The sleeve 11 is heated by induction heating of the electromagnetic induction coil 12, since the cross-sectional area of the first sleeve 111 is smaller than that of the second sleeve 112 along the transverse axis, and the second sleeve 112 has a bigger mass than the first sleeve 111, according to a heat quantity calculation formula: Q=c*m*ΔT, of which, c is the specific heat capacity, m is the mass, ΔT is the changing temperature and Q is the heat quantity; and a power calculation formula: P=W/t, of which, P is the electric power, W is the electric work, t is the time, presuming the energy conversion efficiency η is Q=W*η, then P*t=c*m*ΔT*η, therefore, when P is a constant, objects with same materials that have same specific heat capacity, if the object has bigger mass m, then the object need more time to rise to a same temperature. Therefore, during heating the sleeve 11, since the second sleeve 112 has a bigger mass than the first sleeve 111, the first sleeve 11 needs less time to rise to a preset temperature, but the second sleeve 112 needs more time to rise to the preset temperature, which may realize the segment heating.
An insulating layer (not shown) encircles outside the sleeve 11, configured for making less heat of the sleeve 11 delivered to outside. The insulating layer is made from thermal insulation materials, such as, thermal insulation glue, aerogel, asbestos, aluminum silicate and calcium silicate etc. The insulating layer may further improve thermal efficiency and heat preservation effect, making the heating rate faster.
The sleeve 11 has a tobacco receptacle 110 for receiving the solid tobacco materials. For example, the solid tobacco materials is at least one or more selected from a group of tobacco shreds, tobacco sheets, tobacco powders and tobacco rods.
In some embodiment, it makes sense that the first sleeve 111 and second sleeve 112 are both made from same metallic magnetic materials or different metallic magnetic materials, such as the first sleeve 111 and the second sleeve 112 are both made from a conductor A, or the first sleeve 111 is made from the conductor A and the second sleeve 112 is made from a conductor B. When the first sleeve 111 and the second sleeve 112 are made from different metallic magnetic materials, the first sleeve 111 has a larger magnetic permeability than the second sleeve 112, so when the electromagnetic induction coil 12 heats the sleeve 11, the first sleeve 111 generates larger amount of heat than the second sleeve 112, therefore realizing segment heating.
In some embodiment, it makes sense that the cross-section of the sleeve 11 is shaped as square, rectangular or irregular quadrilateral etc. just to guarantee that the sleeve 11 is able to receive the solid vaporizable materials and the second sleeve 112 has a bigger mass than the first sleeve 111.
In some embodiment, the sleeve 111 is a hollow body, the cross-sectional area refers to entity part of the body, such as, if the sleeve 11 is a hollow cylinder, the cross-section is a annular, so cross-sectional area is the area of the annular.

The electromagnetic induction coil 12 includes a first interface 121 and a second interface 122; the first interface 121 and the second interface 122 are coupled with the power supply module 13 configured for supplying power to the electromagnetic induction coil 12, so the electromagnetic induction coil 12 generates the electromagnetic induction. Based on the electromagnetic induction law, when the electromagnetic induction coil 12 is electrified with the alternative current, the electromagnetic induction coil 12 generates alternative magnetic flux inside, the alternative magnetic flux generates induced potential inside the sleeve 11, meanwhile when magnetic lines of force in the magnetic field passes through the sleeve 11, the alternative magnetic lines of force forms a loop inside the sleeve 11, and the cross-sectional area of the sleeve 11 generates the inductive current, that is vortex, for heating the sleeve 11.
In some embodiment, it makes sense that the electromagnetic induction coil 12 is able to extend into the tobacco receptacle 110, or be embedded inside of the first sleeve 111, just to guarantee that the first sleeve 111 is inducted by the magnetic field to generate heat. In other embodiments, the number of the electromagnetic induction coils 12 is two, including a first coil and a second coil (not shown). The first coil and the second coil both encircle outside the first sleeve 111, the first coil and the second coil may have different turns of coil to change the heating rate of the sleeve 11, which is more flexible to adjust the heating effect.
In some embodiment, it makes sense that the number of turns of the electromagnetic induction coils 12 may be more than or less than the length of the first sleeve 111, the number may be determined by the cross-sectional area of the electromagnetic induction coils 12 and the cross-sectional area of the first sleeve 111.
In some embodiment, it makes sense that an insulating layer is coated to the electromagnetic induction coil 12, configured for preventing leakage of electricity of the electromagnetic induction coil 12. The insulating layer is made by insulating materials such as, synthetic resin, epoxy resin, phenolic resin, 4250-plastic and polyimide plastic etc.

In terms of the vaporizer 10 in the present disclosure, the second sleeve 112 has a bigger mass than the first sleeve 111, a cross-sectional area of the first sleeve 111 is smaller than that of the second sleeve 112 along the transverse axis, that means, that increasing rate of temperature of the second sleeve 112 is slower than that of the first sleeve 111, therefore, the segment heating of the vaporizer 10 is realized, enabling consistent flavor during smoking, improving user experience and reducing the cost.
In the embodiments, the sleeve 11 is a nearly hollow cylinder, for receiving the vaporizer 10. The housing 20 may be a plastic housing, made of some heat preservation materials such as polycarbonate, polyurethane and polyimide etc. In other embodiments, the housing 20 may be made of metallic, coating plastic film on the housing 20 to achieve the heat preservation effect.
