Vaporizer Vent Cap Grooves for Condensate Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensate forms on the side walls of the gas delivery channel in electronic vaporization devices, leading to a poor user experience as it is inhaled along with vapor.
Innovation Solution
A vaporizer design featuring a liquid storage shell with a vent hole and a liquid absorbing member, equipped with liquid guide grooves on the end cap to direct condensate away from the vent hole and into the absorbing member, enhancing absorption efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vapor is delivered through the gas delivery channel, then the user can inhale vapor, but condensate forms on the side wall and is inhaled by the user, affecting user experience
Solution Approach 1:
The patent extracts the harmful condensate from the vapor flow path by introducing a separate liquid discharge channel that runs parallel to but independent from the gas delivery channel. This allows condensate to be removed from the system without interfering with vapor delivery to the user.
Solution Approach 2:
The patent segments the fluid transport system into distinct channels: a gas delivery channel for vapor and a separate liquid discharge channel for condensate. This segmentation prevents mixing of vapor and condensate, allowing each to be managed independently to eliminate harmful inhalation.
2Reliability
If a liquid absorbing member is placed at the vent hole, then condensate can be absorbed, but the absorption speed is insufficient without proper liquid guidance
Solution Approach 1:
The patent introduces liquid guide grooves as intermediary structures that channel condensate from the vent hole directly to the liquid absorbing member. These grooves act as mediators that accelerate the transfer of condensate to the absorption material, significantly improving absorption speed and reliability.
Solution Approach 2:
The patent utilizes capillary action and surface tension (hydraulic principles) through the liquid guide grooves to actively transport condensate toward the absorbing member without requiring external power sources. The groove geometry is designed to optimize fluid flow characteristics for efficient condensate removal.

Function Achieved in This Case
The solution effectively guides and absorbs condensate, improving user experience by preventing its inhalation and increasing the absorption speed of the liquid absorbing member.
Implementation Method 1

AI summary
A vaporizer includes: a liquid storage shell, a liquid storage space and an airflow channel being formed within the liquid storage shell; an end cap covering one end of the liquid storage space, a vent hole in communication with the airflow channel being formed on the end cap; and a liquid absorbing member arranged on the end cap, an air outlet hole in communication with the vent hole being formed on the liquid absorbing member. The end cap includes a supporting surface for contact with the liquid absorbing member. At least one first liquid guide groove is provided on the supporting surface. Each of the at least one first liquid guide groove comprises a first end in communication with the vent hole and a second end away from the vent hole.
