[0002] When cleaning large parts inside the enclosure, it is necessary to prevent the cleaning fluid from leaking out. Therefore, a sealing door needs to be installed at the entrance and exit of the enclosure. Currently, the traditional sealing door method is to hinge one side of the sealing door to the enclosure, allowing the sealing door to rotate. Then, a fixing mechanism is set on the movable side of the sealing door, such as hinged multiple bolts at the opening of the enclosure. The bolts are threaded to a handwheel, and the sealing door is equipped with a corresponding slot for the bolts. When sealing, the bolts enter the slots, and then the handwheel can be turned to press the sealing door tight.

[0003] The disadvantage is that in order to ensure the sealing effect, a large number of bolts are required, and the handwheel needs to be turned manually when opening and closing, which is inefficient. Utility Model Content

[0021] Reference Figures 1 to 3 The present invention will be further described below.

[0022] A sealing door of a cleaning device is provided, wherein a pressing mechanism is provided between the sealing door 1 and the cleaning chamber 2, the pressing mechanism including a pressing bracket 3, the pressing bracket 3 being slidably connected to the cleaning chamber 2, the sealing door 1 being located on the pressing bracket 3, a connecting rod 4 being provided between the pressing bracket 3 and the sealing door 1, the two ends of the connecting rod 4 being hinged to the pressing bracket 3 and the sealing door 1 respectively, and the hinge axis between the connecting rod 4 and the sealing door 1 being located below the hinge axis between the connecting rod 4 and the pressing bracket 3, the sealing door 1 being provided with a guide wheel 5, the cleaning chamber 2 being provided with a fixed support plate 6 corresponding to the guide wheel 5, the fixed support plate 6 being located below the opening of the cleaning chamber 2, and a driving mechanism being connected to the pressing bracket 3.

[0023] like Figures 1 to 3 As shown, when the sealing door 1 opens the opening of the cleaning chamber 2, the clamping bracket 3 is positioned above the opening under the drive mechanism. When sealing is required, the clamping bracket 3 is lowered. When the guide wheel 5 on the sealing door 1 contacts the fixed support plate 6 on the cleaning chamber 2 below, the sealing door 1 is exactly aligned with the opening of the cleaning chamber 2. The drive mechanism continues to press down the clamping bracket 3, which causes the sealing door 1 to move laterally toward the opening through the linkage of the connecting rod 4 until the sealing door 1 seals the opening. When opening is required, the rise of the clamping bracket 3 will first cause the sealing door 1 to move laterally to open the opening, and then be driven upward until the opening is fully opened. The sealing door 1 naturally hangs down under gravity, causing the connecting rod 4 to return to its tilted state, thus realizing the automatic opening and closing of the sealing door 1 with high efficiency.

[0024] like Figure 1 As shown, specifically, four connecting rods 4 are provided between the sealing door 1 and the pressing bracket 3.

The sliding plate 9 is slidably connected to the guide rail groove 8, thereby realizing the sliding guidance of the clamping bracket 3.

[0026] like Figure 1 As shown in this example, preferably, limit sensors 20 are provided at both ends of the guide rail 7 to limit the maximum movement distance of the clamping bracket 3.

[0027] Specifically, when the guide wheel 5 on the sealing door 1 contacts the fixed support plate 6, the clamping bracket 3 approaches the lower limit sensor 20. When the lower limit sensor 20 senses the clamping bracket 3, the sealing door 1 has completed the lateral movement and completely sealed the opening.

[0028] Specifically, the limit sensor 20 can be a proximity switch.

[0029] like Figure 2 As shown in this example, preferably, the sealing door 1 is provided with a limit block 10, and the pressing bracket 3 is provided with a limit screw 11 corresponding to the limit block 10. When the sealing door 1 starts, the limit block 10 will move toward the limit screw 11 until the limit block 10 contacts the limit screw 11. The lateral movement distance of the sealing door 1 can be limited by the limit block 10 and the limit screw 11.

[0030] Specifically, the limit screw 11 is threadedly connected to the clamping bracket 3 to achieve limit adjustment.

[0031] like Figure 2 As shown in this example, preferably, the sealing door 1 is provided with reinforcing ribs 19.

[0032] like Figure 2 As shown in this example, preferably, the cleaning tank 2 is provided with a water receiving tank 12 located below the opening. When the sealing door 1 moves laterally to open the opening, the cleaning liquid on the sealing door 1 will drip down into the water receiving tank 12, preventing the cleaning liquid from dripping onto the ground.

[0033] like Figure 3 As shown in this example, preferably, the sealing door 1 is provided with a sealing strip 13 corresponding to the opening of the cleaning box 2 on the side facing the cleaning box 2, so as to improve the sealing effect.
