Top-Entry Atomizer Assembly for E-Cigarette Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarettes are prone to liquid leakage due to the liquid leaking from the atomizing assembly, which affects user experience and device functionality, and existing leakproof structures are complex and unreliable.
Innovation Solution
An atomizer design featuring an adjustment assembly with a rotatable adjustment member that controls the exposure of liquid and air inlet ports, allowing for simplified structure and top-entry aerosol generation, eliminating the need for a detachable connection and preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a leakproof structure is added to prevent liquid leakage, then liquid leakage is reduced, but device complexity increases and reliability decreases
Solution Approach 1:
The patent extracts the liquid inlet port from the traditional side-entry position and relocates it to the top entry position. This extraction of the problematic liquid inlet function from its original location eliminates the need for complex leakproof structures while preventing liquid leakage through the simplified top-entry design
2Ease of manufacture
If a detachable connection is used for atomizing assembly, then ease of assembly is improved, but liquid leakage risk increases
Solution Approach 1:
The patent merges the liquid inlet function with the air inlet function at the top entry position, combining what were previously separate functions into a single integrated top-entry structure. This merging eliminates the need for detachable connections while preventing liquid leakage through the unified design
3Productivity
If liquid inlet port is exposed at side entry, then liquid flow is improved, but liquid leakage increases
Solution Approach 1:
The patent inverts the traditional side-entry liquid inlet design by implementing a top-entry liquid inlet. This inversion changes the direction and position of liquid flow entry, allowing liquid to flow horizontally across the top surface rather than vertically from the side, which prevents liquid from leaking out while maintaining adequate flow

AI summary
An atomizer includes an atomizing assembly and an adjustment assembly thereon. The atomizing assembly includes an accommodation cavity and the adjustment assembly includes a substrate and an adjustment member rotatably disposed on the substrate. A liquid inlet port is defined in the substrate and in liquid communication with the accommodation cavity. The adjustment member adjusts a size of the liquid inlet port exposed during rotation of the adjustment member. Another atomizer includes an atomizing assembly and an adjustment assembly disposed on the upper end of the atomizing assembly. The atomizing assembly includes an atomizing cavity and an air passage. The adjustment assembly comprises an air inlet port communicating with outside. The air passage has one end communicating with a top of the atomizing cavity and another end communicating with the air inlet port. The atomizer is simple in structure and liquid leakage is prevented. An aerosol generating device including either one of the above atomizers is also provided.
