Detailed Description of the Invention

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present application.

[0017] In the description of the embodiments of the present application, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0018] A liquid meal can be food in the form of a fluid or semi-fluid. Specifically, for example, a liquid meal can be beverages such as coffee, milk, and soy milk.

[0019] A liquid meal maker can make liquid meals and also has the function of cleaning the edible fluid pipeline through which the edible fluid flows.

[0020] In the related art, a liquid meal maker can include a liquid extraction pump and an edible fluid pipeline through which the edible fluid flows when making liquid meals. Among them, the liquid extraction pump can be used to extract the edible fluid into the edible fluid pipeline to complete the production of liquid meals according to the production process.

[0021] For example, taking the liquid meal maker as a coffee machine. The coffee machine can make coffee liquid according to different types of coffee to be made, and add some milk if necessary. And there will be a certain amount of oil in the coffee liquid, and rich protein in the milk. After these liquids flow through the pipeline in the coffee machine, there may be a certain residue in the pipeline. If exposed to the air for a long time, it may cause bacteria to grow in the pipeline.

[0022] In order to clean the edible fluid pipeline through which the edible fluid flows in the fluid meal making machine, after the staff configures the cleaning solution, they can place the container containing the cleaning solution in the fluid meal making machine. After starting the cleaning function of the fluid meal making machine, the pipeline inside the fluid meal making machine can be cleaned.

[0023] However, every time the edible fluid pipeline is cleaned, the staff prepares the cleaning solution, which reduces the work efficiency of the staff.

[0024] Therefore, in the related art, a dosing device for automatically dispensing a cleaning agent can be provided at the container containing the cleaning solution, so as to dispense a quantitative cleaning agent into the container according to the dosing instruction of the control unit, and form a cleaning solution after mixing a specified dose of water.

[0025] However, setting up a dosing device in the fluid meal making machine requires a large degree of adjustment to the internal structure of the fluid meal making machine. Specifically, for example, the dosing device may require an independent drive device and a control device, so an additional power supply circuit needs to be designed in the fluid meal making machine to supply power to the dosing device. In addition, for the convenience of maintenance and replacement of the dosing device, the dosing device may also need to be designed as a detachable module. These all increase the complexity of the internal structure of the fluid meal making machine to a certain extent.

[0026] Therefore, it is necessary to provide a simple technical solution suitable for internal cleaning of the fluid meal making machine.

[0027] Please refer to Figure 1 and Figure 2 , an embodiment of this specification provides a fluid meal making system 10. The fluid meal making system 10 may include a fluid meal making machine 100 having a liquid extraction pump 110; an edible fluid module 120 connected to the liquid extraction pump 110 through a pipeline, and the edible fluid module 120 can be used to provide edible fluid; a cleaning module 200 communicated with the liquid extraction pump 110 through a pipeline, and the cleaning module 200 can be used to provide a cleaning agent and a cleaning solution; the fluid meal making machine 100 has a liquid outlet mode of making fluid meals using the edible fluid provided by the edible fluid module 120, and a cleaning mode of cleaning the edible fluid pipeline through which the edible fluid flows using the cleaning solution provided by the cleaning module 200. The liquid outlet mode includes an edible fluid extraction function of extracting edible fluid from the edible fluid module 120; the cleaning mode includes a cleaning agent extraction function of extracting the cleaning agent from the cleaning module 200, and a cleaning solution extraction function of extracting the cleaning solution from the cleaning module 200. The edible fluid extraction function, the cleaning agent extraction function, and the cleaning solution extraction function reuse the liquid extraction pump 110.

[0028] In this embodiment, in the liquid meal production system 10, the cleaning module 200 can be used to provide a cleaning solution for the liquid meal maker 100 when performing a cleaning function, and the edible fluid module 120 can provide an edible fluid as a raw material for the liquid meal for the liquid meal maker 100. In a preferred embodiment, the liquid meal production system 10 can be used to make coffee beverages. Correspondingly, the liquid meal maker 100 can be a coffee machine. The edible fluid that the edible fluid module 120 can provide is milk. Specifically, the edible fluid module 120 can be a milk carton.

[0029] In this embodiment, the liquid extraction pump 110 can extract and transport liquids through the connected pipelines. The liquid extraction pump 110 can be integrated inside the liquid meal maker 100 so that it can perform work according to the actual functional logic during the operation of the liquid meal maker 100. Specifically, for example, the liquid extraction pump 110 can be used to extract and transport edible fluids, water, cleaning agents, cleaning solutions, etc. through the connected pipelines.

[0030] In this embodiment, the liquid meal can be a food in the form of a fluid or semi-fluid. The edible fluid can be a raw material for preparing the liquid meal. Of course, in some embodiments, the edible fluid in the liquid meal maker can also refer to the liquid meal. Specifically, for example, the edible fluid in a coffee machine can include coffee slurry or milk, etc. Or, in some embodiments, for a liquid meal production system for making hot milk, the edible fluid can be room temperature milk.

[0031] In this embodiment, the edible fluid pipeline can be the pipeline through which the edible fluid flows when making the liquid meal. Corresponding to the liquid meal production processes that need to be performed during the liquid meal production process, the edible fluid pipeline can be connected with devices for implementing the corresponding liquid meal production processes to complete the production of the liquid meal. Specifically, for example, the device can be a heating device, a foaming device, etc. The embodiments of this specification do not make specific limitations here.

[0032] In the present embodiment, the edible fluid module 120 can be used to provide an edible fluid. Specifically, for example, the edible fluid module 120 can be an edible fluid container, so that the edible fluid can be contained in the edible fluid container. Of course, in some cases, the edible fluid module 120 can also be an edible fluid preparation module, and the edible fluid output by the edible fluid preparation module can be used as a raw material for preparing a liquid meal. The edible fluid module 120 can be housed in the housing of the liquid meal maker 100, such that the edible fluid module 120 can be part of the liquid meal maker 100. Of course, the edible fluid module 120 can also be independent of the liquid meal maker 100 and be connected to the liquid extraction pump 110 of the liquid meal maker 100 through a pipeline. In some embodiments, the edible fluid module 120 can also refer to a pipeline for providing an edible fluid. For example, the edible fluid module 120 can also refer to the edible fluid extraction pipeline 121.

[0033] In the present embodiment, the cleaning module 200 can be used to provide a cleaning agent and a cleaning solution. The cleaning module 200 can be an independent component and be externally disposed on the liquid meal maker 100. For example, the cleaning module 200 can be a cleaning function accessory of the liquid meal maker 100. Of course, in some embodiments, the cleaning module 200 can also be provided in the liquid meal maker 100 and be part of the structure of the liquid meal maker 100 itself. The cleaning module 200 can be communicated with the liquid extraction pump 110 of the liquid meal maker 100 through a pipeline. A cleaning solution container 230 can be provided in the cleaning module 200. The cleaning solution container 230 can be used to contain the prepared cleaning solution. The cleaning module 200 can also accommodate a cleaning agent container 270 for providing a cleaning agent. In some embodiments, as a consumable, the cleaning agent container 270 is provided in the cleaning module 200 in a replaceable manner. It can be understood that the cleaning agent container 270 may not be part of the cleaning module 200, and the two can be considered to be in a cooperative use relationship.

[0034] In this embodiment, the liquid output mode may be the operating mode of the liquid meal maker 100 for making liquid meals. Specifically, for example, a user may issue an instruction to make a liquid meal through the operation interface provided by the liquid meal maker 100, and the liquid meal maker 100 makes a liquid meal for the user according to the instruction. In the liquid output mode, the liquid meal maker 100 may execute the function of extracting edible fluid. Specifically, when the function of extracting edible fluid is executed, the inlet of the liquid extraction pump 110 communicates with the edible fluid module 120 that accommodates the edible fluid, so that the liquid extraction pump 110 can drive the edible fluid in the edible fluid module 120 to enter the edible fluid pipeline. Further, the liquid meal maker 100 completes the production of the liquid meal according to the corresponding liquid meal production process. In some embodiments, the edible fluid may also be provided through an external pipeline. Correspondingly, when the function of extracting liquid meal is executed, the inlet of the liquid extraction pump 110 may communicate with the external pipeline.

[0035] In this embodiment, the liquid meal maker 100 may further include a cleaning mode for cleaning the edible fluid pipeline. Among them, the cleaning mode may include a cleaning agent extraction function for preparing a cleaning solution, and a cleaning solution extraction function for extracting the cleaning solution to clean the edible fluid pipeline.

[0036] In this embodiment, the cleaning solution may be a mixed solution for cleaning the residue of the edible fluid in the edible fluid pipeline. Among them, the cleaning solution may at least include a cleaning agent and a solvent. Among them, the cleaning agent may be a substance that can remove the residue of the edible fluid in the edible fluid pipeline. The solvent is a substance that can dissolve the cleaning agent, that is, the solvent can play a role in diluting the cleaning agent. In some embodiments, the solvent may be water. Of course, the solvent may not be limited to water, and may also be an aqueous solution suitable for dissolving the cleaning agent. Those skilled in the art can make corresponding selections of suitable solvents according to the actual product requirements and the knowledge they know.

[0037] In the cleaning mode, the liquid meal maker 100 may execute the cleaning solution extraction function of extracting the cleaning solution from the cleaning module 200. And, the liquid meal maker 100 may use the extracted cleaning solution to clean the edible fluid pipeline. The liquid meal maker 100 may execute the cleaning agent extraction function when the cleaning solution in the cleaning module 200 is exhausted, so as to prepare the cleaning solution by the extracted cleaning agent. Of course, in some embodiments, the liquid meal maker 100 may execute the cleaning agent extraction function first every time the cleaning mode is started, use the cleaning agent extracted from the cleaning module 200 to prepare the cleaning solution, and then execute the cleaning solution extraction function. The cleaning solution prepared each time may be adapted to the cleaning solution consumed for executing one cleaning mode. It can be understood that the cleaning solution prepared each time will be consumed during one operation of the cleaning mode.

[0038] Specifically, when the cleaning agent extraction function is executed, the cleaning agent container 270 accommodated in the cleaning module 200 can communicate with the inlet of the liquid extraction pump 110, enabling the liquid extraction pump 110 to extract the cleaning agent. When the solvent extraction function is executed, the solvent pipeline 300 that supplies the solvent can communicate with the inlet of the liquid extraction pump 110, enabling the liquid extraction pump 110 to extract the solvent so that the solvent and the cleaning agent are mixed to form a cleaning solution.

[0039] In this embodiment, by using the same liquid extraction pump 110 to provide driving power for the edible fluid extraction function, the cleaning agent extraction function, and the cleaning solution extraction function, the structure of the liquid meal production system can be simplified to a certain extent.

[0040] In some embodiments, the liquid meal maker 10 may further include a flushing mode for flushing the edible fluid pipeline with water. The flushing mode includes a water extraction function for extracting water; the water extraction function reuses the liquid extraction pump 110.

[0041] In this embodiment, water can be provided through a water pipeline. The water pipeline can provide water for flushing the edible fluid pipeline. In some embodiments, the water pipeline can also provide the water to be used when preparing the liquid meal. In some embodiments, the solvent used in the cleaning mode can also be water. Correspondingly, the water pipeline can also serve as the solvent pipeline 300. When the water extraction function is executed, the liquid extraction pump 110 can communicate with the solvent pipeline 300.

[0042] In some embodiments, the cleaning module 200 may include a cleaning liquid container 230; the cleaning mode further includes a solvent extraction function of using the liquid extraction pump 110 to extract the solvent into the cleaning liquid container 230; wherein the solvent is mixed with the cleaning agent extracted by the cleaning agent extraction function in the cleaning liquid container 230 to form a cleaning solution.

[0043] In this embodiment, the liquid meal maker 100 can automatically prepare a cleaning solution. Specifically, in the cleaning mode, the liquid meal maker 100 can first execute the cleaning agent extraction operation. At this time, driven by the liquid extraction pump 110, the cleaning agent is extracted from the cleaning agent container 270, and when the required dose is reached, the operation can be changed to execute the solvent extraction operation. After the cleaning agent extraction, there may be more cleaning agents left in the pipeline. After changing to the solvent extraction operation, the cleaning agents in the pipeline will be driven by the solvent and enter the cleaning liquid container 230 of the cleaning module 200 together to form a cleaning solution.

[0044] In some embodiments, a cleaning agent extraction pipeline 271 may be provided inside the cleaning module 200. The cleaning agent extraction pipeline 271 may be used to extend into a cleaning agent container 270 accommodated in the cleaning module 200. The cleaning liquid container 230 is connected with a liquid inlet pipeline 231 and a liquid outlet pipeline 232. The outlet of the liquid extraction pump 110 may be communicated with the liquid inlet pipeline 231. The liquid meal production system further includes a first flow direction control unit 330 that communicates a solvent pipeline 300 for providing a solvent, the cleaning agent extraction pipeline 271, the liquid outlet pipeline 232, and the inlet of the liquid extraction pump 110.

[0045] In this embodiment, a cleaning agent container 270 may be accommodated inside the cleaning module 200. It can be understood that the cleaning agent container 270 may be a replaceable consumable, such that the cleaning agent container 270 may not be an integral part of the cleaning module 200, but may be used in cooperation with the cleaning module 200. Further, a cleaning agent extraction pipeline 271 may be provided inside the cleaning module 200, and the cleaning extraction pipeline 271 may extend into the cleaning agent container 270 to extract the cleaning agent from the cleaning agent container 270 under the drive of the liquid extraction pump 110.

[0046] In this embodiment, the cleaning liquid container 230 may be connected with a liquid inlet pipeline 231 and a liquid outlet pipeline 232. The liquid inlet pipeline 231 may be used for liquid to flow into the cleaning liquid container 230. Specifically, when performing a cleaning agent extraction operation or a solvent extraction operation, the extracted cleaning agent and / or solvent will enter the cleaning liquid container 230 from the liquid inlet pipeline 231. The cleaning solution in the cleaning liquid container 230 may flow out of the cleaning liquid container 230 from the liquid outlet pipeline 232.

[0047] In this embodiment, according to the flow direction of the driven liquid, the liquid extraction pump 110 may have an inlet and an outlet. The liquid may enter the liquid extraction pump 110 from the inlet and flow out from the outlet under the drive of the liquid extraction pump 110. In this embodiment, the outlet of the liquid extraction pump 110 is communicated with the liquid inlet pipeline 231, such that the cleaning agent and / or solvent extracted by the liquid extraction pump 110 may flow into the cleaning liquid container 230 from the liquid inlet pipeline 231 under the drive of the liquid extraction pump 110.

[0048] In this embodiment, in the cleaning mode, the first flow direction control unit 330 can controllably connect the cleaning agent extraction pipeline 271 to the inlet of the liquid extraction pump 110 and cut off the liquid outlet pipeline 231 and the solvent pipeline 300. At this time, the liquid extraction pump 110 can extract the cleaning agent from the cleaning agent container 230 to realize the cleaning agent extraction function. Also, the first flow direction control unit 330 can controllably connect the solvent pipeline 300 to the inlet of the liquid extraction pump 110 and cut off the liquid outlet pipeline 232 and the cleaning agent extraction pipeline 271. At this time, the liquid extraction pump 110 can drive the extracted solvent and cleaning agent to flow into the cleaning liquid container 230 from the liquid inlet pipeline 231 to form a cleaning solution, realizing the solvent extraction function. Also, the first flow direction control unit 330 can controllably connect the liquid outlet pipeline 232 to the inlet of the liquid extraction pump 110 and cut off the cleaning agent extraction pipeline 271 and the solvent pipeline 300. The liquid extraction pump 110 extracts the cleaning solution from the cleaning liquid container 230 to realize the cleaning solution extraction function.

[0049] It can be understood that the liquid diet food maker 110 can be integrated with a control unit, and the control unit can execute the set control logic. Thus, the liquid diet food maker 110 can control the first flow direction control unit 330 to connect the required pipeline when the corresponding function needs to be executed.

[0050] In this embodiment, when the liquid diet food maker is in the cleaning mode, the preparation process of the cleaning solution can be automatically completed without manual operation, which brings convenience to the staff.

[0051] In this embodiment, the first flow direction control unit 330 can be an integral complex valve body, and can provide multiple interfaces, and can realize connecting any two of the cleaning agent extraction pipeline 271, the inlet of the liquid extraction pump 110, the liquid outlet pipeline 231 and the solvent pipeline 300 as required. Of course, the first flow direction control unit 330 can also be implemented by multiple valves, and the number of valves can be not limited, such as 1, 2, 3, 4, 5, etc., which will not be elaborated here.

[0052] In this embodiment, the first flow direction control unit 330 can be a component unit of the entire liquid meal production system 10. Specifically, the first flow direction control unit 330 can be arranged in a parallel structure with the cleaning module 200, the liquid meal production machine 100, and the edible fluid module 120. Of course, in some embodiments, in order to improve the integration degree of the liquid meal production system 10 and reduce space occupation, the first flow direction control unit 330 can be integrated into the cleaning module 200. Of course, when the liquid meal production system 10 further includes other accessories used in cooperation with the liquid meal production machine 100, the first flow direction control unit 330 can also be integrated into the corresponding accessories. Specifically, for example, the liquid meal production system 10 can further include a refrigeration device or a heating device used in cooperation with the liquid meal production machine 100, and the first flow direction control unit 330 can also be integrated into the refrigeration device or the heating device.

[0053] In this embodiment, the execution of the entire cleaning mode can be divided into several stages, namely, the stage of executing the cleaning agent extraction function, the stage of executing the solvent extraction function, and the stage of executing the cleaning liquid extraction function. The cleaning mode can be executed in the aforementioned order, so that when extracting the solvent, the residual cleaning agent in the pipeline can be brought into the cleaning liquid container 230 together.

[0054] In some embodiments, the first flow direction control unit 330 can include a first three-way solenoid valve 260 and a second three-way solenoid valve 240; a first intermediate pipeline 267 is connected between the first three-way solenoid valve 260 and the second three-way solenoid valve 240; the first three-way solenoid valve 260 can controllably connect the solvent pipeline 300 to the intermediate pipeline and cut off the cleaning agent extraction pipeline 271; or, connect the cleaning agent extraction pipeline 271 to the first intermediate pipeline 267 and cut off the solvent pipeline 300; or, cut off the solvent pipeline 300 and the cleaning agent extraction pipeline 271. The second three-way solenoid valve 240 can controllably connect the first intermediate pipeline to the inlet of the liquid extraction pump 110 and cut off the liquid outlet pipeline 232; or, connect the liquid outlet pipeline 232 to the inlet of the liquid extraction pump 110 and cut off the first intermediate pipeline 267.

[0055] In this embodiment, the first valve port 261 of the first three-way solenoid valve 260 can be used to connect the cleaning agent extraction pipeline 271. The second valve port 262 of the first three-way solenoid valve 260 can be connected to the solvent pipeline 300. The third valve port 263 of the first three-way solenoid valve 260 can be connected to the first valve port 241 of the second three-way solenoid valve 240 through the first intermediate pipeline 267.

[0056] The second valve port 242 of the second three-way solenoid valve 240 can communicate with the liquid outlet pipeline 232 of the cleaning liquid container 230. The third valve port 243 of the second three-way solenoid valve 240 can communicate with the inlet of the liquid extraction pump 110. In this way, by the combined use of the first three-way solenoid valve 260 and the second three-way solenoid valve 240, the function of the first flow control unit 330 can be realized.

[0057] Specifically, when the first three-way solenoid valve 260 connects the solvent pipeline 300 and the first intermediate pipeline 267 and cuts off the cleaning agent extraction pipeline 271, and the second three-way solenoid valve 240 connects the first intermediate pipeline 267 and the inlet of the liquid extraction pump 110 and cuts off the liquid outlet pipeline 232, the solvent pipeline 300 can communicate with the inlet of the liquid extraction pump 110 to extract the solvent from the solvent pipeline 300. When the first three-way solenoid valve 260 connects the cleaning agent extraction pipeline 271 and the first intermediate pipeline 267 and cuts off the solvent pipeline 300, and the second three-way solenoid valve 240 connects the first intermediate pipeline 267 and the inlet of the liquid extraction pump 110 and cuts off the liquid outlet pipeline 232, the cleaning agent extraction pipeline 271 can communicate with the inlet of the liquid extraction pump 110 to extract the cleaning agent from the cleaning agent container 270. When the second three-way solenoid valve 240 connects the liquid outlet pipeline 232 and the inlet of the liquid extraction pump 110 and cuts off the first intermediate pipeline 267, the liquid outlet pipeline 232 will be connected to the inlet of the liquid extraction pump 110 to extract the cleaning solution from the cleaning liquid container 230. At this time, the first three-way solenoid valve 260 can cut off the solvent pipeline 300 and the cleaning agent extraction pipeline 271. Of course, since the first intermediate pipeline 267 connected to the first three-way solenoid valve 260 is cut off, even if the first three-way solenoid valve 260 does not cut off the solvent pipeline 300 and the cleaning agent extraction pipeline 271, it can be considered that the two are cut off.

[0058] In some embodiments, the liquid meal production system 10 may further include a third three-way solenoid valve 210 disposed between the second three-way solenoid valve 240 and the inlet of the liquid extraction pump 110; the third three-way solenoid valve 210 is also connected to an edible fluid extraction pipeline 121. In the cleaning mode, the third three-way solenoid valve 210 connects the pipeline connected to the second three-way solenoid valve 240 and the inlet of the liquid extraction pump 110, and cuts off the edible fluid extraction pipeline 121; or, in the liquid outlet mode, the third three-way solenoid valve 210 connects the edible fluid extraction pipeline 121 and the inlet of the liquid extraction pump 110, and cuts off the pipeline connected to the second three-way solenoid valve 240.

[0059] In this embodiment, the first valve port 211 of the third three-way solenoid valve 210 can communicate with the third valve port 243 of the second three-way solenoid valve 240. The second valve port 212 of the third three-way solenoid valve 210 can communicate with the edible fluid extraction pipeline 121, and the third valve port 213 of the third three-way solenoid valve 210 communicates with the liquid outlet interface 350 of the cleaning module 200.

[0060] In this embodiment, by connecting the edible fluid extraction pipeline 121 through the third three-way solenoid valve 210, it is possible to switch the pipeline connected to the inlet of the liquid extraction pump 110 to be applicable to the liquid outlet mode or the cleaning mode by switching the third three-way solenoid valve 210. In some embodiments, the third three-way solenoid valve 210 can be arranged in the liquid meal maker 100. For example, the three-way solenoid valve originally connected to the edible fluid module 120 at the inlet of the liquid extraction pump 110 of the liquid meal maker 100 can be reused as the third three-way solenoid valve 210 in the foregoing text. Of course, in some embodiments, the third three-way solenoid valve 210 can also be arranged independently of the liquid meal maker 100.

[0061] In some embodiments, an edible fluid outlet 150, a waste outlet 160, and a second flow direction control unit 190 are arranged in the liquid meal maker 100. The second flow direction control unit 190 communicates with the edible fluid outlet 150, the waste outlet 160, the outlet of the liquid extraction pump 110, and the liquid inlet pipeline 231.

[0062] The second flow direction control unit 190 can controllably connect the outlet of the liquid extraction pump 110 and the liquid inlet pipeline 231, and cut off the edible fluid outlet 150 and the waste outlet 160 to perform the cleaning agent extraction function or the solvent extraction function. Or, the second flow direction control unit 190 can controllably connect the outlet of the liquid extraction pump 110 and the edible fluid outlet 150, and cut off the liquid inlet pipeline 231 and the waste outlet 160, so that the cleaning solution extracted by the liquid extraction pump 110 when performing the cleaning solution extraction function flows through the edible fluid outlet 150. Or, the second flow direction control unit 190 can controllably connect the outlet of the liquid extraction pump 110 and the waste outlet 160, and cut off the liquid inlet pipeline 231 and the edible fluid outlet 150.

[0063] In this embodiment, in the liquid outlet mode, during the process of performing the edible fluid extraction function, the second flow direction control unit 190 can connect the outlet of the liquid extraction pump 110 and the edible fluid outlet 150 of the liquid meal maker 100, and cut off the liquid inlet pipeline 231 and the waste outlet 160, so that the edible fluid entering the edible fluid pipeline can flow out from the edible fluid outlet 150.

[0064] Under the cleaning module, during the process of performing the cleaning agent extraction function or the solvent extraction function, the second flow direction control unit 190 can connect the outlet of the liquid extraction pump 110 and the liquid inlet pipeline 231 of the cleaning liquid container 230 and cut off the edible fluid outlet 150 and the waste outlet 160, so as to introduce the cleaning agent and the solvent into the cleaning liquid container 230 and mix them to form a cleaning solution. Further, during the process of performing the cleaning solution extraction function, the second flow direction control unit 190 can cut off the liquid inlet pipeline 231 and connect the outlet of the liquid extraction pump 110 to the edible fluid outlet 150, or connect the outlet of the liquid extraction pump 110 to the waste outlet 160, so as to clean the edible fluid outlet 150 or discharge the cleaning solution from the waste outlet 160.

[0065] In some embodiments, the second flow direction control unit 190 includes a fourth three-way solenoid valve 130 and a fifth three-way solenoid valve 140. An outlet pipeline 135 is connected between the fourth three-way solenoid valve 130 and the fifth three-way solenoid valve 140. The fourth three-way solenoid valve 130 can controllably connect the outlet of the liquid extraction pump 110 and the liquid inlet pipeline 231, and cut off the outlet pipeline 135; or connect the outlet of the liquid extraction pump 110 and the outlet pipeline 135, and cut off the liquid inlet pipeline 231. The fifth three-way solenoid valve 140 can controllably connect the outlet pipeline 135 and the waste outlet 160 of the liquid food maker 100, and cut off the edible fluid outlet 150 of the liquid food maker 100; or connect the outlet pipeline 135 and the edible fluid outlet of the liquid food maker, and cut off the waste outlet 160.

[0066] In the present embodiment, the first valve port 131 of the fourth three-way solenoid valve 130 can be communicated with the outlet of the liquid extraction pump 110. The second valve port 132 of the fourth three-way solenoid valve 130 can be communicated with the liquid inlet pipeline 231. The third valve port 133 of the fourth three-way solenoid valve 130 can be communicated with the first valve port 141 of the fifth three-way solenoid valve 140 through the outlet pipeline 135. The second valve port 142 of the fifth three-way solenoid valve 140 can be communicated with the waste outlet 160. The third valve port 143 of the fifth three-way solenoid valve 140 can be communicated with the edible fluid outlet 150.

[0067] In the present embodiment, in the cleaning mode, the fourth three-way solenoid valve 130 connects the liquid inlet pipeline 231 and the outlet of the liquid extraction pump 110 and cuts off the outlet pipeline 135, which can be used for the cleaning agent and / or solvent extracted in the cleaning mode to flow into the cleaning liquid container 230 through the liquid inlet pipeline 231. After the preparation of the cleaning solution is completed, the fourth three-way solenoid valve 130 can connect the outlet of the liquid extraction pump 110 and the outlet pipeline 135 and cut off the liquid inlet pipeline 231, and can switch between the waste outlet 160 and the edible fluid outlet 150 through the fifth three-way solenoid valve 140 to realize the cleaning of the outlet pipeline 135, the waste outlet 160 and the edible fluid outlet 150 by using the cleaning solution.

[0068] In some embodiments, a liquid level sensor 310 for measuring the remaining amount of the cleaning agent may be provided in the cleaning module 200.

[0069] In this embodiment, the liquid level sensor 310 may feedback a liquid level signal to the control unit of the liquid food machine 100. The control unit of the liquid food machine 100 can then determine the volume of the extracted cleaning agent according to the change in the liquid level in the cleaning agent container 270, and stop the cleaning agent extraction function when the required specified dose is reached. For example, control the first three-way solenoid valve 260 to block the cleaning agent extraction pipeline 271.

[0070] In this embodiment, the liquid level sensor 310 may adopt a resistive liquid level sensor or a photoelectric liquid level sensor.

[0071] In some cases, the cleaning agent container 270 can hold a large amount of cleaning agent. And the liquid food machine 100 only uses a small amount of cleaning agent to prepare the cleaning solution each time. So that the large amount of cleaning agent contained in the cleaning agent container 270 can be consumed for a long time. However, it is difficult for the staff to accurately estimate the time when the cleaning agent container needs to be replaced or the cleaning agent needs to be replenished. In this embodiment, by providing the liquid level sensor 310 to sense the remaining amount of the cleaning agent in the cleaning agent container 270. The liquid level sensor 310 can feedback a liquid level signal to the liquid food machine 100. Thus, when the cleaning agent in the cleaning agent container 270 is exhausted or nearly exhausted, the liquid food machine 100 can give a reminder to the staff, which brings convenience to the staff.

[0072] In some embodiments, a cleaning solution flow sensor 320 for sensing the flow rate of the cleaning solution flowing out of the cleaning solution container 230 may also be provided in the cleaning module 200. Specifically, the cleaning solution flow sensor 320 may be located at the outlet of the cleaning solution container 230 or in the liquid outlet pipeline 232. The cleaning solution flow sensor 320 can send a flow signal to the control unit of the liquid food machine 100, so that the liquid food machine 100 can control the dose of the extracted cleaning solution according to the received flow signal.

[0073] In some embodiments, the cleaning solution flow sensor 320 can also be used to detect whether the cleaning solution is exhausted. For example, the operation of the liquid pumping pump 110 can be controlled according to the flow signal. Specifically, when the cleaning solution flow sensor 320 does not detect any fluid passing through and the time without detecting any fluid passing through exceeds a specified threshold, it can be determined that the cleaning solution is exhausted, and the liquid food making machine 100 can control the liquid pumping pump 110 to stop pumping the cleaning solution. Further, based on this, it can also be controlled that the cleaning solution in the cleaning solution container 230 is completely consumed or a specified dose is consumed each time of cleaning. To a certain extent, it can reduce the possibility of bacteria breeding due to the incomplete use of the cleaning solution.

[0074] In some embodiments, the solvent pipeline 300 can also be provided with a solvent flow sensor for sensing the solvent flow rate flowing into the cleaning module 200, so as to control the extracted solvent dose according to the flow signal fed back by the received solvent flow sensor.

[0075] In some embodiments, the cleaning module 200 can be an external component separated from the liquid food making machine 100. The cleaning module 200 can be connected to the liquid pumping pump 110 of the liquid food making machine 100 through a pipeline.

[0076] Optionally, the liquid food making machine can be an existing liquid food making machine. By using the cleaning module 200 in combination with the existing liquid food making machine, it can conveniently clean the edible fluid pipeline in the liquid food making machine.

[0077] In addition, the liquid food making system 10 can also provide a cleaning module 200 installed in a detachable manner, and cooperate with the already designed liquid food making machine 100. While realizing the automatic preparation of the cleaning solution and cleaning the edible fluid pipeline with the cleaning solution, the structure of the original liquid food making machine 100 is retained, and to a certain extent, the design difficulty of the liquid food making system is reduced.

[0078] In this embodiment, the cleaning module 200 can be independently disassembled and assembled, and can be connected to the liquid food making machine through a pipeline, so as to be adapted to different liquid food making machines. This enables the liquid food making system 10 formed by the cleaning module 200 and the liquid food making machine to have more diverse combination relationships to be applicable to different application scenarios.

[0079] Specifically, for example, the cleaning module 200 and the liquid food making machine can respectively have independent housings. Through the interfaces provided on the outer part of the housings, the cleaning module 200 and the liquid food making machine can be connected by using pipelines. When using the liquid food making system 10, compared with the integrated housing of the cleaning module 200 and the liquid food making machine, the volumes of the separated cleaning module 200 and the liquid food making machine can be smaller and are easier to place and arrange.

[0080] In some embodiments, the cleaning module 200 may include a housing (not shown in the figure). The housing is formed with an isolation space separated from the outside and a receiving portion having an openable state; the cleaning liquid container 230 is received in the isolation space. When the receiving portion is in the open state, it is used for the user to put the cleaning agent container 270 into the receiving portion or take out the cleaning agent container 270 from the receiving portion.

[0081] In this embodiment, through the isolation space formed by the housing, the inside of the isolation space is separated from the outside. In this way, the cleaning container 230 received in the isolation space is inoperable and even possibly invisible to external users. Since the cleaning container 230 can be reused without replacement, it can avoid damage caused by user's misoperation to a certain extent. Further, the cleaning agent container 270 for containing the cleaning agent can be used as a consumable. When the cleaning agent in the cleaning agent container 270 is consumed, the cleaning agent container 270 can be directly replaced. In this way, since the receiving portion has an open state, it is convenient for the user to take out the cleaning agent container 270 from the receiving portion or put the cleaning agent container 270 into the receiving portion, which brings convenience to the user.

[0082] It can be understood that the open state can be merely a state provided by the receiving portion to facilitate the user to operate the cleaning agent container 270. A cover body may be provided on the housing corresponding to the receiving portion so that the receiving portion is in the open state by opening the cover body. Of course, when the cleaning agent container 270 does not need to be operated, the cover body can be covered on the receiving portion.

[0083] In this embodiment, the cleaning agent container 270 can be directly placed in the receiving portion. Of course, the receiving portion may also be provided with necessary limiting structures or fixing structures for the cleaning agent container 270.

[0084] In some embodiments, the first flow direction control unit 330 may also be received in the isolation space. In this way, the first flow direction control unit 330 can also be protected to a certain extent, avoiding damage caused by external user's misoperation and avoiding inconvenience to the user due to exposure to the outside.

[0085] In this embodiment, the cleaning module 200 may further include a solvent interface 340, a liquid inlet interface 360, and a liquid outlet interface 350 that extend out of the housing from the isolation space; wherein, the solvent interface 340 is used to connect to the solvent pipeline 300; the liquid inlet interface 360 is used to connect to the outlet of the liquid pumping pump 110; the liquid outlet interface 350 is used to connect to the inlet of the liquid pumping pump 110. The first flow direction control unit 330 can controllably connect the cleaning agent extraction pipeline 271 and the liquid outlet interface 350 and cut off the liquid outlet pipeline 232 and the solvent interface 340 to implement the cleaning agent extraction function; or, connect the solvent interface 340 and the liquid outlet interface 350 and cut off the liquid outlet pipeline 232 and the cleaning agent extraction pipeline 271 to implement the solvent extraction function; or, connect the liquid outlet pipeline 232 and the liquid outlet interface 350 and cut off the solvent pipeline 300 and the cleaning agent extraction pipeline 271 to implement the cleaning solution extraction function.

[0086] In this embodiment, the cleaning module 200 can be used as an independent module unit and can be connected to external pipelines through the external solvent interface 340, liquid inlet interface 360, and liquid outlet interface 350. For example, the solvent interface 340 can be used to connect to the solvent pipeline 300, the liquid inlet interface 360 can be used to connect to the outlet of the liquid pumping pump 110, and the liquid outlet interface 350 can be used to connect to the inlet of the liquid pumping pump 110. Furthermore, by arranging the first flow direction control unit 330 in the isolation space of the cleaning module 200, various pipeline connection functions can be realized inside the cleaning module 200, so that the cleaning module 200 can have better versatility.

[0087] In this embodiment, the technical features, functions, and effects realized by the first flow direction control unit 330 can be explained by referring to the foregoing, and will not be elaborated here.

[0088] In some embodiments, the first flow direction control unit 330 includes a first three-way solenoid valve 260 and a second three-way solenoid valve 240. The first three-way solenoid valve 260 can controllably connect the solvent interface 340 and the first intermediate pipeline and cut off the cleaning agent extraction pipeline 271; or, connect the cleaning agent extraction pipeline 271 and the intermediate pipeline and cut off the solvent interface 340; or, cut off the solvent interface 340 and the cleaning agent extraction pipeline 271. The second three-way solenoid valve 240 can controllably connect the first intermediate pipeline 267 and the liquid outlet interface 350 and cut off the liquid outlet pipeline 232; or, connect the liquid outlet pipeline 232 and the liquid outlet interface 350 and cut off the first intermediate pipeline 267.

[0089] In this embodiment, the first flow direction control unit 330 can be implemented by the first three-way solenoid valve 260 and the second three-way solenoid valve 240. Specifically, when the first three-way solenoid valve 260 connects the solvent interface 340 and the first intermediate pipeline 267 and cuts off the cleaning agent extraction pipeline 271, and the second three-way solenoid valve 240 connects the first intermediate pipeline 267 and the liquid outlet interface 350 and cuts off the liquid outlet pipeline 232, it can be used to implement the solvent extraction function. When the first three-way solenoid valve 260 connects the cleaning agent extraction pipeline 271 and the first intermediate pipeline 267 and cuts off the solvent interface 340, and the second three-way solenoid valve 260 connects the first intermediate pipeline 267 and the liquid outlet interface 350 and cuts off the liquid outlet pipeline 232, it can be used to implement the cleaning agent extraction function. When the second three-way solenoid valve 260 connects the liquid outlet pipeline 232 and the liquid outlet interface 350 and cuts off the first intermediate pipeline 267, it can be used to implement the cleaning solution extraction function. At this time, the first three-way solenoid valve 260 can cut off the solvent interface 340 and the cleaning agent extraction pipeline 271. Of course, since the first intermediate pipeline 267 connected to the first three-way solenoid valve 260 is cut off, even if the first three-way solenoid valve 260 does not cut off the solvent interface 340 and the cleaning agent extraction pipeline 271, it can be considered that the two are cut off.

[0090] In this embodiment, the technical features, functions, and effects included in the first flow direction control unit 330 can be explained in comparison with the foregoing and will not be elaborated here.

[0091] Please refer to Figure 3 In some embodiments, the liquid meal production system 10 may further include a refrigeration device 400 having a refrigeration unit 500. The refrigeration device 400 has a refrigerated space for accommodating the edible fluid module 120, and the refrigeration unit is used to refrigerate the refrigerated space 400. Among them, the refrigeration device 400 may also be integrated with the cleaning module 200.

[0092] In some cases, the edible fluid contained in the edible fluid module 120 needs to be stored at a low temperature to extend the shelf life of the edible fluid.

[0093] The refrigeration device 400 can be separated from the liquid meal maker 100. Specifically, the refrigeration device 400 and the liquid meal maker 100 may each have an independent housing and be connected by pipelines. So that the refrigeration device 400 can be used as an accessory device in cooperation with the liquid meal maker 100.

[0094] In this embodiment, if the refrigeration device 400, the liquid meal production module 100, and the cleaning module 200 are three separate components, it may cause the liquid meal production system to occupy a relatively large countertop space when in use. Therefore, the refrigeration device 400 and the cleaning module 200 can be integrated together, which can reduce the space occupied by the liquid meal production system 10. Moreover, integrating the refrigeration device 400 and the cleaning module 200 can also simplify the structure of the liquid meal production system to a certain extent.

[0095] In this embodiment, the refrigeration device 400 may have a device housing (not shown in the figure), and the housing of the cleaning module 200 can be integrated with the device housing of the refrigeration device 400. Of course, in some embodiments, the housing of the cleaning module 200 and the device housing may also be merely an assembly relationship, and both have their own independent housing structures.

[0096] In this embodiment, the refrigeration unit 500 can be a thermoelectric cooler, or an evaporator connected to a compressor.

[0097] Please refer to Figure 3 and Figure 4 . In some embodiments, the cleaning module 200 can include a cleaning liquid container 230 housed in an isolation space and a cleaning agent extraction pipeline 271 provided in the accommodating part. The cleaning liquid container 230 is connected with a liquid inlet pipeline 231 and a liquid outlet pipeline 232.

[0098] The refrigeration device 400 can also include a device solvent interface 420, a device liquid inlet interface 430, and a device liquid outlet interface 440 that extend out of the refrigeration device 400 from the inside of the refrigeration device 400. The refrigeration device 400 is also provided with a third flow direction control unit 410 and an edible fluid extraction pipeline 121. The edible fluid pipeline 121 is connected to the third flow direction control unit 410. Among them, the device solvent interface 420 is used to connect to the solvent pipeline 300; the device liquid inlet interface 430 is used to connect to the outlet of the liquid extraction pump 110; the device liquid outlet interface 440 is used to connect to the inlet of the liquid extraction pump 110.

[0099] The third flow direction control unit 410 can controllably connect the cleaning agent extraction pipeline 271 and the equipment liquid outlet interface 440, and cut off the equipment solvent interface 420, the liquid outlet pipeline 232, and the edible fluid extraction pipeline 121 to implement the cleaning agent extraction function; or, the third flow direction control unit 410 can controllably connect the equipment solvent interface 420 and the equipment liquid outlet interface 440, and cut off the cleaning agent extraction pipeline 271, the liquid outlet pipeline 232, and the edible fluid extraction pipeline 121 to implement the solvent extraction function; or, the third flow direction control unit 410 can controllably connect the liquid outlet pipeline 232 and the equipment liquid outlet interface 440, and cut off the equipment solvent interface 420, the cleaning agent extraction pipeline 271, and the edible fluid extraction pipeline 121 to implement the cleaning solution extraction function; or, the third flow direction control unit 410 can controllably connect the edible fluid extraction pipeline 121 and the equipment liquid outlet interface 440, and cut off the equipment solvent interface 420, the cleaning agent extraction pipeline 271, and the liquid outlet pipeline 232 to implement the edible fluid extraction function.

[0100] In this embodiment, the refrigeration equipment 400 can interact with the outside through the equipment solvent interface 420, the equipment liquid inlet interface 430, and the equipment liquid outlet interface 440. Inside, the third flow direction control unit 410 is encapsulated to control the liquid flow direction and implement multiple functions by connecting different pipelines.

[0101] In this embodiment, the third flow direction control unit 410 can receive the control instructions issued by the liquid meal maker 100 and connect the corresponding pipelines according to the received control instructions. The third flow direction control unit 410 can be a complex valve body as a whole and can provide multiple interfaces to connect any two of the equipment solvent interface 420, the cleaning agent extraction pipeline 271, the equipment liquid outlet interface 440, the liquid outlet pipeline 231, and the edible fluid extraction pipeline 121 as required.

[0102] In some embodiments, the third flow direction control unit 410 can include a first three-way solenoid valve 260, a second three-way solenoid valve 240, and a third three-way solenoid valve 210; a first intermediate pipeline 267 is connected between the first three-way solenoid valve 260 and the second three-way solenoid valve 240, and a second intermediate pipeline 268 is connected between the second three-way solenoid valve 240 and the third three-way solenoid valve 210.

[0103] The first three-way solenoid valve 260 can controllably connect the equipment solvent interface 420 and the first intermediate pipeline 267, and cut off the cleaning agent extraction pipeline 271; alternatively, connect the cleaning agent extraction pipeline 271 and the first intermediate pipeline 267, and cut off the equipment solvent interface 420; or cut off the equipment solvent interface 420 and the cleaning agent extraction pipeline 271. The second three-way solenoid valve 240 can controllably connect the first intermediate pipeline 267 and the second intermediate pipeline 268, and cut off the liquid outlet pipeline 232; alternatively, connect the liquid outlet pipeline 232 and the second intermediate pipeline 268, and cut off the first intermediate pipeline 267; or cut off the liquid outlet pipeline 232. The third three-way solenoid valve 210 can controllably connect the second intermediate pipeline 268 and the equipment liquid outlet interface 440, and cut off the edible fluid extraction pipeline 121; alternatively, connect the edible fluid extraction pipeline 121 and the equipment liquid outlet interface 440, and cut off the second intermediate pipeline 268.

[0104] In this embodiment, the third flow direction regulation unit 410 can be implemented by using the first three-way solenoid valve 260, the second three-way solenoid valve 240, and the third three-way solenoid valve 210.

[0105] Specifically, when the first three-way solenoid valve 260 connects the equipment solvent interface 420 and the first intermediate pipeline 267 and cuts off the cleaning agent extraction pipeline, the second three-way solenoid valve 240 connects the first intermediate pipeline 267 and the second intermediate pipeline 268 and cuts off the liquid outlet pipeline 232, and the third three-way solenoid valve 210 connects the second intermediate pipeline 268 and the equipment liquid outlet interface 440 and cuts off the edible fluid extraction pipeline 121, the inlet of the liquid extraction pump 110 can be communicated with the solvent pipeline 300 to realize the solvent extraction function. When the first three-way solenoid valve 260 connects the cleaning agent extraction pipeline 271 and the first intermediate pipeline 267 and cuts off the equipment solvent interface 420, the second three-way solenoid valve 240 connects the first intermediate pipeline 267 and the second intermediate pipeline 268 and cuts off the liquid outlet pipeline 232, and the third three-way solenoid valve 210 connects the second intermediate pipeline 268 and the equipment liquid outlet interface 440 and cuts off the edible fluid extraction pipeline 121, the inlet of the liquid extraction pump 110 can be communicated with the cleaning agent extraction pipeline 271 to extract the cleaning agent from the cleaning agent container 270. When the second three-way solenoid valve 240 connects the liquid outlet pipeline 232 and the second intermediate pipeline 268, cuts off the first intermediate pipeline 267, and the third three-way solenoid valve 210 connects the second intermediate pipeline 268 and the equipment liquid outlet interface 440 and cuts off the edible fluid extraction pipeline 121, the inlet of the liquid extraction pump 110 can be communicated with the liquid outlet pipeline 232 of the cleaning liquid container 230 to extract the cleaning solution from the cleaning liquid container 230. At this time, the first three-way solenoid valve 260 can cut off the equipment solvent interface 420 and the cleaning agent extraction pipeline 271. Of course, since the first intermediate pipeline 267 connected to the first three-way solenoid valve 260 is cut off, even if the first three-way solenoid valve 260 does not cut off the equipment solvent interface 420 and the cleaning agent extraction pipeline 271, it can be considered that the two are cut off. When the third three-way solenoid valve 210 connects the edible fluid extraction pipeline 121 and the equipment liquid outlet interface 440 and cuts off the second intermediate pipeline 268, the inlet of the liquid extraction pump 110 can be communicated with the edible fluid extraction pipeline 121 to realize the edible fluid extraction function. At this time, the first three-way solenoid valve 260 can cut off the equipment solvent interface 420 and the cleaning agent extraction pipeline 271, and the second three-way solenoid valve 240 can cut off the liquid outlet pipeline 232. Of course, since the second intermediate pipeline 268 connected to the second three-way solenoid valve 240 is cut off, even if the first three-way solenoid valve 260 does not cut off the equipment solvent interface 420 and the cleaning agent extraction pipeline 271, and the second three-way solenoid valve 240 does not cut off the liquid outlet pipeline 232, it can be considered that the three are cut off.

[0106] By integrating the third flow control unit 410 into the refrigeration device 400, the cleaning module 200, the solvent pipeline 300 and the edible fluid extraction pipeline 121 can be combined in an orderly manner, and more pipelines can be utilized, simplifying the internal structure. In some embodiments, the third flow control unit 410 can also be partially housed in the isolation space of the cleaning module 200. For example, the first three-way solenoid valve 260 and the second three-way solenoid valve 240 are housed in the isolation space of the cleaning module 200. Of course, in some embodiments, the third flow control unit 410 can also be completely located within the refrigeration device 400 but does not belong to the component of the cleaning module 200.

[0107] In some embodiments, the liquid meal production system 10 can include multiple edible fluid modules, and the three-way solenoid valves connecting the edible fluid modules can be correspondingly increased. For example, please refer to Figure 5 As shown, the liquid meal production system 10 can include a first edible fluid module 125 and a second edible fluid module 126. The first edible fluid module 125 can be connected to the third three-way solenoid valve 210, and a sixth three-way solenoid valve 280 can be added between the third three-way solenoid valve 210 and the liquid extraction pump 110. For the functional control of the sixth three-way solenoid valve 280, it can be understood by referring to the third three-way solenoid valve 210 and will not be elaborated here.

[0108] In this embodiment, an example is given where multiple edible fluid modules are all located in the refrigeration device 400. Of course, the embodiments of multiple edible fluid modules are not limited to Figure 5 as shown, and multiple edible fluid modules can also be set without a refrigeration device 400. Or, some of the multiple edible fluid modules are located inside the refrigeration device 400, and some are located outside the refrigeration device 400.

[0109] Please refer to Figure 6 . An embodiment of this specification also provides a cleaning method for a liquid meal production system. The cleaning method of the liquid meal production system can be applied to the control unit of the liquid meal production machine. The control unit can be integrated with a memory and a processing circuit. The memory can store at least partial program instructions for implementing the cleaning function, rinsing function, and liquid discharging function of the liquid meal production machine. The processing circuit is used to execute the program instructions to control the liquid meal production machine to perform corresponding functions.

[0110] The liquid meal production system can include: a liquid meal production machine having a liquid extraction pump, an edible fluid module connected to the liquid extraction pump through a pipeline, the edible fluid module being used to provide edible fluid; a cleaning module connected to the liquid extraction pump through a pipeline, the cleaning module including a cleaning liquid container and a cleaning agent container. The cleaning method of the liquid meal production system can include the following steps.

[0111] Step S110: Use a liquid extraction pump to extract a cleaning agent from the cleaning agent container into the cleaning liquid container.

[0112] Step S120: Use a liquid extraction pump to extract a solvent from the solvent pipeline into the cleaning liquid container to form a cleaning solution in the cleaning liquid container.

[0113] Step S130: Use a liquid extraction pump to extract the cleaning solution from the cleaning liquid container to clean the edible fluid pipeline through which the edible fluid flows in the liquid meal production system.

[0114] In this embodiment, when the cleaning agent extraction function is executed, the inlet of the liquid extraction pump is connected to the cleaning agent extraction pipeline. The cleaning agent can be driven into the cleaning liquid container by the liquid extraction pump. When the cleaning agent extraction function is executed, the inlet of the liquid extraction pump and the solvent pipeline can be connected. The solvent can be driven into the cleaning liquid container by the liquid extraction pump to mix with the cleaning agent to obtain a cleaning solution.

[0115] In some embodiments, when the cleaning solution extraction function is executed, the inlet of the liquid extraction pump can be connected to the liquid outlet pipeline of the cleaning liquid container. The formed cleaning solution can be driven by the liquid extraction pump to clean the edible fluid pipeline of the liquid meal making machine.

[0116] In some embodiments, the cleaning solution extraction function may further include: controlling the fourth three-way solenoid valve and the fifth three-way solenoid valve to discharge the cleaning solution from the waste outlet and / or the edible fluid outlet.

[0117] In some embodiments, the step of using a liquid extraction pump to extract a cleaning agent from the cleaning agent container into the cleaning liquid container includes: connecting the outlet of the liquid extraction pump to the inlet of the cleaning liquid container for containing the cleaning solution; connecting the cleaning agent container for containing the cleaning agent to the inlet of the liquid extraction pump; and turning on the liquid extraction pump until the cleaning agent extracted from the cleaning agent container reaches a first specified dose.

[0118] And the step of using a liquid extraction pump to extract a solvent from the solvent pipeline into the cleaning liquid container to form a cleaning solution in the cleaning liquid container includes: connecting the solvent pipeline for providing the solvent to the inlet of the liquid extraction pump; and turning on the liquid extraction pump until the solvent entering the cleaning liquid container reaches a second specified dose.

[0119] When the cleaning agent extraction function and the solvent extraction function are executed, the liquid meal production system can connect the outlet of the liquid extraction pump to the liquid inlet pipeline of the cleaning liquid container. Specifically, for example, please refer to Figure 2, the liquid meal production system 10 can connect the first valve port 131 and the second valve port 132 of the fourth three-way solenoid valve 130, so that the outlet of the liquid extraction pump 110 is connected to the accommodation liquid inlet pipeline 231. For example, corresponding to the cleaning agent extraction function, the liquid meal production system 10 can also connect the first valve port 261 and the third valve port 263 of the first three-way solenoid valve 260, the first valve port 241 and the third valve port 243 of the second three-way solenoid valve 240, and the first valve port 211 and the third valve port 213 of the third three-way solenoid valve 210, so that the cleaning liquid container 230 and the liquid extraction pump 110 are connected. After the liquid extraction pump 110 is turned on, the liquid extraction pump 110 can extract the cleaning agent in the cleaning agent container 270 to reach the first specified dose and introduce it into the cleaning liquid container 230. Corresponding to the cleaning agent extraction function, the liquid meal production system can also connect the second valve port 262 and the third valve port 263 of the first three-way solenoid valve 260, the first valve port 241 and the third valve port 243 of the second three-way solenoid valve 240, and the first valve port 211 and the third valve port 213 of the third three-way solenoid valve 210, so that the solvent interface 340 and the liquid extraction pump 110 are connected. After the liquid extraction pump 110 is turned on, the liquid extraction pump 110 can extract the solvent from the solvent interface 340 to reach the second specified dose and introduce it into the cleaning liquid container 230, so as to mix the cleaning agent to form a cleaning solution.

[0120] In this embodiment, the first specified dose may be the dose of the extracted cleaning agent. The second specified dose may be the dose of the extracted solvent. The first specified dose and the second specified dose can determine the ratio and dose of the cleaning solution. The first specified dose and the second specified dose can be preset or input by the user. Alternatively, the first specified dose and the second specified dose can also be calculated according to the specified ratio and dose of the cleaning solution. The embodiments of this specification do not make specific limitations here.

[0121] In some embodiments, the cleaning solution formed in the cleaning liquid container is adapted to be consumed during one execution of the cleaning mode.

[0122] In some cases, each time the fluid pipeline for cleaning is used, if there is still residual cleaning solution in the cleaning liquid container, the cleaning solution may deteriorate or breed bacteria. Therefore, during one execution of the cleaning mode of the liquid meal production machine, the prepared cleaning solution will be consumed during the operation of this cleaning mode. To a certain extent, the possibility of the cleaning solution deteriorating can be avoided.

[0123] In some embodiments, the method for detecting the consumption amount of the cleaning solution can be determined based on the liquid level sensor set in the cleaning module. Specifically, according to the liquid level in the cleaning liquid container fed back by the liquid level sensor, it can be determined whether the cleaning solution is consumed up.

[0124] In some embodiments, a flow sensor for detecting the liquid flow rate of the liquid flowing through the liquid outlet pipeline of the cleaning liquid container may be provided in the liquid outlet pipeline. Thus, when using the cleaning solution to clean the edible fluid pipeline, when the flow sensor fails to detect the cleaning solution flowing through the liquid outlet pipeline, it is determined that the cleaning solution has been consumed.

[0125] In some embodiments, it is also possible not to provide a sensor for detecting the cleaning solution, but to establish a corresponding relationship between the total dose of the prepared cleaning solution and the extraction flow rate of the liquid extraction pump. In this way, a duration for the liquid extraction pump to extract the cleaning solution can be set. When the time for extracting the cleaning solution reaches this specified duration, it is determined that the cleaning solution has been consumed.
