[0050] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0051] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0052] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0053] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0054] like Figure 1-3As shown, this embodiment provides a combined vacuum cleaner floor brush assembly including a floor brush main body 100 and a mopping main body 200. The floor brush main body 100 includes a floor brush bottom S, and the front side of the floor brush bottom S is provided with an air inlet 11 in the width direction. The mopping main body 200 includes a water tank 21 made of plastic and a rag. The water tank 21 includes a bottom, a peripheral side and a top. The bottom of the water tank extends forward to form an extension plate F. A concave-convex positioning structure is provided between the upper surface of the extension plate F and the floor brush bottom S. A snap-fit ​​connection structure is provided between the upper surface of the extension plate F and the floor brush bottom S. When the extension plate F is placed on the rear side of the floor brush bottom S, the mopping main body 200 is assembled with the floor brush main body 100 through the cooperation of the concave-convex positioning structure and the snap-fit ​​connection structure.

[0055] It should be recognized that the combination of the concave-convex positioning structure and the snap-on connection structure not only ensures a secure connection between the mopping body 200 and the floor brush body 100, but also improves the reliability and durability of the connection, reducing the problem of poor cleaning results caused by loosening or falling off. Compared with the magnetic connection method, the connection method of the floor brush body 100 and the mopping body 200 in this embodiment has no special requirements for materials and can be made of plastic, thereby achieving an integrated molding of the water tank 21 and the extension plate F and achieving lightweight.

[0056] like Figure 2 、 3 As shown in Figures 7 and 7, the concave-convex positioning structure includes raised positioning blocks 1 respectively provided on the left and right sides of the upper surface of the extension plate F and positioning holes 2 provided on the left and right positions behind the air inlet 11 of the bottom S of the floor brush.

[0057] like Figure 2-4 As shown in Figures 7 and 8, the concave-convex positioning structure includes a raised connecting portion 20 in the middle of the extension plate F and a recessed connecting hole 10 in the middle of the floor brush base S. The snap-fit ​​connection structure includes at least one hook 3 on the raised connecting portion 20 and a rib 4 on the wall of the recessed connecting hole 10 for connecting with the hook 3. When the extension plate F is placed behind the floor brush base S, the raised positioning block 1 on the extension plate F engages with the positioning hole 2, the raised connecting portion 20 enters the recessed connecting hole 10, and the hook 3 hooks onto the rib 4, thereby assembling the mopping body 200 with the floor brush body 100.

[0058] The concave-convex positioning structure precisely positions the mop body 200 and the floor brush body 100 in the left-right direction by matching the raised positioning block 1 on the extension plate F with the positioning hole 2 on the bottom S of the floor brush. This design ensures accurate alignment of the two during assembly, avoiding assembly difficulties or poor cleaning results caused by misalignment. Furthermore, the mating of the raised connecting portion 20 with the recessed connecting hole 10, and the locking connection between the hook portion 3 and the rib 4, further enhance the stability of the connection. This multiple positioning and locking mechanism prevents the mop body 200 and the floor brush body 100 from loosening or falling off after assembly, ensuring stability and reliability during the cleaning process.

[0059] Furthermore, the coordinated design of the concave-convex positioning structure and the snap-fit ​​connection structure makes the assembly process of the mopping body 200 and the floor brush body 100 simple and quick. The user simply places the extension plate F behind the floor brush base S. The raised positioning block 1 automatically snaps into the positioning hole 2, and the raised connecting portion 20 smoothly enters the concave connecting hole 10. Subsequently, the hook portion 3 locks with the rib 4, completing the entire assembly process. This design greatly simplifies the assembly process and improves assembly efficiency.

[0060] like Figure 1 、 4 As shown in Figures 5 and 6, the rear side of the floor brush body 100 is rotatably connected to the accessory connector 300. The rear side of the floor brush body 100 is provided with a rear air guide hole 12 connected to the air inlet 11. A flexible air guide duct 400 is provided between the rear air guide hole 12 and the accessory connector 300. The concave connection hole 10 is provided on the lower side of the flexible air guide duct 400, and the rib 4 is provided on the inner wall of the concave connection hole 10. The upper surface of the raised connection part 20 is provided with a concave arcuate surface E. The upper surface of the raised connection part 20 is an arcuate surface that matches the flexible air guide duct 400. Therefore, the provision of the concave arcuate surface E not only serves to avoid the flexible air guide duct 400, but also further supports the flexible air guide duct 400 and guides the movement of the flexible air guide duct 400 with the accessory connector 300.

[0061] like Figure 5-6As shown, the raised connection portion 20 includes a left petal-shaped wall 5, an intermediate body 7 and a right petal-shaped wall 6. A first gap groove is provided between the left petal-shaped wall 5 and the intermediate body 7, and a second gap groove is provided between the right petal-shaped wall 6 and the intermediate body 7. The outer side of the upper end of the left petal-shaped wall 5 has a left hook portion, and the outer side of the upper end of the right petal-shaped wall 6 has a right hook portion. A left convex rib is provided on the left hole wall of the concave connection hole 10, and a right convex rib is provided on the right hole wall of the concave connection hole 10. The left hook portion is hooked on the left convex rib, and the right hook portion is hooked on the right convex rib. The design of the left petal-shaped wall 5 and the right petal-shaped wall 6 allows them to have a certain elastic deformation relative to the intermediate body 7. This design allows the petal-shaped body to be deformed by applying external force when the connection needs to be disassembled, so that it can be easily detached from the convex rib 4, realizing a convenient disassembly process, and also reducing the wear of the hook portion 3, so that the service life of the structure is longer. In addition, due to the elasticity of the petal-shaped body, the hook part 3 can fit tightly against the rib 4 after being hooked, and is not easy to loosen, thereby improving the firmness of the connection. It also has certain shock resistance and anti-loosening capabilities. When subjected to external force impact or vibration, the elasticity of the petal-shaped body can absorb part of the energy, reduce the risk of loosening of the connection part, and ensure the stability and durability of the connection.

[0062] like Figure 5-6 As shown, the intermediate body 7 includes a front wall 71, a rear wall, and a top wall 73. The left petal-shaped wall 5 forms the left wall of the raised connection portion 20, and the right petal-shaped wall 6 forms the right wall of the raised connection portion 20. The front wall 71 and the rear wall exceed the top wall 73 in the left and right directions to form empty groove areas M on both sides, respectively. The left petal-shaped wall 5 and the right petal-shaped wall 6 are respectively located in the corresponding empty groove areas M. The front sides of the left and right walls are separated from the front wall, and the rear sides of the left and right walls are separated from the rear wall. This structure further enhances the elasticity of the petal-shaped body, which is not only convenient for disassembly, but also may provide a certain degree of fault tolerance during the installation process. For example, even if there is a certain position deviation during installation, the petal-shaped body can adapt to and correctly hook onto the rib 4 through elastic deformation, thereby improving the flexibility and success rate of installation.

[0063] like Figure 6 As shown, outwardly extending reinforcement walls K are provided on both sides of the top wall 73. This effectively increases the overall strength and rigidity of the intermediate body 7, enabling it to better resist deformation when subjected to external forces, thereby improving the stability and durability of the entire structure. The presence of the reinforcement walls K optimizes the distribution of stress within the intermediate body 7, reduces stress concentration, helps prevent structural damage caused by excessive local stress, and further extends the product's service life. During the plug-in process, the reinforcement walls K provide a certain degree of resistance and support for the petaloids, preventing them from being excessively squeezed and deformed due to excessive plug-in forces.

[0064] like Figure 5As shown, there are two raised positioning blocks 1, and the raised connecting portion 20 is located at the rear side of the center line connecting the two raised positioning blocks 1. According to the stability principle of the triangle, three non-collinear points can determine a plane, and the triangular structure has excellent stability and anti-deformation ability when subjected to external forces. In the present technical solution, the two raised positioning blocks 1 and one raised connecting portion 20 together constitute the three vertices of the triangle, so that the entire structure can remain stable and not easily deformed when subjected to external forces. The three connection points of the triangle not only enhance the stability of the structure, but also improve the strength of the connection parts. When the floor brush main body 100 and the mopping main body 200 are connected and fixed together, the triangular structure enables each connection point to withstand greater tension and shear force, thereby improving the connection strength of the entire structure.

[0065] like Figure 1 、 3 As shown in Figures 7 and 7, a recessed area N is provided at the bottom of the water tank 21, and the extension plate F cooperates with the recessed area N, thereby improving the flatness of the bottom surface of the floor brush assembly after connection, improving the stability of the water tank 21 when placed, and ensuring safe use.

[0066] like Figure 3 、 7 As shown, the bottom of the water tank 21 is equipped with Velcro 9, through which the rag is attached. A water seepage hole is provided at the bottom of the water tank 21, allowing the liquid inside to seep onto the rag. The air inlet 11 is rectangular along the left and right widths. An electrostatic strip 40 and a flexible dust scraping strip 50 are located between the air inlet 11 and the positioning hole 2. A concave and convex air guide structure is provided in front of the air inlet 11. Preferably, the bottom of the water tank 21 is rectangular, with strips of Velcro 9 located on the inner sides of each of the four sides to ensure secure attachment of the rag.

[0067] The above describes the combined vacuum cleaner floor brush assembly provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The above examples are intended only to facilitate understanding of the present invention and its core concepts.
