Description

Portable dustproof respirator

Technical field

The utility model relates to a kind of dustproof articles for use, particularly a kind of Portable dustproof respirator.

Background technology

Recent haze in all parts of the country is frequently existing, fogged-in, and visibility only has hundred meters of left and right.This diastrous weather of haze, not only cause under low visibility, affect traffic safety, and causing air quality to decline, influence ecological environment, tends in air with bacterium and virus, easily cause infectious disease diffusion and various diseases to occur, very easily cause respiratory tract infection, angiocardiopathy, brings larger harm to health.So no matter be that traffic police on duty under severe traffic environment or the floor manager person in high dust, high pollution environment etc. belong to and need to wear mouth mask staff, yet wear the normal work that mouth mask can affect this class staff to a certain extent, the one, cannot blow a whistle, the 2nd, exchange inconvenience with people.The staff such as traffic police or commander has to command in the situation that cannot wearing anti-dust respirator, has occurred in various degree cough and the symptom such as uncomfortable in chest.Lack a kind of Portable dustproof respirator not increasing burden, under the healthy prerequisite of protection, do not affect the normal work that need to blow a whistle and talk.

Utility model content

The purpose of this utility model is to provide a kind of conveniently blows a whistle, the Portable dustproof respirator of convenient speech.

The utility model provides a kind of Portable dustproof respirator of wearing for can blow a whistle time, has such feature, comprising: cover body, and middle part is provided with opening; Frenulum, symmetry is arranged on four jiaos of cover body; Cover lid, be arranged on the outside of opening, there is the size that is greater than opening, comprise the upper edge and the arc lower edge that are connected with cover body one; And slide fastener, the lower limb of connection opening and arc lower edge, wherein, cover lid covers in opening by slide fastener integral body or part.

In Portable dustproof respirator of the present utility model, can also there is such feature: wherein, the radius of curvature that arc lower edge has is larger, and slide fastener is by arranging and have identical radius of curvature along arc lower edge, for conveniently pulling open from the beginning to the end or drawing.

Effect of the present utility model is:

The Portable dustproof respirator that the utility model provides can meet when normal work protects health to avoid dust to healthy impact; no matter be that traffic police or the floor manager person in high dust, high pollution environment on duty can unzip under severe traffic environment, thereby the cover lid with dustproof effect opened and whistled or talk from opening part.In the time of need to whistling, because the size of opening is slightly larger than whistle, whistle can directly be penetrated cover body and be contacted with mouth, and now nose is still in protected dustproof region, and without integral body, mouth mask taken off.When not needing to whistle, can be by the cover lid with dustproof effect by slide fastener by the complete drawing of opening.

The Portable dustproof respirator that the utility model provides is simple in structure, can be positioned over pocket and be convenient for carrying, even also not burdensome increase heavy burden senses of effect personnel long periods of wear such as the light traffic police of deal or commanders.

The zipper that the Portable dustproof respirator that the utility model provides adopts, repeatedly Reusability durability is strong.Slide fastener is connected that the arc lower edge place better appearance of cover lid is set is affine.The upper edge of cover lid is connected with slide fastener with the arc lower edge that cover body one is connected, covers lid, and position stability maintenance is high, without worrying the problems such as cover lid loss., the slide fastener of cover lid by part drawing still covered in opening and ought in emergency circumstances can only pull open part slide fastener and blow a whistle,, the good dust-proof effect of flexibility is excellent.

Accompanying drawing explanation

Fig. 1 is the structural representation of Portable dustproof respirator in embodiment of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1, the Portable dustproof respirator in the present embodiment 100 comprises cover body 1, frenulum 2, cover lid 3 and slide fastener 4.Four root system bands 2 are arranged on four jiaos of cover body 1 by symmetrical.

The middle part of cover body 1 is provided with opening 1a corresponding to the position of mouth, and the size of opening 1a is slightly larger than the size of the whistle not showing in Fig. 1, and the mouthpiece of the whistle not showing in Fig. 1 can be penetrated to stretch into by opening 1a to contact with mouth.

Cover lid 3 is arranged on the outside of opening 1a, and the size of cover lid 3 is greater than the size of opening 1a, can cover in whole opening 1a completely.In the present embodiment, cover the upper edge 3a that lid 3 has yi word pattern, upper edge 3a is connected with cover body 1 one, and cover lid 3 also has arc lower edge 3b, and the following 3b of this arc is larger along the radius of curvature having.

Slide fastener 4 is connected between the lower limb and arc lower edge 3b of opening 1a, and cover lid 3 can integral body cover in opening 1a by slide fastener 4, can partly cover in opening 1a again.Slide fastener 4 arranges along arc lower edge 3b, and slide fastener 4 has identical radius of curvature, and radius of curvature is larger, and this arc is milder, zips so and without turning, pulls open or drawing from the beginning to the end for 4 o'clock, handled easily.

The effect of utility model and effect

In sum, effect of the present utility model is:

The Portable dustproof respirator that the utility model provides can meet when normal work protects health to avoid dust to healthy impact; no matter be that traffic police or the floor manager person in high dust, high pollution environment on duty can unzip under severe traffic environment, thereby the cover lid with dustproof effect opened and whistled or talk from opening part.In the time of need to whistling, because the size of opening is greater than whistle, whistle can directly be penetrated cover body and be contacted with mouth, and now nose is still in protected dustproof region, and without integral body, mouth mask taken off.When not needing to whistle, can be by the cover lid with dustproof effect by slide fastener by the complete drawing of opening.

The radius of curvature that in the Portable dustproof respirator that the utility model provides, slide fastener has is larger, radius of curvature is larger, and this arc is milder, while zipping so, can disposablely pull open from the beginning to the end or drawing, handled easily, avoids occurring cannot pulling open or the situation of drawing because of the stuck slide fastener in turning.

Above-mentioned embodiment is preferred case of the present utility model, is not used for limiting protection domain of the present utility model.
