The contact area between the filter screen 23 and the deozone filter screen 25 and the air is such that the gaseous pollutant removal filter screen 23 and the deozone filter screen 25 can purify the air better.

Dust removal device 50 comprises the dust removal box 51 that communicates with the second air inlet pipe 13, is located at the motor 54 of dust removal box 51 tops, is located at the rotating shaft 55 in the dust removal case 51, is located at the stirring blade 56 on the rotating shaft 55 and is arranged on the dust removal box. The water spray mechanism 57 at the top of the box 51; the side wall of the dust removal box 51 is provided with an air inlet 52 and a drain pipe 53, and the air inlet 52 is located between the air inlet end of the second air inlet pipe 13 and the water inlet end of the drain pipe 53 ; The motor 54 shown is connected to the rotating shaft 55 for driving the rotating shaft 55 to rotate with the stirring blade 56 . When the dust removal device 50 removes dust from the air in and out of the outside world, the air entering the dust removal box 51 from the air inlet 52 moves upward, and the water sprayed by the water spray mechanism 57 moves downward under the action of its own gravity. 51 in the reverse contact; the motor 54 drives the rotating shaft 55 to rotate with the stirring blade 56, so that the air and water are fully mixed and contacted, so that the dust with a larger particle size in the air can be deposited in the water as much as possible, and with it The water falls to the bottom of the dust removal box 51, and finally the water with dust is discharged to the outside of the dust removal box 51 through the drain pipe 53, realizing the purpose of removing dust particles with larger particle diameters in the air by water, and the purified air Then enter the purification box 10 through the second air inlet pipe 13 and be further purified by the purification assembly, which reduces the dust removal load of the primary filter screen 21 of the purification assembly.

The dust-removing box 51 is provided with a water-retaining cover 58 corresponding to the air inlet 52, and the bottom end of the water-retaining cover 58 is open. The water shield 58 can prevent the water in the dust removal box 51 from running to the outside of the dust removal box 51 through the air inlet 52 .

In this embodiment, there is one stirring blade 56 , which is helically arranged on the rotating shaft 55 .

Spray mechanism 57 comprises shower head 571 and water inlet pipe 572, and shower head 571 is positioned at the top of first cavity, and one end of water inlet pipe 572 connects shower head 571, and the other end stretches out of casing, and water inlet pipe 572 is provided with the water inlet of connection control device. Control valve 573. When it is detected that the concentration of dust in the outside air is greater than a predetermined concentration value, the control device device controls the opening of the second air intake control valve 14, and also controls the opening of the water intake control valve 573, so that the external air enters the dust removal box 51 At the same time, the water spray mechanism 57 sprays water to the air moving upward under the force of the external water pump, so as to remove dust particles with larger particle diameters in the air. In this embodiment, there are four water spraying mechanisms 57 , and the water spraying mechanisms 57 are evenly distributed around the center of the rotating shaft 55 , so that water can be evenly sprayed into the dust removal box 51 .

The working principle of the dual-choice air purifier of this embodiment is: when the dust concentration in the outside world is at a normal value, the first air intake control valve 12 is opened, the second air intake control valve 14 is closed, the exhaust fan 30 is started, and the air in the outside world is directly Enter the body of the purification box 10 through the first air inlet pipe 11 , be purified when passing through the purification assembly, and finally flow out of the purification box 10 through the air outlet 15 . The dust concentration sensor 40 detects the concentration of dust in the outside air, and sends the detected dust concentration information to the control device, and the control device compares and analyzes the dust concentration information sent by the dust concentration sensor 40; When the dust concentration is higher than the predetermined dust concentration, the control device controls the first air intake control valve 12 to close, controls the second air intake control valve 14 and the water intake control valve 573 of each water spray mechanism 57 to open, and controls the motor 54 to start, The motor 54 drives the rotating shaft 55 to rotate with the stirring blade 56. Under the force of the exhaust fan 30, the outside air enters the dust removal box 51 through the air inlet 52 of the dust removal box 51, and contacts with the falling water in reverse. , under the agitation of the stirring blade 56, the water is in full contact with the dust in the air, so that 80% of the dust with a larger particle size in the air can be deposited in the water, and the water after dust removal falls to the bottom of the dust removal box 51. Bottom, and discharge to the outside of the dust removal box 51 through the drain pipe 53. Then the air dedusted by water enters the purification box 10 through the second air intake pipe, and is purified again when passing through the purification assembly, and finally the purified air flows out of the purification box 10 through the air outlet 15 .

The dual-selection air purifier of the present utility model can selectively let the dust removal device 50 assist the primary effect filter screen 21 of the purification component to remove dust particles with larger particle diameters in the air by measuring the dust concentration of the outside air. When it is detected that the dust concentration in the outside air is not large, the dust removal device 50 does not work, and the outside air directly enters the purification box 10 to be purified by the purification components; when it is detected that the dust concentration in the outside air is too large, the dust removal device 50 work, remove most of the larger dust particles in the air, and send the dedusted air into the purification box 10 to be purified by the purification assembly again, reducing the dust removal load of the primary effect filter screen 21 of the purification assembly. The frequency of disassembly and cleaning of the primary filter screen 21 is reduced.

The above-mentioned embodiments only express several implementation modes of the utility model, and the description thereof is relatively specific and detailed, but it should not be understood as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
