Solution Overview
Problem
Existing electronic cigarettes suffer from liquor condensate accumulation, which affects taste and user experience, and can lead to corrosion of the circuit board, reducing the device's service life.
Innovation Solution
The atomizer features a porous heating element with a porous body and boss that integrates e-liquid guiding and heating functions, preventing liquor condensate leakage and facilitating secondary atomization, while maintaining a simple assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If e-liquid is exported through the e-liquid guiding hole to the atomization component, then the atomization function is achieved, but liquor condensate accumulates on wall surfaces and penetrates into the battery host causing corrosion
Solution Approach 1:
The patent extracts the harmful liquor condensate from the system by providing a drainage hole in the atomization component that directs condensate away from the battery host and circuit board, preventing corrosion and extending service life
Solution Approach 2:
The patent introduces a drainage hole as an intermediary pathway that mediates between the atomization chamber and the external environment, allowing harmful condensate to be safely evacuated without affecting the battery host or circuit board
2Ease of manufacture
If a ceramic heating element covered with cotton is used to heat e-liquid, then atomization is achieved, but the structure becomes complex and assembly is difficult
Solution Approach 1:
The patent merges the heating element and atomization component into a single integrated unit, eliminating the need for separate cotton covering and multiple assembly steps, thereby simplifying both manufacturing and assembly processes
Solution Approach 2:
The atomization component serves multiple functions simultaneously: it acts as both the heating element support and the atomization surface, while also incorporating the drainage hole for condensate removal, reducing the overall number of components needed
3Ease of operation
If the atomization component is powered on to generate high-temperature atomized e-liquid, then smoking function is achieved, but droplets remain in the atomizer and mix with adsorbed e-liquid forming liquor condensate
Solution Approach 1:
The patent extracts accumulated liquor condensate from the atomizer through the drainage hole, preventing it from mixing with fresh e-liquid and degrading user experience, thereby maintaining consistent taste quality during operation
