For example, in the preparation, the temperature measurement is performed by forming an insulating layer on the surface of the outer emitting element 31 and then spraying the first thermocouple material coating 32 and the second thermocouple material coating 33.
Specifically, the first thermocouple material coating 32 and the second thermocouple material coating 33 are both annular coatings around the infrared heating element 31; and, a first thermocouple material coating 32 is adjacent to a first end 310 of the heater 30 in the axial direction, and a second thermocouple material coating 33 is adjacent to a second end 320 of the heater 30 in the axial direction. And, the first thermocouple material coating 32 and the second thermocouple material coating 33 are in contact, or at least partially overlapping, thereby forming an electrical connection therebetween.
Further in some implementations, the first thermocouple material coating 32 and the second thermocouple material coating 33 are each connected to the circuit board 140 by leads, thereby enabling the circuit board 140 to obtain the temperature of the heater 30 by sampling the thermoelectric voltage difference therebetween. For example, in one implementation, the leads are soldered on the first thermocouple material coating 32 near the first end 310 and, after soldering the leads on the second thermocouple material coating 33 near the second end 320, are separately connected to the circuit board 140.
Or in the preferred embodiment shown in fig. 5 to 7, the heater 30 further includes:
a first electrode coating 341 formed on the infrared heating element 31 near the first end 310; the first electrode coating 341 partially overlaps or contacts the first thermocouple material coating 32 to form a communication and is insulated from the infrared heating element 31;
a second electrode coating 342 formed on the infrared heating element 31 proximate the second end 320; the second electrode coating 342 partially overlaps or contacts the second thermocouple material coating 33 to form a communication and is insulated from the infrared heating element 31;
further, after the circuit board 140 is connected to the first electrode coating 341 and the second electrode coating 342 through electrical terminals, electrical contacts, leads, etc., respectively, the temperature of the heater 30 can be obtained by measuring the thermoelectric potential between the first thermocouple material coating 32 and the second thermocouple material coating 33.
The first electrode coating 341 and the second electrode coating 342 are each annular in shape. The first electrode coating 341 and the second electrode coating 342 may be electrode coatings formed by dipping or coating, etc., and may generally be metals or alloys including low resistivity silver, gold, palladium, platinum, copper, nickel, molybdenum, tungsten, niobium, or their alloys.
Or in still other implementations, the connection to the circuit board 140 may also be facilitated by at least one of an electrode ring, patch electrode, spot electrode, plate electrode, track electrode, coated electrode, etc. that is provided on the first thermocouple material coating 32 and the second thermocouple material coating 33, respectively, by riveting or welding, etc.
In the preferred implementation shown in the figures, the first thermocouple material coating 32 and the second thermocouple material coating 33 have substantially the same extension length. And, the extension length of the first thermocouple material coating layer 32 and the second thermocouple material coating layer 33 is smaller than the extension length of the infrared emission coating layer 312.
Further in still other variations, infrared heating element 31 is made to be a non-electrically-induced infrared emitting element by a material change; instead, the infrared heating element 31 is a thermally induced infrared heating element 31. For example, coatings made of thermally-induced infrared emitting materials, such as ceramic-based materials, e.g., zirconia, or Fe-Mn-Cu-based metals, tungsten, or transition metals and their oxide materials, which are capable of being thermally activated to emit infrared radiation.
Accordingly, the resistances of the first thermocouple material coating layer 32 and the second thermocouple material coating layer 33 are controlled to be about 10 to 30 μm in thickness by thickness, and the first thermocouple material coating layer 32 and the second thermocouple material coating layer 33 connected in series have a total resistance connected in series of about 0.5 Ω to 3 Ω by proper material selection. The first thermocouple material coating 32 and the second thermocouple material coating 33 can be used as functions of a resistance heating element and the first electrode coating 341 and the second electrode coating 342 are supplied with electricity to generate joule heat, which excites the thermally-induced infrared heating element 31 to radiate infrared rays.
In the above implementation, the first thermocouple material coating 32 and the second thermocouple material coating 33 are formed on the outside of the infrared heating element 31. Or in yet other variations, the first thermocouple material coating 32 and the second thermocouple material coating 33 are formed on the inner surface of the infrared heating element 31 by transfer printing, deposition, or the like.
And, in a preferred implementation, the first thermocouple material coating 32 and the second thermocouple material coating 33 are located outside of the infrared emission coating 312; i.e. the first thermocouple material coating 32 and the second thermocouple material coating 33 are not located inside the infrared emitting coating 312, in order to avoid blocking the infrared radiation emitted by the infrared emitting coating 312 towards the aerosol-generating article.
