The indoor air sampler provided by the utility model has the advantages that the controller is operated, and the electric control is sequentially carried out, so that the multipoint sampling can be realized, and the operation is more convenient and faster compared with the prior art.

Further, the bottom of base is connected with driving motor driven gyro wheel, driving motor electricity connection controller. When other points need to be sampled, the controller is directly operated, so that the driving motor is started, the base can be driven to a corresponding position through the rotation of the roller, and the manual carrying is avoided.

Further, the air suction pipe vertically extends upwards, and an arc-shaped filter screen is arranged at the top end of the air suction pipe. Avoid dust etc. to enter into in the breathing tube, influence the detection effect.

Furthermore, the air suction pipe is formed by connecting a plurality of sections of short pipes which are sleeved with each other. The suction pipe can be extended or shortened as required to facilitate the sampling of multiple heights in the chamber.

Further, the quantity of sampling bottle is 3 ~ 10, and a plurality of sampling bottles all with cyclic annular gas-supply pipe threaded connection and equipartition are outside at cyclic annular gas-supply pipe. The number of the sampling bottles is set as required, and the sampling bottles are connected with the annular gas conveying pipe through threads, so that the sampling bottles can be conveniently detached for detection.

Further, be provided with the arc layer board that is used for placing the sample bottle on the base.
