Abstract

A portable toxic smoke prevention helmet is composed of breathing devices, a folding device, an observation device and a sealing device. Once encountering emergent fire disasters, a user can unfold the helmet with the built-in activated carbon breathing device and the built-in floating ball type breathing device and cover the head with the helmet, toxic smoke is completely prevented from being inhaled into the lungs and causing death under the condition that the head is protected by the portable anti-toxin helmet, and therefore the user can have time to escape or to wait for being rescued by firefighters.

Description

Portable protective hood

Affiliated technical field:

The present invention relates to the portable protective hood in a kind of fire-extinguishing and lifesaving field, by using this device, in the time of can avoiding happening suddenly fire, poisonous dense smoke is encroached on human respiratory, causes the serious consequence of death by suffocation, help people to flee from smoothly the scene of a fire, reach the object of lifesaving.

background technology:

At present, known protective hood is not adopted with universal and is used by people because of heavier and expensive, and the toxic smoke of burst during fire taken the fatal killer of people's life often by force, considerable fire fatality person all in fleeing from way corridor mouth because sucking poisonous dense smoke death by suffocation.

Summary of the invention:

For prevent people in burst fire because of pyrotechnics envelope road, the tragedy of the caused death by suffocation of cannot escaping occurs often.The invention provides a kind of portable protective hood, under emergency, people are as long as be enclosed within " head-shield " on head, auxiliary facility in " head-shield " will be isolated by " toxic smoke " and indicator of trapped personnel, for helping people flee the scene rapidly or wait for rescue the valuable time of striving for, equally also can greatly reduce the death rate that indicator of trapped personnel is gone through death by suffocation.

The present invention solves the scheme that its technical problem adopts:

In public places, local or the eye-catching place at home that crowd gathers, lay one and can deposit the portable head-shield that (as required) is several or dozens of can be folded up in, once relevant place burst fire, and the intensity of a fire is violent, pyrotechnics envelope road, Dark smoke billows, and people cannot escape, foreign aid does not arrive in the very nick of time again, indicator of trapped personnel can be opened storage bin, takes out portable protective hood, just can help people isolated with dense smoke timely, prevent the generation of suffocation accident, for escaping voluntarily and waiting for rescue the valuable time of striving for.

The invention has the beneficial effects as follows:

When people happen suddenly weight, wildfire in relevant place, because Dark smoke billows, the people's death by suffocation that very easily causes escape or wait for rescue, for avoiding the generation of this type of accident, use the portable protective hood of the present invention just can be timely that toxic smoke and people's respiratory system is isolated, reach the object of lifesaving.The present invention is simple in structure, only uses the head-shield of a simple type, by tidal air filtration obstruct accessory and head-shield folding device, is combined.

Specific implementation method:

In Fig. 1, with canvas, be first sewn into a head-shield (3) that is slightly larger than people's area of bed, its top install a circular funnel-form wide at the top and narrow at the bottom, under have device hole pipe, with a lightweight ball float (1), when people exhales, ball float floats above, when air-breathing, ball float falls, and just in time covers hole, prevents that smog from entering.Above just above, open a rectangle openning, making is a frame device of putting white glass, built-in white glass (2), below dead ahead, open equally a rectangle openning, make the frame what a puts active carbon, in frame, settle both sides to have the getter device (4) of net, end opening at head-shield stays a breach (5) that is slightly larger than the number of people, make the cloth of strip in the above, inner cover elastic cord (6), seals.

Accompanying drawing explanation:

Fig. 1 is the front view of portable protective hood.

Fig. 2 is the left view of portable protective hood.

In Fig. 1, Fig. 2

1, be float-ball type breath device.

2, be observation transparent glass sheet.

3, be canvas head-shield.
