When the inhalation path A is described in more detail, when the inhalation is performed, the valve plate 41 of the intake check valve 40 that closes the intake port 24 by the pressure is heard, and the outside air is exhaled through the gap. 23a). The external air flowing into the inhalation space (23a) is filtered through the filter assembly (30). The filtered foreign matter accumulates in the inspiration space 23a. The filtered external air flows into the respiratory space 11 through the communication section 23a and is sucked through the nose. At this time, the exhaust check valve 50 maintains a state in which the through-hole 61 is closed even when pressure is caused by breathing.

Similarly, when the exhalation path B is described in detail, when the exhalation is performed, the valve plate 51 of the exhaust check valve 50 that closes the through-hole 61 by the pressure is heard, and the breathing space 11 is opened through the gap. And the exhalation passing through the communication section 23c flows into the exhalation space 23b. The exhalation introduced into the exhalation space 23b is discharged to the outside through the exhaust port 25. At this time, the intake check valve 40 maintains the closed state of the intake port 24 even when pressure due to exhalation occurs.

The intake check valve 40 passes inhalation and does not pass exhalation, and impurities filtered by the filter assembly 30 are not released to the outside and are deposited in the inhalation space 23a.

The secondary dust can be prevented by trapping the filtered dust in the inhalation space (23a), and the exhalation exhaust check valve provided in the existing mask face can be formed inside the body (20) to make the nose cap (10) small. , When worn, the skin contact area of the face is narrowed, the amount of resorption of exhalation is reduced, and it is easy to wear and carry.

Also, do not inhale the exhalation (smell) discharged through the mouth through the nose.

In addition, it is possible to obtain and utilize various health care information by replacing the stopper with a bio-health care unit 70. The health care unit 70 has an advantage in that it can calculate the exact calorie consumption by detecting the actual breathing amount.

In addition, the body 20 is coupled so as to rotate on one side of the through-hole 12 of the nose cap 10, the wearer can adjust the rotational position. Various designs can be easily implemented by putting an exterior cover on the breathing apparatus.

Similarly, the breathing apparatus for blocking fine dust, which is a second preferred embodiment of the present invention, is a main body 20 and a stopper or a health care unit 70 assembled to a through hole 12 of a nose cap 10 as shown in FIG. 4. Can be combined by swapping left and right, so left- and right-handers can select and assemble.

Other configurations and operation procedures are the same as those of the first preferred embodiment of the present invention.

Likewise, in the third preferred embodiment of the present invention, the respiratory apparatus for blocking fine dust is equipped with a main body 20 at a through hole 12 of a nose cap 10, respectively, as shown in FIGS. 5 to 8.

The second cover 22 constituting the main body 20 is communicated to the communication section 23a, the communication pipe 82 protruding to the outside through the exhalation space 23b is projected, and a section is provided at the end of the communication pipe 82 The connector 80 is mounted. The oral connection pipe 80 is preferably made of a flexible material, and a corrugated pipe structure is applied for ease of use. It is preferable that the end of the section connecting pipe 80 is formed in a structure that is easy to hold in the mouth.

The operation process of the respiratory apparatus for blocking fine dust, which is a third preferred embodiment of the present invention configured as described above, is as follows.

As illustrated in FIG. 7, when a user inhales through the mouth while wearing a breathing apparatus, external air enters the respiratory system through the oral inhalation path C. If the inhalation path (C) is described in more detail, when the inhalation is performed, the valve plate 41 of the intake check valve 40 that closes the intake port 24 by the pressure is heard, and the outside air is exhaled through the gap. It flows into (23a). The external air flowing into the inhalation space (23a) is filtered through the filter assembly (30). The filtered foreign matter accumulates in the inspiration space 23a. The filtered external air flows through the communication section 23a and enters the oral connection tube 80 and is sucked through the mouth. At this time, the exhaust check valve 50 maintains a state in which the through-hole 61 is closed even when pressure is caused by breathing.

Similarly, if the oral exhalation route D is described in detail, when the exhalation is performed, the valve plate 51 of the exhaust check valve 50 that closes the through hole 61 by the pressure is heard, and the oral connection pipe ( 80) and the exhalation passing through the communication section 23c flows into the exhalation space 23b. The exhalation introduced into the exhalation space 23b is discharged to the outside through the exhaust port 25. At this time, the intake check valve 40 maintains the closed state of the intake port 24 even when pressure due to exhalation occurs.

The intake check valve 40 passes inhalation and does not pass exhalation, and impurities filtered by the filter assembly 30 are not released to the outside and are deposited in the inhalation space 23a.

It is also possible to selectively inhale and exhale through the mouth and nose. For example, it is possible to inhale through the mouth, exhalation through the nose, exhalation through the nose, and exhalation through the mouth to increase convenience of use.
