Fig. 1 is a schematic view of the internal structure of a cartridge according to an embodiment of the present invention. As shown in fig. 1, the present embodiment includes a wrapper 12 wrapping a smoking material 11 to form a columnar structure. Fig. 3 is a schematic structural diagram of a metal heating element according to an embodiment of the present invention, wherein the metal heating element 13 includes a central metal piece 13a and a plurality of fin-shaped metal pieces 13b, and the metal heating element 13 is also disposed in the wrapper 12 and is wrapped by the wrapper 12 together with the smoking material 11. The central metal element of the metal heating element is axially arranged along the wrapper, and the fin-shaped metal element 13b extends from the central metal element 13a towards the side wall of the cartridge 10.

According to the embodiment of the embodiment, the position of the metal heating part 13 in the cigarette cartridge can be more stable, and the metal heating part 13 in the cigarette cartridge is prevented from falling off from the cigarette cartridge 10 in the transportation link and the use link of the product. Meanwhile, the plurality of fin-shaped metal pieces 13b distributed along the central metal piece 13a are utilized to realize the full contact between the metal heating piece 13 and the tobacco 11, so that the tobacco in the cartridge 10 can be integrally heated during heating, the excessive heating of the tobacco 11 close to the heating piece is avoided, the tobacco 11 far away from the heating piece is not heated in place, and the mouthfeel of a smoker is kept consistent before and after the smoker sucks the cigarette.

In some embodiments, the fin-shaped metal piece 13b may be wire-shaped or sheet-shaped, and when the sheet-shaped fin-shaped metal piece 13b is arranged with the plane side disposed perpendicular to the axial direction of the cartridge 10, the play of the metal heating member 13 may be avoided to the maximum extent while reducing the falling of the smoking material from the cartridge 10. The bending strength in the axial direction of the cartridge can be increased when the laminar fin-shaped metal members are arranged along the central metal member.

When the fin-shaped metal piece is in a filament shape, different densification degrees can be selected in different areas of the cartridge. If the middle part of the smoke cartridge is arranged loosely, the smoke cartridge is arranged more compactly close to the two ends of the smoke cartridge, so that the smoke material can be better fixed.

Further, the metal heating member 13 is iron, cobalt, nickel, or an alloy containing at least one of them. The metal has strong oxidation resistance and high heating temperature, is easy to form vortex and instantly generates a large amount of heat.

Further, the tobacco material 11 may be cut tobacco, tobacco leaf or tobacco powder. When the tobacco material is cut tobacco and the fin-shaped metal piece is of a filamentous structure, the cut tobacco can be arranged around the central metal piece 13a in a surrounding manner, and the cut tobacco and the fin-shaped metal piece 13b are arranged approximately vertically, so that the cut tobacco can be effectively prevented from falling off in the using process of the cigarette cartridge.

When the tobacco material is tobacco powder, the fin-shaped metal piece 13b can be preferably in a sheet shape, the plane side of the fin-shaped metal piece is perpendicular to the axial direction of the cigarette cartridge, or the fin-shaped metal piece is in a more compact form and is arranged at the two ends of the cigarette cartridge, so that the tobacco powder can be better fixed.

Further, the fin-shaped metal member 13b may be connected to the central metal member 13a in a flocked manner using a flocker. When the central metal piece is thick, a stud head hair-planting machine can be selected, firstly, hair-planting holes are machined in the central metal piece 13a, then, the filiform wing-shaped metal piece 13b is formed into a U shape and is fastened, then, the hair-planting holes are implanted, and the locking effect is achieved through deformation and expansion of the iron wire.

When the central metal member 13 is a thin wire, two metal wires may be combined into a group, which are respectively bent into a U shape, and the group is sleeved on the central metal member in an intersecting manner, and then the ends of the two metal wires are reversely pulled and twisted in opposite directions, thereby being fixed on the central metal member 13. Finally, the wire is trimmed to the size of the interior space of the cartridge 10. The fin-shaped metal piece 13b and the central metal piece 13a can be connected with each other more tightly and are not easy to loosen by using the hair planting machine.

Further, a fin-shaped metal piece 13b is arranged around the central metal piece. In addition to the straight extension from the central metal member 13a to the wrapper 12 as shown in fig. 3, the fin-shaped metal member 13b may be arranged around the central metal member 13a in a clockwise or counterclockwise direction from the central metal member 13a, in such a way that the length of the fin-shaped metal member is extended to a certain extent, thereby further increasing the contact area with the smoke.

Further, a filter 14 is provided at one end of the cartridge to filter impurities from the tobacco material. For the non-combustion type electronic cigarette, the temperature is lower than that of the traditional cigarette, and in order to keep the temperature of smoke during inhalation, heat-insulating materials such as porous foam materials, porous aerogel and ceramic materials can be arranged in the outer layer of the filter tip, so that the inhalation mouthfeel is improved.

Further, the wrapper 12 is paper, textile or tobacco. The wrapping material 12 of the non-combustible electronic cigarette can be made of various materials, one of the materials is tobacco leaves, the effect is similar to that of a cigar coat, and the effects of increasing the taste of a smoker and improving the aesthetic feeling of a cigarette bullet are achieved. To further maintain the temperature of the tobacco material 11 in the cartridge 10, the wrapper 12 may be made of a textile type material that is more heat insulating, and when the cartridge temperature reaches a given value, the cartridge 10 may be kept warm for a longer period of time, particularly in cold outdoor environments, after the heating device stops heating, thereby reducing the consumption of electricity.

In an alternative implementation, the embodiment of the present invention further provides an aerosol generating device, which includes an induction coil 20, a control circuit 21 for supplying an alternating current, and the cartridge 10 of the above embodiment. Fig. 2 is a schematic structural diagram of an aerosol-generating device according to an embodiment of the utility model. As shown in fig. 2, when a smoker uses the electronic cigarette, the smoker puts the cigarette into the induction coil 20, and the alternating current supplied by the control circuit 21 causes the induction coil 20 to generate an alternating magnetic field, thereby heating the cigarette.

Alternating current generated by the induction heating power supply passes through the coil to generate an alternating magnetic field, the magnetic conductive object cuts alternating magnetic lines of force therein, so that eddy current is generated inside the object, the eddy current enables atoms inside the object to move irregularly at a high speed, and the effect of heating the metal heating part is achieved. Electromagnetic ovens, electromagnetic rice cookers and the like manufactured by utilizing the electromagnetic induction heating principle are widely used in life.
