Referring to fig. 1 to 15, an embodiment of the present utility model provides a heating assembly including a first electric heating layer 21, a second electric heating layer 22, and an insulating substrate 1 having a plate shape, wherein:

the insulating base 1 has a first surface 11 and a second surface 12 disposed opposite to each other in its own thickness direction;

the first electrothermal layer 21 covers the first surface 11 of the insulating substrate 1, and the thickness of the first electrothermal layer 21 is 4 micrometers to 18 micrometers;

the second electrothermal layer 22 covers the second surface 12 of the insulating substrate 1, and the thickness of the second electrothermal layer 22 is 4 micrometers to 18 micrometers.

In the present embodiment, in the specific implementation, the material of the insulating base 1 may be an insulating ceramic, for example, an insulating ceramic material of the type of alumina ceramic, aluminum nitride ceramic, silicon carbide ceramic, silicon nitride ceramic, or the like; alternatively, the material of the insulating base 1 may be a surface insulating metal, and for example, the material of the insulating base 1 may be a valve metal, that is, a metal material having an insulating oxide film formed on the surface, such as titanium having an insulating oxide film formed on the surface, aluminum having an insulating oxide film formed on the surface, or the like; alternatively, the material of the insulating base 1 may be glass, and of course, the material of the insulating base 1 may be other insulating materials as long as the use requirement can be satisfied, which is not particularly limited in this embodiment.

In this embodiment, in the specific implementation, the material of the first electrothermal layer 21 may be any one of silver, aluminum, copper, nickel, platinum, titanium, chromium, silver alloy, aluminum alloy, copper alloy, nickel alloy, platinum alloy, titanium alloy, and chromium alloy, and of course, other types of electrothermal materials may be used, so long as the first electrothermal layer 21 can be energized to generate heat, which is not limited in particular in this embodiment. Similarly, the material of the second electrothermal layer 22 may be any one of silver, aluminum, copper, nickel, platinum, titanium, chromium, silver alloy, aluminum alloy, copper alloy, nickel alloy, platinum alloy, titanium alloy, and chromium alloy, as long as the second electrothermal layer 22 is able to generate heat by being energized, which is not particularly limited in this embodiment. In addition, in the embodiment, the first electrothermal layer 21 and the second electrothermal layer 22 may be coated on the corresponding surfaces of the insulating substrate 1 by embedding, bonding, electroplating, etc., so long as the use requirement can be satisfied, and the specific manner in which the first electrothermal layer 21 is coated on the first surface 11 of the insulating substrate 1 and the specific manner in which the second electrothermal layer 22 is coated on the second surface 12 of the insulating substrate 1 are not particularly limited in this embodiment.

In this embodiment, in the implementation, the electrical connection relationship between the first electrothermal layer 21 and the second electrothermal layer 22 may be series connection or parallel connection, which may be determined according to the actual needs, and this embodiment is not limited specifically.

In the technical scheme of the embodiment, the electric heating layers with the thickness of 4-18 micrometers are covered on the front and back sides (namely the first surface 11 and the second surface 12) of the plate-shaped insulating matrix 1, and the two electric heating layers (namely the first electric heating layer 21 and the second electric heating layer 22) can directly generate heat after being electrified.

Moreover, since the first surface 11 and the second surface 12 are two outer surfaces having the largest surface area on the outer surface of the plate-shaped insulating base 1, by covering the two electrothermal layers connected in series on the first surface 11 and the second surface 12 of the plate-shaped insulating base 1, the area of heat generated by the heating assembly can be maximized, and thus the heating efficiency of the heating assembly can be maximized, which is advantageous in that the herb product can generate aerosol more rapidly.

Particularly, by reasonably setting the thickness of the first electric heating layer 21 and the second electric heating layer 22 to be 4 micrometers-18 micrometers, on one hand, the phenomenon that the electric heating layer is excessively high in resistance value due to the fact that the thickness of the electric heating layer is excessively thin (smaller than 4 micrometers) can be avoided, and further, the phenomenon that the electric heating layer is excessively high in temperature after being electrified and heated due to the fact that the electric heating layer is excessively high in resistance value can be avoided, and therefore the phenomenon that the insulating substrate 1 is broken due to the fact that the insulating substrate is subjected to excessively high temperature for a long time after being used can be avoided, and the service life of the heating assembly is prolonged; on the other hand, the electric heating layer can be prevented from being too thick (more than 18 micrometers) to cause too small resistance value of the electric heating layer, and further the electric heating layer can be prevented from being too small in resistance value to cause too small temperature generated after the electric heating layer is electrified and heated to be unable to reach the heating temperature (generally 200-400 ℃) required by herbal products; that is, the thickness of the first electrothermal layer 21 and the second electrothermal layer 22 of the heating assembly provided in this embodiment is reasonably set to 4-18 micrometers, so that the herbal product can be heated to a desired temperature quickly, aerosol can be generated quickly by the herbal product, and the service life of the heating assembly can be prolonged.

Further, referring to fig. 3 to 4, 7 to 10, and 15, in an exemplary embodiment of the present utility model, the insulating base 1 is formed with a pointed structure 13 at one end in a length direction thereof (a length direction of the insulating base 1, i.e., an up-down direction as shown in fig. 3, 7 to 10, 12, and 15), and illustratively, the insulating base 1 is formed with the pointed structure 13 at an upper end thereof. So arranged, in some use scenarios in which the heating assembly of the present embodiment is applied to a heating non-combustion device, the insulating base 1 covered with the electric heating layer can be smoothly inserted into a herbal product from one end having the pointed structure 13 for use. In the embodiment, the pointed structure 13 may be a tip, a triangle, or a wave, as long as the use requirement can be satisfied, which is not limited in this embodiment.

In this way, in some use scenarios of applying the heating assembly of the present embodiment to the heating non-combustion apparatus, after the first electric heating layer 21 and the second electric heating layer 22 are connected to the host power supply 9 of the heating non-combustion apparatus, current can fully flow through the whole first electric heating layer 21 and the whole second electric heating layer 22, so that both the first electric heating layer 21 and the second electric heating layer 22 can obtain better heating effects, that is, the heating areas of the first electric heating layer 21 and the second electric heating layer 22 are improved to the greatest extent.

Alternatively, in an exemplary embodiment of the present utility model, the series connection between the upper end of the first electric heating layer 21 and the upper end of the second electric heating layer 22 may be achieved by:

In this embodiment, in the implementation, the material of the conductive connection layer 3 may be the same as the material of the first electrothermal layer 21 and the second electrothermal layer 22, or may be different from the material of the first electrothermal layer 21 and the second electrothermal layer 22, so long as the requirement of use can be met, which is not particularly limited in this embodiment.

In addition, in the embodiment, the conductive connection layer 3 may be covered on the pointed structure 13 of the insulating substrate 1 by welding, bonding, electroplating, etc., so long as the use requirement can be met, and the specific manner of covering the pointed structure 13 with the first electrothermal layer 21 is not particularly limited in this embodiment.

Alternatively, in another exemplary embodiment of the present utility model, the series connection between the upper end of the first electric heating layer 21 and the upper end of the second electric heating layer 22 may also be achieved by:
