Description

Technical Field

[0001] The utility model relates to the technical field of tobacco heating, and more specifically, to a cigarette heating device. Background Art

[0002] Products in which tobacco-containing aroma-producing materials are heated at a temperature of about 350°C instead of being burned are well known in the art. These products can be called heated smoking products. Heated smoking products have a similar appearance to traditional cigarettes. They release substances such as aroma components in the aroma-producing materials through electric heating or other heating methods to produce inhalable aerosols, thereby avoiding the generation of a large number of harmful components due to high-temperature cracking. While smokers gain satisfaction, they reduce harm to the human body and reduce environmental smoke pollution. Heated smoking products require smoking utensils, which use electric heating of the smoking utensils to make the smoking products reach the required smoking temperature.

[0003] At present, in order to ensure the stability of the resistance value of the existing heating cigarette device, the circuit is usually fixed by welding. The resistance value of the circuit is stable through welding, which is convenient for temperature control.

[0031] The conductive component 3 includes a second shell 31, a fixing portion 32, a metal conductor 33 and a connecting wire 34; a connecting hole 311 is provided at the center of the second shell 31 and a connecting groove 312 is provided at the outer edge of the second shell 31, the fixing portion 32 is provided in the connecting groove 312, and the metal conductor 33 is inserted into the connecting groove 312 and is clamped with the connecting groove 312 and the fixing portion 32, the first end of the connecting wire 34 is located between the fixing portion 32 and the metal conductor 33, 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, and the end face of the metal conductor 33 is connected to the battery assembly.

[0032] Specifically, the height of the top of the fixing portion 32 is higher than that of the second shell 31, so that after the metal conductor 33 is placed on the fixing portion 32, the connecting wire 34 between the fixing portion 32 and the metal conductor 33 is squeezed and fixed by being squeezed with the first shell 1, thereby ensuring the stability of the connection between the metal conductor 33 and the connecting wire 34, and avoiding the problem of poor contact between the metal conductor 33 and the connecting wire 34, which makes the heating cigarette device unusable.

[0033] It should be noted that there are multiple connecting wires 34, and the second ends of the multiple connecting wires 34 are respectively connected to the heating component 2 and the thermocouple, and the thermocouple is used to control the temperature of the heating component 2 to avoid the problem that the temperature of the heating component 2 is too high and causes damage to the internal part of the heating cigarette device. There are four connecting grooves 312, fixing parts 32, and metal conductors 33, which are respectively arranged on the four sides of the second shell 31.

[0034] During the installation process, 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 to connect with the heating component 2 and the thermocouple, and the end face of the metal conductor 33 is connected to the battery assembly, thereby making the internal circuit connection of the heating cigarette device more convenient.

[0035] The utility model provides a connection hole 311 at the center of the second shell 31 and a connection groove 312 at the outer edge of the second shell 31, the fixing portion 32 is arranged in the connection groove 312, and the metal conductor 33 is inserted into the connection groove 312 and clamped with the connection groove 312 and the fixing portion 32, the first end of the connecting wire 34 is located between the fixing portion 32 and the metal conductor 33, 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, and the end face of the metal conductor 33 is connected to the battery assembly.

[0037] In one embodiment of the cigarette heating device of the utility model, as Figures 2 to 4 As shown, the connection groove 312 is a convex structure.

[0038] The fixing portion 32 includes a lateral protrusion 321 , a first vertical protrusion 322 and a second vertical protrusion 323 . Both sides of the lateral protrusion 321 are vertically 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 a height of the end surface of the second shell 31 .

[0042] The utility model provides a mounting groove 324 at the second end of the first vertical protrusion 322 , and arranges the first end of the connecting wire 34 in the mounting groove 324 , thereby ensuring the stability of the contact between the connecting wire 34 and the metal conductor 33 .

[0046] Specifically, the second metal sleeve plate 332 has elastic deformation, so that the distance between the metal conductor 33 and the end of the first vertical protrusion 322 can be changed, thereby being able to adapt to different types of connecting wires 34 .

[0047] The utility model arranges the first metal sleeve 331 on the second end of the first vertical protrusion 322, and the second metal sleeve 332 and the third metal sleeve 333 are respectively arranged on the two ends of the horizontal protrusion 321, and the first end of the second metal sleeve 332 and the first end of the third metal sleeve 333 are respectively connected to the two ends of the first metal sleeve 331, and the second end of the second metal sleeve 332 and the second end of the third metal sleeve 333 are respectively abutted against the two side walls of the second vertical protrusion 323, so that the entire first metal sleeve 331, the second metal sleeve 332 and the third metal sleeve 333 do not form a closed loop, thereby providing a conductive effect, and at the same time, the first metal sleeve 331 can stably fix the connecting line 34.
