Formaldehyde detection alarm device based on indoor air detection

The utility model discloses a formaldehyde detection alarm device based on indoor air detection. The formaldehyde detection alarm device comprises a mounting base, an induced draft fan and a formaldehyde detector. The beneficial effects of the detection device are that the suckers are fixedly installed at the four corners of the lower surface of the installation pedestal, the detection device is convenient to install, the later displacement is also convenient, and the heat dissipation grooves are fixedly arranged on the outer side wall of the detection device housing, so that the interior of the detection device housing can be subjected to heat dissipation, and the detection efficiency is improved. The damage of high temperature to internal elements of the formaldehyde detector is avoided; according to the formaldehyde detector, the induced draft fan, the air inlet two-way pipeline, the air inlet pipe and the air collecting cover are arranged, when the formaldehyde detector is used, indoor air enters the form
