[0023] Figure 4 shows the structure of a metallic conductor. Detailed Implementation

[0024] As shown in Figures 1 to 4, this application provides a cigarette heating device, including: a first housing 1, a heating component 2, a thermocouple, a conductive component 3, and a battery component; the heating component 2 and the conductive component 3 are both disposed inside the first housing 1, and the conductive component 3 is connected to the heating component 2, the thermocouple, and the battery component.

[0025] Specifically, the conductive component 3 is disposed at the first end of the first housing 1, and a heating chamber is disposed at the second end of the first housing 1. The heated smoke product is placed in the heating chamber and then heated by the heating component 2.

[0026] The conductive component 3 includes a second housing 31, a fixing part 32, a metal conductor 33, and a connecting wire 34. A connecting hole 311 is provided at the center of the second housing 31, and a connecting groove 312 is provided on the outer edge of the second housing 31. The fixing part 32 is disposed in the connecting groove 312, and the metal conductor 33 is inserted into the connecting groove 312 and engaged with the fixing part 32. The first end of the connecting wire 34 is located between the fixing part 32 and the metal conductor 33, and the second end of the connecting wire 34 passes through the connecting hole 311 and is connected to the heating component 2 and the thermocouple. The end face of the metal conductor 33 is connected to the battery component.

[0027] Specifically, the top of the fixing part 32 is higher than the second housing 31. After the metal conductor 33 is placed on the fixing part 32, it is squeezed and fixed by the first housing 1, thereby ensuring the stability of the connection between the metal conductor 33 and the connecting line 34. This avoids the problem of poor contact between the metal conductor 33 and the connecting line 34, which would prevent the heated cigarette device from being used.

[0028] It should be noted that there are multiple connecting wires 34, and the second ends of the multiple connecting wires 34 are respectively heating component 2 and thermocouple. The thermocouple is used to control the temperature of heating component 2 to prevent the heating component 2 from overheating and causing damage to the internal parts of the cigarette heating device. There are four connecting grooves 312, four fixing parts 32, and four metal conductors 33, which are respectively arranged on the four sides of the second housing 31.

[0029] During installation, the first end of the connecting wire 34 is placed on the fixing part 32, and the metal conductor 33 is inserted into the connecting groove 312. The connecting wire 34 is fixed by the fixing part 32 and the metal conductor 33, and the second end of the connecting wire 34 passes through the connecting hole 311 and is connected to the heating component 2 and the thermocouple. The end face of the metal conductor 33 is connected to the battery component, which makes the internal wiring connection of the heated cigarette device more convenient.

[0030] This application provides a connection hole 311 at the center of the second housing 31 and a connection groove 312 on the outer edge of the second housing 31. The fixing part 32 is disposed in the connection groove 312, and the metal conductor 33 is inserted into the connection groove 312 and engaged with the fixing part 32. The first end of the connecting wire 34 is located between the fixing part 32 and the metal conductor 33, and the second end of the connecting wire 34 passes through the connection hole 311 and is connected to the heating component 2 and the thermocouple. The end face of the metal conductor 33 is connected to the battery assembly. During installation, the first end of the connecting wire 34 is placed on the fixing part 32, and the metal conductor 33 is inserted into the connecting groove 312. The connecting wire 34 is fixed by the fixing part 32 and the metal conductor 33, and the second end of the connecting wire 34 passes through the connecting hole 311 and connects to the heating component 2 and the thermocouple. The end face of the metal conductor 33 is connected to the battery component, which makes the internal wiring connection of the heated cigarette device more convenient, reduces the processing difficulty of the heated cigarette device, and has a simple structure, is easy to operate, saves time and effort in the assembly process, and improves work efficiency.

[0031] Furthermore, the conductive component 3 also includes a limiting ring 37, which is disposed on the top of the second housing 31 and connected to the connecting hole 311. The diameter of the limiting ring 37 is equal to the diameter of the connecting hole 311. A notch 38 is provided on the limiting ring 37, and the second end of the connecting wire 34 passes through the notch 38 and the connecting hole 311 in sequence to connect with the heating component 2 and the thermocouple, thereby providing a limiting effect on the connecting wire 34 and preventing the connecting wire 34 from moving during use, which would cause the connecting wire 34 to disconnect from the heating component 2, the thermocouple and the battery assembly.

[0032] In one embodiment of the heated cigarette device of this application, as shown in Figures 2 to 4, the connecting groove 312 has a convex structure.

[0033] The fixing part 32 includes a transverse protrusion 321, a first vertical protrusion 322, and a second vertical protrusion 323. The two sides of the transverse protrusion 321 are perpendicularly connected to the first end of the first vertical protrusion 322 and the first end of the second vertical protrusion 323, respectively. The second end of the first vertical protrusion 322 is at the same height as the end face of the second housing 31.

[0034] This application sets the connecting groove 312 as a convex structure, and makes the two sides of the transverse protrusion 321 perpendicularly connected to the first end of the first vertical protrusion 322 and the first end of the second vertical protrusion 323 respectively. The second end of the first vertical protrusion 322 is higher than the end face of the second housing 31. As a result, the metal conductor 33 is not easy to move after being placed in the connecting groove 312 and the fixing part 32, thus ensuring the stability of the metal conductor 33 fixed on the second housing 31. Furthermore, the process of installing the metal conductor 33 is relatively simple, effectively improving work efficiency.

[0035] In one embodiment of the heated cigarette device of this application, as shown in Figures 2 to 4, the second end of the first vertical protrusion 322 is provided with a mounting groove 324, and the first end of the connecting line 34 is provided in the mounting groove 324.

[0036] Specifically, the depth of the mounting groove 324 is less than the diameter of the connecting wire 34, so that after the connecting wire 34 is placed in the mounting groove 324, part of the connecting wire 34 is located above the mounting groove 324, which can ensure that the metal conductor 33 and the connecting wire 34 are in close contact.

[0037] This application ensures the stability of the contact between the connecting wire 34 and the metal conductor 33 by providing a mounting groove 324 at the second end of the first vertical protrusion 322 and placing the first end of the connecting wire 34 in the mounting groove 324.

[0038] In one embodiment of the heated cigarette device of this application, as shown in FIG3, the width of the vertical section of the first vertical protrusion 322 is greater than the width of the vertical section of the transverse protrusion 321, and the width of the vertical section of the transverse protrusion 321 is greater than the width of the vertical section of the second vertical protrusion 323.

[0039] This application further ensures the stability of the contact between the connecting line 34 and the metal conductor 33 by setting the width of the vertical section of the first vertical protrusion 322 to be greater than the width of the vertical section of the horizontal protrusion 321, and setting the width of the vertical section of the horizontal protrusion 321 to be greater than the width of the vertical section of the second vertical protrusion 323.

[0040] In one embodiment of the heated cigarette device of this application, as shown in FIG4, the metal conductor 33 includes a first metal sleeve 331, a second metal sleeve 332 and a third metal sleeve 333. The first metal sleeve 331 is sleeved on the second end of the first vertical protrusion 322. The second metal sleeve 332 and the third metal sleeve 333 are respectively sleeved on the two ends of the horizontal protrusion 321. The first ends of the second metal sleeve 332 and the third metal sleeve 333 are respectively connected to the two ends of the first metal sleeve 331. The second ends of the second metal sleeve 332 and the third metal sleeve 333 abut against the two side walls of the second vertical protrusion 323.

[0041] Specifically, the second metal sleeve 332 has elastic deformation, which allows the distance between the metal conductor 33 and the end of the first vertical protrusion 322 to change, thereby adapting to different types of connecting wires 34.

[0042] This application, by fitting a first metal sleeve 331 onto the second end of a first vertical protrusion 322, and fitting a second metal sleeve 332 and a third metal sleeve 333 onto the two ends of a horizontal protrusion 321 respectively, with the first ends of the second metal sleeve 332 and the third metal sleeve 333 respectively connected to the two ends of the first metal sleeve 331, and the second ends of the second metal sleeve 332 and the third metal sleeve 333 respectively abutting against the two side walls of the second vertical protrusion 323, enables the entire first metal sleeve 331, second metal sleeve 332 and third metal sleeve 333 to not form a closed circuit, thereby providing conductivity, and also enabling the first metal sleeve 331 to stably fix the connecting wire 34.

[0043] In one embodiment of the heated cigarette device of this application, as shown in FIG1, a plurality of through holes 11 are provided on the first end of the first housing 1, and at least a portion of the first metal sleeve plate 331 and the first vertical protrusion 322 are located in the through holes 11.

[0044] This application provides a limiting effect on the first metal sleeve 331 and the first vertical protrusion 322 by providing a plurality of through holes 11 at the first end of the first housing 1 and placing at least a portion of the first metal sleeve 331 and the first vertical protrusion 322 within the through holes 11, thereby ensuring the tightness of the contact between the first metal sleeve 331 and the connecting line 34.

[0045] In one embodiment of the heated cigarette device of this application, as shown in Figures 2 to 4, a limiting protrusion 12 is provided on the inner wall of the first housing 1.

[0046] The conductive component 3 also includes a connecting block 35, the first end of which is connected to the second housing 31. A limiting groove 36 is provided on the connecting block 35, and the limiting protrusion 12 is inserted into the limiting groove 36.

[0047] This application provides a limiting protrusion 12 on the inner wall of the first housing 1 and connects the first end of the connecting block 35 to the second housing 31. The limiting protrusion 12 is inserted into the limiting groove 36, thereby ensuring the stability of the connection between the conductive component 3 and the second housing 31.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
