Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more features.

[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0038] The embodiments of the present application provide a heating element, a heating module, and an electronic smoking device to solve the problem of poor heating effect of the electronic smoking device. The embodiments will be described below with reference to the accompanying drawings.

[0039] See also Figure 1 and Figure 2 The embodiment of the present application provides a heating fin tube 1, which has a plurality of heating parts 12 arranged in sequence; an isolation tube 22, the heating fin tube 1 is sleeved in the isolation tube 22, and the isolation tube 22 includes a plurality of isolation parts 221 arranged in sequence, each isolation part 221 is arranged corresponding to a heating part 12, and adjacent isolation parts 221 are arranged at intervals to reduce heat transfer between the isolation parts 221.

[0040] By providing multiple heating elements 12, each heating element 12 corresponding to a different area, the heating element tube 1 achieves simultaneous heating of the non-uniform smoking medium at multiple different temperatures, resolving the issue of poor heating performance in the electronic smoking device. Furthermore, by providing a corresponding isolation portion 221 for each heating element 12 and spacing adjacent isolation portions 221, the thermal resistance between the isolation portions 221 is increased, thereby reducing heat exchange between the isolation portions 221, facilitating temperature control in the electronic smoking device for the area corresponding to each heating element 121.

[0041] See also Figure 1 and Figure 2The heating fin tube 1 and the isolation tube 22 are both cylindrically arranged. The heating fin tube 1 is sleeved on the isolation tube 22. The isolation tube 22 is used to isolate the heating fin tube 1. The isolation tube 22 includes a plurality of isolation parts 221. In this embodiment, the number of isolation tubes 22 is set to two. The two isolation parts 221 are sequentially spaced along the core axis direction of the isolation tube 22. The isolation parts 221 are arranged in a one-to-one correspondence with the heating parts 12. In some embodiments of the present application, the isolation tube 22 also includes an insulation ring. The two adjacent isolation parts (221) are connected and fixed by an insulation ring (not shown in the figure). The setting of the insulation ring can increase the thermal resistance between the two adjacent isolation parts, thereby further reducing the heat exchange between the two adjacent isolation parts.

[0042] In this embodiment, the isolation tube 22 is made of any one of SPCC, SECC, SUS304, SUS316, AL, and Cu. The wall thickness of the isolation tube 22 is H, and 0.08 mm ≤ H ≤ 0.2 mm.

[0043] See also Figure 1 and Figure 3 The carrier film 21 is used to support the heating film tube 1. The carrier film 21 includes an insulating portion 211, a carrier portion 212, a sealing portion 213 and at least one bundling portion 214, which are arranged in sequence. The carrier portion 212 is attached to the outer wall of the heating film tube 1, the insulating portion 211 is attached to the inner wall of the heating film tube 1, and the sealing portion 213 is attached to the side of the carrier portion 212 away from the heating film tube 1. The bundling portion 214 is used to bundle the sealing portion 213 to reduce the occurrence of the carrier film 21 falling off the heating film tube 1. In this embodiment, the number of the bundling portion 214 is set to one. The bundling portion 214 is bundled with the sealing portion 213 and is located between two adjacent heating portions 12, thereby strengthening the structural strength between the two heating portions 12. In other embodiments of the present application, the number of the bundling portions 214 is set to multiple, and the multiple bundling portions 214 are arranged in sequence and spaced apart and respectively located between the two heating portions 12.

[0044] See also Figure 3 , the length of the insulating portion 211 is a, the circumference of the heating plate tube 1 is b, and the length of the sealing portion 213 is c, a>b+0.5mm, b=c. By making the length of the insulating portion 211 greater than the circumference of the heating plate tube 1, the insulating portion 211 can completely cover the inner wall of the heating plate tube 1, thereby avoiding the occurrence of a short circuit in the heating plate tube 1 due to direct contact between the heating plate tube 1 and the isolation tube 22. By making the length of the sealing portion 213 equal to the circumference of the heating plate tube 1, the sealing portion 213 can wrap around the heating plate tube 1 again on the basis of the supporting portion 212, which is beneficial to reduce the occurrence of the supporting portion 212 falling off the heating plate tube 1. In this embodiment, the supporting film 21 is made of polyimide film.

[0045] See also Figure 1and Figure 3 In this embodiment, the number of heating parts 12 is set to two. In other embodiments of the present application, the number of heating parts 12 is set to multiple, and the multiple heating parts 12 are arranged in sequence and spaced apart along the length direction of the heating part 12. The common pin 11 is connected to one side of the heating part 121 in the width direction, and the connecting pin 122 is arranged on the other side of the heating part 121 in the width direction. The connecting part includes one or more heating wires 1211, one end of the heating wire 1211 is fixedly connected to the connecting pin 122, and the other end is connected to the common pin 11. When the number of heating wires 1211 is set to multiple, the multiple heating wires 1211 are arranged in sequence and spaced apart along the length direction of the heating part 12.

[0046] In this embodiment, the heater tube 1 is made of any one of nickel-chromium alloy, nickel-iron alloy, stainless steel, iron-chromium-aluminum, titanium, and nickel. The temperature coefficient of resistance (TCR) of the heater tube 1 is ≥ 1000 at 20°C. The resistance of each heating portion 121 is greater than 0.4Ω and less than 1Ω. This allows a larger current to flow through the heating portion 121 while ensuring battery current safety, thereby increasing the maximum heating power of the heater tube 1.

[0047] See also Figure 4 and Figure 5 The embodiment of the present application further provides a heating module 3 , comprising the above-mentioned heating element 2 , a heat preservation tube 34 , an outer shell 31 , an end cover 32 and a base 33 .

[0048] See also Figure 4 and Figure 5 The heat preservation tube 34 is used to reduce the heat loss generated by the heating element 2. The heat preservation tube 34 is fixedly sleeved on the outer wall of the heating element 2. The outer shell 31 is sleeved on the outer surface of the heat preservation tube 34. The end cover 32 is fixedly connected to one end of the outer shell 31. The base 33 is fixedly connected to the end of the outer shell 31 away from the end cover 32. Specifically, the side of the end cover 32 close to the outer shell 31 is inserted into the outer shell 31 from one end of the outer shell 31. A buckle 322 is integrally formed on the outer wall of the end of the end cover 32 inserted into the outer shell 31. The outer shell 31 is provided with a clamping hole 311 that cooperates with the buckle 322. The base 33 is inserted into the outer shell 31 from the end of the outer shell 31 away from the end cover 32 and is fixedly connected to the inner wall of the outer shell 31.
