Description

The isolated mouth mask of a kind of mouth and nose

Technical field

The utility model relates to a kind of mouth mask, especially the isolated mouth mask of a kind of mouth and nose, the isolated mouth mask of described mouth and nose is able to provide multiple respiration channels to wearer, each described respiration channel is isolated mutually, so that the gas that wearer exhales/inhales is not polluted mutually, wearer is able to the free interchange of cosily speaking of oral area simultaneously.

Background technology

Traditional mouth mask, is divided into disposable medical mask and reusable functional mouth mask.Two kinds of common mouth masks of tradition are all to cover by mask main body the form that wearer's mouth and nose make air enter wearer's respiratory tract after mask main body is filtered again to provide cleaner air to breathe for it to wearer simultaneously, and tightly cover wearer's mouth and nose with pursue mouth mask can have a good sealing effectiveness, when preventing that the harmful substances such as dust from entering wearer's respiratory tract, the existence of mouth mask but makes wearer's the interchange of speaking add no small obstruction.

First, wearer cannot freely cosily speak simultaneously in the situation that being covered mouth and nose by mask main body, even if the three-dimensional mouth mask of cutting out design then coming out makes wearer's lip have more activity space in the time exchanging, but because mask main body is eliminated not yet to the insulating effect of air, the propagation of sound has still been subject to very large obstruction, make speaking of wearer exchange the effort that seems very, particularly in air, have compared with multi-pollutant or strong wind, severe cold people and extremely need mouth mask to resist under the environment of severe cold block contaminants.For the mouth mask with the different filtering function layers of multilayer, in possessing air in the good filtering function of poisonous and harmful substance, along with the increase of functional layer, wearer and people carry out free and comfortable speaking and exchange and but seem especially unable to do what one wishes.Secondly, traditional mask main body part all by cotton, yarn, spin cloth or various filter course is formed, all can not isolate according to wearer's facial curve the respiratory tract that enters again wearer after an airtight space forces air via mask main body well, that is to say, the air that poisonous and harmful substance is contained in the external world still can be inhaled into by the gap between mask main body and wearer's face wearer's lung, therefore, so-called sealing effectiveness is non-existent actually.Moreover, when mouth and nose are covered together, the same mask main body that must see through of waste gas of breathing out due to wearer is discharged to external environment, the steam that inevitably can produce in the time exhaling because of wearer is stranded in mouth mask inner surface and makes mask main body become humid, bring discomfort to wearer, especially while suffering from the breathing problems such as influenza as wearer, therefore the germ that the waste gas of breathing out with wearer is discharged from more can be detained and accumulate in the inner surface of mask main body, is extremely unfavorable for that wearer breathes healthily.In addition, also be very importantly, in the situation that temperature is lower, if the people of wearing spectacles wears mouth mask simultaneously, waste gas with steam can make lens atomization badly influence the definition of wearer's vision by the passage forming between wing of nose both sides and mask main body, even if then occur the generation that prevents this phenomenon with the mouth mask of adjustable nose clip, but still be easy in wearer's body action instead because the good plasticity of adjustable nose clip loses this effect.

In view of above reason, in air pollution increasingly serious today, mouth mask market urgently provides the poisonous and hazardous impurity in a kind of effectively filtered air of people and can bring wearer's safety and comfortable mouth mask.
