Atomizing Head Heater Pin Fracture Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic cigarettes, the heater pin is prone to fracture, deformation, and detachment during the welding process, leading to low production efficiency, high costs, short service life, and reduced heat efficiency due to increased electrical resistance at the welded portion.
Innovation Solution
The atomizing head design eliminates the need for welding by directly connecting the heater to the electrode, using a bracket with a second electrode and a heater received within the atomizing chamber, where the heater's ends resist the electrodes, and includes insulating members and absorbing materials to enhance stability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heater pin is welded to the electrode, then electrical conduction is realized, but the heater pin is prone to fracture, deformation, and detachment
Solution Approach 1:
The patent removes the heater pin from the system entirely, replacing it with a heater block that is directly embedded in the atomizing chamber. This extraction eliminates the welded connection between heater pin and electrode, thereby removing the source of fracture, deformation, and detachment problems while maintaining electrical conduction through direct contact between the heater block and electrode.
2Ease of manufacture
If the heater pin is welded to the electrode, then electrical conduction is realized, but production efficiency is low and cost is high
Solution Approach 1:
The patent merges the heater pin function into the heater block structure, eliminating the need for separate welding operations. The heater block is directly installed in the atomizing chamber and makes direct contact with the electrode, combining what were previously separate components (heater pin, welding joint, electrode) into a simplified assembly process that improves both manufacturing ease and production efficiency.
3Duration of action of stationary object
If the heater pin is welded to the electrode, then electrical conduction is realized, but the service life of the heater is short
Solution Approach 1:
By removing the heater pin and its welded connections, the patent eliminates the failure points associated with welding joints. The heater block directly contacts the electrode without requiring welding, thereby extending the service life and improving the reliability of the heating system.
4Loss of energy
If the heater pin is welded to the electrode, then electrical conduction is realized, but the electrical resistance of the welded portion is greater, reducing heat efficiency
Solution Approach 1:
The patent removes the welded portion from the system by eliminating the heater pin. The direct contact between the heater block and electrode creates a lower resistance electrical connection compared to a welded joint, thereby reducing energy loss and improving heat efficiency.
