[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Depend on Figures 1-8 As shown, the present invention includes a housing 1, an air inlet 11 is provided at the top of the housing 1, an air outlet 12 is provided on one side surface of the housing 1, and a fan is installed inside the housing 1 on one side of the air outlet 12. Air inside the car can be drawn into the housing 1 through the air inlet 11, filtered, and then discharged through the air outlet 12 in conjunction with the fan.

[0028] For example, the top and side walls of the housing 1 are both fixed with cover plates by bolts. A filter screen 16 is rotatably installed inside the housing 1. A filter cloth 23 is rotatably installed inside the housing 1 above the filter screen 16. After the outside air enters the housing 1, the air is filtered for the first time by the filter cloth 23 and then filtered for the second time by the filter screen 16, so as to facilitate the filtration of impurities in the air.

[0029] For example, a winding mechanism 2 for winding up the filter cloth 23 is rotatably installed inside the housing 1. When the filter cloth 23 has been used for filtering for a long time, dirt will be generated on its surface. The used filter cloth 23 is wound up by the winding mechanism 2. Under the action of the winding mechanism 2, the unused clean filter cloth 23 can be turned out from the winding roller 22, so as to facilitate the continued use of filtering air entering the housing 1.

[0030] For example, a locking mechanism 3 extending into the interior of the housing 1 is rotatably mounted on the surface of the housing 1, and the locking mechanism 3 can lock and rewind the winding mechanism 2. By using the locking mechanism 3, the winding mechanism 2 can be locked, thereby facilitating the positioning of the filter cloth 23 and preventing the filter cloth 23 from moving during the vehicle's operation. At the same time, the locking mechanism 3 can drive the winding mechanism 2 to rotate, thereby facilitating the rewinding and replacement of the used filter cloth 23.

[0031] For example, the winding mechanism 2 includes a winding roller 21 and a winding roller 22 rotatably mounted on the inner wall of the housing 1. The filter cloth 23 is wound around the outer wall of the winding roller 21 and the winding roller 22. The winding roller 21 can be used to wind up the used filter cloth 23, and the winding roller 22 can be used to store the unused filter cloth 23. The filter cloth 23 is adhered to the outer wall of the winding roller 21 and the winding roller 22 with glue.

[0032] Please see Figure 6 , Figure 7 , Figure 8 The locking mechanism 3 includes a transmission block 32 rotatably connected to the surface of the housing 1. One end of the transmission block 32 extends into the interior of the housing 1 and is symmetrically fixedly connected with two sets of insert rods 322. One end of the take-up roller 21 is provided with two sets of slots 211 that match the insert rods 322. The end of the transmission block 32 away from the insert rods 322 is located outside the housing 1 and is rotatably fitted with a knob 31. Two sets of locking blocks 321 are symmetrically fixedly connected to the outer wall of the transmission block 32. The inner side of the knob 31 is provided with a slot 312 that matches the locking block 321. By inserting the insert rods 322 into the inner wall of the slots 211 and then applying a clockwise rotation force to the knob 31, the take-up roller 21 can be driven to rotate through the transmission block 32 and the insert rods 322, thereby facilitating the winding and replacement of the used filter cloth 23.

[0033] Please see Figure 6, Figure 7 , Figure 8 A return spring 33 is fixedly connected to the center of the inner wall of the slot 312. Multiple sets of toothed grooves 311 are opened at one end of the knob 31. Multiple sets of teeth 34 that match the toothed grooves 311 are fixedly connected to the surface of the housing 1. When it is necessary to drive the winding roller 21 to rotate through the transmission block 32, the toothed grooves 311 and teeth 34 on the knob 31 are separated by pulling the knob 31. The transmission block 32 can be driven to rotate by the mutual cooperation of the slot 312 and the locking block 321. The knob 31 rotates and the used filter cloth 23 is completely rolled up onto the winding roller 21, which facilitates the winding and replacement of the filter cloth 23. After the replacement is completed, the knob 31 is released and the knob 31 is reset under the force of the return spring 33. At this time, the teeth 34 are engaged with the toothed grooves 311 of the knob 31, which facilitates the locking of the knob 31.

[0034] Please see Figure 1 , Figure 2 , Figure 3 An air supply hood 15 is fixedly connected to the top of the inner wall of the housing 1 at the contact position with the air inlet 11. A sponge pad is fixedly connected to the bottom of the air supply hood 15. By setting the air supply hood 15, the air entering the housing 1 from the air inlet 11 can be directly filtered through the filter cloth 23, which improves the filtration effect of the filter cloth 23 to a certain extent.

[0035] For example, two sets of baffles 13 are symmetrically fixedly connected to both ends of the air supply hood 15 on the inner wall of the housing 1. Sponge blocks 14 are fixedly installed at the contact positions between the two sets of baffles 13 and the filter cotton cloth 23. The baffles 13 and sponge blocks 14 can shield other structures inside the housing 1, thereby preventing air containing impurities from contaminating the clean filter cotton cloth 23.

[0036] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 Guide rollers 24 are fixedly connected to the inner wall of the housing 1 on the side of the two sets of baffles 13 away from the air supply hood 15. A movable roller 25 is rotatably connected to the side of the guide roller 24 near the winding roller 22. The height of the movable roller 25 is lower than the height of the winding roller 22 and the guide roller 24. The arrangement of the two sets of guide rollers 24 facilitates the parallel movement of the filter cloth 23 inside the housing 1, and at the same time makes the filter cloth 23 in close contact with the air supply hood 15, improving the filtration effect. The movable roller 25 can straighten the filter cloth 23, thereby preventing the filter cloth 23 from becoming loose inside the housing 1, which improves the filtration effect of the filter cloth 23 to a certain extent.

[0037] Please see Figure 5One end of the winding roller 22 is fixedly connected to a first gear 26, and a second gear 27 meshes below the first gear 26. The second gear 27 is rotatably mounted on the inner wall of the housing 1. The second gear 27 is designed to have a certain rotational resistance. The mutual cooperation between the first gear 26 and the second gear 27 increases the resistance to the rotation of the winding roller 22, preventing the winding roller 21 from winding too much at once, which would result in the waste of the filter cloth 23.

[0038] Please see Figure 1 and Figure 8 An opening is provided on the surface of the housing 1 at the position corresponding to the filter cloth 23, and a glass window 17 is fixedly installed on the inner wall of the opening. The use of the filter cloth 23 can be viewed through the glass window 17, so as to facilitate timely winding and replacement of the filter cloth 23.

[0039] Working principle: When replacing the filter cloth 23, after installing the roll roller 22 and the take-up roller 21, the first gear 26 and the second gear 27 are meshed. The filter cloth 23 is wound around the bottom of the movable roller 25 and in contact with the outer wall of the movable roller 25. The filter cloth 23 is then passed through the two sets of sponge blocks 14 and in contact with the upper outer wall of the guide roller 24. The filter cloth 23 can then be used.

[0040] Furthermore, after the filter cloth 23 has been filtering for a long time, pulling the knob 31 separates the groove 311 and teeth 34 on the knob 31. Rotating the knob 31 then drives the transmission block 32 to rotate under the cooperation of the locking block 321 and the locking slot 312. The transmission block 32, through the cooperation of the insert rod 322 and the slot 211, drives the take-up roller 21 to rotate, thus facilitating the take-up of the dirty filter cloth 23. The take-up roller 22, under the action of the take-up roller 21, then winds up the clean filter cloth 23. When the filter cloth 23 is rotated out, the air can be filtered through the filter cloth 23, reducing the number of times the filter cloth 23 needs to be replaced. After the filter cloth 23 is used up, the knob 31 is released. The knob 31 is reset by the action of the return spring 33. The groove 311 and the tooth 34 mesh, thereby locking the knob 31 and preventing the knob 31 from rotating due to external bumps during the car's operation. When the filter cloth 23 on the roll roller 22 is used up, the filter cloth 23 can be replaced.
