[0009] FIG. 1 of the drawings is a front view of a user's face with a protective mask covering the user's face;

[0010] FIG. 2 of the drawings is a side view of components of the present invention in accordance with a first embodiment of the invention;

[0011] FIG. 3 of the drawings is a side view of components of the present invention in accordance with a second embodiment of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] As shown in FIG. 1 a protective mask according to the present invention has a mask element 1 covering the user's face, and in particular its part containing a user's nose and a user's mouth.

[0013] In accordance with a first embodiment of the present invention shown in this FIG. 1 the protective mask further has a pipe 2 extending from a central area of the mask element 1 over a user's shoulder. The pipe 2 is connected to a ventilator or fan 3 which supplies an outside air and is operated by a motor 4 that can be battery-chargeable. It further has a filter 5 which receives the air from the ventilator 3, cleans this air and supplies the clean air into the space between the mask element 1 and the user's face, so that the user inhales the filtered clean air only.

[0014] In accordance with a second embodiment of the present invention shown in FIG. 2 the protective mask further has a mask element 1 which is connected by a pipe 6 with a tank of a cylinder 7 with a clean air which is pressurized in the tank or the cylinder. When the tank or the cylinder 7 is opened by a user for example by a faucet, the clean pressurized air flows from it under pressure from it into the space between the mask element 1 and the user's face, so that the user inhales the clean air only.

[0015] It is of course possible that the clean air is not pressurized in the tank or the cylinder 7, in which case a not shown pump can be provided to pump the clean air from the tank or the cylinder 7 into the space between the mask element 1 and the user's face.

[0016] The tank or the cylinder 7 can be of a relatively small size and carried by a user. On the other hand the tank or the cylinder 7 can be of a significant size and can be stationary located in medical offices, hospitals, etc. In this case it can be used not by a single person, but by many people.

[0017] The novel features of the present invention are defined in the appended claims.
