Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly precision and consistency of atomizing cores in atomizers affect the atomization effect and stability due to the influence of air flow volume and flow rate, which is compromised by imperfect assembly of the atomization chamber and air inlet/outlet defined by the atomizing core and other parts.
Innovation Solution
An atomizing core with a liquid transfer unit made of porous material and an air flow chamber, where the heating unit is disposed within the air flow chamber, allowing the air flow volume, flow rate, and path to be determined by the structure of the liquid transfer unit, independent of other parts, with an air inlet and outlet communicated with the chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If liquid is supplied to the atomization core at a location where the liquid flow rate is small, then liquid can be supplied, but the atomization performance deteriorates due to insufficient liquid supply
Solution Approach 1:
The patent introduces a liquid supply passage that extends upstream toward the liquid supply source, allowing liquid to be supplied earlier in the flow path where liquid velocity is lower. This preliminary action ensures adequate liquid supply quantity reaches the atomization region, resolving the contradiction between sufficient liquid supply and maintaining atomization performance.
2Reliability
If liquid is supplied at a location with high liquid flow rate, then atomization performance improves, but liquid supply becomes difficult due to high velocity
Solution Approach 1:
The liquid supply passage is positioned upstream where liquid velocity is lower, enabling easy liquid supply introduction before the liquid accelerates through the nozzle. This allows liquid to be supplied at a favorable location with lower flow rate, while still achieving good atomization performance through the designed passage geometry and positioning.
3Ease of manufacture
If the atomization core structure is simplified, then manufacturing becomes easier, but liquid supply control and atomization performance deteriorate
Solution Approach 1:
The atomization core is designed with a multi-functional structure where the liquid supply passage serves multiple purposes: it guides liquid from the source, controls liquid flow distribution, and integrates with the nozzle structure. This universal design achieves both manufacturing simplicity and reliable atomization performance through a unified component rather than separate assemblies.
Solution Approach 2:
The atomization core is divided into functionally distinct regions: a liquid supply passage region for liquid introduction and a nozzle region for atomization. This segmentation allows each region to be optimized for its specific function while maintaining overall structural simplicity and manufacturability.
4Length of moving object
If the nozzle is positioned close to the liquid supply location, then structure is compact, but liquid supply quantity becomes insufficient
Solution Approach 1:
The liquid supply passage extends in the longitudinal direction toward the liquid supply source, utilizing the length dimension to accommodate sufficient liquid supply path. This dimensional arrangement allows the nozzle to remain compact while the supply passage reaches upstream to gather adequate liquid quantity, resolving the contradiction between compactness and liquid supply quantity.

AI summary
The present invention provides an atomizing core which includes a heating unit, and a liquid transfer unit made of a porous material and configured for absorbing and transferring liquid. The liquid transfer unit includes an air guide part, and a base connected to and surrounding the air guide part. A gap between the air guide part and the base forms an air flow chamber. The liquid transfer unit is provided with an air inlet communicated with the air flow chamber, an air outlet communicated with the air flow chamber, and a liquid inlet part for contacting with the liquid. The heating unit includes a heating part which generates heat when energized, and electrical connection parts for transmitting currents to the heating part. The heating part is disposed on an inner wall of the air flow chamber and in contact with the liquid transfer unit. Due to the fact that the air flow chamber of the atomizing core is disposed in the liquid transfer unit made of a porous material and the heating part of the heating unit are disposed in the air flow chamber, the volume, flow rate and path of the air flow are determined mainly by the structure of the liquid transfer unit and not affected by other parts and the assembly relation of parts, so the consistency of the atomization effect is guaranteed.
