[0014] The control method of the electrical control switch cabinet with protection function as described above comprises the following steps:

[0015] S1: After the drawer is pulled out from the drawer chamber, the slider can be pushed to move along the guide rod under the action of the first spring, and at the same time, the rack can be driven to move. When the rack moves, the gear and the rotating shaft can be pushed to rotate clockwise, thereby driving the rotating plate to rotate clockwise and rotate to a vertical state, so that the rubber strip can abut against the bottom of the drawer chamber, thereby sealing and protecting the drawer chamber, preventing external dust and other impurities from entering the drawer chamber, and preventing others from accidentally touching it, making it safer and more reliable, and ensuring its use effect and life;

[0016] S2: When the drawer is inserted into the drawer chamber, the rotating plate can be pushed to rotate counterclockwise along the rotating shaft, and after rotating to a horizontal state, it is in the avoidance groove to avoid interference. At the same time, when the rotating shaft rotates counterclockwise, it can drive the gear to rotate synchronously. When the gear rotates, it can push the rack to move, and the first spring is compressed;

[0017] S3: When the drawer is inserted into the drawer chamber, when the drawer abuts against the side wall of the rotating plate, the rotating plate can be pushed to rotate upward along the rotating shaft. When the drawer abuts against the brush, the third spring is stretched. When the rotating plate rotates upward, the third push rod is driven to rotate synchronously. When the third push rod is aligned with the conical groove, the movable plate is pushed to move under the action of the fourth spring, and the third push rod is inserted into the conical groove. When the third push rod slides from the conical groove, the movable plate can be pushed to move. At the same time, the fourth spring is compressed. This reciprocating process can make the movable plate and the brush reciprocate. Moreover, under the action of the third spring, the brush can abut against the side walls of the drawer and the plug, so that the surface of the plug can be automatically cleaned, thereby ensuring the reliability of the connection, making the protection effect better, and ensuring the effect and life of its use.

[0018] S4: When the rack moves, it drives the connecting plate to move, and at the same time, it can drive the second push rod to slide in the second sliding groove, thereby pushing the rotating block to rotate clockwise along the rotating pin, and then making the first push rod slide in the first sliding groove. At this time, the movable cover can be pushed to move along the guide rail and move to just above the strip opening. Under the action of the second spring, the movable frame can be pushed downward, and the drying box can be driven to move into the drawer chamber. When the drawer is against the inclined surface, the movable frame and the drying box can be pushed upward. At the same time, the second spring is compressed. After the drawer is inserted into place, under the action of the second spring, the movable frame and the drying box can be moved downward again and moved into the drawer, so that the drawer chamber and the drawer can be dried to avoid the influence of humid air, so as to achieve better protection effect and ensure its use effect and life.

[0019] S5: When the drawer is pulled out, the movable cover can be moved and reset through the first pushing mechanism and the second pushing mechanism, and moved to the top of the drawer chamber. At the same time, when the inclined surface abuts against the side wall of the strip opening, the movable frame and the drying box can be pushed upward into the movable cover, and the second spring is compressed, so that the movable cover can be sealed to avoid waste of desiccant and make higher utilization of the desiccant.

When the rack (203) moves, the gear (204) and the rotating shaft (202) can be pushed to rotate clockwise, thereby driving the rotating plate (12) to rotate clockwise and rotate to a vertical state, so that the rubber strip (13) can be abutted against the bottom of the drawer chamber (101), thereby sealing and protecting the drawer chamber (101), preventing external dust from entering the drawer chamber (101), and preventing others from accidentally touching the drawer chamber (101); S2: When the drawer (102) is inserted into the drawer chamber (101), the rotating plate (12) can be pushed to rotate counterclockwise along the rotating shaft (202), and after rotating to a horizontal state, it is located in the avoidance groove (10) to avoid interference. At the same time, when the rotating shaft (202) rotates counterclockwise, it can drive the gear (204) to rotate synchronously. When the gear (204) rotates, it can push the rack (203) to move, and the first spring (404) is compressed; S3: When the drawer (102) is inserted into the drawer chamber (101), when the drawer (102) abuts against the side wall of the rotating plate (12), the rotating plate (12) can be pushed to rotate upward along the rotating shaft (202). When the drawer (102) abuts against the brush (16), the third spring (503) is stretched. When the rotating plate (12) rotates upward, the third push rod (601) is driven to rotate synchronously. When the third push rod (601) is aligned with the conical groove (602), the fourth spring (703) pushes the movable plate (15) to rotate upward. The third push rod (601) is moved and the third push rod (601) is inserted into the conical groove (602). When the third push rod (601) slides from the conical groove (602), it can push the movable plate (15) to move. At the same time, the fourth spring (703) is compressed. In this way, the movable plate (15) and the brush (16) can move back and forth. Moreover, under the action of the third spring (503), the brush (16) can abut against the side walls of the drawer (102) and the plug (103), so that the surface of the plug (103) can be automatically cleaned; S4: When the rack (203) moves, it drives the connecting plate (901) to move, and at the same time, it can drive the second push rod (903) to slide in the second slide groove (902), thereby pushing the rotating block (803) to rotate clockwise along the rotating pin (802), thereby making the first push rod (806) slide in the first slide groove (804). At this time, it can push the moving cover (19) to move along the guide rail (18) and move to the top of the strip opening (11). Under the action of the second spring (302), it can push the moving frame (20 ) moves downward and drives the drying box (21) to move into the drawer chamber (101); when the drawer (102) abuts against the inclined surface (2001), the movable frame (20) and the drying box (21) can be pushed to move upward; at the same time, the second spring (302) is compressed, and after the drawer (102) is inserted into place, under the action of the second spring (302), the movable frame (20) and the drying box (21) can move downward again and move into the drawer (102), so that the drawer chamber (101) and the drawer (102) can be dried; S5: When the drawer (102) is pulled out, the movable cover (19) can be moved and reset through the first pushing mechanism and the second pushing mechanism, and moved to the top of the drawer chamber (101). At the same time, when the inclined surface (2001) abuts against the side wall of the strip opening (11), the movable frame (20) and the drying box (21) can be pushed upward into the movable cover (19), and the second spring (302) is compressed, so that the movable cover (19) can be sealed.
