It should be noted that the Temperature Coefficient of Resistance (TCR) represents the relative change of resistance value when the temperature changes by 1 degree celsius, and has a negative temperature coefficient and a positive temperature coefficient, where the unit is ppm/degree celsius. Wherein, ptc (positive Temperature coefficient) refers to positive Temperature coefficient, and broadly refers to material or component with large positive Temperature coefficient; PTC is generally referred to as a positive temperature coefficient thermistor. Ntc (negative Temperature coefficient) refers to a negative Temperature coefficient, and generally refers to thermistors and materials having a negative Temperature coefficient.

In the embodiment using the thermocouple, the threaded section 210 and the straight section 220 are welded together using different kinds of metal materials, respectively. It is understood that in other embodiments, the temperature control members 200 may be arranged in straight line segments 220 or in threaded segments 210.

In this embodiment, the threaded section 210 of the temperature control member 200 is in a spiral rising shape, and the length of the threaded section 210 is equal to the length of the cavity 101, so that the heat energy transfer can be faster and more uniform. In other embodiments, the length of the threaded section 210 of the temperature control member 200 may be smaller or larger than the length of the second body portion 120, and the threaded section 210 may be replaced by a planar spiral coil.

In this embodiment, the threaded section 210 and the linear section 220 are both disposed in the middle of the cavity 101, which is beneficial to uniform distribution of generated heat energy. In other embodiments, the threaded segment 210 and the linear segment 220 may be disposed close to the inner wall of the cavity 101 to further increase the heat transfer rate.

In this way, the components can be smoothly arranged in the cavity 101 of the housing 100.

Specifically, the first body portion 110 is tapered, and the second body portion 120 is hollow and cylindrical. Thus, when the first tapered body 110 is inserted into the aerosol product, the generated resistance is small, and the user can easily insert the housing 100 into the gap of the aerosol product without a large force, so that the deformation of the aerosol product can be effectively avoided, and the service life of the heating component can be protected and prolonged.

Through the arrangement, the requirements that the first main body part 110 is high in hardness and the second main body part 120 is high in heat conduction rate can be met. The second main body 120 is made of ceramic, and the ceramic material does not absorb or reflect the alternating magnetic field, so that the heating efficiency of the heating element is not affected.

Thus, the temperature control member 200 is prevented from short-circuiting with the second main body portion 120, and plays an insulating role; meanwhile, the ceramic surface is effectively prevented from being damaged by infrared radiation prevention and acid and alkali resistance, and the protective effect is achieved.

Optionally, the functional glaze layer is one or more of lime glaze, feldspar glaze, lead-free glaze, boron glaze and lead-boron glaze. Or, the functional glaze layer may be replaced by an insulating paint or material, for example, a metal oxide particle coating, and the material composition of the functional glaze layer specifically includes metal oxide particles, polyvinylidene fluoride and N-methylpyrrolidone, wherein the material of the metal oxide particles may be selected from aluminum oxide, titanium dioxide, zinc oxide, magnesium oxide, and combinations thereof.
