Air filtering device with helical structure and helical filtering nose plug

Abstract

The invention discloses an air filtering device with a helical structure and a helical filtering nose plug. The device comprises a helical structure and an adhesive medium, wherein the helical structure comprises a helical pipe wall and helical ribs mounted on the inner wall of the pipe wall; and the inner wall of the helical pipe wall and the helical ribs are coated with the adhesive medium. The nose plug comprises two helical structures, a connecting band and an adhesive medium, wherein the two helical structures are respectively arranged on left and right nose cavities; the connecting band is used for controlling the placing position of the nose plug, and moreover, is convenient to wear and use; and the helical structures can induce passing gas to form vortex, promote inhalable particles carried in air to move towards the inner wall of the helical pipe and the helical ribs, and adhere inhalable particles to the degradable adhesive medium coated on the inner wall of the helical pipe and the helical ribs, so that the function of filtering off inhalable particles in the air is realized, air inhaled into the body is purified, and the influence of harmful particles on the human body is inhibited or relieved.

Description

technical field [0001] The invention relates to a particle removal device, in particular to an air filter device with a spiral structure and a spiral filter nasal plug. technical background [0002] With the increasing air pollution, it has become a common demand to filter the particulate matter in the air to prevent it from entering the human body. Especially in recent years, fine particle pollution such as PM2.5 has received more and more attention, and traditional masks and other equipment have become increasingly difficult to meet the demand. [0003] At present, masks such as N95 and other grades mainly based on electrostatic filter pure cotton or composite materials are usually used. Although they can achieve a filtering effect of 95%, they have large breathing resistance, which affects the wearer's experience, and is inconvenient in such as teaching. , meetings and other occasions. There are also similar nasal particle filter devices, which are generally composed of...

Problems solved by technology

Especially in recent years, fine particle pollution such as PM2.5 has received more and more attention, and traditional masks and other equipment have become increasingly difficult to meet the demand

[0003] At present, masks such as N95 and other grades mainly based on electrostatic filter pure cotton or composite materials are usually used. Although they can achieve a filtering effect of 95%, they have large breathing resistance, which affects the wearer's experience, and is inconvenient in such as teaching. , meetings and other occasions

There are also similar nasal particle filter devices, which are generally composed of polymer materials such as polyurethane and filter materials such as plant fibers and non-woven fabrics, which solve the problem of wearing occasions, but because the filter part of the nasal filter device is relatively small , it is difficult to prepare complex filter components, so it is difficult to filter PM2.5 particulate matter; and because it uses filter materials, it cannot solve the problem of large breathing resistance
