Heating and atomizing device

The invention discloses a heating and atomizing device. The device comprises a shell; the shell comprises an air inlet and an air outlet, wherein a heating chamber is arranged in the shell, and an air flue is formed by the connection of the air inlet, the heating chamber and the air outlet; the heating chamber is filled with an atomizing material, a heat conductor of which one surface is closely propped against the atomizing material is arranged in the atomizing material, and the heat conductor is heated by an electric heating device. The heating and atomizing device provided by the invention has the advantages of heating the atomizing material from inside to outside quickly in an energy-saving way, so as to generate the smog of which the taste is close to that of the burnt atomizing material.
