Description
Technical field
This utility model relates to gas generator technology field, particularly relates to a kind of two-way ignition type gas generator.
Background technology
Air bag is very important safety device on automobile, and when automobile has an accident, gas generator is to airbag inflated, it is possible to effectively reduces the accident injury to human body, thus protects the life security of driver and motroist.Common gas generator principle is all igniter (ignitron) igniting, and combustion-supporting medicine burns and gas generant composition in accordance of igniting, and produces a large amount of gas after gas generant composition in accordance burning, thus to airbag aeration.The most common gas generator be all pass through burning aerogenesis or from center to the aerogenesis that around burns, some are needed quickly, for the large-scale air bag of efficient expansion, existing gas generator gas producing efficiency is on the low side, it is impossible to meet large-scale air bag rapid expanding demand.
Such as Chinese Patent Application No. is CN201520453989.1, filing date on June 29th, 2015, and open a kind of automobile safety air bag gas generator, including shell, gas generant composition in accordance, ignitron, fixture and automatic ignition medicine；Enclosure forms airtight combustor；Gas generant composition in accordance and ignitron may be contained within the combustor of shell；Fixture is positioned at described combustor, and is fixed on outer casing inner wall；Fixture is internally formed lock chamber, and fixture has multiple connection lock chamber and the mesh of combustor；Automatic ignition medicine is arranged at the interior lock chamber of described fixture.After the middle part ignitron igniting of this kind of gas generator, igniting to surrounding centre, gas producing efficiency is low.
Utility model content
This utility model is in order to solve the above-mentioned problems in the prior art, it is provided that a kind of two-way aerogenesis that ignites, and improves the gas generator of gas producing efficiency.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of two-way ignition type gas generator, including housing, one end of described housing is provided with igniting base, the other end of housing is provided with end cap, combustor it is provided with in housing, described igniting outer socket end is provided with ignitron, described igniting base the inner and combustion chamber, it is provided with combustion-supporting medicine in igniting base, described housing is provided with some and combustion chamber venthole, the inner side of described venthole is provided with aluminum paper tinsel, the annular aerogenesis tablet of some coaxial overlappings it is provided with in described combustor, the centre bore of annular aerogenesis tablet connects formation air guide channel, it is provided with stage clip between described annular aerogenesis tablet and end cap, it is filled with graininess gas generant composition in accordance between described annular aerogenesis tablet and igniting base, the medial center of described end cap is provided with cavity, described cavity connects with air guide channel, combustion-supporting medicine it is provided with in described cavity.Ignitron is lighted a fire, produce in steam enters into combustor after the combustion of combustion-supporting guiding drug and light graininess gas generant composition in accordance, graininess gas generant composition in accordance is burnt, on the one hand annular aerogenesis tablet is ignited, the most substantial amounts of steam fires the combustion-supporting guiding drug in cavity through air guide channel, and combustion-supporting medicine is the annular aerogenesis tablet of the other end, and now in combustor, the annular aerogenesis tablet at two ends burns aerogenesis simultaneously, a large amount of gases enter in air bag after breaking through aluminium foil at steam vent so that air bag fast aeration expands.
As preferably, described case inside is provided with annular filter net.On the one hand gas can be lowered the temperature by annular filter net, on the other hand can effectively filter the waste residue after gas generant composition in accordance burning.
As preferably, being provided with dividing plate in described igniting base, described dividing plate is provided with some air inlets, and the lateral surface of described dividing plate is provided with aluminium foil, the outside being positioned at dividing plate in described igniting base is additionally provided with butterfly plate, and the center of described butterfly plate is provided with the gather qi together hole coaxial with air guide channel.Combustion-supporting medicine burning in igniting base, steam breaks through aluminium foil in entering air inlet, and steam moves quickly through after gather qi together hole is assembled in air guide channel enters cavity and lights combustion-supporting medicine.
As preferably, in described igniting base, in cavity, it is equipped with desiccant.Combustion-supporting medicine is played desiccation by desiccant.
Therefore, this utility model has the two-way aerogenesis that ignites, and improves the beneficial effect of gas producing efficiency.
