Rainproof smoke outlet of roof smoke exhaust fan
The invention discloses a rainproof smoke outlet of a roof smoke exhaust fan. The rainproof smoke outlet comprises a smoke exhaust pipe; the smoke exhaust pipe is provided with a connector; the tail end of the smoke exhaust pipe is provided with a cavity; the top part of the cavity is provided with a cover body; the cover body is elastically connected with the cavity through a spring; the cover body is made of an aluminum sheet; the surface of the cover body is plated with a layer of zinc. As the body of the rainproof smoke outlet of the roof smoke exhaust fan, disclosed by the invention, is provided with the cavity, the top part of the cavity is provided with the cover body, and the cover body is elastically connected with the cavity through the spring, when the smoke exhaust fan starts to work, internal airflow thrusts aside the cover body to exhaust smoke, when the smoke exhaust fan does not work, the cover body covers the cavity under the action of the spring, and outside rain cannot enter the cavity in the sleety weather, and therefore the rain-resistance ability of the smoke outlet of the roof smoke exhaust fan is greatly improved.
