Solution Overview
Problem
Electronic vaporization apparatuses face issues of 'e-liquid explosion' and 'burnt core' due to excessive or insufficient e-liquid content in the porous substrate, affecting user experience and device longevity.
Innovation Solution
A vaporization core design with a porous substrate featuring a liquid penetration portion and a temporary liquid storage portion, where the volume of e-liquid stored, vaporized, and entering the substrate is controlled to maintain an appropriate balance, ensuring continuous operation without e-liquid explosion or burnt core through specific volume and porosity calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the e-liquid content in the porous substrate is increased, then the vaporization duration is extended, but e-liquid explosion and leakage occur
Solution Approach 1:
The porous substrate is divided into two functional regions: a liquid penetration portion for e-liquid supply and a temporary liquid storage portion for controlled e-liquid retention. This segmentation allows the system to hold sufficient e-liquid for extended vaporization while preventing excessive accumulation that causes explosion and leakage.
2Object-affected harmful factors
If the e-liquid content in the porous substrate is decreased, then e-liquid explosion and leakage are prevented, but burnt core occurs
Solution Approach 1:
The temporary liquid storage portion pre-stores a controlled amount of e-liquid before vaporization begins. This preliminary e-liquid preparation ensures that sufficient liquid is available at the vaporization surface from the start, preventing the burnt core phenomenon while the controlled storage capacity prevents excessive accumulation.
3Quantity of substance
If the porous substrate volume is increased, then the e-liquid storage capacity is improved, but the device size increases
Solution Approach 1:
Different regions of the porous substrate are assigned different functions and properties: the liquid penetration portion has optimized porosity for e-liquid transport, while the temporary liquid storage portion has optimized porosity for e-liquid retention. This local differentiation maximizes e-liquid storage capacity within a compact overall device volume.

AI summary
An electronic vaporization apparatus includes a vaporization core, and the vaporization core includes a porous substrate and a heating element, where the porous substrate includes a liquid absorbing surface and a vaporization surface, and the heating element is arranged on the vaporization surface. The porous substrate is defined to include a liquid penetration portion and a temporary liquid storage portion that are connected, the temporary liquid storage portion is close to the vaporization surface and the temporary liquid storage portion is a portion of a volume of the porous substrate occupied by e-liquid with a maximum vaporizable volume Qc1 in an inhalation cycle of the vaporization core. In any inhalation cycle of continuous inhalations, the vaporization core meets: Qcn ≥ Qxn ≥ Qbn, where Qcn represents a volume of e-liquid stored in the temporary liquid storage portion before an nth inhalation cycle starts, Qxn represents a volume of e-liquid actually vaporized during the nth inhalation cycle, and Qbn represents a volume of e-liquid entering the porous substrate during the nth inhalation cycle.
