Description

Filter replacement mask {Facial Mask with nose receiving space}

The present invention relates to a filter-replaceable mask, and more particularly, to provide a mask body and a filter replacement part on the inner surface of the mask body, and separate the breathing air from the nose and mouth by the filter replacement part so as to be inhaled or discharged It's about a mask for

In general, a mask is used to prevent pollen, dust, bacteria, etc. present in the air and entering the human body through breathing to prevent harm to the human body. In addition, the mask is also used for the purpose of preventing smoke, and the structure that mainly covers the mouth and nose at the same time is common.

The structure includes a filter plate body for filtering dust and the like and blocking the mouth, and a wearing strap formed on both sides of the filter plate body to be hung on the ear.

Of course, a mask for blocking only the nose has been developed in the prior art, and a mask having a valve formed on the nose part has also been developed.

However, the mask that covers the nose and mouth at the same time is stuffy in that it covers the nose and the mouth at the same time, moisture gets inside the mask, and the moisture discharged through the nose part has disadvantages such as blurring the glasses.

In addition, a nose mask that covers only the nose has been developed, but it has a disadvantage in that it is a structure that blocks or covers only the nose, so there is not enough space to breathe, which causes discomfort in breathing.

First, it should be noted that in the drawings, the same components or parts are denoted by the same reference numerals whenever possible. In addition, in describing the present invention, detailed descriptions of related well-known functions or configurations will be omitted so as not to obscure the gist of the present invention.

The filter-replaceable mask 100 according to an embodiment of the present invention includes a mask body 110 that covers the nose and mouth, and is attached to the inner surface of the mask body 110 to enable breathing while allowing fine dust or viruses. It consists of a filter replacement unit 120 having a filter for filtering and the like.

In this case, it is natural that a wearing strap that can be hung on the ear is formed on the mask body 110, or a fixing band for fixing it by winding it behind the head may be formed.

Blocking projections 120a, 120b, and 120c are formed on the edge of the filter replacement part 120 to prevent air from leaking to the outside of the nose and the outside of the mouth and to separate the nose and mouth. , The blocking protrusions 120a, 120b, and 120c may be formed of soft rubber or silicone, or may be formed of a material such as a sponge or cloth. The blocking projections (120a, 120b, 120c) are divided into sub-parts, the nose portion, that is, the nose portion blocking projection (120a) for preventing air from entering or exhausting above the nose when the mask is worn, the mouth portion, That is, when the mask is worn, the mouth block protrusion 120b is used to prevent air from entering or exhausting the lower part of the mouth, and the middle part is used to separate the nose part and the mouth part to prevent the air discharged from the mouth from going to the nose side. It is made of a blocking projection (120c).

A filter coupling hole 121 in which a filter is detachable is formed in the upper and lower portions of the filter replacement unit 120 . In this case, the upper portion of the filter replacement unit 120 corresponds to the nose portion, and the lower portion corresponds to the mouth portion.

It is preferable that a filter fitting groove 121a is formed around the edge of the filter coupling hole 121, which is a ring 130 having elasticity in which the filter used in the present invention is fused or adhered to the ring 130. This is because it is composed of the mask filter fabric 140 . The mask filter fabric 140 may be any material that can filter out fine dust, bacteria, or viruses.

In addition, the material of the ring 130 may be any metal or synthetic resin, but it should be a material having elasticity. This is because it must be able to fit into the filter fitting groove (121a) using the elasticity of the ring (130).

As such, when the ring 130 is elastically used, the replacement of the filter becomes very easy. In addition, if only a part of the filter can be replaced as in the present invention, the expensive mask filter fabric 140 can be used to a minimum, thereby reducing the manufacturing cost of the mask and making it possible to use the mask for a long time.

In addition, in the present invention, a mask attaching means is formed in the filter replacement part 120 so that it can be attached and detached to the inner surface of the mask body 110 . In this case, various means such as a button, a belt tape, a tick button, an adhesive, etc. can be used as a detachable means.

As described above, although the present invention has been described by way of limited embodiments, the present invention is not limited thereto, and it is described below with the technical idea of the present invention by those of ordinary skill in the art to which the present invention pertains. Various modifications and variations are possible within the scope of equivalents of the claims to be made.
