The present invention relates to an air-ionization dust collecting and purifying device, comprising a main body. An air intake and an air outtake are arranged on the main body and an inner lining board, a dust collecting device, a blowing fan, a high efficiency filter, an ion emitting plate, an ion guiding plate, a controller, and a high pressure bag are arranged in the main body. The inner lining board is arranged on the inner side wall of the main body the ion emitting plate and the ion guiding plate are plug-connected to the inner side wall of the inner lining board in parallel and at interval the dust collecting device is also plug-connected to the inner side wall of the inner lining board the blowing fan is fixed on the main body and the high efficiency filter is also plug-connected to the inner side wall of the inner lining board. The inner lining board is further provided with an air channel, and air sucked from the air intake passes through the ion emitting plate, the ion guiding plate, the dust collecting device, the blowing fan, and the high efficiency filter in sequence before being discharged from the air outtake. The device in the present invention has such features as being simple in assembly, low in cost, small in size, safe and reliable, free of ozone and power discharge noise, high in dust collection efficiency, and easy to clean.La présente invention concerne un dispositif de collecte de poussière et de purification à ionisation dair, comprenant un corps principal.
