In order to make the objects, the technical solutions and the advantages of the present invention more comprehensible, the present invention will be described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

1 is a circuit diagram of a smart anti-shock socket of the present invention, the wrist of the smart anti-shock socket includes at least one pyroelectric infrared sensor 10, at least one detection switch 20, at least one relay output module 30, a control module 40, and Power module 50, wherein

The pyroelectric infrared sensor 10 is connected to the control module 40 for detecting whether a person is present around the socket in the range of the pyroelectric infrared sensing range, and the person will be invited to the control module 40. Depending on the sensing range, different infrared sensors can be selected to meet different needs.

The detection switch 20 is connected to the control module 40 for detecting whether the jack group is plugged in, and the information is transmitted to the control module 40. For a three-hole socket that includes an N-hole (zero-line jack) 60 or L-hole (firewire jack) 70 and an E-hole (protective ground jack) 80, as shown in Figures 2 and 3, there are sometimes conductors. When entering the N hole 60 or the L hole 70, there are cases where three holes are inserted into the conductor or the plug due to an erroneous operation. When the detecting switch 20 detects a certain insertion condition, the information is controlled by the control module 40.

The relay output module 30 has one end connected to the control module 40, and the N-holes 60 respectively connected to the plugs Connected to the L-hole 70, the relay output module 30 is controlled by the control module 40 for receiving the command of the control module 40 to control the on and off of the socket power supply. The relay output module 30 of the present invention includes an isolation relay having a strong electrical and electrical isolation characteristic, that is, the ^^ electrical hole is isolated from the relay when not inserted. In the non-operating state, the electrical holes are not charged. When a plug is inserted, the N hole 60, the L hole 70 and the touch point of the socket realize the logic and the isolation relay operates to make the plug supply power normally. When the plug is inserted, the circuit is automatically reset to the electrical isolation state.

The control module 40 is the main component of the electric system, and the receiver stores the information and inserts the information and performs the processing analysis. When the N hole 60 and the L hole 70 are known to be inserted, the M hole and the L hole 70 are simultaneously inserted into the seat. When there is no human body around, the control module 40 controls the relay output module 30 to turn on the power of the jack group, otherwise the control relay output module 30 turns off the power supply. The control module 40 can employ a single chip microcomputer or an integrated circuit chip, and the present invention is a control unit.

In the crane, the control module 40 knows that the N-hole 60 and the L-hole 70 of the plug-in and the plug-in and the plug-in are not stored, and the relay output module 30 can be controlled at a predetermined time; f3⁄4i?li and the power supply , the time can be scheduled for 1-30 seconds according to different needs. In this way, the power supply is ensured after the presence of the human body, so that the socket is safer and the human body electric shock accident is avoided.

The appearance of the smart anti-shock socket provided by an embodiment of the present invention is as shown in FIG. 2 and FIG. 3 . The shape of the socket can be designed as a circle, a square or a surface according to different requirements, and includes a housing 100 and a leg housing. At least one plug L, each jack lS includes an N hole 60 and an L hole 70, and the third socket further includes an E hole (protecting the female jack) 80. When there is a single conductor because the beach is inserted into the L hole 70 or the N hole 60, the detecting switch 20 transmits the information to the control block 40, under which the pyroelectric infrared sensor 10 detects the human body. Exist, the socket circuit will not turn on. If the operation is made by mistake, the 1" seat N hole 60 and the L hole 70 are simultaneously inserted into the conductor or the plug. At the same time, if the pyroelectric infrared sensor 10 senses the presence of a human body around the socket, the socket circuit will not be turned on. This ensures the birth of the socket.

The smart anti-shock socket of the present invention may include more than two jack sets, as shown in the embodiments of FIGS. 6 and 7. In the socket, the socket 4 should be powered by a certain jack group. If the control module 40 knows the plug ^MWL and the jack and/or the neutral jack according to the input information, the shell is made. Module 40 controls relay output module 30 to turn off plug 1 and power; otherwise, start fiber L and power. Thereby, in the multi-plug l, the jack group that has been working normally is not affected by the other jack group.

More preferably, the smart anti-shock socket of the present invention can also be applied to a fixed socket. In the embodiment shown in Fig. 8, in order to facilitate different occasions, it is possible! The tamper-proof electric shock socket is fixed to the wall, and the structure of the socket is the same as the f3⁄4. Thereby, the invention is inserted into two different forms of applications, the mobile type and the fixed type.

The pyroelectric infrared sensor 10 of the smart anti-shock socket of the present invention is disposed on the socket housing 100, and detects the switch

20. The relay output module 30, the control module 40, and the power module 50 are all disposed in the housing 100. Crane's, ^^ socket|± also has a working state, the light lamp 90, the working state ^ ^ lamp 90 is connected with the control module 40, the light lamp 90 is as shown in Figure 5, the LED0 in the circuit, when the relay output module 30 When the jack group is powered, the control module 40 controls the working state. The lamp 90 displays the first color. When the relay output module 30 turns off the plug 1 and the power is turned on, the control module 40 controls the state of the user. Color, in the embodiment of the present invention, m& is set to the first color, and the second color is set to red. Take the lake to sleep.

4 is a cross-sectional view of an embodiment of the smart anti-electric shock socket of the present invention, the housing 100 of the smart anti-shock socket includes an upper casing 1 and a lower casing #2 fixed to each other, and a joint of the belly casing 1 and the lower casing #2 There is a decorative ring 3 which can make the socket type generous and prevent the casing 1 and the lower casing #2 from coming off. In this embodiment, the detecting open 0 includes the push rod 4, the spring 5 and the pressing 6. The one end of the push rod 4 is respectively associated with the household » spring 5 and the button 6 , and the other end extends to the insert la ^ N hole 60 PL hole 70. When the power is plugged in, the plug pushes the drive push rod 4, and the push rod 4 drives the push rod 4 against the button 6 via the elastic motor 5, and when the power plug is fully inserted, the driver releases the socket to a certain extent, and the pyroelectric infrared sensor 10 does not sense. After the human body, the circuit is turned on, or turned on after a few seconds. The time delay is controlled by the control mode 0, which is determined by the software of the pre-program. Therefore, the length of the delay can be designed according to different needs.

More preferably, in more than two jack group circuit structures, one control module 40 can be used to control the power on and off of two or more sockets. Similarly, multiple plugs can also share the pyroelectric infrared sensor. 10. In the circuit of the embodiment shown in FIG. 5, the two sockets are controlled by a single PIC microcontroller, and only one pyroelectric infrared sensor 10 is used, thereby saving circuit components.
