Description

A kind of protective mask with filtering function

Technical field

The utility model is related to arrive a kind of protective articles more particularly to a kind of good permeability and reusable have The protective mask of filtering function.

Background technology

Mask is easy to use with its, of low cost and be used widely as a kind of protective articles, in order to increase protection Effect is generally overlapped using multilayer cotton gauze or carries filter secretly in multilayer cotton gauze to enhance filter effect, therefore caused The permeability degradation of mask, causes comfort poor, and since pollutant fine grained is persistently embedded in cotton gauze Or in the micropore of filter and gather, it is difficult to remove, keep the service life of mask shorter, be typically only capable to disposable, increase Use cost.

Utility model content

The utility model mainly solves that existing common protective mask gas permeability is poor, the technical issues of cannot reusing； Provide a kind of good permeability and the reusable protective mask with filtering function.

In order to solve above-mentioned technical problem, the utility model mainly uses following technical proposals：

A kind of protective mask with filtering function of the utility model, the protective mask include and face face kissing The cover and ear band of conjunction, the cover center have been sequentially distributed air inlet area corresponding with mouth and nose position and outlet area, it is described into Gas area is equipped with multiple air admission holes, and the outlet area is equipped with multiple ventholes, cover inner central be equipped with cover above-mentioned air inlet area and Separable protector is arranged in the protector in outlet area on the cover of mask, can replace filtering body or clear in time as needed Protector is washed, protection quality and usage comfort is effectively increased, reduces use cost.

Preferably, the protector includes pedestal, the pedestal is connected in the inner central of the cover, pedestal lower part Equipped with exhaling hole corresponding with the outlet area, the middle of the base is equipped with groove corresponding with the air inlet area, the groove For opening towards outside, groove floor is equipped with suction hole corresponding with face nose, be embedded in groove match with groove and The filtering body of entire suction hole is covered, protector opens up meter using snoot, and filter replaceable in the setting of nose intake region The smaller filtering body of resistance is as protective layer so that filter effect and comfort is more preferable, use cost is relatively low.

Preferably, the filtering body is in collapsible structure of filtering layer, grenadine, nose suction zone are covered on the exhaling hole The filtering body in domain is designed in collapsible structure of filtering layer, and filter area is expanded in limited volume, is improved gas permeability and is relaxed Adaptive, and the grenadine in oral area expiration region designs, then reduces expiratory resistance.

Preferably, being additionally provided with the silica gel for enclosing base edge and being bonded with face face on the inside edge of the pedestal Circle, soft silica gel ring are fitted in facial surroundings, have completely cut off the infiltration of extraneous air, improve seal and the protection of mask Property, also improve the comfort of mask.

The utility model has the beneficial effects that：Separable protector is set on the cover of mask, and uses snout In nose intake region replaceable and smaller filtration resistance collapsible filtering layer is arranged as protective layer in zoning design, can be as needed Filtering body or cleaning protector are replaced in time so that filter effect and comfort are more preferable, and use cost is lower.

1. cover in figure, 2. ear bands, 3. air admission holes, 4. ventholes, 5. pedestals, 6. exhaling holes, 7. grooves, 8. suction holes, 9. filtering body, 10. silica gel rings.

Specific implementation mode

Below with reference to the embodiments and with reference to the accompanying drawing being further described in detail to technical solutions of the utility model.

Embodiment：A kind of protective mask with filtering function of the present embodiment, as shown in Figure 1, Figure 2 and Figure 3, including with The cover 1 and ear band 2 that face face matches, cover center have been sequentially distributed air inlet area corresponding with mouth and nose position and outlet Area, air inlet area are designed with multiple air admission holes 3, and outlet area is designed with multiple ventholes 4, and it is above-mentioned that cover inner central is equipped with covering The protector of air inlet area and outlet area, protector include pedestal 5, and pedestal is connected in the inner central of cover, the design of pedestal lower part There is exhaling hole 6 corresponding with above-mentioned outlet area, grenadine is covered on exhaling hole, the middle of the base is designed with and above-mentioned air inlet area phase Corresponding groove 7, slot opening is towards outside and covers entire air admission hole, and groove floor is designed with corresponding with face nose Suction hole 8, the filtering body 9 that entire suction hole is matched and covered with groove is embedded in groove, and filtering body is in collapsible filtering layer Structure is also devised with the silica gel ring 10 for enclosing base edge and being bonded with face face in the inside edge of pedestal.

In use, mask is covered face face, soft silica gel ring is fitted in the surrounding of face, keeps fitting comfortable and close It closes, at this point, sucking nasal cavity after filtering of the extraneous air by the collapsible filtering layer on protector, filter area is big, resistance is small, no It may feel that sulks, protect good filtration effect, and exhale and be then discharged by grenadine, expiratory resistance is also smaller, and mask is made to use Comfort is preferable, when mask usage time is longer or feels inspiratory dyspnea, it may be possible to which dust granules plug the filter of filtering body Hole under can then dialling protector, takes out the filtering body in groove and cleans grenadine, then be reinstalled new filtering body, mask is again It can restore, as new, without abandoning entire mask, only to replace corresponding component, use cost is relatively low.

Technical term "upper", "lower", "front", "rear", "left", "right", "inner", "outside" in the description of the present invention, It is direction based on ... shown in the drawings or position relationship Deng expression direction or position relationship, is merely for convenience of describing and understanding this reality With novel technical solution, described above not to limit the utility model, those of ordinary skill in the art are in this practicality The interior variation made of novel essential scope is retrofited, increases or is replaced, and the scope of protection of the utility model is regarded as.
