The function of the high-voltage electrode is to directly ionize the water molecules in the air into H free radicals and OH free radicals, and at the same time wrap the water molecules, and use the hydrophilicity of bacteria and viruses to remove bacteria and viruses; Positive and negative ions further attract positively and negatively charged bacteria and odors to achieve efficient purification of bacteria, viruses, and odors. At the same time, positive and negative ions return to the air in the form of water molecules, avoiding secondary pollution.

The sensor component can detect the content of particulate matter and gas pollutants in the indoor air as well as the indoor humidity, so as to provide a basis for judging whether the purifier is turned on and how many gears are turned on.

The function of the air inlet of the sensor is to inhale indoor air for the sensor component to detect the concentration of various pollutants in the room.

The water tank includes a water pump, a tray, and a bucket, and its function is to provide circulating water for the water film to humidify the water film.

Advantages and positive effects:

The air purifier of the utility model has better removal effects on particle pollutants, gas pollutants and biological pollutants. The annular airflow formed by the air inlet from the rear and the air outlet from the upper side will not blow up the dust on the ground, and reduce the short circuit coefficient of the airflow; Effective removal of dust above 0.3μm, gas soluble in water, and bacteria and viruses without secondary pollution; the setting of each filter and fan position realizes the purification of indoor air while protecting the fan from pollution; The set sensor components provide a basis for judging whether the purifier needs to be turned on and how many levels to turn on; at the same time, the set control panel can realize manual or automatic adjustment of air volume and other control functions.
