Description
Technical field
The utility model relates to a kind of containing the breathing apparatus for airbag, for airbag for storing required gas.
Background technology
The utility model is mainly based on following background and technology:
Daily life is with in work, and people often have in the face of the environment of poisonous and harmful air sometimes.Such as:
1), in living at home, in order to kill indoor mosquitos and flies winged insect, need in family, have people to spray poisonous spray when closing the doors and windows;
2) in order to kill the mosquitos and flies winged insect in corridor, staff is needed to spray poisonous spray when closing corridor;
3), in order to interior decoration, during painter's operation, have in the face of pungent paint smell;
4), when scientific research personnel does the experiment relating to toxic and harmful, the danger sucking pernicious gas is also faced;
5) need to avoid the gas of characteristics of contaminated respiratory droplets to be directly discharged in air sometimes to go, such as: in special industry, need the change avoiding the gas of characteristics of contaminated respiratory droplets to working environment air atmosphere.
Relevant example is too numerous to enumerate.The conventional measure that present people tackle this poisonous and harmful air ambient is that band muzzles; But mouth mask cannot stop some particle or aerosol.
Therefore, be the environment of reply poisonous and harmful air, the utility model have selected with the technology path for airbag behaviour body air feed, protects the healthy of self.
Number of patent application is the patent of CN03231859, proposes a kind of inhalation device.This device comprises face shield, check valve and gas-storing bag, and this is a kind of apparatus of oxygen supply being used in medical instruments field, and such device can play a role at medical field, and but can not be directly used in the environment of reply poisonous and harmful air, reason is:
1) allowing workman wear inhalation device work under poisonous and harmful air ambient, is unpractical.
2) due to the particularity in medical field use and oxygen, there is various ways can increase pressure for the oxygen of gas-storing bag, promote gas-storing bag to face shield delivering oxygen.Conveniently carry, reduce costs, for gas-storing bag increases stressed mode in these medical fields, be not suitable for the environment being applied to tackle poisonous and harmful air.
3) mask designs of this inhalation device is open, and this type of face shield is not suitable for being applied to operation in poisonous and harmful environment.
Like this, the utility model needs emphasis to resolve how from the technical problem for airbag air-breathing, comprising:
1) the need of the gas increase pressure for supplying in airbag? how do to be the gas increase pressure for airbag?
2) if for the air pressure in airbag not higher than ambient pressure, how gas is deposited from obtaining institute for airbag?
3) if from for airbag gas that inspiration is deposited, likely air supply opening can be blocked for after airbag distortion under normal pressure, how does this problem solve?
In addition, also to consider:
1) how for supplying air bag inflator?
2) if in time for inhaling inflation for airbag, how can not tackle poisonous and hazardous air ambient temporarily?
3) waste gas that how human body is breathed out?
Utility model content
In order to breathe pure and fresh air in the environment of poisonous and harmful air, the utility model proposes a kind of containing the breathing apparatus for airbag.
Of the present utility model containing for the breathing apparatus of airbag, comprising: air intake duct, for airbag, respirator, its feature: fresh air is pre-stored in in airbag, and user is pre-stored in for the fresh air in airbag by respirator inspiration; Between the air supply opening supplying airbag and the air inlet of respirator, connect with air intake duct, and the inlet valve of one-way ventilating has been installed.
Described inlet valve contains an air inlet and a gas outlet; When low pressure appears in the gas outlet of inlet valve, inlet valve is opened automatically, and gas flows to gas outlet from air inlet by inlet valve; When the air pressure of gas outlet is not less than the air pressure of air inlet, inlet valve cuts out automatically; Inlet valve is arranged on the air supply opening place for airbag, or is embedded in air intake duct, or is arranged on the air inlet place of respirator, can be also structurally an entirety with the air inlet of respirator.
Described respirator, for being the mouth of people or nose air feed, have resistance to deformation support in respirator or be made up of resistance to deformation material, the cover of respirator is airtight, when wearing human body air-breathing after respirator, can form low pressure, thus inspiration is for the gas in airbag in air-suction cover.In order to increase sealing and the comfortableness of respirator, at the position of respirator and contact human skin, bed course can be housed further.Described respirator can be nose cup; After wearing, human body by nose cup from for airbag inspiration gas, by waste gas in face exhalation body.In order to ensure that air feed is unimpeded, described adds air supply channel in airbag, and air supply channel is connected with air supply opening; Air supply channel can be the pipeline that sidewall has multiple pore, also can be the space that an air that support is propped up can circulate.
