[0002] Air filter refers to air filtering device, which is generally used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic machinery and communication equipment. There are primary filter, medium filter, high efficiency filter and sub-high efficiency filter. When the air filter is in use, the filter screen filters the air, so that dust accumulates on the surface of the filter screen for a long time. The dust accumulation on the filter screen is easy to cause the filter screen to be blocked, and the filter screen needs to be replaced.

[0003] However, the existing air filter takes time to replace the filter, resulting in downtime of the air filtration. The dust removal effect of the filter is poor, so the filter cannot achieve the purpose of filtering the air.

[0010] As an improvement of the above technical solution, the air blowing pipes are distributed at equal intervals.

[0011] As an improvement of the above technical solution, the dust exhaust component includes a dust exhaust pipe, and support rings and supporting rings are respectively welded on the surfaces of both ends of the dust exhaust pipe, and a pneumatic telescopic rod is installed on the surface of the support ring. A pressure limiting ring is fixed to the telescopic end of the pneumatic telescopic rod, and the pressure limiting ring is movably sleeved on the outside of the dust exhaust pipe, and the pressure limiting ring is close to the supporting ring, and a dust exhaust fan for discharging air downward is installed in the dust exhaust pipe.

[0014] As an improvement of the above technical solution, the heating resistance wire is a mesh structure, and two heating resistance wires are provided.

[0015] Beneficial effects of the present invention:

[0016] 1. The automatic cleaning device composed of a dust removal component and a dust exhaust component makes it easy for the dust removal component to remove dust on the surface of the primary filter through a scraping mechanism and a blowing mechanism, thereby keeping the surface of the primary filter clean. The blowing mechanism causes the dust on the surface of the primary filter to float by blowing air, thereby facilitating the floating dust to be discharged by the dust exhaust component, thereby increasing the convenience of automatic cleaning of the filter. The cleaned filter is convenient for continuous filtering of the air, reducing the number of times the filter surface needs to be replaced after being covered with dust.

[0017] 2. The scraping mechanism is composed of a bracket, a reduction motor, a shaft frame, a mounting seat, a scraper frame, a movable cavity, a spring, and a rubber scraper. The reduction motor installed in the middle of the bracket rotates the shaft frame through the output shaft, and the shaft frame rotates the scraper frame through the mounting seat. The rubber scraper is movably installed in the movable cavity set in the scraper frame through the spring. When the scraper frame rotates, the rubber scraper scrapes the dust on the surface of the primary filter, which solves the problem that the dust on the surface of the primary filter is difficult to scrape.

[0018] 3. The side scraper is fixed at the end of the scraper frame, and a support bar is fixed between the scraper frame and the side scraper, which increases the stability of the side scraper fixed to the end of the scraper frame. At the same time, the side scraper is in contact with the inner surface of the shell, so that when the scraper frame rotates, the dust on the inner surface of the shell is scraped off by the side scraper.

[0019] 4. Through the blowing mechanism composed of a high-pressure fan, an air duct and an air blowing pipe, the high-pressure fan is installed on the surface of the mounting seat, and the air duct is installed at the air outlet of the high-pressure fan. At the same time, the air blowing pipe array is distributed on the air duct, so that the air blown by the high-pressure fan enters the air duct and is blown out by the air blowing pipe, so that the air blown by the air blowing pipe can blow up the dust on the surface of the primary filter.

[0020] 5. The dust removal parts are composed of a dust exhaust pipe, a dust exhaust fan, a support ring, a pneumatic telescopic rod, a pressure limiting ring and a support ring. The support ring and the support ring are welded at both ends of the dust exhaust pipe, so that the pneumatic telescopic rod is installed on the support ring to carry the pressure limiting ring to squeeze the support ring, so that when the filter bag is put on the outside of the support ring, the pressure limiting ring and the support ring cooperate to clamp and fix the filter bag, so that the dust inside the shell can enter the filter bag under the action of the dust exhaust fan.

[0021] 6. The primary filter is installed in the shell and limited by the support plate, which increases the stability of the primary filter installed in the shell. At the same time, a secondary filter is also installed in the shell to facilitate the cooperation of the primary and secondary filters to filter the air. The heating resistor wire arranged in the shell is used to heat the secondary filter to prevent the secondary filter from absorbing moisture and getting damp. BRIEF DESCRIPTION OF THE DRAWINGS
