  • Publication number: 20230364448
    Abstract: In a facemask (100), atmospheric air is filtered by a disposable surgical mask (180) to form respirable air. The facemask (100) has a frame (150) formed with an interior cavity (151) for storing the respirable air to be breathed by the user. A thermoregulation unit (110) mounted to the frame (150) provides air conditioning to the respirable air by using a fan (421) to draw the respirable air from the cavity (151) to a heat exchanger (425) that contacts a thermoelectric module (410) to thermoelectrically transport heat to outside the frame (150), thereby cooling the drawn respirable air and condensing water vapor therein. The condensed water vapor is trapped by the heat exchanger (425). Cool and dry respirable air is released back to the cavity (151), thus providing thermal comfort to the user during breathing. A heat sink (432) contacted with the thermoelectric module (410) is used with a fan (431) to efficiently dissipate heat from the thermoelectric module (410) to outside the frame (150).
