[0020] In order to make the above objects, features, and advantages of this utility model more understandable, the following will describe the specific embodiments of this utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand this utility model. However, this utility model can be implemented in many other ways different from this description, and those skilled in the art can make similar improvements without departing from the connotation of this utility model. Therefore, this utility model is not limited by the specific embodiments disclosed below.

[0021] Such as Figure 1As shown, the utility model discloses an intelligent socket with dual sensing, which includes: The socket 1 is provided with an LED night light 13, a human body infrared sensor 2, an ambient light sensor 3, a first LED light 11 and a button 10;

[0022] Combined with Figure 2 As shown, an EMC filter rectifier circuit is arranged in the socket 1. The input end of the EMC filter rectifier circuit is electrically connected to the mains power supply, and the output end of the EMC filter rectifier circuit is electrically connected to a buck circuit. The buck circuit is used for DC low-voltage power supply. The buck circuit includes: a Buck buck circuit and an LDO buck circuit. The EMC filter rectifier circuit, the Buck buck circuit and the LDO buck circuit are conventional circuits;

[0023] A main control is arranged in the socket 1. The main control can be an MCU. The main control is electrically connected to a communication module. The communication module is electrically connected to an LED control circuit, an ambient light sensor control circuit and an infrared induction control circuit. The LED control circuit is electrically connected to the LED night light 13. The infrared induction control circuit is electrically connected to the human body infrared sensor 2. The ambient light sensor control circuit is electrically connected to the ambient light sensor 3.

[0024] Combined with Figure 7 As shown, the communication module can be a WiFi communication module, which is used to realize remote control and monitoring of users, and realize data interaction between various circuits and modules. For example: Users can realize remote control or monitoring of the socket through a mobile phone app.

[0025] Specifically, the LED control circuit is as Figure 3 shown. It controls the on and off of the MOS tube Q1 according to the control signal to realize the opening and closing of the LED night light.

[0026] Specifically, the infrared induction control circuit is as Figure 4 shown. It realizes the detection of the presence of users through the human body infrared sensor PIR1.

[0027] Specifically, the ambient light sensor control circuit is as Figure 5 shown. It realizes the detection of the ambient brightness of users through the ambient light sensor U6.

[0028] Judge whether the current ambient brightness meets the condition for turning on the LED night light through the ambient light sensor, and judge whether the user needs to turn on the LED night light through the human body infrared sensor, so as to realize the turning on of the LED night light only when the ambient light is relatively dim, and avoid the user accidentally turning on the LED night light.

[0029] Specifically, combined with Figure 2As shown, the communication module is electrically connected to the relay control circuit, which is used to control the opening and closing of the jacks of the socket, and the relay control circuit is a conventional circuit.

[0030] Furthermore, a key control circuit electrically connected to the main control can be provided. The key control circuit is electrically connected to the button. The button, in cooperation with the relay control circuit, enables the user to manually control the opening and closing of the socket, and the button can also be used to manually control the opening and closing of the LED night light. Among them, Figure 1 The first LED lamp 11 shown can be an indicator light. The first LED lamp 11 can be electrically connected to the relay control circuit and indicate the current opening and closing state of the socket, or be used for other indication purposes.

[0031] Specifically, as Figure 1 、 Figure 2 shown, the communication module is electrically connected to the over-temperature protection circuit. The over-temperature protection circuit detects the temperature of the elastic piece (the temperature of the copper foil elastic piece) of the jack 12 in the socket 1 through a thermistor. The over-temperature protection circuit is as Figure 6 shown. It realizes over-temperature detection through the thermistor NTC1. When the temperature of the thermistor reaches 80 - 90 degrees Celsius, the MOS tube Q2 will conduct. At this time, the over-temperature protection circuit outputs a low level to the main control, and the main control will turn off the AC output through the relay control circuit to achieve the protection function.

[0032] In summary, through dual sensing of human body infrared sensing and ambient light sensing, it identifies the presence of the user and the current ambient brightness (distinguishing day and night), realizes sensing the user's actions at night and turning on the night light, thereby facilitating the user to use the socket; by setting up the relay control circuit and the over-temperature protection circuit, it realizes temperature detection of the socket and automatically disconnects from the mains when the temperature is too high, improving safety; the above-mentioned communication module can be a wireless communication module, enabling the socket to communicate with the user's handheld terminal, thereby facilitating the user to perform remote control and monitoring.

[0033] The above-described embodiments merely represent one or more implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
