[0046] Reference Figure 1-3, is a schematic diagram of the overall structure of a manual-automatic self-cleaning device and method based on an air purifier in one embodiment of the present application;

[0047] Embodiment 1

[0048] A self-cleaning device and method based on a manual and automatic air purifier, the device comprising:

[0049] A housing 1, wherein the housing 1 is provided with an adapter 5, a display window 3 and a storage box 2, wherein the adapter 5 is connected to an external air purifier; the display window 3 is provided on the outer surface of the housing 1, and the storage box 2 is provided in the housing 1;

[0050] The housing 1 has a through opening, and the through opening extends to an interior space 4;

[0051] An air purification component, the air purification component comprises a first filter 14 and a second filter 12, the first filter 14 is arranged in the housing 1 and located above the internal space 4 of the housing 1, and the second filter 12 is located in the middle of the internal space 4 of the housing 1;

[0052] An automated cleaning component, the automated cleaning component comprising a drive motor 11, a track 9, a scraper 10, a bearing and a limit plate;

[0053] The drive motor 11 is arranged in the shell 1, the drive motor 11 is connected to the track 9, the scraper 10 is connected to the guide rail, the output end of the drive motor 11 is connected to one end of the scraper 10, the other end of the scraper 10 passes through the second filter 12 and is embedded in the inner wall of the other end of the shell 1, and there is a bearing connection between the drive motor 11 and the scraper 10, and the drive motor 11 drives the limit plate to move on the track 9.

[0054] The track 9 and the second filter screen 12 are arranged in a parallel structure, and the scraper 10 and the track 9 and the second filter screen 12 are arranged in a vertical structure.

[0055] A pressure sensor 13 is disposed at the end of the first filter 14 , and a light sensor 7 is disposed in the storage box 2 .

[0056] The first filter screen 14 is horizontally placed in the space 4 of the housing 1 , and three second filter screens 12 are vertically placed below the first filter screen 14 .

[0057] The housing 1 further comprises a fan 8 , which is arranged on one side of the second filter screen 12 at the lower end of the housing 1 .

[0058] The scraper 10 has a replaceable silicone strip, and the surface of the silicone strip in contact with the second filter screen 12 is in a serrated structure.

[0059] Specifically, in a living room environment with three long-haired cats, the self-cleaning device of the air purifier automatically starts the monitoring program at 6 o'clock in the morning. The pressure sensors 13 on both sides of the first filter 14 detect that the hair accumulation caused by the cat's activities at night causes the pressure difference to rise to 220Pa. At the same time, the light transmittance of the second filter 12 is reduced to 65% due to the attached cat hair. The system immediately pushes a "clean now" warning through the red breathing light of the display window 3 and the mobile phone APP; after the user clicks to confirm, the drive motor 11 drives the serrated silicone scraper 10 to reciprocate up and down along the track 9 in silent mode, and the scraped hair is drawn into the storage box 2 by the directional airflow generated by the bottom fan 8. During this period, when the light sensor 7 detects that the dust weight in the box reaches 480g, it automatically reduces the scraping frequency to prevent overflow;

[0060] After cleaning is completed, the pressure difference drops back to 130Pa and the transmittance recovers to 85%. The device switches to pet-exclusive mode and shortens the next cleaning cycle to 4 hours. At the same time, the "strong scraping" program is started during the cat's active period in the afternoon. The speed of the scraper 10 is increased by 20% to cope with the continuous shedding of floating hair. It enters sleep mode at 10 pm, turns off the prompt sound, and uses low-speed intermittent scraping to keep the filter unobstructed.

[0068] The light sensor 7 periodically scans the light transmittance on the surface of the second filter 12. When the light transmittance drops below 70% of the initial value, it is determined that the amount of dust attached to the second filter 12 exceeds the standard.

[0073] If the device is in night mode, the sound prompt is disabled and the speed of the scraper 10 is reduced to 50%.

[0074] In the steps of cleaning effect and parameter adjustment,

[0075] After cleaning, recheck ΔP 1 and transmittance, if ΔP 1 If the decrease does not reach 30% or the transmittance recovers less than 50%, it is considered as a cleaning failure;

[0076] Automatically switch to enhanced cleaning mode: increase the number of scraping cycles to 5 times and increase the speed of the drive motor 11 by 20%;

[0077] After three cumulative cleaning failures, the system will be locked and a maintenance request will be pushed to the user terminal.
