The clamping portion 20 is movably arranged on the exhaust housing 10, and the clamping portion 20 has a clamping position and an avoidance position. When the clamping portion 20 is in the clamping position, the clamping portion 20 is clamped with the part to be connected, so that the exhaust device 90 is arranged on the part to be connected. When the clamping portion 20 is in the avoidance position, the clamping portion 20 avoids the part to be connected, so that the exhaust device 90 is separated from the part to be connected.

[0036] By using the exhaust device 90 provided in this embodiment, the air filtered by the exhaust device 90 will be blown out obliquely upward through the exhaust port to prevent the air discharged from the exhaust port from blowing toward the ground, thereby avoiding dust and keeping the exhaust away from the user, thereby improving the comfort of use. At the same time, by moving the clamping portion 20 to the clamping position, the clamping portion 20 can be clamped with the part to be connected, so that the exhaust device 90 is connected to the part to be connected. By moving the clamping portion 20 to the avoidance position, the clamping portion 20 can be disengaged from the part to be connected, thereby separating the exhaust device 90 from the part to be connected, thereby facilitating the user to disassemble and assemble.
