Wherein, the first part 31 of the harmful gas adsorption component 30 corresponds to the first air outlet 12, and the second part 32 of the harmful gas adsorption component 30 corresponds to the second air outlet 13, that is, when the wind in the wind channel 10 passes through the first part 31 of the harmful gas adsorption component 30, the first part 31 adsorbs the harmful gas in the gas, the filtered gas can pass through the first air outlet 12 to the indoor, when the wind in the wind channel 10 passes through the second part 32 of the harmful gas adsorption component 30, the harmful gas enriched in the second part 32 can be released, and the released harmful gas and the air can be discharged to the outdoor through the second air outlet 13.
Moreover, the harmful gas adsorption component 30 can rotate in the air duct 10, when the first part 31 of the harmful gas adsorption component 30 adsorbs the harmful gas and tends to saturate, the first part 31 can rotate to the position of the second part 32, and the second part 32 can rotate to the position of the first part 31, at this time, the first part 31 and the second part 32 can change the treatment mode of the harmful gas, the first part 31 can release the harmful gas, the second part 32 adsorbs the harmful gas, when the second part 32 adsorbs the harmful gas and tends to saturate again, the positions of the first part 31 and the second part 32 rotate back, and so on, so that the first part 31 and the second part 32 can adsorb or release the harmful gas in turn, and the harmful gas adsorption component 30 can effectively work for a long time.
As shown in fig. 2 and 7, the harmful gas desorption assembly 40 is disposed between the second portion 32 of the harmful gas adsorption assembly 30 and the fan 20, so that when the wind in the wind tunnel 10 passes through the second portion 32 of the harmful gas adsorption assembly 30, the wind needs to pass through the harmful gas desorption assembly 40 first, the harmful gas desorption assembly 42 can heat the gas and the harmful gas enriched in the second portion 32, so that the harmful gas enriched in the second portion 32 is released, and then the released harmful gas and air can be discharged to the outside through the second wind outlet 13.
When the first portion 31 of the harmful gas adsorbing assembly 30 adsorbs the harmful gas to reach the predetermined value, that is, when the first portion 31 of the harmful gas adsorbing assembly 30 adsorbs the harmful gas and tends to saturate, the harmful gas adsorbing assembly 30 rotates, and at this time, the first portion 31 corresponds to the harmful gas desorbing assembly 40, and the second portion 32 corresponds to the first air outlet 12.
That is to say, the harmful gas desorption assembly 40 is fixed in the air duct 10, and the harmful gas adsorption assembly 30 can rotate relative to the harmful gas desorption assembly 40, when the first part 31 of the harmful gas adsorption assembly 30 adsorbs the harmful gas and tends to saturate, the first part 31 can rotate to the position of the second part 32, and the harmful gas adsorption assembly 30 is always arranged between the position of the second part 32 of the harmful gas adsorption assembly 30 and the fan 20, so the harmful gas adsorption assembly 30 can heat the gas and the harmful gas enriched on the first part 31, release the harmful gas enriched on the first part 31, and then the released harmful gas and air can be discharged outdoors through the second air outlet 13.
In addition, the second part 32 rotates to the position of the first part 31, the harmful gas desorption assembly 40 is not arranged between the position of the first part 31 of the harmful gas adsorption assembly 30 and the fan 20, and the second part 32 releases the harmful gas, at this time, the second part 32 has sufficient capacity of adsorbing the harmful gas, the second part 32 adsorbs the harmful gas in the airflow, and the filtered gas can be introduced into the room through the first air outlet 12. When the second part 32 is saturated again when adsorbing the harmful gas, the positions of the first part 31 and the second part 32 are rotated back, and so on, so that the first part 31 and the second part 32 can adsorb or release the harmful gas alternately.
When the second portion 32 needs to be rotated to the position of the first portion 31, the second portion 32 can be rotated clockwise by 180 °, and when the second portion 32 adsorbs harmful gas and tends to be saturated again, the second portion 32 can be rotated counterclockwise by 180 °, so that the second portion 32 returns to the original position, the rotation mode and the rotation angle of the first portion 31 can be sequentially pushed, and of course, the rotation mode and the rotation angle of the first portion 31 and the second portion 32 can be the same, but are not limited thereto.
From this, through rotationally setting up harmful gas adsorption component 30 in wind channel 10, harmful gas adsorption component 30 rotates the back in addition, and harmful gas adsorption component 30's first portion 31 and second portion 32 can the switching position each other, and first portion 31 and second portion 32 can adsorb or release harmful gas in turn like this to can guarantee that harmful gas adsorption component 30 can continuously and stably operate, also can keep harmful gas adsorption component 30 to get rid of harmful gas effectively for a long time.
