Description

Technical Field

[0001] This invention relates to a safety socket, specifically to an intelligent safety socket and a method for active power-off and automatic fire extinguishing control. Background Technology

[0002] As a common electrical connection device in homes, offices, commercial spaces, and industrial settings, sockets are primarily used to connect external power sources to electrical loads. With the increasing number of various electrical devices and the widespread use of charging equipment and high-power appliances, sockets operate under high load and high frequency conditions for extended periods. Issues such as aging wiring, poor contact between the plug and socket, loose internal conductive components, excessive load power, short circuits, arcing, overcurrent, overvoltage, and abnormally high localized temperatures can all cause abnormal heating inside the socket, potentially leading to electrical fires in severe cases.

[0003] The main functions of existing ordinary sockets are focused on power connection and power transmission. Although some products are equipped with fuses, overload protectors, or other power-off protection structures, their judgment parameters are usually quite simple, mainly relying on the magnitude of the current for protection. When a socket experiences poor contact at the plug-in point, localized overheating of conductive parts, a rapid increase in temperature over a short period of time, or a significant temperature difference between different locations, these abnormal states do not necessarily accompany obvious overcurrent phenomena. Therefore, traditional single overcurrent or overload protection methods are insufficient to detect such potential risks in a timely manner.

[0004] Meanwhile, while some existing smart sockets can perform power consumption statistics, remote switching, or network control, their safety protection functions and remote communication functions are usually relatively independent. When the network connection is interrupted, if the protection parameters or judgment logic rely on the cloud, the socket's continuous safety protection capability can be easily affected. In addition, the linkage capability between existing sockets and external safety devices such as smoke detectors, combustible gas detectors, temperature alarms, and water immersion sensors is still insufficient, making it difficult to actively cut off the power supply to the load in the event of risks such as fire, gas leaks, or water immersion in the external environment.

[0005] More importantly, the electrical safety protection used in existing sockets usually relies on cutting off the power supply as the final protective action. When a short circuit, arc, poor contact, or device failure has caused an open flame or reached a high temperature inside the socket, even if the power supply circuit is cut off in time, there may still be residual heat, localized combustion, and the risk of reignition inside the socket. Simply cutting off the power cannot guarantee that the fire will be extinguished immediately, and the flame may further ignite flammable materials around the socket casing.

[0006] Therefore, how to identify potential risks and proactively cut off power supply before a fire occurs in a socket by using multi-dimensional electrical and temperature parameters, and how to implement automatic fire extinguishing without manual operation when an open flame or abnormally high temperature has already appeared inside the socket, while also taking into account remote alarms, independent protection against network outages, and linkage with external safety devices, has become a technical problem that needs to be solved in the existing smart socket safety technology. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides an intelligent safety socket and an active power-off and automatic fire extinguishing control method, which can effectively overcome the shortcomings of the prior art.

[0008] This invention is achieved through the following technical solution: a smart safety socket, comprising: The socket housing serves to form the installation and accommodating space for the intelligent safety socket; A power supply plug assembly is disposed in the socket housing and connected to an external power source and an electrical load to form a power supply circuit for supplying power to the electrical load; A power detection module is installed in the power supply circuit to collect the electrical parameters of the electrical load; A temperature detection module is installed inside the socket housing to collect temperature parameters inside the socket housing; The control module is electrically connected to the power detection module and the temperature detection module respectively, and is used to receive the electrical parameters and the temperature parameters, and determine whether the smart safety socket is in an abnormal working state according to the preset protection threshold. A power-off execution module is installed in the power supply circuit and electrically connected to the control module, and is used to cut off the power supply to the electrical load according to the power-off control signal output by the control module; An automatic fire extinguishing layer is disposed on the inner surface of the socket housing. The automatic fire extinguishing layer includes a perfluorohexanone microcapsule coating for releasing perfluorohexanone when exposed to an open flame and / or when the microcapsule rupture trigger temperature is reached. Specifically, when the control module determines that the smart safety socket is in an abnormal working state based on the electrical parameters and / or the temperature parameters, it controls the power-off execution module to cut off the power supply to the electrical load; when an open flame or abnormally high temperature is generated inside the socket housing, the perfluorohexanone microcapsule coating is heated and ruptures, releasing perfluorohexanone to extinguish or suppress the fire source inside the socket housing.

[0009] As a preferred technical solution, the electrical parameters include one or more of voltage, current, power, power factor, and energy consumption; the temperature parameters include one or more of the real-time temperature inside the socket housing, the rate of temperature change over a preset time, and the temperature difference between different detection locations.

[0010] As a preferred technical solution, the temperature detection module includes one or more temperature sensors, which are disposed at one or more locations near conductive components, near power supply plug-in components, near power-off execution modules, near circuit boards, and on the inner wall of the socket housing; the control module obtains the temperature difference between different detection locations based on the temperature parameters collected by different temperature sensors, and obtains the temperature change rate within a preset time based on the continuously collected temperature parameters.

[0011] As a preferred technical solution, the abnormal operating state includes one or more of the following: overcurrent state, overload state, overvoltage state, overtemperature state, local abnormal heating state, rapid temperature rise abnormal state, and overcharge state; the control module is used to compare the collected current, power, voltage, temperature, temperature difference, temperature change rate, and power consumption with the corresponding preset protection thresholds, and control the power-off execution module to cut off the power supply circuit when at least one of them meets the judgment condition of the corresponding abnormal operating state.

[0012] As a preferred technical solution, the system further includes a communication module and a local storage module, which are electrically connected to the control module. The communication module is used for data communication with the cloud management platform and / or the mobile terminal, and the local storage module is used to store preset protection thresholds issued by the cloud management platform and / or the mobile terminal. When the communication module is in a communication interruption state, the control module continues to perform abnormal working state judgment and active power-off protection according to the preset protection thresholds stored in the local storage module.

[0013] As a preferred technical solution, the perfluorohexanone microcapsule coating covers the inner wall surface of the socket housing and is disposed in at least one or more areas around the power supply plug assembly, the conductive component, the power-off execution module, and the circuit board; the thickness of the perfluorohexanone microcapsule coating is 0.2 mm to 3 mm.

[0014] As a preferred technical solution, the control module is further configured to determine whether the electrical load has entered a low-power state based on the power change data collected by the power detection module. When the power of the electrical load is lower than a preset low-power threshold and continues for a preset time, the control module controls the power-off execution module to cut off the power supply to the electrical load. Alternatively, the control module is configured to receive an alarm signal sent by an external linkage sensor and control the power-off execution module to cut off the power supply to the electrical load based on the alarm signal. The external linkage sensor includes one or more of a smart smoke detector, a combustible gas alarm, a temperature alarm, and a water immersion sensor.

[0015] The present invention provides a method for active power-off and automatic fire extinguishing control of an intelligent safety socket, comprising: Collect electrical parameters of the electrical load; Collect temperature parameters inside the smart safety socket; The electrical parameters and temperature parameters are compared with preset protection thresholds, and the comparison results are used to determine whether the smart safety socket is in an abnormal working state. When the smart safety socket is in an abnormal working state, it outputs a power-off control signal to the power-off execution module set in the power supply circuit, and cuts off the power supply to the electrical load through the power-off execution module; When an open flame and / or abnormally high temperature are generated inside the smart safety socket, the perfluorohexanone microcapsule coating on the inner surface of the socket housing will rupture due to heat and release perfluorohexanone, thereby extinguishing or suppressing the fire source inside the smart safety socket.

[0016] As a preferred technical solution, the judgment of abnormal working state includes: when the collected current is greater than the current threshold, it is judged as an overcurrent state; when the collected power is greater than the power threshold, it is judged as an overload state; when the collected voltage is greater than the voltage threshold, it is judged as an overvoltage state; when the collected temperature is greater than the temperature threshold, it is judged as an overtemperature state; when the temperature difference between different detection locations is greater than the temperature difference threshold, it is judged as a local abnormal heating state; when the temperature change rate within a preset time is greater than the temperature change rate threshold, it is judged as a rapid heating abnormal state; when the cumulative power consumption is greater than the power consumption threshold, it is judged as an overcharge state; when at least one of the above abnormal working state judgment conditions is met, the power-off execution module is controlled to cut off the power supply.

[0017] As a preferred technical solution, the method further includes: receiving protection threshold configuration parameters issued by a cloud management platform and / or a mobile terminal, and storing the protection threshold configuration parameters in a local storage module; when communication is normal, performing abnormal working state judgment according to the received protection threshold configuration parameters; when communication is interrupted, continuing to perform abnormal working state judgment and active power-off protection according to the protection threshold configuration parameters stored in the local storage module, and uploading alarm records and / or power consumption records generated during the communication interruption to the cloud management platform after communication is restored.

[0018] The beneficial effects of this invention are: 1. This invention collects electrical parameters of the electrical load and temperature parameters inside the socket through a power detection module and a temperature detection module, respectively. This enables the control module to not only judge overcurrent, overload and overvoltage states based on parameters such as current, power and voltage, but also to identify local abnormal heating and rapid heating states based on real-time temperature, temperature difference between different detection locations and temperature change rate. This expands the monitoring dimensions of abnormal socket states and improves the ability to identify electrical fire precursors such as poor contact and local heating.

[0019] 2. The present invention sets up a power-off execution module connected to the control module in the power supply circuit. When any electrical parameter or temperature parameter meets the judgment conditions of abnormal working state, the control module can output a power-off control signal in a timely manner and cut off the power supply to the electrical load, so that the dangerous state can be suppressed before it further develops into a short circuit, electric arc or open flame, forming the first active safety defense against electrical fire risk.

[0020] 3. The present invention provides an automatic fire extinguishing layer with a perfluorohexanone microcapsule coating inside the socket housing. When an open flame or abnormally high temperature occurs inside the socket, the microcapsules rupture due to heat and release perfluorohexanone, allowing the fire extinguishing medium to act directly on the fire source area inside the socket. By absorbing heat and cooling down, inhibiting combustion, and covering the fire source area, the fire is extinguished or reignition is inhibited. Thus, after the power is actively cut off, the fire source that has already formed is further treated, forming a second line of defense for safety.

[0021] 4. This invention combines electrical anomaly monitoring with active power-off protection and an automatic fire suppression layer. Active power-off is used to reduce the possibility of electrical faults continuing to develop, while the automatic fire suppression layer is used to deal with residual high temperature, local combustion and reignition risks that still exist after power failure. The two form a dual protection system that combines front-end prevention and back-end fire suppression. Compared with sockets that only have overcurrent protection or simple power-off functions, it can further reduce the risk of electrical fires caused by internal socket faults.

[0022] 5. This invention enables data communication between the smart safety socket, the cloud management platform, and the mobile terminal through a communication module, and saves protection thresholds through a local storage module, allowing protection parameters to be configured externally. In the event of a communication interruption, the control module can still independently complete anomaly judgment and active power cut-off based on the locally stored protection thresholds, avoiding excessive reliance on network connection for the socket's safety protection function and improving the continuity and reliability of system operation.

[0023] 6. This invention can also identify low-power states based on changes in the power of the electrical load, and actively cut off the power supply after the low-power state has lasted for a preset time, thereby reducing energy consumption and safety hazards caused by long-term low-power standby of devices such as chargers; at the same time, it can also receive alarm signals from external linkage sensors such as smart smoke detectors, combustible gas detectors, temperature detectors and water immersion sensors, and actively perform power-off protection when there is a risk in the external environment, further expanding the comprehensive safety protection capabilities of the smart safety socket.

Detailed Implementation

[0026] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0027] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0028] like Figures 1-4As shown, the smart safety socket in this embodiment includes a socket housing 1, a power supply connection assembly 2, a power detection module 3, a temperature detection module 4, a control module 5, a power-off execution module 6, a communication module 7, a local storage module 8, and an automatic fire extinguishing layer 9. The socket housing 1 constitutes the main mounting structure of the smart safety socket, and its interior forms a space for accommodating the power supply connection assembly 2, the power detection module 3, the temperature detection module 4, the control module 5, the power-off execution module 6, the communication module 7, and the local storage module 8. The socket housing 1 can be made of engineering plastics, flame-retardant composite materials, or other materials that meet electrical insulation and heat resistance requirements to isolate and protect the internal electrical components during normal use.

[0029] The power supply plug assembly 2 is disposed on the socket housing 1. One side of the power supply plug assembly 2 is used to establish an electrical connection with an external power source, and the other side is used to establish an electrical connection with the electrical load plugged into the smart safety socket, thereby forming a power supply circuit for the external power source to deliver electrical energy to the electrical load. Depending on the actual use of the socket, the power supply plug assembly 2 may include components such as a power input terminal, a socket assembly, conductive copper parts, a grounding connector, and internal wires. It can be used in two-hole sockets, three-hole sockets, power strips with multiple plug positions, or other electrical equipment with socket functions.

[0030] The power detection module 3 is installed in the power supply circuit formed by the power supply plug-in assembly 2, enabling the electrical energy parameters flowing to the electrical load to be collected in real time or periodically. The power detection module 3 may include a voltage detection unit, a current detection unit, and an energy metering unit. Through corresponding sampling circuits, it obtains one or more electrical parameters among voltage, current, power, power factor, and energy consumption during the operation of the electrical load. In practical applications, current detection can be achieved using a sampling resistor, current transformer, or Hall effect current sensor; voltage detection can be achieved through a resistor voltage divider sampling circuit; and power and energy consumption can be calculated by the corresponding energy metering chip based on the collected voltage and current data, thereby enabling the control module 5 to obtain electrical parameters reflecting the current operating status of the electrical load.

[0031] The temperature detection module 4 is located inside the socket housing 1 and is used to monitor the thermal state inside the socket housing 1. The temperature detection module 4 may include one temperature sensor or multiple temperature sensors respectively located at different detection positions. When multiple temperature sensors are used, each temperature sensor may be located near the power supply connector 2, near the internal conductive parts, near the power-off execution module 6, near the circuit board, or on the inner wall of the socket housing 1, thereby obtaining temperature data for different areas. The control module 5 can obtain the real-time temperature inside the socket based on the temperature at any of the detection positions, calculate the temperature difference between different detection positions based on the temperature data, and calculate the rate of temperature change based on the temperature data at the same detection position over a continuous time period.

[0032] Through the above detection method, when there is poor contact between the power supply plug assembly 2 and the plug, or when the internal conductive parts become loose or oxidized, the abnormal heating generated in the local area can still be detected by the temperature detection module 4 even if the current in the power supply circuit has not reached a significant overcurrent level. The control module 5 further determines whether there is local abnormal heating by measuring the temperature difference between different detection locations or the rapid temperature rise within a preset time. This allows the smart safety socket to no longer rely solely on the current magnitude to determine potential electrical faults, enabling more comprehensive monitoring of internal thermal anomalies within the socket.

[0033] The control module 5 is electrically connected to the power detection module 3, the temperature detection module 4, and the power-off execution module 6. The control module 5 receives electrical parameters from the power detection module 3 and temperature parameters from the temperature detection module 4, and determines the current operating status of the smart safety socket based on pre-set protection thresholds. The control module 5 can be implemented using a microcontroller, MCU, embedded processor, or other processor capable of data acquisition, comparison, judgment, and control output, and it runs a corresponding electrical safety control program internally.

[0034] In this embodiment, the preset protection thresholds may include at least a current threshold, a voltage threshold, a power threshold, a temperature threshold, a temperature difference threshold, a temperature change rate threshold, and a power consumption threshold. Each preset protection threshold can be configured according to the rated power of the smart safety socket, the usage scenario, and the type of electrical load connected. The control module 5 compares the data obtained by the power detection module 3 and the temperature detection module 4 with the corresponding preset protection thresholds, thereby achieving a comprehensive judgment on multiple abnormal operating states.

[0035] Specifically, when the real-time current collected by the power detection module 3 is greater than the set current threshold, the control module 5 determines that the power supply circuit is in an overcurrent state; when the detected load power is greater than the power threshold, it is determined to be an overload state; when the detected voltage is greater than the voltage threshold, it is determined to be an overvoltage state; when the temperature detection module 4 detects that the temperature at any detection location is higher than the temperature threshold, it is determined to be an overtemperature state; when the temperature difference between different detection locations is greater than the temperature difference threshold, it is determined to be a local abnormal heating state; when the rate of temperature rise within a preset time range is greater than the temperature change rate threshold, it is determined to be a rapid temperature rise abnormal state; when the cumulative power consumption exceeds the set power consumption threshold, it is determined to be an over-power state.

[0036] The aforementioned abnormal operating states can be judged independently or in combination. When any one of the abnormal operating states reaches the preset trigger condition, the control module 5 can output a power-off control signal without waiting for other parameters to reach the abnormal state simultaneously. For some demanding application scenarios, the control module 5 can also make a judgment based on multiple detection parameters. For example, when the load current approaches the current threshold and the temperature near the power supply plug component 2 is detected to be rising continuously, the power-off protection can be executed in advance to further improve the response speed of electrical safety protection.

[0037] The power-off execution module 6 is located in the power supply circuit formed by the power supply plug-in assembly 2 and is electrically connected to the control module 5. Under normal operating conditions, the power-off execution module 6 keeps the power supply circuit open, allowing external power to continuously supply power to the electrical load via the power supply plug-in assembly 2. When the control module 5 determines that the smart safety socket is in an abnormal operating state, the control module 5 outputs a power-off control signal to the power-off execution module 6. The power-off execution module 6 changes its own conduction state according to the power-off control signal, disconnecting the power supply circuit and thus stopping the continued supply of power to the electrical load.

[0038] The power-off actuator 6 can use relays, magnetic latching relays, solid-state relays, contactors, thyristors, or other electrical actuators capable of controlling the on / off state of a circuit. The power-off actuator 6 can be installed on the live wire of the power supply circuit, allowing the live wire to be directly disconnected in case of an abnormality. Alternatively, it can control the live wire and neutral wire separately according to safety level requirements, enabling more thorough electrical isolation when the smart safety socket malfunctions.

[0039] To further address the issue that simply cutting off the power is insufficient to completely eliminate the fire risk once an open flame has appeared in the socket, this embodiment incorporates an automatic fire extinguishing layer 9 on the inner surface of the socket housing 1. The automatic fire extinguishing layer 9 includes a perfluorohexanone microcapsule coating. Perfluorohexanone is encapsulated within microcapsules and formed inside the socket housing 1 through coating or adhesion. When the socket is within its normal operating temperature range, the microcapsules remain stable and do not affect the normal operation of the electrical components inside the socket.

[0040] The automatic fire extinguishing layer 9 can cover most of the inner wall surface of the socket housing 1, or it can be strategically placed according to the probability of arcing, short circuits, or abnormal heating at different locations inside the socket. For example, a relatively concentrated perfluorohexanone microcapsule coating can be applied around the power supply connector 2, the conductive parts corresponding to the sockets, the power-off execution module 6, and the internal circuit board, bringing the automatic fire extinguishing medium closer to potential ignition sources. The thickness of the perfluorohexanone microcapsule coating can be set from 0.2mm to 3mm, meeting the requirements for fire extinguishing medium storage while avoiding the coating occupying excessive internal installation space.

[0041] When an open flame or abnormally high temperature is generated inside the socket housing 1 due to a short circuit, arc, poor contact, device failure, or abnormal overload, even if the control module 5 has cut off the power supply through the power-off execution module 6, the local high temperature and the already ignited combustibles may continue to burn. At this time, the perfluorohexanone microcapsule coating located near the corresponding high-temperature area is directly affected by the open flame or the temperature reaches the microcapsule rupture trigger temperature, causing the microcapsule wall material to rupture and releasing the perfluorohexanone stored inside into the socket housing 1.

[0042] Upon release, perfluorohexanone rapidly vaporizes under high temperatures. This vaporization process absorbs heat from the fire source and surrounding area, lowering the local temperature. Simultaneously, perfluorohexanone acts on the flame area, inhibiting the combustion reaction and forming a fire-extinguishing medium covering the vicinity of the fire source, thus extinguishing or suppressing existing flames. Therefore, control module 5, power-off execution module 6, and automatic fire extinguishing layer 9 address electrical anomalies before a fire occurs and the combustion state after a fire has formed, respectively, enabling the smart safety socket to provide a two-tiered safety protection system combining active power-off and automatic fire extinguishing.

[0043] The communication module 7 is electrically connected to the control module 5, enabling data interaction between the smart safety socket, the cloud management platform 10, and the mobile terminal 11. The communication module 7 can use WiFi, 4G, 5G, NB-IoT, LoRa, Bluetooth, or other wired or wireless communication methods. In actual use, the control module 5 can upload information such as the smart safety socket's current voltage, current, power, temperature, energy consumption, device status, and alarm status to the cloud management platform 10 via the communication module 7. Users can view this data through the mobile terminal 11.

[0044] The cloud management platform 10 or mobile terminal 11 can also send protection threshold configuration parameters to the smart safety socket. For example, for electrical devices with different rated power, corresponding current thresholds and power thresholds can be set respectively. For usage environments that are more sensitive to temperature, the temperature threshold or temperature change rate threshold can be reduced, so that the smart safety socket can form corresponding safety protection strategies according to different usage scenarios.

[0045] The local storage module 8 is electrically connected to the control module 5 and is used to store protection threshold configuration parameters issued by the cloud management platform 10 and / or the mobile terminal 11. The local storage module 8 can also be used to save device number, communication parameters, alarm records, historical power consumption data, and device operating status data. When the network connection between the communication module 7 and the cloud management platform 10 is normal, the control module 5 can receive the latest protection threshold and write it to the local storage module 8; when the network is interrupted, the control module 5 does not need to rely on the cloud for real-time judgment, but directly reads the protection threshold already saved in the local storage module 8 to continue judging abnormal operating states.

[0046] Therefore, even if the communication module 7 cannot establish a communication connection with the cloud management platform 10 or the mobile terminal 11 temporarily, the power detection module 3, temperature detection module 4, control module 5, and power failure execution module 6 can still form a complete detection, judgment, and power failure protection closed loop locally on the smart safety socket, and will not lose its safety protection function due to network interruption. When the network is restored, the control module 5 can re-upload the abnormal events, alarm records, and power consumption records recorded during the network outage to the cloud management platform 10 through the communication module 7, thereby ensuring the continuity of equipment operation data.

[0047] The control module 5 can also identify whether the electrical load has entered a low-power state based on the power change data collected by the power detection module 3. For example, when a mobile phone charger, tablet charger, or other charging device is connected to the power supply plug component 2, the load power during the normal charging phase is usually kept in a relatively high range, while as the device being charged gradually becomes fully charged, its load power will gradually decrease. When the control module 5 detects that the current load power is lower than the preset low-power threshold, and this state is maintained continuously for a preset time, it can determine that the electrical load has entered a low-power state.

[0048] After determining that the electrical load has entered a low-power state, the control module 5 sends a power-off control signal to the power-off execution module 6, causing the power-off execution module 6 to disconnect the power supply circuit, thereby stopping the continued supply of power to loads that have completed charging or have been in a low-power standby state for a long time. This method can not only reduce unnecessary standby power consumption, but also reduce the heat generation, component aging, and potential electrical safety risks caused by the continuous power supply of chargers and other electrical equipment for a long time.

[0049] like Figure 4 As shown, the smart safety socket in this embodiment can also form a smart linkage relationship with the external linkage sensor 12. The external linkage sensor 12 may include one or more of the following: smart smoke detector, combustible gas alarm, temperature alarm, and water immersion sensor. The external linkage sensor 12 can send alarm signals to the smart safety socket through the cloud management platform 10, or it can directly establish a communication connection with the communication module 7 through a local area network, Bluetooth, LoRa, NB-IoT, or other communication methods.

[0050] When the smart smoke detector detects that the smoke concentration in the environment reaches the alarm condition, or the combustible gas alarm detects a gas leak, or the temperature alarm detects an abnormal external ambient temperature, or the water immersion sensor detects water immersion in the area where the socket is located, the corresponding external linkage sensor 12 generates an alarm signal. After receiving the alarm signal through the communication module 7, the control module 5 can directly output a power-off control signal to the power-off execution module 6, cutting off the power supply in advance before the socket itself detects any obvious electrical abnormalities, thereby reducing the possibility of external environmental risks further causing electric shock, short circuits, or electrical fires.

[0051] The smart safety socket can also be equipped with an alarm indicator module 13, which is connected to the control module 5. When the control module 5 determines that there is an overcurrent, overload, overvoltage, overtemperature, local abnormal heating, rapid temperature rise abnormality, over-charge state, or receives an alarm signal from the external linkage sensor 12, in addition to controlling the power-off execution module 6 to execute the power-off, it can also output a local alarm prompt through the alarm indicator module 13. The alarm indicator module 13 can be an indicator light, a buzzer, or a display component, so that users can be promptly informed on-site that the smart safety socket is currently in an abnormal or protective state.

[0052] like Figure 3 As shown in the figure, in this embodiment, after the smart safety socket is powered on, the control module 5 first completes initialization and reads the protection threshold configuration parameters stored in the local storage module 8. Simultaneously, the power detection module 3 and temperature detection module 4 are activated to collect data. The communication module 7 attempts to establish a communication connection with the cloud management platform 10. Once the connection is successful, the control module 5 can receive the latest protection threshold configuration parameters from the cloud management platform 10 or the mobile terminal 11 through the communication module 7 and write the updated parameters into the local storage module 8.

[0053] During normal operation of the smart safety socket, the power detection module 3 continuously collects one or more electrical parameters from the electrical load, including voltage, current, power, power factor, and energy consumption. The temperature detection module 4 simultaneously collects the real-time temperature inside the socket housing 1 and obtains the corresponding temperature difference and temperature change rate based on multiple temperature detection locations. The control module 5 continuously compares the collected data with the corresponding preset protection thresholds, thereby cyclically determining whether the smart safety socket is in an abnormal operating state.

[0054] When none of the detection data meets the abnormal judgment conditions, the control module 5 keeps the power-off execution module 6 in a normal conducting state and continues to collect electrical and temperature parameters. When any detection parameter reaches the corresponding abnormal operating state judgment condition, the control module 5 immediately outputs a power-off control signal to the power-off execution module 6 to disconnect the power supply circuit. At the same time, it can upload alarm information to the cloud management platform 10 and / or mobile terminal 11 via the communication module 7. The alarm information may include information about the abnormal equipment, the type of abnormality, the time of occurrence, real-time voltage, real-time current, real-time power, temperature parameters, and the power-off execution status, so that users can be informed of the abnormal situation in a timely manner.

[0055] After the power-off action is executed, if no open flame or abnormally high temperature is generated inside the socket housing 1, the smart safety socket can maintain the power-off protection state and wait for manual reset or re-execution of the test according to the preset recovery conditions. When an open flame has been generated inside the socket housing 1 or its local temperature reaches the rupture trigger temperature of the perfluorohexanone microcapsules, the perfluorohexanone microcapsules in the automatic fire extinguishing layer 9 will rupture and release perfluorohexanone, which will act on the fire source area to extinguish or suppress the open flame and reduce the possibility of residual heat causing reignition.
