Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic electronic cigarette atomizers experience delayed smoke production at startup, leading to insufficient initial smoke intake and discomfort due to excessive heating of the atomizer shell.
Innovation Solution
Incorporating a heating body in the atomizer shell to aid in auxiliary heating of the atomization piece, along with a liquid guide structure and airflow passages to enhance smoke production and reduce shell temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only ultrasonic vibration heating is used in the atomization piece, then the structure is simple, but the atomization piece cannot immediately atomize tobacco tar to produce smoke at startup
Solution Approach 1:
The heating body pre-heats the tobacco tar in the liquid guide structure before the atomization piece reaches working temperature, so that when ultrasonic vibration starts, the tobacco tar is already in a state ready for immediate atomization, eliminating the delay period
Solution Approach 2:
The heating body acts as an intermediary heating device that bridges the gap between room temperature and atomization temperature, providing auxiliary heating to the tobacco tar before it reaches the atomization piece surface
2Temperature
If the atomization piece generates high temperature for atomization, then atomization effect is improved, but the heat is transferred to the atomizer shell making it burning hot
Solution Approach 1:
The heating system is segmented into two independent components: the atomization piece for ultrasonic atomization and the separate heating body for pre-heating tobacco tar. This segmentation allows the atomization piece to maintain high temperature for effective atomization while the heating body handles the heating function, preventing excessive heat transfer to the atomizer shell
Solution Approach 2:
The liquid guide structure serves as a thermal intermediary, allowing the heating body to heat the tobacco tar before it reaches the atomization piece, thereby reducing the overall heat load on the atomizer shell while ensuring sufficient temperature for atomization
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

AI summary
Disclosed is an ultrasonic electronic cigarette atomizer. An atomizer shell, an atomization piece and a liquid guide structure are arranged in the atomizer. The liquid guide structure communicates with a liquid storage cavity in the atomizer shell. A heating body is further arranged in the atomizer shell. Both of the atomization piece and the heating body are in contact with the liquid guide structure, and both of the heating body and an atomization surface of the atomization piece communicate with an airflow passage, and a positive electrode and a negative electrode of the heating body are respectively connected with one end and the other end of a power supply. The heating body can not only quickly heat the tobacco tar to approach to its atomization temperature, but also can transfer a part of heat to the atomization piece, so that the atomization piece atomizes the tobacco tar quickly, shortening the atomization time.
