Description

Technical Field

[0001] This application relates to the field of filtration technology, and more specifically, to a filter and an integrated component. Background Technology

[0002] In the fluid transportation process of pipelines, fluid circulation is often involved. During this circulation, impurities easily accumulate in the fluid, affecting its normal operation. Taking the fluid circulation within the flow channel plate of a heat pump unit as an example, impurities are easily generated as the fluid circulates within the flow channel plate. These impurities can cause malfunctions or damage to components such as the condenser and liquid receiver when they flow through them. Therefore, it is necessary to filter the fluid within the flow channel plate. However, the filter needs to be frequently cleaned of the filter residue to reduce the risk of filter clogging. Removing the filter residue involves disassembling and reassembling the filter, which is a cumbersome operation. Utility Model Content

[0003] This application provides a filter and an integrated component that can reduce the difficulty of disassembling and assembling the filter.

[0004] This application provides a filter, including a valve assembly, a filter assembly, and a snap-fit ​​component. The valve assembly includes a valve body and a valve core. The valve body includes a valve cavity and an inlet channel. The valve core is disposed in the valve cavity and has a first position and a second position. The filter assembly includes a filter cover and a filter screen. The filter screen is disposed within the filter cover and divides the internal space of the filter cover into an inlet chamber and an outlet chamber. The inlet chamber and the outlet chamber are connected through the filter holes of the filter screen. When the valve core is in the first position, the inlet channel is connected to the inlet chamber; when the valve core is in the second position, the inlet channel is disconnected from the inlet chamber. The snap-fit ​​component is fastened to the valve body and the filter cover to secure them.

[0005] In this application, by configuring a valve assembly and a filter assembly, the valve assembly can manage the flow between the inlet channel of the valve body and the inlet chamber of the filter cover. This allows for restriction of fluid entry into the inlet chamber when the valve core is in the second position, reducing the risk of leakage at the valve body's inlet channel when cleaning filter residue from the filter assembly. The use of snap-fit ​​fasteners to the valve body and filter cover reduces the difficulty of disassembling and assembling the valve body and filter cover, and also reduces the difficulty of cleaning filter residue.

Detailed Implementation

[0009] To make this application clearer, specific embodiments are described below with reference to the accompanying drawings: Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of an integrated component 100 provided in some embodiments of this application. Embodiments of this application provide an integrated component 100, which may include a filter 10 and a flow channel plate 20. The flow channel plate 20 has a first flow channel 202 and a second flow channel 203. The filter 10 is mounted on the flow channel plate 20 to control the opening and closing of the first flow channel 202 and the second flow channel 203.

[0010] The flow channel plate 20 can guide, distribute, and manage the flow of fluid within it. The filter 10 is connected to the flow channel plate 20 to control the opening and closing of the flow channels within the flow channel plate 20. The filter 10 and flow channel plate 20 can be fixedly connected; for example, the filter 10 and flow channel plate 20 can be welded together. Alternatively, the filter 10 and flow channel plate 20 can be detachably connected; for example, the filter 10 and flow channel plate 20 can be connected by fasteners, such as bolts; or, for example, the filter 10 and flow channel plate 20 can be snap-fitted together.

[0011] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 2This is a schematic diagram of the structure of the filter 10 provided in some embodiments of this application; Figure 3 for Figure 2 AA cross-sectional view (valve core 12 is in the first position); Figure 4 A schematic diagram of the structure of a filter 10 provided in some embodiments of this application (valve core 12 is located in the second position); Figure 5 Exploded view of filter 10 provided in some embodiments of this application; Figure 6 This is a schematic diagram illustrating the assembly of the filter screen 22 and filter cover 21 provided in some embodiments of this application. Embodiments of this application provide a filter 10, including a valve assembly 1, a filter assembly 2, and a snap-fit ​​component 3. The valve assembly 1 includes a valve body 11 and a valve core 12. The valve body 11 includes a valve cavity 111 and an inlet channel 112. The valve core 12 is disposed in the valve cavity 111 and has a first position and a second position. The filter assembly 2 includes a filter cover 21 and a filter screen 22. The filter screen 22 is disposed within the filter cover 21 and divides the internal space of the filter cover 21 into an inlet chamber 211 and an outlet chamber 212. The inlet chamber 211 and the outlet chamber 212 are connected through the filter holes of the filter screen 22. When the valve core 12 is in the first position, the inlet channel 112 is connected to the inlet chamber 211. When the valve core 12 is in the second position, the inlet channel 112 is disconnected from the inlet chamber 211. The fastener 3 is fastened to the valve body 11 and the filter cover 21 to fix the valve body 11 and the filter cover 21.

[0012] Valve assembly 1 can be a gate valve, butterfly valve, ball valve, etc. For example, if valve assembly 1 is a gate valve, the valve core 12 is a gate, and the valve core 12 moves within the valve chamber 111. The valve core 12 can reach a first position connecting the inlet channel 112 and the inlet chamber 211, and a second position blocking the valve chamber 111 to disconnect the inlet channel 112 and the inlet chamber 211. Alternatively, if valve assembly 1 is a ball valve, the valve core 12 is a ball, and the valve core 12 rotates within the valve chamber 111. The valve core 12 can rotate to a first position connecting the inlet channel 112 and the inlet chamber 211, and a second position disconnecting the inlet channel 112 and the inlet chamber 211. In embodiments where valve assembly 1 is a ball valve, the valve core 12 may have a notch. When the valve core 12 is in the first position, the notch connects the inlet channel 112 and the inlet chamber 211. When the valve core 12 is in the second position, the notch is offset from at least one of the inlet channel 112 and the inlet chamber 211 to disconnect the inlet channel 112 and the inlet chamber 211. Alternatively, the valve core 12 may have a through hole. When the valve core 12 is in the first position, the through hole connects the inlet channel 112 and the inlet chamber 211. When the valve core 12 is in the second position, the through hole is offset from at least one of the inlet channel 112 and the inlet chamber 211 to disconnect the inlet channel 112 and the inlet chamber 211.

[0013] The valve body 11 may also include a liquid outlet channel 113, through which fluid flowing out of the drain chamber 212 can flow out of the filter 10. When the valve core 12 is in the first position, the drain chamber 212 and the liquid outlet channel 113 are connected; when the valve core 12 is in the second position, the drain chamber 212 and the liquid outlet channel 113 can be connected or disconnected.

[0014] The filter screen 22 can be a plate-shaped mesh structure, with the inlet chamber 211 and the outlet chamber 212 located on opposite sides of the filter screen 22 along its thickness direction. Alternatively, the filter screen 22 can be a columnar mesh structure, with the inlet chamber 211 and the outlet chamber 212 located on the inner and outer sides of the filter screen 22, respectively; specifically, the inlet chamber 211 can be located inside the outlet chamber 212, or it can be located outside the outlet chamber 212.

[0015] The valve body 11 and the filter cover 21 can be respectively snapped into the fastener 3; or the valve body 11 and the filter cover 21 can be fitted together and snapped into the fastener 3, so that the fastener 3 can be snapped into the valve body 11 and the filter cover 21.

[0016] In this embodiment, by providing a valve assembly 1 and a filter assembly 2, the valve assembly 1 can manage the flow between the inlet channel 112 of the valve body 11 and the inlet chamber 211 of the filter cover 21. This allows for restriction of fluid entry into the inlet chamber 211 when the valve core 12 is in the second position, reducing the risk of leakage at the inlet channel of the valve body 11 when cleaning the filter residue of the filter assembly 2. The use of a snap-fit ​​element 3 to engage with the valve body 11 and the filter cover 21 reduces the difficulty of disassembling and assembling the valve body 11 and the filter cover 21, and also reduces the difficulty of cleaning the filter residue of the filter 10.

[0017] In some embodiments of this application, please refer to Figure 3 The filter screen 22 has a columnar mesh structure. The inlet chamber 211 is located inside the outlet chamber 212. One end of the filter screen 22 abuts against the valve body 11, and the other end of the filter screen 22 abuts against the inner wall of the filter cover 21.

[0018] In some embodiments of this application, the valve assembly 1 further includes a valve stem 13 and a knob 14. The valve stem 13 is rotatably disposed on the valve body 11 about its own axis, and the valve stem 13 is connected to the valve core 12. The knob 14 is provided with a mounting hole, into which the valve stem 13 is inserted.

[0019] In some embodiments of this application, please continue to refer to Figure 5 The valve body 11 has a first mounting surface 115, one end of the liquid inlet channel 112 extends to the valve cavity 111, the other end of the liquid inlet channel 112 extends to the first mounting surface 115, one end of the liquid outlet channel 113 extends to the valve cavity 111, and the other end of the liquid outlet channel 113 extends to the first mounting surface 115.

[0020] In this embodiment, one end of the inlet channel 112 and one end of the outlet channel 113 extend to the first mounting surface 115, allowing the valve chamber 111 to receive and discharge liquid on the same surface of the valve body 11. This filter 10 allows the first mounting surface 115 to be fitted onto the mounting surface of the target component, enabling the inlet channel 112 and outlet channel 113 to directly communicate with the flow path of the target component. On the one hand, this allows the filter 10 to be installed without damaging the structure of the target component, reducing the difficulty of installing the filter 10; on the other hand, it reduces the amount of piping required for installing the filter 10, saving on installation costs.

[0021] In some embodiments of this application, please refer to Figure 6 , Figure 6 for Figure 2 A partial enlarged view of region B. The valve body 11 includes a first annular protrusion 114, and the filter cover 21 includes a second annular protrusion 213. The second annular protrusion 213 is disposed opposite to the first annular protrusion 114. The fastener 3 is provided with a slot 31, and both the first annular protrusion 114 and the second annular protrusion 213 are engaged in the slot 31.

[0022] Both the first annular protrusion 114 and the second annular protrusion 213 are annular structures. In a projection plane perpendicular to the axis of the first annular protrusion 114, the orthographic projections of the first annular protrusion 114 and the second annular protrusion 213 at least partially overlap. It can be understood that the first annular protrusion 114 is the region of the valve body 11 that protrudes beyond the main body of the valve body 11. The second annular protrusion 213 is the region of the filter cover 21 that protrudes beyond the main body of the filter cover 21.

[0023] The number of slots 31 on the fastener 3 can be one or more. In an embodiment where the number of slots 31 on the fastener 3 is multiple, each slot 31 is fitted with a first annular protrusion 114 and a second annular protrusion 213. At least a portion of the first annular protrusion 114 and at least a portion of the second annular protrusion 213 are engaged in the slot 31.

[0024] In this embodiment, by setting the first annular protrusion 114 and the second annular protrusion 213 to be opposite each other, when the valve body 11 and the filter cover 21 are assembled, the first annular protrusion 114 can mate with the second annular protrusion 213, thereby achieving the mating of the valve body 11 and the filter cover 21. The locking groove 31 of the fastener 3 can lock the first annular protrusion 114 and the second annular protrusion 213, thereby fixing the valve body 11 and the filter cover 21 and achieving the assembly of the valve body 11 and the filter cover 21. When it is necessary to disassemble the valve body 11 and the filter cover 21, it is only necessary to pry the fastener 3 away from the valve body 11 and the filter cover 21 so that the first annular protrusion 114 and the second annular protrusion 213 disengage from the locking groove 31, thereby achieving the disassembly of the valve body 11 and the filter cover 21. This design makes the disassembly and assembly of the valve body 11 and the filter cover 21 convenient and quick, simplifies the assembly of the filter 10, and reduces the difficulty of cleaning the filter residue of the filter 10.

[0025] In some embodiments of this application, please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the snap fastener 3 provided in some embodiments of this application. The snap fastener 3 includes a connecting part 32 and two clamping parts 33. The connecting part 32 connects the two clamping parts 33. The two clamping parts 33 cooperate to clamp the valve body 11 and the filter cover 21. The clamping parts 33 are provided with a slot part 31.

[0026] Two clamping parts 33 respectively cooperate with the valve body 11 and the filter cover 21 on both sides. Both clamping parts 33 are provided with a slot 31. It is possible that only the clamping part 33 is provided with a slot 31; or it is possible that both the clamping part 33 and the connecting part 32 are provided with slots 31.

[0027] The clamping part 33 and the connecting part 32 can be integrally formed; for example, the clamping part 33 and the connecting part 32 can be integrally injection molded. Alternatively, the clamping part 33 and the connecting part 32 can be separately provided and connected; for example, the clamping part 33 and the connecting part 32 can be welded together.

[0028] In this embodiment, both clamping parts 33 are provided with slots 31. The slots 31 of both clamping parts 33 can lock the first annular protrusion 114 and the second annular protrusion 213, so that the fastener 3 can lock the first annular protrusion 114 and the first annular protrusion 213 on both sides of the valve body 11 and the filter cover 21, and can also clamp the valve body 11 and the filter cover 21, thereby improving the fixing effect of the fastener 3 on the valve body 11 and the filter cover 21 and improving the structural stability of the filter 10.

[0029] In some embodiments of this application, please refer to Figure 8 , Figure 8This is a schematic diagram of the structure of the snap fastener 3 provided in some embodiments of this application. The clamping part 33 includes a first straight section 331 and an arc-shaped section 332. The first straight section 331 connects the arc-shaped section 332 and the connecting part 32. The first straight sections 331 of the two clamping parts 33 are arranged opposite to each other. The two arc-shaped sections 332 cooperate to clamp the valve body 11 and the filter cover 21. At least a portion of the slot part 31 is located in the arc-shaped section 332.

[0030] The first straight section 331, the arc-shaped section 332, and the connecting part 32 can be integrally bent. Alternatively, the first straight section 331, the arc-shaped section 332, and the connecting part 32 can be separately arranged and connected; for example, the first straight section 331, the arc-shaped section 332, and the connecting part 32 can be welded together. The first straight sections 331 of the two clamping parts 33 are arranged opposite each other on both sides of the connecting part 32. It is possible that only a part of the slot part 31 is arranged on the arc-shaped section 332, and the other part is arranged on the first straight section 331; or the entire slot part 31 is arranged on the arc-shaped section 332.

[0031] In this embodiment, the first straight section 331 of the clamping part 33 can enhance the structural strength of the arc-shaped section 332. The arc-shaped sections 332 of the two clamping parts 33 cooperate to clamp the valve body 11 and the filter cover 21. On the one hand, the arc-shaped sections 332 of the two clamping parts 33 can adapt to the outer shape of the first annular protrusion 114 and the second annular protrusion 213 through their arc-shaped structure, which is conducive to increasing the contact area between the groove wall of the slot part 31 and the first annular protrusion 114 and the second annular protrusion 213, making the fixing effect of the slot part 31 on the first annular protrusion 114 and the second annular protrusion 213 more stable. On the other hand, the arc-shaped sections 332 of the two clamping parts 33 can encircle at least a part of the valve body 11 and the filter cover 21, thereby reducing the risk of the fastener 3 detaching from the valve body 11 and the filter cover 21, improving the assembly stability of the fastener 3, and thus improving the assembly stability of the valve body 11 and the filter cover 21.

[0032] In some embodiments of this application, please continue to refer to Figure 7 and Figure 8 The clamping part 33 also includes a second straight section 333, and an arc-shaped section 332 connects the second straight section 333 and the first straight section 331. A flared part 34 is formed between the second straight sections 333 of the two clamping parts 33.

[0033] The fastener 3 has an opening on the side opposite to the connecting part 32, through which the valve body 11 and the filter cover 21 can enter between the two arc-shaped segments 332, so that the two arc-shaped segments 332 can cooperate to clamp the valve body 11 and the filter cover 21. Along the direction of the connecting part 32 towards the opening, the distance between the second straight segments 333 of the two clamping parts 33 gradually increases, so that a flared part 34 is formed between the second straight segments 333 of the two clamping parts 33.

[0034] In this embodiment, an arc-shaped segment 332 connects the first straight segment 331 and the second straight segment 333. The second straight segment 333 is located on the side of the arc-shaped segment 332 away from the connecting portion 32, and a flared portion 34 is formed between the second straight segments 333 of the two clamping portions 33. This facilitates the first annular protrusion 114 of the valve body 11 and the second annular protrusion 213 of the filter cover 21 entering the area framed by the arc-shaped segment 332 of the two clamping portions 33 through the flared portion 34, reducing the assembly difficulty of the fastener 3 with the valve body 11 and the filter cover 21. The flared portion 34 also helps reduce the risk of the arc-shaped segment 332 scratching the valve body 11 or the filter cover 21, thus extending the service life of the filter 10.

[0035] In some embodiments of this application, please continue to refer to Figure 7 and Figure 8 The slot portion 31 includes a first slot segment 311, a second slot segment 312, and a third slot segment 313. The second slot segment 312 connects the first slot segment 311 and the third slot segment 313. The first slot segment 311 is located on the first straight segment 331, the second slot segment 312 is located on the arc segment 332, and the third slot segment 313 is located on the second straight segment 333.

[0036] The first groove segment 311, the second groove segment 312, and the third groove segment 313 are connected. The two ends of the arc segment 332 are respectively connected to the first straight segment 331 and the second straight segment 333. The second groove segment 312 passes through both ends of the arc segment 332 to connect the first groove segment 311 and the third groove segment 313.

[0037] In this embodiment, the first groove segment 311 is disposed on the first straight segment 331. After the valve body 11 and the filter cover 21 are assembled to the fastener 3, on the one hand, the first groove segment 311 can provide clearance space for the first annular protrusion 114 and the second annular protrusion 213, so that the second groove segment 312 can hold more areas of the first annular protrusion 114 and the second annular protrusion 213; on the other hand, the first groove segment 311 can also hold the first annular protrusion 114 and the second annular protrusion 213, thereby improving the restriction effect of the groove portion 31 on the first annular protrusion 114 and the second annular protrusion 213. The second groove segment 312 is disposed on the arc segment 332. The second groove segment 312 connects the first groove segment 311 and the third groove segment 313, so that the second groove segment 312 penetrates the arc segment 332, thereby giving the second groove segment 312 a larger length. This is beneficial to increasing the contact area between the second groove segment 312 and the first annular protrusion 114 and the second annular protrusion 213, and improving the limiting effect of the second groove segment 312 on the first annular protrusion 114 and the second annular protrusion 213. The third groove segment 313 is disposed on the second straight segment 333. The flared portion 34 formed between the second straight segments 333 of the two clamping portions 33 makes the slot portion 31 have a larger size on the third groove segment 313. On the one hand, it is beneficial for the first annular protrusion 114 and the second annular protrusion 213 to be inserted into the slot portion 31, reducing the assembly difficulty of the fastener 3, valve body 11 and filter cover 21. On the other hand, the third groove segment 313 can provide clearance space for the first annular protrusion 114 and the second annular protrusion 213 to be inserted into the second groove segment 312, improving the restriction effect of the second groove segment 312 on the first annular protrusion 114 and the second annular protrusion 213.

[0038] In some embodiments of this application, please refer to Figure 9 , Figure 9 This is a schematic diagram of the structure of the valve core 12 provided in some embodiments of this application. The valve body 11 also includes a liquid outlet channel 113. When the valve core 12 is in the first position, the liquid outlet channel 113 is connected to the liquid discharge chamber 212. When the valve core 12 is in the second position, the liquid outlet channel 113 is disconnected from the liquid discharge chamber 212.

[0039] In some embodiments of this application, please continue to refer to Figure 9 And further refer to Figure 10 , Figure 10 This is a schematic diagram of the structure of the valve core 12 provided in some embodiments of this application. The valve core 12 is provided with a first connecting channel 121 and a second connecting channel 122. When the valve core 12 is in the first position, the liquid inlet channel 112 is connected to the liquid inlet chamber 211 through the first connecting channel 121, and the liquid outlet channel 113 is connected to the liquid outlet chamber 212 through the second connecting channel 122.

[0040] The first connecting channel 121 includes a first channel 1211 and a second channel 1212. The axis of the first channel 1211 coincides with or is parallel to the first axis, and the axis of the second channel 1212 is perpendicular to the first axis. The first channel 1211 is connected to the liquid inlet chamber 211. When the valve core 12 is in the first position, the second channel 1212 is connected to the liquid inlet channel 112. When the valve core 12 is in the second position, the second channel 1212 is disconnected from the liquid inlet channel 112.

[0041] In some embodiments of this application, the valve core 12 is rotatably disposed in the valve cavity 111 about the axis of the first channel 1211. The second communication channel 122 includes a third channel 1221 and a plurality of fourth channels 1222. The axis of the third channel 1221 is perpendicular to the axis of the first channel 1211, and the plurality of fourth channels 1222 are spaced apart around the axis of the third channel 1221. The plurality of fourth channels 1222 communicate with the drain cavity 212. When the valve core 12 is in the first position, the third channel 1221 communicates with the outlet channel 113. When the valve core 12 is in the second position, the third channel 1221 is disconnected from the outlet channel 113.

[0042] In some embodiments of this application, please refer to Figure 3 and Figure 11 , Figure 11 This is a schematic diagram of the structure of the valve assembly 1 provided in some embodiments of this application. A flow gap 1111 is formed between the outer wall of the valve core 12 and the cavity wall of the valve cavity 111. The valve body 11 is provided with a flow hole portion 116. A plurality of fourth channels 1222 communicate with the flow gap 1111. The flow gap 1111 communicates with the drain cavity 212 through the flow hole portion 116.

[0043] In some embodiments of this application, there are multiple fourth channels 1222, which are arranged circumferentially around the third channel 1221.

[0044] In some embodiments of this application, please refer to Figure 12 , Figure 12 This is a schematic diagram of the structure of a filter cover 21 provided in some embodiments of this application. The filter cover 21 is provided with a protrusion 214, which extends to the liquid inlet chamber 211 and has a receiving cavity 2141. The filter assembly 2 also includes a magnetic suction member 23, which is disposed in the receiving cavity 2141.

[0045] The magnetic attractor 23 can be an electromagnet or a permanent magnet.

[0046] The receiving cavity 2141 can be a closed chamber, and the receiving cavity 2141 is not connected to the outside of either the liquid inlet cavity 211 or the filter cover 21. Alternatively, the receiving cavity 2141 can have an opening 215, and the receiving cavity 2141 is connected to the outside of either the liquid inlet cavity 211 or the filter cover 21.

[0047] The filter cover 21 may include a bottom wall and a side wall, with the side wall surrounding the bottom wall and the bottom wall located at one end of the side wall. The second annular protrusion 213 is located on the side wall away from the bottom wall. The protrusion 214 may be located on the bottom wall or on the side wall.

[0048] In this embodiment, the fluid flowing into the filter cover 21 through the liquid inlet channel 112 passes through the protrusion 214. The magnetic attractor 23 inside the protrusion 214 can attract magnetic impurities in the fluid, thereby retaining the magnetic impurities in the fluid in the liquid inlet chamber 211 and improving the filtration effect of the filter 10 on the fluid.

[0049] In some embodiments of this application, please refer to Figure 13 , Figure 13 This is a schematic diagram of the structure of a filter cover 21 provided in some embodiments of this application. A receiving cavity 2141 extends to the outer wall of the filter cover 21 and forms an opening 215. The filter assembly 2 also includes a sealing member 4, which is connected to the filter cover 21 and seals the opening 215.

[0050] The receiving cavity 2141 extends to the outer wall of the filter cover 21 and forms an opening 215, allowing the receiving cavity 2141 to communicate with the outside of the filter cover 21. The sealing member 4 is connected to the filter cover 21, which can be an interference fit between the sealing member 4 and the filter cover 21; a snap-fit ​​between the sealing member 4 and the filter cover 21; or a threaded connection between the sealing member 4 and the filter cover 21. Figure 13 In the illustrated embodiment, the sealing member 4 is provided with an external thread, and the cavity wall of the receiving cavity 2141 is provided with an internal thread that matches the external thread.

[0051] In this embodiment, by providing a receiving cavity 2141 extending to the outer wall of the filter cover 21 and forming an opening 215, the magnetic component can be assembled into the receiving cavity 2141 through the opening 215, reducing the difficulty of assembling the magnetic component. The sealing component 4 can seal the opening 215 and connect to the filter cover 21. The sealing component 4 can keep the magnetic component in the receiving cavity 2141, reducing the risk of the magnetic component detaching from the receiving cavity 2141 when the filter 10 filters fluid, and improving the assembly stability of the magnetic component.

[0052] Please continue to refer to Figure 1 This application provides an integrated component 100, including a flow channel plate 20 and a filter 10 provided in any of the above embodiments, wherein the valve body 11 of the filter 10 is mounted on the flow channel plate 20.

[0053] The flow channel plate 20 can be provided with flow channels, which can integrate components such as liquid pump, valve body 11 and liquid storage tank into the flow channel plate 20, and connect the various components through the internal flow channels of the flow channel plate 20.

[0054] In this embodiment, the valve body 11 of the filter 10 is installed on the flow channel plate 20. The filter 10 can filter the fluid in the flow channel of the flow channel plate 20, thereby improving the service life of the fluid in the flow channel plate 20.

[0055] In some embodiments of this application, the valve body 11 further includes a liquid outlet channel 113, which communicates with the drain chamber 212 when the valve core 12 is in the first position. The valve body 11 has a first mounting surface 115, one end of the liquid inlet channel 112 extends to the valve chamber 111, and the other end of the liquid inlet channel 112 extends to the first mounting surface 115. One end of the liquid outlet channel 113 extends to the valve chamber 111, and the other end of the liquid outlet channel 113 extends to the first mounting surface 115. The flow channel plate 20 has a second mounting surface 201, and the flow channel plate 20 is provided with a first flow channel 202 and a second flow channel 203. One end of the first flow channel 202 extends to the second mounting surface 201, and one end of the second flow channel 203 extends to the second mounting surface 201. The first mounting surface 115 and the second mounting surface 201 are sealed together. The first flow channel 202 communicates with the liquid inlet channel 112, and the second flow channel 203 communicates with the liquid outlet channel 113.

[0056] The second mounting surface 201 of the flow channel plate 20 is correspondingly disposed to the first mounting surface. When the filter 10 is assembled to the flow channel plate 20, the first mounting surface 115 of the filter 10 is in contact with the second mounting surface 201 of the flow channel plate 20. The first mounting surface 115 and the second mounting surface 201 can be tightly fitted to achieve a sealed connection. Alternatively, the first mounting surface 115 and the second mounting surface 201 can be sealed together via an intermediate component; the intermediate component can be a gasket, sealing ring, etc.

[0057] One end of the first flow channel 202 extends to the second mounting surface 201, allowing the first flow channel 202 to communicate with the outside through the second mounting surface 201. One end of the second flow channel 203 extends to the second mounting surface 201, allowing one end of the second flow channel 203 to communicate with the outside through the second mounting surface 201. When the first mounting surface 115 and the second mounting surface 201 are sealed together, the first flow channel 202 and the liquid inlet channel 112 are connected, allowing the first flow channel 202 and the liquid inlet channel 112 to communicate. The second flow channel 203 and the liquid outlet channel 113 are connected, allowing the second flow channel 203 and the liquid outlet channel 113 to communicate.

[0058] In this embodiment, both the first flow channel 202 and the second flow channel 203 of the flow channel plate 20 extend to the second mounting surface 201. The filter 10 is disposed on the second mounting surface 201, so that the first mounting surface 115 and the second mounting surface 201 are sealed together, enabling flow control between the first flow channel 202 and the second flow channel 203. Moreover, flow control between the first flow channel 202 and the second flow channel 203 can be achieved with only one filter 10, reducing the piping setup required for flow control and saving the installation cost of the integrated component 100.

[0059] In some embodiments of this application, the flow channel wall of the first flow channel 202 of the flow channel plate 20 includes a flow guiding structure, and the flow guiding structure and the flow channel opening of the first flow channel 202 are inclined to reduce the flow resistance of the fluid medium in the first flow channel 202.

[0060] In some embodiments of this application, the integrated component 100 further includes a first seal 30 and a second seal 40, and the first mounting surface 115 and the second mounting surface 201 are sealed together by the first seal 30 and the second seal 40. Specifically, an inlet channel 112 extends to one end of the first mounting surface 115 to form an inlet portion 1121, and an outlet channel 113 extends to one end of the first mounting surface 115 to form an outlet portion 1131. The first seal 30 is disposed around the inlet portion 1121, and the second seal 40 is disposed around the outlet portion 1131.

[0061] The first seal 30 and the second seal 40 can be separate components. Alternatively, the first seal 30 and the second seal 40 can be integrally formed.

[0062] An inlet portion 1121 is located on the first mounting surface 115. A first seal 30 is disposed around the inlet portion 1121, and the first seal 30 can limit the overflow of fluid medium from the inlet portion 1121 of the liquid inlet channel 112 to the valve body 11 and the flow channel plate 20. An outlet portion 1131 is located on the first mounting surface 115. A second seal 40 is disposed around the outlet portion 1131, and the second seal 40 can limit the overflow of fluid medium from the outlet portion 1131 of the liquid outlet channel 113 to the valve body 11 and the flow channel plate 20. The first seal 30 and the second seal 40 respectively seal the two communicating areas of the filter 10 and the flow channel plate 20, reducing the risk of fluid medium overflow.

[0063] In this embodiment, by providing a first seal 30 and a second seal 40 to seal the first mounting surface 115 and the second mounting surface 201, the risk of fluid medium overflowing from the flow channel plate 20 and the filter 10 can be reduced, thereby improving the stability and reliability of the fit between the flow channel plate 20 and the filter 10.

[0064] In some embodiments of this application, the first seal 30 and the second seal 40 are integrally formed.

[0065] The first seal 30 and the second seal 40 can be integrally injection molded, integrally die-cast, etc.

[0066] In this embodiment, by integrally molding the first sealing element 30 and the second sealing element 40, the sealing effect of the first sealing element 30 and the second sealing element 40 on the first mounting surface 115 and the second mounting surface 201 can be improved. It also reduces the risk of loss of the first sealing element 30 or the second sealing element 40 during storage or transportation.

[0067] In some embodiments of this application, the first mounting surface 115 is provided with a first limiting groove 1151, and at least a portion of the first sealing member 30 is accommodated in the first limiting groove 1151.

[0068] The first sealing member 30 may be entirely contained within the first limiting groove 1151, and a first protrusion 214 may be provided on the second mounting surface 201 at a position corresponding to the first limiting groove 1151. The first protrusion 214 is embedded in the first limiting groove 1151 and abuts against the first sealing member 30 to seal the first mounting surface 115 and the second mounting surface 201.

[0069] Alternatively, only a portion of the first sealing member 30 may be accommodated within the first limiting groove 1151, while the other portion protrudes from the first limiting groove 1151. The portion of the first sealing member 30 located outside the first limiting groove 1151 abuts against the second mounting surface 201 to seal the first mounting surface 115 and the second mounting surface 201.

[0070] When the filter 10 is assembled to the flow channel plate 20, the surface of the first seal 30 facing the second mounting surface 201 can be flush with the first mounting surface 115 and abut against the second mounting surface 201 to seal the first mounting surface 115 and the second mounting surface 201.

[0071] In this embodiment, by setting at least a portion of the first sealing member 30 to be accommodated in the first limiting groove 1151, the position of the first sealing member 30 can be made more stable, thereby improving the sealing effect of the first sealing member 30 on the first mounting surface 115 and the second mounting surface 201.

[0072] In some embodiments of this application, the first mounting surface 115 is provided with a second limiting groove 1152, and at least a portion of the second seal 40 is accommodated in the second limiting groove 1152.

[0073] The second sealing member 40 may be entirely contained within the second limiting groove 1152. A second protrusion 214 is provided on the second mounting surface 201 at a position corresponding to the second limiting groove 1152. The second protrusion 214 is embedded in the second limiting groove 1152 and abuts against the second sealing member 40 to seal the first mounting surface 115 and the second mounting surface 201.

[0074] Alternatively, only a portion of the second seal 40 may be contained within the second limiting groove 1152, while the other portion may protrude from the second limiting groove 1152. The portion of the second seal 40 located outside the second limiting groove 1152 abuts against the second mounting surface 201 to seal the first mounting surface 115 and the second mounting surface 201.

[0075] When the filter 10 is assembled to the flow channel plate 20, the surface of the second seal 40 facing the second mounting surface 201 can be flush with the first mounting surface 115 and abut against the second mounting surface 201 to seal the first mounting surface 115 and the second mounting surface 201.

[0076] In this embodiment, by setting at least a portion of the second sealing member 40 to be accommodated within the second limiting groove 1152, the position of the second sealing member 40 can be made more stable, thereby improving the sealing effect of the second sealing member 40 on the first mounting surface 115 and the second mounting surface 201.
