[0093] In the embodiment of the present application, the lifting mechanism is arranged to connect the cleaning module 1 and the device main body, so as to adjust the distance between the cleaning module 1 and the ground, and facilitate the use of the cleaning device 100.

[0094] Please refer to Figures 6-9 , Figure 6 The structural schematic diagram of the cleaning module 1 provided in the embodiment of the present application is shown in the figure. Figure 7 The structural schematic diagram of the cleaning module 1 provided in the embodiment of the present application is shown in the figure. Figure 8 The structural schematic diagram of the cleaning module 1 provided in the embodiment of the present application is shown in the figure. Figure 9 The structural schematic diagram of the cleaning module 1 provided in the embodiment of the present application is shown in the figure.

[0095] In one embodiment, please refer to Figure 6 and Figure 7 The cleaning module 1 comprises a support 11, a water absorption structure 12 and a wiping assembly 13, and the water absorption structure 12 and the wiping assembly 13 are arranged on the support 11.

[0096] In one example, the water absorption structure 12 is a water absorption scraping strip. Please refer to Figure 7 and Figure 8 The water absorption structure 12 is shown in the figure, please refer to Figure 8 A water absorption cavity 121 is arranged at the bottom of the water absorption structure 12 (the bottom of the water absorption structure 12 refers to the side of the water absorption structure 12 facing the ground when the cleaning device 100 is supported on the ground). The water absorption structure 12 is connected with a sewage tank on the cleaning device 100, and the sewage tank is connected with a negative pressure generating assembly. When the negative pressure generating assembly works, the sewage tank and the water absorption cavity 121 of the water absorption structure 12 can generate negative pressure to absorb the sewage on the ground.

[0099] Please refer to Figure 7 The wiping assembly 13 arranged on the support 11 is shown in the figure, and the wiping assembly 13 is used to wipe the water stains left on the ground by the water absorption structure 12.

[0100] It can be understood that when the water absorption structure 12 of the cleaning device 100 performs the sewage absorption operation on the ground, the area of the ground on which the water absorption structure 12 has completed the sewage absorption operation is referred to as a sewage absorption completed area. For the sewage absorption completed area, there can still be water stains on the ground (for example, sewage is missed at the joint of the ground). The wiping assembly 13 can perform the wiping operation on the sewage absorption completed area in a timely manner, so as to reduce or even avoid the situation that water stains are left on the ground, thereby improving the ground cleaning capability of the cleaning module 1.

[0101] In the embodiment of the present application, the wiping assembly 13 is arranged on the support 11 to perform the wiping operation on the area of the water absorption structure 12 in a timely manner, so as to reduce or even avoid the situation that water stains are left on the ground, thereby improving the ground cleaning capability of the cleaning module 1.

[0102] In an embodiment, as shown in Figure 7 and Figure 8 , the cleaning module 1 further comprises a wet mopping component 14, which is arranged on the support 11 and located at the front side of the water absorption structure 12 along the cleaning direction of the cleaning module 1.

[0103] Along the cleaning direction of the cleaning module 1, it can be understood as the forward movement direction of the cleaning device 100 on the ground. When the cleaning module 1 cleans the ground, the same area on the ground is first wet mopped by the wet mopping component 14 and then the sewage on the ground is absorbed and recycled by the water absorption structure 12.

[0104] In an example, the wet mopping component 14 cooperates with the clean water tank of the cleaning device 100, that is, the clean water tank can provide clean water to the wet mopping component 14 to wet the wet mopping component 14.

[0105] In an example, the material of the wet mopping component 14 is cotton cloth, sponge, fiber cloth or the like, so as to facilitate wiping the ground.

[0106] In an example, as shown in Figure 7 , the shape of the side of the wet mopping component 14 close to the water absorption structure 12 matches the shape of the water absorption structure 12, both of which are arc-shaped, so as to facilitate increasing the area of the wet mopping component 14.

[0107] In the embodiment of the present application, by arranging that the cleaning module 1 further comprises the wet mopping component 14, the wet mopping operation on the ground can be realized, thereby improving the ground cleaning capability of the cleaning module 1.

[0108] In an embodiment, as shown in Figures 6-8 , the support 11 further comprises a corner cleaning assembly 16, which is close to one end of the support 11. The corner cleaning assembly 16 is used to clean the corners on the ground.

[0109] As shown in Figure 9The corner cleaning assembly 16 comprises a corner cleaning element 161. In one example, the corner cleaning element 161 is a corner mop. In other examples, the corner cleaning element 161 is a corner brush.

Please refer to Figure 9 The corner driving motor 162 is connected to the corner cleaning element 161 through the corner transmission mechanism. The corner driving motor 162 and the corner transmission mechanism are supported on the support 11. When the corner driving motor 162 is actuated, the corner cleaning element 161 can be driven to rotate through the corner transmission mechanism, so as to clean the corner of the ground.

[0111] In one example, please refer to Figure 9 The corner cleaning assembly 16 further comprises a corner protective shell 163. The corner protective shell 163 is supported on the support 11, and the corner transmission mechanism is arranged in the corner protective shell 163.

[0112] In one example, the corner transmission mechanism is a gear transmission mechanism, which is beneficial to precise transmission.

[0113] In the embodiment, the corner cleaning assembly 16 is further arranged on the support 11, so as to clean the corner of the ground through the corner cleaning assembly 16.

[0114] Please refer to Figure 10 , Figure 10 The top view of the cleaning module 1 provided in the embodiment is shown.

[0115] In one example, please refer to Figure 10 The drying assembly 13 comprises a plurality of drying units 131, and each drying unit 131 is supported on the support 11. That is, the drying assembly 13 can be understood as a structure comprising a plurality of components. In other examples, the drying assembly 13 is a structure comprising only one component. Hereinafter, the drying assembly 13 will be described mainly by taking the example that the drying assembly 13 comprises a plurality of drying units 131.

[0116] In one example, the drying unit 131 is rotatably connected to the support 11, so as to better clean the ground. In other examples, the drying unit 131 is fixed on the support 11, so as to simplify the structure of the cleaning module 1.

[0117] In one example, the part (i.e., the connecting part 1313 hereinafter) of the drying unit 131 for wiping the ground is circular or elliptical or strip-shaped, etc.

[0118] In the embodiment, the drying assembly 13 comprises a plurality of drying units 131, so as to arrange the drying units 131 on the frame body according to the shape of the support 11.

[0119] In an embodiment, along the cleaning direction of the cleaning module 1, the plurality of drying units 131 are arranged at the rear side of the water absorption structure 12 and are sequentially distributed along the direction parallel to the length extension direction of the water absorption structure 12. In the embodiment, the drying units 131 arranged at the rear side of the water absorption structure 12 are referred to as rear-side drying units 1311. Please refer to Figure 10 , which shows the rear-side drying units 1311.

[0120] As described above, along the cleaning direction of the cleaning module 1, it can be understood as the forward travel direction of the cleaning device 100 on the ground. That is, when the cleaning module 1 cleans the ground, the same area on the ground is first subjected to the adsorption and recovery of the water on the ground by the water absorption structure 12, and then subjected to the drying operation of the water stains on the ground by the rear-side drying units 1311.

[0121] In an example, the number of rear-side drying units 1311 is two or three or four or five or six, etc. Please refer to Figure 10 , which shows five rear-side drying units 1311. The number of rear-side drying units 1311 can be reasonably set according to the size of the cleaning module 1.

[0122] Please refer to Figure 10 , which shows that the water absorption structure 12 is in the shape of a circular arc, and the rear-side drying units 1311 are sequentially distributed along the direction parallel to the length extension direction of the water absorption structure 12, that is, the rear-side drying units 1311 are also in the shape of a circular arc, so as to facilitate reducing the area of the support 11 and further reducing the volume of the cleaning module 1.

[0123] In an example, the two adjacent rear-side drying units 1311 are in contact; in other examples, there is a gap between the two adjacent rear-side drying units 1311.

[0124] In an example, please refer to Figure 10 , the opposite ends of the water absorption structure 12 are respectively a left end 123 of the scraping strip and a right end 124 of the scraping strip, the rear-side drying unit 1311 close to the left end 123 of the scraping strip in each rear-side drying unit 1311 is a leftward rear-side drying unit, and the rear-side drying unit 1311 close to the right end 124 of the scraping strip in each rear-side drying unit 1311 is a rightward rear-side drying unit. Please refer to Figure 10 , which shows the tangent L1 of the leftward rear-side drying unit and the tangent L2 of the rightward rear-side drying unit, wherein the distance between the tangent L1 and the tangent L2 is greater than the distance between the left end 123 of the scraping strip and the right end 124 of the scraping strip. The leftward rear-side drying unit protrudes to the left of the left end 123 of the scraping strip, and the rightward rear-side drying unit protrudes to the right of the right end 124 of the scraping strip.

[0125] In an example, the range of the value of the distance D1 between the tangent line L1 and the left end 123 of the blade is 1mm-10mm; the range of the value of the distance D2 between the tangent line L2 and the right end 124 of the blade is 1mm-10mm.

[0126] In the embodiment of the present application, the plurality of drying units 131 are arranged on the rear side of the water absorption structure 12 to timely perform the drying operation on the area on the rear side of the water absorption structure 12.

[0127] In an embodiment, at least one drying unit 131 is arranged close to the end of the corresponding side of the water absorption structure 12. In the embodiment, the drying unit 131 close to the end of the water absorption structure 12 is referred to as an end drying unit 1312. Please refer to Figure 10 , which shows two end drying units 1312, which are respectively close to the left end 123 and the right end 124 of the blade of the water absorption structure 12.

[0128] In an example, there is only the end drying unit 1312 close to the left end 123 of the blade; in other examples, there is only the end drying unit 1312 close to the right end 124 of the blade.

[0129] Regarding the end drying unit 1312 close to the left end 123 of the blade, it can be understood that, please refer to Figure 10 , when the left end 123 of the blade continues to extend to the left according to the shape of the water absorption structure 12, the extended part passes through the end drying unit 1312.

[0130] Regarding the end drying unit 1312 close to the right end 124 of the blade, it can be understood that, please refer to Figure 10 , when the right end 124 of the blade continues to extend to the right according to the shape of the water absorption structure 12, the extended part passes through the end drying unit 1312.

[0131] When the cleaning device 100 performs the operation of sucking the ground water with the water absorption structure 12, when the cleaning device 100 turns, the water can be thrown out from the two ends of the water absorption structure 12, i.e. the left end 123 and the right end 124 of the blade, and the water thrown out from the two ends of the water absorption structure 12 can be dried by the end drying unit 1312.

[0132] In an example, please refer to Figure 10The end wiping unit 1312 on the left side and the rear wiping unit 1311 adjacent thereto are spaced apart, and the end wiping unit 1312 on the right side and the rear wiping unit 1311 adjacent thereto are spaced apart; in other examples, the end wiping unit 1312 on the left side and the rear wiping unit 1311 adjacent thereto can be in contact, and the end wiping unit 1312 on the right side and the rear wiping unit 1311 adjacent thereto can be in contact.

[0133] In the embodiment, the end wiping unit 1312 is arranged to wipe the sewage that is thrown out from the end of the water absorption structure 12, thereby improving the cleaning effect of the cleaning module 1.

[0134] In one embodiment, when each wiping unit 131 is projected perpendicularly to the cleaning direction of the cleaning module 1, the projections of two adjacent wiping units 131 intersect.

[0135] Please refer to Figure 10 , Figure 10 The direction indicated by the arrow X is the cleaning direction of the cleaning module 1, and the direction indicated by the arrow Y is perpendicular to the direction indicated by the arrow X, that is, when each wiping unit 131 is projected in the direction of the arrow X, the projections of two adjacent wiping units 131 intersect.

[0136] Specifically, please refer to Figure 10 , Figure 10 The dashed line L3 in Figure 10 illustrates the tangent line of one of the rear wiping units 1311 (which can be referred to as a first rear wiping unit), and the dashed line L4 illustrates the tangent line of another of the rear wiping units 1311 (which can be referred to as a second rear wiping unit). As shown in , the dashed line L3 passes through the second rear wiping unit, and the dashed line L4 passes through the first rear wiping unit, so that when the first rear wiping unit and the second rear wiping unit are projected perpendicularly to the cleaning direction of the cleaning module 1, the projections of the first rear wiping unit and the second rear wiping unit intersect.

[0137] When the dashed line L3 and the dashed line L4 in Figure 10 coincide, at this time, when the first rear wiping unit and the second rear wiping unit are projected perpendicularly to the cleaning direction of the cleaning module 1, the projections of the first rear wiping unit and the second rear wiping unit intersect at a point, at this time, it can still be considered that the projections of the first rear wiping unit and the second rear wiping unit intersect.

[0138] Please refer to Figure 10, the tangent line L1 of the left end wiping and drying unit 1312 is shown, which passes through the rear wiping and drying unit 1311 (i.e. the first rear wiping and drying unit) adjacent to the end wiping and drying unit 1312, and the projection of the left end wiping and drying unit 1312 and the first rear wiping and drying unit intersect when they are projected perpendicularly to the cleaning direction of the cleaning module 1. Similarly, referring to Figure 10 , the projection of the right end wiping and drying unit 1312 and the rear wiping and drying unit 1311 adjacent to it intersect when they are projected perpendicularly to the cleaning direction of the cleaning module 1.

[0139] In the embodiments of the present application, by setting the projections of the adjacent two wiping and drying units 131 intersect when they are projected perpendicularly to the cleaning direction of the cleaning module 1, the wiping and drying assembly 13 can better perform the wiping and drying operation on the ground, and avoid that the water stains of the two wiping and drying units 131 are not wiped.

[0140] Please refer to Figure 11-15 , Figure 11 for the structural schematic diagram of the cleaning module 1 provided in the embodiments of the present application; Figure 12 for the structural schematic diagram of the driving device 15 provided in the embodiments of the present application; Figure 13 for another structural schematic diagram of the driving device 15 provided in the embodiments of the present application; Figure 14 for the structural schematic diagram of the cleaning module 1 provided in the embodiments of the present application; Figure 15 for the structural schematic diagram of the transmission structure 152 and the wiping and drying assembly 13 provided in the embodiments of the present application; Figure 16 for the sectional view of the transmission structure 152 and the wiping and drying assembly 13 provided in the embodiments of the present application.

[0141] In an embodiment, please refer to Figure 11 , the cleaning module 1 further comprises a driving device 15, which is arranged on the support 11, and each wiping and drying unit 131 is connected with the driving device 15, and the driving device 15 is used to drive each wiping and drying unit 131 to rotate, i.e. the driving device 15 can drive the wiping and drying unit 131 to rotate along the axis thereof.

[0142] In an example, the rotation of each wiping and drying unit 131 is independent of each other, i.e. when one of the wiping and drying units 131 rotates, it will not affect the rotation of the other wiping and drying units 131 together, for example, each wiping and drying unit 131 is connected with a motor, so as to control the rotation of each wiping and drying unit 131 respectively.

[0143] In an example, part of the wiping and drying units 131 rotate synchronously, for example, the driving device 15 comprises two or more motors, and part of the wiping and drying units 131 are drivingly connected with the same motor, so as to reduce the number of motors and reduce the cost.

[0144] As described above, when the negative pressure generating assembly is working, the sewage tank and the water absorption cavity 121 of the water absorption structure 12 can generate negative pressure to absorb the sewage on the ground. In an example, the cleaning device 100 can control the negative pressure generating assembly and the driving device 15 to work simultaneously. For example, when the cleaning device 100 receives an instruction to recover the sewage on the ground, the cleaning device 100 controls the negative pressure generating assembly to work, and simultaneously controls the driving device 15 to work, so that the negative pressure generating assembly works to generate negative pressure in the sewage tank and the water absorption cavity 121 of the water absorption structure 12 to absorb the sewage on the ground, and the driving device 15 works to drive the rotating of each drying unit 131 to perform the drying operation on the ground.

[0145] In an example, the cleaning device 100 can control only the driving device 15 to work, and control the negative pressure generating assembly not to work, so that the driving device 15 works to drive the rotating of each drying unit 131 to perform the drying operation on the ground, which can be suitable for a scene where the sewage on the ground is not needed to be absorbed and only the ground is needed to be dried.

[0146] In the embodiment, the driving device 15 is arranged, so that the drying unit 131 can be conveniently rotated to perform the drying operation on the ground, which is beneficial to improve the drying effect of the cleaning module 1 on the ground.

When the driving motor 151 is started, each drying unit 131 can be driven to rotate by the transmission structure 152, i.e., each drying unit 131 rotates synchronously.

[0148] As described above, the support 11 is further provided with the corner cleaning assembly 16 for cleaning the corners on the ground. In an example, the driving motor 151 and the corner driving motor 162 are the same motor, i.e., when the corner cleaning element 161 is connected with the transmission structure 152, the driving motor 151 is started, and the transmission structure 152 can drive the rotating of each drying unit 131 and the corner cleaning element 161, which is beneficial to reduce the number of motors and reduce the cost. In other examples, the drying unit 131 and the corner cleaning element 161 are driven by different motors, so as to conveniently control the rotating of the drying unit 131 and the corner cleaning element 161.

[0149] In an example, the transmission structure 152 adopts gear transmission, i.e., the transmission structure 152 includes a plurality of meshing gears, which is beneficial to accurate and stable transmission.

[0150] In the embodiment, each drying unit 131 is connected with the transmission structure 152, and the driving motor 151 is connected with the transmission structure 152, so that one driving motor 151 can drive each drying unit 131 to rotate, and the cost of the cleaning module 1 can be reduced.
