1. A charging case for earbuds comprising:
a box body having a base, a front wall, and a rear wall defining an inner volume of the box body, top of the box body is open;
a cover coupled to the box body, the cover configured to switch between an open state and a closed state,
one or more charging docks in the box body for mounting one or more earbuds for charging,
a plurality of UV LEDs, wherein at least one UV LED is disposed in the box body, and at least one UV LED is disposed in the cover, wherein the plurality of UV LEDs are configured to irradiate/sterilize an inner surface of the charging case uniformly, wherein the plurality of UV LEDs are also disposed within each of the one or more charging docks for uniformly irradiating the one or more earbuds, wherein an inner surface of the cover, the box body, and the one or more charging docks has a layer of reflective coating configured to enhance sterilizing efficiency of UV radiations;
a sensor for detecting the receiving of the one or more earbuds on the one or more charging docks, the sensor also configured to detect opening and closing of the cover; and
a control unit operably coupled to the at least one UV LED, the sensor, and a charging circuitry, the charging circuitry configured to charge the one or more earbuds, the control unit configured to:
receive a first signal from the sensor indicating the mounting of the at least one earbud on the at least one charging dock,
receive a second signal from the sensor indicating the closing of the cover,
upon receiving the first signal and the second signal, turning on the plurality of UV LEDs on for a predetermined duration,
wherein the control unit further comprises a timing circuitry configured to receive a duration for which the plurality of UV LEDs are turned on.
