[0058] As Figures 1 to 9As shown, according to the embodiment of the present application, a double-core valve 100 is provided, which comprises a valve seat 10, a first valve core 20 and a second valve core 30, specifically, the first valve core 20 is arranged in the valve seat 10, the first valve core 20 has a first open position and a first closed position, at least part of the second valve core 30 is arranged in the interior of the first valve core 20, and the second valve core 30 has a second open position and a second closed position.

[0059] When the first valve core 20 is in the first open position (as shown in FIG. 1A), a first channel is formed between the first valve core 20 and the valve seat 10, and at this time, the first valve core 20 is in the first closed position (as shown in FIG. 1B), and the first channel is in a closed state. Figure 6 When the first valve core 20 is in the first open position (as shown in FIG. 1A), a first channel is formed between the first valve core 20 and the valve seat 10, and at this time, the first valve core 20 is in the first closed position (as shown in FIG. 1B), and the first channel is in a closed state. Figure 7 When the first valve core 20 is in the first open position (as shown in FIG. 1A), a first channel is formed between the first valve core 20 and the valve seat 10, and at this time, the first valve core 20 is in the first closed position (as shown in FIG. 1B), and the first channel is in a closed state.

[0060] When the second valve core 30 is in the second open position (as shown in FIG. 2A), a second channel is formed between the second valve core 30 and the first valve core 20, and at this time, the second valve core 30 is in the second closed position (as shown in FIG. 2B), and the second channel is in a closed state. Figure 6 When the second valve core 30 is in the second open position (as shown in FIG. 2A), a second channel is formed between the second valve core 30 and the first valve core 20, and at this time, the second valve core 30 is in the second closed position (as shown in FIG. 2B), and the second channel is in a closed state. Figure 7 When the second valve core 30 is in the second open position (as shown in FIG. 2A), a second channel is formed between the second valve core 30 and the first valve core 20, and at this time, the second valve core 30 is in the second closed position (as shown in FIG. 2B), and the second channel is in a closed state.

[0061] According to the double-core valve 100 of the present application, the first channel of the double-core valve 100 can be opened and closed by the cooperation of the valve seat 10 and the first valve core 20, and the second channel of the double-core valve 100 can be opened and closed by the cooperation of the first valve core 20 and the second valve core 30, so that the first channel and the second channel can be switched between the open state and the closed state, respectively, and the first channel and the second channel are arranged independently, which can ensure that the first channel and the second channel are isolated from each other to prevent the first channel and the second channel from being communicated. The double-core valve 100 integrates the second channel for realizing liquid inlet and the first channel for realizing liquid outlet, and can realize the opening and closing of the two channels at the same time, compared with the existing water inlet valve and water outlet valve, the structure is simplified, and the installation space of the water inlet valve and the water outlet valve is saved.

[0062] In some embodiments of the present application, the first valve core 20 is arranged in the valve seat 10 in a movable manner relative to the valve seat 10, and by moving the position of the first valve core 20, the relative position of the first valve core 20 and the valve seat 10 is changed, i.e. the first valve core 20 is switched between the first open position and the first closed position, so as to change the opening and closing state of the first channel between the first valve core 20 and the valve seat 10. Specifically, when the first valve core 20 is moved to the first open position, the first channel formed between the first valve body and the valve seat 10 is opened to allow fluid to pass through, and when the first valve core 20 is moved to the first closed position, the first channel is closed to hinder the flow of fluid.

[0063] Further, the length direction of the first channel is parallel to the moving direction of the first valve core 20, and the first channel is arranged along the circumference of the first valve core 20, so as to ensure that the first valve core 20 and the valve seat 10 are subjected to uniform liquid pressure, and meanwhile, the first valve core 20 and the valve seat 10 are subjected to uniform force when they abut against each other, so as to improve the service life of the first valve core 20 and the valve seat 10. The first channel can also be arranged on one side of the first valve core 20, or on opposite sides of the first valve core 20, that is, the first valve core 20 forms the first channel with the valve seat 10 only on one side or on both sides, and the other side of the first valve core 20 is in sealed contact with the valve seat 10.

[0064] In some other embodiments of the present application, the first valve core 20 can also be arranged in the valve seat 10 in a rotating manner relative to the valve seat 10. When the first valve core 20 is rotated to the first open position, the first channel formed between the first valve core 20 and the valve seat 10 is opened, so that the fluid can pass through. When the first valve core 20 is rotated to the first closed position, the first channel is closed, so as to hinder the fluid flow.

[0065] As shown in Figure 2 , Figures 4 to 7 , the valve seat 10 comprises a valve seat body 11, and the first valve core 20 is arranged in the valve seat body 11. The first channel can be opened or closed by cooperation between the first valve core 20 and the valve seat body 11. Specifically, the valve seat body 11 is a shell structure, the inside of the shell structure forms a first accommodating cavity 101, the first valve core 20 is arranged in the first accommodating cavity 101, and the two ends of the shell structure are further provided with a first liquid inlet 102 and a first liquid outlet 103.

[0066] When the first valve core 20 is moved away from the first liquid outlet 103, a gap is formed between the first valve core 20 and the first liquid outlet 103, so that the first accommodating cavity 101, the first liquid outlet 103 and the first liquid inlet 102 are communicated to form a first channel through which the liquid can flow. At this time, the first valve core 20 is in the first open position.

[0067] When the first valve core 20 is moved towards the first liquid outlet 103, the first valve core 20 blocks the first liquid outlet 103, and the first accommodating cavity 101, the first liquid outlet 103 and the first liquid inlet 102 are no longer communicated. At this time, the first valve core 20 is in the first closed position.

[0068] Specifically, the first valve core 20 is slidably connected to the valve seat body 11 of the shell structure. The first valve core 20 is moved along the inner wall of the valve seat body 11 by external force or liquid flow pressure. A first elastic member 125 is arranged between the first valve core 20 and the valve seat body 11. After the external force is released or the liquid flow pressure is released, the first valve core 20 is reset (i.e., the first valve core 20 moves to the first closed position) by the first elastic member 125.

[0069] In order to increase the first passage flow space of the valve seat body 11, the first valve core 20 can also be arranged in the first accommodating cavity 101 of the valve seat body 11 through other components. Specifically, the valve seat 10 comprises a first support 12 for supporting the first valve core 20, the first support 12 is connected to the inner wall of the valve seat body 11, and the first support 12 is accommodated in the first accommodating cavity 101, the first valve core 20 is connected to the first support 12 in a sliding manner, and a first elastic member 125 is arranged between the first valve core 20 and the first support 12.

[0070] The first valve core 20 is moved by external force or pressure of liquid flow to move the first valve core 20 along the first support 12 in a direction away from the first liquid outlet 103, so that the first passage is communicated; after the external force is released or the liquid flow pressure is released, the first valve core 20 is reset by the elastic force of the first elastic member 125, so that the first valve core 20 blocks the first liquid outlet 103.

[0071] As shown in Figure 4 , Figure 8 , Figure 9 , the first support 12 comprises a first support body 121, a first support arm 122 and a first connecting part 123. Specifically, the first support body 121 is supported on the inner wall of the valve seat body 11, and can be installed on the inner wall of the valve seat body 11 in an interference fit, or a support connecting member can be arranged to support on the inner wall of the valve seat body 11. The first end of the first support arm 122 is connected with the first support body 121, the second end of the first support arm 122 is connected with the first connecting part 123, and the first valve core 20 is slidingly connected with the first connecting part 123. The second end of the first support arm 122 extends towards the center of the first accommodating cavity 101, so that the first valve core 20 can be arranged at the center position of the first accommodating cavity 101, and the space size of the first passage between the first valve core 20 and the valve seat body 11 along the circumference of the first valve core 20 is more uniform, so that the first valve core 20 is not subjected to uneven liquid pressure.

[0072] Specifically, the number of the first support arms 122 is at least one, and one first support arm 122 can support the connection of the first connecting part 123 and the first valve core 20. When the number of the first support arms 122 is two or more, the two or more first support arms 122 are uniformly arranged along the circumference of the valve seat body 11, so as to uniformly bear the force on the first connecting part 123 and the first support body 121, and to uniformly distribute the flowing liquid in the first passage, thereby improving the service life of the first support 12. Specifically, the number of the first support arms 122 in the present application is four, and the four support arms can further improve the firmness of the support member.

The second seal 127 is a ring-shaped sealing structure, and when the first valve core 20 moves to the first closed position, the first valve core 20 abuts against the inner ring of the ring-shaped sealing structure and forms a circumferential seal to prevent liquid from being discharged from the first liquid outlet 103.

When the first valve core 20 is in the first closed position, the first valve core 20 abuts against the sealing lip 1271 and forms a circumferential seal.

[0084] In some embodiments of the present application, the second valve core 30 is arranged in a movable manner relative to the first valve core 20, and the position of the first valve body is moved by an external force or liquid pressure, so that the relative position of the second valve core 30 and the first valve core 20 changes, i.e., the second valve core 30 is converted between the second open position and the second closed position, thereby changing the state of the second passage between the first valve core 20 and the first valve core 20. Specifically, when the second valve core 30 moves to the second open position, the second passage formed between the second valve core 30 and the first valve core 20 is opened to facilitate fluid passing, and when the second valve core 30 moves to the second closed position, the second passage is closed to hinder fluid flow.

[0085] Further, the length direction of the second passage is parallel to the moving direction of the second valve core 30, and the second passage is arranged along the circumference of the second valve core 30, so as to ensure that the second valve core 30 and the first valve core 20 are subjected to uniform liquid pressure, and when the second valve core 30 and the first valve core 20 abut, both are subjected to uniform force, so as to improve the service life of the second valve core 30 and the first valve core 20.

[0088] When the second valve core 30 is moved by an external force or liquid pressure in a direction away from the second liquid outlet 203, the second accommodating cavity 201, the second liquid inlet 202 and the second liquid outlet 203 are communicated and jointly form a second channel through which liquid can flow, at this time, the second valve core 30 is in the second open position; when the second valve core 30 is moved in a direction close to the second liquid inlet 202 to block the second liquid inlet 202, at this time, the second valve core 30 is in the second closed position.

[0089] Specifically, the second valve core 30 is slidably connected to the inside of the first valve core body 21, and when the second valve core 30 is moved by an external force or liquid flow pressure, the second valve core 30 moves along the inner wall of the first valve core body 21, and a second elastic member 221 is arranged between the second valve core 30 and the first valve core body 21, so that after the external force is released or the liquid flow pressure is released, the second valve core 30 is reset (i.e., the second valve core 30 moves to the second closed position) by the second elastic member 221.

[0090] In order to increase the flow space of the second channel of the first valve core body 21, the second valve core 30 can also be arranged in the second accommodating cavity 201 of the first valve core body 21 by other components, specifically, the first valve core 20 comprises a second support member 22 for supporting the second valve core 30, the second support member 22 is supported on the inner wall of the first valve core body 21 and accommodated in the second accommodating cavity 201, and the second valve core 30 is slidably connected to the second support member 22, and a space is formed between the second valve core 30 and the first valve core body 21 to facilitate liquid flow.

[0092] In some embodiments of the present application, the second support member 22 comprises a second support arm 222 and a second connecting portion 223, specifically, the second support arm 222 is detachably connected to the first valve core body 21, the first end of the second support arm 222 is connected to the second connecting portion 223, and the second valve core 30 is slidably connected to the second connecting portion 223, wherein the first end of the second support portion 1212 extends towards the center of the second accommodating cavity 201 to form a space, so that the second valve core 30 can be arranged at the center of the second accommodating cavity 201, and the size of the space between the second valve core 30 and the first valve core body 21 along the circumference of the second valve core 30 is more uniform.

[0093] Specifically, the number of the second support arms 222 is at least one, one second support arm 222 can support the second connecting part 223 to connect with the second valve core 30, when the number of the second support arms 222 is two or more, the two or more second support arms 222 are uniformly arranged along the circumference of the first valve core body 21, to ensure that the second connecting part 223 is uniformly stressed, and at the same time, the flow of liquid in the second channel is more evenly distributed, thereby improving the service life of the second support 22. Specifically, the number of the second support arms 222 in the present application is four, and the four second support arms 222 can further improve the firmness of the support.

[0094] Further, as shown in Figure 8 The second support arm 222 is provided with a second clamping part 2221, and the inner wall of the first valve core body 21 is provided with a second clamping part 212 matched with the second clamping part 2221, so that the second support arm 222 is detachably connected to the first valve core body 21 through the cooperation of the second clamping part 2221 and the second clamping part 212. Further, the second support arm 222 is also formed with a relief groove 2222, which is arranged near the second clamping part 2221, so as to facilitate the disassembly of the second clamping part 2221 and the second clamping part 212. Among them, the second clamping part 2221 is a protruding structure, and correspondingly, the second clamping part 212 is a groove structure, in addition, the second support arm 222 and the first valve core body 21 can also be detachably connected through the threaded connection.

[0095] In order to facilitate the reset of the second valve core 30, a second elastic member 221 is arranged between the second connecting part 223 and the second valve core 30 along the moving direction of the second valve core 30.

[0096] Specifically, the second connecting part 223 is formed by the extension of the first end of the second support arm 222 along the moving direction of the second valve core 30 towards the second liquid outlet 203, part of the second valve core 30 is arranged in the second connecting part 223, the first end of the second valve core 30 near the second liquid outlet 203 is located outside the second connecting part 223, and the first end of the second valve core 30 is provided with a second limiting part 3111, the second elastic member 221 is sleeved on the outer wall of the second connecting part 223, one end of the second elastic member 221 abuts against the second limiting part 3111, and the other end of the second elastic member 221 abuts against the connection between the second connecting part 223 and the second support arm 222.

[0097] When the second spool 30 is pushed to move by external force or liquid pressure, the second spool 30 moves along the inner wall of the second connecting part 223 towards the direction of the second liquid inlet 202, at the same time, the second elastic member 221 is compressed, when the external force or liquid pressure is released, the second elastic member 221 is converted from the compressed state to the stretched state, under the elastic force of the second elastic member 221, the second spool 30 moves along the inside of the second connecting part 223 towards the direction of the second liquid outlet 203. In the present application, the first elastic member 125 and the second elastic member 221 are both springs, and can also be other elastic objects.

[0098] Specifically, the second connecting part 223 can be a closed ring structure, the outer wall of the ring structure forms a ring-shaped second limiting part 3111; the second connecting part 223 can also be an open ring structure, the outer wall of the open ring structure forms a second limiting part 3111 in the circumferential direction; the second connecting part 223 can also be at least two connecting blocks, the at least two connecting blocks are uniformly arranged along the circumference of the second spool 30, and the side of the connecting block away from the second spool 30 is provided with a second limiting part 3111. Since the closed ring structure can ensure that the second spool 30 is uniformly stressed, at the same time, the second connecting part 223 of the closed ring structure can play a role in connecting multiple second support arms 222, so as to improve the firmness of the second support member 22, therefore, the second connecting part 223 of the closed ring structure is preferred in the present application.

[0099] Further, the second support arm 222 can be detachably connected with the first spool body 21 through the second end, or a structure detachably connected with the first spool body 21 can be arranged between the first end and the second end. In order to further improve the overall firmness of the second support member 22, the second end of the second support arm 222 is connected through the second support body 224.

[0100] Specifically, the second support member 22 further comprises a second support body 224, the second support body 224 is arranged in the second accommodating cavity 201 of the first spool body 21 and close to the circumferential inner wall of the first spool body 21, the second support body 224 is connected with the second end of the second support arm 222 away from the second connecting part 223, and the second support body 224 is used to support the second support arm 222, at the same time, the second support body 224 is connected with the second end of each of the four second support arms 222, so as to improve the overall firmness of the second support member 22.

[0101] Among them, the second end of the second support arm 222 extends to the position of the second clamping part 2221 along the inner wall of the second accommodating cavity 201 towards the second liquid inlet 202, and then extends to the inside of the second accommodating cavity 201 along the radial direction of the second accommodating cavity 201.

[0102] In some embodiments of the present application, the second valve core 30 can directly block the second liquid inlet 202 of the first valve core body 21, at this time, the position of the first valve core body 21 close to the second liquid inlet 202 needs to form a structure matched with the shape of the second valve core 30, which makes the internal shape of the first valve core body 21 complex.

[0103] In order to reduce the processing difficulty of the first valve core body 21, the first valve core body 21 of the present application is provided with a blocking structure inside. Specifically, the first valve core 20 further comprises a blocking piece 23 arranged in the first valve core body 21, the second containing cavity 201 inside the first valve core body 21 is formed with a step 204 along the moving direction of the second valve core 30, the cross-sectional area of the second liquid inlet 202 of the second containing cavity 201 is smaller than that of the second liquid outlet 203 of the second containing cavity 201, and the step 204 is arranged close to one end of the second liquid inlet 202 of the second containing cavity 201 to support and limit the blocking piece 23.

[0104] Specifically, the blocking piece 23 is connected to the first valve core body 21 through the third sealing piece 24, the third sealing piece 24 is elastically supported between the blocking piece 23 and the first valve core body 21, the third sealing piece 24 plays the role of elastic support, at the same time, the third sealing piece 24 also seals the gap between the blocking piece 23 and the first valve core body 21.

[0105] Corresponding to the second valve core 30, the blocking piece 23 comprises a blocking body 231 and a first blocking part 232, the blocking body 231 is connected with the first blocking piece 232, the third sealing piece 24 is supported between the blocking body 231 and the first valve core body 21, the blocking body 231 is in a ring structure, and the third sealing piece 24 is sleeved on the circumferential outer wall of the blocking body 231 to ensure the sealing between the blocking piece 23 and the valve seat body 11.

[0106] In order to improve the sealing between the blocking piece 23 and the second valve core 30, the first blocking part 232 is matched with the end of the second valve core 30 close to the first liquid inlet 102, the first blocking part 232 is in a ring structure, and the diameter of the first blocking part 232 gradually increases from the second liquid inlet 202 to the second liquid outlet 203, so that the second valve core 30 can smoothly enter the inner ring of the first blocking part 232.

[0107] In some embodiments of the present application, the second valve core 30 is provided with a fourth sealing member 32 at one end close to the blocking member 23, and the second valve core 30 is sealingly connected with the first blocking part 232 of the blocking member 23 through the fourth sealing member 32 when the second valve core 30 is in the second closed position, so as to block the fluid from passing through, thereby closing the second channel. In addition, the first blocking part 232 can also be made of soft material which can play a sealing role, and in this case, the one end of the second valve core 30 close to the blocking member 23 can be sealingly connected with the first blocking part 232 of the soft material through the fourth sealing member 32, or the hard material part of the second valve core 30 can be directly sealingly connected with the first blocking part 232 of the soft material. In the present application, the first sealing member 126, the third sealing member 24 and the fourth sealing member 32 are all sealing rings.

[0108] Specifically, the second valve core 30 comprises a second valve core body 31, at least part of the second valve core body 31 is arranged through the second connecting part 223, so as to ensure that the second valve core body 31 can move along the second connecting part 223, and the outer wall of one end of the second valve core body 31 close to the second liquid inlet 202 is provided with the fourth sealing member 32, and the side of the valve core body away from the second liquid inlet 202 is provided with a second limiting part 3111.

[0109] Further, the second valve core body 31 comprises a second blocking part 311 and a third connecting part 312, wherein at least part of the third connecting part 312 is arranged through the second connecting part 223 and can move relative to the second connecting part 223, the second blocking part 311 is connected to one end of the third connecting part 312 close to the second liquid inlet 202, one end of the second blocking part 311 away from the second liquid inlet 202 is provided with the second limiting part 3111, the second limiting part 3111 is formed as a groove structure along the circumference of the third connecting part 312, specifically, it can be an annular groove or a plurality of grooves forming an annular structure, when the second valve core 30 is in the second open position, the bottom of the groove structure abuts against the second connecting part 223, and at the same time, the second elastic member 221 is in a compressed state between the connecting part (the connecting part of the second supporting arm 222 and the second connecting part 223) and the second limiting part 3111, when the second valve core 30 is in the second closed position, a certain distance is formed between the bottom of the groove structure and the second connecting part 223, and at the same time, the second elastic member 221 is in an extended state.

[0110] The second blocking part 311 gradually decreases in cross-sectional area (cross-sectional area perpendicular to the moving direction of the second valve core 30) from the middle position to both ends along the moving direction of the second valve core 30, so as to ensure that the end of the second blocking part 311 close to the second liquid inlet 202 can smoothly move into the space formed by the first blocking part 232, and the end of the second blocking part 311 away from the second liquid inlet 202 can smoothly move into the space formed by the second supporting arm 222. The fourth sealing member 32 is arranged in the circumferential direction of the end of the second blocking part 311 close to the second liquid inlet 202. Further, in order to facilitate the disassembly of the fourth sealing member 32, the end of the second blocking part 311 away from the third connecting part 312 is provided with a fixing part 33. Part of the fixing part 33 extends into the interior of the second blocking part 311, and the remaining fixing part 33 is in a plate or sheet structure. The remaining fixing part 33 and the outer side of the second blocking part 311 jointly form a groove structure for accommodating the fourth sealing member 32. The fourth sealing member 32 is more convenient to disassemble through the detachable connection between the fixing part 33 and the second blocking part 311.

[0111] In some embodiments of the present application, the valve seat 10 further comprises a filter cover 13 arranged at the end of the valve seat body 11 close to the first liquid inlet 102. The filter cover 13 is provided with a liquid outlet hole 131 and a filter hole 132. When the first valve core 20 is driven to move to the first open position by external force or liquid pressure, the first channel is connected through the filter hole 132. The liquid on the side of the filter cover 13 away from the first channel enters the first channel through the filter hole 132 and is discharged from the first liquid outlet 103 of the first channel of the double-core valve 100. The filter hole 132 can prevent impurities in the liquid on the side of the filter cover 13 away from the first channel from entering the first channel, thereby preventing the first channel of the double-core valve 100 from being blocked. In addition, the liquid in the first channel can also flow to the side of the filter cover 13 away from the first channel. When the second valve core 30 is driven to move to the second open position by external force or liquid pressure, the second channel is connected through the liquid outlet hole 131. The liquid in the second channel can enter the side of the filter cover 13 away from the second channel through the liquid outlet hole 131.

[0112] Specifically, the double-core valve 100 of the present application is used to be arranged in a clothes treatment device. One side of the double-core valve 100 provided with the filter cover 13 is arranged in a cavity capable of accommodating liquid, and the other side of the double-core valve 100 is used to be connected to a water inlet and outlet pipeline. The first channel of the double-core valve 100 is a liquid outlet channel for discharging liquid in the cavity of the device on the side of the filter cover 13 away from the first channel. The second channel of the double-core valve 100 is a liquid inlet channel for allowing external liquid to enter the cavity of the device on the side of the filter cover 13 away from the second channel.

[0113] When water needs to be supplied to the garment processing equipment, external liquid enters the second receiving cavity 201 through the second inlet 202. The liquid pressure moves the second valve core 30 in a direction away from the second inlet 202, thereby opening the second channel (e.g., Figure 6 As shown), the liquid flows within the second channel to the position of the second outlet 203, and is introduced into the cavity of the garment processing device through the outlet hole 131 of the filter cover 13 (as shown). Figure 5 (As shown by the solid black arrow), thus enabling water supply to the garment processing equipment. The second channel is only open when the second valve core 30 moves away from the second liquid inlet 202. When liquid is no longer supplied through the second channel, and liquid in the chamber of the garment processing equipment enters the second channel through the liquid outlet 131 of the filter cover 13, the pressure of the liquid drives the second valve core 30 to move towards the second liquid inlet 202 until the second valve core 30 moves to the second closed position to prevent liquid in the chamber from entering the water supply channel through the second channel and contaminating the water supply source.

[0114] When drainage is required from the garment processing equipment, external force or liquid pressure pushes the first valve core 20, causing it to move away from the first outlet 103 to open the first channel (e.g., Figure 6 As shown), the liquid inside the chamber of the garment processing equipment enters the first channel through the filter holes 132 of the filter cover 13, and is discharged from the first outlet 103 of the first channel through the dual-core valve 100 (as shown). Figure 5 (As shown by the black wireframe arrow), thereby draining the liquid from the cavity.

[0115] In other embodiments of this application, the first channel and the second channel can be two drainage channels spaced apart or two liquid inlet channels spaced apart. This application does not limit the specific functions of the first channel and the second channel. Those skilled in the art can connect different drainage pipes and water inlet pipes according to the actual situation.

[0116] Further, the liquid outlet hole 131 is arranged at the center of the filter cover 13, the filter holes 132 are arranged along the circumference of the liquid outlet hole 131, the liquid second channel introduces liquid to the liquid outlet hole 131 at the center of the filter cover 13, and the liquid needs to be introduced into the first channel through the filter holes 132 arranged along the circumference of the filter cover 13. Since the liquid inlet pressure is relatively large compared with the liquid outlet pressure, the liquid outlet hole is arranged at the center of the filter cover 13, and correspondingly, the second channel is arranged at the middle position of the double spool valve 100, the liquid inlet pipe is connected to the second spool 30 to make the liquid inlet directly pass through the second channel and the liquid outlet hole into the cavity of the clothes treatment equipment, so that the impact of the liquid inlet pressure on the first spool 20 can be reduced; the filter holes 132 are arranged in the circumferential direction of the filter cover 13, and correspondingly, the first channel is arranged at the side of the first spool 20, the liquid outlet is introduced into the first channel arranged along the circumference of the first spool 20, which will cause a certain impact on the first spool 20, but since the liquid outlet pressure is much smaller than the liquid inlet pressure, arranging the liquid outlet hole 131 and the second channel near the axis of the double spool valve 100 and arranging the filter holes 132 and the first channel at the side of the second channel can minimize the impact on the first spool 20. In addition, when the first spool 20 has high strength, the filter holes 132 can also be arranged near the axis of the double spool valve 100, the liquid outlet hole 131 can be arranged in the circumferential direction of the filter holes 132, or the liquid outlet hole 131 and the filter holes 132 can be arranged at other positions according to actual needs.

[0117] Specifically, the number of filter holes 132 is at least two, the two filter holes 132 can be groove structures arranged along the circumference of the filter cover 13, the number of filter holes 132 can also be greater than two, the shape of the filter holes 132 can also be a circular hole structure, and the filter holes 132 can also be other shapes. Those skilled in the art can set the shape and size (such as diameter, side length) of the filter holes 132 according to the volume of the filter cover 13.
