Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0016] Referring to FIGS. (1-5), an air sampler for indoor air detection includes a sampling box 1 and a sampling cylinder 2, characterized in that: a plurality of placement grooves 11 for placing the sampling cylinder 2 are opened at the top of the sampling box 1, the top of the sampling cylinder 2 is open, the inside is hollow, and an intake pipe 23 is provided at the bottom. One end of the intake pipe 23 is communicated with the inside of the sampling cylinder 2, and a pipe cap 4 is spirally installed at the other end. A piston 3 is slidably arranged in the sampling cylinder 2. One end of a connecting rod 32 is rotatably connected to the top of the piston 3, and the other end is fixedly connected to a limiting piece 31. A card slot 13 for the intake pipe 23 and the pipe cap 4 to enter is opened at the bottom of the placement groove 11.
