The purified air is introduced into the user's respiratory tract according to the forced flow. Additionally, when the user exhales, the exhaled breath is forcibly discharged through the outlet 564 along the forced flow.

That is, there is a forced flow of air from the inlet 538 of the mask body 500 along the outlet 564, and the user's respirator is located in the middle of this forced flow, so when the user breathes in, the forced air flows in. It becomes relaxed, and when the user exhales, the exhaled breath is discharged along the forced flow.

Accordingly, when following the present invention, comfortable breathing can be achieved. In other words, with the help of the forced flow of air, it becomes easier to breathe in and out. In particular, carbon dioxide contained in the exhaled breath can be immediately released, making breathing more comfortable.

The pressure of the air supplied to the mask body 500 by the purified air supply means 200 can be adjusted according to the amount of exercise the user exercises. In this case, the optimal forced flow pressure can be achieved depending on the state of breathing according to the user's amount of exercise, etc.

This can be achieved by automatically adjusting the pressure of the air supplied to the mask body 500 through feedback control using a breathing sensor, but it is also possible to present several blowing pressures and allow the user to select the blowing pressure themselves.

For example, it can be set to 1st stage for static movement, 2nd stage for walking, etc., and 3rd stage for running, so that the blowing pressure can be adjusted for each stage.

According to the present invention, as shown in FIG. 4, the air supplied to the space (S) through the inlet 538 of the inlet 530 flows in the direction (T) crossing the user's face. It is desirable to do so.

The inlet 538 of the inlet 530 forms a flow field in a direction crossing the user's face, so that the air supplied to the space S through the inlet 538 crosses the user's face. It flows in the same direction.

Accordingly, as described above, the discharge port 564 of the discharge portion 560 is the inlet 538 relative to the transverse direction with respect to the user's face when the mask body 500 is worn by the user. It is formed toward the rear of the mask body 500 in a direction crossing the face of the user wearing the mask body 500, as a place beyond the user's respiratory tract.

In this case, the discharge port 564 of the discharge portion 560 is vertically directed toward the rear of the mask body 500 with respect to the direction crossing the face of the user wearing the mask body 500, or toward the user's face. The mask body 500 is formed at an acute angle toward the user's cheek 83 with respect to the vertical toward the back of the mask body 500 with respect to the direction crossing the face, or the mask body 500 is formed with respect to the direction crossing the user's face. It may be formed at an acute angle outward of the user's cheek 83 with respect to the vertical toward the rear.

Figure 7 (a) shows that the outlet 564 is formed in a direction perpendicular (R) toward the rear of the mask body in the direction (T) crossing the face of the user wearing the mask body 500.
