The filtrating smoke dust film layer 4, filter pulp layer 603, link block 7 and gag lever post 8 of the utility model can be in market or privates
People orders gained.
Referring to Fig.1-3, a kind of nasal obstruction smoke filter, including shell 1, thread groove 101, snap ring 2, obstruction plate 3, flue dust mistake
Filter membranous layer 4, aperture 5, filtering table 6, screw thread layer 601, sieve 602, filter pulp layer 603, link block 7 and gag lever post 8, shell 1 it is interior
Wall top is fixedly installed with thread groove 101, is closely fitted in the middle part of the outer wall of shell 1 close in the middle part of the inner wall of snap ring 2, shell 1
It is fitted with and stops plate 3, stop and be connected with filtrating smoke dust film layer 4 above plate 3, if the outer wall upper opening of shell 1 is provided with
The top insertion of dry aperture 5, shell 1 is provided with filtering table 6, and the outer wall of filtering table 6 is fixedly installed with screw thread layer 601, filtering
The upper and lower ends of 6 inner wall of disk, which are embedded in, is provided with sieve 602, and filter pulp layer 603, shell 1 are closely fitted between two sieves 602
Inside front be fixedly installed with link block 7, the top of link block 7 is fixedly installed with gag lever post 8.
Further, stopping plate 3 is that up-small and down-big hollow " rotary table " shape is arranged, and the opening area for stopping 3 top of plate is small
In the surface area of filtrating smoke dust film layer 4, so that filtrating smoke dust film layer 4 can be covered on the opening for stopping plate 3, to the air-flow of sucking
Carry out secondary filter.
Further, filtrating smoke dust film layer 4 is agreed with 3 phase of plate is stopped, and filtrating smoke dust film layer 4 is detachably replaced, so that
Filtrating smoke dust film layer 4 can remove the dust in flue gas to the air-flow progress secondary filter of sucking by stopping the support of plate 3.
Further, the other end of aperture 5 runs through the top for being arranged in and stopping plate 3, and filtrating smoke dust film layer 4 is covered on resistance
When 3 surface of sideboard, the outside of filtrating smoke dust film layer 4 is just covered aperture 5, and when user is when exhaling, air-flow blows resistance
The filtrating smoke dust film layer 4 of 3 top of sideboard up extends, so that the outside of filtrating smoke dust film layer 4 no longer covers aperture 5, so that by
The air-flow that filtrating smoke dust film layer 4 is stopped can be discharged from aperture 5, to reduce the respiratory resistance of device when in use.
Further, snap ring 2 is that up big and down small hollow " rotary table " shape is arranged, and snap ring 2 is natural emulsion snap ring 2, so that
When device is embedded in nostril, the lesser part in 2 front end of snap ring is blocked into nasal cavity biggish inside nostril, and 2 end of snap ring
Biggish part is tightly attached to nostril outermost, and since nostril is smaller than nasal cavity, so that user is in breathing, snap ring 2 passes through nose
The support in hole, it is not easy to be blown out and fall off in breathing.
Further, filtering table 6 agrees with 1 phase of shell, and the screw thread layer 601 of filtering table 6 is in the thread groove 101 of shell 1
Mating setting is extracted so that filtering table 6 can be caught within the case 1 or from shell 1 by screw thread layer 601, is easily facilitated pair
Filtrating smoke dust film layer 4 inside shell 1 is replaced and cleaned.
Further, sieve 602 and the inside of filtering table 6 are mutually agreed with, and the outside of sieve 602 is closely fitted with sealing
Item, and sieve 602 is detachable, when so that sieve 602 being entrapped in filtering table 6 by sealing strip, sieve 602 is more difficult de-
It falls.
Working principle: in nasal obstruction smoke filter a kind of using the utility model, device is sequentially embedded to nose first
Kong Zhong, at this moment the lesser part in 2 front end of snap ring is blocked into nasal cavity biggish inside nostril, and the biggish part in 2 end of snap ring
It is tightly attached to nostril outermost, since nostril is smaller than nasal cavity, so that user, in breathing, snap ring 2 is by the support in nostril, no
It is easy to be blown out in breathing and fall off, in breathing, the filtering of gas filter cotton layer 603 logical first enters back into filtrating smoke dust film
Secondary filter is carried out in layer 4, is entered back into nasal cavity, at this moment filtrating smoke dust film layer 4 stops on plate 3 since air-flow drive is tightly attached to
Side, when user is when exhaling, air-flow blows the filtrating smoke dust film layer 4 stopped above plate 3 and up extends, so that filtrating smoke dust film
The outside of layer 4 no longer covers aperture 5, so that can be discharged from aperture 5 by the air-flow that filtrating smoke dust film layer 4 is stopped, to subtract
The respiratory resistance of device when in use is lacked, aperture 5 is plugged again when air-breathing, when needing cleaning replacement filtrating smoke dust film layer
4 with filter pulp layer 603 when, by extracting the sieve 602 in filtering table 6 from filtering table 6, so as to in filtering table 6
Filter pulp layer 603 is replaced and cleaned, by rotating filtering table 6, the thread groove 101 of the screw thread layer 601 of filtering table 6 within the case 1
Middle rotation, so that filtering table 6 can be stretched out from shell 1, it is clear so as to replace to the filtrating smoke dust film layer 4 inside shell 1
It washes, to improve the practicability of device.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
