A kind of double-type mouth maskTechnical field
The present invention relates to mouth mask technical field, be specifically related to a kind of double-type mouth mask.
Background technology
Mouth mask effectively can prevent breathing problem, avoids extraneous haze and various bacterium to the intrusion of human body.In recent years, along with haze occurs on a large scale all over China, the requirement of people to mouth mask is also more and more higher.
Mouth mask common on existing market, as the N95 level mouth mask of 3M company, although can prevent PM2.5 particulate, because filterability only has 95%, wears and still can smell 5% stink into lavatory, and when mouth mask normally works and user's face paste very tight, very uncomfortable.
Chinese patent, a kind of rhinobyon type mouth mask filterability reaches 99.9%, but breathes comfortable not.
Therefore, be badly in need of at present a kind of cost low, comfortable, filterability reaches 97%, not only can anti-PM2.5 particulate, can also the mouth mask of anti-odour.
Summary of the invention
Embodiments provide double-type mouth mask and reach high filtration rate problem to solve low cost mouth mask.
An object of the present invention is, provides a kind of filterability to reach the low cost mouth mask of 97%.
A kind of double-type mouth mask, comprising: mask body, bilateral semicircle elastic rod, the second filter cloth.
Mask body is made up of filter cloth, mouth mask frenulum, on the nose that four limits are fitted in people and face.
Bilateral semicircle elastic rod is arranged on position corresponding to mask body medial surface nostril, and from bottom to top, elastic rod limit is connected with inside mask body, round two nostrils in the middle of elastic rod.
Second filter cloth is arranged on bilateral semicircle elastic rod, produces pressure by elastic rod, makes the second filter cloth be close to nostril all the time.
The top of bilateral semicircle elastic rod forms by two layers, and centre can sandwich the second filter cloth, can sandwich the thickest second filter cloth between 1 millimeter to 10 millimeters, and following individual layer composition, walks around for mending the second filter cloth.
Second filter cloth is made up of anti-particulate layer, antibiotic layer, activated carbon paper, non-woven fabrics.
Second filter cloth shape is mated with bilateral semicircle elastic rod, and two nostril correspondence positions are thick, and limit is gradually thin.
The second the thickest position of filter cloth is between 1 millimeter to 10 millimeters.
Second filter cloth edge is than inner high, and height is identical with the thickness of the top of limit semicircle elastic rod.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those skilled in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of double-type mouth mask of embodiment of the present invention schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of double-type mouth mask, comprising: mask body, bilateral semicircle elastic rod, the second filter cloth.
Mask body is made up of filter cloth, mouth mask frenulum, on the nose that four limits are fitted in people and face.
Bilateral semicircle elastic rod is arranged on position corresponding to mask body medial surface nostril, and from bottom to top, elastic rod limit is connected with inside mask body, round two nostrils in the middle of elastic rod.
Second filter cloth is arranged on bilateral semicircle elastic rod, produces pressure by elastic rod, makes the second filter cloth be close to nostril all the time.
The top of bilateral semicircle elastic rod forms by two layers, and centre can sandwich the second filter cloth, can sandwich the thickest second filter cloth between 1 millimeter to 10 millimeters, and following individual layer composition, walks around for mending the second filter cloth.
Second filter cloth is made up of anti-particulate layer, antibiotic layer, activated carbon paper, non-woven fabrics.
Second filter cloth shape is mated with bilateral semicircle elastic rod, and two nostril correspondence positions are thick, and limit is gradually thin.
The second the thickest position of filter cloth is between 1 millimeter to 10 millimeters.
Second filter cloth edge is than inner high, and height is identical with the thickness of the top of limit semicircle elastic rod.
Apply specific embodiment in the present invention to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
