[0048] In order to solve the problem that the water outlet of the cleaning module is easily clogged and difficult to maintain after working for a long time, the present application provides a cleaning module, by installing a cleaning part and a diverter part on the module body, and using the diverter part to guide the cleaning liquid to the cleaning part to achieve the cleaning function. At the same time, the diverter part and the module body are arranged to be detachably connected, so that the diverter part can be removed and replaced separately, which is convenient for maintenance.

[0049] See also Figure 1A cleaning module 1 provided in one embodiment of the present application includes a module body 10, a cleaning member 20 and a diverter member 30. The module body 10 may specifically be a shell structure provided with a mounting cavity, and a movable wheel, such as a universal wheel, may be provided at the bottom of the shell structure. The cleaning member 20, such as a roller brush, is installed on the module body 10, and a part of the roller brush is located in the mounting cavity to reduce the overall volume of the cleaning module 1, and another part of the roller brush extends out of the mounting cavity so that the roller brush can clean the debris on the ground by rolling, and as the movable wheel moves, the roller brush can clean the debris on the moving path. Among them, the number of roller brushes may be one, two or more.

[0050] Combination Figure 1 and Figure 2 , the diverter 30 is provided with a drainage channel 31, a drainage inlet 32 ​​and a drainage outlet 33, and the drainage inlet 32 ​​and the drainage outlet 33 are both connected to the drainage channel 31. Among them, the drainage inlet 32 ​​is connected to the cleaning liquid source, so that the cleaning liquid provided by the cleaning liquid source enters the drainage channel 31 through the drainage inlet 32, flows along the drainage channel 31 and flows out from the drainage outlet 33. The drainage outlet 33 is arranged relative to a part of the cleaning member 20, so that the cleaning liquid flowing out of the drainage outlet 33 flows to the cleaning member 20, so that the cleaning liquid can be used to scrub the ground during the cleaning process of the cleaning member 20, thereby improving the cleaning effect and efficiency; of course, in other embodiments, the drainage outlet 33 can also be arranged at the front side of the cleaning member 20, at this time, the cleaning liquid is sprayed or dripped onto the ground in front of the cleaning member 20 through the drainage outlet 33, and when the cleaning device moves forward with the cleaning module 1 to work, the ground with the cleaning liquid is scrubbed, thereby improving the cleaning effect and efficiency.

[0051] When there are multiple roller brushes, the diverter 30 can be set directly above the roller brush located on the front side of the module body 10, so that after the cleaning liquid flows out from the drainage outlet 33 on the diverter 30, it first wets the ground as the roller brush on the front side rolls, so that the cleaning liquid can also be used for cleaning during the cleaning process of the roller brush on the rear side, thereby improving the cleaning effect.

[0052] Optionally, a plurality of drainage outlets 33 are provided on the diverter 30, and the plurality of drainage outlets 33 are distributed at intervals, so that the cleaning liquid can be evenly dispersed and then flow out.

[0053] Furthermore, the diverter 30 is detachably mounted on the module body 10, so that the diverter 30 can be removed separately without disassembling the cleaning module 1 as a whole. When the diverter 30 needs to be maintained, for example, when the drainage channel 31, drainage inlet 32 ​​or drainage outlet 33 on the diverter 30 is blocked or corroded by scale and needs to be cleaned, the diverter 30 can be removed separately for maintenance, which improves the convenience of maintenance and reduces the cost of maintenance.

[0054] Combination Figure 1 and Figure 3 Optionally, a slide groove 11 is provided on the module body 10, and the diverter 30 is slidably connected to the slide groove 11. The slide groove 11 is located above the cleaning member 20, and the bottom of the slide groove 11 is provided with a plurality of through holes 111 facing the cleaning member 20, and the drainage outlet 33 is connected to the slide groove 11. In this way, the installation structure of the diverter 30 is simple, and the diverter 30 can be installed and removed from the side of the cleaning module 1 by sliding, eliminating the heavy operation of tilting the equipment sideways when maintaining the traditional cleaning equipment, making the maintenance operation more convenient and quick.

[0055] Optionally, the chute 11 extends longitudinally along the first direction X, and a socket 112 is provided at one end of the chute 11 along the first direction X, and the diverter 30 is configured to be able to enter and exit the chute 11 along the first direction X through the socket 112, so as to facilitate the sliding connection between the diverter 30 and the chute 11. Exemplarily, when the cleaning member 20 is a roller brush, the first direction X is parallel to the axial direction of the roller brush. It is understandable that the other end of the chute 11 can be closed to facilitate the determination of whether the diverter 30 is plugged in place during the installation process.

[0056] Optionally, a positioning protrusion is provided in the slide groove 11, and the positioning protrusion and the socket 112 are respectively located at opposite ends of the slide groove 11 along the first direction X, and the positioning protrusion protrudes from the inner side wall of one end of the slide groove 11 toward the socket 112. A positioning recess is provided on the diverter 30, and the positioning recess is snap-fitted with the positioning protrusion. For example, the positioning recess is configured as a C-shape or a U-shape, and the shape of the positioning protrusion matches it. In this way, during the installation process of the diverter 30, when the positioning recess is snap-fitted with the positioning protrusion, it can be determined that the diverter 30 is plugged in place. In addition, since the cooperation between the positioning recess and the positioning protrusion increases the contact area between the diverter 30 and the slide groove 11, the installation between the diverter 30 and the slide groove 11 is more stable.

[0057] Combination Figure 1 , Figure 4 and Figure 5 In some embodiments, the cleaning module 1 further includes a spring buckle 40 and an elastic driving member 41. The spring buckle 40 has a connecting end and a clamping end opposite to each other, and the connecting end is rotatably connected to the diverter 30. Exemplarily, the diverter 30 is provided with a mounting hole, and the connecting end of the spring buckle 40 is provided with a connecting hole. The fastener passes through the connecting hole and is connected with the mounting hole, so that the connecting end of the spring buckle 40 and the diverter 30 can be rotatably connected.

[0058] One end of the elastic driving member 41 is connected to the diverter 30, and the other end is connected to the clamping end of the snap 40, so as to apply a rebound force to the clamping end toward the inner wall of the chute 11. The elastic driving member 41 can be a spring. Based on this, the rebound force of the spring can make the snap 40 press against the inner wall of the chute 11, and when there is no external force, the diverter 30 is fixed in the chute 11, so that the diverter 30 is stably installed.

[0059] Optionally, an arc-shaped protrusion is provided on the outer side of the spring buckle 40, and the arc-shaped protrusion abuts against the inner wall of the slide groove 11, so that the force between the spring buckle 40 and the slide groove 11 can be made stronger, thereby improving the installation stability of the diverter 30.

[0060] Combination Figures 2 to 5 In some embodiments, the chute 11 is provided with an inlet channel and a steering channel 113 that are interconnected, the inlet channel extends along the second direction Y, and the steering channel 113 extends along the first direction X. A hollow connector 34 is installed on the diverter 30, and the connector 34 can be sealed and plugged into the steering channel 113, and the outlet of the connector 34 is connected to the drainage inlet 32. The second direction Y intersects with the first direction X. Among them, a sealing ring 341 can be arranged between the connector 34 and the inner wall of the steering channel 113 to improve the sealing performance. Exemplarily, a liquid inlet connector 114 is provided on the chute 11, and the liquid inlet connector 114 is constructed in an L shape, one end of which is connected to the cleaning liquid source, and the other end is connected to the liquid inlet channel on the chute 11. In this way, the cleaning liquid provided by the cleaning liquid source passes through the liquid inlet connector 114 and then passes through the liquid inlet channel and the steering channel 113 in sequence, enters the connector 34, and enters the drainage channel 31 of the diverter 30 through the connector 34.

[0061] Optionally, a pull ring 35 is provided at one end of the flow divider 30, and the connector 34 and the pull ring 35 are an integral structure. In this way, the pull ring 35 pushes and pulls the flow divider 30, so that the flow divider 30 can slide relative to the chute 11. At the same time, the push and pull action of the pull ring 35 can realize the movement of the connector 34 in the turning channel 113 of the chute 11.

[0062] Continue reading Figures 2 to 5In some embodiments, the diverter 30 is constructed as a diverter groove 30a with a concave middle portion, and the drainage channel 31 is arranged at the bottom of the diverter groove 30a. The cleaning module 1 also includes a sealing pad 50, a pressing plate 60 and a locking assembly 70. The sealing pad 50 and the pressing plate 60 are sequentially stacked in the diverter groove 30a, and the sealing pad 50 covers the drainage channel 31. The locking assembly 70 presses the pressing plate 60 to the side surface of the sealing pad 50 away from the drainage channel 31. Optionally, the sealing pad 50 and the pressing plate 60 are provided with a through hole, which is connected to the drainage inlet 32 ​​on the diverter groove 30a. Among them, the sealing pad 50 can be specifically a sheet of the same shape as the pressing plate 60, and the material can be silicone. In this way, the drainage channel 31 in the diverter groove 30a is covered by the sealing pad 50, and the pressing plate 60 is pressed on the sealing pad 50 by the locking assembly 70, so that the drainage channel 31 forms a closed channel, which can prevent leakage.

[0063] Optionally, a sealing ring 341 is provided between the pressing plate 60 and the connector 34 , and the sealing ring 341 surrounds the through hole of the pressing plate 60 , thereby improving the sealing performance at the drainage inlet 32 ​​.

[0064] Optionally, a mounting position for mounting the spring buckle 40 is provided on the diverter groove 30a, and the inner side wall of the diverter groove 30a protrudes inward at the mounting position, and the sealing gasket 50 and the pressure plate 60 are both provided with grooves for avoiding the protrusion.

[0065] See also Figure 5 In some embodiments, a first avoidance hole 61 is provided on the pressure plate 60, a second avoidance hole 51 is provided on the sealing gasket 50, and a first mounting hole 30a1 is provided at the bottom of the diverter groove 30a. The positions of the first avoidance hole 61, the second avoidance hole 51 and the first mounting hole 30a1 correspond to each other.

[0066] Combination Figure 5 , Figure 6 and Figure 7 The locking assembly 70 includes a first fastener 71, a limiting sleeve 72, a second fastener 73 and a compression spring 74. The first fastener 71 has a first end and a second end opposite to each other, and the first end of the first fastener 71 passes through the first avoidance hole 61 and the second avoidance hole 51 from top to bottom in sequence and then is matched and connected with the first mounting hole 30a1, so that the first fastener 71 is fixed on the diverter groove 30a, and at the same time, the horizontal dislocation and sliding of the pressing plate 60 and the sealing gasket 50 are limited.

[0067] The second end of the first fastener 71 is provided with a second mounting hole extending along the axial direction of the first fastener 71, and the first fastener 71 is provided with a first annular protrusion 711 located between the first end and the second end. The first annular protrusion 711 surrounds the outer surface of the first fastener 71 along the circumference of the first fastener 71.

[0068] Combination Figure 8 and Fig. 9 The limiting sleeve 72 is sleeved outside the first fastener 71, and a second annular protrusion 721 is provided on the inner side wall of the limiting sleeve 72. The second annular protrusion 721 surrounds the inner surface of the limiting sleeve 72 along the circumference of the limiting sleeve 72, and the inner diameter of the second annular protrusion 721 is smaller than the outer diameter of the first annular protrusion 711. The limiting sleeve 72 can be a hand-tightened knurled structure to facilitate the operation of the limiting sleeve 72. Based on this, under the action of the gravity of the limiting sleeve 72 itself, the second annular protrusion 721 will overlap the first annular protrusion 711.

[0069] The second fastener 73 is connected in cooperation with the second mounting hole, and the diameter of the end cap of the second fastener 73 is larger than the outer diameter of the second end of the first fastener 71. The compression spring 74 is sleeved on the second end, and the two ends of the compression spring 74 are respectively in contact with the end cap of the second fastener 73 and the second annular protrusion 721. The second annular protrusion 721 and the end cap of the second fastener 73 restrict the compression spring 74 therebetween. When the spring is compressed, the rebound force of the spring acts on the second annular protrusion 721, so that the limiting sleeve 72 is subjected to downward pressure.

[0070] Combination Figure 4 , Figure 5 , Figure 8 and Fig. 9 The outer diameter of the limiting sleeve 72 is larger than the aperture of the first avoidance hole 61, so that the limiting sleeve 72 can transmit the elastic force of the compression spring 74 to the pressing plate 60. In this way, the limiting sleeve 72 presses the pressing plate 60 downward, so that the pressing plate 60 can press the sealing gasket 50 tightly against the bottom of the diverter groove 30a, thereby achieving a good sealing effect.

[0071] Combination Figure 4 , Figure 5 , Figure 6 and Fig.10 Optionally, a plurality of pits 62 are provided on the surface of the side of the pressure plate 60 facing away from the sealing pad 50, and the plurality of pits 62 are arranged at intervals along the circumference of the first avoidance hole 61. Among them, the plurality of pits 62 can be evenly spaced along the circumference of the first avoidance hole 61. A plurality of protrusions 722 are provided on the end surface of the limiting sleeve 72, and the plurality of protrusions 722 can be embedded in the plurality of pits 62 one by one to limit the rotation of the limiting sleeve 72. In this way, not only can the limiting sleeve 72 be pressed against the pressure plate 60 under the elastic force of the compression spring 74, but also the limiting effect between the protrusions 722 and the pits 62 can prevent the limiting sleeve 72 from accidentally rotating relative to the pressure plate 60 when the cleaning module 1 vibrates, thereby making the sealing effect more stable and preventing the sealing effect from failing due to vibration.

[0072] Combination Figure 8 and Fig. 9It can be understood that, when the second fastener 73 is locked, when the height H1 that the limiting sleeve 72 can be lifted is less than the thickness H of the first annular protrusion 711 along the axial direction of the first fastener 71, that is, when the difference H1 between the length of the portion of the first fastener 71 located above the first annular protrusion 711 and the thickness of the second annular protrusion 721 is less than the thickness H of the first annular protrusion 711 along the axial direction of the first fastener 71, even if the limiting sleeve 72 is lifted, the limiting sleeve 72 and the first annular protrusion 711 will not separate, and the relative rotation between the two is restricted by each other. At this time, the limiting sleeve 72 can still transmit torque within the lifting height range.

[0073] Furthermore, when the depth of the pit 62 is h, if the protrusion 722 on the end face of the limit sleeve 72 is not embedded in the pit 62, the lifting height of the limit sleeve 72 is h. At this time, by designing h to be less than H1, it can be ensured that the torque can be transmitted between the limit sleeve 72 and the first fastener 71.

[0074] Combination Figure 6 , Figure 7 and Fig.10 Optionally, the protrusion 722 on the end surface of the limiting sleeve 72 has an inclined surface 7221 that is inclined relative to the end surface of the limiting sleeve 72. In this way, by manually rotating the limiting sleeve 72, the inclined surface 7221 can slide over the edge of the pit 62, so that the protrusion 722 leaves the pit 62. After the protrusion 722 leaves the pit 62, the maximum stroke of the compression spring 74 is compressed to the depth h of the pit 62, and h is less than H1, so the limiting sleeve 72 can still transmit torque. At the same time, due to the existence of the protrusion 722 and the specific orientation of the inclined surface 7221, the limiting sleeve 72 can be loosened only when the limiting sleeve 72 is lifted to a height greater than h, thereby achieving the effect of preventing loosening.

[0075] Furthermore, in the above embodiments, the first fastener 71 and the second fastener 73 are specifically selected as screws, and correspondingly, the first mounting hole 30a1 and the second mounting hole are specifically selected as threaded holes adapted thereto. It can be understood that the above specifically selected parts are only examples, and are not actually limited to the installation and fixation of the above components by means of screws and threaded holes.

[0076] See also Fig.11 In other embodiments, the overall structure of the cleaning module 1 is similar to the overall structure of the cleaning module 1 in the above embodiments, and the main difference includes the different structure of the locking assembly 70.

[0077] See also Figure 12-14Specifically, the pressing plate 60 is provided with a third mounting hole 63, the sealing gasket 50 is provided with a third avoidance hole 52, and the bottom of the diverter groove 30a is provided with a fourth avoidance hole 30a2. The locking assembly 70 includes a third fastener 75, which passes through the third avoidance hole 52 and the fourth avoidance hole 30a2 in sequence and is matched and connected with the third mounting hole 63, and the end cap of the third fastener 75 abuts against the diverter groove 30a. In this way, the third fastener 75 can stably lock the diverter groove 30a, the sealing gasket 50, and the pressing plate 60, and the operation is convenient and fast, and the structure is stable.

[0078] Optionally, the third avoidance hole 52 is a mounting hole. Based on this, the connection of the third fastener 75 is more stable.

[0079] Optionally, the third avoidance hole 52 is a through hole 111 with a smooth inner wall, which has a simple structure and simplifies the molding process.

[0080] Optionally, the fourth avoidance hole 30a2 includes two avoidance parts that are connected and have unequal apertures, the avoidance part with a smaller aperture is used to avoid the screw of the third fastener 75, and the avoidance part with a larger aperture is used to avoid the end cap of the third fastener 75. In this way, when the third fastener 75 is tightened, the end cap of the third fastener 75 is hidden in the fourth avoidance hole 30a2, thereby preventing the third fastener 75 from protruding relative to the outer surface of the diverter slot 30a and hindering the diverter slot 30a from sliding.

[0081] Furthermore, the locking assembly 70 further includes an installation tool 76 adapted to the end cap of the third fastener 75, and the installation tool 76 is configured to tighten or loosen the third fastener 75. The installation tool 76 is detachably disposed between the pressing plate 60 and the sealing gasket 50, which facilitates the storage of the installation tool 76, thereby facilitating the user to flexibly remove the installation tool 76 according to needs and use the installation tool 76 to loosen the fastener.

[0082] Optionally, a groove is provided on one side of the pressing plate 60 facing the sealing gasket 50, and the groove extends to one end of the pressing plate 60 in the length direction, and a part of the installation tool 76 is embedded in the groove, and the other part extends out of the groove, so that the installation tool 76 is not easy to fall off, and it is convenient for the user to extract the installation tool 76 from the end of the pressing plate 60. In addition, such a configuration can ensure that the pressing plate 60 and the sealing gasket 50 are tightly pressed together.

[0083] Optionally, in a tightened state, the end surface of the third fastener 75 is flush with the surface of the pressing plate 60, thereby avoiding interference with the sliding process of the diverter slot 30a.

[0084] Furthermore, in the above embodiments, the third fastener 75 is specifically selected as a hexagon socket screw, and accordingly, the third mounting hole 63 is specifically selected as a threaded hole adapted thereto, and the mounting tool 76 is specifically selected as a hexagon socket wrench adapted thereto. It can be understood that the above-mentioned specifically selected parts are limited to examples, and are not actually limited to the installation and fixation of the above-mentioned components by means of screws and threaded holes, and are not limited to the installation and removal of the hexagon socket screws by means of a hexagon socket wrench.

[0085] See also Figure 2 In some embodiments, the drainage channel 31 includes a mainstream channel 311 and a plurality of branch channels 312, the inlet of the mainstream channel 311 is connected to the drainage inlet 32, the outlet of the mainstream channel 311 is simultaneously connected to the inlets of the plurality of branch channels 312, and the outlet of the branch channel 312 is connected to the drainage outlet 33. Optionally, the drainage channel 31 is configured to be recessed downward from the surface of the diverter 30. Optionally, the number of branch channels 312 is equal to the number of drainage outlets 33 and corresponds one to one. Based on this, the plurality of branch channels 312 divert the cleaning liquid in the mainstream channel 311, and the outlets of the plurality of branch channels 312 simultaneously flow out the cleaning liquid, so that the cleaning liquid can be evenly dispersed during the cleaning process of the cleaning module 1, thereby improving the cleaning effect.

[0086] Further, the multiple branch channels 312 include multiple primary branch channels 3121 and multiple secondary branch channels 3122, the inlet of the primary branch channel 3121 is connected to the outlet of the main channel 311, the outlet of the primary branch channel 3121 is connected to the inlet of the secondary branch channel 3122, the outlet of the secondary branch channel 3122 is connected to the drainage outlet 33, and the length of each primary branch channel 3121 is equal, and the length of each secondary branch channel 3122 is equal. In this way, the distance of the cleaning liquid from the drainage inlet to the drainage outlet 33 is equal, so that the water pressure of the water outlets at multiple points remains consistent.

[0087] Optionally, the flow area of ​​the main flow channel 311 is larger than the flow area of ​​the branch flow channel 312. Optionally, the flow area of ​​the primary branch flow channel 3121 is larger than the flow area of ​​the secondary branch flow channel 3122. In this way, the flow area from the drainage inlet to the drainage outlet 33 decreases step by step, so that although the amount of water in each branch flow channel 312 is reduced after the diversion, the water pressure can remain unchanged or decrease to a small extent.

[0088] See also Fig.15Optionally, an avoidance recess 3123 is provided at the connection point between the first-level branch channel 3121 and the second-level branch channel 3122, and the avoidance recess 3123 avoids the fourth avoidance hole 30a2, so that the fourth avoidance hole 30a2 is separated from the first-level branch channel 3121 and the second-level branch channel 3122, thereby preventing the fluid in the first-level branch channel 3121 or the second-level branch channel 3122 from entering the fourth avoidance hole 30a2.

To make the description concise, not all possible combinations of the technical features in the above-described 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.
