At present, many families have their own yard and several electronic devices may be installed therein (an outdoor lighting apparatus, for example); however, it usually needs to utilize an extension line socket to extend from indoor power outlet to outdoor environment in order to provide electric power that the outdoor electronic device needs to use, hence the extension line socket applicable for outdoor environment is more and more comprehensively utilized. But, a general extension line socket may not be able to be fixedly positioned due to mobility of such outdoor electronic devices, or even the power line of the extension line socket may come loose; additionally, in rainy days, the problem of short circuit in the extension line socket could happen because rainwater may infiltrate, so a user may be dangerously exposed to the risk of injury caused by lethal electric shocks once the user touches the wet extension line socket.
Furthermore, a general extension line socket is not able to designate the duration of power supply, so the switch time of the electronic device can not be suitably controlled according to the user's demand; thus, in the premises of environment protection, such a general extension line socket can neither effectively save energies nor meet the requirement on environment protection.

An outdoor extension line socket enabling remote controlled timing power supply capable of achieving above-said objectives is disclosed, comprising a socket body and a remote controller body, in which the bottom of the socket body is formed as a tapered body for sticking the socket body into the ground. A socket is installed on one side of the socket body, and a display and a time adjustment button are installed on the top of the socket body; besides, a socket power control circuit is installed inside the socket body and an extension line plug extends from the socket body for input of alternating current (AC) power.

The socket body 1 can be stuck on the outdoor ground in order to provide the outdoor electronic device 3 with electric power required for operations, and the remote controller body 2 can be used to set and adjust the power supply time of the socket body 1 thereby configuring the operation time of the outdoor electronic device 3.
It should be noted that, as shown in FIG. 1A, the top of the socket body 1 is additionally installed with a cover 15 which is used to shelter the display 12 and the time adjustment button 13 to prevent outdoor rainwater from wetting the display 12 and the time adjustment button 13 which may otherwise cause failures in such components.
It should be noted that, as shown in FIG. 1A, the time adjustment button 13 on the socket body 1 allows the user to set the power supply time manually.
It should be noted that, as shown in FIG. 1A, the display 12 on the socket body 1 is used to display the designated power supply time, and the display 12 can be a seven-segment display or composed of light emitting diodes.
It should be noted that, as shown in FIG. 1B, the time adjustment wheel 21 on the remote controller body 2 can remotely set the power supply time and consists of two sets of time setting specification thereby allowing the user to switch the first switch control button 22 and the second switch control button 23 in order to apply a different time setting specification.
It should be noted that, as shown in FIG. 2, the socket power control circuit is used to designate the power supply time of the socket body 1, which consists of an AC power input module 171, a voltage reducing and voltage stabilizing filter module 172, a relay 173, a relay driving module 174, an AC power output module 175, a microprocessor 176, an oscillator 177, a time adjustment button input module 178, a display module 179, an RF decoder 180, a photo-sensor 181 and an RF signal receiving module 182, in which the microprocessor 176 is interfaced with the voltage reducing and voltage stabilizing filter module 172, the relay driving module 174, the oscillator 177, the time adjustment button input module 178, the display module 179, the RF decoder 180, the photo-sensor 181 and the RF signal receiving module 182.
It should be noted that, as shown in FIGS. 1A and 2, the AC power input module 171 inputs AC power via the extension line plug 14 of the socket body 1 and is interfaced with the voltage reducing and voltage stabilizing filter module 172, and the voltage reducing and voltage stabilizing filter module 172 is further interfaced with the microprocessor 176, in which the AC power input module 171 and the voltage reducing and voltage stabilizing filter module 172 are both used to provide electric power required for operations of the microprocessor 176.
It should be noted that, as shown in FIG. 2, the oscillator 177 and the RF signal receiving module 182 are responsible for selectively receiving a constant RF signal which is decoded by the RF decoder 180, and then the power supply time designated by the remote controller body 2 is thus acquired and inputted into the microprocessor 176 of the socket power control circuit. The microprocessor 176 then accordingly starts to count the designated power supply time and the relay driving module 174 is driven by the microprocessor 176 to control the conductivity in the relay 173 such that the AC power output module 175 outputs AC power by way of the socket 11. In addition, at the end of the designated power supply time counted by the microprocessor 176, the relay driving module 174 will be driven so as to control the break in the relay 173 thereby interrupting AC power outputted by the socket 11.
It should be noted that, as shown in FIG. 2, the microprocessor 176 displays the power supply time designated by the remote controller body 2 on the display 12 of the socket body 1 by means of the display module 179.
It should be noted that, as shown in FIG. 2, the time adjustment button input module 178 can input the power supply time specified by the user with the time adjustment wheel 21 to the microprocessor 176 of the socket power control circuit and the display 12 shows the specified power supply time.

It should be noted that, as shown in FIG. 3, the oscillator 245 and the RF encoder 246 convert the power supply time designated by the wheel signal input module 247 into an RF signal, and the microprocessor 244 drives the RF signal emitting module 248 so as to transfer the RF signal to the socket body 1.
Refer subsequently to FIG. 4, wherein a diagram for an embodiment of the outdoor extension line socket enabling remote controlled timing power supply according to the present invention is shown. It can be seen from the Figure that the socket body 1 is stuck with a plug 31 of an outdoor electronic device 3, and a user 4 can remotely set the power supply time by rotating the time adjustment wheel 21 on the remote controller body 2. The time adjustment wheel 21 on the remote controller body 2 includes two sets of time setting specification (the first set: OFF, ON, SENSOR, 1H, 2H, 3H, 4H; the second set: OFF, ON, 5H, 6H, 7H, 8H, 9H). Upon pressing down the first switch control button 22 by the user 4, the first set of time setting specification can be enabled; contrarily, when the user presses down the second switch control button 23, the second set of time setting specification can be enabled, thereby allowing the user 4 to switch the setting of the power supply time for the outdoor electronic device 3.

Refer next to FIGS. 5A and 5B, wherein, in comparison with the aforementioned contents, the difference essentially lies in that the display 12 and the time adjustment button 13 of the socket body 1 are conjunctively replaced with a rotary switch 19 installed on the cover 15; furthermore the time adjustment button input module 178 and the display module 179 of the socket power control circuit are substituted by a rotary switch input module 191.
