Solution Overview

Problem

Conventional electronic cigarette atomizers experience e-cigarette liquid splashing and leakage due to insufficient atomization, leading to pollution and increased cleaning workload, which negatively impacts user experience.

Innovation Solution

An atomizer design featuring a liquid storage groove with a protrusion body and convex curved surface, where e-cigarette liquid splashes flow into the groove, preventing leakage through ventilation holes, and an integrated liquid guiding member ensures efficient liquid usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the atomizer uses a conventional structure with ventilation holes in the bottom seat, then air can flow into the atomizing chamber for aerosol formation, but e-cigarette liquid splashes and leaks through the ventilation holes causing pollution and cleaning issues

Engineering Contradiction:
Improveleak-proof performanceVSAvoidliquid leakage and pollution
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The bottom seat is divided into a leakage prevention groove area and a ventilation hole area. The leakage prevention groove is segmented into a first groove (for collecting splashed liquid) and a second groove (for further containment). This segmentation allows the structure to simultaneously provide liquid containment and ventilation functions without liquid leaking through the ventilation holes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The leakage prevention groove acts as an intermediary structure between the atomizing chamber and the ventilation holes. It intercepts and collects splashed e-cigarette liquid before the liquid can reach the ventilation holes, thereby preventing leakage while maintaining normal air flow through the ventilation holes.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the atomizer allows free flow of air through ventilation holes, then atomization efficiency is improved, but splashed liquid can escape through the same holes

Engineering Contradiction:
Improveatomization efficiencyVSAvoidliquid escape through ventilation holes
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

Different areas of the bottom seat are given different functions: the ventilation holes provide air flow pathways for atomization efficiency, while the leakage prevention groove provides liquid containment. This local differentiation allows each area to optimize its specific function without interfering with the other.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If the atomizing chamber allows liquid to splash freely, then liquid distribution may be improved, but liquid aggregates and leaks through ventilation holes increasing cleaning workload

Engineering Contradiction:
Improveliquid distributionVSAvoidcleaning workload
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The leakage prevention groove, which initially seems to be an additional complex structure, actually simplifies the overall system by eliminating the need for external cleaning mechanisms. It passively collects and contains splashed liquid, converting the harmful effect of splashing into a beneficial self-cleaning function that reduces user maintenance workload.

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

AI summary

An atomizer (10) and an electronic cigarette (100). The atomizer (10) comprises an atomizing head (14) and a base assembly (13) disposed at one end of the atomizing head (14). The atomizing head (14) is provided with an atomizing chamber (145). The base assembly (13) comprises a base (131). A liquid reservoir (1311) is disposed on the base (131), and the liquid reservoir (1311) is communicated with the atomizing chamber (145). A protrusion (1312) is provided in the liquid reservoir (1311). At least one air vent (1314) is formed on the protrusion (1312). During e-liquid splashing, splashing liquid falls onto the protrusion (1312), and then can flow into the liquid reservoir (1311) along the protrusion (1312). The atomizer (10) avoids leakage of e-liquid from the air vent (1314), has a simple structure and outstanding effects, reduces a user's cleaning work, and improves the user experience.
