Abstract

A touch-switchable USB charging receptacle includes a rectifying and transforming circuit connected to a public power supply for converting AC power into DC power and supplying the latter to DC devices, such as mobile phones, MP3 players, video games, personal digital assistants, etc.; a power supply connector and an illuminating indicator module electrically connected to the rectifying and transforming circuit to obtain power supply; an integrally formed cover plate isolating the rectifying and transforming circuit, the power supply connector and the illuminating indicator module from external environment; and a touch switch located behind the cover plate and electrically connected to the rectifying and transforming circuit for controlling a power supply state of the latter. The illuminating indicator module emits indicating light, which is visible via a light-pervious indicator provided on the cover plate. Therefore, the cover plate is not only water-retardant but also capable of indicating a power supply state.

Claims

1. A touch-switchable USB charging receptacle, comprising a cover plate, an illuminating indicator module, a power supply module, and a switch module;

the power supply module including at least one rectifying and transforming circuit, a power supply control circuit, and at least one power supply connector;

the rectifying and transforming circuit being electrically connected to an AC public power supply for rectifying and transforming the AC power supply into DC power supply and then supplying the converted DC power supply to the power supply control circuit, the switch module, and the at least one power supply connector; and

the power supply control circuit including a timer and being capable of controlling a power supply state, so as to control the state of power supply to the at least one power supply connector;

the cover plate being assembled to an outer side of a recess formed on a wall, and being formed on a front face with at least a display zone, a power supply connection opening, and a touch zone;

the display zone being provided therein with at least a light-pervious indicator, via which indicating light emitted from the illuminating indicator module is always visible on the front face of the cover plate to indicate a power supply state and allow a user to conveniently recognize the position of the USB charging receptacle; and

the power supply connection opening being aligned and engaged with the at least one power supply connector;

the switch module being assembled to and located within the touch zone and being connected to the power supply control circuit, so that a user can control and change the power supply state to on or off by touching the touch zone to actuate the switch module; and

the illuminating indicator module being assembled to behind the display zone and including at least one light emitting unit.

2. The touch-switchable USB charging receptacle as claimed in claim 1, wherein the power supply module includes a first and a second rectifying and transforming circuit that are independent of each other;

the first rectifying and transforming circuit converting the AC power supply into DC power supply and supplying the converted DC power to the power supply control circuit, which is electrically connected to the illuminating indicator module;

the second rectifying and transforming circuit also converting the AC power supply into DC power supply, and the converted DC power supply independently serving as a power output for use;

the second rectifying and transforming circuit being electrically connected to the at least one power supply connector, and the power supply control circuit controlling the state of power supply from the second rectifying and transforming circuit to the at least one power supply connector.

3. The touch-switchable USB charging receptacle as claimed in claim 1, wherein the at least one power supply connector is connected to a feedback controller;

the feedback controller being capable of detecting whether an object being charged has been fully charged, and sending a power supply stop signal to the power supply control circuit when the object is fully charged.

4. The touch-switchable USB charging receptacle as claimed in claim 1, wherein the switch module is in the form of a touch switch button and located behind the touch zone of the cover plate to isolate from an external environment outside the cover plate.

5. The touch-switchable USB charging receptacle as claimed in claim 1, wherein the display zone and the touch zone overlap with each other.

6. The touch-switchable USB charging receptacle as claimed in claim 1, wherein the indicator is in the form of a light-pervious groove sunken from a rear face of the cover plate.

7. The touch-switchable USB charging receptacle as claimed in claim 5, wherein the light-pervious groove is designed as a power sign.

8. The touch-switchable USB charging receptacle as claimed in claim 1, wherein the at least one power supply connector is a USB connector.

9. The touch-switchable USB charging receptacle as claimed in claim 1, wherein the light emitting unit includes at least one light-emitting diode (LED).
