FIGURE 1 Figure 1 is an illustrative view of the present inventions uses. The present invention is an induced draft anti-fog system for goggles 10 and similar optical devices. The present invention could be utilized with goggles 12, helmets and face shields 14, optical devices 16 and ski goggles 18 that allows air to circulate through a hollow elastomeric conduit across the goggle lens 20 thereby defogging said lens 20. FIGURE 2 Figure 2 is a front perspective view of the present invention. The present invention is an induced draft anti-fog system for goggles 10 and similar optical devices having an air tight goggle 12 comprising a housing 32and lens 20 with an air intake port 24 incorporated into a hollow elastomeric air circulation conduit 22 with ends in conduit communication on opposing sides of the housing 32. The exhaust fan 26 has an on/off switch 28 in communication with two battery packs 30. When the fan 26 is in operation, air is drawn into the intake port 24 and circulated into the goggle 12, defogging the goggle lens 20 and circulated out of the fan 26. FIGURE 3 Figure 3 is a rear perspective view of the present invention. The present invention is an induced draft anti-fog system for goggles 10 and similar optical devices having an air tight goggle 12 comprising a housing 32and lens 20 with an air intake port 24 incorporated into a hollow elastomeric air circulation conduit 22 with ends in conduit communication with air apertures 34 on opposing sides of the housing 32. The exhaust fan 26 has an on/off switch 28 in communication with two battery packs 30. When the fan 26 is in operation, air is drawn into the intake port 24 and circulated into the goggle 12, defogging the goggle lens 20 and circulated out of the fan 26. FIGURE 4 Figure 4 is a frontal perspective view of the present invention. Shown is a front view of the present invention illustrating the air circulation 38 through the induced draft anti-fog system for goggles 10 and the hollow elastomeric circulation conduit 22. Air is drawn into the circulation conduit 22 through the intake port 24 by the exhaust fan 26 which is energized by the batteries 30 due to activation of the on/off switch 28. The air flow enters the housing 32 of the goggles 12 and passes of the interior surface of the lens 20 to prevent the fogging and condensation development thereof. The air returns into the circulation conduit 22 and is then expelled back into the ambient air by the exhaust fan 26. Shown is an optional barrier 36 disposed within the circulation conduit 22 to provide one-way directional air flow therethrough. FIGURE 5 Figure 5 is a rear perspective view of the present invention. Shown is a rear view of the present invention illustrating the air circulation 38 through the induced draft anti-fog system for goggles 10 and the hollow elastomeric circulation conduit 22. Air is drawn into the circulation conduit 22 through the intake port 24 by the exhaust fan 26 which is energized by the batteries 30 due to activation of the on/off switch 28. The air flow enters the housing 32 of the goggles 12 and passes of the interior surface of the lens 20 to prevent the fogging and condensation development thereof. The air returns into the circulation conduit 22 and is then expelled back into the ambient air by the exhaust fan 26. A hood 40 is provided for the exhaust fan 26 to protect it from damage from external entities. FIGURE 6 Figure 6 is a sectional view of the present invention. Shown is a sectional view of the induced draft anti-fog system for goggles 10 cut through the fan 26 and hollow air circulation conduit 22 to depict the air circulation 38 through the conduit 22 and the exhaust fan 26 during the air expulsion phase. FIGURE 7 Figure 7 is a sectional view of the present invention. Shown is a sectional view of the air circulation through the induced draft anti-fog system for goggles 10 cut through the air intake port 24 and circulation conduit 22 during the intake phase. Depicted is an optional filter 42 disposed within the air intake port 24 to restrict entry of dirt, debris and water into the system. FIGURE 8 Figure 8 is an additional element of the present invention. Shown is a rear view of the induced draft anti-fog system for goggles 10 having an additional elastic strap 44 with a plurality of loops 46, utilized as an optional attachment to the conduit 22 to allow the user to adjust the tightness of the device to one's face.
