Abstract
The utility model relates to a protection mask for police. The protection mask comprises a main body and ear bands. The left side and the right side of the main body are respectively provided with an ear band in an adhesion mode. The protection mask is characterized in that the main body is in an olive shape, the middle of the main body is wide, the two sides of the main body are narrow, the middle of the main body protrudes outward to form an arch shape, and the main body is formed by sewing two central filtering parts sequentially. The protection mask for the police has the advantages of being capable of meeting requirements of main technical indexes and ensuring the protection effect, integrating comfort and attractiveness, adapting to working characteristics, and maintaining good police filtration efficiency. The concrete indexes are as follows: purified PM5 is larger than or equal to 95%, and PM2.5 is larger than or equal to 50%; expiration resistance is smaller than or equal to 250Pa, and inspiration resistance is smaller than or equal to 35 Pa (air flow (85+-2)L/min); a dead cavity is about 90cm3, and the concentration of CO2 is 1%; the weight is 30-35g. The protection mask is light so as to be convenient to wear, and capable of sterilizing and removing peculiar smell.
Description
Technical field
The utility model relates to a kind of police protective mask, really to possess the protection effect of guarantor simultaneously, has taken into account again comfortableness and aesthetic property, adapts to work characteristics, maintains the good alert looks of police appearance.
Background technology
Several months, haze weather shrouds the greater part, China central and east, bears down menacingly and the impetus does not subtract, and dense fog causes comparatively serious air pollution.According to the National urban air quality real-time release platform demonstration of China Environmental Monitoring General Station, many ground such as Beijing, Hebei, Shandong air quality reaches severe contamination, and P M2 .5 index presses on towards the maximum of instrument measurable.Much research institutions, scholar all mean when interviewing the reporter, and the fine particle thing carried in haze weather is very big to the human injury, and wherein, PM 2.5 can directly enter lung and blood.
At Jinan, Shandong Province, PM 2.5 indexes were once reaching 207.A Jinan traffic police claims on microblogging, after the cough of similar influenza, the symptom such as uncomfortable in chest appear in the traffic police when 37%, a line traffic police start tentative wear masks on duty on duty.The Shanghai traffic police tackles haze, has started to try on " invisible mask ".With traditional mouth mask, compare, " invisible mask " more is similar to nasal obstruction.It is by the in succession fiber filter disc at two ends of one section support, and nostril is filled in in two ends can play a role, and after putting on, substantially can't see from afar, really can be regarded as " stealthy ".
Have data to show, China traffic police's average life span is far below social average life span.Even be not in haze weather, a line traffic police faces too the health hazard that particulate pollutant, pernicious bacteria and specific peculiar smell are brought in process on duty.
Medical protective mask refers to what the professional health care personnel used in hospital, for preventing some respiratory infectious microorganisms spreading, take and protects medical personnel's healthy protective respirator as purpose at work, take protection water-based particle as main.
It is mainly industrial and mining enterprises that the industrial protection mouth mask is used the crowd, and the obstruct dust of take is main purpose.Not of uniform size, the majority of material thing is non-water-soluble suspension.
In sum, do not have in the market the Protection Product for atmosphere and vehicular engine exhaust pollutant.Medical mask can't intercept the oiliness particle; Anti-dust respirator can't intercept harmful bacterial classification and peculiar smell
;common civilian mouth mask, even 16 layers, still can not play good resistance dirt effect.Therefore, the exploitation of police protective mask need to, from traffic police's actual working environment, be developed efficient Protection Product according to its occupational characteristic.
Summary of the invention
For overcoming the defect of prior art, the utility model provides a kind of police protective mask.The technical solution of the utility model is:
The utility model has the advantages that: both met the key technical indexes, guaranteed protection effect; Take into account again comfortableness and aesthetic property, adapted to work characteristics, maintained the good alert filter efficiency of police appearance; Specific targets are as follows: purify PM 5>=95% and PM 2.5>=50%; Expiratory resistance≤250Pa, inspiratory resistance≤350Pa (air mass flow (85 ± 2) L/min); The about 90cm of dead space
3,, CO
2concentration<1%; Weight: 30-35g, light being easy to worn; Can sterilization and removal peculiar smell.
The accompanying drawing explanation
Fig. 1 is agent structure schematic diagram of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of police protective mask, comprise main body and ear band 5, the left and right sides of the described main body ear band 5 that bonds respectively, ear band 5 is elastomeric material, terylene covered yarn is made, bonding through hot rolling and main body, the narrow olive shape in wide both sides in the middle of described main body is, and intermediate portion outwardly convex formation arch, this main body is sewed up and is formed successively by center filter element 1 and center filter element 2; The mid portion of main body is designed to arch, and built-in flexible stand 6, in the situation that assurance is closely sealed, can form at the mouth and nose place cavity.While breathing like this, the area of air stream warp is larger, and resistance is less, and sensation can be comfortable many.But cavity is too large, also can make the wearer suck the last CO breathed out
2concentration excessive, surpass 2% and there will be the respiratory disorder symptom, reduce visual range (visual field) simultaneously, affect normal activity.Therefore, the size of dead space is wanted appropriate design, tentative 90cm
3left and right.
The upper/lower terminal of described main body is sewed with respectively filter element 3 and lower filter element 4, and described upper and lower filter element all tilts to the inside, and is symmetrical arranged along main body.The suture zone that dotted line in figure is ultrasonic sawing machine, link together center filter element 1, center filter element 2, upper filter element 3 and lower filter element 4 by ultrasonic sawing machine.
