Atomizing Device With Silver-Coated Wire For E-Cigarette
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing devices in electronic cigarettes suffer from high contact resistance and energy loss due to the entire heating coil generating heat, leading to scalding and abnormal taste, as well as energy surplus in non-winding sections of the coil, which affects the atomizing effect.
Innovation Solution
The atomizing device employs a silver-coated bare electrical wire connected to the ends of the heating coil, avoiding contact with the heating coil support to prevent scalding and reducing contact resistance, along with a nichrome heating coil of specific diameter and a glass fiber core with optimal winding, to minimize energy loss and maintain taste quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the entire heating coil generates heat, then the heating effect is enhanced, but the heating coil support gets scalded causing abnormal taste
Solution Approach 1:
The heating coil is divided into a working section (wound around the glass fiber core) and a non-working section (extending beyond the core). Only the working section contacts the glass fiber core and generates heat for atomization, while the non-working section does not contact the support, preventing scalding. This segmentation resolves the contradiction by localizing the heat generation to only where needed.
2Loss of energy
If the heating coil does not wind around the glass fiber core, then energy is saved, but contact resistance increases at the electrical connections
Solution Approach 1:
Silver-coated bare electrical wires are introduced as intermediaries to connect the heating coil ends to the heating coil support. The silver coating provides excellent electrical conductivity, reducing contact resistance at the connection points. This allows the heating coil to extend beyond the glass fiber core (reducing energy loss in non-working sections) while maintaining reliable electrical connections.
3Strength
If the heating coil contacts the heating coil support, then structural support is provided, but contact resistance and energy loss increase
Solution Approach 1:
The silver-coated bare electrical wires serve as intermediaries between the heating coil and the heating coil support. These wires provide both mechanical support (holding the heating coil in position) and excellent electrical conductivity (minimizing contact resistance). The silver coating specifically addresses the energy loss issue by reducing contact resistance at the connection points.
Solution Approach 2:
The use of silver-coated wires combines the mechanical properties of the bare wire (structural support) with the electrical properties of the silver coating (low contact resistance). This composite structure resolves the contradiction between needing structural support and minimizing energy loss through contact resistance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces contact resistance and energy loss, preventing scalding and maintaining the taste quality of electronic cigarettes by using silver-coated wires and optimizing the heating coil and glass fiber core configuration, resulting in efficient atomization and improved user experience.
Implementation Method 1
Two ends of the heating coil are electrically connected to a power source. In application, a tobacco solution absorbed in the glass fiber core is atomized by the heating coil
Implementation Method 2
Each of two ends 21 of the heating coil 2 is respectively connected to a silver coated bare electrical wire 22... the silver coated bare electrical wires would generate little heat when electric current flows through the bare electrical wires, thus the heating coil support 3 would not be scalded
