Description
Technical field
The utility model is related to mask technical fields, relate more specifically to a kind of mask.
Background technology
The mask of the prior art, it orally covers air outside mask by the negative pressure formed in mask when user's air-breathing
In filter layer mask for inhalation, the normal pressure formed in mask when being exhaled by user arranges air in mask through mask filter layer
Go out mask.The negative pressure in mask that user is formed in air-breathing can prevent in the lung of the gas stream access customer in mask, be formed
Inspiratory resistance；The normal pressure in mask formed when user exhales can prevent the gas in user's lung from breathing out, and form resistance of exhaling
Power.Inspiratory resistance and expiratory resistance are collectively referred to as respiratory resistance, and respiratory resistance can allow user to feel expiratory dyspnea.
Another mask of the prior art uses outlet valve, the problem of can improving expiratory resistance.Users wear this
Mask, in air-breathing, outlet valve is closed；When exhaling, the positive pressure formed in mask is in outlet valve, when normal pressure is more than
After certain value, outlet valve can be opened, and be conducive to gas in mask and be discharged so that normal pressure will not continue to increase very much.But this
The inspiratory resistance problem of kind mask is not improved well, and so that outlet valve is opened when expiration, it is still desirable to certain
Normal pressure, that is, still have expiratory resistance, so, which is not fully solved respiratory resistance problem.
A kind of scheme in the prior art needs to switch positive and negative rotation, is not easy reality using a fan for air-supply and air draft
The now rapid switching of air-supply and air draft.
