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

Anti-dust assisted respiartion head-shield

Art

The present invention relates to a kind of electric fan and filter of using to provide the head-shield of filtered air, especially can help people can also the light air crossed of breath purifying during work under the environment being full of dust, air quality difference, and then do not affect it and normally work, more avoid losing one's health because working under dust atmosphere for a long time.

Background technology

At present, mostly known anti-dust apparatus is the simple pattern of mouth mask, face shield, filter paper, and the full human body that leans on obtains the pure air after filtration air through filter paper mask for inhalation, causes user to feel with regard to occurring that breathing is tired at short notice.Meanwhile, apparatus is fixed on mouth nose, ear, the back side of head by elastic cord, rubber band, so that not only causes the discomfort of user's face by existing dust-proof apparatus mostly, can not guarantee to seal completely, and the turbid air sucking filtered still can be frequent.So that user needs often to adjust dust-proof apparatus, cause operating efficiency to reduce, affect productivity.Existing dust-proof apparatus also cannot protect eyes, head is not invaded and harassed by dust, and after user often takes off dust-proof apparatus, nose face is clean, but head, face are but full of ashes, causes degree of working actively to reduce, and cleaning head is time-consuming bothersome, and cost is quite high.Due to the above-mentioned defect of existing dust-proof instrument, no matter work personnel use, or abandon because of uncomfortable, all still can suck dust more or less, cause the healthy sequelae that cannot make up.

Summary of the invention

In order to overcome the comprehensive deficiency of the practicality of existing anti-dust apparatus, comfortableness, protection, the invention provides a kind of anti-dust assisted respiartion head-shield, this assisted respiartion head-shield can not only definitely effectively prevent user from sucking dust in environment, and increase user can be avoided in air-breathing to expend muscle power, long-time use can not feel well yet, effectively can promote the operating efficiency of user, lower the time cost of clean face, and people is completely free of work restriction that dust atmosphere causes and negative health effects.

The technical solution adopted for the present invention to solve the technical problems is: use portable power source to carry out drive fan, promote air through strobe utility (such as filter paper, filter cotton, active carbon), air after filtering is imported type semienclosed, transparent head-shield, head-shield can hang on shoulder, head-shield is provided with local openings or unidirectional (outwards) air valve (such as below mouth), promoted to enter head-shield by fan continually owing to purifying air, air pressure principle can ensure that the air of filtered in environment does not enter local openings or the Non-return air valve of head-shield; Head-shield can arrange the door of folding at face (face door), facilitates user dress head-shield or in use wipe the sweat to head or scratch where it itches; Also have that feature is head-shield braces, button, devil's glue or other device are firm is placed on user's shoulder, can allow the head of user and limbs freely activity, the visual field also not limited by head-shield.

The invention has the beneficial effects as follows, people can be completely free of work restriction that dust atmosphere causes and negative health effects, long-time use also can make user feel comfortably cool, promote work productivity, guarantee the health of labor author, increase work and the quality of life of user, use widely and can also reduce social medical treatment cost.

Detailed description of the invention

In FIG, portable power source (102) drives fan (103) through electric wire (103) and outside air is imported dust-proof head-shield (105) through air filter paper (104), head-shield only has an opening below user's oral area, the air of evolving can be full of in head-shield, discharge from opening, also squeeze outside air simultaneously, prevent outside air from entering from exhaust outlet.Firm for head-shield is placed on the shoulder of user by fixing braces (106).

In the embodiment depicted in figure 2, the head of user is shrouded completely in head-shield, simultaneously user to maintain whole body movable freely.

Be presented at the air induction conduit that the basis of Fig. 1 increases at Fig. 3, effect be fresh air conveying to appropriate position, avoid directly blowing facing to user's hindbrain, increase the comfort level that head-shield uses.

Fig. 4 is that the user having added air conduit uses schematic diagram.

Fig. 5 ~ 8 are front elevations, show the opening (503) of head-shield, in the below of user's oral area.Because head-shield is transparent, the fan (502) at the head-shield back side also can be seen in the Fig. 5 in front.Fig. 5 also show fixing braces (504,505).Fig. 6 uses schematic diagram from front display user.Fig. 7 adds left and right air conduit (301,702) and Non-return air valve (701) on the basis of Fig. 5.Non-return air valve is the replacement scheme of simple and easy exhaust outlet, can thoroughly avoid outside air to enter head-shield without filtration.Fig. 8 is that the user of Fig. 7 uses schematic diagram.

Fig. 9 ~ 12 are back views, and same Fig. 5 ~ 8 are similar, and fan (103) is positioned at the back side of head-shield (105), and left and right air conduit (301,702) can get around the back side of head and supply air to user's face.Figure 10,12 display head-shields can while airtight head spaces, and the head of user and hand can unrestricted activities.

Figure 13 ~ 16 are 45° angle oblique views of this invention.The fixing braces (106,502) in left and right can allow firm being placed on user's shoulder of head-shield.Air is sent to user's face left and right sides from hindbrain air inlet by left and right air conduit (301,702).Figure 14,16 is that user uses schematic diagram.

Figure 17 adds the face door (1701) of folding on the basis of side view 1, facilitates user sometimes need to scratch where it itches face, and conveniently dresses.Figure 18 is the position from front display folding face door (1701), and Figure 19 looks side ways direction from 45° angle, state when display folding face door (1701) is opened completely.
