Ambient air detection sampling tool

The utility model relates to an ambient air detection sampling tool which comprises a bottle body and a cover body, a connector used for being connected with an air pump is arranged on the side wall of the bottom of the bottle body, and a valve used for opening or closing the connector is arranged on the connector. The cover body covers the upper part of the bottle body; a plurality of windows for sampling gas to enter are annularly distributed in the position, corresponding to the middle of the side wall of the cover body, of the side wall of the upper part of the bottle body, and the windows can be used for filtering the sampling gas twice. The utility model has the beneficial effects that a plurality of windows can be arranged for sampling, and the sampling speed is accelerated, so that the whole sampling time is shortened; the sampled gas horizontally passes through the filter screen and then is collected, and compared with a mode that the sampled gas passes through the filter screen up and down, dust par
