Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0078] The present invention provides an embodiment of an integrated valve, primarily for use in water purification equipment, which is primarily used to purify water and provide healthy drinking water. The integrated valve can control the on / off and flow direction of multiple waterways in the water system of the water purification equipment, thereby reducing the number of solenoid valves or electric valves used in the water system.

[0079] See also Figures 1 to 8 In one embodiment of the present invention, the integrated valve 10 includes a valve body 100 and a valve core assembly 200; the valve body 100 has a accommodating cavity 110, a first water outlet 120 and at least two second water outlets 130, and the first water outlet 120 and the second water outlet 130 are both connected to the accommodating cavity 110; the valve core assembly 200 is movably arranged in the accommodating cavity 110, for switching to connect the first water outlet 120 and at least one of the second water outlets 130; the integrated valve 10 has a first mode and a second mode, when the integrated valve 10 is in the first mode, the first water outlet 120 and any one of the second water outlets 130 are independently connected; when the integrated valve 10 is in the second mode, the first water outlet 120 and any two adjacent second water outlets 130 are connected.

[0080] Specifically, the valve body 100 has a accommodating cavity 110. The shape of the accommodating cavity 110 can be cylindrical, rectangular, or other shapes. The valve body 100 is made of a hard material. As for the type of the hard material, it can be a hard material such as ABS, HIPS, PP, PC, ceramic, or a metal or alloy material, etc. There is no specific limitation here. The accommodating cavity 110 is used to install components of the integrated valve 10 such as the valve core assembly 200, and is also used for water inflow and outflow. One end of the first water outlet 120 and the second water outlet 130 are connected to the accommodating cavity 110, and the other end is connected to the external pipeline for water inlet or outlet. Among them, the number of the first water outlet 120 and the second water outlet 130 can be set to multiple, or the number of the first water outlet 120 or the second water outlet 130 can be set to one. In this embodiment, the total number of the first water outlet 120 and the second water outlet 130 is set to at least three, so that the function of the integrated valve 10 can be realized. Specifically, the number of the first water outlet 120 is set to one, and the number of the second water outlet 130 is set to at least two.

[0081] The first water outlet 120 and the second water outlet 130 are both connected to the accommodating chamber 110, and the valve core assembly 200 is movably arranged in the accommodating chamber 110 for switching so that the first water outlet 120 and at least one of the second water outlets 130 are connected. In this way, a complete flow path is formed in the integrated valve 10, so that water can flow into any one of the first water outlet 120 and the second water outlet 130 and flow out of the other.

[0082] See also Figure 8 and Figure 9 The integrated valve 10 of the present application has a first mode and a second mode. When the integrated valve 10 is in the first mode, the first water port 120 and any one of the second water ports 130 are independently connected. Water can flow into one of the first water port 120 and out of the other. In this case, the integrated valve 10 functions as a one-way switching valve, switching the water path in the water system using the integrated valve 10. When the integrated valve 10 is in the second mode, the first water outlet 120 is connected to any two adjacent second water outlets 130. If the water flows into the accommodating chamber 110 from the first water outlet 120, the water flowing into the accommodating chamber 110 will flow out from any two adjacent second water outlets 130 respectively. At this time, the integrated valve 10 acts as a water diverter valve, which can divide one water channel in the water channel system using the integrated valve 10 into two water channels; if the water flows into the accommodating chamber 110 from any two adjacent second water outlets 130, the water flowing into the accommodating chamber 110 will flow out from the first water outlet 120. At this time, the integrated valve 10 acts as a mixing valve, which can mix the two water channels in the water channel system using the integrated valve 10 into one water channel.

[0083] The integrated valve 10 of the present invention includes a valve body 100 and a valve core assembly 200; the valve body 100 has a accommodating cavity 110, a first water outlet 120 and at least two second water outlets 130, and the first water outlet 120 and the second water outlet 130 are both connected to the accommodating cavity 110; the valve core assembly 200 is movably arranged in the accommodating cavity 110, for switching to connect the first water outlet 120 and at least one of the second water outlets 130; the integrated valve 10 has a first mode and a second mode, when the integrated valve 10 is in the first mode, the first water outlet 120 and any one of the second water outlets 130 are independently connected; when the integrated valve 10 is in the second mode, the first water outlet 120 and any two adjacent second water outlets 130 are connected. By moving the valve core assembly 200 in the accommodating chamber 110, the integrated valve 10 can be switched between the first mode and the second mode, so that the integrated valve 10 has the corresponding functions of a one-way switching valve, a water diversion valve or a water mixing valve. When the integrated valve 10 is used in a water system, the number of other valve assemblies in the water system can be correspondingly reduced, thereby reducing the cost of the water purification equipment with the above-mentioned water system. At the same time, the volume occupied by one valve is also smaller than the volume occupied by multiple valves, and the overall volume of the water purification equipment can also be reduced. At the same time, the integrated valve 10 also has multiple functions and can be used in a variety of water systems, with strong applicability.

[0084] See also Figures 7 to 10 In one embodiment, the valve core assembly 200 includes a valve core rotor 210 and a valve core stator 220, and the valve core stator 220 is in contact with the valve core rotor 210. One of the valve core rotor 210 and the valve core stator 220 is rotatable relative to the other to switch the integrated valve 10 between the first mode and the second mode.

[0085] Specifically, the valve core rotor 210 and the valve core stator 220 are both made of hard materials, and the hard materials include ceramics. Of course, in other embodiments, the hard materials also include other materials, and there is no specific limitation on this. The valve core rotor 210 and the valve core stator 220 are shaped like a disc, and there is no limitation on the size of the valve core rotor 210 and the valve core stator 220, as long as they can meet the switching function. The valve core stator 220 is sealed against the valve core rotor 210, which can ensure the sealing between the valve core rotor 210 and the valve core stator 220, and prevent water from flowing between the valve core stator 220 and the valve core rotor 210 and out of any outlet. The accommodating chamber 110 is generally cylindrical in shape, facilitating relative rotation between the valve core rotor 210 and the valve core stator 220. This rotation can occur either in the valve core stator 220 relative to the valve core rotor 210 or vice versa, without limitation. This relative rotation allows for switching between the first and second modes. Furthermore, due to the material properties of the materials, a seal between the valve core stator 220 and the valve core rotor 210 is achieved.

[0086] Furthermore, the valve core rotor 210 has a valve core inlet 211, and the valve core stator 220 is provided with multiple valve core outlets 221. The valve core rotor 210 is rotatable relative to the valve core stator 220. The valve core inlet 211 is connected to the first water outlet 120, and the multiple valve core outlets 221 correspond to and are connected to the multiple second water outlets 130 respectively; the rotation of the valve core rotor 210 can make the valve core inlet 211 connected to at least one of the multiple valve core outlets 221.

[0087] Specifically, the valve core inlet 211 can be set as a circular through hole, or as a U-shaped through hole, and the U-shaped through hole is connected to the side of the valve core rotor 210. Setting the shape of the valve core inlet 211 as a U-shaped through hole can increase the water flow area. Similarly, the shape of the valve core outlet 221 can be set as a circular through hole, or as a U-shaped through hole, or can be set as other shapes. In this embodiment, the valve core outlet 221 is set as a circular through hole. The number of the valve core outlets 221 is set to multiple, and the multiple valve core outlets 221 can be arranged at intervals along the circumference of the valve core stator 220. They can be arranged at equal intervals or at non-equal intervals. The line of symmetry is the coincidence line between the diameter of the valve core stator 220 and the diameter of any valve core outlet 221. The multiple valve core outlets 221 can be symmetrically distributed or asymmetrically distributed, and there is no specific limitation on this. The plurality of valve core outlets 221 correspond to and communicate with the plurality of second water outlets 130, respectively. This allows water flowing from the first water outlet 120 into the accommodating chamber 110 to sequentially flow out through the valve core inlet 211, the valve core outlet 221, and the second water outlet 130 corresponding to and communicating with the valve core outlet 221. Rotation of the valve core rotor 210 of this embodiment allows the valve core inlet 211 to communicate with at least one of the plurality of valve core outlets 221, thereby forming a complete water flow path within the integrated valve 10.

[0088] Please continue reading Figures 7 to 10 In one embodiment, the side of the valve core stator 220 that contacts the valve core rotor 210 is provided with a plurality of grooves 223, which are arranged along the circumference of the valve core stator 220. When the valve core rotor 210 contacts the valve core stator 220 and rotates relative to the valve core stator 220, the plurality of grooves 223 on the valve core stator 220 reduce the contact area between the valve core rotor 210 and the valve core stator 220. This reduces the friction between the valve core rotor 210 and the valve core stator 220. Furthermore, when the valve core rotor 210 contacts the valve core stator 220 and rotates relative to the valve core stator 220, the rotation process can clean odors from the valve core stator 220, preventing foreign matter from clogging the integrated valve 10.

[0089] See also Figures 1 to 4In one embodiment, the integrated valve 10 includes a drive device 300 connected to the valve core assembly 200 to drive the valve core assembly 200 to switch the integrated valve 10 between the first mode and the second mode. Specifically, the drive device 300 is connected to the valve core rotor 210 in the valve core assembly 200 to drive the valve core rotor 210 to rotate relative to the valve core stator 220, thereby switching the integrated valve 10 between the first mode and the second mode. Since a plurality of valve core outlets 221 are provided on the valve core stator 220, when the integrated valve 10 is in the first mode, the valve core rotor 210 has a plurality of corresponding rotation positions. When the valve core rotor 210 is in the first position, the valve core inlet 211 is independently connected to a valve core outlet 221. When the valve core rotor 210 is in the second position, the valve core inlet 211 is independently connected to another valve core outlet 221. Each valve core outlet 221 has a corresponding rotation position. The driving device 300 drives the valve core rotor 210 to switch between a plurality of rotation positions, so that the integrated valve 10 acts as a one-way switching valve in the first mode. When the integrated valve 10 is in the second mode, similarly, the valve core rotor 210 has a plurality of corresponding rotation positions. When the valve core rotor 210 is in the first position, the valve core inlet 211 is connected with any two adjacent valve core outlets 221. When the valve core rotor 210 is in the second position, the valve core inlet 211 is connected with any two adjacent valve core outlets 221 again. Each any two adjacent valve core outlets 221 has a corresponding rotation position. The driving device 300 drives the valve core rotor 210 to switch between the plurality of rotation positions, so that the integrated valve 10 acts as a water diversion valve or a water mixing valve in the second mode.

[0090] See also Figure 1 、 Figure 2 、 Figures 11 to 15 In one embodiment, the driving device 300 includes a driving motor 310 and a connecting member 320. The driving motor 310 is installed on the valve body 100, and the connecting member 320 is installed on the accommodating cavity 110. The motor shaft of the driving motor 310 passes through the valve body 100 and is connected to the connecting member 320. The connecting member 320 is connected to the valve core rotor 210.

[0091] Specifically, the valve body 100 includes a valve body 140 and a valve sleeve 150, and the valve body 140 and the valve sleeve 150 are fixedly connected. One side of the valve body 140 has an opening, and the valve sleeve 150 covers the opening to form the accommodating chamber 110. The driving motor 310 is fixedly mounted on the valve sleeve 150, and the valve sleeve 150 is provided with an axial hole 152. The connecting member 320 is arranged in the accommodating chamber 110, and the motor shaft of the driving motor 310 passes through the axial hole 152 and is connected to the connecting member 320. The connecting member 320 is connected to the valve core rotor 210, and the connection method can be a fixed connection, a snap connection, or abutment, and there is no specific limitation on this. Similarly, there is no specific limitation on the shape of the connecting member 320, as long as it can play the role of connecting the valve core rotor 210.

[0092] Of course, in other embodiments, the driving device 300 may also adopt other similar driving structures, as long as it can drive the valve core rotor 210 to rotate relative to the valve core stator 220, and there is no specific limitation on this.

[0093] See also Figures 7 to 10 In one embodiment, the valve core rotor 210 is provided with a first limiting slot 212, and the connecting member 320 is provided with a first clamping portion 321. The first clamping portion 321 is provided in the first limiting slot 212. The valve core rotor 210 is clamped with the connecting member 320. The valve core rotor 210 and the connecting member 320 are connected by clamping. The connection method is simple, easy to assemble, and easy to operate.

[0094] Please continue reading Figures 7 to 10 , Figure 16In one embodiment, the valve core stator 220 is provided with a second position-limiting groove 222. The integrated valve 10 may further include a press sleeve 900, the press sleeve 900 is provided with a second clamping portion 910, and the valve sleeve 150 has a surrounding plate 151. The second clamping portion 910 is provided in the second position-limiting groove 222 and is connected to the surrounding plate 151 through the press sleeve 900 to fix the valve core stator 220 in the accommodating cavity 110. A first sealing member 600 may also be provided between the press sleeve 900 and the valve core stator 220 to ensure the sealing between the press sleeve 900 and the valve core stator 220. Furthermore, the side of the accommodating cavity 110 away from the opening is the bottom wall of the accommodating cavity 110. The press sleeve 900 abuts against the bottom wall. The ends of the plurality of second water outlets 130 that are connected to the accommodating cavity 110 are opened on the bottom wall. A second sealing member 700 may be further provided between the bottom wall and the pressing sleeve 900 to further ensure the sealing between the pressing sleeve 900 and the valve body 100. It should be noted that the pressing sleeve 900, the first sealing member 600, and the second sealing member 700 are all provided with avoidance holes corresponding to the plurality of valve core outlets 221, so that water can flow through the valve core outlets 221.

[0095] See also Figures 6 to 10 In another embodiment, the valve core stator 220 is provided with a second position-limiting groove 222. The side of the accommodating chamber 110 away from the opening serves as the bottom wall of the accommodating chamber 110. One end of the plurality of second water outlets 130 communicating with the accommodating chamber 110 is formed on the bottom wall. The bottom wall is provided with a third engaging portion 111, which is disposed in the second position-limiting groove 222 to secure the position of the valve core stator 220 and prevent the valve core stator 220 from rotating. Furthermore, a third sealing member 800 may be provided between the valve core stator 220 and the bottom wall to further ensure sealing between the valve core stator 220 and the valve body 100.

[0096] See also Figure 13 and Figure 14 In one embodiment, the valve sleeve 150 has a surrounding plate 151, and a water inlet hole 151a is opened on the surrounding plate 151. The water inlet hole 151a is correspondingly connected to the first water outlet 120. The area of ​​the water inlet hole 151a is S1, and the area of ​​the valve core inlet 211 is S2, S1≥S2.

[0097] Specifically, the enclosure 151 is generally annular in shape. When the valve sleeve 150 is fixedly connected to the valve body 140, the enclosure 151 extends into the accommodating chamber 110 and blocks the end of the first water outlet 120 communicating with the accommodating chamber 110. A water inlet hole 151a is defined in the enclosure 151. The location of the water inlet hole 151a corresponds to the location of the end of the first water outlet 120 communicating with the accommodating chamber 110. The area of ​​the water inlet hole 151a is S1, and the area of ​​the valve core inlet 211 is S2, satisfying the condition S1 ≥ S2. With this arrangement, water can flow continuously from the water inlet hole 151a to the valve core inlet 211, ensuring that the water flowing into the valve core inlet 211 is always fully flowed, thereby ensuring the continuity and stability of water outflow.

[0098] Furthermore, the area of ​​the valve core outlet 221 is S3, satisfying S2≥S3. Similarly, the water flowing from the valve core inlet 211 to the valve core outlet 221 can flow continuously, so that the water flowing into the valve core outlet 221 always remains in a full flow state, thereby ensuring the continuity and stability of the water output.

[0099] Furthermore, the cross-sectional area of ​​the second water outlet 130 is S4, satisfying S3 ≥ S4. Similarly, water flowing from the valve core outlet 221 to the second water outlet 130 can flow continuously, ensuring that the water flowing into the second water outlet 130 is always fully flowed, thereby ensuring the continuity and stability of water outflow. It should be emphasized that the cross-sectional area of ​​the first water outlet 120 and the cross-sectional area of ​​the second water outlet 130 can be set to the same area or different areas, and there is no specific limitation on this.

[0100] When the integrated valve 10 satisfies S1≥S2≥S3≥S4, the water flowing from the first water outlet 120 to the accommodating chamber 110 can continuously flow out from the second water outlet 130, ensuring the continuity and stability of the water outlet of the integrated valve 10 and ensuring that the flux of the water system using the integrated valve 10 can be increased.

[0101] See also Figures 1 to 4 In one embodiment, the integrated valve 10 further includes a positioning member 400 and a micro switch 500, wherein the positioning member 400 is sleeved on the motor shaft of the drive motor 310, and the micro switch 500 is installed on the valve sleeve 150; the micro switch 500 is electrically connected to the drive motor 310, and when the positioning member 400 contacts the micro switch 500, the micro switch 500 sends a stop signal to the drive motor 310.

[0102] Specifically, the positioning member 400 is mounted on the motor shaft of the drive motor 310. When the drive motor 310 is operating, the motor shaft rotates, thereby driving the positioning member 400 to rotate synchronously. The valve sleeve 150 is provided with a fixing position for fixing the microswitch 500, which is fixedly mounted on the valve sleeve 150. The microswitch 500 is electrically connected to the drive motor 310. When the drive motor 310 rotates, it drives the positioning member 400 to rotate synchronously. When the positioning member 400 contacts the microswitch 500, the microswitch 500 sends a stop signal to the drive motor 310, causing the drive motor 310 to stop rotating. At this time, the connecting member 320 drives the valve core rotor 210 to rotate to a certain rotation position, so that the valve core inlet 211 is connected to at least one of the multiple valve core outlets 221. The rotation angle of the drive motor 310 can be precisely determined by the number of rotation steps of the microswitch 500 and the drive motor 310. The number of the micro switches 500 can be set to multiple to ensure the accuracy of the rotation position when the driving motor 310 drives the valve core assembly 200 to rotate.

[0103] Of course, in other embodiments, the rotation angle of the driving motor 310 can be positioned by adjusting the number of pulses of the motor, so that the driving motor 310 drives the valve core assembly 200 to switch between the first mode and the second mode.

[0104] See also Figures 17 to 24 The present invention also proposes an integrated valve 10, which includes a valve body 100 and a valve core assembly 200; the valve body 100 has a accommodating cavity 110, a water inlet 120 and multiple water outlets 130, and the water inlet 120 and the water outlet 130 are both connected to the accommodating cavity 110; the valve core assembly 200 includes a valve core rotor 210 and a valve core stator 220, the valve core stator 220 abuts against the valve core rotor 210, the valve core rotor 210 has a valve core inlet 211, and the valve core stator 220 is provided with multiple The valve core outlets 221 are connected to the water inlet 120, and the multiple valve core outlets 221 correspond to and are connected to the multiple water outlets 130 respectively; the rotation of the valve core rotor 210 can make the valve core inlet 211 independently connected to any one of the multiple valve core outlets 221, wherein the multiple valve core outlets 221 include a first water hole 221a and a second water hole 221b, and the aperture of the first water hole 221a is larger than the aperture of the second water hole 221b.

[0105] Specifically, the valve body 100 has a accommodating cavity 110. The shape of the accommodating cavity 110 can be cylindrical, rectangular, or other shapes. The valve body 100 is made of a hard material. As for the type of the hard material, it can be a hard material such as ABS, HIPS, PP, PC, ceramic, or a metal or alloy material, etc., and there is no specific limitation here. The accommodating cavity 110 is used to install components of the integrated valve 10 such as the valve core assembly 200. One end of the water inlet 120 is used for water intake, and the other end is connected to the accommodating cavity 110. One end of the water outlet 130 is connected to the accommodating cavity 110, and the other end is used for water discharge.

[0106] The water inlet 120 and multiple water outlets 130 are all connected to the accommodating cavity 110, and the valve core assembly 200 is movably arranged in the accommodating cavity 110 to switch so that the water inlet 120 and one of the multiple water outlets 130 are independently connected. In this way, a complete flow path is formed in the integrated valve 10, so that water can flow from the water inlet 120 into the accommodating cavity 110 of the integrated valve 10 and flow out from the water outlet 130.

[0107] See also Figure 23 and Figure 24 The valve core assembly 200 includes a valve core rotor 210 and a valve core stator 220. The valve core rotor 210 and the valve core stator 220 are both made of hard materials, including ceramics. Of course, in other embodiments, the hard materials also include other materials, and there is no specific limitation on this. The valve core rotor 210 and the valve core stator 220 are disc-shaped. There is no limitation on the size of the valve core rotor 210 and the valve core stator 220, as long as the valve core can rotate relative to the valve core stator 220 for switching. The valve core stator 220 is in sealing contact with the valve core rotor 210, which can ensure the sealing between the valve core rotor 210 and the valve core stator 220, and prevent water from flowing between the valve core stator 220 and the valve core rotor 210 and flowing out from any port. The accommodating chamber 110 is designed to be roughly cylindrical, so that the valve core rotor 210 can rotate relative to the valve core stator 220. Of course, in other embodiments, the valve core stator 220 can also rotate relative to the valve core rotor 210, and there is no specific limitation on this.

[0108] Furthermore, the valve core rotor 210 has a valve core inlet 211, and the valve core stator 220 is provided with multiple valve core outlets 221. The rotation of the valve core rotor 210 can make the valve core inlet 211 independently connected with any one of the multiple valve core outlets 221. The valve core outlet 221 includes a first water flow hole 221a and a second water flow hole 221b, that is, the valve core rotor 210 can rotate relative to the valve core stator 220, and can make the valve core inlet 211 connected with the first water flow hole 221a, or the valve core inlet 211 connected with the second water flow hole 221b. The diameter of the first water hole 221a is larger than the diameter of the second water hole 221b. This configuration allows the flow rate of water passing through the first and second water holes 221a, 221b to be regulated by limiting the diameters of the first and second water holes 221a, 221b, thereby throttling the flow of water through the integrated valve 10. In this case, the integrated valve 10 functions as a wastewater valve. In this embodiment, the diameter of the first water hole 221a can be set to be equivalent to the diameter of the valve core inlet 211. In this case, when the valve core inlet 211 is connected to the first water hole 221a, the wastewater valve is in the fully open mode (i.e., no throttling is performed on the flow of water through the integrated valve 10); when the valve core inlet 211 is connected to the second water hole 221b, the wastewater valve is in the throttling mode (i.e., throttling is performed on the flow of water through the integrated valve 10). The switching purpose is achieved through the relative rotation between the valve core rotor 210 and the valve core stator 220, and due to the material, the valve core stator 220 and the valve core rotor 210 can be sealed to each other.

[0109] Specifically, the valve core inlet 211 can be set as a circular through hole, or as a U-shaped through hole, and the U-shaped through hole is connected to the side of the valve core rotor 210. Setting the shape of the valve core inlet 211 as a U-shaped through hole can increase the water flow area. Similarly, the shape of the valve core outlet 221 can be set as a circular through hole, or as a U-shaped through hole, or can be set as other shapes. In this embodiment, the valve core outlet 221 is set as a circular through hole. The number of the valve core outlets 221 is set to multiple, and the multiple valve core outlets 221 can be arranged at intervals along the circumference of the valve core stator 220. They can be arranged at equal intervals or at non-equal intervals. The line of symmetry is the coincidence line between the diameter of the valve core stator 220 and the diameter of any valve core outlet 221. The multiple valve core outlets 221 can be symmetrically distributed or asymmetrically distributed, and there is no specific limitation on this. Multiple valve core outlets 221 correspond to and are connected to the multiple water outlets 130 respectively, so that when water flows into the accommodating cavity 110 from the water inlet 120, it can flow out in sequence through the valve core inlet 211, the valve core outlet 221 and the water outlet 130 corresponding to and connected to the valve core outlet 221.

[0110] See also Figure 23 In one embodiment, the plurality of valve core outlets 221 further include a third water hole 221c, the diameter of which is smaller than that of the second water hole 221b. Specifically, the smaller diameter of the third water hole 221c than the second water hole 221b allows the third water hole 221c to provide a stronger throttling effect on flow through the integrated valve 10. The integrated valve 10 can selectively connect the valve core inlet 211 to either the second water hole 221b or the third water hole 221c, as needed, to achieve different throttling effects.

[0111] Please continue reading Figure 23 In one embodiment, the side of the valve core stator 220 that contacts the valve core rotor 210 is provided with a plurality of grooves 223, which are arranged along the circumference of the valve core stator 220. When the valve core rotor 210 contacts the valve core stator 220 and rotates relative to the valve core stator 220, the plurality of grooves 223 on the valve core stator 220 reduce the contact area between the valve core rotor 210 and the valve core stator 220. This reduces the friction between the valve core rotor 210 and the valve core stator 220. Furthermore, when the valve core rotor 210 contacts the valve core stator 220 and rotates relative to the valve core stator 220, the rotation process can clean odors from the valve core stator 220, preventing foreign matter from clogging the integrated valve 10.

[0112] See also Figures 17 to 20 In one embodiment, the integrated valve 10 further includes a driving device 300 connected to the valve core rotor 210 to drive the valve core rotor 210 to rotate so that the valve core inlet 211 is independently connected to any one of the multiple valve core outlets 221. Specifically, the driving device 300 is connected to the valve core rotor 210 in the valve core assembly 200 to drive the valve core rotor 210 to rotate relative to the valve core stator 220, thereby switching the integrated valve 10 between a fully open mode and a throttling mode.

[0113] See also Figures 17 to 20 , Figure 25 and Figure 26 In one embodiment, the driving device 300 includes a driving motor 310 and a connecting member 320. The driving motor 310 is installed on the valve body 100, and the connecting member 320 is installed on the accommodating cavity 110.

[0114] Specifically, the valve body 100 includes a valve body 140 and a valve sleeve 150, and the valve body 140 and the valve sleeve 150 are fixedly connected. One side of the valve body 140 has an opening, and the valve sleeve 150 covers the opening to form the accommodating chamber 110. The driving motor 310 is fixedly mounted on the valve sleeve 150, and the valve sleeve 150 is provided with an axial hole 151. The connecting member 320 is arranged in the accommodating chamber 110, and the motor shaft of the driving motor 310 passes through the axial hole 151 and is connected to the connecting member 320. The connecting member 320 is connected to the valve core rotor 210, and the connection method can be a fixed connection, a snap connection, or abutment, and there is no specific limitation on this. Similarly, there is no specific limitation on the shape of the connecting member 320, as long as it can play the role of connecting the valve core rotor 210.

[0115] Of course, in other embodiments, the driving device 300 may also adopt other similar driving structures, as long as it can drive the valve core rotor 210 to rotate relative to the valve core stator 220, and there is no specific limitation on this.

[0116] See also Figures 23 to 26 In one embodiment, the valve core rotor 210 is provided with a first limiting slot 212, and the connecting member 320 is provided with a first clamping portion 321. The first clamping portion 321 is provided in the first limiting slot 212. The valve core rotor 210 is clamped with the connecting member 320. The valve core rotor 210 and the connecting member 320 are connected by clamping. The connection method is simple, easy to assemble, and easy to operate.

[0117] See also Figures 23 to 26In one embodiment, the valve core stator 220 is provided with a second limit slot 222. The integrated valve 10 may further include a press sleeve 900. The press sleeve 900 is provided with a second clamping portion 910. The valve sleeve 150 has a surrounding plate. The second clamping portion 910 is provided in the second limit slot 222 and is connected to the surrounding plate through the press sleeve 900 to fix the valve core stator 220 in the accommodating cavity 110. A first sealing member 600 may be further provided between the press sleeve 900 and the valve core stator 220 to ensure the sealing between the press sleeve 900 and the valve core stator 220. Furthermore, the side of the accommodating cavity 110 away from the opening is the bottom wall of the accommodating cavity 110. The press sleeve 900 abuts against the bottom wall. One end of the plurality of second water outlets communicating with the accommodating cavity 110 is opened on the bottom wall. A second sealing member 700 may be further provided between the bottom wall and the pressing sleeve 900 to further ensure the sealing between the pressing sleeve 900 and the valve body 100. It should be noted that the pressing sleeve 900, the first sealing member 600, and the second sealing member 700 are all provided with avoidance holes corresponding to the plurality of valve core outlets 221, so that water can flow through the valve core outlets 221.

[0118] See also Figures 22 to 30 In another embodiment, the valve core stator 220 is provided with a second position-limiting groove 222. The side of the accommodating chamber 110 away from the opening serves as the bottom wall of the accommodating chamber 110. Multiple second water outlets are provided on the bottom wall at one end, communicating with the accommodating chamber 110. A third engaging portion 111 is provided on the bottom wall. The third engaging portion 111 is disposed in the second position-limiting groove 222 to secure the position of the valve core stator 220 and prevent it from rotating. Furthermore, a third sealing member 800 may be provided between the valve core stator 220 and the bottom wall to further ensure sealing between the valve core stator 220 and the valve body 100.

[0119] See also Figures 17 to 20 In one embodiment, the integrated valve 10 further includes a positioning member 400 and a micro switch 500, wherein the positioning member 400 is sleeved on the motor shaft of the drive motor 310, and the micro switch 500 is installed on the valve sleeve 150; the micro switch 500 is electrically connected to the drive motor 310, and when the positioning member 400 contacts the micro switch 500, the micro switch 500 sends a stop signal to the drive motor 310.

[0120] Specifically, the positioning member 400 is mounted on the motor shaft of the drive motor 310.
