Description
Technical field
The utility model is related to a kind of mouth mask, in particular, and it is related to a kind of safety goggles and hazed mouth mask.
Background technology
Mouth mask is a kind of amenities, refer generally to be worn over nose and mouth be used for filter entrance mouth and nose air, to reach resistance
The harmful gas of gear, smell, the spittle pass in and out the apparatus of wearer's mouth and nose, are made with gauze or paper etc..Mouth mask is to entering lung
Air has certain filtration, and when respiratory infectious disease is popular, in the environment of the pollutions such as dust during operation, wear masks tool
There is extraordinary effect.
Haze is the result that specific weather condition interacts with mankind's activity.The economy of high density population and social activities
A large amount of fine particles will necessarily be discharged（PM 2.5）, once discharge exceedes atmospheric air circulation ability and carrying degree, fine particle concentration
By continued accumulation, if now influenceed by quiet steady weather etc., easily there is large-scale haze.
The North China most area of the second half year in 2016 is shrouded by haze, and PM2.5 continues quick-fried table, and the body of the people is good for
Health produces strong influence, and now when people need to carry out outdoor trip, the important function of mouth mask is more embodied
！
Although mouth mask can reach the function of stopping germ, dust or floating substance, in use, particularly
In winter, the user of wearing spectacles, the hot gas of exhalation can rise along mouth mask, and cause eyeglass to haze, and this can cause
User during walking or cycling fail to understand by sight, easily occurs traffic accident.Therefore the winter person of wearing glasses is in Dai Kou
Very big puzzlement can be produced while cover, this problems demand is solved.
If patent publication No. is a kind of Antifogging mask mentioned in CN102948934A Chinese patent, its technology used
Scheme is：It is made up of a cover body, and an exhaust structure below cover body medial surface.The side of cover body two is provided with relatively
Tool, and exhaust structure is a strip contact piece, its both ends is fixed in both sides or two ends below cover body medial surface, the contact piece
Apical margin sets an at least knuckle so that the contact piece apical margin is shorter in length than root edge length so that the contact piece and cover body medial surface
A through hole formed below.What it was produced has the beneficial effect that：The Antifogging mask is in use, the sky that the user worn glasses is breathed out
Gas is discharged by the through hole, and from cover body medial surface root edge, with lacking that sight produced by avoiding glasses because hazing is failed to understand
Fall into.
However, above-mentioned mouth mask is in use, due to air-tightness, the hot-air of exhalation will not be completely by setting
The through hole discharge set, still can some by discharging above mouth mask, so as to still glasses can be caused to haze.The utility model
New technical scheme is proposed to solve the above problems.
