Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic high-frequency atomizers in electronic cigarettes face issues with tobacco tar supply control, leading to inefficient atomization, cotton burning, and health hazards due to uncontrolled tar guide cotton, resulting in suboptimal smoke quality and heat efficiency.
Innovation Solution
A combined ultrasonic atomizer using a micropore atomization piece for initial oscillation and a high-frequency atomization piece for secondary oscillation, with a silica gel base and controlled air passages, eliminates direct contact with tar guide cotton, ensuring precise tobacco tar supply and improved atomization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tobacco tar guide cotton is used to guide tobacco tar, then the atomization process can proceed, but the supply speed of tobacco tar is hard to control, resulting in either soaking of atomization pieces or insufficient supply
Solution Approach 1:
The patent removes the tobacco tar guide cotton from the system entirely. Instead of using cotton to guide and supply tobacco tar, the invention uses ultrasonic vibration of the atomization piece itself to directly atomize the tobacco tar, eliminating the uncontrolled supply mechanism and achieving precise control through ultrasonic frequency modulation.
Solution Approach 2:
The patent replaces the mechanical cotton-based supply system with an ultrasonic vibration-based atomization system. The ultrasonic atomization piece vibrates at high frequency to atomize tobacco tar directly, substituting the passive mechanical guidance of cotton with active ultrasonic atomization that provides controllable supply speed.
2Quantity of substance
If tobacco tar guide cotton is used, then atomization can occur, but particles become larger and smoke is weakened when penetrating through the cotton
Solution Approach 1:
The patent extracts and removes the tobacco tar guide cotton that causes particle enlargement. By eliminating the cotton layer that smoke must penetrate, the system directly atomizes tobacco tar into fine particles without the intermediate step of passing through cotton fibers, thereby maintaining small particle size and strong smoke output.
3Device complexity
If tobacco tar guide cotton is used, then atomization structure is simple, but cotton burning phenomenon occurs with insufficient supply, producing burnt flavor and harmful substances
Solution Approach 1:
The patent removes the combustible tobacco tar guide cotton from the system. Without cotton present in the atomization area, there is no material to burn when tobacco tar supply is insufficient, thereby eliminating burnt flavor and harmful combustion byproducts while maintaining a relatively simple atomizer structure.
Solution Approach 2:
The patent eliminates the harmful combustion effect by removing the cotton material that would otherwise burn. The ultrasonic atomization piece itself does not burn because it is designed to vibrate and atomize tobacco tar without reaching combustion temperatures, converting the potential harm of cotton burning into a benefit of clean, controlled atomization.
4Device complexity
If tobacco tar guide cotton is used, then initial atomization structure is simple, but heat efficiency is low and atomization start speed is slow due to heat absorption by cotton
Solution Approach 1:
The patent removes the tobacco tar guide cotton that absorbs heat during the atomization process. Without cotton present, heat energy is not wasted on heating and potentially burning the cotton material, thereby improving heat efficiency and reducing energy loss while maintaining a simple atomizer structure.
