[0061] According to a specific implementation of the present disclosure, the present disclosure also provides a cleaning system, comprising a base station and a cleaning robot as described in any one of the above embodiments.

[0062] Compared with the prior art, the embodiments of the present disclosure have the following technical effects: the cleaning robot base station of the present disclosure is provided with a second cleaning component, so that it is provided on the base and is located outside the projection range of the accommodating cavity on the base, and the second cleaning rag of the cleaning robot can be cleaned in a second motion mode through the second cleaning component; and when performing a cleaning task, the first cleaning component cleans the first cleaning rag in a first motion mode by reciprocating linear motion, and the motion frequency of the reciprocating linear motion is M; the second cleaning component cleans the second cleaning rag by rotation in a second motion mode, and the rotation frequency of the second cleaning rag is N, and N is a non-integer multiple of M; the rotation speed of the second cleaning rag is 160-260 rpm. It can effectively take into account the cleaning process of the first cleaning component and the second cleaning component, and ensure the efficient cleaning of the first cleaning rag and the second cleaning rag.

[0063] Since the amount of water in the cleaning tank on the right side of the first cleaning component changes periodically, the drainage of the second cleaning component into the cleaning tank also changes periodically when the second cleaning component rotates discontinuously. Within the unit time T, if the drainage frequency N of the second cleaning component is an integer multiple of the motion frequency M of the first cleaning component, for example, the drainage frequency N of the second cleaning component is an odd multiple of the motion frequency M of the first cleaning component, for example, N is 5 and M is 1, then the drainage peak of the second cleaning component will inevitably meet the peak of the amount of water in the cleaning tank on the right side of the first cleaning component, thereby causing the sewage in the sewage tank to flow back into the second cleaning component and even overflow to the base. Therefore, in order to avoid the occurrence of this problem, when controlling the rotation of the second cleaning rag, it is necessary to set the drainage frequency N of the second cleaning component to a non-integer multiple of the motion frequency M of the first cleaning component. In this way, in the sufficiently long cleaning process of the second cleaning rag and the first cleaning rag, the drainage peak of the second cleaning component will definitely not repeatedly meet the peak of the amount of water in the cleaning tank on the right side of the first cleaning component, thereby possibly avoiding the occurrence of such water leakage incidents.

[0064] In addition, when the second cleaning rag rotates for cleaning, combined with the relationship diagram of the stain cleaning rate / life of the second cleaning rag and the rotation speed of the second cleaning rag, the rotation speed of the second cleaning rag is 160-260 rpm, and the stain cleaning rate is the best. When the rotation speed of the second cleaning rag reaches 160 rpm, the stain cleaning rate will be significantly improved, from about 50% or less to about 70% or more, which can meet the cleaning of the second cleaning rag. With the further increase in the rotation speed, when the rotation speed of the second cleaning rag reaches 260 rpm, the cleaning rate of the second cleaning rag is basically close to 95%, and the stains on the second cleaning rag have almost been cleaned. When the rotation speed of the second cleaning rag is increased to more than 260 rpm, it will basically maintain near the corresponding stain cleaning rate. In addition, excessive speed will cause a significant increase in power consumption and noise. Therefore, the roller brush speed is maintained at 160-260 rpm, which can effectively clean the stains on the second cleaning rag.

[0065] Combined with the stain cleaning rate / second cleaning rag life and second cleaning rag speed relationship diagram given by the experiment, the relationship between the second cleaning rag life and the second cleaning rag speed is further analyzed. The second cleaning rag has a basically stable service life at low speed. When the second cleaning rag speed reaches 160 rpm, the service life of the second cleaning rag begins to decline steadily. When the roller brush speed exceeds 260 rpm, the service life of the second cleaning rag decreases significantly. Therefore, the second cleaning rag speed is maintained at 160-260 rpm, which is the optimal speed after combining the stain cleaning effect and service life.

[0066] During the normal cleaning process of the base station, as can be seen from the structural description of the second cleaning component in the above embodiment, the second cleaning component has scraping ribs and protrusions. The loss of the second cleaning rag per unit time is higher than that of the conventional floor. In order to maintain the relationship between the cleaning efficiency and the service life of the second cleaning rag, its rotation speed must be maintained in a stable and reasonable range, such as 160-260 rpm as mentioned above. Too low a rotation speed will cause too low cleaning efficiency, and too high a rotation speed will cause high damage to the second cleaning rag, and will not increase the cleaning efficiency. Instead, it will generate greater noise and affect normal work. Therefore, during the cleaning process, the second cleaning rag is rotated at a rotation speed within the above range, which can improve the cleaning effect without affecting the life of the second cleaning rag.

[0067] The pressure carried by the second cleaning component 220 is 3-10 Newtons. Since the second cleaning component is a floating structure, controlling the pressure carried by it to 3-10 Newtons can make the second cleaning rag and the cleaning plate 212 of the second cleaning component 220 just in a stable contact force range. The pressure of 3-10 Newtons can avoid overloading the cleaning plate 212 and increasing the friction, thereby affecting the life of the second cleaning rag, and can also avoid too small bearing pressure resulting in insufficient friction and reduced cleaning effect. Therefore, the pressure carried by the second cleaning component 220 is 3-10 Newtons, so that the friction of the cleaning plate 212 is in a balanced range for the cleaning effect and wear degree of the second cleaning rag.

[0068] The distribution density of the protrusions is 1 / cm 2 -6 pieces / cm 2 The pressure on the cleaning plate 212 is 3-10 Newtons. Under this pressure, the distribution density of the protrusions is set to 1 / cm 2 -6 pieces / cm 2 , which can enable the second cleaning cloth to achieve the best cleaning effect.

[0069] The height of the protrusion is 1mm-3mm, and the pressure of the cleaning plate 212 is 3-10 Newtons. Under this bearing pressure, setting the height of the protrusion to 1mm-3mm can enable the second cleaning rag to achieve the best cleaning effect. As the height of the protrusion increases, the cleaning efficiency also increases. A height of 1mm-3mm has a relatively high and stable cleaning efficiency, which basically maintains a cleaning efficiency of more than 70%. When the height is too high, the cleaning efficiency is also very high, but the added value is not obvious, and a high protrusion height will cause loss to the second cleaning rag. Therefore, in order to balance the relationship between the two, it is more ideal to select a protrusion height of 1mm-3mm. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0083] The technical solution of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0084] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0085] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or device. In the absence of more restrictions, the elements defined by the sentence "comprises a" do not exclude the presence of other identical elements in the product or device including the elements.

[0086] Figure 1-Figure 2 It is a structural diagram 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 mopping robot, a sweeping and mopping robot, etc.

[0087] The present embodiment provides a base station for a cleaning robot, which is mainly used to clean the first cleaning rag and the second cleaning rag on the cleaning device. Specifically, the base station includes a body 100 and a base 200. The body 100 and the base 200 can be designed as a non-detachable structure 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 can be transferred manually. The lower part of the base body 100 and the base 200 together form a forward-opening accommodating chamber 300, which is used to accommodate the automatic cleaning device when it returns to the base station for maintenance operations. A cleaning tank 310 is provided on the base 200 at a position inside the accommodating chamber 300. The cleaning tank 310 is used to clean the cleaning rag on the automatic cleaning device through the cleaning component in the cleaning tank 310 after the automatic cleaning device enters the accommodating chamber 300. When an automatic cleaning device, such as a cleaning robot, completes a cleaning task, the automatic cleaning device will move along the inclined surface 210 of the base 200 to the accommodating chamber 300, so that the cleaning wipe of the automatic cleaning device is arranged in the cleaning tank 310 for cleaning; at least one liquid inlet and at least one liquid discharge port are provided on the base 200, and both the liquid inlet and the liquid discharge port are connected to the cleaning tank 310; the liquid inlet is connected to the clean water tank on the base station to provide cleaning liquid for the cleaning tank 310, and the liquid discharge port is connected to the sewage tank on the base station, and the sewage after cleaning in the cleaning tank 310 can be directly discharged into the sewage tank through the liquid discharge port.

[0088] like Figure 1 As shown, in order to more clearly describe the positional relationship of the various components of the base station, the following directions are defined: front-to-back axis x, left-to-right axis y, and up-to-down axis z. The arrow direction along the front-to-back axis x is marked as "forward", and the opposite direction of the arrow along the front-to-back axis x is marked as "backward". The left-to-right axis y is an axis perpendicular to the front-to-back axis x in the horizontal plane. The direction along the arrow of the left-to-right axis y is "left", and the direction opposite to the arrow of the left-to-right axis y is "right"; the up-to-down axis z is an axis perpendicular to the front-to-back axis x and the left-to-right axis y. It is roughly perpendicular to the base or upper surface of the main body of the reference, and is usually also perpendicular to the ground. The direction along the up-to-down axis z is "upward", and the direction opposite to the arrow of the up-to-down axis z is "downward".

[0089] However, with the development of cleaning equipment, many cleaning equipment have small rags in addition to large rags. The cleaning equipment uses small rags to clean heavily stained areas or corners that are not covered by large rags. The existing base station cannot clean the small rag of the cleaning equipment, nor can it take into account the cleaning process of large and small rags, which brings troubles to the cleaning of the small rag.

[0090] like Figure 1 , Figure 2As shown, the embodiment of the present disclosure provides a base station for a cleaning robot, the base station includes a body 100 and a base 200, the base 200 carries the body 100, a receiving cavity 300 is formed between the body 100 and the base 200, and the receiving cavity 300 is configured to be able to accommodate the cleaning robot; the base station also includes a cleaning tank 310, the cleaning tank 310 is arranged on the base 200 and is located within the projection range of the receiving cavity 300 on the base 200, and the cleaning tank 310 has a first cleaning component 320, and the first cleaning component 320 is configured to be able to move with a first A first motion mode is used to clean the first cleaning cloth of the cleaning robot; a second cleaning component 220, the second cleaning component 220 is arranged on the base 200 and is located outside the projection range of the accommodating cavity 300 on the base 200, and the second cleaning component 220 is configured to clean 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 rotational motion, and the rotation speed of the second cleaning cloth is N rpm, and N is a non-integer multiple of M.

[0091] Among them, Figure 1-Figure 2 As shown, the first cleaning component 320 is generally extended in the front-to-back direction and arranged in the cleaning tank 310. The first cleaning component 320 generally includes components such as a scraper and a liquid inlet. The scraper is also arranged in the front-to-back direction. The scraper 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 process of the first cleaning component 320 cleaning 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. After the scraper scrapes the first cleaning cloth, the sewage is squeezed out and enters the cleaning tank. The first cleaning component 320 reciprocates along the left and right directions of the cleaning tank 310 at a certain frequency (denoted as M, in units of times / minute), thereby repeatedly scraping the first cleaning cloth to achieve the purpose of cleaning. Since the liquid inlet is for continuous water intake, a part of the clean water is absorbed by the first cleaning cloth and then scraped off to form sewage. Therefore, the sewage in the first cleaning cloth continuously flows into the cleaning tank 310 during the continuous scraping process of the scraper, and the sewage in the cleaning tank 310 will show an uneven distribution of water volume on the left and right sides of the first cleaning component 320 as the first cleaning component 320 moves left and right. For example, when the first cleaning component 320 moves to the left, the amount of water in the cleaning tank 310 on the left side of the first cleaning component 320 will be more than the amount of water in the cleaning tank 310 on the right side of the first cleaning component 320. Conversely, when the first cleaning component 320 moves to the right, the amount of water in the cleaning tank 310 on the right side of the first cleaning component 320 will be more than the amount of water in the cleaning tank 310 on the left side of the first cleaning component 320.

[0092] In some embodiments, Figure 1-Figure 2 As shown, the second cleaning component 220 is usually arranged on the base 200 and is located outside the projection range of the accommodating cavity 300 on the base 200. In this embodiment, the second cleaning component 220 is arranged on the right side of the base station 100. According to the position of the second cleaning cloth in the cleaning device, the second cleaning component 220 can be arranged on the left side of the base station 100 or other positions. The second cleaning component 220 cleans the second cleaning cloth of the cleaning robot in a non-continuous rotation manner. The second cleaning component 220 is provided with a scraper rib. The second cleaning component 220 scrapes off the sewage of the second cleaning cloth through the scraper rib. The sewage in the second cleaning cloth is discharged into the cleaning tank 310 and merged with the sewage of the first cleaning cloth and then discharged from the drain port. The second cleaning component 220 controls the rotation and cleaning of the second cleaning cloth at a certain frequency (denoted as N, unit times / minute), that is, it rotates at a certain rotation frequency, and the rotation frequency is denoted as N. During each rotation, the second cleaning component 220 can continuously The second cleaning component 220 continues to rotate for at least one circle. During each rotation process, the second cleaning component 220 drains water into the cleaning tank 310 once. The second cleaning component 220 is controlled to rotate at a rotation frequency N, so the second cleaning component 220 drains water into the cleaning tank 310 periodically, and the drainage frequency is also N. Since the second cleaning component 220 drains water into the cleaning tank 310 periodically, and the second cleaning component 220 is arranged on the base 200 and is located outside the projection range of the accommodating cavity 300 of the base 200, in order not to affect the sewage in the second cleaning component 220 from entering the cleaning tank 310, when the second cleaning component 220 drains water into the cleaning tank 310, it should be avoided as much as possible to meet the water peak in the cleaning tank 310 on the right side of the first cleaning component 320. Otherwise, the sewage in the second cleaning component 220 cannot be smoothly discharged into the cleaning tank 310, and the sewage in the sewage tank may be backflowed into the second cleaning component 220, or even overflow to the base 200.

[0093] Specifically, Figure 3 As shown, Figure 3The water volume change state diagram of the first cleaning component 320 and the second cleaning component 220 is shown as an example, wherein the data is not the actual data volume, but is only used to express the periodic relationship between the two, wherein S1 represents the periodic change state diagram of the water volume in the cleaning tank 310 on the right side of the first cleaning component 320 during the reciprocating motion, and S2 represents the periodic change state diagram of the second cleaning component 220 draining water into the cleaning tank 310 during the periodic non-continuous rotational motion, wherein the first cleaning component 320 reciprocates linearly at a certain frequency, and the reciprocating linear motion here means that the first cleaning component 320 wipes the water to the left and right once, which is recorded as one cycle. For example, the first cleaning component 320 starts to wipe the water to the right from the leftmost end of the cleaning tank, and it is 0.5 cycles after reaching the rightmost end, and then wipes the water from the rightmost end to the left to reach the starting position (the leftmost end) as a cycle T. For unified expression, it is expressed in terms of the number of cycles completed per unit time, that is, the movement frequency of the first cleaning component 320, and the movement frequency of the first cleaning component 320 is recorded as M, and the unit is times / minute. The second cleaning component 220 cleans the second cleaning cloth at a certain frequency. During the cleaning process, the second cleaning cloth rotates discontinuously and the second cleaning component 220 wipes the second cleaning cloth periodically. The second cleaning cloth rotates once (at least one rotation at a time), and the second cleaning component 220 wipes the second cleaning cloth continuously once. For unified expression, the drainage frequency of the second cleaning component 220 is expressed as the number of wiping cycles completed per unit time. The drainage frequency of the second cleaning component 220 is recorded as N, with the unit of times / minute.

[0094] like Figure 3 As shown, when the drainage frequency N of the second cleaning component 220 is an integer multiple of the motion frequency M of the first cleaning component within the unit time T, for example, the drainage frequency N of the second cleaning component 220 is an odd multiple of the motion frequency M of the first cleaning component, for example, N is 5 and M is 1, then the drainage peak of the second cleaning component 220 will inevitably meet the peak of the water volume in the cleaning tank on the right side of the first cleaning component, thereby causing the sewage in the sewage tank to flow back into the second cleaning component 220, and even overflow to the base 200. Therefore, in order to avoid the occurrence of this problem, when setting and controlling the rotation state of the second cleaning component, it is necessary to set the drainage frequency N of the second cleaning component 220 to be a non-integer multiple of the motion frequency M of the first cleaning component, so that in the sufficiently long cleaning process of the second cleaning rag and the first cleaning rag, the drainage peak of the second cleaning component 220 will definitely not repeatedly meet the peak of the water volume in the cleaning tank on the right side of the first cleaning component, thereby possibly avoiding the occurrence of such water leakage events.

[0095] In some embodiments, the rotation speed of the second cleaning cloth is controlled to be 160-260 rpm, which can ensure that the second cleaning cloth is evenly stressed and drains water.

[0096] The pressure borne by the second cleaning component 220 is 3-10 Newtons. Since the second cleaning component is a floating structure, the pressure borne by it is 3-10 Newtons, so that the second cleaning rag and the cleaning plate 212 of the second cleaning component 220 are just in a stable contact force range. The pressure of 3-10 Newtons can avoid overloading the cleaning plate 212 and increasing the friction, thereby affecting the life of the second cleaning rag, and can also avoid too small bearing pressure resulting in insufficient friction and reduced cleaning effect. Therefore, the pressure borne by the second cleaning component 220 is 3-10 Newtons, so that the friction of the cleaning plate 212 is in a balanced range for the cleaning effect and wear degree of the second cleaning rag.

[0097] In some embodiments, Figure 4 ,like Figure 5 As shown, the second cleaning component 220 includes a sewage trough 211 and a cleaning plate 212. The sewage trough 211 is connected to the cleaning trough 310, so that the sewage in the sewage trough 211 enters the cleaning trough 310 and is then discharged through the drain port in the cleaning trough 310; the cleaning plate 212 is arranged in the sewage trough 211, and the cleaning plate 212 is configured to be able to clean the second cleaning cloth as the second cleaning cloth rotates. Optionally, the projection area of ​​the cleaning plate 212 on the horizontal plane is smaller than the projection area of ​​the sewage trough 211 on the horizontal plane, so that there is a gap between the cleaning plate 212 and the sewage trough 211, and the gap is used to guide the sewage on the cleaning plate 212 into the sewage trough 211.

[0098] In some embodiments, Figure 6 As shown, the sewage tank 211 has a non-closed side wall 2111, and the non-closed side wall 2111 has a notch 2112 on the side facing the cleaning tank 310. The notch 2112 is used to discharge the sewage in the sewage tank 211 into the cleaning tank 310. The non-closed side wall 2111 forms a roughly circular ring structure to adapt to the shape of the second cleaning rag. The sewage tank 211 has a first connecting member 2113, which can be a multi-prism structure, such as a 3-6 prism, to prevent the cleaning plate 212 from rotating itself. The outer surface of the first connecting member 2113 has a plurality of locking members 2114, and the locking members 2114 are locked and connected with the cleaning plate 212; the first connecting member 2113 has an elastic member 2115, and the elastic member 2115 is elastically connected to 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. There is a water injection pipe 2116 in the sewage tank 211, and the water injection pipe 2116 is connected to the clean water tank of the base station. Under the control of the controller, clean water is injected into the second cleaning component 220. Optionally, the end of the water injection pipe 2116 has a sealing joint 2117, and the sealing joint 2117 makes the water injection pipe 2116 and the water injection port 2128 of the cleaning plate 212 sealed.

[0099] In some embodiments, Figure 7 As shown, the cleaning plate 212 has a second connecting member 2121 on one side facing the sewage tank 211, and the second connecting member 2121 has a plurality of openings 2122 corresponding to the plurality of stoppers 2114; wherein, after the first connecting member 2113 extends into the second connecting member 2121, the plurality of stoppers 2114 extend into the plurality of openings 2122, and the plurality of openings 2122 have redundant spaces in the up-down direction so that the cleaning plate 212 can be connected in a floating manner in the sewage tank 211. The cleaning plate 212 can have a certain elasticity in the up-down direction in the sewage tank 211 through the elastic member 2115. When the second cleaning rag of the cleaning device is stopped on the cleaning plate 212, the cleaning plate 212 sinks a certain distance to provide a certain redundant space, so that the second cleaning rag is in stable contact with the cleaning plate 212, and the first cleaning rag is in stable contact with the first cleaning assembly 320, which is conducive to efficient cleaning of the second cleaning rag and the first cleaning rag.

[0100] In some embodiments, Figure 7 As shown, the cleaning plate 212 includes a stopper 2127, which is configured to stop the second cleaning rag. The stopper 2127 is located near the edge of the cleaning plate 212, approximately on the downstream side of the notch 2112 in the rotation direction of the second cleaning rag. The stopper 2127 has a generally inverted L-shaped structure. When the second cleaning rag reaches the cleaning plate 212, it will be stuck in the stopper 2127, so that the cleaning device cannot move forward into the accommodating cavity of the base station, so that it is just located on the second cleaning assembly 220. Optionally, there can be 1-3 stoppers 2127 to stably stop the second cleaning rag.

[0101] In some embodiments, the cleaning plate 212 also includes a water injection port 2128, which is used to inject clean water into the second cleaning cloth. The water injection port 2128 is arranged on the downstream side of the second cleaning cloth's rotation direction of the limiting member 2127; the water injection port 2128 is sealedly connected to the sealing joint 2117 at the end of the water injection pipe 2116, so that clean water can wet the second cleaning cloth from the bottom to the top from the water injection port 2128.

[0102] In some embodiments, Figure 7As shown, 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 approximately half of the cleaning plate 212, for example, approximately at the downstream side of the water injection port 2128 in the rotation direction of the second cleaning rag, and the plurality of protrusions 2125 are configured to clean the second cleaning rag by friction. As clean water is injected into the second cleaning rag from the water injection port 2128, the wetted second cleaning rag is then rubbed and cleaned by a row of protrusions 2125, and the cleaning effect is better. 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 from the plurality of protrusions 2125, and the plurality of drainage holes 2126 are used to timely discharge the sewage generated by the friction of the plurality of protrusions 2125. Optionally, the plurality of protrusions 2125 are not located near the center of the cleaning plate 212. Since the center position of the second cleaning rag is not unique during the rotation process, the protrusion 2125 located near the center of the cleaning plate 212 cannot clean the center of the second cleaning rag. The plurality of protrusions 2125 increase in height from the center to the edge of the cleaning plate 212. Due to the centrifugal effect, the contact force between the edge of the second cleaning rag and the cleaning plate 212 will decrease. At this time, increasing the protrusion height of the edge protrusion 2125 can compensate for the reduction in friction caused by the centrifugal effect and enhance the cleaning effect.

[0103] In some embodiments, the distribution density of the protrusions is 1 / cm 2 -6 pieces / cm 2 The height of the protrusion is 1 mm to 3 mm. The pressure on the cleaning plate 212 is 3 to 10 Newtons. Under this pressure, the distribution density of the protrusions is set to 1 / cm 2 -6 pieces / cm 2 The height of the protrusion is 1mm-3mm, which can enable the second cleaning cloth to achieve the best cleaning effect.

[0104] In some embodiments, Figure 7As shown, the cleaning plate further includes a water scraping rib 2123, which is arranged at the edge of the cleaning plate along the radial direction of the cleaning plate 212, and the water scraping rib 2123 is configured to scrape off the dirty water on the second cleaning rag, and the water scraping rib 2123 has a higher protrusion structure than the plurality of protrusions 2125, so as to scrape off the dirty water on the second cleaning rag as much as possible during the finishing process. The water scraping rib 2123 is roughly located near the notch 2112. In some embodiments, the cleaning plate 212 further includes a drainage notch 2124, which is arranged on one side of the water scraping rib 2123 upstream along the rotation direction of the second cleaning rag, and the drainage notch 2124 is configured to be able to guide out the dirty water scraped off by the water scraping rib 2123. As the wet second cleaning cloth rotates from the water inlet 2128 to the scraper rib 2123, it is rubbed and removed by multiple protrusions 2125, and then scraped off with strong force by the scraper rib 2123, thereby ensuring that a complete decontamination operation is achieved within one rotation cycle of the second cleaning cloth. The sewage will flow from the drainage gap 2124 to the cleaning tank and then be discharged.

[0105] From the above structure of the cleaning plate 212, it can be seen that the decontamination structure on the upper surface of the cleaning plate 212 starts from the limit piece 2127, and is successively provided with a water inlet 2128, a plurality of protrusions 2125 and a plurality of drainage holes 2126, a drainage gap 2124 arranged alternately in a clockwise direction, and finally ends with a wiper rib 2123, thereby completing a cycle of wetting, scraping, wiping water and draining of dirt after one rotation of the second cleaning rag, and can effectively realize a decontamination operation of the second cleaning rag within one rotation cycle of the second cleaning rag, and with the continuous multiple rotations of the second cleaning rag, the second cleaning rag can be completely cleaned.

[0106] like Figure 8As shown, a relationship diagram of the stain cleaning rate / life of the second cleaning rag and the rotation speed of the second cleaning rag is given through experiments. In some embodiments, the rotation speed of the second cleaning rag is controlled to be 160-260 rpm, and the stain cleaning rate is optimal. The rotation speed here can be a continuous rotation speed during the cleaning process or a single rotation speed during non-continuous rotation. In this experiment, the relationship between the stain cleaning rate and the rotation speed of the second cleaning rag is tested. The second cleaning rag is artificially placed in the mud so that it is completely soaked in the mud, and then placed in the base station for cleaning. The stain cleaning rate and the rotation of the second cleaning rag are analyzed. The cleaning time of each cleaning process in this experiment is controlled at 5 minutes, and the stain cleaning rate is calculated by continuously adjusting the rotation speed of the second cleaning rag. Among them, the stain cleaning rate refers to the ratio of the amount of stains cleaned to the total amount of stains before cleaning. Specifically, before the experimental test, the weight G of the second cleaning rag in a clean state and the weight G1 of the second cleaning rag after absorbing the mud are measured. The difference between the two, that is, the weight of the absorbed mud △G1=G1-G. After performing the cleaning task for 5 minutes, the weight G2 of the second cleaning rag is measured at this time, and the weight of the cleaned stains is △G2=G1-G2. The stain cleaning rate P=(△G2 / △G1)*100% is calculated.

[0107] As described above, the relationship between the stain cleaning rate and the rotation speed of the second cleaning cloth is obtained by multiple measurements, such as Figure 8 As shown, when the second cleaning cloth rotates at 160 rpm, the stain cleaning rate will be significantly improved, from about 50% or less to about 70% or more, which can meet the cleaning requirements of the second cleaning cloth. With the further increase in the rotation speed, when the second cleaning cloth rotates at 260 rpm, the cleaning rate of the second cleaning cloth is basically close to 95%, which has almost completely cleaned the stains on the second cleaning cloth. When the second cleaning cloth rotates at more than 260 rpm, it will basically maintain the same stain cleaning rate. In addition, power consumption and noise will also increase significantly. Therefore, the roller brush rotation speed is maintained at 160-260 rpm, which can effectively clean the stains on the second cleaning cloth.

[0108] like Figure 8As shown, combined with the relationship diagram of the stain cleaning rate / life of the second cleaning rag and the rotation speed of the second cleaning rag given by the experiment, the relationship between the life of the second cleaning rag and the rotation speed of the second cleaning rag is further analyzed. In this experiment, the new and clean second cleaning rag is arranged at the base station, so that it rotates continuously to the same degree of wear. For example, the wear amount is calculated by the method as described above to determine whether it reaches the same degree of wear, thereby giving the service life of the second cleaning rag. Among them, the service life of the second cleaning rag refers to the use time of the second cleaning rag from a brand new state to a severely worn state, which is measured in units of accumulated hours of use. The severe wear state refers to giving a wear standard. Optionally, the second cleaning rag that is worn out by 60% is a severely worn state. The wear standard can locate other values ​​without strict limitation. As can be seen from the figure, the second cleaning rag has a basically stable service life at a low speed. When the rotation speed of the second cleaning rag reaches 160 rpm, the service life of the second cleaning rag begins to decline steadily. When the roller brush speed exceeds 260 rpm, the service life of the second cleaning rag decreases significantly. Therefore, the rotation speed of the second cleaning cloth is maintained at 160-260 rpm, which is the optimal rotation speed after combining the stain cleaning effect and service life.

[0109] In some embodiments, when 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 any rotation speed value such as 200 rpm, 210 rpm, 220 rpm, 230 rpm, etc. Figure 8 As shown, the cleaning rate of the second cleaning cloth has a relatively high stable range, and its service life also has a relatively high stable range.

[0110] During the normal cleaning process of the base station, as can be seen from the structural description of the second cleaning component in the above embodiment, the second cleaning component has a scraper rib 2123 and a protrusion 2125. The loss of the second cleaning rag per unit time is higher than that of the conventional floor. In order to maintain the relationship between the cleaning efficiency and the service life of the second cleaning rag, its rotation speed must be maintained in a stable and reasonable range, such as 160-260 rpm as mentioned above. Too low a rotation speed will cause too low cleaning efficiency, while too high a rotation speed will cause high damage to the second cleaning rag and will not increase the cleaning efficiency. Instead, it will generate greater noise and affect normal operation. Therefore, during the cleaning process, the second cleaning rag is rotated at a rotation speed within the above range, which can improve the cleaning effect without affecting the life of the second cleaning rag.

[0111] In some embodiments, Fig. 9 As shown, the distribution density of the protrusions is 1 / cm 2 -6 pieces / cm 2The pressure on the cleaning plate 212 is 3-10 Newtons. Under this pressure, the distribution density of the protrusions is set to 1 / cm 2 -6 pieces / cm 2 , which enables the second cleaning cloth to achieve the best cleaning effect. In the experiment, the cleaning rate definition process of the second cleaning cloth is as described above and will not be repeated here. In the experiment, a bearing pressure of 6 Newtons was selected, and the distribution density of the protrusions was 1 / cm 2 -16 pieces / cm 2 Test from Fig. 9 It can be seen that at low density, the density is 1 / cm 2 -6 pieces / cm 2 It has a high cleaning efficiency, basically maintaining a cleaning efficiency of more than 70%, and a density of more than 6 pieces / cm 2 When the particle size of the raised particles is not obvious, the decontamination effect is reduced.

[0112] In some embodiments, Fig.10 As shown, the height of the protrusion is 1mm-3mm, and the pressure on the cleaning plate 212 is 3-10 Newtons. Under this pressure, setting the height of the protrusion to 1mm-3mm can enable the second cleaning cloth to achieve the best cleaning effect. During the experiment, the cleaning rate definition process of the second cleaning cloth is as described above and will not be repeated here. During the experiment, a pressure of 6 Newtons was selected, and the height of the protrusion was tested at 0.5mm-5mm. Fig.10 It can be seen that as the height of the protrusion increases, the cleaning efficiency also increases. A height of 1mm-3mm has a relatively high and stable cleaning efficiency, basically maintaining a cleaning efficiency of more than 70%. When the height is too high, the cleaning efficiency is also very high, but the added value is not obvious, and a protrusion height that is too high will cause damage to the second cleaning cloth. Therefore, in order to balance the relationship between the two, it is ideal to choose a protrusion height of 1mm-3mm.
