[0082] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0083] like Figures 1 to 4As shown, according to the first aspect of the embodiment of the present application, a valve body device is proposed, including: a valve body portion 100, formed with a feed flow path 101 and a plurality of discharge flow paths 102; a valve core portion 200, rotatably arranged on the valve body portion 100, the valve core portion 200 is formed with a reset position and a plurality of working positions along the rotation direction, each working position corresponds to a discharge flow path 102, and when the valve core portion 200 is in the working position, the corresponding discharge flow path 102 is connected to the feed flow path 101; a driving portion 300, used to drive the valve core portion 200 to rotate, the driving portion 300 includes a position detection component 340, when the valve core portion 200 is in the reset position, the position detection component 340 is used to generate reset information; a detection portion 400, used to detect the rotation information of the driving portion 300, so as to determine the rotation angle of the valve core portion 200 according to the rotation information.

[0084] The valve body device provided in the embodiment of the present application includes a valve body portion 100, a valve core portion 200, a drive portion 300 and a detection portion 400, wherein the valve body portion 100 is formed with a feed flow path 101 and a 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 multiple, and the drive portion 300 can switch the valve core portion 200 between different working positions by driving the valve core portion 200 to rotate relative to the valve body portion 100, thereby changing the on-off state of the multiple flow paths. Further, in actual applications, the valve body device can distribute the received materials to different external devices to realize multi-channel integrated control, which is beneficial to reducing the use of valve components of the equipment used by the valve body device and simplifying the flow path system of the aforementioned equipment.

[0085] The aforementioned driving part 300 includes a position detection component 340, and the aforementioned valve core part 200 also has a reset position. The aforementioned position detection component 340 is used to generate reset information when the valve core part 200 is located at the aforementioned reset position, so as to facilitate understanding of the position state of the valve core part 200 during the use of the valve body device, and the position of the valve core part 200 can be corrected by the position detection component 340 to reduce the accumulated position error of the valve core part 200 during use; the aforementioned 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 aforementioned rotation information, which is beneficial to improve the rotation control accuracy of the valve core part 200 and provide a guarantee for the valve body device to stably and reliably perform flow control.

[0086] It can be understood that the aforementioned rotation information may include but is not limited to the output speed, output torque, rotation angle, etc. of the driving part 300; since the valve core part 200 is easy to contact the material during use, in actual applications, 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 contamination. 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 improving the convenience of detecting the rotation angle of the valve core part 200, and is beneficial to improving the rotation stability of the valve core part 200.

[0087] Exemplarily, in the process of using the driving unit 300 to drive the valve core part 200 to rotate from the current position to the target working position, the rotation of the valve core part 200 can be controlled based on the aforementioned reset position, that is, in the process of using the driving unit 300 to drive the valve core part 200 to rotate from the current position to the target working position, the valve core part 200 can be rotated from the current position to the reset position, and then rotated from the reset position to the target working position. When 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 can be detected by the detection unit 400. Then, when the rotation angle detected by the detection unit 400 meets the aforementioned rotation angle requirement, it can ensure that the valve core part 200 rotates to the aforementioned target working position, avoid the reduction of the rotation control accuracy of the valve core part 200 due to error accumulation, provide a guarantee for the valve body device to stably and accurately control the flow path, and when the valve body device is applied to a beverage making device, ensure the smooth operation of the aforementioned beverage making device.

[0088] It is understandable that in some examples, when the valve core of the multi-way valve is switching positions, the actual rotation angle of the valve core often has a certain error with the required value, and as the number of position switching increases, the aforementioned error will also accumulate and increase, thereby resulting in a decrease in the control accuracy of the valve core rotation and a decrease in the reliability of the multi-way valve's control of the flow path. Based on the aforementioned setting, the valve body device provided in the embodiment of the present application can determine the position of the valve core part 200 through the position detection component 340 in the process of using the driving part 300 to drive the valve core part 200 to rotate from the current position to the target working position, 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 conducive to realizing accurate control of the rotation of the valve core part 200, and providing a guarantee for the valve body device to stably and accurately control the flow path.

[0089] It can be understood that the valve body device provided in the embodiment of the present application is applied to equipment with a flow system, such as fluid machinery, hydraulic machinery, etc., and can also be applied to beverage making devices, such as coffee machines, tea machines, milk tea machines, sparkling water machines, etc., thereby helping to simplify the flow system of the corresponding equipment or devices, while reducing the use of valve components of the corresponding equipment or devices, ensuring the accuracy and reliability of flow control.

[0090] like Figure 1 As shown, exemplarily, the valve core portion 200 may include a first valve core 210 and a second valve core 220, wherein the first valve core 210 may be formed with a feed port 2101 and a plurality of discharge ports 2102, the feed port 2101 being connected to the feed flow path 101, the discharge ports 2102 being connected one-to-one to the second valve core 220 being rotatably disposed on the first valve core 210, and being formed with a feed slot 2201, the feed port 2101 being connected to the feed slot 2201, the second valve core 220 having the plurality of working positions, each working position corresponding to one of the discharge ports 2102, and when the second valve core 220 is in the plurality of working positions, the feed port 2101 may be connected to the corresponding discharge port 2102 through the feed slot 2201, thereby allowing the corresponding discharge flow path 102 to be connected.

[0091] It can be understood that when the valve core part 200 is not in the aforementioned working position, the feed port 2101 and the discharge port 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, when the aforementioned valve core part 200 includes the aforementioned first valve core 210 and the aforementioned second valve core 220, the aforementioned driving part 300 is used to drive the aforementioned second valve core 220 to rotate relative to the first valve core 210, that is, the aforementioned second valve core 220 can be connected to the aforementioned driving part 300 so as to rotate relative to the first valve core 210 under the drive of the driving part 300.

[0093] It can be understood that the aforementioned driving part 300 may include a driving member 310 for outputting rotation, and the aforementioned driving member 310 may be but not limited to a motor, a motor, etc., for example, it may be a stepping motor, a servo motor, etc.; the aforementioned driving member 310 may be directly connected to the aforementioned valve core part 200 to save driving energy consumption, and may also be connected to the valve core part 200 through a transmission mechanism, so as to improve the stability and reliability of the valve core part 200 during rotation through the transmission mechanism, and ensure that there is a relatively stable transmission ratio between the valve core part 200 and the driving member 310, so as to further improve the rotation control accuracy of the valve core part 200.

[0094] like Figures 1 to 4As shown, in a feasible implementation manner, the driving part 300 includes: a driving member 310; a first transmission member 320, connected to the valve core part 200; a second transmission member 330, connected between the driving member 310 and the first transmission member 320; wherein the detection part 400 is used to detect the rotation information of the driving member 310 or the rotation information of the second transmission member 330.

[0095] In this technical solution, the driving part 300 may include a driving member 310, a first transmission member 320 and a second transmission member 330, wherein the first transmission member 320 is connected to the valve core part 200, and the second transmission member 330 is connected between the first transmission member 320 and the driving member 310, and the driving member 310 is used to provide power. When the driving member 310 is running, 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 to realize the valve. The position switching of the core portion 200 is beneficial to improving the operational controllability of the valve body device, and the first transmission member 320 and the second transmission member 330 can convert the rotation speed and torque output by the driving member 310 and apply them to the valve core portion 200, which is beneficial to ensuring the rotation stability of the valve core portion 200. Based on the aforementioned arrangement, the driving portion 300 can limit the transmission ratio between the driving member 310 and the valve core portion 200 through the first transmission member 320 and the second transmission member 330, which is beneficial to achieving small-angle rotation control of the valve core portion 200 and improving the rotation control accuracy of the valve core portion 200.

[0096] At the same time, the aforementioned detection part 400 is used to detect 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 aforementioned 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 aforementioned setting, on the one hand, when the output 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 driven by the rotation information of the driving member 310 or the rotation information of the second transmission member 330, avoiding direct detection by the detection member 420, thereby improving the convenience of detecting the rotation angle of the valve core part 200 and facilitating improving the rotation stability of the valve core part 200; on the other hand, the first transmission Since the member 320 is connected to the valve core part 200, the rotation state of the first transmission member 320 is close to the rotation state of the valve core part 200. Accordingly, based on the transmission action of the first transmission member 320 and the second transmission member 330, the output speed of the driving member 310 and the speed of the second transmission member 330 are both higher than the speed of the valve core part 200. Then, when the detection accuracy of the detection part 400 is constant, the rotation angle of the valve core part 200 is determined by the rotation information of the driving member 310 or the rotation information of the second transmission member 330. This can greatly reduce the result error when determining the rotation angle of the valve core part 200, which is beneficial to further improve the rotation control accuracy of the valve core part 200 and provide further guarantee for the stable and reliable operation of the valve body device.

[0097] Exemplarily, considering the stability of the driving part 300 when driving the valve core part 200 to rotate, the transmission between the driving member 310 and the valve core part 200 can be a reduction transmission, that is, the rotation speed of the valve core part 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 part 400 can be used to detect the rotation angle of the rotating part. Taking the detection error of the detection part 400 as ±1° and the transmission ratio between the driving member 310 and the valve core part 200 as 10:1 as an example, if the driving member 310 actually rotates 720°, then the theoretical rotation angle of the valve core part 200 should be 72°. Considering that the detection part 400 has a measurement error of 1° due to the influence of the detection accuracy, If the rotation angle of the valve core part 200 is different, then directly detecting the rotation angle of the valve core part 200 through the detection part 400 will obtain a measurement result of 71° or 73°. Correspondingly, measuring the rotation angle of the driving member 310 will obtain a measurement result of 719° or 721°. Therefore, based on the rotation information of the driving member 310 detected by the detection part 400 and the transmission ratio between the driving member 310 and the valve core part 200, the rotation angle measurement value of the valve core part 200 is calculated, and a measurement result of 71.9° or 72.1° is obtained. It is not difficult to understand that the aforementioned detection method provided based on the technical solution can greatly reduce the detection result error of the rotation angle of the valve core part 200, improve the detection accuracy of the rotation angle of the valve core part 200, and provide further guarantee for the stable and reliable operation of the valve body device.

[0098] Similarly, it can be understood that determining 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 part 200 can be transmitted in a relatively stable transmission ratio manner, such as gear transmission, chain transmission, belt transmission, etc. Correspondingly, the first transmission member 320 and the second transmission member 330 can be different gears that mesh with each other, different pulleys connected by a transmission belt, or different sprockets connected by a chain, etc.

[0100] It can be understood that the number of the aforementioned second transmission members 330 can be greater than or equal to one. When the number of the second transmission members 330 is more than one, the second transmission members 330 are connected in sequence, 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, which is beneficial to further expand the transmission ratio between the driving member 310 and the valve core part 200, and is beneficial to further improve the rotation stability and rotation control accuracy of the valve core part 200.

[0101] like Figures 1 to 4As shown, in a feasible implementation manner, the detection part 400 includes: a trigger member 410 and a detection member 420, one of the trigger member 410 and the detection member 420 is arranged on the driving member 310 or the second transmission member 330, so that the trigger member 410 rotates relative to the detection member 420, and the detection member 420 is used to detect the rotation amount of the trigger member 410 relative to the detection member 420, so as to determine the rotation information according to the rotation amount; wherein, the trigger member 410 and the detection member 420 are arranged separately.

[0102] In this technical solution, the aforementioned detection part 400 may include a trigger member 410 and a detection member 420, wherein one of the aforementioned trigger member 410 and the aforementioned detection member 420 may be arranged on the aforementioned driving member 310 or the aforementioned second transmission member 330, so that the trigger member 410 rotates relative to the detection member 420, and it can be understood that the aforementioned trigger member 410 and the aforementioned detection member 420, whichever is 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 aforementioned rotation information of the driving member 310 or the first transmission member 320 by detecting the rotation amount of the trigger 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 conducive to further ensuring the detection accuracy of the detection part 400, and is conducive to providing more reliable guarantee for the smooth operation of the valve body device.

[0103] At the same time, the trigger member 410 and the detection member 420 are arranged separately, which can avoid direct contact between the trigger member 410 and the detection member 420 during the detection process. Accordingly, the trigger 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 unit 400, improve the detection accuracy of the detection unit 400, and extend the service life of the detection unit 400.

[0104] Exemplarily, the trigger member 410 may be disposed on the driving member 310 or the second transmission member 330 , or the detection member 420 may be disposed on the driving member 310 or the second transmission member 330 .

[0105] It is understandable that, in the case where the trigger member 410 is disposed on the driving member 310 or the second transmission member 330, the setting position of the detection member 420 can be set in combination with the position of the trigger member 410, so as to ensure that the detection member 420 and the trigger member 410 can rotate relative to each other and trigger each other. Correspondingly, in the case where the detection member 420 is disposed on the driving member 310 or the second transmission member 330, the setting position of the trigger member 410 is similar, so as to ensure that the detection member 420 and the trigger member 410 can rotate relative to each other and trigger each other.

[0106] It is understandable that the rotation amount of the trigger member 410 relative to the detection member 420 may include but is not limited to the rotation speed, rotation angle, and number of rotations of the trigger member 410 relative to the detection member 420 .

[0107] In a feasible embodiment, the detection part 400 also includes a support member; one of the trigger member 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 member 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 this technical solution, the detection unit 400 may further include a support member, and one of the trigger member 410 and the detection member 420 may be arranged on the output shaft 311 of the driving member 310, and the other may be arranged on the support member. For example, the trigger member 410 may be arranged on the output shaft 311 of the driving member 310, and correspondingly, the detection member 420 may be arranged on the support member, or the detection member 420 may be arranged on the output shaft 311 of the driving member 310, and correspondingly, the trigger member 410 may be arranged on the support member, so that When one of the triggering member 410 and the aforementioned detecting member 420 rotates following the output shaft 311 of the driving member 310, relative rotation can be formed between the triggering member 410 and the detecting member 420, and the rotation amount of the triggering member 410 relative to the detecting member 420 is obtained through the detecting member 420, so as to obtain the rotation information of the driving member 310, and provide a basis for determining the rotation angle of the valve core part 200. At the same time, the detecting part 400 can also use the supporting member to provide stable support for the triggering member 410 or the detecting member 420, so as to ensure the smooth execution of the detection process, which is beneficial to improve the detection accuracy of the detecting part 400.

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

[0110] It can be understood that in actual applications, the support member can be set on the fixed part of the equipment used by the valve body device to ensure that the detection member 420 and the trigger member 410 can rotate relative to each other and trigger. For example, it can be the shell, frame, etc. of the aforementioned equipment, and no further restrictions are made here.

[0111] like Figures 1 to 4 As shown, in a feasible implementation manner, 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 trigger member 410 and the detection member 420 is disposed at the free end.

[0112] In this technical solution, the output shaft 311 of the aforementioned driving member 310 can have a driving end and a free end. It can be understood that the aforementioned driving end and the aforementioned free end can be two opposite shaft ends of the aforementioned output shaft 311. Accordingly, the aforementioned driving end can be used to connect to the second transmission member 330, so as to transmit power to the second driving member 310 when the driving member 310 is running, thereby driving the first driving member 310 and the valve core part 200 to rotate. One of the aforementioned trigger member 410 and the aforementioned detection member 420 can be arranged at the aforementioned free end, so that the trigger 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 trigger member 410 from interfering with the operation of the driving part 300, which is beneficial to improving the operating stability of the detection part 400 and the driving part 300, and improving the rotation control accuracy of the valve core part 200.

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

[0114] In this technical solution, the trigger member 410 and the detection member 420 can be respectively arranged on two adjacent second transmission members 330. It can be understood that the transmission ratio between the adjacent components on the transmission chain of the drive unit 300 is fixed. Based on the aforementioned arrangement, according to the transmission ratio between the two adjacent second transmission members 330 and the rotation amount of the trigger member 410 detected by the detection member 420 relative to the detection member 420, the rotation information of the second transmission member 330 where the trigger member 410 is located can be determined, and then the rotation angle of the valve core part 200 can be determined. Based on the aforementioned arrangement, the distribution area of ​​the detection part 400 and the drive 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 a feasible implementation manner, the triggering member 410 is a magnetic member, and the detecting member 420 is a magnetic angle sensor; or the triggering member 410 is a capacitive electrode, and the detecting member 420 is a capacitive sensor; or the detecting member 420 is a radar.

[0116] In this technical solution, the trigger member 410 can be a magnetic member, and the detection member 420 can be a magnetic angle sensor, so that when the trigger member 410 rotates relative to the detection member 420, the detection member 420 can determine the rotation amount of the trigger member 410 relative to the detection member 420 by detecting the magnetic angle change information, so as to provide a reference for determining the rotation angle of the valve core part 200, and based on the magnetic angle detection method, there is no need to require the trigger member 410 to contact the detection member 420, which is beneficial to maintain the distance between the trigger member 410 and the detection member 420, thereby reducing the contact between the trigger member 410 and the detection member 420, and improving the detection accuracy and service life of the detection part 400, and the magnetic angle detection is less sensitive to environmental parameters, which is beneficial to further ensure the accuracy of the detection result of the rotation angle of the valve core part 200.

[0117] It is understandable that when 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. In some examples, the rotation amount is detected by a photoelectric switch, but the photoelectric switch is greatly affected by the aforementioned environmental factors and is prone to signal distortion under the influence of voltage fluctuations. Magnetic angle detection is less sensitive to the aforementioned environmental influences, which is conducive to performing more precise detection operations in the aforementioned environment, and the detection accuracy is less affected by voltage fluctuations.

[0118] In this technical solution, the trigger member 410 can also be a capacitive electrode, and the detection member 420 can correspondingly be a capacitive sensor. Thus, when 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 can detect 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, thereby improving the detection accuracy and service life of the detection part 400, and the capacitive detection is less sensitive to environmental parameters, which is beneficial to further ensure the accuracy of the detection result of the rotation angle of the valve core part 200.

[0119] In this technical solution, the aforementioned detection member 420 can be a radar. In the case where the aforementioned detection member 420 is a radar, the requirements for the type of the trigger member 410 are relatively low. The aforementioned trigger member 410 can be a reference object or reference structure that can be identified by the radar, for example, it can be a protrusion or a recessed structure, etc., so that based on the aforementioned setting, when 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 can detect 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, and improving the detection accuracy and service life of the detection part 400. In addition, the radar can detect the rotation amount through radio waves, and has a low sensitivity to environmental parameters, which is conducive to further ensuring the accuracy of the detection result of the rotation angle of the valve core part 200.

[0120] In a feasible implementation manner, the magnetic angle sensor is a Hall sensor.

[0121] In this technical solution, when the aforementioned detection member 420 is a magnetic angle sensor and the aforementioned trigger member 410 is a magnetic member, the aforementioned magnetic angle sensor can adopt a Hall sensor. The Hall sensor is small in size and light in weight, which is conducive to further improving the lightweight and miniaturization level of the valve body device. The Hall sensor is easy to install and has low power consumption during operation, which can further reduce the production and use costs of the valve body device. At the same time, the Hall sensor has good motion detection performance and relatively low requirements for the use environment, which is conducive to ensuring the rotation angle detection accuracy of the valve core part 200.

[0122] like Figures 1 to 4 As shown, in a feasible implementation manner, when the trigger member 410 is a magnetic member and the detection member 420 is a magnetic angle sensor, the driving member 310 includes: an output shaft 311, connected to the second transmission member 330; a mounting disk 312, arranged at the end of the output shaft 311 away from the second transmission member 330, the mounting disk 312 is coaxially arranged with the output shaft 311, and a mounting groove is formed on the side of the mounting disk 312 away from the output shaft 311; wherein the magnetic member is embedded in the mounting groove, and the side of the mounting disk 312 away from the output shaft 311 is arranged toward the magnetic angle sensor.

[0123] In this technical solution, when the detection member 420 is a magnetic angle sensor and the trigger member 410 is a magnetic member, the driving member 310 may include an output shaft 311 and a mounting plate 312, wherein the output shaft 311 is used for power output, that is, one end of the output shaft 311 may be connected to the second transmission member 330, and the mounting plate 312 is arranged at an end of the output shaft 311 away from the second transmission member 330, that is, the mounting plate 312 may be arranged at the free end of the output shaft 311, so that when the output shaft 311 rotates In this case, the aforementioned mounting disk 312 can rotate synchronously with the aforementioned output shaft 311, and a mounting groove can be formed on the side of the mounting disk 312 away from the aforementioned output shaft 311. Accordingly, the aforementioned magnetic member can be arranged in the aforementioned mounting groove, so that the magnetic member can rotate synchronously with the aforementioned mounting disk 312, and the magnetic angle sensor can be arranged toward the side of the mounting disk 312 away from the aforementioned output shaft 311, so that the magnetic member can trigger the magnetic angle sensor, so that the magnetic angle sensor can detect the rotation amount of the mounting disk 312, and provide a reference for determining the rotation angle of the valve core part 200. At the same time, based on the aforementioned arrangement, the trigger member 410 and the detection member 420 can also be relatively far 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, which is conducive to improving the operating stability of the detection part 400 and the driving part 300, and improving the rotation control accuracy of the valve core part 200.

[0124] like Figures 1 to 4 As shown, in a feasible implementation manner, the first transmission member 320 and the second transmission member 330 both include gears.

[0125] In this technical solution, the aforementioned first transmission member 320 and the aforementioned second transmission member 330 may both include gears, that is, the rotation speed and torque can be transmitted between the driving member 310 and the valve core part 200 by means of gear transmission. Therefore, on the one hand, the rotational stability of the gear transmission is relatively high, which is conducive to the transmission of motion in the form of rotation, and further helps to improve the rotational speed stability of the valve core part 200, and ensure the smooth rotation of the valve core part 200; on the other hand, the transmission ratio of the gear transmission is fixed, which is conducive 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 facilitates the precise control of the rotation parameters of the valve core part 200, thereby providing further guarantee for the stable and reliable operation of the valve body device.

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

[0127] like Figures 1 to 4As shown, in a 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, wherein the worm is connected to the output shaft 311 of the driving member 310, and the worm is coaxially arranged with the output shaft 311, the worm wheel is meshed with the worm, the first gear is arranged on the worm wheel, and the first gear is coaxially arranged with the worm wheel, and the second gear is meshed with the first gear; wherein the second gear is connected to the valve core portion 200.

[0128] In this technical solution, the number of the second transmission member 330 can be multiple, and the multiple second transmission members 330 can include a worm, a worm wheel and a first gear, wherein the worm can be coaxially connected to the output shaft 311 of the driving member 310, so that when the output shaft 311 rotates, the worm can rotate synchronously, and the worm wheel is meshed with the worm, so that the motion output by the output shaft 311 can be preferentially converted by worm gear transmission, which is conducive to reducing the rotation speed and increasing the torque, thereby providing a reliable power basis for the drive of the valve core part 200; the first gear can be connected with the front The worm gear is coaxially arranged so that it can rotate synchronously with the aforementioned worm gear. The first transmission member 320 may include a second gear, and the aforementioned second gear is meshed with the aforementioned first gear, and the aforementioned second gear is connected to the valve core part 200, so that the power output by the driving member 310 can be further converted through the first gear and the second gear, and act on the valve core part 200 through the second gear, which is beneficial to further increase the transmission ratio between the driving member 310 and the valve core part 200, facilitate the valve core part 200 to rotate at a small angle, improve the rotation control accuracy of the valve core part 200, and enhance the rotation stability of the valve core part 200.

[0129] It can be 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 excessive restrictions are made here.

[0130] like Figures 1 to 4 As shown, in a feasible embodiment, the position detection component 340 includes: an identification disk 341, which is arranged on the first transmission member 320, and when the first transmission member 320 rotates, the identification disk 341 rotates synchronously with the valve core part 200; an identification member 342, 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 member 342, wherein the aforementioned identification disk 341 is arranged 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, and the identification disk 341 is provided with a position mark 3411, and accordingly, the position mark 3411 can also rotate synchronously with the identification disk 341; the aforementioned identification member 342 is used to identify the aforementioned position mark 3411, and is used to generate reset information of the valve core part 200 when the position mark 3411 is identified; therefore, based on the aforementioned setting, during use, when the aforementioned identification member 342 identifies the aforementioned position mark 3411 and generates the aforementioned position information, it can be directly determined that the valve core part 200 is in the aforementioned reset position, which is convenient for positioning and correcting the valve core part 200 during use, providing a reference for the operation control of the motor body, which is conducive to further improving the accuracy and convenience of the rotation amount control of the valve core part 200, and providing further guarantee for the smooth operation of the valve body device.

[0132] It can be understood that in actual applications, when the valve body device is assembled, the position mark 3411 can be matched with the working position of the valve core part 200. For example, the position mark 3411 can be set to correspond to one of the multiple working positions of the valve core part 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 part 200.

[0133] like Figures 1 to 4 As shown, in a feasible implementation manner, the position mark 3411 is a protrusion formed on the peripheral side of the identification plate 341, and the identification member 342 is a micro switch.

[0134] In this technical solution, the aforementioned position mark 3411 can be a protruding structure arranged on the outer peripheral wall of the aforementioned identification disk 341, and the aforementioned identification member 342 can be a micro switch, so that the aforementioned position mark 3411 can trigger the aforementioned identification member 342 by touch during the process of following the rotation of the identification disk 341, so that the aforementioned identification member 342 generates reset information, which is helpful to simplify the structure of the position detection component 340, reduce the use cost of 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 further include a sealing portion 500, which is disposed between the valve core portion 200 and the valve body portion 100, and is used to seal the gap between the valve body portion 100 and the valve core portion 200, thereby reducing the possibility of material leakage and helping to improve the cleanliness and safety of the valve body device.

[0136] According to a second aspect of an embodiment of the present application, a beverage machine is provided, comprising: a valve body device as provided in any one of the above-mentioned first aspects.

[0137] The beverage machine provided in the embodiment of the present application may include a valve body device as proposed in any one of the first aspects above, so that the on-off control of the flow path can be performed through the aforementioned valve body device, which is conducive to simplifying the flow path system of the beverage machine, improving the integration of the flow path control of the beverage machine, and further improving the miniaturization level and lightweight level of the beverage machine. At the same time, the position switching accuracy of the valve core part 200 of the aforementioned valve body device is high, which is conducive to ensuring the stable and reliable operation of the beverage machine.

[0138] In a feasible embodiment, the beverage machine also includes: a brewing device, at least one of the multiple discharge flow paths 102 is connected to the brewing device; a liquid discharge device, at least one of the multiple discharge flow paths 102 is connected to the liquid discharge device; and a foaming device, at least one of the multiple discharge flow paths 102 is connected to the foaming device.

[0139] In this technical solution, the beverage machine can be used as a coffee machine in actual applications, and the brewing device can be used to brew coffee powder, so that when coffee needs to be made, the valve core part 200 can be rotated to a working position corresponding to the brewing device to dispense hot water for brewing coffee powder into the brewing device; the liquid outlet device can be used to output liquid, and if the beverage machine needs to output the shell to the outside, the valve core part 200 can be rotated to a working position corresponding to the liquid outlet device to output the liquid through the liquid outlet device; the frothing device can be used to make milk froth, so when making milk froth, the valve core part 200 can be rotated to a working position corresponding to the frothing device to dispense liquid material and / or gaseous material for making milk froth to the milk frothing device.

[0140] In some feasible examples, the beverage machine may also include a liquid heating device, which can be used to heat water and output hot water or steam. The feed flow path 101 of the valve body device can be connected to 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, the hot water or steam can be distributed to the corresponding device through the valve body device.

[0141] In addition, since the beverage machine provided in the embodiment of the present application includes the valve body device as proposed in any one of the first aspects above, it has all the beneficial effects of the valve body device, which will not be described in detail here.

[0142] like Figure 5 As shown, according to a third aspect of an embodiment of the present application, a control method of a beverage machine is proposed, which is used to control the beverage machine proposed in any one of the second aspects above, and the control method includes:

[0143] Step S101: in response to a start instruction, the driving unit 300 is controlled to drive the valve core unit 200 to rotate until the position detection component 340 generates reset information;

[0144] Specifically, when the beverage receives the aforementioned start-up instruction, it can respond to the start-up instruction and control the operation of the driving part 300 of the valve body device, so as to drive the valve core part 200 of the valve body device to rotate through the driving part 300, until the reset detection component of the driving part 300 generates the aforementioned reset information, so that the valve core part 200 can be placed 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-up instruction can be an electrical signal for controlling the start-up of the beverage machine; in actual applications, the beverage machine can be configured with a command receiving component, such as a button, a key, etc. The aforementioned start-up instruction can be automatically generated after the beverage machine is powered on, or it can be issued through the aforementioned command receiving component, and no further restrictions are made here.

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

[0147] Specifically, the aforementioned operating mode instruction can be used to control the beverage machine to operate in a certain operating mode. Combined with the setting of the aforementioned valve body device, the aforementioned operating mode instructions can be multiple, and the working position of each valve core part 200 corresponds to an operating mode instruction. When the beverage machine receives the aforementioned operating mode instruction, it can respond to the operating mode instruction and control the operation of the driving part 300 to drive the valve core part 200 to rotate through the driving part 300, and 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 operating mode instruction, and then the beverage machine can conduct the corresponding flow path through the valve body device to achieve material distribution or beverage output.

[0148] Exemplarily, in the case where the beverage machine includes a brewing device, a liquid discharge device and a foaming device, the operating mode instruction may also correspondingly include a brewing instruction, a liquid discharge instruction and a milk foam instruction. In the case where the operating mode instruction is a brewing instruction, the valve core portion 200 may be controlled to rotate to a working position corresponding to the brewing device so that the material may flow to the brewing device through the valve body device; in the case where the operating mode instruction is a liquid discharge instruction, the valve core portion 200 may be controlled to rotate to a working position corresponding to the liquid discharge device so that the material may flow to the liquid discharge device through the valve body device; in the case where the operating mode instruction is a milk foam instruction, the valve core portion 200 may be controlled to rotate to a working position corresponding to the brewing device so that the material may flow to the foaming device through the valve body device.

[0149] In summary, the control method of the beverage machine provided in the embodiment of the present application can rotate the valve core part 200 of the valve body device to the reset position when the beverage machine is started, and can control the rotation of the valve core part 200 based on the reset position, that is, in the process of using the driving part 300 to drive the valve core part 200 to rotate from the current position to the target working position, the valve core part 200 can be rotated from the current position to the reset position, and from the reset position to the target working position, thereby avoiding the reduction of the rotation control accuracy of the valve core part 200 due to error accumulation, providing a guarantee for the valve body device to stably and accurately control the flow path, and when the valve body device is applied to the beverage making device, ensuring the smooth operation of the aforementioned beverage making device.

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

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

[0152] Control the driving part 300 to operate so as to drive the valve core part 200 to rotate;

[0153] Controlling the detection unit 400 to operate so as to determine the rotation angle of the valve core unit 200;

[0154] When the rotation angle reaches the target rotation angle, the driving unit 300 is controlled to stop;

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

[0156] Specifically, in the process of controlling the driving unit 300 to drive the valve core unit 200 to rotate to the target working position in response to the operation mode instruction, the target working position can be determined based on the operation mode instruction, so as to determine the target rotation angle required for the valve core unit 200 to rotate from the reset position to the target working position according to the target working position. In the process of driving the valve core unit 200 to rotate by the driving unit 300, the detection unit 400 can be controlled to determine the rotation angle of the valve core unit 200, so as to understand the actual rotation angle of the valve core unit 200. Then, when the rotation angle reaches the target rotation angle, the driving unit 300 can be controlled to stop, so that the valve core unit 200 stays at the aforementioned target working position to perform the material dispensing operation corresponding to the working position; thus, based on the detection of the actual rotation angle of the valve core unit 200 by the detection unit 400, it is convenient to timely grasp the position of the valve core unit 200 during the rotation process, which is conducive to realizing precise control of the rotation of the valve core unit 200, and thus providing guarantee for the smooth operation of the valve body device and the beverage machine.
