Detachable Atomizing Head for Electronic Cigarettes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional refillable atomizers have a fixed atomizing head that is not removable, leading to high costs and environmental impact when it breaks, as the entire device becomes unusable.
Innovation Solution
A detachable atomizing head with a main body, air inlet, exit pipe, connecting electrodes, liquid conducting element, and heating element, allowing for the absorption and heating of tobacco liquid to form aerosol, with a ceramic liquid conducting element and sealing elements to prevent liquid leakage and facilitate easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the atomizing head is fixedly arranged in the atomizer, then the structure is simple and reliable, but the cost increases and environmental friendliness decreases when the atomizing head breaks
Solution Approach 1:
The atomizer is divided into separable components: a reusable body and a replaceable atomizing head. The atomizing head can be detached and replaced independently when worn or broken, allowing the main body to continue being used. This segmentation enables partial replacement rather than complete disposal, reducing waste while maintaining reliability.
2Device complexity
If the atomizing head is fixedly arranged in the atomizer, then the structure is simple, but the cost of smoking becomes high when the atomizing head breaks
Solution Approach 1:
The atomizer system is segmented into a permanent body and a consumable atomizing head. The body housing, liquid reservoir, and control electronics are designed to be reused, while only the atomizing head (containing the heating element and wick) needs periodic replacement. This reduces overall cost by allowing users to invest once in the durable body and periodically replace cheaper heads.
Solution Approach 2:
The atomizing head is designed as a disposable or replaceable component with a limited service life. It incorporates the heating element and liquid-conducting materials that degrade with use. By making this specific component replaceable and relatively inexpensive compared to the entire atomizer, the system reduces long-term costs while maintaining performance.
3Device complexity
If the atomizing head is fixedly arranged in the atomizer, then the structure is simple, but the environmental friendliness decreases when the atomizing head breaks
Solution Approach 1:
The atomizer is segmented into reusable and disposable portions. The main body is designed for long-term use and can be refilled and maintained, while only the atomizing head requires replacement. This reduces environmental impact by minimizing the frequency and volume of waste generated, as users discard only small head components rather than entire devices.
Solution Approach 2:
The design enables selective discarding of the atomizing head while recovering and retaining the main body for continued use. The reusable body can be cleaned, maintained, and reused multiple times with different atomizing heads, thereby reducing overall waste generation and environmental footprint.

AI summary
An exemplary atomizing head includes a main body, an air inlet, an exit pipe, two connecting electrode, a liquid conducting element, and a heating element. The main body defines an atomizing chamber and a through hole. The through hole conumunicates with the atomizing chamber such that tobacco liquid can flow into the atomizing chamber. The liquid conducting element is configured for absorbing tobacco liquid. The liquid conducting element defines at least one air passage. The heating element is in contact with the liquid conducting element. The heating element is configured for heating the tobacco liquid to form aerosol. The aerosol is expelled via the at least one air passage. Two opposite ends of the heating element are connected to the two connecting electrodes.
