Fragrance Machine Atomization Design to Reduce Air Pump Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance machines have complex structures, generate significant noise due to high-speed airflow, and are inconvenient for refilling fragrance liquid during use.
Innovation Solution
A fragrance machine design with a housing that mounts the air pump in a cavity defined by a cover body and mounting seat, featuring an atomizing component with air and liquid spray holes for efficient atomization, and a detachable liquid storage system for easy refilling, along with a rechargeable power supply and integrated timing and lighting functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-speed airflow injection mode is used for atomization, then atomizing effect is improved, but noise generated by air pump operation increases
Solution Approach 1:
The air pump is extracted from the main housing body and placed in an independent noise-insulated compartment. This spatial separation allows the atomization function to maintain high-speed airflow performance while isolating the noise source from the user environment, effectively resolving the contradiction between atomizing effect and noise generation.
Solution Approach 2:
The patent employs a simple disposable liquid cartridge system that can be easily replaced. This allows the use of simple, effective atomization components without complex noise reduction mechanisms in the replaceable part, while the permanent housing contains the noise-insulated air pump. The separation of disposable atomization elements from the permanent noise-controlled structure resolves the contradiction.
2Ease of manufacture
If the fragrance machine uses a fixed structure, then manufacturing is simplified, but refilling fragrance liquid becomes inconvenient
Solution Approach 1:
The fragrance machine is segmented into a permanent housing containing the air pump and a detachable liquid cartridge. This segmentation allows the main body to maintain simple manufacturing while the cartridge provides easy refilling capability. The cartridge can be independently replaced without disassembling the entire device, resolving the contradiction between structural simplicity and refilling convenience.
3Ease of repair
If the air pump is mounted outside the housing, then maintenance is easier, but noise insulation is reduced
Solution Approach 1:
The air pump is extracted from the main housing chamber but not completely removed from the device. Instead, it is placed in a dedicated noise-insulated compartment that can be accessed for maintenance. This partial extraction maintains noise insulation during operation while providing access pathways for maintenance, resolving the contradiction between maintenance accessibility and noise insulation.
