Solution Overview

Problem

Existing atomization devices do not effectively protect breath detectors from damage caused by oil droplets that can condense on the detector's surface due to reverse mist flow in the gas passage.

Innovation Solution

The atomization device includes a housing with a suction part, a mist outlet pipeline, an atomization channel, and a breath detector. A first gas hole is provided on the suction part, and the atomization channel, oil storage tank, and mist outlet pipeline are isolated from the breath detector's gas passage, preventing oil mist from reaching the breath detector.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the gas passage of breath detector is directly connected with the atomization channel or mist outlet pipeline, then the breath detector can detect the gas flow in the atomization channel, but the mist in the atomization channel or mist outlet pipeline is likely to flow reversely along the gas passage for the breath detector and contact the breath detector to form oil droplets that may cause damage to the breath detector

Engineering Contradiction:

Improvegas flow detectionVSAvoidbreath detector protection

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The gas passage is divided into two separate systems: one for the atomization channel leading to the mist outlet, and another for the breath detector leading to the suction port. This segmentation allows the breath detector to detect gas flow through the suction port without being exposed to mist from the atomization channel, thus preventing oil droplet accumulation while maintaining detection functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The suction port serves as an intermediary component that allows the breath detector to indirectly detect gas flow from the atomization channel. By routing the detector's gas passage through the suction port rather than directly connecting it to the atomization channel, the system enables detection while preventing direct exposure to harmful mist.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the atomization core always operates to heat the oil, then the atomization device can be ready for use, but the atomized oil cannot flow out of the atomization device along with the gas flow and will accumulate in the atomization device causing leakage

Engineering Contradiction:

Improvereadiness for useVSAvoidoil accumulation prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The breath detector provides real-time feedback on whether the user is suctioning, which controls the atomization core operation. When suction is detected, the atomization core heats the oil and gas flow carries the atomized oil to the user. When no suction is detected, the atomization core stops heating, preventing oil accumulation. This feedback mechanism ensures the device is ready for use while preventing leakage.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The atomization core's operation is made dynamic rather than static. It automatically activates when suction is detected and deactivates when suction stops, adapting its operation to real-time user needs. This dynamic control prevents oil accumulation while maintaining readiness for immediate use.

Inventive Principle:

Principle #15Dynamics
