Furthermore, a filter is arranged in the fan and close to the air inlet of the fan.

The filter can absorb harmful gas, cannot be directly discharged into the atmosphere when harmful gas exists indoors, and can be discharged into the atmosphere after being absorbed and filtered by the filter, so that the purpose of protecting the environment is achieved; secondly when first flow control valve is unusual, the filter can reduce the speed of outdoor dirty gas to the return air duct backward flow, effectively filters the backward flow gas simultaneously, guarantees that the air is clean pollution-free in the return air duct.

Further, an exhaust device with air conditioner return stack intercommunication still includes: and the second flow control valve is detachably mounted on the air return pipe of the air conditioner and is positioned between the air conditioner and the first exhaust pipe.

The beneficial effect who adopts above-mentioned technical scheme to produce is that, the aperture of second flow control valve comes the suitable regulation according to the aperture of first flow control valve, and first flow control valve aperture increases when a large amount of exhaust of needs, and the second flow control valve aperture reduces to reduce return air inflow air conditioner flow, increase the amount of wind of airing exhaust.

Furthermore, the first flow control valve and the second flow control valve are detachably connected with the corresponding second exhaust pipe and the air conditioner return air pipe respectively through first flange plates.

Adopt the beneficial effect that above-mentioned technical scheme produced to be, it is more convenient with the dismantlement through the ring flange installation, for threaded connection is difficult for leaking moreover, the leakproofness is good.

Furthermore, the air inlet of the first exhaust pipe is connected with the air return pipe of the air conditioner in a detachable mode through a second flange plate or in a welded mode.

The flange plate has the beneficial effects that the flange plate is convenient for mounting and dismounting the first flow control valve and the second flow control valve, and the replacement is more convenient.

Furthermore, the first exhaust duct and the second exhaust duct are made of stainless steel.

The stainless steel welding rod has the beneficial effects that the stainless steel surface has high smoothness, dust and impurities are not easy to accumulate, and the stainless steel welding rod is corrosion-resistant, high-temperature-resistant and oxidation-resistant and has good welding performance.
