Each first pressure relief position corresponds to one of the aforementioned pressure relief ports. The second valve core can enter or exit each of the aforementioned positions by rotating relative to the first valve core. When the second valve core is in the aforementioned working position, the corresponding outlet is connected to the inlet through a material passage. Correspondingly, when the second valve core is in the first pressure relief position, the corresponding pressure relief port is connected to the inlet through a material passage. Therefore, based on the aforementioned configuration, the valve body device can be used as a component of a beverage machine in practical applications. The inlet of the valve body device can be used to connect to the feeding device of the beverage machine, and the multiple outlets can be used to connect to different flow paths. The second valve core can rotate to different... The working position allows for the connection of the corresponding flow path, distributing materials to the appropriate flow path. This eliminates the need for separate control valves for different flow paths, enabling integrated control of multiple flow paths. It reduces the number of valves used in the flow path system, simplifying the system, reducing its size and weight, improving miniaturization and weight reduction, enhancing installation convenience, and saving production costs. Correspondingly, when the second valve core rotates to the first pressure relief position, the feed inlet can be connected to the pressure relief port via the aforementioned material passage, releasing pressure within the feed inlet and reducing internal pressure in the valve body. The device ensures continuous and stable operation. In the rotation direction of the second valve core, at least a portion of the discharge port is provided with the aforementioned pressure relief port.

[0066] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0067] like Figures 1 to 22 As shown, a valve body device is provided according to a first aspect of the present application, comprising: a first valve core 100 having an inlet 101, a pressure relief port 105, and a plurality of outlets 102; and a second valve core 200 rotatably disposed on the first valve core 100, the second valve core 200 having a feed groove 201 connected to the inlet 101, and the plurality of outlets 102 being arranged at intervals along the rotation direction of the second valve core 200, with at least one set of adjacent outlets 102 spaced apart. The second valve core 200 is provided with a pressure relief port 105. It has a first pressure relief position and multiple working positions. Each working position corresponds to a discharge port 102, and each first pressure relief position corresponds to a pressure relief port 105. When the second valve core 200 is in the working position, the corresponding discharge port 102 is connected to the feed port 101 through the feed groove 201. When the second valve core 200 is in the first pressure relief position, the corresponding pressure relief port 105 is connected to the feed port 101 through the feed groove 201.

[0068] The valve body device provided in this embodiment includes a first valve core 100 and a second valve core 200. The first valve core 100 has an inlet 101, an outlet 102, and a pressure relief port 105. The second valve core 200 is disposed on the first valve core 100 and can rotate relative to the first valve core 100. There are multiple outlets 102, and these outlets are spaced apart along the rotation direction of the second valve core 200. At least one pair of adjacent outlets 102 are connected to a pressure relief port 105. The second valve core 200 has a feed groove 20 communicating with the inlet 101. 1. The second valve core 200 has multiple working positions and a first pressure relief position. Each working position corresponds to a aforementioned discharge port 102, and each first pressure relief position corresponds to a aforementioned pressure relief port 105. The second valve core 200 can enter or leave the aforementioned positions by rotating relative to the first valve core 100. When the second valve core 200 is in the aforementioned working position, the corresponding discharge port 102 is connected to the feed port 101 through the feed groove 201. Correspondingly, when the second valve core 200 is in the first pressure relief position, the corresponding pressure relief port 105 is connected to the feed port 101 through the feed groove 201.

[0069] It is understood that when the second valve core 200 is in any working position, the discharge port 102 corresponding to the aforementioned working position can be connected to the feed port 101 through the feed groove 201, while other discharge ports 102 that do not correspond to the aforementioned working position are cut off from the aforementioned feed port 101.

[0070] Therefore, based on the aforementioned configuration, the valve body device can be used as a component of a beverage machine in practical applications. It is understood that the aforementioned beverage machine can be, but is not limited to, coffee machines, milk tea machines, tea makers, etc.; beverage machines typically include a flow path system within which materials for making beverages can circulate. By controlling the on / off states of different flow paths within the system, the beverage machine can distribute the aforementioned materials to different process components involved in beverage making, thereby executing the corresponding beverage making process. Taking a coffee machine as an example, the aforementioned process components involved in beverage making can include, but are not limited to, brewing devices, foaming devices, dispensing devices, feeding devices, etc., and the aforementioned materials can include, but are not limited to, water, steam, etc.

[0071] Taking the valve body device applied to a beverage machine as an example, the inlet 101 of the valve body device can be used to connect to the feeding device of the beverage machine, and multiple outlets 102 can be used to connect to different flow paths. The second valve core 200 rotates to different working positions, which can conduct the flow path corresponding to the corresponding working position to distribute the material to the corresponding flow path. This avoids configuring corresponding control valves for different flow paths, realizes integrated control of multiple flow paths, reduces the number of valve devices used in the flow path system, simplifies the flow path system, reduces the volume and weight of the flow path system, improves the miniaturization and lightweighting of the beverage machine, enhances the installation convenience of the beverage machine, and saves the production cost of the beverage machine.

[0072] Correspondingly, when the second valve core 200 rotates to the first pressure relief position, the feed port 101 can be connected to the pressure relief port 105 through the aforementioned feed groove 201, thereby releasing the pressure inside the feed port 101, reducing the internal pressure of the valve body device, and ensuring the continuous and stable operation of the valve body device. In addition, in the rotation direction of the second valve core 200, at least a portion of the discharge port 102 is provided with the aforementioned pressure relief port 105. Thus, after the second valve core 200 completes material feeding in the working position, it can be switched from the current working position to the adjacent first pressure relief position by rotating the second valve core 200 to release the pressure inside the feed port 101. In the process of switching between the working position and the first pressure relief position, the stroke of the second valve core 200 can be reduced, the switching efficiency can be improved, and the rapid pressure relief of the feed port 101 can be facilitated. It is also beneficial to improve the accuracy and convenience of the rotation control of the second valve core 200 in practical applications, and further enhance the ease of use of the valve body device.

[0073] It is understandable that the aforementioned pressure relief port 105 can be used to connect to the atmosphere.

[0074] It is understood that the number of the aforementioned pressure relief port 105 can be greater than or equal to one. In practical applications, the number and arrangement of pressure relief ports can be set according to the actual needs of the valve body device. For example, one of the aforementioned pressure relief ports 105 can be arranged between two adjacent discharge ports 102 in each group, or, in some groups, no pressure relief port 105 may be provided between two adjacent discharge ports 102.

[0075] For example, such as Figure 11 As shown, the first valve core 100 may have four discharge ports 102, four pressure relief ports 105, and one feed port 101; Figure 12 and Figure 13 As shown, the second valve core 200 has a feed groove 201 that communicates with the aforementioned feed inlet 101. Figure 13The dashed line with an arrowhead is used to schematically indicate the direction of rotation of the second valve core 200 relative to the first valve core 100; for example... Figures 14 to 21 As shown, the working positions corresponding to the aforementioned four discharge ports 102 are M1, M2, M3 and M4, respectively, and the first pressure relief positions corresponding to the aforementioned four pressure relief ports 105 are N1, N2, N3 and N4, respectively.

[0076] Referring to the example of the valve body device applied to a beverage machine, the beverage machine can be a coffee machine. The coffee machine may include a liquid heating device, a brewing device, a dispensing device, and a milk frothing device. The liquid heating device can be used to heat water and can output steam or heated water. The inlet 101 of the valve body device can be connected to the liquid heating device, meaning the material can include hot water and steam. The dispensing device can be used to dispense liquid and may have a first inlet connected to the brewing device and a second inlet connected to an outlet 102 of the valve body device. Thus, the dispensing device can receive liquid dispensed from the brewing device or from the valve body device. Figures 14 to 21 As shown, the outlet 102 corresponding to the working position M1 of the second valve core 200 can be connected to the second inlet of the aforementioned liquid dispensing device; the aforementioned brewing device can be used to brew coffee powder, and one outlet 102 of the aforementioned valve body device can be connected to the brewing device, such as... Figures 14 to 21 As shown, the working position M2 of the second valve core 200 can be connected to the aforementioned brewing device; the aforementioned foaming device is used to make milk foam, and the two outlets 102 of the valve body device can be connected to the aforementioned foaming device, such as... Figures 14 to 21 As shown, the outlet 102 corresponding to the working position M3 and the outlet 102 corresponding to the working position M4 of the second valve core 200 can both be connected to the aforementioned foaming device.

[0077] Based on the aforementioned settings, such as Figure 14 As shown, in practical applications, when the beverage machine needs to output hot water, the second valve core 200 can be controlled to rotate to the working position M1, so that the hot water output from the liquid heating device can be output through the liquid outlet device, such as... Figure 15 As shown, after the hot water output is completed, the second valve core 200 can be further controlled to rotate from the working position M1 to the first pressure relief position N1 to relieve pressure on the feed port 101.

[0078] like Figure 16 As shown, when it is necessary to brew coffee powder, the second valve core 200 can be rotated to the working position M2 to distribute the hot water output from the liquid heating device to the brewing device, such as... Figure 17 As shown, after hot water is supplied to the brewing unit, the second valve core 200 can be further controlled to rotate from the working position M2 to the first pressure relief position N2 to relieve pressure on the feed inlet 101.

[0079] like Figure 18 As shown, when milk foam needs to be made, the second valve core 200 can be controlled to rotate to the working position M3 to distribute the steam output from the liquid heating device to the foaming device, such as... Figure 17 As shown, after supplying steam for making milk foam to the milk frothing device, the second valve core 200 can be further controlled to rotate from the working position M3 to the first pressure relief position N3 to relieve pressure on the feed inlet 101.

[0080] like Figure 20 As shown, when the foaming device needs cleaning, the second valve core 200 can be controlled to rotate to the working position M4 to distribute the hot water output from the liquid heating device to the foaming device for cleaning. Figure 21 As shown, after the milk frothing device is cleaned, the second valve core 200 can be further controlled to rotate from the working position M4 to the first pressure relief position N4 to relieve pressure on the feed inlet 101. It is easy to understand that, based on the aforementioned configuration of the valve body device, the integration of the beverage machine's flow path system can be improved while ensuring the convenience of pressure relief of the valve body device.

[0081] For example, such as Figure 22 As shown, considering that in practical applications, after connecting to some outlets 102, the inlet 101 will not generate high pressure, so the aforementioned pressure relief port 105 may not be provided between two adjacent outlets 102 in some groups. In conjunction with the aforementioned example, in practical applications, after the valve body completes its work in position M2, that is, after supplying hot water for brewing coffee powder to the brewing device, the pressure inside the inlet is usually low, thus eliminating the need for a pressure relief port 105. Figures 14 to 21 The pressure relief port 105 corresponding to the first pressure relief position N2 shown in the figure, that is, the outlet 102 corresponding to the working position M2 and the outlet 102 corresponding to the working position M3, may not need to be opened between them; correspondingly, after the valve body device completes the operation task of the working position M3, that is, after supplying steam for foaming to the foaming device, the pressure in the inlet 101 is usually relatively small, so it is not necessary to open the outlet 105. Figures 14 to 21 The pressure relief port 105 corresponding to the first pressure relief position N3 shown in the figure, that is, the discharge port 102 corresponding to the working position M3 and the discharge port 102 corresponding to the working position M4, can be without a pressure relief port 105. This reduces the number of openings in the first valve core 100, which helps to reduce the processing cost of the first valve core 100 and improve the structural strength of the first valve core 100.

[0082] It is understood that the above description is merely an illustrative example of the valve body device applied to a beverage machine and is not intended to limit this application. For other devices with flow path systems, such as fluid machinery and hydraulic machinery, the valve body device provided in this application embodiment also has good applicability. When applied to other devices with flow path systems, it also helps to reduce the number of valve components used in the corresponding devices, simplify the flow path system, improve the integration of the flow path system, and further reduce the size, weight, and production cost of the corresponding devices. Further examples based on actual application scenarios will not be provided here.

[0083] like Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figures 12 to 21 As shown, in one feasible embodiment, the second valve core 200 is further formed with a pressure relief groove 203, and the second valve core 200 also has at least one second pressure relief position, each second pressure relief position corresponding to a pressure relief port 105. When the second valve core 200 is in the second pressure relief position, one of the plurality of discharge ports 102 is connected to an adjacent pressure relief port 105 through the pressure relief groove 203.

[0084] In this technical solution, the aforementioned second valve core 200 may also form a pressure relief groove 203 and may have a second pressure relief position corresponding to the aforementioned pressure relief port 105. When the second valve core 200 is in the aforementioned second pressure relief position, one of the multiple discharge ports 102 can be connected to an adjacent pressure relief port 105 through the aforementioned pressure relief groove 203. Based on the aforementioned configuration, after the valve body device completes the operation task of the current working position, the second valve core 200 can be rotated to the second pressure relief position, and the pressure inside the discharge port 102 can be released through the pressure relief port 105, further reducing the internal pressure of the valve body device, which is beneficial to extending the service life of the valve body device and providing a more reliable guarantee for the continuous and stable operation of the valve body device.

[0085] It is understood that when the second valve core 200 is in the second pressure relief position, the pressure relief port 105 connected to the aforementioned pressure relief groove 203 corresponds to the second pressure relief position, and the discharge port 102 connected to the pressure relief port 105 through the pressure relief groove 203 is one of the plurality of discharge ports 102 adjacent to the pressure relief port 105.

[0086] Understandably, the timely depressurization of the outlet 102 after the valve body device completes its current working task can reduce the possibility of residual material seeping out when not in a working position, thus ensuring the cleanliness of the valve body device and further guaranteeing the safe and reliable operation of the beverage machine.

[0087] like Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figures 11 to 21 As shown, in one feasible embodiment, there are multiple pressure relief ports 105, and multiple discharge ports 102 and multiple pressure relief ports 105 are arranged alternately along the rotation direction of the second valve core 200.

[0088] In this technical solution, multiple pressure relief ports 105 can be provided, and the multiple pressure relief ports 105 and multiple discharge ports 102 are alternately arranged along the rotation direction of the second valve core 200. Based on the above arrangement, along the rotation direction of the second valve core 200, each working position can have a first pressure relief position, which greatly facilitates the second valve core 200 to switch from the current working position to the adjacent first pressure relief position to relieve pressure at the feed port 101, reduce the internal pressure of the valve body, and improve the operational reliability of the valve body. Correspondingly, it is also convenient to set the opening parameters of the pressure relief groove 203 so that when the second valve core 200 is in the second pressure relief position, the discharge port is connected to the adjacent pressure relief port 105, which is conducive to further improving the pressure relief convenience of the discharge port 102, thereby providing a more reliable guarantee for maintaining a lower internal pressure in the valve body, and facilitating the timely discharge of residual materials from the valve body, reducing the possibility of material leakage from the valve body, and further improving the cleanliness and safety of the valve body.

[0089] like Figures 3 to 5 , Figure 8 , Figure 11 , Figures 13 to 21 As shown, in one feasible embodiment, the feed inlet 101 is opened in the middle of the first valve core 100, and a plurality of discharge ports 102 are arranged at intervals around the feed inlet 101. The pressure relief port 105 and the discharge ports 102 are located on the same circumference of the first valve core 100. The feed groove 201 is opened radially along the second valve core 200, and the pressure relief groove 203 is opened circumferentially along the second valve core 200. The feed inlet 101 is connected to a portion of the groove of the feed groove 201 near the middle of the second valve core 200.

[0090] In this technical solution, the aforementioned first valve core 100 may have a feed inlet 101 in its center, and multiple discharge outlets 102 may be spaced around the feed inlet 101 circumferentially. That is, the feed inlet 101 and the discharge outlets 102 are spaced apart radially from the first valve core 100. Correspondingly, the aforementioned second valve core 200 may have a material passage groove 201 radially. The feed inlet 101 and a portion of the material passage groove 201 near the center of the second valve core 200 may be interconnected, thereby facilitating the entry of material from the feed inlet 101 into the material passage groove 201 and improving efficiency. The alignment between the first valve core 100 and the second valve core 200 ensures that, during the rotation of the second valve core 200 relative to the first valve core 100, the radially formed feed groove 201 can sequentially pass through each of the aforementioned discharge ports 102. When the feed groove 201 corresponds to the aforementioned discharge port 102, communication is achieved between the feed port 101 and the discharge port 102, distributing material to the flow path corresponding to the discharge port 102. Furthermore, a high degree of alignment between the first valve core 100 and the second valve core 200 also helps to further improve the structural compactness of the valve body device and enhance its miniaturization level.

[0091] Meanwhile, the aforementioned pressure relief port 105 can also be arranged circumferentially around the aforementioned feed inlet 101, and located on the same circumference as the discharge port 102 in the first valve core 100. That is, there is a radial distance between the pressure relief port 105 and the feed inlet 101, and the radial distance between the pressure relief port 105 and the feed inlet 101 is consistent with the radial distance between the discharge port 102 and the feed inlet 101. Thus, during the rotation of the second valve core 200 relative to the first valve core 100, the aforementioned material passage 201 can also pass through the aforementioned pressure relief port 105. When the material passage 201 corresponds to the aforementioned pressure relief port 105, the feed inlet 102 can achieve... The connection between 01 and the pressure relief port 105 facilitates pressure relief at the feed port 101. Furthermore, with the discharge port 102 located on the same circumference as the first valve core 100, the radial dimension of the first valve core 100 can be relatively low, which helps to reduce the volume of the first valve core 100. At the same time, the radial dimension of the feed groove 201 can be set according to the radial interval between the pressure relief port 105 and the feed port 101 or the radial interval between the discharge port 102 and the feed port 101, which helps to reduce the volume of the second valve core 200, thereby further improving the structural compactness of the valve body device and enhancing the miniaturization level of the valve body device.

[0092] Accordingly, the aforementioned pressure relief groove 203 can be opened along the circumference of the second valve core 200, so that during the rotation of the second valve core 200 relative to the first valve core 100, the pressure relief groove 203 can pass through the aforementioned discharge port 102 and the aforementioned pressure relief port 105. When the second valve core 200 is in the aforementioned second pressure relief position, the aforementioned discharge port 102 can be connected to the aforementioned pressure relief port 105 through the aforementioned pressure relief port 105 to relieve pressure at the discharge port 102, reduce the internal pressure of the valve body device, and reduce the amount of material residue in the valve body device.

[0093] It is understood that the radial distance between the pressure relief groove 203 and the center of the second valve core 200 can be consistent with the radial distance between the pressure relief port 105 or the discharge port 102 and the inlet port 101, so that the pressure relief groove 203 can pass through the aforementioned discharge port 102 and pressure relief port 105 during the rotation of the second valve core 200.

[0094] For example, such as Figure 3 As shown, the second valve core 200 can be a disc-shaped structure. In practical applications, the second valve core 200 can rotate around its own axis. Based on the disc-shaped structure, the thickness of the second valve core 200 can be reduced while facilitating its rotation, which is beneficial to further improving the lightweight level of the valve body device. Correspondingly, the aforementioned material passage 201 and pressure relief groove 203 can be opened on one side of the second valve core 200 along the axial direction. The first valve core 100 can also be a disc-shaped structure, and the diameter of the first valve core 100 can be the same as the diameter of the second valve core 200, so as to facilitate the centering arrangement of the first valve core 100 and the second valve core 200 and improve the assembly convenience of the valve body device. The aforementioned inlet 101 can be coaxial with the first valve core 100, and both the aforementioned inlet 101 and the aforementioned outlet 102 are opened along the axial direction of the first valve core 100, which can further facilitate the docking of the first valve core 100 with the second valve core 200.

[0095] In some feasible examples, the aforementioned pressure relief groove 203 can be an arc-shaped groove, with the length direction of the arc-shaped groove aligned with the circumferential direction of the second valve core 200. The two ends of the arc-shaped groove along its length direction can be arc-shaped. Correspondingly, the radius of the aforementioned pressure relief port 105 and the radius of the aforementioned discharge port 102 can both be less than or equal to the radius of the arc-shaped groove's arc-shaped end. This facilitates the matching of the pressure relief groove 203 with the discharge port 102 and the pressure relief port 105, and also reduces stress concentration in the second valve core 200, thereby improving the structural reliability of the second valve core 200 and extending its service life. Correspondingly, the two ends of the aforementioned material passage groove 201 along the radial direction of the second valve core 200 can also be arc-shaped, and the radius of the aforementioned pressure relief port 105 and the radius of the aforementioned discharge port 102 can both be less than or equal to the radius of the arc-shaped end of the aforementioned material passage groove 201.

[0096] like Figure 4 As shown, in one feasible embodiment, the first valve core 100 further forms a first connecting groove 106, a plurality of second connecting grooves 107 and a pressure relief channel 108, wherein the first connecting groove 106 is arranged around the feed inlet 101, one end of each second connecting groove 107 is connected to a pressure relief port 105 and the other end is connected to the first connecting groove 106, and one end of the pressure relief channel 108 is connected to one of the plurality of pressure relief ports 105.

[0097] In this technical solution, the aforementioned first valve core 100 may also include a first connecting groove 106, a second connecting groove 107, and a pressure relief channel 108. The first connecting groove 106 is arranged around the aforementioned feed inlet 101. There are multiple second connecting grooves 107, and each pressure relief port 105 is connected to the first connecting groove 106 through a second connecting groove 107. Thus, multiple pressure relief ports 105 can be interconnected through the first connecting groove 106 and the second connecting groove 107. One end of the pressure relief channel 108 is connected to multiple pressure relief ports. One end of 105 is used to connect to the atmosphere. Based on the aforementioned arrangement, the second valve core 200 can be depressurized through the aforementioned depressurization channel 108 when it is in various depressurization positions. This can further improve the integration of the depressurization path of the valve body device, improve the structural compactness of the valve body device, and facilitate the release of internal pressure of the valve body device. At the same time, it helps to reduce the number of through holes in the first valve core 100, which helps to further ensure the structural strength of the first valve core 100 and extend the service life of the first valve core 100.

[0098] It is understood that one of the aforementioned pressure relief ports 105 is directly connected to the aforementioned pressure relief channel 108, while the remaining pressure relief ports 105 are indirectly connected to the aforementioned pressure relief channel 108 through the first connecting groove 106 and the second connecting groove 107. Thus, when processing the first valve core 100, the aforementioned pressure relief channel 108 and the aforementioned pressure relief port 105 directly connected to the aforementioned pressure relief channel 108 can be formed by opening through holes in the first valve core 100. The remaining pressure relief ports 105 can be blind holes with openings facing the second valve core 200, thereby reducing the number of through holes opened on the first valve core 100.

[0099] like Figure 11 As shown, in one feasible embodiment, a plurality of discharge ports 102 are arranged at preset intervals θ around the circumference of the feed inlet 101, and the pressure relief port 105 is arranged at intervals of 0.5 times the preset interval angle θ with the adjacent discharge port 102. The preset interval angle θ satisfies:

[0100] θ≤360° / a

[0101] Where θ is the preset interval angle and a is the number of discharge ports.

[0102] In this technical solution, when multiple discharge ports 102 are opened at intervals along the circumference of the feed inlet 101, a preset interval angle θ is maintained between adjacent discharge ports 102. Thus, when the second valve core 200 switches between working positions, the rotation angle can be an integer multiple of the preset interval angle θ. This is beneficial to improving the convenience and accuracy of the rotation control of the second valve core 200, reducing the error when the second valve core 200 switches between working positions, and providing further assurance for the valve body device to reliably perform pressure relief and flow path on / off control.

[0103] Meanwhile, when a pressure relief port 105 needs to be opened between two adjacent discharge ports 102, the pressure relief port 105 can be arranged at a distance of 0.5 times the preset interval angle θ from the adjacent discharge port 102. Thus, when switching between the first pressure relief position and the working position, the second valve core 200 can also rotate at a relatively fixed rotation angle, further ensuring the stable and reliable execution of the pressure relief process.

[0104] It is understandable that, such as Figure 11 As shown, the aforementioned preset interval angle θ can be the angle of the central angle with the axis position of the first valve core 100 as the center, and the two sides of the aforementioned central angle pass through the axes of two adjacent discharge ports 102 respectively.

[0105] For example, such as Figure 11 As shown, the valve body device can have 4 discharge ports 102. The preset interval angle θ between two adjacent discharge ports 102 can be less than or equal to 90°. Considering the uniformity of the distribution of discharge ports 102 along the circumference of the first valve core 100, the preset interval angle θ can be set to be equal to 90°.

[0106] In some feasible examples, the valve body device may also include a drive unit, which may be a motor or other drive device capable of outputting rotation. The drive unit is connected to the second valve core 200 and is used to drive the second valve core 200 to rotate relative to the first valve core 100, thereby improving the ease of use of the valve body device. For example, the aforementioned drive unit may be a stepper motor. Stepper motors can output small-angle rotation and have high stopping flexibility, which is beneficial to improving the rotational stability of the second valve core 200 and improving the action accuracy of the second valve core 200 during position switching. At the same time, based on the aforementioned preset interval angle θ setting, it is also beneficial to improve the convenience of output control of the drive unit in practical applications.

[0107] It is understandable that, when the drive unit is the aforementioned stepper motor, 0.5 times the aforementioned preset interval angle θ can be an integer multiple of the step angle of the stepper motor, that is, the aforementioned preset interval angle θ can be an even multiple of the step angle of the stepper motor.

[0108] like Figure 12 As shown, in one feasible embodiment, along the circumference of the second valve core 200, the feed groove 201 and the pressure relief groove 203 are arranged at a distance of 0.5 times the preset interval angle θ, and the pressure relief groove 203 is located on the side of the feed groove 201 away from the rotation direction of the second valve core 200.

[0109] In this technical solution, along the circumference of the second valve core 200, the material passage 201 and the pressure relief groove 203 are arranged at a distance of 0.5 times the preset interval angle θ, and the pressure relief groove 203 is located on the side of the material passage 201 away from the rotation direction of the second valve core 200. Based on the above arrangement, after the valve body device completes the operation task of the current working position, the second valve core 200 can be rotated along the rotation direction by 0.5 times the aforementioned preset interval angle, so that the feed port 101 can be connected to the pressure relief port 105 adjacent to the discharge port 102 corresponding to the current working position through the material passage 201, that is, the second valve core 200 enters the first pressure relief position to realize the pressure relief of the feed port 101.

[0110] When the second valve core 200 rotates from the aforementioned current working position to the adjacent first pressure relief position, the pressure relief groove 203 can be simultaneously located at the discharge port 102 corresponding to the aforementioned current working position. By setting the opening length of the pressure relief groove 203 along the circumference of the second valve core 200, for example, when the pressure relief groove 203 is an arc-shaped groove, the central angle corresponding to the aforementioned arc-shaped groove can be set to be greater than or equal to 0.5 times the preset interval angle and less than the preset interval angle. When there is also a pressure relief port 105 on the side of the discharge port 102 corresponding to the aforementioned current working position away from the aforementioned rotation direction, the discharge port 102 corresponding to the aforementioned current working position can be depressurized through the pressure relief groove 203. That is, a portion of the second pressure relief position can coincide with the first pressure relief position, which facilitates the synchronous depressurization of the inlet 101 and the outlet 102 after the valve body device completes the operation task of the current working position. This is beneficial to improving the timeliness of depressurization of the outlet 102 and provides further assurance for the stable and reliable operation of the valve body device.

[0111] like Figures 1 to 10As shown, in one feasible embodiment, the valve body device further includes: a base portion 300; a bearing portion 400 disposed on the base portion 300, and a second valve core portion 200 connected to the bearing portion 400; a connector portion 500 disposed on the first valve core portion 100, the connector portion 500 forming a feed flow path 501, a pressure relief flow path 505 and a plurality of discharge flow paths 502, the feed flow path 501 being connected to the feed port 101, each discharge flow path 502 being connected to a discharge port 102, and each pressure relief port 105 being connected to the pressure relief flow path 505.

[0112] In this technical solution, the valve body device may further include a base portion 300, a bearing portion 400, and a connector portion 500. The aforementioned first valve core portion 100 and the aforementioned second valve core portion 200 may be disposed between the aforementioned base portion 300 and the aforementioned connector portion 500. The first valve core portion 100 may be disposed in the aforementioned connector portion 500, and the second valve core portion 200 may be connected to the aforementioned base portion 300 via the aforementioned bearing portion 400 to improve the smoothness of rotation of the second valve core portion 200. The connector portion 500 may form an inlet flow path 501 and multiple outlet flow paths 502. The inlet 101 of the first valve core portion 100 may be connected to the aforementioned inlet... The material flow path 501 is connected, and the outlet 102 of the second valve core 200 can be connected to the aforementioned outlet flow path 502 one by one. Based on the aforementioned configuration, in practical applications, the valve body device can be connected to an external device through the connector 500 to facilitate the valve body device to receive and dispense materials. At the same time, the connector 500 also forms a pressure relief flow path 505. Each of the aforementioned pressure relief ports 105 can be connected to the aforementioned pressure relief flow path 505, and the end of the pressure relief flow path 505 away from each pressure relief port 105 is used to connect to the atmosphere. Thus, multiple pressure relief ports 105 can release pressure through the pressure relief flow path 505, improving the integration of the pressure relief path of the valve body device.

[0113] It is understood that when the first valve core 100 has the aforementioned pressure relief channel 108, the end of the aforementioned pressure relief channel 108 that is away from the pressure relief port 105 is connected to the aforementioned pressure relief flow path 505.

[0114] like Figure 3 As shown, in one feasible embodiment, a first protrusion 410 is formed on the periphery of the bearing portion 400, a first groove 310 is formed on the base portion 300, and the first protrusion 410 is inserted into the first groove 310; and / or a second protrusion is formed on the connector portion 500, a second groove 110 is formed on the periphery of the first valve core portion 100, and the second protrusion is inserted into the second groove 110.

[0115] In this technical solution, the aforementioned bearing portion 400 may have a first protrusion 410, which is located on the periphery of the bearing portion 400. The aforementioned base portion 300 has a first groove 310 that is adapted to the first protrusion 410. The first protrusion 410 is inserted into the first groove 310. Based on the matching relationship between the first protrusion 410 and the first groove 310, the bearing portion 400 can be circumferentially fixed, thereby improving the positional stability of the bearing portion 400 and providing a reliable guarantee for improving the rotational smoothness of the second valve core portion 200.

[0116] In this technical solution, the aforementioned first valve core 100 may have a second groove 110, which is located on the periphery of the second valve core 200. The aforementioned connector 500 has a second protrusion that matches the second groove 110. The second protrusion is inserted into the second groove 110. Based on the matching relationship between the second groove 110 and the second protrusion, the first valve core 100 can be circumferentially fixed, preventing the first valve core 100 from circumferentially moving under the drive of the second valve core 200. This helps to ensure the positional stability of the second valve core 200, thereby improving the operational stability of the valve body device.

[0117] It is understood that the valve body device may be provided with the aforementioned first protrusion 410, first groove 310, second protrusion and second groove 110 at the same time, so as to further ensure the overall operational reliability of the valve body device.

[0118] In one feasible embodiment, the valve body device further includes a sealing part 600 disposed between the first valve core part 100 and the connector part 500. The sealing part 600 has a first through hole 601, a third through hole 603 and a plurality of second through holes 602. The first through hole 601 is arranged corresponding to the feed inlet 101, each second through hole 602 is arranged corresponding to a discharge outlet 102, and each third through hole 603 is arranged corresponding to a pressure relief port 105.

[0119] In this technical solution, the valve body device may further include a sealing portion 600 disposed between the first valve core portion 100 and the connector portion 500. The sealing portion 600 can be used to seal the connection gap between the first valve core portion 100 and the connector portion 500, thereby reducing the possibility of material leakage through the first valve core portion 100 and the connector portion 500, which is beneficial to further improve the cleanliness of the valve body device and reduce material loss. The sealing portion 600 is formed with a first through hole 601, a third through hole 603 and a plurality of second through holes 602. The first through hole 601 is connected to the feed port 101 of the first valve core 100. The second through hole 602 is connected to the discharge port 102 of the first valve core 100. The number of third through holes 603 can be the same as the number of pressure relief ports 105, and the third through holes 603 are connected to the pressure relief ports 105 of the first valve core 100. Thus, the valve body device can ensure material passage and smooth execution of the pressure relief process while sealing the connection gap between the first valve core 100 and the connector 500 with the sealing part 600.

[0120] like Figure 3 As shown, in one feasible embodiment, the connector portion 500 has a first limiting structure formed on the side facing the sealing portion 600, the sealing portion 600 has a second limiting structure 610, and the first limiting structure and the second limiting structure 610 are adapted to each other; and / or the first valve core portion 100 has a third limiting structure formed on the side facing the sealing portion 600, the sealing portion 600 has a fourth limiting structure, and the third limiting structure and the fourth limiting structure are adapted to each other.

[0121] In this technical solution, the aforementioned connector portion 500 and the aforementioned sealing portion 600 may respectively form a first limiting structure and a second limiting structure 610. The shape of the aforementioned first limiting structure is adapted to the shape of the aforementioned second limiting structure 610. When the sealing portion 600 is connected to the aforementioned connector portion 500, the aforementioned first limiting structure and the aforementioned second limiting structure 610 can be mated with each other to fix the position of the sealing portion 600 relative to the connector portion 500, thereby ensuring the sealing effect between the sealing portion 600 and the connector portion 500.

[0122] In this technical solution, the aforementioned first valve core 100 and the aforementioned sealing part 600 can be respectively formed with a third limiting structure and a fourth limiting structure. The shape of the aforementioned third limiting structure is adapted to the shape of the aforementioned fourth limiting structure. When the sealing part 600 is connected to the aforementioned first valve core 100, the aforementioned third limiting structure and the aforementioned fourth limiting structure can dock with each other to fix the position of the sealing part 600 relative to the first valve core 100, thereby ensuring the sealing effect between the sealing part 600 and the first valve core 100.

[0123] It is understandable that the specific forms of the aforementioned limiting structures can be diverse, such as... Figure 3 As shown, the aforementioned first limiting structure can be one of a protrusion structure and a groove structure. Correspondingly, the second limiting structure 610 can be another of a protrusion structure and a groove structure. The aforementioned protrusion structure and the aforementioned groove structure have mutually compatible shapes. The third limiting structure and the fourth limiting structure are similar.

[0124] According to a second aspect of the embodiments of this application, a beverage machine is provided, comprising: a valve body device as described in any of the first aspects above, wherein a plurality of outlets 102 include a first liquid outlet, a second liquid outlet, a steam outlet and a cleaning outlet; a brewing device, wherein the first liquid outlet is connected to the brewing device; a liquid outlet device having a first liquid inlet and a second liquid inlet, wherein the output end of the brewing device is connected to the first liquid inlet and the second liquid outlet is connected to the second liquid inlet; and a foaming device, wherein both the steam outlet and the cleaning outlet are connected to the foaming device.

[0125] The beverage machine provided in this application includes a brewing device, a dispensing device, a foaming device, and a valve body device as described in any of the first aspects above. The brewing device can be connected to the first dispensing port of the valve body device, the first inlet of the dispensing device can be connected to the output end of the brewing device, the second inlet of the dispensing device can be connected to the second dispensing port of the valve body device, and the foaming device can be connected to the steam port and the cleaning port of the valve body device. Thus, during use, by switching the working position of the aforementioned second valve core 200, the material in the valve body device can be distributed to the brewing device, the dispensing device, or the foaming device. This ensures that the brewing device, the dispensing device, and the foaming device can receive materials during the beverage making process, while reducing the number of valve components used in the beverage machine. This is beneficial for improving the miniaturization and lightweighting of the beverage machine, simplifying the flow path system of the beverage machine, facilitating the control of the overall volume and production cost of the beverage machine, and improving the installation convenience of the beverage machine.

[0126] It is understood that the valve body device provided in this application embodiment includes a first valve core portion 100 and a second valve core portion 200. The first valve core portion 100 has an inlet 101, an outlet 102, and a pressure relief port 105. The second valve core portion 200 is disposed on the first valve core portion 100 and can rotate relative to the first valve core portion 100. There are multiple outlets 102 and multiple pressure relief ports 105, and these are alternately arranged along the rotation direction of the second valve core portion 200. The second valve core portion 200 has a feed groove 20 communicating with the inlet 101. 1. The second valve core 200 has multiple working positions and multiple pressure relief positions. Each working position corresponds to a aforementioned discharge port 102, and each pressure relief position corresponds to a aforementioned pressure relief port 105. The second valve core 200 can enter or leave the aforementioned positions by rotating relative to the first valve core 100. When the second valve core 200 is in the aforementioned working position, the corresponding discharge port 102 is connected to the feed port 101 through the feed groove 201. Correspondingly, when the second valve core 200 is in the pressure relief position, the corresponding pressure relief port 105 is connected to the feed port 101 through the feed groove 201.

[0127] It is understood that when the second valve core 200 is in any working position, the discharge port 102 corresponding to the aforementioned working position can be connected to the feed port 101 through the feed groove 201, while other discharge ports 102 that do not correspond to the aforementioned working position are cut off from the aforementioned feed port 101.

[0128] It is understandable that the aforementioned beverage machine can be used as a coffee machine in practical applications, the aforementioned liquid dispensing device can be used to dispense liquid, the aforementioned brewing device can be used to brew coffee powder, and the aforementioned foaming device can be used to make milk foam.

[0129] In some feasible examples, the beverage machine may also include a feeding device, which may be a liquid heating device that can be used to heat water and output steam or heated water. The inlet 101 of the valve body device may be connected to the liquid heating device, so that the beverage machine can supply hot water or steam to the brewing device, liquid dispensing device or foaming device through the valve body device.

[0130] For example, such as Figures 11 to 21As shown, the first valve core 100 may have four discharge ports 102, four pressure relief ports 105, and one feed port 101. The second valve core 200 has a feed trough 201 connected to the aforementioned feed port 101. The aforementioned four discharge ports 102 may be a first liquid outlet, a second liquid outlet, a steam port, and a cleaning port, respectively. The working position corresponding to the first liquid outlet is M2, the working position corresponding to the second liquid outlet is M1, the working position corresponding to the steam port is M3, and the working position corresponding to the cleaning port is M4. The working positions corresponding to the aforementioned four pressure relief ports 105 are N1, N2, N3, and N4, respectively. The second outlet corresponding to the working position M1 of the second valve core 200 can be connected to the second inlet of the aforementioned liquid outlet device; the first outlet corresponding to the working position M2 of the second valve core 200 can be connected to the aforementioned brewing device; the steam port corresponding to the working position M3 of the second valve core 200 and the cleaning port corresponding to the working position M4 can both be connected to the aforementioned foaming device, and the liquid inlet can be connected to the aforementioned liquid heating device.

[0131] Based on the aforementioned settings, such as Figure 14 As shown, in practical applications, when the beverage machine needs to output hot water, the second valve core 200 can be controlled to rotate to the working position M1, so that the hot water output from the liquid heating device can be output through the liquid outlet device, such as... Figure 15 As shown, after the hot water output is completed, the second valve core 200 can be further controlled to rotate from the working position M1 to the pressure relief position N1 to relieve pressure on the feed port 101.

[0132] like Figure 16 As shown, when it is necessary to brew coffee powder, the second valve core 200 can be rotated to the working position M2 to distribute the hot water output from the liquid heating device to the brewing device, such as... Figure 17 As shown, after hot water is supplied to the brewing unit, the second valve core 200 can be further controlled to rotate from the working position M2 to the pressure relief position N2 to relieve pressure on the feed inlet 101.

[0133] like Figure 18 As shown, when milk foam needs to be made, the second valve core 200 can be controlled to rotate to the working position M3 to distribute the steam output from the liquid heating device to the foaming device, such as... Figure 17 As shown, after supplying steam for making milk foam to the milk frothing device, the second valve core 200 can be further controlled to rotate from the working position M3 to the pressure relief position N3 to relieve pressure on the feed inlet 101.

[0134] like Figure 20 As shown, when the foaming device needs cleaning, the second valve core 200 can be controlled to rotate to the working position M4 to distribute the hot water output from the liquid heating device to the foaming device for cleaning. Figure 21As shown, after the milk frothing device is cleaned, the second valve core 200 can be further controlled to rotate from the working position M4 to the pressure relief position N4 to relieve pressure on the feed inlet 101.

[0135] It is easy to understand that, based on the aforementioned configuration of the valve body device, the integration of the beverage machine's flow path system can be improved while ensuring the convenience of pressure relief of the valve body device.

[0136] Furthermore, since the beverage machine provided in this application embodiment includes a valve body device as described in any of the first aspects above, it possesses all the beneficial effects of such a valve body device, which will not be elaborated here.
