Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers in electronic cigarettes suffer from issues such as burnt flavor generation, metal pollution, and reduced atomization efficiency due to heating wire exposure and embedding, leading to smaller aerosol particles and decreased throat hit.
Innovation Solution
A cartridge design featuring a heating element embedded in a micro-porous body with through holes, where the heating element is partially embedded and positioned to promote aerosol oscillation and fusion, utilizing micro-porous bodies with different heat conductive rates and porosities to enhance aerosol particle size and quantity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the heating wire is embedded in the micro-porous body, then dry burn and metal pollution are eliminated, but the heat is absorbed and conducted more rapidly causing reduced atomizing efficiency and aerosol amount
Solution Approach 1:
The patent applies local quality by creating distinct regions within the micro-porous body: a first micro-porous body with higher heat conductive rate for rapid heat dissipation away from the heating element, and a second micro-porous body with lower heat conductive rate for maintaining atomization temperature. This spatial differentiation of thermal properties resolves the contradiction between preventing dry burn and maintaining atomizing efficiency.
Solution Approach 2:
The micro-porous body is segmented into two functional parts: a first micro-porous body for heat conduction and a second micro-porous body for atomization. This segmentation allows each part to perform its specific function optimally, preventing the heating element from direct contact with external environment while maintaining proper temperature for vaporization.
2Reliability
If the heating wire is embedded deeper in the micro-porous body, then dry burn is prevented, but the amount of tobacco liquid contacting the heating wire decreases reducing atomizing efficiency
Solution Approach 1:
The first micro-porous body acts as an intermediary between the heating element and the external environment. It conducts heat away from the heating element rapidly, preventing dry burn, while the second micro-porous body with lower heat conduction maintains the necessary temperature for efficient atomization. This intermediary structure allows the heating element to be embedded without direct harmful effects.

Function Achieved in This Case
The design prevents dry burn and metal pollution while increasing aerosol particle size and throat hit, improving atomization efficiency and aerosol amount by optimizing heat distribution and liquid contact.
Implementation Method 1
the liquid conductive element absorbs tobacco liquid by a surface of the liquid conductive element contacting a reservoir formed in the atomizer to absorb the tobacco liquid then conducted to the heating wire via micro-pores therein
Implementation Method 2
the heating wire is embedded into the main body of power metallurgy... heated by the heating wire to form an aerosol
Implementation Method 3
A heat conductive rate of the first micro-porous body is higher than that of the second micro-porous body
