Single-pair earphone sterilizer with germicidal light
Apparatus and methods include a single-pair earphone sterilize with germicidal light. Embodiments include a housing and a germicidal light source. The apparatus may include circuitry, such as power, to support the germicidal light source and a divider to shield the circuitry from the germicidal light source. The apparatus may also include attachment portions to position and maintain earphones in a position relative to the germicidal light source.
1. An apparatus for cleaning earphones, comprising:
a housing having a first housing portion and second housing portion, the housing having an open configuration and a closed configuration;
a divider in the housing, the housing and divider defining a first compartment and a second compartment within the housing in the closed configuration;
a germicidal light source in the first compartment;
a light shield configured to cover the germicidal light source relative to an opening of the housing when the housing is in the open configuration and provide light access through apertures in the light shield at opposing sides of the light shield; and
support circuitry coupled to the germicidal light source, the support circuitry arranged in the second compartment such that the support circuitry is shielded from light from the germicidal light source by the divider.
2. The apparatus of claim 1 , further comprising a first and a second attachment portion, each attachment portion positioned to support an earbud and maintain the earbud in a desired orientation relative to the germicidal light source.
3. The apparatus of claim 2 , wherein the first and second attachment portions each comprise a clamp coupled to the divider, the clamp defining two deformable arms to frictionally engage an earbud positioned therebetween.
4. The apparatus of claim 3 , wherein the first and second attachment portions are rotatable about an axis perpendicular to the divider to vary an incident angle of light emitted by the germicidal light source onto an attached earbud.
5. The apparatus of claim 4 , wherein the germicidal light source is an elongate light source and the first and second attachment portions are on opposing sides of the light source.
6. The apparatus of claim 5 , further comprising a timer configured to shut off light from the germicidal light source after a predetermined period of time after the germicidal light source is initially illuminated.
7. The apparatus of claim 6 , further comprising a switch within the second compartment and accessible by a projection on the housing attached within the first compartment and extendable through the divider to contact the switch when the housing is in the closed configuration.
8. The apparatus of claim 7 , wherein the light shield covering the germicidal light source is positioned on an opposite side of the germicidal light source from the divider.
9. The apparatus of claim 8 , further comprising a manual switch on an exterior surface of the housing.
10. The apparatus of claim 9 , wherein the housing comprises an aperture in the closed configuration to pass a cord of the earbud during use.
11. The apparatus of claim 2 , further comprising a safety switch configured to prevent the germicidal light source from illuminating when the housing is in the open configuration.
