Solution Overview

Problem

Existing inhalation devices suffer from inconsistent mist output and evaporation of atomization material, particularly after prolonged non-use, leading to deviations in mist amount and potential blockages in microfluidic channels.

Innovation Solution

An inhalation device with a movable cover body and blocking member that can be attached to the mist outlet to prevent evaporation and block the outlet when not in use, featuring a housing, atomization structure, and a blocking member that can be detachably connected or magnetically attached to the cover body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the mist outlet remains open during non-use periods, then the device is ready for immediate use, but the atomization material evaporates causing inconsistent mist output

Engineering Contradiction:

Improvereadiness for useVSAvoidmist output consistency

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The blocking member is pre-positioned on the cover body and automatically engages with the mist outlet when the cover body is in the closed position, preventing evaporation during non-use periods without requiring manual intervention

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The blocking member acts as an intermediary element between the cover body and the mist outlet, providing a mechanical barrier that prevents atomization material from evaporating through the mist outlet during storage

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a blocking member is added to the cover body to block the mist outlet, then evaporation is prevented and mist output consistency is improved, but the device structure becomes more complex

Engineering Contradiction:

Improvemist output consistencyVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The blocking member is integrated with the cover body through magnetic connection, combining the covering function and blocking function into a single coordinated mechanism rather than separate components

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The magnetic connection between the blocking member and cover body replaces traditional mechanical fastening methods, eliminating the need for screws, clips, or other complex mechanical attachment mechanisms

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If the blocking member is permanently fixed to the cover body, then it reliably blocks the mist outlet, but it cannot be removed for cleaning or replacement

Engineering Contradiction:

Improveblocking effectivenessVSAvoidcleanability

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The magnetic connection between the blocking member and cover body provides reliable attachment during use while allowing easy separation for cleaning or replacement, replacing permanent mechanical fastening with a controllable magnetic field

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

This application provides an inhalation device, and the device includes: a housing; an atomization structure, arranged in the housing and including a mist outlet; a cover body, movably connected to the housing; and a blocking member, arranged on the cover body, where when the cover body is configured to be in a first state, the blocking member is attached to the mist outlet and blocks the mist outlet; and when the cover body is configured to be in a second state, the blocking member is separated from the mist outlet. In this way, when the inhalation device is in use, the cover body is configured to be in the second state, and when the inhalation device is not in use, the cover body is configured to be in the first state. When the cover body is configured to be in the first state, the blocking member is attached to the mist outlet and blocks the mist outlet, so that an atomization medium in the housing is not evaporated through the mist outlet after passing through the atomization structure, thereby reducing a problem of a large deviation in an amount of mist sprayed.
