Description

A kind of Novel anti-mist haze mask

Technical field

This utility model relates to protective articles field, especially a kind of Novel anti-mist haze mask.

Background technology

Medical circle is thought, the granule that particle diameter is more than 10 microns can be blocked in outside the nose of people；Particle diameter 2.5-10 The particulate matter of micron can enter respiratory tract, and part is discharged by sputum；And particle diameter is at 2.5 microns and less Particulate matter is difficult to be blocked, and can enter bronchus, alveolar even blood circulation, causes asthma, a gas Guan Yan, emphysema and cardiovascular, reproductive system disease.Affected area by haze weather in recent years and accounted for territory Area 1/4, mainly based on a wide line city of waiting of going up north, especially occurs the most serious in North China Severe haze, impacted about 600,000,000 people, cause serious threat to health.

For the maximally effective safeguard procedures of haze weather, one is to reduce to go out the time, stops outdoor activity as far as possible； Two wear anti-haze protector when being to go out.Optimal mask not only possesses efficient filter effect, in addition it is also necessary to tool Standby less respiratory resistance；Secondly, good sealing effect high with human body face laminating degree is needed.On material also Should possess feature nontoxic, tasteless, free from corrosion.The kind of mask has: cotton mask, non-woven fabrics gauze mask, Macromolecular material mask, activated carbon powder filter element mask, NACF felt pan mask etc..It is divided into from style: Flat, cup type, collapsible (freshwater mussel type and walk) three major types.

But, mask generally exists that filter efficiency is low, leaks gas, the shortcoming such as can not reuse the most on the market. The leakage rate of mask is high, and the pattern construction being primarily due to product is unreasonable, under wearing state, mask with Adaptation between wearer's face is bad.According to fluid mechanics principle, flow limitation flows to the little place of resistance, Mask and face closely sealed bad time, air-flow is obstructed filter material directly through gap, can cause PM2.5 granule Thing leaks into or is inhaled into.Especially bridge of the nose position, in winter, breathing out of exhalation can make the user of wearing spectacles Eyeglass on form mist and affect sight line.The general preferable mask of effect is worn rear mask internal layer for a long time and can be accumulated Water droplet, the air of exhalation congeal into water droplet flow to mask with face edge the most uncomfortable.Part design is preferably Professional adverse circumstances mask, wear complex steps, profile seems canister respirator, and this type of mask Price is higher, is difficult to by the people well-established.Above-mentioned mask is commonly once in addition to specialty adverse circumstances mask Property mask, mask utilization rate is low.

Utility model content

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, it is provided that a kind of Novel anti-mist haze mouth Cover.It is placed through hole by arranging filter disc and prevents filter from carrying out sucking air mistake in filter disc places through hole Filter prevents haze from impacting health, changes filter mask and can be recycled, improves mask utilization rate, By arranging sealing strip on edge, cover body surrounding, when preventing from wearing, face and mask laminating imprecision, cause Gas leak phenomenon, by arranging the discharge of breathing out by exhalation of the one-way air flowing valve, prevents condensing water droplet or water smoke Generation.

For achieving the above object, this utility model employing following technical proposals: a kind of Novel anti-mist haze mask, It includes that cover body, described cover body top have the groove that applicable bridge of the nose card is put, described cover body offer multiple Filter disc places through hole, and each described filter disc is equipped with the fixing lid of filter disc in placing through hole, each described filter disc is put Have in putting through hole and fix the filter that lid is fixed in filter disc placement through hole, a left side for described cover body by filter disc Right two ends are each provided with a regulation frenulum, and described cover body is additionally provided with one-way air flowing valve, described cover The outboard cover of body is equipped with cover layer, and described cover body surrounding is along being provided with sealing strip.

Preferably, multiple described filter discs place through hole is the circular port that diameter does not waits.

Preferably, on described cover body, filter disc places the number of through hole is two.

The beneficial effects of the utility model are:

This utility model is placed through hole by filter disc and prevents filter from carrying out sucking sky in filter disc places through hole Gas filters and prevents haze from impacting health, changes filter mask and can be recycled, and improves mask profit By rate, by cover body surrounding along arranging sealing strip, when preventing from wearing, face and mask are fitted imprecision, Cause gas leak phenomenon, by arrange one-way air flowing valve will exhalation discharge of breathing out, prevent condensing water droplet or The generation of water smoke.

Detailed description of the invention

Needing exist for explanation, the described noun of locality is left and right, upper and lower is all to be with the view shown in Fig. 1 Benchmark definition, it will be appreciated that the use of the described noun of locality should not limit the protection domain that the application is asked.

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

As depicted in figs. 1 and 2, a kind of Novel anti-mist haze mask, it includes cover body 6, described cover body 6 top There is the groove 6-1 that applicable bridge of the nose card is put, described cover body 6 offers multiple filter disc and places through hole 2, each Described filter disc is equipped with filter disc and fixes lid 3 in placing through hole 2, each described filter disc has logical in placing through hole 2 The filter that lid 3 is fixed in filter disc placement through hole 2 fixed by filter, and the two ends, left and right of described cover body 6 are each Equipped with a regulation frenulum 7, described cover body 6 is additionally provided with one-way air flowing valve 4, described cover body 6 Outboard cover equipped with cover layer 5, described cover body 6 surrounding is along being provided with sealing strip 1.

The macromolecular materials such as cover body 6 material selection plastics, rubber, silica gel, filter selection filter fiber, The materials such as activated carbon, filter disc fixing lid 3 selection plastics or metal material, wear mask, unidirectional sky during air-breathing The valve closing of gas flowing valve 4, during expiration, the valve of one-way air flowing valve 4 is opened, only by mistake during air-breathing Entering air at filter disc, be effectively improved the filter efficiency of filter, the water droplet of mask internal condensate is by unidirectional sky Gas flowing valve 4 is discharged, and cover layer 5 selects textile material, is filled by mode lids such as slide fastener, snap-fastener or stickups Outside cover body 6, during use, cover layer 5 filters out visible particle thing, simultaneously spraying figure on cover layer 5 Case, plays beauty function.

As it is shown in figure 1, on the basis of technique scheme, it is that diameter is big that multiple described filter discs place through hole 2 The little circular port not waited.Being arranged such, meet actually used needs, filter disc places the diameter of through hole 2 at 0.5cm To 1.3cm, meet normal exhalation air-breathing needs when mask uses.

As it is shown in figure 1, on the basis of technique scheme, on described cover body 6, filter disc places the individual of through hole 2 Number is two.It is arranged such, it is ensured that while mask normally uses, reduces filter disc and place the quantity of through hole 2, Reduce manufacturing cost, meet actually used needs.

Restriction to this utility model protection domain, one of ordinary skill in the art should be understood that in this practicality new On the basis of the technical scheme of type, those skilled in the art need not to pay that creative work can make is each Plant amendment or deformation still within protection domain of the present utility model.
