[0002] With the continuous development of science and technology and the increasing sophistication of production processes, various equipment and systems in clean rooms need to be accurately remotely controlled and monitored. As the centralized processing unit of these control instructions and signals, the importance of the remote control box is self-evident.

[0003] When workers need to repair electrical components inside the control box, the door of a traditional control box often swings due to the lack of an effective fixing mechanism, which hinders the workers' operating space and vision, increasing the difficulty and time of repair.

[0004] At the same time, when the control box is in operation, the internal electrical components will generate heat. Good heat dissipation is essential for its stable operation. It is common to use fans to speed up the air flow rate to dissipate heat. However, since the clean room has certain requirements for air humidity, it is inevitable that the air contains a certain amount of moisture. During the heat dissipation process, the moisture in the clean room air will enter the control box. This moisture will gradually condense or adhere to the surface of the electrical components. Over time, it will have an adverse effect on the normal use of the electrical components, such as causing short circuits, damage, etc., reducing the reliability and service life of the control box, and thus affecting the normal operation of the entire clean room system.

The heat dissipation component includes a filter 51. The filter 51 can prevent impurities from entering the control box body 1. A fan 52 is arranged on the inner wall of the rear side of the control box body 1. The filter 51 and the fan 52 are arranged in two groups, which are evenly distributed on the upper surface and the lower surface of the control box body 1. The fan 52 is a prior art and can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The fan 52 located at the top is used to blow the air inside the control box body 1 upward, and the fan 52 located at the bottom is used to blow the external air into the inside from the bottom of the control box body 1. The two fans 52 can form an air duct to speed up the air flow rate and dissipate heat for the electrical components inside the control box body 1. A slide groove 502 is provided on the inner wall at the bottom end of the control box body 1, and the inner wall of the slide groove 502 is elastically connected to a positioning ring 54 through a connecting spring 55.

[0035] Reference Figure 2 - Figure 4 The heat dissipation component also includes a placement plate 53, which is located at the bottom end of the control box body 1. An indicator block 56 is fixedly connected to the left surface of the placement plate 53. The surface of the indicator block 56 is sprayed with a striking color. An observation groove 501 is provided on the left surface of the control box body 1. The indicator block 56 is located above the observation groove 501.

By pulling the pull ring 6 upward, the activated carbon plate 3 can be pulled out from the placement plate 53, which is convenient for replacing the activated carbon plate 3.

[0036] Reference Figure 1 , Figure 2, Figure 5 The positioning assembly also includes a card slot 401, and the inner wall of the rotating shaft 42 is elastically connected with a card block 44 through a compression spring 43. The upper surface of the card block 44 is set as an arc surface. When the arc surface of the card block 44 is squeezed, the card block 44 will move downward.

[0037] Reference Figure 2 - Figure 4 The rear surface of the sleeve 41 is fixedly connected to the right end of the front surface of the control box body 1. The front surface of the box door 2 is provided with a lock to facilitate locking the box door 2 and ensure that the box door 2 remains stable when closed. The filter 51 is installed on the lower surface of the control box body 1. The filter 51 is fixed by bolts and can be removed. The filter 51 is located below the fan 52.

[0038] Reference Figure 2 - Figure 4 The slide groove 502 is opened in a ring shape, and the positioning ring 54 is set in a ring shape. The two fit each other. The positioning ring 54 is slidably connected to the inner wall of the slide groove 502 and slides longitudinally. The upper surface of the positioning ring 54 protrudes from the upper surface of the slide groove 502. One end of the connecting spring 55 is fixedly connected to the inner wall of the bottom end of the slide groove 502, and the other end of the connecting spring 55 is fixedly connected to the upper surface of the positioning ring 54. When the positioning ring 54 moves downward, it will squeeze the connecting spring 55 to generate a reaction force. In the initial state, the weight of the positioning ring 54, the activated carbon plate 3 and the placement plate 53 is not enough to compress the connecting spring 55. When the activated carbon plate 3 absorbs a certain amount of water, the weight will increase, the connecting spring 55 will be compressed, and the placement plate 53, the positioning ring 54 and the indicator block 56 will move downward.

[0039] Reference Figure 2 - Figure 4 The lower surface of the placement plate 53 is fixedly connected to the upper surface of the positioning ring 54, and the placement plate 53 is slidably connected to the inner wall of the control box body 1 to slide longitudinally.

[0040] Reference Figure 1 , Figure 2 , Figure 5 The card slot 401 is opened at the left end of the upper surface of the sleeve 41. When the box door 2 is closed, the card block 44 will retract into the rotating shaft 42, and the compression spring 43 is in a compressed state. The card block 44 is inserted into the inner wall of the card slot 401. After the box door 2 is rotated 180° to open, the card block 44 will be aligned with the card slot 401. The card block 44 inserted into the card slot 401 will limit the rotating shaft 42. The card block 44 passes through and is slidably connected to the upper surface of the rotating shaft 42, sliding longitudinally. Pressing the card block 44 downward can align its arc surface with the sleeve 41. At this time, rotating the box door 2 drives the rotating shaft 42 to rotate, and the arc surface of the card block 44 will be squeezed.

[0041] Reference Figure 1 , Figure 2 , Figure 5One end of the compression spring 43 is fixedly connected to the lower surface of the block 44 , and the other end of the compression spring 43 is fixedly connected to the inner wall of the bottom end of the rotating shaft 42 . The downward movement of the block 44 will squeeze the compression spring 43 .

[0042] Working principle: The control box body 1 is used to control the electrical equipment and systems in the clean room. After the fan 52 is started, it will accelerate the air circulation and can dissipate heat for the internal electrical components. The upper and lower sets of filters 51 can block impurities in the air, and the external air will first contact the activated carbon board 3 before contacting the internal electrical components of the control box body 1. The moisture in the air will be absorbed, and the weight of the activated carbon board 3 will gradually increase. When the weight of the activated carbon board 3 absorbed by moisture increases to be greater than the elasticity of the connecting spring 55, the connecting spring 55 will be compressed to move the placement plate 53, the positioning ring 54 and the indicator block 56 downward. By observing the position of the indicator block 56 through the observation groove 501, it can be determined whether the activated carbon board 3 needs to be replaced. When replacing, open the box door 2 and then pull up the ring 6 to pull out the activated carbon board 3, and insert the new activated carbon board 3 into the placement plate 53.

[0043] When inspecting the electrical components inside the control box body 1, first open the box door 2 and rotate it 180° when opening. The block 44 will be aligned with the slot 401, and the block 44 will be plugged into the slot 401 to limit the box door 2, thereby providing the staff with sufficient operating space and a clear line of sight, significantly reducing the difficulty of maintenance and saving maintenance time. After the inspection is completed, press the block 44 downward to align its arc surface with the sleeve 41, and then rotate the box door 2 in the opposite direction to close it. The reverse rotation of the box door 2 will drive the shaft 42 to rotate synchronously, the arc surface of the block 44 will be squeezed, and the block 44 will move downward and retract into the shaft 42 to contact the limit. After the box door 2 is closed, the box door 2 is locked.
