[0039] Specifically, the rolling structure 3 comprises an outer frame 301, the back of the vehicle-mounted air sterilizer body 1 is provided with the outer frame 301, the outer frame 301 is fixed with a rolling ring 302, the outer frame 301 is fixed with a shielding plate 303, the rolling ring 302 and the outer frame 301 form an annular sliding groove 304, the limiting structure 8 comprises a driving shaft 801, the sliding groove 304 is slidably provided with the driving shaft 801, the driving shaft 801 is provided with a through hole 802, the power cord 2 penetrates through the through hole 802, the driving shaft 801 and the pull rod 803 are slidably connected, the pull rod 803 is fixed with a rubber pad 805, the rubber pad 805 abuts against the shielding plate 303, the driving shaft 801 is fixed with a stop block 806, the stop block 806 abuts against the second spring 804 between the pull rod 803;

[0041] A control method of a vehicle-mounted air sterilizer, comprising the following steps:

[0042] S1: when used in the car, the excess power cord 2 is rolled up by the rolling structure 3, and the power cord 2 is limited by the limiting structure 8; the car interior is disinfected by the butt joint structure 6;

[0043] S2: the dustproof structure 4 is used to protect the air inlet position, and when cleaning, the dustproof structure 4 can be disassembled;

[0044] S3: when used externally, the wearing structure 7 is connected to the butt joint structure 6, and the user wears the wearing structure 7, so that the fresh air is gathered on the face of the user.

[0045] The present application is used, when adjusting the length of the power cord 2, by pulling the pull rod 803, the sliding connection between the pull rod 803 and the drive shaft 801 is achieved, the pull rod 803 is pressed to compress the second spring 804, and the rubber pad 805 is not pressed against the baffle 303. If the power cord 2 is pulled out, the power cord 2 is pulled to drive the drive shaft 801 to slide counterclockwise in the sliding groove 304. When the power cord 2 is reeled in, the pull rod 803 is pushed to drive the drive shaft 801 to slide clockwise in the sliding groove 304, so that the power cord 2 is reeled on the reel 302. When the length adjustment of the power cord 2 is completed, the pull rod 803 is released, the second spring 804 is stretched to drive the pull rod 803 to move towards the baffle 303, so that the rubber pad 805 is pressed against the baffle 303, preventing the drive shaft 801 from moving, thereby facilitating the positioning of the reeled power cord 2, improving the neatness and stability.

[0046] When the first filter screen 401 needs to be cleaned, the hand pulls the limiting rod 407 to make the limiting rod 407 slide with the guide rod 406, the limiting rod 407 is pressed to compress the first spring 405, and the limiting rod 407 is separated from the limiting groove 408. Then the fixed frame 402 is pulled down to make the clamping block 403 separate from the clamping groove 404, thereby facilitating the quick disassembly of the fixed frame 402 for cleaning the first filter screen 401. After cleaning, the fixed frame 402 is pushed up to make the clamping block 403 engage with the clamping groove 404, and then the limiting rod 407 is released. The first spring 405 is stretched to push the limiting rod 407 to slide with the guide rod 406, so that the limiting rod 407 engages with the limiting groove 408. The clamping block 403 prevents the fixed frame 402 from moving forward and backward, and the limiting rod 407 prevents the fixed frame 402 from moving up and down, thereby improving the stability.

[0047] When used in the car, the purified air flow passes through the exhaust port 9 and is discharged from the second filter screen 603. The second filter screen 603 prevents dust from falling into the exhaust port 9 when not in use. When the vehicle-mounted air sterilizer body 1 is used externally, the push block 601 is pushed counterclockwise to drive the limiting ring 604 to rotate counterclockwise, so that the limiting ring 604 moves upward spirally, reducing the resistance of the limiting ring 604 to the elastic sheet 606. The fixed ring 602 is removed, and then the hose 701 is engaged with the inner ring 605. Then the push block 601 is pushed clockwise to drive the limiting ring 604 to rotate clockwise, so that the limiting ring 604 moves downward spirally, increasing the resistance of the limiting ring 604 to the elastic sheet 606. The elastic sheet 606 is pressed against the outside of the hose 701, thereby installing the hose 701. Then the face mask 702 is worn, so that the purified fresh air flow is gathered on the user's face through the face mask 702, improving the use effect.
