Multifunctional isolation-level protective cap and sealing method

Abstract

The invention discloses a multifunctional isolation-level protective cap and a sealing method, and especially relates to a safety helmet capable of preventing infectious diseases, poison, dust, haze and the like. The helmet comprises a safety helmet body, a neck sealing cover, an exhaust port, an exhaust filtering cover, a perspective area, an air inlet, an air inlet fan, an air inlet flow expanding cavity, an air inlet filtering cover, a battery box, a safety helmet lining, an air inlet filtering cover support and an exhaust filtering cover support. The multifunctional isolation-level protective cap has the following advantages that: the whole head is completely sealed in the protective cap without wearing a mask, so that the goggles are completely protected, and the forced filtration airinlet fan is installed, so that air in the helmet flows, sufficient fresh air is provided all the time, the problems of difficulty in breathing and stuffiness are thoroughly solved, and the head injury caused by collision and foreign matter smashing can be borne or reduced.

Description

technical field [0001] The invention relates to the field of respiratory and head protection, in particular to a multi-functional safety protective cap for preventing infectious diseases, poisonous gas, dust and haze at an isolation level. Background technique [0002] The current respiratory virus protection, anti-gas, dust-proof, anti-smog, etc. are all protected by wearing special masks and goggles. Although it is simple and easy to do, there are many problems, such as the position of the nose clip is easy to leak air , Hair and ears without protection can easily hide viruses and dust, which poses a great hidden danger to virus protection, especially those viruses that have no specific drugs to treat them, such as SASR virus, Ebola virus, and new coronary pneumonia virus. life threatening. Moreover, the masks are sealed by being close to the face, which will cause great damage to the face, especially some parts of the bridge of the nose are sealed by metal clips, and the...

AI Technical Summary

Problems solved by technology

[0005] In terms of helmets, some venues need to wear not only helmets but also masks, which will cause most of the head to be airtight and stuffy, and wearing masks will make breathing difficult and increase fatigue

[0006] In terms of traffic safety protection, we only wear helmets for protection, but there are a lot of dust and smog on the road, and the current helmets do not have protection against dust and smog.
