DETAILED DESCRIPTION OF THE INVENTION

[0019] Referring to FIGS. 1 to 5, a goggles and air filter combination in accordance with the invention comprises goggles 1, an air filter 2 and a strap 3 as discussed in detail below.

[0020] The air filter 2 is mounted a top of the goggles 1. The goggles 1 include a frame 11, an eyeglass 12 held by the frame 11, a container 13 on a top, and a bridge 14 configured to rest on the nose of a user. The eyeglass 12 is curve as shown (or flat) to tightly fit on the face of the user, so that a user may feel a degree of comfort because the goggles are tightly fitted on the face. The bridge 14 is made as small as possible so as to increase the user's field of view. The air filter 2 includes a housing 21 releasably disposed in the container 13 by snapping so that it is easy to replace components of the air filter 2 if such need arises. The air filter 2 further comprises a centrifugal fan 22 and a filter element 24 on a top of the centrifugal fan 22. The centrifugal fan 22 can draw external air through the filter element 24 which removes solid particulates such as dust, pollen, mold, and bacteria from the air. Further, the centrifugal fan 22 can move clean air from the filter element 24 to the eyeglass 12 so that the air can remove fog, moisture, etc. from the eyeglass 12. The housing 21 includes a first compartment 211 and a second compartment 212 with the centrifugal fan 22 disposed therein. The air filter 2 further comprises a power supply (e.g., rechargeable battery) 23 in the first compartment 211, and a printed circuit board (PCB) 25 disposed on a top of the power supply 23 and electrically connected to the centrifugal fan 22 and the power supply 23 respectively. The power supply 23 is configured to supply electricity to the centrifugal fan 22. A power socket (not shown), a push-button (not shown) and a power-on light (not shown) are provided the PCB 25. Detailed description of the centrifugal fan 22, the power supply 23, the PCB 25, the power socket, the push-button and the power-on light are omitted herein because they are known in the art.

[0021] The air filter 2 further comprises a cover 26 releasably mounted on the housing 21 with the PCB 25 directly disposed thereunder, an on/off switch 27 provided on a top of the cover 26, and an opening 28 through a front surface of the housing 21 to communicate with the second compartment 212 and the eyeglass 12 respectively.

[0022] The strap 3 has two ends attached to two clasps (not numbered) at two ends of the frame 11 respectively. Length of the strap 3 is adjustable and the clasps are known in the art.

[0023] 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.
