It is further arranged to：The madial wall of the air inlet duct is installed with the first connecting cavity and the second connecting cavity respectively, described Several heating tubes for crossing air inlet duct are communicated between first connecting cavity and the second connecting cavity, the fever cavity is connect with first Heat outlet pipe is communicated between chamber, second connecting cavity is equipped with air outlet.

By using above-mentioned technical proposal, the heat to generate heat in cavity is conducted by heat outlet pipe to the first connecting cavity, Heat is conducted to several heating tubes by the first connecting cavity so that air-flow can also reach the effect of heating when flowing through air inlet duct Fruit；By the cooperation between heating tube, heating cavity and heating coil three, three heating are realized to air-flow, are made multi-functional Heater can reach better heating effect, and from the air-flow flowed out in heating tube then by after the second connecting cavity from air outlet stream Go out.

It is further arranged to：The free end of the heat inlet tube is installed with connecting plate.

By using above-mentioned technical proposal, the setting of connecting plate enables heat inlet tube to facilitate and connects with the realization of pyrotoxin body It connects, the easy installation operation of worker.

It is further arranged to：The port of the air inlet duct and the port of exhaust passage are flared setting.

By using above-mentioned technical proposal, being flared the mode of setting can enable what air-flow more concentrated to be flowed towards cavity It is dynamic, when air-flow by exhaust passage when being flowed outwardly, can to external diffusion more uniformly.

In conclusion the utility model has the advantages that：The utility model by generate heat cavity, heating coil with And the combination between heating tube three, it can realize that air-flow realizes preferably heating, to reach better heating effect.
