Technical Field

[0001] The utility model belongs to the field of air purification, and in particular relates to a self-cleaning air purification device. Background Art

[0002] Air purification refers to providing overall solutions for various indoor environmental problems, such as sterilization and disinfection, dust reduction and haze removal, removal of harmful decoration residues and odors, etc., to improve living and working conditions and enhance physical and mental health.

[0003] A Chinese patent with publication number CN215983073U discloses an air purification device with automatic cleaning function, comprising a main body; a cleaning device and a drying device are also arranged on the main body; an air inlet is arranged on the left side of the main body, and an air outlet is arranged on the right side of the main body; a coarse-effect filter, an electrostatic purification unit, and a coupled catalytic plate are arranged in sequence from left to right in the main body; the cleaning device comprises a water spray rod and a water nozzle; a water inlet is arranged at the upper end of the water spray rod, and the water nozzles are evenly distributed on the water spray rod; the drying device comprises a fan, a heating module, an air intake pipe, a gas spray rod, and a gas nozzle; the upper end of the air intake pipe is connected to the heating module, and the gas nozzles are evenly distributed on the gas spray rod; the water spray rod and the gas spray rod are both arranged on a transmission rail; the transmission rail is driven by a motor.

[0004] During use of the air purification device disclosed in the application, the cleaning device flushes the coarse-effect filter and the electrostatic purification unit on both sides.
