Detailed implementation manners

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0022] In this embodiment, the moving component includes a plurality of universal wheels 3, the universal wheels 3 are fixed to the lower side of the base 1, a push handle 2 is fixed to one side of the base 1, the base 1 can be pushed through the push handle 2, and the base 1 moves through the universal wheels 3, so that the device can be moved to the position to be tested.

[0023] The telescopic component includes a telescopic rod 4, one end of the telescopic rod 4 is fixedly connected to the base 1, the other end of the telescopic rod 4 is fixedly connected to the protective shell 5, the telescopic rod 4 includes a first rod body 401 and a second rod body 402, the first rod body 401 is slidably connected to the second rod body 402, and one end of the first rod body 401 is threadedly engaged with a positioning bolt 403, and the positioning bolt 403 is in contact with the second rod body 402.

[0024] Specifically, the second rod body 402 can be slid, so that the second rod body 402 slides out of the first rod body 401 upward, so as to adjust the height of the hot smoke generator 6, and then rotate the positioning bolt 403, so that the positioning bolt 403 presses the second rod body 402, thereby fixing the second rod body 402, and the height of the hot smoke generator 6 can be fixed.

[0025] The first cylinder body 701 is communicated with the protective shell 5, the first cylinder body 701 is fixedly connected to the protective shell 5, the smoke outlet of the hot smoke generator 6 corresponds to the first cylinder body 701, the inclined cylinder 703 is fixed between the first cylinder body 701 and the second cylinder body 702, the collection box 704 is fixedly connected to the inclined cylinder 703 by threads, the shielding component includes a baffle plate 8, the baffle plate 8 is a conical structure, and the baffle plate 8 is fixedly connected to the second cylinder body 702.
