Solution Overview
Problem
Existing aerosol generating apparatuses face issues where the temperature of hot air falling quickly due to heat exchange with the aerosol-generating product, leading to incomplete baking of the downstream part of the product and potential clogging from condensation.
Innovation Solution
A dual heating system is employed, comprising a first heating region to maintain the temperature of the aerosol-generating product and a second heating region to heat air flowing through a porous body, ensuring even heating and preventing temperature loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single heater is used to heat air through a porous body, then the structure is simple, but the temperature of hot air falls quickly due to heat exchange with the aerosol-generating product, leading to incomplete heating of downstream parts
Solution Approach 1:
The heater is divided into two independent heating regions: a first heating region that heats air before it enters the porous body, and a second heating region that maintains temperature of the aerosol-generating product during air flow through the porous body. This segmentation allows each region to perform its specific function optimally, preventing temperature drop while maintaining structural simplicity.
Solution Approach 2:
Different regions of the heater are designed with different heating functions tailored to local requirements: the first heating region focuses on heating incoming air to a high temperature, while the second heating region focuses on maintaining the temperature of the aerosol-generating product to prevent heat loss. This local differentiation solves the temperature drop problem without requiring a completely complex system.
2Device complexity
If the heater is arranged only on the tubular base body without electrical connections to the porous body, then the structure is simplified and the porous body is kept inside the tubular base body, but the heating effectiveness may be reduced
Solution Approach 1:
The tubular base body acts as an intermediary heat transfer medium. The first heating region heats the base body, which then transfers heat to the air passing through the porous body. The second heating region heats the base body in the region where the aerosol-generating product is located, maintaining its temperature. This intermediary approach eliminates the need for direct electrical connections to the porous body while maintaining heating effectiveness.
Solution Approach 2:
The patent replaces direct electrical heating of the porous body with a thermal field-based heating system. Instead of using electrical connections and resistive heating elements directly on the porous body, the system uses radiant and conductive heat transfer from the heated tubular base body to achieve the same heating effect, thereby simplifying the structure while maintaining reliability.

Function Achieved in This Case
The dual heating system ensures complete baking of the aerosol-generating product, reduces condensation, and prevents clogging, while eliminating the need for electrical connections to the porous body, maintaining a simple structure.
Implementation Method 1
a heater, arranged on a side surface of the tubular base body, where the heater includes a first heating region and a second heating region, the first heating region is correspondingly arranged on a periphery of the aerosol-generating product and is configured to heat or maintain a temperature of the aerosol-generating product, and the second heating region is correspondingly arranged on a periphery of the porous body and is configured to heat the porous body
Implementation Method 2
air enters the aerosol-generating product after passing through a pore inside the porous body; the second heating region heats the porous body, thereby heating air flowing through an inner part of the porous body to form hot air
Implementation Method 3
By using fluidity of air, after entering the aerosol-generating product, the hot air can be evenly distributed in the aerosol-generating product, so that the aerosol-generating product can be evenly baked
Implementation Method 4
the heater heats an aerosol-generating product to cause the aerosol-generating product to generate an aerosol
