[0041] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0042] Please see Figure 1 and Figure 2 This application provides a heating assembly 100, which includes a heating element 1, a housing 2, and a temperature measuring component 3. Specifically, the heating element 1 can receive electrical power from a power source to generate heat, thereby heating an aerosol to form an article, which is then used to generate an aerosol for users to inhale. The housing 2 is fitted over the outer periphery of the heating element 1. The temperature measuring component 3 includes an elastic element 31 and a temperature measuring element 32. The elastic element 31 is connected to the housing 2 and fixes the temperature measuring element 32 to the housing 2. The elastic element 31 is used to receive the heat from the heating element 1 so that the temperature measuring element 32 can detect the temperature of the heating element 1. In this embodiment, by fixing the temperature measuring element 32 to the housing 2 with the elastic element 31, the position of the temperature measuring element 32 is kept stable, improving reliability and consistency, and facilitating effective control of the temperature of the heating element 1.

[0043] In some embodiments, please refer to Figure 3 The elastic element 31 is provided with a contact piece 311, which adheres to and abuts against the surface of the heating element 1 and is fixed to the temperature measuring element 32. By adhering the contact piece 311 to the heating element 1, the contact piece 311 and the heating element 1 are in surface contact, increasing the contact area between the contact piece 311 and the heating element 1, thereby making the temperature measurement result of the temperature measuring element 32 more accurate.

[0044] In some embodiments, please refer to Figure 3 and Figure 4The elastic element 31 includes a fixing part 312, which is connected to the contact piece part 311 and the outer shell 2. Specifically, the fixing part 312 is provided with a through hole 3121, and the outer shell 2 is provided with a fixing post 21. The fixing post 21 extends from the outer shell 2 towards the heating element 1, passes through the through hole 3121, and has an abutment ring edge at the end of the fixing post 21 away from the outer shell 2. The abutment ring edge abuts against the fixing part 312, so that the abutment ring edge and the outer shell 2 clamp the fixing part 312. As an example, during production assembly, the fixing post 21 is passed through the through hole 3121, and then the end of the fixing post 21 away from the outer shell 2 is heat-melted to form the abutment ring edge. As another example, the fixing post 21 is manufactured independently, and the abutment ring edge is manufactured simultaneously. During production assembly, the fixing post 21 is passed through the through hole 3121, and then the end of the fixing post 21 facing the outer shell 2 is fixed to the outer shell 2 by ultrasonic welding.

[0045] In some embodiments, there are multiple fixing portions 312, which are disposed on the outer periphery of the contact piece portion 311 and spaced apart. The fixing portions 312 are connected to the outer shell 2, making the connection between the elastic member 31 and the outer shell 2 more stable, thereby making the temperature measuring member 32 more stably fixed to the outer shell 2. In other embodiments, to match the multiple fixing portions 312, there are also multiple fixing posts 21, with one fixing post 21 clamping and fixing one fixing portion 312 to the outer shell 2.

[0046] In some embodiments, the elastic element 31 is made of a metallic material and has good electrical conductivity, electrical conductivity and deformation properties.

[0047] In some embodiments, there are multiple spaced elastic elements 31, and there are also multiple temperature measuring elements 32 that match the multiple elastic elements 31. The temperature of multiple heating areas 13 of the heating element 1 is detected by the multiple elastic elements 31 and the multiple temperature measuring elements 32.

[0048] In some embodiments, please refer to Figure 3 The temperature measuring element 32 is located on the side of the contact plate 311 facing the outer shell 2, which is beneficial for the contact plate 311 to better receive the heat from the heating element 1, thereby making the detection results of the temperature measuring element 32 more accurate.

[0049] In some embodiments, please refer to Figure 3The temperature sensing element 32 includes a first thermocouple wire 321 and a second thermocouple wire 322. The first thermocouple wire 321 and the second thermocouple wire 322 are made of different materials, thereby forming a temperature-sensing thermocouple between the first thermocouple wire 321 and the second thermocouple wire 322. As an example, the first thermocouple wire 321 serves as the positive electrode of the thermocouple, and the second thermocouple wire 322 serves as the negative electrode of the thermocouple. The positive electrode can be made of nickel-chromium alloy wire, and the negative electrode can be made of nickel-silicon alloy wire, forming a K-type thermocouple. The surfaces of the first thermocouple wire 321 and the second thermocouple wire 322 can be sprayed or plated with an insulating layer for insulation. As another example, the first thermocouple wire 321 and the second thermocouple wire 322 are made of two different materials selected from thermocouple materials such as nickel, nickel-chromium alloy, nickel-silicon alloy, nickel-chromium, copper alloy, constantan bronze, and iron-chromium alloy.

[0050] In some embodiments, please refer to Figure 4 The outer casing 2 is provided with a first opening 22, which corresponds to the elastic element 31. The first opening 22 reduces the contact area between the outer casing 2 and the elastic element 31, thereby reducing the amount of heat received and minimizing the impact on the detection results of the temperature measuring element 32.

[0051] In some embodiments, the outer casing 2 includes a first casing 23 and a second casing 24, the first casing 23 and the second casing 24 are connected, and the first opening 22 and the fixing post 21 are both disposed in the first casing 23.

[0057] In some embodiments, please refer to Figure 2 The second end cap 5 is provided with a protrusion 53, which is fixed to the side wall of the receiving groove 52.
