Water-washable air purifier

Abstract

A water-washing air purifier includes a housing, a flow guiding unit, a water spraying unit, and an air supply unit. The housing defines a spraying space within its interior. The spraying space has an air inlet for introducing outside air into the spraying space. The flow guiding unit includes a vortex basin. The water spraying unit, positioned above the flow guiding unit, sprays water. The air supply unit is located within the spraying space and above the flow guiding unit. The air supply unit includes a driveable fan blade that blows air downwards from the air inlet, causing the water sprayed from the nozzles to form a vortex in the vortex basin. The vortex in the vortex basin mixes with pollutants in the air blown by the air supply unit, thereby removing pollutants from the air passing through the vortex basin. This eliminates the need for filters and filter replacements, achieving both environmental friendliness and improved ease of use.

4. The water-washable air purifier as described in claim 3 further includes a base, wherein, The base houses the vortex basin and includes an upper cover located above the vortex basin for the lower tube to pass through. The top surface of the upper cover has at least one air outlet that connects the space inside the basin with the outside. The air outlet is used to discharge the air that has passed through the space inside the basin and come into contact with the vortex formed by the vortex basin to the outside.

5. The water-washable air purifier as described in claim 4, wherein, The upper cover has a ring cover portion surrounding the lower pipe portion, the ring cover portion forming at least one air outlet and suitable for placing at least one plant on it; the upper pipe portion has a plurality of microholes penetrating the inner and outer surfaces of the upper pipe portion, the microholes being aligned with the ring cover portion and allowing the water flow portion flowing along the inner surface of the upper pipe portion to pass through.

6. The water-washable air purifier as described in claim 5 further comprises at least one light-emitting element, wherein, The light-emitting element is located at the bottom of the housing and outside the upper tube. The light-emitting element is adapted to emit light toward the plant located on the ring cover.

7. The water-washable air purifier as described in claim 5, wherein, The guide tube has an inner body with an inner surface defining the guide space, and an outer body located on the opposite side of the inner surface of the inner body. The material of the inner body is selected from a mixture of cement and binchotan charcoal, and the material of the outer body is selected from a mixture of cement and diatomaceous earth.

8. The water-washable air purifier as claimed in claim 1, further comprising a base, wherein, The inner surface of the vortex basin defines an internal space for the flow of the vortex. The base is placed inside the vortex basin, and the interior of the base defines a water storage space located below the vortex basin for storing water. The vortex basin has an overflow hole that connects the internal space and the water storage space and is adjacent to the periphery of the vortex basin. The overflow hole allows a portion of the vortex flowing in the internal space to pass through.

9. The water-washable air purifier as described in claim 8, wherein, The vortex basin also has at least one rib protruding upward from the inner surface of the vortex basin, the rib being positioned below the overflow hole.

10. The water-washing air purifier as described in claim 8, wherein, The sprinkler unit also includes an inlet pipe connecting the water storage space and the at least one nozzle, and a water pump installed in the inlet pipe, which can be controlled to guide water in the water storage space to the at least one nozzle.

11. The water-washable air purifier as described in claim 8 further includes a heat dissipation unit, wherein, The base also includes a bottom wall, a seat enclosure extending upward from the periphery of the bottom wall, and a partition connecting the two opposite sides of the bottom wall and the seat enclosure. The bottom wall, the seat enclosure, and the two opposite sides of the partition define the water storage space and the receiving space, respectively. The heat dissipation unit is located in the receiving space and includes a cooling chip. The cooling chip has a cooling end and a heating end located on both sides. The cooling end is disposed on the partition and exchanges heat with the water in the water storage space through the partition, thereby cooling the water in the water storage space.

12. The water-washable air purifier as described in claim 11, wherein, The heat dissipation unit also includes a heat spreader plate disposed on the bottom wall of the base, and a heat pipe connecting the heating end and the heat spreader plate. After the heating end of the cooling chip exchanges heat with the water in the cooling end and the water storage space, it generates waste heat, which is then transferred to the outside through the heat pipe, the heat spreader plate and the bottom wall of the base in sequence.

13. The water-washable air purifier as described in claim 1, wherein, The housing has a shell wall defining the spraying space; the cross-section of the inner surface of the vortex basin defines an imaginary circle and a plurality of tangent directions that are tangent to different parts of the circumference of the imaginary circle; the spraying unit includes a surrounding pipe extending horizontally along the inner surface of the shell wall, and a plurality of nozzles extending from the surrounding pipe along a plurality of tangent directions, the plurality of nozzles being spaced apart along the extension direction of the surrounding pipe, the plurality of nozzles being used to spray a plurality of water flows along a plurality of tangent directions.
