[0026] The working principle and use process of the present invention are as follows: when in use, the power supply of the negative pressure fan 62 is turned on, and the negative pressure fan 62 draws air outside the building and blows it into the building. In this process, the air is initially filtered and dusted by the detachable dust cover 74, the air is adsorbed and purified by the activated carbon adsorption plate 71, and the air is secondary dusted by the second protective filter 73, thereby achieving full dust removal and purification of the air and preventing harmful gases from entering the building. When the intelligent controller 1 detects that the indoor air is dry and needs to be humidified, the intelligent controller 1 turns on the power of the semiconductor refrigeration sheet 594 and the heat dissipation fan 593, and quickly and efficiently cools the coolant 595 through the semiconductor refrigeration sheet 594, so that the temperature of the first hollow liquid storage tank 596, the second hollow liquid storage tank 597, the hollow heat-conducting metal pipe 54 and the second heat-conducting metal fin 598 are all quickly reduced. At this time, the moisture in the outdoor air of the building quickly condenses into water droplets on the hollow heat-conducting metal pipe 54 and the second heat-conducting metal fin 598, and then controls the telescopic height adjustment member 57 to extend, so that the hollow heat-conducting metal pipe 54 moves downward. At this time, the second hollow storage tank 596 is used to cool the coolant 595. The liquid tank 597 seals the top of the electric drying tube 55. At the same time, the airflow of the negative pressure fan 62 quickly dries the water droplets on the surface of the hollow heat-conducting metal tube 54, the second heat-conducting metal fin 598 and the first hollow liquid storage tank 596, so that the moisture on the surface of the hollow heat-conducting metal tube 54, the second heat-conducting metal fin 598 and the first hollow liquid storage tank 596 is transferred to the building room with the air flow, thereby increasing the humidity in the building room. Therefore, the use of the second heat-conducting metal fin 598 significantly increases the humidification speed of the device. In addition, the user can heat the blown cold air through the detachable electric heating element 3, thereby realizing the correction and adjustment of the blowing temperature; Therefore, when the telescopic height adjustment member 57 is retracted, the moisture outside the building is condensed into water droplets through the cooperation of the first hollow liquid storage tank 596, the second hollow liquid storage tank 597, the hollow heat-conducting metal tube 54 and the second heat-conducting metal fin 598. When the telescopic height adjustment member 57 is extended, the moisture on the surfaces of the first hollow liquid storage tank 596, the second hollow liquid storage tank 597, the hollow heat-conducting metal tube 54 and the second heat-conducting metal fin 598 is transferred to the interior of the building. By controlling the continuous extension and contraction of the telescopic height adjustment member 57, the humidity inside the building is rapidly increased. When humidification is completed, the power supply of the electric drying tube 55 is turned on, and the surfaces of the first hollow liquid storage tank 596, the second hollow liquid storage tank 597, the hollow heat-conducting metal tube 54 and the second heat-conducting metal fin 598 are rapidly dried by the electric drying tube 55 to avoid the internal growth of bacteria in the device due to humidity, thereby fundamentally solving the problem of indoor air being polluted during humidification due to the internal growth of bacteria in the device. Therefore, through the mutual cooperation of multiple structures, the ventilation and filtering device can collect moisture in the outdoor air of the building, thereby realizing the regulation of the indoor humidity of the building without artificial water supply, thereby effectively solving the problem of safety hazards in the ventilation and filtering device caused by bacteria breeding when water is stored. Secondly, the present invention is easy to maintain and repair, and the present invention has a simple structure, is easy to use and environmentally friendly, and is worthy of promotion and use.
