For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In one implementation, the micro switch of the circuit breaker is only used to detect the state of the circuit breaker and cannot reset the circuit breaker when the power-on abnormal state occurs.

[0033] To solve the above problems, the present application provides a circuit breaker that can accurately detect the circuit breaker status and initialize the power-on anomaly to prevent the control circuit from malfunctioning. Figure 1 and Figure 2 As shown, the circuit breaker provided in the embodiment of the present application includes a housing 10, a transmission mechanism 11, a handle 14 and an operating mechanism 16. A control unit, a first micro switch 12 and / or a second micro switch 13 electrically connected to the control unit are also provided in the housing 10;

[0034] The first micro switch 12 cooperates with the transmission mechanism 11;

[0035] and / or, the second micro switch 13 cooperates with the handle 14;

[0036] The control unit confirms the state of the circuit breaker according to the electrical signal of the first micro switch 12 and / or the second micro switch 13;

[0037] And / or, in the event of a power-on abnormal state, the connection state of the circuit breaker is initialized and reset.

[0038] The electric transmission mechanism 11 , the handle 14 and the operating mechanism 16 are linked in sequence. The electric transmission mechanism 11 drives the handle 14 to rotate, and the handle 14 drives the operating mechanism 16 to open and close the switch.

[0039] Among them, the electric transmission mechanism 11 is connected to the driving device, which can generally be a motor, and the electric transmission mechanism 11 is driven by the motor; and the control unit is electrically connected to the driving device, and the control unit can automatically control the start and stop of the driving device, and then control the electric transmission mechanism 11, the handle 14 and the operating mechanism 16 to realize automatic opening and closing.

[0040] A first micro switch 12 or a second micro switch 13 is also provided in the housing 10, or both the first micro switch 12 and the second micro switch 13 are provided. The first micro switch 12 cooperates with the electric transmission mechanism 11 to control and detect the movement of the electric transmission mechanism 11; and / or the second micro switch 13 cooperates with the handle 14 to control and detect the movement of the handle 14; the first micro switch 12 and / or the second micro switch 13 respectively feed back electrical signals to the control unit, and the control unit uses this to determine the state of the circuit breaker.

[0041] And / or, the first micro switch 12 and / or the second micro switch 13 can also drive the circuit breaker to initialize and reset when the power is abnormal; for example, when it is detected that the circuit breaker is not closed in place, the circuit breaker can be driven to close in place.

[0042] Therefore, in the circuit breaker provided by the embodiment of the present application, the electric transmission mechanism 11, the handle 14 and the operating mechanism 16 in the housing 10 are sequentially linked, and the handle 14 is driven by the electric transmission mechanism 11 to activate the operating mechanism 16 to realize automatic opening and closing; and the electric transmission mechanism 11 is also provided with a first micro switch 12, and / or the handle 14 is provided with a second micro switch 13, the first micro switch 12 and / or the second micro switch 13 are used to detect and control the action state of the electric transmission mechanism 11 and the handle 14, respectively, and feedback to the control unit, the control unit confirms the state of the circuit breaker according to the electrical signal of the first micro switch 12 and / or the second micro switch 13, and / or initializes and resets the circuit breaker when the power-on is abnormal. The present application can accurately detect the state of the circuit breaker through the setting of the first micro switch 12 and / or the second micro switch 13, improve the safety and reliability of the circuit breaker; and / or, initialize and reset the connection state of the circuit breaker when the power-on is abnormal, prevent the control circuit from misoperation, and help improve the reliability of the circuit breaker and the control circuit.

[0043] Specifically, Figure 3 As shown, the electric transmission mechanism 11 at least includes a sector gear 110 , and the handle 14 is provided with a handle gear 14 a , and the electric transmission mechanism 11 is linked to the handle 14 through the meshing of the sector gear 110 and the handle gear 14 a .

[0044] The electric transmission mechanism 11 meshes with the handle gear 14a on the handle 14 through the sector gear 110, so that the electric transmission mechanism 11 drives the handle 14 to move; the handle 14 is connected to the operating mechanism 16 through a connecting rod, and then drives the operating mechanism 16 to realize opening and closing.

[0045] The electric transmission mechanism 11 includes at least one of the following:

[0046] At least one sector gear 110, the handle 14 is provided with a handle gear 14a meshing with the sector gear 110, so that the transmission mechanism 11 and the handle 14 are linked;

[0047] At least one gear, at least one sector gear 110 meshes with at least one gear.

[0048] In one embodiment, there are at least two gears, the two gears mesh with each other, and the sector gear 110 meshes with an adjacent gear.

[0049] The electric transmission mechanism 11 forms a gear set, which includes a plurality of gears meshing in sequence. The first gear in the gear set is used to connect to the driving device, and the last gear in the gear set is used to mesh with the fan gear 110. In this way, the driving device sequentially drives the multiple gears to mesh and transmit, and then transmits through the fan gear 110 and the handle gear 14a, finally realizing the action of the operating mechanism 16.

[0050] Further, the circuit breaker includes at least one of the following:

[0051] The sector gear 110 is provided with a first boss 110a that cooperates with the first micro switch 12 to detect the meshing state between the sector gear 110 and the handle gear 14a;

[0052] The handle gear 14a is provided with a second boss 14a1 which cooperates with the second micro switch 13 to detect the opening and closing state of the circuit breaker.

[0053] The circuit breaker includes at least one of the following:

[0054] The first micro switch 12 abuts against the first boss 110a to trigger the first micro switch 12 to be turned on, and the meshing state of the sector gear 110 and the handle gear 14a is detected by the on-off state of the first micro switch 12;

[0055] The second boss 14a1 abuts against the second micro switch 13 to trigger the second micro switch 13 to be turned on, and the on / off state of the second micro switch 13 is used to detect the opening and closing state of the circuit breaker.

[0056] like Figure 4 As shown, when the electric transmission mechanism 11 and the first micro switch 12 cooperate, a first boss 110a is provided on the sector gear 110, and the first boss 110a abuts against the first micro switch 12 to trigger the connection of the first micro switch 12, and the on-off state of the first micro switch 12 is used to detect the meshing state of the sector gear 110 and the handle gear 14a.

[0057] A first boss 110a is formed on the sector gear 110, and the first boss 110a is used to trigger the connection of the first micro switch 12. When the first boss 110a abuts against the first micro switch 12, the first micro switch 12 is connected, and when the first boss 110a disengages from the first micro switch 12, the first micro switch 12 is disconnected; when the handle gear 14a and the sector gear 110 are just engaged, the first boss 110a triggers the first micro switch 12 to close and connect the first micro switch 12; when the first micro switch 12 is always in a closed state, it indicates that the handle gear 14a and the sector gear 110 are in a meshing state, and when the first micro switch 12 is in a disconnected state, it indicates that the handle gear 14a and the sector gear 110 are in a separated state.

[0058] Likewise, if Figure 5As shown, a second boss 14a1 is provided on the handle gear 14a, and the second boss 14a1 abuts against the second micro switch 13 to trigger the connection of the second micro switch 13, and the on-off state of the second micro switch 13 is used to detect the opening and closing state of the circuit breaker.

[0059] The second boss 14a1 formed on the handle gear 14a is used to trigger the connection of the second microswitch 13. When the second boss 14a1 abuts against the second microswitch 13, the second microswitch 13 is connected, and when the second boss 14a1 is disengaged from the second microswitch 13, the second microswitch 13 is disconnected; when the operating mechanism 16 is closed, the second boss 14a1 triggers the second microswitch 13, so that the second microswitch 13 is closed and connected, and the circuit breaker is in the closed state; when the second microswitch 13 is in the disconnected state, the circuit breaker is in the open state.

[0060] The detection status of the circuit breaker generally includes a normal state, a power-on abnormal state and a fault state; when the circuit breaker is in a normal state, when the first microswitch 12 is disconnected and / or the second microswitch 13 is disconnected, the circuit breaker is in a normal opening state, and an electric closing or manual closing command can be executed; when the first microswitch 12 is disconnected and / or the second microswitch 13 is closed, the circuit breaker is in a normal closing state, and an electric opening or manual opening command can be executed.

[0061] When the circuit breaker is in an abnormal power-on state, when the first microswitch 12 is closed and / or the second microswitch 13 is disconnected, it indicates that the circuit breaker is in an incomplete closing state. At this time, the control unit sends a command to the drive device to continue to execute the automatic closing command, and the automatic transmission mechanism 11, the handle 14 and the operating mechanism 16 are linked in sequence to drive the circuit breaker to continue closing, so that the connection state of the circuit breaker is initialized and reset.

[0062] When the first microswitch 12 is closed and / or the second microswitch 13 is closed, the circuit breaker is in a closed state, and the control unit sends a command to the drive device to continue to execute the automatic closing command. At this time, the first microswitch 12 is driven to open, so that the handle gear 14a and the fan gear 110 are separated and the circuit breaker is initialized and reset.

[0063] It should be noted that when the second micro switch 13 is closed, it indicates that the circuit breaker is in the closed state. When the circuit breaker is closed, the handle gear 14a and the fan gear 110 need to be separated so that the circuit breaker can be opened or other actions can be controlled by the handle 14. If the handle gear 14a and the fan gear 110 are always engaged, the handle 14 cannot be controlled. Therefore, once the second micro switch 13 is closed and the circuit breaker is closed, the first micro switch 12 needs to be disconnected to separate the handle gear 14a and the fan gear 110.

[0064] It should also be emphasized that the first micro switch 12 is disconnected only after the second micro switch 13 is closed, so as to ensure that the circuit breaker is fully closed and the handle gear 14 a is separated from the sector gear 110 .

[0065] When the circuit breaker is in a fault state, during the automatic closing process, the first micro switch 12 and / or the second micro switch 13 are opened-closed-opened respectively, which indicates that the circuit breaker is faulty, and a fault alarm is issued, and the circuit breaker closing failure is displayed.

[0066] When the circuit breaker fails, an alarm can be connected to the control unit, and the alarm is used to give a fault alarm; there are many specific alarm modes, such as sound alarm or red flashing, etc., which are not limited.

[0067] On the other hand, an operating button 15 is also provided on the housing 10 , and the operating button 15 is connected to the handle 14 via a connecting rod. The operating button 15 can drive the handle 14 to rotate, thereby driving the operating mechanism 16 to realize manual opening and closing.

[0068] The embodiment of the present application also provides an electrical equipment, which is equipped with the aforementioned circuit breaker, and the electrical equipment can be equipped with at least one of the following: distribution box, cable, distribution cabinet, motor, switch socket, lamp, air conditioner, electric water heater, electric meter, camera, telephone, computer, etc. Such electrical equipment can use the circuit breaker related structure of the present application to realize intelligent management, but it is not limited to the above intelligently managed electrical equipment, and can also be used in non-intelligent electrical equipment in traditional industries.

[0069] The embodiment of the present application also provides an electrical equipment, and the aforementioned circuit breaker is applied to the electrical equipment. The electrical equipment can be used for whole-house intelligence, applied to smart home and Internet of Things industries, to realize whole-house intelligent management.

[0070] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
