[0002] As a type of household cleaning appliance, floor scrubbers are highly efficient at removing stains, dust, and other dirt from floors. They are versatile and suitable for cleaning various types of floors. The squeegee, a crucial component of the floor scrubber's brushes, is responsible for removing water residue and keeping the floor dry during the scrubber's forward and backward movements.

[0003] In related technologies, traditional floor scrubbers have a front squeegee in front of the roller brush. When pushing forward, the front squeegee does not contact the ground; when pulling back, the front squeegee contacts the ground to remove water stains. However, since the front squeegee is usually made of soft rubber, and the soft rubber is supported by a support frame, with the squeegee and the support frame connected by a rubber coating, the soft rubber of the front squeegee is prone to deformation after prolonged use, resulting in poor water removal and more water stains remaining on the ground.

[0039] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0040] The following is for reference. Figures 1-12 According to the present invention, the scraper assembly 100 can connect the scraper bracket 2, the scraper 1 and the scraper cover plate 3 into a whole, thereby improving the structural stability of the scraper 1 and ensuring the scraping effect of the scraper 1.

[0041] Combination Figures 1-12 As shown, the scraper assembly 100 according to a first aspect embodiment of the present invention includes a scraper 1, a scraper bracket 2, and a scraper cover plate 3. Wherein, along the cleaning direction of the cleaning equipment (e.g., ... Figure 1In the front-to-back direction of the roller brush, the scraper 1 can be located in front of the roller brush. The scraper 1 can be used to scrape off dirt (such as dust and water stains) on the surface to be cleaned, effectively improving the cleaning effect. The scraper bracket 2 and the scraper cover plate 3 can, to a certain extent, increase the structural strength of the scraper 1 and reduce the risk of deformation of the scraper 1 during the cleaning process.

[0042] Specifically, scraper 1 is provided with a thickness direction (i.e.) Figure 1 A mounting hole 11 (in the front-to-back direction) is provided. The scraper 1 is used to scrape away dirt (dust, water stains, etc.) on the surface to be cleaned. The scraper bracket 2 is provided on one side of the scraper 1, and the scraper cover plate 3 is provided on the other side of the scraper 1. One of the scraper bracket 2 and the scraper cover plate 3 is provided with a first mounting part 21. The first mounting part 21 passes through the mounting hole 11 and is connected to the other of the scraper bracket 2 and the scraper cover plate 3. That is to say, the first mounting part 21 can be provided on the scraper bracket 2 or the scraper cover plate 3.

[0043] For example, along the thickness direction of the scraper 1, the scraper bracket 2 and the scraper cover plate 3 are respectively connected to both sides of the scraper 1. The scraper 1 is provided with a through mounting hole 11, and the scraper bracket 2 is provided with a first mounting part 21. The first mounting part 21 connects to the scraper cover plate 3 after passing through the mounting hole 11 of the scraper 1. Thus, the scraper bracket 2, the scraper 1, and the scraper cover plate 3 are connected as a whole. The scraper bracket 2 and the scraper cover plate 3 form a stable clamp on the scraper 1 from both sides along the thickness direction, thereby increasing the structural stability of the scraper 1 during use. At the same time, the scraper bracket 2 and the scraper cover plate 3 can respectively strengthen the structural strength of local areas of the scraper 1 on both sides along the thickness direction. That is, without affecting the flexibility of the scraping area of ​​the scraper 1, the scraper bracket 2 and the scraper cover plate 3 can improve the scraper 1's resistance to deformation and reduce the risk of the scraper 1 easily deforming under external force, thereby ensuring the effectiveness of the scraper 1 in removing stains during cleaning.

[0044] Compared to traditional scraper assembly, which connects the scraper rubber to the scraper support frame by overmolding, the scraper assembly 100 of this utility model can effectively improve the scraper 1's resistance to deformation without affecting the flexibility of the scraping action. It also reduces the problem of poor water wiping effect caused by structural fatigue deformation of the scraper 1 after long-term use, thereby improving the practicality of the scraper 1 and extending its service life.

[0045] Therefore, by setting up the scraper assembly 100, the scraper bracket 2, the scraper 1 and the scraper cover plate 3 can be connected into a whole, thereby improving the structural stability of the scraper 1 and ensuring the water wiping effect of the scraper 1.

[0046] According to some optional embodiments of this utility model, the first mounting part 21 is connected to the other of the scraper bracket 2 and the scraper cover plate 3 by ultrasonic bonding. Ultrasonic bonding is a process that uses high-frequency mechanical vibration to generate heat to connect materials. It can quickly complete the welding task, improve work efficiency, and make the interconnected structures more robust, extending the product's service life. Therefore, using ultrasonic bonding is beneficial to improving the manufacturing efficiency of the scraper assembly 100 and the structural reliability of the scraper 1.

[0047] Specifically, refer to Figure 7 and Figure 8 The scraper bracket 2 and the scraper cover plate 3 are each provided with a mating groove 31, and the portion of the first mounting part 21 protruding from the mounting hole 11 is disposed within the mating groove 31. That is, when the first mounting part 21 is provided on the scraper cover plate 3, the scraper bracket 2 is provided with the mating groove 31; or, when the first mounting part 21 is provided on the scraper bracket 2, the scraper cover plate 3 is provided with the mating groove 31.

[0048] For example, the scraper bracket 2 is provided with a first mounting part 21, and the scraper cover plate 3 is provided with a mating groove 31 on the side facing the scraper 1. The protruding part of the first mounting part 21, after passing through the mounting hole 11 of the scraper 1, matches the mating groove 31. Thus, by utilizing the mating groove 31 and the end of the first mounting part 21, the scraper bracket 2, the scraper 1, and the scraper cover plate 3 are connected into a whole. In addition, the mounting hole 11 can position the first mounting part 21, thereby ensuring the relative positional accuracy between the scraper bracket 2 and the scraper 1; the mating groove 31 can position the first mounting part 21, ensuring the relative positional accuracy between the scraper bracket 2 and the scraper cover plate 3, thereby ensuring the relative positional accuracy of the three components, improving production efficiency and production quality.

[0049] According to some optional embodiments of this utility model, one of the scraper bracket 2 and the scraper cover plate 3 is provided with a second mounting part, and the first mounting part 21 is snap-fitted with the second mounting part (not shown in the figure). For example, the scraper bracket 2 is provided with a first mounting part 21, and the scraper cover plate 3 is provided with a second mounting part. The first mounting part 21 and the second mounting part are connected together by a snap-fit ​​connection. Compared with other connection methods, such as welding and screwing, the snap-fit ​​connection method is beneficial for users to disassemble and replace the scraper assembly 100, and can also reduce the use of additional fasteners and shorten the assembly time, thereby improving the convenience and economy of assembly and disassembly.

[0050] According to some alternative embodiments of this utility model, another of the scraper bracket 2 and scraper cover plate 3 is provided with a second mounting part, and the first mounting part 21 and the second mounting part are connected by fasteners (not shown in the figure). For example, the scraper bracket 2 is provided with a first mounting part 21, and the scraper cover plate 3 is provided with a second mounting part. The first mounting part 21 and the second mounting part are connected together by fasteners. Compared with other connection methods, such as welding and bonding, the screw connection method is more convenient for users to disassemble and replace the scraper assembly 100, thereby improving the ease of assembly and disassembly. At the same time, the fasteners further ensure the connection stability of the first mounting part 21 and the second mounting part.

[0051] According to some alternative embodiments of the present invention, referring to Figure 3 and Figure 4 A guide head 211 is provided at one end of the first mounting part 21 away from one of the scraper bracket 2 and scraper cover plate 3. The width of the guide head 211 decreases in the direction away from one of the scraper bracket 2 and scraper cover plate 3.

[0052] For example, the scraper bracket 2 is provided with a first mounting part 21, and the first mounting part 21 has a guide head 211 at the end away from the scraper bracket 2, and the width of the guide head 211 gradually decreases in the direction away from the scraper bracket 2. Alternatively, the scraper cover plate 3 is provided with a first mounting part 21, and the first mounting part 21 has a guide head 211 at the end away from the scraper cover plate 3, and the width of the guide head 211 gradually decreases in the direction away from the scraper cover plate 3. This makes it easier for the guide head 211 to accurately locate the mounting hole 11 on the scraper 1, facilitating alignment and ensuring correct orientation, thereby providing a guiding effect for the first mounting part 21 and improving the assembly efficiency of the scraper assembly 100.

[0053] According to some optional embodiments of the present invention, refer to Figures 2-5 The first mounting part 21 is constructed as a long, narrow mounting rib 4, and the mounting hole 11 is also long and narrow. This arrangement allows for a better match between the shapes of the first mounting part 21 and the mounting hole 11, and also reasonably extends the mating area between them, which helps ensure the reliability and stability of the fit. Furthermore, the manufacturing process of the first mounting part 21 and the mounting hole 11 is relatively simple, improving manufacturing efficiency and thus enhancing its practicality.

[0054] Optionally, refer to Figure 9 and Figure 11The first mounting part 21 includes multiple elongated mounting ribs 4, which are arranged intersectingly. The mounting hole 11 includes multiple elongated mounting sub-holes, which are also arranged intersectingly, and each sub-hole corresponds to one mounting rib 4. In the description of this utility model, "multiple" means two or more. Therefore, by increasing the number of mounting ribs 4 and mounting sub-holes, it is beneficial to increase the connection area and force transmission path between the first mounting part 21 and the scraper cover plate 3, thereby effectively improving the connection strength and force uniformity between the scraper bracket 2 and the scraper cover plate 3, and thus improving the connection stability and firmness between the two.

[0055] For example, multiple mounting ribs 4 on the scraper bracket 2 are arranged in a cross pattern, and multiple mounting sub-holes on the scraper 1 are arranged in a corresponding cross pattern. This can effectively distribute stress in at least two directions of the mounting sub-holes, reduce stress concentration caused by the unidirectional arrangement of the mounting ribs 4, thereby improving the uniformity of stress distribution between the two and thus improving the deformation resistance of the scraper 1.

[0056] According to some optional embodiments of the present invention, there are multiple mounting holes 11, which are arranged in rows and / or columns on the scraper 1. There are multiple first mounting parts 21, which are arranged in rows and / or columns on one of the scraper bracket 2 and the scraper cover plate 3. The multiple first mounting holes 11 correspond one-to-one with the multiple first mounting parts 21.

[0057] Understandably, this arrangement allows for a more balanced distribution of forces, reducing localized stress concentrations and thus making the structure connected and installed using the mounting holes 11 more stable. It also ensures precise matching between the first mounting part 21 and the corresponding mounting hole 11, improving the accuracy and efficiency of assembly and reducing installation errors and adjustment time. Furthermore, this standardized layout simplifies the design of production molds and assembly tools, thereby improving manufacturing efficiency and reducing manufacturing costs. For example, on automated production lines, a uniform row and / or column arrangement facilitates machine positioning and automated assembly, thereby improving manufacturing efficiency.

[0058] According to some optional embodiments of the present invention, refer to Figures 10-12 The scraper bracket 2 is provided with a first prepositioning part 22, and the scraper 1 is provided with a second prepositioning part 12. The first prepositioning part 22 and the second prepositioning part 12 cooperate with each other.

[0059] The first pre-positioning part 22 on the scraper bracket 2 and the second pre-positioning part 12 on the scraper 1 cooperate with each other. This arrangement can further fix the relative position between the two, thereby improving the overall structural consistency of the two; it can also achieve the effect of pre-installation positioning, thereby improving the installation accuracy and efficiency. In the actual installation process, the first pre-positioning part 22 and the second pre-positioning part 12 can be positioned first, so that the first mounting part 21 can be accurately located and fitted into the mounting hole 11.

[0060] Specifically, the first prepositioning part 22 is constructed as one of a long strip-shaped prepositioning rib and a prepositioning groove, and the second prepositioning part 12 is constructed as one of a long strip-shaped prepositioning rib and a prepositioning groove.

[0061] In other words, the first prepositioning part 22 is configured as a prepositioning rib, and the second prepositioning part 12 is configured as a prepositioning groove; or, the first prepositioning part 22 is configured as a prepositioning groove, and the second prepositioning part 12 is configured as a prepositioning rib. At least a portion of the prepositioning rib can be fitted into the prepositioning groove, thus achieving a prepositioning effect during the assembly of the scraper bracket 2 and the scraper 1, thereby improving the installation efficiency and accuracy between the two, and also creating a limiting effect between them, thereby improving the positional stability between them.

[0062] According to some optional embodiments of this utility model, such as Figure 1 As shown, the scraper blade 1 is provided with an elastic support block 13, and the scraper blade cover plate 3 is provided with a support groove 32, with the elastic support block 13 disposed in the support groove 32. Thus, on the one hand, the elastic support block 13 can effectively improve the support strength of the scraper blade 1, thereby reducing the risk of deformation of the scraper blade 1; on the other hand, the support groove 32 provides installation space for the elastic support block 13, which can, to a certain extent, limit the relative relationship between the scraper blade 1 and the scraper blade cover plate 3, preventing the scraper blade 1 from detaching from the scraper blade cover plate 3, thereby improving the overall structural consistency of the scraper blade assembly 100.

[0063] According to a second aspect embodiment of the present invention, a scraper assembly 100 includes a scraper 1, a scraper bracket 2, and a scraper cover plate 3. The scraper 1 is provided with a mounting hole 11 extending through it along its thickness direction. The scraper bracket 2 is provided on one side of the scraper 1, and the scraper cover plate 3 is provided on the other side of the scraper 1. One of the scraper bracket 2 and the scraper cover plate 3 is provided with a long strip-shaped mounting rib 4, which passes through the mounting hole 11 and is connected to the other of the scraper bracket 2 and the scraper cover plate 3.

[0064] Specifically, along the direction in which the cleaning head moves back and forth on the surface to be cleaned, the scraper cover plate 3 and the scraper bracket 2 are located on the front and rear sides of the scraper 1, respectively. The scraper bracket 2 and the scraper cover plate 3 are separated by the scraper 1. The scraper 1 is provided with mounting holes 11. The scraper bracket 2 and the scraper cover plate 3 can be smoothly connected through the cooperation of the mounting ribs 4 and the mounting holes 11. For example, the scraper bracket 2 is provided with mounting ribs 4. The mounting ribs 4 on the scraper bracket 2 pass through the mounting holes 11 and extend to the scraper bracket 2 to establish a connection relationship. This allows the front and rear sides of the scraper 1 to abut against the scraper cover plate 3 and the scraper bracket 2, respectively, and establish a large-area contact connection. This facilitates the connection of the scraper bracket 2, the scraper 1, and the scraper cover plate 3 into a whole, thereby improving the structural stability of the scraper 1.

[0065] According to a third aspect embodiment of the present invention, a scraper assembly 100 includes a scraper 1, a scraper bracket 2, and a scraper cover plate 3. The scraper 1 is provided with a mounting hole 11 extending through it along its thickness direction. The scraper bracket 2 is provided on one side of the scraper 1, and the scraper cover plate 3 is provided on the other side of the scraper 1. One of the scraper bracket 2 and the scraper cover plate 3 is provided with a plurality of elongated mounting ribs 4. The plurality of mounting ribs 4 are arranged crosswise and pass through the mounting hole 11. At least one mounting rib 4 is connected to the other of the scraper bracket 2 and the scraper cover plate 3.

[0066] Along the direction in which the cleaning head moves back and forth on the surface to be cleaned, the scraper cover plate 3 and the scraper bracket 2 are located on the front and rear sides of the scraper 1, respectively. The scraper bracket 2 and the scraper cover plate 3 are separated by the scraper 1. The scraper 1 is provided with mounting holes 11, and the scraper bracket 2 and the scraper cover plate 3 can be smoothly connected through the mounting holes 11. For example, the scraper bracket 2 is provided with multiple mounting ribs 4. The multiple mounting ribs 4 on the scraper bracket 2 pass through the mounting holes 11 and extend to the scraper bracket 2 to establish a connection relationship with the scraper cover plate 3. The front and rear sides of the scraper 1 can abut against the scraper cover plate 3 and the scraper bracket 2 to establish a large-area contact connection relationship. This can improve the connection strength between the front and rear sides of the scraper 1 and the scraper bracket 2 and the scraper cover plate 3, thereby improving the structural stability of the scraper 1 and avoiding the risk of the scraper 1 being easily deformed.

[0067] Specifically, the plurality of mounting ribs 4 include a first mounting rib 41 and a second mounting rib 42, the middle part of the first mounting rib 41 and the middle part of the second mounting rib 42 are intersected, and the first mounting rib 41 and the second mounting rib 42 are perpendicular to each other.

[0068] The above arrangement can effectively improve the bending and torsional resistance of the scraper assembly 100, and can also make the stress more evenly distributed in two directions, avoiding stress concentration due to a single force direction, extending the service life of the structure. Moreover, the design of the first mounting rib 41 and the second mounting rib 42 perpendicularly intersecting is simpler and clearer, and facilitates manufacturing and assembly.

[0069] The cleaning device according to the fourth aspect of the present invention includes the scraper assembly 100 of the above embodiment. The cleaning device having the scraper assembly 100 can improve the structural stability of the scraper 1, reduce the risk of deformation of the scraper 1 during the cleaning process, ensure the water scraping effect of the scraper 1, and improve the market competitiveness of the cleaning device.
