DESCRIPTION
DESC:FIELD OF THE INVENTION


In general the present invention relates to a switch for charging of electronic devices. More particularly, the present invention relates to a smart switch for charging of the electronic devices and having a time selector switch for selecting a plurality of charging run times.


BACKGROUND OF THE INVENTION


In today's digital world of portable electronic devices, people have one or more devices, such as smart phones, portable music players, electronic reading tablets to name a few. In order to keep these devices powered, it is necessary to charge them at regular intervals through the use of a power adapter that plugs into a wall receptacle or through a cable which can be coupled to a computer. In order to charge these devices, preferably manual sockets are used to plug in the charger.


Further, electronic sockets which are present in the prior art, are manually operated and can perform only two operations that is “ON” and “OFF”. Thus not giving any option to set/control desirable charging time.


Additionally, overcharging any electronic device can cause harm to the energy storing unit of the device as there is not any real time notifier such as light emitting diode (LED) indicator and Touchscreen display, which is coupled with the existing sockets present in the state of art.


Lastly, the existing wall sockets are highly manual and does not support interface for direct universal serial bus (USB) charging. Many portable electronic devices nowadays comes with a USB plug so that the can be attached to the computer/laptop for charging their battery. But the traditional sockets present does not allow these plugs to get into use as the socket can only accommodate Pin plugs


As such, a socket is needed which could cover all limitations which are mentioned above.


CN203260856 - This invention discloses a recessed power socket with USB charging interfaces comprises a socket body with conventional power jacks and further comprises USB charging interfaces, a transformer and a charging circuit board, wherein the USB charging interfaces are arranged on a socket body panel, the transformer and the charging circuit board are arranged in the socket body, a power input end of the transformer is electrically connected in parallel with power input ends of the conventional power jacks, and the transformer, the charging circuit board and the USB charging interfaces are electrically connected in sequence. However, the invention does not provide any feedback, is highly manual, and provides no power backup.


CN203039202 - The utility model relates to a USB charging multi-interface socket containing timing setting. The socket comprises a power switch, a power-on indicating lamp, two-pin jacks, and three-pin jacks. The two-pin jacks and the three-pin jacks are disposed in a housing. The socket also comprises LED prompting lamps, USB interfaces, a charging module, and a timing switch module equipped with displays and time-adjusting buttons. The timing switch module and the charging module are disposed in the rectangular housing. Multiple two-pin jacks and multiple three-pin jacks are disposed on the top end face and the bottom end face of the panel of the housing, respectively. The power switch and the power-on indicating lamp are disposed on the left end face of the panel of the rectangular housing, while the displays, the time-adjusting buttons, and the LED prompting lamps are disposed on the right end face of the panel of the rectangular housing. Multiple USB interfaces are arranged between the multiple two-pin jacks and the multiple three-pin jacks. The socket has characteristics that the socket may charge cell phones, digital products, and electronic products equipped with USB interfaces in a timing manner according to charging time required by an individual while normally satisfying a function of a 220V power socket, and that the socket has a charge completion automatic prompting function in order to provide convenience for users. However, the invention does not provide multi-select timer option.


WO2000002218 – The invention discloses a timer unit includes: input pin connectors for electrically connecting the unit to a domestic power socket; an electrical outlet for connecting an appliance thereto; switch means for electrically connecting the input pins to the outlet of said unit; and count-down timer means operable to count down for a predetermined time period and after the predetermined time period to operate the switch means to electrically isolate said input pin connectors from said outlet. A reset mechanism prevents inadvertent electrical reconnection of an appliance in the event of a power loss and restoration to the timer unit. However, the invention does not provide multi-select timer option.
