[0033] The valve body air intake structure 1 according to an embodiment of the utility model is described below with reference to the accompanying drawings.

[0034] like Figure 1-Figure 5 As shown, the valve body air intake structure 1 according to the embodiment of the utility model includes an air intake connector 100 and a filter 200 .

[0035] The air intake connector 100 is suitable for being plugged into the air intake valve port 10. The filter screen 200 is installed in the air intake valve port 10, and the filter screen 200 has a large diameter end 201 and a small diameter end 202, the large diameter end 201 is adjacent to the outer side of the air intake valve port 10, the small diameter end 202 is adjacent to the inner side of the air intake valve port 10, the centers of the large diameter end 201 and the small diameter end 202 are connected to each other, the peripheries of the large diameter end 201 and the small diameter end 202 are connected to each other and are configured with filter holes 203, and the air intake connector 100 stops at the outer side of the large diameter end 201 of the filter screen 200.

[0036] For example, during the assembly process of the valve body air intake structure 1 of this embodiment, the filter 200 is first installed in the air intake valve port 10, and then the air intake connector 100 is pushed axially along the valve port until it stops at the outside of the large diameter end 201 of the filter 200 to ensure that the position of the air intake connector 100 and the filter 200 are accurately docked.

[0037] According to the valve body air intake structure 1 of the embodiment of the utility model, the filter 200 is divided into a large diameter end 201 and a small diameter end 202, the large diameter end 201 is adjacent to the outer side of the air intake valve port 10, and the small diameter end 202 is adjacent to the inner side of the air intake valve port 10. By utilizing the aperture difference between the large diameter end 201 and the small diameter end 202 of the filter 200, the large diameter end 201 can allow gas to pass through, forming an air flow channel between the large diameter end 201 and the small diameter end 202, and when impurities pass through the filter 200 between the large diameter end 201 and the small diameter end 202, they are filtered out by the filter holes 203 of the filter 200, thereby ensuring the cleanliness of the gas, preventing excessive impurities from entering the air intake joint 100, affecting the normal use of the brake valve, and improving the service life of the overall structure. At the same time, filter holes are constructed on the periphery between the large diameter end 201 and the small diameter end 202. Such a structure can ensure that the flow of gas is not hindered, and the gas passes through the filter holes 203 radially outward along the filter screen 200. The filter holes 204 cover a larger area on the outer peripheral surface of the filter screen 200, which can provide more sufficient filtration, effectively filter out larger impurities, and improve the reliability and stability of the overall structure.

[0038] Therefore, the valve body air intake structure according to the embodiment of the utility model improves the reliability of the overall structure by effectively filtering larger impurities.

[0039] In some specific embodiments of the present invention, Figure 5 As shown, the filter 200 includes a filter mounting portion 210 and a truncated cone portion 220. The filter mounting portion 210 is formed at the large diameter end 201, the filter mounting portion 210 is installed in the air intake valve port 10, and the air intake connector 100 stops at the outside of the filter mounting portion 210. The truncated cone portion 220 is connected to the side of the filter mounting portion 210 facing the air intake valve port 10, and the filter holes 203 are formed in the truncated cone portion 220. For example, the minimum diameter of the filter mounting portion 210 is greater than the maximum diameter of the truncated cone portion 220, and the minimum diameter end of the truncated cone portion 220 is smaller than the diameter at the air intake valve port 1, and the filter holes 203 are evenly arranged along the circumference of the truncated cone portion 220. By installing the filter mounting portion 210 in the air intake valve port 10, the filter can be fixed, effectively preventing the filter 200 from moving or falling off, and ensuring the purification effect of the filter 200 during the air intake process. The air intake connector 100 stops at the outside of the filter installation part 210, which can play an additional role in fixing the filter, ensuring the stability and accuracy of the position of the filter 200, and avoiding looseness or interference between the air intake connector 100 and the filter 200. The filter hole 203 formed by the truncated cone part 220 can provide a more uniform and stable airflow for the intake, and at the same time, the filter hole 203 can filter and purify the air, thereby ensuring the quality of the air entering the car engine.

[0040] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, a step portion 11 with a reduced diameter is constructed inside the air intake valve port 10, and the filter screen mounting portion 210 is constructed with an outer flange 211 that matches the step portion 11. The diameter at the step portion 11 is substantially the same as the diameter of the structure of the filter screen mounting portion 210 adjacent to the outer flange 211, and the diameter of the outer flange 211 is larger than the diameter at the step portion 11 and slightly smaller than the diameter of the interface adjacent to the air intake valve port 10. By limiting the outer flange 211 and the step portion 11, the relative fixation of the position of the filter screen mounting portion 210 and the air intake valve port 10 is ensured, the filter screen 200 is prevented from loosening or falling off, the normal operation of the filter screen 200 is ensured, foreign matter or dust is effectively prevented from entering the valve body, the valve body is protected from contamination by impurities, and the service life is extended.

[0041] In some specific embodiments of the present invention, Figure 5 As shown, the inner diameter of the side of the filter mounting portion 210 adjacent to the truncated cone portion 220 is larger than the maximum inner diameter of the truncated cone portion 220, and the filter mounting portion 210 is suitable for accommodating the intake connector 100. The inner diameter of the filter mounting portion 210 is larger than the maximum inner diameter of the truncated cone portion 220, which can provide sufficient installation space for the intake connector 100, ensuring that the intake connector 100 can be easily and firmly installed in the filter mounting portion 210, avoiding difficulties and instability during the installation process. Since the filter mounting portion 210 is suitable for accommodating the intake connector, it can ensure that the connection between the intake connector 100 and the filter 200 is tight and stable, avoiding airflow leakage or abnormal intake caused by loose joints or poor connections, and improving the operating efficiency and performance of the engine.

[0042] In some specific embodiments of the present invention, Figure 5 As shown, the outer diameter of the filter mounting portion 210 on one side adjacent to the truncated cone portion 220 gradually decreases in the direction of the truncated cone portion 220. The gradual reduction of the outer radial truncated cone portion 220 can adapt to the structural space requirements and ensure that the connection between the filter mounting portion 210 and the truncated cone portion 220 is compact and effective. Such a structure helps to achieve a stable installation of the filter 200 in a limited space and ensure the normal operation of the intake system. At the same time, the design of gradually decreasing outer diameter helps to increase the smoothness and uniformity of the air streamline during the intake process and reduce the turbulence and resistance of the airflow. This can improve the efficiency and stability of the airflow and promote the performance of the engine.

[0043] In some specific embodiments of the present invention, Figure 1 and Figure 2As shown, the air intake connector 100 includes a nut seat 110 and a quick-connect connector 120. The nut seat 110 is configured with an external thread, and the inner peripheral wall of the air intake valve port 10 is configured with an internal thread, and the nut seat 110 is screwed to the air intake valve port 10. The quick-connect connector 120 is plugged into the nut seat 110. During the assembly process of the valve body air intake structure 1, the filter screen 200 is first fixed inside the air intake valve port 10, and then the nut seat 110 is screwed to the large diameter end 201 of the filter screen 200, and finally the quick-connect connector 120 is passed through the nut seat 110 and fixed inside the filter screen 200.

[0044] The nut seat 110 can be fastened to the intake valve port 10 by screwing, ensuring that the nut seat 110 and the intake valve port 10 are tightly connected and firmly fixed to avoid airflow leakage or safety hazards caused by looseness. The quick-plug connector 120 is plugged into the nut seat 110 and connected to the nut seat by a simple plug-in and pull-out method. This structure facilitates the rapid installation and replacement of the intake system, improves the convenience of maintenance and operation, and can ensure the stable connection and reliability of the intake connector 100, avoid loosening or falling off during use, and ensure the normal operation and safety of the intake system.

[0045] In some specific embodiments of the present invention, Figure 4 As shown, the nut seat 110 has a nut 111, which stops at the outside of the intake valve port 10, and an outer sealing ring 12 is constructed between the nut 111 and the intake valve port 10. The nut 11 stops at the outside of the intake valve port 10, and the sealing between the intake valve port 10 and the nut 111 can be effectively improved through the structure of the outer sealing ring 12. The existence of the outer sealing ring 12 can prevent gas or liquid from leaking from the connection, ensuring the sealing and working stability of the intake system.

[0046] The nut 111 stops at the outside of the intake valve port 10, and can also play a role in fixing the nut seat 110 to prevent the nut 111 from loosening or falling off during use. Such a structure can improve the stability and reliability of the connection and reduce problems caused by loose parts.

[0047] In some specific embodiments of the present invention, Figure 1-Figure 4As shown, the air intake connector 100 also includes a retaining spring 130. The retaining spring 130 clamps the quick-connect connector 120 and stops at the inner side of the nut seat 110 in the air intake valve port 10. The retaining spring 130 ensures that the connection between the quick-connect connector 120 and the nut seat 110 is tight and stable by clamping the quick-connect connector 120. This helps prevent the quick-connect connector 120 from loosening or falling off due to vibration or other factors during use, thereby improving the reliability of the entire air intake system. At the same time, the retaining spring 130 stops at the inner side of the nut seat 110 in the air intake valve port 10, which can effectively limit the movement range of the quick-connect connector 120, ensure its stable position, help prevent the quick-connect connector 120 from being misplaced or falling off, ensure the normal operation of the system, and improve the safety of the entire system.

[0048] In some specific embodiments of the present invention, Figure 3 As shown, the valve body air intake structure 1 further includes an inner seal 300. The inner seal 300 is disposed on one side of the quick connector 120 facing the air intake valve port 10, and the inner seal 300 is sealed between the filter mounting portion 210 and the quick connector 120 in both the axial and radial directions.

[0049] The inner seal 300 can effectively achieve the seal between the filter installation part 210 and the quick connector 120 to prevent gas or liquid leakage. The axial and radial sealing design of the inner seal 300 can ensure a more reliable and stable sealing effect. As a sealing component, the inner seal can prevent dust, impurities and other external substances from entering the air inlet connector, play a role in protecting the quick connector 120 and the filter installation part 210, help to extend the service life of parts, and reduce the frequency of maintenance and replacement.
