Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic electronic cigarette atomizing cores face issues with slow atomization startup, uncontrollable tobacco tar guide speed, tobacco tar submersion, and excessive heat transfer leading to burning hot atomizer outer pipes, along with difficulties in replacing the atomizing core.
Innovation Solution
The ultrasonic electronic cigarette atomizing core features a cup-shaped tobacco tar guide cotton with a central through hole, an atomizing core sleeve with inner and outer layers to control tightness, and a downward protruding circular arc surface for efficient atomization, along with a vent groove system to reduce friction and heat transfer, and an elastic bracket to maintain contact with the atomizing piece, while the atomizer outer pipe is designed for reduced heat transfer and easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If tobacco tar guide cotton is placed flatwise with large contact area on the atomizing piece, then the contact area is increased, but the atomization startup time becomes slow (tens of seconds)
Solution Approach 1:
The tobacco tar guide cotton is segmented into multiple strips rather than a single large piece. This segmentation reduces the total contact area while maintaining effective tobacco tar guidance, enabling faster atomization startup without sacrificing functionality.
2Ease of operation
If the silica gel seat axially extrudes the tobacco tar guide cotton to control tightness, then the tobacco tar guide speed is controlled, but the atomizing piece is excessively extruded affecting oscillation effect
Solution Approach 1:
The tobacco tar guide cotton is divided into multiple independent strips that can be individually compressed. This allows for more uniform and controlled compression force distribution, preventing excessive extrusion of the atomizing piece while maintaining effective tobacco tar guidance speed control.
3Device complexity
If the tobacco tar inlet hole is vertically formed close to the atomizing piece, then the structure is simplified, but the tobacco tar guide speed becomes uncontrollable and submersion occurs
Solution Approach 1:
The tobacco tar guide path is segmented into multiple strips with controlled spacing and contact areas. This segmentation provides natural flow resistance control, preventing tobacco tar submersion while maintaining a relatively simple overall structure without requiring complex inlet hole designs.
4Device complexity
If the atomizing core sleeve is single-layer pipe wall structure, then the structure is simple, but heat transfers easily to the atomizer outer pipe causing burning hot phenomenon
Solution Approach 1:
The atomizing core sleeve adopts a nested multi-layer pipe wall structure where inner and outer sleeves are positioned concentrically. This nested configuration creates thermal insulation layers that reduce heat transfer to the atomizer outer pipe, preventing burning hot phenomenon while maintaining structural compactness.
