[0032] It should be noted that the first printed circuit board 5 and the second printed circuit board 6 are both PCBs (Printed Circuit Board, abbreviated as PCB) known in the art.

[0033] The length direction of the shell 4 is Figure 1 from the lower left to the upper right or from the upper right to the lower left. The width direction of the shell 4 is Figure 1 from the upper left to the lower right or from the lower right to the upper left.

[0034] In some embodiments, as Figure 2 shown, the first printed circuit board 5 includes an overload protection circuit 51, an AC / DC power supply circuit 52, and a relay circuit 53.

[0035] Specifically, the overload protection circuit 51 is used to avoid the risk of damage to the power strip caused by overload of the input power supply.

[0036] Specifically, as Figure 6 shown, the AC / DC power supply circuit 52 is used to convert 220V mains into 5V and 12V DC voltages, the 12V DC voltage is used to power the relay circuit 53, and the 5V DC voltage is used to power the second printed circuit board 6.

[0037] Specifically, the relay is of the model “Delixi CDZ9-62PL”.

[0038] In some embodiments, as Figure 3 shown, the second printed circuit board 6 includes a power management circuit 61, an ESP32 module circuit 62, and a battery pack 63.

[0039] The power management circuit 61 is used for battery charging and discharging, and power management of step-up and step-down output; the ESP32 module circuit 62 is used for wireless communication with the host computer device 8; and the battery pack 63 is used for storing electrical energy.

[0040] Specifically, the host computer device 8 is a smartphone.

[0041] Specifically, the battery pack uses the model “3500mAh 3.7V Yiwai 18650 flat head lithium battery”.

[0042] Specifically, as Figure 4 , 8As shown, the power management circuit 61 includes a DC / DC power module 611, a linear charging module 612, an analog-to-digital conversion module 613, and an intelligent protection module 614. When the smart wireless power strip is powered on, the DC / DC power module 611 of the power management circuit 61 converts the 5V input DC voltage to a 3.3V DC voltage to power the ESP32 module circuit; the linear charging module 612 can convert the 5V DC voltage to a 4.2V DC voltage to store energy for the battery pack 63; the analog-to-digital conversion module 613 and the intelligent protection module 614 monitor the input and output voltage and current parameters in real time, and respond to sudden accidents to ensure normal operation of the circuit.

[0043] Specifically, as shown in Figure 5 、 7 The ESP32 module circuit 62 includes a control module 621, a timing module 622, and a wireless communication module 623. The control module 621 is used to control the relay circuit 53 to control whether the five-hole socket 3 is powered on or not. The timing module 622 is used to realize the timing function. The wireless communication module 623 is used to realize wireless connection with the host computer device 8. The host computer device 8 can be a smart phone.

[0044] In some embodiments, when the smart wireless power strip is in a power-off state, the battery pack 63 can boost the battery voltage to 5V DC voltage through the DC / DC power module 611 of the power management circuit 61, and provide short-term power to the outside through the USB socket 7.

[0045] Thus, the USB socket 7 can still provide power to the outside when the smart wireless power strip is in a power-off state.

[0049] Specifically, the ESP32 module circuit 62 pushes the message content as the working state of the five-hole socket 3.

[0050] Specifically, the APP can set the working state instructions of the five-hole socket 3 as: immediately turn on, immediately turn off, timing turn on, and delay turn off.

[0051] It needs to be further explained that the master control chip of the ESP32 module circuit 62 is programmed with a code program for data communication with the smart phone, which is the prior art. When the instruction set by the APP is to immediately turn on or turn off the five-hole socket 3, the control module 621 of the ESP32 module circuit 62 will control the relay circuit 53 through the signal line to control the five-hole socket 3 to turn on or off; when the instruction set by the APP is to turn on or turn off the five-hole socket 3, the timing module 622 of the ESP32 module circuit 62 will count according to the timing information, and when the preset countdown is reached, the control module 621 of the ESP32 module circuit 62 will control the relay circuit 53 through the signal line to control the five-hole socket 3 to turn on or off.

[0052] Therefore, the intelligent wireless extension socket can be independently controlled by the smart phone APP to remotely and non-contactly control the timing on-off of each five-hole socket 3 in the power-on working state.

[0053] In some embodiments, the wireless extension socket is placed indoors and connected with the mains power supply through the triangular interface 1, and the supply voltage is 220V.

[0054] Specifically, the triangular interface 1 is IEC60320-C14.

[0055] Therefore, the wireless design with external wires eliminates the constraint of cable, and the user can flexibly move the extension socket and conveniently store it.

[0056] The beneficial effects of the utility model are:

[0057] 1. By modifying the existing extension socket structure, an energy storage circuit is added, and the internal battery pack is actively charged when the extension socket is powered on. In the power-off state, the battery pack can ultimately supply power to the outside through the USB socket. This design can ensure the normal operation of some key equipment, avoid data loss or equipment failure caused by power failure, and meet the short-term power supply demand.

[0058] 2. The extension socket is used with the APP of the host computer equipment to remotely and independently control whether each five-hole socket is powered on or off, and can be operated in timing mode to independently control the timing on of each five-hole socket and the delay off. Non-contact control can improve the operation convenience and simplify the daily power management, and timing control can prevent external heating equipment from working for a long time, reduce the power hazard and improve the safety.

[0059] 3. Compared with the existing intelligent extension socket, the utility model adopts a wireless design with a triangular interface to eliminate the constraint of cable, and the user can flexibly move the extension socket and conveniently store it.
