Rotatable Liquid Blocking Element Prevents Atomizer Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol inhaling devices, such as electronic cigarette atomizers, suffer from liquid leakage due to gravity or shaking when not in use, as the tobacco liquid permeates and drops from the glass fiber core.
Innovation Solution
An atomizer design featuring a rotatable liquid blocking element with a notch that aligns with a liquid passage, allowing the tobacco liquid to flow to the atomizing component when in use, while preventing leakage by closing the passage when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the glass fiber core continuously absorbs tobacco liquid, then the atomizing component can generate aerosol efficiently, but liquid leakage occurs due to gravity or shaking when the device is not in use
Solution Approach 1:
The liquid blocking element is designed to be rotatable, transitioning between a first position (blocking liquid flow) and a second position (allowing liquid flow). This dynamic mechanism enables the system to adapt between storage mode (preventing leakage) and usage mode (enabling aerosol generation), resolving the contradiction between continuous liquid absorption and leakage prevention.
2Duration of action of moving object
If the liquid passage remains open for continuous liquid flow, then aerosol generation is maintained, but liquid drops and leaks from the glass fiber core
Solution Approach 1:
The liquid blocking element is positioned to preemptively block the liquid passage before leakage can occur. By applying counter-action (blocking) in advance during storage, the system prevents the harmful effect of liquid leakage while allowing continuous flow during active use when the blocker is rotated away.
3Reliability
If a liquid blocking element is added to control liquid flow, then leakage is prevented, but the device complexity increases
Solution Approach 1:
The liquid blocking element serves multiple functions: it blocks liquid flow during storage, allows liquid flow during use when rotated, and can be integrated with the existing atomizer structure. This multi-functionality reduces the need for separate components, thereby minimizing the increase in device complexity while achieving reliable leakage prevention.

AI summary
An exemplary atomizer (100) includes a main body (101), an atomizing component (106) received in the main body (101), and a liquid chamber (108) configured for receiving tobacco liquid. The atomizing component (106) is configured for generating aerosol from the tobacco liquid. The atomizing component (106) and the liquid chamber (108) cooperatively define a liquid passage (107) therebetween. The atomizer (100) further includes a liquid blocking element (104) defining a notch (105). The liquid blocking element (104) is capable of rotating relative to the main body (101) between a first position where the liquid blocking element (104) prevents the tobacco liquid in the liquid chamber (108) from flowing into the liquid passage (107), and a second position where the notch (105) is in alignment with the liquid passage (107), so that the tobacco liquid flows to the atomizing component (106) via the liquid passage (107).
