Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them.

With the continuous progress of science and technology, the concept of intelligent switch starts to enter thousands of households, and due to the unique intelligent control, a plurality of consumers are attracted. Existing intelligent switches typically include at least a switch module and a control module. The switch module is electrically connected with a load, the load can be household appliances such as a lighting lamp, and when the switch module is communicated, the load works normally. When the switch module is turned off, the load stops working. The control module can control the on-off state of the switch module, and further control the working state of the load. The control module is required to ensure that the control module always keeps normal power supply to realize the on-off state of the control switch module. Therefore, the control module and the switch module need to be in two different loops, so that the control module is normally powered no matter the switch module is in a connected or disconnected state.
Fig. 1 shows a schematic structure diagram of an intelligent switching circuit applied to a zero-live wire environment in the prior art.
Most of the existing intelligent switches are suitable for the zero-live line circuit environment. In the zero-live line circuit environment, the zero-live line wiring position is reserved at the position of the connection switch during the decoration and wiring, as can be seen from fig. 1, in the zero-live line circuit environment, the main brake module 600 is connected with the live line L of the external power supplyOuter coverZero line NOuter coverAnd ground wire PEOuter coverThe power is obtained from an external power source. In order to ensure the safety of electricity, the outlet protection switch module 500 is generally disposed between the outlet 300 and the main gate module 600. The socket protection switch module 500 is connected to the ground line PE, the live line L and the neutral line N of the bus bar module 600, and the socket 300 is connected to the ground line PE1, the live line L1 and the neutral line N1 of the socket protection switch module. To ensure electrical safety, the socket protection switch module 500 typically includes an air switch that automatically opens to protect the circuit when the current in the circuit exceeds a safety threshold. In addition to the air switch, the socket protection switch module 500 generally includes a leakage switch. The leakage switch is used for automatically disconnecting to protect the safety of the circuit when the circuit is short-circuited, leaked or unbalanced in current. To ensure electrical safety, a lighting protection switch module 400 is typically provided between the prior art intelligent switch 100' and the main brake module 600. The lighting protection switch module 400 is connected to the live wire L and the neutral wire N of the main brake module 600, and the live wire end and the neutral wire end of the power supply module of the intelligent switch 100' in the prior art are electrically connected to the live wire L2 and the neutral wire N2 of the lighting protection switch module, respectively. Since the switch module of the prior art intelligent switch 100' passes through in the zero line and live line circuit environmentThe lamp wire D is connected to a neutral wire connection portion reserved in the decoration wiring after being connected to the illumination lamp 200, and is thus electrically connected to the second neutral wire N2 of the illumination protection switch module. The control module of the prior art intelligent switch 100 'is powered by the power supply module, so that the control module and the switch module of the prior art intelligent switch 100' are respectively located in two different loops, and the control of the lighting lamp 200 can be realized.
However, even though most of the newly-finished houses now adopt the zero-fire line circuit environment, a large proportion of the wiring environment of the previously-finished houses is still the single-fire line circuit environment. The one-live line circuit environment means that no zero line wiring position is reserved at the position of the switch when the wiring is finished, that is, if the intelligent switch of the prior art shown in fig. 1 is applied to the one-live line circuit environment, no zero line wiring position can be connected to the circuit loop after the switch module is electrically connected with the illuminating lamp 200 through the lamp wire D.
Based on this, in order to make the intelligent switch also be applicable to single live wire scene, prior art can adopt two kinds of schemes usually. The first solution is to add a zero line to the home wiring so that the switch module can form an independent loop. The first scheme needs to reform the household wiring environment again, needs to open the wall again for wiring, and is high in cost and relatively troublesome.
Fig. 2 shows a schematic structure diagram of an intelligent switch applied to a single-live-wire environment in the prior art.
Referring to fig. 2, a second scheme is to electrically connect the neutral terminal of the prior art intelligent switch 100' with the illumination lamp 200 through the lamp wire D. However, in this configuration, the control module of the related art smart switch 100 'is connected in series with the illumination lamp 200, and when the illumination lamp 200 is turned off, the control module of the related art smart switch 100' also turns off the power supply, and the control module that turns off the power supply cannot control the illumination lamp 200 to be turned on again.
In order to solve the above-mentioned problems, the inventors of the present invention have continued to research and design a new circuit so that the circuit can be applied to both the zero line and single line application scenarios to solve the above-mentioned technical problems of the prior art. Based on this, the inventor has provided an intelligence live wire switch circuit, in this intelligence live wire circuit, the first end with power module is independent with switch module's second end, optionally carry out the electricity with one of them of the live wire of power module's first end and second power under different application scenes through virtual connection module, make intelligence switch circuit can compatible zero live wire application scene and single live wire application scene, relative above-mentioned two kinds of schemes, need not to add the zero line, avoid reforming transform the family wiring environment again, the wiring problem that control module need be located two different return circuits with the light has also been solved.

Referring to fig. 3c, when the intelligent switch circuit according to the embodiment of the present application is applied to a single live wire scene, since no zero line wiring is reserved at the switch wiring position in the single live wire scene, the intelligent switch circuit cannot be electrically connected to the zero line at the switch wiring position. First, in the present embodiment, the first external power source includes a first live line L1 and a first neutral line N1, and the second external power source includes a second live line L2 and a second neutral line N2.

The application also provides an intelligent switch control system. The system includes the intelligent switching circuit 100 described above and a load. A first end of the load is electrically connected to a first end of the switch module 10. The load may be a smart home device, such as an air conditioner, a refrigerator, a television, an electric light, a motorized window shade, a projection device, and the like, which is not limited in this application.
The intelligent switch control system can be applied to a zero-fire wire environment and a single-fire wire environment, and the working principle of the intelligent switch control system is explained below aiming at two different application scenes.
Specifically, when the intelligent switch control system of the embodiment of the application is applied to a zero-live wire scene, the zero line can be directly electrically connected with the zero line of the switch wiring position from the switch wiring position under the zero-live wire scene. First, in the present embodiment, the first external power source includes a second live line L2 and a second neutral line N2, the first end 10a of the power supply module 10 is electrically connected to the second live line L2, and the second end 10b of the power supply module 10 is electrically connected to the second neutral line N2. Specifically, the second end 40b of the virtual connection module 40 of the embodiment of the present application is electrically connected to the first end 10a of the power supply module 10, and the first end 20a of the switch module 20 is electrically connected to the load and then returns to the second neutral line N2. The control module 30 forms a loop with a second neutral conductor N2 and a second live conductor L2. The switch module 20 forms a further circuit with a second neutral line N2 and a second live line L2. The two circuits are independent of each other, so that when the switch module 20 is turned off, the control module 30 can normally obtain power from the first live line L1 and the first neutral line N1 for normal operation. The currents in the first neutral conductor N1 and the first live conductor L1 are also balanced because the current flows from the first live conductor L1 through the power module 10 and back out the first neutral conductor N1. The current flows from the second live line L2 through the switch module 20 and back from the second neutral line N2. Thus, the current in the circuit is balanced and does not cause a trip.
Specifically, when the intelligent switch circuit of the embodiment of the application is applied to a single live wire scene, no zero line wiring is reserved from the switch because of the single live wire scene, and the intelligent switch circuit cannot be directly connected with a zero line at the switch. First, in the present embodiment, the first external power source includes a first live line L1 and a first neutral line N1, and the second external power source includes a second live line L2 and a second neutral line N2. The first end 10a of the power supply module 10 is electrically connected to the first live line L1, and the second end 10b of the power supply module 10 is electrically connected to the first neutral line N1. Specifically, the second end 40b of the virtual connection module 40 of the embodiment of the present application is electrically connected to the second live line L2. It should be noted that the second power line L2 and the first power line L1 are power lines located in different loops, the first power line L1 may be a power line at a socket, and the second power line L2 may be a power line at a switch, which is not limited in this application. As an embodiment, the power supply module 10 may be electrically connected with the first live line L1 and the first neutral line N1 of the socket. The second end 40b of the virtual connection module 40 can be electrically connected to the second live line L2 of the switch adjacent to the socket, and in other embodiments, can be electrically connected to other wiring places, as long as it is ensured that the power supply module 10 can be electrically connected to the zero live line, the virtual connection module 40 can be electrically connected to the live line, and the power supply module 10 and the live line connected to the virtual connection module 40 belong to different wiring places. Further, the second end 40b of the virtual connection module 40 is connected to the second live line L2, and the first end 20a of the switch module 20 is electrically connected to the load 200 and then electrically connected to the second neutral line N2. The switch module 20 forms a loop with the second live wire L2 and the second neutral wire N2, and the control module 30 forms a loop with the first live wire L1 and the first neutral wire N1. The two circuits are independent of each other, so that when the switch module 10 is turned off, the control module 30 can normally obtain power from the first live line L1 and the first neutral line N1 for normal operation. The currents in the first neutral conductor N1 and the first live conductor L1 are also balanced because the current flows from the first live conductor L1 through the power module 10 and back out the first neutral conductor N1. The current flows from the second live line L2 through the switch module 20 and back from the second neutral line N2. Therefore, the currents of the circuit in which the first live line L1 and the first neutral line N1 are located are balanced. The currents of the currents in the second live line L2 and the second neutral line N2 are also balanced. Therefore, the problem of tripping caused by unbalanced current when the intelligent switch is applied to a single live wire scene is solved.
The intelligent switch control system provided by the application is independently opened by the first end 10a of the power supply module 10 and the second end 20b of the switch module 20, and the second end 40b of the virtual connection module 40 is selectively and electrically connected with one of the first end 10a of the power supply module 10 and the live wire of the second external power supply under different application scenes, so that the intelligent switch control system can be compatible with a zero-live-wire application scene and a single-live-wire application scene, and popularization and use of the intelligent switch are greatly promoted.
The application also provides an intelligent switch. The intelligent switch includes a housing and the intelligent switch circuit 100 described above. Since the operation mode of the intelligent switch in this embodiment is the same as that of the intelligent switch circuit, the details are not repeated here.
