Referring to fig. 1-4, the present invention provides a heating element for an aerosol generator, which comprises a filling cylinder 1 for placing a smokable material, an induction coil assembly 4 surrounding the filling cylinder 1, and a heating element 2. The heating element 2 comprises a heat insulation rod 21 and an induction heating pipe 22, a first end 201 of the heat insulation rod 21 protrudes into the stuffing cylinder 1, at least part of the periphery of the heat insulation rod is sleeved with the induction heating pipe 22, and a second end 202 of the heat insulation rod extends out of the stuffing cylinder 1 from the bottom wall of the stuffing cylinder 1 to be fixedly connected. Through cup jointing induction heating pipe 22 in first end 201 of heat insulating rod 21 in order to heat smokeable material, simultaneously the second end 202 of heat insulating rod 21 stretches out packing section of thick bamboo 1 from packing section of thick bamboo 1 diapire for fixed, like this on the basis of not influencing the smokeable material of heat conduction to packing section of thick bamboo 1, has reduced heat and has conducted to the shell from packing section of thick bamboo 1 bottom to effectively prevent equipment shell overheated and reduced heat loss.
In some embodiments, as shown in fig. 4, the induction coil assembly 4 includes a coil support 41 and an induction coil 42. The coil support 41 is convexly arranged on the periphery of the packing cylinder 1, and may include two annular convex rings arranged at intervals, and the two annular convex rings and the periphery of the packing cylinder 1 jointly form an annular placing groove 5 for placing the induction coil 42. The induction coil 42 is wound on the periphery of the stuffing cylinder 1 and is accommodated in the annular placing 5 groove. In practical applications, a spiral guide slot may be further provided in the annular placing groove 5, and the induction coil 42 is guided and positioned by the spiral guide slot. Correspondingly, the reaction heating tube is made of a magnetic conductive material, and is heated under the action of a magnetic field generated by the induction coil 42. For example, the induction heating pipe 22 may be made of a ferromagnetic material or a ferrimagnetic material. The induction heating tube 22 may be made of magnetic conductive metal or magnetic conductive alloy. Preferably, the induction heating tube 22 is made of metal or alloy with high magnetic permeability, so that the heating efficiency and the heating rate of the induction heating tube 22 can be improved.
In some embodiments, the coil support 41 may also be a cylindrical structure adapted to the stuffing cylinder 1, and is sleeved on the periphery of the stuffing cylinder 1 to support the stuffing cylinder 1. The coil holder 41 is provided at an outer circumference thereof with the annular placement groove in a circumferential direction, and the induction coil 42 is received in the annular placement groove and wound around the coil holder 41. Preferably, a gap exists between the packing cylinder 1 and the coil support 41, and the gap forms an air medium layer between the packing cylinder 1 and the coil support 41, so that the heat conduction in the packing cylinder 1 to the coil support 41 along the radial direction can be effectively reduced.
In some embodiments, as shown in FIGS. 1-4, the insulating bar 21 includes an insulating bar body 211 and a fixed seat 212. One end of the heat insulation rod body 211 protrudes into the stuffing cylinder 1 to form the first end 201. The part of the insulating rod body 211 accommodated in the stuffing cylinder 1, that is, at least part of the periphery of the first end 201, is provided with an annular groove 213. The induction heating tube 22 is accommodated in the annular groove 213, so as to be at least partially sleeved on the periphery of the first end 201. Through annular groove 213 fixes a position and spacing induction heating pipe 22, prevents that induction heating pipe 22 from taking place axial displacement, influencing the efficiency of generating heat. Preferably, the recess depth of the annular groove 213 relative to the outer surface of the first end 201 is equal to the wall thickness of the induction heating pipe 22, so that the outer surface of the induction heating pipe 22 and the outer surface of the heat insulation rod body 211 are smoothly transited, thereby forming a smooth surface on the outer periphery of the heating element 2, and facilitating the installation and heating of the smokable material. Further, the heat insulation rod body 211 may have a rod-like, needle-like, or spiral columnar structure. Preferably, the end of the first end 201 of the insulating rod 21 is tapered to facilitate insertion into the smokable material.
In some embodiments, as shown in fig. 4, the fixing seat 212 is sleeved on one end of the insulating rod body 211 extending out of the stuffing cylinder 1 from the bottom wall of the stuffing cylinder 1 to form the second end 202. The second end 202 is fixedly connected with the housing and/or the bracket 41 of the induction coil 42 to fix the heating element 2, so that the induction heating pipe 22 is not in direct contact with the stuffing cylinder 1 and the fixing structure arranged on the housing, and therefore, the heat of the induction heating pipe 22 is not directly transferred to the housing through contact conduction. Further, the fixing seat 212 and/or the heat insulation rod body 211 are made of a material with a low thermal conductivity coefficient. For example, zirconia ceramic can be used, and by utilizing the low thermal conductivity of zirconia ceramic, the heat generated by the induction heating tube 22 is difficult to be transferred to the casing through the second end 202 of the heat insulation rod 21, which not only improves the thermal efficiency, but also reduces the probability of overheating the casing. Of course, the fixed base 212 and/or the insulating rod body 211 may be made of quartz glass, ordinary glass, silicon carbide, or the like. In practice, the device housing is provided with a sleeve 100 for a fixed connection to said second end 202. The jacket 100 is tightly sleeved on one end, far away from the opening, of the filler cylinder 1, and one side of the jacket 100 is abutted to the fixed seat 212, so that the fixed seat 212 is clamped between the bottom wall of the filler cylinder 1 and the jacket 100, and the heating element 2 is fixed. Of course, the assembly manner of the second end 202 and the housing is not limited to the above examples, and other connection structures may be adopted, which is not limited herein.
In some embodiments, as shown in fig. 1, 3 and 4, the heating element further includes a temperature measuring element 3 for detecting the temperature of the induction heating tube 22, and the temperature measuring element 3 is embedded in the heat insulation rod 21 and electrically connected to the induction heating tube 22. Correspondingly, the heat insulation rod 21 is internally provided with an installation through hole 214 matched with the temperature measuring element 3. One end of the mounting through hole 214 extends to communicate with the induction heating tube 22, and the other end thereof penetrates through the second end 202. Preferably, the installation through hole 214 is L-shaped, and includes a first section 2141 extending along the axial direction of the insulation bar 21 and a second section 2142 bent with respect to the first section 2141 and extending to the induction heating tube 22. That is, the inner wall of the induction heating pipe 22 is exposed from the second section 2142. The temperature measuring element 3 extends from the first section 2141 of the mounting through hole 214, passes through the second section 2142, and is welded to the induction heating tube 22. The temperature of the induction heating tube 22 is monitored by the temperature measuring element 3, and the heating temperature is adjusted. In practical application, the temperature measuring element 3 can adopt a thermocouple, a temperature measuring sensor or a temperature measuring resistor.
