This mobile indoor air detection device can conveniently purify the air after detection, reduce harmful components in the air, and improve the health of indoor people. Moreover, each filter and movable drawer are connected by a card block, so the filter and drawer can be removed, which is convenient for cleaning and replacing the filter and activated carbon. The sealing mechanism can better increase the sealing effect and reduce air leakage. Secondly, the external air can be concentrated, and the detector probe is perpendicular to the lowest end of the top speaker cover, which can increase the close contact effect between the detector probe and the air and improve the quality of air detection. According to the above, although the air detector can be used well, it is usually not convenient to adjust the height and angle of the air detector body as needed, and it is difficult to perform all-round detection of indoor air, which in turn affects its detection effect and often troubles people.
