As shown in fig. 1-2, the outer walls of the two activated carbon adsorption plates 51 are connected with the inner wall of the housing 3 through the elastic buffer member 52, and when the return air is applied to the activated carbon adsorption plates 51 again, the activated carbon adsorption plates 51 are slightly vibrated, especially the left activated carbon adsorption plate 51 is subjected to upward airflow, and the right activated carbon adsorption plate is subjected to downward airflow, so that the whole activated carbon adsorption plate generates an inclined vibration effect.
Under the action of the intermittent ventilation mechanism 721, the two activated carbon adsorption plates vibrate reciprocally, so that the aggregation of adsorption particles in the activated carbon adsorption plates is reduced, the service cycle of the activated carbon adsorption plates is prolonged, and the air purifying effect is enhanced.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
