Solution Overview
Problem
Existing electronic vaporization devices face issues with limited condensate storage in vent grooves, leading to pressure fluctuations and liquid feeding disruptions due to liquid absorption back into the storage cavity during suction.

A vaporizer design featuring a vent channel with a vent entrance and a liquid absorbing groove opening, utilizing capillary forces to isolate ventilation from liquid storage, preventing liquid blockage and maintaining stable air pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a vent groove is provided in the vaporizer to balance air pressure in the liquid storage cavity, then air pressure balance is improved, but the vent groove fills with liquid causing pressure fluctuation and affecting liquid feeding
Solution Approach 1:
The vent groove is segmented into two functional zones: a first portion for air pressure balancing and a second portion (liquid storage groove) for liquid accommodation. This segmentation allows the vent groove to independently perform both functions without mutual interference, resolving the contradiction between air pressure stability and liquid feeding reliability.
Solution Approach 2:
The liquid absorbing body acts as an intermediary between the liquid storage groove and the liquid storage cavity. It absorbs excess liquid from the first portion of the vent groove through capillary action, preventing liquid from blocking the air pressure balancing function while maintaining reliable liquid feeding to the heating element.
2Quantity of substance
If the vent groove is filled with liquid, then liquid storage capacity is improved, but liquid is absorbed back to the liquid storage cavity causing pressure fluctuation
Solution Approach 1:
Different portions of the vent groove are assigned different functions: the first portion stores condensate while the second portion (liquid storage groove) provides capillary absorption. The liquid absorbing body creates a local quality difference that enables selective liquid absorption from the first portion without disrupting pressure stability in the liquid storage cavity.
3Device complexity
If the vent groove is used for both ventilation and liquid storage, then device complexity is reduced, but liquid blocks the vent channel causing ventilation failure
Solution Approach 1:
The vent groove is divided into a first portion for ventilation and a second portion (liquid storage groove) for liquid storage. The liquid absorbing body creates a functional barrier that prevents liquid from the first portion from blocking the ventilation path, allowing the single integrated structure to reliably perform both ventilation and liquid storage functions.
Solution Approach 2:
The liquid absorbing body automatically absorbs excess liquid from the vent groove through capillary action without requiring external control mechanisms. This self-service function maintains ventilation reliability by preventing liquid blockage while keeping the device structure simple and integrated.
