Description

Life saving helmet

The present invention relates to a kind of life saving helmet, it mainly is the life saving helmet that a kind of inside is provided with automatic oxygen generator, and can or emergencies such as poison gas leaks take place at fire the time, for user's life-saving.

When fire takes place, the main cause that causes death or injure is burnt or is burnt to death, but owing to suck a large amount of dense smoke and the gas of stimulation, the victim is died of asphyxiation, or because in dense smoke, can't open eyes, can not find means of escape and cause death,, promptly become key issue with fire disaster escaping so how can avoid the threat of dense smoke.

Because present building materials mostly adopt chemicals, such as: polystyrene, poly-imines fat, plastics, polynary fat, nylon, timber etc., in case breaking out of fire, these building materials all can discharge a large amount of dense smoke and toxic gas, so relevant manufacturers design goes out multiple different emergency escape head-shield, in the hope of when the breaking out of fire, can supply user's life-saving.

But with regard to existing this type of emergency escape hood structure, it mainly can be divided into two types, wherein a kind of is the design of adopting filtering type, it is at the head-shield opening part band to be set, filter course or filtering tank in position are set then, and utilize suitable filtering material to filter extraneous dense smoke, and allow the user can keep the smoothness of breathing; Another kind then is an oxygen supply formula head-shield, and it is side joint one breather pipe outside head-shield, and disposes oxygen tank in addition, and when urgent head-shield is enclosed within head, opens the oxygen tank oxygen supply then; These two kinds of emergency escape head-shields all have its shortcoming to exist.

Head-shield with filtering type is seen it, it only can filter at the particulate material in the dense smoke, but the chemical gas that is produced when fire takes place but can't play a role in filtering, so this type of head-shield also is unable to cope with toxic gas in the present environment, certainly any substantive effect of more impossible performance when poison gas leaks.

As for oxygen supply formula head-shield, though it can solve the problem of toxic gas, but unmanageable problem is arranged for compressed air or oxygen, because this type of compressed air or oxygen all are difficult to store, also might meet accident at ordinary times even, the operating procedure of this type of device is quite numerous and diverse simultaneously, can't effectively deal with emergency situations; Moreover its volume carries inconvenience too greatly, and the user also can not be with it at one's side at any time, so its service efficiency is lower; It is in use handicapped again, when meeting accident incident, very likely causes other harm in flurried; In addition, when it is breathed for the user with pure oxygen,, can have influence on user's normal behaviour even, and unforeseen situation takes place if the user without suitable training, will inevitably produce overwrought physiological phenomenon because oxygen concentration is too high; Obviously this type of emergency escape head-shield does not also have practical value.

Above-mentioned two kinds of existing emergency escape head-shields all have its structural disappearance, and the user can't be provided preferable practicality, and it obviously has the necessity that is improved.
