[0038] As you can understand, current commercial beverage dispensers typically include an operating table, a liquid outlet pipe, and a cabinet. The liquid outlet pipe is installed in the cabinet and can draw liquid materials from the refrigerated container in the cabinet and output them through the liquid outlet port. After the commercial beverage dispenser is turned on or off, liquid materials are easily retained in the liquid outlet pipe, requiring regular cleaning of the liquid outlet pipe. However, the cleaning process of current commercial beverage dispensers is complex, and pipe leaks are prone to incomplete cleaning, which affects the cleaning effect.

[0039] For this, see Figures 1 to 4 , the present application provides a pipeline system 10. Figure 1 This is a three-dimensional diagram of a liquid dispensing machine 1 according to an embodiment of the present application. Figure 2 for Figure 1 The front view of the liquid dispensing machine 1 shown, Figure 3 for Figure 1 The schematic diagram of the liquid dispensing machine 1 without the cover and the cabinet door is shown. Figure 4 for Figure 3 The figure shows a schematic diagram of the piping system 10 in the liquid dispensing machine 1. The piping system 10 is used in the liquid dispensing machine 1 and is installed in the cabinet 40 of the liquid dispensing machine 1. The liquid dispensing machine 1 can output liquid materials to prepare liquid beverages or liquid-solid mixed beverages. Of course, in other embodiments of the present application, the piping system 10 can also be used in other liquid conveying equipment.

[0040] The piping system 10 can deliver liquid materials and automatically clean the liquid outlet structure 100, thereby preventing residual liquid materials from remaining in the liquid outlet structure 100. Furthermore, during cleaning, the piping system 10 is in a positive pressure state, ensuring that the cleaning liquid flows stably therein, preventing air leakage, achieving thorough cleaning, and ensuring a cleaning effect. Furthermore, the piping system 10 has a simple structure and is easily applicable to the liquid outlet machine 1, simplifying the cleaning process of the liquid outlet machine 1 and facilitating the cleaning operation.

[0041] This application will only illustrate the application of the piping system 10 in a liquid dispenser 1. To better illustrate the structure of the piping system 10, a brief description of the structure of the liquid dispenser 1 is provided here. The liquid dispenser 1 includes an operating table 50, a cabinet 40, and the piping system 10 described herein. The operating table 50 is mounted within the cabinet 40, and the piping system 10 is housed within the cabinet 40. The cabinet 40 is the main structure of the liquid dispenser 1, and the operating table 50 is the operating component of the liquid dispenser 1. The operator manipulates the operating table 50 to control the liquid dispensing of the liquid dispenser 1 and prepare the corresponding beverage.

[0042] The operating table 50 has a liquid outlet port 501, which is connected to the piping system 10. The cabinet 40 can store a liquid storage container 60, which contains liquid materials. The piping system 10 can draw liquid materials from the liquid storage container 60 to the liquid outlet port 501 and output the liquid materials through the liquid outlet port 501. When cleaning is required, the piping system 10 can be flushed to prevent residual liquid materials in the piping system 10.

[0043] It is worth noting that the liquid storage container 60 is divided into a refrigerated container 601 and a liquid storage barrel 602. The refrigerated container 601 is stored in the refrigerated chamber 401 of the cabinet 40. The refrigerated chamber 401 refrigerates the liquid material in the refrigerated container 601 to prevent the liquid material in the refrigerated container 601 from deteriorating. The liquid storage barrel 602 is arranged on the top of the cabinet 40 and can store liquid materials that do not require refrigeration.

[0044] It is understood that there can be multiple refrigerated containers 601 and multiple liquid storage barrels 602. Multiple refrigerated containers 601 and multiple liquid storage barrels 602 can store different types of liquid materials, thereby increasing the variety of beverages that can be prepared by the liquid dispenser 1. Moreover, the control pipeline system 10 can be used to extract the liquid material from the corresponding liquid storage container 60 according to the type of beverage to be prepared. The specific type of liquid material stored in the refrigerated container 601 and the liquid storage barrel 602 is not explained here.

[0045] The specific structure of the pipeline system 10 in one embodiment is described below.

[0046] See also Figures 1 to 4In one embodiment, the piping system 10 includes multiple groups of liquid outlet structures 100 and cleaning structures 200. The multiple groups of liquid outlet structures 100 are arranged in parallel, and the inlet end of each group of liquid outlet structures 100 is respectively connected to each liquid storage container 60 in the liquid outlet machine 1, and the outlet end of each group of liquid outlet structures 100 is connected to the liquid outlet port 501 of the liquid outlet machine 1. The cleaning structure 200 includes a cleaning pipe group 210, a cleaning assembly 220, and a cleaning pipe group 230. The cleaning assembly 220 includes a cleaning pipe 222 and a cleaning pump 221. The cleaning pipe 222 is used to transport cleaning liquid. The cleaning pump 221 is arranged in the cleaning pipe 222. The cleaning pipe 222 includes multiple cleaning branches 231 arranged in parallel. The cleaning pipe group 210 is connected to one end of the cleaning assembly 220 to transport cleaning liquid to the cleaning assembly 220. One end of each cleaning branch 231 is connected to the other end of the cleaning pipe 222, and the other end is respectively connected to the inlet end of the liquid outlet structure 100.

[0047] The liquid outlet structure 100 is a component for extracting liquid material. It has an inlet end and an outlet end. The inlet end of the liquid outlet structure 100 is the end where the liquid material enters, and the outlet end of the liquid outlet structure 100 is the port where the liquid material is discharged. The inlet end of the liquid outlet structure 100 is connected to the liquid storage container 60, and the outlet end of the liquid outlet structure 100 is connected to the liquid outlet port 501.

[0048] The liquid dispenser 1 controls the liquid outlet structure 100 to extract liquid material from the liquid storage container 60 and delivers the liquid material to a container, such as a cup, through the liquid outlet port 501 via the liquid outlet structure 100, thereby producing a drink. Furthermore, the liquid outlet structure 100 is disposed within the cabinet 40, which conceals the various pipes of the liquid outlet structure 100, preventing them from being exposed and ensuring safe liquid material delivery.

[0049] Multiple groups of liquid outlet structures 100 are arranged in parallel within the ingredient cabinet of cabinet 40. The inlet of each group of liquid outlet structures 100 is connected to a respective liquid storage container 60, and the outlet of each group of liquid outlet structures 100 is connected to the liquid outlet port 501. This allows each liquid storage container 60 to deliver liquid material through its corresponding liquid outlet structure 100, preventing mixing of liquid materials and ensuring a consistent drink's flavor.

[0050] After the liquid outlet structure 100 delivers liquid material, residual liquid material may remain in the liquid outlet structure 100. If the liquid outlet machine 1 is closed, the residual liquid material in the liquid outlet structure 100 may deteriorate, necessitating cleaning of the liquid outlet structure 100. The present application also includes a cleaning structure 200 in the cabinet 40. The cleaning structure 200 is connected to the inlet end of each group of liquid outlet structures 100 and can clean each group of liquid outlet structures 100 to remove residual liquid material and ensure effective cleaning.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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 10 (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 10, preventing air leaks and air ingress, ensuring thorough cleaning of the liquid outlet structures 100 and ensuring effective cleaning. Furthermore, the piping system 10 has a simple structure, facilitating cleaning operations.

[0055] 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.

[0056] 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.

[0057] The piping system 10 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 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 10 has a simple structure, which is convenient for application to the liquid outlet machine 1, simplifying the cleaning process of the liquid outlet machine 1 and facilitating the cleaning operation.

[0058] See also Figures 1 to 4 For example, there are ten groups of liquid outlet structures 100, and ten liquid storage containers 60, including six refrigerated containers 601 and four liquid storage barrels 602. Six of the liquid outlet structures 100 are connected to the refrigerated containers 601, and four of the liquid outlet structures 100 are connected to the liquid storage barrels 602. Of course, in other embodiments of the present application, the number of liquid outlet structures 100 can be other, and the number of refrigerated containers 601 and liquid storage barrels 602 can also be adjusted.

[0059] It is worth noting that the principle of the liquid outlet structure 100 transporting liquid materials in the refrigerated container 601 is essentially the same as the principle of transporting liquid materials in the liquid storage barrel 602. In this application, only the liquid outlet structure 100 transporting liquid materials in the liquid storage container 60 is used as an example for description. Moreover, which liquid outlet structure 100 is connected to the refrigerated container 601 and which liquid outlet structure 100 is connected to the liquid storage barrel 602 will not be repeated.

[0060] See also Figures 2 to 4 In one embodiment, each group of liquid outlet structures 100 includes a power component 110 and a liquid outlet pipe 120. The power component 110 is arranged on the liquid outlet pipe 120. One end of the liquid outlet pipe 120 is respectively connected to each liquid storage container 60 in the liquid outlet machine 1, and the other end of each group of liquid outlet structures 100 is connected to the liquid outlet port 501 of the liquid outlet machine 1.

[0061] 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 opposite each other. The inlet end of the liquid outlet pipe 120 is connected to the liquid storage container 60, 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.

[0062] When making beverages, the liquid dispensing machine 1 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 60 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.

[0063] See also Figure 2 In one embodiment, the piping system 10 further includes a control motherboard 300, which is disposed on the back of the cabinet 40 and electrically connected to the power assembly 110 in each group of liquid discharge structures 100. In other words, the control motherboard 300 serves as the main control board of the liquid discharge machine 1, and intelligent liquid discharge control of the liquid discharge machine 1 is implemented through the control motherboard 300. Optionally, the control motherboard 300 is a PCB.

[0064] When the liquid dispensing machine 1 receives the order information, it can send a control signal based on the order information to the control board 300. After receiving the control signal, the control board 300 can analyze the order information and generate liquid dispensing information for the liquid dispensing machine 1. The control board 300 can then send the liquid dispensing 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 dispensing pipe 120.

[0065] Furthermore, after receiving the liquid discharge information, the power assembly 110 discharges liquid according to the time set by the liquid discharge information, such as the time after which the power assembly 110 is activated to aspirate 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 1.

[0066] See also Figures 2 to 5 In one embodiment, the power assembly 110 includes a peristaltic pump 111, which is disposed on the liquid outlet pipe 120. The peristaltic pump 111 is electrically connected to the control motherboard 300. When the peristaltic pump 111 is working, the liquid outlet pipe 120 can suck the liquid material in the liquid storage container 60. Figure 5 for Figure 4 The diagram shows multiple groups of liquid outlet structures 100 in the piping system 10. In the piping system 10 of the present application, the liquid material is transported by the peristaltic pump 111, and each group of liquid outlet structures 100 is cleaned by the cooperation of the peristaltic pump 111 and the cleaning pump 221.

[0067] 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.

[0068] See also Figures 2 to 5 In one embodiment, the power assembly 110 further includes a buffer 112, which is disposed on the liquid outlet pipe 120 and located at the outlet end of the peristaltic pump 111. The buffer 112 has a certain elasticity and can play a buffering role. The buffer 112 can change in volume according to changes in water pressure, thereby forming a buffering effect.

[0069] When the liquid outlet pipe 120 conveys liquid materials, the buffering effect of the buffer member 112 can buffer the conveying speed of the liquid material, avoid excessive conveying of the liquid material, and make the liquid material flow slowly and steadily in the liquid outlet pipe 120 to avoid splashing of the liquid material.

[0070] 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.

[0071] 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.

[0072] In one embodiment, the liquid outlet pipe 120 is a hose. This facilitates the routing of the liquid outlet pipe 120 within the cabinet 40. Of course, in the piping system 10 of the present application, each pipe is a hose. In other words, the cleaning pipe 222 and the cleaning branch pipe 231 are all hoses.

[0073] 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, so that the entire pipeline system 10 is under positive pressure to prevent air leakage.

[0074] Understandably, due to the poor pumping power of the peristaltic pump 111, it is easy to fail to pump the cleaning liquid of the descaling agent, and it is easy to draw air into the pipeline from the leak point. After the cleaning pump 221 is set in the cleaning pipeline 222 of the present application, the cleaning pump 221 can provide a greater driving force of active driving, so that the descaling agent can actively and smoothly flow in the liquid outlet structure 100, generate positive pressure, and avoid air leakage.

[0075] 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.

[0076] In one embodiment, the cleaning structure 200 further includes a pressure reducing valve, which is disposed on the cleaning pipeline 222 or the cleaning branch pipe 231. The pressure reducing valve can reduce the water pressure in the piping system 10, preventing the cleaning pipeline 222 or the cleaning branch pipe 231 from bursting due to excessive water pressure, thereby ensuring safety.

[0077] See also Figures 4 to 6 In one embodiment, the cleaning pipe assembly 230 further includes a cleaning main pipe 232 , one end of which is connected to the cleaning pipeline 222 , and the cleaning main pipe 232 is connected to each cleaning branch pipe 231 . Figure 6 for Figure 4 A schematic diagram of the cleaning structure 200 in the piping system 10 is shown.

[0078] 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.

[0079] 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 .

[0080] See also Figures 1 to 4 、 Figure 6 In one embodiment, the cleaning pipe group 210 includes a first delivery pipe 211 and a first control valve 212. One end of the first delivery pipe 211 is connected to the tap water inlet 403 of the liquid discharge machine 1, and the other end of the first delivery pipe 211 is connected to the cleaning pipe 222. The first delivery pipe 211 is used to deliver tap water. The first control valve 212 is set in the first delivery pipe 211 to control the on and off of the first delivery pipe 211.

[0081] The first delivery pipeline 211 is used to deliver tap water. The cabinet 40 has a tap water inlet 403, which is connected to an external tap water source via a pipe. One end of the first delivery pipeline 211 is connected to the tap water inlet 403, 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 first delivery pipeline 211 can deliver tap water 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.

[0082] A first control valve 212 is disposed in the first delivery pipeline 211 and can control the opening and closing of the first delivery pipeline 211. When the first control valve 212 is open, tap water can enter the first delivery pipeline 211 and be delivered to the liquid outlet structure 100 via the cleaning pipeline 222 and the cleaning branch pipe 231. When the first control valve 212 is closed, the first delivery pipeline 211 is disconnected, and tap water cannot enter the liquid outlet structure 100.

[0083] 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 pipeline 211 and enters each group of liquid outlet structures 100 through the cleaning pipeline 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.

[0084] See also Figures 1 to 4 、 Figure 6 In one embodiment, the cleaning pipe group 210 also includes a second delivery pipeline 213 and a second control valve 214. One end of the second delivery pipeline 213 is connected to the disinfectant storage barrel of the liquid discharge machine 1, and the other end of the second delivery pipeline 213 is connected to the cleaning pipeline 222. The second delivery pipeline 213 is used to deliver disinfectant. The second control valve 214 is set in the second delivery pipeline 213 to control the on and off of the second delivery pipeline 213.

[0085] The second delivery pipeline 213 is used to deliver disinfectant, which can disinfect the liquid outlet pipe 120 of the liquid outlet structure 100. The cabinet 40 of the liquid outlet machine 1 includes a disinfectant storage barrel, which stores the disinfectant. One end of the second delivery pipeline 213 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 231. In this way, the second delivery pipeline 213 can transport the disinfectant from 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 231.

[0086] A second control valve 214 is disposed in the second delivery pipeline 213 and can control the opening and closing of the second delivery pipeline 213. When the second control valve 214 is open, disinfectant can enter the second delivery pipeline 213 and be delivered to the liquid outlet structure 100 via the cleaning pipeline 222 and the cleaning branch pipe 231. When the second control valve 214 is closed, the second delivery pipeline 213 is disconnected, and disinfectant cannot enter the liquid outlet structure 100.

[0087] 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 pipeline 213 and enters each group of liquid outlet structures 100 through the cleaning pipeline 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.

[0088] See also Figures 1 to 4 、 Figure 6 In one embodiment, the cleaning tube group 210 also includes a third delivery pipeline 215 and a third control valve 216. One end of the third delivery pipeline 215 is connected to the descaling agent storage barrel of the liquid discharge machine 1, and the other end of the third delivery pipeline 215 is connected to the cleaning pipeline 222. The third delivery pipeline 215 is used to deliver the descaling agent. The third control valve 216 is set in the third delivery pipeline 215 to control the on and off of the third delivery pipeline 215.

[0089] The third delivery line 215 is used to deliver a descaling agent, which can descale the liquid outlet pipe 120 of the liquid outlet structure 100. The cabinet 40 of the liquid outlet machine 1 includes a descaling agent storage barrel, which contains the descaling agent. One end of the third delivery line 215 extends into the descaling agent storage barrel, and the other end is connected to the end of the cleaning line 222 away from the cleaning branch 231. In this way, the third delivery line 215 can transport the descaling agent from the descaling agent storage barrel to the cleaning line 222, and then enter each group of liquid outlet structures 100 through the cleaning line 222 and the cleaning branch 231.

[0090] The third control valve 216 is disposed in the third delivery pipeline 215 and can control the opening and closing of the third delivery pipeline 215. When the third control valve 216 is open, the descaling agent can enter the third delivery pipeline 215 and be delivered to the liquid outlet structure 100 via the cleaning pipeline 222 and the cleaning branch pipe 231. When the third control valve 216 is closed, the third delivery pipeline 215 is disconnected, and the descaling agent cannot enter the liquid outlet structure 100.

[0091] 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 pipeline 215 and enters each group of liquid outlet structures 100 through the cleaning pipeline 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.

[0092] See also Figures 1 to 4 、 Figure 6 In one embodiment, the cleaning tube group 210 also includes a fourth delivery pipeline 217 and a fourth control valve 218. One end of the fourth delivery pipeline 217 is connected to the air inlet 402 of the liquid discharge machine 1, and the other end of the fourth delivery pipeline 217 is connected to the cleaning pipeline 222. The fourth delivery pipeline 217 is used to deliver air, and the fourth control valve 218 is arranged on the fourth delivery pipeline 217 to control the on and off of the fourth delivery pipeline 217.

[0093] The fourth delivery line 217 is used to deliver air. The cabinet 40 has an air inlet 402, which is connected to the outside environment via a pipe. One end of the fourth delivery line 217 is connected to the air inlet 402, and the other end is connected to the end of the cleaning line 222 away from the cleaning branch 231. In this way, the fourth delivery line 217 can deliver air to the cleaning line 222, and then enter each group of liquid outlet structures 100 through the cleaning line 222 and the cleaning branch 231.

[0094] A fourth control valve 218 is disposed in the fourth delivery pipeline 217 and can control the opening and closing of the fourth delivery pipeline 217. When the fourth control valve 218 is open, air can enter the fourth delivery pipeline 217, thereby being delivered to the liquid outlet structure 100 via the purge pipeline 222 and the purge branch pipe 231. When the fourth control valve 218 is closed, the fourth delivery pipeline 217 is disconnected, and air cannot enter the liquid outlet structure 100.

[0095] 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 pipeline 217 and then enter each group of liquid outlet structures 100 through the cleaning pipeline 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.

[0096] 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.

[0097] See also Figures 1 to 6 In this embodiment, the cleaning structure 200 uses tap water, descaling agent, disinfectant, and air to clean the liquid outlet structure 100. A first delivery pipeline 211, a second delivery pipeline 213, a third delivery pipeline 215, and a fourth delivery pipeline 217 are arranged in parallel and connected to the end of the cleaning pipeline 222 away from the cleaning branch 231. A first control valve 212 is provided in the first delivery pipeline 211, a second control valve 214 is provided in the second delivery pipeline 213, a third control valve 216 is provided in the third delivery pipeline 215, and a fourth control valve 218 is provided in the fourth delivery pipeline 217.

[0098] 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 for the piping system 10. When the piping system 10 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.

[0099] It is worth noting that in the piping system 10, the cleaning structure 200 can adopt different cleaning methods for each group of liquid discharge structures 100 according to the different working states of the liquid discharge machine 1, and can also be cleaned after the liquid discharge machine 1 has been working for a period of time. Here, only the cleaning methods of the liquid discharge structure 100 before and after the liquid discharge machine 1 is turned off and turned on are described.

[0100] The liquid dispensing machine 1 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 dispensing pipe 120 to prevent the liquid material from deteriorating in the liquid dispensing pipe 120 for a long time (such as overnight), thereby preventing bacteria from growing in the liquid dispensing pipe 120 to ensure safety.

[0101] When the liquid discharge machine 1 cleans the liquid discharge structure 100 before shutting down, tap water is first introduced into each liquid discharge structure 100 for a first preset time to clean each liquid discharge structure 100; then, a descaling agent is introduced into each liquid discharge structure 100 for a second preset time and soaked for a third preset time; after soaking, tap water is introduced into each liquid discharge structure 100 for a fourth preset time; and then, a disinfectant is introduced into each liquid discharge structure 100 for a fifth preset time.

[0102] 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 pipeline 211. The water then enters each set of liquid outlet structures 100 through the cleaning pipeline 222 and the cleaning branch pipe 231. The tap water then flushes the liquid outlet pipes 120 of each set of liquid outlet structures 100 for a first preset time to flush any residual liquid material within the liquid outlet pipes 120. At this stage, each set of liquid outlet structures 100 can operate sequentially or in groups according to their serial numbers.

[0103] 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 pipeline 215, which then flows through the cleaning pipeline 222 and the cleaning branch pipe 231 into each group of liquid outlet structures 100. The descaling agent is then introduced into each group of liquid outlet structures 100 for a second preset time, ensuring that the descaling agent completely fills each group of liquid outlet structures 100. At this stage, each group of liquid outlet structures 100 can operate sequentially or in groups according to their serial number.

[0104] 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 10 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.

[0105] 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 pipeline 213, which then enters each group of liquid outlet structures 100 through the cleaning pipeline 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.

[0106] This completes the cleaning of the liquid outlet structure 100 before shutting down the liquid dispenser 1. 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 1 needs to be turned on before opening (or opening early). Since disinfectant is present in the liquid outlet pipe 120, the liquid dispenser 1 needs to be drained from the pipe 120 after startup.

[0107] After the liquid discharge machine 1 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.

[0108] 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 211. The water then enters each set of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. At this point, the tap water can flush the liquid outlet pipes 120 of each set of liquid outlet structures 100 for a sixth preset time to flush out any residual disinfectant in the liquid outlet pipes 120. At this stage, each set of liquid outlet structures 100 can operate sequentially according to their sequence number.

[0109] 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 can draw air into the fourth delivery pipe 217, and then enter each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. After the seventh preset time, the air can remove the tap water remaining on the inner wall of the liquid outlet pipe 120 of each group of liquid outlet structures 100, and the liquid outlet pipe 120 is emptied. In this way, the liquid dispenser 1 completes the cleaning of the liquid outlet structure 100, and the liquid outlet structure 100 can be used to prepare beverages.

[0110] 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.

[0111] 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.

[0112] Of course, in this application, the cleaning structure 200 can also be cleaned with other types of cleaning fluids, as long as a delivery system 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 and control valves are added and the cleaning steps are adjusted.

[0113] See also Figures 1 to 6In one embodiment, the cleaning structure 200 also includes a drainage mesh plate 240 and a drainage container. The drainage mesh plate 240 is arranged below the liquid outlet port 501. One end of the drainage container is connected to the drainage mesh plate 240, and the other end is connected to the sewer pipe outlet 404 of the liquid discharge machine 1.

[0114] Cabinet 40 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.

[0115] 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.

[0116] The piping system 10 of the present application uses a cleaning pipe 222 to achieve automatic cleaning of 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 10 is simple, which is easy to apply to the liquid outlet machine 1, simplifying the cleaning process of the liquid outlet machine 1 and facilitating the cleaning operation.

[0117] See also Figures 1 to 4 The present application further provides a liquid dispensing machine 1, comprising a cabinet 40, an operating table 50, and a piping system 10 as in any of the above embodiments. The operating table 50 has a liquid outlet port 501 and is disposed in the cabinet 40. The cabinet 40 houses a liquid storage container 60. The piping system 10 is disposed in the cabinet 40, and each liquid outlet structure 100 in the piping system 10 has one end connected to the liquid storage container 60 and the other end connected to the liquid outlet port 501. The cleaning structure 200 in the piping system 10 is disposed in the cabinet 40.

[0118] After the liquid discharge machine 1 of the present application adopts the pipeline system 10 of the above-mentioned embodiment, it can realize the cleaning of the liquid discharge structure 100. When the cleaning pump 221 is working, it can put the pipeline system 10 in a positive pressure state and ensure that the cleaning liquid can flow stably in the pipeline system 10 to prevent air leakage, achieve thorough cleaning, and ensure the cleaning effect.

[0119] See also Figure 7 , Figure 7 for Figure 4 The present application also provides a cleaning method for the pipeline system 10, which is applied to the pipeline system 10 in any of the above embodiments; the cleaning method comprises the following steps:

[0120] Before shutting down the liquid dispensing machine 1:

[0121] Running tap water into each liquid outlet structure 100 for a first preset time to clean each liquid outlet structure 100;

[0122] The descaling agent is introduced into each liquid outlet structure 100 for a second preset time, and then soaked for a third preset time;

[0123] After soaking, tap water is introduced into each liquid outlet structure 100 for a fourth preset time;

[0124] Passing disinfectant into each liquid outlet structure 100 for a fifth preset time;

[0125] After the liquid dispensing machine 1 is turned on:

[0126] Supplying tap water to each liquid outlet structure 100 for a sixth preset time;

[0127] Air is introduced into each liquid outlet structure 100 for a seventh preset time.

[0128] The liquid dispensing machine 1 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 dispensing pipe 120 to prevent the liquid material from deteriorating in the liquid dispensing pipe 120 for a long time (such as overnight), thereby preventing bacteria from growing in the liquid dispensing pipe 120 to ensure safety.

[0129] When the liquid discharge machine 1 cleans the liquid discharge structure 100 before shutting down, tap water is first introduced into each liquid discharge structure 100 for a first preset time to clean each liquid discharge structure 100; then, a descaling agent is introduced into each liquid discharge structure 100 for a second preset time and soaked for a third preset time; after soaking, tap water is introduced into each liquid discharge structure 100 for a fourth preset time; and then, a disinfectant is introduced into each liquid discharge structure 100 for a fifth preset time.

[0130] 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 pipeline 211. The water then enters each set of liquid outlet structures 100 through the cleaning pipeline 222 and the cleaning branch pipe 231. The tap water then flushes the liquid outlet pipes 120 of each set of liquid outlet structures 100 for a first preset time to flush any residual liquid material within the liquid outlet pipes 120. At this stage, each set of liquid outlet structures 100 can operate sequentially or in groups according to their serial numbers.

[0131] 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 pipeline 215, which then flows through the cleaning pipeline 222 and the cleaning branch pipe 231 into each group of liquid outlet structures 100. The descaling agent is then introduced into each group of liquid outlet structures 100 for a second preset time, ensuring that the descaling agent completely fills each group of liquid outlet structures 100. At this stage, each group of liquid outlet structures 100 can operate sequentially or in groups according to their serial number.

[0132] 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 10 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.

[0133] 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 pipeline 213, which then enters each group of liquid outlet structures 100 through the cleaning pipeline 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.

[0134] This completes the cleaning of the liquid outlet structure 100 before shutting down the liquid dispenser 1. 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 1 needs to be turned on before opening (or opening early). Since disinfectant is present in the liquid outlet pipe 120, the liquid dispenser 1 needs to be drained from the pipe 120 after startup.

[0135] After the liquid discharge machine 1 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.

[0136] 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 211. The water then enters each set of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. At this point, the tap water can flush the liquid outlet pipes 120 of each set of liquid outlet structures 100 for a sixth preset time to flush out any residual disinfectant in the liquid outlet pipes 120. At this stage, each set of liquid outlet structures 100 can operate sequentially according to their sequence number.

[0137] 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 can draw air into the fourth delivery pipe 217, and then enter each group of liquid outlet structures 100 through the cleaning pipe 222 and the cleaning branch pipe 231. After the seventh preset time, the air can remove the tap water remaining on the inner wall of the liquid outlet pipe 120 of each group of liquid outlet structures 100, and the liquid outlet pipe 120 is emptied. In this way, the liquid dispenser 1 completes the cleaning of the liquid outlet structure 100, and the liquid outlet structure 100 can be used to prepare beverages.

[0138] 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.

[0139] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0140] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
