Prior to this, the terms or words used in the present specification and claims should not be construed in a conventional and dictionary meaning, and the inventor may properly define the concept of the term to describe his invention in the best way. Based on the principle that there is, it should be interpreted as meaning and concept consistent with the technical idea of the present invention.

Accordingly, the embodiments described in this specification and the configurations shown in the drawings are only a preferred embodiment of the present invention, and do not represent all of the technical spirit of the present invention, so various equivalents that can be substituted for them at the time of the present application It should be understood that there may be water and variations.

As shown in the drawing, the filter replaceable mask 100 according to the present invention is configured to be worn around the user's face, that is, around the nose and mouth to filter dust or viruses, and the filter 120 is located inside, and the filter ( 120 maintains the state attached to the mask body (110).

The filter 120 may be in a form in which various functional filters 120 are stacked, for example, may selectively include a pre-filter, a HEPA filter, a carbon filter, and the like.

And an attachment member 130 is provided at an edge of the filter 120 . The attachment member 130 is attached to the edge of the filter 120 in the form of a closed loop, and is provided at the edge of the filter exposed portion (refer to reference numeral 112 in FIG. 5 ) cut in the mask body 110 . It is attached by the attachment member 130 and the attractive force (引力).

Therefore, the filter 120 can be separated from the mask body 110 when replacing it with another filter 120 after use for a certain period of time. will do In addition, the filter 120 may be exposed to the outside without being covered by the mask body 110 when it is attached to the filter exposing part 112 by manpower.

The mask body 110 is provided with a wire 140 for adhesion. The contact wire 140 is configured to be in close contact with the user's face curve, and a shape memory member is adopted.

Therefore, if the mask body 110 is deformed according to the curve of the face when worn for the first time, this shape is remembered and then returned to the deformed shape when worn later, and lifting of the filter replaceable mask 100 is minimized. Entry of unfiltered contaminated air can be prevented.

An earring strap 150 is provided at the right end of the mask body 110 . The earring strap 150 is made of a closed loop shape and is made of a material having an elastic restoring force.

And the ear strap 150 may be adopted with silicone so as not to get wet with sweat.

On the other hand, an extension string 160 is further provided at the end of the ear string 150 . The extension strap 160 is configured to prevent ear pain that may be caused when the filter replacement mask 100 is worn for a long time using the ear strap 150 .

That is, the extension string 160 is added to the ear string 150 in the form of a closed loop, and a binding hole 170 is provided at the end.

The binding sphere 170 is for restraining the earring strap 150 provided at the pair of extension ends while maintaining the tensile force when pulled toward the back of the head, Velcro tape, a snap button, a ring-shaped plastic member, and a magnetic material. etc. can be applied in various ways.

A storage strap 180 is provided at the lower end of the mask body 110 . The storage strap 180 is configured so that when the filter replaceable mask 100 worn on the face is temporarily taken off for eating, it can be hung around the neck and stored without placing it on the table or the floor.

Therefore, the storage strap 180 is made of a material having elasticity, has a closed loop shape, and both ends can be changed to and combined in various positions as long as it is within a range that maintains a state bonded to one side of the mask body 110 .

Hereinafter, a detailed configuration of the filter replaceable mask 100 will be described with reference to the accompanying FIGS. 4 and 5 .

4 is an inner side perspective view showing the external configuration of the replaceable filter mask 100 according to the present invention, and in FIG. 5 , the filter 120 in the replaceable filter mask 100 according to the present invention is the mask body ( 110), an exploded perspective view of the inner side showing the separated state is shown.

As shown in the drawing, the filter exposing part 112 is perforated in the center of the filter replaceable mask 100, and the filter 120 is attached to the filter exposing part 112 while having a corresponding shape and is shielded.

In this case, the filter 120 may have a planar shape, or a central portion protruding backward in consideration of the user's face contour.

The filter exposed portion 112 of the mask body 110 is surrounded by the above-described wire 140 for adhesion, and an attachment member 130 is installed in the inner direction of the adhesion wire 140, and the filter An attachment member 130 is also installed on the edge of the 120 .

Therefore, when the filter 120 is moved to the vicinity of the filter exposure part 112 , the filter 120 can be attached to the mask body 110 by manpower.

In addition, the attachment member 130 is configured to simultaneously perform a function of blocking the inflow of polluted air as well as a function of coupling the filter 120 and the mask body 110 .

Hereinafter, a detailed structure of the attachment member 130 will be described with reference to the accompanying FIGS. 6 and 7 .

6 is a cross-sectional view of part "A" of FIG. 4 showing the structure of an embodiment of the attachment member 130, which is one component of the filter replaceable mask 100 according to the present invention, and in FIG. 7 is a cross-sectional view of the present invention A cross-sectional view of section “A” of FIG. 4 showing the structure of another embodiment of the attachment member 130 as one configuration in the filter-replaceable mask 100 is shown.

As shown in the drawing, an attachment member 130 is provided near the filter exposed portion 112 of the mask body 110 and at the edge of the filter 120 . The attachment members 130 work with each other to keep the filter 120 attached to the mask body 110, and if necessary, they are selectively separated by the user to discard and replace the filter 120. is possible

In addition, the attachment member 130 is designed so that air does not leak by minimizing a gap therebetween in a state in which they are attached to each other. That is, the attachment member 130 has protrusions 132 and grooves 134 formed on the surfaces facing each other, and the protrusions 132 and the grooves 134 have sizes and shapes corresponding to each other, so that the sealing force is improved when they are fitted together. configured to be

In addition, the attachment member 130 may be arranged so that the surfaces facing each other have an S pole and an N pole by applying a magnetic material, and as shown in FIG. 7 , a metal ring-shaped attachment member ( 130), and the attachment member 130 of the mask body 110 may be configured to be attached by manpower by applying a magnetic material.

In addition, a thin rubber magnet may be employed for the attachment member 130 .

The scope of the present invention is not limited to the embodiments illustrated above, and many other modifications based on the present invention will be possible for those skilled in the art within the technical scope as described above.

" 형상의 절제(切除)된 형태로 구성할 수도 있다.For example, in this embodiment of the present invention, the filter exposing part 112 is configured in the form of a hole in the center of the mask body 110, but as shown in FIG.

"It can also be configured in a restrained form.

At this time, the filter 120 may be configured to have a larger area than the filter exposed portion 112 so that it can be hung under the user's chin to perform a UV blocking function.

In addition, since the filter replacement mask 100 can replace only the filter 120, the mask body 110 can be used for a long period of time.
