Description

Technical Field

[0001] This utility model relates to the field of roller shutter door equipment technology, specifically an automatic cleaning roller shutter door. Background Technology

[0002] Roller shutters are doors with multiple articulated door panels linked together. They rotate up and down around a central roller within fixed tracks. They serve multiple purposes and are commonly used in commercial shops, factory workshops, warehouses, and other places. On the one hand, they can isolate spaces and divide areas, such as separating the interior of a shop from the outside street. On the other hand, they can effectively block dust, rainwater, and sand from entering the interior, providing protection. They can also, to a certain extent, ensure the safety of the premises and prevent criminals from entering at will, thus playing a certain role in theft prevention.

[0003] For example, a Chinese patent document discloses an electric roller shutter door with an automatic cleaning function (publication number: CN221646814U). Although this patent has been approved, it controls the circulating air pump to start when the winding mechanism rolls up the curtain slats. Air is delivered through two first pipes into multiple nozzles, which blow dust from the grooves of the curtain slats, facilitating cleaning of the uneven slats. While cleaning the curtain slats with air, the air inside the waste bin is extracted, creating negative pressure. This draws dust from inside the two outer shells into the waste bin through a second three-way pipe, two second pipes, and two dust collection hoods. The dust is then blocked by a filter to prevent it from scattering. Blowing and suction are performed simultaneously, ensuring cleaning efficiency and saving energy. By starting two motors, two brushes are driven to rotate, and the two brushes perform deep cleaning on both the front and back sides of the curtain slats, improving cleaning efficiency and making the cleaning more thorough.

[0004] However, the cleaning process achieved through air blowing, vacuuming, and dual brushes presents a significant challenge due to its complex assembly and disassembly: the cleaning components rely on the cooperation of multiple parts such as motors, air pumps, pipes, and filters. During installation, it is necessary to align the brush shafts and connect the air pipes, which involves cumbersome steps and requires specialized tools. The filters need to be cleaned regularly, and the air pipes are prone to clogging due to dust or loosening due to vibration. Furthermore, the waste bin is fixed with bolts, requiring the power to be turned off and the machine to be disassembled during cleaning. The complex and time-consuming operation makes the overall disassembly inconvenient problem quite prominent. Utility Model Content

[0025] Reference Figures 1 to 3 The docking mechanism 4 includes a fixed fastener 401, a rotating fastener 402 and an active rotating shaft 403. The fixed fastener 401 is fixedly connected to the upper part of the front side of the door frame 1 by screws. The rotating fastener 402 is set on the front of the fixed fastener 401 by a hinge. The active rotating shaft 403 is fixedly connected to one end of the waterproof motor compartment 7.

[0026] The limiting insert 404, the docking insert 405, and the threaded fastener 406 are provided.
