[0064] Referring to FIG. 1-2, the cleaning base station 200 provided by the embodiments of the present application comprises a base 210, a cleaning assembly 220 and a driving assembly 230, wherein the base 210 is provided with a containing space for parking the cleaning device 100, and a liquid discharge groove 2101 on the base 210 is directed to the containing space. The base 210 comprises a base plate 211 and a cleaning disc 212, wherein the driving assembly 230 is arranged on the base plate 211, the cleaning disc 212 is arranged on the side of the base plate 211 facing the containing space and connected with the base plate 211, and the cleaning assembly 220 is arranged in the cleaning disc 212, so that when the cleaning device 100 is parked in the containing space, the cleaning assembly 130 is just above the cleaning assembly 220. When the cleaning assembly 130 is lifted relative to the base 210 to abut against the upper surface of the cleaning assembly 220, the cleaning assembly 220 rotating relative to the cleaning assembly 130 can clean the cleaning assembly 130.

[0065] The driving assembly 230 can be connected with the cleaning assembly 220 through the cleaning disc 212 to drive the cleaning assembly 220 to rotate relative to the base 210.

[0066] Specifically, the driving assembly 230 can drive the cleaning assembly 220 to rotate forward or reversely relative to the base plate 211 according to the need, so as to meet different cleaning requirements. In order to adapt to the need of rotating cleaning, the cleaning assembly 220 has a circular or similar circular structure in the axial direction.

[0067] In some embodiments, the cleaning base station 200 can have two cleaning assemblies 220 arranged side by side, as shown in FIG. 1-2.

[0068] Referring to FIG. 2, in order to facilitate the transmission connection between the cleaning assembly 220 and the driving assembly 230, the two cleaning assemblies 220 arranged side by side are connected with the driving assembly 230 through the related transmission structure in the base plate 211, so as to rotate under the driving of the driving assembly 230 to clean the cleaning assembly 130 above.

[0069] Referring to FIG. 3, the liquid discharge groove 2101 arranged on the base 210 is located on the side of the cleaning assembly 220 and can cooperate with the cleaning assembly 220 when the cleaning assembly 220 rotates to the appropriate position.

[0070] The cleaning assembly 220 comprises a cleaning plate 221 and a liquid guide groove 222. The cleaning plate 221 can rotate around the axis under the driving of the driving assembly 230. When the cleaning plate 221 rotates to the appropriate position, the liquid guide groove 222 can be just opposite to the liquid discharge groove 2101 arranged on the base 210 to cooperate, as shown in FIG. 3.

[0071] The cleaning liquid released by the base 210 through the liquid discharge groove 2101 can flow to the upper surface of the cleaning plate 221 through the liquid guide groove 222 arranged opposite to the liquid discharge groove 2101. When the upper surface of the cleaning plate 221 abuts against the cleaning assembly 130 to be cleaned, the cleaning liquid can achieve the wetting of the cleaning assembly 130.

[0072] In order to adapt to the needs of rotary cleaning, the cleaning plate 221 is circular or similar circular in the axial direction, and at least part of the liquid guide groove 222 is arranged at the outer peripheral edge of the cleaning plate 221.

[0073] In some embodiments, the cleaning assembly 220 includes the cleaning plate 221 and the liquid guide groove 222, as shown in FIGS. 4-6. The side of the cleaning plate 221 facing the base 211 is defined as the lower surface, and the side away from the base 211 is defined as the upper surface. The upper surface of the cleaning plate 221 is provided with a plurality of cleaning structures 224. When the upper surface of the cleaning plate 221 cooperates with the mop 131 of the cleaning assembly 130, the cleaning structures 224 can scrape and press the surface of the mop 131 and remove the impurities and dirt on the surface of the mop 131 as the cleaning plate 221 rotates, so as to achieve the purpose of cleaning the cleaning assembly 130.

[0074] In the process of cleaning the cleaning assembly 130 by the cleaning assembly 220, the cleaning assembly 130 interferes with the cleaning structures 224, and at the same time, the relative rotation between the cleaning assembly 130 and the cleaning plate 221 is generated, so that the cleaning assembly 130 rotates relative to the cleaning plate 221 to circulate and interfere with each cleaning structure 224, and finally achieve the cleaning of the cleaning assembly 220.

[0075] Specifically, the cleaning structures 224 can be block-shaped or strip-shaped structures protruding relative to the upper surface of the cleaning plate 221. The cleaning structures 224 can be an integral structure with the cleaning plate 221, or can be made of silica gel or rubber material fixedly arranged on the upper surface of the cleaning plate 221. When cleaning the mop 131 of the cleaning assembly 130, the cleaning structures 224 can be closely combined with the mop 131 and scrape the mop 131 as the relative rotation between the cleaning plate 221 and the cleaning assembly 130. When the mop 131 passes through the cleaning structures 224, the cleaning structures 224 can scrape and press the surface of the mop 131 to remove the dirt and water on the mop 131, so that the mop 131 can be cleaned more quickly.

[0076] Please refer to FIG. 4, the cleaning structure 224 is in the form of a protrusion. In addition, the upper surface of the cleaning plate 221 is provided with a flow guide rib 223, and the middle part of the cleaning plate 221 is provided with a sewage outlet 2213 penetrating the upper surface and the lower surface. The liquid guide groove 222 is located on the upper surface of the cleaning plate 221 and partially extends outwardly along the radial direction of the cleaning plate 221 to protrude relative to the outer circumferential edge of the cleaning plate 221.

[0077] Under the driving of the driving assembly 230, the cleaning plate 221 can rotate around the shaft, and the dirt on the cleaning plate 221 can fall into the cleaning liquid under the action of the cleaning structure 224 and the flow guide rib 223 and form sewage. The sewage can flow to the sewage outlet 2213 under the guidance of the flow guide rib 223 and be discharged from below the cleaning plate 221 through the sewage outlet 2213.

[0078] In some embodiments, the cleaning plate 221 can have a disc-shaped, plate-shaped or flat plate-shaped structure as a whole. Please refer to FIG. 4, the cleaning plate 221 is provided with an inner ring cleaning plate 2211 and an outer ring cleaning plate 2212 along the radial direction, and the sewage outlet 2213 is located in the middle part of the inner ring cleaning plate 2211. The inner ring cleaning plate 2211 and the outer ring cleaning plate 2212 can be an integral structure, wherein the cleaning structure 224 is distributed on the upper surfaces of the inner ring cleaning plate 2211 and the outer ring cleaning plate 2212, and the flow guide rib 223 is located on the upper surface of the inner ring cleaning plate 2211.

[0079] The flow guide rib 223 is arranged in a spiral along the radial direction of the cleaning plate 221, which can guide part of the cleaning liquid on the upper surface of the cleaning plate 221 to flow to the middle part of the cleaning plate 221 and be discharged through the sewage outlet 2213. During the cleaning process of the cleaning assembly 130, the flow guide rib 223 guides the cleaning liquid to gather towards the middle part of the cleaning plate 221, so that the cleaning liquid contacts and wets the middle part of the cleaning assembly 130, achieving sufficient wetting of the middle part of the cleaning assembly 130, which helps the dirt in the middle part of the cleaning assembly 130 to dissolve in the cleaning liquid, thereby improving the cleaning effect of the middle part of the cleaning assembly 130 and achieving the purpose of improving the overall cleaning uniformity of the cleaning assembly 130, so that the cleaning assembly 130 can be better cleaned.

[0080] Please refer to FIG. 4, during the cleaning process of the cleaning assembly 130, sewage needs to be discharged. The sewage located on the outer ring cleaning plate 2212 can be thrown outward under the action of centrifugal force as the cleaning assembly 130 and / or the cleaning assembly 220 rotates; the sewage located on the upper surface of the inner ring cleaning plate 2211 can be discharged through the sewage outlet 2213 under the guidance of the flow guide rib 223. Of course, part of the sewage located on the upper surface of the inner ring cleaning plate 2211 can also flow to the sewage outlet 2213 under the guidance of gravity and be discharged.

[0081] Referring to FIG. 4, one end of the guide fin 223 is located at the joint of the inner ring cleaning plate 2211 and the outer ring cleaning plate 2212, and the other end extends along a spiral curve or a similar curve to the drain port 2213, for guiding the liquid such as sewage and / or cleaning liquid on the inner ring cleaning plate 2211 to the drain port 2213 and discharging through the drain port 2213. In the axial direction of the cleaning plate 221, the projection of the guide fin 223 extends outward or inward along the radial direction and the circumferential direction of the inner ring cleaning plate 2211 to connect the radial inner contour and the radial outer contour respectively formed on both sides of the projection of the inner ring cleaning plate 2211 in the radial direction. At this time, the overall shape of the guide fin 223 is similar to a planar spiral line. When the cleaning assembly 130 and the cleaning assembly 220 rotate relative to each other, the liquid on the inner ring cleaning plate 2211 will generate a certain force due to rotation, and the inner rotation structure formed by the guide fin 223 can resist the force generated by the liquid flow and help guide the liquid flow to the middle part of the inner ring cleaning plate 2211 along the guide fin 223, and then discharge through the drain port 2213, thereby achieving effective cleaning of the inner ring of the cleaning assembly 130 (i.e. the middle part of the cleaning assembly 130) and sewage discharge.

[0082] In order to further improve the flow direction guiding effect of the guide fin 223 on the liquid flow, in some embodiments, the guide fin 223 can be inclined from the root connecting the inner ring cleaning plate 2211 to the top away from (i.e. away from) the inner ring cleaning plate 2211 to the middle part of the inner ring cleaning plate 2211. At this time, the guide fin 223 can provide greater centripetal force to the rotating liquid flow. The liquid flow can further overcome the centrifugal force generated by the relative rotation under the guidance of the guide fin 223, and then flow to the drain port 2213 under the guidance of the guide fin 223, and in this process, the cleaning of the inner ring of the cleaning assembly 130 and the rapid discharge of sewage generated during the cleaning process are simultaneously achieved.

[0083] Referring to FIG. 4, the number of the above-mentioned guide fins 223 is at least two, and the two guide fins 223 are uniformly spaced. The ends of the plurality of guide fins 223 are uniformly spaced along the radial direction of the inner ring cleaning plate 2211. By reasonably setting the number of guide fins 223, it can be ensured that the guide fins 223 can uniformly and comprehensively guide the liquid flow on the surface of the inner ring cleaning plate 2211, so as to improve the drainage efficiency.

[0084] In some embodiments provided in the present application, the upper surfaces of the inner cleaning plate 2211 and the outer cleaning plate 2212 are located on the same plane, or the middle part of the inner cleaning plate 2211 can be recessed downward relative to the side adjacent to the outer cleaning plate 2212 and form an inclined surface 22111. At this time, the upper surface of the cleaning plate 221 forms an inclined surface 22111 with the middle part recessed downward, and the sewage outlet 2213 is located at one end of the inclined surface 22111 close to the base 210, i.e., the middle part of the inclined surface 22111. When the cleaning plate 221 is in a static state or a slow rotation state, at least part of the cleaning liquid on the inner cleaning plate 2211 can flow naturally to the middle part of the inner cleaning plate 2211 along the inclined surface 22111 under the guidance of gravity and be discharged through the sewage outlet 2213.

[0085] Referring to FIG. 5, the middle part of the inner cleaning plate 2211 is inclined relative to the outer edge toward the side of the base 210 and forms an inclined surface 22111. The liquid on the surface of the cleaning plate 221 can flow along the inclined surface 22111 to the sewage outlet 2213 under the guidance of the flow guide ribs 223. The inclined surface 22111 of the inner cleaning plate 2211 can provide a certain centripetal force to the rotating water flow. When the cleaning assembly 130 and the cleaning plate 221 rotate relative to each other, the water flow on the inner cleaning plate 2211 can obtain a certain centripetal force through the inclined surface 22111, and cooperate with the centripetal force and guidance provided by the flow guide ribs 223. The liquid flow can further overcome the centrifugal force generated by rotation and flow to the position of the sewage outlet 2213 under the guidance of the centripetal force through the flow guide ribs 223, so as to ensure that the liquid flow can be smoothly discharged.

[0086] In some embodiments, the height difference H of the inclined surface 22111 on the inner cleaning plate 2211 in the axial direction should be appropriate to meet the liquid flow to the sewage outlet 2213. If the height difference H is too large, it may cause the height of the cleaning assembly 220 in the axial direction to be too high, affecting the normal parking of the cleaning equipment 100 on the cleaning base 200. Referring to FIGS. 4 and 6, the above height difference H should generally be controlled within 1 cm.

[0087] Due to the inclined surface 22111 of the inner cleaning plate 2211 and the flow guide ribs 223, the inner cleaning plate 2211 has a good guiding and discharging effect on sewage, can quickly guide the sewage to the sewage outlet 2213 located in the middle part of the inner cleaning plate 2211, and helps to improve the sewage discharge efficiency and cleaning efficiency of the cleaning plate 221. After cleaning, the above inclined surface 22111 helps to guide the liquid remaining on the upper surface of the cleaning plate 221 to flow to the sewage outlet 2213 under the action of gravity and be discharged through the sewage outlet 2213, avoiding the situation that the cleaning plate 221 produces odor due to long-time liquid remaining, and being conducive to improving the cleanliness of the cleaning assembly 130.

[0088] It should be noted that the above-mentioned guide ribs 223 can also interfere with the mop 131 of the cleaning assembly 130, and through the way of scraping and washing the surface of the mop 131, the mop 131 can be cleaned to some extent by the cleaning structure 224, so as to further ensure the cleaning effect of the cleaning assembly 130.

[0089] It can be understood that the cleaning assembly 220 can ensure that the cleaning assembly 130 and the cleaning assembly 220 have sufficient contact area during the forward or reverse rotation of the cleaning assembly 130 relative to the cleaning assembly 220, through the guide ribs 223 and the cleaning structure 224 on the upper surface of the cleaning assembly 220, so as to ensure good cleaning effect; at the same time, it can ensure that the cleaning assembly 220 has a smooth sewage discharge mode, and the sewage generated in the cleaning process can be successfully discharged, so as to ensure good cleaning efficiency. During the cleaning process, the radially arranged guide ribs 223 and cleaning structure 224 can provide uniform and continuous interference fit to the radial direction of the cleaning assembly 130 during the rotation relative to the cleaning assembly 130, and can guide the flow of liquid while providing certain extrusion and scraping to the cleaning assembly 130, so that the cleaning assembly 130 has better cleaning effect.

[0090] In some embodiments, the above-mentioned cleaning plate 221 can be in a whole disc, disc or flat plate structure. In addition to the above-mentioned liquid guide groove 222, a support 22153 is also arranged on the circumferential outer side edge of the cleaning plate 221.

[0091] Specifically, the above-mentioned support 22153 extends outwardly relative to the circumferential side edge of the cleaning plate, so as to support the outer ring cleaning plate 2212 and the inner ring cleaning plate 2211. Please refer to FIG. 5, at least part of the support 22153 is located on the lower surface of the cleaning plate 221 and extends outwardly relative to the circumferential side edge of the cleaning plate 221 along the radial direction of the cleaning plate 221, which helps to enhance the strength of the cleaning plate 221. In addition, the support 22153 can also be connected with the connecting head 22152 on the side of the cleaning plate 221 facing the base 210 and cooperates to form a connecting piece 2215. The connecting piece 2215 is used to realize the transmission connection between the cleaning plate 221 and the driving assembly 230. The above-mentioned connecting piece 2215, the inner ring cleaning plate 2211 and the outer ring cleaning plate 2212 can be an integral structure.

[0092] Please refer to FIG. 5, the end of the connecting piece 2215 away from the driving assembly 230 (i.e. the middle of the connecting piece 2215) forms a discharge port 22151 which can be connected with the sewage discharge port 2213.

[0093] Specifically, the number of the discharge ports 22151 is multiple, and any one of the discharge ports 22151 is formed between two adjacent supports 22153. When the number of the supports 22153 is three, the number of the discharge ports 22151 is also three and is arranged in sequence with the supports 22153. The connecting head 22152 arranged on the side of the cleaning plate 221 facing the base 210 is a hollow structure, one end of which is fixedly connected with each support 22153, and the other end forms a cover-shaped structure for covering the output end of the driving assembly 230. The cover-shaped structure can be fixedly connected with the output end of the driving assembly 230 in a clamping manner, so that the cleaning plate 221 can rotate or stop with the driving of the driving assembly 230.

[0094] Please refer to FIG. 4. In some embodiments, the number of the liquid guide groove 222 is one, and the liquid guide groove 222 is located on the side of a support 22153 away from the base 210. The liquid guide groove 222 and the support 22153 are an integral structure. Of course, it can also be considered that the side of one of the supports 22153 away from the base 210 is provided with the liquid guide groove 222.

[0095] In other embodiments, the number of the liquid guide groove 222 can be two, three, etc., and each liquid guide groove 222 is located on the side of a corresponding support 22153 away from the base 210.

[0096] Correspondingly, one end of the support 22153 in the radial direction points to the discharge port 2213, and the other end points to the outside of the cleaning plate 221 and protrudes outward in the radial direction relative to the cleaning plate 221.

[0097] Specifically, as shown in FIG. 4, the number of the cleaning structures 224 is multiple and is uniformly spaced along the circumferential direction and / or the radial direction of the cleaning plate 221, and at this time, the cleaning structures 224 are located on the side of the supports 22153 away from the base 210. In the direction of the orthographic projection of the cleaning plate 221, the projection of the cleaning structure 224 falls within the projection range of the support 22153.

[0098] This structural arrangement can ensure that the cleaning structure 224 can interfere with the mop 131 relatively uniformly and reliably, so that the cleaning structure 224 and the mop 131 have sufficient contact area and the contact parts are uniformly arranged, to ensure that the cleaning assembly 220 can maintain good cleaning efficiency on each position of the cleaning mop 131.

[0099] Please refer to Fig. 4, the above-mentioned liquid guide groove 222 includes a guide plate 2221 arranged on the upper surface of the cleaning plate 221. The number of the guide plate 2221 is at least two, and the two guide plates 2221 form a through groove for the flow of cleaning liquid, and the cleaning liquid flows from the liquid discharge groove 2101 to the upper surface of the cleaning plate 221 through the through groove. When the guide plate 2221 is arranged, the two guide plates 2221 for forming the same liquid guide groove 222 should be arranged along the radial direction of the cleaning plate 221, or the two guide plates 2221 are parallel to each other.

[0100] Specifically, the above-mentioned radial extension refers to that the two ends of the guide plate 2221 are respectively connected with the inner and outer parts of the radial direction of the cleaning plate 221, and it is not required that the extension direction is necessarily parallel to the radial direction. In some embodiments, the liquid guide groove 222 formed by the guide plate 2221 can be a straight groove extending along the radial direction, or a slant groove extending at a certain angle with the radial direction, or a curved groove with a certain bending angle.

[0101] In some embodiments, in order to ensure that the liquid guide groove 222 has sufficient water guiding effect and further helps the cleaning liquid to be uniformly distributed along the radial direction of the mop 131, at least one guide plate 2221 extends from the outer ring cleaning plate 2212 to above the inner ring cleaning plate 2211 along the surface of the cleaning plate 221, please refer to Fig. 4, at this time the cleaning liquid flows from the upper surface of the outer ring cleaning plate 2212 to the upper surface of the inner ring cleaning plate 2211 along the radial direction of the cleaning plate 221 under the guidance of the guide plate 2221, and can gradually wet the mop 131 from the outside to the inside. When there is relative rotation between the cleaning assembly 130 and the cleaning assembly 220, the cleaning liquid flowing onto the upper surface of the cleaning plate 221 under the guidance of the liquid guide groove 222 can circulate with different areas of the cleaning assembly 130 with the rotation of the cleaning assembly 130, thereby enabling the cleaning assembly 130 to be uniformly wetted in the circumferential direction. The wetted cleaning assembly 130 interferes with the cleaning assembly 220, which can further improve the cleaning effect.

[0102] Specifically, at least one liquid guide groove 222 is arranged on one cleaning plate 221. Of course, the number of liquid guide grooves 222 can also be reasonably adjusted to two, three or even more according to needs. By reasonably setting the number and distribution mode of the liquid guide groove 222, the cleaning liquid can be uniformly and comprehensively distributed on the upper surface of the cleaning plate 221, so that the wetting range of the mop 131 is more comprehensive and uniform. The plurality of liquid guide grooves 222 are distributed on the cleaning plate 221.

[0103] The cleaning liquid flowing out of the drainage groove 2101 can be guided to the upper surface of the cleaning plate 221 by the liquid guide groove 222. When the cleaning assembly 220 is matched with the upper surface of the cleaning plate 221, please refer to FIG. 7, the cleaning liquid on the upper surface of the cleaning plate 221 can wet the cleaning assembly 130. The wet cleaning assembly 130 matched with the cleaning plate 221 can improve the cleaning effect on the cleaning assembly 130.

[0104] The cleaning assembly 220 is installed on the base 210 by the driving assembly 230. When the driving assembly 230 is started, the cleaning assembly 220 can rotate forward or reversely under the driving of the driving assembly 230. When the cleaning assembly 130 is just above the cleaning assembly 220 and at least part of the cleaning assembly 130 acts on the cleaning assembly 220 under the action of gravity, please refer to FIG. 7, at this time, the cleaning assembly 220 rotating forward or reversely can directly act on the surface of the mop 131 of the cleaning assembly 130, and by cooperating with an appropriate amount of cleaning liquid, the cleaning of the mop 131 can be realized by scraping, extruding and other ways on the surface of the mop 131.

[0105] FIG. 8 is a cross-sectional structure schematic view of the cleaning assembly, the cleaning assembly and the drainage groove in FIG. 7, FIG. 9 is a cleaning liquid flow direction schematic view in FIG. 8, and FIG. 10 is a relative position relationship schematic view of the cleaning assembly and the liquid outlet in the cleaning base in the cleaning state provided by the embodiment of the application.

[0106] Please refer to FIG. 3 and FIG. 7, in the cleaning process of the cleaning assembly 130, sufficient cleaning water needs to be provided to wet the mop 131 to ensure the cleaning effect.

[0107] In the prior art, the wetting of the cleaning assembly 130 can be realized by cooperating the liquid outlet on the main body of the cleaning device 100 with the liquid guide channel 132 on the cleaning assembly 130, and the wetting efficiency is low. In order to improve the wetting efficiency of the cleaning assembly 130, please refer to FIG. 7-FIG. 8. The liquid outlet on the main body of the cleaning device 100 is not drawn in the figure.

[0108] Specifically, the above-mentioned cleaning assembly 130 includes the mop 131 which can be wetted.

[0109] In some embodiments, the number of the above-mentioned liquid outlets is at least two, and the liquid guide channel 132 on the cleaning assembly 130 is correspondingly arranged with the liquid outlets. The liquid guide channel 132 can communicate the above-mentioned liquid outlets and the mop 131. In the axial direction of the cleaning assembly 130, the projection of the above-mentioned liquid outlet can fall within the projection range of the liquid guide channel 132.

[0110] In order to make the cleaning liquid have a larger wetting range as much as possible, the mop 131 has a sufficient area to be wetted in the radial direction. In addition to adjusting the liquid guide channel 132 to have a sufficient radial dimension, the relative position between the liquid outlet and the liquid guide channel 132 also needs to be adjusted.

[0111] Referring to FIGS. 8-9, the liquid guide channel 132 has a first edge 1321 and a second edge 1322 arranged oppositely in the radial direction of the cleaning assembly 130, wherein the first edge 1321 is located on the side of the cleaning assembly 130 away from the center in the radial direction, and the second edge 1322 is located on the side of the cleaning assembly 130 close to the center in the radial direction.

[0112] Among the plurality of liquid outlets provided on the main machine of the cleaning device 100, the projection of at least one liquid outlet is adjacent to the projection of the first edge 1321, and the projection of at least one liquid outlet is adjacent to the projection of the second edge 1322. Further, the above-mentioned two liquid outlets can be located on the two sides of the cleaning assembly 130 in the diameter direction respectively. At this time, the cleaning liquid released by the above-mentioned two different liquid outlets has a certain spacing in the radial direction, so that the mop 131 can have a larger wetting range in the radial direction to a certain extent, which helps to improve the wetting efficiency and cleaning effect of the mop 131.

[0113] When the cleaning assembly 130 is parked in the containing space, the projection of the liquid outlet can also fall within the projection range of the inner ring cleaning plate 2211 and the projection range of the outer ring cleaning plate 2212 in the axial direction of the cleaning assembly 220. Referring to FIGS. 9-10, the projections of at least two liquid outlets fall on the inner and outer sides of the outer contour of the inner ring cleaning plate 2211, and the positions of the circular dots in FIG. 10 are the positions of the projections of the liquid outlets on the cleaning plate 221. Of course, with the relative rotation between the cleaning assembly 130 and the cleaning assembly 220, the position of the projection of the liquid outlet on the cleaning plate 221 can move in a certain area relative to the cleaning plate 221 along the rotating radius of the position of the circular dot, but the spacing of the two liquid outlets in the radial direction can always remain consistent.

[0114] Referring to FIG. 9, the cleaning liquid can flow to the cleaning assembly 130 through the liquid outlet and the liquid discharge groove 2101 respectively, so that the mop 131 of the cleaning assembly 130 can fully contact the cleaning liquid and be wetted in the radial direction. On this basis, combined with the bidirectional rotation cleaning between the cleaning assembly 130 and the cleaning assembly 220, effective cleaning of the cleaning assembly 130 can be achieved, and the cleaning effect can be optimized.

[0115] Please refer to FIG. 10, the cleaning liquid provided by the liquid outlet above the outer cleaning plate 2212 can supplement the outer area of the mop 131 during the cleaning process, and the sewage generated after the cleaning process can be thrown out by the outer cleaning plate 2212 under the centrifugal force; the cleaning liquid provided by the liquid outlet above the inner cleaning plate 2211 can supplement the inner area of the mop 131 during the cleaning process, and the supplemented cleaning liquid can be gathered in the middle of the inner cleaning plate 2211 under the guidance of the flow guide rib 223 and / or the action of gravity, and then discharged from the sewage outlet 2213 after completing the cleaning of the inner area of the mop 131. Of course, in the cleaning state that the cleaning plate 221 remains stationary relative to the base 210, the above-mentioned part of the cleaning liquid on the inner cleaning plate 2211 can be discharged from the sewage outlet 2213 under the guidance of gravity, or can flow to the outer cleaning plate 2212 under the action of centrifugal force due to the rotation of the cleaning assembly 130.

[0116] The cleaning liquid discharged through the above-mentioned liquid outlet and the liquid discharge groove 2101 can respectively wet the inner and outer circles of the mop 131 in the radial direction, and the wet mop 131 can interfere with the cleaning assembly 220 to improve the cleaning effect.

[0117] During the cleaning process of the cleaning assembly 130, the mop 131 of the cleaning assembly 130 interferes with the cleaning structure 224 on the upper surface of the cleaning plate 221, and there is relative rotation between the cleaning assembly 130 and the cleaning assembly 220. When the cleaning assembly 220 rotates to the position that the liquid guide groove 222 is opposite to the liquid discharge groove 2101, the cleaning liquid at the liquid discharge groove 2101 can flow to the upper surface of the cleaning plate 221 through the liquid guide groove 222, and then wet the mop 131 of the cleaning assembly 130 smoothly and uniformly along with the relative rotation between the mop 131 of the cleaning assembly 130 and the cleaning plate 221.

[0118] It can be understood that during the cleaning process of the cleaning assembly 130, the cleaning liquid can flow to the cleaning assembly 130 through the liquid outlet and / or the liquid discharge groove 2101 according to the cleaning needs. Since the cleaning assembly 220 can rotate bidirectionally relative to the cleaning assembly 130 and clean the cleaning assembly 130 in this process, different or the same water supplementing methods can be used according to the different relative rotation directions between the cleaning assembly 130 and the cleaning assembly 220 when the cleaning assembly 130 is cleaned.

[0119] In some cleaning processes, the drain groove 2101 and the liquid outlet can be started at the same time to wet the mop 131 of the cleaning assembly 130; in other cleaning processes, only the drain groove 2101 can be used to discharge cleaning liquid and wet the mop 131 when the cleaning assembly 130 rotates clockwise relative to the cleaning plate 221 (of course, the cleaning plate 221 can be kept in any one of the three states of static, low-speed counterclockwise rotation, or low-speed clockwise rotation or switched between several states as needed, wherein the low-speed clockwise rotation refers to the clockwise rotation speed of the cleaning assembly 220 being less than that of the cleaning assembly 130); the liquid outlet can be used to wet the mop 131 when the cleaning assembly 220 rotates clockwise relative to the cleaning assembly 130 (of course, the cleaning assembly 130 can be kept in any one of the three states of static, low-speed counterclockwise rotation, or low-speed clockwise rotation or switched between several states as needed, wherein the low-speed clockwise rotation refers to the clockwise rotation speed of the cleaning assembly 220 being less than that of the cleaning assembly 130).

[0120] Specifically, in a certain cleaning process, the cleaning assembly 130 rotates forward, the cleaning assembly 220 is in a non-rotating state, and the liquid guide groove 222 is opposite to the drain groove 2101. The cleaning liquid in the drain groove 2101 flows to the cleaning plate 221 through the liquid guide groove 222 and wets the mop 131. At this time, the cleaning assembly 130 can also wet the middle region of the mop 131 through the liquid outlet on the main machine as needed.

[0121] In the forward cleaning process, the cleaning assembly 220 can be in a non-rotating state only when the cleaning liquid needs to be supplemented, and can be kept in any one of the non-rotating, reverse rotating, and low-speed forward rotating states at other times, wherein the low-speed forward rotating refers to the forward rotation speed of the cleaning assembly 220 being less than that of the cleaning assembly 130.

[0122] In the reverse cleaning process, the cleaning assembly 130 can be kept in a non-rotating state, and the cleaning assembly 220 rotates forward under the driving of the driving assembly 230. The cleaning liquid at the liquid outlet can flow to the mop 131 through the liquid guide channel 132 and wet the mop 131. At this time, the liquid outlet is the main water source. The drain groove 2101 is kept in a non-water discharging state, of course, the drain groove 2101 can be switched between the non-water discharging and water discharging states as needed.

[0123] Of course, there are other water adding methods, for example, the drain groove 2101 and the liquid outlet are started in a pulse mode or alternately started to wet the mop 131.

[0124] In some embodiments, during the cleaning process of the cleaning assembly 130, the relative rotation speed and the relative rotation direction between the cleaning assembly 130 and the washing assembly 220 can be adjusted according to the actual situation during the different processes of wetting, cleaning and spinning of the mop 131 during the cleaning process.

[0125] FIG. 11 is a structural schematic diagram of a driving assembly in a cleaning base station provided by an embodiment of the present application. Referring to FIGS. 2 and 11, in order to ensure that the driving assembly 230 can continuously and stably output actions, in some embodiments, the driving assembly 230 is provided to include a driving motor 231 and a transmission gear 232 set, the transmission gear 232 set including a plurality of gears 232 that are sequentially engaged, one of the gears 232 being in transmission connection with the driving motor 231, and another gear 232 being in transmission connection with the washing assembly 220, the driving assembly 230 driving the washing assembly 220 to rotate through the transmission gear 232 set. The number and specific structure of the gears 232 can be adjusted and arranged according to actual needs, as long as the transmission function of the transmission gear 232 set can be ensured.

[0126] Specifically, the washing assembly 220 is located in the axial direction of the gears 232 and is in transmission connection with the corresponding gears 232. The power output by the driving motor 231 can be transmitted to the washing assembly 220 through the transmission gear 232 set, so that the washing assembly 220 can be driven by the driving motor 231 to rotate in the forward direction or in the reverse direction. When the output power direction of the driving motor 231 is switched, the rotation direction of the washing assembly 220 is also switched synchronously.

[0127] When the cleaning assembly 130 is located above the washing assembly 220 and cooperates with the washing assembly 220, the rotating washing assembly 220 can clean the cleaning assembly 130 in two directions, achieving efficient cleaning of the cleaning assembly 130.

[0128] In some embodiments, since the number of the washing assemblies 220 is two, the driving motor 231 can drive the two washing assemblies 220 to rotate simultaneously when it is started. The two washing assemblies 220 can rotate towards the same direction or can rotate towards different directions respectively.

[0129] The transmission structure composed of the gears 232 not only serves to realize force transmission, but also can help to reduce the overall height of the base station 210 by virtue of the distribution manner of being arranged side by side, so as to facilitate the cleaning device 100 to walk to above the washing assembly 220 conveniently and smoothly.

[0130] When the cleaning assembly 130 needs to be cleaned, the driving motor 231 can be driven to drive the washing assembly 220 to rotate in the forward direction or in the reverse direction relative to the cleaning assembly 130, under the premise that the cleaning assembly 130 has been positioned, so as to realize bidirectional cleaning of the cleaning assembly 130.

[0131] It can be understood that the cleaning base station 200 provided by the embodiment of the present application can make the cleaning assembly 220 and the cleaning assembly 130 generate bidirectional rotation by driving the cleaning assembly 220 to rotate relative to the cleaning assembly 130, and the guide ribs 223 and the cleaning structure 224 and other structures arranged on the cleaning assembly 220 can realize bidirectional efficient cleaning of the cleaning assembly 130 while rotating. Meanwhile, cooperating with the new water guiding mode, the cleaning assembly 130 can be fully covered, wetted and cleaned in the radial direction by cooperating with the helically arranged guide ribs 223 and the inclined surface 22111, so as to effectively improve the cleaning effect and cleaning efficiency of the cleaning assembly 220 on the cleaning assembly 130, and shorten the cleaning time.

[0132] FIG. 12 is a partial structure schematic diagram of a cleaning system provided by the embodiment of the present application, FIG. 13 is an exploded view of FIG. 12, FIG. 14 is a partial structure schematic diagram of a cleaning device in FIG. 12, and FIG. 15 is a connection schematic diagram of a motion mechanism and a cleaning assembly in FIG. 14.

[0133] Please refer to FIGS. 12-13, the embodiment of the present application provides a cleaning system 1000, which comprises a cleaning device 100 and a cleaning base station 200, wherein the cleaning base station 200 is the cleaning base station 200 described above, and the cleaning device 100 is a structure with a cleaning assembly 130, and in addition, the cleaning device 100 is further provided with the liquid outlet described above, which will not be described here.

[0134] When the cleaning device 100 is in standby state or cleaning state, it can be seen that the cleaning assembly 130 in the cleaning device 100 is docked on the cleaning base station 200, and the cleaning assembly 130 is just located above the cleaning assembly 220.

[0135] In some embodiments, the cleaning device 100 can have two cleaning assemblies 130 arranged side by side, please refer to FIG. 13, at this time, the number of cleaning assemblies 130 that need to be cleaned is two, and accordingly, the number of cleaning assemblies 220 should also be two.

[0136] Please refer to FIG. 14, the cleaning device 100 further comprises a motion mechanism 120 in transmission connection with the cleaning assembly 130. When the host is started, the cleaning assembly 130 can move with the movement of the host under the driving of the motion mechanism 120, in addition, the cleaning assembly 130 can also rotate relative to the host and synchronous lifting action under the driving of the motion mechanism 120, so as to realize the mopping function. According to the cleaning needs of the cleaning assembly 130 and the cleaning command executed by the cleaning device 100, the motion mechanism 120 can drive the cleaning assembly 130 to perform lifting and rotating actions, so that it is in different states, executes different commands, and meets different cleaning needs.

[0137] In some embodiments, referring to FIGS. 14-15, the above-mentioned moving mechanism 120 can be an electric motor, and the cleaning assembly 130 can be a cleaning tool with a mop 131 mounted thereon. When the electric motor is started, the cleaning assembly 130 can rotate under the driving of the electric motor.

[0138] In order to further realize the lifting action of the cleaning assembly 130 relative to the main machine and better cooperate the cleaning assembly 130 with the cleaning base 210 with the bidirectional rotating cleaning assembly 220, the cleaning device 100 further comprises a transmission mechanism 110 for connecting the cleaning assembly 130 and the moving mechanism.

[0139] FIG. 16 is a connection diagram of the transmission mechanism in FIG. 14, FIG. 17 is a sectional view of FIG. 16, FIG. 18 is a structural diagram of a transmission shaft in FIG. 16, FIG. 19 is another structural diagram of the transmission shaft in FIG. 16, FIG. 20 is a structural diagram of a lifting guide cylinder in FIG. 16, and FIG. 21 is a distribution diagram of a self-locking assembly in FIG. 16.

[0140] Referring to FIGS. 16, 17 and 21, the above-mentioned transmission mechanism 110 connected with the cleaning assembly 130 is used to connect the cleaning assembly 130 and the moving mechanism 120 to realize the transmission connection between the cleaning assembly 130 and the moving mechanism 120.

[0141] Referring to FIG. 17, the transmission mechanism 110 mainly comprises a self-locking assembly 111 and a transmission shaft 112. The self-locking assembly 111 has an input end 1111 and an output end 1112. The input end 1111 is used to connect the moving mechanism 120, and the output end 1112 is used to connect the transmission shaft 112. The transmission shaft 112 is connected with the output end 1112 of the self-locking assembly 111 and the cleaning assembly 130 at two ends in the axial direction, respectively, and is used to transmit the rotating motion output by the output end 1112 to the cleaning assembly 130. Since the transmission shaft 112 is connected with the self-locking assembly 111 and the cleaning assembly 130 at the same time, the rotating of the cleaning assembly 130 under the driving of the power other than the transmission shaft 112 can be effectively prevented, so as to achieve the self-locking effect of the transmission mechanism 110.

[0142] Please refer to FIG. 18-19, the transmission shaft 112 is provided with a first transmission joint 1121 and a second transmission joint 1122 at both ends of the shaft in the axial direction, and the axes of the first transmission joint 1121 and the second transmission joint 1122 are located on the same straight line. As shown in FIG. 17-18, the transmission shaft 112 is connected with the self-locking assembly 111 through the first transmission joint 1121, and is connected with the cleaning assembly 130 through the second transmission joint 1122, and the axes of the first transmission joint 1121 and the second transmission joint 1122 are located on the same straight line. When the cleaning assembly 130 is connected with the transmission shaft 112, the cleaning assembly 130 can rotate clockwise or counterclockwise around the axis under the driving of the force transmitted from the self-locking assembly 111 through the transmission shaft 112; and when the cleaning assembly 130 is driven by an external force not transmitted by the transmission shaft 112, the transmission shaft 112 connected with the cleaning assembly 130 can prevent the cleaning assembly 130 from rotating under the locking action provided by the self-locking assembly 111, so as to achieve the rotation control of the cleaning assembly 130 and ensure that the cleaning assembly 130 will not rotate relative to the transmission shaft 112 under the driving of the external force.

[0143] In the related art, the cleaning assembly 130 is cleaned by generating relative rotation between the cleaning assembly 130 and the corresponding cleaning assembly 220. In the process of rotation, the cleaning assembly 220 removes the impurities and dirt on the surface of the cleaning assembly 130 by scraping, extruding or other ways, so as to achieve the purpose of cleaning the cleaning assembly 130. Due to the transmission structure between the cleaning assembly 130 and the movement mechanism 120, the rotating action and the lifting action of the cleaning assembly 130 are coupled, so that the cleaning assembly 130 in the prior art can only rotate relative to the cleaning assembly 220 in a certain fixed direction, and the cleaning of the cleaning assembly 130 is achieved in the process of rotation.

[0144] In the present application, since the cleaning assembly 130 can only rotate under the driving of the transmission shaft 112, when the cleaning assembly 220 rotates relative to the cleaning assembly 130 under the driving of the external force and cleans it, the cleaning assembly 130 will not rotate with the action of the cleaning assembly 220 under the action of the friction. That is, under the locking of the transmission mechanism 110, the cleaning assembly 130 will not be affected by the friction generated by the rotation of the cleaning assembly 220 and will not produce lifting action due to rotation. At this time, the relative rotation between the cleaning assembly 130 and the cleaning assembly 220 in two different directions can be easily generated by adjusting the rotating direction and rotating speed of the cleaning assembly 130 and the cleaning assembly 220, so as to achieve the purpose of bidirectional cleaning of the cleaning assembly 130. In addition, by adjusting the rotating direction of the cleaning assembly 220 relative to the cleaning assembly 130, the cleaning assembly 130 can be cleaned in two directions, which greatly improves the cleaning efficiency of the cleaning assembly 130.

[0145] The cleaning assembly 130 can be an assembly with a mopping function. When the cleaning assembly 130 is cleaned, the cleaning assembly 130 is located above the cleaning assembly 220. At this time, the cleaning assembly 130 is installed with a mop 131 for mopping and is in contact with the cleaning assembly 220. The cleaning assembly 220 cleans the mop 131 by scraping, pressing, or other methods on the surface of the mop 131.

[0146] The self-locking assembly 111 can effectively prevent reverse movement and ensure that the transmission shaft 112 or other loads do not move in the opposite direction due to gravity, external loads, or other factors in the absence of driving force.

[0147] Please refer to FIGS. 16-17. In some embodiments, the self-locking assembly 111 can be composed of a worm gear structure with a self-locking function. The input end 1111 is located in the worm gear structure. The power output by the movement mechanism 120 can be input into the self-locking assembly 111 through the worm, and then input into the output end 1112 downstream, such as the gear 232 provided with a gear ring on the outer periphery or other structures known in the related art.

[0148] In other embodiments, the self-locking assembly 111 can also be a lead screw nut structure, a conical friction self-locking structure, and an overrunning clutch.

[0149] In order to facilitate the connection of the transmission shaft 112 and the output end 1112, please refer to FIGS. 18 and 21. One end of the transmission shaft 112 in the axial direction is provided with a first transmission joint 1121. The transmission shaft 112 is connected to the output end 1112 of the self-locking assembly 111 through the first transmission joint 1121. At this time, the output end 1112 of the self-locking assembly 111 can provide stable torque transmission to the outside through the transmission shaft 112.

[0150] In some embodiments, in order to facilitate the transmission of the transmission shaft 112 and the output end 1112, they can be connected through meshing structures, or at least one of the first transmission joint 1121 and the output end 1112 is provided with a first protrusion, and the other is provided with a first recess. When the first transmission joint 1121 is inserted into the output end 1112, the first protrusion can be embedded in the first recess, and the transmission of the transmission shaft 112 and the output end 1112 is achieved.

[0151] In some embodiments, the number of the above-mentioned first protrusions and first recesses can be several. When the number of the first protrusions and the first recesses is multiple, the structure of the transmission shaft 112 with the first transmission joint 1121 is shown in FIG. 18, and the structure of the output end 1112 with the first protrusion and / or the first recess is shown in FIG. 21.

[0152] Please refer to FIG. 18 and FIG. 21, the first transmission joint 1121 in the transmission shaft 112 is a columnar structure, and a plurality of first protrusions and first recesses are distributed on the outer wall in the circumferential direction. The output end 1112 of the self-locking assembly 111 is a gear 232-shaped structure with a first recess and a first protrusion in the middle. When the transmission shaft 112 is inserted into the self-locking assembly 111, the first transmission joint 1121 and the output end 1112 can be conveniently positioned and connected by the cooperation of the first protrusions and the first recesses, so that the transmission shaft 112 can rotate synchronously with the output end 1112. Please refer to FIG. 18 and FIG. 21, the first protrusions and the first recesses of the first transmission joint 1121 are arranged on the outer wall in the circumferential direction, and the first transmission joint 1121 has a prismatic structure with a projection shape similar to a "cross" in the axial direction. The first protrusions and the first recesses of the output end 1112 are arranged on the inner wall in the circumferential direction, and the structure of the output end 1112 in contact with the first transmission joint 1121 has a projection shape matching the projection shape of the first transmission joint 1121 in the axial direction.

[0153] In order to facilitate the connection between the transmission shaft 112 and the output end 1112, please refer to FIG. 17 and FIG. 19, the other end of the transmission shaft 112 in the axial direction is provided with a second transmission joint 1122, and the transmission shaft 112 is connected with the cleaning assembly 130 through the second transmission joint 1122.

[0154] In some embodiments, in order to facilitate the transmission between the transmission shaft 112 and the cleaning assembly 130, the two can be connected through the meshing structure, or the second transmission joint 1122 and the cleaning assembly 130 are provided with a second protrusion and a second recess respectively. When the second transmission joint 1122 is inserted into the output end 1112, the second protrusion can be embedded in the second recess, and the transmission between the transmission shaft 112 and the cleaning assembly 130 is achieved, as shown in FIG. 17.

[0155] In some embodiments, the number of the second protrusions and the second recesses can be several.

[0156] In some embodiments, a hollow prism-shaped insertion hole can be formed in the second transmission joint 1122 of the transmission shaft 112, and a matching columnar structure can be provided on the cleaning assembly 130. The columnar structure is similar to a hexagonal prism, and the side wall thereof is formed by a plurality of planes and curved surfaces arranged in sequence. When the columnar structure of the cleaning assembly 130 is inserted into the second transmission joint 1122, the second transmission joint 1122 and the cleaning assembly 130 can be conveniently connected in transmission. Of course, the cleaning assembly 130 can also be provided with other structures for firmly connecting with the second transmission joint 1122, such as a magnetic structure with magnetic force.

[0157] After the cleaning assembly 130 is connected with the second transmission joint 1122 of the transmission shaft 112, the cleaning assembly 130 can rotate synchronously with the rotation of the second transmission joint 1122. The second protrusion and the second groove structure of the second transmission joint 1122 are arranged on the circumferential outer wall, as shown in FIG. 19. At this time, the second transmission joint 1122 presents a hexagonal prism-shaped insertion hole, and the columnar structure of the cleaning assembly 130 is a matching hexagonal prism structure.

[0158] The transmission shaft 112 is connected with the self-locking assembly 111 through the first transmission joint 1121 and connected with the cleaning assembly 130 through the second transmission joint 1122. The transmission shaft 112 can receive the torque transmitted by the self-locking assembly 111 through the first transmission joint 1121 and provide stable torque transmission to the outside through the second transmission joint 1122. The transmission shaft 112 can reduce the bounce and swing during transmission and ensure the stability and accuracy of the output force. The prism-shaped transmission shaft 112 structure also helps to realize accurate axial and circumferential positioning, avoiding the deviation and misplacement of the transmission shaft 112 during rotation. At the same time, the first transmission joint 1121 similar to a prism shape can also bear a large load and torque, which can help to optimize the transmission mechanism 110 and make it more durable, prolonging the service life of the transmission mechanism 110.

[0159] When the main body is started, the cleaning assembly 130 can be moved with the movement of the main body under the driving of the movement mechanism 120 and the transmission mechanism 110 to realize the mopping function. The movement mechanism 120 can directly drive the cleaning assembly 130 to move through the transmission mechanism 110, for example, the movement mechanism 120 can drive the cleaning assembly 130 to rotate and / or lift relative to the main body. According to the cleaning needs of the area to be cleaned and the cleaning command executed by the cleaning device 100, the movement mechanism 120 can drive the cleaning assembly 130 to lift and rotate to meet different cleaning needs.

[0160] In order to enable the cleaning assembly 130 to also perform a lifting action under the driving of the transmission shaft 112, please refer to FIG. 17 and FIG. 20, in some embodiments, the transmission shaft 112 is further sleeved with a lifting guide cylinder 113, and the inner wall of the lifting guide cylinder 113 is provided with a guide block 1131 at the end away from the first transmission joint 1121 of the transmission shaft 112. The outer peripheral side wall of the end of the transmission shaft 112 used for connecting the cleaning assembly 130 is further provided with external threads 1123. When the lifting guide cylinder 113 is sleeved on the transmission shaft 112 through the cooperation of the guide block 1131 and the external threads 1123, the above-mentioned guide block 1131 is slidingly embedded between the external threads 1123 and can slide relative to the external threads 1123 with the rotation of the transmission shaft 112, thereby realizing the lifting action relative to the transmission shaft 112.

[0161] Please refer to FIG. 17, the lifting guide cylinder 113 can be limitedly installed relative to the main body through a limiting ring or the like structure, the limiting ring is fixed with the main body, and a strong friction force is generated between the limiting ring and the lifting guide cylinder 113 through interference fit, so that the lifting guide cylinder 113 can keep relatively static with the main body. Therefore, when the transmission shaft 112 rotates, the transmission shaft 112 can perform a lifting action relative to the lifting guide cylinder 113 under the guidance of the guide block 1131, thereby realizing the effect of driving the cleaning assembly 130 to perform a lifting action and a rotating action.

[0162] Please refer to FIG. 20, the inner side wall of the lifting guide cylinder 113 is provided with three guide blocks 1131. In the process of rotating the transmission shaft 112, each guide block 1131 respectively acts with the threads of the transmission shaft 112 and drives the transmission shaft 112 to lift. When the guide block 1131 slides to the end of the external threads 1123, at this time, the transmission shaft 112 is continuously rotated in the same direction, the lifting guide cylinder 113 can overcome the friction force provided by the limiting ring under the rotating action of the transmission shaft 112, and then synchronously rotate under the driving of the transmission shaft 112.

[0163] Please refer to FIG. 18 and FIG. 19, in order to better protect the lifting guide cylinder 113 and avoid the position where the lifting guide cylinder 113 is located from being polluted by the environment or impurities entering, the second transmission joint 1122 end of the above-mentioned transmission shaft 112 extends outward to form a flange 1124, the radial outer edge of the flange 1124 can extend in the direction of the first transmission joint 1121 along the axial direction, thereby forming a protective cylinder 1125, and the inner side wall of the protective cylinder 1125 and the outer side wall of the second transmission joint 1122 have a space for the lifting guide cylinder 113 to insert. The lifting guide cylinder 113 is inserted between the protective cylinder 1125 and the second transmission joint 1122 and connected with the transmission shaft 112 through the guide block 1131.

[0164] It can be understood that the transmission shaft 112 can be driven to rotate only by the rotation driving force output by the self-locking assembly 111, and then it is ensured that the cleaning assembly 130 mounted on the transmission shaft 112 can also be driven to rotate only by the self-locking assembly 111. When the cleaning assembly 130 connected with the transmission shaft 112 is driven to rotate by the rotation driving force output by the non-self-locking assembly 111, the transmission shaft 112 can prevent the cleaning assembly 130 from rotating under the locking effect provided by the self-locking assembly 111, so as to ensure that the cleaning assembly 130 connected with the transmission shaft 112 will not rotate under the driving of external force. When the transmission mechanism 110 is applied to the cleaning device 100, the transmission mechanism 110 can prevent the cleaning assembly 130 and the transmission shaft 112 from rotating under the action of other external forces by using the self-locking assembly 111, so as to ensure that the cleaning assembly 130 will not rotate randomly under the friction of the cleaning assembly 220 when the cleaning assembly 220 acts on the cleaning assembly 130, and ensure that the cleaning assembly 220 can be forward and reverse rotated relative to the cleaning assembly 130, and bidirectional cleaning of the cleaning assembly 130 is realized, so as to improve the cleaning effect and cleaning efficiency of the cleaning assembly 130.

[0165] In the cleaning system 1000, the cleaning assembly 130 on the cleaning device 100 is driven to rotate by the movement mechanism 120, and the cleaning assembly 220 on the cleaning base station 200 is driven to rotate by the driving assembly 230. When the cleaning assembly 130 needs to be cleaned, the cleaning device 100 is controlled to move to the cleaning base station 200 and dock in place, and then the cleaning assembly 130 is sequentially subjected to forward cleaning and reverse cleaning in a set cleaning order.

[0166] In the forward cleaning process, it is ensured that the cleaning assembly 130 can rotate forward (i.e., clockwise) relative to the cleaning assembly 220, and at this time the cleaning assembly 220 can directly act on the mop 131 of the cleaning assembly 130 and clean it forward.

[0167] When the forward cleaning of the cleaning assembly 130 is performed, the cleaning assembly 130 can be driven to rotate forward by the movement mechanism 120, and the cleaning assembly 220 on the base 210 can be in any one of the states of not rotating, rotating reversely, and rotating forward at a low speed, wherein the forward rotation of the cleaning assembly 220 at a low speed refers to that the forward rotation speed of the cleaning assembly 220 is less than the forward rotation speed of the cleaning assembly 130.

[0168] Of course, when the forward cleaning of the cleaning assembly 130 is performed, the driving assembly 230 can also drive the cleaning assembly 220 to rotate reversely, and the cleaning assembly 130 on the cleaning device 100 can be in a state of not rotating.

[0169] When the reverse cleaning operation of the cleaning assembly 130 is performed, the driving assembly 230 can drive the cleaning assembly 220 to rotate forward, and the cleaning assembly 130 on the cleaning device 100 can be kept in any state of non-rotation, reverse rotation and low-speed forward rotation, wherein the low-speed forward rotation refers to that the forward rotation speed of the cleaning assembly 130 is less than the forward rotation speed of the cleaning assembly 220.

[0170] During the cleaning process, the greater the relative speed difference between the cleaning assembly 130 and the cleaning assembly 220, the better the cleaning effect. It should be noted that since the cleaning assembly 130 rises relative to the base 210 when rotating reversely, the reverse rotation time of the cleaning assembly 130 is reduced as much as possible during the cleaning process of the cleaning assembly 130, or the cleaning assembly 130 is driven to rotate reversely only after the cleaning process is completed.

[0171] Compared with the conventional cleaning process of the cleaning assembly 130, the cleaning assembly 130 described above can be self-locked through the transmission mechanism 110 when receiving the rotating force provided by the cleaning assembly 220, so as to ensure that the cleaning assembly 130 will not rotate and rise under stress during the reverse rotation of the cleaning assembly 220 relative to the cleaning assembly 130. This structure can ensure that the cleaning assembly 130 always maintains the extrusion force on the cleaning assembly 220, so as to ensure that the cleaning assembly 130 and the cleaning assembly 220 have sufficient friction and mutual extrusion force, thereby ensuring that the cleaning assembly 220 can exert a better cleaning effect on the cleaning assembly 130.

[0172] When the two cleaning assemblies 130 arranged side by side are cleaned, they can be adjusted to rotate synchronously in the same direction or to rotate in different directions according to actual needs, and at this time, the driving assembly 230 on the base 210 only needs to be correspondingly adjusted to ensure that the cleaning assembly 220 can normally realize its cleaning function.

[0173] It can be understood that the technical scheme provided by the embodiment of the present application can utilize the cleaning assembly 130 connected through the transmission mechanism 110, cooperate with the cleaning assembly 220 which can be independently driven, realize the bidirectional cleaning of the cleaning assembly 130, and optimize the cleaning quality of the cleaning assembly 130, shorten the cleaning time and improve the cleaning efficiency by adjusting the relative rotation speed and the relative rotation direction between the two.

[0174] Compared with the prior art, the present application at least has the following beneficial effects:

[0175] The cleaning base station provided by the embodiments of the present application can improve the cleaning effect of the cleaning assembly to some extent by adjusting the structure of the cleaning assembly, guiding the flow direction of the liquid by the flow guide ribs, and improving the problem that the cleaning effect is different between different areas of the cleaning assembly during cleaning. Under the driving of the driving structure, the flow guide ribs can rotate and guide the flow of the cleaning liquid to the drain, and in this process, the cleaning liquid can fully contact the middle part of the cleaning assembly, so that the liquid flow can better clean the middle part of the mop to improve the cleaning effect of the middle part of the cleaning assembly, which helps to improve the overall cleaning uniformity of the cleaning assembly and improve the cleaning effect of the cleaning assembly. The driving structure can also drive the cleaning assembly to rotate forward or backward, realize bidirectional cleaning of the cleaning assembly by adjusting the relative rotation speed and direction between the cleaning assembly and the cleaning assembly, overcome the defect that the cleaning effect of the traditional cleaning equipment is poor due to the limited cleaning direction of the cleaning assembly, optimize and improve the cleaning effect of the cleaning assembly to some extent, and help to improve the cleaning efficiency of the cleaning assembly and shorten the cleaning time.

[0176] The cleaning system provided by the embodiments of the present application includes the above-mentioned cleaning base station, so the cleaning system at least includes the beneficial effects of any one or several of the above-mentioned cleaning base stations, which will not be repeated here. On the other hand, the technical solution can not only cooperate with the cleaning equipment to realize bidirectional cleaning of the cleaning assembly, but also provide a new bidirectional water guiding method by using the liquid outlet on the cleaning equipment and the liquid discharge groove on the cleaning base station respectively, guide the cleaning liquid to flow along the radial direction of the mop by the flow guide ribs and other structures provided on the cleaning plate of the cleaning assembly, realize radial full coverage of the mop, ensure that each area in the radial direction of the mop can be thoroughly cleaned, improve the cleaning effect of the mop, and on this basis, cooperate with the bidirectional cleaning of the cleaning assembly to fundamentally improve the cleaning effect of the cleaning assembly.

[0177] It can be understood that the cleaning system 1000 provided by the embodiments of the present application comprises the cleaning base station 200 described above, and therefore the cleaning system 1000 at least comprises the beneficial effects of any one or several of the cleaning base stations 200 described above, which will not be repeated here. In another aspect, the cleaning system 1000 can also effectively avoid the defect that the cleaning assembly 130 is lifted upward and separated from the cleaning assembly 220 during reverse cleaning, and the transmission mechanism 110 with self-locking power supply is used to lock the cleaning assembly 130, so that the cleaning assembly 130 cooperates with the cleaning assembly 220 to realize bidirectional and rapid cleaning. In another aspect, the cleaning system 1000 can provide a new water diversion method by using the liquid outlets distributed on the cleaning device 100 and the liquid discharge grooves 2101 on the cleaning base station 200, and can guide the cleaning liquid to fully cover the mop 131 in the radial direction by cooperating with the guide ribs 223 and other structures on the cleaning assembly 220, so as to ensure that each area of the mop 131 in the radial direction can be thoroughly cleaned, improve the cleaning effect of the mop 131, and on this basis, cooperate with the bidirectional cleaning of the cleaning assembly 130, so as to fundamentally improve the cleaning effect of the cleaning assembly 130. The above description of each embodiment tends to emphasize the differences between each embodiment, and the same or similar parts can be referred to each other, and will not be repeated here for the sake of brevity.

[0178] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
