Electronic Atomizer Power Staging for Burnt Smell Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomization devices face issues with the viscosity and fluidity of liquid substrates, leading to overheating and a burnt smell during heating and atomization, which negatively impacts the user's inhalation experience.
Innovation Solution
The electronic atomization device employs a control method that adjusts the power supply to the heating element in two stages: a first power stage to increase the temperature without volatilizing the liquid substrate, and a second power stage to achieve atomization, thereby improving fluidity and preventing overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid substrate is heated at high power to achieve rapid atomization, then the atomization efficiency is improved, but the liquid substrate becomes overheated and burnt, causing a burnt smell
Solution Approach 1:
The patent applies preliminary action by pre-heating the heating element to a preset temperature before actual atomization. This preliminary heating phase prepares the heating element in advance, ensuring it reaches the optimal temperature for atomization without causing burnt smell during the atomization process itself. The controller specifically controls the heating element to heat to the preset temperature before the liquid substrate is fully atomized.
Solution Approach 2:
The patent implements periodic action through two distinct power stages: a first power stage for pre-heating and a second power stage for atomization. The controller switches between these stages periodically, first applying lower power to heat the element to preset temperature, then switching to higher power for rapid atomization. This periodic power adjustment prevents continuous overheating while maintaining efficient atomization.
2Speed
If the heating element is heated rapidly to atomization temperature, then the atomization speed is improved, but the liquid substrate viscosity remains high, causing poor fluidity and uneven heating
Solution Approach 1:
The patent applies preliminary action by first heating the heating element to a preset temperature before initiating rapid atomization. This preliminary heating phase allows the liquid substrate to gradually reduce its viscosity and improve fluidity, ensuring smooth flow and uniform heating distribution before the high-speed atomization phase begins.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting the power supply parameters in two stages. The controller first sets the power to a first level for pre-heating, allowing the temperature and viscosity parameters of the liquid substrate to change favorably. Then it switches to a second power level for rapid atomization, optimizing both speed and fluidity through controlled parameter transitions.
3Ease of operation
If preheating is performed before atomization, then the liquid substrate fluidity is improved, but the user needs to wait longer before use
Solution Approach 1:
The patent implements periodic action through two distinct power stages: a first power stage for pre-heating and a second power stage for atomization. The controller switches between these stages periodically, first applying lower power to heat the element to preset temperature, then switching to higher power for rapid atomization. This periodic power adjustment prevents continuous overheating while maintaining efficient atomization.

AI summary
An electronic atomization device and a control method are provided. The electronic atomization device includes a heating element and a battery core. The method includes: controlling the battery core to supply electric power to the heating element at a first power when an inhalation starting signal is obtained, so that a temperature of the heating element increases from an initial temperature to a preset temperature, where the preset temperature does not enable at least one component of the liquid substrate to volatilize; controlling the battery core to supply the electric power to the heating element at a second power, so that the temperature of the heating element increases from the preset temperature to an atomization temperature, where the second power is greater than the first power.
