Description

Gauze mask of removable filter core

Technical Field

The utility model belongs to the technical field of the gauze mask, a gauze mask of removable filter core is related to.

Background

The mask is a hygienic product, wraps the mouth and the nose in a wearing mode to achieve the purpose of blocking harmful gas, smell, spray, bacteria and the like from entering and exiting the mouth and the nose of a wearer, and can play a role in relieving cold air flow in winter.

Based on different functions and application ranges, the existing mask is divided into a common civil mask, a medical mask, a protective mask and the like, the filtering effect and the filtering performance are determined by filtering layers of different quantities or materials, the common civil mask has lower requirements on filtering media, the conventional gauze and non-woven fabrics can meet the requirements, places such as germs and the like are isolated as required, the common civil mask is not ideal, the existing mask is manufactured according to requirements and purposes, the filtering effect can not be changed, the purposes can not be changed, people are in different places and different purposes, the single-class mask is difficult to meet the requirements, a large amount of waste is caused, and inconvenience is brought to users.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a gauze mask of removable filter core to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem that how make the usage of gauze mask wider, the filter core dismantled and assembled in order to reduce the waste of gauze mask.

The purpose of the utility model can be realized by the following technical proposal: the mask with the replaceable filter element is characterized by comprising a coating sheet, wherein the coating sheet comprises an inner layer and an outer layer, an interlayer covering an oral-nasal breathing area is arranged between the inner layer and the outer layer, two tearing openings which are symmetrically distributed and can enable the interlayer to be opened are formed in the outer layer, a detachable filter sheet is inserted into the interlayer, the filter sheet, the inner layer and the outer layer are connected through a dismounting assembly, and the dismounting assembly comprises a plurality of magnetic particles, a plurality of iron blocks and a plurality of positioning small holes, the magnetic particles are located on the outer layer of the edge portion of the tearing opening, the iron blocks are arranged on the inner layer and correspond to the magnetic particles one by one, and the positioning small holes are formed in the filter sheet and correspond to the magnetic particles one by one.

Furthermore, the middle of the magnetic particles is provided with a raised head matched with the positioning small hole, and the raised head faces the outer side of the inner layer.

Furthermore, the wrapping sheet is provided with an elastic hanging lug rope.

Furthermore, a nose bridge clamping piece is embedded in the coating piece.

When not needing the cassette, go out to open at tearing the mouth and skin, make inlayer and skin separately, can take out the cassette, then make and tear the mouth and reset, at this moment, this gauze mask is for ordinary protection usefulness, like keep apart haze, dust etc. does not have better isolation bacterium effect, inlayer and skin are gauze or non-woven fabrics.

When a better higher filtering function is needed, the outer layer of the tearing opening is torn, the standby filter sheet is inserted, the positioning small holes can correspond to the raised heads, the filter sheet is positioned and clamped between the inner layer and the outer layer under the magnetic adsorption action of the magnetic particles and the iron block, and the filter sheet can be of a sheet structure with flock spraying cloth.

In order to facilitate the disassembly and assembly of the filter disc, reduce the cost and the size of the filter disc, the area corresponding to the filter disc is only the mouth and nose breathing area, namely the opposite area of airflow during breathing.

Fig. 1 is a schematic structural view of the mask when the outer layer is not torn.

Fig. 2 is a structural schematic diagram of the mask after the outer layer is torn.

Fig. 3 is a schematic view showing the assembly of the magnetic particles and the iron block.

In the figure, 1, inner layer; 2. an outer layer; 3. tearing the opening; 4. a filter disc; 51. magnetic particles; 52. an iron block; 53. positioning the small hole; 54. a raised head; 6. a loop rope; 7. a nose bridge clip.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, fig. 2 and fig. 3, the packaging film comprises a packaging sheet, the packaging sheet comprises an inner layer 1 and an outer layer 2, an interlayer covering the mouth-nose breathing area is arranged between the inner layer 1 and the outer layer 2, two tearing openings 3 which are symmetrically distributed and can enable the interlayer to be opened are arranged on the outer layer 2, a detachable filter sheet 4 is inserted in the interlayer, the filter sheet 4, the inner layer 1 and the outer layer 2 are connected through a dismounting assembly, the dismounting assembly comprises a plurality of magnetic particles 51 positioned on the outer layer 2 at the edge of the tearing opening 3, a plurality of iron blocks 52 which are arranged on the inner layer 1 and correspond to the magnetic particles 51 one by one, and a plurality of positioning small holes 53 which are arranged on the filter sheet 4 and correspond to the magnetic particles 51 one by one.

The middle part of the magnetic particle 51 is provided with a raised head 54 matched with the positioning small hole 53, the raised head 54 faces the outer side of the inner layer 1, the coating sheet is provided with an elastic ear hanging rope 6, and a nose bridge clamping piece 7 is embedded in the coating sheet.

When not needing cassette 4, tearing 3 plays and open outer 2 in mouthful, make inlayer 1 and outer 2 separately, can take out cassette 4, then make and tear mouthful 3 and reset, at this moment, this gauze mask is for ordinary protection usefulness, if keep apart haze, dust etc. do not have better isolation bacterial action, inlayer 1 and outer 2 are gauze or non-woven fabrics.

When a better higher filtering function is needed, the outer layer 2 from the tearing opening 3 is torn, the standby filter sheet 4 is inserted, the positioning small holes 53 can correspond to the raised heads 54, the filter sheet 4 is positioned and clamped between the inner layer 1 and the outer layer 2 under the magnetic adsorption action of the magnetic particles 51 and the iron block 52, and the filter sheet 4 can be of a sheet structure with flannelette.

In order to facilitate the attachment and detachment of the filter 4, and also to reduce the cost and the size thereof, the region corresponding to the filter 4 is only the oronasal breathing region, i.e., the region directly opposite to the airflow during breathing.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
