Description

A kind of removable haze mouth mask

Technical field

The utility model relates to a kind of mouth mask, specifically refers to a kind of removable haze mouth mask.

Background technology

In recent years, due to industrialization and urbanization sharply, cause the energy rapidly to consume, densely-populated, environmental destruction, there is long haze weather in China's central and east most area, larger harm is produced to human respiratory and cardiovascular system, the healthy formation of people is threatened.The haze mouth mask of going out to wear specialty effectively can reduce the injury that haze brings.

In China Chemical Industry net, " PM2.5 mouth mask allows of no optimist, GB is expected to put into effect next year " to claim, in market, the mouth mask protection effect of nearly seventy percent is not good, in 162 kinds of mouth masks of test, find that filter effect accounts for 13.58% more than 90%, filter effect be less than 50% account for 69.75%.Traditional air filting material comprises the woven filter screen of plastics, glassfibre filters, synthetic fibers filter screen, but the cost of manufacture of these materials is high, and preparation process bothers, ventilative rate variance.Chinese patent CN104621783A (publication date 20150520) discloses and to ensure respiration environmental amenity degree by increasing fold, but the cover body that this mouth mask adopts is the medical mask of 12 layers, this cover body can not be fitted human body face completely, gas can enter from gap, and filter effect can be affected.Micropore ceramics is a kind of new material, there is the advantages such as high porosity, pore size is controlled, bulk density is little, specific area is large, to gas and liquid, there is selective penetrated property, there is physical absorption and chemisorbed double action, high temperature resistant, corrosion-resistant, stable chemical nature, preparation process is convenient, the advantages such as preparation cost is low.

Summary of the invention

The purpose of this utility model proposes a kind of removable haze mouth mask, this mouth mask is that employing mixing condensation product makes mouth mask cover body (as silica gel), uses non-woven fabrics, activated carbon filter layer and micropore ceramic filter layer multi-layer filter disc as filter course, effectively can stop the suction of the particle such as dust, PM10, PM2.5.

The technical scheme that the utility model is taked is as follows:

A kind of removable haze mouth mask, comprise the mixture cover body can fitted with human body face in edge, mixture cover body both sides are provided with elastic cord, mixture cover body is provided with vent valve, vent valve is ventilative box-like, and has openable lid, is built-in with filter course, described filter course comprises stacked activated carbon filter layer and micropore ceramic filter layer, outside filter course, be also enclosed with non-woven fabrics.

Mixture cover body can be fitted completely with human body face, can prevent air from entering from side, ensures that gas can only be entered by vent valve.

Filter course is inner at vent valve, and vent valve can be opened, and can change filter course.

Mouth mask can adopt 3 D stereo to design, and for providing good cavity around nose and oral cavity, can improve the comfort level of mouth mask.

During use, first vent valve is opened, filter course is put into vent valve, then elastic cord is fixed on ear, ensure to fit preferably with face while adjustment degree of tightness.This mouth mask cover body is made by mixing condensation product, as adopted the materials such as silica gel, and soft conformable face, good airproof performance, capable of washing, by arranging the filter course of removable and replaceable, the repeatedly utilization of mouth mask can be realized.

The utility model has following beneficial effect: haze Respirator structure of the present utility model is simple, cost is low, comfort level is high, good air purification effect, can effectively prevent the suction of the deleterious particle such as dust, PM10, PM2.5, product volume little, be convenient for carrying.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, a kind of removable haze mouth mask, its structure comprises silica gel cover body 1, two vent valves 2, filter course 3 and elastic cords 4; The both sides of silica gel cover body are located at by elastic cord, and two vent valves 2 are embedded in silica gel cover body 1 respectively; It is inner that filter course 3 is located at vent valve 2.

Filter course 3 is multiple filtration system, comprises stacked activated carbon filter layer a and micropore ceramic filter layer b, and outside non-woven fabrics c wraps up.

Wherein, vent valve 2 is box-like for what breathe freely, has openable lid, is convenient to change inner filter course 3.

During use, first vent valve 2 is opened, filter course 3 is put into vent valve, then coordinate elastic cord 4 to be fixed by mouth mask, ensure to fit preferably with face while adjustment degree of tightness.

More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand, the utility model is not restricted to the described embodiments, what above-described embodiment and description described just illustrates principle of the present utility model, under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all will fall in scope of the present utility model.
