Technical Field

[0002] As a core component of smart home systems, smart sockets not only need to provide basic power supply but also support device networking and remote control. Current technologies mostly employ a single communication method, which is insufficient to meet the needs of multi-device collaboration and complex scenarios.

[0003] Chinese patent application CN215870063U discloses a wireless smart socket with metering function, which uses a Zigbee wireless module to achieve wireless communication, mainly for wireless control and uploading of power metering data. However, although the Zigbee wireless module has networking capabilities, it may suffer from limited communication distance and weak penetration in practical applications. For example, in long-distance control, the smart socket needs to relay data through a Zigbee master device, relying on Zigbee networking and unable to directly connect to the Internet, thus limiting real-time performance. Furthermore, in short-distance control, the Zigbee wireless module's signal penetration is relatively weak; signal attenuation is significant when passing through walls, obstacles, or metal structures, potentially leading to unstable or interrupted communication between devices in complex environments. In addition, Zigbee wireless modules are expensive, resulting in high operating costs.

In specific implementation, the Bluetooth MESH module 3 adopts a low-power Bluetooth module with the model number EMB1016. It internally integrates an MX1510 Bluetooth microcontroller, which can use rich peripheral interfaces to achieve data acquisition and control, and communicate with other Bluetooth devices through the built-in Bluetooth subsystem. It can not only directly interact with a mobile phone but also access the IoT cloud service platform through the Bluetooth Mesh network with data.

[0046] As described above, the Bluetooth Mesh technology of the Bluetooth Mesh module 3 provides stronger communication capabilities and better signal penetration, making communication between devices more stable and reliable, and maintaining strong penetration even in short-range control. Simultaneously, since the Bluetooth Mesh network can directly access the IoT cloud service platform, remote monitoring and management of devices can be achieved. Even when the IoT module 2 is not working, device data can still be directly uploaded to the cloud server for remote monitoring and management. Furthermore, the configuration of the first transmitting end T11 and the first receiving end T12 of the Bluetooth Mesh module 3 facilitates subsequent signal transmission with the IoT module 2. The configuration of the first reset end T13 allows the IoT module 2 to reset the Mesh chip by controlling the first reset end T13 when the socket malfunctions, thereby restoring normal device operation and reducing service interruptions caused by device failure. In addition, the stamp-hole packaging and small size of the EMB1016 module facilitate integration into various embedded devices, making it more suitable for the smart socket in this case and simplifying the product design and manufacturing process.

[0047] like Figure 4 As shown, the IoT module 2 includes: an IoT chip U2 and its peripheral circuits. The IoT chip U2 is provided with a second receiving terminal T21 electrically connected to the first transmitting terminal T11, a second transmitting terminal T22 electrically connected to the first receiving terminal T12, and a reset control terminal T23 electrically connected to the first reset terminal T13.

[0048] As described above, the second receiving end T21 of the IoT module 2 in this case is electrically connected to the first transmitting end T11, forming a data receiving channel. This enables the IoT module to receive data from other devices or modules, achieving bidirectional data transmission and providing a foundation for communication between IoT devices. The second transmitting end T22 is electrically connected to the first receiving end T12, forming a data sending channel. This allows the IoT module to send data to other devices or modules, achieving bidirectional data transmission and sharing. Dedicated receiving and transmitting ends improve the accuracy and efficiency of the IoT module's transmission and reception, enhancing communication stability. The reset control end T23 allows the IoT module to be restarted in case of socket malfunction or failure, ensuring stable device operation and data continuity.

[0049] like Figure 4As shown, in specific implementation, IoT module 2 adopts an IoT communication module supporting both Wi-Fi and Bluetooth dual-mode. Preferably, the EMC3180 communication module is used for IoT data communication. Through rich peripheral interfaces, it achieves data acquisition and device control. It can communicate directly with mobile devices via Bluetooth Low Energy or connect to an IoT cloud service platform via Wi-Fi network to achieve the Internet of Things. The module incorporates a highly integrated Wi-Fi / BLE Combo microcontroller, RTL8720CM, providing the necessary computing power and stable Wi-Fi / BLE connectivity for IoT data terminals. The module has 4MB of built-in PSRAM. The RTL8720CM is the aforementioned IoT chip, integrating Wi-Fi, Bluetooth Low Energy (BLE), and a high-performance microcontroller unit (MCU), designed specifically for IoT applications, providing functions such as network communication, data processing, and device control.

[0050] As described above, the IoT module 2 enables the socket in this design to connect directly to the internet for remote control, eliminating the need for data relay through the main control device and thus improving the real-time performance and stability of communication. Furthermore, the IoT module 2 utilizes an EMC3180 communication module, enabling it to support dual-mode communication via Wi-Fi and Bluetooth.

[0051] Specifically, in a Bluetooth MESH network, data can be transmitted through multiple paths, thus avoiding the risk of single points of failure. Even if a node fails, data can still reach the target node through other paths, ensuring data integrity and reliability. IoT module 2, as a node in the network, can send, receive, and forward data with other nodes, achieving seamless data communication between devices. When IoT module 2 connects to Bluetooth MESH module 3 via Bluetooth, they together form part of the network, ensuring the stability and reliability of the entire network.

[0052] like Figure 4 As shown, in a specific implementation, the peripheral circuit of the IoT chip U2 includes: a network distribution button circuit 21 and a reset circuit 22; the IoT chip U2 also includes a network distribution terminal T24 electrically connected to the network distribution button circuit 21 and a second reset terminal T25 electrically connected to the reset circuit 22.

[0053] The power distribution button circuit 21 includes: a power distribution button S1, a first capacitor C10, and a first resistor R6. One end of the first resistor R6 is electrically connected to the positive terminal of the DC power output of the DC power supply of the power management module 1, and the other end is connected to one end of the power distribution button S1. One end of the first capacitor C10 is connected to the other end of the first resistor R6, and the other end is grounded. The other end of the power distribution button S1 is grounded. The connection point between one end of the power distribution button S1, one end of the first capacitor C10, and the other end of the first resistor R6 serves as a power distribution status monitoring terminal and is electrically connected to the power distribution terminal T24.

[0054] The reset circuit 22 includes a second resistor R27 and a second capacitor C35. One end of the second resistor R27 is electrically connected to the positive terminal of the DC power output of the DC power supply of the power management module 1, and the other end is connected to one end of the second capacitor C35. The other end of the second capacitor C35 is grounded. The connection point between one end of the second resistor R27 and one end of the second capacitor C35 is electrically connected to the second reset terminal T25.

[0055] As described above, the distribution button circuit 21 in this case can trigger the IoT chip U2 to enter the distribution mode through the simple operation of the distribution button S1, realizing one-click distribution and improving the convenience and user experience of distribution. The combination of the first capacitor C10 and the first resistor R6 in the distribution button circuit 21, as well as the electrical connection between the distribution status monitoring terminal and the distribution terminal T24, enables the IoT chip U2 to monitor the status of the distribution button in real time, which helps to ensure the accuracy and stability of the distribution process. The reset circuit 22 in this case provides a reliable reset signal for the IoT chip U2 through the combination of the second resistor R27 and the second capacitor C35.

[0056] like Figure 4 and Figure 5As shown, in a specific implementation, the indicator module 4 connected to the IoT chip U2 includes: a first LED D1 indicating the power supply status, a second LED D2 indicating the operating status of the IoT module 2, and a third LED D3 indicating the operating status of the Bluetooth MESH module 3. The positive terminal of the DC power output of the power management module 1 is connected to the positive terminal of the first LED D1 through a first resistor R8, to the positive terminal of the second LED D2 through a second resistor R9, and to the positive terminal of the third LED D3 through a third resistor R10. The negative terminal of the first LED D1 is electrically connected to the first control terminal T41 of the IoT chip U2, the negative terminal of the second LED D2 is electrically connected to the second control terminal T42 of the IoT chip U2, and the negative terminal of the third LED D3 is grounded. Thus, by observing the illumination status of the first LED D1, the second LED D2, and the third LED D3, the user can intuitively monitor the DC power output status of the power management module 1, the operating status of the IoT module 2, and the operating status of the Bluetooth MESH module 3, providing a visual monitoring experience. Each LED is current-limited by corresponding resistors R8, R9, and R10, which ensures the normal operation of the LED while preventing excessive current from increasing energy consumption or damaging the components.

[0057] like Figure 6As shown, in a specific implementation, the power management module 1 includes: a socket interface 11, a fuse F1, a variable resistor RV1, a third capacitor XC1, an AC-DC power converter CJ1, a first inductor L1, a voltage regulator chip U1, a fourth capacitor C3, and a polarized capacitor EC1; the socket interface 11 is connected to the neutral wire, the live wire, and the ground wire respectively; one end of the fuse F1 is electrically connected to the live wire, and the other end is electrically connected to the first pin of the AC-DC power converter CJ1; the variable resistor RV1 and the third capacitor XC1 are connected to the neutral wire. The AC-DC power converter CJ1 is connected in parallel with the live wire. Its second pin is connected to the neutral wire, its third pin is grounded, and its fourth pin, serving as the voltage output terminal, is electrically connected to one end of the first inductor L1. The other end of the first inductor L1 is connected to the input pin of the voltage regulator chip U1. A fourth capacitor C3 is connected between the other end of the first inductor L1 and ground. The GND pin of the voltage regulator chip U1 is grounded, and its output pin serves as the DC power output terminal of the power management module 1. The polarized capacitor EC1 is connected between the output pin of the voltage regulator chip U1 and ground. The AC-DC power converter CJ1 is a power converter that converts 220V AC to 5V DC, such as PM1132. The voltage regulator chip U1 can be a forward low-dropout regulator chip of model ams1117-3.3. The 5V DC voltage regulator chip U1 outputs a 3.3V DC voltage, which serves as the power output terminal of the power management module 1 for connection to other modules. When the mains power is interrupted, it can be automatically powered by a power bank to maintain the operation of the internal modules. Users can still remotely check the status of the socket and the status of the connected devices through a mobile APP.

[0058] Thus, the fuse F1 provides short-circuit and overload protection, ensuring circuit safety. The AC-DC power converter stably converts 220V AC to 5V DC, which is further adjusted to 3.3V by the voltage regulator chip, ensuring a stable and reliable output voltage. A variable resistor RV1 and a third capacitor XC1 are connected in parallel for filtering, reducing input noise. The first inductor L1 and the fourth capacitor C3 form an LC filter circuit to smooth the output voltage. The module design is compact and easy to integrate, employing a high-efficiency AC-DC converter and a low-dropout voltage regulator chip to achieve low power consumption, low heat generation, and improved overall performance and reliability.

[0059] like Figure 1 and Figure 7 As shown, in a specific implementation, the circuit board 104 further includes an interface module 5. The interface module 5 includes a first interface circuit 51 for connecting a portion of the communication or control terminal of the IoT module 2, and a second interface circuit 52 for connecting a portion of the communication or control terminal of the Bluetooth MESH module 3. Both the first interface circuit and the second interface circuit 52 are header interfaces, which provide extended functions for the IoT module and the Bluetooth MESH module, allowing users to add or remove modules as needed to adapt to future smart home protocol upgrades.

[0060] like Figure 8 As shown, in a specific implementation, the circuit board 104 further includes: a charging power supply module 6; the charging power supply module 6 includes a TYPE-C charging interface J1, a rectifier and filter circuit 61, and a step-down voltage regulator circuit 62 connected in sequence; the rectifier and filter circuit 61 includes: a Schottky diode T1 for rectification, a fourth capacitor C1, and a fifth capacitor C2, the Schottky diode T1, the fourth capacitor C1, and the fifth capacitor C2 are all connected between the power output terminal of the TYPE-C charging interface J1 and ground, and the three are connected in parallel; the step-down voltage regulator circuit 62 adopts a low-dropout linear regulator U3, the input terminal of the low-dropout linear regulator U3 is connected to the power output terminal of the TYPE-C charging interface J1, and the output terminal serves as the power output terminal of the charging power supply module 6; a sixth capacitor C3 and a seventh capacitor C4 are also connected between the output terminal of the low-dropout linear regulator U3 and ground.

[0061] As described above, the TYPE-C charging interface J1 is designed to support fast charging in this socket. The Schottky diode T1, the fourth capacitor C1, and the fifth capacitor C2 in the rectifier-filter circuit 61 are connected in parallel to effectively rectify and filter the power output from the TYPE-C interface, reducing AC components, improving DC power quality, and ensuring charging efficiency. The buck regulator circuit 62 uses a low-dropout linear regulator U3, which can stably reduce the higher voltage provided by the TYPE-C interface to a voltage level suitable for device operation. The sixth capacitor C3 and the seventh capacitor C4 connected between the output of the low-dropout linear regulator U3 and ground further enhance the filtering effect, reducing ripple and noise in the output voltage, improving the purity and stability of the power supply, and helping to protect the device from damage caused by power fluctuations. Thus, the addition of the charging power supply module 6 in this design allows the circuit board 104 to not only support traditional power supply but also charge via the TYPE-C interface, greatly improving user convenience and flexibility. In practice, a 5V power supply can be connected through the TYPE-C interface, and after rectification and filtering, the voltage is stepped down to 3.3V by U3 to power the Bluetooth MESH module and the IoT module.

[0062] like Figure 1 and Figure 9As shown, in a specific implementation, the socket panel 101 has a first indicator light hole 1011 for the user to view the Bluetooth MESH module 3, a second indicator light hole 1012 for the user to view the working status of the IoT module 2, and a third indicator light hole 1013 for the user to view whether the entire five-hole socket is powered on. The socket panel 101 is also covered by a panel cover 105, which has an opening 1053 for the third indicator light hole 1013 and covers the first indicator light hole 1011 and the second indicator light hole 1012. The bottom of the bottom shell 102 has a wiring port 1021 for connecting the neutral wire, live wire, and ground wire.

[0063] As described above, the socket panel 101 has pre-drilled holes for a first indicator light 1011, a second indicator light 1012, and a third indicator light 1013, allowing users to intuitively understand the working status of the socket and its built-in modules. The addition of the panel cover 105 not only protects the internal electronic components of the socket from external interference and damage, but also, through the opening 1053 of the third indicator light 1013, simultaneously covers the first indicator light 1011 and the second indicator light 1012. Although the first and second indicator light 1011 and 1012 are covered by the panel cover 105, users can still clearly see the status of the third indicator light through the pre-drilled opening 1053, ensuring that users can obtain key information while avoiding visual interference caused by too many indicator lights. The wiring port 1021 at the bottom of the base 102 provides a convenient channel for connecting the neutral, live, and ground wires, facilitating wiring operations for electricians.
