DETAILED DESCRIPTION

[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0025] like Figure 1-Figure 6 As shown, the waste gas collection device provided in this embodiment includes a second box body 2, and a box cover 3 movably mounted on the top of the second box body 2, an electric telescopic rod 8 is installed at the bottom of the inner wall of the second box body 2, a mounting plate 9 is provided above the electric telescopic rod 8, a gas collecting bottle 10 is movably mounted on the mounting plate 9, an air inlet pipe 5 penetrating the box cover 3 is installed at the top of the gas collecting bottle 10, and a piston 11 slidably mounted inside the gas collecting bottle 10 is installed at the movable end of the electric telescopic rod 8. Through the arrangement of the electric telescopic rod 8 and the piston 11, the piston 11 can be driven to move by the electric telescopic rod 8, so that the external waste gas is drawn into the inside of the gas collecting bottle 10 through the air inlet pipe 5, without the need for manual operation by the staff, and is simple and convenient to use, which can effectively prevent the staff from inhaling the waste gas at the sampling site.

[0026] The first box body 1 is arranged outside the second box body 2, and the second box body 2 is slidably mounted inside the first box body 1.
