Abstract

The utility model provides a mouth-muffle applied to the mouth-muffle, which comprises an outer layer and a filtering layer; the mouth-muffle also comprises a blowing device for blowing air to the mouth-muffle. For the adoption of the technical scheme provided by the utility model, the blowing device blows air inside, therefore, the resistance of the filtering layer of the mouth-muffle can be overcome, and the wearer can easily breath in, meanwhile, a movable valve is opened during breathing out, which makes the exhaled gas be timely discharged, therefore, a good gaseous environment helping the wearer is created in the mouth-muffle. Additionally, the filtering layer of the mouth-muffle can be replaced, therefore, the using cost of the mouth-muffle can be very low, and the economic benefit and the social benefit are very obvious.

Description

A kind of mouth mask

Technical field

The utility model relates to mouth mask, specifically, relates to and a kind ofly can make the wearer breathe mouth mask smoothly.

Background technology

The button cover is as a kind of protective articles, can prevent the injury of germ, toxic gas, dust effectively to human body, therefore be widely used in some occasions, for example there are the place of pernicious gas or dust in the public place during hospital, the disease transmission, mine etc.Differently derived numerous different kinds and selected for use now for consumers according to what use object and applicable situation.But; though now commercially available mouth mask is various in style; can satisfy the basic demand of protection; but but ubiquity the shortcoming that the user wears the back unsmooth breath; and the general tight more breathing of the many more safeguard procedures of filter course will be painstaking more; that is to say the contradiction between existing mouth mask existence protection effect and wearer freely breathe.

Therefore, need a kind of technical scheme, the contradiction between the protection effect of solution mouth mask and wearer freely breathe makes mouth mask in the protection wearer, can not hinder wearer's breathing.

The utility model content

The purpose of this utility model is to provide a kind of mouth mask, is intended to solve the problem of existing mouth mask wearer unsmooth breath.

The utility model is achieved in that a kind of mouth mask, comprises skin and filter course, and described mouth mask also comprises the blowing device of drying in described mouth mask.

Described blowing device is arranged on the described skin.

Described outer perforate, described blowing device is installed in the described hole.

Described blowing device is installed on the described skin by the mode of gluing or snap fastener.

Be provided with protrusion between described skin and the filter course, described protrusion makes between described skin and the filter course and keeps certain clearance, is convenient to circulation of air.

Position corresponding with mouth mask wearer lower jaw part on the described skin is provided with movable valve, and described movable valve is closed when the mouth mask wearer is air-breathing, opens during expiration.

Described blowing device is battery-driven hair-dryer.

Described skin is made with the flexible thin-film material.

Described filter course and described mouth mask flexibly connect, and are convenient to change.

Described outer field edge stretches out and forms a circle plane, is convenient to paste the adhesive sticker or the nylon buckles cloth of the fixed described filter course of cementation.

The technical scheme that adopts the utility model to provide, owing to there is blowing device to blow to the inside, can overcome the resistance of mouth mask filter course, make the wearer easily air-breathing, also have movable valve when giving vent to anger, to open simultaneously, allow the waste gas of breathing out in time discharge, thereby in mouth mask, create the good gaseous environment that helps the wearer.In addition, because the filter course of this mouth mask can change, thereby to use the cost of this mouth mask will be very cheap, and economic benefit and social benefit are all fairly obvious.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

The mouth mask that the utility model provides utilizes power that air is pressed in the mouth mask, makes to keep suitable malleation in the mouth mask, wears the problem of unsmooth breath behind the mouth mask with solution.The mouth mask that the utility model embodiment provides has embodied the three parts of this mouth mask as shown in Figure 1 among Fig. 1: the skin 1 of mouth mask, be installed in the hair-dryer 2 on outer 1 and be installed in movable valve 3 on outer 1.

Fig. 2 is the longitudinal sectional view of the mouth mask that provides of the utility model embodiment, and it comprises outer 1, hair-dryer 2, movable valve 3, be clipped in outer 1 and filter course 5 between protrusion 4 and filter course 5.Wherein, outer 1 is the film made from the plastic and flexible material, and its middle and upper part has circular hole, is used to install hair-dryer 2, and the middle and lower part has less hole, is used for installation activity valve 3.The concrete mounting means of hair-dryer 2 and movable valve 3 can be gluing, also can snap fastener, if the latter, as long as when making outer membrane, mould the plastic emitting nail.Filter course 5 is removable, as an example, and the crimping that turns in outer 1 edge can be moulded, such version both can make things convenient for the embedding at filter course 5 edges, was convenient to change filter course 5, also can allow the wearer feel comfortable.Certainly, other form also can be made in outer 1 edge, and as shown in Figure 3, outer 1 edge stretches out and forms a circle plane, is convenient to paste sticking adhesive sticker or nylon buckles cloth, and is easy to connect when guaranteeing to change filter course 5.In addition, form the space for making between skin 1 and the filter course 5,, be convenient to circulation of air so that keep certain clearance between skin 1 and the filter course 5, way is to go out some little protrusions 4 in outer 1 interior dough model, these protrusions 4 be in outer 1 and filter course 5 between.

Hair-dryer 2 is selected for use battery-driven, preferably select for use centrifugal, the hair-dryer of this model of BFBO412HA for example.After hair-dryer 2 started, hair-dryer 2 was constantly dried in mouth mask, makes the malleation that keeps appropriateness between skin 1 and the filter course 5, and the mouth mask wearer picks up gas has not so just had resistance.Movable valve 3 can be used the product of 3M company, and the movable valve of the said firm attaches filter screen.Movable valve 3 can be opened in the mouth mask wearer exhales automatically as air-outlet valve, closes automatically in the time of air-breathing.Filter course 5 adopts the filter course of general mouth mask, just leaves the hole at the correspondence position of movable valve 3 and comes just.

Needn't La Detai when this mouth mask is worn tight, do not require that mouth mask closely contacts with wearer's face everywhere, this is to have malleation to exist because enter the air of mouth mask, and promptly air inflow is slightly larger than the exhalation amount, thereby needn't worry that the air of filtered enters from partial aperture.

These two cooperation of hair-dryer 2 and movable valve 3, just can overcome the resistance of mouth mask filter course, make the wearer easily air-breathing, open when giving vent to anger owing to movable valve simultaneously, allow the waste gas of breathing out in time discharge, thereby in mouth mask, create the good gaseous environment that helps the wearer, more help wearer's health, the problem of unsmooth breath when simultaneously also having overcome existing mouth mask and wearing.

The technical scheme that concrete application the utility model provides is that the described hair-dryer 2 of the utility model embodiment can be other blowing device, is not limited to hair-dryer.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
