Indoor air pollution prevention system

An indoor air pollution prevention system comprising:

• at least one indoor field unit, wherein the indoor field unit is a space surrounded and isolated by a plurality of partitions;
• a gas exchange device exchanging indoor gas and outdoor gas, and comprising at least one intake channel and at least one exhaust channel, wherein the intake channel and the exhaust channel are communicated to the indoor field unit, the intake channel is constructed in the indoor field unit for inhaling the outdoor gas, and the exhaust channel is constructed in the indoor field unit for discharging the indoor gas;
• an intake filter device embedded at one port position where the intake channel is communicated and constructed in the partition of the indoor field unit, wherein the intake filter device comprises at least one fan, at least one filter element and a gate, wherein when the fan is activated and the gate is opened at the same time, the outdoor gas in the intake channel is guided by the fan, to pass through the filter element for filtration and removal and enter the indoor field unit;
• an exhaust filter device embedded at one port position where the exhaust channel is communicated and constructed in the partition of the indoor field unit, wherein the exhaust filter device comprises at least one fan, at least one filter element and a gate, wherein when the fan is activated and the gate is opened at the same time, the indoor gas in the indoor field unit is guided by the fan, to enter the exhaust channel, pass through the filter element for filtration and removal and be discharged out;
• a plurality of gas detectors disposed in each of the indoor field unit for detecting a characteristic, a concentration and a location of an air pollution, and outputting to form air pollution data;
• and
• a cloud computing service device, receiving the air pollution data detected in each of the indoor field unit, storing the air pollution data in an air pollution database, implementing an artificial intelligence calculation to determine the location of the air pollution, and issuing a control command to the indoor field unit with the air pollution generated, wherein an activation operation of the fan of the exhaust filter device in the indoor field unit is controlled, and the gate is opened at the same time, whereby a directional airflow is generated, and the air pollution in the indoor field unit is guided quickly to the filter element of the exhaust filter device for filtering and removal, so that the air pollution in the indoor field unit is cleaned to reach a gas state of complete purification.
