Detailed Implementation

[0018] Various embodiments of this application will be described more fully below. This application may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of this application to the specific embodiments disclosed herein, but rather this application should be understood to cover all adjustments, equivalents, and / or alternatives falling within the spirit and scope of the various embodiments of this application.

[0019] In the following, the terms “comprising” or “may include” as used in the various embodiments of this application indicate the presence of the disclosed functions, operations, or elements, and do not limit the addition of one or more functions, operations, or elements. Furthermore, as used in the various embodiments of this application, the terms “comprising,” “having,” and their cognates are intended only to indicate a particular feature, number, step, operation, element, component, or combination of the foregoing, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing, or the possibility of adding one or more combinations of features, numbers, steps, operations, elements, components, or combinations of the foregoing.

[0020] Example 1 like Figure 1 , 2 As shown, a floor scraper 1 includes: The connecting part 11 is used to connect to the bottom of the cleaning unit 2; The scraper has one end connected to the connecting part 11 and the other end extending away from the bottom of the cleaning host 2. It is used to contact the ground when the cleaning host 2 moves to scrape off dirt and water from the ground. The first reinforcing part 13 and the second reinforcing part 14 are provided on the front side of the scraping part and the second reinforcing part 14 are provided on the back side of the scraping part. The first reinforcing part 13 and the second reinforcing part 14 are both distributed along the length direction of the scraping part. The first reinforcing part 13 and the second reinforcing part 14 work together to strengthen the strength of the scraping part.

[0021] This application improves the stability of the structure by means of the combined action of the first reinforcing part 13 and the second reinforcing part 14 on the scraper, avoids bending deformation of the scraper due to excessive local stress, and ensures that the scraper maintains effective contact with the ground, thereby improving the cleaning effect.

[0022] like Figure 1 , 3 As shown, the first reinforcing part 13 includes ribs 131, which are disposed on the front side of the scraper part. The ribs 131 extend along the length direction of the scraper part, and the ratio of the extension length of the ribs 131 to the length of the scraper part is between 0.9 and 1. By setting the ratio of the extension length of the ribs 131 of the first reinforcing part 13 to the length of the scraper part to 0.9-1, this invention achieves near-full-length reinforcement coverage of the scraper part, further strengthening its strength and preventing bending deformation caused by excessive local stress. This ensures that the scraper part maintains effective contact with the ground, improving the cleaning effect.

[0023] like Figure 1 , 4 As shown, the second reinforcing part 14 includes a plurality of protruding teeth 141, which are disposed on the back side of the scraper part and spaced apart along the length direction of the scraper part. This application forms a discrete reinforcing structure by providing a plurality of protruding teeth 141 spaced apart along the length direction on the back side of the scraper part. This discrete reinforcing structure, in conjunction with conventional continuous reinforcing ribs, further strengthens the scraper part, preventing bending deformation caused by excessive local stress, ensuring continuous and effective contact between the scraper part and the ground, and improving the cleaning effect.

[0024] The cross-sectional shape of the protruding tooth 141 includes triangles, rectangles, arcs, or irregular shapes. The cross-sectional shape of the protruding tooth 141 includes centrally symmetric, axisymmetric, or asymmetrical shapes.

[0025] In this application, the cross-sectional shape of the protruding tooth 141 is teardrop-shaped.

[0026] like Figure 1-4As shown, both the first reinforcing part 13 and the second reinforcing part 14 are located near the end of the scraper that contacts the ground. This application achieves precise reinforcement of the scraping action area by placing both the first reinforcing part 13 (rib 131) and the second reinforcing part 14 (tooth 141) in the end region of the scraper that is close to the ground. Compared to traditional full-length reinforced structures, this design creates a dual-reinforcement system in the working section where the stress is most concentrated (such as the 10-20mm area at the end in contact with the ground). The rib 131 provides longitudinal stiffness support, and the tooth 141 enhances lateral stability; the synergistic effect of both significantly improves the bending strength at the end.

[0027] The first reinforcing part 13 has a first projection on the scraping part, and the second reinforcing part 14 has a second projection on the scraping part, with at least a portion of the first projection and the second projection overlapping. This application creates a three-dimensional, intersecting reinforcing structure on both sides by ensuring that the projections of the first reinforcing part 13 (rib 131) and the second reinforcing part 14 (tooth 141) on the scraping part at least partially overlap. This improves the rigidity of the scraping part, prevents bending deformation caused by excessive local stress, and ensures continuous and effective contact between the scraping part and the ground, thus improving the cleaning effect.

[0028] like Figure 1-4 As shown, the connecting part 11 and the scraper part form a preset angle α, which is between 90° and 160°. This application achieves precise control of the contact angle between the scraper and the ground by setting the preset angle between the connecting part 11 and the scraper part to 90°-160°. When the preset angle between the connecting part 11 and the scraper part is close to 90°, the scraping force is transmitted vertically, suitable for removing stubborn stains on hard floors such as tiles; when the preset angle between the connecting part 11 and the scraper part is close to 160°, the scraper part flexibly conforms, suitable for removing deep dirt from soft floors such as carpets.

[0029] Among them, such as Figure 1-5 As shown, the area of ​​the connecting part 11 is larger than the area of ​​the scraping part. This application achieves the stability of the floor scraper 1 and the cleaning host 2 by connecting the larger area connecting part 11; at the same time, it achieves the scraping of the floor by using the smaller area scraping part, which improves the stability of the scraping part when scraping, and makes the overall structure reasonable, compact and small.

[0030] Example 2 like Figure 1-5 As shown, a cleaning device includes a cleaning main unit 2 and at least two floor scrapers 1, which are spaced apart along the length or width of the cleaning main unit 2. This application, by arranging at least two floor scrapers 1 spaced apart along the length / width of the cleaning main unit 2, creates a multi-stage scraping effect to remove large particles of dirt and wastewater from the floor, thereby greatly improving the cleaning effect.

[0031] like Figure 1-5 As shown, the bottom of the cleaning unit 2 is provided with a roller brush 3 for contacting the ground, and a floor scraper 1 is provided on the front side and / or the rear side of the roller brush 3. By setting the floor scraper 1 on the front side and / or the rear side of the roller brush 3, this application constructs a system in which the roller brush 3 rolls and scrubs the ground, and the floor scraper 1 removes large particles of dirt and sewage, greatly improving the cleaning effect.

[0032] In one embodiment, the bottom of the cleaning unit 2 is provided with two roller brushes 3, which are spaced apart. The floor scraper 1 includes a first floor scraper 101 and a second floor scraper 102. Each roller brush 3 corresponds to a first floor scraper 101 and a second floor scraper 102. The first floor scraper 101 is located on the front side of the roller brush 3, and the second floor scraper 102 is located on the rear side of the roller brush 3. Through the positional design of the first floor scraper 101-roller brush 3-second floor scraper 102, a three-level cleaning system of scraping-brushing-scraping is constructed. The first floor scraper 101 is responsible for pre-scraping away large particles of dirt and excess water. The roller brush 3 rotates to deeply clean the floor crevices and pick up stubborn dirt. The second floor scraper 102 performs the final scraping and wastewater recycling.

[0033] The area of ​​the connecting part of the first ground scraper 101 is larger than the area of ​​the connecting part of the second ground scraper 102.

[0034] In other embodiments, the bottom of the cleaning unit 2 is provided with two roller brushes 3, which are spaced apart. Each roller brush 3 corresponds to a floor scraper 1, which is located on the front or rear side of the roller brush 3. The floor scraper 1 is either the first floor scraper 101 or the second floor scraper 102 mentioned above.

[0035] like Figure 1-5 As shown, a fastener (not shown) is provided between the connecting part 11 and the cleaning unit 2, and the connecting part 11 is detachably connected to the cleaning unit 2 via the fastener. The fastener includes screws, bolts, etc. This application utilizes the feature of the connecting part 11 being detachably connected to the cleaning unit 2 via fasteners, allowing the floor scraper 1 to be detachably connected to the cleaning unit 2, thereby facilitating subsequent repair and replacement of the floor scraper 1 in case of damage.

[0036] Specifically, the connecting part 11 has a fixing hole 111, through which a fastener passes and is connected to the cleaning host 2.
