[0041] In this application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the relationship between related objects and indicates that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or a similar expression refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a alone, b alone, or c alone can mean: a alone, b alone, c alone, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b, and c, where a, b, and c can be single or multiple. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] The orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "upper", "lower", "left", "right", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of this application.

[0043] The terms "connected" and "coupled" should be understood in a broad sense. For example, the "connection" or "coupling" of a circuit structure can refer not only to a physical connection but also to an electrical connection or a signal connection. For example, it can be a direct connection, that is, a physical connection, or it can be indirectly connected through at least one intermediate element, as long as the circuit is connected. It can also be the communication inside two elements; the signal connection can be not only through a circuit for signal connection but also through a media medium for signal connection. For example, radio waves. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0044] Currently, there are surface-mounted fixed sockets and flush-mounted sockets that meet the standards of IEC60884-1, GB1002, and GB / T2099.1, converter sockets that meet the scope of GB / T2099.3, and extension cord sockets in the form of power strips that meet the scope of GB / T2099.7. Among the flush-mounted sockets, the flush-mounted sockets without a switch have no switch function and require manual plugging and unplugging of the power plug to control power on or off. For the flush-mounted sockets with a switch, it is necessary to manually press the switch button to control power on or off. Smart sockets need to be additionally equipped with a gateway network to control the smart sockets. And in the case of no network, the smart sockets can only be used as ordinary sockets.

[0045] Among them, the deficiencies of the converter socket and the extension cord socket are similar to those of the flush-mounted socket, so they will not be elaborated here.

[0046] Based on the above description, it can be seen that currently these sockets require manual operation or additional gateway network to control the power on or off of the socket, resulting in inconvenience to users and the problem of relatively high cost.

[0047] To solve the above problems, the present application provides a control circuit and a socket for a socket.

[0048] Referring to Figure 1 , Figure 1 , which is a schematic structural diagram of a control circuit for a socket provided by an embodiment of the present application. As shown in the figure, the control circuit 100 of the socket may include: an induction recognition circuit 110 and a driving circuit 120.

[0049] The first output end of the induction recognition circuit 110 is electrically connected to the input end of the driving circuit 120, the first output end of the driving circuit 120 is electrically connected to the load end of the socket, and the second output end of the driving circuit 120 is electrically connected to the live wire.

[0050] Among them, the induction recognition circuit 110 and the driving circuit 120 may be separately provided or integrated, and the embodiments of the present application do not make specific limitations on this.

[0051] The induction recognition circuit 110 can recognize an induction signal generated based on the user's body movement to obtain a driving signal CONT1. Moreover, the induction recognition circuit 110 can transmit the driving signal CONT1 to the driving circuit 120 so that the driving circuit 120 can obtain the driving signal CONT1.

[0052] Among them, the induction signal is generated based on the user's body movement. The body movement can be a hand movement or a leg movement, and the embodiments of the present application do not make specific limitations on this. For example, the hand movement is waving or a virtual finger pointing gesture.

[0053] In this way, the driving circuit 120 can control the conduction between the load end and the live wire according to the driving signal CONT1 to turn on the socket. Or, the driving circuit 120 can control the disconnection between the load end and the live wire according to the driving signal CONT1 to turn off the socket. In this way, there is no need to unplug the plug manually like a common socket to cut off the power, no need to touch and press the switch of the socket with a switch to cut off the power, and no need to add an additional gateway network like a smart socket to control the socket. Furthermore, it is possible to control the power on or off of the socket without manual operation or additional gateway network. Thus, it can provide convenience to users and reduce costs.

[0054] Exemplarily, for example, when the drive signal CONT1 is at a high level, the drive circuit 120 can control the conduction between the load terminal and the live wire. Also for example, when the drive signal CONT1 is at a low level, the drive circuit 120 can control the disconnection between the load terminal and the live wire.

[0055] For the control circuit of the socket provided in this application, the induction recognition circuit can recognize the induction signal generated based on the user's body movement, obtain the drive signal, and transmit the drive signal to the drive circuit, so that the drive circuit can obtain the drive signal. In this way, the drive circuit can control the conduction or disconnection between the load terminal and the live wire according to the drive signal, to energize or de-energize the socket. Furthermore, it is possible to control the energization or de-energization of the socket without manual operation or additional gateway network. Thus, it can provide convenience to users and reduce costs.

[0056] Based on the description of the above embodiments, exemplarily, a possible implementation manner of the control circuit 100 of the socket. As Figure 1 shown, the control circuit 100 of the socket may further include: an indication circuit 130.

[0057] The input end of the indication circuit 130 is electrically connected to the second output end of the induction recognition circuit 110, and the output end of the indication circuit 130 is used to output an indication signal, and the indication signal is used to indicate that the socket is in an energized state or a de-energized state.

[0058] The induction recognition circuit 110 can generate a control signal according to the induction signal. And the induction recognition circuit 110 can transmit the control signal to the indication circuit 130, so that the indication circuit 130 can obtain the control signal.

[0059] Wherein, the control signal is used to control whether the indication circuit 130 works. For example, when the control signal is at a high level, the control signal can control the indication circuit 130 to work, so that the indication circuit 130 can generate an indication signal. For example, when the control signal is at a low level, the control signal can control the indication circuit 130 not to work, so that the indication circuit 130 stops generating the indication signal.

[0060] In this way, the indication circuit 130 can generate an indication signal for indicating that the socket is in an energized state or a de-energized state according to the control signal, so that the user can determine the energized state or de-energized state of the socket based on the indication signal, which is simple and clear.

[0061] Wherein, the indication circuit 130 can be an indicator light, and the indication signal can be used to prompt the user through the light source of the indicator light. For example, when the indicator light is on, the socket is energized. When the indicator light is off, the socket is de-energized. Also for example, when the indicator light is green, the socket is energized, and when the indicator light is red, the socket is de-energized.

[0062] The indication circuit 130 may be a buzzer-like sound generating element. When the sound generating element sounds once, it indicates that the socket is powered off. When the sound generating element sounds twice, it indicates that the socket is powered on. For another example, the sound generating element may emit different sounds to indicate that the socket is powered off or powered on.

[0063] Among them, the indication circuit 130 can be only an indicator light, can be only a sound generating element, or can be a combination of an indicator light and a sound generating element, which is not specifically limited in the embodiment of the present application.

[0064] Based on the description of the above embodiment, a possible implementation of the sensing identification circuit 110 is exemplified. Figure 2 , Figure 2 Show Figure 1 The schematic diagram of the induction recognition circuit. Figure 2 As shown, the induction identification circuit 110 may include: a microprocessor 111, a first resistor R1 and an infrared emitting diode RLED1.

[0065] The microprocessor 111 is integrated with an infrared receiving tube, thereby eliminating the need for an external infrared receiving tube circuit.

[0066] The first pin VLEDC4 of the microprocessor 111 is electrically connected to the cathode of the infrared emitting tube RLED1, the anode of the infrared emitting tube RLED1 is electrically connected to the first end of the first resistor R1, the second end of the first resistor R1 is used to access the power supply voltage, and the second pin PA1 of the microprocessor 111 is electrically connected to the input end of the driving circuit 120.

[0067] The infrared emitting tube RLED1 can send out a detection signal, and the detection signal is used to detect whether the user triggers a body movement.

[0068] The microprocessor 111 can receive the detection signal through an infrared receiving tube, which can significantly reduce the impact of electromagnetic radiation on the user compared to microwave induction. In addition, the microprocessor 111 can generate and identify the induction signal according to the detection signal to obtain the driving signal CONT1.

[0069] Specifically, the microprocessor 111 can obtain the driving signal CONT1 by using an internally integrated register, which can avoid the problem of misjudgment of interference compared to the determination of a traditional analog-to-digital converter ADC.

[0070] The power supply voltage is, for example, +5V.

[0071] When the control circuit 100 of the socket further includes: an indication circuit 130 , the sixth pin PB1 of the microprocessor 111 and / or the seventh pin PA0 of the microprocessor 111 are electrically connected to the input end of the indication circuit 130 .

[0072] Among them, the microprocessor 111 is, for example, a YIR32F0270 main control chip. The YIR32F0270 is a microprocessor with a high-performance 32-bit kernel.

[0073] Among them, by adopting the microprocessor 111 of the YIR32F0270 main control chip, the stability of the control circuit 100 of the socket can be greatly enhanced, and the influence of environmental factors such as infrared recognition light reception can be reduced.

[0074] Alternatively, the microprocessor 111 can control the emission power of the infrared emitting tube RLED1, improve the detection intensity of the detection signal, increase the distance at which the microprocessor 111 senses the triggering of limb movements, and improve the sensitivity.

[0075] In some examples, the induction recognition circuit 110 may further include: a linear voltage regulator 112.

[0076] The input end of the linear voltage regulator 112 is used to connect to the power supply voltage, and the output end of the linear voltage regulator 112 is electrically connected to the third pin VCC of the microprocessor 111.

[0077] The linear voltage regulator 112 can step down the power supply voltage to obtain a supply voltage.

[0078] Among them, the supply voltage is used to supply power to the microprocessor 111.

[0079] Among them, the supply voltage is, for example, +3V.

[0080] In some examples, the induction recognition circuit 110 may further include: a download terminal J1 and a debugging terminal J3.

[0081] The download terminal is electrically connected to the fourth pin SWCLK / SWDIO of the microprocessor 112, and the debugging terminal J3 is electrically connected to the fifth pin RXD / TXD of the microprocessor 112.

[0082] The download terminal J1 is used to download the program stored in the microprocessor 112.

[0083] The debugging terminal J3 is used to debug the microprocessor 112.

[0084] In some examples, the induction recognition circuit 110 may further include: a fifth capacitor C5 and a sixth capacitor C6.

[0085] The first plate of the fifth capacitor C5 is electrically connected to the output end of the linear voltage regulator 112, the first plate of the sixth capacitor C6 is electrically connected to the input end of the linear voltage regulator 112, and the second plates of the fifth capacitor C5 and the sixth capacitor C6 are both grounded.

[0086] Based on the description of the above embodiments, exemplarily, a possible implementation of the driving circuit 120. Refer to Figure 3 , Figure 3 shows Figure 1 a schematic structural diagram of the driving circuit in Figure 3 As shown, the driving circuit 120 may include: a second resistor R2, a transistor K, and a relay 112.

[0087] The first end of the second resistor R2 is electrically connected to the first output end of the induction recognition circuit 110, the second end of the second resistor R2 is electrically connected to the control end of the transistor K, the first end of the transistor K is electrically connected to the first end of the relay 112, the second end of the relay 112 is used to access the power supply voltage, the third end of the relay 112 is electrically connected to the live wire L, the fourth end of the relay 112 is electrically connected to the load end LOUT1, and the second end of the transistor K is grounded.

[0088] In some examples, the driving circuit 120 may further include: a first diode D1.

[0089] The positive electrode of the first diode D1 is electrically connected between the first end of the transistor K and the first end of the relay 112, and the negative electrode of the first diode D1 is used to access the power supply voltage.

[0090] Among them, the relay 112 can be protected by the first diode D1, and the service life of the relay 112 can be extended.

[0091] In some examples, the transistor K is a triode. The base of the triode is the control end of the transistor K, the emitter of the triode is the second end of the transistor K, and the collector of the triode is the first end of the transistor K.

[0092] Among them, through the triode, the power consumption and cost of the driving circuit 120 are relatively low, and thus, the power consumption and cost of the control circuit 100 of the socket can be reduced.

[0093] Exemplarily, when the driving signal CONT1 is at a high level, the transistor K is turned on, causing the relay 112 to be attracted, so that the load end LOUT1 and the live wire L are turned on. Thus, the socket is powered on. When the driving signal CONT1 is at a low level, the transistor K is turned off, causing the relay 112 to be closed, so that the load end LOUT1 and the live wire L are turned off. Thus, the socket is powered off.

[0094] Based on the description of the above embodiments, exemplarily, a possible implementation of the control circuit 100 of the socket. As Figure 1 shown, the control circuit 100 of the socket may further include: a power supply circuit 140.

[0095] The input end of the power circuit 140 is used to receive alternating current AC, and the output end of the power circuit 140 is electrically connected to the power end of the induction recognition circuit 110 and the power end of the driving circuit 120 respectively.

[0096] The power supply circuit 140 can perform an AC-DC conversion process on the alternating current AC to obtain a power supply voltage, and the power supply voltage is used to supply power to the induction recognition circuit 110 and the driving circuit 120 .

[0097] The alternating current AC is, for example, AC220V / 50HZ.

[0098] Based on the description of the above embodiment, a possible implementation of the power supply circuit 140 is exemplified. Figure 4 , Figure 4 Show Figure 1 The schematic diagram of the power supply circuit in FIG. Figure 4 As shown, the power circuit 140 may include: a second diode D2, a buck converter chip 141, a first inductor L1, a second inductor L2, a first capacitor C1, a second capacitor C2, a third capacitor C3 and a fourth capacitor C4.

[0099] The anode of the second diode D2 is electrically connected to the first terminal AC-L, the first end of the first inductor L1 and the first plate of the first capacitor C1 are both electrically connected to the cathode of the second diode D2, the second end of the first inductor L1 is electrically connected to the first plate of the second capacitor C2 and the first pin C of the buck converter chip 141 respectively, the second pin ICG of the buck converter chip 141 is electrically connected to the first end of the second inductor L2, the third pin VCC of the buck converter chip 141 is electrically connected to the first plate of the fourth capacitor C4, the second plate of the fourth capacitor C4 is electrically connected between the second pin ICG of the buck converter chip 141 and the first end of the second inductor L2, the fourth pin VCC of the buck converter chip 141, the second end of the second inductor L2 and the first plate of the third capacitor C3 are all used to output the power supply voltage, and the second plate of the first capacitor C1, the second plate of the second capacitor C2, the second plate of the third capacitor C3 and the fifth pin GND of the buck converter chip 141 are all electrically connected to the second terminal AC-N.

[0100] The buck converter chip 141 is, for example, a LP2188A chip. Thus, compared with an isolated switching power supply, the power circuit 140 is smaller in size, so that the control circuit 100 of the socket is smaller in size. Thus, the control circuit 100 of the socket can be installed in an 86-box socket.

[0101] The second diode D2 is used as a half-wave rectifier diode.

[0102] Among them, the first inductor L1, the second inductor L2, the first capacitor C1, the second capacitor C2, and the third capacitor C3 play a role in step-down filtering.

[0103] In some examples, the power supply circuit 140 may further include: a third resistor R3, a fuse FR1, and a fourth resistor ZR1.

[0104] The first end of the third resistor R3 is electrically connected to the second end of the second inductor L2. The first end of the fuse FR1 is electrically connected to the first terminal AC-L. The second end of the fuse FR1 is respectively electrically connected to the first end of the fourth resistor ZR1 and the cathode of the second diode D2. The second ends of the third resistor R3 and the fourth resistor ZR1 are both electrically connected to the second terminal AC-N.

[0105] Among them, the fuse FR1 plays a role in protecting the power supply circuit 140, and the fourth resistor ZR1 plays a role in surge protection. Exemplarily, the fuse FR1 is, for example, a fuse.

[0106] The embodiment of the present application also provides a socket, and the socket includes: the control circuit of the socket provided by the embodiment of the present application.

[0107] The socket provided by the embodiment of the present application has the same beneficial effects as the control circuit of the socket provided by the embodiment of the present application, which will not be elaborated here.

[0108] Among them, the socket may include but is not limited to: flush-mounted sockets, surface-mounted sockets, track socket adapters, mobile sockets, converter sockets, extension cord sockets, and appliance sockets.

[0109] Among them, the socket may include but is not limited to socket strips, converter sockets, track adapter sockets, and sockets for small household appliances such as table lamps.

[0110] Exemplarily, in an application scenario where a user with special needs cannot find the socket position of the electrical plug, when the electrical plug is inserted into the socket, since the user with special needs cannot accurately identify the plug position, it is inconvenient to plug and unplug the plug. Thus, the user with special needs only needs to know the approximate position of the socket, and the user with special needs can trigger a body movement such as waving, so that the control circuit of the socket can control the power-off and power-on of the socket based on the body movement to control the power-off and power-on of the electrical appliance. Thereby, the convenience of using the electrical appliance by the user with special needs is improved. Among them, the power-on state or power-off state of the socket can be prompted by an indication signal that can emit sound.

[0111] Exemplarily, in an application scenario where a user in a special group is unable to plug or unplug a plug, when an electrical appliance plug is inserted into a socket and the user in the special group is unable to plug or unplug the plug, the user in the special group only needs to trigger a body movement such as waving an arm or kicking a leg towards the socket to achieve power-off and power-on of the electrical appliance socket. Thus, the usability of the electrical appliance for the user in the special group is improved. Among them, the power-on and power-off of the socket can be prompted by an indication signal that can emit sound and / or light.
