[0039] The filter plate 104c is provided to filter the protective cover 104b. When the circuit breaker 101 is used for a long time, heat will be generated. At this time, the filter plate 104c can allow air to circulate in the protective box 104a, thereby facilitating the heat dissipation of the circuit breaker 101. When the circuit breaker 101 is damaged and needs maintenance, the user can open the observation door 104d to facilitate the user to repair the circuit breaker 101.

[0040] Specifically, the cleaning part 201 includes a cleaning brush 201a, a threaded rod 201b and a baffle 201c.

There are two sliders 202b, which are fixed on both sides of the collection box 202a respectively. A slide groove is set in the protection box 104a, and the slider 202b slides in the slide groove. When it is necessary to collect dust, the collection box 202a is moved to the outside of the protection box 104a, and then the cleaned dust can fall into the collection box 202a. The setting of the slider 202b can support the collection box 202a when it moves to prevent the collection box 202a from shifting. After the collection box 202a collects the dust, the collection box 202a needs to be stored to prevent the collection box 202a from being exposed to the outside for a long time, causing other debris to enter the collection box 202a and affect the collection of dust by the collection box 202a.

[0046] Specifically, the collecting member 202 also includes a driving rod 202c, a driving block 202d and a supporting rod 202e.

When the driving rod 202c moves, it can drive one end of the driving block 202d to move on the support rod 202e. The support rod 202e supports the driving block 202d, so that the driving rod 202c can move smoothly and prevent the driving rod 202c from deviating during movement.

[0048] Example 3

[0049] Reference Figure 1 to Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0050] Specifically, the driving member 203 includes a rack 203a, a first gear 203b, a movable block 203c, a positioning bar 203d, a spring 203l and a fixed block 203e.

At this time, the movement of the movable block 203c can drive the rack 203a to move and re-engage with the first gear 203b, so that the rack 203a can drive the collection box 202a to move and store it. The positioning bar 203d is used to support the movable block 203c to prevent the movable block 203c from deviating. The fixed block 203e is fixed to one side of the rack 203a.

[0053] The rotation of the rotating rod 203f can drive the first gear 203b to rotate. A fixed sleeve is arranged on the outer side of the rotating rod 203f. The fixed sleeve is movably connected to the rotating rod 203f. The fixed sleeve is fixed to one side of the protective box 104a. The rotating rod 203f can be supported by the setting of the fixed sleeve to prevent the rotating rod 203f from shifting during rotation. The second gear 203g can drive the rotating rod 203f to rotate by rotating. The third gear 203h is rotatably connected to one side of the protective cover 104b through a bearing. The rotation of the third gear 203h can drive the second gear 203g to rotate.

[0054] Specifically, the driving member 203 further includes a first pulley 203i, a belt 203j and a second pulley 203k.

[0056] When in use, after the circuit breaker 101 has been used for a long time, a lot of dust will be collected on it. At this time, the dust needs to be cleaned. First, the motor 201d is started. The motor 201d drives the threaded rod 201b to rotate. The rotation of the threaded rod 201b can drive the cleaning brush 201a to move. The cleaning brush 201a moves on the top of the filter plate 104c to remove the dust on the filter plate 104c. When cleaning the filter plate 104c, the dust on it needs to be collected. Therefore, when the motor 201d rotates, the second pulley 203k can also be driven to rotate.

[0057] When the rack 203a moves one end of the first gear 203b, the teeth on the first gear 203b will contact the movable block 203c and then squeeze it to make the movable block 203c move. When the movable block 203c moves, it can apply a squeezing force to the spring 203l, and the movable block 203c can be returned to its original position by the rebound force of the spring 203l, so that the two can contact again, so that the first gear 203b can be idle, so that the threaded rod 201b can continue to rotate to comprehensively clean the filter plate 104c. When the cleaning brush 201a is moved to one side of the filter plate 104c, the baffle 201c can be used to block and guide the dust so that the dust can enter the collection box 202a. A collection frame is also provided in the collection box 202a for collecting dust. When the collection frame is full of dust, the collection frame can be taken out of the collection box 202a to clean the dust, and then the collection frame can be put back into the collection box 202a for next use.

[0058] After cleaning the surface of the filter plate 104c, the reversing motor 201d returns the cleaning brush 201a to its original position. When the cleaning brush 201a returns to its original position, the first gear 203b can be reversed. Then the first gear 203b contacts the inclined surface of the movable block 203c to move the movable block 203c. At this time, the movement of the movable block 203c can drive the rack 203a to move and re-engage with the first gear 203b, so that the rack 203a can drive the collection box 202a to move for storage.
