3, because the present invention causes guiding turnover air fully, required sealing mechanism is reduced into nostril plug and the peripheral ringlet that contacts in nostril, therefore the user does not have the sense of discomfort that the preferable sealing ring that breathing circuit filter causes of general prior art sealing is close to facial skin when of the present invention wearing, and the sultry damp of sealing cover skin in sealing ring, eliminate the discomfort that friction produced simultaneously fully because of sealing ring.

4, because the present invention is the situation that allows the user cover with nasal respiration and no-trump mouth, therefore the user can wear when of the present invention and other people talk freely, and general often must be in the traffic control personnel that work in the serious environment of air pollution even can use the present invention on one side, on one side the work doing to direct traffic with whistle.

5, by adjusting this soft conduit 10, can make the present invention be applicable to the user of the various different shapes of face.

6, because body 2 is arranged at the cheek both sides, though cheek can be covered fully, but still can be by the maintaining a certain distance between body 2 and cheek against making of this extension 213, the cool ambient air that the user sucks still can be passed through the cheek that is covered, and the feeling of oppression and heat of cheek is minimized.

7, because this extension 213 is to contact at face to have the position, acupoint of producing refreshing effect to the mind, as has a cheekbone glue cave that beautifying face, treatment faceache and eye fatigue etc. act on, and have treatment nasal obstruction, nose is bleeding, acute and chronic rhinitis and the positions such as fragrant cave of the effect of refreshing oneself, allow the user wear when of the present invention except can breathing clean air, also can obtain the benefit of acupoint massage.

8, according to theory analysis, this filter course 23 pressure loss that flows through air air effective with it that cause sees through square being inversely proportional to of area.Be different from the little sensation of asphyxia that causes of filter course 23 areas of the air filtering mask of general prior art sealing, filter course 23 of the present invention is because there is bigger effective air to see through area, so the user does not have sensation of asphyxia when air-breathing.The pressure loss (for example nasal obstruction) that generally is attached to the nose breathing channel is when reaching 16mmHg, and the normal person has sensation of asphyxia and dehisces air-breathingly, and the effect of breathing full filter this moment just loses fully.The present invention the experiment proved that when filter course 23 thickness that use reach 1mm the pressure loss that causes together with breath gas air channel is 11mmHg only, in the sustainable scope of common people.Have the thickness that presss from both sides the filter course 23 of one deck activated carbon fiber cloth in the two-layer nonwoven and be 0.56mm and generally uses, the pressure loss that is caused is about 6mmHg, much smaller than to greatest extent, allows the user can be air-breathing easily.

9, the side owing to this body 2 slightly is

Shape, promptly the degree of depth of this second air chamber 204 is that the direction that a side direction by adjacent this first air chamber 203 differs from this first air chamber 203 reduces gradually, this is the design behind flow dynamics analysis, can make the air mass flow that filter course 23 enters this second air chamber 204 of flowing through be evenly distributed, except filter course 23 of the same area is had the minimum loss of air pressur, can also make full use of all areas of filter course 23, when the new filter course 23 of displacement, be unlikely to cause the waste of goods and materials.

10, the side owing to this body 2 slightly is

Shape makes it the thinnest near the ears place, for the locomotive knight user who wears all cover safety cap, can also use the present invention, and then ensure that it is healthy.

11, after the present invention added imitative mouth mask overcoat, it was the same just like wearing general mouth mask to make its outward appearance, gets rid of the repulsion sense because of the user that indecency outward appearance caused who uses nasal cannula assembly 1 fully.
