Dyson可净化周边空气的耳机专利 - 疫情当前，这个产品很是应景

疫情当前，如何更好地保护自己免受包括冠状病毒在内的的呼吸道和肺部病毒的侵扰，佩戴口罩是必不可少的。

Dayson于英国专利局申请了支持空气净化功能的双耳头戴式耳机，帮助用户同步实时营造局部净化空气空间。疫情过后，对于防止空气污染对健康的伤害，此款专利也提供了一个有意思也很有价值解决方案。

在耳机中有过滤装置并配备喷嘴(nozzle) 将过滤后空气供给用户。

以下为专利申请中的描述 -

Both earcups contain a motor that's connected to a fan-like propeller measuring 35-40mm. Each spin at about 12,000 rpm to draw about 1.4 liters of air per second into the headphones through a filter that particles -- typically dust and bacteria, although not specified in the patent -- cannot penetrate. The filtered air then journeys down each side of the mouthpiece, meeting in the middle, where a perforated air vent jets about 2.4 liters per second of clean oxygen toward the wearer's mouth. However, there is no reference to a battery, or any illustration where one might fit.

最早于2008年Dyson就申请了所谓“穿戴式空气净化装置”。

其原理，相当于是一个小型化的个人空气净化装置。作为Dayson众多专利的一部分，这款产品不一定会很快进入市场
