In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of maintenance, cleaning be convenient to, and can not influence the ventilating fan that has front shroud of indoor environment integrity simultaneously.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of ventilating fan comprises air guide sleeve, is positioned at the motor and the flabellum of air guide sleeve, and described air guide sleeve front surface is movably installed with front shroud.

As the utility model most preferred embodiment, described front shroud is the retractable door that connects with described air guide sleeve on one side, and the free end of described retractable door is equipped with knocker.

As the further improvement to above-mentioned mode of execution, described front shroud is the bivalve door by the fixing relative folding of hinge.

The beneficial effects of the utility model are: because the utility model is equipped with front shroud at the surface activity that air guide sleeve is positioned at indoor part, like this when ventilating fan is static, to behind the front shroud fastening indoor and outdoor surroundings be separated fully, prevent in mosquitos and flies and the outdoor dirt inlet chamber, and front shroud has also hidden contaminated flabellum simultaneously, so can make whole indoor environment more neat, when on front shroud, being painted with pattern, also can play the effect of beautifying the environment, as long as just can realize the exhaust cooking-fume discharging and open front shroud when using, the function of ventilation, and because front shroud is positioned at indoor, so it is all very convenient when keeping in repair or cleaning, because front shroud is not in the exhaust passage in the exhaust process, so reduced contaminated chance, long-time use also can keep the front shroud clean hygiene.
