Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve technology, specifically relating to a high-flow electromagnetic valve device with a filtration structure. Background Technology

[0002] Currently, solenoid valves are widely used in household appliances, and with end users' increasing awareness of drinking water safety and health, water quality varies greatly in actual applications, necessitating water filtration. A patent with publication number CN220850958U discloses a normally open valve, including a valve seat, an electromagnetic assembly, a diaphragm assembly, a return spring, a piston assembly, a guide cylinder, and a positioning plug. The guide cylinder is fixed to the valve seat and has an iron core for the electromagnetic assembly and a sliding channel for the piston assembly. The diaphragm assembly is located between the back pressure chamber, inlet chamber, and outlet chamber of the valve seat. When energized, the electromagnetic assembly uses the iron core to move the piston assembly closer to the diaphragm assembly and adjust the pressure of the back pressure chamber to cut off the passage between the inlet and outlet chambers. The return spring has an elastic tendency to pull the piston assembly back to its original position in its natural state. During power-off, the guide cylinder and positioning plug can be engaged through a snap-fit ​​structure, allowing the piston assembly to retract into the sliding channel. This design ensures that the positioning plug is not easily dislodged and that the valve can still start and stop normally even in a failure state. Existing valve bodies have inlet and outlet chambers, but no filter structure is installed between them. This results in poor water quality from the valve body, affecting the user experience. Therefore, a high-flow-rate solenoid valve device with a filter structure needs to be designed to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a high-flow-rate solenoid valve device with a filtration structure. The invention incorporates a filtration component in the water inlet channel of the valve body, achieving dual filtration through a first filter element and a second filter element, resulting in good overall filtration performance and a stable and reliable filtration structure.

[0004] The objective of this invention is achieved through the following technical solution: a high-flow-rate solenoid valve device with a filtration structure, comprising a valve body, with an inlet channel and an outlet channel at both ends of the valve body; an solenoid valve assembly and a sealing assembly at the open end of the valve body, with a back pressure chamber between the solenoid valve assembly and the sealing assembly; a first adapter assembly on the outlet channel, and a second adapter assembly on the inlet channel; an inlet chamber within the inlet channel, with a filtration assembly between the inlet chamber and the second adapter assembly, the filtration assembly comprising a first filter element and a second filter element.

[0005] Preferably, the solenoid valve assembly includes a coil body, an iron core, and a rubber core, with the coil body disposed on the outer layer of the iron core; the iron core and the rubber core are fixedly connected, and a pressure relief chamber communicating with the water outlet channel is provided below the back pressure chamber; a sealing assembly is provided at the opening end of the pressure relief chamber, and the rubber core abuts against the sealing assembly in the default state.

[0006] Preferably, the sealing assembly includes a sealing ring frame and a sealing ring body, and the sealing assembly is mounted on the valve body; the sealing ring body is mounted on the sealing ring frame, and the edge of the sealing ring body abuts against the inner wall of the valve body; the sealing ring frame is provided with a side hole, which connects the back pressure chamber and the water inlet chamber.

[0007] When the coil body on the solenoid valve assembly is de-energized, the iron core will not engage, causing the rubber core to press against the through hole of the sealing ring holder. At this time, water flows from the inlet chamber into the back pressure chamber along the side hole on the sealing ring holder, creating back pressure in the back pressure chamber. The rubber core then blocks the through hole of the sealing ring holder, and the sealing ring body blocks the inner edge of the valve body, isolating the back pressure chamber from the outlet channel. When the coil body on the solenoid valve assembly is energized, the electromagnetic field generated by the solenoid valve assembly lifts the iron core, and the water in the back pressure chamber flows along the through hole of the sealing ring holder to the pressure relief chamber. The water pressure in the back pressure chamber decreases, and the water pressure in the inlet chamber pushes up the sealing ring body, opening the seal body from the valve body. Water flows in large quantities from the inlet chamber into the pressure relief chamber, and then from the pressure relief chamber to the outlet channel.

[0008] Preferably, the filter assembly further includes a first sealing ring and a second sealing ring; the first sealing ring is installed on the first filter element, and the second sealing ring is installed on the second filter element.

[0009] Preferably, the first filter element and the second filter element are rotatably snapped together; the first filter element is provided with a limiting post, and the second filter element is provided with a limiting groove, the outer contour of the limiting post and the outer contour of the limiting groove being adapted to each other.

[0010] Preferably, a spacer is provided between the first filter element and the second adapter assembly; the second adapter assembly includes a second tube claw, a second threaded cap and a pair of third sealing rings, and the spacer is installed between the first filter element and the second tube claw.

[0011] Preferably, the second threaded cap is threadedly connected to the first filter element, and the second tube claw is snapped onto the second threaded cap; a pair of third sealing rings are provided between the pad and the second tube claw; the third sealing ring is tightly fitted onto the inner wall of the first filter element; the first filter element is threadedly connected to the valve body, the pad is installed on the step inside the first filter element, and the pad is fitted with the third sealing ring; the second tube claw is oriented towards the third sealing ring.

[0012] The first and second filter elements can be made of different filter materials according to different usage scenarios, which makes them more versatile. At the same time, the mesh count of the first filter element and the mesh count of the second filter element can be adapted and adjusted, making them suitable for a wide range of applications.

[0013] The first and second filter elements are connected by a rotating snap-fit, allowing them to be disassembled. The first filter element is threaded to the valve body and can be used independently. The first and second filter elements can also be used together, offering good versatility. The use of a first and second sealing ring improves the sealing effect. When the valve body deforms during use, the first and second sealing rings provide a double seal, preventing liquid leakage. A second adapter assembly facilitates connection between the inlet pipe and the inlet channel. The connection method, using a second pipe claw and a second threaded cap, makes the overall connection more stable and effectively prevents the inlet pipe from detaching.

[0014] Preferably, the first adapter assembly includes a first tube claw, a first threaded cap, and a pair of fourth sealing rings. The first threaded cap is threadedly connected to the valve body, and the first threaded cap is provided with a first tube claw that is snapped into it. The fourth sealing ring is tightly fitted on the step of the valve body, and the first tube claw is positioned toward the fourth sealing ring.

[0015] By incorporating a first adapter component, the connection between the outlet pipe and the outlet channel is facilitated. Even in extreme cases of valve body deformation, the first threaded cap and the first pipe claw ensure a stable connection of the outlet pipe, preventing it from detaching and making the process safer and more reliable.

[0016] Compared with the prior art, the present invention has the following advantages: 1. By setting a filter component in the water inlet channel of the valve body, impurities in the water flow are prevented from entering the valve body, resulting in better water quality discharged from the valve body; 2. The first filter element and the second filter element are detachably connected and can be used in combination; the first filter element can also be used independently, resulting in better overall versatility; 3. By setting the first adapter component and the second adapter component, it is convenient to connect the valve body to external pipelines, making the connection convenient and the use process safe and reliable.

[0019] The solenoid valve assembly 4 includes a coil body 41, an iron core 42, and a rubber core 43. The coil body 41 is disposed on the outer layer of the iron core 42. The iron core 42 and the rubber core 43 are fixedly connected. A pressure relief chamber 11 communicating with the water outlet channel 3 is provided below the back pressure chamber 6. A sealing assembly 5 is provided at the open end of the pressure relief chamber 11. In the default state, the rubber core 43 abuts against the sealing assembly 5. The sealing assembly 5 includes a sealing ring frame 51 and a sealing ring body 52. ​​The sealing assembly 5 is installed on the valve body 1. The sealing ring body 52 is installed on the sealing ring frame 51, and the edge of the sealing ring body 52 abuts against the inner wall of the valve body 1. The sealing ring frame 51 is provided with a side hole 53, which communicates with the back pressure chamber 6 and the water inlet chamber 10.

[0020] The filter assembly 9 further includes a first sealing ring 93 and a second sealing ring 94; the first sealing ring 93 is installed on the first filter element 91, and the second sealing ring 94 is installed on the second filter element 92. The first filter element 91 and the second filter element 92 are rotatably snapped together; the first filter element 91 is provided with a limiting post 95, and the second filter element 92 is provided with a limiting groove 96, the outer contour of the limiting post 95 and the outer contour of the limiting groove 96 are adapted to each other. A pad post 12 is provided between the first filter element 91 and the second adapter assembly 8; the second adapter assembly 8 includes a second tube claw 81, a second threaded cap 82, and a pair of third sealing rings 83, and the pad post 12 is installed between the first filter element 91 and the second tube claw 81. The second threaded cap 82 is threadedly connected to the first filter element 91, and the second tube claw 81 is snapped onto the second threaded cap 82; a pair of third sealing rings 83 are provided between the pad 12 and the second tube claw 81; the third sealing ring 83 is tightly fitted onto the inner wall of the first filter element 91; the first filter element 91 is threadedly connected to the valve body 1, and the pad 12 is installed on the step inside the first filter element 91, with the pad 12 and the third sealing ring 83 fitting together; the second tube claw 81 is positioned towards the third sealing ring 83. The first adapter assembly 7 includes a first tube claw 71, a first threaded cap 72, and a pair of fourth sealing rings 73.

[0021] The specific operation process of this embodiment is as follows: when the coil body 41 on the solenoid valve assembly 4 is de-energized, the iron core 42 will not be attracted, so that the rubber core 43 abuts against the through hole of the sealing ring frame 51; at this time, the water flows from the water inlet chamber 10 into the back pressure chamber 6 along the side hole 53 on the sealing ring frame 51; so that back pressure is generated in the back pressure chamber 6, then the rubber core 43 will block the through hole of the sealing ring frame 51 and the sealing ring body 52 will block the inner edge of the valve body 1, and the back pressure chamber 6 and the water outlet channel 3 are in a state of isolation. When the coil body 41 on the solenoid valve assembly 4 is energized, the electromagnetic field force generated by the solenoid valve assembly 4 causes the iron core 42 to rise. The water flow in the back pressure chamber 6 flows along the through hole of the sealing ring frame 51 to the pressure relief chamber 11. The water pressure in the back pressure chamber 6 decreases, and the water pressure in the inlet chamber 10 pushes up the sealing ring body 52. ​​The sealing ring body 52 and the valve body 1 are in the open state, and the water flow enters the pressure relief chamber 11 in large quantities from the inlet chamber 10, and then flows from the pressure relief chamber 11 to the outlet channel 3.

[0022] The first filter element 91 and the second filter element 92 can be selected with different filter materials according to different usage scenarios, which makes them more versatile. At the same time, the mesh count of the first filter element 91 and the mesh count of the second filter element 92 can be adapted and adjusted, making them suitable for a wide range of applications.

[0023] The first filter element 91 and the second filter element 92 are connected by a rotating snap-fit, allowing them to be disassembled. The first filter element 91 is threaded to the valve body 1 and can be used independently. The first filter element 91 and the second filter element 92 can also be used in combination, offering good versatility. The use of a first sealing ring 93 and a second sealing ring 94 improves the sealing effect. When the valve body 1 deforms during use, the first sealing ring 93 and the second sealing ring 94 provide a double seal, preventing liquid leakage. The second adapter assembly 8 facilitates the connection between the inlet pipe and the inlet channel 2. The connection method using the second pipe claw 81 and the second threaded cap 82 makes the overall connection process more stable and effectively prevents the inlet pipe from detaching.

[0024] By setting the first adapter component 7, it is convenient to connect the water outlet pipe to the water outlet channel 3. When the valve body 1 is deformed in extreme cases, the first threaded cap 72 and the first pipe claw 71 can also stabilize the connection of the water outlet pipe, prevent the water outlet pipe from detaching, and make the use process safer and more reliable.
