Referring to fig. 3 and 5, the connection cover 40 is detachably connected to the connection protrusion 33 of the separation cover 30, and the connection cover 40 is provided with at least one opening 42 communicating with the first expiration region 32. The replacement filter 45 is placed inside the coupling cap 40 and covers the opening 332 of the coupling protrusion 33 of the separation cover 30.

Referring to fig. 2 and 6, the two first air valves 50 are one-way air valves and are respectively located on two opposite sides of the connecting protrusion 33 of the separating cover 30, the two first air valves 50 penetrate through the cover portion 11 of the outer garment layer 10 and the filter layer 20 and are in one-way communication with the separating cover 30 between the first exhalation module 32 and the outside of the outer garment layer 10, so that the air in the first exhalation module 32 can be exhausted through the two first air valves 50, and the air outside the outer garment layer 10 cannot enter the first exhalation module 32 through the two first air valves 50.

The two second air valves 60 are one-way air valves and located above the two first air valves 50, the two second air valves 60 are disposed through the mask portion 11 of the outer coat layer 10 and the filter layer 20, and are in one-way communication with the second expiration area 34 and the outside of the outer coat layer 10, so that the air in the second expiration area 34 can be exhausted through the two second air valves 60, and the air outside the outer coat layer 10 cannot enter the second expiration area 34 through the first air valves 50.

Preferably, each first air valve 50 comprises a first valve seat 51, a first valve cover 53, and a first valve plate 52, the first valve seat 51 and the first valve cover 53 are connected to each other, the first valve plate 51 is disposed between the first valve seat 51 and the first valve cover 53, and connects the first expiration area 32 and the outside of the outer coat layer 10 in a single direction; each second air valve 60 comprises a second valve seat 61, a second valve cover 63, and a second valve sheet 62, wherein the second valve seat 61 and the second valve cover 63 are connected with each other, the second valve sheet 62 is disposed between the second valve seat 61 and the second valve cover 63, and is in one-way communication with the second exhalation area 34 and the outside of the garment layer 10.

Referring to fig. 1 and 4, preferably, the oronasal respiratory separation filter mask further includes a nose bridge piece 70, the nose bridge piece 70 is combined on the outer side of the mask body 11 of the outer coat layer 10, so that the shape of the outer coat layer 10 can be fixed by the nose bridge piece 70, and the outer coat layer 10 is more fit to the bridge of the nose of the user.

Referring to fig. 5 to 7, when wearing, the mask body 11 of the outer coat layer 10 covers the mouth and nose of a human face, and the separating mask 30 covers the mouth, so that the mouth is located in the first expiration zone 32, the nose is located in the second expiration zone 34, the two ear hanging parts 135 of the outer coat layer 10 are hung on the left and right ears respectively, and the two connecting pieces 13 are pulled to the back of the skull to be buckled.

Since the mouth and nose of the user are located in the first exhaling zone 32 and the second exhaling zone 34 respectively, when the user inhales on the nose, air can be filtered by the outer coat layer 10 through the filter layer 20 and enter the second exhaling zone 34, since the two second air valves 60 are one-way valves, when the user inhales on the nose, air cannot enter the second exhaling zone 34 through the two second air valves 60, so that the air entering the second exhaling zone 34 is filtered through the filter layer 20, and the air exhaled by the nose can be rapidly exhausted from the second exhaling zone 34 through the two second air valves 60; when the mouth inhales, the air can be filtered by the replacing filter 45 and enter the first expiration area 32, because the two first air valves 50 are one-way valves, the air can not enter the first expiration area 32 through the two first air valves 50 during inhaling, so that the air entering the first expiration area 32 is filtered by the replacing filter 45, and when the mouth exhales, the air can be rapidly discharged out of the first expiration area 32 through the two first air valves 50.

Therefore, the separation cover 30 can be used to separate the breathing space of the nose and the mouth of the user, so as to prevent the carbon dioxide exhaled by the mouth from being inhaled during the inhalation of the nose, and the two first air valves 50 and the two second air valves 60 can be used to improve the efficiency of carbon dioxide discharge.

In addition, the replacement filter 45 can be replaced by simply removing the connection cover 40, and the replacement filter 45 can be quickly replaced when the replacement filter 45 is affected by moisture or contaminated.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with the preferred embodiment, it is not limited to the present invention, and any skilled person can make modifications or changes equivalent to the equivalent embodiment without departing from the scope of the present invention, but all the technical matters of the present invention are within the scope of the present invention.
