Abstract: A cigarette heater, comprising a heating assembly and a heat insulation assembly used for insulating the heating assembly; the heating assembly comprises a longitudinal heating cavity used for accommodating a cigarette and a heating body used for heating the cigarette; the heat insulation assembly comprises an anisotropic material layer sleeved outside the heating assembly, the thermal conductivity coefficient of the anisotropic material layer in the radial direction being lower than the thermal conductivity coefficient thereof in the axial direction, being used for reducing the thermal conduction of the heat in the heating cavity along the radial direction toward the periphery. By means of arranging the anisotropic material layer outside the heating assembly, the present cigarette heater isolates the heat transfer in the radial direction and also converts the direction of conduction to a dispersed transfer toward the axial direction, reducing the radially outward heat transfer.
