Dustproof breathing assisting hood

Abstract

The invention discloses a dustproof breathing assisting hood with an air filtering system. Air is guided into a filtering device (such as filtering paper and filtering cotton) through a fixed or movable power source and an electric device (such as a fan) to be delivered into the hood to be breathed by a user. The purified air continuously enters the hood to be used for squeezing and prevent unfiltered air from entering the hood from a local air exhausting opening or a one-way air valve of the hood. The hood made of transparent materials is arranged on the shoulders of the user, the head and the body of the user can freely move, and the view field is not limited. The dustproof hood is used for replacing an existing dustproof utensil such as a mask and a face mask, the breathing difficulty of the user is lowered, the long-time wearing comfort degree of the user is increased, dust is more effectively prevented from being sucked, and clean protection for the whole head is more effectively achieved. The main object is a person who must work for a long time in the serious air pollution environment such as a dust-filled factory and a dust-filled pit. The health of the user is guaranteed, and the productivity of the user is improved.

Description

Technical field [0001] The invention relates to a hood that uses an electric fan and a filter device to provide filtered air, especially to help people breathe the purified air easily when working in an environment full of dust and poor air quality, without affecting their Work normally, and avoid losing health due to long-term work in a dusty environment. Background technique [0002] At present, most of the known anti-dust appliances are simple masks, face shields, and filter papers, all relying on the human body to inhale air through the filter paper into the mask to obtain filtered clean air, causing users to feel tired in a short period of time. At the same time, most of the existing dust-proof appliances rely on elastic bands and rubber bands to fix the appliances on the mouth, nose, ears, and back of the head, so that it not only causes discomfort to the user's face, but also cannot ensure complete sealing.

AI Technical Summary

Problems solved by technology

[0002] At present, most of the known anti-dust appliances are simple masks, masks, and filter papers, all of which rely on the human body to inhale the air through the filter paper into the mask to obtain filtered clean air, causing users to feel tired in a short period of time.

At the same time, most of the existing dust-proof appliances rely on elastic bands and rubber bands to fix the appliances on the mouth, nose, ears, and back of the head, so that it not only causes discomfort to the user's face, but also cannot ensure complete sealing. Occurs from time to time

As a result, users need to frequently adjust dust-proof appliances, resulting in reduced work efficiency and affecting productivity

Existing dust-proof equipment cannot protect the eyes and head from dust intrusion. After the user takes off the dust-proof equipment, the nose and mouth are clean, but the head and face are full of dust, which reduces the enthusiasm for work. The head is time-consuming and costly

Due to the above-mentioned defects of existing dust-proof tools, no matter whether workers use them or discard them due to discomfort, they will still inhale more or less dust, causing irreparable health sequelae
