An embodiment of the present application provides an aerosol-generating device for heating an aerosol substrate in a smokable article to volatilize an aerosol from the aerosol substrate for smoking, the aerosol comprising herbal medicine, nicotine or flavour compounds such as tobacco flavourant. In the embodiment shown in figure 1, the smokable article 1 is a smoking article (e.g. a cigarette, cigar, etc.), but this is not intended to be limiting.

In the embodiment shown in figure 1, the aerosol-generating device comprises a housing and a receiving chamber and a heat generating component 2. A receiving chamber for removably receiving at least part of the smoking article 1 so that the smoking article 1 can be replaced when the aerosol substrate 11 in the smoking article 1 is depleted and a heat generating component 2 for generating heat to cause the smoking article 1 in the receiving chamber to generate a volatile to form a smokable aerosol are both provided in the housing.

Referring to fig. 2 and 3, the heating element 2 includes a heating element 21 and a flange 22, the flange 22 is fixed in the housing and located below the accommodating cavity, so that the heating element 21 can be at least partially located in the accommodating cavity, the heating element 21 is rod-shaped or sheet-shaped or other shapes, and the cross section of the heating element 21 can be asymmetric shapes such as a circle, a straight line, a cross, a triangle, a quadrangle, a hexagon, a starburst shape, and the like, which are symmetric and asymmetric, and is not limited herein. A part of the heat-generating body 21 is fixed to the flange 22 and a part is arranged in the receiving cavity so that when the smokable article 1 is loaded into the receiving cavity, part of the heat-generating body 21 can be inserted inside the smokable article 1 to generate heat in the central region of the smokable article 1 and heat the smokable article 1.

In some embodiments, referring to fig. 4, the heating element 21 has a ceramic housing 211 and a heating element 212 located inside the ceramic housing 211, the heating element 212 is a heat source of the heating element 21 and can generate heat, and then the ceramic housing 211 is heated by heat transfer, the ceramic housing 211 has an effect of isolating the heating element 212 from the smokable product 1, and the heating element 212 is prevented from directly contacting the smokable product 1, so that the smokable product 1 contacting the heating element 212 is prevented from being carbonized due to too high contact temperature, and the taste is not affected. The ceramic case 211 may have a cavity 213 therein for accommodating the heating element 212, so that the heating element 212 may be a heating tube formed by winding a resistive mesh, or may be a spiral coil formed by winding a resistive wire, or may be a heating element 212 formed by filling conductive ceramic or the like in the cavity 213 to generate heat by resistance when energized; the heating element 212 may be made of a magnetic body in which energy loss due to eddy current loss (eddy current loss) and hysteresis loss (hysteresis loss) is generated when a varying magnetic field is applied to the magnetic body, and the lost energy is released from the magnetic body as heat energy. The greater the amplitude or frequency of the changing magnetic field applied to the magnetic body, the more thermal energy can be released from the magnetic body. The magnetic body may include at least one of ferrite (ferrite), ferromagnetic alloy (ferromagnetic alloy), stainless steel (stainless steel), and aluminum (Al). The magnetic material may further contain at least one of a ceramic such as graphite (graphite), molybdenum (molybdenum), silicon carbide (silicon carbide), niobium (niobium), nickel alloy (nickel alloy), metal film (metal film), zirconium dioxide (zirconia), a transition metal such as nickel (Ni) or cobalt (Co), and a metalloid such as boron (B) or phosphorus (P).

In other embodiments, and with reference to FIG. 3, the ceramic material from which the ceramic housing 212 is made is a conductive ceramic that heats when energized. In still other embodiments, the heating element 212 is embedded within the wall of the ceramic shell such that the heating element 212 is closer to the outer surface of the ceramic shell 211, which helps to improve the transfer efficiency of the heating element 212.

In still other embodiments, the heating element 212 is a resistive film formed on the periphery of the ceramic core rod by chemical deposition, physical deposition, spraying or electroplating, and then a ceramic shell 211 is disposed outside the heating element 212 to protect the heating element 212.

In still other embodiments, the heating element 212 includes a resistance heating element or an electromagnetic induction heating element, which is disposed inside the casting sheet by a process such as thick film printing, and then the casting sheet is attached to the outer surface of the ceramic core rod in a curling manner, and the resistance heating element or the electromagnetic induction heating element is located between the casting sheet and the ceramic core rod, and then the heating element 212 and the ceramic core rod are integrated into a single structure by a sintering process, in which case the inside of the ceramic core rod may be hollow, partially hollow, or completely solid, and the casting sheet constitutes the ceramic housing 211. In this embodiment, since the resistance heat generating elements or the electromagnetic induction heat generating elements are difficult to be uniformly distributed on the inner side of the casting sheet, a partial region of the casting sheet may not be covered with the resistance heat generating elements or the electromagnetic induction heat generating elements (for example, an edge region of the casting sheet, there is substantially no distribution of the resistance heat generating elements or the electromagnetic induction heat generating elements, when the casting sheet is wound into a cylindrical shape, a blank region of a larger sheet having no resistance heat generating elements or electromagnetic induction heat generating elements is formed in the vicinity of a joint of the cylindrical casting sheet, and a distribution density of the resistance heat generating elements or the electromagnetic induction heat generating elements is larger in the partial region (for example, a middle region), so that the heat generating body is made to have an uneven temperature distribution at the time of heat generation, the heat amount of the partial region is concentrated, and the temperature of the partial region is lower due to being far from the resistance heat generating elements or the electromagnetic induction heat generating elements, so that the temperature calibration is performed for the heat generating body of this type, temperature sampling needs to be performed on the same position on the heating body.

Referring to fig. 2-4, the ceramic housing 211 includes a tapered introduction portion a, a first portion b, a second portion c, and a fixing portion d, in order from top to bottom along the axial direction, the tapered introduction portion a is substantially tapered, for guiding the insertion of the heating element 21 into the smokeable product 1, the first portion b being connected to the tapered lead-in portion a, the first portion b having at least part of the cavity 213 therein, the heating element 212 being located in the cavity 213 defined by the first portion b, or the heating element 212 is embedded in the wall of the first part b, which is connected to the fixing part d through the second part c, in the case where the heating element 21 is inserted into the smokable product 1 mainly through the tapered introduction portion a and the first portion b, the second portion c and the fixing portion d are exposed outside the smokable product 1, therefore, in order to reduce power consumption, the second portion c may not generate heat from the heating element 212, and the fixing portion d is used for fixing to the flange 22 and mainly functions to fix the heating element 21. It can be seen that the smokable article 1 is free from contact with the flange 22, and the distance between the smokable article 1 and the flange 22 can be the axial length of the second portion c, thereby forming an insulating layer e between the smokable article 1 and the flange 22 for inhibiting heat transfer from the containment chamber to the flange 22, the air entering through the lower end of the smokable article 1, said insulating layer e being capable of preheating the air entering the smokable article 1, further reducing energy consumption.

Referring to fig. 3 and 4, the ceramic housing 211 has a heat conductive coating 214 on at least a part of an outer surface thereof, the heat conductive coating 214 has good heat conductivity, so that the received heat can be rapidly and uniformly distributed, and the heat conductive coating 214 is disposed to improve the heat transfer efficiency of the ceramic housing 211, increase the radiation property of the surface temperature, help to accelerate the volatilization of the aerosol substrate 11, generate a large amount of aerosol smoke, and improve the experience and feeling of a user.

The heat conductive coating 214 used in the present application is made of a mixture, and the overlapping properties of the mixture are utilized to meet the corresponding requirements. Specifically, the main components of the mixture include glass and metal (e.g., silver), and the incorporation of glass in metal or metal in glass can improve the adhesion of metal on the surface of the ceramic housing 211, thereby preventing the heat-conductive coating 214 from falling off or thinning after the smokable article 1 is inserted and pulled out for many times. Meanwhile, metal has high heat transfer efficiency, so that the temperature can be rapidly distributed on the heat-conducting coating 214, and glass has high heat capacity, so that the temperature can be balanced, a temperature field can be balanced, the phenomenon that the local temperature is too high is avoided, and the temperature is uniformly distributed on the heat-conducting coating 214. Moreover, the glass can effectively prevent smoke spots from being retained, and the surface of the heating body 21 can be ensured to be clean.
