[0026] It should be noted that the distribution box assembly 1 and the air inlet assembly 11 are fastened together by screws to facilitate the subsequent disassembly and maintenance of the device, thereby avoiding replacement of the entire device as soon as a problem occurs and avoiding unnecessary losses.

[0027] In an optional embodiment, two ends of the L-shaped scraper 33 are in contact with the first filter 31 and the second filter 32 respectively, and a first groove is provided on the L-shaped scraper 33 .

[0028] It should be noted that the L-shaped scraper 33 cleans the impurities on the first filter 31 and the second filter 32 during use, so as to prevent the impurities generated in the device from flowing out from the blowing air outlet 18 into the vehicle and polluting the internal environment of the vehicle.

[0029] In an optional embodiment, a sliding track is provided on the limiting disk 22 , and the size of the sliding track is adapted to the first filter 31 .

[0030] It should be noted that when the driver slides the first rotator 21 , the first filter 31 does not move following the movement of the limiting plate 22 , but the second filter 32 slides following the sliding of the first rotator 21 , thereby cleaning the impurities on the second filter 32 .

[0034] It should be noted that when the first wind shield 251 and the second wind shield 261 are completely overlapped, it is ensured that wind cannot pass through. By rotating the first rotator 21 to drive the second wind shield 261 to rotate, the overlapping part of the second wind shield 261 and the first wind shield 251 is controlled, so as to control the air outlet in the face-blowing air outlet 18.

[0039] In an alternative embodiment, the control plate 24 is sized to fit within the inner diameter of the restrictor disk 22 .

[0041] In an optional embodiment, the first rotator 21 is slidably connected to the fixed disk 25 , the fixed disk 25 is confined inside the first rotator 21 , and the connecting rod 26 is fixedly connected to the first rotator 21 .

[0042] It should be noted that the fixing plate 25 is restricted inside the connecting rod 26 to ensure the fit between the first wind shield 251 and the second wind shield 261, and no gap will appear during operation to affect the air outlet.

[0043] Working principle: When using this device, install the device on the car, turn on the blower 12 to introduce air into the device through the external circulation air inlet 112 and the internal and external circulation damper plate 113, cool the gas through the refrigeration device 15, heat the gas through the heating device 14, and discharge the cooled or heated gas through the face-blowing air vents 18 and the defrost air vents 19 to achieve heating or cooling in the car. At the same time, when the gas is discharged through the face-blowing air vents 18, the driver manually rotates the first rotator 21, and the rotation of the first rotator 21 drives the connecting rod 26 to rotate, and the rotation of the connecting rod 26 drives the second wind deflector 261 to rotate. The first rotator 21 is rotated to adjust the overlapping position of the second wind deflector 261 and the first wind deflector 251 to control the cross-sectional area of ​​the fixed plate 25 through which the wind can pass, thereby controlling the air output through the face-blowing air vents 18.

[0044] At the same time, when the first rotator 21 is rotated, the limiting disk 22 is driven to rotate. The rotation of the limiting disk 22 drives the control panel 24 to rotate, so as to adjust the direction of the wind on the face air outlet 18. At the same time, the driver rotates the rotator 23, driving the control panel 24 to rotate around the rotating roller 231, so as to control the direction and angle of the wind outlet 18, which is more convenient for the driver to use and provides a better posture environment.

[0045] At the same time, when in use, the first filter 31 is rotated, the first filter 31 rotates in the groove on the limiting disk 22, and the L-shaped scraper 33 scrapes the impurities on the first filter 31. At the same time, the scraped impurities slide through the groove inside the L-shaped scraper 33 and are stored in the ash storage bin 34. At the same time, when the first rotator 21 is rotated, the limiting disk 22 is driven to rotate, and the rotation of the limiting disk 22 drives the ash storage bin 34 to rotate. When the ash storage bin 34 rotates, the L-shaped scraper 33 scrapes the impurities inside the second filter 32, and also flows into the ash storage bin 34 through the groove on the L-shaped scraper 33, so as to ensure that the impurities scraped on the L-shaped scraper 33 all enter the ash storage bin 34. When the air conditioner is not in use, the first filter 31 can be disassembled, and the impurities in the ash storage bin 34 can be cleaned up, which is convenient for subsequent continued use.

[0046] The distribution box assembly 1 and the air inlet assembly 11 are fastened together by screws to facilitate subsequent disassembly and maintenance of the device, so as to avoid replacement of the entire device as soon as a problem occurs, thereby avoiding unnecessary losses. The L-shaped scraper 33 cleans impurities on the first filter 31 and the second filter 32 during use, so as to prevent impurities generated in the device from flowing out from the blowing air outlet 18 into the interior of the vehicle and polluting the internal environment of the vehicle. When the driver slides the first rotator 21, the first filter 31 does not move with the movement of the limiting disk 22, but the second filter 32 slides with the sliding of the first rotator 21, thereby cleaning impurities on the second filter 32. The ash storage bin 34 is set on the limiting disk 22 and rotates with the rotation of the first rotator 21, so as to ensure that the ash storage bin 34 can always collect impurities inside the first filter 31 and the second filter 32, thereby ensuring the filtering effect of the device and avoiding long-term operation. The filtering effect of the device is affected. When the first wind shield 251 and the second wind shield 261 are completely overlapped, it is ensured that no wind can pass through. The second wind shield 261 is driven to rotate by rotating the first rotator 21 to control the overlapping part of the second wind shield 261 and the first wind shield 251, so as to control the air outlet in the face-blowing air outlet 18. The air intake of the internal circulation air inlet 111 and the external circulation air inlet 112 is controlled by the internal and external circulation damper plates 113. When the internal circulation compensation air outlet is used, the internal and external circulation damper plates 113 are controlled to adjust the external air intake to avoid noise caused by long-term use of the blower 12. By plugging the limiting barrel 252 and the limiting column 262, it is ensured that there is no gap between the first wind shield 251 and the second wind shield 261 and no air leakage, thereby ensuring the effect of the device. The fixed plate 25 is limited inside the connecting rod 26 to ensure the fit between the first wind shield 251 and the second wind shield 261, and no gap will appear to affect the air outlet during operation.
