Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0083] As Figures 1 to 4As shown, according to the first aspect of the embodiments of the present application, a valve body device is provided, which comprises: a valve body part 100, which is formed with a feed flow path 101 and a plurality of discharge flow paths 102; a valve core part 200, which is rotatably arranged in the valve body part 100, and which is formed with a reset position and a plurality of working positions along a rotation direction, each working position corresponding to one discharge flow path 102, and in the case that the valve core part 200 is in a working position, the corresponding discharge flow path 102 is connected to the feed flow path 101; a driving part 300, which is used to drive the valve core part 200 to rotate, and which comprises a position detection assembly 340, which is used to generate reset information in the case that the valve core part 200 is in the reset position; and a detection part 400, which is used to detect rotation information of the driving part 300, so as to determine a rotation angle of the valve core part 200 according to the rotation information.

[0084] The valve body device provided by the embodiments of the present application comprises the valve body part 100, the valve core part 200, the driving part 300 and the detection part 400, wherein the valve body part 100 is formed with the feed flow path 101 and the discharge flow path 102, so that the material in the flow path system can flow through the valve body device through the feed flow path 101 and the discharge flow path 102, the number of the discharge flow paths 102 is plural, and the driving part 300 can switch the valve core part 200 between different working positions by driving the valve core part 200 to rotate relative to the valve body part 100, so as to change the on-off state of the plurality of flow paths, and in actual application, the valve body device can distribute the received material to different external devices to realize multi-way integrated control, which is beneficial to reduce the use amount of valve components of the equipment to which the valve body device is applied, and simplify the flow path system of the equipment.

[0085] The driving part 300 comprises the position detection assembly 340, the valve core part 200 further has the reset position, and the position detection assembly 340 is used to generate reset information in the case that the valve core part 200 is in the reset position, so as to facilitate understanding of the position state of the valve core part 200 during use of the valve body device, and the position of the valve core part 200 can be corrected through the position detection assembly 340, so as to reduce the position error accumulation amount of the valve core part 200 during use; the detection part 400 is used to detect the rotation information of the driving part 300, and determine the rotation angle of the valve core part 200 according to the rotation information, which is beneficial to improve the rotation control accuracy of the valve core part 200, and provides guarantee for the valve body device to stably and reliably perform flow path control.

[0086] It can be understood that the aforementioned rotation information can include but is not limited to the output rotation speed, output torque, rotation angle, etc. of the driving part 300; the valve core part 200 is easy to contact the material during use, so in actual application, the valve core part 200 can be arranged in the valve body part 100 and in a relatively closed environment to avoid material leakage or pollution. By determining the rotation angle of the valve core part 200 through the aforementioned rotation information, direct rotation detection of the valve core part 200 can be avoided, which is beneficial to improve the detection convenience of the rotation angle of the valve core part 200 and improve the rotation stability of the valve core part 200.

[0087] Exemplarily, in the process of driving the valve core part 200 from the current position to the target working position by the driving part 300, the rotation control of the valve core part 200 can be performed based on the aforementioned reset position, that is, in the process of driving the valve core part 200 from the current position to the target working position by the driving part 300, the valve core part 200 can be driven from the current position to the reset position and then from the reset position to the target working position. In the case where the target working position is known, based on the angular interval between the target working position and the reset position, the rotation angle requirement of the valve core part 200 from the reset position to the target working position can be determined, and the actual rotation angle of the valve body device starting from the reset position is detected by the detection part 400. Further, in the case where the rotation angle detected by the detection part 400 meets the aforementioned rotation angle requirement, the valve core part 200 can be guaranteed to rotate to the aforementioned target working position, avoiding the reduction of the rotation control precision of the valve core part 200 caused by error accumulation, providing protection for the stable and accurate flow path control of the valve body device, and ensuring the stable and smooth operation of the aforementioned beverage making device in the case where the valve body device is applied to the beverage making device.

[0088] It can be understood that in some examples, when the valve core of the multi-way valve switches positions, the actual rotation angle of the valve core often has a certain error from the required value, and as the number of position switching increases, the aforementioned error will also accumulate and increase, thereby causing the control precision of the valve core rotation to decrease and the control reliability of the multi-way valve to the flow path to decrease. The valve body device provided in the embodiment of the present application can determine the position of the valve core part 200 by the position detection assembly 340 in the process of driving the valve core part 200 from the current position to the target working position by the driving part 300, thereby facilitating the position correction of the valve core part 200, and at the same time, the actual rotation angle of the valve core part 200 can be detected by the detection part 400, which is beneficial to realize the accurate control of the rotation of the valve core part 200 and provide protection for the stable and accurate flow path control of the valve body device.

[0089] It can be understood that the valve body device provided by the embodiments of the present application is applied to a device with a flow path system, such as a fluid machine, a hydraulic machine and the like, and can also be applied to a beverage making device, such as a coffee machine, a tea machine, a milk tea machine, a sparkling water machine and the like, thereby facilitating simplification of the flow path system of the corresponding device or device, reducing the use amount of valve components of the corresponding device or device, and ensuring the accuracy and reliability of flow path control.

[0090] As shown in Figure 1 illustratively, the foregoing valve core part 200 can include a first valve core 210 and a second valve core 220, wherein the foregoing first valve core 210 can be formed with a feed inlet 2101 and a plurality of discharge outlets 2102, the foregoing feed inlet 2101 is communicated with the foregoing feed flow path 101, the foregoing discharge outlet 2102 is one-to-one correspondingly communicated with the foregoing second valve core 220 which is rotatably arranged in the foregoing first valve core 210 and is formed with a material passing groove 2201, the foregoing feed inlet 2101 is communicated with the foregoing material passing groove 2201, the second valve core 220 has the foregoing plurality of working positions, each working position corresponds to one of the foregoing discharge outlets 2102, in the case that the second valve core 220 is in the foregoing working position, the foregoing feed inlet 2101 can be conducted to the corresponding discharge outlet 2102 through the material passing groove 2201, thereby conducting the corresponding discharge flow path 102.

[0091] It can be understood that in the case that the valve core part 200 is not in the foregoing working position, the feed inlet 2101 and the discharge outlet 2102 are in a cut-off state, and correspondingly, each discharge flow path 102 is also in a cut-off state.

[0092] It can be understood that in the case that the foregoing valve core part 200 includes the foregoing first valve core 210 and the foregoing second valve core 220, the foregoing driving part 300 is used to drive the foregoing second valve core 220 to rotate relative to the first valve core 210, that is, the foregoing second valve core 220 can be connected to the foregoing driving part 300 to rotate relative to the first valve core 210 under the driving of the driving part 300.

[0093] It can be understood that the foregoing driving part 300 can include a driving member 310 for outputting rotation, the foregoing driving member 310 can be but is not limited to a motor, a motor and the like, for example, can be a stepper motor, a servo motor and the like; the foregoing driving member 310 can be directly connected to the foregoing valve core part 200 to save driving energy, or can be connected to the valve core part 200 through a transmission mechanism to improve the stability and reliability of the valve core part 200 when rotating through the transmission mechanism, and to ensure that the valve core part 200 and the driving member 310 have a relatively stable transmission ratio, so as to further improve the rotation control precision of the valve core part 200.

[0094] As shown in Figures 1 to 4As shown, in an embodiment, the driving part 300 comprises a driving member 310, a first transmission member 320 connected to the valve core part 200, and a second transmission member 330 connected between the driving member 310 and the first transmission member 320. The detecting part 400 is configured to detect the rotation information of the driving member 310 or the rotation information of the second transmission member 330.

[0095] In the technical scheme, the driving part 300 can comprise the driving member 310, the first transmission member 320, and the second transmission member 330. The first transmission member 320 is connected to the valve core part 200. The second transmission member 330 is connected between the first transmission member 320 and the driving member 310. The driving member 310 is configured to provide power. When the driving member 310 operates, the driving member 310 can drive the second transmission member 330 and the first transmission member 320 to move in sequence, and drive the valve core part 200 to rotate through the second transmission member 330, so as to realize the position switching of the valve core part 200. This is beneficial to improve the controllability of the valve body device. The first transmission member 320 and the second transmission member 330 can convert the rotation speed and the torque output by the driving member 310 and apply them to the valve core part 200, which is beneficial to ensure the rotation stability of the valve core part 200. Based on the above arrangement, the driving part 300 can limit the transmission ratio between the driving member 310 and the valve core part 200 through the first transmission member 320 and the second transmission member 330, which is beneficial to realize the small-angle rotation control of the valve core part 200 and improve the rotation control accuracy of the valve core part 200.

[0096] Meanwhile, the detection part 400 is used for detecting the rotation information of the driving member 310 or the rotation information of the second transmission member 330, so as to determine the rotation angle of the valve core part 200 according to the rotation information of the driving member 310 or the rotation information of the second transmission member 330. Based on the above setting, on the one hand, in the case that the output rotation speed of the driving member 310 and the transmission ratio between the driving member 310 and the valve core part 200 are known, the rotation angle of the valve core part 200 can be determined through the rotation information of the driving member 310 or the rotation information of the second transmission member 330, avoiding the direct detection of the detection member 420, improving the convenience of the detection of the rotation angle of the valve core part 200, and being beneficial to improve the rotation stability of the valve core part 200. On the other hand, the first transmission member 320 is connected to the valve core part 200, so that the rotation state of the first transmission member 320 is close to the rotation state of the valve core part 200. Correspondingly, based on the transmission effect of the first transmission member 320 and the second transmission member 330, the output rotation speed of the driving member 310 and the rotation speed of the second transmission member 330 are both higher than the rotation speed of the valve core part 200. Further, in the case that the detection precision of the detection part 400 is certain, the rotation angle of the valve core part 200 is determined through the rotation information of the driving member 310 or the rotation information of the second transmission member 330, so that the result error in the determination of the rotation angle of the valve core part 200 can be greatly reduced, which is beneficial to further improve the rotation control precision of the valve core part 200, and provides further guarantee for the stable and reliable operation of the valve body device.

[0097] Exemplarily, in consideration of the stability of the driving of the valve core portion 200 by the driving portion 300, the transmission between the driving member 310 and the valve core portion 200 can be a speed reduction transmission, that is, the rotation speed of the valve core portion 200 is lower than the rotation speed of the driving member 310, and the rotation speeds of the driving member 310, the second transmission member 330 and the first transmission member 320 are successively reduced, the aforementioned detection portion 400 can be used to detect the rotation angle of the rotating member, the detection error of the detection portion 400 is ±1°, and the transmission ratio between the driving member 310 and the valve core portion 200 is taken as 10:1 for example, if the driving member 310 actually rotates 720°, then the theoretical rotation angle of the valve core portion 200 should be 72°, considering the influence of the detection precision of the detection portion 400, 1° of measurement error is generated, then the rotation angle of the valve core portion 200 directly detected by the detection portion 400 will be 71° or 73°, accordingly, the rotation angle of the driving member 310 is measured, then 719° or 721° of measurement result is obtained, thus based on the rotation information of the driving member 310 detected by the detection portion 400, the rotation angle measurement value of the valve core portion 200 is calculated in combination with the transmission ratio between the driving member 310 and the valve core portion 200, then 71.9° or 72.1° of measurement result is obtained, it is not difficult to understand that based on the aforementioned detection manner provided by the technical solution, the detection result error of the rotation angle of the valve core portion 200 can be greatly reduced, the rotation angle detection precision of the valve core portion 200 is improved, and further guarantee is provided for the stable and reliable operation of the valve body device.

[0098] Similarly, it can be understood that the determination of the rotation angle of the valve core portion 200 based on the rotation information of the second transmission member 330 can also reduce the detection error.

[0099] It can be understood that the aforementioned driving member 310 and the aforementioned valve core portion 200 can be transmitted in a relatively stable transmission ratio, for example, gear transmission, chain transmission, belt transmission and the like, accordingly, the first transmission member 320 and the second transmission member 330 can be different gears meshing with each other, different pulleys connected by a transmission belt or different sprockets connected by a chain and the like.

[0100] It can be understood that the number of the aforementioned second transmission member 330 can be greater than or equal to one, in the case that the number of the second transmission member 330 is more than one, each second transmission member 330 is successively connected, and at least one second transmission member 330 is connected to the driving member 310, and at least one second transmission member 330 is connected to the first transmission member 320, thereby facilitating further expansion of the transmission ratio between the driving member 310 and the valve core portion 200, and facilitating further improvement of the rotation stability and rotation control precision of the valve core portion 200.

[0101] For example, Figures 1 to 4As shown, in an available embodiment, the detection part 400 comprises a triggering member 410 and a detection member 420, one of the triggering member 410 and the detection member 420 is arranged on the driving member 310 or the second transmission member 330, so that the triggering member 410 rotates relative to the detection member 420, and the detection member 420 is used to detect the rotation amount of the triggering member 410 relative to the detection member 420, so as to determine the rotation information according to the rotation amount; wherein the triggering member 410 is arranged away from the detection member 420.

[0102] In the technical scheme, the detection part 400 can comprise the triggering member 410 and the detection member 420, one of the triggering member 410 and the detection member 420 can be arranged on the driving member 310 or the second transmission member 330, so that the triggering member 410 rotates relative to the detection member 420, and it can be understood that the one of the triggering member 410 and the detection member 420 arranged on the driving member 310 or the second transmission member 330 can rotate synchronously with the driving member 310 or the second transmission member 330, so that the detection member 420 can determine the rotation information of the driving member 310 or the first transmission member 320 by detecting the rotation amount of the triggering member 410 relative to the detection member 420, and then determine the rotation angle of the valve core part 200, so as to provide a reliable reference for the rotation control of the valve core part 200, and the arrangement position of the detection part 400 is relatively flexible, which is beneficial to further ensure the detection accuracy of the detection part 400 and provide more reliable protection for the stable operation of the valve body device.

[0103] Meanwhile, the triggering member 410 is arranged away from the detection member 420, which can avoid the direct contact between the triggering member 410 and the detection member 420 during the detection process, and accordingly, the triggering member 410 can trigger the detection member 420 in a non-contact manner, which is beneficial to reduce the possibility of structural damage and failure of the detection part 400, improve the detection accuracy of the detection part 400, and prolong the service life of the detection part 400.

[0104] Exemplarily, the triggering member 410 can be arranged on the driving member 310 or the second transmission member 330, or the detection member 420 can also be arranged on the driving member 310 or the second transmission member 330.

[0105] It can be understood that, in the case that the triggering member 410 is arranged on the driving member 310 or the second transmission member 330, the arrangement position of the detection member 420 can be set in combination with the position of the triggering member 410, so as to ensure that the detection member 420 and the triggering member 410 can rotate relative to each other and trigger. Accordingly, in the case that the detection member 420 is arranged on the driving member 310 or the second transmission member 330, the arrangement position of the triggering member 410 is the same, so as to ensure that the detection member 420 and the triggering member 410 can rotate relative to each other and trigger.

[0106] It can be understood that the rotation amount of the trigger 410 relative to the detection member 420 can include, but is not limited to, the rotation speed, the rotation angle, and the rotation number of the trigger 410 relative to the detection member 420, and the like.

[0107] In a feasible implementation, the detection part 400 further comprises a support member; one of the trigger 410 and the detection member 420 is arranged on the output shaft 311 of the driving member 310, and the other is arranged on the support member; or one of the trigger 410 and the detection member 420 is arranged on the second transmission member 330, and the other is arranged on the support member.

[0108] In the technical solution, the detection part 400 can further comprise a support member, one of the trigger 410 and the detection member 420 can be arranged on the output shaft 311 of the driving member 310, and the other can be arranged on the support member, for example, the trigger 410 can be arranged on the output shaft 311 of the driving member 310, and correspondingly, the detection member 420 can be arranged on the support member, or the detection member 420 can be arranged on the output shaft 311 of the driving member 310, and correspondingly, the trigger 410 can be arranged on the support member, so that when one of the trigger 410 and the detection member 420 rotates with the output shaft 311 of the driving member 310, relative rotation can be formed between the trigger 410 and the detection member 420, and the rotation amount of the trigger 410 relative to the detection member 420 can be obtained by the detection member 420, so as to obtain the rotation information of the driving member 310, provide a basis for determining the rotation angle of the valve core part 200, and at the same time, the detection part 400 can also use the support member to provide stable support for the trigger 410 or the detection member 420, ensure the smooth execution of the detection process, and is beneficial to improving the detection precision of the detection part 400.

[0109] Alternatively, one of the trigger 410 and the detection member 420 can be arranged on the second transmission member 330, and the other can be arranged on the support member, for example, the trigger 410 can be arranged on the second transmission member 330, and correspondingly, the detection member 420 can be arranged on the support member, or the detection member 420 can be arranged on the second transmission member 330, and correspondingly, the trigger 410 can be arranged on the support member, so that when one of the trigger 410 and the detection member 420 rotates with the second transmission member 330, relative rotation can be formed between the trigger 410 and the detection member 420, and the rotation amount of the trigger 410 relative to the detection member 420 can be obtained by the detection member 420, so as to obtain the rotation information of the second transmission member 330, provide a basis for determining the rotation angle of the valve core part 200, and at the same time, the detection part 400 can also use the support member to provide stable support for the trigger 410 or the detection member 420, ensure the smooth execution of the detection process, and is beneficial to improving the detection precision of the detection part 400.

[0110] It can be understood that in actual applications, the support member can be arranged on a fixed component of the device to which the valve body device is applied, so as to ensure that the detection member 420 and the triggering member 410 can rotate relative to each other and trigger, for example, a housing, a rack or the like of the aforementioned device, which is not limited here.

[0111] As shown in Figures 1 to 4 In a possible implementation, the output shaft 311 has a driving end and a free end, the driving end is connected to the second transmission member 330, and one of the triggering member 410 and the detection member 420 is arranged at the free end.

[0112] In the technical scheme, the output shaft 311 of the driving member 310 can have a driving end and a free end, and it can be understood that the driving end and the free end can be two opposite shaft ends of the output shaft 311. Correspondingly, the driving end can be used to connect to the second transmission member 330 to transmit power to the second driving member 310 when the driving member 310 operates, thereby driving the first driving member 310 and the valve core part 200 to rotate. One of the triggering member 410 and the detection member 420 can be arranged at the free end, so that the triggering member 410 or the detection member 420 can be relatively far away from the transmission part of the driving part 300, avoiding the detection member 420 or the triggering member 410 interfering with the operation of the driving part 300, which is beneficial to improve the operation stability of the detection part 400 and the driving part 300 and improve the rotation control precision of the valve core part 200.

[0113] In a possible implementation, the number of the second transmission members 330 is at least two, and the at least two second transmission members 330 are connected in sequence, and the triggering member 410 and the detection member 420 are arranged at adjacent two second transmission members 330, respectively.

[0114] In the technical scheme, the triggering member 410 and the detection member 420 can be arranged on adjacent two second transmission members 330, respectively. It can be understood that the transmission ratio between adjacent components in the transmission chain of the driving part 300 is fixed, so that based on the arrangement, according to the transmission ratio between the adjacent two second transmission members 330 and the rotation amount of the triggering member 410 relative to the detection member 420 detected by the detection member 420, the rotation information of the second transmission member 330 where the triggering member 410 is located can be determined, and then the rotation angle of the valve core part 200 is determined. Based on the above arrangement, the distribution area of the detection part 400 and the driving part 300 can be more concentrated, which is beneficial to further improve the structural compactness of the valve body device and improve the miniaturization level of the valve body device.

[0115] In an implementation, the trigger 410 is a magnetic element, and the detector 420 is a magnetic angle sensor; or the trigger 410 is a capacitive electrode, and the detector 420 is a capacitive sensor; or the detector 420 is a radar.

[0116] In this technical solution, the trigger 410 can be a magnetic element, and the detector 420 can be a magnetic angle sensor, so that when the trigger 410 rotates relative to the detector 420, the detector 420 can determine the rotation amount of the trigger 410 relative to the detector 420 by detecting the magnetic angle change information, to provide a reference for determining the rotation angle of the valve core 200, and based on the magnetic angle detection mode, the trigger 410 does not need to contact the detector 420, which is beneficial to maintain the distance between the trigger 410 and the detector 420, thereby reducing the contact between the trigger 410 and the detector 420, improving the detection accuracy and service life of the detection part 400, and the magnetic angle detection has low sensitivity to environmental parameters, which is beneficial to further ensure the accuracy of the detection result of the rotation angle of the valve core 200.

[0117] It can be understood that in the case where the valve body device is applied to a beverage making device, dust and mist may exist in the environment where the valve body device is located, and in some examples, the rotation amount is detected by a photoelectric switch, but the photoelectric switch is greatly affected by the above-mentioned environmental factors, and is prone to signal distortion under the influence of voltage fluctuation. Magnetic angle detection has low sensitivity to the above-mentioned environmental influence, which is beneficial to perform more accurate detection work in the above-mentioned environment, and the detection accuracy is less affected by voltage fluctuation.

[0118] In this technical solution, the trigger 410 can also be a capacitive electrode, and the detector 420 can correspondingly be a capacitive sensor, so that when the trigger 410 rotates relative to the detector 420, the trigger 410 can also detect the detector 420 in a non-contact manner, so that the detector 420 detects the rotation amount of the trigger 410 relative to the detector 420, thereby reducing the contact between the trigger 410 and the detector 420, improving the detection accuracy and service life of the detection part 400, and the capacitive detection has low sensitivity to environmental parameters, which is beneficial to further ensure the accuracy of the detection result of the rotation angle of the valve core 200.

[0119] In the technical scheme, the detection member 420 can be a radar, in the case where the detection member 420 is a radar, the type requirement of the trigger member 410 is relatively low, the trigger member 410 can be a reference object or a reference structure capable of being recognized by the radar, for example, can be a convex or concave structure and the like, so that based on the foregoing setting, in the case where the trigger member 410 rotates relative to the detection member 420, the trigger member 410 can also trigger the detection member 420 in a non-contact manner, so that the detection member 420 detects the rotation amount of the trigger member 410 relative to the detection member 420, thereby reducing the contact between the trigger member 410 and the detection member 420, improving the detection precision and service life of the detection part 400, and the radar can detect the rotation amount by radio waves, and the sensitivity to environmental parameters is low, which is beneficial to further ensure the detection result precision of the rotation angle of the valve core part 200.

[0120] In an available embodiment, the magnetic angle sensor is a Hall sensor.

[0121] In the technical scheme, in the case where the detection member 420 is a magnetic angle sensor and the trigger member 410 is a magnetic member, the magnetic angle sensor can adopt a Hall sensor, the Hall sensor has small volume and light weight, which is beneficial to further improve the light weight and small size level of the valve body device, and the Hall sensor has high installation convenience, low power consumption during operation, and can further reduce the production and use cost of the valve body device, and the Hall sensor has good motion detection performance, and the requirement for the use environment is also relatively low, which is beneficial to ensure the rotation angle detection precision of the valve core part 200.

[0122] As shown in Figures 1 to 4 In an available embodiment, in the case where the trigger member 410 is a magnetic member and the detection member 420 is a magnetic angle sensor, the driving member 310 comprises: an output shaft 311 connected to the second transmission member 330; a mounting disc 312 arranged at one end of the output shaft 311 away from the second transmission member 330, the mounting disc 312 is coaxially arranged with the output shaft 311, and a mounting groove is formed on the side of the mounting disc 312 away from the output shaft 311; wherein the magnetic member is embedded in the mounting groove, and the side of the mounting disc 312 away from the output shaft 311 is arranged towards the magnetic angle sensor.

[0123] In the technical solution, in the case that the detection member 420 is a magnetic angle sensor and the trigger member 410 is a magnetic member, the driving member 310 can include an output shaft 311 and a mounting disc 312, wherein the output shaft 311 is used for power output, that is, one end of the output shaft 311 can be connected to the second transmission member 330, and the mounting disc 312 is arranged at the end of the output shaft 311 away from the second transmission member 330, that is, the mounting disc 312 can be arranged at the free end of the output shaft 311, so that the mounting disc 312 can rotate synchronously with the output shaft 311 in the case that the output shaft 311 rotates, and a mounting groove can be formed on the side of the mounting disc 312 away from the output shaft 311, and correspondingly, the magnetic member can be arranged in the mounting groove, so that the magnetic member can rotate synchronously with the mounting disc 312, and the magnetic angle sensor can be arranged towards the side of the mounting disc 312 away from the output shaft 311, so as to facilitate the magnetic member to act on the magnetic angle sensor and facilitate the magnetic angle sensor to detect the rotation amount of the mounting disc 312, thereby providing a reference for determining the rotation angle of the valve core part 200. At the same time, based on the above arrangement, the trigger member 410 and the detection member 420 can be relatively away from the transmission part of the driving part 300, so as to avoid the detection member 420 or the trigger member 410 interfering with the operation of the driving part 300, thereby improving the operation stability of the detection part 400 and the driving part 300 and improving the rotation control precision of the valve core part 200.

[0124] As shown in Figures 1 to 4 In a possible implementation, the first transmission member 320 and the second transmission member 330 each include a gear.

[0125] In the technical solution, the first transmission member 320 and the second transmission member 330 each include a gear, that is, the rotation speed and torque can be transmitted between the driving member 310 and the valve core part 200 in a gear transmission manner, so that on the one hand, the rotation stability of the gear transmission is high, which is beneficial to the transmission of the motion amount in the form of rotation, thereby being beneficial to improving the rotation speed stability of the valve core part 200 and ensuring the smooth rotation of the valve core part 200; on the other hand, the transmission ratio of the gear transmission is fixed, which is beneficial to determining the rotation angle of the valve core part 200 according to the rotation information of the driving member 310 or the second transmission member 330 and facilitating the accurate control of the rotation parameters of the valve core part 200, thereby further ensuring the stable and reliable operation of the valve body device.

[0126] It can be understood that the specific form of the gear can be but is not limited to a spur gear, a bevel gear, a helical gear, a worm gear, a worm, etc., and the specific form of the gear can be set according to actual needs, which is not limited here.

[0127] As shown in Figures 1 to 4As shown, in one feasible embodiment, the second transmission member 330 includes a worm, a worm wheel, and a first gear, and the first transmission member 320 includes a second gear. The worm is connected to the output shaft 311 of the drive member 310 and is coaxially arranged with the output shaft 311. The worm wheel meshes with the worm. The first gear is disposed on the worm wheel and is coaxially arranged with the worm wheel. The second gear meshes with the first gear. The second gear is connected to the valve core 200.

[0128] In this technical solution, the number of the aforementioned second transmission components 330 can be multiple, and the multiple second transmission components 330 may include a worm, a worm wheel, and a first gear. The worm can be coaxially connected to the output shaft 311 of the aforementioned drive component 310, so that when the output shaft 311 rotates, the worm can rotate synchronously. The worm wheel meshes with the worm, so that the motion output by the output shaft 311 can be preferentially converted through worm gear transmission, which helps to reduce the rotational speed and increase the torque, thereby providing a reliable power foundation for driving the valve core 200. The first gear can be connected to the aforementioned drive component 310. The worm gear is arranged coaxially, so it can rotate synchronously with the worm gear. The first transmission member 320 may include a second gear, which meshes with the first gear and is connected to the valve core 200. Thus, the power output by the drive member 310 can be further converted through the first gear and the second gear, and then acted on the valve core 200 through the second gear. This helps to further increase the transmission ratio between the drive member 310 and the valve core 200, making it easier for the valve core 200 to rotate at small angles, improving the rotation control accuracy of the valve core 200, and enhancing the rotation stability of the valve core 200.

[0129] It is understood that the specific forms of the aforementioned first gear and the aforementioned second gear can be, but are not limited to, spur gears, bevel gears, helical gears, etc. The specific forms of the aforementioned first gear and the aforementioned second gear can be set according to actual needs, and no further restrictions are imposed here.

[0130] like Figures 1 to 4 As shown, in one feasible embodiment, the position detection component 340 includes: an identification disk 341 disposed on the first transmission member 320, wherein the identification disk 341 rotates synchronously with the valve core 200 when the first transmission member 320 rotates; and an identification member 342, wherein the identification disk 341 is provided with a position mark 3411, and the identification member 342 is used to identify the position mark 3411; wherein the identification member 342 is configured to generate reset information when the position mark 3411 is identified.

[0131] In this technical solution, the aforementioned detection component may include an identification disk 341 and an identification element 342. The identification disk 341 is disposed on the aforementioned first transmission member 320, so that when the aforementioned first transmission member 320 rotates, the identification disk 341 can rotate synchronously with the aforementioned first transmission member 320. The identification disk 341 is provided with a position mark 3411, and correspondingly, the position mark 3411 can also rotate synchronously with the identification disk 341. The aforementioned identification element 342 is used to identify the aforementioned position mark 3411 and generate reset information of the valve core 200 when the position mark 3411 is identified. Therefore, based on the aforementioned configuration, during use, when the aforementioned identification element 342 identifies the aforementioned position mark 3411 and generates the aforementioned position information, it can be directly determined that the valve core 200 is in the aforementioned reset position, which facilitates the positioning and correction of the valve core 200 during use, provides a reference for the operation control of the motor body, and helps to further improve the accuracy and convenience of the rotation control of the valve core 200, and provides further guarantee for the stable and smooth operation of the valve body device.

[0132] It is understandable that, in practical applications, the position mark 3411 can be matched with the working position of the valve core 200 during the assembly of the valve body device. For example, the position mark 3411 can be set to correspond to one of the multiple working positions of the valve core 200. That is, the reset position can be one of the multiple aforementioned working positions, which is beneficial to further improve the positioning convenience of the valve core 200.

[0133] like Figures 1 to 4 As shown, in one possible implementation, the position marker 3411 is a protrusion formed on the periphery of the marker disk 341, and the identification element 342 is a micro switch.

[0134] In this technical solution, the aforementioned position mark 3411 can be a protruding structure disposed on the outer peripheral wall of the aforementioned mark disk 341, and the aforementioned identification element 342 can be a micro switch. Thus, as the aforementioned position mark 3411 rotates with the mark disk 341, the aforementioned identification element 342 can be triggered by touch to generate reset information. This helps to simplify the structure of the position detection component 340, reduce the cost of using the position detection component 340, and ensure the detection reliability of the position detection component 340.

[0135] like Figure 1 As shown, in some feasible examples, the valve body device may also include a sealing part 500, which is disposed between the valve core part 200 and the valve body part 100 to seal the gap between the valve body part 100 and the valve core part 200, reduce the possibility of material leakage, and improve the cleanliness and safety of the valve body device.

[0136] According to a second aspect of the embodiments of the present application, a beverage machine is provided, comprising the valve body device according to any one of the first aspect.

[0137] The beverage machine provided by the embodiments of the present application can comprise the valve body device according to any one of the first aspect, so that the on-off control of the flow path can be performed by the valve body device, which is beneficial to simplify the flow path system of the beverage machine, improve the flow path control integration of the beverage machine, and further improve the miniaturization level and light weight level of the beverage machine. Meanwhile, the position switching accuracy of the valve core part 200 of the valve body device is relatively high, which is beneficial to ensure the stable and reliable operation of the beverage machine.

[0138] In a feasible implementation manner, the beverage machine further comprises: a brewing device, at least one of the plurality of discharge flow paths 102 is communicated with the brewing device; a liquid outlet device, at least one of the plurality of discharge flow paths 102 is communicated with the liquid outlet device; a foaming device, at least one of the plurality of discharge flow paths 102 is communicated with the foaming device.

[0139] In this technical solution, the beverage machine can be used as a coffee machine in actual application. The brewing device can be used to brew coffee powder, so that when coffee making is needed, the valve core part 200 can be rotated to the working position corresponding to the brewing device to supply hot water for brewing coffee powder into the brewing device. The liquid outlet device can be used to output liquid, so that when the beverage machine needs to output the shell, the valve core part 200 can be rotated to the working position corresponding to the liquid outlet device to output the liquid through the liquid outlet device. The foaming device can be used to make milk foam, so that when milk foam is made, the valve core part 200 can be rotated to the working position corresponding to the foaming device to supply liquid and / or gaseous material for making milk foam to the milk foam device.

[0140] In some feasible examples, the beverage machine can further comprise a liquid heating device, which can be used to heat water and can be used to output hot water or steam. The inlet flow path 101 of the valve body device can be communicated with the output end of the liquid heating device, so that when the coffee machine needs to brew coffee powder, make milk foam, or directly output hot water, hot water or steam can be supplied to the corresponding device through the valve body device.

[0141] In addition, since the beverage machine provided by the embodiments of the present application comprises the valve body device according to any one of the first aspect, it has all the beneficial effects of the valve body device, which will not be repeated here.

[0142] As shown in Figure 5 According to a third aspect of the embodiments of the present application, a control method of a beverage machine is provided, which is used to control the beverage machine according to any one of the second aspect, and the control method comprises:

[0143] Step S101: in response to the start instruction, the control driving part 300 drives the valve core part 200 to rotate until the reset detection assembly 340 generates the reset information.

[0144] Specifically, in the case that the beverage receives the aforementioned start instruction, the start instruction can be responded to, and the driving part 300 of the valve body device is controlled to operate to drive the valve core part 200 of the valve body device to rotate by the driving part 300 until the reset detection assembly of the driving part 300 generates the aforementioned reset information, so that the valve core part 200 is in the reset position, so as to determine the position state of the valve core part 200, realize the position determination and calibration of the valve core part 200, and provide a reference for the subsequent position switching of the valve core part 200.

[0145] It can be understood that the aforementioned start instruction can be an electrical signal for controlling the beverage machine to start; in actual application, the beverage machine can be configured with an instruction receiving assembly, for example, a button, a key, etc., and the aforementioned start instruction can be automatically generated after the beverage machine is powered on, or can be issued through the aforementioned instruction receiving assembly, which is not limited here.

[0146] Step S102: in response to the operation mode instruction, the control driving part 300 drives the valve core part 200 to rotate to the target working position; wherein the target working position is one of the plurality of working positions.

[0147] Specifically, the aforementioned operation mode instruction can be used to control the beverage machine to operate in a certain operation mode, in combination with the setting of the aforementioned valve body device, the aforementioned operation mode instruction can be various, and each working position of the valve core part 200 corresponds to an operation mode instruction. In the case that the beverage machine receives the aforementioned operation mode instruction, the operation mode instruction can be responded to, and the driving part 300 is controlled to operate to drive the valve core part 200 to rotate by the driving part 300, drive the valve core part 200 to rotate from the reset position to the target working position. It can be understood that the target working position is the working position corresponding to the aforementioned operation mode instruction, and then the beverage machine can pass through the corresponding flow path through the valve body device to realize the dispensing of the material or the output of the beverage.

[0148] Exemplarily, in the case that the aforementioned beverage machine comprises a brewing device, a liquid outlet device and a milk frothing device, the aforementioned operation mode instruction can also correspondingly comprise a brewing instruction, a liquid outlet instruction and a milk frothing instruction, in the case that the aforementioned operation mode instruction is the brewing instruction, the spool part 200 can be controlled to rotate to a working position corresponding to the aforementioned brewing device, so that the material can flow to the brewing device through the valve body device; in the case that the aforementioned operation mode instruction is the liquid outlet instruction, the spool part 200 can be controlled to rotate to a working position corresponding to the aforementioned liquid outlet device, so that the material can flow to the liquid outlet device through the valve body device; in the case that the aforementioned operation mode instruction is the milk frothing instruction, the spool part 200 can be controlled to rotate to a working position corresponding to the aforementioned brewing device, so that the material can flow to the milk frothing device through the valve body device.

[0149] In summary, the control method of the beverage machine provided by the embodiments of the present application can rotate the spool part 200 of the valve body device to the reset position when the beverage machine is started, and can control the rotation of the spool part 200 based on the reset position, that is, in the process of driving the spool part 200 to rotate from the current position to the target working position by the driving part 300, the spool part 200 can be rotated from the current position to the reset position and from the reset position to the target working position, so as to avoid the reduction of the rotation control precision of the spool part 200 caused by error accumulation, and to provide guarantee for the stable and accurate flow path control of the valve body device, and in the case that the valve body device is applied to a beverage making device, the stable and smooth operation of the aforementioned beverage making device is ensured.

[0150] In a feasible implementation manner, in response to the operation mode instruction, the step of controlling the driving part 300 to drive the spool part 200 to rotate to the target working position comprises:

[0151] determining the target working position according to the operation mode instruction;

[0152] controlling the driving part 300 to operate to drive the spool part 200 to rotate;

[0153] controlling the detection part 400 to operate to determine the rotation angle of the spool part 200;

[0154] controlling the driving part 300 to stop in the case that the rotation angle reaches the target rotation angle;

[0155] wherein the target rotation angle is equal to the included angle between the reset position and the target working position along the rotation direction.
