Embedded Planar Heater Wick for Higher Aerosol Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid vaporization-type aerosol generation devices face challenges in optimizing the combination structure of wicks and heating elements, leading to varying aerosol generation amounts and increased risk of wick damage, as well as inconsistencies in liquid transport speed and quantity.
Innovation Solution
A vaporizer design featuring a porous wick with a heating element embedded at a specific depth within the porous body, formed by ceramic beads, ensures uniform liquid transport and reduced wick damage, while a terminal is in close contact with the wick's side surfaces to minimize interference and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the heating element is positioned closer to the surface of the porous wick, then the aerosol generation amount increases, but the risk of wick damage increases
Solution Approach 1:
The patent optimizes the embedding depth parameter of the heating element within the porous wick, specifying a range of 0-400 μm from the surface. This parameter adjustment allows the heating element to be positioned close enough to the surface for effective aerosol generation while remaining embedded sufficiently deep to avoid direct exposure and damage, thus resolving the contradiction between productivity and reliability
Solution Approach 2:
The heating element is nested within the porous wick structure rather than being placed on the surface. This nesting approach allows the heating element to be embedded at an optimal depth (0-400 μm), protecting it from damage while maintaining close proximity to the wick surface for efficient heat transfer and aerosol generation
2Volume of moving object
If the terminal is disposed to come in close contact with the side surface of the porous body, then the device compactness increases, but the interference with airflow may occur
Solution Approach 1:
The terminal is positioned to contact only the side surface of the porous wick body at a specific location, rather than occupying central or airflow-critical areas. This localized placement minimizes the terminal's interference with airflow paths while achieving compact device integration

AI summary
Provided herein are a vaporizer and an aerosol generation device including the same. The vaporizer according to some embodiments of the present disclosure includes a porous wick configured to absorb an aerosol-generating substrate in a liquid state through a porous body, and a heating element which includes a heating pattern having a planar form that is embedded in the porous body and which is configured to heat the absorbed aerosol-generating substrate by the heating pattern to generate an aerosol. Since the heating pattern is embedded at a predetermined depth from a surface of the porous body, the amount of generated aerosol may be increased, and the risk of damage to the wick and the carbonization phenomenon may be reduced.
