[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] The present invention provides a blowing and suction structure for ventilation of automobile seats, such as Figures 1 to 6 As shown, it includes: an air guide cover 1, and a ventilation component capable of blowing and sucking air is provided on one side of the air guide cover 1; The ventilation assembly includes: an interface 2, a pipe 3, a first channel 4 and a second channel 5 provided in the pipe 3, a bearing 6, a blower 7, a drive assembly for driving the pipe 3 to rotate, and a filter assembly provided at the second channel 5; The pipe 3 is rotatably connected to one side of the air guide cover 1 through a bearing 6 , and the interface 2 is rotatably installed on the other end of the pipe 3 through the bearing 6 . An air outlet 8 is provided on the blower 7 .

[0018] When in use, the interface 2 is connected to the seat air bag port, at this time the air inlet of the blower 7 is connected to the first channel 4, the blower 7 is started to suck air, and as the blower 7 sucks air, the outside air is filtered through the seat air bag and then discharged to the outside through the interface 2, the first channel 4, the air outlet 8, and the second channel 5, so that the suction work can be achieved. The blower 7 is turned off, and the duct 3 is driven by the driving component to rotate 180 degrees, so that the first channel 4 and the second channel 5 can be rotated, and finally the air inlet of the blower 7 is connected to the second channel 5. When the blower 7 is subsequently started to work, the outside air can be filtered through the filter component and then blown into the seat air bag through the second channel 5, the air outlet 8, the first channel 4, and the interface 2 for blowing. Finally, two ventilation effects can be achieved by a single blower 7, which brings a more comfortable feeling to people. When the temperature is high, the blowing mode can be turned on to cool down more quickly; when the temperature reaches a comfortable level, it can be adjusted to the suction mode, which makes people feel a more natural and comfortable temperature maintenance effect. The filter component can prevent dust from the outside air from entering the seat air bag, ensuring the cleanliness of the seat air bag and avoiding clogging of the seat air bag from the inside, which affects its use.

[0019] like Figures 1 to 4 As shown, the filter assembly includes: a frame 11, a filter frame 12, a filter 13, and a cleaning assembly for cleaning the filter 13; The frame 11 is fixedly installed inside the second channel 5 , the filter 13 is connected to the inside of the filter frame 12 , and the filter frame 12 is arranged inside the frame 11 .

[0020] When the pipe 3 rotates, the filter 13 can be cleaned by the cleaning component to keep it in a clean state so that it can filter normally. The dust in the outside air can be filtered by the filter 13 to prevent dust from entering the seat air bag.

[0021] like Figures 1 to 5 As shown, the cleaning assembly includes: a slider, a spring 14, an extrusion block 15, a shaft 16, an extrusion plate 17, a torsion spring 18, an arc surface 19 provided at the end of the extrusion plate 17, a stop rod 20, and a sealing assembly for closing the gap between the filter frame 12 and the frame 11; The slider is symmetrically fixed on the outside of the filter frame 12, and a slide groove corresponding to the slider is opened on the inner wall of the frame 11. The slider is slidably installed in the slide groove. The spring 14 fixes the side of the slider close to the pipe 3 to the inner wall of the slide groove. The extrusion block 15 is fixedly installed on the outside of the filter frame 12, and the shaft 16 is equidistantly fixed on the outside of the air guide cover 1. The extrusion plate 17 is rotatably sleeved on the outside of the shaft 16, and the torsion spring 18 is sleeved on the outside of the shaft 16. The two ends of the torsion spring 18 are respectively fixedly connected to the extrusion plate 17 and the shaft 16. The number of the baffle rod 20 corresponds to that of the extrusion plate 17. The baffle rod 20 is fixedly installed on the outside of the air guide cover 1, and the baffle rod 20 conflicts with one side of the extrusion plate 17. The extrusion block 15 is specifically a plate-shaped component with an inclined surface on one side, and the inclined surface can conflict with the arc surface 19.

[0022] When the duct 3 rotates and switches from the suction mode to the blowing mode, the duct 3 moves with the frame 11, the filter rack 12, the filter 13, and the extrusion block 15. After the extrusion block 15 conflicts with the extrusion plate 17, the extrusion block 15 pushes the extrusion plate 17 to rotate around the shaft 16, and the torsion spring 18 is twisted to deform it so that the extrusion plate 17 avoids the extrusion block 15. When the extrusion block 15 moves to separate from the extrusion plate 17, the torsion spring 18 resets and brings the extrusion plate 17 back to its original position. Subsequently, the extrusion block 15 conflicts with multiple extrusion plates 17 in sequence and separates. After the duct 3 rotates 180 degrees, it is now in the blowing mode. The sealing assembly seals the gap between the filter rack 12 and the frame 11. At this time, through the operation of the blower 7, the outside air is filtered through the filter 13 and finally discharged into the seat air bag for blowing. When it is necessary to switch to the suction mode, the duct 3 is rotated to reset. At this time, the sealing assembly cancels the seal of the gap between the filter frame 12 and the frame 11. Subsequently, when the extrusion block 15 contacts the arc surface 19 of the extrusion plate 17, the extrusion plate 17 cannot be deflected due to the interference of the blocking rod 20. The extrusion block 15 moves along the arc surface 19 in the direction close to the pipe 3, so that the filter frame 12 and the slider move accordingly to compress the spring 14 to deform it. When the extrusion block 15 leaves the extrusion plate 17, the spring 14 resets and the slider and the filter frame 12 quickly reset. At this time, the slider collides with the inner wall of the chute to generate vibration, which is transmitted to the filter 13, so that the dust on the surface thereof is shaken off. Subsequently, the extrusion block 15 contacts and separates from multiple extrusion plates 17, so that the filter 13 can be continuously vibrated, thereby cleaning the filter 13, keeping it clean, and enabling normal filtering work.

[0023] like Figure 3 As shown, the sealing assembly includes: a rubber strip 21, an air bag 22, a connecting tube 23, a fixing plate, and a pressing plate 24; A cavity is provided inside the rubber strip 21, and an embedding groove is opened on the inner wall of the frame 11 and in front of the slide groove. The rubber strip 21 is fixedly installed in the embedding groove, the fixing plate is fixedly installed on the outside of the frame 11, and the airbag 22 is fixedly installed on the outside of the fixing plate. The connecting pipe 23 connects the airbag 22 with the interior of the rubber strip 21, and the pressing plate 24 is fixedly installed on the outside of the driving assembly. When the airbag 22 is squeezed, the air inside it can be injected into the rubber strip 21 through the connecting pipe 23, causing the rubber strip 21 to expand. The expanded rubber strip 21 can close the gap between the filter frame 12 and the frame 11.

[0024] When the pipe 3 rotates to switch from the suction mode to the blowing mode, the frame 11 rotates accordingly, thereby moving the fixing plate and the airbag 22. Finally, when it is in the blowing mode, the airbag 22 is pressed against the pressing plate 24, and the air inside it is injected into the rubber strip 21 through the connecting tube 23, causing the rubber strip 21 to expand. The expanded rubber strip 21 can close the gap between the filter frame 12 and the frame 11, preventing outside air from entering the second channel 5 without being filtered. When the pipe 3 rotates to reset, the airbag 22 leaves the pressing plate 24 and returns to its original state. Conversely, the air can be drawn back, causing the rubber strip 21 to return to its original state and leave the filter frame 12. Subsequently, when the filter frame 12 vibrates, the rubber strip 21 can be prevented from obstructing it.

[0025] like Figure 1 As shown, the driving assembly includes: a motor 9, a gear 10, and teeth equidistantly arranged around the outside of the pipe 3; The motor 9 is fixedly mounted on the outside of the air guide cover 1 , the gear 10 is fixedly mounted on the outside of the output shaft of the motor 9 , the gear 10 is engaged with the teeth, and the pressing plate 24 is fixedly mounted on the outside of the motor 9 .

[0026] The motor 9 is started to rotate its output shaft, thereby causing the gear 10 to rotate, and the gear teeth cooperate with the pipe 3 to rotate, thereby driving the pipe 3.

[0027] like Figure 5 and Figure 6 As shown, when the pipeline 3 is in the initial state and when the pipeline 3 rotates 180 degrees, the interface 2 can maintain communication with the first channel 4.

[0028] The air inlet of the blower 7 is connected to the first channel 4 and the air inlet of the blower 7 is connected to the second channel 5. The blower 7 is started to suck air. As the blower 7 sucks air, the outside air is filtered through the seat air bag and then discharged to the outside through the interface 2, the first channel 4, the air outlet 8 and the second channel 5, so that the suction work can be realized. The blower 7 is turned off and the duct 3 is driven by the driving component to rotate 180 degrees, so that the first channel 4 and the second channel 5 can be rotated. Finally, the air inlet of the blower 7 is connected to the second channel 5. When the blower 7 is subsequently started to work, the outside air can be filtered through the filter 13 and then blown into the seat air bag through the second channel 5, the air outlet 8, the first channel 4 and the interface 2 for blowing. Finally, a single blower 7 can achieve two ventilation effects, giving people a more comfortable feeling. When the temperature is high, the blowing mode can be turned on to cool down more quickly. When the temperature reaches a comfortable level, it can be adjusted to the suction mode, which makes people feel a more natural and comfortable temperature maintenance effect. When the pipe 3 rotates and switches from the suction mode to the blowing mode, the pipe 3 moves with the frame 11, the filter rack 12, the filter screen 13, and the squeeze block 15. After the squeeze block 15 conflicts with the squeeze plate 17, the squeeze block 15 pushes the squeeze plate 17 to rotate around the shaft 16, and the torsion spring 18 is twisted to deform it, so that the squeeze plate 17 avoids the squeeze block 15. When the squeeze block 15 moves to separate from the squeeze plate 17, the torsion spring 18 resets and brings the squeeze plate 17 back to its original position. Subsequently, the squeeze block 15 conflicts with multiple squeeze plates 17 in sequence and separates. After the pipe 3 rotates 180 degrees, it is now in the blowing mode. In the wind mode, when the pipe 3 rotates and switches from the suction mode to the blowing mode, the frame 11 rotates accordingly, thereby moving the fixing plate and the air bag 22 accordingly. Finally, when it is in the blowing mode, the air bag 22 is pressed against the pressing plate 24, and the air inside it is injected into the rubber strip 21 through the connecting pipe 23, so that the rubber strip 21 expands. The expanded rubber strip 21 can close the gap between the filter frame 12 and the frame 11, preventing the outside air from entering the second channel 5 without being filtered. When blowing subsequently, the outside air can be filtered through the filter 13. The dust in the seat is filtered, and the outside air is filtered through the filter 13 and finally discharged into the seat air bag to prevent dust from entering the seat air bag and realize blowing. When it is necessary to switch to the suction mode, the pipe 3 is rotated and reset, and the air bag 22 leaves the pressing plate 24, and the air bag 22 returns to its original state. On the contrary, the air can be drawn back, so that the rubber strip 21 returns to its original state and leaves the filter frame 12. Then, when the extrusion block 15 conflicts with the arc surface 19 of the extrusion plate 17, the extrusion plate 17 cannot be deflected due to the conflict of the stop rod 20, and the extrusion block 15 moves along the arc surface 1 9 moves in the direction close to the pipe 3, so that the filter frame 12 and the slider move accordingly to compress the spring 14 to deform it. When the extrusion block 15 leaves the extrusion plate 17, the spring 14 resets and the slider and the filter frame 12 quickly reset. At this time, the slider collides with the inner wall of the chute to generate vibration, which is transmitted to the filter 13, so that the dust on its surface is shaken off. Subsequently, the extrusion block 15 is separated from the multiple extrusion plates 17, so that the filter 13 can be continuously vibrated, thereby cleaning the filter 13, keeping it clean, and able to perform normal filtering work.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
