Description

Technical Field

[0001] This utility model relates to the field of cleaning, and in particular to a cleaning device with an integrated scraper. Background Technology

[0002] In the prior art, in order to continuously clean and remove hair and dirt from the roller brush, many cleaning devices are equipped with roller brush scrapers or scrapers. However, due to technical reasons, scrapers or scrapers can only be made in a split design. The split design is not securely installed and may loosen or become unstable after long-term use.

[0003] Furthermore, most roller brushes on the market use a single-roller design, which inevitably leads to incomplete cleaning or the residue of sewage and stains. Only a few manufacturers use a dual-roller design, but its design is very simple, merely layering together. Long-term use can result in quality issues. Additionally, due to technical limitations, the cleaning layer and track are integrated, making it impossible to remove the cleaning layer for thorough cleaning. When replacing the cleaning layer, it must be replaced along with the track, resulting in higher consumable costs. This causes significant inconvenience for users.

[0004] Therefore, considering the aforementioned technical problems, it is necessary to provide a new technical solution. Summary of the Invention

The clean water tank is located on the side of the roller brush assembly away from the forward direction. The main body 4 also has a spray nozzle 46, which is located on one side, above, or slightly above the side of the roller brush assembly. In this example, the spray nozzle 46 is located on the inner surface of the upper cover 40, slightly above the side of the roller brush assembly. In this example, the spray nozzle 46 is connected to the clean water tank via a clean water pipe and a pump. The pump draws water from the clean water tank and sprays it onto the cleaning layer on the surface of the roller brush assembly through the clean water pipe and the spray nozzle.

[0062] In a preferred example, the roller brush assembly 10 further includes a timing belt 2, at least two rollers are provided on the roller component 3, the timing belt 2 is sleeved on the at least two rollers, an anti-slip structure is provided between the cleaning layer 1 and the timing belt 2, and the cleaning layer 1 is detachably sleeved on the timing belt 2 and rotates synchronously with the timing belt 2.

[0063] In the example, at least two rollers have a first anti-slip surface on their outer surfaces, and the inner wall of the timing belt 2 has a second anti-slip surface 211 that matches the first anti-slip surface of the rollers. The timing belt 2 is sleeved on at least two rollers.

[0064] The cleaning layer 1 is a sheet-like cleaning layer wrapped around the synchronous belt. A fixing strip 11 is provided on the sheet-like cleaning layer. An installation groove 221 is provided on the surface of the synchronous belt 2 along the axial direction. The fixing strip 11 is inserted into the installation groove 221.

The end of the sheet-like cleaning layer away from the fixing strip 11 can be detachably attached to the other end of the sheet-like cleaning layer or the surface of the synchronous belt 2.

[0065] In the example, the length directions of both the fixing strip 11 and the mounting groove 221 are perpendicular to the rotation direction of the roller brush assembly.

[0066] In the example, the surface of cleaning layer 1 is provided with roller brush bristles or roller brush strips.

[0067] In the example, at least two rollers are arranged horizontally at their bottoms, and the two rollers support the timing belt and the cleaning layer, so that the side of the cleaning layer closest to the area to be cleaned has a cleaning surface 101.

[0068] Preferably, one end of the sheet-like cleaning layer is attached to the other end using Velcro or steel pins. Of course, this patent is not limited to this, and Velcro or the like can also be used to attach it to the surface of the timing belt 2.

[0070] Further preferred, such as Figure 5-6 As shown, the surface of the synchronous belt 2 is also provided with a recess 222, which is connected to the mounting groove 221. At the position of the recess 222, one end of the sheet-like cleaning layer is attached to the surface of the other end of the sheet-like cleaning layer, and the surface of the cleaning layer after attachment is flat. Flat setting means that when one end of the sheet-like cleaning layer is attached to the other end, the surface of the cleaning layer will not have bulges or strips due to mutual adhesion, which will not affect the smooth movement of the roller brush assembly in close contact with the ground, nor will it affect the cleaning effect of the area to be cleaned. In the example, the recess 222 is set on one side of the mounting groove 221.

[0071] In the example, the settling tank 222 is located on the inside of the first end.

Preferably, the sheet-like cleaning layer includes a first end, a cleaning layer body, and a second end in the radial direction. At the position of the settling groove 222, the second end of the sheet-like cleaning layer is attached to the surface of the first end of the sheet-like cleaning layer, and the surface of the cleaning layer after attachment is flat. More preferably, the fixing strip 11 is disposed at the end of the first end close to the cleaning layer body or at the end of the first end far from the cleaning layer body. In the example, the fixing strip 11 is disposed at the end of the first end close to the cleaning layer body. Of course, this patent is not limited to this; the settling groove may not be provided, and after the second end is attached to the first end, the sum of the thicknesses of the first end and the second end is substantially the same as the thickness of the cleaning layer body. After the second end is attached to the first end, the surface of the cleaning layer is flat, without protrusions or depressions, etc.; or the thickness of the cleaning layer attached to the synchronous belt is uniform.

[0073] In a preferred embodiment, such as Figure 5-8 As shown, the synchronous belt 2 includes an inner synchronous belt 21 and an outer synchronous belt 22, with the outer synchronous belt 22 fixedly sleeved on the inner synchronous belt 21. Preferably, the inner synchronous belt 21 and the outer synchronous belt 22 are two synchronous belts of different materials or different hardnesses. Preferably, the hardness of the outer synchronous belt 22 is greater than the hardness of the inner synchronous belt 21. In the example, the outer synchronous belt 22 with higher hardness and the inner synchronous belt 21 with lower hardness are fixedly formed by a process, and the outer synchronous belt 22 and the inner synchronous belt 21 are not detachable; for example, formed by an overmolding or coating process.

[0074] In the example, the second anti-slip surface 211 is disposed on the inner wall of the inner synchronous belt 21. In the example, the second anti-slip surface 211 is provided with a plurality of anti-slip teeth at intervals, and the first anti-slip surface is provided with anti-slip grooves that mesh with the anti-slip teeth, and the first anti-slip surface meshes with the second anti-slip surface 211.

[0077] In a preferred embodiment, such as Figure 7-9As shown, the inner wall of the cleaning layer 1 is provided with protruding strips 12, and the surface of the outer synchronous belt 22 is provided with grooves 223 that match the protruding strips 12, with the protruding strips 12 accommodated in the grooves 223. Preferably, protruding strips 12 are provided on both symmetrical sides of the inner wall of the cleaning layer 1. Preferably, a plurality of protruding strips 12 are provided at intervals along the axial direction of the cleaning layer 1. In the example, the length direction of the protruding strips 12 is perpendicular to the axial direction of the cleaning layer 1. In the example, the grooves 223 are trapezoidal, V-shaped, or other shapes, etc., but this patent is not limited to these, with the aim of facilitating and stabilizing installation.

[0078] In a preferred embodiment, such as Figure 2-4 As shown, the roller component 3 also includes a support member 31, on which the roller is slidably mounted.

[0079] Preferably, the support member 31 includes a first support member 32 and a second support member 33, with the first support member 32 disposed on one side of the roller and the second support member 33 disposed on the other side of the roller. Of course, the first support member 32 and the second support member 33 can also be installed together, with the roller slidably mounted on the first support member 32 and the second support member 33.

[0080] Preferably, the support member 31 is provided with an extension 321, and a quick-release structure is provided between the extension 321 and the device body 4, so that the roller brush assembly can be detachably installed on the device body through the quick-release structure. In the example, the extension 321 is integrally provided on the first support member 32.

[0081] like Figure 2-4 As shown, in a preferred embodiment, the quick-release structure includes a magnetic structure. A magnetic element 3211 is provided on the extension 321, and a magnet matching the magnetic element is provided on the device body 4. The magnetic element 3211 is attracted to the magnet, allowing the roller brush assembly to be detachably attached to the cleaning device. In another preferred embodiment, the quick-release structure includes a snap-fit ​​structure. An elastic snap-fit ​​3212 is provided on the extension 321, and a snap-fit ​​protrusion 431 matching the elastic snap-fit ​​3212 is provided on the device body 4. The elastic snap-fit ​​3212 snaps onto the snap-fit ​​protrusion 431, and the roller brush assembly is snapped onto the cleaning device via the snap-fit ​​structure. Of course, both of the above quick-release structures can be provided simultaneously. In this example, both the magnetic element 3211 and the elastic snap-fit ​​3212 are provided on the first support member 32. In this example, an assembly groove 43 is provided on one outer surface of the device body, and both the magnet and the snap-fit ​​protrusion 431 are located in the assembly groove 43.

Furthermore, the drive motor 41 and the rotating gear 42 are located on the inner surface of the device body 4 away from the assembly groove 43.

[0082] Preferably, the rollers include at least a first roller and a second roller. In the example, the first roller is located on one side of the roller brush assembly in the forward direction, and the second roller is located on the side of the roller brush assembly closer to the water tank. More preferably, the outer diameter of the first roller is the same as the outer diameter of the second roller, or the outer diameter of the first roller is smaller than the outer diameter of the second roller. In the example, there are two rollers.

[0083] Preferred examples, such as Figure 4 As shown, at least one roller has a receiving cavity 34, and a drive motor fixed to the cleaning device is sealed and housed within the receiving cavity. The drive motor is configured to drive the roller to rotate. Preferably, the receiving cavity is located at one end of the second roller, and the outer diameter of the second roller is larger than the outer diameter of the first roller. In the example, the receiving cavity is located at the end of the first roller near the second support member.

[0084] The drive motor is fixedly mounted on the cleaning device. The drive end of the drive motor has a spline, and the bottom of the receiving cavity has an annular toothed groove that matches the spline. The drive motor drives the roller to rotate through the spline and the toothed groove. More preferably, the spline teeth are V-shaped, and the outward protrusion of the middle of the V-shaped teeth is opposite to the rotation direction of the roller brush assembly. This opposite orientation causes the roller brush assembly to tend to press towards the drive motor during rotation, ensuring that the roller brush assembly will not fall off or be thrown out during rotation.

[0085] Further preferred, such as Figure 2-4 As shown, a rotating groove 35 is formed at the end of the first roller near the second support member. A rotating tooth 42 is rotatably mounted on the cleaning device, and the rotating tooth 42 is engaged within the rotating groove 35. In this example, both the accommodating cavity and the rotating groove are located on the side near the second support member. In this example, both the accommodating cavity and the rotating groove pass through the second support member and communicate with the outside.

[0086] The bottom of the main body 4 of the equipment is also provided with an extension plate 47. The extension plate 47 is located on the side of the roller brush assembly away from the forward direction. The extension plate 47 extends to contact the area to be cleaned, so as to block and scrape away sewage and dirt on the area to be cleaned.
