[0030] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0031] In the prior art, cleaning devices used to clean glass exterior walls or glass windows, such as window cleaning robots, are equipped with a cleaning cloth or brush at the bottom. By moving on the glass, they use the friction generated during movement and the cleaning agent to wipe away stains on the glass surface.

[0032] When the power cord is too long, it can drag the cleaning device, limiting its cleaning range. If the power cord is shorter than the distance from the socket to the glass to be cleaned, the glass cannot be effectively cleaned. Thus, the power cords in the existing technology are either too long or too short, causing inconvenience to the user.

[0033] Reference Figures 1 to 2 To solve the above-mentioned technical problems, this embodiment provides a cleaning device with an adjustable power cord length, including: a cleaning body 1, a power cord 2, an adjustment component 3, and a safety rope 5;

[0034] The cleaning unit 1 is connected to the power cord 2;

[0035] The adjustment component 3 can move along the length of the power cord 2 and be fixed at any position on the power cord 2;

[0036] The first end of the safety rope 5 is fixed to a fixed object, and the second end of the safety rope 5 is connected to the adjustment component 3.

[0037] In use, the first end of the safety rope is fixed to a fixed object such as a building, and the second end of the safety rope is connected to the adjustment component. Moving the adjustment component along the length of the power cord adjusts its position on the power cord, thereby controlling the length of the power cord between the cleaning body and the adjustment component. For example, when cleaning a floor-to-ceiling window, the cleaning body 1 requires a large range of movement. By moving the adjustment component 3, the distance between the cleaning body 1 and the adjustment component 3 is increased, thus ensuring that the length of the power cord 2 between the cleaning body 1 and the adjustment component 3 matches the movement distance of the cleaning body 1. Alternatively, when cleaning a small glass window, the distance between the cleaning body 1 and the adjustment component 3 is reduced to prevent the power cord 2 from being too long and dragging the cleaning body 1, causing the power cord 2 to become knotted or excessively pulling on the cleaning body 1, thus affecting the cleaning operation. The cleaning device in this embodiment can also adapt to glass surfaces of different sizes and shapes, greatly improving the user experience.

[0038] Therefore, in this embodiment, the length of the power cord 2 between the cleaning body 1 and the adjustment component 3 can be arbitrarily adjusted according to the cleaning range of the cleaning body 1, which can avoid the problem of increasing the extension of the power cord and the loosening of the power cord connector, and improve the convenience of the user in using the cleaning device.

[0039] In the above embodiment, if the second end of the safety rope 5 is rigidly connected to the adjustment component 3, the cleaning body 1 may bend at the edge where the power cord 2 connects to the adjustment component 3 during cleaning. Over time, this can cause the insulation layer of the power cord 2 to wear, crack, or even break after repeated bending, leading to a risk of leakage. Furthermore, it may cause the copper wires inside the power cord 2 to break or loosen, increasing resistance and reducing conductivity. This situation not only shortens the lifespan of the power cord but may also threaten the safety of the user, especially during high-altitude operations, where damage to the power cord could cause the cleaning device to lose control, leading to serious safety accidents.

[0040] To address the aforementioned issues, in one embodiment, the second end of the safety rope 5 is movably connected to the adjusting component 3. When the cleaning body 1 moves for cleaning, the adjusting component 3 rotates relative to the safety rope 5 under the influence of the cleaning body 1. This not only effectively reduces wear on the power cord but also maintains the power cord's natural state during movement, preventing damage due to excessive bending, reducing the risk of damage to the power cord 2, and extending the lifespan of the device.

[0041] In this embodiment, the plane where the first connecting ring 51 is located intersects the plane where the second connecting ring 33 is located. The second connecting ring 33 rotates around the contact point between the first connecting ring 51 and the second connecting ring 33. As the cleaning body 1 moves, the cleaning body 1 drives the power cord 2, the adjustment component 3 and the second connecting ring 33 to rotate.

[0042] Furthermore, the second end of the safety rope 5 is provided with a first connecting ring 51, and the adjusting component 3 is provided with a second connecting ring 33, wherein the first connecting ring 51 and the second connecting ring 33 are movably connected.

[0043] As an example, the first connecting ring 51 and the second connecting ring 33 can be circular, D-shaped or square. The shapes can be selected according to the actual use scenario, as long as the first connecting ring 51 and the second connecting ring 33 are movably connected.

[0044] Furthermore, the adjustment component 3 includes an elastic friction element 31 and a pressing component 32 disposed outside the power line 2;

[0045] The extrusion member 32 is sleeved on the outside of the elastic friction member 31. The extrusion member 32 is used to extrude the elastic friction member 31, causing the elastic friction member 31 to deform and increasing the contact area between the elastic friction member 31 and the power line 2, thereby increasing the friction between the elastic friction member 31 and the power line 2.

[0046] Similarly, when adjusting the position of the adjustment component 3, the squeezing member 32 is adjusted to relax the elastic friction member 31 and reduce the contact area between the elastic friction member 31 and the power line 2, thereby reducing the friction between the elastic friction member 31 and the power line 2. At this time, the squeezing member 32 can be pulled along the length of the power line 2.

[0047] Specifically, the elastic friction element 31 is configured as an elastic rubber plug.

[0048] Specifically, the extrusion member 32 includes a first extrusion member 321 and a second extrusion member 322, wherein the first extrusion member 321 and the second extrusion member 322 are threadedly connected.

[0049] Understandably, both the first extruder 321 and the second extruder 322 are provided with cavities to accommodate the elastic friction member 31. For example, when the second extruder 322 is turned clockwise, it rotates relative to the first extruder 321, causing the volume of the cavities of the first extruder 321 and the second extruder 322 to decrease. This compresses the elastic friction member 31 along the length of the power line 2, causing the elastic friction member 31 to deform and increasing the contact area between the elastic friction member 31 and the power line 2. At this time, the relative position of the power line 2 and the extruder 32 is fixed. Conversely, when the second extruder 322 is turned counterclockwise, the volume of the cavities of the first extruder 321 and the second extruder 322 increases, and the elastic friction member 31 is relieved. At this time, the position of the elastic friction member 31 can be moved.

[0050] In this embodiment, the first extrusion member 321 and the second extrusion member 322 are threaded together. The user can adjust the number of rotations of the second extrusion member 322 as needed, and gradually fine-tune the extrusion amount of the elastic friction member 31 to precisely control the fixed state of the power cord. This ensures that the power cord 2 will not loosen due to insufficient friction or be damaged due to excessive friction during use, thereby improving the stability and service life of the equipment.

[0051] In one embodiment, the second end of the safety rope 5 is provided with a first connecting ring 51, and the adjusting component 3 is provided with a second connecting ring 33. The first connecting ring 51 and the second connecting ring 33 are movably connected, and the second connecting ring 33 is fixedly mounted on the first pressing member 321 to ensure a stable connection between the safety rope 5 and the adjusting component 3, avoiding safety hazards caused by connection failure during high-altitude operations. When turning the second pressing member 322, the second connecting ring 33 can be used as a force point for the first connecting ring 51 to assist in turning, allowing the user to adjust the degree of compression of the elastic friction member 31 more easily and quickly.

[0052] More specifically, the first extruder 321 is provided with a first auxiliary twisting structure 3211 to reduce the slippage of the user's hand when twisting the first extruder 321 and to reduce the inability to twist the first extruder 321 relative to the second extruder 322 due to excessive friction between the first extruder 321 and the second extruder 322.

[0053] More specifically, the second extruder 322 is provided with a second auxiliary turning structure 3221. Similarly, the second auxiliary turning structure 3221 reduces the slippage of the user's hand relative to the second extruder 322 when turning the second extruder 322. Even under conditions of high friction, it can be adjusted smoothly, further improving the ease of use of the equipment.

[0054] Specifically, the first auxiliary twisting structure 3211 and the second auxiliary twisting structure 3221 are reinforcing ribs with concave and convex textures that protrude from the surfaces of the first connecting ring 51 and the second connecting ring 33. It can be understood that the reinforcing ribs protrude along the length direction of the power line 2 and are distributed along the periphery of the power line. The style of the reinforcing ribs is not limited. The reinforcing ribs serve as force-bearing structures to assist in twisting the second extrusion member 322.

[0055] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
