Problems solved by technology
Although the head-mounted purifier has incorporated the air-purifying function into the headphones, the air-purifying and conveying performance is limited because it can be used to filter pollutants from the fan-supplied air and to convey the filtered air to the user's space very small
In particular, this small available space will significantly limit the maximum flow and filtration efficiency due to the small available filter area

Embodiment Construction
[0058] A head-worn air purifier will now be described that offers several benefits over conventional wearable air purifiers. The term "air cleaner" as used herein refers to a device or system capable of removing pollutants from the air and emitting purified or filtered air. The term "head wearable" as used herein defines an article which is capable or adapted to be worn on the head of a user.
[0059] The head-mountable air purifier includes an earphone system including a pair of speaker assemblies mounted on a headband. A first speaker assembly is mounted on a first end of the headband and a second speaker assembly is mounted on an opposite second end of the headband. One or both of the first speaker assembly and the second speaker assembly then includes a filter assembly, an impeller for generating an air flow through the filter assembly, a motor arranged to drive the impeller, and an air filter assembly downstream of the filter assembly. An outlet for emitting a stream of...

Abstract
A head wearable air purifier 1000 comprising a first speaker assembly 1100a and a second speaker assembly 1100b, wherein the first speaker assembly comprises a speaker, a filter assembly, an impellerfor creating an airflow through the filter assembly, a motor arranged to drive the impeller, and an air outlet downstream from the filter assembly for emitting the filtered airflow from the speaker assembly. The impeller and the motor are disposed within an impeller casing. The first speaker assembly further comprises a housing containing the speaker, the filter assembly and the impeller casing, and the impeller casing is suspended within the housing by a plurality of resilient supports. The air outlet connects to a nozzle 1300, which is rotatable relative to the speaker housing.
Description
technical field [0001] The present invention relates to a wearable air purifier and in particular to a head-mounted air purifier. Background technique [0002] The problem of air pollution is becoming more and more serious and many air pollutants are known or suspected to be harmful to human health. The adverse effects that can be caused by air pollutants depend on the pollutant type and concentration, as well as the length of exposure to polluted air. For example, high air pollution levels can immediately lead to health problems, such as exacerbation of cardiovascular and respiratory diseases, while long-term exposure to polluted air can have permanent health effects, such as loss of lung capacity and lung function, and the development of diseases, such as asthma, bronchitis , emphysema, and possibly cancer. [0003] In places with particularly high levels of air pollution, many people have recognized the benefits of minimizing their exposure to these pollutants, and have...
