Problems solved by technology

These large-pore filters are usually not effective at filtering fine particles, such as PM2.5
Even some non-woven micron-scale fibers, such as HEPA (high-efficiency particulate air) filters, when used in the filter of the nostrils, the air flow through the filter is strongly restricted due to the small area, making the user uncomfortable

Embodiment

[0032] Such as Figure 1-7 As shown, the nasal breathing filter cover includes a main part 1 and a filter screen 2 arranged at one end of the main part. Wherein, the main part is placed in the nostril to play the role of support and sealing, avoiding the gap between the nostril and the outer wall of the main part, and ensuring the sealing; as an option, the main part is made of elastic material , for example: silicone. However the color of the main piece can be transparent or the color of the skin. Its shape and size can be changed to suit the comfort needs of the user. The filter screen is mainly used for filtering air, and as an option, the filter screen is a high-efficiency filter screen (HEPA filter screen) or a nanofiber filter screen. According to the target pollutant size and filtration efficiency requirements, the filter screen can be designed with various mesh sizes and multi-layer combinations.

[0033] Specifically, the main part includes two installation tubes ...

Abstract

The invention discloses a nose breathing filtration cover. The problems that an existing nose filtration device is small in superficial area and large in resistance are solved. The nose breathing filtration cover comprises a main part having the placement, supporting and sealing effect and a filtering net installed on the main part. A blank between a mask and a nasal cavity filter is filled through the nose breathing filtration cover. The nose breathing filtration cover has the beneficial effects of high filtration efficiency of the mask and tight sealing of the nasal cavity filter, and a user feels comfortable and the nose breathing filtration cover is attractive during dressing.

Description

technical field [0001] The invention relates to a nasal breathing filter cover. Background technique [0002] Air pollution, such as smog, carries high concentrations of particulate matter (PM) including heavy metals, toxic chemicals and compounds, bacteria and viruses. These pollutants often come from industrial activities, coal burning, vehicle exhaust and other sources of pollution. Particulate matter is the deadliest form of air pollution, due to its deep penetration into the lungs and blood, if they are not filtered from people's breath, they can cause permanent DNA mutations, causing heart disease, respiratory diseases, cancer and premature death. Commonly used personal respiratory protection equipment includes masks and nasal filters. Most masks on the market are not designed to filter particulate air pollutants. Only a few brands of masks are designed to filter particulate matter from air pollution and can filter out 95% or more of particulate matter from smog, e...
