41 are integrally formed with slideway 411, easy to process.
Technical solutions of the utility model are rotationally connected with cover by using the filter frame 4 of construction mask 100
2, to turn off or open the opening 22 on cover 2, filter frame 4 is then closed when the mask use, so that the mask can be with
Normal use；And when take the mask needs drink water or receive calls when, then filter frame 4 can be directly opened, by cover 2
Opening 22 drunk water or received calls, without the mask is won, convenient and strong applicability.
Further, filter frame 4 is respectively equipped with multiple slots 41 in thickness direction, and the two lateral walls of slot 41, which have, to be slided
Road 411；And cover 2 further includes multiple filtration cores 21, the opposite sides of filtration core 21 has draw runner 211, and filtration core 21 passes through cunning
Item 211 and being slidably matched for slideway 411 are inserted into slot 41.Therefore, the mask can by the filtration core 21 in filter frame 4 come
Air is purified, a large amount of dust of air construction environment and radon daughter is avoided to enter human lung, and draw runner 211 and cunning
The setting in road 411 can easily realize replacement, the cleaning of filtration core 21, obtain the construction with the versatility of mask 100
Reinforce.
In an embodiment of the present invention, referring to Figures 1 and 2, cover 2 is set in close to the side of rotation connection filter frame 4
It is equipped with zipper 24, and to be fixedly connected with direction identical as the up and down direction of cover 2 for the zipper 24.In the embodiment, cover 2 also has
Folding part (not shown), specifically, the folding part can carry out telescopic folding as accordion bellows structure, and folding part is by receiving
Contracting is lockked after folding by zipper 24.When using the construction mask 100, the biggish wearer of shape of face can unzip
24, and the partially folded portion for the cover 2 that extends, so that whole become larger of cover 2 adapts to the shape of face of oneself；And the lesser wearer of shape of face
Then behind the shrinkable folding part, 24 are zipped up to adapt to oneself shape of face size.Therefore, construction mask 100 is gone back
The versatility of the mask can be further increased to adjust the size of cover 2 according to the shape of face size of different wearers.
In the utility model embodiment, referring to Fig.1, filter frame 4 also has buckle far from the side of rotation connection cover 2
42, cover 2 is corresponding to have button hole 23, so that filter frame 4 can be bonded fixation with cover 2 after closing opening 22.The buckle 42 and button
The material in hole 23 is polypropylene, and buckle 42 can be integrally formed with filter frame 4 when processing, and button hole 23 is integrally machined with cover 2, is had
When body is implemented, buckle 42 is arranged two respectively at upper and lower vertical direction with button hole 23, and two buckles 42 are respectively close to filter frame 4
Lower edges, when filter frame 4 close opening 22 after can preferably close opening 22 edges.
In the embodiment, the periphery of filter frame 4 has gasket 43, when filter frame 4 covers the opening 22, gasket
43 abut cover 2, and wherein gasket 43 can be rubber or the gasket 43 of silica gel, by being bonded and fixed to filter frame 4
Periphery.Behind the capping of filter frame 4 opening 22, gasket 43 can block the gap between filter frame 4 and cover 2, improve this and build
The whole air-tightness of construction mask 100 is built, extraneous dust and radon daughter are not easy to touch human body.In another embodiment
In, cover 2 is provided with hydrogel (not shown) towards the side periphery of human face, and when wearing the mask, hydrogel can be with
Prevent outside air from entering through the gap of the mask and human face, and it is filtered and suck lung.
In one embodiment, referring to Fig. 4, filtration core 21 is equipped with lifting ear 212, lifting ear 212 far from groove bottom wall one end of slot 41
Profile semicircular in shape is connected to one end of filtration core 21, can be specifically connected by bonding way.When need by filtration core 21 from insert
When taking-up is replaced or cleaned in slot 41, filtration core 21 can be extracted out of slideway 411 by the lifting ear 212, so that
The disassembly of filtration core 21 and easier for installation.
During the utility model is implemented, referring to Fig. 3, filter frame 4 offers multiple ventilations for running through filter frame 4 in thickness direction
Hole 44, in the embodiment, the quantity of slot 41 and filtration core 21 is 3, and a filtration core 21 correspondence is slidably connected to a slot 41
It is interior.Therefore, venthole 44 extends through filter frame 4 and slot 41 in the side wall of thickness direction, and venthole 44 can guarantee to use and be somebody's turn to do
When construction mask 100, air disengaging is smooth, will not generate sense of discomfort.
Certainly, the quantity of slot 41 can according to need the different filtration cores 21 used and change accordingly, in an embodiment,
The quantity of slot 41 is 1, then venthole 44 runs through the two sidewalls in thickness direction of filter frame 4 accordingly, it is possible to understand that ground,
When slot 41 quantity be it is multiple, such as 3,4 and it is more when, venthole 44 then accordingly run through all slots 41 side
Wall.
Further, the diameter of venthole 44 is 1mm~5mm, and the chamfered shape of venthole 44 is circle, it is preferable that
44 diameter of venthole is 2mm, 3mm, and the venthole 44 of the diameter dimension can guarantee that human body is exchanged with the normal of outside air, together
When can also to avoid construction field in be greater than 44 size of venthole dust particles enter in filter frame 4, thus to mistake
Filter core 21 blocks.
In an embodiment of the present invention, referring to Fig. 5,3 filtration cores 21 are successively arranged in the thickness direction of filter frame 4 is
Active carbon filtration core 21a, aerosil filtration core 21b and hygroscopic fabric filtration core 21c.Wherein, active carbon filters
Core 21a can be the active carbon particle of two layers of polypropylene fibre melt spraying non-woven fabrics package, and with a thickness of 10mm~20mm, active carbon filtration core 21 can
Effectively to adsorb the dust impurities in construction place, the sucking intracorporal air of people is made to obtain matter and purification.And silica
Aeroge filtration core 21b is the fiber reinforced nano silica Aerogel paper of CT100-PET, since aerosil has
There is three-dimensional netted nanostructure, porosity is up to 99.8%, and hole typical sizes are 1nm~100nm, therefore Radon is sub
Body can effectively be adsorbed in aerosil filtration core 21, further purify air and play heat-insulated protection simultaneously and breathe freely and make
With.
In the embodiment, hygroscopic fabric filtration core 21c is cotton fiber and viscose fiber intertexture, hygroscopic fabric filtration core
21c is interweaved by the two, with a thickness of 5mm~10mm, can quickly absorb in air and wearer breathes generation
Moisture avoids the construction mask 100 from so that wearer is generated discomfort due to excessively moist.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes
It changes, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
