Definitions

  • Heat-not-burn aerosol generation devices are gaining increasing attention and favor due to their advantages of safety, convenience, health, and environmental friendliness. These devices generate aerosol by heating and baking various forms of aerosol generation substrates and deliver the aerosol to users for inhalation. This "heat-not-burn" method ensures that the aerosol generation substrate is heated at a relatively low temperature without combustion and without producing an open flame, effectively avoiding the generation of harmful substances caused by the aerosol generation substrate.
  • the objective of the present application is to provide a heating assembly that forms relatively independent heating zones to avoid excessively high heating temperatures that produce high-temperature aerosol, thereby improving user experience.
  • the present application aims to provide an aerosol generation device using the aforementioned heating assembly.
  • an embodiment provides a heating assembly including a heating element configured to heat an aerosol generation substrate, where the heating element includes at least two heating zones.
  • a thermal barrier structure is provided between at least one pair of adjacent heating zones, the thermal barrier structure being configured to reduce heat transfer between the adjacent heating zones.
  • the heating element includes at least two heating zones, and a thermal barrier structure is provided between at least one pair of adjacent heating zones.
  • the thermal barrier structure is used to prevent heat conduction between adjacent heating zones, reducing the heat transfer speed between different heating zones, improving the thermal insulation performance between adjacent heating zones, and forming relatively independent heating zones between adjacent heating zones. This allows for selective heating of the heating zones as needed, thereby helping to reduce the overall temperature of the heating element and consequently lowering the temperature of the aerosol generated by the aerosol generation substrate, improving user experience.
  • the heating element uses an insulating body embedded in the heat-insulating zone to separate different heating zones, employing physical blocking to prevent heat transfer between the heating zones.
  • the heating element heats a certain heating zone, the heat transfer from that heating zone to other heating zones is reduced, achieving localized heating of the aerosol generation substrate.
  • local heating can be controlled, and the temperature of the aerosol will not be too high, allowing the user to feel a lower temperature during the first few puffs, reducing the risk of burning the mouth and improving user experience.
  • the heating element includes a heating pipe configured to heat the aerosol generation substrate.
  • the pipe wall of the heating pipe includes at least two heating zones, each capable of heating the aerosol generation substrate.

  • the heating zones form the heating zones, and the thermal insulation interval forms the thermal barrier structure.
  • the heating assembly includes a thermoplastic sealing layer provided on the heating pipe and covering the thermal insulation interval to prevent airflow within the heating pipe from flowing out through the thermal insulation interval.
  • the thermal insulation interval is used to prevent heat conduction between adjacent heating zones, reducing the heat transfer speed between different heating zones. Consequently, when the heating requirements of adjacent heating zones differ, mutual influence is minimized, and heat loss is reduced. Meanwhile, by covering the thermal insulation interval with a thermoplastic sealing layer, airflow within the heating pipe is prevented from flowing out through the thermal insulation interval, further reducing heat loss.
  • the heating element includes a thermally conductive pipe and electric heating elements provided on the thermally conductive pipe.

  • the heating zones form the heating zones, and the pipe wall thinning portion forms the thermal barrier structure.
  • the pipe wall thinning portion slows down the heat transfer speed between adjacent heating zones.
  • the heat is more concentrated in the heated area of the working heating zone, resulting in higher heat utilization efficiency, less heat loss, and improved independent heating efficiency of the heating zones.
  • connection and “couple” in the present application, unless otherwise specified, include both direct and indirect connections (couplings).
  • the heating assembly includes a heating element configured to heat an aerosol generation substrate, and the heating element includes at least two heating zones.

In actual use, it is not limited to only the first heating zone 30241 or only the second heating zone 30242 being turned on for heating. According to actual needs, the first heating zone 30241 and the second heating zone 30242 can be turned on for heating at the same time, in which case the heating pipe 302 as a whole heats the aerosol generation substrate 301.
  • a heating strategy for the aerosol generation substrate 301 is as follows.
  • the aerosol generated after heating contains water vapor. If the temperature of the aerosol is too high at this time, the water vapor can easily burn the mouth when inhaling the aerosol. Therefore, when starting to heat the aerosol generation substrate 301, only the first heating zone 30241 is used to heat the aerosol generation substrate 301. After the moisture in the aerosol generation substrate 301 is expelled, the first heating zone 30241 and the second heating zone 30242 work simultaneously, and the heating pipe 302 as a whole heats the aerosol generation substrate 301.
  • a heating strategy for the aerosol generation substrate 301 is as follows: arrange the first heating zone 30241 and the second heating zone 30242 vertically, with the first heating zone 30241 heating one section of the aerosol generation substrate 301, and then the second heating zone 30242 heating another section of the aerosol generation substrate 301.
  • the first heating zone 30241 and the second heating zone 30242 work in different time periods to heat the aerosol generation substrate 301 in sections, which can extend the number of puffs of the aerosol generation substrate 301.
  • the outer side surface of the pipe wall thinning portion 3028 is recessed toward the inside of the heating pipe 302. In some other embodiments, the inner side surface of the pipe wall thinning portion 3028 is recessed toward the outside of the heating pipe 302. In some other embodiments, the outer side surface of the pipe wall thinning portion 3028 is recessed toward the inside of the heating pipe 302, and the inner side surface of the pipe wall thinning portion 3028 is recessed toward the outside of the heating pipe 302.
  • the first heating zone 30241 and the second heating zone 30242 are arranged adjacent to each other in the circumferential direction of the heating pipe 302, with the pipe wall thinning portion 3028 extending along the axial direction of the heating pipe 302.
  • the arrangement of heating zones 3024 on the heating pipe 302 can use any feasible form.
  • the first heating zone 30241 and the second heating zone 30242 can also be arranged adjacent to each other in the axial direction of the heating pipe 302, with the pipe wall thinning portion 3028 extending along the circumferential direction of the heating pipe 302.
  • there are four or more heating zones 3024 with at least two arranged adjacent to each other in the circumferential direction of the heating pipe 302 and at least two arranged adjacent to each other in the axial direction of the heating pipe 302.
  • the blocking edge 3053 is clamped between the heating pipe 302 and the second heating pipe seat 308.
