[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part of the device. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper" and "lower," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] This embodiment provides a mop assembly and a sweeping robot. The sweeping robot includes a housing and the mop assembly provided in this embodiment, which is detachably mounted on the housing. Equipped with this mop assembly, the sweeping robot can stably and efficiently handle floor stains during cleaning. Routine maintenance and mop assembly replacement are simple and convenient, reducing the difficulty of use. Simultaneously, the mop assembly reduces the probability of malfunction and energy consumption, thereby indirectly extending the sweeping robot's runtime and improving overall performance and ease of use.

[0039] It is worth noting that the sweeping machine involved in this embodiment, except for the mop assembly, has other structures that are existing technologies and will not be described in detail here.

[0040] like Figures 1-9As shown, the mop assembly includes a bracket 1, a mop tray 2, and a mop (not shown in the figure). One side of the bracket 1 can be detachably connected to the bottom surface of the sweeper's housing, and the other side of the bracket 1 is detachably connected to the mop tray 2. The mop covers the mop tray 2, which includes a hard rubber layer 21 and a soft rubber layer 22. The hard rubber layer 21 abuts against the side of the bracket 1 away from the housing, and the soft rubber layer 22 is connected to the side of the hard rubber layer 21 away from the bracket 1 and fits against the mop. During installation, the bracket 1 is first installed on the bottom surface of the sweeper's housing. After the mop covers the mop tray 2, it is fastened to the bracket 1. The bracket 1 and the mop tray 2 clamp the edge of the mop, and the mop fits tightly against the soft rubber layer 22 of the mop tray 2. When replacing the mop, there is no need to disassemble the bracket 1. Unfasten the bracket 1 and the mop tray 2, peel off the old mop covering the mop tray 2, and then cover the mop tray 2 with a new mop and fasten it to the bracket 1. The hard rubber layer 21 of the mop head 2 abuts against the bracket 1, while the soft rubber layer 22 adheres to the mop head. This ensures the overall structural stability while promoting a closer fit between the mop head and the floor, enhancing cleaning performance. The simple structure of this mop assembly reduces the use of complex components, effectively controlling production costs. During later maintenance, the simple structure allows for easy disassembly and replacement of damaged parts, facilitating user operation or quick repair by professionals. It also reduces the risk of malfunctions caused by complex structures, improving the stability and reliability of the sweeper, indirectly extending battery life, comprehensively optimizing the user experience, and ensuring cleaning quality.

[0041] Specifically, mops can be made from used face towels, microfiber mops, or cotton mops. Used face towels are soft and can be reused for cleaning floors, offering both environmental and cost advantages. Microfiber mops have extremely fine fibers, providing powerful stain removal, excellent water absorption, and durability. Cotton mops are naturally skin-friendly and, when used with detergents, can remove stubborn grease. Users can choose the appropriate type of mop according to their needs to achieve the best cleaning results.

[0042] Specifically, the hard rubber layer 21 can be made of ABS material, and the soft rubber layer 22 can be made of TPU material. ABS material has good strength, hardness, and rigidity, which can provide a stable support structure for the mop head 2, ensuring that it can maintain its shape and mechanical properties when subjected to the weight of the mop and external forces such as friction and impact with the ground during cleaning, so that the mop assembly has a reliable frame during operation. TPU material has good flexibility, wear resistance, and elasticity. As the soft rubber layer 22 in contact with the ground and mop head, its flexibility allows the mop head to better conform to various undulations and unevenness of the ground, ensuring comprehensive and thorough cleaning; its wear resistance can reduce wear during long-term floor wiping, extending the service life of the soft rubber layer 22; its elasticity helps to cushion when encountering obstacles or uneven ground, protecting the mop assembly itself and reducing the impact on the ground and the sweeper, further improving the stability and reliability of the sweeper during cleaning operations. At the same time, the characteristics of the two materials complement each other and work synergistically to optimize the cleaning performance and user experience of the mop assembly.

[0043] It is worth noting that the materials used for the hard rubber layer 21 and the soft rubber layer 22 are not specifically limited. The hard rubber layer 21 can also be made of engineering plastics such as polycarbonate (PC). PC can withstand large external forces, has good dimensional stability and heat resistance, and is suitable for various cleaning environments. The soft rubber layer 22 can also be made of thermoplastic rubber (TPR). TPR also has flexibility and elasticity, achieving similar bonding and cushioning functions at a lower cost. Blends of natural or synthetic rubber are also available; performance requirements can be met through formula adjustments. In actual design and production, materials are flexibly selected based on comprehensive performance indicators, cost, and process factors to achieve the best balance between performance and economic benefits for the mop assembly; materials are not strictly limited.

[0044] In this embodiment, as Figure 6 and Figure 7 As shown, one of the soft rubber layer 22 and the hard rubber layer 21 has multiple connecting protrusions 221, and the other of the soft rubber layer 22 and the hard rubber layer 21 has multiple connecting holes 211 at corresponding positions of the multiple connecting protrusions 221. The connecting protrusions 221 and the connecting holes 211 are interference-fitted. The tight fit between the connecting protrusions 221 and the connecting holes 211 enhances the stability of the connection between the soft rubber layer 22 and the hard rubber layer 21, effectively preventing relative displacement or separation between the two during frequent use of the mop assembly, and ensuring the reliability and stability of the overall structure of the mop assembly.

[0045] In this embodiment, as Figure 7 As shown, the soft adhesive layer 22 has multiple connecting protrusions 221, such as... Figure 6As shown, the hard adhesive layer 21 has multiple connecting holes 211 at corresponding positions to the multiple connecting protrusions 221, and the connecting protrusions 221 and the connecting holes 211 are press-fitted one by one. In other optional embodiments, the hard adhesive layer 21 has multiple connecting protrusions 221, and the soft adhesive layer 22 has multiple connecting holes 211 at corresponding positions to the multiple connecting protrusions 221, and the connecting protrusions 221 and the connecting holes 211 are press-fitted one by one, which can also achieve the above effect.

[0046] Furthermore, in addition to the interference fit between the connecting protrusion 221 and the connecting hole 211, the soft adhesive layer 22 and the hard adhesive layer 21 can also be fixed by adhesive bonding to further enhance the tightness of the connection between them. The adhesive can fill the tiny gaps between the soft adhesive layer 22 and the hard adhesive layer 21, which not only enhances the connection strength but also plays a certain role in sealing, preventing dust, moisture and other impurities from entering between the two layers and affecting the connection effect or causing a decline in material performance.

[0047] In this embodiment, as Figure 9 As shown, the soft rubber layer 22 partially covers the hard rubber layer 21, and on the side near the support 1, the surfaces of the soft rubber layer 22 and the hard rubber layer 21 are flush, making the connection interface between the soft rubber layer 22 and the hard rubber layer 21 more stable.

[0048] In this embodiment, as Figure 8 As shown, the soft rubber layer 22 has multiple cylindrical teeth 222 on the surface away from the hard rubber layer 21. These cylindrical teeth 222 enhance the friction between the soft rubber layer 22 and the mop, preventing the mop from slipping and falling off, thus ensuring a smooth cleaning operation. When mopping, the cylindrical teeth 222 "rub" away dirt from the floor, cleaning more thoroughly than a flat surface, and can also reach into floor crevices to remove dust and grime, improving overall cleaning effectiveness. Simultaneously, the cylindrical teeth 222 cushion the impact of floor bumps or obstacles, protecting the soft rubber layer 22, the mop, and the internal components of the sweeper, reducing bumps during operation, maintaining stable operation, extending the overall lifespan of the machine, and improving the user experience.

[0049] Specifically, such as Figure 3 As shown, the cylindrical teeth 222 are cylindrical, and multiple cylindrical teeth 222 are spaced apart on the surface of the soft rubber layer 22 away from the hard rubber layer 21. It is worth noting that the cylindrical teeth 222 can also be rectangular, hemispherical, or other shapes, and are not specifically limited here.

[0050] In this embodiment, as Figure 6 As shown, the hard rubber layer 21 has multiple weight-reducing holes 212. These holes 212 reduce the weight of the hard rubber layer 21 and the mop assembly, thus lowering the robot vacuum's energy consumption and extending its runtime and cleaning range. Figure 6As shown, the weight-reducing holes 212 are hexagonal and spaced apart on the hard adhesive layer 21. It is worth noting that the weight-reducing holes 212 can also be polygonal, such as circular, triangular, quadrilateral or pentagonal. Here, the shape of the weight-reducing holes 212 is not specifically limited.

[0051] In this embodiment, to achieve a detachable connection between the bracket 1 and the tray 2, the bracket 1 and the tray 2 are magnetically fixed. Magnetic fixing is convenient for assembly and disassembly; the two components can quickly and automatically adhere and position themselves when docked, without the need for precise alignment or tools, saving assembly time and manpower. Furthermore, it eliminates mechanical wear, ensuring excellent durability, long service life, and low maintenance costs.

[0052] Furthermore, the mop assembly also includes a first magnetic block 3 and a second magnetic block 4. The hard adhesive layer 21 has multiple first mounting slots 213 spaced apart, each containing a first magnetic block 3. The bracket 1 has multiple second mounting slots 11 spaced apart from the corresponding positions of the first mounting slots 213, each containing a second magnetic block 4. The first magnetic blocks 3 and second magnetic blocks 4 are magnetically connected. The multiple sets of spaced first magnetic blocks 3 and second magnetic blocks 4 further optimize the magnetic fixation effect. This layout makes the magnetic force distribution more uniform and concentrated at key connection points, enhancing the adsorption stability between the bracket 1 and the mop 2, and effectively preventing localized loosening due to uneven magnetic force during vigorous sweeping operation.

[0053] In other embodiments, the bracket 1 and the tray 2 can be fixed with screws, which can also make the bracket 1 and the tray 2 a stable and reliable connection.

[0054] In this embodiment, as Figure 1 As shown, the bracket 1 has a receiving groove 12, in which the mop tray 2 is housed. This design facilitates precise positioning of the mop tray 2, allowing for accurate embedding during installation, reducing positional deviations, stabilizing the mop's contact with the ground, and improving cleaning effectiveness. The receiving groove 12 can enclose and protect the mop tray 2, limiting its displacement under external force, and enhancing the structural reliability and durability of the mop assembly. When the mop tray 2 is placed in the receiving groove 12 after being wrapped with the mop cloth, the space limitation of the receiving groove 12 ensures that the mop cloth and the mop tray 2 are tightly fixed together, further preventing the mop cloth from wrinkling, slipping, or falling off during use, making the fixation between the three more secure and ensuring the continuous effectiveness of the cleaning operation.

[0055] In this embodiment, as Figure 1 and Figure 5 As shown, to achieve a detachable connection between the bracket 1 and the housing, a connecting rod 13 protrudes from the side of the bracket 1 away from the tray 2. A snap-fit ​​protrusion 131 is provided around the connecting rod 13. The connecting rod 13 is inserted into the housing, and the snap-fit ​​protrusion 131 engages with the housing. This snap-fit ​​installation is convenient; simply insert and connect, requiring no complicated steps or tools.

[0056] Specifically, such as Figure 4 and Figure 5 As shown, two annular connecting rods 13 are provided on the side of the bracket 1 away from the mop tray 2, and three grooves are spaced apart on the sidewall of the connecting rod 13 along its length. During the insertion of the connecting rod 13 into the housing, the grooves provide radial elasticity, allowing the connecting rod 13 to be smoothly inserted into the housing. After insertion, the locking protrusion 131 securely engages with the housing, ensuring the stability and reliability of the connection. Specifically, after the bracket 1 and housing are installed, frequent disassembly is not required during daily operation. When the mop needs to be replaced, only the mop tray 2 needs to be removed. Furthermore, as... Figure 4 As shown, to facilitate the disassembly of the mop assembly and the housing, the bracket 1 is provided with a second hand groove 15. When disassembling the mop assembly, the user inserts his / her fingers into the second hand groove 15 and applies force to pry the bracket 1, gradually causing the snap-fit ​​protrusion 131 on the connecting rod 13 to disengage from the snap-fit ​​connection with the housing.

[0057] Furthermore, such as Figure 4 As shown, a first hand groove 14 is provided on the opposite side of the bracket 1 and the second hand groove 15. The arc-shaped notch of the bracket 1 forms the first hand groove 14, which facilitates the disassembly of the tray 2 from the bracket 1. The user only needs to place their fingers in the first hand groove 14 and gently pull outward to overcome the magnetic attraction with the help of the user's hand, allowing the tray 2 to slowly detach from the receiving groove 12 of the bracket 1. During the entire process, due to the presence of the first hand groove 14, the point of application and direction of force can be effectively controlled, avoiding deformation or damage to the tray 2 or the bracket 1 due to uneven force application.

[0058] In this embodiment, as Figure 1 and Figure 8 As shown, a roller 16 is also provided on the side of the bracket 1 connected to the mop 2. When the mop assembly moves with the sweeper, the roller 16 can play a good auxiliary support and rolling role between the ground and the bracket 1, effectively reducing the frictional resistance between the bracket 1 and the ground, making the sweeper push the mop assembly more easily and smoothly.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
