Compared with the locking components arranged in the same direction, the staggered locking components can make the top plate 4 more evenly stressed and improve the degree of fitting, through The top plate 4 cooperates with the slot 5 to fix the upper end of the filter plate 2, and the lower end of the filter plate 2 is fitted by the elastic component, and the filter plate 2 is locked under the action of the elastic component by the locking component. Compared with the existing device, it avoids the need to use tools to remove the screws and the problem of complicated steps and operations, and improves the replacement efficiency. An air outlet 7 is opened at the center of the top surface of the outer shell 1, and an air inlet 8 is opened at the center of the two side walls of the outer shell 1 parallel to the filter plate 2. A fan 9 for blowing air upward is fixedly installed below the air outlet 7, and a humidifying component for humidifying the air is fixed above the air outlet 7. The humidity of the air is increased by the humidifying component.

[0021] Reference Figure 1-3 The elastic component includes a plurality of springs 10 fixedly connected to the bottom wall of the through groove 3 in a linear array, and a pressure plate 11 is fixedly connected to the top ends of the plurality of springs 10 on the same side, and the top surface of the pressure plate 11 is in contact with the bottom surface of the filter plate 2. The pressure plate 11 and the spring 10 can better fit the filter plate 2 to the inner bottom wall of the outer shell 1, and the filter plate 2 can be automatically popped out, thereby further improving the replacement efficiency.

[0022] The humidifying assembly includes an annular atomizer 12 fixedly connected to the top surface of the shell 1, a water tank 13 is fixedly installed inside the shell 1 below the air outlet 7, the water outlet of the water tank 13 is connected to a water pipe 14, a water pump should be installed in the water tank 13, one end of the water pump is connected to the water pipe 14, and the other end of the water pipe 14 is connected to the atomizer 12. The atomizer 12 is a prior art, which breaks up the water droplets into very small particles through overclocking oscillation, and then blows water mist into the air through the fan 9, thereby humidifying the air.

[0023] The through groove 3 is wide at the top and narrow at the bottom, and the upper end of the through groove 3 is in contact with the side wall of the top plate 4, and the lower end of the through groove 3 is in contact with the side wall of the filter plate 2, so that the through groove 3 supports the top plate 4.

[0025] Working principle:

[0026] The air filter, which is easy to replace activated carbon, is used by turning on the fan 9, which drives the air below to be discharged upward and forms a negative pressure. The air on the side of the filter plate 2 facing the air inlet 8 is affected by the negative pressure, passes through the filter plate 2 and is discharged upward along the fan 9, thereby achieving air filtration. When the air is relatively dry, the water pump in the water tank 13 can be turned on, and the water pump pumps water into the atomizer 12 along the water pipe 14. The atomizer 12 forms water mist and humidifies the air along with the air flow.

[0027] When the activated carbon filter plate 2 needs to be replaced, the rotating block 16 is rotated until it is separated from the top plate 4, and the spring 10 pushes the pressing plate 11 and the filter plate 2 upward, so that the handle 6 can be lifted upward and the filter plate 2 can be replaced, and the replaced filter plate 2 is inserted downward into the through groove 3. The bottom end of the filter plate 2 presses the pressing plate 11 downward, and the top plate 4 is pressed down into the through groove 3. The torsion spring 17 automatically rotates the rotating block 16 to the top of the top plate 4 and locks it, thus completing the entire use process of the air filter that is easy to replace activated carbon.
