Description
Technical field
The utility model relates to the technical field of mask, specially a kind of dust-proof ABS plane cover.
Background technique
With the pollution of environment, also worse and worse, therefore more and more people can carry mask to air quality when outgoing,
And mask refers generally to be worn over nose and mouth for filtering the air for entering mouth and nose, to reach the gas, smell, droplet of blocking harmful
The apparatus for passing in and out wearer's mouth and nose, is made with gauze or paper etc., and mask has certain filtration to the air for entering lung,
When respiratory infectious disease prevalence, in the environment of the pollutions such as dust when operation, mask with extraordinary effect, but at present
Mask be generally just made of gauze, lead to poor filtration effect, just there is the double-deck mask, place replaceable filtering internal
Net, but since filter screen is thrown away using outer needs, cause waste serious, and dust-proof effect is poor, and current mask can not change
Become larger small size, it is therefore desirable to improve.
Summary of the invention
The purpose of this utility model is to provide a kind of dust-proof ABS plane covers, to solve mistake mentioned above in the background art
The problem of strainer can not be recycled, and improve dust-proof effect, and can not change size.
To achieve the above object, the utility model provides the following technical solutions: a kind of dust-proof ABS plane cover, including facial shape
The ABS plastic frame of shape, set on ABS plastic frame side the first breathable gas mask and be set to the ABS plastic frame other side and to ABS plastic
Frame carries out the second breathable gas mask of bound edge processing, and the two sides of the ABS plastic frame are equipped with the flexible fastening rope with hanging hole, the extension
Hole is equipped with the first filter screen, in the first breathable gas mask appearance for tangling ear between the second breathable gas mask and ABS plastic frame
The surrounding up and down in face is equipped with one piece of first flannelette, is equipped with the of one article of arc in the lower section of the first breathable gas mask outer surface
Two flannelettes, and first flannelette and the second flannelette be towards face, detachable is combined with the on the flannelette of the first breathable gas mask
Three breathable gas masks, the one side of the third breathable gas mask are equipped with the filtering string bag, and two sides are relative to mistake above third breathable gas mask
The coplanar position of strainer pocket is respectively equipped with the first hook side of one with the cooperation of the first flannelette, is equipped with and second in the lower section of the filtering string bag
Second hook side of flannelette cooperation, is placed with the filter bag with opening in the filtering string bag, and the opening of the filter bag is equipped with both sides
Sealing cover with baffle, sealing cover are equipped with third flannelette, and the third hook side cooperated with third flannelette is equipped on filter bag,
It has been detachably connected with bridge of the nose cover above ABS plastic frame, more than two buttons have been equipped on ABS plastic frame, on bridge of the nose cover
Two steel-wire carcass for fixing the bridge of the nose are equipped with equipped with the hole location cooperated with button, in the bridge of the nose cover, above bridge of the nose cover
Equipped with bracket, it is equipped with the transparent plastic eyeshade that can adjust spacing in the two sides of bracket, in the outside of transparent plastic eyeshade
Equipped with elastic webbing.
The two sides of the bracket are equipped with the locating rack of internal the first rack gear of band up and down, the side of each transparent plastic eyeshade
Equipped with the slide bar cooperated with corresponding locating rack, upper and lower in slide bar is equipped with and the second rack gear of corresponding first rack gear cooperation.
When work, when needing this mask as common mask in use, can be without using third breathable gas mask, directly general
Face is worn on using ABS plastic frame, is suspended on ear using the hanging hole on flexible fastening rope, then in order to improve fixed effect
Fruit is pinioned using the rope at two-side elastic fixed rope rear portion, utilizes the second breathable gas mask, the first breathable gas mask at this time
The simple filtration to dust is realized with the first filter screen, and when needing using eyeshade, using the cooperation of button and hole location, nose is installed
Then beam cover is clutched according to the mutual two sides of width of the bridge of the nose using internal two steel-wire carcass, bridge of the nose cover is fixed on the bridge of the nose,
Then the spacing for passing through user's glasses, pulls the transparent plastic eyeshade of two sides, the transparent plastic eyeshade of two sides is made to cover glasses,
And fixation is tightened using the elastic webbing of two sides, when using mask at this time, the first breathable gas mask reveals towards face, the second breathable gas mask
Outside out, towards air, while when mask lower part is not big enough, by the first hook side of two sides above spare third breathable gas mask
Cooperate with the first breathable gas mask towards the first flannelette at left and right sides of the lower section of face, realizes that the lower part of mask extends out, because
This can change mask lower part size according to user's demand can be by third breathable gas mask when needing to improve filter effect
First hook side of top two sides cooperates with the first breathable gas mask towards the first flannelette at left and right sides of the top of face, and utilizes
Second flannelette and the second hook side cooperate, and third breathable gas mask is fixed on the second breathable gas mask by realization, third when then using
Breathable gas mask opens simultaneously the opening of filter bag, active carbon powder is put into filter bag, and cover sealing cover towards face,
Filter bag is put into the filtering string bag of third breathable gas mask, in use, air is introduced into the second breathable gas mask subsequently into
One filter screen is once filtered, the first breathable gas mask, is entered back into the filtering string bag after carrying out secondary filter using active carbon, is worn
It crosses third breathable gas mask and enters oral cavity, finally improve filter effect, and after long-time use, take out filter bag, change active carbon
, can also use other filtering materials, be ultimately convenient for using, realize filtering material Reusability, improve using effect, because
This this structure realizes filter screen Reusability, finally improves dust-proof effect, and can change mask lower part size according to size
Effect.
In order to play suggesting effect, it is adhesive with noctilucence lamp bar on the outside both sides of the second breathable gas mask, is designed using lamp bar,
So that illumination suggesting effect can be played when night use.
For the ease of adjusting hanging hole size, a fixing clamp for changing hanging hole size is respectively equipped on two hanging holes
Tool, simultaneously be easy to use, be arranged fixture, allow it different crowd can be suitble to use, can according to the big minor adjustment hanging hole size of ear,
It is clipped on corresponding hanging hole using stationary fixture, changes hanging hole size.
In order to improve filter effect, it is ventilative greater than second that size is combined in the lower section side zip mode of the second breathable gas mask
Air-locked extension of mask, the two sides of the extension are respectively equipped with hanging strip, are fixed in third breathable gas mask and mistake
When work, when needing also to block lower face, extension is installed using the structure of zipper for the snorkel of strainer pocket perforation
Onto the second breathable gas mask, then it is fixed on neck using the hanging strip of two sides, while when needing to improve filter effect,
Extension is installed on the second breathable gas mask using the structure of zipper at this time, extension is then turned to top, covers the
Then two breathable gas masks are mutually held tightly around head using the hanging strip of two sides, are blocked the air intake of the second breathable gas mask with this,
Air-breathing and exhaust are by snorkel disengaging at this time, and when air inlet, air is directly entered filter screen, utilizes the active carbon mistake in filter screen
Filter, so that gas improves filter effect, oral cavity of then entering finally better can cross air filtering all by filter screen filtration
In impurity and dust and pernicious gas.
