The embodiment of the present disclosure relates to the technical field of heating nonburning smoking sets, and in particular to an aerosol generating device.
Tobacco products (e.g., cigarettes, cigars, etc.) are burning tobaccos to produce tobacco smoke during use. People attempt to make products that release compounds without burning so as to replace these tobacco products burning tobaccos.
An example of this kind of products is a heating device, which heats rather than burns a material to release compounds, for example, the material may be a tobacco product or other non-tobacco products which may contain or not contain nicotine. As another example, there exists an infrared heating device which heats a tobacco product through infrared radiation so that the tobacco product releases a compound to generate an aerosol. For example, the patent No. 201821350103.0 of a known technology provides a heating device structure in which a nano far infrared coating and a conductive coating are formed in turn on an outer surface of a quartz tube, wherein the conductive coating is connected to a power source configured to supply power, so that the nano far infrared coating itself generates heat under the supply of power and at the same time forms electron transition to generate infrared rays which then radiate onto the tobacco product within the quartz tube to heat the tobacco product.
During the implementation of the above device, the conductive coating is printed on the nano far infrared coating, there exists a problem of insufficient adhesion and bonding in the overlapping contact part between the conductive coating formed by printing and the nano far infrared coating, causing poor conduction or contact.
In order to solve the problem about the printed conductive coating supplying power to the infrared coating in existing technologies, the embodiment of the present disclosure provides an aerosol generating device with stable connection.

a tubular base 231, of which an inner space forms a chamber 232 configured to receive and heat a smokable material A; the tubular base 231 as a rigid carrier and an article to receive and accommodate the smokable material A may be made of high-temperature resistant and infrared transmissive materials such as quartz glass, ceramic or mica, etc. during implementations, preferably made of transparent materials, for example, a high-temperature resistant material with infrared transmissivity over 95% is employed;
an infrared emitting coating 233 formed on an outer surface of the tubular base 231; the infrared emitting coating 233 is capable of generating heat when electrified, thereby radiating infrared rays that can be used to heat the smokable material A, for example, the above far infrared rays of 3 μm to 15 μm. When the wavelength of the infrared rays matches with the wavelength absorbable by the volatile ingredient of the smokable material, the energy of the infrared rays is easy to be absorbed by the smokable material. Generally, during implementations, the infrared emitting coating 233 may be a coating made of ceramic materials such as zirconium, or Fe—Mn—Cu series, tungsten series, or transition metals and their oxide materials.
In a preferred embodiment, the infrared emitting coating 233 preferably is composed of an oxide of at least one metallic element among Mg, Al, Ti, Zr, Mn, Fe, Co, Ni, Cu, Cr, Zn, etc.; these metallic oxides when heated to an appropriate temperature can radiate far infrared rays having a heating effect; the thickness of the coating preferably may be controlled between 30 μm to 50 μm; the formation mode on the surface of the tubular base 231 may be achieved by spraying the oxides of the above metallic elements on the outer surface of the tubular base 231 through an atmospheric plasma spraying method and then curing it.

Specifically, the retaining mechanism includes a first retaining element 210 and a second retaining element 220 that are arranged in turn in a circumferential direction surrounding the infrared emitter 230; according to the preferred embodiment shown in
Meanwhile, to facilitate the cooperation and assembly between the first retaining element 210 and the second retaining element 220, the first retaining element 210 is provided with a first clamping protrusion 212 that is located at two ends of the length direction and a second clamping protrusion 213 that is located on the middle part; correspondingly, the second retaining element 220 defines a first clamping groove 222 adapted to the first clamping protrusion 212 and a second clamping groove 223 adapted to the second clamping protrusion 213; during the assembly process, the first clamping protrusion 212 is embedded into the first clamping protrusion 212, and the second clamping protrusion 213 is embedded into the second clamping groove 223, so that the first retaining element 210 is connected and fixed with the second retaining element 220.
Further, two ends of the first retaining element 210 in the length direction are provided respectively with a first support part 211 and a second support part 214 that are extending inwards in a radial direction; similarly, two ends of the second retaining element 210 are further provided with a third support part 221 and a fourth support part (not shown in figures due to the angle of view) that are extending inwards in a radial direction; the above support parts are arranged for the purpose of providing support for two ends of the infrared emitter 230 accommodated within the first retaining element 210 and the second retaining element 220, thereby preventing the infrared emitter 230 moving in the axial direction and thus retaining and securing the infrared emitter 230.
Further, referring to
In a preferred embodiment, extension lengths of the first conductive element 240 and the second conductive element 250 in the axial direction of the infrared emitter 230 are greater than the extension length of the infrared emitting coating 233, so that the circumferential current of the infrared emitting coating 233 is continuous and complete. In a preferred embodiment, to enable the first conductive element 240 to be stably retained on the inner wall of the first retaining element 210, the inner wall of the first retaining element 210 defines a groove 215 configured to fix the first conductive element 240. Specifically, the first conductive element 240 further includes an extension part 241 extended out from the main body along two sides thereof, such that the first conductive element 240 after being accommodated or retained within the groove 215 is prevented from an axial movement.
Further, in a more preferred embodiment, flexible materials capable of providing an elastic force, such as silicone rubber, polyimide, sponge, etc., may be formed within the groove 215 by means of gluing, filling or spraying, etc., so that the first conductive element 240, when accommodated within the groove 215, can stably contact or be attached to the surface of the infrared emitting coating 233 under the action of the flexible force.
Similar to the above first conductive element 240, the second conductive element 250 has the same shape, structure, fixing and installation method, and the technical personnel can understand and perform implementation with reference to the first conductive element 240.
On the basis of the above first conductive element 240 and second conductive element 250 being used as electrodes to supply power to the infrared emitting coating 233, the first conductive element 240 and the second conductive element 250 may be made of materials with good conductivity and low resistivity, such as gold, silver, copper, etc.

Similarly, the second conductive element 20, which is provided corresponding to the first conductive element 240a, is attached to the outer surface of the infrared emitter 230 in the circumferential direction on the other end; the first and second conductive elements serve as positive and negative electrodes respectively to supply power to the infrared emitter 230, forming a current in the axial direction rather than the radial direction indicated by the arrow r shown in
Further, the first conductive element 240a further includes an extension part 241a extended out from the main body, which on one hand prevents the first conductive element 240a moving in the circumferential direction within the groove 215a and which after being installed can extend to outside of the first retaining element 210a to be subsequently connected to positive and negative electrodes of the battery cell 14.
