Through setting up filter screen 471 for the outdoor new trend that gets into in the new trend casing 41, in the indoor environment is input again to after the filter screen 471 filters, further promotes the air quality of indoor environment.

The total amount of dust that can be adsorbed by the filter screen 471 is limited due to its characteristics. When the diameter of the dust and foreign matter is limited to the upper limit (such as flying insects, cotton, leaves, etc.) of the diameter of the super-filter screen 471, or the dust holding capacity of the filter screen 471 reaches the upper limit, the dust and foreign matter cannot be adsorbed by the filter screen, and then can be collected on the air inlet side of the filter screen.

In order to maintain the normal filtering function of the filter screen, the user needs to replace the filter screen at regular time. In the prior art, the fresh air module 4 can only filter fresh air through a filter screen, and cannot realize a dust collection function. When the user takes out the filter screen and changes it, dust, the foreign matter of gathering in filter screen air inlet side are extremely easy to spill on the user and cause bad user experience on one's body, and dust foreign matter gathers inside fresh air module 4 simultaneously, can't clean up, and after changing new filter screen, the dust in the fresh air module 4 can the secondary adsorb on the new filter screen, influences the life of new filter screen, and user experience sense is extremely poor.
