Liquid Guide Member for Condensate Management in Vaporizers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic vaporization devices suffer from the issue of condensate formation on the side walls of airflow channels during inhalation, leading to a liquid column that can be sucked into the suction nozzle, causing blockages and a poor user experience.
Innovation Solution
The vaporizer includes a liquid guide member arranged on the end of the first air outlet channel close to the vaporization cavity, which contacts and guides condensate into the vaporization cavity, breaking its surface tension and preventing blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heating is performed during inhalation, then aerosol generation is improved, but condensate formation on side walls increases causing blockages
Solution Approach 1:
The patent converts the harmful condensate into a beneficial resource by guiding it back to the vaporization cavity for secondary vaporization. The liquid guide member directs condensate along the inner wall of the air outlet channel back to the heating region, where it is re-vaporized and mixed with fresh aerosol, transforming the blockage problem into an enhanced vaporization process that improves atomization and reduces waste
Solution Approach 2:
The liquid guide member acts as an intermediary structure that mediates between the condensate formation on side walls and the vaporization cavity. It provides a controlled path for condensate to return to the heating region without directly blocking the air outlet, enabling the system to manage condensate flow and convert it into useful vaporized aerosol
2Reliability
If liquid guide member is added to guide condensate, then blockages are prevented, but device complexity increases
Solution Approach 1:
The liquid guide member is designed with local quality variations - it has a smooth inner wall surface that promotes condensate flow, and its position is specifically optimized within the air outlet channel. The guide member's geometry is tailored to match the local flow conditions and condensate accumulation patterns, enabling effective condensate redirection with minimal structural intervention
Solution Approach 2:
The liquid guide member is designed as a simple, easily manufacturable component that can be integrated into disposable vaping devices. Its straightforward geometry allows for cost-effective production and integration, making it suitable for single-use devices where complexity must be minimized while maintaining reliability
