Electronic Cigarette Atomizer Dry-Wet Separation Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette atomizers experience e-liquid leakage during high-temperature storage and low-pressure transportation due to increased fluidity and pressure changes, affecting their usability and user experience.
Innovation Solution
The atomizer incorporates a dry-wet separation component that can stretch and contract to control communication between the e-liquid storage chamber and the atomization component, preventing leakage by isolating them during transportation and re-establishing contact for atomization when in use, utilizing a movable rod and sealing sleeve mechanism within the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the atomizer is pre-filled with e-liquid for convenient use, then the ease of operation is improved, but e-liquid leakage occurs during high-temperature storage and low-pressure transportation
Solution Approach 1:
The atomizer is pre-filled with e-liquid before use, but a sealing structure is预先 installed to prevent leakage during storage and transportation. The sealing component is positioned in advance to block the liquid guiding hole, allowing the atomizer to be ready for use while preventing premature leakage.
Solution Approach 2:
A sealing component (such as a sealing ball or plug) is introduced as an intermediary element between the e-liquid storage chamber and the liquid guiding hole. This intermediary blocks the passage during storage and can be removed or moved during use, resolving the contradiction between pre-filling convenience and leakage prevention.
2Reliability
If the e-liquid storage chamber is sealed to prevent leakage, then the reliability is improved, but the atomization component cannot access e-liquid when needed
Solution Approach 1:
The sealing structure is designed to be dynamic rather than static. The sealing component can move between a blocking position (during storage) and an open position (during use). This dynamic characteristic allows the system to maintain reliability when sealed while ensuring ease of operation when the seal is activated.
Solution Approach 2:
The sealing structure is预先 configured to maintain the sealed state during storage, and the mechanism for opening the seal is prepared in advance. When the atomizer is put into use, the seal is activated (e.g., by user action or automatic mechanism) to allow e-liquid flow to the atomization component.
3Reliability
If a complex sealing mechanism is added to prevent leakage, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent employs simple, inexpensive sealing components such as sealing balls, plugs, or flaps that can be easily manufactured and integrated. These simple structures provide effective leakage prevention without adding significant complexity to the overall device.
Solution Approach 2:
Some sealing mechanisms are designed to operate automatically based on pressure differentials or gravitational forces. For example, a sealing ball may be pushed into place by pressure changes during storage and automatically move away when the atomizer is activated, eliminating the need for complex control mechanisms.
