Embodiment
In order that those skilled in the art more fully understands technical scheme, below in conjunction with accompanying drawing to this hair
It is bright to be further detailed.
Referring to shown in Fig. 1-3；
A kind of chemical experiment gas mask of multi-filtering layer of the present invention, including：
Mask body 1；Layer assembly is filtered, filtering layer assembly is arranged at the front end of mask body 1, is placed in user's oral area position
Put place；Eyeshade portion 2 is additionally provided with mask body 1, glasses 3 are embedded with eyeshade portion 2；Filtering layer assembly includes being formed as multilayer
The filtering layer standing groove of structure and the filtering layer 14 in every layer of filtering layer standing groove；The filtering layer standing groove of multilayer is by mask master
The front end of body 1 is laid towards the front of mask body 1, and into hierarchy；It is placed in the sectional dimension of the filtering layer standing groove of front end
No more than the sectional dimension for the filtering layer standing groove for being placed in rear end；Wherein, filtering layer 14 is alkaline filter layer and/or acid filter layer
And/or active carbon layer.
Specifically, present embodiment discloses a kind of chemical experiment gas mask with multi-filtering layer, before its mask body
End devises filtering layer component, wherein, the filtering layer component is in sandwich construction, and alkaline mistake can be optionally put into filtering layer component
Filtering layer or acid filter layer or active carbon layer or other desired filter layer, in addition, in order to place the convenient of filter layer, and
The aesthetics of overall appearance, the filtering layer standing groove size that U.S. is regarded in the filtering layer assembly in eyesight is smaller closer to front end, presents
The trend subtracted, the filtering layer standing groove positioned at rear side can will not be so blocked when placing filtering layer 14 is put into operation.
Preferably, the rear end of mask body 1 is fastened on user's formed with concave part, mask body 1 by the concave part
Face；Filtering layer standing groove includes the cell body that upper end opens, and the rear end of cell body opens, and the open end of the rear end of cell body extends back ground
Formed with linking arm 13；The both sides of on the mask body 1 and front end of the cell body of filtering layer standing groove offer connected slot；
Fixed between cell body and mask body 1 and two neighboring mask body 1 by linking arm 13 and connected slot installation；Groove
It is embedded with filtering layer 14 in vivo.For the sealing of entirety and the comfort level of wearing, the present embodiment is spread in the inner ring of mask body 1
If one layer of silicagel pad 9, meanwhile, it is not blocked for the smooth and visual field of breathing, eye of the present embodiment in the silicagel pad 9
And oral area has opened up corresponding opening, it is allowed to be connected with mask body 1, itself and part bedding mask body 1.Go out from structure
Hair, the cell body that one upper end opens during filtering layer standing groove in the present embodiment, due to needing to be embedded in filtering layer 14 in filtering layer standing groove, and
Filtering layer 14 is used as respiration channel, itself and mask body 1, or even whole passage is required for strict sealing, therefore, in order to full
Sufficient seal request, the rear side of cell body is also open architecture, and when being embedded in filtering layer, the thickness of filtering layer 14 needs the groove slightly larger than cell body
Structure, so by interference fit, unnecessary space in cell body can be filled full, allow air only to pass through from filtering layer 14.And
In order to facilitate maintenance, the cell body in the present embodiment employs the type of attachment of clamping, and it can be installed or removed in mask master
On body 1, facilitate the residual particles accumulated in later stage cleaning mask body 1 and cell body by long-time use.
It is furthermore preferred that cell body is in the quadrangle trough body structure with cavity in such scheme, and the upper surface of cell body is installed
There is capping.For the stability and sealing of structure after installation filtering layer 14, gas is avoided to enter device from the top of cell body,
In the upper design capping of cell body, the capping can be clamping installation, can be the form of chute, can also design hasp lock
Etc. form.
Specifically, as the preferable technical scheme of the present embodiment：Filtering layer assembly is double-decker, is respectively close to mask
First filtering layer standing groove 4 of the installation of main body 1 and the second filtering layer standing groove 5 for being placed in the front end of the first filtering layer standing groove 4；First
The cell body of filtering layer standing groove 4 is the first cell body, and the cell body of the second filtering layer standing groove 5 is the second cell body；The section chi of second cell body
The very little sectional dimension for being less than the first cell body, and the second cell body is mounted at the center of the first cell body；Mask body 1 passes through
The opening position of the covering of one cell body is the first passage 10 of the fenestral fabric with through hole, and the front end of the first cell body passes through the
The opening position of the covering of two cell bodies is the second passage 11 of the fenestral fabric with through hole, and the front end face of the second cell body is tool
There is the 3rd passage 12 of the fenestral fabric of through hole；
Wherein, the aperture of the first passage 10 is more than the size of the second passage 11, the second passage 11 in such scheme
Size be more than the 3rd passage 12 size；The capping installed on first cell body is the first capping, is installed on the second cell body
Cover as the second capping.
Described in such scheme in order to which whole structure is more attractive, and will not hinder and be filtered in the filtering layer standing groove of side rearward
Layer 14 is put into operation, and the size of the cell body of the present embodiment second needs the size for being less than the first cell body, and for good filtration effect,
Avoid bulky grain suspended material from entering filtering layer 14, and there are enough air circulations at breathing, in the present embodiment from the inside to the outside
The size of passage is sequentially reduced.
Preferably, in the present embodiment the second filtering layer standing groove 5 be two, two the second filtering layer standing grooves 5 be arranged side by side in
The front end of first filtering layer standing groove 4；And two the second filtering layer standing grooves 5 are integral type structure.In addition, in the second filtering layer standing groove
Be horizontally arranged with a plurality of gauze standing groove 8 of 5 front end along the second filtering layer standing groove 5, is embedded with each gauze standing groove 8
Gauze.Gauze can be with absorbed portion suspension, and two the second filtering layer standing grooves 5 are to be able to selectively place needs
Filtering layer 14.Meanwhile in order to which filter effect is more preferable, warp layer cloth is compounded with each filtering layer 14.
In the above-mentioned technical solutions, the chemical experiment gas mask of a kind of multi-filtering layer provided by the invention, passes through compound peace
Multilayer filtering layer standing groove is sequentially overlapped by the filtering layer assembly of dress, is independently selected to be inlaid in filtering layer standing groove according to experimental situation
Filtering layer 14 value volume and range of product, it is simple to operate, it is practical.
Some one exemplary embodiments of the present invention are only described by way of explanation above, undoubtedly, for ability
The those of ordinary skill in domain, without departing from the spirit and scope of the present invention, can be with a variety of modes to institute
The embodiment of description is modified.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as to the present invention
The limitation of claims.
