Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0007] FIG. 1 is a schematic view of a combination air filter and protective mask according to a first preferred embodiment of the invention;

[0008] FIG. 2 schematically depicts the full face mask; and

[0009] FIG. 3 is a schematic view of a combination air filter and protective mask according to a second preferred embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Referring to FIGS. 1 to 2, a combination air filter and protective mask in accordance with a first preferred embodiment of the invention comprises an air pump 1, a first line 2A having a first end connected to the air pump 1, an air filter 3 connected to a second end of the first line 2A, a second line 2B having a first end connected to the air filter 3, a connecter 4 connected to a second end of the second line 2B, a third line 2C having a first end connected to the connector 4, and a full face mask 5 connected to a second end of the third line 2C.

[0011] The air pump 2 can be activated if a person wearing the full face mask 5 needs a great volume of fresh air. Then the air flows from the air pump 2 to a space defined between the full face mask 5 and the face of the person through the first line 2A, the air filter 3 which removes solid particulates such as dust, pollen, mold, and bacteria from the air to generate fresh air, the second line 2B, the connector 4, and the third line 2C.

[0012] As shown in FIG. 2 specifically, inside of the full face mask 5 is filled with fresh air (indicated by arrows).

[0013] Referring to FIG. 3, a combination air filter and protective mask in accordance with a second preferred embodiment of the invention is shown. The characteristics of the second preferred embodiment are substantially the same as that of the first preferred embodiment except the following: an oxygen tank 6 as a replacement of both the air pump 1 and the air filter 3, a second line 2B having a first end connected to the oxygen tank 6, a connecter 4 connected to a second end of the second line 2B, a third line 2C having a first end connected to the connector 4, and a full face mask 5 connected to a second end of the third line 2C. The oxygen tank 6 can be opened if a person wearing the full face mask 5 needs a great volume of fresh air. Then the fresh air flows from the oxygen tank 6 to a space defined between the full face mask 5 and the face of the person through the second line 2B, the connector 4, and the third line 2C.

[0014] While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
