Abstract
The utility model provides a fire filter type self -rescue respirator, including the cover body and filter, the cover body with the filter is connected, the filter is kept away from the one end of the cover body is equipped with the air vent, the one end that the filter closely covers the body is equipped with the induction port, strains smoke stratification, dry layer from being equipped with in proper order between air vent to the induction port, strains the toxicant layer. The utility model discloses a fire filter type self -rescue respirator can effectually filter the harmful gas who produces in the conflagration, it is effectual to strain the poison, and weight is lighter, has increased the person's of wearing comfort, prevents to cover the backing sheet that the body is out of shape in the internal lateral wall setting of cover simultaneously for the leakproofness of respirator is better, and the comfort level is better, has reduced survivor's fear.
Description
Technical field
The utility model relates to a kind of respirator, refers to a kind of filtering respiratory protective devise for self-rescue from fire especially.
Background technology
Fire seizes countless life.Burn or heat radiation is died from according to statistics up to the victim of 85%, but the CO released when dying from building framework and ornament materials burning and poison gas.Most victim just suffocates before being burnt, and this can prevent.
The effective filtering CO of filtering respiratory protective devise for self-rescue from fire energy with canister and pernicious gas, anti-flaming thermal-insulation, escapes to people and provides chance from dense smoke and poison gas.Filtering respiratory protective devise for self-rescue from fire of the prior art generally includes canister and cover body composition, and filter toxic effect fruit is poor, and respirator is heavier.Face shield during use, face shield easily subsides, its sealing and comfortableness not good enough, when saving oneself, survivor is often at full stretch, increases the comfortableness of escape article and alleviates the weight of escape article, the fear that will reduce.
Utility model content
The utility model proposes a kind of filtering respiratory protective devise for self-rescue from fire, solve the problems such as malicious weak effect filtered by respirator of the prior art, and respirator is heavier, and sealing is poor, and comfort level is poor.
The technical solution of the utility model is achieved in that a kind of filtering respiratory protective devise for self-rescue from fire, comprise cover body and canister, described cover body is connected with described canister, described canister is provided with passage away from one end of described cover body, one end of the nearly cover body of described canister is provided with air entry, is provided with particulate filter, drying layer, filter poison oxidant layer between from passage to air entry successively.Particulate filter of the prior art is arranged between filter poison oxidant layer and air entry, and particulate filter is arranged on the service life that can extend drying layer between passage and drying layer by the utility model.
Further, screen pack is provided with between described particulate filter and drying layer.
Further, described particulate filter comprises a filter cotton.
Further, described drying layer comprises drier.
Further, described filter poison oxidant layer comprises hopcalite agent.
Further, described cover body madial wall is provided with the support chip preventing described cover body to be out of shape.Filtering respiratory protective devise for self-rescue from fire is when storing, generally can vacuumize to inside, because cover body is made up of silica gel or rubber, face shield after vacuumizing can be out of shape, the face shield be out of shape during use is difficult to recover, even cause and cannot recover, thus had a strong impact on the sealing of respirator, cause user to suck poison gas in use.The face shield simultaneously not adding support chip when in use canister can touch face, and hidden danger face being had be burned, when the utility model makes to use by arranging support chip, canister can not touch face, thus prevents from scalding.
Further, described drying layer is 2-4 centimetre along described passage to the thickness in described air entry direction, described filter poison oxidant layer along described passage to the thickness in described air entry direction be 2-4 centimetre.
Further, particulate filter, drying layer, filter poison oxidant layer, drying layer, filter poison oxidant layer is provided with between from passage to air entry successively.
Further, the quantity of described support chip is two pieces, is relatively arranged on the madial wall of described cover body.
The beneficial effects of the utility model are: filtering respiratory protective devise for self-rescue from fire of the present utility model can effectively filter the pernicious gas produced in fire, filter poison is effective, lighter in weight, add the comfort of wearer, the support chip preventing cover body to be out of shape is set at cover body madial wall simultaneously, make the better tightness of respirator, comfort level is better, decreases the fear of survivor.
