Abstract

This is practical newly relates to a kind of nano protective mask, comprise mask main body, be set on ear that mask main body bilateral symmetry the arranges ear band in holes, and be arranged on the breather valve of mask main body outer surface, it is characterized in that: described mask main body is made up of outer nonwoven layer, active carbon filtering layer, nanofiltration membrane layer, acupuncture cotton and interior nonwoven from outside to inside successively.

Description

A kind of nano protective mask

Technical field

The utility model relates to a kind of protective mask, especially relates to a kind of protective mask that adopts nanometer filtering layer technology.

Background technology

Along with air-polluting continues being on the increase of aggravation and haze weather, mouth mask has become the necessary article that people go out gradually.But the PM2.5 protective mask market of current China meets with counterfeit dual problem prevailing and that standard is fuzzy and is converging.On the one hand, the restriction of industry access threshold does not promote with the expansion of market scale, has occurred the situation that mountain vallage mouth mask floods market; On the other hand, because PM2.5 mouth mask market belongs to emerging market, not yet set up sound market order, the national standard of industry is put into effect so far not yet, causes industrial mouth mask to be misapplied by a large amount of consumers, has huge healthy hidden danger.There are the following problems for common PM2.5 protective mask product at present: 1) security protection consciousness is poor, and 60 percent crowd pays close attention to low to haze and viral harm; To PM2.5, PM1.0, PM0.3, PM0.1 cognition degree is inadequate; 2) standard is fuzzy, and the domestic standard to face shield is fuzzy, and method of testing limits indefinite, and dragons and fishes jumbled together to cause on market face shield product; 3) technology is without innovation, at present domestic to the research of face shield technology substantially in outward appearance conceptual phase, and little except specialty to the critical component filter film technology of face shield, technological innovation is little; 4) production environment is poor, and mouth mask, as Protection Product, directly contacts with human body, high to production environment requirement, but domestic do not have clear and definite standard to production environment at present.

Utility model content

The purpose of this utility model: be intended to propose a kind of protective mask that adopts nanometer filtering layer technology; the mode that this mouth mask adopts traditional Electrostatic Absorption technology to combine with nanometer technology; in guaranteeing strainability, strengthen the protection to filter membrane structure; make the filter effect of mouth mask better, service life is stronger.

This nano protective mask, comprise mask main body, be set on the ear band of mask main body both sides, and be arranged on the breather valve of mask main body outer surface, it is characterized in that: described mask main body is made up of nonwoven layer, active carbon filtering layer, nanofiltration membrane layer, acupuncture cotton and nonwoven from outside to inside successively.

Described nanofiltration membrane layer is all made up of with the nano fibrous membrane of nonwoven upper and lower surface.

Nanofiltration membrane layer of the present utility model adopts similar sandwich sandwich, effectively protects nano fibrous membrane to go to pot, and guarantees the performance of filter membrane simultaneously.Meanwhile, the mode that the traditional filter membrane of this employing is combined with nanofiber, can effectively filter the above particle of PM0.3 and effectively filter, and also can implement effectively to filter to the following particle of the larger PM0.3 of harm; This simple combination, is different from pure nanofiltration layer technology, mouth mask good permeability, comfortable wearing.

Nonwoven layer 10-nano fibrous membrane 11.1-nonwoven 11.2-nonwoven in the outer nonwoven layer 6-active carbon filtering layer 7-nanofiltration membrane layer 8-acupuncture cotton 9-of 1-ear band 2-ear 3-mask main body with holes 4-breather valve 5-.

Detailed description of the invention

We are described in further detail this nano protective mask with concrete example by reference to the accompanying drawings below, in the hope of more clear its structure and the occupation mode set forth.

This nano protective mask as shown in the figure, comprise mask main body 3, be set on mask main body 3 bilateral symmetry arrange ear with holes 2 in ear band 1, and be arranged on the breather valve 4 of mask main body 3 outer surfaces, it is characterized in that: described mask main body 3 is made up of outer nonwoven layer 5, active carbon filtering layer 6, nanofiltration membrane layer 7, acupuncture cotton 8 and interior nonwoven 9 from outside to inside successively.

Described nanofiltration membrane layer 7 is all made up of with the nano fibrous membrane 10 of nonwoven upper and lower surface.
