[0007] A cleaning module includes a mobile body, a lifting mechanism, and a cleaning mechanism. The mobile body is mounted on the guide body and moves and cooperates with the guide body along the extension direction of the guide body so as to be able to separate from the guide body. The lifting mechanism is mounted on the mobile body and is connected to the cleaning mechanism in a transmission manner.

[0008] A locking element is used to lock the movable body and the guide body in a locking engagement.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the guide body is provided with a guide portion that moves and cooperates with the movable body. One end of the guide portion extends to one side of the guide body, and a limiting portion is provided at the other end of the guide portion. The limiting portion is used to limit and cooperate with the movable body.

[0011] In one embodiment, the guide body further includes a plurality of rolling elements, each of which is spaced apart on the guide portion along the extending direction of the guide portion and is used to roll in cooperation with the moving body.

[0012] In one embodiment, the guide body is provided with a first positioning structure, and the movable body is provided with a second positioning structure. The first positioning structure is configured to cooperate with the second positioning structure when the movable body is mounted on the guide body.

[0013] In one embodiment, the first positioning structure includes a first positioning part, and the second positioning structure includes a second positioning part that positions and cooperates with the first positioning part. The first positioning part and the second positioning part are respectively disposed on the side of the moving body and the limiting part that are close to each other.

[0014] In one embodiment, there are two guide bodies, which are spaced apart. The movable body is located between the two guide bodies, and the opposite sides of the movable body move and cooperate with the two guide bodies respectively.

[0015] In one embodiment, each of the two guide bodies is provided with a guide portion that moves and cooperates with the movable body on one side of the two guide bodies that are close to each other. The two guide bodies and the two guide portions cooperate to form an insertion space. The movable body and the insertion space are gap-fitted in the spacing direction of the two guide bodies.

[0016] In one embodiment, along the extending direction of the guide body, the moving body is provided with fixing parts on both sides of the end away from the guide body, the two fixing parts are correspondingly provided with the two guide bodies, and the number of locking members is two, the two locking members respectively lock the two fixing parts and the two guide bodies in corresponding locking engagement.

[0017] The fixing part and the guide body are respectively provided on the side of the fixing part that is close to each other, and the third positioning part is used to position and cooperate with the fourth positioning part.

[0018] In one embodiment, the guide body is provided with a V-shaped guide groove, and the movable body includes an upper mounting shaft and a lower mounting shaft; the upper mounting shaft is used to engage with the V-shaped guide groove and move along the extension direction of the V-shaped guide groove until the upper mounting shaft is installed at a preset position on the guide body, and the lower mounting shaft is used to contact the guide body.

[0019] On the other hand, a cleaning device is provided, including a chassis and the cleaning apparatus, wherein the guide body is mounted on the bottom of the chassis.

[0035] 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.

[0036] like Figure 1 and Figure 2As shown, in one embodiment, a cleaning device 10 is provided, including a guide body 110, a cleaning module 200, and a locking member 310. The cleaning module 200 includes a movable body 210, a lifting mechanism 220, and a cleaning mechanism 230. The movable body 210 is mounted on the guide body 110 and is movablely engaged with the guide body 110 along its extension direction to allow for separation from the guide body 110. The lifting mechanism 220 is mounted on the movable body 210 and is kinetically connected to the cleaning mechanism 230. The locking member 310 is used to lock the movable body 210 to the guide body 110.

[0037] In the cleaning device 10 described above, the guide body 110 is pre-installed on the bottom of the cleaning equipment during use. When the cleaning module 200 needs to be installed, the movable body 210 is connected to the guide body 110, and the movable body 210 is driven to move along the extension direction of the guide body 110, so that the movable body 210 is installed in a preset position on the guide body 110. Then, the locking member 310 locks the movable body 210 and the guide body 110 together. When the cleaning module 200 needs to be disassembled, the locking member 310 is disassembled to release the locking engagement between the movable body 210 and the guide body 110. Then, the movable body 210 is driven in the opposite direction to move along the extension direction of the guide body 110, so that the cleaning module 200 leaves the preset position and is pulled out from one side of the bottom of the chassis 20, realizing the separation of the cleaning module 200 from the guide body 110. The cleaning module 200 can be maintained independently without changing the posture of the cleaning equipment, improving the safety and convenience of maintaining the cleaning device 10. In addition, the lifting mechanism 220 can control the lifting of the cleaning mechanism 230 to adjust the ground pressure of the cleaning mechanism 230, ensure the cleaning effect of the cleaning mechanism 230, and improve the reliability of the cleaning device 10.

[0038] The lifting mechanism 220 can be configured as any existing lifting structure. The cleaning mechanism 230 can be configured as any existing cleaning structure.

[0039] It should be noted that the number of cleaning modules 200 can be at least two. The movable bodies 210 in each cleaning module 200 have the same structural dimensions, but the cleaning mechanisms 230 in each cleaning module 200 have different structural types. The different cleaning mechanisms 230 are respectively installed on the movable bodies 210 via the respective lifting mechanisms 220. Thus, by replacing different movable bodies 210, different cleaning mechanisms 230 can be installed on the guide body 110, improving the versatility of the cleaning device 10.

[0040] It should be noted that the mobile body 210 can be initially connected to the guide body 110 by plugging, hooking or other means.

[0041] like Figure 2 and Figure 3 As shown, specifically in this embodiment, the cleaning equipment includes a chassis 20. The guide body 110 can be installed on the bottom of the chassis 20 by screwing, snap-fitting, or other fixed connections, and extends along the width direction of the chassis 20. Thus, the cleaning module 200 can be installed and removed from the side of the cleaning equipment.

[0042] In other embodiments, the guide body 110 may also extend along a diagonal direction or along the length of the chassis 20.

[0043] like Figure 4 and Figure 5 As shown, the guide body 110 further includes a guide portion 111 that moves and engages with the movable body 210. One end of the guide portion 111 extends to one side of the guide body 110, and a limiting portion 112 is provided at the other end of the guide portion 111. The limiting portion 112 is used to limit and engage with the movable body 210. In this way, the movable body 210 can be inserted into or pulled out from the end of the guide portion 111 away from the limiting portion 112, and can move quickly and accurately to a preset position through the limiting action of the limiting portion 112, thereby improving the ease of assembly of the cleaning device 10.

[0044] Specifically, in this embodiment, the guide body 110, the guide portion 111, and the limiting portion 112 can be an integral structure. The guide portion 111 extends along a straight line. The cross-sectional shape of the guide portion 111 can be convex or concave. The guide portion 111 can be a V-shaped guide rail, a rectangular guide rail, a dovetail guide rail, or a cylindrical guide rail, etc.

[0045] Optionally, the guide body 110 also includes a plurality of rolling elements. Each rolling element is spaced apart on the guide portion 111 along the extending direction of the guide portion 111 and is used to roll into contact with the movable body 210. In this way, the movable body 210 and the guide portion 111 are rolled into contact through the rolling elements, which reduces the resistance when installing the movable body 210 and improves the ease of assembly of the cleaning device 10.

[0046] The rolling elements can be configured as balls, rollers, needle rollers, or other rolling structures. The number of rolling elements can be flexibly adjusted according to actual usage requirements.

[0047] In one embodiment, the guide body 110 is provided with a first positioning structure, and the movable body 210 is provided with a second positioning structure. The first positioning structure is configured to engage with the second positioning structure when the movable body 210 is mounted on the guide body 110. Thus, the movable body 210 can be positioned on the guide body 110 through the engagement of the first and second positioning structures, ensuring the accurate position of the cleaning module 200 relative to the chassis 20 after installation and improving the reliability of the cleaning device 10.

[0048] It should be noted that the first positioning structure can be directly mounted on the guide body 110 or indirectly mounted on the guide body 110. The second positioning structure can be directly mounted on the moving body 210 or indirectly mounted on the guide body 110.

[0049] like Figure 4 As shown, optionally, the first positioning structure includes a first positioning part 113. The second positioning structure includes a second positioning part 211 that positions and engages with the first positioning part 113. The first positioning part 113 and the second positioning part are respectively disposed on the side where the movable body 210 and the limiting part 112 are close to each other. In this way, while the movable body 210 and the limiting part 112 are in a limiting engagement, the first positioning part 113 and the second positioning part 211 are also correspondingly positioned and engaged, improving the ease of assembly of the cleaning device 10.

[0050] In this specific embodiment, one of the first positioning part 113 and the second positioning part 211 is configured as a positioning post, and the other is configured as a first positioning hole. The free end of the positioning post is chamfered. The chamfer is used to guide the positioning post into the first positioning hole. In this way, the chamfer can play a guiding role, making it easier for the positioning post to enter the first positioning hole.

[0051] like Figure 6 As shown, optionally, the second positioning structure includes a protruding positioning portion 215. Along the extending direction perpendicular to the guide body 110, the moving body 210 has a protruding positioning portion 215 on the side near the guide body 110. The protruding positioning portion 215 is used for positioning and engaging with the guide body 110. Thus, the protruding positioning portion 215 can also achieve the positioning function between the moving body 210 and the guide body 110, and is easy to manufacture.

[0052] Specifically, in this embodiment, the raised positioning part 215 can be configured as a gradient contour of the moving body 210. In other embodiments, the raised positioning part 215 can also be configured as a raised spherical surface or a raised arc surface. The raised positioning part 215 can also be disposed on the guide body 110 and correspondingly positioned and engaged with the moving body 210.

[0053] like Figure 4 and Figure 5As shown, in one embodiment, there are two guide bodies 110. The two guide bodies 110 are spaced apart. A movable body 210 is located between the two guide bodies 110. The opposite sides of the movable body 210 respectively move and engage with the two guide bodies 110. In this way, the movable body 210 can be hung between the two guide bodies 110, thereby reducing the contact area between the movable body 210 and the guide bodies 110, thus reducing the resistance during the installation of the cleaning module 200 and improving the ease of assembly of the cleaning device 10.

[0054] In this specific embodiment, the two guide bodies 110 are symmetrically arranged.

[0055] like Figure 5 As shown, optionally, each of the two guide bodies 110 has a guide portion 111 on one side that is close to each other, which moves and cooperates with the movable body 210. The two guide bodies 110 and the two guide portions 111 cooperate to form an insertion space. The movable body 210 and the insertion space are gap-fitted in the spacing direction of the two guide bodies 110. In this way, a gap is left between the guide body 110 and the movable body 210, so that the guide body 110 can be more easily installed on the guide body 210.

[0056] like Figure 5 As shown, specifically in this embodiment, movable flanges 212 are provided on both opposite sides of the movable body 210. The two movable flanges 212 are symmetrically arranged and respectively move and cooperate with the top surfaces of the two guide portions 111. Along the spacing direction of the two guide bodies 110, the distance between the two movable flanges 212 on the side that is far apart from each other is smaller than the distance between the two guide bodies 110, and the distance between the two guide portions 111 is smaller than the width of the movable body 210.

[0057] like Figure 4 As shown, in one embodiment, along the extending direction of the guide body 110, the movable body 210 has fixing portions 213 on opposite sides of the end away from the guide body 110. Two fixing portions 213 are correspondingly provided with two guide bodies 110. Two locking members 310 are provided. The two locking members 310 respectively lock the two fixing portions 213 to the two guide bodies 110. Thus, when the movable body 210 is installed on the guide body 110, the two locking members 310 lock the two fixing portions 213 to the two guide bodies 110 as a whole, making the movable body 210 and the guide body 110 completely fixed together, improving the reliability of the cleaning device 10.

[0058] like Figure 4As shown, optionally, the first positioning structure includes a third positioning part 114. The second positioning structure includes a fourth positioning part 214. The third positioning part 114 and the fourth positioning part 214 are respectively provided on the side of the fixed part 213 that is close to the guide body 110. The third positioning part 114 is used for positioning and cooperating with the fourth positioning part 214. In this way, the moving body 210 can be initially positioned with the guide body 110 through the third positioning part 114 and the fourth positioning part 214, ensuring accurate positioning of the cleaning module 200 after installation and improving the reliability of the cleaning device 10.

[0059] like Figure 4 As shown, optionally, the locking member 310 can be a locking screw 311. The fixing part 213 is provided with a mounting through hole 216. The guide body 110 is provided with a threaded hole 115 corresponding to the mounting through hole 216. The locking screw 311 passes through the mounting through hole 216 and is threaded into the threaded hole 115. In this way, after unscrewing the locking screw 311, the moving body 210 can be pulled away from the guide body 110, which is simple and convenient to operate and improves the practicality of the cleaning device 10.

[0060] like Figure 7 As shown, in other embodiments, the locking member 310 may also be configured as a latch 312. The latch 312 is rotatably mounted on the guide body 110 and is configured to fasten the fixing part 213 to the guide body 110 when the movable body 210 is mounted on the guide body 110.

[0061] like Figure 8 and Figure 9 As shown, in one embodiment, the guide body 110 is provided with a V-shaped guide groove 116. The movable body 210 includes an upper mounting shaft 217 and a lower mounting shaft 218. The upper mounting shaft 217 is used to engage with the V-shaped guide groove 116 and move along the extending direction of the V-shaped guide groove 116 until the upper mounting shaft 217 is mounted at a preset position on the guide body 110. The lower mounting shaft 218 is used to contact the guide body 110.

[0062] When the cleaning module 200 needs to be installed, firstly, the upper mounting shaft 217 is inserted into the V-shaped guide groove 116. Under the influence of gravity, the upper mounting shaft 217 remains in contact with the inner wall of the V-shaped guide groove 116, while the lower mounting shaft 218 remains in contact with the guide body 110 due to the torque generated by the center of gravity of the cleaning module 200. The cleaning module 200 and the guide body 110 form a stable state. Then, the upper mounting shaft 217 is driven to move along the extension direction of the V-shaped guide groove 116 until it is installed at the preset position on the guide body 110. Finally, the locking member 310 is installed to completely fix the cleaning module 200 onto the guide body 110, completing the assembly of the cleaning device 10.

[0063] like Figure 9 and Figure 10 As shown, optionally, the first positioning structure includes a second positioning hole 117. The second positioning hole 117 is disposed on the guide body 110. The lifting mechanism 220 includes a fixed bracket 221 for connection with the movable body 210. The second positioning structure includes a positioning pin 219. The positioning pin 219 is mounted on the fixed bracket 221 and is correspondingly disposed with the second positioning hole 117. The positioning pin 219 is configured to engage with the second positioning hole 117 when the upper mounting shaft 217 is mounted at a preset position on the guide body 110. Thus, the engagement of the positioning pin 219 with the second positioning hole 117 can also achieve the positioning function, ensuring accurate positioning of the cleaning module 200 after installation and improving the reliability of the cleaning device 10.

[0064] Specifically, in this embodiment, the upper mounting shaft 217 and the lower mounting shaft 218 are mounted on the fixed bracket 221 at intervals. The locking member 310 is used to lock the fixed bracket 221 and the guide body 110 in a locking engagement.

[0065] In one embodiment, a cleaning device is provided, including a chassis 20 and a cleaning device 10 as described in any of the above embodiments. A guide body 110 is mounted on the bottom of the chassis 20. Thus, the cleaning device includes the cleaning device 10 and therefore has the technical effects corresponding to the cleaning device 10, which will not be described in detail here.

[0066] The cleaning equipment can be set as a cleaning robot, a sweeper, or a floor scrubber, etc.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[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 above embodiments merely illustrate 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.
