In the first embodiment of the tubular heat generating component 100, as shown in fig. 5 and 6, the tubular heat generating component 100 includes two symmetrically arranged heat generating portions 20; one end of each heating part 20 far away from the connecting part 10 is connected with an electrode part 30. The hollowed-out structure of each heat generating portion 20 includes a plurality of through slots 201 and a plurality of notches 202. Wherein, the plurality of through slots 201 are arranged at intervals along the length direction of the heating part 20; two notches 202 are arranged between every two adjacent through grooves 201, and the two notches 202 are opposite to each other at intervals. The through groove 201 and the notches 202 are arranged such that the heat generating part 20 includes a plurality of heat generating rings connected in sequence in the length direction thereof, and the space 203 between two opposite notches 202 forms a connecting structure for connecting the heat generating rings.

The heating part 20 is divided by the center line thereof and can be divided into two heating lines 21 with the center line as the symmetry axis, that is, the two heating lines 21 are connected and symmetrical; the two heating lines 21 are connected in parallel. Each heating line 21 may be in a meander shape as shown in fig. 6, and may be in another form such as a meander shape or a glass shape.

In consideration of the strength of the entire heat generating component, the width L1 of the spacer 203 (between the two notches 202 facing each other) located at the center line of the heat generating portion 20 is preferably not less than 2 times the width L2 of the notch 202.

In the tubular heat generating component 100, the wall thickness of the heat generating portion is 0.03mm to 0.5 mm. Alternatively, the tubular portion (including the connecting portion 10, the heat generating portion 20, and the electrode portion 30) of the tubular heat generating component 100 has an integral structure, and the overall wall thickness is 0.03mm to 0.5 mm.

The tubular heating element 100 may be made of a metal material such as stainless steel alloy, nichrome, ferrochromium alloy, titanium alloy, nickel-based alloy, hastelloy, or the like, by a machining method such as cutting (specifically, wire cutting, laser cutting, electric discharge, or the like).

Alternatively, the tubular portion (including the connecting portion 10, the heat generating portion 20 and the electrode portion 30) of the tubular heat generating component 100 may adopt a tubular body as a base body, the connecting portion 10, the heat generating portion 20 and the electrode portion 30 are formed thereon by cutting or the like, and the hollow structure is processed on the heat generating portion 20 to form the heat generating circuit 21. Alternatively, the tubular portion (including the connecting portion 10, the heat generating portion 20, and the electrode portion 30) of the tubular heat generating module 100 may be formed by forming the flat plate-shaped connecting portion 10, the flat plate-shaped heat generating portion 20, and the flat plate-shaped electrode portion 30 on a metal sheet as a base by a cutting or other processing method, processing a hollow structure in the heat generating portion 20 to form the heat generating line 21, and finally bending the processed metal sheet into a tubular shape and welding both ends of the connecting portion 10 together.

Further, the diameter of the entire heat generating component may be adjusted by increasing or decreasing the number of the heat generating portions 20 of the tubular heat generating component 100, increasing or decreasing the width of the heat generating portions 20, or the like, as necessary according to the required diameter.

In the second embodiment of the tubular heat generating component 100, as shown in fig. 7, the hollowed-out structure on the heat generating portion 20 includes a plurality of notches 202 arranged at intervals and staggered along the length direction of the heat generating portion 20. The plurality of notches 202 are provided so that the heat generating portion 20 forms one heat generating line 21.

One heat generating line 21 is formed on the heat generating part 20, and it is advantageous to reduce the width of the heat generating part 20 and to form a heat generating element having a small diameter, compared to the case where two or more heat generating lines 21 are formed.

As shown in fig. 8, in the third embodiment of the tubular heat generating component 100, different from the first embodiment described above are: the hollow structure of each heating portion 20 forms two symmetrical heating areas on the heating portion 20, and each heating area includes two symmetrical heating circuits 21. Therefore, each heat generating member 20 has four heat generating lines 21, and the four heat generating lines 21 are sequentially connected in the width direction of the heat generating member 20. The heat generating member 20 of this embodiment is suitable for a tubular heat generating element having a larger diameter requirement than the tubular heat generating element 100 of the first and second embodiments.

It is understood that, for the tubular heat generating component 100 having the same diameter requirement, the heat generating portion 20 may also form one or more heat generating lines 21 according to the requirement of heat generation amount, atomization effect, and the like.

With reference to fig. 5 to 8, in the tubular heat generating component 100 of the first to third embodiments, the through grooves 201 and the notches 202 have the same width, that is, the through grooves 201 have the same width, the notches 202 have the same width, and the through grooves 201 and the notches 202 have the same width on the heat generating part 20.

In the fourth embodiment of the tubular heat generating component 100, as shown in fig. 9, unlike the first to third embodiments described above: in the longitudinal direction of the heat generating member 20, the width of the through groove 201 and/or the notch 202 located in the middle of the heat generating line 21 is larger than the width of the through groove 201 and/or the notch 202 located at both ends of the heat generating line 21.

Because the temperature of the middle portion of the heat generating portion 20 is higher than the temperatures of the two ends of the heat generating portion 20 due to the principle of heat radiation, the width of the through groove 201 and/or the notch 202 in the middle portion of the heat generating line 21 is larger than the width of the through groove 201 and/or the notch 202 at the two ends of the heat generating line 21, so that the distance between the middle portion and the two ends of the heat generating line 21 is large, and the overall heat generation amount of the heat generating portion 20 is uniform.

At least two heating parts 20 are connected in series through the connecting part 10, so that the power supply is externally connected in series, and the resistance value of the heating part can be larger than that of other heating parts with the same volume.
