[0043] For example, the heat generating body part 31, the first support part 32 and the second support part 33 are conductive bodies made of nickel-chromium-aluminum alloy or iron-chromium-aluminum alloy. The nickel-chromium-aluminum alloy and the iron-chromium-aluminum alloy are only examples and do not limit the present application.
[0044] It should be noted that isolation means isolation between different parts due to physical separation or spatial separation.
[0045] In the heat generating structure of the present embodiment, the first support part 32 and the second support part 33 are provided at both ends of the heat generating body part 31 of the heat generating member 3, so that both ends of the heat generating member 3 have higher structural strength and are prevented from deforming, thereby improving the stability and reliability of the heat generating structure.
[0046] Meanwhile, by electrically isolating the first support part 32 from the first electrical connector 1 and / or the second electrical connector 2 and electrically isolating the second support part 33 from the first electrical connector 1 and / or the second electrical connector 2, the first electrical connector 1 and the second electrical connector 2 can be prevented from being directly connected.
[0047] In some embodiments, as shown in FIG. 1, Figure 1 , Figure 2 and Figure 3As shown, the heat generating structure further comprises a first pin 4 and a second pin 5, the first pin 4 is connected with the first electrical connector 1, and the second pin 5 is connected with the second electrical connector 2. One of the first pin 4 and the second pin 5 is used to connect the positive pole of the external power supply, and the other is used to connect the negative pole of the external power supply. For example, the first electrical connector 1 and the second electrical connector 2 are in the shape of a sheet or a column, and the first pin 4 and the second pin 5 are also in the shape of a sheet or a column. The sheet and the column here are only examples and do not limit the present application.
[0048] In some embodiments, in order to improve the support of the first support part 32 and the second support part 33, as shown in Figure 1 、 Figure 2 and Figure 3 , the first support part 32 and the second support part 33 are respectively integrated structures extending in opposite directions on both sides of the heat generating main body part 31. Among them, the first support part 32 and the second support part 33 are solid structures or hollow structures. For example, as shown in Figure 1 、 Figure 2 and Figure 3 , the first support part 32 and the second support part 33 are respectively in the shape of a strip or a sheet, and the first support part 32 and the second support part 33 can also be in the shape of a straight line or a curve. The strip, the sheet, the straight line and the curve here are only examples and do not limit the present application.
[0049] In some embodiments, as shown in Figure 1 、 Figure 2 and Figure 3 , the first support part 32 and the second support part 33 are the same in size and / or shape, and when the first support part 32 and the second support part 33 are conductive bodies, the uniformity of heat can be ensured. In other embodiments, the first support part 32 and the second support part 33 are different in size and / or shape.
[0050] In some embodiments, the heat generating part 3 can be curled, that is, a flexible body, which can be in the shape of a plane as shown in Figure 1 and Figure 3 or at least partially in the shape of a curved arc surface as shown in Figure 2 . For example, the heat generating part 3 can be curled into a cylindrical shape or a circular arc shape. The cylindrical shape and the circular arc shape here are only examples and do not limit the present application.
[0051] In the related art, when the upper and lower ends of the heating net have a plurality of protruding ends, the protruding ends are easy to touch together after being curled, resulting in uneven heat, and even the temperature of some areas is too high and the wick is burnt. Secondly, when the liquid absorbing cotton used to absorb the liquid aerosol generating substrate expands after being curled, the structure strength of the upper and lower ends of the heating net is too weak, which is easy to collapse inward, resulting in changes in the airway, and even too much collapse, resulting in liquid leakage. The heating element 3 after being curled in the present application does not have a plurality of protruding ends at both ends and has higher structure strength, so as to solve the problems of uneven heat caused by the protruding ends touching together after being curled and the structure strength of both ends being too weak to collapse inward.
[0052] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , in order to avoid the existence of protruding ends, the end face of the first support part 32 and the second support part 33 away from the heating main body part 31 is a flat structure, for example, a plane. The plane here is only an example and does not limit the present application.
[0053] In some embodiments, as shown in Figure 1 , the heating main body part 31 includes at least two heating units 311, and the at least two heating units 311 are arranged side by side in opposite directions at both sides of the heating main body part 31. The contact of one end of the heating unit 311 is connected to the first support part 32, and the contact of the other end of the heating unit 311 is connected to the second support part 33. Moreover, the heating unit 311 includes at least one opening 3111, that is, the heating main body part 31 is a mesh structure. It can be understood that the at least one can be one, two, three or any number.
[0054] For example, the heating unit 311 can be a heating net with one opening 3111 as shown in Figure 1 , or a heating net with two openings 3111 as shown in Figure 3 , and the two openings 3111 are arranged side by side in opposite directions at both ends of the heating main body part 31.
[0055] In some embodiments, the shape of the opening 3111 is polygonal (such as honeycomb, rhombus, rectangle, triangle or pentagon, etc.), circular or elliptical, etc.
[0056] In some embodiments, the contact point at one end of the heating unit 311 has a first protrusion 3112 protruding toward the first support portion 32, so as to connect the first support portion 32 through the first protrusion 3112; and / or, the contact point at the other end of the heating unit 311 has a second protrusion 3113 protruding toward the second support portion 33, so as to connect the second support portion 33 through the second protrusion 3113. Furthermore, the first protrusion 3112 and the second protrusion 3113 are integrally formed with the heating unit 311.
[0057] In some embodiments, when the first support portion 32 and the second support portion 33 are insulators, at least two heating units 311 form a heating area. In other embodiments, when the first support portion 32 and the second support portion 33 are conductors, at least two heating units 311, the first support portion 32, and the second support portion 33 form a heating area.
[0058] like Figure 4 As shown, some embodiments of this application disclose an electronic atomizing device 300, including the heating structure described in any of the above embodiments, wherein the heating structure will not be described in detail here.
[0059] The electronic atomizing device 300 also includes an atomizing component 100 and a power supply component 200. The atomizing component 100 includes an atomizing core assembly, which includes an atomizing core, a liquid-absorbing element (such as absorbent cotton) surrounding the atomizing core, and a heating structure disposed on the atomizing core. In use, the atomizing core absorbs liquid aerosol in the storage space through the liquid-absorbing element to generate a matrix. The heating structure is connected to the power supply component 200 and is energized to generate heat, causing the liquid aerosol in the atomizing core to atomize. The user inhales through the suction port of the atomizing component 100. Under the action of suction, air enters the atomizing core from the air intake channel of the atomizing component 100, mixes with the atomized aerosol in the atomizing core, and is discharged from the suction port after passing through the air outlet channel of the atomizing component 100.
[0060] By implementing this application, the following beneficial effects can be achieved:
[0061] In the heating structure of this application, by providing a first support portion 32 and a second support portion 33 at both ends of the heating body portion 31 of the heating element 3, the two ends of the heating element 3 have higher structural strength, avoid deformation, and improve the stability and reliability of the heating structure.
[0062] Meanwhile, by electrically isolating the first support portion 32 from the first electrical connector 1 and / or the second electrical connector 2, and by electrically isolating the second support portion 33 from the first electrical connector 1 and / or the second electrical connector 2, direct connection between the first electrical connector 1 and the second electrical connector 2 can be prevented.
