Abstract

The method and system disclosed herein present a purification device for purifying air, and an air purifier having the same. The purification device for purifying air comprises a housing, one or more purification assemblies, one or more water inlet pipes, one or more capture assemblies, and an electric motor. The housing is provided with an air inlet and an air outlet. A cavity, in communication with the air inlet and the air outlet, is defined inside the housing. Each of the one or more purification assemblies is rotatably arranged in the cavity, and is located between the air inlet and the air outlet. Each of the one or more capture assemblies is rotatably arranged at a downstream side of the one or more purification assemblies. The electric motor is used for driving the one or more purification assemblies and the one or more capture assemblies.

First claim

What is claimed is:

a housing provided with an air inlet and an air outlet, wherein a cavity communicating with the air inlet and the air outlet is defined in the housing;
one or more purifying assemblies each rotatably arranged in the cavity and located between the air inlet and the air outlet, wherein a respective purifying assembly of the one or more purifying assemblies comprises a first rotary cylinder and a first rotary disk, the first rotary cylinder is spaced apart from a side wall of the housing, a side wall of the first rotary cylinder is provided with a first mesh in a circumferential direction of the side wall of the first rotary cylinder, the first rotary disk is connected downstream of the first rotary cylinder, and a portion of the first rotary disk, which is located between the first rotary cylinder and the housing in a radial direction, is provided with a second mesh;
one or more water inlet pipes each comprising a water inflow end and a water discharge end, the water discharge end being provided with a plurality of circumferentially distributed water injection nozzles, and the water discharge end extending into the first rotary cylinder;
one or more capture members each rotatably arranged downstream of the purifying assembly, wherein a respective capture member of the one or more capture members comprises a second rotary cylinder and a second rotary disk, an outer circumferential wall of the second rotary cylinder is a cylindrical surface, the second rotary cylinder is spaced apart from the side wall of the housing, the second rotary disk is connected downstream of the second rotary cylinder, and a portion of the second rotary disk, which is located between the second rotary cylinder and the housing at least in the radial direction, is provided with a third mesh; and
a motor configured to drive the one or more purifying assemblies and the one or more capture members into rotation.

2. The purification device for purifying air of claim 1 , wherein the motor is arranged above the one or more capture members to drive the one or more purifying assemblies and the one or more capture members to rotate synchronously.

3. The purification device for purifying air of claim 1 , wherein the water inflow end of each of the one or more water inlet pipes is located at a lower part of the housing, and the water discharge end is arranged at a position higher than the water inflow end.

4. The purification device for purifying air of claim 1 , wherein the first rotary disk is in a form of an annular disk, and an inner side wall of the annular disk is connected with an outer side wall of the first rotary cylinder.

5. The purification device for purifying air of claim 1 , wherein the first rotary disk is in a form of a circular disk, the first rotary cylinder is in a form of a hollow structure with an open upper end, and the first rotary disk closes an upper end of the first rotary cylinder.

6. The purification device for purifying air of claim 1 , wherein each of an upper end and a lower end of the first rotary cylinder is formed as a closed structure, and a bottom wall of the first rotary cylinder is provided with an opening adapted to be passed by the one or more water inlet pipes.

7. The purification device for purifying air of claim 1 , further comprising a water pan, wherein the water pan is arranged at a bottom of the housing, and the water inflow end is located in the water pan.

8. The purification device for purifying air of claim 1 , wherein the housing is in a form of a cylinder, and a radius of the first rotary cylinder is 0.2 to 0.7 times a radius of the housing.

9. The purification device for purifying air of claim 8 , wherein an axial height of the first rotary cylinder is 0.1 to 0.8 times the radius of the housing.

10. The purification device for purifying air of claim 1 , wherein the side wall of the first rotary cylinder is in a form of a wire mesh structure having 20 to 100 meshes.

11. The purification device for purifying air of claim 1 , wherein a porosity of the side wall of the first rotary cylinder is 0.3 to 0.7.

12. The purification device for purifying air of claim 1 , wherein the air outlet is arranged at a position higher than the air inlet, the one or more purifying assemblies are sequentially stacked in an up and down direction, and the one or more capture members are arranged at an upper end of an uppermost purifying assembly of the one or more purifying assemblies.

13. The purification device for purifying air of claim 12 , wherein the one or more capture members are sequentially stacked in the up and down direction, and each of the one or more capture members is arranged above the one or more purifying assemblies.

14. The purification device for purifying air of claim 1 , wherein the air outlet is arranged at a position higher than the air inlet, the one or more capture members and the one or more purifying assemblies are stacked onto one another in the up and down direction, and at least one of the one or more capture members is located at a position closest to the air outlet.

15. The purification device for purifying air of claim 12 , wherein the one or more water inlet pipes pass through the one or more purifying assemblies, and each of the one or more water inlet pipes is provided with a water injection nozzle corresponding to the first rotary cylinder of each of the one or more purifying assemblies.

16. The purification device for purifying air of claim 12 , wherein the water discharge end of each of the one or more water inlet pipes extends into the first rotary cylinder of a corresponding purifying assembly of the one or more purifying assemblies.

17. An air purifier comprising a purification device for purifying air, wherein the purification device for purifying air comprises:
a housing provided with an air inlet and an air outlet, wherein a cavity communicating with the air inlet and the air outlet is defined in the housing;
