A supporting sheet 531 is rotatably provided at the bottom end of the threaded rod 53, and the rear side of the supporting sheet 531 is fixed to the cover seat 51 to play a supporting role and ensure the stability of the rotation of the threaded rod 53.

[0026] See also Figure 3 , Figure 4 and Figure 5 The utility model provides a multifunctional DCS control device, wherein the brushing structure 56 comprises a slider 561 fixed to the inner wall of the cover seat 51 on one side, a slider 562 slidably connected to the other side of the slider 561, and a cleaning head assembly 563 fixedly connected to the bottom end of the slider 562. The top side of the slider 562 is fixed to the cross frame 55, so that the slider 562 drives the cleaning head assembly 563 to shift longitudinally on the slider 561 under the action of the cross frame 55. The slider 561 and the slider 562 are both provided with two groups, and the two groups of sliders 561 and the slider 562 are respectively located on the left and right sides of the inside of the cover seat 51 to ensure stable longitudinal displacement of the slider 562.

[0027] The cleaning head assembly 563 includes a rectangular frame cover 5631 fixed to the top side of the slide 562, a driving motor 5632 fastened to the middle side of the rectangular frame cover 5631, a gear 5633 connected to the driving motor 5632 and not being an output end, a first rack 5634 meshed with the top side of the gear 5633, a second rack 5635 meshed with the bottom side of the gear 5633, a first brush piece 5636 fixedly connected to the rear side of the first rack 5634, and a second brush piece 5637 fixedly connected to the rear side of the second rack 5635, and a first brush piece 5636 fixedly connected to the rear side of the second rack 5635. The middle side of the gear 5633 is rotatably connected with the rectangular frame cover 5631 to ensure the stability of the rotation of the gear 5633. The rectangular frame cover 5631 is made of aluminum alloy, which is light and not easy to rust. The upper and lower sides of the rear part of the rectangular frame cover 5631 are respectively provided with a first slide groove 56311 and a second slide groove 56312, and the first brush piece 5636 and the second brush piece 5637 respectively penetrate the inner side of the first slide groove 56311 and the second slide groove 56312 and are laterally slidably connected thereto to ensure the stable lateral displacement of the first brush piece 5636 and the second brush piece 5637;

[0028] The first brush piece 5636 and the second brush piece 5637 are both provided with bristles on the rear side, and the rear side of the bristles contacts the door body 2 to facilitate cleaning of the display screen 3 and the control button 4. The first rack 5634 and the second rack 5635 have the same structure and size, and the first rack 5634 and the second rack 5635 are symmetrically located in the middle of the gear 5633 in the upper and lower directions, so that the first rack 5634 and the second rack 5635 are shifted in opposite directions on the upper and lower sides of the gear 5633, thereby driving the first brush piece 5636 and the second brush piece 5637 to shift and clean on the upper and lower sides respectively.

[0029] Here’s how it works:

[0030] First, fix the control body 1 at the position where it needs to be used, then connect the control body 1 to the external device, and display the control data information on the display screen 3 to use this design;

[0031] Secondly, after long-term use, the user can start the control servo motor 52 and the drive motor 5632. After the servo motor 52 is started, it drives the threaded rod 53 to rotate. The threaded rod 53 cooperates with the internal thread block 54 to make the cross frame 55 drive the slide 562 to shift longitudinally on the slide block 561, so that the slide 562 drives the rectangular frame cover 5631 to move downward. At the same time, after the drive motor 5632 is started, it reciprocates forward and reverse. Under the action of the drive motor 5632, the gear 5633 drives the first rack 5634 and the second rack 5634 to rotate. 635 meshing transmission, the first rack 5634 and the second rack 5635 are respectively symmetrically located at the middle of the gear 5633 in the opposite directions, so that the first rack 5634 and the second rack 5635 make opposite lateral displacements on the upper and lower sides of the gear 5633, respectively driving the first brush piece 5636 and the second brush piece 5637 to make lateral displacements on the upper and lower sides, and then the first brush piece 5636 and the second brush piece 5637 make lateral reciprocating displacements in the process of moving downward to clean the display screen 3 and the control button 4;

[0032] Once again, after cleaning the display screen 3 and the control button 4 , the servo motor 52 is reset, so that the rectangular frame cover 5631 is moved back to the inside of the cover seat 51 .

[0033] The utility model provides a multifunctional DCS control device. By optimizing the arrangement of a cleaning mechanism 5, a rectangular frame cover 5631 is stably displaced downward under the action of a servo motor 52. During the movement of the rectangular frame cover 5631, a driving motor 5632 is started at the same time. After the driving motor 5632 is started, it reciprocates in positive and negative directions. A first rack 5634 and a second rack 5635 are respectively symmetrically located at the middle of a gear 5633 in opposite directions up and down. Thus, the first rack 5634 and the second rack 5635 are transversely displaced in opposite directions at the upper and lower sides of the gear 5633. Under the action of the driving motor 5632, a first brush piece 5636 and a second brush piece 5637 are respectively driven to transversely displace at the upper and lower sides. Then, during the downward movement of the first brush piece 5636 and the second brush piece 5637, the first brush piece 5636 and the second brush piece 5637 are reciprocally displaced laterally to clean a display screen 3 and a control button 4. This prevents a large amount of dust from being attached to the display screen 3 and the control button 4 during long-term use, thereby affecting the viewing effect of the display screen. Furthermore, after operating the control button 4, it is not easy for the hand to be contaminated with dust. The utility model has relatively strong practicality.
