Abstract

An air purifier is provided, including a box body and a filter screen inside the box body, an air suction device, a water mist generator, the water mist generator being disposed at one side of the filter screen, the air suction device being configured to inhale outdoor air into an interior of the box body, and the water mist generator being configured to form an ionized water layer.

First claim

What is claimed is:

1. An air purifier, comprising:
a box body,
a filter screen, disposed inside the box body, and
an air suction device, a water mist generator, the water mist generator is disposed at one side of the filter screen, the air suction device being configured to inhale outdoor air into an interior of the box body, and the water mist generator being configured to form an ionized water layer;
the water mist generator comprising a water channel, one or more spraying devices and an ionization generator, the one or more spraying devices are disposed on the water channel, the ionization generator is configured to ionize water mist sprayed by the one or more spraying devices, to form the ionized water layer.

2. The air purifier according to claim 1 , wherein the box body comprises a first panel and a second panel assembled with each other, and the air suction device is disposed at the second panel.

3. The air purifier according to claim 2 , wherein the water mist generator is disposed between the filter screen and the air suction device.

4. The air purifier according to claim 3 , wherein the filter screen, water mist generator and air suction device are in stacked arrangement inside the box body in sequence in a direction from the first panel to the second panel.

5. The air purifier according to claim 1 , wherein a plane where the water channel is disposed is parallel to a plane where the filter screen is disposed.

6. The air purifier according to claim 3 , wherein each of the spraying devices is disposed on an inner side of the water channel.

7. The air purifier according to claim 6 , wherein the spraying device and the ionization generator are alternately disposed around the water channel.

8. The air purifier according to claim 6 , wherein the ionization generator is disposed on top and bottom sides of, or left and right sides of, or around the box body.

9. The air purifier according to claim 1 , further comprising a recovery device recovering water dropped from the ionized water layer after dust is absorbed.

10. The air purifier according to claim 9 , wherein the recovery device is disposed under the water mist generator.

11. The air purifier according to claim 9 , wherein there is provided with a water circulation device that conveys water in the recovery device to the water channel.

12. The air purifier according to claim 11 , wherein the water circulation device comprises a water pump.

13. The air purifier according to claim 9 , further comprising a dust filter device separating water from dust of substance(s) recovered by the recovery device.

14. The air purifier according to claim 13 , wherein the dust filter device comprises a filter sponge.

15. The air purifier according to claim 1 , wherein the water channel is a closed structure.

16. The air purifier according to claim 11 , wherein the filter screen is a multi-layer filter screen.

17. The air purifier according to claim 16 , wherein the filter screen comprises a HEPA filter screen and an activated carbon filter screen.

18. The air purifier according to claim 17 , wherein the HEPA filter screen is disposed at a side of the activated carbon filter screen adjacent to a first panel.
