The cleaning frame 22 includes a frame body 221, which is made of stainless steel to reduce the corrosion of the circuit breaker by salt. The frame body 221 is located on the outer surface of the inner shell 1. Two rectangular through holes are opened on the back of the frame body 221. A push scraper 222 is connected to the front of the frame body 221. A rubber block is fixedly connected to the outer surface of the push scraper 222. The surface of the push scraper 222 is slidably connected to the inside of the circular tube on the front of the anti-corrosion shell 21.

The elastic metal strip 23 is made of stainless steel and is located at the bottom of the frame body 221. A rectangular through hole is opened on the front of the elastic metal strip 23.

[0023] The inner shell 1 is fixedly connected to the first terminal 3. The first terminal 3 is located on the front of the actuating mechanism 4.

At the same time, the top of the vertical rod 411 is connected to the rectangular through hole on the back of the anti-corrosion shell 21 and the frame 221. The vertical rod 411 is rotatably connected to the front of the sliding hole, and the horizontal rotating rod 412 is rotatably connected to the bottom of the inner wall of the inner shell 1 through a plastic column. The back of the inner wall of the inner shell 1 is fixedly connected to the electromagnetic push rod 413. The electromagnetic push rod 413 is electrically connected to the circuit module 8 through a wire. The electromagnetic push rod 413 is located on the back of the horizontal rotating rod 412. The back of the inner wall of the inner shell 1 is snapped with an elastic hook plate 414. The elastic hook plate 414 is made of stainless steel and is located on the right side of the electromagnetic push rod 413.

[0025] An electromagnetic actuation mechanism 42 is rotatably connected to the right side of the state lever 41, used to connect and disconnect the circuit breaker, thereby controlling the circuit's on / off state. The electromagnetic actuation mechanism 42 includes an actuation plate 421, which is slidably connected via a groove at the bottom of the inner wall of the inner shell 1. The top of the actuation plate 421 is fixedly connected to the back of the inner wall of the inner shell 1 via a spring. An L-shaped bend plate 422, made of copper, is fixedly connected to the right side of the actuation plate 421. A copper pad is fixedly connected to the back of the L-shaped bend plate 422. A coil winding 424 is fixedly connected to the bottom of the inner wall of the inner shell 1. The part is fixedly connected to the right side of the first terminal 3 via a copper strip. The front of the L-shaped bend plate 422 is electrically connected to the bottom of the coil winding 424 via a wire. An iron core rod 423 is slidably connected inside the coil winding 424 to receive the electromagnetic force generated when the coil winding 424 is energized and move. The iron core rod 423 includes an iron core. The back of the iron core is fixedly connected to the inside of the coil winding 424 via a spring. The back of the iron core rod 423 is fixedly connected to the bottom of the action plate 421 via a rubber head. The front of the iron core rod 423 is slidably connected to the back of the linkage rod 43. The surface of the linkage rod 43 is slidably connected to the bottom of the inner wall of the inner shell 1 via a plastic plate.

[0026] Linkage rod 43 is slidably connected to the front of electromagnetic actuation mechanism 42 and is used to realize the cooperation between actuation mechanism 4 and sealing shell 2 to clean the salt deposited inside sealing shell 2. Linkage rod 43 is fixedly connected to plastic plate by spring. The surface of linkage rod 43 is slidably connected to the circular through hole on the front of inner shell 1. The front of linkage rod 43 is located on the back of frame 221.

[0027] In use, the circuit breaker is erected and installed in the corresponding position inside the electrical equipment, with the vertical rod 411 at the top. Both ends of the line are then connected to the circuit breaker. The vertical rod 411 is pressed downwards, pushing one end of the horizontal rotating rod 412 downwards. The other end of the horizontal rotating rod 412 rises, causing the actuating plate 421 to slide upwards. As the actuating plate 421 slides, the top of the actuating plate 421 compresses the spring, causing the actuating plate 421 to slide upwards. The iron core rod 423 compresses the spring connected to the coil winding 424, and the bottom of the iron core rod 423 engages with the linkage. The top of rod 43 slides relative to each other, and at the same time, L-shaped bend plate 422 slides upward together with action plate 421. When action plate 421 reaches the top, the left side of action plate 421 presses against elastic hook plate 414, and elastic hook plate 414 undergoes elastic deformation. As action plate 421 moves upward, the left side of action plate 421 finally engages with the right side of elastic hook plate 414. At the same time, the copper pad at the top of L-shaped bend plate 422 fits against the bottom of right angle bend plate of interface 51, completing the circuit connection. When the circuit breaker is working, sealing shell 2 isolates inner shell 1 from external salt spray, preventing salt spray from directly contacting the outer surface of inner shell 1.

[0028] When a short circuit occurs in the circuit, the current through the coil winding 424 increases, and the electromagnetic force generated by the coil winding 424 increases. The iron core rod 423 moves downward under the electromagnetic force of the coil winding 424 and the elastic force of the spring. The iron core rod 423 drives the action plate 421 to move downward. The action plate 421 presses down on the elastic hook plate 414, causing the elastic hook plate 414 to deform elastically and eventually disengage from the elastic hook plate 414. The action plate 421 drives the L-shaped bend plate 422 to slide downward, eventually allowing the L-shaped bend plate 422 to disengage from the right-angle bend plate of the interface 51. At the same time, the action plate 421 drives the other end of the horizontal rotating rod 412 to rotate downward. The end of the horizontal rotating rod 412 connected to the vertical rod 411 moves upward, and the vertical rod 411 slides upward.

[0029] When the bottom of the iron core rod 423 moves downward, the bottom of the iron core rod 423 pushes the linkage rod 43 to slide downward, and the bottom of the linkage rod 43 pushes the frame 221 to slide downward. At the same time, the bottom of the frame 221 squeezes the elastic metal strip 23. The bottom of the frame 221 slides downward, and the top of its inner surface collides with the top of the inner shell 1. Since the frame 221 is made of stainless steel and has a certain elasticity, it will generate a certain vibration during the impact, thereby loosening the deposited salt. At the same time, the pusher scraper 222 interacts downward, and the metal block on the surface of the pusher scraper 222 scrapes away the deposited salt inside the circular tube of the anti-corrosion shell 21. When the circuit breaker is restored, the iron core rod 423 slides upward, releasing the push on the linkage rod 43. The linkage rod 43 resets under the action of the spring force, releasing the push on the cleaning frame 22 and the elastic metal strip 23. The cleaning frame 22 resets under the action of the elastic metal strip 23.

[0030] Please refer to Figures 1-8 for Embodiment 2. Based on Embodiment 1, the present invention provides a technical solution: A second terminal 5 is fixedly connected inside the inner shell 1. The second terminal 5 includes an interface 51. A circular blind hole is opened at the bottom of the interface 51. The circular blind hole of the interface 51 communicates with the circular through hole on the front of the inner shell 1. A right-angle bend plate is fixedly connected to the right side of the interface 51. An electromagnetic actuation mechanism 42 is located on the left side of the right-angle bend plate. Sealing strips 52 are fixedly connected to the bottom and top of the right-angle bend plate of the interface 51. The left and right sides of the interface 51 are fixedly connected to the bottom of the inner wall of the inner shell 1 through plastic plates. An arc-inducing plate 53 is fixedly connected to the left side of the interface 51. The back of the arc-inducing plate 53 is fixedly connected to the bottom of the inner shell 1 through plastic plates.

[0031] An arc-extinguishing chamber 6 is fixedly connected inside the inner shell 1. The arc-extinguishing chamber 6 is a metal grid-type magnetic blowout arc-extinguishing chamber. The arc-extinguishing chamber 6 is existing technology. The arc-extinguishing chamber 6 is fixedly connected to the left side of the arc-initiating plate 53. The arc-extinguishing chamber 6 is located on the right side of the linkage rod 43 and on the front of the electromagnetic action mechanism 42. It is used to absorb the electric arc generated during the circuit breaking process.

[0032] A honeycomb moisture-absorbing block 7 is fixedly connected inside the inner shell 1. The honeycomb moisture-absorbing block 7 is located on the back of the interface 51, on the right side of the arc-guiding plate 53, and on the left side of the right-angle bend plate of the interface 51. A hexagonal through hole is opened on the top of the honeycomb moisture-absorbing block 7. The honeycomb moisture-absorbing block 7 is made of moisture-absorbing material.

[0033] In use, in Embodiment 1, the two ends of the wires are connected to the circular blind holes at the bottom of the first terminal 3 and the bottom of the second terminal 5, respectively. The current flows from the first terminal 3 to the coil winding 424, from the coil winding 424 through the wires to the L-shaped bend plate 422, from the L-shaped bend plate 422 to the right-angle bend plate of the interface 51, and finally flows out through the interface 51. During the short-circuit breaking process in Embodiment 1, an arc is generated during the process of the L-shaped bend plate 422 separating from the right-angle bend plate of the interface 51. The arc is transmitted to the arc extinguishing chamber 6 through the L-shaped bend plate 422 and the arc-initiating plate 53. The arc is divided inside the arc extinguishing chamber 6 to finally complete the arc extinguishing. If an overload occurs, the left end of the right-angle bend plate of the interface 51 gradually heats up under the load and undergoes downward bending deformation. After bending deformation, it pushes the L-shaped bend plate 422 to move downward, and finally executes the process of the L-shaped bend plate 422 separating from the right-angle bend plate of the interface 51 in Embodiment 1.

[0034] If salt spray enters the inner shell 1, the moisture in the salt spray is absorbed by the honeycomb moisture-absorbing block 7 to prevent the moisture in the salt spray from interfering with the circuit breaker's connection process.

[0035] Please refer to Figures 1-10 for Embodiment 3. Based on Embodiments 1 and 2, the present invention provides a technical solution: A circuit module 8 is fixedly connected inside the inner shell 1. The circuit module 8 includes a closed shell 81, which is fixedly connected to the bottom of the inner wall of the inner shell 1. The closed shell 81 is located on the back of the first terminal 3 and on the front of the status bar 41. A rectangular through hole is opened at the top of the closed shell 81. A circuit board assembly 82 is fixedly connected inside the closed shell 81. The circuit board assembly 82 includes a circuit board and a microcontroller. The circuit board assembly 82 is electrically connected to the electromagnetic actuation mechanism 42. A humidity sensor 83 is fixedly connected to the top of the circuit board assembly 82. The humidity sensor 83 is electrically connected to the circuit board assembly 82.

A blade wheel is fixedly connected to the left side of the hollow cup motor. The active blowing mechanism 9 is fixedly connected to the back of the inner shell 1 from the front. The active blowing mechanism 9 is electrically connected to the circuit board assembly 82 through wires.

[0037] During use, the humidity sensor 83 detects the humidity inside the inner shell 1 in real time during the circuit breaker connection process. When the humidity data detected by the humidity sensor 83 exceeds the safe range, the microcontroller of the circuit board assembly 82 controls the elastic hook plate 414 to start. After the elastic hook plate 414 is started, it pushes the horizontal rotating rod 412 downward to one end of the action plate 421, and finally executes the circuit breaking process in Embodiment 1 to prevent the circuit breaker from working in a humidity environment outside the safe range and causing safety hazards.

[0038] During the circuit breaker connection process, the circuit board assembly 82 controls the hollow cup motor of the active blowing mechanism 9 to start. The hollow cup motor drives the impeller to rotate, and the rotation of the impeller generates airflow. The airflow pushes the gas in the gap between the inner shell 1 and the anti-corrosion shell 21 to prevent the deposition of salt in the salt spray.
