[0073] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0074] like Figures 1 to 17As shown, according to the first aspect of the embodiment of the present application, a valve body device is proposed, comprising: a first valve core part 100, the first valve core part 100 is formed with an air inlet 103, an air outlet 104, a feed port 101 and a plurality of discharge ports 102; a second valve core part 200, rotatably arranged on the first valve core part 100, the second valve core part 200 is formed with a feed groove 201 and an air groove 202, the feed groove 201 is connected to the feed port 101, and the plurality of discharge ports 102 are arranged along the second valve core part The second valve core portion 200 is arranged at intervals in the rotation direction, and the second valve core portion 200 has a plurality of working positions, each working position corresponds to an outlet port 102, and when the second valve core portion 200 is in the working position, the corresponding outlet port 102 is connected to the feed port 101 through the gas groove 201; wherein, one of the plurality of working positions is a gas injection station, and when the second valve core portion 200 is in the gas injection station, the gas inlet port 103 is connected to the gas outlet port 104 through the gas groove 202.

[0075] The valve body device provided in the embodiment of the present application includes a first valve core part 100 and a second valve core part 200, wherein the first valve core part 100 is formed with a feed port 101 and a discharge port 102 to facilitate the flow of materials into or out of the valve body device, the second valve core part 200 is arranged on the first valve core part 100, and is formed with a feed slot 201 connected to the feed port 101, the second valve core part 200 can rotate relative to the first valve core part 100, the number of the discharge ports 102 is multiple, and the multiple discharge ports 102 are arranged at intervals on the first valve core part 10 along the rotation direction of the second valve core part 200 0, so that during the rotation of the second valve core part 200, the aforementioned material passage trough 201 is connected with different discharge ports 102 in sequence. Accordingly, the second valve core part 200 has a plurality of working positions, and each aforementioned working position corresponds to one aforementioned discharge port 102. When the second valve core part 200 is rotated to the aforementioned working position, the discharge port 102 corresponding to the current working position of the second valve core part 200 can be connected to the feed port 101 through the material passage trough 201, so that the material flowing into the valve body device through the feed port 101 can further flow to the discharge port 102 and be discharged from the valve body device.

[0076] At the same time, the first valve core portion 100 is also formed with an air inlet 103 and an air outlet 104, and the second valve core portion 200 is also formed with an air passage groove 202. One of the multiple aforementioned working positions is a gas injection station. Accordingly, when the second valve core portion 200 is in the aforementioned gas injection station, the aforementioned air inlet 103 and the aforementioned air inlet 103 can be connected through the aforementioned air passage groove 202.

[0077] It should be noted that Figure 8 The dashed line with an arrow in the figure is used to schematically indicate the rotation direction of the second valve core part 200 relative to the first valve core part 100; Figures 9 to 17M1, M2, M3 and M4 are used to schematically represent the aforementioned working positions.

[0078] It is understandable that if Fig. 9 , Fig.11 , Fig.13 , Fig.14 and Fig.16 As shown, 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 slot 201, and other discharge ports 102 that do not have a corresponding relationship with the aforementioned working position are terminated at the aforementioned feed port 101; Fig.10 , Fig.12 , Fig.15 and Fig.17 As shown, when the second valve core portion 200 is not in the working position, the feed port 101 and any of the discharge ports 102 are in a cut-off state.

[0079] Therefore, based on the above-mentioned settings, in actual applications, the valve body device can be used as a component of a beverage machine. It can be understood that the above-mentioned beverage machine can be but not limited to a coffee machine, a milk tea machine, a tea machine, a sparkling water machine, etc.; the beverage machine usually includes a flow system, and the materials used to make beverages can flow in the above-mentioned flow system. By controlling the on-off of different flow paths in the flow system, the beverage machine can distribute the above-mentioned materials to different process components involved in beverage production, so as to perform the corresponding beverage production process; taking the above-mentioned beverage machine as a coffee machine as an example, the above-mentioned process components involved in beverage production can include but are not limited to a brewing device, a foaming device, a liquid outlet device, a feeding device, an air supply device, etc., and the above-mentioned materials can be but not limited to water, steam, air, etc.

[0080] Taking the application of the valve body device in a beverage machine as an example, the feed port 101 of the valve body device can be used to connect to the feeding device of the beverage machine, and the multiple discharge ports 102 can be used to connect different flow paths respectively. The driving unit can drive the second valve core portion 200 to rotate to different working positions, thereby connecting the flow paths corresponding to the corresponding working positions to distribute the materials to the corresponding flow paths, thereby avoiding the need to configure corresponding control valves for different flow paths, realizing integrated control of multiple flow paths, reducing the number of valve devices used in the flow path system, simplifying the flow path system, reducing the volume and mass of the flow path system, and improving the miniaturization and lightweight level of the beverage machine, improving the installation convenience of the beverage machine, and saving the production cost of the beverage machine.

[0081] At the same time, the air inlet 103 of the valve body device can also be used to connect to the air supply device of the beverage machine, so that in actual application, the valve body device can also be used to control the gaseous material distribution of the beverage machine, and when the second valve core portion 200 is in the aforementioned air injection station, the aforementioned feed port 101 can also be connected to one of the multiple discharge ports 102 through the material chute 201, so that the valve body device can realize synchronous control of the distribution of different types of materials. On the one hand, it is beneficial to improve the material distribution efficiency of the beverage machine and improve the beverage making efficiency of the beverage machine; on the other hand, it can also enhance the adaptability of the valve body device to beverage machines that have the need to synchronously supply different materials, further expanding the scope of application of the valve body device.

[0082] Taking the valve body device further applied to a coffee machine as an example, the coffee machine may include a feeding device, an air supply device, a brewing device, a liquid discharge device and a foaming device, such as Figures 5 to 17 As shown, the valve body device may have one aforementioned feed port 101, four aforementioned discharge ports 102, one aforementioned air inlet 103 and one aforementioned air outlet 104, as shown in FIG. Figures 9 to 17 As shown, the working positions corresponding to the four aforementioned discharge ports 102 are M1, M2, M3 and M4, respectively. Fig.13 As shown, the working position M3 can be the aforementioned gas injection station. Correspondingly, the aforementioned feeding device can be a liquid heating device for heating water and can be used to output steam or heated water. The feed port 101 of the valve body device can be connected to the aforementioned liquid heating device, that is, the aforementioned material can include hot water and steam; the aforementioned liquid outlet device can be used to output liquid, and can have a first liquid inlet end connected to the aforementioned brewing device and a second liquid inlet end connected to an outlet 102 of the aforementioned valve body device, so that the liquid outlet device can receive liquid output by the brewing device or liquid output by the valve body device, and the outlet 102 corresponding to the aforementioned working position M1 can be The second liquid inlet end of the aforementioned liquid outlet device is used to be connected; the aforementioned brewing device can be used to brew coffee powder, and one of the discharge ports 102 of the aforementioned valve body device can be connected to the brewing device, and the working position M2 of the second valve core part 200 can be connected to the aforementioned brewing device; the aforementioned frothing device is used to make milk froth. It can be understood that some coffee drinks will contain milk froth, and air and steam are often required when frothing, and the frothing device often needs to be cleaned in time after the milk froth is made, so the air outlet 104 and the two discharge ports 102 of the valve body device can be connected to the aforementioned frothing device, such as Figures 9 to 17As shown, the discharge port 102 corresponding to the working position M3 of the second valve core portion 200 and the discharge port 102 corresponding to the working position M4 can both be connected to the aforementioned foaming device, wherein the discharge port 102 corresponding to the working position M3 can be used to output steam required for foaming to the foaming device, the discharge port 102 corresponding to the working position M4 can be used to output hot water for cleaning to the foaming device, and the air outlet 104 can be used to output air required for foaming to the foaming device; the aforementioned air supply device can be used to supply the air required for foaming to the foaming device, so that the air inlet 103 of the valve body device can be connected to the aforementioned air supply device.

[0083] Based on the above settings, Fig. 9 As shown, when the beverage machine needs to output hot water, the second valve core part 200 can be controlled to rotate to the working position M1 to directly output the hot water output by the liquid heating device through the liquid outlet device; Fig.11 As shown, when it is necessary to brew coffee powder, the second valve core portion 200 can be controlled to rotate to the working position M2 to distribute the hot water output by the liquid heating device to the brewing device; Fig.13 As shown, when it is necessary to make milk froth, the second valve core part 200 can be controlled to rotate to the working position M3 to distribute the steam output by the liquid heating device to the frothing device. At the same time, since the working position M3 is the aforementioned gas injection station, the gas outlet 104 can be connected to the gas inlet 103 through the gas groove 202 at the same time to distribute the air output by the gas supply device to the frothing device. Then, in the process of making coffee containing milk froth, the distribution control of steam and air can be synchronously realized through the valve body device, which is conducive to further simplifying the flow path between the gas supply device, the liquid heating device and the milk frothing device, reducing the use of valve components of the coffee machine, improving the miniaturization and lightweight level of the coffee machine, and reducing the production cost of the coffee machine; Fig.16 As shown, when the frothing device needs to be cleaned, the second valve core portion 200 can be controlled to rotate to the working position M4 to distribute the hot water output by the liquid heating device to the frothing device to clean the milk frothing device.

[0084] It is understandable that the above description is only an exemplary description based on the application of the valve body device to a beverage machine or a coffee machine, and is not intended to limit the present application. For other equipment with a flow system, such as fluid machinery, hydraulic machinery, etc., the valve body device provided in the embodiment of the present application also has good applicability, and when applied to other equipment with a flow system, it is also helpful to reduce the use of valve components of the corresponding equipment, simplify the flow system of the corresponding equipment, improve the integration of the flow system, and facilitate the further reduction of the volume, weight, and production cost of the corresponding equipment. No further examples will be given here in combination with actual application scenarios.

[0085] like Figures 3 to 6 , Figures 8 to 17As shown, in a feasible embodiment, the first valve core portion 100 is also formed with at least one pressure relief port 105, and a pressure relief port 105 is arranged between at least one group of two adjacent discharge ports 102; the second valve core portion 200 also has at least one first pressure relief position, each first pressure relief position corresponds to a pressure relief port 105, and when the second valve core portion 200 is in the first pressure relief position, the corresponding pressure relief port 105 is connected to the feed port 101 through the feed trough 201.

[0086] In this technical solution, the first valve core portion 100 may also be formed with a pressure relief port 105, and the pressure relief port 105 is used to connect to the atmosphere. Correspondingly, the second valve core portion 200 also has a first pressure relief position corresponding to the pressure relief port 105. When the second valve core portion 200 is in the first pressure relief position, the pressure relief port 105 corresponding to the first pressure relief position of the second valve core portion 200 may be connected to the feed port 101 through the material transfer groove 201. Therefore, during use, after the valve body device completes the operating task of the current working position, the second valve core portion 200 can be rotated to the first pressure relief position, and the pressure inside the feed port 101 can be released through the pressure relief port 105, which is beneficial to extend the service life of the valve body device, reduce the internal pressure of the valve body device, and provide a guarantee for the continuous and stable operation of the valve body device.

[0087] At the same time, the number of the aforementioned pressure relief ports 105 is at least one, and one aforementioned pressure relief port 105 is arranged between at least one group of adjacent two aforementioned discharge ports 102, so that in the rotation direction of the second valve core portion 200, the pressure relief port 105 can be adjacent to the aforementioned discharge port 102, which is convenient for the second valve core portion 200 to switch between the working position and the first pressure relief position, and is beneficial for the valve body device to switch to the adjacent first pressure relief position more quickly after completing the operating task of the current working position, so that the feed port 101 is connected to the pressure relief port 105 through the feed chute 201, and the pressure of the feed port 101 is relieved, thereby avoiding the valve body device from maintaining a high internal pressure after work, and improving the pressure relief execution efficiency of the valve body device.

[0088] It is understandable that the valve body device promptly releases pressure at the feed port 101 after completing the operating task at the current working position, which can also reduce the possibility of residual material in the valve body device leaking out in the non-working position, which is beneficial to ensure the cleanliness of the valve body device and further ensure the safe and reliable operation of the beverage machine.

[0089] For example, Figure 5 , Figure 6 and Figure 8 As shown, the specific number and position of the pressure relief ports 105 can be set in combination with the actual needs of the valve body device; Figure 5 and Figure 8As shown, in combination with the example of the valve body device being applied to a coffee machine, the first valve core part 100 can be provided with a pressure relief port 105 between the discharge port 102 corresponding to the working position M1 and the discharge port 102 corresponding to the working position M2 along the rotation direction of the second valve core part 200, that is, Figures 9 to 17 A pressure relief port 105 is provided corresponding to the first pressure relief position N1, and a pressure relief port 105 is provided between the discharge port 102 corresponding to the working position M4 and the discharge port 102 corresponding to the station position M1, that is, Figures 9 to 17 As for the pressure relief port 105 corresponding to the first pressure relief position N2, it can be understood that after the coffee machine directly outputs hot water through the liquid outlet device or supplies the hot water required for cleaning to the foaming device, there is a relatively high pressure in the feed port 101. Therefore, based on the above-mentioned setting, the second valve core part 200 can be controlled to switch to the adjacent first pressure relief position along the rotation direction to release the pressure inside the valve body device. After the valve body device completes the working task of the working position M2 or the working position M3, the pressure in the feed port 101 is relatively small, so the pressure relief port 105 may not be opened between the working position M2 and the working position M3, and the pressure relief port 105 may not be opened between the working position M3 and the working position M4, thereby reducing the number of openings of the first valve core part 100, ensuring the sealing and structural reliability of the first valve core part 100; accordingly, as Figure 6 As shown, if there is a higher pressure in the feed port 101 after the valve body device completes the operating task at each working position, the first valve core portion 100 can open a pressure relief port 105 between any two adjacent discharge ports 102 along the rotation direction of the second valve core portion 200, so that the second valve core portion 200 can rotate more quickly to the adjacent first pressure relief position to relieve the pressure at the feed port 101 after completing the operating task at any working position.

[0090] It is understandable that the valve body device promptly releases pressure at the feed port 101 after completing the operating task at the current working position, which can also reduce the possibility of residual material in the valve body device leaking out in the non-working position, which is beneficial to ensure the cleanliness of the valve body device and further ensure the safe and reliable operation of the beverage machine.

[0091] like Figure 3 , Figures 7 to 17 As shown, in a feasible embodiment, the second valve core portion 200 is also formed with a pressure relief groove 203, and the second valve core portion 200 also has at least one second pressure relief position, each second pressure relief position corresponds to a pressure relief port 105, and when the second valve core portion 200 is in the second pressure relief position, one of the multiple discharge ports 102 is connected to an adjacent pressure relief port 105 through the pressure relief groove 203.

[0092] In this technical solution, the second valve core portion 200 may also be formed with a pressure relief groove 203, and may have a second pressure relief position corresponding one-to-one to the pressure relief port 105. When the second valve core portion 200 is in the second pressure relief position, one of the multiple outlets 102 may be connected to an adjacent pressure relief port 105 through the pressure relief groove 203. Based on the above setting, after the valve body device completes the operating task of the current working position, the second valve core portion 200 may be rotated to the second pressure relief position, and the pressure inside the outlet 102 may be released through the pressure relief port 105, thereby 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 more reliable guarantee for the continuous and stable operation of the valve body device.

[0093] It can be understood that when the second valve core portion 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 outlet 102 connected to the pressure relief port 105 through the pressure relief groove 203 is an outlet 102 adjacent to the pressure relief port 105 among the multiple aforementioned outlets 102.

[0094] It is understandable that the valve body device promptly releases pressure at the discharge port 102 after completing the operating task at the current working position, which can also reduce the possibility of residual material in the valve body device leaking out in the non-working position, which is beneficial to ensure the cleanliness of the valve body device and further ensure the safe and reliable operation of the beverage machine.

[0095] like Figures 3 to 17 As shown, in a feasible embodiment, the feed port 101 is opened in the middle of the first valve core portion 100, and multiple discharge ports 102 are arranged at intervals around the feed port 101, and the pressure relief port 105 and the discharge port 102 are located on the same circumference of the first valve core portion 100; the feed groove 201 is opened along the radial direction of the second valve core portion 200, and the pressure relief groove 203 is opened along the circumferential direction of the second valve core portion 200, and the feed port 101 is connected to a partial groove of the feed groove 201 close to the middle of the second valve core portion 200.

[0096] In this technical solution, the aforementioned feed port 101 may be opened in the middle of the aforementioned first valve core part 100, and a plurality of aforementioned discharge ports 102 may be opened along the circumference of the aforementioned feed port 101, that is, the aforementioned feed port 101 and the aforementioned discharge port 102 are spaced apart along the radial direction of the aforementioned first valve core part 100, and accordingly, the aforementioned second valve core part 200 may be opened along its own radial direction with the aforementioned feed trough 201, and the aforementioned feed port 101 may be arranged to be connected to a portion of the slots of the aforementioned feed trough 201 close to the middle of the second valve core part 200, so as to facilitate the material input into the valve body device from the feed port 101 to enter the feed trough 201, and improve the first valve The concentricity between the core portion 100 and the second valve core portion 200, and then during the rotation of the second valve core portion 200 relative to the first valve core portion 100, the feed groove 201 radially opened along the second valve core portion 200 can pass through the aforementioned discharge ports 102 in sequence, and when the feed groove 201 corresponds to the aforementioned discharge port 102, the connection between the feed port 101 and the discharge port 102 is realized to distribute the material to the flow path corresponding to the discharge port 102; and, when the concentricity between the first valve core portion 100 and the second valve core portion 200 is high, it is also beneficial to further improve the structural compactness of the valve body device and enhance the miniaturization level of the valve body device.

[0097] At the same time, the pressure relief port 105 can also be arranged in the circumference of the feed port 101, and be located on the same circumference of the first valve core part 100 as the discharge port 102, that is, there is a radial interval between the pressure relief port 105 and the feed port 101, and the radial interval between the pressure relief port 105 and the feed port 101 is consistent with the radial interval between the discharge port 102 and the feed port 101, so that during the rotation of the second valve core part 200 relative to the first valve core part 100, the feed slot 201 can also pass through the pressure relief port 105, and when the feed slot 201 corresponds to the pressure relief port 105, the feed port 101 is realized. 01 is connected with the pressure relief port 105, which is convenient for the pressure relief of the feed port 101; and, when the discharge port 102 is located on the same circumference of the first valve core portion 100, the radial dimension of the first valve core portion 100 can be relatively low, which is beneficial to reducing the volume of the first valve core portion 100. At the same time, the radial dimension of the feed trough 201 is also convenient to be set according to the radial spacing between the pressure relief port 105 and the feed port 101 or the radial spacing between the discharge port 102 and the feed port 101, which is beneficial to reducing the volume of the second valve core portion 200, thereby further improving the structural compactness of the valve body device and enhancing the miniaturization level of the valve body device.

[0098] Correspondingly, the aforementioned pressure relief groove 203 can be opened along the circumference of the second valve core portion 200, so that during the rotation of the second valve core portion 200 relative to the first valve core portion 100, the pressure relief groove 203 can pass through the aforementioned discharge port 102 and the aforementioned pressure relief port 105, and when the second valve core portion 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 the pressure of the discharge port 102, reduce the internal pressure of the valve body device, and reduce the amount of residual material in the valve body device.

[0099] It can be understood that the radial spacing between the pressure relief groove 203 and the center of the second valve core portion 200 can be consistent with the radial spacing between the pressure relief port 105 or the discharge port 102 and the feed port 101, so that during the rotation of the second valve core portion 200, it is convenient for the pressure relief groove 203 to pass through the aforementioned discharge port 102 and pressure relief port 105.

[0100] For example, Figure 3 and Figure 7 As shown, the second valve core part 200 can be a disc-shaped structure. In practical applications, the second valve core part 200 can rotate around its own axis. Therefore, based on the arrangement of the disc-shaped structure, the thickness of the second valve core part 200 can be reduced while facilitating the rotation of the second valve core part 200, which is beneficial to further improve the lightweight level of the valve body device. Accordingly, the aforementioned feed groove 201 and pressure relief groove 203 can be opened on one side of the second valve core part 200 in the axial direction; Figure 3 , Figure 5 and Figure 6 As shown, the first valve core portion 100 can also be a disc-shaped structure, and the diameter of the first valve core portion 100 can be consistent with the diameter of the second valve core portion 200, so as to facilitate the centering arrangement of the first valve core portion 100 and the second valve core portion 200, thereby improving the assembly convenience of the valve body device; the aforementioned feed port 101 can be coaxial with the first valve core portion 100, and the aforementioned feed port 101 and the aforementioned discharge port 102 are both opened along the axial direction of the first valve core portion 100, thereby further facilitating the first valve core portion 100 to dock with the second valve core portion 200.

[0101] In some feasible examples, the pressure relief groove 203 may be an arc-shaped groove, the length direction of the arc-shaped groove is consistent with the circumference of the second valve core portion 200, and the two ends of the arc-shaped groove in the length direction may be arc-shaped. Accordingly, the radius of the pressure relief port 105 and the radius of the discharge port 102 may be less than or equal to the radius of the arc end of the arc-shaped groove, so that on the one hand, it is convenient for the pressure relief groove 203 to match the discharge port 102 and the pressure relief port 105, and on the other hand, it can also reduce the stress concentration of the second valve core portion 200, which is beneficial to improve the structural reliability of the second valve core portion 200 and extend the service life of the second valve core portion 200; accordingly, the two ends of the feed groove 201 along the radial direction of the second valve core portion 200 may also be arc-shaped, and the radius of the pressure relief port 105 and the radius of the discharge port 102 may be less than or equal to the radius of the arc end of the feed groove 201.

[0102] It is understandable that the aforementioned air passage groove 202 may also be an arc-shaped groove.

[0103] like Figures 4 to 17 As shown, in a feasible embodiment, the air inlet 103 and the air outlet 104 are arranged at intervals along the circumference of the feed port 101, and the air inlet 103 and the air outlet 104 are located on the same circumference of the first valve core portion 100, and the circumference of the air inlet 103 is different from the circumference of the outlet 102; the air groove 202 is opened along the circumference of the second valve core portion 200.

[0104] In this technical solution, the air inlet 103 and the air outlet 104 can also be arranged around the circumference of the feed port 101 and located on the same circumference of the first valve core portion 100. Accordingly, the air passage groove 202 can be opened along the circumference of the second valve core portion 200, so that during the rotation of the second valve core portion 200, the air passage groove 202 can pass through the air inlet 103 and the air outlet 104, and the notch of the air passage groove 202 is simultaneously connected to the air inlet 103 and the air outlet 104. When the air inlet 103 is connected to the air outlet 104 through the air passage groove 202, the gaseous material can flow to the corresponding flow path through the valve body device, thereby realizing the distribution control of the gaseous material; at the same time, on the first valve core part 100, the circumference of the air inlet 103 is different from the circumference of the outlet 102, thereby avoiding the air passage groove 202 from connecting to the outlet 102 and / or the pressure relief port 105, which is beneficial to ensuring the operating stability and reliability of the valve body device.

[0105] It can be understood that the radial spacing between the air groove 202 and the center of the second valve core part 200 can be consistent with the radial spacing between the air inlet 103 or the air outlet 104 and the feed port 101, so that during the rotation of the second valve core part 200, it is convenient for the pressure relief groove 203 to pass through the aforementioned outlet 102 and pressure relief port 105.

[0106] like Figures 3 to 17 As shown, in a feasible embodiment, the feed port 101, the discharge port 102, the air inlet 103, the air outlet 104 and the pressure relief port 105 are all opened along the axial direction of the first valve core portion 100, and the circumferential radius of the air inlet 103 is greater than the circumferential radius of the discharge port 102.

[0107] In this technical solution, the first valve core portion 100 can be provided with the feed port 101, the discharge port 102, the air inlet 103, the air outlet 104 and the pressure relief port 105 along its own axial direction, so that the aforementioned ports can be connected relatively straight, which is beneficial to improving the passability of the aforementioned ports and reducing the resistance to the passage of materials. The circumferential radius of the air inlet 103 can be set to be larger than the circumferential radius of the discharge port 102, so that during the rotation of the second valve core portion 200, the feed chute 201 is prevented from accidentally connecting to the air inlet 103 or the air outlet 104, which is beneficial to further ensure the reliability of the valve body device when performing flow control.

[0108] like Figures 3 to 17 As shown, in a feasible embodiment, the diameter of the feed port 101, the diameter of the discharge port 102 and the diameter of the pressure relief port 105 are the same; and / or the diameter of the air inlet 103 and the diameter of the air outlet 104 are the same; and / or the diameter of the feed port 101, the diameter of the discharge port 102 and the diameter of the pressure relief port 105 are all larger than the diameter of the air inlet 103, and the diameter of the feed port 101, the diameter of the discharge port 102 and the diameter of the pressure relief port 105 are all larger than the diameter of the air outlet 104.

[0109] In this technical solution, the diameter of the feed port 101, the diameter of the discharge port 102 and the diameter of the pressure relief port 105 can be set to be the same, so that on the one hand, by keeping the diameters of the feed port 101 and the discharge port 102 consistent, the consistency of the flow rate at the feed port 101 and the discharge port 102 can be improved, and a large change in the flow rate of the material in the process of flowing through the valve body device can be avoided. When the valve body device performs an operating task at any working position, it is helpful to maintain the internal pressure of the valve body device stable, thereby improving the operating stability and reliability of the valve body device; on the other hand, On the one hand, by further setting the diameters of the feed port 101, the discharge port 102 and the pressure relief port 105 to be the same, it is possible to facilitate the matching of the feed chute 201 and the pressure relief port 105 with the feed port 101, the discharge port 102 and the pressure relief port 105, which is beneficial to simplify the structure of the feed chute 201 and the pressure relief port 103. At the same time, in the process of machining the first valve core portion 100, it is convenient to open the feed port 101, the discharge port 102 and the pressure relief port 105 based on machining tools of the same specification, which is beneficial to further reduce the machining cost of the valve body device.

[0110] In this technical solution, the diameter of the air inlet 103 and the diameter of the air outlet 104 can be set to be the same, so that on the one hand, the consistency of the flow rate at the air inlet 103 and the air outlet 104 can be improved, and a large change in the flow rate of the gaseous material in the process of flowing through the valve body device can be avoided, which is beneficial to maintaining the internal pressure of the valve body device stable and improving the operating stability and reliability of the valve body device; on the other hand, in the process of processing the first valve core portion 100, it is convenient to open the air inlet 103 and the air outlet 104 based on the same specification of processing tools, which is beneficial to further reduce the processing cost of the valve body device.

[0111] In this technical solution, the diameter of the feed port 101, the diameter of the discharge port 102 and the diameter of the pressure relief port 105 can be set to be larger than the diameter of the air inlet 103, and the diameter of the feed port 101, the diameter of the discharge port 102 and the diameter of the pressure relief port 105 can be set to be larger than the diameter of the air outlet 104, so that the diameters of the air inlet 103 and the air outlet 104 can be made relatively small, which is beneficial to ensure that the gaseous material has a higher flow rate and pressure during the air supply process, thereby improving the distribution efficiency of the gaseous material.

[0112] like Figure 5 As shown, in a feasible embodiment, around the circumference of the feed port 101, a plurality of discharge ports 102 are arranged at a preset interval angle θ, and the pressure relief port 105 is arranged at an interval of 0.5 times the preset interval angle θ with the adjacent discharge ports 102, and the preset interval angle satisfies:

[0113] θ≤360° / a

[0114] Wherein, θ is a preset interval angle, and a is the number of the discharge ports 102 .

[0115] In this technical solution, when a plurality of the aforementioned discharge ports 102 are opened at intervals along the circumference of the feed port 101, a preset interval angle θ can be maintained between adjacent discharge ports 102, so that when the second valve core portion 200 switches between working positions, an integer multiple of the aforementioned preset interval angle θ can be used as a rotation angle, which is beneficial to improving the convenience and accuracy of the rotation control of the second valve core portion 200, reducing the error of the second valve core portion 200 when switching between working positions, and providing further guarantee for the valve body device to stably and reliably perform pressure relief and flow on-off control.

[0116] At the same time, when a pressure relief port 105 needs to be opened between two adjacent outlets 102, the pressure relief port 105 and the adjacent outlets 102 can be arranged at a spacing angle θ of 0.5 times the preset spacing angle, so that when switching between the first pressure relief position and the working position, the second valve core portion 200 can also rotate at a relatively fixed rotation angle, further ensuring the stable and reliable execution of the pressure relief process.

[0117] It is understandable that if Figure 5 As shown, the preset interval angle θ may be the angle of a central angle with the axis position of the first valve core portion 100 as the center, and two sides of the central angle pass through the axes of two adjacent discharge ports 102 respectively.

[0118] For example, Figure 5 As shown, the valve body device can have four outlets 102, and the preset interval angle θ between two adjacent outlets 102 can be less than or equal to 90°. Considering the uniform distribution of the outlets 102 along the circumference of the first valve core portion 100, the preset interval angle θ can be set equal to 90°.

[0119] In some feasible examples, the valve body device may further include a driving part, which may be a driving device such as a motor that can output rotation, and the driving part is connected to the second valve core part 200, and is used to drive the second valve core part 200 to rotate relative to the first valve core part 100, thereby improving the convenience of use of the valve body device. By way of example, the aforementioned driving part may be a stepper motor, which can output small-angle rotation and has high parking flexibility, which is beneficial to improving the rotation stability of the second valve core part 200 and improving the movement accuracy of the second valve core part 200 during the position switching process; at the same time, based on the setting of the aforementioned preset interval angle θ, it is also beneficial to improve the convenience of output control of the driving part in actual applications.

[0120] It can be understood that, when the driving unit is the aforementioned stepping motor, the aforementioned preset interval angle can be an even multiple of the step angle of the stepping motor, and accordingly, 0.5 times the preset interval angle θ can be an integer multiple of the aforementioned step angle.

[0121] like Figure 7 As shown, in a feasible implementation, along the circumference of the second valve core portion 200, the feed groove 201 and the pressure relief groove 203 are arranged at an interval 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.

[0122] In this technical solution, along the circumference of the second valve core portion 200, the feed groove 201 and the pressure relief groove 203 are arranged at an interval 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 portion 200. Based on the above arrangement, after the valve body device completes the operating task of the current working position, the second valve core portion 200 can be rotated along the rotation direction by 0.5 times the above 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 feed groove 201, that is, the second valve core portion 200 enters the first pressure relief position to achieve pressure relief on the feed port 101.

[0123] When the second valve core portion 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, thereby setting the opening length of the pressure relief groove 203 along the circumference of the second valve core portion 200. For example, when the pressure relief groove 203 is an arc-shaped groove, the central angle corresponding to the 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 the pressure relief port 105 also exists 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, part of the second pressure relief position can be overlapped with the first pressure relief position, so as to facilitate the synchronous pressure relief of the feed port 101 and the discharge port 102 after the valve body device completes the operating task of the current working position, which is beneficial to improve the timeliness of the pressure relief of the discharge port 102 and provide further guarantee for the stable and reliable operation of the valve body device.

[0124] In a feasible embodiment, the first valve core portion 100 is also formed with a first connecting groove 106, multiple second connecting grooves 107 and a pressure relief channel 108, wherein the first connecting grooves 106 are arranged around the feed port 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 multiple pressure relief ports 105.

[0125] In this technical solution, the first valve core portion 100 may also include a first connecting groove 106, a second connecting groove 107 and a pressure relief channel 108, wherein the first connecting groove 106 is arranged around the feed port 101, the number of the second connecting grooves 107 is multiple, and each of the pressure relief ports 105 is connected to the first connecting groove 106 through a second connecting groove 107, so that when the number of the pressure relief ports 105 is more than one, the multiple pressure relief ports 105 can be connected to each other through the first connecting groove 106 and the second connecting groove 107, and the pressure relief channel 108 One end is connected to one of the multiple pressure relief ports 105, and the other end is used to connect to the atmosphere. Based on the above-mentioned arrangement, when the second valve core portion 200 is in various pressure relief positions, pressure relief can be performed through the above-mentioned pressure relief channel 108, thereby further improving the integration of the pressure relief path of the valve body device, improving the structural compactness of the valve body device, and while facilitating the release of the internal pressure of the valve body device, it is beneficial to reduce the number of through holes in the first valve core portion 100, which is beneficial to further ensure the structural strength of the first valve core portion 100 and extend the service life of the first valve core portion 100.

[0126] It can be understood that one of the multiple aforementioned pressure relief ports 105 is directly connected to the aforementioned pressure relief channel 108, and 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 portion 100, the aforementioned pressure relief channel 108 and the aforementioned pressure relief ports 105 directly connected to the aforementioned pressure relief channel 108 can be formed by opening a through hole on the first valve core portion 100, and the remaining pressure relief ports 105 can be blind holes opening toward the second valve core portion 200, thereby reducing the number of through holes opened on the first valve core portion 100.

[0127] like Figures 1 to 4 As shown, in a feasible embodiment, it also includes: a base portion 300; a bearing portion 400, which is arranged on the base portion 300, and the second valve core portion 200 is connected to the bearing portion 400; a joint portion 500, which is arranged on the first valve core portion 100, and the joint portion 500 is formed with a feed flow path 501, an inlet gas flow path, an outlet gas flow path, a pressure relief flow path 505 and a plurality of outlet flow paths 502, the feed flow path 501 is connected to the feed port 101, each outlet flow path 502 is connected to a outlet port 102, each pressure relief port 105 is connected to the pressure relief flow path 505, the inlet gas flow path is connected to the inlet port 103, and the outlet gas flow path is connected to the outlet port 104.

[0129] It is understandable that, when the first valve core portion 100 is formed with the pressure relief channel 108 , one end of the pressure relief channel 108 away from the pressure relief port 105 is connected to the pressure relief flow path 505 .

[0133] It is understandable 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 to further ensure the overall operational reliability of the valve body device.

[0136] It is understandable that the sealing portion 600 may also be formed with a fourth through hole connected to the air inlet 103 and a fifth through hole connected to the air outlet 104 .

[0137] In a feasible embodiment, a first limiting structure is formed on the side of the joint part 500 facing the sealing part 600, and a second limiting structure 610 is formed on the sealing part 600, and the first limiting structure is adapted to the second limiting structure 610; and / or a third limiting structure is formed on the side of the first valve core part 100 facing the sealing part 600, and a fourth limiting structure is formed on the sealing part 600, and the third limiting structure is adapted to the fourth limiting structure.

When the sealing part 600 is connected to the aforementioned joint part 500, the aforementioned first limiting structure and the aforementioned second limiting structure 610 can be connected to each other to fix the position of the sealing part 600 relative to the joint part 500, thereby ensuring the sealing effect between the sealing part 600 and the joint part 500.

[0139] In this technical solution, the aforementioned first valve core portion 100 and the aforementioned sealing portion 600 can be respectively formed with a third limiting structure and a fourth limiting structure, and the shape of the aforementioned third limiting structure is adapted to the shape of the aforementioned fourth limiting structure.

[0140] It is understandable that the specific forms of the aforementioned limiting structures can be various, such as Figure 3 As shown, the first limiting structure can be one of a protrusion structure and a groove structure, and correspondingly, the second limiting structure 610 can be the other of a protrusion structure and a groove structure, and the protrusion structure and the groove structure have mutually adaptive shapes, and the third limiting structure and the fourth limiting structure are the same.

[0141] like Figure 4 As shown, in a possible implementation, the gas outlet 104 is communicated with one of the plurality of material outlets 102 .

[0142] In this technical solution, the gas outlet 104 can be connected to one of the multiple material outlets 102, so that in actual applications, the material outlet 102 can be set as a through hole that passes through the first valve core portion 100, and the gas outlet 104 is set as a blind hole that is open toward the second valve core portion 200 and connected to one of the multiple aforementioned material outlets 102, that is, the gaseous material can be output through the material outlet 102 that is connected to the aforementioned gas outlet 104, which is beneficial to reduce the number of through holes on the first valve core portion 100, improve the structural reliability of the first valve core portion 100, and reduce the processing cost of the first valve core portion 100.

[0143] It can be understood that, in combination with the foregoing, in actual applications, the air inlet 103 and the air outlet 104 can be arranged on the same circumference of the first valve core portion 100, and the discharge port 102 and the pressure relief port 105 can be arranged on the same circumference of the valve core portion, and the circumference of the air inlet 103 is different from the circumference of the pressure relief port 105, so as to avoid the air passage groove 202 connecting the discharge port 102 and the pressure relief port 105.

[0144] like Fig.13 and Fig.14 As shown, in a feasible embodiment, at least one of the multiple discharge ports 102 is an arc-shaped port 102a opened along the circumference of the first valve core portion 100, and the working position corresponding to the arc-shaped port 102a includes a first workstation and a second workstation; wherein, when the second valve core portion 200 is in the first workstation, the second valve core portion 200 covers the air inlet 103 and / or the air outlet 104; when the second valve core portion 200 is in the second workstation, the air inlet 103 is connected to the air outlet 104 through the air groove 202.

[0145] In this technical solution, one of the multiple discharge ports 102 can be set as an arc-shaped port 102a, and the arc direction of the aforementioned arc-shaped port 102a is consistent with the circumferential direction of the first valve core part 100. Accordingly, the working position corresponding to the aforementioned arc-shaped port 102a may include two workstations. When the second valve core part 200 is in the aforementioned first workstation or the second workstation, the feed port 101 can be connected to the arc-shaped port 102a through the material passage groove 201. When the second valve core part 200 is in the first workstation, the second valve core part 200 covers the air inlet 103 and / or the air outlet 104, so that the valve body device can output a single type of material. When the second valve core part 200 is in the second workstation, the air inlet 103 is connected to the air outlet 104 through the air passage groove 202, so that the valve body device can output different types of materials through one discharge port 102 and the air outlet 104 at the same time, thereby improving the flexibility of the valve body device in the material dispensing process, which is conducive to further simplifying the flow path system of the beverage machine.

[0146] Exemplarily, in combination with the example of the aforementioned valve body device being applied to a coffee machine, the discharge port 102 corresponding to the working position M3 can be set as an arc-shaped port 102a. Accordingly, the arc-shaped port 102a is used to connect to the foaming device of the coffee machine. When the second valve core portion 200 is in the aforementioned first position, the valve body device can only distribute the steam output by the liquid heating device to the foaming device, thereby heating the dairy product in the foaming device; when the second valve core portion 200 is in the aforementioned second position, the valve body device can supply steam and air to the foaming device at the same time, thereby facilitating the foaming device to make foam.

[0147] like Fig.13 and Fig.14 As shown, in a feasible embodiment, when the second valve core part 200 is in the second position, the feed port 101 is used to connect to the steam generating device, the air inlet 103 is used to connect to the air supply device, and the discharge port 102 and the air outlet 104 are used to connect to the foaming device.

[0148] In this technical solution, when the second valve core portion 200 is in the second working position, the aforementioned feed port 101 can be used to connect to the steam generating device to receive the steam output by the steam generating device, and the aforementioned air inlet 103 can be connected to the air supply device to receive the air output by the air supply device, and accordingly, the aforementioned arc-shaped port 102a and the aforementioned air outlet 104 can both be connected to the foaming device. It can be understood that the foaming device can be used to make milk foam for coffee, so based on the aforementioned setting, the valve body device can be applied to the coffee machine or the coffee making process to control the flow path between the foaming device, the steam generating device and the air supply device.

[0149] It can be understood that the liquid heating device of the aforementioned coffee machine may include the aforementioned steam generating device, and the air supply device of the aforementioned coffee machine may include the aforementioned air supply device.

[0150] According to a second aspect of an embodiment of the present application, a beverage machine is proposed, comprising: a valve body device as proposed in any one of the first aspects above, a plurality of outlets 102 including a first liquid outlet, a second liquid outlet, a steam outlet and a cleaning outlet; a brewing device, the first liquid outlet is connected to the brewing device; a liquid outlet device, formed with a first liquid inlet end and a second liquid inlet end, the output end of the brewing device is connected to the first liquid inlet end, and the second liquid outlet is connected to the second liquid inlet end; a foaming device, the air outlet 104, the steam outlet and the cleaning outlet are all connected to the foaming device.

[0151] The beverage machine provided in the embodiment of the present application includes a brewing device, a liquid outlet device, a foaming device and a valve body device as proposed in any one of the first aspects above, wherein the brewing device can be connected to the first liquid outlet of the valve body device, the first liquid inlet end of the liquid outlet device can be connected to the output end of the brewing device, the second liquid inlet end of the liquid outlet device can be connected to the second liquid outlet of the valve body device, and the foaming device can be connected to the gas outlet 104, the steam port and the cleaning port of the valve body device, so that during use, by switching the working position of the aforementioned second valve core part 200, the material in the valve body device can be distributed to the brewing device or the liquid outlet device or the foaming device, thereby ensuring that the brewing device, the liquid outlet device and the foaming device can receive the material during the beverage making process, while reducing the number of valve components used in the beverage machine, which is conducive to improving the miniaturization and lightweight level of the beverage machine, simplifying the flow 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.

[0152] It can be understood that the valve body device provided in the embodiment of the present application includes a first valve core portion 100 and a second valve core portion 200, wherein the first valve core portion 100 is formed with a feed port 101 and a discharge port 102 to facilitate the flow of materials into or out of the valve body device, the second valve core portion 200 is arranged on the first valve core portion 100, and is formed with a feed trough 201 connected to the feed port 101, the second valve core portion 200 can rotate relative to the first valve core portion 100, the number of the discharge ports 102 is multiple, and the multiple discharge ports 102 are arranged at intervals on the first valve core portion 100 along the rotation direction of the second valve core portion 200 Part 100, so that during the rotation of the second valve core part 200, the aforementioned material passage trough 201 is connected with different discharge ports 102 in sequence. Accordingly, the second valve core part 200 has a plurality of working positions, and each of the aforementioned working positions corresponds to one of the aforementioned discharge ports 102. When the second valve core part 200 is rotated to the aforementioned working position, the discharge port 102 corresponding to the current working position of the second valve core part 200 can be connected to the feed port 101 through the material passage trough 201, so that the material flowing into the valve body device through the feed port 101 can further flow to the discharge port 102 and be discharged from the valve body device.

[0153] At the same time, the first valve core portion 100 is also formed with an air inlet 103 and an air outlet 104, and the second valve core portion 200 is also formed with an air passage groove 202. One of the multiple aforementioned working positions is a gas injection station. Accordingly, when the second valve core portion 200 is in the aforementioned gas injection station, the aforementioned air inlet 103 and the aforementioned air inlet 103 can be connected through the aforementioned air passage groove 202.

[0154] It is understandable that if Fig. 9 , Fig.11 , Fig.13 , Fig.14 and Fig.16 As shown, 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 slot 201, and other discharge ports 102 that do not have a corresponding relationship with the aforementioned working position are terminated at the aforementioned feed port 101; Fig.10 , Fig.12 , Fig.15 and Fig.17 As shown, when the second valve core portion 200 is not in the working position, the feed port 101 and any of the discharge ports 102 are in a cut-off state.

[0155] It can be understood that the beverage machine can be used as a coffee machine in actual application, the liquid outlet device can be used to output liquid, the brewing device can be used to brew coffee powder, and the frothing device can be used to make milk froth.

[0156] In some feasible examples, the beverage machine may also include a feeding device and an air supply device. The aforementioned feeding device may be a liquid heating device, which can be used to heat water and can be used to output steam or heated water. The feed port 101 of the valve body device can be connected to the aforementioned liquid heating device, so that the beverage machine can distribute hot water or steam to the aforementioned brewing device, liquid outlet device or foaming device through the valve body device; the aforementioned air supply device can be used to output air, and the air inlet 103 of the valve body device can be connected to the aforementioned air supply device, and the air output by the air supply device can be distributed to the aforementioned foaming device.

[0157] For example, Figures 9 to 17 As shown, the first valve core part 100 can be provided with four outlets 102 and one feed port 101, and the second valve core part 200 can be provided with a feed trough 201 connected to the aforementioned feed port 101, and the aforementioned four outlets 102 can be respectively a first liquid outlet, a second liquid outlet, a steam port and a cleaning port, wherein 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 second liquid outlet corresponding to the working position M1 of the second valve core part 200 can be used to connect to the second liquid inlet end of the aforementioned liquid outlet device; the first liquid outlet corresponding to the working position M2 of the second valve core part 200 can be connected to the aforementioned brewing device; the steam port corresponding to the working position M3 of the second valve core part 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; the air inlet 103 can be connected to the aforementioned air supply device, the air outlet 104 can be connected to the aforementioned foaming device, and the working position M3 can be a gas injection station.

[0158] Based on the above settings, Fig. 9 As shown, when the beverage machine needs to output hot water, the second valve core part 200 can be controlled to rotate to the working position M1 to directly output the hot water output by the liquid heating device through the liquid outlet device; Fig.11 As shown, when it is necessary to brew coffee powder, the second valve core portion 200 can be controlled to rotate to the working position M2 to distribute the hot water output by the liquid heating device to the brewing device; Fig.13As shown, when it is necessary to make milk froth, the second valve core part 200 can be controlled to rotate to the working position M3 to distribute the steam output by the liquid heating device to the frothing device. At the same time, since the working position M3 is the aforementioned gas injection station, the gas outlet 104 can be connected to the gas inlet 103 through the gas groove 202 at the same time to distribute the air output by the gas supply device to the frothing device. Then, in the process of making coffee containing milk froth, the distribution control of steam and air can be synchronously realized through the valve body device, which is conducive to further simplifying the flow path between the gas supply device, the liquid heating device and the milk frothing device, reducing the use of valve components of the coffee machine, improving the miniaturization and lightweight level of the coffee machine, and reducing the production cost of the coffee machine; Fig.16 As shown, when the frothing device needs to be cleaned, the second valve core portion 200 can be controlled to rotate to the working position M4 to distribute the hot water output by the liquid heating device to the frothing device to clean the milk frothing device.

[0159] It is easy to understand that, based on the above-mentioned arrangement of the valve body device, it is possible to improve the integration of the flow system of the beverage machine while ensuring the convenience of pressure relief of the valve body device.
