DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the implementation mode of the present application clearer, the technical solution in the implementation mode of the present application will be clearly and completely described in combination with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is a part of the implementation mode of the present application, not all the implementation modes. Based on the implementation mode in the present application, all other implementation modes obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. The specific implementation modes of the present invention are described in detail in combination with the drawings in the specification.

[0034] When sitting on a seat for a long time, the contact surface between the human body and the seat is prone to feel stuffy and uncomfortable due to lack of air circulation, and may even cause sweating and skin discomfort. The ventilation system introduces or exhausts air to keep the seat surface dry, providing a more comfortable riding environment for the driver and passengers. The role of the ventilation system is particularly obvious in hot weather or long-term driving, which can improve riding comfort and satisfaction.

[0035] The suction device in the ventilation system can achieve effective ventilation inside the seat. The suction device can suck air from the outside of the seat to the inside, forming air flow, thereby ensuring that the air inside the seat can circulate smoothly. It can not only quickly take away the heat and moisture on the surface of the seat, but also reduce the moisture and odor inside the seat, keeping the seat clean and comfortable.

[0036] However, in actual operation, when the suction device starts and sucks air, external dust is easily brought into the seat back with the airflow. When the suction device stops working, due to inertia or static electricity, dust particles will adhere to the surface of the suction fan blades. The dust attached to the suction fan blades will gradually accumulate to form a thick dust layer. The accumulation of the dust layer will increase the friction resistance of the suction fan blades during rotation, causing the suction device to consume more energy to overcome this resistance. It will also block the rotation of the fan blades and reduce the suction force of the suction device, thereby affecting the overall ventilation efficiency of the seat ventilation system, which will cause poor air circulation inside the seat, and cannot effectively remove moisture and sweat from the seat surface, reducing riding comfort.

[0037] The present application proposes an air suction device for a seat ventilation system, which can seal the ventilation holes of the air suction component 2 to prevent dust from adhering to the surface of the fan blades 201 in the air suction component 2 after the air suction component 2 stops working, thereby increasing the burden on the rotation of the fan blades 201 and causing problems such as increased energy consumption and reduced ventilation efficiency of the air suction device.

[0052] Embodiment 4: This embodiment provides an air suction device for a seat ventilation system, which further includes the following structure based on the embodiment 3:

[0053] like Figure 1 , Figure 2 and Figure 11-13 As shown, a filter assembly 4 is installed on the top of the driving assembly 3;

[0054] The filter assembly 4 includes a filter cartridge 401, the top of the filter cartridge 401 is detachably connected to the support sleeve 301, the inner wall of the filter cartridge 401 is sleeved with a connecting plate 402, the inner wall of the connecting plate 402 is fixedly connected to a second mounting sleeve 406, the inner wall of the second mounting sleeve 406 is fixedly connected to a convex block 407, the inner wall of the second mounting sleeve 406 is slidably connected to a convex rod 408, the outer wall of the convex rod 408 is provided with a cam groove 409, and the cam groove 409 is slidably connected to the convex block 407;

[0056] The cleaning brush 403 cleans the dust in the mesh of the filter cartridge 401, preventing dust accumulation and reducing equipment failures caused by dust; the use of the cleaning brush 403 in conjunction with the micro cylinder 404 not only improves the cleaning efficiency, but also ensures the continuous unobstructed mesh of the filter cartridge 401, preventing dust clogging.

[0057] Working principle: The two motors 303 drive the driving shaft 304 to rotate respectively, the driving shaft 304 drives the third bevel gear 306 to rotate, the third bevel gear 306 drives the fourth bevel gear 308 to rotate, and the fourth bevel gear 308 drives the third connecting shaft 307 to rotate;

[0058] The fixed shaft 202 is driven to rotate by the third connecting shaft 307, and the push plate 220 is driven to rotate by the fixed shaft 202. The push plate 220 squeezes the external plate 212, and the external plate 212 drives the docking shaft 210 to rotate through the limit plate 211. When the external plate 212 is blocked by the baffle 216, the push plate 220 drives the second rotating shaft 219 to rotate until the push plate 220 flips into the mounting hole 218. The mounting hole 218 is sealed by the push plate 220, so that a relatively complete surface is formed on the top of the mounting seat 217. When the fixed shaft 202 rotates quickly, the roller 214 rolls along the complete surface of the top of the mounting seat 217, thereby reducing wear between the structures.

[0060] When the fixed shaft 202 rotates, it can drive the fan blades 201 to rotate to produce a suction effect, and filter the dust in the airflow through the filter cartridge 401;

[0061] When the third connecting shaft 307 rotates, it can drive the convex rod 408 to rotate.

When the connecting plate 402 moves, it can drive the cleaning brush 403 to rub and contact along the inner wall of the filter cartridge 401, so as to clean the dust in the mesh of the filter cartridge 401.

[0062] The connecting plate 405 is driven to move by the simultaneous extension and contraction of the multiple micro cylinders 404, and the cleaning brush 403 is driven to move up and down a short distance quickly through the connecting plate 405. When the bristles on the cleaning brush 403 move upward, the bristles are squeezed by the filter cartridge 401 and bend downward. When the cleaning brush 403 moves downward quickly, the bent ends of the bristles can be more easily inserted into the mesh of the filter cartridge 401, so that the dust blocked in the mesh of the filter cartridge 401 can be cleaned;

[0063] By rotating the multiple adjusting screws 311, the clamping plates 310 are respectively disengaged from the clamping connection with the adjusting gear ring 309, and the position of the motor 303 can be adjusted by rotating the supporting ring 302, so that the installation direction of the motor 303 can be adjusted, so that the motor 303 can be rotated to a position convenient for heat dissipation for installation;

[0064] After the fan blade 201 stops, the motor 303 drives the third connecting shaft 307 to rotate in the opposite direction, the third connecting shaft 307 drives the mounting seat 217 to rotate in the opposite direction, and the mounting seat 217 drives the push plate 220 to rotate in the opposite direction. At this time, the push plate 220 passes through the reserved hole 223 on the baffle 216, and the push plate 220 squeezes the external plate 212 in the opposite direction. The push plate 220 is blocked by the mounting hole 218. At this time, the docking shaft 210 can rotate in the opposite direction, so that the multiple partition fans 102 are closed and the top of the first mounting sleeve 101 is sealed.
