Abstract

Disclosed are a capture device for purifying air, a purification device, and an air purifier. The capture device for purifying air includes: a housing and a capture assembly. The housing is provided with an air inlet and an air outlet, wherein a cavity, in communication with the air inlet and the air outlet, is defined inside the housing; and the capture assembly is arranged in the cavity, and is located between the air inlet and the air outlet. The capture assembly includes a first rotating disk, a second rotating disk and a cylinder, wherein both the first rotating disk and the second rotating disk are rotatable and rotate in opposite directions; and the cylinder is disposed between the first rotating disk and the second rotating disk.

First claim

What is claimed is:

1. A capture device for purifying air, comprising:
a housing provided with an air inlet and an air outlet, wherein a cavity in communication with the air inlet and the air outlet is defined in the housing; and
a capture member arranged in the cavity and located between the air inlet and the air outlet, wherein the capture member comprises a rotary disk and a cylinder, the rotary disk is provided with a mesh, the rotary disk comprises a first rotary disk and a second rotary disk, the first rotary disk and the second rotary disk are rotatable in opposite directions with respect to one another, the first rotary disk is provided with a first mesh, the second rotary disk is provided with a second mesh, the second rotary disk is arranged downstream of the first rotary disk and is spaced apart from the first rotary disk in an axial direction, the cylinder is arranged between the first rotary disk and the second rotary disk, and an outer peripheral wall of the cylinder is a cylindrical surface and is spaced apart from a side wall of the housing.

2. The capture device for purifying air of claim 1 , wherein at least a portion of the first rotary disk between the cylinder and the housing in a radial direction is formed with the first mesh, and at least a portion of the second rotary disk between the cylinder and the housing in the radial direction is formed with the second mesh.

3. The capture device for purifying air of claim 2 , wherein at least one axial end of the cylinder is formed as an open structure, and the mesh is absent in an area of the rotary disk corresponding to the open structure in the axial direction.

4. The capture device for purifying air of claim 2 , wherein each end of the cylinder is formed as a closed structure.

5. The capture device for purifying air of claim 1 , wherein the cylinder is rotatably arranged between the first rotary disk and the second rotary disk.

6. The capture device for purifying air of claim 5 , wherein the cylinder is fixedly connected to one of the first rotary disk and the second rotary disk.

7. The capture device for purifying air of claim 6 , wherein the cylinder is connected to the second rotary disk, the second rotary disk forms an annular disk, and an inner peripheral edge of the annular disk is connected to the outer peripheral wall of the cylinder.

8. The capture device for purifying air of claim 1 , wherein the cylinder is fixedly arranged between the first rotary disk and the second rotary disk, and is not connected to the first rotary disk and the second rotary disk.

9. The capture device for purifying air of claim 1 , further comprising:
a first driving element for driving the first rotary disk into rotation; and
a second driving element for driving the second rotary disk into rotation.

10. The capture device for purifying air of claim 9 , wherein the first rotary disk is arranged below the second rotary disk and is arranged opposite to the second rotary disk in a vertical direction, the first driving element is arranged below the first rotary disk, and the second driving element is arranged above the second rotary disk.

11. The capture device for purifying air of claim 1 , further comprising a driving assembly, wherein the driving assembly is connected to the first rotary disk and the second rotary disk, the driving assembly comprises a driving device and a reverse device, and the driving device is connected to at least one of the first rotary disk and the second rotary disk through the reverse device to enable the first rotary disk and the second rotary disk to rotate in opposite directions.

12. The capture device for purifying air of claim 1 , wherein both the first rotary disk and the second rotary disk are of a wire-mesh structure.

13. A purification device for purifying air, comprising:
a capture device for purifying air, comprising:
a housing provided with an air inlet and an air outlet, wherein a cavity in communication with the air inlet and the air outlet is defined in the housing; and
a capture member arranged in the cavity and located between the air inlet and the air outlet, wherein the capture member comprises a rotary disk and a cylinder, the rotary disk is provided with a mesh, the rotary disk comprises a first rotary disk and a second rotary disk, the first rotary disk and the second rotary disk are rotatable in opposite directions with respect to one another, the first rotary disk is provided with a first mesh, the second rotary disk is provided with a second mesh, the second rotary disk is arranged downstream of the first rotary disk and is spaced apart from the first rotary disk in an axial direction, the cylinder is arranged between the first rotary disk and the second rotary disk, and an outer peripheral wall of the cylinder is a cylindrical surface and is spaced apart from a side wall of the housing; and

a washing and purifying assembly which is arranged in the cavity and located between the air inlet and the first rotary disk and is configured to wash and purify the air entered through the air inlet.

14. The purification device for purifying air of claim 13 , wherein at least a portion of the first rotary disk between the cylinder and the housing in a radial direction is formed with the first mesh, and at least a portion of the second rotary disk between the cylinder and the housing in the radial direction is formed with the second mesh.

15. The purification device for purifying air of claim 14 , wherein at least one axial end of the cylinder is formed as an open structure, and the mesh is absent in an area of the rotary disk corresponding to the open structure in the axial direction.

16. The purification device for purifying air of claim 14 , wherein each end of the cylinder is formed as a closed structure.

17. The purification device for purifying air of claim 13 , wherein the cylinder is rotatably arranged between the first rotary disk and the second rotary disk.

18. The purification device for purifying air of claim 17 , wherein the cylinder is fixedly connected to one of the first rotary disk and the second rotary disk.

19. The purification device for purifying air of claim 18 , wherein the cylinder is connected to the second rotary disk, the second rotary disk forms an annular disk, and an inner peripheral edge of the annular disk is connected to the outer peripheral wall of the cylinder.

20. An air purifier, comprising:
