E-Liquid Tasting Device Using Venturi Tube for Droplet-Free Puffs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing e-liquid tasting devices provide unsatisfactory puffs and are inefficient in delivering a quality experience akin to real e-cigarette puffs, and existing solutions for tasting multiple flavors are either costly or impractical for retailers.
Innovation Solution
A device utilizing a Venturi tube to generate e-liquid vapors by connecting an airflow generator to an e-liquid vaporizer, with a power source and a switch mechanism, ensuring the airflow does not pass through the vaporizer, and incorporating a presence sensor and time-limiting mechanisms to enhance puff quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the airflow passes through the e-liquid vaporizer to deliver vapor, then the user receives e-liquid vapor, but the puff contains droplets and the quality is unsatisfactory
Solution Approach 1:
The patent extracts the harmful function (airflow passing through vaporizer causing droplet generation) by separating the vaporization chamber from the airflow path. The airflow generator draws air through the Venturi tube without passing through the vaporizer, while vapor is separately introduced into the airflow path, eliminating droplet contamination.
Solution Approach 2:
The patent introduces a Venturi tube as an intermediary device that mediates between the airflow generator and the user's mouth. The Venturi tube creates a low-pressure zone that draws vapor from the vaporizer into the airflow without requiring the airflow to pass through the vaporizer itself, thus preventing droplet formation while maintaining vapor delivery.
2Adaptability or versatility
If multiple clearomizers are used to taste different flavors, then flavor variety is available, but the device complexity and cost increase
Solution Approach 1:
The patent makes the airflow generator and Venturi tube universal components that can work with multiple different clearomizers. The airflow path and vaporization chamber are designed to accommodate various clearomizer types, allowing users to taste multiple flavors by simply changing the clearomizer while using the same core device structure.
Solution Approach 2:
The patent segments the device into modular components: a reusable core unit (airflow generator, Venturi tube, housing) and replaceable clearomizers. This segmentation allows the complex airflow generation system to be separated from the flavor-specific clearomizers, reducing overall device complexity while maintaining flavor variety.
3Ease of operation
If the switch controls both airflow generator and vaporizer, then operation is simplified, but accidental activation may occur
Solution Approach 1:
The patent incorporates a presence sensor that provides feedback about user presence to the control system. The switch only activates the vaporizer and airflow generator when the sensor detects that the user is present (mouthpiece positioned correctly), preventing accidental activation while maintaining simple switch operation.
