In one embodiment, the first purification assembly 70 comprises an ion sterilization screen. The ion sterilization filter screen generates a large amount of electrons under the action of an external electric field to bombard pollutant molecules in the air, so that macromolecular pollutants are converted into micromolecular safe substances. To ensure a better ion purification effect, the air volume in the second air duct 30 is usually increasedIs large, up to 600m³In this embodiment, the purified ion wind is finally blown out from the second wind outlet 102 at the top of the housing 10, so that the ion wind can be prevented from blowing directly to the user. Optionally, the first purification assembly 70 includes a primary filter screen, an ion sterilization filter screen and an activated carbon adsorption filter screen arranged in sequence along the air intake direction. Can carry out the prefilter to the air that gets into by second air intake 104 through the primary filter screen, filter some macromolecule particulate matters, play the ion bactericidal effect through the ion filter screen that disinfects, the peculiar smell in the rethread active carbon adsorption filter screen gets rid of the air to further optimize purifying effect.

In one embodiment, the purification module further includes a second purification assembly 80 disposed at the air outlet side of the second fan assembly 50. For example, in the present embodiment, the second purge unit 80 is provided at the air blowing port of the air guide casing 51 of the second fan unit 50, and the air flow in the air guide casing 51 can be purged by the second purge unit 80 while being sent from the air blowing port. The second purifying component 80 includes, but is not limited to, HEPA net, activated carbon filter net, TVOC (total volatile organic compound) filter net, formaldehyde removing filter net, electrostatic dust collecting net, ion generator, ultraviolet sterilizer, etc. to achieve air purifying effect.

As shown in fig. 10, in the present embodiment, the purification module includes a first purification assembly 70 and a second purification assembly 80, wherein the first purification assembly 70 is provided with two groups, which are respectively disposed on two air inlet sides of the second fan assembly 50, and the second purification assembly 80 is disposed on an air outlet side of the second fan assembly 50. Wherein, the first purification component 70 may comprise a plasma screen to realize the ion sterilization effect, and the second purification component 80 may comprise a formaldehyde removal screen, such as a manganese screen, to realize the formaldehyde removal effect. So, can play multiple purification effect to the air current in the second wind channel 30, further promote purifying effect.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
