At present, the heating body which is most widely applied in the field of heating atomization is a columnar heating body, and the columnar heating body is mainly divided into two types: one is a columnar heating body formed by spirally winding a heating wire, and the other is a tubular heating body formed by winding a grid-shaped heating sheet into a C shape. The two electrodes of the two heating bodies are respectively arranged at the two opposite ends of the heating body, so that the following problems are brought: 1. the electrodes are required to be led out to the same end at two ends through electrode pins, and the leads occupy space during design, so that the positions of the leads need to be avoided during wrapping and matching of a liquid guide material outside the heating body, and the assembly difficulty is high; 2. the C-shaped tubular heating body is not in a full circle shape in the circumferential direction, and the radial supporting force is insufficient, so that the C-shaped tubular heating body is easy to deform to cause poor contact with a liquid guide material.

In addition, the heating value of the existing columnar heating body is not easy to adjust, and the size change is easy to occur during production and assembly, so that the consistency of products is influenced.

As shown in fig. 1 and 2, the tubular heat generating component according to the first embodiment of the present invention includes a ring-shaped connecting portion 10, at least two heat generating portions 20, at least two electrode portions 30, and an electrode pin 40 connected to the electrode portions 30.

The connection part 10 and the electrode part 30 are respectively located at opposite ends thereof in the axial direction of the entire heat generating component, and the heat generating part 20 is located at a middle position and connected between the connection part 10 and the electrode part 30.

The connecting portion 10 has two opposite annular end surfaces, the heat generating portions 20 are connected to one end surface of the connecting portion 10 and arranged around the end surface, and at least two heat generating portions 20 are spaced (not connected). The electrode portions 30 are connected to one end of the heating portion 20 away from the connecting portion 10, the electrode portions 30 are spaced apart and distributed corresponding to the positive and negative electrodes, and each electrode portion 30 is connected to an electrode pin 40 for connecting the positive and negative electrodes of a power supply such as a battery.

Each heating portion 20 has two opposite sides, each side being opposite to a corresponding side of another adjacent heating portion 20 with a gap 50. 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.

In the whole heating assembly, the connecting part 10 is arranged to connect at least two relatively independent heating parts 20 into a whole, so that the strength of the tubular structure of the heating assembly is improved. At least two electrode portions 30 are located at the same end of the heating element to facilitate assembly and connection to a battery in the atomizing device.

The heating part 20 is provided with a hollow structure, so that the heating part 20 is provided with a heating structure such as a heating line 21, the heating line is long, the area is small, the resistance is larger than that of the connecting part 10 and the electrode part 30, and more heat is generated after the power is on. Further, the amount of heat generation can be adjusted by adjusting the width, pitch, and the like of the heat generation line 21.

Further, the hollowed-out structure may include a plurality of through slots 201 and/or a plurality of notches 202 arranged at intervals along the length direction of the heat generating portion 20; the hollow structure is provided so that the heat generating portion 20 forms at least one heat generating line 21.

Specifically, the tubular heat generating component of the present embodiment 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. 2, and may be in other forms such as a meander shape or a wave 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 heating component, the wall thickness of the heating part is 0.03mm-0.5 mm. Alternatively, the tubular portion of the tubular heat generating component (including the connecting portion 10, the heat generating portion 20, and the electrode portion 30) is of an integral structure, and the overall wall thickness is 0.03mm to 0.5 mm.

The tubular heating component can be made of stainless steel alloy, nickel-chromium alloy, iron-chromium-aluminum alloy, titanium alloy, nickel-base alloy, hastelloy and other metal materials by cutting (specifically, wire cutting, laser cutting, electric spark and the like) and other processing modes.

Alternatively, the tubular portion of the tubular heat generating element (including the connecting portion 10, the heat generating portion 20, and the electrode portion 30) may employ a tube body as a base body, on which the connecting portion 10, the heat generating portion 20, and the electrode portion 30 are formed by cutting or the like, and a hollow structure is processed on the heat generating portion 20 to form the heat generating line 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 element 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 on 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.

In the tubular heat generating element of the present invention, the diameter of the entire heat generating element may be adjusted by increasing or decreasing the number of the heat generating portions 20, increasing or decreasing the width of the heat generating portions 20, or the like, as required by the required diameter.

As shown in fig. 3, in the tubular heat generating component according to the second embodiment of the present invention, the hollow 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. 4, a tubular heat generating component according to a third embodiment of the present invention, different from the first embodiment described above, is: 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 elements of the first and second embodiments.

It is understood that, for the tubular heat generating component 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.

In the tubular heat generating component of the first to third embodiments described above with reference to fig. 2 to 4, the through grooves 201 and the notches 202 are arranged to have a uniform width, that is, the through grooves 201 are equal in width to each other, the notches 202 are equal in width to each other, and the through grooves 201 and the notches 202 are also equal in width to each other on the heat generating member 20.

As shown in fig. 5, in a tubular heat generating component of a fourth embodiment of the present invention, 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.

As shown in fig. 6, the tube-shaped heat generating component according to the fifth embodiment of the present invention includes a ring-shaped connecting portion 10, at least two heat generating portions 20, at least two electrode portions 30, and an electrode pin 40 connected to the electrode portions 30.

The connecting portion 10 has two opposite annular end surfaces, and the heat generating portions 20 are connected to one end surface of the connecting portion 10 and arranged circumferentially along the end surface, with a space (non-connection) between at least two heat generating portions 20. The electrode portions 30 are connected to one end of the heating portion 20 away from the connecting portion 10, the electrode portions 30 are spaced apart and distributed corresponding to the positive and negative electrodes, and each electrode portion 30 is connected to an electrode pin 40 for connecting the positive and negative electrodes of a power supply such as a battery. 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.

By providing the hollow structure, one or more heating circuits 21 may be formed on each heating portion 21, and reference may be made to the first to third embodiments.

The hollow 301 may have a through hole structure having a polygonal shape, a circular shape, an elliptical shape, or the like.

Since the temperature of the installation position of the electrode part 30 is high in consideration of the heat of the heating part 20 being conducted to the electrode part 30, the heat conduction area is reduced by providing the hollow part 301 in the electrode part 30, so that a good heat insulation effect can be achieved, and the temperature difference between the temperature of the electrode part 30 and the temperature of the heating part 20 is small.

As shown in fig. 8, a tubular heat generating component according to a seventh embodiment of the present invention includes a ring-shaped connecting portion 10, at least two heat generating portions 20 connected to and circumferentially disposed along one end surface of the connecting portion 10, and an electrode portion 30 connected to one end of the heat generating portion 20 away from the connecting portion 10.
