In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "indirectly connected" . Also, when an element is referred to as " comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, a nasal mask inserted into a nostril according to an embodiment of the present invention includes a fixing protrusion 100,

housings

11 and 12, an air inlet 110a, an outer opening and closing member 112, (Not shown), a middle opening and closing member 114, and an air outlet 130.

The fixing protrusions 100 may have a predetermined length to be inserted into the nostrils of the user and may include a plurality of curved protrusions 121 formed on the outer circumferential surface of the axis about the axis thereof and coaxially along the lengthwise direction.

Each curved projection 121 extends radially about the axis of the fixing protrusion 100 and is curved in a direction opposite to the direction of insertion into the nostril so that when the curved projection 121 is inserted into the nostril, But it is possible to restrict the movement in the direction in which the fixing protrusion 100 is separated from the nostril.

In other words, when the fixing protrusion 100 is inserted into the nostril of the user, it is easily inserted, but unintentional detachment due to vibration or user's exhalation is prevented.

The fixing protrusion 100 may be formed at a lower end thereof with a fixing portion 120 which is fixedly coupled to a mounting hole 101 of a side housing 12 to be described later.

The mounting hole 101 has a small diameter and a small diameter portion (not shown) smaller than the diameter of the fixing protrusion 100 of the fixing portion 120 is fixed to the

mounting hole

101, 101 so as not to be separated.

More specifically, when the

housings

11 and 12 are assembled with the split structure, semicircular grooves are formed in the divided

housings

11 and 12, respectively, and the

housings

11 and 12 are coupled, The semicircular holes can be joined together to form one circle, so that the fixing protrusions 100 can be coupled while being inserted.

The

housings

11 and 12 can be divided into a side housing 12 and a center housing 11. [

That is, the side housing 12 and the central housing 11 having respective internal spaces can be formed to communicate with each other.

At this time, an air inlet 110a may be formed in each of the outer ends of the side housing 12 so that air is sucked in.

An air discharge port 130 may be formed at the lower end of the central housing 11 so as to communicate with a space through which air can flow in the

respective housings

11 and 12.

The air introduced through the air inlet 110a formed at the outer ends of the side housings 12 passes through the filter member 111 to be filtered. Here, each of the filter members 111 is formed to be engageable with or detachable from each of the side housings 12, thereby facilitating the replacement operation when the filter member is replaced.

When the air passes through the respective air inlets 110a and flows into the central housing 11 along the longitudinal direction of the

housings

11 and 12,

The side flow path 110b constituting the inner space of the side housing 12 gradually decreases in flow area toward the center housing 11 and may be inclined upward toward the mounting hole 101. [

The air passing through the side housing 12 is guided upward by the side flow path 110b and flows smoothly toward the mounting hole 101 located on the upper side after exiting the side flow hole 110c. .

Each end of the side housing 12 in which the air intake port 110a is located is defined as the outer side and the end of the side housing 12 on the side of the central housing 11 along the longitudinal direction of the

housings

11 and 12 passes through the air intake port 110a Is defined as inner.

A pair of outer openable and closable members 112 may be installed in the respective side housings 12 at positions close to the respective air intake openings 110a.

The outer opening and closing member 112 may be installed so as to be close to the respective air intake openings 110a and open only to the inside along the longitudinal direction of the

housings

11 and 12. [

In other words, the outer opening / closing member 112 functions to pass only the air sucked from the air inlet 110a, and to block the air flowing from the inside to the outside of the

housings

11 and 12. The principle that the outer openable and closable member 112 guides the air flow in one direction is due to the pressure difference inside the intermediate opening and closing member 114 and the central housing 11 described later, and a detailed description will be given later.

At this time, the outer stopper 113 may be formed so as to limit the amount of opening of the outer opening and closing member 112. The outer stopper 113 is formed to extend transversely to the air flow direction inside the side housing 12 to limit the opening amount by contacting the outer stopper 113 in the process of opening the outer opening and closing member 112 Can be performed.

The intermediate opening and closing member 114 is formed inside the central housing 11 and can be installed to be opened only in a direction approaching each other.

The middle opening and closing member 114 functions to guide the air discharged when the user exhales through the air outlet 130 formed at the lower end of the central housing 11. At this time, the intermediate opening and closing member 114 may be installed to open or close the intermediate flow hole 110d formed to be inclined upward.

Further, an intermediate stopper 115 for limiting the amount of opening of the intermediate opening and closing member 114 may be formed.

The intermediate stopper 115 is interposed between the intermediate openable and closable members 114 and is formed at a position where the intermediate openable and closable members 114 are in contact with each other at the same time so as to limit the opening amount of the intermediate openable and closable member 114.

The intermediate stopper 115 may be formed across the central housing 11 in a direction substantially perpendicular to the air flow direction.

The operation of the nasal mask inserted into the nostril according to an embodiment of the present invention as described above will be described below.

Fig. 2 shows a state at the time of inhalation of Fig. 1, and Fig. 3 shows a state at the time of exhalation of Fig.

Referring to FIG. 2, air is sucked through the air inlet 110a of each side housing 12 when the user exhales from the nose.

At this time, the sucked air passes through the respective filter members 111, and foreign substances contained in the air are filtered.

Thereafter, the outer opening / closing member 112 of the side housing 12 is opened inward due to the pressing force of the intake air.

The air flowing through the outer opening and closing member 112 is raised through the adjacent mounting hole 101 and the intermediate opening and closing member 114 is closed by the negative pressure of the side housing 12. [

As a result, the intake air passes through the mounting hole 101 and flows through the vertical flow passage formed inside the fixing protrusion 100, thereby supplying the air filtered by the user to the nostrils of the user.

As shown in FIG. 2, at the time of exhalation, air is discharged through the vertical flow passage formed inside the fixing protrusion 100.

At this time, the partially open outer shutoff member 112 is closed due to the downward pressure of the air and the middle shutoff member 114 of the central housing 11 is opened, .

And is discharged to the outside through the air outlet 130 formed at the lower end of the central housing 11, thereby guiding a smooth air flow.

Therefore, when the user inhales in the state where the nasal mask 10 according to the present embodiment is worn, the foreign substance of the air sucked through the air inlets 110a is sucked in the filtered state, The air can be discharged to the outside through the air outlet 130 separately provided, so that not only the smooth breathing is possible but also the air pressure is distributed at the time of inhaling and exhalation so that the state fixed to the user's nostril can be stably maintained.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
