E-Cigarette Vent Hole Structure for Unblocked E-Liquid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarettes face issues with e-liquid refilling pressure and pipe blockage due to condensed e-liquid during use.
Innovation Solution
The electronic cigarette design incorporates a silica seal with a vent hole in the atomization assembly and a hollow heating tube that communicates with the pneumatic switch, allowing e-liquid to penetrate and release bubbles, preventing blockages, and ensuring efficient heating and vaporization without extra pressure during refilling and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If e-liquid is refilled into the atomizer, then the atomizer can be replenished with e-liquid, but bubbles are generated during penetration which may block the e-liquid channel
Solution Approach 1:
The patent extracts the harmful element (bubbles) from the system by providing a dedicated escape path through the vent hole in the silica seal, allowing bubbles to be removed from the e-liquid channel during refilling, thus preventing blockages while maintaining reliable e-liquid delivery
Solution Approach 2:
The silica seal with vent hole acts as an intermediary component between the refilling process and the e-liquid channel, mediating the entry of e-liquid while providing a separate pathway for bubble escape, thus resolving the contradiction between refilling capability and channel reliability
2Reliability
If condensed e-liquid blocks the conveying pipe, then vaporization is disrupted, but continuous heating is required to maintain vapor flow
Solution Approach 1:
The patent employs periodic thermal action where the heating tube periodically heats the ceramic core to vaporize condensed e-liquid in the conveying pipe, creating a cyclic clearing action that maintains vaporization continuity without requiring constant high-energy input, thus resolving the contradiction between reliability and energy consumption
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the refilling process by eliminating the need for extra pressure and prevents pipe blockages by maintaining the e-liquid in a free state, ensuring smooth operation and easy maintenance.
Implementation Method 1
The bubbles can release from the vent hole thus preventing the blockage of the e-liquid channel
Implementation Method 2
the thermal vapor flow can enter the heating tube to drive the pneumatic switch to work and heat the ceramic core, so that the e-liquid in the atomization assembly is heated to a free state, thus preventing the blockage of the conveying pipe by the condensed e-liquid
