Exhaust device of building material incombustibility test furnace

The utility model relates to an exhaust device of a building material incombustibility test furnace, and belongs to the technical field of building material incombustibility test furnace tests, the exhaust device comprises an exhaust fan and a mounting mechanism, an outlet of the exhaust fan is communicated with an air outlet pipe, the air outlet pipe is communicated with the outside, and the mounting mechanism is arranged on a wall body in a cabin and used for mounting the exhaust fan on the wall body. When the non-combustibility test furnace finishes one test, the exhaust fan is started, and the exhaust fan exhausts the smell in the cabin to the outside, so that the smell in the cabin is quickly weakened, the interval time of the subsequent combustion test of the building material is shortened, and the detection efficiency of the building material is improved. 本申请涉及一种建材不燃性试验炉的排气装置，属于建材不燃性试验炉试验的技术领域，其包括抽风机和安装机构，所述抽风机出口连通有出气管，所述出气管与外界连通，所述安装机构设置于小屋内的墙体上，用于将抽风机安装于墙体上。当不燃性试验炉做完一次试验后，启动抽风机，抽风机将小屋内的气味抽至外界，从而使得小屋内
