Abstract

The utility model discloses a full-view mask of an emergency escape breathing device. The full-view mask comprises a hood and an air supply valve, an expiratory valve and windows which are arranged on the hood, wherein a front window, a rear window and side windows positioned on two sides are arranged around the hood. The air supply valve and the expiratory valve are arranged on the front window. The full-view mask of the emergency escape breathing device has the characteristics of wide visual range and convenience and safety in use, and is widely applied to the escape breathing device.

Description

The EEBD whole vision mask

Technical field

The utility model relates to the respirator in a kind of fire-extinguishing and lifesaving equipment, refers in particular to the face shield that is used on the EEBD.

Background technology

Along with people's is to the improve of fire-fighting awareness of safety, is used for from the scene of fire or poisonous gas leakage has become a lot of families for people provide the escape apparatus of cleaning breathing gas when fleeing from, particularly is in people's in the skyscraper the indispensable instrument of escape.Escape apparatus is generally by air bottle, and control of breathing device and breathing mask are formed.Wherein breathing mask is processed with fire proofing material, comprises a fan cleaning, bright rectangle observation window on the breathing mask, and steam supply valve and outlet valve are installed on observation window.People's breathing mask during escaping can be used for a protection of sealing relatively to escape personnel's head being provided; People's face and face are escaped injury; Observation window then can be used for making the people in the escape process, can keep good sight line; Steam supply valve is connected with steel cylinder through air supply pipe and valve body and is used to provide required cleaning tidal air of when escape, and outlet valve is used for the gas that the people breathes out is discharged outside the breathing mask.Though existing breathing mask can help the escape personnel from the on-the-spot escape of disaster, because of its form is merely a fan rectangular window, then has the vision blind area; When emergency situation took place, because of circumstance complication, dangerous fatal accident meeting took place at any time; This just requires the escape personnel can observe the four sides, has keen ears, but because of the existence of haplopia window vision blind area; The probability of escape is reduced greatly, thus the breathing mask of this haplopia window exist visual range narrow, use unsafe defective.

The utility model content

The utility model technical problem to be solved provides a kind of visual range EEBD whole vision mask wide, safe in utilization.

In order to solve the problems of the technologies described above the EEBD whole vision mask of the utility model; Comprise head-shield and be arranged at steam supply valve, outlet valve and the form on the head-shield, be provided with preceding form, rear view window around ground around the said head-shield and be positioned at the side-looking window of both sides.

Owing to around head-shield, be provided with preceding form, rear view window and be positioned at the side-looking window of both sides around ground; Then more open sight line is provided in the escape process for the escape personnel; Satisfied the various visual angles requirement of escape personnel when escape; The escape personnel can in time be observed and capture site information from various visual angles in the escape process, thereby in time avert danger factor, select the escape route of safety exactly.Therefore the setting of many forms has overcome original haplopia window that existing visual range is set is narrow, uses unsafe defective, and it is wide to have visual range, safe advantage easy to use.

Description of drawings

Be described further below in conjunction with accompanying drawing and the specific embodiment EEBD whole vision mask the utility model.

Fig. 1 is the work structuring sketch map of this a kind of specific embodiment;

Fig. 2 is the rearview corresponding to Fig. 1.

Among the figure: 1-head-shield, 2-steam supply valve, 3-outlet valve, form before the 4-side-looking window, 5-, 6-rear view window, 7-pressure-reducing valve, 8-Pressure gauge, 9-bottle valve, 10-steel cylinder, 11-air supply pipe.

The specific embodiment

In Fig. 1, EEBD whole vision mask shown in Figure 2; The side-looking window 4 of form 5, rear view window 6 and both sides before around head-shield 1, being provided with around ground successively, form all adopts transparent insulate material to process, on the head-shield 1 through this fan forms and be provided with after; Then realized and for the escape personnel more open sight line to be provided in the escape process; The escape personnel can in time be observed and capture site information in the escape process, thereby in time avert danger factor, select the escape route of safety exactly; Greatly increased the escape probability, therefore this many forms breathing mask has visual range advantage wide, safe in utilization.Preceding form 4 is provided with steam supply valve 2 and outlet valve 3; Wherein steam supply valve 2 is the check valve that an air-breathing conducting, expiration end; Steam supply valve 2 is connected with steel cylinder 10 through air supply pipe 11, pressure-reducing valve 7, bottle valve 9 and is used to provide required cleaning tidal air of when escape; Outlet valve 3 is an expiration conducting, the air-breathing check valve that ends, and is used for the gas that the people breathes out is discharged outside the breathing mask.

When escape or demonstration, air supply pipe 11 1 ends are connected on the steam supply valve 2, air supply pipe 11 other ends are linked to each other with steel cylinder 10 through pressure-reducing valve 7 and bottle valve 9; Open bottle valve 9 and adjust pressure-reducing valve 7, observe pressure pointer indicating value to suitable scale, steel cylinder 10 is carried on the back in the back through Pressure gauge 8; Head-shield 1 is placed in the head part; And form 5 links to each other steam supply valve 2 facing to the human face before making with population, and outlet valve 3 is linked to each other with the people nostril; The expiratory phase coordinative operation of the air-breathing and nose through population so just can guarantee in the escape process suction to clean air in the steel cylinder 10.

Above-mentioned some preferred implementations of only enumerating the utility model EEBD whole vision mask, but be not limited to this.Under the situation of the utility model basic principle, also can do some conversion and improvement.For example, the quantity that is provided with of viewing window not only is limited to four fans, also can be two fans, three fans or more fans, and so on.So long as head-shield is provided with the protection domain that the arrangement of many fan forms all is regarded as falling into the utility model.
