[0074] As Figures 1 to 17As shown, according to the first aspect of the embodiments of the present application, a valve body device is provided, which comprises: a first valve core part 100, the first valve core part 100 being formed with an air inlet 103, an air outlet 104, a material inlet 101 and a plurality of material outlets 102; and a second valve core part 200, which is rotatably arranged on the first valve core part 100, the second valve core part 200 being formed with a material passage 201 and an air passage 202, the material passage 201 being communicated with the material inlet 101, the plurality of material outlets 102 being arranged at intervals along the rotation direction of the second valve core part 200, the second valve core part 200 having a plurality of working positions, each working position corresponding to one material outlet 102, and in the case that the second valve core part 200 is at a working position, the corresponding material outlet 102 is communicated with the material inlet 101 through the material passage 201; wherein one of the plurality of working positions is a gas injection position, and in the case that the second valve core part 200 is at the gas injection position, the air inlet 103 is communicated with the air outlet 104 through the air passage 202.

[0075] The valve body device provided by the embodiments of the present application comprises a first valve core part 100 and a second valve core part 200, wherein the first valve core part 100 is formed with a material inlet 101 and a material outlet 102 to facilitate the flow of material 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 material passage 201 communicated with the material inlet 101, the second valve core part 200 can rotate relative to the first valve core part 100, the number of the material outlets 102 is plural, and the plurality of material outlets 102 are arranged at intervals on the first valve core part 100 along the rotation direction of the second valve core part 200, so as to facilitate the material passage 201 to be communicated with different material outlets 102 in turn during the rotation of the second valve core part 200, accordingly, the second valve core part 200 has a plurality of working positions, each working position corresponds to one material outlet 102, and in the case that the second valve core part 200 rotates to a working position, the material outlet 102 corresponding to the current working position of the second valve core part 200 can be communicated with the material inlet 101 through the material passage 201, so as to enable the material flowing into the valve body device through the material inlet 101 to further flow to the material outlet 102 and be discharged from the valve body device.

[0076] Meanwhile, the first valve core part 100 is further formed with an air inlet 103 and an air outlet 104, and the second valve core part 200 is further formed with an air passage 202, one of the plurality of working positions is a gas injection position, accordingly, in the case that the second valve core part 200 is at the gas injection position, the air inlet 103 and the air outlet 104 can be communicated through the air passage 202.

[0077] It should be noted that, Figure 8 the dashed line with an arrow in FIG. 1 is used to schematically represent 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 in the formula are used to represent the working positions schematically.

[0078] It can be understood that, as Figure 9 , Figure 11 , Figure 13 , Figure 14 and Figure 16 illustrated, in the case that the second valve core part 200 is in any working position, the outlet port 102 corresponding to the working position can be communicated with the inlet port 101 through the material passage 201, and other outlet ports 102 not having a corresponding relationship with the working position are blocked from the inlet port 101; as Figure 10 , Figure 12 , Figure 15 and Figure 17 illustrated, in the case that the second valve core part 200 is not in a working position, the inlet port 101 and any outlet port 102 are in a blocked state.

[0079] Therefore, based on the above arrangement, in actual application, the valve body device can be applied as a component of a beverage machine. It can be understood that the beverage machine can be, but is 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 path system, and the material for making beverages can flow in the flow path system, and by controlling the on-off of different flow paths in the flow path system, the beverage machine can supply the material to different process components participating in beverage making, so as to perform corresponding beverage making processes; taking the beverage machine as a coffee machine as an example, the process components participating in beverage making can include, but are not limited to, brewing devices, foaming devices, liquid outlet devices, material supply devices, air supply devices, etc., and the material can be, but is not limited to, water, steam, air, etc.

[0080] Taking the case that the valve body device is applied to the beverage machine as an example, the inlet port 101 of the valve body device can be used to communicate with the material supply device of the beverage machine, and the plurality of outlet ports 102 can be used to communicate with different flow paths respectively, and the driving part can drive the second valve core part 200 to rotate to different working positions to communicate the corresponding flow paths, so as to distribute the material to the corresponding flow paths, thereby avoiding configuring 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, being conducive to simplifying the flow path system, reducing the volume and mass of the flow path system, being conducive to improving the miniaturization and lightness level of the beverage machine, improving the installation convenience of the beverage machine, and saving the production cost of the beverage machine.

[0081] Meanwhile, the air inlet 103 of the valve body device can also be used to communicate with 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 dispensing of the beverage machine, and when the second valve core part 200 is in the aforementioned air injection working position, the aforementioned feed inlet 101 can also communicate with one of the plurality of discharge outlets 102 through the material passage 201, so that the valve body device can realize synchronous control of different types of material dispensing, on the one hand, which is conducive to improving the material dispensing efficiency of the beverage machine and improving the beverage making efficiency of the beverage machine; on the other hand, it can also enhance the adaptability of the valve body device to the beverage machine that needs to synchronously supply different materials, further expanding the application range of the valve body device.

[0082] For example, when the valve body device is further applied to a coffee machine, the aforementioned coffee machine can include a feed device, an air supply device, a brewing device, a liquid outlet device, and a foaming device, as shown in Figures 5 to 17 The valve body device can have one aforementioned feed inlet 101, four aforementioned discharge outlets 102, one aforementioned air inlet 103, and one aforementioned air outlet 104, as shown in Figures 9 to 17 The four aforementioned discharge outlets 102 correspond to working positions M1, M2, M3, and M4, respectively, wherein, as shown in Figure 13 The working position M3 can be the aforementioned air injection working position. Correspondingly, the aforementioned feed device can be a liquid heating device for heating water and can be used to output steam or heated water, the feed inlet 101 of the valve body device can be communicated with 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 communicated with the aforementioned brewing device and a second liquid inlet end communicated with one discharge outlet 102 of the aforementioned valve body device, so that the liquid outlet device can receive the liquid output by the brewing device or the liquid output by the valve body device, the discharge outlet 102 corresponding to the working position M1 can be used to communicate with the second liquid inlet end of the aforementioned liquid outlet device; the aforementioned brewing device can be used to brew coffee powder, one discharge outlet 102 of the aforementioned valve body device can be communicated with the brewing device, and the working position M2 of the second valve core part 200 can be communicated with the aforementioned brewing device; the aforementioned foaming device is used to make milk foam, it can be understood that some coffee drinks contain milk foam, and air and steam are often needed when foaming, and the foaming device often needs to be cleaned in time after the milk foam is made, so that the air outlet 104 and two discharge outlets 102 of the valve body device can be communicated with the aforementioned foaming device, as shown in Figures 9 to 17As shown, the outlet 102 corresponding to the working position M3 of the second valve core part 200 and the outlet 102 corresponding to the working position M4 of the second valve core part 200 can be connected to the aforementioned frothing device, wherein the outlet 102 corresponding to the working position M3 can be used to output steam required for frothing to the frothing device, the outlet 102 corresponding to the working position M4 can be used to output hot water for cleaning to the frothing device, and the outlet 104 can be used to output air required for frothing to the frothing device; the aforementioned air supply device can be used to supply air required for frothing to the frothing 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 aforementioned arrangement, as shown, Figure 9 when hot water needs to be output by the beverage machine, the second valve core part 200 can be controlled to rotate to the working position M1, so that the hot water output by the liquid heating device is directly output through the liquid outlet device; as shown, Figure 11 when coffee powder needs to be brewed, the second valve core part 200 can be controlled to rotate to the working position M2, so that the hot water output by the liquid heating device is supplied to the brewing device; as shown, Figure 13 when milk froth needs to be made, the second valve core part 200 can be controlled to rotate to the working position M3, so that the steam output by the liquid heating device is supplied to the frothing device, and since the working position M3 is the aforementioned air injection position, the outlet 104 can be connected to the air inlet 103 through the air passage 202 at the same time, so that the air output by the air supply device is supplied to the frothing device, and then during the process of making coffee containing milk froth, the supply of steam and air can be controlled synchronously through the valve body device, which is beneficial to further simplify the flow path among the air supply device, the liquid heating device and the milk froth device, reduce the use amount of valve components of the coffee machine, improve the miniaturization and light weight level of the coffee machine, and reduce the production cost of the coffee machine; as shown, Figure 16 when the frothing device needs to be cleaned, the second valve core part 200 can be controlled to rotate to the working position M4, so that the hot water output by the liquid heating device is supplied to the frothing device to perform cleaning operation of the milk froth device.

[0084] It can be understood that the above description is only an exemplary description taking the valve body device applied to the beverage machine or the coffee machine as an example, and is not used to limit the present application. For other devices with flow path systems, such as fluid machines, hydraulic machines, etc., the valve body device provided by the embodiments of the present application also has good applicability, and when applied to other devices with flow path systems, it is also beneficial to reduce the use amount of valve components of the corresponding device, simplify the flow path system of the corresponding device, improve the integration of the flow path system, and facilitate the further reduction of the volume, weight and production cost of the corresponding device, which will not be illustrated one by one in combination with actual application scenarios.

[0085] As shown, Figures 3 to 6 , Figures 8 to 17As shown, in one possible implementation, the first valve core part 100 is further formed with at least one pressure relief port 105, and at least one pressure relief port 105 is arranged between each group of two adjacent discharge ports 102; the second valve core part 200 is further provided with at least one first pressure relief position, each first pressure relief position corresponds to one pressure relief port 105, and the corresponding pressure relief port 105 is communicated with the feed port 101 through the feed slot 201 when the second valve core part 200 is in the first pressure relief position.

[0086] In this technical solution, the first valve core part 100 can be further formed with a pressure relief port 105, which is used to communicate with the atmosphere. Correspondingly, the second valve core part 200 is further provided with a first pressure relief position corresponding to the pressure relief port 105. When the second valve core part 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 part 200 can be communicated with the feed port 101 through the feed slot 201. Therefore, during use, after the valve body device completes the task of the current working position, the second valve core part 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 prolong the service life of the valve body device, reduce the internal pressure of the valve body device, and provide protection for the continuous and stable operation of the valve body device.

[0087] Meanwhile, the number of pressure relief ports 105 is at least one, and at least one pressure relief port 105 is arranged between each group of two adjacent discharge ports 102. Therefore, in the rotation direction of the second valve core part 200, the pressure relief port 105 can be adjacent to the discharge port 102, which facilitates the switching between the working position and the first pressure relief position of the second valve core part 200, and is beneficial to the valve body device to more quickly switch to the adjacent first pressure relief position after completing the task of the current working position, so that the feed port 101 is communicated with the pressure relief port 105 through the feed slot 201 to release the pressure of the feed port 101, avoid the valve body device to maintain a high internal pressure after working, and improve the pressure release execution efficiency of the valve body device.

[0088] It can be understood that timely releasing the pressure of the feed port 101 after the valve body device completes the task of the current working position can also reduce the possibility of the remaining material in the valve body device to seep 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] As shown in Figure 5 , Figure 6 and Figure 8 , the specific number and position of the pressure relief port 105 can be set according to the actual needs of the valve body device; as shown in Figure 5 and Figure 8As shown, in the example of the valve body device applied to the coffee machine as previously described, the first valve core 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 200, i.e. Figures 9 to 17 the first pressure relief position N1 corresponding to the pressure relief port 105, and a pressure relief port 105 between the discharge port 102 corresponding to the working position M4 and the discharge port 102 corresponding to the working position M1, i.e. Figures 9 to 17 the first pressure relief position N2 corresponding to the pressure relief port 105. It can be understood that, after the coffee machine directly outputs hot water through the liquid output device or supplies hot water required for cleaning to the frothing device, there is a relatively high pressure in the inlet port 101, so that based on the foregoing arrangement, the second valve core 200 can be switched to the adjacent first pressure relief position along the rotation direction to release the pressure inside the valve body device. When the valve body device completes the task of the working position M2 or the working position M3, the pressure in the inlet port 101 is relatively small, so that the pressure relief port 105 can not be provided between the working position M2 and the working position M3, and the pressure relief port 105 can not be provided between the working position M3 and the working position M4, thereby reducing the number of openings of the first valve core 100 and ensuring the sealing performance and structural reliability of the first valve core 100. Correspondingly, as shown in Figure 6 , when the valve body device completes the task of each working position, the inlet port 101 will have a relatively high pressure, the first valve core 100 can be provided with a pressure relief port 105 between any two adjacent discharge ports 102 along the rotation direction of the second valve core 200, so as to facilitate the second valve core 200 to rotate to the adjacent first pressure relief position more quickly after completing the task of any working position to release the pressure of the inlet port 101.

[0090] It can be understood that, when the valve body device completes the task of the current working position, timely releasing the pressure of the inlet port 101 can also reduce the possibility of the remaining material in the valve body device leaking 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] As shown in Figure 3 , Figures 7 to 17 , in a possible implementation, the second valve core 200 is further provided with a pressure relief groove 203, and the second valve core 200 has at least one second pressure relief position, each second pressure relief position corresponds to a pressure relief port 105, and one of the plurality of discharge ports 102 and the adjacent pressure relief port 105 are communicated through the pressure relief groove 203 when the second valve core 200 is in the second pressure relief position.

[0092] 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 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.

[0093] 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.

[0094] 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.

[0095] like Figures 3 to 17 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.

[0096] In the technical scheme, the middle part of the first valve core part 100 can be provided with the feed port 101, and a plurality of discharge ports 102 can be arranged along the circumference of the feed port 101, that is, the feed port 101 and the discharge port 102 are spaced apart along the radial direction of the first valve core part 100. Correspondingly, the second valve core part 200 can be provided with the material passing groove 201 along the radial direction of the second valve core part 200, and the part of the material passing groove 201 close to the middle part of the second valve core part 200 can be communicated with the feed port 101, so that the material input into the valve body device through the feed port 101 can enter the material passing groove 201, and the centering between the first valve core part 100 and the second valve core part 200 is improved, and then in the process of rotating the second valve core part 200 relative to the first valve core part 100, the material passing groove 201 arranged along the radial direction of the second valve core part 200 can pass through each discharge port 102 in sequence, and when the material passing groove 201 corresponds to the discharge port 102, the communication between the feed port 101 and the discharge port 102 is realized, so that the material can be distributed to the flow path corresponding to the discharge port 102; and when the centering between the first valve core part 100 and the second valve core part 200 is high, the compactness of the valve body device is further improved, and the miniaturization level of the valve body device is improved.

[0097] Meanwhile, the pressure relief port 105 can also be arranged along the circumference of the feed port 101 and located on the same circumference of the first valve core part 100 as the discharge port 102, that is, the pressure relief port 105 and the feed port 101 are spaced apart along the radial direction, and the radial spacing between the pressure relief port 105 and the feed port 101 is consistent with the radial spacing between the discharge port 102 and the feed port 101, so that in the process of rotating the second valve core part 200 relative to the first valve core part 100, the material passing groove 201 can also pass through the pressure relief port 105, and when the material passing groove 201 corresponds to the pressure relief port 105, the communication between the feed port 101 and the pressure relief port 105 is realized, so that the feed port 101 can be relieved; and when the discharge port 102 is located on the same circumference of the first valve core part 100, the radial dimension of the first valve core part 100 can be relatively low, which is beneficial to reducing the volume of the first valve core part 100, and the radial dimension of the material passing groove 201 can also 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 part 200, and further improving the compactness of the valve body device and the miniaturization level of the valve body device.

[0098] Correspondingly, the aforementioned pressure relief groove 203 can be formed along the circumference of the second valve core part 200, so that during the rotation of the second valve core part 200 relative to the first valve core part 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 part 200 is in the aforementioned second pressure relief position, the aforementioned discharge port 102 can be communicated with the aforementioned pressure relief port 105 through the aforementioned pressure relief port 105, so as to relieve the pressure of the discharge port 102, reduce the internal pressure of the valve body device, and reduce the residual amount of 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 part 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 as to facilitate the passage of the pressure relief groove 203 through the aforementioned discharge port 102 and the pressure relief port 105 during the rotation of the second valve core part 200.

[0100] Exemplarily, as shown in Figure 3 and Figure 7 , the second valve core part 200 can be a disc-shaped structure, and in actual application, the second valve core part 200 can rotate around its own axis, so that 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 conducive to further improving the lightweight level of the valve body device. Correspondingly, the aforementioned material passing groove 201 and the pressure relief groove 203 can be formed on one side of the second valve core part 200 in the axial direction; as shown in Figure 3 , Figure 5 and Figure 6 , the first valve core part 100 can also be a disc-shaped structure, and the diameter of the first valve core part 100 can be consistent with the diameter of the second valve core part 200, so as to facilitate the centering arrangement of the first valve core part 100 and the second valve core part 200, and improve the assembly convenience of the valve body device; the aforementioned feed port 101 can be coaxial with the first valve core part 100, and the aforementioned feed port 101 and the aforementioned discharge port 102 are formed along the axial direction of the first valve core part 100, so as to further facilitate the butt joint of the first valve core part 100 and the second valve core part 200.

[0101] In some possible examples, the foregoing pressure relief groove 203 can be an arc-shaped groove, the length direction of the arc-shaped groove is consistent with the circumferential direction of the second valve core part 200, and the two ends in the length direction of the arc-shaped groove can be in the form of a circular arc. Correspondingly, the radius of the foregoing pressure relief port 105 and the radius of the foregoing discharge port 102 can be less than or equal to the radius of the circular arc end of the arc-shaped groove, so that on the one hand, the pressure relief groove 203 can be matched with the discharge port 102 and the pressure relief port 105, and on the other hand, the stress concentration of the second valve core part 200 can be reduced, which is beneficial to improve the structural reliability of the second valve core part 200 and prolong the service life of the second valve core part 200. Correspondingly, the two ends of the foregoing material passing groove 201 in the radial direction of the second valve core part 200 can also be in the form of a circular arc, and the radius of the foregoing pressure relief port 105 and the radius of the foregoing discharge port 102 can be less than or equal to the radius of the circular arc end of the material passing groove 201.

[0102] It can be understood that the foregoing air passing groove 202 can also be an arc-shaped groove.

[0103] As shown in the drawings, Figures 4 to 17 in a possible implementation, the gas inlet port 103 and the gas outlet port 104 are arranged at intervals along the circumferential direction of the material inlet port 101, and the gas inlet port 103 and the gas outlet port 104 are located on the same circumference of the first valve core part 100, the circumference where the gas inlet port 103 is located is different from the circumference where the discharge port 102 is located; the air passing groove 202 is formed along the circumferential direction of the second valve core part 200.

[0104] In this technical solution, the foregoing gas inlet port 103 and the foregoing gas outlet port 104 can also be arranged around the circumferential direction of the material inlet port 101 and located on the same circumference of the first valve core part 100. Correspondingly, the foregoing air passing groove 202 can be formed along the circumferential direction of the second valve core part 200, so that in the process of rotating the second valve core part 200, the foregoing air passing groove 202 can pass through the foregoing gas inlet port 103 and the gas outlet port 104, and when the slot of the air passing groove 202 is connected to the foregoing gas inlet port 103 and the foregoing gas outlet port 104 at the same time, the foregoing gas inlet port 103 can be connected to the foregoing gas outlet port 104 through the air passing groove 202, so as to guide the gaseous material to flow to the corresponding flow path through the valve body device, and realize the control of the gaseous material. At the same time, on the first valve core part 100, the circumference where the gas inlet port 103 is located is different from the circumference where the discharge port 102 is located, so as to avoid the air passing groove 202 from connecting the discharge port 102 and / or the pressure relief port 105, which is beneficial to ensure the operation stability and reliability of the valve body device.

[0105] It can be understood that the radial spacing between the air passing groove 202 and the center of the second valve core part 200 can be consistent with the radial spacing between the gas inlet port 103 or the gas outlet port 104 and the material inlet port 101, so as to facilitate the pressure relief groove 203 to pass through the foregoing discharge port 102 and the pressure relief port 105 in the process of rotating the second valve core part 200.

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

[0107] In this technical solution, the aforementioned first valve core 100 can be provided with the aforementioned feed inlet 101, discharge outlet 102, air inlet 103, air outlet 104 and pressure relief outlet 105 along its own axial direction. Thus, the aforementioned ports can be connected in a relatively straight manner, which is beneficial to improving the throughput of the aforementioned ports and reducing the resistance of material passage. Furthermore, the circumferential radius of the air inlet 103 can be set to be larger than the circumferential radius of the discharge outlet 102. This prevents the material passage groove 201 from accidentally connecting to the air inlet 103 or the air outlet 104 during the rotation of the second valve core 200, which is beneficial to further ensure the reliability of the valve body device when performing flow path control.

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

[0109] In this technical solution, the diameters of the inlet 101, outlet 102, and pressure relief port 105 can be set to be the same. This ensures, on the one hand, that by maintaining the same diameters for the inlet 101 and outlet 102, the flow velocity consistency at the inlet 101 and outlet 102 can be improved, preventing significant velocity changes in the material as it flows through the valve body. This, in turn, helps maintain stable internal pressure in the valve body when it performs any operating task, improving the operational stability and reliability of the valve body. Furthermore... On the one hand, by further setting the diameters of the inlet 101, outlet 102, and pressure relief port 105 to be the same, it is easier to match the inlet 101, outlet 102, and pressure relief port 105 with the material passage 201 and pressure relief groove 203, which helps to simplify the structure of the material passage 201 and pressure relief groove 203. At the same time, during the processing of the first valve core 100, it is easier to open the inlet 101, outlet 102, and pressure relief port 105 based on the same specification of processing tools, which helps to further reduce the processing cost of the valve body device.

[0110] In the technical solution, the diameter of the gas inlet 103 and the diameter of the gas outlet 104 can be set to be the same, so on the one hand, the consistency of the flow rate at the gas inlet 103 and the gas outlet 104 can be improved, the flow rate of the gaseous material can be prevented from changing greatly during the flow through the valve body device, the internal pressure of the valve body device can be kept stable, and the operation stability and reliability of the valve body device can be improved; on the other hand, during the processing of the first valve core part 100, the gas inlet 103 and the gas outlet 104 can be easily opened based on the same specification of processing tools, and the processing cost of the valve body device can be further reduced.

[0111] In the technical solution, the diameter of the feeding port 101, the diameter of the discharging port 102, and the diameter of the pressure relief port 105 can be set to be greater than the diameter of the gas inlet 103, and the diameter of the feeding port 101, the diameter of the discharging port 102, and the diameter of the pressure relief port 105 can be set to be greater than the diameter of the gas outlet 104, so that the diameters of the gas inlet 103 and the gas outlet 104 can be relatively small, which is beneficial to ensuring that the gaseous material has a high flow rate and pressure during gas supply, and thus the dispensing efficiency of the gaseous material can be improved.

[0112] As shown in Figure 5 In a feasible implementation, a plurality of discharging ports 102 are arranged at a preset interval angle θ around the circumference of the feeding port 101, and the pressure relief port 105 is arranged at 0.5 times the preset interval angle θ apart from the adjacent discharging port 102, and the preset interval angle satisfies:

[0113] θ≤360° / a

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

[0115] In the technical solution, when a plurality of aforementioned discharging ports 102 are arranged at intervals along the circumference of the feeding port 101, the adjacent discharging ports 102 can be kept at a preset interval angle θ, so that when the second valve core part 200 switches between the working positions, the rotation angle can be an integer multiple of the aforementioned preset interval angle θ, which is beneficial to improving the convenience and accuracy of the rotation control of the second valve core part 200, reducing the error of the second valve core part 200 when switching between the working positions, and further ensuring the stable and reliable pressure relief and flow path on-off control of the valve body device.

[0116] Meanwhile, when a pressure relief port 105 needs to be arranged between two adjacent discharging ports 102, the pressure relief port 105 can be arranged at 0.5 times the preset interval angle θ apart from the adjacent discharging port 102, so that when switching between the first pressure relief position and the working position, the second valve core part 200 can also rotate at a relatively fixed rotation angle, further ensuring the stable and reliable execution of the pressure relief process.

[0117] It can be understood that, as shown in Figure 5 the aforementioned preset interval angle θ can be the angle of the central angle with the first valve core part 100 axis position as the center, and the two sides of the aforementioned central angle pass through the axes of the two adjacent discharge ports 102.

[0118] Exemplarily, as shown in Figure 5 the valve body device can have four discharge ports 102, and the preset interval angle θ between the two adjacent discharge ports 102 can be less than or equal to 90°. Considering the uniformity of the distribution of the discharge ports 102 along the circumference of the first valve core part 100, the preset interval angle θ can be set to be equal to 90°.

[0119] In some feasible examples, the valve body device can further include a driving part. The driving part can be a driving device capable of outputting rotation, such as a motor or a motor. 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 use convenience of the valve body device. Exemplarily, the aforementioned driving part can be a stepper motor. The stepper motor can output small-angle rotation and has high parking flexibility, which is beneficial to improve the rotation stability of the second valve core part 200 and improve the action accuracy of the second valve core part 200 in 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 output control convenience of the driving part in actual application.

[0120] It can be understood that, in the case where the driving part is the aforementioned stepper motor, the aforementioned preset interval angle can be an even multiple of the step angle of the stepper motor. Correspondingly, the preset interval angle θ of 0.5 times can be an integer multiple of the aforementioned step angle.

[0121] As shown in Figure 7 in a feasible implementation, along the circumference of the second valve core part 200, the material passing groove 201 and the pressure relief groove 203 are arranged at a preset interval angle θ of 0.5 times, and the pressure relief groove 203 is located on the side of the material passing groove 201 away from the rotation direction.

[0122] In this technical solution, along the circumference of the second valve core part 200, the material passing groove 201 and the pressure relief groove 203 are arranged at a preset interval angle θ of 0.5 times, and the pressure relief groove 203 is located on the side of the material passing groove 201 away from the rotation direction of the second valve core part 200. Therefore, based on the aforementioned setting, after the valve body device completes the work task in the current working position, the second valve core part 200 can be rotated by 0.5 times of the aforementioned preset interval angle in the rotation direction, 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 passing groove 201, that is, the second valve core part 200 enters the first pressure relief position, and the pressure relief of the feed port 101 is realized.

[0123] In the case that the second valve core part 200 is rotated from the aforementioned current working position to the adjacent first pressure relief position, the pressure relief groove 203 can be located at the discharge port 102 corresponding to the aforementioned current working position at the same time, so that by setting the opening length of the pressure relief groove 203 along the circumferential direction of the second valve core part 200, for example, in the case that the pressure relief groove 203 is an arc-shaped groove, the central angle corresponding to the aforementioned arc-shaped groove can be greater than or equal to 0.5 times the preset interval angle and less than the preset interval angle, and in the case that the discharge port 102 corresponding to the aforementioned current working position also has a pressure relief port 105 on the side opposite to the aforementioned rotation direction, the discharge port 102 corresponding to the aforementioned current working position can be relieved through the pressure relief groove 203, that is, part of the second pressure relief position can coincide with the first pressure relief position, so as to facilitate the synchronous pressure relief of the inlet port 101 and the discharge port 102 after the valve body device completes the working task of the current working position, and to facilitate the improvement of the timeliness of the pressure relief of the discharge port 102, thereby providing further protection for the stable and reliable operation of the valve body device.

[0124] In an available implementation, the first valve core part 100 is further formed with a first communication groove 106, a plurality of second communication grooves 107, and a pressure relief channel 108, wherein the first communication groove 106 is arranged around the inlet port 101, one end of each second communication groove 107 is communicated with one pressure relief port 105, and the other end is communicated with the first communication groove 106, and one end of the pressure relief channel 108 is communicated with one of the plurality of pressure relief ports 105.

[0125] In this technical solution, the aforementioned first valve core part 100 can be further formed with a first communication groove 106, a second communication groove 107, and a pressure relief channel 108, wherein the aforementioned first communication groove 106 is arranged around the aforementioned inlet port 101, the number of the aforementioned second communication grooves 107 is plural, each of the aforementioned pressure relief ports 105 is communicated with the aforementioned first communication groove 106 through one second communication groove 107, so that in the case that the number of the pressure relief ports 105 is more than one, the plurality of pressure relief ports 105 can be communicated with each other through the aforementioned first communication groove 106 and the second communication groove 107, one end of the pressure relief channel 108 is communicated with one of the plurality of pressure relief ports 105, and the other end is used to communicate with the atmosphere, so that based on the aforementioned setting mode, when the second valve core part 200 is in each pressure relief position, it can be relieved through the aforementioned 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, facilitating the release of the internal pressure of the valve body device, and facilitating the reduction of the number of through holes of the first valve core part 100, thereby further ensuring the structural strength of the first valve core part 100 and prolonging the service life of the first valve core part 100.

[0126] It can be understood that one of the plurality of aforementioned pressure relief ports 105 is directly communicated with the aforementioned pressure relief channel 108, and the remaining pressure relief ports 105 are indirectly communicated with the aforementioned pressure relief channel 108 through the first communication groove 106 and the second communication groove 107; thus, when processing the first valve core part 100, the aforementioned pressure relief channel 108 and the aforementioned pressure relief port 105 directly communicated with the aforementioned pressure relief channel 108 can be formed by means of opening a through hole on the first valve core part 100, and the remaining pressure relief ports 105 can be blind holes with openings facing the second valve core part 200, thereby reducing the number of through holes opened on the first valve core part 100.

[0141] As shown in the drawings, in an available embodiment, the gas outlet 104 is in communication with one of the plurality of discharge ports 102. Figure 4

[0142] In this technical solution, the gas outlet 104 can be in communication with one of the plurality of discharge ports 102, so that in actual application, the discharge port 102 can be set as a through hole penetrating the first valve core part 100, and the gas outlet 104 is set as a blind hole with an open end facing the second valve core part 200 and in communication with one of the plurality of discharge ports 102, that is, gaseous material can be output through the discharge port 102 in communication with the gas outlet 104, which is beneficial to reduce the number of through holes on the first valve core part 100, improve the structural reliability of the first valve core part 100, and reduce the processing cost of the first valve core part 100.

[0143] It can be understood that in combination with the foregoing, in actual application, the gas inlet 103 and the gas outlet 104 can be located on the same circumference of the first valve core part 100, and the discharge port 102 and the pressure relief port 105 can be located on the same circumference of the valve core part, and the circumference where the gas inlet 103 is located is different from the circumference where the pressure relief port 105 is located, so as to avoid the through air groove 202 in communication with the discharge port 102 and the pressure relief port 105.

[0144] As shown in the drawings, in an available embodiment, at least one of the plurality of discharge ports 102 is an arc-shaped port 102a circumferentially arranged on the first valve core part 100, and the arc-shaped port 102a corresponds to a first working position and a second working position; wherein, when the second valve core part 200 is in the first working position, the second valve core part 200 covers the gas inlet 103 and / or the gas outlet 104; when the second valve core part 200 is in the second working position, the gas inlet 103 is in communication with the gas outlet 104 through the through air groove 202.

The arc direction of the arc-shaped port 102a is consistent with the circumferential direction of the first valve core 100. Correspondingly, the working position corresponding to the arc-shaped port 102a can include two working positions. When the second valve core 200 is in the first working position or the second working position, the feed port 101 can be connected to the arc-shaped port 102a through the material passage 201. When the second valve core 200 is in the first working position, the second valve core 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 200 is in the second working position, the air inlet 103 is connected to the air outlet 104 through the air passage 202, so that the valve body device can output different types of materials simultaneously through one discharge port 102 and one air outlet 104, thereby improving the flexibility of the valve body device in the material feeding process and helping to further simplify the flow path system of the beverage machine.

[0146] For example, in conjunction with the aforementioned example of applying the valve body device to a coffee machine, the outlet 102 corresponding to the working position M3 can be set as an arc-shaped outlet 102a. Correspondingly, the arc-shaped outlet 102a is used to connect to the foaming device of the coffee machine.

Therefore, based on the aforementioned settings, the valve body device can be applied to the coffee machine or coffee making process to control the flow path between the foaming device, the steam generator and the air supply device.

[0153] Meanwhile, the first valve core part 100 is further formed with an air inlet 103 and an air outlet 104, and the second valve core part 200 is further formed with an air passage groove 202, one of the plural working positions is an air injection station, and accordingly, when the second valve core part 200 is in the air injection station, the air inlet 103 and the air inlet 103 can be communicated through the air passage groove 202.

[0154] It can be understood that, as shown in Figure 9 , Figure 11 , Figure 13 , Figure 14 and Figure 16 , in the case that the second valve core part 200 is in any working position, the material outlet 102 corresponding to the working position can be communicated with the material inlet 101 through the material passage groove 201, and the other material outlets 102 not having a corresponding relationship with the working position are cut off from the material inlet 101; as shown in Figure 10 , Figure 12 , Figure 15 and Figure 17 , in the case that the second valve core part 200 is not in the working position, the material inlet 101 and any material outlet 102 are in a cut-off state.

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. The gas supply device may be used to output air. The air inlet 103 of the valve body device may be connected to the gas supply device, and the air output by the gas supply device may be supplied to the foaming device.

[0157] For example, such as Figures 9 to 17 As shown, the first valve core 100 may have four discharge ports 102 and one inlet port 101, and the second valve core 200 may have a material passage 201 connected to the aforementioned inlet port 101.

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.
