Description

Technical Field

[0001] This application relates to the field of cleaning technology for beverage preparation equipment, and in particular to beverage preparation systems and equipment. Background Technology

[0002] With the improvement of living standards, beverage making equipment such as coffee machines and self-service beverage machines are gradually appearing in more and more usage scenarios. Currently, the cleaning and descaling of beverage making equipment such as coffee machines are generally carried out using tablet-shaped cleaning agents. Taking the cleaning of the coffee machine brewing system as an example, when cleaning the brewer and the coffee machine tubing, the tablets are manually inserted into the brewer through the tablet channel next to the bean hopper at the top of the coffee machine. The tablets gradually dissolve in the brewer to clean the inside of the coffee system.

[0003] However, this type of beverage-making equipment has the following drawbacks in actual cleaning: First, a tablet needs to be added each time the equipment is cleaned, which still requires manual labor and incurs significant costs. Second, during the cleaning process, the tablet gradually dissolves in the beverage-making circuit. Because the circuit is constantly flowing, the tablet may not dissolve completely, potentially affecting the cleaning performance of the equipment. Utility Model Content

[0004] Therefore, it is necessary to provide a beverage preparation system and equipment to address the issue of how to improve the dissolution effect of detergents in order to enhance cleaning performance.

[0012] The liquid preparation container is rotatably connected to the support component via the switching component; when the liquid preparation container drives the switching component to rotate relative to the support component, the first liquid inlet can communicate with the second liquid inlet or the liquid inlet end of the second liquid preparation branch, and the first liquid outlet can communicate with the second liquid outlet or the liquid outlet end of the second liquid preparation branch.

[0013] In one embodiment, the dispensing container is detachably connected to the switching component, allowing the dispensing container to move the switching component relative to the supporting component between a first position and a second position. When the dispensing container rotates the switching component relative to the supporting component to the first position, the dispensing container and the switching component are relatively fixed, and the first inlet and the second inlet are connected, as are the first outlet and the second outlet. When the dispensing container rotates the switching component relative to the supporting component to the second position, the dispensing container is movable relative to the switching component, and the first inlet is connected to the inlet end of the second dispensing branch, as is the first outlet end.

[0014] In one embodiment, the line connecting the first liquid inlet and the first liquid outlet, the line connecting the second liquid inlet and the second liquid outlet, and the line connecting the liquid inlet end and the liquid outlet end of the second liquid distribution branch all pass through the rotation axis of the liquid distribution container relative to the carrier assembly.

[0015] In one embodiment, the beverage making system further includes a heating module; the heating module is provided with a first hot water pipe and a first heating chamber; the first heating chamber is used to heat liquid and is connected to the first hot water pipe; the switching module further includes a second solenoid valve assembly; one inlet end of the water injection module, the first solenoid valve assembly, the first heating chamber, and the second solenoid valve assembly is sequentially connected through the first hot water pipe; the second liquid outlet is connected to the beverage making circuit through the other inlet end of the second solenoid valve assembly; the beverage making circuit is connected to the outlet end of the second solenoid valve assembly; the second solenoid valve assembly is communicatively connected to the processing module; wherein, the processing module is used to control the conduction of the second solenoid valve assembly according to the control command.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] This application provides a beverage making device, including a beverage making system and a housing assembly, wherein the beverage making system is installed on the housing assembly.

[0035] like Figure 1 and Figure 2 As shown, the drinking water system includes a liquid preparation module 10, a water injection module 20, a drinking water preparation module 30, a switch module 40, and a processing module 50. Specifically, the water injection module 20 is connected to a water source. The water source can be municipal water or filtered water, etc. The drinking water preparation module 30 is equipped with a drinking water preparation circuit 310. The liquid preparation branch is connected to the drinking water preparation circuit 310.

[0036] The liquid preparation module 10 includes a liquid preparation device 100, which has a first liquid preparation branch 100a and a liquid preparation chamber 110a. The liquid preparation chamber 110a is used to hold detergent. The first liquid preparation branch 100a is provided with a second liquid inlet 120a and a second liquid outlet 120b at intervals, and the second liquid inlet 120a, the liquid preparation chamber 110a and the second liquid outlet 120b are connected in sequence. The second liquid outlet 120b is connected to the beverage preparation circuit 310.

[0037] The switching module 40 includes a first solenoid valve assembly 410. The processing module 50 is communicatively connected to the first solenoid valve assembly 410. The processing module 50 is used to control the first solenoid valve assembly 410 according to control commands, so that the first solenoid valve assembly 410 switches the water injection module 20 to the liquid dispensing branch of the second liquid outlet 120b or the drinking water preparation circuit 310.

[0038] Thus, the design of the dispensing chamber 110a ensures that the detergent dissolves completely within it, preventing excessive detergent from entering the beverage preparation circuit 310 and avoiding excessive residue in the circuit that could affect subsequent beverage preparation. Furthermore, the connection between the first dispensing branch 100a and the dispensing chamber 110a increases the mixing space between water and detergent, thereby improving detergent dissolution and ultimately enhancing cleaning effectiveness.

[0039] To facilitate understanding, the following explanations will be provided using different control commands in various scenarios.

[0040] In some embodiments, the control commands include beverage preparation commands and cleaning commands.

[0041] When the processing module 50 controls the first solenoid valve assembly 410 according to the beverage making instruction, the first solenoid valve assembly 410 is in the first mode, so that the water injection module 20 is connected to the beverage making circuit 310 through the first solenoid valve assembly 410 to complete the beverage making.

[0042] When the processing module 50 controls the first solenoid valve assembly 410 according to the cleaning command, the first solenoid valve assembly 410 is in the second mode, so that the water injection module 20, the first solenoid valve assembly 410 and the liquid distribution branch are connected to complete the preparation of the cleaning solution.

[0043] It should be noted that the switching between the first solenoid valve assembly 410 or other solenoid valve assemblies in the first mode and the second mode can be determined according to the actual structure of the solenoid valve assembly.

[0044] The switching between the first and second modes of the solenoid valve assembly refers to the solenoid valve assembly being connected to at least two branches, with the switching between these branches achieved through the switching of the solenoid valve assembly between the first and second modes. Specifically, when the solenoid valve assembly consists of multiple solenoid valve elements installed in different branches, the connection to at least one branch can be achieved through the control of these multiple solenoid valve elements. When the solenoid valve assembly is a multi-way valve, such as a design with one inlet and two outlets, or two inlets and one outlet, it allows for the switching of connection to different branches at different workstations.

[0045] In one example, the solenoid valve assembly includes valve one and valve two. Valve one and valve two are connected to different branches, and one controls the connection of the corresponding branch. For example, the water injection module 20 is connected to the drinking circuit 310 via valve one. The water injection module 20 is connected to the first liquid inlet 130a via valve two. The first solenoid valve assembly 410 is in a first mode when valve one is open and valve two is closed. The second mode is when valve one is open and valve two is closed.

[0046] In another example, the solenoid valve assembly may include a multi-way valve. Switching between different ports of the multi-way valve, with each port connected to a different branch, enables switching of connections to different branches. The example illustrates that the first solenoid valve assembly 410 has an inlet end and at least two outlet ends. One outlet end (hereinafter referred to as outlet end one) is connected to the beverage preparation circuit 310. The other outlet end (hereinafter referred to as outlet end two) is connected to the first liquid inlet section 130a. In the first mode, the first solenoid valve assembly 410 is in a first mode where the inlet end is connected to outlet end one, but not to outlet end two. In the second mode, the first solenoid valve assembly 410 is in a second mode where the inlet end is not connected to outlet end one, but is connected to outlet end two.

[0047] In some embodiments, combined with Figure 1 , Figure 3 as well as Figure 4 As shown, the liquid preparation device 100 also includes a liquid preparation container 110, a switching assembly 120, and a carrying assembly 130. The liquid preparation container 110 has a liquid preparation chamber 110a, and the switching assembly 120 has a second liquid preparation branch 100b, a second liquid inlet 120a, and a second liquid outlet 120b. The first liquid preparation branch 100a and the second liquid preparation branch 100b are spaced apart. The second liquid preparation branch 100b is not connected to the liquid preparation chamber 110a. The second liquid inlet 120a, the liquid preparation chamber 110a, and the second liquid outlet 120b are sequentially connected to form the first liquid preparation branch 100a.

[0048] The liquid preparation container 110 is rotatably connected to the support component 130 via the switching component 120. When the liquid preparation container 110 drives the switching component 120 to rotate relative to the support component 130, the first liquid inlet 130a can communicate with the liquid inlet end of the second liquid inlet 120a or the second liquid preparation branch 100b, and the first liquid outlet 130b can communicate with the liquid outlet end of the second liquid outlet 120b or the second liquid preparation branch 100b.

[0049] It is understandable that the first liquid preparation branch 100a can be used to prepare acidic or alkaline detergent solutions through the liquid preparation chamber 110a to achieve acid washing or alkaline washing; the second liquid preparation branch 100b is used to flow liquid water to achieve water washing, that is, the water washing function can be achieved through the connection of the second liquid preparation branch 100b.

[0050] Thus, when the switching component 120 and the carrying component 130 are in active cooperation, the switching between the first liquid dispensing branch 100a and the second liquid dispensing branch 100b can be realized to achieve the connection of different liquid dispensing branches, enrich the cleaning scenarios of the liquid circuit, reduce the tedious operation of manually adding different tablets, and improve the performance of the beverage preparation equipment.

[0051] Furthermore, by rotating the liquid preparation container 110 relative to the support component 130 via the switching component 120, the first liquid preparation branch 100a or the second liquid preparation branch 100b can be connected to the first liquid inlet 130a and the first liquid outlet 130b. This reduces the difficulty of switching the first liquid preparation branch 100a or the second liquid preparation branch 100b, requiring only a simple rotation of the liquid preparation container 110 or the switching component 120, which improves operational convenience.

[0052] Furthermore, in one embodiment, such as Figure 5 As shown, the line connecting the first liquid inlet 130a and the first liquid outlet 130b, the line connecting the second liquid inlet 120a and the second liquid outlet 120b, and the line connecting the liquid inlet end and the liquid outlet end of the second liquid distribution branch 100b all pass through the rotation axis of the liquid distribution device 100 relative to the carrier component 130.

[0053] This design makes the liquid dispensing device 100 more symmetrical in structure, allowing its rotation trajectory relative to the support component 130 to be circular. This reduces the design complexity of the support component 130, ensures alignment between the inlet and outlet sections, and facilitates switching between different liquid dispensing branches. Furthermore, the circular rotation trajectory of the support component 130, unlike elliptical or hyperbolic motion trajectories, reduces the computational complexity for the processing module 50 in driving the rotation of the support component 130.

[0054] Optionally, in one embodiment, the number of first liquid dispensing branches 100a can be multiple, and the second liquid inlet 120a and the second liquid outlet 120b corresponding to each first liquid dispensing branch 100a both pass through the rotation axis. In this way, at least two washing modes that can be cleaned with detergent and one washing mode that can be washed with water can be formed, greatly enriching the cleaning scenarios and optimizing the cleaning performance of the beverage preparation system.

[0055] See you later Figure 4 In conjunction with the above embodiment where the dispensing container 110 is rotatably engaged with the supporting component 130 via the switching component 120, the dispensing container 110 and the switching component 120 are further detachably connected, and the dispensing container 110 can drive the switching component 120 to move between a first position and a second position relative to the supporting component 130. When the dispensing container 110 drives the switching component 120 to rotate relative to the supporting component 130 to the first position, the dispensing container 110 and the switching component 120 are relatively fixed, and the first liquid inlet 130a is connected to the second liquid inlet 120a, and the first liquid outlet 130b is connected to the second liquid outlet 120b. When the dispensing container 110 drives the switching component 120 to rotate relative to the supporting component 130 to the second position, the dispensing container 110 can move relative to the switching component 120, and the first liquid inlet 130a is connected to the liquid inlet end of the second dispensing branch 100b, and the first liquid outlet 130b is connected to the liquid outlet end of the second dispensing branch 100b.

[0056] It is understandable that when the liquid preparation container 110 is installed in the first position (i.e., the installation position), the liquid can enter the liquid preparation chamber 110a through the first liquid preparation branch 100a, mix with the detergent, and then flow out from the first liquid outlet 130b, thus realizing the cleaning mode of washing the beverage preparation circuit 310 with detergent.

[0057] When the liquid dispensing container 110 is disassembled to the second position (i.e., the disassembled position), the liquid can flow directly from the first liquid inlet 130a to the first liquid outlet 130b through the second liquid dispensing branch 100b. At this time, it can be used for ordinary cleaning without adding detergent. The cleaning mode of the drinking circuit 310 is simply washed with liquid water.

[0058] Switching between different cleaning scenarios is possible simply by disassembling the dispensing container 110, flexibly adapting to various cleaning needs and improving ease of use. It also prevents leakage from the dispensing device 100 if the first dispensing branch is connected even when the dispensing container 110 is not properly installed, thus improving the safety of the dispensing device 100. Furthermore, since the dispensing container 110 and the switching component 120 are detachably connected, users can replace the dispensing container 110 at any time, improving the maintenance convenience of the dispensing device 100 and reducing operating costs.

[0059] like Figure 1 as well as Figure 6 As shown, in any embodiment of the above-described switch module 40 and liquid dispensing module, the liquid dispensing module further includes a pipeline assembly 101.

[0060] In one embodiment, the piping assembly 101 includes at least two first pipes 101a. The liquid dispensing module 10 includes at least two liquid dispensing devices 100 (such as a first liquid dispensing device and a second liquid dispensing device), and the liquid dispensing chambers 110a corresponding to the at least two liquid dispensing devices 100 are used to load different detergents. The liquid dispensing module 10 also includes at least two first switching valves 102. The first pipes 101a are correspondingly arranged with the liquid dispensing devices 100, and the first pipes 101a are connected between the first solenoid valve assembly 410 and the second liquid inlet 120a. The first switching valves 102 are connected to the first pipes 101a. The processing module 50 is communicatively connected to the first switching valves 102, and the processing module 50 is used to control the opening of the first switching valves 102 according to control commands.

[0061] In another embodiment, the piping assembly 101 further includes a second piping 101b. A water source is sequentially connected to a first liquid inlet 130a, a first liquid distribution branch 100a or a second liquid distribution branch 100b, and a first liquid outlet 130b via the first piping 101a to form a first washing branch. The water source is connected to the second piping 101b to form a second washing branch. The valve assembly includes a first switching valve 102 and a second switching valve 103. The first switching valve 102 is connected to the first piping 101a and is used to enable the flow of the first piping 101a. The second switching valve 103 is connected to the second piping 101b and is used to enable the flow of the second piping 101b. The water source can be municipal water or filtered water, etc. Both the first piping 101a and the second piping 101b are connected to the drinking water preparation assembly. That is, both the first washing branch and the second washing branch are connected to the drinking water preparation circuit 310.

[0062] In one example scenario, when the first switching valve 102 is open and the second switching valve 103 is closed, the first washing branch is connected, and the second washing branch is disconnected, allowing other components to be cleaned with detergent solution. In another example scenario, when the first switching valve 102 is closed and the second switching valve 103 is open, the first washing branch is disconnected, and the second washing branch is connected, allowing other components to be cleaned with liquid water. Thus, by controlling the on / off state of the first and second switching valves 102 and 103, the switching between the first and second washing branches can be achieved, enabling switching between detergent solution cleaning and water cleaning, thus meeting various washing needs.

[0063] Further, optionally, in one embodiment, the piping assembly 101 further includes a third piping 101c. A plurality of first piping 101a are connected in parallel to the third piping 101c, and the third piping 101c is connected to the beverage preparation circuit 310. The processing module 50 is communicatively connected to the first switching valve 102, and the processing module 50 is used to control the first switching valve 102 to open according to control commands.

[0064] Thus, by setting the third pipe 101c, the detergent solution flowing out from the second liquid outlet 120b can utilize the third pipe 101c to increase the mixing space, thereby improving the preparation quality of the detergent solution.

[0065] In addition, in one embodiment, the third pipe 101c is provided with at least two outlets, which are used to connect to at least two beverage-making components one by one. Specifically, for example, taking a beverage-making module 30 that includes two beverage-making components, the two beverage-making components are respectively provided with a first beverage-making circuit 311 and a second beverage-making circuit 312. In this case, the multiple outlets can be used to clean different beverage-making components, so that different detergent solutions can be delivered to the first beverage-making circuit 311 or the second beverage-making circuit 312 through different outlets, thereby avoiding excessive interference of residual detergent solution with new detergent solution when the pipeline is shared, and ensuring the cleaning effect. In one example, the third pipe 101c is provided with two outlets at opposite ends to increase the mixing space of the detergent solution. In another example, the first pipe 101a and the second pipe 101b are connected in parallel to the third pipe.

[0066] Additionally, optionally, in one embodiment, combining Figure 1 as well as Figure 6 As shown, the third pipe 101c is provided with a first connecting end A, a second connecting end B, and a third connecting end C at intervals. The second pipe 101b is connected to the third pipe 101c through the first connecting end A, and the liquid outlet is connected to the third pipe 101c through the second connecting end B. The first connecting end A and the second connecting end B are arranged adjacent to each other. In one example, the third connecting end C is located on the side of the second connecting end B away from the side where the first connecting end A is located. In another example, the third connecting end C is located on the side of the first connecting end A away from the side where the second connecting end B is located.

[0067] Thus, the liquid flow direction in the third pipe 101c will be either the first connection end A, the second connection end B, and the third connection end C, or the second connection end B, the first connection end A, and the third connection end C. This ensures that the liquids at the first connection end A and the second connection end B are thoroughly mixed, and that the detergent solution flowing out from the third connection end C has a uniform concentration distribution, thereby improving the quality of the detergent solution preparation and enhancing the cleaning effect.

[0068] In some implementations, see back Figure 1 as well as Figure 6 The piping assembly 101 also includes multiple pressure relief and waste discharge piping assemblies 101. The liquid dispensing module 10 also includes multiple pressure relief valves 460 and safety valves 470. The pressure relief valves 460 and safety valves 470 are connected and disposed in different pressure relief and waste discharge piping assemblies 101. The pressure relief and waste discharge piping assemblies 101 are connected to the first washing branch or other pipelines such as the first heating branch and the second heating branch, so that pressure can be relieved for the first washing branch through the pressure relief valves 460. The safety valves 470 are used to ensure the pressure safety of the pipeline. Both the pressure relief valves 460 and the safety valves 470 are common components of the liquid circuit system of beverage equipment, and will not be described in detail in this application.

[0069] In conjunction with any embodiment of the above-described beverage preparation system, such as Figure 7 as well as Figure 8 As shown, the beverage making system also includes a heating module 60. The switching module 40 also includes a second solenoid valve assembly 420. The heating module 60 is provided with a first hot water pipe 600a and a first heating chamber 600b. A first heating element is provided in the first heating chamber 600b, so that the first heating element can heat the liquid in the first heating chamber 600b.

[0070] The first solenoid valve assembly 410, the first heating chamber 600b, and the inlet end of the beverage-making circuit 310 are sequentially connected via the first hot water pipe 600a to form a first heating branch. That is, the first solenoid valve assembly 410 is connected to the beverage-making circuit 310 via the first hot water pipe 600a. The second solenoid valve assembly 420 is connected to and disposed within the first hot water pipe 600a, and is located between the first heating chamber 600b and the inlet end of the beverage-making circuit 310. The outlet ends of the first liquid outlet 130b and the second pipe 101b are both connected to the inlet end of the beverage-making circuit 310 via the second solenoid valve assembly 420.

[0071] The second solenoid valve assembly 420 is communicatively connected to the processing module 50. The processing module 50 is used to control the second solenoid valve assembly 420 to enable the conduction of the first heating branch, the first washing branch, or the second washing branch.

[0072] To facilitate understanding, in conjunction with the above description of the switching between the first and second modes of the solenoid valve assembly, the following description will be based on an implementation scenario in which the first solenoid valve assembly 410 and the second solenoid valve assembly 420 switch and cooperate.

[0073] In one example scenario, the processing module 50 controls the first solenoid valve assembly 410 and the second solenoid valve assembly 420 to be in the first mode, so that the water injection module 20 is connected to the first heating branch through the first solenoid valve assembly 410, and the first heating branch is connected to the drinking circuit 310 through the second solenoid valve assembly 420. At this time, the first washing branch and the second washing branch are not connected. When clean water enters the heating chamber, it can be heated to form hot water, and enters the drinking circuit 310 through the second solenoid valve assembly 420 to brew hot water in the drinking circuit 310.

[0074] In another example scenario, the processing module 50 controls the first solenoid valve assembly 410 and the second solenoid valve assembly 420 to be in the second mode, so that the water injection module 20 is connected to the first washing branch or the second washing branch through the first solenoid valve assembly 410. The connection switching process between the first and second washing branches can be implemented with reference to the control process of the first switching valve 102 and the second switching valve 103 in the above embodiments. Subsequently, the outlet end of the first liquid outlet 130b or the second pipe 101b is connected to the inlet end of the drinking circuit 310 through the second solenoid valve assembly 420 to achieve rinsing of the drinking circuit 310 by the first or second washing branch.

[0075] In another example scenario, the processing module 50 controls the first solenoid valve assembly 410 and the second solenoid valve assembly 420 to be in the second mode, with the first switching valve 102 in the open state and the second switching valve 103 in the closed state. This allows the detergent solution in the first washing branch to enter the beverage-making circuit 310. Then, after a period of time, once a certain amount of detergent solution has been stored in the beverage-making circuit 310, the processing module 50 controls the first solenoid valve assembly 410 and the second solenoid valve assembly 420 to be in the first mode. This allows the first heating branch to supply hot water to the beverage-making circuit 310, enabling the hot water and detergent solution to mix within the circuit. This improves the solubility of the detergent in the beverage-making circuit 310, thereby enhancing the cleaning performance of the detergent solution on the dirt within the circuit.

[0076] The switching between the first and second modes of the second solenoid valve assembly 420 can be referred to the description of the switching between the first and second modes of the solenoid valve assembly in the above embodiments. In one example, valve one of the second solenoid valve assembly 420 is connected to the first heating branch, the first washing branch and the second washing branch are connected in parallel to a series pipeline, and valve two is connected to the series pipeline. In another example, the second solenoid valve assembly 420 has at least two inlet ends and an outlet end, one inlet end is connected to the first liquid outlet 130b, and the other inlet end is connected to the outlet end of the first hot water pipe 600a.

[0077] Thus, through the cooperation of the first solenoid valve assembly 410 and the second solenoid valve assembly 420, both beverage preparation and cleaning functions can be provided, and the cleaning performance can be optimized through the cooperation of the first solenoid valve assembly 410 and the second solenoid valve assembly 420.

[0078] Furthermore, in one embodiment, such as Figure 6 as well as Figure 7 As shown, the heating module 60 also includes a second hot water pipe 600c. The switching module 40 further includes a third solenoid valve assembly 430. The first liquid outlet 130b, the inlet end of the first heating chamber 600b, and the outlet end of the first heating chamber 600b are sequentially connected via the second hot water pipe 600c. The third solenoid valve assembly 430 is connected and disposed in the second hot water pipe 600c. The processing module 50 is communicatively connected to the third solenoid valve assembly 430.

[0079] Understandably, in one example scenario, when the processing module 50 controls the third solenoid valve assembly 430 to be in the open state, the detergent solution in the first washing branch (such as the first liquid dispensing branch 100a and the second liquid dispensing branch 100b in the above embodiment) can enter the first heating chamber 600b for cleaning to remove the scale in the heating chamber.

[0080] In another example scenario, when the processing module 50 controls the third solenoid valve assembly 430 to be in the closed state, the washing liquid in the first washing branch cannot enter the first heating chamber 600b for cleaning. If the control of the first solenoid valve assembly 410 and the second solenoid valve assembly 420 in the above embodiment is referred to at this time, the first heating branch can be turned on.

[0081] Thus, through this embodiment, the first heating chamber 600b can be cleaned, thereby improving the overall cleanliness of the beverage making equipment and enriching the cleaning scenarios.

[0082] In conjunction with any embodiment of the beverage preparation circuit 310 described above, such as Figure 6 as well as Figure 8 As shown, the beverage-making circuit 310 includes a first beverage-making circuit 311 and a second beverage-making circuit 312. The second solenoid valve assembly 420 is connected to the outlet end of the first beverage-making circuit 311, so that the switching module 40 can control the first beverage-making circuit 311 to switch between beverage-making and washing functions as illustrated in the example scenario above. The first liquid outlet 130b is connected to the inlet end of the second beverage-making circuit 312. In one example, the outlet end of the third pipe 101c is connected to the inlet end of the second beverage-making circuit 312.

[0083] Specifically, in one embodiment, see back Figure 7The third solenoid valve assembly 430 includes a first valve V1. The second hot water pipe 600c includes a third section P1 and a fourth section P2. The third section P1 connects the first liquid outlet 130b (or the outlet end of the third pipe 101c) and the inlet end of the first heating chamber 600b. The fourth section P2 connects to the outlet end of the first heating chamber 600b and is used to discharge high-temperature liquid. The first valve V1 is connected to the fourth section P2.

[0084] When the first valve V1 is open, the second hot water pipe 600c can discharge high-temperature liquid. This high-temperature liquid can be waste liquid or hot water, which can be further explained with an example later.

[0085] Furthermore, in some embodiments, see back Figure 7 The third solenoid valve assembly 430 also includes a second valve V2. The second hot water pipe 600c also includes a fifth section P3. The fifth section P3 connects the outlet end of the first heating chamber 600b and the second drinking circuit 312. The second valve V2 is connected to the fifth section P3.

[0086] Furthermore, in some embodiments, see back Figure 6 as well as Figure 7 The heating module 60 also includes a second heating chamber 600d, which is connected to the fourth segment P2 and is located between the outlet end of the first heating chamber 600b and the first valve V1. The third solenoid valve assembly 430 also includes a third valve V3, and the second hot water pipe 600c also includes a sixth segment P4, which is connected between the outlet end of the second heating chamber 600d and the second drinking circuit 312. The third valve V3 is connected to the sixth segment P4.

[0087] Specifically, as an example, when the first solenoid valve assembly 410 is in the first mode and the second solenoid valve assembly 420 is in the second mode, the processing module 50 also controls the first valve V1 and the second valve V2 to be closed and the third valve V3 to be opened. At this time, the hot water in the first heating chamber 600b enters the second heating chamber 600d for further heating to form steam. The steam enters the second beverage making circuit 312 to realize the beverage making function.

[0088] Furthermore, in an example scenario, see back Figure 7 The switching module 40 also includes a fourth solenoid valve assembly 440, which is connected between the outlet end of the mixing chamber within the second beverage making circuit 312 and the outlet end of the second beverage making circuit 312. Thus, the fourth solenoid valve assembly 440 can control whether the liquid in the second beverage making circuit 312 is emptied.

[0089] In another exemplary description, in conjunction with the embodiments of the third solenoid valve assembly 430 and the fourth solenoid valve assembly 440 described above, when the first solenoid valve assembly 410 is in the second mode and the second solenoid valve assembly 420 is in the first mode, if the processing module 50 controls the opening of the first valve V1 and the closing of the second valve V2 and the third valve V3, the detergent solution in the first washing branch can enter the first heating chamber 600b and the second heating chamber 600d to remove dirt in the first heating chamber 600b and the second heating chamber 600d, and the waste liquid can be discharged through the fourth section P2. Subsequently, after closing the fourth solenoid valve assembly 440 so that the second drinking circuit 312 stores a certain amount of detergent solution, the first solenoid valve assembly 410 is driven to the first mode and the second solenoid valve assembly 420 is driven to the second mode, and the first valve V1 and the third valve V3 are closed, and the second valve V2 is opened, so that hot water can enter the second drinking circuit 312 to fully mix the detergent solution and hot water, thereby optimizing the cleaning effect.

[0090] It should be noted that the aforementioned fourth segment P2 and fifth segment P3 can be connected in parallel to the outlet end of the first heating chamber 600b, or the fifth segment P3 and the sixth end P4 can be connected in parallel to the fourth segment P2, etc., without much limitation here. In addition, the first heating chamber 600b and the second heating chamber 600d in this application can refer to the heating chamber of a boiler or the chamber of an instant heating plate, and the beverage making system of this application is not limited to including only the first heating chamber 600b and the second heating chamber 600d.

[0091] In addition to the heating module 60 in the above embodiment being able to connect with the second beverage preparation circuit 312, the first liquid outlet 130b or the third pipe 101c of the liquid dispensing module 10 can also be connected with the second beverage preparation circuit 312.

[0092] In another embodiment, such as Figure 6 as well as Figure 7 As shown, the first liquid outlet 130b (or the outlet end of the third pipe 101c) is connected to the second beverage making circuit 312. In this way, the second beverage making circuit 312 can be washed through the connection between the first washing branch and the second beverage making circuit 312.

[0093] In some embodiments, see back Figure 6The switch module 40 also includes a fifth solenoid valve assembly 450, which is connected between the first solenoid valve assembly 410 and the second drinking circuit 312. Specifically, when the first solenoid valve assembly 410 is in the first mode and the second solenoid valve assembly 420 is in the second mode, and the fifth solenoid valve assembly 450 is in the open state, the first solenoid valve assembly 410 is connected to the second drinking circuit 312 through the fifth solenoid valve assembly 450, so that cold water can be input to clean the second drinking circuit 312, which is convenient for cleaning residual dirt or residual detergent in the second drinking circuit 312 and ensuring drinking performance.

[0094] To further enrich the cleaning scenarios of the solution preparation module 10, in some embodiments, see back Figure 1 The solution mixing module 10 also includes multiple solution mixing devices 100. Each solution mixing device 100 is correspondingly configured with a first switching valve 102 and a first pipeline 101a. The solution mixing chambers 110a of the multiple solution mixing devices 100 are filled with different detergents. The second pipeline 101b is connected to the corresponding outlets of the multiple solution mixing devices 100. Thus, different detergents can be switched by opening and closing the first switching valve 102 to meet different cleaning needs and enrich the cleaning scenarios.

[0095] In one example, the solution preparation module 10 further includes two solution preparation devices 100. Each solution preparation device 100 is correspondingly configured with a first switching valve 102 and a first pipeline 101a. The two solution preparation devices 100 are a first solution preparation device 100c and a second solution preparation device 100d. The solution preparation chamber 110a of the first solution preparation device 100c is used to load a first detergent. The solution preparation chamber 110a of the second solution preparation device 100d is used to load a second detergent. The second pipeline 101b is connected to the outlet of both the first solution preparation device 100c and the second solution preparation device 100d. In one example, the first detergent is an acidic detergent; the second detergent is an alkaline detergent.

[0096] It should be noted that acidic detergents can be any one or a combination of citric acid, sulfamic acid, oxalic acid, etc. Alkaline detergents can be any one or a combination of sodium carbonate, sodium bicarbonate, sodium hydroxide, sodium silicate, etc.

[0097] To make it easier to understand, the following explanation will be based on a real-world beverage preparation scenario.

[0098] In one example, the first beverage-making circuit 311 is used to prepare low-fat beverages, such as coffee or tea. High-fat beverages can be dairy products or chocolate drinks. The first detergent is an acidic detergent. At this time, the first switch valve 102 corresponding to the first liquid preparation device 100c can be opened, the first switch valve 102 corresponding to the second liquid preparation device 100d can be closed, and the second switch valve 103 can be opened to allow the acidic detergent solution to be output.

[0099] In another example, the second beverage preparation circuit 312 is used to prepare a high-fat beverage. The high-fat beverage could be a milk-based beverage or a chocolate beverage, in which case the first switch valve 102 corresponding to the first liquid preparation device 100c can be closed, the first switch valve 102 corresponding to the second liquid preparation device 100d can be opened, and the second switch valve 103 can be opened, allowing the output of an alkaline detergent solution.

[0100] In some embodiments, such as Figure 4 as well as Figure 5 As shown, the liquid dispensing device 100 also includes two first sealing elements 123. The first sealing elements 123 are movably disposed on the support assembly 130. The support assembly 130 has a first liquid inlet 130a and a first liquid outlet 130b, and the first liquid dispensing branch 100a has a second liquid inlet 120a and a second liquid outlet 120b at opposite ends. The two first sealing elements 123 are respectively disposed corresponding to the first liquid inlet 130a and the first liquid outlet 130b, and are spaced apart from the first liquid inlet 130a and the first liquid outlet 130b to form a flow gap 123a. The two first sealing elements 123 are movably extended and retracted within the second liquid inlet 120a and the second liquid outlet 120b, respectively. The first liquid inlet 130a communicates with the second liquid inlet 120a, and the first liquid outlet 130b communicates with the second liquid outlet 120b.

[0101] When the liquid dispensing device 100 and the carrier assembly 130 are in contact, the outer wall of the first sealing member 123 and the inner wall of the first liquid inlet 130a and the inner wall of the first liquid outlet 130b are all spaced apart to form a flow gap 123a, so that the second liquid inlet 120a and the second liquid outlet 120b can communicate with the first liquid inlet 130a and the first liquid outlet 130b respectively through the flow gap 123a, thereby realizing the flow of liquid.

[0102] When the liquid dispensing device 100 and the carrier assembly 130 are spaced apart, the outer wall of the first sealing member 123 can be sealed with the inner wall of the first liquid inlet 130a and the inner wall of the first liquid outlet 130b, so that the second liquid inlet 120a and the second liquid outlet 120b are not connected, thereby ensuring that liquid will not enter the liquid dispensing chamber 110a.

[0103] In this way, the first sealing element 123 can cooperate with the carrier component 130 to ensure that the liquid dispensing branch is not connected when the liquid dispensing container 110 and the carrier component 130 are not installed accurately, thus achieving the sealing performance between the liquid dispensing container 110 and the carrier component 130, thereby avoiding the occurrence of water leakage accidents in the liquid dispensing device 100 and improving the safety of the liquid dispensing device 100.

[0104] In the above embodiments, the first sealing element 123 may be, but is not limited to, an electromagnetic switch switching component 120 drive, or may be other mechanical switching components 120 or other structural drives, without too many restrictions.

[0105] In one embodiment, the first sealing member 123 is provided with an electromagnetic switch assembly. The switching assembly 120 is provided with a sensing body. The sensing body is provided with a plurality of contact points corresponding to the liquid dispensing branches. The electromagnetic switch assembly includes an energized state when the liquid dispensing device 100 is in contact with the contact points, and an de-energized state when the liquid dispensing device 100 and the contact points are separated. When the electromagnetic switch assembly is in the energized state, one liquid dispensing branch in the liquid dispensing device 100 is in a connected state, that is, the aforementioned flow gap 123a exists. When the electromagnetic switch assembly switches from the energized state to the de-energized state, the liquid dispensing branch in the connected state switches from the connected state to the non-connected state, that is, the outer wall of the first sealing member 123 can be sealed with the inner wall of the first liquid inlet 130a and the inner wall of the first liquid outlet 130b.

[0106] Optionally, in one embodiment, combined with Figures 9 to 10 As shown, the dispensing device 100 is movably inserted into the switching assembly 120, allowing the dispensing device 100 to move closer to or further away from the switching assembly 120, switching between mutual contact and separation between the dispensing device 100 and the switching assembly 120. This insertion method improves the stability of the installation and fit between the dispensing device 100 and the switching assembly 120, thereby enhancing the ease of use of the dispensing module 10.

[0107] In another embodiment, combined with Figures 9 to 10 As shown, the switching assembly 120 includes a connector 121 and a mounting bracket 122. The connector 121 is used to engage with the connector 112 of the liquid preparation container 110. The connector 121 is movably connected to the mounting bracket 122. The connector 121 has two insertion portions 121a. A first liquid inlet portion 130a and a first liquid outlet portion 130b are connected and disposed between the mounting bracket 122 and the insertion portions 121a. The connector 121 is used to abut against the liquid preparation container 110. Figure 5 As shown, two first sealing members 123 are movably inserted into the first liquid inlet 130a and the first liquid outlet 130b, respectively. The first liquid inlet 130a and the first liquid outlet 130b are provided with a large hole 1212 and a small hole 1211.

[0108] like Figure 10 As shown, when the liquid preparation container 110 abuts against the connector 121, the liquid preparation container 110 causes the connector 121 to extend and retract relative to the first seal 123 in a direction close to the mounting support 122, so that the connector 121 is in a first position relative to the first seal 123. The outer wall of the first seal 123 can be spaced apart from the inner wall of the small hole 1211 and the inner wall of the large hole 1212 to form a flow gap 123a. At this time, the first liquid inlet 130a and the first liquid outlet 130b can communicate with the second liquid inlet 120a and the second liquid outlet 120b through the flow gap 123a.

[0109] like Figure 9 As shown, when the liquid dispensing device 100 and the connector 121 are spaced apart, the connector 121 can be in a second position relative to the first seal 123, so that the outer wall of the first seal 123 can abut against the inner wall of the small hole 1211 and seal. At this time, the second liquid inlet 120a and the second liquid outlet 120b are not connected, so that the first liquid inlet 130a and the first liquid outlet 130b are not connected to the liquid dispensing chamber 110a.

[0110] Where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0111] The embodiments described above are merely illustrative of several implementation methods of this application, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
