[0002] As car air conditioners become more and more energy-efficient, turning on the air conditioner in the car has become a must, whether in summer or winter. Especially in winter, if the air conditioner is not turned on in the car, it is easy for the front windshield to fog up, affecting driving. Due to the small space in the car, turning on the air conditioner for a long time in the car will make the air in the car turbid, causing the harmful micro-objects in the car to exceed the standard, thus affecting the health of the people in the car. Turning on the air conditioner for a long time will make the air in the car dry, which is easy to cause people to suffer from respiratory diseases.

[0035] Further, combined with Figure 3 , Figure 6 The cleaning mechanism 90 includes a telescopic rod 19 located inside a second atomizing nozzle 46 fixedly arranged at the cleaning device. A soft water pipe 18 is fixedly arranged at the end of the second atomizing nozzle 46 away from the cleaning device. The other end of the soft water pipe 18 passes through the cleaning cover 10 and opens toward the base 21 side. The water chamber 24 is connected to the soft water pipe 18 through a cleaning pipe 39 away from the piston plate 33.

[0036] Working principle: first add water or liquid air freshener into the water cavity 24, fix the base 21 to a certain place in the car away from the side of the cleaning space 11, start the motor 26, and make the motor 26 drive the turbine rod 29 to rotate through the driving gear 28 and the driven gear 34, so that the turbine rod 29 absorbs the air in the car. Since the diameter of the driving gear 28 is larger than that of the driven gear 34, the rotation speed of the turbine rod 29 can be increased, so that the turbine rod 29 can absorb the air in the car more effectively, and the air in the car enters the cleaning space 11 through the vents of the cleaning cover 10 The air in the cleaning space 11 passes through the ordinary filter 14 to filter out the large molecules in the air, and then passes through the HEPA filter 16 to filter the small molecules in the air. The air continues to pass through the negative ion generator 15 to preliminarily kill the bacteria and viruses in the air. When the air passes through the nano photocatalyst decomposition net 17, the formaldehyde, benzene, bacteria, viruses, etc. in the air are finely killed and filtered. When the turbine rod 29 rotates, the turbine rod 29 drives the reduction driving gear 51 to rotate through the driven bevel gear 53. The speed reduction driving gear 51 drives the piston plate 33 to slide through the speed reduction driven gear 50. Since the diameter of the driving bevel gear 48 is smaller than that of the driven bevel gear 53, and the diameter of the speed reduction driving gear 51 is smaller than that of the speed reduction driven gear 50, the speed of the piston plate 33 can be reduced during the speed transmission process, so that the water in the water cavity 24 flows to the driving gear 28 at a suitable speed, and the piston plate 33 is prevented from exploding the fixed water pipe 25 due to excessive speed. The piston plate 33 pushes the water in the water cavity 24 into the driving gear 28 through the fixed water pipe 25, and the driving gear 28 is After the water in the first atomizing nozzle 31 enters the first atomizing nozzle 31, the water is atomized and sprayed out through the first atomizing nozzle 31. The centrifugal force of the rotation of the turbine rod 29 evenly throws out the water mist so that the purified air is attached to the space between the discharge base 21 and the nano photocatalyst decomposition net 17, increasing the moisture in the air and improving the drying of the air. While the water cavity 24 drains water into the driving gear 28, a part of the water in the water cavity 24 is discharged into the soft water pipe 18 through the cleaning pipe 39. Since the second atomizing nozzle 46 is in a closed state, the water in the soft water pipe 18 is temporarily stored in the soft water pipe 18.

[0037] After using for a period of time, the second atomizing nozzle 46 is started, and the water in the soft water pipe 18 is atomized or sprayed onto the cleaning device through the second atomizing nozzle 46, and then the screw motor 44 is started to rotate the screw 13. The screw 13 drives the cleaning device to slide through the screw slider 40 and the telescopic rod 19, so that the cleaning device cleans the dust accumulated on the ordinary filter 14. At the same time, the inner rod of the telescopic rod 19 is compressed into the outer wall of the telescopic rod 19, and the telescopic rod spring 45 is compressed, so that the cleaning device always rests on the ordinary filter 14 during the sliding process of the telescopic rod 19 to clean the ordinary filter 14. The atomized water produced by the second atomizing nozzle 46 can form the dust on the ordinary filter 14 into small particles to prevent the dust from flying around when the cleaning device cleans the ordinary filter 14. When the cleaning device cleans the dust on the ordinary filter 14 to one side and then resets, the ordinary filter 14 is cleaned again in the same way to make the dust on the ordinary filter 14 The dust is cleaned more cleanly. The width of the cleaning device is longer than the diameter of the ordinary filter 14. All the dust on the ordinary filter 14 can be cleaned at one time. At the same time, the two ultraviolet lamps 32 are started, so that the ultraviolet rays generated by the two ultraviolet lamps 32 are irradiated onto the reflective ball 42. Since the activity of the nano photocatalyst decomposition net 17 will be consumed during use, the activity of the nano photocatalyst decomposition net 17 can be restored by irradiation with ultraviolet rays. Moreover, since the turbine rod 29 is always rotating, the light beams of the two ultraviolet lamps 32 can be evenly irradiated onto the side of the reflective ball 42, and the ultraviolet rays are evenly reflected onto the nano photocatalyst decomposition net 17 through the reflective ball 42, so that the nano photocatalyst decomposition net 17 is activated, so that the nano photocatalyst decomposition net 17 can be cleaned without disassembling, and the vehicle-mounted air purifier can continue to be used during the cleaning of the ordinary filter 14 and the nano photocatalyst decomposition net 17.

Any equivalent structure or equivalent process transformation made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
