Abstract
The utility model relates to a respiratory filter, in particular to an activated-carbon filter box capable of being used as a protective mask. A casing containing activated-carbon filter element is used as a main unit of the activated-carbon filter box and consists of a casing base and a filter box cover which is detachably connected with the casing base, a joint communicated with the protective mask fixedly is arranged at the bottom of the casing base, and at least one hole is arranged on the top wall of the filter box cover. The activated-carbon filter box has the advantages that an external compressed air source can be used directly so that affection of the air source on construction site is avoided; the activated-carbon filter element can be changed independently so that cost can be saved; and the activated-carbon filter box can be used as a general protective mask or general dustproof mask after an air pipeline component is removed, a seal cap is detached and different activated-carbon filter element or filter cotton is changed, multifunction is realized and requirements of different construction environments are met.
Description
Technical field
The utility model relates to a kind of breathing circuit filter, is specifically related to a kind of active carbon filter box that is used for protective face mask.
Background technology
Present anti-poison respirator is to be main with portable anti-poison respirator, is to filter through flank two active carbons filter box, breathes the air of site environment.Existing filter cartridge generally is a box body that is equipped with active carbon, and a side is connected with the gas mask flank, and opposite side is directly connected with control, when needing to change filter cartridge is pulled down new the getting final product of replacement.
It is through being usually used in the more factory of dry type spraying room, enginerring works, building stones, dust processing factory or other dust-likes etc.When in above-mentioned processing factory, using, protective face mask generally uses inner circulating air, promptly directly filters from peripheral site environment and obtains the required air of human body respiration.And such mode has following shortcoming: the one, and fresh air make up is few, and air is dirty, uses portable anti-poison respirator, can weaken the safeguard function of human body, even can damage.The 2nd, outside the activated carbon filtration box was exposed to, the space between its active carbon let coating cloud, dust be stained with easily and blocks, and increased respiratory resistance; And the steam that produces when breathing also makes charcoal absorption easily, makes active carbon saturated, reduces the service life of active carbon.Long-time simultaneously use is prone to spoiled smelly, wears uncomfortable.So just need often to change filter cartridge.
Summary of the invention
The purpose of the utility model is the weak point according to above-mentioned prior art; A kind of active carbon filter box that can be used for protective face mask is provided; Housing and the active carbon filter core of this active carbon filter box through the branch body structure is set, and a side is provided with two kinds of perforates on housing, can realize directly breathing peripheral site environment air, rely on the source of the gas air feed to breathe two kinds of breathing patterns; Adaptability is wider, and the life-span is longer.
The utility model purpose realizes being accomplished by following technical scheme:
A kind of active carbon filter box that can be used for protective face mask; Be installed on the gas mask front side; It is characterized in that: said active carbon filter box with one wherein be equipped with active carbon filter core housing as its main body; Said housing is made up of the filtration lid of housing base and the said housing base of detachable connection, and the bottom of said housing base is provided with and is used for being communicated with fixing interface with said gas mask, offers at least one perforate on the said filter cartridge lid top wall.
Be provided with one deck filter cotton in the said active carbon filter box, said filter cotton is arranged between said active carbon filter core and the said filtration lid.
The sidewall week of said filtration lid is edge and assembling with it on said housing base.
Edge is threaded on the sidewall of said filtration lid and the said housing base.
Said filter cartridge covers the perforate of offering and comprises: a source of the gas connects the hole, is used for being communicated with the source of the gas of air feed; At least one venthole is used for directly being communicated with outside air.
Said source of the gas connects the center that the hole is arranged at said filter cartridge lid top wall; Said venthole connects the hole periphery in said source of the gas and is uniformly distributed with; And the inboard detachable sealing buckle closure that is provided with the said venthole of a covering of said filtration lid; This sealing buckle closure center offers a corresponding said opening that connects the hole, and its outer rim is fitted with said filtration lid and sealed, the venthole that covers with the said filter cartridge of shutoff.
Said filtration lid inboard is coaxially arranged with a ring groove, and said venthole is uniformly distributed with in this annular recess, and said sealing buckle closure outer rim spiral-lock is therewith in the annular recess and the sealing of fitting.
Said source of the gas connects the hole and has internal thread, is used for being connected with gas-pipe thread.
The utility model has the advantages that:
Can directly use the external compressed air source, not receive the influence of job site air source.
Active carbon inner core or filter cartridge can be changed separately, practice thrift cost.
Remove the supply air line parts, take off the close buckle closure of envelope, change the different activity charcoal and cross filter core or filter cotton, both can do general anti-poison respirator or general anti-dust respirator use, on function, realized variation, satisfy the demand of different construction environments.
