In-nose type air filter facilitating food intake

Abstract

An in-nose type air filter facilitating food intake comprises an air filtering box, air exchange pipes, self-closed breather valves, a filtering element, in-nose air exchange pipes, nose supporting ropes, in-nose caps, a nose supporting sleeve, ear hanging ropes and the like. According to the in-nose type air filter facilitating food intake is worn by a wearer, when the nostrils are used for inhaling, after air is filtered by the filtering element, the air enters the air filtering box, the air exchange pipes and the in-nose air exchange pipes from an air inlet, the air is inhaled into the body, and the air cannot be inhaled into the air filtering box from air outlets; when the nostrils are used for expiration, waste gas enters the in-nose air exchange pipes, the air exchange pipes and theair filtering box from the body and escapes out of the air filtering box from the air outlets and the air inlet, and the harm of hazardous gas to the wearer is reduced. The air exchange pipes are inserted into the nostrils of the wearer and are closely attached to the nostrils, the air which is not filtered cannot enter the body from the nostrils, and the protection effect is good; and when the wearer takes food, only the nostrils are used for breathing, the mouth is not used for breathing, purified air can be breathed during food intake, and the wearer continues to be protected.

Description

technical field [0001] The invention relates to an air filter, in particular to a nasal air filter which is convenient for eating by inserting one end of an air inlet and outlet tube into a nostril. Background technique [0002] At present, with the development of urbanization and industrialization, automobile exhaust pollution, industrial production pollution and home decoration pollution are becoming more and more serious. People are vulnerable to polluted air whether they are outdoors or indoors. more serious. Allergens such as smog, dust, pollen, mites, and irritating gases are inhaled into the respiratory system, causing allergic rhinitis, asthma, etc. The virus is inhaled and makes people sick. [0003] To avoid inhalation of toxic and harmful air into the body, people use various masks to protect themselves. Patent No. 201320477806.0 discloses a nasal plug-type air filter box that is inserted into the nostrils to fully filter the air. Patent No. 201580003194.3 disc...

AI Technical Summary

Problems solved by technology

Disposable invisible filter nasal congestion filter material is too small, the protection time is short, the protection effect is not good, it can only be used once, the price is high and the economy is poor, and it has not become the mainstream

[0005] More importantly, most masks cover both the nostrils and the mouth, making it inconvenient to speak and eat. Especially when eating, the masks must be removed, exposing people to toxic and harmful air, and the protective effect is drastically reduced
