[0042] This application provides a valve body, such as... Figures 1 to 7 As shown, the valve body includes:

[0043] Casing 9;

[0044] Iron core 10, wherein the iron core 10 is disposed within the housing 9;

[0045] The outer wall of the iron core 10 is provided with a groove 120, which cooperates with the housing 9 to form a first flow channel 100, which is suitable for connecting the flow channel of the application device.

[0046] Specifically, the valve body includes a housing 9 and an iron core 10. The iron core 10 is disposed inside the housing 9; the outer wall of the iron core 10 is provided with a groove 120, which cooperates with the housing 9 to form a first flow channel 100, which is suitable for connecting to the flow channel of the application equipment.

[0047] The valve body of this application has a groove on the outer wall of the iron core. The groove cooperates with the shell to form a first flow channel. The first flow channel is connected to the flow channel of the application equipment, so that the fluid flows through the inside of the valve body to the flow channel of the application equipment, thereby reducing the volume of the valve body.

[0048] Compared to existing technologies, the valve body of this application is smaller in size, which reduces the installation volume of the valve body in the application equipment. Furthermore, the internal flow channel simplifies the flow channel structure design and reduces the complexity of the connection structure with the external flow channels of the application equipment. Moreover, the flow channel of the valve body in this application is arranged along the axial direction of the valve body, allowing fluid to flow in from the bottom and out from the top. This flow channel layout ensures that the fluid flow direction is consistent with the valve body assembly direction, reducing the assembly difficulty of the valve body in the application equipment and improving the overall integration of the valve body.

[0049] In some embodiments, the groove 120 includes a first groove 81, the first flow channel 100 includes a first flow channel segment 101, and the iron core 100 includes:

[0050] The moving iron core 8 has the first groove 81 on its outer surface, and the first groove 81 cooperates with the housing 9 to form the first flow channel section 101.

[0051] Optional, such as Figure 1 and Figure 2 As shown, the groove 120 includes a first groove 81, the first flow channel 100 includes a first flow channel section 101, the iron core 10 includes a moving iron core 8, the outer surface of the moving iron core 8 is provided with the first groove 81, and the first groove 81 cooperates with the housing 9 to form the first flow channel section 101.

[0052] Typically, the outer surface of the moving iron core 8 is provided with multiple first grooves 81, which cooperate with the housing 9 to form multiple first flow channel sections 101. Providing first grooves 81 on the outer surface of the moving iron core 8 and forming first flow channel sections 101 through the cooperation of the first grooves 81 with the housing 9 simplifies the flow channel structure inside the valve body and reduces the processing requirements of the external flow channel of the application equipment.

[0053] In some embodiments, the groove 120 includes a second groove 45, the first flow channel 100 includes a second flow channel segment 102, and the iron core 10 includes:

[0054] The stationary iron core 4 has a second groove 45 on its outer surface, and the second groove 45 cooperates with the housing 9 to form the second flow channel section 102.

[0055] The second flow channel section 102 is connected to the first flow channel section 101.

[0056] Optional, such as Figure 3 , Figure 4 As shown, the groove 120 further includes a second groove 45, the first flow channel 100 includes a second flow channel section 102, and the iron core 10 includes a stationary iron core 4, wherein the stationary iron core 4 is fixedly connected to the housing 9. The outer surface of the stationary iron core 4 is provided with a second groove 45, which cooperates with the housing 9 to form a second flow channel section 102, wherein the second flow channel section 102 communicates with the first flow channel section 101.

[0057] Typically, the outer surface of the stationary iron core 4 is provided with multiple second grooves 45, which cooperate with the housing 9 to form multiple second flow channel sections 102. Providing second grooves 45 on the outer surface of the stationary iron core 4, and forming second flow channel sections 102 through the cooperation of the second grooves 451 with the housing 9, further simplifies the flow channel structure inside the valve body. Simultaneously, the multiple second flow channel sections 102 are paired and connected with multiple first flow channel sections 101, enabling fluid flow between the moving iron core and the stationary iron core.

[0058] In some embodiments, the valve body includes:

[0059] The third flow channel section 103 is disposed inside the stationary iron core 4 along the first direction, and the third flow channel section 103 is connected to the second flow channel section 102.

[0060] Optionally, a third flow channel section 103 is provided inside the stationary iron core of the valve body. The third flow channel section 103 is disposed inside the stationary iron core 4 along a first direction and communicates with the second flow channel section 102. The first direction is the radial direction of the stationary iron core. The communication between the third flow channel section 103 and the second flow channel section 102 allows the fluid to pass through the interior of the stationary iron core 4 and connect with the application equipment, further reducing the complexity of the external flow channel and also reducing the weight of the valve body, thus achieving a lightweight valve body.

[0061] In some embodiments, the valve body includes a fourth flow channel section 104 disposed inside the stationary iron core 4 along a second direction, and the fourth flow channel section 104 communicates with the third flow channel section 103.

[0062] Optionally, a fourth flow channel section 104 is also provided inside the stationary iron core 4. The fourth flow channel section 104 is arranged inside the stationary iron core 4 along the second direction and communicates with the third flow channel section 103. The second direction is the direction along the axial direction of the stationary iron core 4. The communication between the fourth flow channel section 104 and the third flow channel section 103 allows the fluid to be connected to the application equipment through the fourth flow channel section 104. The fourth flow channel section 104 is the outflow channel of the fluid. The fourth flow channel section 104 makes the outlet of the valve body set along the axial direction of the valve body, further optimizing the fluid flow path, reducing the intersection design between the internal flow channel of the valve body and the external flow channel of the application equipment, and at the same time, it can further reduce the weight of the valve body, realizing the lightweighting of the valve body.

[0063] In some embodiments, the iron core 10 includes:

[0064] Spring 6, one end of which is connected to the stationary iron core 4, and the other end of which is connected to the moving iron core 8.

[0065] Optionally, the iron core 10 also includes a spring 6, one end of which is connected to the stationary iron core 4, and the other end is connected to the moving iron core 8. The stationary iron core 4 and the moving iron core 8 move relative to each other through the restoring force of the spring 6. Because the stationary iron core 4 is connected to the housing, it remains stationary, while the spring 6 drives the moving iron core 8 to reciprocate along the axial direction of the valve body within the housing. The spring 6 connects the stationary iron core 4 and the moving iron core 8, providing a restoring force for the moving iron core 8 and improving the reliability of the valve body.

[0066] In some embodiments, the stationary iron core 4 includes:

[0067] The first receiving cavity 47 is disposed at one end of the stationary iron core 4 near the moving iron core 8, and the first receiving cavity 47 is used to assemble the spring 6.

[0068] Optionally, the stationary iron core 4 includes a first receiving cavity 47, which is located at one end of the stationary iron core 4 near the moving iron core 8. The first receiving cavity 47 is used to assemble the spring 6. By assembling the spring 6 in the first receiving cavity 47, the installation process of the spring 6 can be simplified. At the same time, the limiting structure of the first receiving cavity 47 prevents the spring 6 from shifting, thereby improving the assembly accuracy of the spring 6.

[0069] Optionally, the stationary iron core 4 further includes a first limiting portion 44, a second limiting portion 43, and a first connecting surface 42 fixedly connected to the housing 9. The first limiting portion 44 is recessed on the outer surface of the stationary iron core 4, and the second limiting portion 43 is protruding on the outer surface of the stationary iron core 4. The first limiting portion 44 and the second limiting portion 43 are snap-fitted into the housing 9 within the first receiving cavity 47 of the housing 9, ensuring that the stationary iron core 4 and the housing 9 can be fixed together. Simultaneously, the first connecting surface 42 contacts and engages with the sidewall of the first receiving cavity 47 at its outlet, extending outward along the housing 9, so that the fourth flow channel section 104 extends to the outside of the housing 9 and communicates with the flow channel of the application device.

[0070] Optionally, a first O-ring 3 is provided at the connection between the first limiting point 44 and the housing 9. The first O-ring 3 can ensure a sealed connection between the second limiting point 44 and the inner surface of the housing 9.

[0071] In some embodiments, the stationary iron core 4 includes:

[0072] Pressure relief hole 48, wherein the pressure relief hole 48 is disposed between the first receiving cavity 47 and the third flow channel section 103;

[0073] A first opening and closing element 49 is provided between the pressure relief hole 48 and the third flow channel section 103. The first opening and closing element 49 is used to control the opening and closing of the pressure relief hole 48 and the third flow channel section 103.

[0074] Optionally, the stationary iron core 4 also includes a pressure relief hole 48, which is disposed between the first receiving cavity 47 and the third flow channel section 103. A first opening and closing element 49 is provided between the pressure relief hole 48 and the third flow channel section 103, and the first opening and closing element 49 is used to control the opening and closing of the pressure relief hole 48 and the third flow channel section 103. Because fluid pressure may cause blockages in the flow channels within the stationary iron core 4 during fluid flow, a pressure relief hole 48 is installed inside the stationary iron core 4 near the third flow channel section 103. The pressure relief hole 48 and the third flow channel section 103 are connected by a first opening / closing element 49. When pressure builds up in the flow channels within the stationary iron core 4, causing fluid blockages, the pressure forces the first opening / closing element 49 open, connecting the pressure relief hole 48 to the third flow channel section 103. This allows the pressure of the fluid in the third flow channel section 103 to be released through the pressure relief hole 48, thus clearing the flow. After the fluid is cleared, as the flow channel pressure decreases, the first opening / closing element 49 closes, shutting off the connection between the pressure relief hole 48 and the third flow channel section 103. This method prevents the flow channel from becoming blocked due to abnormal pressure, thus improving the valve's operational safety.

[0075] In some embodiments, the moving iron core 8 includes:

[0076] The iron core body 84 has the first groove 81 provided on its outer surface.

[0077] Optional, such as Figure 2 As shown, the moving iron core 8 includes an iron core body 84, and a first groove 81 is provided on the outer surface of the iron core body 84. The first groove 81 on the outer surface of the iron core body 84 cooperates with the shell 9 to form a first flow channel section 101, thereby realizing the control of fluid flow.

[0078] In some embodiments, a rubber portion 82 is provided inside the iron core body 84, and a rubber protrusion 83 is formed on the side of the rubber portion 82 near the stationary iron core 4.

[0079] Optionally, a rubber section 82 is provided inside the iron core body 84, and a rubber protrusion 83 is formed on the side of the rubber section 82 near the stationary iron core 4. On the one hand, the rubber section 82 inside the iron core body 84 can reduce the weight of the moving iron core 8, which is beneficial to the lightweighting of the valve body, and at the same time, it can also ensure that the restoring force of the spring 6 is sufficient to drive the moving iron core 8 to move. On the other hand, the rubber protrusion 83 formed on the side of the rubber section 82 near the stationary iron core 4 can reduce the collision force between the moving iron core 8 and the stationary iron core 4 and reduce noise when the moving iron core 8 collides with the stationary iron core 4 due to the relative movement caused by the restoring force of the spring 6.

[0080] By using an integral vulcanization molding structure of the rubber part 82 and the metal core body 84, and adopting an integral vulcanization molding process at both ends, the connection strength between the rubber part 82 and the core body 84 can be improved, and the assembly steps between the rubber part 82 and the core body 84 can be reduced, thereby enhancing the assembly strength and stability.

[0081] In some embodiments, the iron core body 84 and the rubber part 82 are integrally formed.

[0082] Optionally, the iron core body 84 and the rubber part 82 are integrally molded. This integral molding process improves the connection strength between the rubber part 82 and the iron core body 84, reduces the number of assembly steps, and thus lowers the assembly difficulty.

[0083] In some embodiments, both the moving iron core 8 and the stationary iron core 4 are made of soft magnetic material.

[0084] Optionally, both the moving iron core 8 and the stationary iron core 4 are made of soft magnetic material. The soft magnetic material of the moving iron core 8 and the stationary iron core 4 can be magnetized in a magnetic field, so that the moving iron core 8 and the stationary iron core 4 can overcome the spring force of the return spring 6 and be attracted together under the action of magnetic force.

[0085] In some embodiments, the housing 9 includes:

[0086] Mounting part 96, the mounting part 96 includes the first receiving cavity 97, the first receiving cavity 97 is adapted to house the iron core 10;

[0087] The outer surface of the mounting part 96 is suitable for mounting a conductive coil 99.

[0088] Optional, such as Figure 5 As shown, the housing 9 includes a mounting portion 96, which includes a first receiving cavity 97 for mounting the iron core 10. A conductive coil 99 is also provided on the outer surface of the mounting portion 96. By mounting the stationary iron core 4 and the moving iron core 8 within the first receiving cavity 97 of the mounting portion 96, and then winding the conductive coil 99 around the outer surface of the mounting portion 96, a magnetic field is generated on the stationary iron core 4 and the moving iron core 8 after the conductive coil 99 is energized. This causes the stationary iron core 4 and the moving iron core 8 to generate an attractive force after magnetic transformation, overcoming the restoring force of the spring 6 and opening the first flow channel 100 inside the valve body and the external flow channel of the application device. This method allows for the integrated design of electromagnetic drive and valve body structure.

[0089] In some embodiments, the housing 9 includes:

[0090] A first connecting portion 91 includes a fifth flow channel 911, which is connected to the first flow channel segment 101.

[0091] Optionally, the housing 9 includes a first connecting portion 91, which includes a fifth flow channel 911 connected to a first flow channel segment 101. The first connecting portion 91 is paired with a fluid supply device, allowing the fifth flow channel 911 to connect with the flow channel of the fluid supply device. This fifth flow channel 911 connects the flow channel of the fluid supply device to the first flow channel segment 101, thus connecting the internal flow channels of the fluid supply device and the valve body, simplifying the design of the upper housing of the application device. The first connecting portion 91 is configured as a pagoda-shaped air source interface, which better matches the installation interface of the fluid supply device, achieving a good sealing effect.

[0092] In some embodiments, a second opening / closing member 95 is provided between the fifth flow channel 911 and the first flow channel segment 101, and the second opening / closing member 95 is used to control the opening and closing of the fifth flow channel 911 and the first flow channel segment 101.

[0093] Optionally, a second opening / closing element 95 is provided between the fifth flow channel 911 and the first flow channel section 101. The second opening / closing element 95 is used to control the opening and closing of the fifth flow channel 911 and the first flow channel section 101. In order to control the connection and closure of the flow channel 100 inside the valve body and the flow channel of the fluid supply device, a second opening / closing element 95 is provided between the fifth flow channel 911 and the first flow channel section 101. After the conductive coil 99 is energized, a magnetic force is generated in the first receiving cavity 97, and the stationary iron core 4 and the moving iron core 8 are magnetized. At this time, the stationary iron core 4 and the moving iron core 8 generate an attractive force after magnetic transformation to overcome the restoring force of the spring 6. The moving iron core 8 no longer exerts pressure on the second opening / closing element 95. After the fluid flows from the fifth flow channel 911, it generates an impact force on the second opening / closing element 95, thereby opening the second opening / closing element 95, so that the fifth flow channel 911 is connected to the first flow channel section 101, thereby enabling the valve body to start working. After the conductive coil 99 is switched on and off, the magnetic force in the first receiving cavity 97 disappears. After the stationary iron core 4 and the moving iron core 8 lose their magnetic force, the stationary iron core 4 and the moving iron core 8 are separated and returned to their original positions under the elastic force of the spring 6. At this time, the moving iron core 8 presses the second opening and closing element 95 to close the fifth flow channel 911 and the first flow channel section 101, so that the flow channel inside the valve body is no longer connected to the flow channel of the fluid supply equipment, and the valve body stops working.

[0094] In some embodiments, a boss 98 is provided between the mounting portion 96 and the first connecting portion 91;

[0095] The boss 98 is provided with a pin 93, which is adapted to connect to the conductive coil 99.

[0096] Optionally, a boss 98 is provided between the mounting part 96 and the first connecting part 91; the boss 98 is provided with a pin 93, which is connected to the conductive coil 99. The pin 93 is connected to a power source to conduct electricity to the conductive coil 99. By providing a pin 93 at the boss 98, the power supply to the conductive coil 99 is achieved, improving the overall structural compactness.

[0097] Optionally, the mounting part 96 also includes a positioning post 94 and a limiting hole 92. The positioning post 94 and the limiting hole 92 are both limiting structures for the housing 9 to be fixedly connected to the application equipment, so as to meet the different limiting requirements of the housing 9 and the application equipment.

[0098] In some embodiments, the first connecting portion 91, the boss 98, and the mounting portion 96 are integrally formed.

[0099] Optionally, the first connecting part 91, the boss 98, and the mounting part 96 are configured as an integrally formed structure. This solution reduces the number of parts in the valve body through an integral forming process, thereby improving the reliability of the valve body structure and assembly efficiency.

[0100] In some embodiments, the assembly structure 1 and the bracket 5 are assembled, the assembly structure 1 and the housing 9 are fixedly connected by the bracket 5, and the assembly structure 1 is adapted to connect to the application device.

[0101] Optionally, the valve body also includes an assembly structure 1 and a bracket 5. The assembly structure 1 is fixedly connected to the housing 9 via the bracket 5. The assembly structure 1 is adapted to be connected to the application equipment at the flow channel outlet of the valve body. By fixing the assembly structure 1 and the housing 9 via the bracket 5, stable assembly of the valve body and the application equipment is achieved, improving the overall integration.

[0102] In some embodiments, the assembly structure 1 includes:

[0103] The sixth flow channel 105 is connected to the fourth flow channel 104.

[0104] Optionally, the assembly structure 1 includes a sixth flow channel 105, which is connected to the fourth flow channel 104. By connecting the sixth flow channel 105 and the fourth flow channel 104, the flow channel of the application device is connected to the internal flow channel of the valve body, thereby optimizing the fluid flow path, reducing the intersection design between the internal flow channel of the valve body and the external flow channel of the application device, and improving the assembly integration of the valve body and the application device.

[0105] Optionally, the stationary iron core 4 also includes a third limiting point 41, which is located at the position where the first connecting surface 42 extends along the first receiving cavity 47, and is located outside the first receiving cavity 47 and connected to the assembly structure 1, so that the fourth flow channel section 104 communicates with the sixth flow channel 105. At the same time, the third limiting point 41 is fixedly connected to the assembly structure 1 by a snap-fit, and a second O-ring 2 is provided at the connection between the third limiting point 41 and the assembly structure 1, which can ensure a sealed connection between the third limiting point 41 and the assembly structure 1.

[0106] In some embodiments, the assembly structure 1 includes:

[0107] A sensor receiving cavity 13 is connected to the sixth flow channel 105. The sensor receiving cavity 13 is adapted to install a pressure sensor, which is adapted to monitor the pressure of the sixth flow channel 105.

[0108] Optional, such as Figure 7 As shown, the assembly structure 1 includes a sensor receiving cavity 13, which is connected to the sixth flow channel 105. The sensor receiving cavity 13 is suitable for installing a pressure sensor, which is suitable for monitoring the pressure of the sixth flow channel 105. By installing a pressure sensor in the sensor receiving cavity 13, real-time monitoring of the fluid pressure in the sixth flow channel 105 can be achieved. This allows for real-time reflection of the flow conditions within the valve body, timely adjustment of the fluid flow rate through the valve body, and prevention of flow channel blockage. Furthermore, the real-time monitoring of fluid pressure by the pressure sensor can improve the overall intelligence level of the valve body and enhance user comfort.

[0109] Optionally, the sensor housing cavity 13 is usually connected to the outer wall of the application device. Therefore, in order to ensure the sealing of the connection between the sensor housing cavity 13 and the outer wall of the application device, a housing sealing ring 14 is provided at the connection between the sensor housing cavity 13 and the outer wall of the application device.

[0110] Optionally, the assembly structure 1 also includes a mating interface 12 that connects the sixth flow channel 105 to the flow channel of the application device.

[0111] Optionally, the assembly structure 1 may also include a limiting hole 11 and a positioning post 15, both of which are fixed structures for assembling the assembly structure 1 with the application equipment.

[0112] Optionally, the fluid in this application can be a liquid fluid or a gaseous fluid, and there is no limitation herein.
