Abstract

A filter sheet of a mask comprises two surface cloth layers, a filter layer and an aromatic layer, wherein the inside and outside of the surface cloth layers are correspondingly superposed and the peripheries are bonded with each other; the filter layer and the aromatic layer are correspondingly superposed and clamped between the surface cloth layers; the filter layer is used for filtering the toxic gas; and the aromatic layer is used for giving out the aromatic odor. Through the aromatic layer, the utility model can continuously emit the aromatic odor to deodorize; therefore, the utility model has excellent using functions.

Description

The filter disc of mouth mask

Technical field

The utility model relates to a kind of filter disc, particularly relates to a kind of filter disc that is housed in the mouth mask in the mouth mask replaceably.

Background technology

Air and environmental quality are low now, various infectious diseases irregularly break out, avoid sucking or the exhalation harmful substance in order to cover mouth and nose, existing increasing user of service can wear mouth mask when the turnover particular place, therefore the utilization rate of mouth mask is to grow with each passing day, and manufacturer is is also researched and developed improvement at various mouth masks.Mouth mask roughly can be divided into two kinds according to its occupation mode difference at present, first kind of deserted mouth mask for promptly losing after general the using, and second kind is that replaceable filter disc is with reusable alternate form mouth mask.With regard to the filter disc in being housed in this alternate form mouth mask, it mainly is to be used to filter toxic gas or absorbing pathogenic bacteria, there is no the function of comprehensive clean smell, if therefore be in the dirty smelly environment, the user of service who wears mouth mask still can smell stink.

The utility model content

The purpose of this utility model is that a kind of filter disc that gives out the mouth mask of fragrance is being provided.

The filter disc of the utility model mouth mask comprises two table layer of cloths, a filter course and a fragrance layer.The inside and outside corresponding stacked and periphery of described table layer of cloth is bonded to each other.This filter course is arranged on described table cloth interlayer.This fragrance layer is arranged on described table cloth interlayer and corresponding stacked with this filter course.

The beneficial effects of the utility model are: this filter disc can filter poison gas by the setting of this filter course, and sees through the setting of this fragrance layer, then more can be fragrant, and the energy mask malodors, reach preferable function of use.

Description of drawings

Fig. 1 is that a preferred embodiment of the utility model filter disc is housed in the use schematic diagram in the alternate form mouth mask;

Fig. 2 is a front elevational schematic of the preferred embodiment;

Fig. 3 is a part of cross-sectional schematic of the preferred embodiment.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is elaborated:

Consult Fig. 1, Fig. 2 and Fig. 3, the preferred embodiment of the utility model filter disc, be to be used for to be housed in an alternate form mouth mask 1 with changeing, and the corresponding mouth and nose place that is positioned at the user of service, form and structure as for this alternate form mouth mask 1, be not the utility model emphasis, so no longer describe in detail at this.This filter disc 2 comprises: two table layer of cloths 21, a filter course 22 and a fragrance layer 23.

Described table layer of cloth 21 is that the stacked and periphery of inside and outside correspondence is bonded to each other, and is to define one jointly to be installed in space 24, and has a plurality of inside and outside perforations and the air-vent 211 of each interval.Described table layer of cloth 21 is all a soft gas permeable material, for example weave cotton cloth, adhesive-bonded fabric, thermoplastic polyurethane elastic film (TPU film), thermoplastic elastic film (TPE film), polyurethanes film (PU film), polypropylene screen (PP film), can be used for intercepting foreign matters such as airborne saliva, dust, present embodiment is the adhesive-bonded fabric material that adopts the tool gas permeability.Described table layer of cloth 21 can be rectangle, circle or oval, on making, the periphery of present embodiment table layer of cloth 21 be hot binding together, its shape and combination are not exceeded with present embodiment certainly.

This filter course 22 has a filter cloth body 221 that is arranged on 21 of described table layer of cloths, and a plurality ofly coheres on this filter cloth body 221 and the filtered particles 222 that can be used for adsorbing poison gas.Described filtered particles 222 is powdery or granular active carbon material, can see through it and have the microcellular structure in space, and can have bigger surface area, in order to toxic component in the deaeration, or germ is adsorbed in the micropore, avoid fine dust or bacterium to invade human body, to reach dustproof, filter poison and fungi-proofing effect, just the method for making and the function of this filter course 22 are general technology, so no longer describe in detail at this.

This fragrance layer 23 is arranged on 21 of described table layer of cloths, and it is corresponding stacked with this filter course 22, be a tool gas permeability and the fragrant cloth body that can give out fragrance, this fragrance cloth body can be made by soft gas permeable material, for example weave cotton cloth, adhesive-bonded fabric, thermoplastic polyurethane elastic film (TPU film), thermoplastic elastic film (TPE film), polyurethanes film (PU film), polypropylene screen (PP film), the through hole (figure does not show) of a plurality of increase gas permeabilities can be set, and the user of service can select the fragrance desiring to distribute, lavender fragrance for example, rose fragrance, citrus aromes, mint flavored, lemongrass fragrance, citrus scented, the santal flavor, outstanding markon's fragrance, plant polyphenol powde etc., not only can continue fragrant, promote deodorizing effect to purify air, more can have sterilization, the effect of sterilization.On making, present embodiment is that fragrant cloth body is immersed in the essence or solution of the specific fragrance of tool, then take out dry again to become a fragrance layer 23, the fragrant film that a slice can certainly be made by fragrant powder and viscose blending, hot pressing is cohered on fragrant cloth body becomes one fragrant layer 23 with compound, and the manufacture of this fragrance layer 23 is not exceeded with present embodiment.

During use this filter disc 2 packed in this alternate form mouth mask 1, again this alternate form mouth mask 1 is worn mouth and nose place in the user of service, when the user of service breathes, air promptly can be via these filter disc 2 turnover, this moment can be by noxious material, germ, stink and the micronic dust in these filter course 22 filtered airs, and sees through this fragrance layer 23 and give out fragrance and hide stink, and more delicate fragrance is pleasant on wearing to allow the user of service, can promote the function of use of alternate form mouth mask 1, also valuable aspect prevention and health care.

What must further specify is, the filter course 22 of present embodiment is stacked on top of each other with fragrance layer 23, and be interposed in 21 of described table layer of cloths, and described table layer of cloth 21, filter course 22 with the periphery of fragrance layer 23 by hot binding, this fragrance layer 23 can select to be arranged at the inboard or the outside of this filter course 22, the inboard that the fragrance layer 23 of present embodiment is arranged near user of service's mouth and nose.Certainly in design, also can only allow the periphery of described table layer of cloth 21 mutually combine, and make this filter course 22 dwindle area, be contained in this with correspondence to be installed in the space 24, no longer describe in detail at this with this fragrance layer 23.

In sum, filter disc 2 of the present utility model can filter poison gas by the setting of this filter course 22, and see through the setting of this fragrance layer 23, then more can be fragrant, and can mask malodors, reach preferable function of use, to improve the epidemic prevention ability, so can reach the purpose of this utility model really.
