Thermosensitive Liquid Intake Control in Atomizing Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing devices face a trade-off between liquid conductivity and leakage prevention due to micropores in the porous medium, where small pores cause slow liquid supply and blockage, while large pores lead to leakage.
Innovation Solution
An atomizing device with a thermosensitive metal sheet as a liquid intake adjusting member that deforms in response to temperature changes of the heating atomizing assembly, adjusting the liquid intake amount to ensure smooth supply during operation and prevent leakage during non-use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If small micropores are used in the porous medium, then oil locking performance is improved, but liquid supply becomes poor and micropores block easily
Solution Approach 1:
The liquid supply path is segmented into two distinct channels: a porous medium channel for oil locking and a non-porous liquid guide channel for smooth liquid supply. This segmentation allows each channel to be optimized for its specific function without compromise.
Solution Approach 2:
A liquid guide member acts as an intermediary component between the liquid storage bin and the heating atomizing assembly. It provides a dedicated non-porous pathway that mediates between the conflicting requirements of the porous medium, ensuring smooth liquid flow while maintaining oil locking performance.
2Productivity
If large micropores are used in the porous medium, then liquid conducting performance is improved, but oil leakage occurs during use and transportation
Solution Approach 1:
The liquid supply system is divided into separate functional zones: the porous medium maintains oil locking while the non-porous liquid guide channel handles high-rate liquid conduction, eliminating the need for large micropores that would cause leakage.
Solution Approach 2:
Different regions of the liquid guide system have different pore structures optimized for their local functions: the porous medium region provides oil locking with small pores, while the liquid guide channel region provides smooth conduction with non-porous or large-pore structure.
3Reliability
If a porous liquid guide member is used as the only channel, then oil locking is achieved through negative pressure, but liquid supply becomes slow and micropores block
Solution Approach 1:
The single porous channel is segmented into a dual-channel system where the porous medium handles oil locking and the additional non-porous liquid guide channel handles liquid supply, reducing blockage risk and improving flow rate.

AI summary
An atomizing device and an aerosol generating device. The atomizing device comprises an oil storage bin, an atomizing mounting assembly, a heating atomizing assembly and a liquid intake adjusting member. The oil storage bin is internally provided with an air guide channel and an oil storage cavity used for storing an atomizable liquid. The heating atomizing assembly is mounted in the atomizing mounting assembly and is accommodated in the oil storage bin. A liquid guide channel is arranged between the heating atomizing assembly and the oil storage cavity. The liquid intake adjusting member is provided at a position in the liquid guide channel that is close to the heating atomizing assembly, is a thermosensitive metal sheet, and deforms upon sensing a change in the temperature of the heating atomizing assembly, so as to automatically adjust the magnitude of a liquid intake amount.
