Solution Overview
Problem
Existing electronic heating atomization devices face issues with air entering the liquid storage chamber through gaps, impeding liquid conduction and affecting supply due to higher external pressure, which can lead to burning of the heating member.
Innovation Solution
An electronic heating atomization assembly with a base body featuring liquid inlet capillary holes and an air exchange channel, designed to control air intake path by utilizing surface tension and micro-pores, ensuring liquid supply is not obstructed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the liquid storage chamber is connected to the exterior through gaps, then air can enter the chamber to balance pressure, but liquid conduction is impeded and heating member burning occurs
Solution Approach 1:
The patent separates the air intake function from the liquid supply function by providing distinct channels: air exchange channels for pressure balance and liquid inlet capillary holes for liquid supply. This segmentation prevents air from entering through the liquid supply path, eliminating the risk of liquid conduction impairment and heating member burning while maintaining pressure stability.
Solution Approach 2:
The patent introduces an intermediary structure (air exchange channel) that mediates the pressure balance function separately from the liquid supply system. This intermediary channel allows air to enter the liquid storage chamber without interfering with the liquid conduction path, thus maintaining both pressure stability and liquid supply reliability.
2Stability of the object's composition
If air enters the liquid storage chamber through gaps, then pressure is balanced, but the liquid guide channels are occupied and liquid supply is affected
Solution Approach 1:
The patent divides the pressure balance and liquid supply functions into separate channels: air exchange channels for pressure regulation and liquid inlet capillary holes for liquid supply. This ensures that air enters through dedicated air channels without occupying liquid guide channels, maintaining full liquid supply efficiency while achieving pressure balance.
Solution Approach 2:
The air exchange channel acts as an intermediary pathway that enables pressure balance without interfering with the liquid supply system. By providing this separate mediation channel, the patent ensures that air intake does not block or occupy liquid guide channels, preserving liquid supply efficiency.
3Quantity of substance
If the liquid inlet opening is large, then liquid supply is sufficient, but air can easily enter and obstruct liquid conduction
Solution Approach 1:
The patent segments the liquid inlet into multiple capillary holes instead of a single large opening. This segmentation maintains sufficient total liquid supply quantity while each small capillary hole resists air entry due to surface tension effects, thereby preserving liquid conduction reliability.
Solution Approach 2:
The patent changes the parameter of the liquid inlet from a large single opening to multiple small capillary holes. This parameter change exploits capillary action and surface tension to prevent air entry while maintaining adequate liquid supply quantity, thus ensuring liquid conduction reliability.

Function Achieved in This Case
The design effectively prevents air from entering the liquid supply channel, maintaining consistent liquid flow and preventing heating member burn by directing air through a separate air exchange channel, thus ensuring reliable operation.
