When selecting a waterless nebulizer diffuser, noise level is often a major concern for many individuals. Effective noise control is a worldwide challenge that necessitates professional expertise and dedicated efforts. To minimize noise in waterless nebulizer diffusers, several options can be considered:
1）Optimize the structural design based on the characteristics of the housing material.
2）Reduce the noise generated by the diffuser’s components.
3）Select a housing material with excellent sound insulation properties.
To analyze the noise source of a portable waterless diffuser, a thorough examination of its structure is required.
The main noise sources in a waterless nebulizer diffuser are the nozzle and the air pump. The nozzle produces a crackling sound when liquid is atomized, while the air pump generates operational noise. Noise testing has revealed that the nozzle produces noise within the range of 30dBA (considered ultra-quiet), whereas the air pump generates noise ranging from 55-65dBA. Hence, the primary noise source is the air pump during its operation.
Here is the design structure of the air pump:
To mitigate the noise, several measures can be taken.
First, optimizing the atomization efficiency of the nozzle can help achieve a larger atomization volume while minimizing the air volume. This can be done by refining the design and ensuring efficient atomization of the liquid.
Second, selecting a suitable housing material and optimizing the structural design can contribute to noise reduction. The housing material should possess good sound insulation properties to minimize noise transmission.
Third, optimizing the specifications of the air pump can help reduce noise levels. This can involve selecting a quieter air pump model or making adjustments to the current pump’s design.
After implementing these optimization measures, the current target is to achieve a balance between atomization volume and noise at 4-5ml/h/42dBA. However, it is important to note that the atomization volume per hour may vary depending on the viscosity and volatility of different essential oils.
For continuous improvement, exploring new atomization methods and optimizing the inner structure of the air pump can further reduce noise levels.
