Abstract

The utility model relates to a mouth-nose mask and belongs to the technical field of hygienic products. According to the technical scheme, the mouth-nose mask comprises an inspiration channel and an expiration channel. The mouth-nose mask is characterized in that the inspiration channel and the expiration channel are mounted on the mouth-nose mask, an inspiration valve is arranged on the inspiration channel, and an expiration valve is arranged on the expiration channel; a plurality of interlayers are arranged on the inspiration channel, and sterilizing materials, adsorption materials and dustproof materials are placed in the interlayers as needed; the inspiration valve is open through inspiration force, and then air is inhaled; the expiration valve is open through expiration force, and then carbon dioxide is exhaled. The mouth-nose mask has the advantages that due to the fact that the inspiration channel and the expiration channel are separated, the carbon dioxide and bacterial viruses exhaled can not be inhaled into the human body again; due to the fact that the sterilizing materials, the adsorption materials and the dustproof materials are placed in the interlayers of the inspiration channel, bacterial viruses and dust are effectively prevented from being inhaled into the human body.

Description

Oronasal mask

Technical field

An oronasal mask, belongs to amenities technical field.

Technical background

Tradition mouth mask, is to make rectangle cloth bag with gauze or other cloth, and cloth bag both sides are provided with ear muff, hangs on ear, as dustproof, fungi-proofing use.This mouth mask has been used decades, although using material and mouth mask style to change to some extent, there is no large variation.

Tradition mouth mask has the following disadvantages: the one, and people's breathing is with nose, and when nose is cranky, also useful mouth is breathed, and traditional mouth mask is all built more than half face below eyes, designs unreasonable; The 2nd, because face is uneven, particularly nose is outstanding, and the mouth mask of plane can not be tight what buckle on the face, at least top of nose gas leakage; The 3rd, the thin amazing effect of mouth mask, air-breathing effort that mouth mask is thick; The 4th, the exhale part of the carbon dioxide of breathing out of normal person sucks back in body again, the bacterial virus respiratory tract of repeatedly coming in and going out when sick, health risk; The 5th, wear masks sultry summer, the frost on northern eyelash that wears masks winter, and spring and autumn summer in winter is uncomfortable.

, fungi-proofing articles for use dustproof as respiratory tract, when should really play a role in function, can not bring infringement to application person.Serious in air pollution, under the environment that haze, sandstorm occur repeatedly, the effect of mouth mask seems and is even more important.

The function of mouth mask being improved, increase scientific and technological content, really play dustproof, fungi-proofing effect, to user, do not cause damage again, is the content that new mouth mask design should be perfect.

Summary of the invention

The utility model provides a kind of oronasal mask, be provided with air intake passage and exhalation passages, air-breathing and expiratory phase are separated, in air intake passage, can place as required one or more of the multiple materials such as sterile material, sorbing material and dust-proof material, the utility model oronasal mask, can effectively play dustproof, fungi-proofing effect, body health benefits.

The purpose of this utility model is achieved through the following technical solutions:

A kind of oronasal mask, comprise air intake passage, exhalation passages, it is characterized in that: air intake passage, exhalation passages are arranged in oronasal mask, on air intake passage, be provided with admission air valve, in exhalation passages, be provided with expiration valve, on air intake passage, be provided with some interlayers, in some interlayers, place as required sterile material, sorbing material, dust-proof material.By inspiratory force, make admission air valve be admission air valve open mode, air intake; By expiration power, the valve that makes to exhale is expiration valve open mode, gives off carbon dioxide.The face that is provided with in oronasal mask pastes, and is provided with fixed band in oronasal mask.

Air intake passage and exhalation passages separate, and when air-breathing, by inspiratory force, make admission air valve be admission air valve open mode, air amount, and the valve of at this moment exhaling is closed; During expiration, by expiration power, the valve that makes to exhale is expiration valve open mode, gives off carbon dioxide, and at this moment admission air valve is closed.Admission air valve and expiration valve alternately open and close, the carbon dioxide that normal person breathes out, and the bacterial virus that patient breathes out can not suck back in human body again.

Air intake passage is provided with some interlayers, quantity and the thickness of interlayer are set according to application request, in some interlayers, place as required one or more of the materials such as sterile material, sorbing material, dust-proof material, also can place the types such as air freshener, Jasmine aromatic allow people breathe to feel that smooth and easy material, principle are to be detrimental to health.

Oronasal mask is only worn over the position of nose and mouth, be not tightly smother nose and mouth, but leave certain space, the very design of hommization, puts on a kind of comfortable sensation.Oronasal mask does not relate to other position of face, utilizes face to paste tight being attached on the face, and except air intake passage, other position can not enter air, and oronasal mask utilizes fixed band to hang on ear.

In exhalation passages, without any the material stopping, can guarantee the unblocked of exhalation passages, the carbon dioxide of characteristics of contaminated respiratory droplets, can very fast outlet nose cup.

The beneficial effect of the utility model oronasal mask is:

1, air intake passage and exhalation passages separate, the carbon dioxide that normal person breathes out, and the bacterial virus that patient breathes out can not suck back in human body again;

2, air intake passage is provided with some interlayers, places one or more of the materials such as sterile material, sorbing material, dust-proof material in interlayer, effectively stops that bacterial virus and dust suck in human body;

3, oronasal mask is only worn over the position of nose and mouth, does not relate to other position of face, and summer is not sultry, and winter, eyelash was accessible.
