[0002] With the widespread use of electricity in homes, the safety of household electricity use is becoming increasingly important.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0023] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0024] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0025] As disclosed in the background, existing sockets pose a risk of electric shock from children accidentally touching the switch. While some sockets incorporate safety door designs, this still doesn't fundamentally address the risk of electric shock from children accidentally touching the switch. Furthermore, existing sockets also fail to prevent the socket from automatically shutting off when pets or children approach while in use, negatively impacting the user experience.

[0026] In order to solve the above problems, an embodiment of the present invention provides a new type of safety induction socket. It should be noted that the features in the embodiments of the present invention can be combined with each other if there is no conflict.

[0027] The safety induction socket provided in the embodiment of the present invention can effectively prevent children from accidentally touching the switch and causing the risk of electric shock, and can also prevent the power from being accidentally disconnected when the socket is in use, thereby protecting electricity safety without affecting the user experience.

[0028] See also Figures 1 to 4 The safety induction socket 100 provided in an embodiment of the present invention includes a socket body 110, a current detection device 120, an infrared sensor device 130, and a power-off control device 140. The back of the socket body 110 is used to connect to a wall or a wall socket, and the front of the socket body 110 is provided with a socket 111 for inserting a load-side plug. The current detection device 120 is disposed within the socket body 110 and is configured to detect the current signal of the socket body 110; the infrared sensor device 130 is disposed on the front of the socket body 110 and is configured to detect a heat source blocking signal on the front of the socket body 110; the power-off control device 140 is disposed within the socket body 110 and is in communication with both the current detection device 120 and the infrared sensor device 130. It is configured to control the power on and off of the socket body 110. The power-off control device 140 is configured to control the power off of the socket body 110 when the current detection device 120 does not detect a current signal and the infrared sensor device 130 detects a heat source blocking signal.

[0029] It should be noted that the power-off control device 140 here can only control the power supply of the socket body 110 to be cut off when the current detection device 120 does not detect a current signal and the infrared sensor device 130 detects a heat source blocking signal, and controls the power supply of the socket body 110 in other situations. Therefore, the embodiment of the present invention, by additionally designing the current detection device 120 and using the current detection device 120 to detect the current signal, determines whether a load electrical appliance is in use. When no load electrical appliance is in use and a child or pet (heat source) is near the socket body 110, the power supply can be cut off by the power-off control device 140. This can effectively prevent the risk of electric shock caused by children accidentally touching the switch, and also prevent accidental power off during use, thereby protecting electrical safety without affecting the user experience.

[0030] It is worth noting that the current detection device 120 here can be a current sensor, model BL0942 / SSOP10L or LF1005-S, both of which are existing models. The specific detection circuit is as follows: Figure 9 The current detection device 120 can detect the current signal of the socket body 110 in real time, thereby obtaining the working status of the socket body 110 in real time. When the load electrical appliance is plugged into the socket 111 and working, the current signal is detected, otherwise no current signal is detected.

[0031] In some embodiments, the power-off control device 140 is electrically connected to the infrared sensor device 130 and is further configured to control the infrared sensor device 130 to power off when the current detection device 120 detects a current signal. Specifically, the infrared sensor device 130 can detect heat source blocking signals in real time. When a heat source (such as a child or pet) approaches the front of the socket body 110, the infrared sensor device 130 can detect the heat source blocking signal; otherwise, no heat source blocking signal is detected. The infrared sensor device 130 can be powered off when the current detection device 120 detects a current signal, preventing it from continuing to detect the heat source blocking signal. This effectively prevents accidental power-off when a load electrical appliance is operating on the socket body 110, which could affect the user experience.

[0032] It should be noted that if the power-off control device 140 is capable of controlling the infrared sensor device 130 to power off, the power-off control device 140 can control the power on or off of the socket body 110 solely based on the heat source shielding signal, making the control logic simpler and more reliable. In actual use, when a load plug is inserted into the socket 111 and is in operation, the current detection device 120 detects a current signal. At this time, the power-off control device 140 can directly control the infrared sensor device 130 to power off, and the socket body 110 remains energized. When no plug is inserted into the socket 111 or the inserted plug is not in operation, the current detection device 120 does not detect a current signal. At this time, the power-off control device 140 needs to control the power on and off of the socket body 110 based on the detection result of the infrared sensor device 130. Among them, when the infrared sensor device 130 detects a heat source blocking signal, it means that there is a heat source approaching the socket body 110. At this time, the socket body 110 is powered off for a preset time (such as 3s) under the control of the power-off control device 140 and then re-judged. When the infrared sensor device 130 does not detect a heat source blocking signal, it means that there is no heat source approaching the socket body 110. At this time, the socket body 110 remains powered on.

[0033] See also Figure 4 and Figure 5 In some embodiments, the power-off control device 140 includes a controller 141 and a power-off module 143. The controller 141 is in communication with the infrared sensor device 130 and the current detection device 120 at the same time. The power-off module 143 is electrically connected to the controller 141. The controller 141 is configured to generate a power-off signal when the infrared sensor device 130 detects a heat source blocking signal, and to control the infrared sensor device 130 to power off when the current detection device 120 detects a current signal. The power-off module 143 is configured to control the socket body 110 to power off according to the power-off signal. Specifically, the controller 141 can be an MCU module, whose model is TSSOP20 or STM32G071RB. The circuit of the MCU is as follows: Figure 10As shown, the power-off module 143 is a relay, model G2R-2-SND, and the circuit of the relay is as follows: Figure 11 The relay can be a normally closed relay, and the power-off signal can be a high-level signal, so that the relay is disconnected for a preset time (such as 3 seconds) and the socket body 110 is in a power-off state, avoiding the occurrence of false touches. After the preset time, the controller 141 re-judges the state.

[0034] It should be noted that, in this embodiment, the socket body 110 is in the power-on state, which means that the relay is in a continuously attracted state, and the socket body 110 is in the power-off state, which means that the relay is in the disconnected state.

[0035] In some embodiments, the infrared sensing device 130 includes an infrared distance sensor 131, which is disposed on the front surface of the socket body 110 and is configured to detect a heat source within a preset distance from the front surface of the socket body 110 and generate a heat source obstruction signal. Specifically, the infrared distance sensor 131 can be configured to determine the presence and distance of a heat source. Upon detecting a heat source within a preset distance range, a heat source obstruction signal can be generated, i.e., a heat source obstruction detection signal. The infrared distance sensor 131 can integrate the functions of infrared sensing and distance sensing, resulting in a higher level of integration.

[0036] Furthermore, the preset distance is less than or equal to 20 cm, and preferably can be 10 cm, that is, the heat source blocking signal will be detected only when the heat source enters within 10 cm of the front of the socket body 110, which can effectively avoid the situation where the heat source causes power outages during normal activities in the room. Of course, the preset distance can be adjusted according to different scenarios.

[0037] It should be noted that the socket body 110 also includes a rectifier bridge circuit, which steps down the 220V voltage to 5V to power the infrared distance sensor 131. When the infrared distance sensor 131 detects an approaching heat source within a preset distance (e.g., 20cm), the controller 141 / O port outputs a high level, disconnecting the power-off module 143 (relay). At this point, the socket body 110 is powered off, preventing accidental touches. If the infrared distance sensor 131 does not detect an approaching heat source within a specified distance, the I / O port remains silent, and the socket body 110 remains powered on. Furthermore, if the current detection device 120 detects current flowing through the socket body 110, the infrared distance sensor 131 is shielded (power-off mode), preventing the socket body 110 from automatically powering off while in use, potentially impacting the user's experience.

[0038] It is worth noting that the socket 111 on the socket body 110 in this embodiment can be a five-hole structure, including a three-hole structure and a two-hole structure. In some preferred embodiments, the electrical control design within the socket body 110 can be used to selectively power on either the three-hole structure or the two-hole structure. For example, when a load product is inserted into the three-hole structure, the two-hole structure automatically powers off, and vice versa, when a load product is inserted into the two-hole structure, the three-hole structure automatically powers off.

[0039] See also Figure 6 In some other embodiments of the present invention, the heat source blocking signal includes a heat source signal and a gesture signal. The infrared sensing device 130 includes an infrared sensor 133 and a gesture sensor 135. Both the infrared sensor 133 and the gesture sensor 135 are located on the front of the socket body 110 and extend into the socket body 110. The infrared sensor 133 is configured to detect heat source signals from the front of the socket body 110, and the gesture sensor 135 is configured to detect gesture signals from the front of the socket body 110. Specifically, the infrared sensor 133 can be a sensor that detects heat sources, such as infrared rays emitted by a human body. The gesture sensor 135 can be a visual sensor capable of recognizing gestures made by a person or pet, such as a hand reaching toward the socket body 110. The infrared sensor 133 and the gesture sensor 135 are both located on one side of the socket 111 (either top, bottom, left, or right) and are at least partially embedded in the socket body 110. The controller 141 is electrically connected to both the infrared sensor 133 and the gesture sensor 135 to determine whether a child accidentally touches a switch, posing a risk of electric shock. When the infrared sensor 133 detects a heat source signal and the gesture sensor 135 detects a predetermined gesture, the controller 141 determines that a suspected child is approaching and touching the socket body 110 , and controls the power-off module 143 to cut off the power to the socket body 110 .

[0040] It should be noted that to avoid the problem of the socket automatically being powered off when a pet or child approaches while an electrical load is in use on the socket body 110, the infrared sensor 133 and gesture sensor 135 are both in power-off mode when the socket body 110 is in operation. That is, the controller 141 can control the infrared sensor 133 and gesture sensor 135 to power off when the current detection device 120 detects a current signal. Only when the socket body 110 is idle do the infrared sensor 133 and gesture sensor 135 begin to detect whether there is an accidental touch. The additional design of the gesture sensor 135 makes power-off control more precise. Only a predetermined gesture by a child or pet can trigger the power off, eliminating interference from other heat sources, such as heat source interference from a sweeping robot or lamp.

[0041] Please continue to see Figures 1 to 4 、 Figure 7 and Figure 8In some embodiments, the socket body 110 includes a socket shell 150, a socket assembly 160 and an electric control board 170. The electric control board 170 and the socket assembly 160 are both arranged in the socket shell 150. The current detection device 120 is arranged in the socket shell 150 and is located on the electric control board 170. It is configured to detect the current signal passing through the electric control board 170. The socket assembly 160 corresponds to the jack 111 and is configured to electrically contact the load plug inserted into the jack 111. The infrared sensor device 130 is arranged on the side of the electric control board 170 close to the jack 111, and an avoidance hole for partially exposing the infrared sensor device 130 is provided on the front of the socket shell 150. The power-off control device 140 is arranged on the electric control board 170 and is configured to control the power on and off status between the bent socket 163 and the electric control board 170. Specifically, the electrical control board 170 can be a PCBA circuit board, connected to the socket assembly 160 via wires. The controller 141 and the power-off module 143 are both mounted on the electrical control board 170. The socket housing 150 is rectangular, with its back facing the wall and its front exposed. The infrared sensor 130 can be partially exposed within the socket housing 150, facilitating detection of heat source blocking signals.

[0042] In some embodiments, the socket assembly 160 includes a support plate 161, a bent socket 163, and a safety door 165. The support plate 161 is provided with a through hole corresponding to the socket 111. The bent socket 163 is disposed on the side of the support plate 161 away from the socket 111 and extends to the through hole. The safety door 165 is disposed on the side of the support plate 161 near the socket 111 and is configured to block the through hole when the load-side plug is not inserted into the socket 111. Specifically, the support plate 161 is made of insulating material, the bent socket 163 is a copper socket, and a support frame is further provided on the side of the support plate 161 near the socket 111. The safety door 165 is embedded and fixed in the support frame. The safety door 165 has a certain degree of elasticity and a guiding slope. When the plug is not inserted into the socket 111, the safety door 165 can block the through hole, thereby blocking the socket 111 from the through hole and preventing accidental contact. When the plug is inserted into the socket 111 , the plug can abut against the guide slope of the safety door 165 , push the safety door 165 to deform, and then be inserted into the through hole, and make electrical contact with the bent socket 163 to achieve electrical connection.

[0043] It should be noted that the bending shape and number of the bent sockets 163 in this embodiment are related to the distribution of the sockets 111. In this embodiment, a five-hole socket is used as an example. Of course, in other preferred embodiments, the sockets 111 can also be distributed in other forms such as 2 holes, 3 holes, or 7 holes.

[0044] Furthermore, the socket body 110 also includes a support plug 180, which is arranged on the side of the socket assembly 160 away from the socket 111 and partially extends out of the back of the socket shell 150. The support plug 180 is electrically connected to the electric control board 170. The part of the support plug 180 that passes through the back of the socket shell 150 can be plugged into a conventional wall plug, thereby achieving better applicability with conventional plugs. At the same time, the support plug 180 can also play a role in supporting the entire socket body 110, so the part of the support plug 180 accommodated inside the socket shell 150 can maintain a fixed electrical connection with the socket body 110. Among them, the support plug 180 is a three-plug structure, and its ground wire and neutral wire can be directly connected to the E pole and L pole of the socket, and the live wire is connected to the electric control board 170 for control. Furthermore, in order to ensure electrical isolation between the support plug 180 and the socket assembly 160 , a partition 169 may be provided in the socket housing 150 . The partition 169 is provided between the support plug 180 and the socket assembly 160 , thereby ensuring good electrical isolation.

[0045] In other preferred embodiments of the present invention, the design of the supporting plug 180 may be omitted, and the circuit board may be directly connected to the external circuit, so that the safety induction socket 100 has a wall plug structure.

[0046] In some embodiments, an indicator light 113 is further provided on the front of the socket housing 150. The indicator light 113 is electrically connected to the electrical control board 170 and is configured to illuminate when power is supplied between the bent socket 163 and the electrical control board 170. Specifically, when the indicator light 113 illuminates, it indicates that the socket body 110 is powered on; when the indicator light 113 is off, it indicates that the socket body 110 is powered off. The indicator light 113 can be directly controlled by the controller 141 or by a current detection device.

[0047] The safety induction socket 100 provided in an embodiment of the present invention operates as follows: 220V mains power is stepped down to 5V via a rectifier bridge and then used to power the current detection device 120 and infrared sensor device 130. A current signal determination is first performed. If the current detection device 120 detects a current signal, the controller 141 does not operate, the relay remains closed, and the socket body 110 remains powered. If the current detection device 120 does not detect a current signal, an infrared blocking signal determination is performed. If the infrared sensor device 130 detects an infrared blocking signal, the controller 141 controls the relay to disconnect for a preset time, thereby disconnecting the socket body 110 from power for a preset time (e.g., 3 seconds). If the infrared sensor device 130 does not detect an infrared blocking signal, the controller 141 does not operate and performs a current signal determination again. At this time, the socket body 110 remains powered.

[0048] In summary, the safety induction socket 100 provided in this embodiment has a socket 111 disposed on the front face of the socket body 110, and a current detection device 120 disposed within the socket body 110. This current detection device 120 is capable of detecting the current signal of the socket body 110, thereby providing a basis for determining whether a load electrical appliance is in use. Furthermore, an infrared sensor device 130 is disposed on the front face of the socket body 110, capable of detecting a heat source obstruction signal from the front face of the socket body 110, thereby providing a basis for determining whether a child or pet is approaching. A power-off control device 140 is disposed within the socket body 110 and is in communication with both the current detection device 120 and the infrared sensor device 130, thereby controlling the power on and off of the socket body 110. Specifically, the power-off control device 140 can control the power off of the socket body 110 when the current detection device 120 detects no current signal and the infrared sensor device 130 detects a heat source obstruction signal. This means that the power will be turned off only when a child or pet (heat source) approaches and no load electrical appliance is in use. Compared with the prior art, the safety induction socket 100 provided in the embodiment of the present invention has an additional current detection device 120, and the current detection device 120 detects the current signal to determine whether a load electrical appliance is in use. When no load electrical appliance is in use and a child or pet (heat source) is close to the socket body 110, the power can be cut off by the power-off control device 140.
