Abstract
The sterilization mask with UVC reflective chamber includes a chamber with reflective liner, through which inhaled and exhaled air passes. The reflective chamber is also referred to as a sterilization chamber. Using a reflective chamber ensures each photon of UVC light has a long life, thus dissipating slowly. Increasing the life of the UVC photons decreases the quantity of photons that must be created. Thus, less power is required to achieve the sterilization. Sterilization is defined as a 6-log reduction (99.9999%) of various microbes including viruses, bacteria, and spores. Heat generated by the UVC lights is carried away from the mask by a heat transfer fluid, the heat dissipated away from the user.
Claims18
A portable air sterilization device for a user, the device passing inhaled air and exhaled air through a sterilization chamber, the device comprising:
- a chamber;
- the chamber including a mask connection point and an atmospheric connection point;
- the inhaled air and the exhaled air passing in and out of the chamber via the mask connection point;
- atmospheric air passing in and out of the chamber via the atmospheric connection point;
- one or more UVC light sources creating UVC light within the chamber;
- the UVC light bouncing around an inside of the chamber, thereby sterilizing the inhaled air and the exhaled air;
- a heat exchanger module;
- the heat exchanger module removing heat generated by the one or more UVC light sources;
- the heat transferred between the one or more UVC light sources and the heat exchanger module by a heat-transfer fluid, the heat-transfer fluid being a liquid;
- whereby the portable air sterilization device is able to efficiently sterilize air by maximizing battery life of the UVC light and maximizing life of the UVC light and its photons;
- wherein the heat exchanger module further comprises a heat-transfer fluid flow path between an external metal shell and an internal metal shell, the external metal shell allowing dissipation of heat to ambient air, the internal metal shell adjoining a layer of insulation to prevent heat absorption.

A portable, wearable, UVC sterilizing mask comprising:
- a sterilization chamber;
- the sterilization chamber including an inner wall;
- the inner wall separating the sterilization chamber into a single-direction inhalation flow path and a single-direction exhalation flow path;
- an inhalation assistance fan;
- the inhalation assistance fan placed at an inlet to the single-direction inhalation flow path;
- the inhalation assistance fan operating during both inhalation and exhalation;
- one or more UVC emitters radiating UVC light into the sterilization chamber;
- the one or more UVC emitters having an intensity;
- the intensity automatically adjusted based on an airflow through the sterilization chamber, with increased airflow increasing intensity, and decreased airflow decreasing intensity;
- a heat exchanger module;
- the heat exchanger module removing heat generated by the one or more UVC emitters;
- the heat transferred between the one or more UVC emitters and the heat exchanger module by a heat-transfer fluid, the heat-transfer fluid being a liquid;
- whereby the portable, wearable, UVC sterilizing mask minimizes power use while sterilizing both incoming and outgoing air;
- wherein the heat exchanger module further comprises:
- a heat-transfer fluid flow path between an external metal shell and an internal metal shell, the external metal shell allowing dissipation of heat to ambient air, the internal metal shell adjoining a layer of insulation to prevent heat absorption.
