Innovation Solution
A heating core assembly with N pins dividing the core into N-1 heating parts, controlled by a heating control board to operate in turn, in parallel, or in series, along with an atomization device and power supply configuration that includes an oil storage system with silica gel members and a ceramic ring to manage oil flow and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the heating core operates for a long time, then the device can provide continuous atomization service, but carbon deposits accumulate on the heating core reducing service life and atomization efficiency
Solution Approach 1:
The heating core is divided into N-1 independent heating parts through N pins, allowing each segment to be controlled independently. This segmentation enables rotational switching between multiple heating segments, preventing carbon deposit accumulation on any single segment and extending the overall service life while maintaining atomization efficiency.
2Adaptability or versatility
If the heating core has a fixed resistance, then the device structure is simple, but the mist output amount cannot be adjusted to meet personalized user needs
Solution Approach 1:
The heating control board dynamically switches between series and parallel connections of the N pins, changing the total resistance of the heating core. This dynamic resistance adjustment allows control over the heating power and mist output amount, providing personalized user experience without requiring multiple fixed-resistance heating cores.
3Reliability
If the heating core is divided into multiple heating parts with N pins, then the mist output can be adjusted and carbon deposits are reduced, but the device complexity increases
Solution Approach 1:
The N pins serve multiple functions: they divide the heating core into segments, act as switching points for rotational control, and enable series/parallel resistance adjustment. This multi-functionality reduces the need for separate components and minimizes overall device complexity while achieving the desired reliability improvements.

AI summary
A heating core assembly includes a heating core and a heating control board. The heating core has N pins arranged at intervals to divide the heating core into N−1 heating parts, where Nis an integer and N≥3. The heating control board is electrically connected to each of the N pins to control respective voltages at the N pins, so that the N−1 heating parts work in one of a first mode in which at least two of the N−1 heating parts work in turn, a second mode in which at least two of the N−1 heating parts are electrically connected in parallel, and a third mode in which at least two of the N−1 heating parts are electrically connected in series.
