Abstract

The invention relates to an isolation type mask with an inspiration cavity and an expiration cavity. The isolation type mask is characterized in that an inspiration valve is arranged in the inspiration cavity; an expiration valve is arranged in the expiration cavity; a gas purifying core is mounted in the inspiration cavity; a sterilization material, an adsorption material, a filtering material, a harmful gas removal material and a cleaning material are placed in the gas purifying core. The isolation type mask provided by the invention has the beneficial effects that the inspiration cavity is separated from the expiration cavity, and carbon dioxide exhaled by normal people and bacterial viruses exhaled by patients are not absorbed into a human body; the inspiration cavity can effectively prevent bacterial viruses, haze and harmful gases from being absorbed into a human body; a user does not feel muggy in summer, and the eyelashes of the user do not get frosted in winter; the expiration cavity has a good effect on traffic police on duty and in force drills and patrol speeches. According to the isolation type mask provided by the invention, the inherent structure of a mask is changed, and the isolation type mask enters the market as an upgrading product of a traditional mask, is used as an innovative product for haze protection, and has broad market prospects.

Description

There is the isolated mouth mask in suction muffler and expiration chamber

Technical field

There is the isolated mouth mask in suction muffler and expiration chamber, belong to amenities technical field.

Background technology

Tradition mouth mask, is the rectangle cloth bag made from 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 continues has always used decades.According to Beijing medicine equipment inspection institute sodium chloride with 0.3 micron in closed environment, common mouth mask is detected: the transmitance of common mouth mask sodium chloride particulate is 85.6%, result shows, common mouth mask is inoperative to haze, and just solution is become or be suspicious.

In recent years, due to the appearance of PM2.5, very fast for the mouth mask development of haze protection, make the kind of mouth mask suddenly many, hemispheric mouth mask, with the mouth mask of outlet valve, the gauze mask miscellaneous such as nose cup that only covers nose progressively comes into the market; Also there is variation along with the progress of material science and technology in the material of manufacturing mouth mask, there is unprecedented variation in mask material, the multiple materials such as nonwoven, fusion spray cloth, static cotton, NACF are used for making mouth mask, and the function of mouth mask is greatly improved.

At present, these mouth masks on market have a common feature, air-breathing exactly and expiration is carried out in same position, comprise the scale mask that half face is covered and the little nose cup only nose being covered, result in the air-breathing expiration in same position is, a part for the carbon dioxide that Healthy People is breathed out sucks back in lung again, and the bacterial virus that sick people breathes out can pass in and out respiratory tract repeatedly, is obviously extremely detrimental to health.Air-breathing and another drawback of carrying out in same position of exhaling is put on mouth mask exactly, and summer is sultry, and winter is ice-cold, and spring and autumn summer in winter is uncomfortable.Even with the mouth mask of outlet valve, can not ensure that the gas of exhalation is all discharged from outlet valve.

, fungi-proofing articles for use dustproof as respiratory tract, in should really playing 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, do not cause damage to user again, is the content that new mouth mask design should be perfect.

Summary of the invention

The invention provides a kind of isolated mouth mask with suction muffler and expiration chamber, be provided with suction muffler and expiration chamber, air-breathing and expiratory phase are separated, in suction muffler, can place as required sterile material, sorbing material, filtering material, pernicious gas and remove one or more of the multiple materials such as material and cleaning material, the present invention has the isolated mouth mask in suction muffler and expiration chamber, the effect that can effectively play anti-haze, bacteriological protection virus when air-breathing and remove pernicious gas, unblocked when expiration, there is no residual gas resorption, body health benefits.

The object of the invention is to be achieved through the following technical solutions:

A kind of isolated mouth mask with suction muffler and expiration chamber, comprise face shield, suction muffler, expiration chamber, be linked with, it is characterized in that: suction muffler is equipped with admission air valve, expiration valve is equipped with in expiration chamber, installing gas Purified core in suction muffler is placed sterile material, sorbing material, filtering material, pernicious gas and removes one or more materials of material, cleaning material in gas purification core, and one end of gas purification core is provided with screen cloth.

Suction muffler and expiration chamber can be designed to arbitrary shape as required, circular, oval, square, rectangle all can, suction muffler and expiration chamber separate, when air-breathing, pass through inspiratory force, make admission air valve in opened condition, air amount, the valve of at this moment exhaling is closed; When expiration, by expiration power, make to exhale valve in opened condition, give off carbon dioxide, at this moment admission air valve is closed.Admission air valve and expiration valve replace open and close, and air-breathing and expiration is taken their own roads, do not interfere with each other, and the carbon dioxide that normal person breathes out, the bacterial virus that patient breathes out can not suck back in human body again.

Installing gas Purified core in suction muffler, in gas purification core, place one or more materials of sterile material, sorbing material, filtering material, pernicious gas removal material, cleaning material, determine kind and the placement order of these materials according to the application request of air pollution environment.Also can place simultaneously the type such as air freshener, aromatic allow people breathe to feel pure and fresh happy material, principle is to be detrimental to health.Gas purification core is independently parts, irregularly changes according to the degree of saturation of institute's adsorption fouling thing.

Before mask designs, must use spatial digitizer to carry out scanning moulding to the profile of multiple human face, fit again type design according to the analysis of scanning synthesis result, can meet most Chinese people's facial seal request.Face shield is three-dimensional shape, is 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.What face shield was tight is attached on the face, and except air intake passage, other position can not enter air.

In expiration chamber, without any the material stopping, can ensure the unblocked of chamber of exhaling, the carbon dioxide of characteristics of contaminated respiratory droplets, can discharge face shield very soon.Meanwhile, the effect of microphone can also be played in expiration chamber, and impulsive force when speech makes the valve open of exhaling, and sound spreads out of by expiration chamber, can be by vexed sound in face shield and can not hear clearly.

The beneficial effect that the present invention has the isolated mouth mask in suction muffler and expiration chamber is:

1, suction muffler and expiration chamber 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, suction muffler is provided with gas purification core, effectively stops that bacterial virus, haze and pernicious gas suck in human body;

3, face shield is not sultry summer, and winter, eyelash was not gone up frost;

4, the convenient speech in expiration chamber, to traffic police on duty, army's rehearsal, patrol have good effect.
