Description
Technical field
The present invention relates to a kind of filtering type induced-draft fan, be used for outdoor barbecue and use.
Background technology
Present most a slap-bang shop carries out outdoor barbecue usually in summer, and is full of smoke, and environment has on every side been caused very big pollution.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of filtering type induced-draft fan, and is not only simple in structure, and environment purification.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of filtering type induced-draft fan comprises petticoat pipe and ventilating fan, described petticoat pipe is equipped with ventilating fan in the top, the top of ventilating fan is equipped with ventilative box, and there is crooked passage at the center of ventilative box, in ventilative box look both sides air-vent is arranged, the sponge that contains water is placed in the top of air-vent, activated charcoal is equipped with on top at ventilative box, in the side of petticoat pipe, and the relevant position of activated charcoal, having one to extract mouth out, is the gas outlet on petticoat pipe.
Ventilative box of two covers and sponge are arranged in the described petticoat pipe, and activated charcoal is between the ventilative box of two covers.
This filtering type induced-draft fan adopts ventilative box and contains the sponge of water, can effectively adsorb the pernicious gas in the cigarette, and then further adsorb flue dust by activated charcoal, discharges from the gas outlet through the flue dust that filters.Ventilative box of two covers and sponge are arranged in petticoat pipe, and when activated charcoal was breathed freely between the box at two covers, filter effect was better.
