Description

Combined type nose outer air purifier

Technical field

The present invention relates to a kind of air cleaning unit, particularly a kind of air purifier for nasal cavity protection.

Background technology

In the situation that air ambient is poor, people adopt the means that wear masks to carry out self-protection conventionally, but the shortcoming existing that wears masks is: because nose is outstanding at face, mouth mask and face and nose have gap around, still have grit and pernicious gas and enter into the gap between mouth mask and face with air-flow, and be drawn in body by nose.Chinese patent discloses some and has been exclusively used in the air purifier of nose, and these clarifiers can be realized the air that nose is sucked and filter, but they substantially all exist again and wear inconvenience, easily come off, protect incomplete shortcoming.

Summary of the invention

The object of the present invention is to provide a kind of combined type nose outer air purifier, this air cleaning unit is worn conveniently, protection is comprehensive.

For achieving the above object, the present invention adopts following scheme: combined type nose outer air purifier, it has the mouth mask consisting of mouth mask body and rope band, mouth mask body inner side is fixed with a bag, a pair of nose outer air clarifier is housed in bag, and the nasal obstruction pipe that nose outer air clarifier has stretches out outside bag.

From such scheme, while using nose outer air purifier provided by the invention, can first the nasal obstruction pipe close of nose outer air clarifier be entered to nostril, again mouth mask is worn, or first mouth mask is worn, the nasal obstruction pipe close of nose outer air clarifier is entered to nostril, nose outer air clarifier is relied on by mouth mask again, guarantees that it can not come off; By nose outer air clarifier, mouth mask, can respectively the air of nose and oral area suction be realized and being filtered.

Useful technique effect of the present invention is: wear convenience, reliable, protection comprehensively.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing, further illustrate the present invention.

Referring to Fig. 1, Fig. 2

Combined type nose outer air purifier provided by the invention, it has the mouth mask consisting of mouth mask body 2 and rope band 1, mouth mask body 2 inner sides are fixed with a bag 3, and the nose outer air clarifier 4 of a pair of symmetry is housed in bag 3, and the nasal obstruction pipe 4a that nose outer air clarifier 4 has stretches out outside bag.

Referring to Fig. 3

Nose outer air clarifier 4 in the present invention comprises filter cup 4g and nasal obstruction pipe 4a, filter cup 4g lower end is uncovered and bowl cover 4e is housed, on bowl cover 4e, have through hole 4f, in filter cup 4g, be provided with filter assemblies, filter assemblies is two-layer or multilayer sponge filtering layer 4c, layer of active carbon filtering layer 4d and two-layer or multilayer sponge (or fiber) the filtering layer 4c1 distributing successively from top to bottom, nasal obstruction pipe 4a is connected with filter cup 4g upside and communicates with its inner chamber, there is bending at nasal obstruction pipe 4a middle part, and flexible sleeve pipe 4b is overlapped on nasal obstruction pipe 4a top.According to varying in size of people's nostril size, the outside dimension of nasal obstruction pipe 4a can have outside different model, also can pass through the configuration of spring-backed quill 4b, and fine-tuning nasal obstruction pipe coordinates with nostril.Above-described nose outer air clarifier and the nose outer air clarifier that Chinese patent is disclosed, the patent No. is 201320355992.0 are structurally basic identical.

Referring to Fig. 4 to 6

The difference of the present embodiment and above-described embodiment one be in nose outer air clarifier bowl cover and nasal obstruction pipe structure, concrete structure is as follows: nose outer air clarifier has filter cup 4g, bowl cover 4e, nasal obstruction pipe 4a and is arranged on the filter assemblies of filter cup 4g inside, bowl cover 4e is by the lower port sealing of filter cup 4g, and nasal obstruction pipe 4a joins with the top of filter cup 4g and communicates with its inside.On bowl cover 4e, be provided with a breather cheek valve 5, the upper position relative with its mouth of pipe of nasal obstruction pipe 4a has through hole 4h, is provided with an one-way exhaust valve 6 in through hole 4h.

Described breather cheek valve 5 has one group of air admission hole 5a and a first film lobe 5b who coordinates and have flexibility with air admission hole who is located on bowl cover 4e, the middle part of the first film lobe 5b mono-side is connected with the inner side of bowl cover 4e, and the first film lobe 5b covers all air admission hole 5a, in the inner side of bowl cover 4e, have the first outstanding back-up ring 5e, the first back-up ring surrounds one group of air admission hole 5a and the first film lobe 5b.Syndeton between the first film lobe 5b mono-side and bowl cover 4e is: the middle part of the first film lobe 5b mono-side has the first outstanding pillar 5c, and the first pillar 5c lower end has outstanding positive stop end 5d, and the first pillar 5c is through bowl cover 4e.

Described one-way exhaust valve 6 has a dividing plate 6e who has a plurality of steam vent 6a, an and second film lobe 6b who coordinates and have flexibility with steam vent, the middle part of the second film lobe 6b mono-side is connected with the outside of dividing plate 6e, and the second film lobe 6b covers all steam vent 6a.Syndeton between the tube wall of the second film lobe 6b mono-side and nasal obstruction pipe 4a is: the middle part of the second film lobe 6b mono-side has the second outstanding pillar 6c, and the second pillar 6c lower end has outstanding positive stop end 6d, and the first pillar 6c is through dividing plate 6e.In addition, dividing plate 6e and through hole 4h are interference fit.

Above-mentioned breather cheek valve 5 is structurally identical with one-way exhaust valve 6.In addition, above-mentioned the first film lobe 5b, the second film lobe 6b can select commercially available soft rubber material.

In the present embodiment, filter assemblies (not illustrating in Fig. 4-Fig. 5) is also housed in filter cup 4g, identical with shown in Fig. 3 of this filter assemblies.In addition, the flexible cushion rubber 7 of the upper cover of nasal obstruction pipe 4a, its effect is identical with the spring-backed quill 4b in Fig. 3.

From Fig. 4, Fig. 5, nasal obstruction pipe 4a is filled in human nasal, when air-breathing, the second film lobe 6b of one-way exhaust valve 6 shelters from all steam vent 6a being close on dividing plate 6e, make one-way exhaust valve 6 in closed condition, meanwhile, there is deformation in the first film lobe 5b of breather cheek valve 5 in the first back-up ring 5e, and air enters in nose outer air clarifier from air admission hole 5a; Otherwise during expiration, the first film lobe 5b of breather cheek valve 5 is close on bowl cover 4e, make breather cheek valve 5 in closed condition, meanwhile, there is deformation in the second film lobe 6b of one-way exhaust valve 6 in the second back-up ring 6e, and air is from steam vent 6a flows out nose outer air clarifier.In gas due to nose exhalation, contain more moisture, in the filter assemblies of moisture entrapment in filter cup 4g, can affect filter effect, the gas major part that the present embodiment can make nose breathe out is discharged by one-way exhaust valve, greatly reduced residual in filter assemblies of moisture, and then filter effect is guaranteed.

In the present invention, abundant filtration due to mouth mask body and nose outer air clarifier, effective filtering fine particle (PM2.5), meanwhile, the active carbon filtering layer of the enough volumes in nose outer air clarifier can adsorb airborne pernicious gas fall (as the pernicious gas in haze and suspension) again.
