, the time data represents each different fixed time issued, and the weight data also represents the weight data of the liquid volume discharged at each different fixed time.

[0246] In short, the time data can be a fixed time or different fixed times, and the weight data can be the weight data obtained at each fixed time. Those skilled in the art can select an appropriate calculation method according to actual needs, and this is not limited here.

[0247] After extensive analysis and research, those skilled in the art have discovered that inaccurate material suction volume can be caused by material blockage or obstruction during material delivery. This blockage is primarily caused by the connection between the fluid delivery tube 3120 and the fluid outlet tubes 120 on the discharge head.

[0248] Since several different types of materials need to be concentratedly transported to the liquid discharge head and flow out through different fluid outlet pipes 120 on the liquid discharge head, in order to ensure that several materials flowing out of the several fluid outlet pipes 120 can be directly introduced into the milk tea cup at one time, the several fluid outlet pipes 120 need to maintain a certain degree of concentration, at least the coverage area of ​​all the fluid outlet pipes 120 on the liquid discharge head cannot exceed the cup mouth area of ​​the milk tea cup.

[0249] The fluid outlet pipe 120 can be designed with a smaller diameter and distributed as close together as possible on the discharge head. However, the fluid delivery pipe 3120 needs to connect to other material barrels, so the diameter of the fluid delivery pipe 3120 is generally larger than the diameter of the fluid outlet pipe 120. The larger diameter fluid outlet pipe 120 connects to several material barrels at various locations throughout the discharge machine and then simultaneously leads to the discharge head. When assembled with the multiple fluid outlet pipes 120 through a bundled assembly, some fluid delivery pipes 3120 may experience significant distortion near the fluid outlet pipe 120. Different fluid delivery pipes 3120 extending from different locations to the discharge head also experience varying distortion angles. Excessive distortion reduces the internal space within the fluid delivery pipe 3120 at the distorted location, causing blockage and obstruction. For more viscous materials like syrups, the increased viscosity and reduced internal space make the blockage and obstruction more pronounced.

[0250] The amount of syrup affects the sweetness of a drink. Inaccurate amounts can cause variations in the sweetness of a drink, a factor that consumers value most, and therefore requires urgent attention. Furthermore, other flavoring ingredients, such as syrup, can affect the taste of a drink and ultimately influence the customer's experience.

[0251] To address the above technical issues, the present application provides a liquid dispenser 200a, comprising a device assembly housing 210a and a fluid outlet assembly 220a. Device assembly housing 210a defines an internal cavity 211a, a chamber window for the internal cavity 211a is defined at the top of device assembly housing 210a, and a plurality of fluid assembly holes 212a are defined at the bottom of device assembly housing 210a. Device assembly housing 210a can adopt various regular or irregular shapes, such as cylindrical, elliptical, or square, and is not limited herein.

[0252] In one embodiment, the device assembly shell 210a may include a shell side wall plate and a shell bottom wall plate, the shell side wall plate is a cylindrical plate body, the interior of the shell side wall plate has an axially through inner cavity, the shell bottom wall plate is sealed and assembled at the end of the shell side wall plate, the shell side wall plate and the shell bottom wall plate together enclose the inner cavity space 211a of the device assembly shell 210a, and a number of fluid assembly holes 212a are opened on the shell bottom wall plate.

[0253] The fluid outlet assembly 220a includes several fluid outlet tubes 120, each of which is disposed within a fluid assembly hole 212a. Each fluid outlet tube 120 comprises a connected middle tube section 211b, an inner tube section 212b, and an outer tube section 213b. The inner tube section 212b and the outer tube section 213b are located at opposite ends of the middle tube section 211b. The middle tube section 211b, the inner tube section 212b, and the outer tube section 213b of the fluid outlet tube 120 are axially separated into different tube sections within the fluid outlet tube 120. The middle tube section 211b, the inner tube section 212b, and the outer tube section 213b of the fluid outlet tube 120 form an integrally formed tube structure. In addition, the middle tube body 211b, inner tube body 212b and outer tube body 213b of the fluid outlet tube 120 can also be separate tube bodies, which are connected to form a complete fluid outlet tube 120. Those skilled in the art can design it according to actual needs and no limitation is made here.

[0254] Based on the distinction between the middle tube body 211b, the inner tube body 212b and the outer tube body 213b in the fluid outlet tube 120, the middle tube body 211b of each fluid outlet tube 120 can be located in a matching fluid assembly hole 212a, the inner tube body 212b of each fluid outlet tube 120 can be located in the inner cavity space 211a, and the outer tube body 213b of each fluid outlet tube 120 can be located outside the inner cavity space 211a.

[0255] In this assembly structure, the inner section tube body 212b of each fluid outlet tube 120 is the tube section portion in the inner cavity space 211a for connecting to the fluid delivery tube 3120. Therefore, among the inner section tube bodies 212b of several fluid outlet tubes 120, at least a part or all of the inner section tube bodies 212b of the fluid outlet tubes 120 can be designed as curved tube bodies. Based on the design of the curved tube bodies, the inner section tube bodies 212b of several fluid outlet tubes 120 can be distributed in a more dispersed state in the inner cavity space 211a compared to the outer section tube bodies 213b.

[0256] The inner sections 212b of the fluid outlet pipes 120 are based on a more dispersed distribution state. When the fluid delivery pipes 3120 are connected to the fluid outlet pipes 120 in the inner cavity space 211a, the fluid delivery pipes 3120 can also be distributed in a more dispersed state in the inner cavity space 211a. In this way, the looseness of the fluid delivery pipes 3120 in the inner cavity space 211a is improved. The more dispersed distribution state can avoid the adjacent fluid delivery pipes 3120 from squeezing each other in the inner cavity space 211a, and thus avoid deformation caused by mutual squeezing, thereby enabling the fluid delivery pipes 3120 to transport materials in a normal internal space, avoiding the situation where the material is not smooth or blocked at the deformed position of the fluid delivery pipe 3120.

[0257] In one embodiment, at least a portion or all of the outer tube section 213b of the fluid outlet pipe 120 can also be designed as a curved tube. In this case, the inner tube section 212b of the fluid outlet pipe 120 can be designed as a curved tube that makes the inner tube sections 212b more dispersed, while the outer tube section 213b of the fluid outlet pipe 120 can be designed as a curved tube that makes the outer tube sections 213b more densely packed, such as by curving toward the center. As a result, the density (or looseness) between the outer tube sections 213b and the inner tube sections 212b can be significantly different. When the outer tube sections 213b of the fluid outlet tubes 120 are densely packed with the mouth of the milk tea cup due to the curved tube design, the inner tube sections 212b of the fluid outlet tubes 120 will be more dispersed relative to the outer tube sections 213b, thereby further increasing the looseness of the fluid delivery tubes 3120 in the inner cavity space 211a and further avoiding mutual squeezing of adjacent fluid delivery tubes 3120 in the inner cavity space 211a.
