Solution Overview

Problem

Existing atomizers suffer from poor reliability in resisting liquid leakage during the atomizing process due to condensate accumulation in the main airway, leading to inefficiencies and potential liquid leakage.

Innovation Solution

The atomizer incorporates a heating top cover with an airway convex fillet and a liquid return groove that guides condensate back to the heating body for secondary atomization, preventing accumulation and leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a structure for guiding condensate to heating top cover is provided, then liquid leakage is reduced, but reliability against liquid leakage during inhaling remains poor

Engineering Contradiction:
Improvereliability against liquid leakageVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of guiding condensate away from the airway, the patent inverts the approach by creating a convex fillet structure that actively directs condensate back toward the heating element through surface tension and gravity, reversing the traditional drainage concept

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent employs a convex fillet with specific curvature radius (R1≥0.5mm, R2≥1mm) to create a curved surface that利用表面张力 and gravity to guide condensate flow, using geometric curvature to achieve reliable liquid management

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Device complexity

If condensate is allowed to accumulate in main airway, then device structure remains simple, but liquid leakage occurs during atomizing

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful effect of condensate accumulation into a beneficial process by designing the convex fillet to guide condensed liquid back to the heating element for re-vaporization, turning potential leakage into a secondary atomization opportunity that improves efficiency

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

The present invention relates to a atomizer and an electronic atomizing device. The atomizer includes a main body and a heating top cover and a heating body that are connected to each other and that are provided in the main body. The main body includes a main airway, the heating top cover includes an airway corner, and a liquid return groove extending from the heating top cover to the heating body is provided at the airway corner. The liquid return groove is used for liquid accumulated at the airway corner to return to the heating body. The electronic atomizing device is electrically connected to the heating body of the atomizer. The liquid return groove is provided at the airway corner, to guide liquid detained at the airway corner to a heating element for secondary atomizing of the liquid, so that the occurrence of a case in which liquid is accumulated and detained is effectively reduced, thereby reducing the case in which the liquid enters the main airway and leaks in a atomizing process. The foregoing arrangement manner features low costs and a simple structure, and enables the atomizer and the electronic atomizing device to have better resistance against liquid leakage during inhaling.
