Description

Technical Field

[0001] The present invention relates to the technical field related to air purifiers, and in particular to a wet air purifier. Background Art

[0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to products that can absorb, decompose or transform various air pollutants and effectively improve air cleanliness. Air purifiers are divided into purification type and humidification purification type according to purification needs. If you are located in an area with moderate indoor humidity, or if you do not have high requirements for air quality, then purchasing a purification type air purifier will meet your needs. If you are located in a drier area, often use the air conditioner to dehumidify the air, causing dry indoor air, or if you have high requirements for air quality, then purchase a purification and humidification type air purifier.

[0003] The utility model patent "Air Purifier Humidifier" with application number CN201922178249.2 in my country discloses an air purifier humidifier, which is provided with at least one set of nozzles. When the water pump is running, the water flow sprayed by each set of nozzles is counteracted to form a water curtain. The water of the water curtain is sprinkled on the wet film. Under the action of gravity, the water penetrates downward along the surface of the wet film and is fully absorbed by the wet film. Since the wet film has excellent water absorption, a uniform water film is formed, which moistens the air when the air passes through, achieving a uniform humidification effect.

[0004] However, the above patent still has some shortcomings. The existing humidification and purification type air purifiers form water films in various ways, which humidify the air while absorbing dust. However, they cannot be adjusted according to the actual weather during use. In the rainy season with high humidity, not only can the air humidity not be reduced, but it can also increase the air humidity during use. Therefore, a wet air purifier is designed.

[0031] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0032] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0033] like Figure 1-7 As shown, a wet air purifier comprises: a shell 1, a water storage tank 2 with an open top mounted inside the shell 1, a horizontal inner drum 3 rotatably connected to the open top of the water storage tank 2, an outer drum 4 axially connected to the inner drum 3 through a first bearing and sleeved on the outer side of the inner drum 3, an air intake unit mounted on the inner wall of the shell 1, a driving unit connected to the inner drum 3 and the outer drum 4 through a transmission mechanism to drive the inner drum 3 and the outer drum 4 to rotate in opposite directions, and an air intake pipe 5 coaxially mounted on one end of the inner drum 3 away from the transmission mechanism and communicating with the inner drum 3, wherein the air intake unit is movably connected to the end of the air intake pipe 5;

[0034] The side walls of the inner drum 3 and the outer drum 4 are both penetrated with a plurality of exhaust holes 6. When the water storage tank 2 is in a water-free state, filter material can be filled between the inner drum 3 and the outer drum 4 to form a filter layer.

[0035] In the above technical solution, the shell 1 is opened, and water is poured into the water tank 2 so that the water level is higher than the lowest point of the inner drum 3 and the outer drum 4. The driving unit drives the inner drum 3 and the outer drum 4 to rotate, so that a layer of water film is formed on the surface thereof. The air intake unit transports the outside air into the inner drum 3, and the dust in the air adheres to the water film of the inner drum 3 and the outer drum 4. In the part where the inner drum 3 and the outer drum 4 are in contact with the water, not only a new water film can be formed, but the dust adhered to the inner drum 3 and the outer drum 4 will also fall into the water, and the air will also take away part of the moisture to achieve a humidification effect.

[0036] When it is needed to be used as a dry air purifier, the water in the water tank 2 is drained, and then filter material is filled between the inner drum 3 and the outer drum 4. The filter material can be existing filter materials such as non-woven fabrics. At this time, the drive unit does not need to be started. After the gas enters the inner drum 3, it will pass through the filter layer and then be discharged from the exhaust hole 6 on the outer drum 4. Some hygroscopic material can also be placed between the inner drum and the outer drum to play a dehumidification role.

[0037] The driving unit drives the inner drum 3 and the outer drum 4 to rotate in opposite directions through the transmission mechanism. The inner drum 3 and the outer drum 4 will drive the water to flow in different directions, so that the two water flows impact each other, thereby disrupting the normal flow of water. The disturbed water flow is conducive to flushing the dust adsorbed on the inner drum 3 and the outer drum 4.

[0038] In a preferred embodiment of the invention, the inner drum 3 includes a first cylinder 7 and a pair of first end covers 8 fixedly mounted on both ends of the first cylinder 7, the air intake pipe 5 is coaxially fixedly connected to the corresponding first end covers 8, the outer drum 4 includes a second cylinder 9 and a pair of second end covers 10 fixedly mounted on both ends of the second cylinder 9, the second end covers 10 are axially connected to the corresponding first end covers 8 through first bearings, at least one second end cover 10 is provided with a window, and the second end cover 10 is connected to a cover plate 11 capable of covering the window through a plurality of first mounting bolts.
