[0118] According to the specific embodiments of the present disclosure, the present disclosure further provides a cleaning system comprising the base station and the cleaning robot as described in any one of the above embodiments.

[0119] Compared with the prior art, the base station for the cleaning robot in the present disclosure has the following technical effects: the second cleaning assembly is arranged on the base and located outside the projection range of the containing cavity on the base, so that the second cleaning assembly can clean the second cleaning cloth of the cleaning robot in a second movement mode; and when performing a cleaning task, the first cleaning assembly cleans the first cleaning cloth in a first movement mode, the movement frequency of the reciprocating linear motion is M, the second cleaning assembly cleans the second cleaning cloth in a second movement mode, the rotation frequency of the second cleaning cloth is N, N is a non-integer multiple of M, and the rotation speed of the second cleaning cloth is 160-260 rpm. The cleaning processes of the first cleaning assembly and the second cleaning assembly can be effectively balanced, and the first cleaning cloth and the second cleaning cloth can be efficiently cleaned.

[0120] Since the water amount in the right washing tank of the first cleaning assembly changes periodically, and the drainage from the washing tank when the second cleaning assembly rotates discontinuously also changes periodically, when the drainage frequency N of the second cleaning assembly is an integer multiple of the movement frequency M of the first cleaning assembly in a unit time T, for example, the drainage frequency N of the second cleaning assembly is an odd multiple of the movement frequency M of the first cleaning assembly, for example, N is 5 and M is 1, then the drainage peak of the second cleaning assembly must meet the peak of the water amount in the right washing tank of the first cleaning assembly, thereby causing the sewage in the sewage tank to flow back into the second cleaning assembly, or even overflow the base. Therefore, in order to avoid the occurrence of this accident, when controlling the rotation of the second cleaning cloth, the drainage frequency N of the second cleaning assembly needs to be set as a non-integer multiple of the movement frequency M of the first cleaning assembly, so that in a long enough cleaning process of the second cleaning cloth and the first cleaning cloth, the drainage peak of the second cleaning assembly will not repeatedly meet the peak of the water amount in the right washing tank of the first cleaning assembly, thereby possibly avoiding the occurrence of such a leakage event.

[0121] In addition, in the rotation cleaning of the second cleaning cloth, in combination with the relationship diagram of the stain cleaning rate / second cleaning cloth life and the rotation speed of the second cleaning cloth, the rotation speed of the second cleaning cloth is 160-260 rpm, and the stain cleaning rate is optimal. When the rotation speed of the second cleaning cloth reaches 160 rpm, the stain cleaning rate will be significantly improved from about 50% to about 70%, which can already meet the cleaning of the second cleaning cloth. With further improvement of the rotation speed, when the rotation speed of the second cleaning cloth reaches 260 rpm, the cleaning rate of the second cleaning cloth is basically close to 95%, which almost completely cleans the stains on the second cleaning cloth. When the rotation speed of the second cleaning cloth is further increased and is greater than 260 rpm, the stain cleaning rate will also basically remain around the corresponding stain cleaning rate. In addition, the power consumption and noise will also increase significantly. Therefore, the rotation speed of the second cleaning cloth is maintained at 160-260 rpm, which can effectively clean the stains on the second cleaning cloth.

[0122] In combination with the experimental given stain cleaning rate / second cleaning cloth life and second cleaning cloth speed relationship diagram, further analysis of the second cleaning cloth life and second cleaning cloth speed relationship, the second cleaning cloth has a basic stable service life at low speed, when the second cleaning cloth speed reaches 160 rpm, the service life of the second cleaning cloth begins to decline steadily, and when the brush speed exceeds 260 rpm, the service life of the second cleaning cloth decreases significantly. Therefore, the second cleaning cloth speed is maintained at 160-260 rpm, which is the optimal speed after combining the stain cleaning effect and service life.

[0123] In the normal cleaning process of the second cleaning cloth, as described above, the second cleaning assembly has a water scraping rib and a protrusion, and the loss of the second cleaning cloth per unit time is higher than that of the conventional ground. In order to maintain the relationship between cleaning efficiency and service life of the second cleaning cloth, the speed must be maintained in a stable and reasonable range, such as 160-260 rpm as described above. Too low speed cleaning efficiency is too low, and too high speed will damage the second cleaning cloth, and will not increase the cleaning efficiency, but will produce more noise and affect normal work. Therefore, during the cleaning process, the second cleaning cloth rotates at a speed within the above range, which can improve the cleaning effect without affecting the service life of the second cleaning cloth.

[0124] The pressure borne by the second cleaning assembly 220 is 3-10 N. Since the second cleaning assembly is a floating structure, controlling the bearing pressure of 3-10 N can make the second cleaning cloth and the cleaning plate 212 of the second cleaning assembly 220 just in a stable contact force range. A pressure of 3-10 N can avoid overloading the cleaning plate 212 to increase the friction force, thereby affecting the service life of the second cleaning cloth, and can also avoid too small bearing pressure to make the friction force insufficient, thereby reducing the cleaning effect. Therefore, the pressure borne by the second cleaning assembly 220 is 3-10 N, so that the friction force of the cleaning plate 212 is in a balanced range for the cleaning effect and wear degree of the second cleaning cloth.

[0125] The distribution density of the protrusions is 1 / cm 2 -6 / cm 2 . The cleaning plate 212 bears a pressure of 3-10 N, and under this bearing pressure, the distribution density of the protrusions is set to 1 / cm 2 -6 / cm 2 , which can achieve the best cleaning effect of the second cleaning cloth.

[0126] The height of the protrusions is 1mm-3mm, and the pressure borne by the cleaning plate 212 is 3-10N, so that under the bearing pressure, the height of the protrusions is 1mm-3mm, so that the second cleaning cloth can achieve the best cleaning effect. With the increase of the height of the protrusions, the cleaning efficiency also increases, and the height of 1mm-3mm has higher stable cleaning efficiency, basically maintaining the cleaning efficiency of more than 70%, and when the height is too high, the cleaning efficiency is also high, but the increment is not obvious, and the height of the protrusions is too high, which will cause the wear of the second cleaning cloth. Therefore, in order to balance the relationship between the two, the height of the protrusions is 1mm-3mm, which is more ideal. BRIEF DESCRIPTION OF DRAWINGS

[0142] FIGS. 1-2 are structural schematic diagrams of a base station for a cleaning robot according to an exemplary embodiment. The structure of the cleaning robot is not specifically limited, for example, the cleaning robot can be a floor washing robot, a floor mopping robot, a sweeping and mopping integrated robot, etc.

[0143] The embodiment provides a base station for a cleaning robot, which is mainly used for cleaning a first cleaning cloth and a second cleaning cloth on a cleaning device, and specifically, the base station comprises a clean water tank and a sewage tank and a body 100 and a base 200, the body 100 can be designed as a non-detachable structure with the base 200 or a detachable structure, the base 200 can support the body 100, the base 200 has an inclined surface 210, the cleaning device can be automatically moved to the base 200 through the inclined surface 210 or manually transferred; a lower part of the base station body 100 and the base 200 jointly form a containing cavity 300 opening forward, and the containing cavity 300 is used for containing the automatic cleaning device when the automatic cleaning device returns to the base station for maintenance operation. A cleaning tank 310 is arranged at a position of the base 200 in the containing cavity 300, and the cleaning tank 310 is used for cleaning the cleaning cloths on the automatic cleaning device through a cleaning assembly in the cleaning tank 310 when the automatic cleaning device enters the containing cavity 300. When the automatic cleaning device, for example, a cleaning robot, moves along the inclined surface 210 of the base 200 to the containing cavity 300 after completing a cleaning task, the cleaning cloths of the automatic cleaning device are arranged in the cleaning tank 310 for cleaning. The base 200 is provided with at least one liquid inlet and at least one liquid outlet, and the liquid inlet and the liquid outlet are in communication with the cleaning tank 310; the liquid inlet is in communication with the clean water tank on the base station to provide cleaning liquid for the cleaning tank 310, and the liquid outlet is in communication with the sewage tank on the base station, and the sewage in the cleaning tank 310 after cleaning can be directly discharged to the sewage tank through the liquid outlet.

[0144] As shown in FIG. 1, in order to more clearly describe the positional relationship of each component of the base station, the following direction definitions are made: front-back axis x, left-right axis y and up-down axis z. The arrow direction along the front-back axis x is marked as “forward direction”, and the arrow direction opposite to the front-back axis x is marked as “backward direction”. The left-right axis y is perpendicular to the front-back axis x in the horizontal plane, the arrow direction along the left-right axis y is “left direction”, and the arrow direction opposite to the left-right axis y is “right direction”; the up-down axis z is perpendicular to the front-back axis x and the left-right axis y, and is substantially perpendicular to the upper surface of the base or the body, and is usually perpendicular to the ground, the head direction along the up-down axis z is “upward direction”, and the arrow direction opposite to the up-down axis z is “downward direction”.

[0145] However, with the development of the cleaning device, many cleaning devices have small cloths in addition to large cloths, and the cleaning device cleans the heavy stain area or the corner area that cannot be covered by the large cloth through the small cloth. The existing base station cannot clean the small cloth of the cleaning device, and cannot consider the cleaning process of the large and small cloths, which causes trouble to the cleaning of the small cloth.

[0146] As shown in FIG. 1 and FIG. 2, the base station for cleaning robot provided by the embodiment of the present disclosure comprises a body 100 and a base 200, the base 200 carries the body 100, a containing cavity 300 is formed between the body 100 and the base 200, and the containing cavity 300 is configured to be capable of containing the cleaning robot; the base station further comprises a cleaning tank 310, the cleaning tank 310 is arranged on the base 200 and located within the projection range of the containing cavity 300 on the base 200, the cleaning tank 310 has a first cleaning assembly 320 therein, the first cleaning assembly 320 is configured to be capable of cleaning the first cleaning cloth of the cleaning robot in a first motion mode; a second cleaning assembly 220, the second cleaning assembly 220 is arranged on the base 200 and located outside the projection range of the containing cavity 300 on the base 200, the second cleaning assembly 220 is configured to be capable of cleaning the second cleaning cloth of the cleaning robot in a second motion mode; wherein, when performing a cleaning task, the first motion mode is a reciprocating linear motion, and the motion frequency of the reciprocating linear motion is M; the second motion mode is a continuous rotary motion, and the rotary speed of the second cleaning cloth is N revolutions per minute, and the N is a non-integer multiple of the M.

[0147] As shown in FIG. 1-FIG. 2, the first cleaning assembly 320 is arranged in the cleaning tank 310 along the front-rear direction, the first cleaning assembly 320 generally comprises a scraping blade, a liquid inlet and other components, the scraping blade is also arranged along the front-rear direction, and the scraping blade is used to reciprocate on the surface of the first cleaning cloth to scrape off the stains on the surface of the first cleaning cloth. During the cleaning process of the first cleaning assembly 320 on the surface of the first cleaning cloth, the clean water in the clean water tank is flushed into the first cleaning cloth through the pipeline and the liquid inlet, and the dirty water is squeezed out and enters the cleaning tank after the first cleaning cloth is scraped by the scraping blade. The first cleaning assembly 320 reciprocates along the left-right direction of the cleaning tank 310 at a certain frequency (denoted as M, unit: times per minute), so as to repeatedly scrape the first cleaning cloth, thereby achieving the purpose of cleaning. Since the liquid inlet is continuously supplied with water, a part of the clean water is absorbed by the first cleaning cloth and then forms dirty water after being scraped, therefore, the dirty water in the first cleaning cloth continuously flows into the cleaning tank 310 during the continuous scraping process of the scraping blade, and the dirty water in the cleaning tank 310 will present uneven distribution on the left and right sides of the first cleaning assembly 320 along with the left and right movement of the first cleaning assembly 320, for example, when the first cleaning assembly 320 moves to the left, the water amount in the cleaning tank 310 on the left side of the first cleaning assembly 320 will be more than that in the cleaning tank 310 on the right side of the first cleaning assembly 320, and vice versa, when the first cleaning assembly 320 moves to the right, the water amount in the cleaning tank 310 on the right side of the first cleaning assembly 320 will be more than that in the cleaning tank 310 on the left side of the first cleaning assembly 320.

[0148] In some embodiments, as shown in FIGS. 1-2, the second cleaning assembly 220 is generally disposed on the base 200 and outside the projection range of the containing cavity 300 on the base 200. In this embodiment, the second cleaning assembly 220 is disposed on the right side of the base station 100. The second cleaning assembly 220 can be disposed on the left side or other positions of the base station 100 according to the position of the second cleaning cloth in the cleaning device. The second cleaning assembly 220 cleans the second cleaning cloth of the cleaning robot in a non-continuous rotation manner. The second cleaning assembly 220 is provided with a water scraping rib. The second cleaning assembly 220 scrapes the sewage of the second cleaning cloth through the water scraping rib. The sewage in the second cleaning cloth is discharged into the washing tank 310 and then discharged from the liquid outlet after being combined with the sewage of the first cleaning cloth. The second cleaning assembly 220 controls the rotation of the second cleaning cloth at a certain frequency (denoted as N, unit: times / min). That is, the second cleaning assembly 220 rotates at a certain rotation frequency. The rotation frequency is denoted as N. In each rotation process, the second cleaning assembly 220 can rotate continuously at least once. In each rotation process, the second cleaning assembly 220 discharges water into the washing tank 310 once. The second cleaning assembly 220 rotates at a rotation frequency N. Therefore, the second cleaning assembly 220 periodically discharges water into the washing tank 310, and the water discharge frequency is also N. Since the second cleaning assembly 220 periodically discharges water into the washing tank 310, and the second cleaning assembly 220 is disposed on the base 200 and outside the projection range of the containing cavity 300 on the base 200, in order not to affect the sewage in the second cleaning assembly 220 entering the washing tank 310, when the second cleaning assembly 220 discharges water into the washing tank 310, it should be avoided to meet the water amount peak in the washing tank 310 on the right side of the first cleaning assembly 320. Otherwise, the sewage in the second cleaning assembly 220 cannot be smoothly discharged into the washing tank 310, and it is also possible to cause the sewage in the sewage tank to flow back into the second cleaning assembly 220, and even overflow to the base 200.

[0149] Specifically, as shown in FIG. 3, FIG. 3 exemplarily shows the water amount change state diagram of the first cleaning assembly 320 and the second cleaning assembly 220, wherein the data is not the real data amount, but is used to express the periodic relationship between the two, wherein S1 represents the periodic change state diagram of the water amount in the right cleaning tank 310 of the first cleaning assembly 320 in the reciprocating motion process, and S2 represents the periodic change state diagram of the water discharge of the second cleaning assembly 220 into the cleaning tank 310 in the periodic non-continuous rotating motion process, wherein the first cleaning assembly 320 reciprocates linearly at a certain frequency, here the reciprocating linear motion refers to that the first cleaning assembly 320 scrapes water to the left and to the right once as a period, for example, the first cleaning assembly 320 starts to scrape water to the right from the leftmost end of the cleaning tank, reaches the rightmost end after 0.5 periods, and then scrapes water to the left from the rightmost end to the starting position (the leftmost end) as one period T, in order to express uniformly, the number of periods completed in unit time, i.e. the motion frequency of the first cleaning assembly 320 is expressed, and the motion frequency of the first cleaning assembly 320 is denoted as M, with the unit of times / min. The second cleaning assembly 220 cleans the second cleaning cloth at a certain frequency, and in the cleaning process, the second cleaning cloth rotates non-continuously while the second cleaning assembly 220 periodically scrapes water on the second cleaning cloth, the second cleaning cloth rotates once (at least rotates 1 turn once), and the second cleaning assembly 220 continuously scrapes water on the second cleaning cloth once, in order to express uniformly, the number of water scraping periods completed in unit time, i.e. the water discharge frequency of the second cleaning assembly 220 is expressed, and the water discharge frequency of the second cleaning assembly 220 is denoted as N, with the unit of times / min.

[0150] As shown in FIG. 3, when the water discharge frequency N of the second cleaning assembly 220 in unit time T is an integer multiple of the motion frequency M of the first cleaning assembly, for example, the water discharge frequency N of the second cleaning assembly 220 is an odd multiple of the motion frequency M of the first cleaning assembly, for example, N is 5 and M is 1, then the water discharge peak period of the second cleaning assembly 220 must meet the water amount peak period in the right cleaning tank of the first cleaning assembly, thereby causing the sewage in the sewage tank to flow back into the second cleaning assembly 220, and even overflow to the base 200. Therefore, in order to avoid the occurrence of this accident, when setting the rotating state of the second cleaning assembly, it is necessary to set the water discharge frequency N of the second cleaning assembly 220 as a non-integer multiple of the motion frequency M of the first cleaning assembly, so that in the cleaning process of the second cleaning cloth and the first cleaning cloth long enough, the water discharge peak of the second cleaning assembly 220 will not meet the water amount peak in the right cleaning tank of the first cleaning assembly repeatedly, thereby possibly avoiding the occurrence of this kind of water leakage event.

[0151] In some embodiments, the rotating speed of the second cleaning cloth is controlled to be 160-260 revolutions / min, which can ensure that the second cleaning cloth is uniformly stressed during water discharge.

[0152] The second cleaning assembly 220 bears a pressure of 3-10 Newton. Since the second cleaning assembly is a floating structure, the pressure of 3-10 Newton borne by the second cleaning assembly can enable the second cleaning cloth to be in a stable contact force range with the cleaning plate 212 of the second cleaning assembly 220, the pressure of 3-10 Newton can avoid the cleaning plate 212 from being overloaded to increase the friction, thereby affecting the service life of the second cleaning cloth, and can also avoid the pressure being too small to make the friction insufficient, thereby reducing the cleaning effect, therefore, the pressure of 3-10 Newton borne by the second cleaning assembly 220 can make the friction of the cleaning plate 212 be in a balanced range for the cleaning effect and the wear degree of the second cleaning cloth.

[0153] In some embodiments, as shown in FIG. 4, as shown in FIG. 5, the second cleaning assembly 220 includes a sewage tank 211 and a cleaning plate 212, the sewage tank 211 is in communication with the cleaning tank 310, so that the sewage in the sewage tank 211 enters the cleaning tank 310 and then is discharged through the drain in the cleaning tank 310; the cleaning plate 212 is arranged in the sewage tank 211, and the cleaning plate 212 is configured to be able to clean the second cleaning cloth with the rotation of the second cleaning cloth, and optionally, the projection area of the cleaning plate 212 on the horizontal plane is smaller than the projection area of the sewage tank 211 on the horizontal plane, so that there is a gap between the cleaning plate 212 and the sewage tank 211, which is used to guide the sewage on the cleaning plate 212 into the sewage tank 211.

[0154] In some embodiments, as shown in FIG. 6, the sewage tank 211 has a non-closed side wall 2111, the non-closed side wall 2111 has a gap 2112 on the side facing the cleaning tank 310, the gap 2112 is used to discharge the sewage in the sewage tank 211 into the cleaning tank 310, and the non-closed side wall 2111 forms a generally circular ring structure to adapt to the shape of the second cleaning cloth. The sewage tank 211 has a first connecting piece 2113 therein, the first connecting piece 2113 can be a multi-prism structure, for example, a 3-6 prism, to avoid the rotation of the cleaning plate 212 itself, the outer surface of the first connecting piece 2113 has a plurality of clamping pieces 2114, the clamping pieces 2114 are clamped and connected with the cleaning plate 212; the first connecting piece 2113 has an elastic piece 2115 therein, the elastic piece 2115 is elastically connected with the lower surface of the cleaning plate 212, so that the cleaning plate 212 can float within a certain range in the cleaning tank 310. The sewage tank 211 has a water injection pipe 2116 therein, the water injection pipe 2116 is in communication with the base station clean water tank, and injects clean water into the second cleaning assembly 220 under the control of the controller, and optionally, the end of the water injection pipe 2116 has a sealing joint 2117, the sealing joint 2117 enables the water injection pipe 2116 to be sealingly connected with the water injection port 2128 of the cleaning plate 212.

[0155] In some embodiments, as shown in FIG. 7, the cleaning plate 212 has a second connecting member 2121 on one side of the sewage tank 211, the second connecting member 2121 has a plurality of openings 2122 corresponding to the plurality of locking members 2114; wherein the first connecting member 2113 extends into the second connecting member 2121, the plurality of locking members 2114 extend into the plurality of openings 2122, and the plurality of openings 2122 have a redundant space in the up-down direction to allow the cleaning plate 212 to be connected floatingly in the sewage tank 211. The cleaning plate 212 can have a certain elasticity in the up-down direction in the sewage tank 211 by the elastic member 2115. When the second cleaning cloth of the cleaning device is locked on the cleaning plate 212, the cleaning plate 212 sinks by a certain distance to give a certain redundant space, so that the second cleaning cloth is in stable contact with the cleaning plate 212, and the first cleaning cloth is in stable contact with the first cleaning assembly 320, which is beneficial to the efficient cleaning of the second cleaning cloth and the first cleaning cloth.

[0156] In some embodiments, as shown in FIG. 7, the cleaning plate 212 includes a limiting member 2127 configured to limit the second cleaning cloth. The limiting member 2127 is located near the edge of the cleaning plate 212, substantially on the downstream side of the second cleaning cloth rotation direction of the gap 2112, and has a substantially inverted L-shaped structure. When the second cleaning cloth reaches the cleaning plate 212, it will be locked in the limiting member 2127, so that the cleaning device cannot advance into the containing cavity of the base station, so that it is just located on the second cleaning assembly 220. Optionally, the limiting member 2127 can be 1-3 to stably limit the second cleaning cloth.

[0157] In some embodiments, the cleaning plate 212 further includes a water injection port 2128 for injecting clean water to the second cleaning cloth, the water injection port 2128 is arranged on the downstream side of the second cleaning cloth rotation direction of the limiting member 2127; the water injection port 2128 is sealingly connected with the sealing joint 2117 at the end of the water injection pipe 2116, so that the clean water can wet the second cleaning cloth from bottom to top.

[0158] In some embodiments, as shown in FIG. 7, the cleaning plate 212 includes a plurality of protrusions 2125, which are arranged at a non-central position of the cleaning plate 212 and at a position approximately at one side of the cleaning plate 212, for example, at a position approximately at a downstream side of the water injection port 2128 in the rotation direction of the second cleaning cloth, and the plurality of protrusions 2125 are configured to be capable of cleaning the second cleaning cloth by friction. As clean water is injected from the water injection port 2128 to the second cleaning cloth, the second cleaning cloth is then cleaned by friction by the plurality of protrusions 2125, and the cleaning effect is better. The part of the sewage squeezed out by the plurality of protrusions 2125 flows into the sewage tank 211 along the gap between the cleaning plate 212 and the edge of the sewage tank 211. Optionally, the cleaning plate 212 includes a plurality of drainage holes 2126, which are arranged at intervals with the plurality of protrusions 2125, and the plurality of drainage holes 2126 are used to timely drain the sewage generated by the plurality of protrusions 2125. Optionally, the plurality of protrusions 2125 are not located near the center of the cleaning plate 212, because the center position does not form a unique during the rotation of the second cleaning cloth, and the protrusions 2125 located near the center of the cleaning plate 212 cannot clean the center of the second cleaning cloth. The plurality of protrusions 2125 increase in height from the center to the edge of the cleaning plate 212, and due to the centrifugal effect, the contact force between the edge of the second cleaning cloth and the cleaning plate 212 will decrease, and at this time, increasing the height of the protrusions 2125 at the edge can make up for the decrease in friction caused by the centrifugal effect, and enhance the cleaning effect.

[0159] In some embodiments, the distribution density of the protrusions is 1 / cm 2 -6 / cm 2 , and the height of the protrusions is 1mm-3mm. The cleaning plate 212 bears a pressure of 3-10N, and under this bearing pressure, the distribution density of the protrusions arranged is 1 / cm 2 -6 / cm 2 , and the height of the protrusions is 1mm-3mm, which can make the second cleaning cloth achieve the best cleaning effect.

[0160] In some embodiments, as shown in FIG. 7, the cleaning plate further comprises a wiping rib 2123 arranged along the edge of the cleaning plate 212 in the radial direction of the cleaning plate, the wiping rib 2123 is configured to be able to wipe off the dirty water on the second cleaning cloth, the wiping rib 2123 has a higher protruding structure than the plurality of protrusions 2125, so as to wipe off the dirty water on the second cleaning cloth as much as possible during the finishing process. The wiping rib 2123 is located near the gap 2112, and in some embodiments, the cleaning plate 212 further comprises a drainage gap 2124 arranged on the side of the wiping rib 2123 upstream in the rotation direction of the second cleaning cloth, the drainage gap 2124 is configured to be able to guide the dirty water wiped off by the wiping rib 2123. As the wet second cleaning cloth rotates from the water inlet 2128 to the wiping rib 2123, it is rubbed by the plurality of protrusions 2125 and then strongly wiped by the wiping rib 2123, which can ensure that a complete decontamination operation is realized in one rotation cycle of the second cleaning cloth, and the dirty water will flow from the drainage gap 2124 to the cleaning tank and then be discharged.

[0161] From the structure of the cleaning plate 212, it can be seen that the decontamination structure on the upper surface of the cleaning plate 212 is arranged in the clockwise direction from the limiting member 2127, and then arranged in the order of the water inlet 2128, the plurality of protrusions 2125 and the plurality of drainage holes 2126 arranged alternately, the drainage gap 2124, and finally the wiping rib 2123 for finishing, completing the cycle of wetting, wiping, wiping and decontamination of the second cleaning cloth in one rotation cycle, which can effectively realize the decontamination of the second cleaning cloth in one rotation cycle. With continuous rotation of the second cleaning cloth, the second cleaning cloth can be completely cleaned.

[0162] As shown in FIG. 8, the experimental results show the relationship between the stain cleaning rate and the rotation speed of the second cleaning cloth. In some embodiments, the rotation speed of the second cleaning cloth is controlled to be 160-260 rpm, and the stain cleaning rate is optimal. The rotation speed can be a continuous rotation speed during the cleaning process or a single rotation speed during non-continuous rotation. In this experiment, the second cleaning cloth is placed in the mud and soaked completely, and then placed in the base station for cleaning. The relationship between the stain cleaning rate and the rotation speed of the second cleaning cloth is analyzed. The cleaning time is controlled to be 5 minutes each time, and the stain cleaning rate is calculated by continuously adjusting the rotation speed of the second cleaning cloth. The stain cleaning rate refers to the ratio of the amount of cleaned stains to the total amount of stains before cleaning. Specifically, the weight of the second cleaning cloth in a clean state G and the weight of the second cleaning cloth after absorbing the mud G1 are measured before the experiment. The difference between the two is the weight of the absorbed mud AG1=G1-G. After 5 minutes of cleaning, the weight of the second cleaning cloth G2 is measured, and the weight of the cleaned stains is AG2=G1-G2. The stain cleaning rate P=(AG2 / AG1)*100%.

[0163] As described above, the stain cleaning rate and the rotation speed of the second cleaning cloth are measured multiple times, as shown in FIG. 8. When the rotation speed of the second cleaning cloth reaches 160 rpm, the stain cleaning rate is significantly improved from about 50% to about 70%, which can meet the cleaning requirements of the second cleaning cloth. With further increase of the rotation speed, when the rotation speed of the second cleaning cloth reaches 260 rpm, the stain cleaning rate of the second cleaning cloth is basically close to 95%, which almost completely cleans the stains of the second cleaning cloth. Further increasing the rotation speed of the second cleaning cloth to more than 260 rpm will basically maintain the corresponding stain cleaning rate. In addition, the power consumption and noise will also increase significantly. Therefore, the rotation speed of the brush is maintained at 160-260 rpm, which can effectively clean the stains of the second cleaning cloth.

[0164] As shown in FIG. 8, the relationship between the second cleaning cloth life and the second cleaning cloth rotation speed is further analyzed in combination with the experimental given stain cleaning rate / second cleaning cloth life and second cleaning cloth rotation speed graph. In this experiment, a new clean second cleaning cloth is placed in the base station, and it is continuously rotated to the same degree of wear. For example, the degree of wear is calculated by the method described above to determine whether it has reached the same degree of wear, thereby determining the service life of the second cleaning cloth. The service life of the second cleaning cloth refers to the time from the brand-new state to the severely worn state of the second cleaning cloth, which is measured in units of accumulated hours. The severely worn state refers to a wear standard, which can be optionally set to 60% wear of the second cleaning cloth as the severely worn state. The wear standard can be set to other values and is not strictly limited. As can be seen from the graph, the second cleaning cloth has a basically stable service life at a low rotation speed. When the second cleaning cloth rotation speed reaches 160 rpm, the service life of the second cleaning cloth begins to decline steadily. When the roller brush rotation speed exceeds 260 rpm, the service life of the second cleaning cloth decreases significantly. Therefore, the second cleaning cloth rotation speed is maintained at 160-260 rpm, which is the optimal rotation speed after considering the stain cleaning effect and service life.

[0165] In some embodiments, in the working state of cleaning the second cleaning cloth, the rotation speed of the second cleaning cloth is greater than 190 rpm and less than 240 rpm. Specifically, the rotation speed of the second cleaning cloth can be 200 rpm, 210 rpm, 220 rpm, 230 rpm, etc. At this time, as shown in FIG. 8, the cleaning rate of the second cleaning cloth has a higher stable interval, and its service life also has a higher stable interval.

[0166] In the normal process of cleaning the second cleaning cloth, the second cleaning assembly has a water scraping rib 2123 and a protrusion 2125, as described above in the structure description of the second cleaning assembly. The wear of the second cleaning cloth per unit time is higher than that of the conventional ground. In order to maintain the relationship between the cleaning efficiency and the service life of the second cleaning cloth, the rotation speed must be maintained in a stable and reasonable interval, such as 160-260 rpm as described above. Too low rotation speed will result in too low cleaning efficiency, and too high rotation speed will cause high damage to the second cleaning cloth and will not improve the cleaning efficiency. Instead, it will produce more noise and affect normal work. Therefore, during the cleaning process, the second cleaning cloth is rotated at a rotation speed within the above range, which can improve the cleaning effect without affecting the service life of the second cleaning cloth.

[0167] In some embodiments, in the working state of cleaning the second cleaning cloth, the rotation speed of the second cleaning cloth can also be less than 160 rpm. For example, 90 rpm, in particular, the rotation speed of the second cleaning cloth can be any value between 70 rpm and 260 rpm, such as 70 rpm-100 rpm, 70 rpm-140 rpm, 70 rpm-160 rpm, 70 rpm-200 rpm, 70 rpm-220 rpm, etc. At this time, as shown in FIG. 8, the service life of the second cleaning cloth has a higher stable interval, which is basically stable at more than 80 hours, which is an optimal service life rotation speed. At low speed, although the cleaning efficiency is low, the cleaning efficiency can be compensated by increasing the cleaning time, therefore, the rotation speed of the second cleaning cloth of the present disclosure can be any value between 70 rpm and 260 rpm.

[0168] In some embodiments, as shown in FIG. 9, the distribution density of the protrusions is 1 / cm 2 -6 / cm 2 . The cleaning plate 212 bears a pressure of 3-10 N, and under this bearing pressure, the distribution density of the protrusions is set to 1 / cm 2 -6 / cm 2 , which can make the second cleaning cloth achieve the best cleaning effect. In the experiment process, the cleaning rate of the second cleaning cloth is defined as described above, which is not repeated here. In the experiment process, the bearing pressure of 6 N is selected, and the distribution density of the protrusions is tested from 1 / cm 2 -16 / cm 2 . As can be seen from FIG. 9, at low density, the density of 1 / cm 2 -6 / cm 2 has a higher cleaning efficiency, which is basically maintained at more than 70% cleaning efficiency, and when the density exceeds 6 / cm 2 , the granularity effect of the protrusion particles is not obvious, and the stain removal effect is reduced.

[0169] In some embodiments, as shown in FIG. 10, the height of the protrusions is 1mm-3mm, and the pressure borne by the cleaning plate 212 is 3-10N, and under this bearing pressure, the height of the protrusions is set to 1mm-3mm, which can enable the second cleaning cloth to achieve the best cleaning effect. In the experimental process, the cleaning rate of the second cleaning cloth is defined as described above, and will not be repeated here. In the experimental process, the bearing pressure of 6N is selected, and the height of the protrusions is tested from 0.5mm to 5mm. As can be seen from FIG. 10, as the height of the protrusions increases, the cleaning efficiency also increases, and the height of 1mm-3mm has a relatively high and stable cleaning efficiency, which is basically maintained at a cleaning efficiency of more than 70%. When the height is too high, the cleaning efficiency is also high, but the increase is not obvious, and the height of the protrusions is too high, which will cause damage to the second cleaning cloth. Therefore, in order to balance the relationship between the two, the height of the protrusions is selected to be 1mm-3mm, which is relatively ideal.

[0170] Finally, it should be noted that: each embodiment in the specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between each embodiment can be referred to each other. For the system or device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method part.
