HEATER ASSEMBLY FOR USE IN AN AEROSOL-GENERATING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240032599 titled 'HEATER ASSEMBLY FOR USE IN AN AEROSOL-GENERATING SYSTEM

Simplified Explanation

The abstract describes a heater assembly for an aerosol-generating system. The assembly includes a retention material that contains an aerosol-forming substrate in condensed form. The aerosol-forming substrate consists of two compounds, with the second compound having a higher boiling point than the first compound. The assembly also includes at least one airflow path defined through the retention material and at least one heating element. The heating element is shaped to define an interior volume filled with the retention material, and its cross-sectional area decreases along a longitudinal axis. The airflow path passes through a first central region and a second central region of the interior volume, which are spaced-apart along the longitudinal axis. The resistance of the heating element increases along the longitudinal axis in the same direction that the cross-sectional area of the interior volume decreases.

  • The heater assembly is designed for an aerosol-generating system.
  • It includes a retention material that contains an aerosol-forming substrate in condensed form.
  • The aerosol-forming substrate consists of two compounds, with the second compound having a higher boiling point than the first compound.
  • The assembly has at least one airflow path defined through the retention material.
  • It also includes at least one heating element that is shaped to define an interior volume filled with the retention material.
  • The cross-sectional area of the heating element decreases along a longitudinal axis.
  • The airflow path passes through a first central region and a second central region of the interior volume, which are spaced-apart along the longitudinal axis.
  • The resistance of the heating element increases along the longitudinal axis in the same direction that the cross-sectional area of the interior volume decreases.

Potential Applications

  • Aerosol-generating systems for various industries such as pharmaceuticals, personal care, and household products.
  • Inhalation devices for medical treatments and therapies.
  • Air fresheners and scent diffusers.
  • Electronic cigarettes and vaping devices.

Problems Solved

  • Efficient and controlled aerosol generation.
  • Enhanced vaporization of the aerosol-forming substrate.
  • Improved heat distribution and airflow through the retention material.
  • Prevention of clogging or blockage in the airflow path.

Benefits

  • Consistent and reliable aerosol generation.
  • Increased efficiency and effectiveness of aerosol-based products.
  • Improved user experience with inhalation devices.
  • Reduced risk of overheating or damage to the heating element.
  • Enhanced safety and reliability of the aerosol-generating system.


Original Abstract Submitted

a heater assembly for an aerosol-generating system is provided, the heater assembly including: a retention material containing an aerosol-forming substrate in condensed form, the aerosol-forming substrate including first and second compounds, the second compound having a higher boiling point than the first compound; at least one airflow path defined through the retention material; and at least one heating element shaped to define an interior volume filled with the retention material and having a cross-sectional area that decreases along a longitudinal axis, the at least one airflow path passes through a first central region of the interior volume and a second central region of the interior volume, the first and the second central regions being spaced-apart along the longitudinal axis, and a resistance of the at least one heating element increasing along the longitudinal axis in a same direction that the cross-sectional area of the interior volume decreases.
