Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to mop modules and cleaning robots. Background Technology

[0002] With the improvement of living standards, cleaning robots have gradually gained popularity due to their simple operation and ease of use, becoming an important member of small household appliances. Cleaning robots can perform cleaning operations such as sweeping and mopping. When mopping, cleaning robots generally use a tracked mop module to perform the mopping operation.

[0003] When replacing the mop head of a tracked mop module, the mop head needs to be disassembled and installed according to the structural design of different types of tracked mop modules. For ordinary users, the mop head replacement operation is relatively complicated, and they also need to come into contact with the dirt on the mop head, resulting in a poor user experience. Utility Model Content

[0009] The mop body is movably mounted on a plurality of the aforementioned rotating shaft assemblies.

[0010] In one embodiment, the mop module includes:

[0011] A support assembly, wherein the number of the support assemblies is configured to be at least two, and the plurality of the support assemblies are respectively movably assembled in the plurality of the assembly areas, and the support assemblies are configured to make stress contact with the rotating shaft assembly;

[0012] The fixed bracket is further provided with a second limiting part. The first limiting part is configured to limit contact with the rotating shaft assembly along a first direction, and the second limiting part is configured to limit contact with the support assembly along a second direction, thereby restricting the rotating shaft assembly from disengaging from the assembly area by the first limiting part and the second limiting part.

[0015] In one embodiment, the first limiting portion is configured to have a limiting hole in the fixed bracket, the limiting hole being configured to allow the shaft end of the rotating shaft assembly to pass through, thereby restricting the movement of the rotating shaft assembly in a direction away from the main bracket; and / or,

[0016] The second limiting portion is configured as a limiting protrusion on the fixed bracket, the limiting protrusion being configured to support the support assembly in a direction away from the fixed bracket, thereby indirectly restricting the movement of the rotating shaft assembly in a direction close to the main bracket through the support assembly.

[0018] The rotating shaft assembly is movably assembled in several support cavities of the matching assembly area, and the support element is in stress contact with the rotating shaft assembly.

[0019] In one embodiment, the limiting protrusion has a first guide ramp, and the support element has a second guide ramp. The first guide ramp of the limiting protrusion is configured to guide into contact with the second guide ramp of the mating support element, thereby indirectly limiting the movement of the mating shaft assembly along a direction close to the main support via the support element; and / or,

[0020] The fixed bracket includes an end frame and a limiting frame connected together, with the first limiting part disposed on the end frame and the second limiting part disposed on the limiting frame.

[0021] In one embodiment, the main support has at least two linear cavities, each of which communicates with a plurality of support cavities of a matching assembly area, and the limiting frame is configured as a linear post, each of which is configured to pass through a matching linear cavity.

[0029] As can be seen from the above-mentioned mop module and cleaning robot, the mop module in the above structural design only has four types of components: main support, rotating shaft assembly, fixed support, and mop body. The main support serves as the assembly base for the rotating shaft assembly, fixed support, and mop body. The mop body can rotate relative to the main support based on several rotating shaft assemblies, cleaning the floor by rotating the mop body during the cleaning process. The fixed support uses a first limiting part to prevent the rotating shaft assembly from detaching from the assembly area of ​​the main support, allowing each rotating shaft assembly to be more stably assembled to the main support. Although the structure is simplified, it ensures the functionality of the entire mop module and reduces manufacturing costs. Compared to the existing complex module structures, the mop module of this application can be used as a disposable module, improving the user experience. Attached Figure Description

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] This application provides a cleaning robot, comprising a cleaning main unit and a mop module, the mop module being detachably mounted to the cleaning main unit. Given that existing mop modules require users to manually remove the used mop after completing a cleaning task and install a new, unused mop, this process is not only cumbersome but also involves touching the dirty mop. Therefore, the mop module provided in this application is designed as a disposable module, allowing the entire used mop module to be removed and replaced with a new, unused mop after completing a cleaning task. This simplifies the operation and eliminates the need for separate contact with and removal of the dirty mop, thereby improving the user experience.

[0049] When the mop module of this application is designed as a disposable replacement module, the focus is on reducing the cost of the mop module, making the cleaning task affordable for users. Therefore, the mop module provided by this application mainly improves upon structural and material design, thereby effectively reducing manufacturing costs without affecting the user experience.

[0050] For the structural design of the mop module in this application, please refer to [reference needed]. Figure 1 and Figure 2 As shown, the mop module may include a main support 1000, a rotating shaft assembly 2000, a fixed support 3000, and a mop body 4000. The main support 1000 serves as the assembly base for the rotating shaft assembly 2000, the fixed support 3000, and the mop body 4000. The main support 1000 can be designed with various suitable structures, shapes, and sizes according to assembly requirements, thereby satisfying the assembly of the rotating shaft assembly 2000, the fixed support 3000, and the mop body 4000, and realizing the function of any one of the rotating shaft assembly 2000, the fixed support 3000, and the mop body 4000, without any limitation here.

[0051] See Figure 3As shown, the main support 1000 may initially be provided with at least two assembly areas 1001. Each assembly area 1001 is defined as a specific region on the main support 1000. This assembly area 1001 can be used to mount the pivot assembly 2000. Therefore, the design can be based on the structure, shape, and size of the pivot assembly 2000. The number of pivot assemblies 2000 can be configured to be at least two, with several pivot assemblies 2000 rotatably mounted in several assembly areas 1001. For example, see [reference needed]. Figure 3 and Figure 4 As shown, the main support 1000 can be provided with two assembly areas 1001, so that each of the two rotating shaft assemblies 2000 can be assembled into a matching assembly area 1001 provided in the main support 1000.

[0052] Continue reading Figure 3 and Figure 4 As shown, the number of fixed brackets 3000 can also be configured to be at least two. A plurality of fixed brackets 3000 are assembled on the main body bracket 1000, and the plurality of fixed brackets 3000 are configured to limit the engagement with a plurality of rotating shaft assemblies 2000. The number of fixed brackets 3000 matches the number of rotating shaft assemblies 2000. For example, when there are two assembly areas 1001 and two rotating shaft assemblies 2000, the number of fixed brackets 3000 can also be configured to be two. This allows each of the two fixed brackets 3000 to limit the engagement with a matching rotating shaft assembly 2000 in the main body bracket 1000. Thus, one fixed bracket 3000 is used to restrict one rotating shaft assembly 2000 from detaching from the main body bracket 1000, so that each rotating shaft assembly 2000 can be more stably assembled on the main body bracket 1000.

[0053] Regarding the limiting engagement between the fixed brackets 3000 and the rotating shaft assemblies 2000, the fixed brackets 3000 may be provided with a first limiting part 3010. The first limiting part 3010 may be configured to make limiting contact with the rotating shaft assembly 2000, thereby limiting the rotating shaft assembly 2000 from disengaging from the assembly area 1001 of the main bracket 1000, so that each rotating shaft assembly 2000 can be more stably assembled with the main bracket 1000. Therefore, when the mop body 4000 is movably sleeved on the rotating shaft assemblies 2000, the mop body 4000 can rotate relative to the main bracket 1000 based on the rotating shaft assemblies 2000, and the floor is cleaned by rotating the mop body 4000 during the cleaning process. In addition, those skilled in the art can also choose other limiting methods or limiting structures to achieve stable assembly of the rotating shaft assembly 2000 relative to the main bracket 1000 according to actual needs, which is not limited here.

[0054] Therefore, in the above structural design of the mop module, the mop module only has four types of components: the main support 1000, the rotating shaft assembly 2000, the fixed support 3000, and the mop body 4000. The main support 1000 serves as the assembly base for the rotating shaft assembly 2000, the fixed support 3000, and the mop body 4000. The mop body 4000 can rotate relative to the main support 1000 based on several rotating shaft assemblies 2000, cleaning the floor by rotating the mop body 4000 during the cleaning process. The fixed support 3000 uses its first limiting part 3010 to restrict the rotating shaft assembly 2000 from disengaging from the assembly area 1001 of the main support 1000, allowing each rotating shaft assembly 2000 to be more stably assembled to the main support 1000. Although the structure is simplified, it ensures the functionality of the entire mop module and reduces manufacturing costs. Compared to existing complex module structures, the cost of the mop module in this application is comparable to that of a disposable module, thus improving the user experience.

[0055] Continue reading Figure 2 and Figure 3 As shown, in one embodiment, the mop module may further include support components 5000. The number of support components 5000 is configured to be at least two, with several support components 5000 movably assembled in several assembly areas 1001. The support components 5000 are configured for stress contact with the rotating shaft assembly 2000. The number of support components 5000 matches the number of rotating shaft assemblies 2000. For example, when there are two assembly areas 1001 and two rotating shaft assemblies 2000, the number of support components 5000 can also be configured to be two. This allows each of the two support components 5000 to have stress contact with a matching rotating shaft assembly 2000 in the main support 1000, thereby supporting one rotating shaft assembly 2000 with one support component 5000. The support components 5000 may adopt regular or irregular support structures such as support bars, support sheets, or support blocks; no limitation is made here.

[0056] In response, the fixed bracket 3000 is also provided with a second limiting part 3020. If the first limiting part 3010 is configured to limit contact with the rotating shaft assembly 2000 along the first direction, the second limiting part 3020 can be configured to limit contact with the support assembly 5000 along the second direction. The first direction and the second direction are different directions, for example, the first direction and the second direction can be designed to be opposite directions. Therefore, when the first limiting part 3010 limits contact with the rotating shaft assembly 2000, it can apply a force in the first direction to the rotating shaft assembly 2000. When the second limiting part 3020 limits contact with the support assembly 5000, it can apply a force in the second direction to the support assembly 5000. In turn, the support assembly 5000 indirectly applies a force in the second direction to the rotating shaft assembly 2000 again.

[0057] Because the first and second directions are different, or even completely opposite, the combined force applied to the pivot assembly 2000 in the first and second directions creates a mutually restrictive fit, thereby firmly fixing the pivot assembly 2000 to a specific position on the main support 1000, namely the assembly area 1001 of the main support 1000, ensuring the secure and stable assembly of the pivot assembly 2000 on the main support 1000. Based on the above method, the restrictive force jointly applied by the first limiting part 3010 and the second limiting part 3020 can prevent the pivot assembly 2000 from detaching from the assembly area 1001, ensuring that each pivot assembly 2000 can be more stably assembled on the main support 1000.

[0058] For further information on the first and second directions mentioned above, please refer to [link / reference]. Figure 5 and Figure 6 As shown, in one embodiment, the first limiting portion 3010 is configured to restrict the rotation shaft assembly 2000 from moving in a direction away from the main support 1000, i.e., to prevent the rotation shaft assembly 2000 from moving along... Figure 5 and Figure 6 The movement is in direction a, as shown. The second limiting portion 3020 is configured to restrict the support assembly 5000 from moving in the direction close to the main support 1000, i.e., to prevent the rotating shaft assembly 2000 from moving along... Figure 5 and Figure 6 The movement in direction b, as shown, indirectly restricts the movement of the pivot assembly 2000 along the direction close to the main support 1000 via the support component 5000. Therefore, directions a and b are opposite, and the forces acting in directions a and b create a mutually restrictive fit, firmly limiting and fixing the pivot assembly 2000 to a specific position on the main support 1000, namely the assembly area 1001 of the main support 1000, ensuring the secure and stable assembly of the pivot assembly 2000 on the main support 1000. It should be noted that, due to... Figure 5 and Figure 6 The device has two rotating shaft assemblies 2000 and a fixed bracket 3000 arranged opposite to each other. Therefore, directions a and b indicate the directions in which the two rotating shaft assemblies 2000 are away from or close to the bracket body, respectively.

[0059] The first limiting part 3010 can be implemented using structures such as protrusions, grooves, or through holes. For example, in one embodiment, the first limiting part 3010 is configured to have a limiting hole in the fixed bracket 3000. The limiting hole is configured to allow the shaft end of the rotating shaft assembly 2000 to pass through. When the shaft end of the rotating shaft assembly 2000 passes through the limiting hole, the rotating shaft assembly 2000 can rotate relative to the limiting hole on a fixed axis, and the limiting hole can also rotate in the diameter direction (e.g., ...). Figure 5 and Figure 6 (a) restricts the movement of the rotating shaft assembly 2000 relative to the main support 1000, that is, restricts the movement of the rotating shaft assembly 2000 in a direction away from the main support 1000.

[0060] The second limiting part 3020 can be implemented using structures such as protrusions, grooves, or through holes. For example, the second limiting part 3020 is configured as a limiting protrusion provided on the fixed bracket 3000. The limiting protrusion is configured to support the support assembly 5000 in a direction away from the fixed bracket 3000. When the support assembly 5000 and the rotating shaft assembly 2000 are simultaneously assembled in the assembly area 1001 of the main bracket 1000, the rotating shaft assembly 2000 can be indirectly and movably assembled in the assembly area 1001 through the support assembly 5000. At this time, the limiting protrusion can make stress contact with the support assembly 5000. Figure 5 and Figure 6 The b-direction restricts the movement of the support assembly 5000 relative to the main support 1000, thereby indirectly restricting the movement of the pivot assembly 2000 in the direction close to the main support 1000.

[0061] Continue reading Figure 2 As shown, in one embodiment, each assembly area 1001 of the main support 1000 has a plurality of support cavities 1100, and each support assembly 5000 includes a plurality of support elements 5100. The plurality of support elements 5100 are movably assembled in the plurality of support cavities 1100. For example, one support element 5100 can be provided in each support cavity 1100. The plurality of support elements 5100 in the same assembly area 1001 can be identified as a support assembly 5000. The plurality of support elements 5100 in a support assembly 5000 can be independent elements or interconnected elements, which is not limited here.

[0062] Therefore, each pivot assembly 2000 can be movably assembled in a matching assembly area 1001, and in the matching assembly area 1001, each pivot assembly 2000 can be simultaneously assembled in a plurality of support cavities 1100, and each pivot assembly 2000 can simultaneously be in stress contact with a plurality of support elements 5100 in a support assembly 5000. For example, in the matching assembly area 1001, each pivot assembly 2000 can be simultaneously assembled in two or three support cavities 1100, and each pivot assembly 2000 can simultaneously be in stress contact with two or three support elements 5100 in a support assembly 5000.

[0063] Continue reading Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, the limiting protrusion has a first guide slope 3021 and the support element 5100 has a second guide slope 3022. The first guide slope 3021 of the limiting protrusion is configured to guide into contact with the second guide slope 3022 of the matching support element 5100, thereby indirectly limiting the movement of the matching pivot assembly 2000 along a direction close to the main support 1000 via the support element 5100.

[0064] Therefore, as Figure 5 As shown, when the first guide slope 3021 of the limiting protrusion and the second guide slope 3022 of the support element 5100 are not in guiding contact, the shaft assembly 2000 and several support elements 5100 of the support assembly 5000 are in a relatively loose state in the support cavity 1100. The shaft assembly 2000 is not in a fully assembled state in the main support 1000, and the mop body 4000 is also in a loose state with respect to the shaft assembly 2000. In this state, the mop body 4000 cannot rotate stably relative to the shaft assembly 2000. At this time, the shaft assembly 2000 is relatively close to the main support 1000 in the directions shown in a and b.

[0065] However, as Figure 6As shown, when the first guide slope 3021 of the limiting protrusion contacts the second guide slope 3022 of the support element 5100, the shaft assembly 2000 and several support elements 5100 of the support assembly 5000 form stress contact in the support cavity 1100, supporting and cooperating with each other. Both the shaft assembly 2000 and several support elements 5100 of the support assembly 5000 are in a relatively compact assembly state in the support cavity 1100. The shaft assembly 2000 is in an assembled state in the main support 1000, allowing the shaft end of the shaft assembly 2000 to align with the first limiting part 3010. The mop body 4000 and the shaft assembly 2000 are also in a taut support state. In this state, the mop body 4000 can rotate stably relative to the shaft assembly 2000.

[0066] Continue reading Figure 2 , Figure 5 and Figure 6 As shown, the fixing bracket 3000 may include a connected end bracket 3100 and a limiting bracket 3200. A first limiting part 3010 is disposed on the end bracket 3100, and a second limiting part 3020 is disposed on the limiting bracket 3200. At this time, the fixing bracket 3000 is in the position as shown... Figure 5 and Figure 6 As shown, it can be assembled relative to the main support 1000 in the left and right directions, as in... Figure 5 The state shown is as follows Figure 6 When the assembly state changes as shown, the fixed bracket 3000 can be moved to the right, so that the first guide slope 3021 of the limiting protrusion makes guiding contact with the second guide slope 3022 of the support element 5100. This forces the rotating shaft assemblies 2000 on both sides to move away from the main bracket 1000 (i.e., in direction a) under the supporting force of the support assembly 5000. This allows the shaft ends of both rotating shaft assemblies 2000 to align with the first limiting part 3010 and then pass through the limiting hole, thus changing to the position shown. Figure 6 The assembly state is shown.

[0067] In one embodiment, the main support 1000 has at least two linear cavities 1200, each linear cavity 1200 communicating with a plurality of support cavities 1100 of a matching assembly area 1001. A limiting frame 3200 is configured as a linear post, each linear post configured to pass through a matching linear cavity 1200. Therefore, when the fixed support 3000 is moved to the right, the limiting frame 3200 can move to the right along the linear cavity 1200, causing the first guide slope 3021 of the limiting protrusion to make guiding contact with the second guide slope 3022 of the support element 5100. This forces the rotating shaft assemblies 2000 on both sides to move away from the main support 1000 (i.e., direction a) under the supporting force of the support assembly 5000, thereby enabling the shaft ends of both rotating shaft assemblies 2000 to align with the first limiting portion 3010 and then pass through the limiting hole, thus transforming into... Figure 6 The assembly state is shown.

[0068] In one embodiment, the pivot assembly 2000 may include a central shaft 2100 and at least one pivot sleeve 2200 movably fitted onto the central shaft 2100. For example, the central shaft 2100 may be fitted with two or three pivot sleeves 2200. For the portion of the central shaft 2100 not covered by the pivot sleeves 2200, the support assembly 5000 may be configured to make stress contact with the central shaft 2100. This ensures that the stress contact between the support assembly 5000 and the central shaft 2100 does not affect the rotation of the pivot sleeves 2200, thereby allowing the mop body 4000 to be movably fitted onto the pivot sleeves 2200 of the pivot assembly 2000, enabling the mop body 4000 to rotate relative to the main support 1000 via the pivot sleeves 2200. Furthermore, the main support 1000 has a weight-reducing through hole 1300.

[0069] In one embodiment, the main support 1000, fixed support 3000, support assembly 5000, and rotating bushing 2200 are made of resin. The central shaft 2100 is made of metal. Due to the high strength and high stability of the mop module, the material requirements for each component are relatively low. Except for the central shaft 2100, which requires an embedded metal shaft, the rest of the structure can be made of commonly used resin materials, which have high machinability and very low overall cost.

[0070] In summary, the mop module provided in this application adopts an integrated frame design, which offers high stability, convenient assembly, and low cost. The mop module has few parts, and the assembly of each component is simple. Most of the structure in the mop module is injection molded, requiring minimal additional processing. Specifically, the main support 1000 is a one-piece injection molded part, exhibiting high overall strength and minimal deformation. After assembly into a module, the parallelism between the various rotating shaft components 2000 is high, resulting in more stable operation.

[0071] Simultaneously, this design ensures that the spacing between the squeegee groove and corresponding points within the mop body 4000 remains consistent, guaranteeing a stable moisture content in the mop body 4000 while the mop module operates on the cleaning robot. This high stability also minimizes the axial force on the mop body 4000, effectively preventing it from veering off course and resolving issues such as bulging and tearing. Furthermore, it increases the mop module's tolerance to errors in the mop body 4000, eliminating the need for inspection processes related to the size of the ends during mop body 4000 manufacturing, thus reducing production costs by approximately 25%.

[0072] Since the mop module is a single unit, it is inexpensive and can be replaced when it reaches the end of its service life. This eliminates the need to replace the mop itself, reducing complicated operations and eliminating the need for users to manually handle dirt on the mop body 4000, thus improving the user experience.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
