Description

Technical Field

[0001] The utility model relates to the field of cleaning a cleaned area, in particular to a clean and effective cleaning device. Background Art

[0002] Most of the existing cleaning equipment only has dry suction function. For stubborn stains or sewage on the ground, dry suction cannot remove them and cannot provide users with a comprehensive and convenient use experience.

[0003] Some manufacturers have developed cleaning equipment with wet mopping capabilities, but sewage and dirt are sucked into a sewage tank using a suction pump. This typically requires significant power, resulting in high power consumption and frequent charging, which can be inconvenient for users and increase operating costs. Furthermore, the suctioned dirt can easily clog the suction port or channel, causing significant inconvenience. Furthermore, wet mopping prevents the complete removal of wastewater from the roller brush. If rinsed with clean water, the wastewater on the roller brush will contaminate the water, preventing the area from being properly cleaned or leaving a drag mark, severely impacting the user experience.

[0004] In response to the above-mentioned technical problems, this patent needs to provide a new technical solution. Utility Model Content

[0005] The purpose of this patent is to solve at least one of the problems in the existing technology.

[0021] As a preferred embodiment of the cleaning equipment described in this patent, it also includes a clean water tank,

[0022] The device's main body is equipped with a housing that covers the roller brush assembly. The housing has a water refill hole, which connects to the clean water tank via a clean water channel and a water supply motor. The water supply motor replenishes clean water from the clean water tank through the clean water channel and the water refill hole to the flexible cleaning layer of the roller brush assembly.

[0025] Compared with the existing technology, the technical solution described in this patent has at least one or more of the following beneficial effects:

[0026] This patented impeller and screw assembly features a clever design that not only rapidly transports wastewater to the sewage tank but also optimizes the device's mechanical structure, preventing wastewater from re-contacting the brush assembly and mixing with subsequent fresh water added to the brush assembly. The brush assembly uses a water supply motor to pump fresh water from the fresh water tank through a fresh water pipe to a water replenishment chamber. Fresh water is then replenished through the chamber's replenishment hole to the brush assembly's flexible cleaning layer. The impeller pushes wastewater from the brush assembly's flexible cleaning layer through a through-hole into the impeller's inner cavity. The wastewater within the cavity rotates with the impeller and, driven by a water-spinning rib, undergoes high-speed centrifugal rotation. The rib then ejects the wastewater through the through-hole into the screw housing. The screw rotates at high speed within the housing, where it, through a threaded assembly, pumps the wastewater from the housing in a bidirectional, helical, pressurized manner to the central sewage outlet. The water-spinning blades then eject the wastewater into the outlet. A certain amount of water pressure builds up within the screw housing, which in turn pumps the wastewater through the sewage channel into the sewage tank. The dirty water on the roller brush assembly can be removed in time, clean water can be added in time, the roller brush assembly can be cleaned in real time, and the cleaned area can be cleaned with a clean roller brush assembly in real time, making the cleaned area cleaner.

[0027] A pulsator rod is provided, which squeezes the flexible cleaning layer of the roller brush assembly, allowing the dirty water on the roller brush assembly to enter the interior of the pulsator rod more quickly without mixing with the clean water added to the roller brush assembly, making the roller brush assembly cleaner and facilitating cleaning. In addition, through the cooperation between the pulsator rod and the screw housing, the dirty water achieves high-speed centrifugal rotation in the inner cavity of the pulsator rod, is quickly thrown out of the pulsator rod, and enters the screw housing. It will not flow back into the surface of the roller brush assembly and will not participate in the interaction between the roller cotton and the dirty water.

[0028] The screw is provided with a first thread group and a second thread group, and adopts a double-line spiral conveying to increase the pressure to the sewage outlet and sewage channel in the middle, so that the sewage can be transported to the sewage tank faster; the sewage is concentrated at the sewage outlet for centralized transportation, which helps to reduce the volume of the equipment and makes the equipment flexible and convenient to use. This setting can optimize the structural design of the equipment body and avoid being cumbersome and heavy.

[0029] The high-speed rotation of the screw and its blades centrifugally spins the wastewater toward the wastewater outlet on the screw housing, where it is then swept into the outlet by the water-spinning blades. This eliminates the need for a suction motor to transport wastewater to the wastewater tank, significantly reducing power consumption, contributing to energy conservation and environmental protection, and making it more user-friendly.

[0030] The brush head group adopts a curved design, which allows the brush to contact the roller brush assembly at 360 degrees, making it easier to clean dirt on the roller brush assembly. At the same time, it makes the relative rotation of the brush and the roller brush assembly smoother, making the equipment more stable and preventing vibration.

[0031] The roller brush assembly is provided with a disassembly and assembly component to facilitate removal, cleaning, or replacement at any time. As is well known, the surface of the roller brush assembly is particularly easy to get dirty during use of cleaning equipment and needs to be cleaned or even replaced frequently. Therefore, a detachable roller brush assembly is provided without having to disassemble the transmission motor, making it easy to clean or replace the roller brush assembly at any time.

[0032] The present invention includes a roller brush detection structure that can detect whether there is water on the roller brush assembly, preventing the hard flexible cleaning layer, especially hard collodion, from cleaning the floor, making the cleaning device more intelligent. After the cleaning device is started, the roller brush detection structure first detects whether there is water on the roller brush. If there is water, it indicates that the collodion is soft and can be cleaned directly. If there is no water on the collodion, it indicates that the collodion roller brush is dry. The control module controls the water supply motor to supply water to the collodion. If the roller brush detection structure detects water on the collodion, the water supply motor stops supplying water to the collodion, and the cleaning device begins cleaning.

[0033] In addition, the special design of the brush group curve makes it difficult for dirt, especially hair, to be entangled on the brush group, and the brush can better scrape off dirt.

[0034] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

In the example, one through-hole group is provided between each two adjacent water-repelling ribs 314.

[0085] A pulsator rod is provided, which squeezes the flexible cleaning layer of the roller brush assembly, allowing the dirty water on the roller brush assembly to enter the interior of the pulsator rod more quickly without mixing with the clean water added to the roller brush assembly, making the roller brush assembly cleaner and facilitating cleaning. In addition, through the cooperation between the pulsator rod and the screw housing, the dirty water achieves high-speed centrifugal rotation in the inner cavity of the pulsator rod, is quickly thrown out of the pulsator rod, and enters the screw housing. It will not flow back into the surface of the roller brush assembly and will not participate in the interaction between the roller cotton and the dirty water.

[0086] In a preferred embodiment, Figure 4-5 、 Figure 7 and Figure 20-21 As shown, the screw assembly 4 is also included. The screw assembly 4 is arranged close to the pulsator rod. The screw assembly 4 includes a screw 41 and a screw housing 42. The screw 41 can be rotatably installed in the screw housing 42.

[0087] The screw 41 includes a screw body 411, a first thread group 412 and a second thread group 413. Along the length direction of the screw body 411, the first thread group 412 and the second thread group 413 are arranged on the screw body 411 in sequence. Along the direction from the end of the screw body to the middle of the screw body, the spiral direction of the threads on the first thread group and the second thread group are consistent with the rotation direction of the screw.

[0088] In the example, both ends of the screw 41 are rotatably mounted in the screw housing 42 via bearings.

[0089] Preferably, Figure 4-7 and Figure 24As shown, the screw housing 42 is connected to the pulsator housing 32, and the screw 41 is configured to transfer the sewage on the roller brush assembly 2 removed by the pulsator 31 to the sewage outlet 421. Preferably, the screw assembly 4 is arranged on the side of the pulsator assembly 3 close to the sewage tank 6. Preferably, the pulsator housing 32 and the screw housing 42 are designed as one piece. In the example, the pulsator housing 32 and the screw housing 42 are both designed as one piece on the housing 11 of the device body.

[0090] Preferably, Figure 4 、 Figure 7 and Figure 24 As shown, the screw 41 is close to or attached to the inner wall of the screw housing 42. The clearance between the first and second thread groups of the screw 41 and the inner wall of the screw housing 42 in this patent is less than 5 mm, preferably less than 1 mm, and more preferably 0.2-0.5 mm. If the clearance between the edge of the thread and the inner wall of the screw housing is too large, the screw will not be able to effectively transport sewage during rotation. If the clearance between the edge of the thread and the inner wall of the screw housing is too small, for example, if the edge of the thread is tangent to or in contact with the inner wall of the screw housing, friction will increase, which will also affect transportation.

[0091] Preferably, the screw housing 42 is provided with a sewage outlet 421 and an access port 422. The length direction of the access port 422 is consistent with the length direction of the screw 41, and the access port 422 faces the direction of the impeller rod. In the example, the access port of the screw housing 42 corresponds to the second opening of the impeller rod housing 32. In the example, the second opening faces the direction of the screw 41. In the example, the sewage outlet 421 is set at a position corresponding to the middle of the screw. In the example, the sewage outlet 421 is connected to the sewage tank 6 through the sewage channel 61. Preferably, the sewage channel 61 is sealed to the sewage tank 6. In the example, the sewage outlet is set on the side of the screw housing 42 away from the impeller rod 31. In the example, the sewage in the inner cavity of the roller rod is thrown out through the through hole and passes through the second opening and the access port in sequence into the screw housing. The screw rotates in the screw housing and transports the sewage in the screw housing to the sewage outlet along the direction of the thread, and then transports it to the sewage tank through the sewage channel. In this example, the screw housing 42 has a semi-enclosed structure, with the angle between the housing and the screw on one side of the inlet greater than 180 degrees. This semi-enclosed structure, in which the housing and the screw cooperate to form a sewage transfer mechanism, significantly differs from existing technologies in both its transfer principle and effectiveness. It also offers relatively low costs and eliminates the need for a pumping module.

[0092] Preferably, Figure 20-21 As shown, the first thread group 412 and the second thread group 413 are symmetrically arranged on the screw body 411. In this example, the spiral directions of the first thread group 412 and the second thread group 413 are opposite.

[0093] Preferred examples include Figure 20-21As shown, the screw body 411 is further provided with a water-spinning blade 414, which is disposed between the first thread group 412 and the second thread group 413. As the screw rotates, the water-spinning blade 414 is configured to spin the sewage at the water-spinning blade into the sewage outlet 421. In this example, the water-spinning blade 414 is disposed corresponding to the sewage outlet 421, and the length of the sewage outlet 421 is consistent with that of the water-spinning blade 414.

[0094] Preferably, Figure 20-21 As shown, the water-repelling blade 414 is consistent with the length direction of the screw body 411. Further preferably, the water-repelling blade 414 is an arc-shaped water-repelling blade, and the opening direction of the concave middle part of the water-repelling blade 414 is consistent with the rotation direction of the screw 41.

[0095] Further, such as Figure 20-21 As shown, the screw body 411 is provided with a plurality of water-spinning blades 414 along the circumferential direction. Further preferably, the plurality of water-spinning blades 414 are arranged at equal intervals. In this example, the screw body 411 is provided with two water-spinning blades 414 along the circumferential direction, one end of which is connected to the first thread group 412, and the other end of which is connected to the second thread group 413. Of course, this patent is not limited to this embodiment, and a different number of water-spinning blades can be provided according to actual needs.

[0096] In the example, the sewage on the flexible cleaning layer of the roller brush assembly 2 is squeezed by the impeller rod 31, and the sewage enters the inner cavity 313 of the impeller rod through the through hole 312. The sewage in the inner cavity 313 follows the rotation of the impeller rod and is pushed by the water-throwing ribs to perform high-speed centrifugal rotation. The water-throwing ribs 314 throw the sewage in the inner cavity 313 out into the screw housing 42 through the through hole 312. The screw 41 rotates at a high speed in the screw housing. The screw 41 conveys the sewage in the screw housing 42 to the middle sewage outlet in a bidirectional spiral pressurized manner through the thread group, and throws the sewage into the sewage outlet 421 through the water-throwing blades. There is a certain water pressure in the screw housing, and the sewage is transported to the sewage tank through the sewage channel by the water pressure in the screw housing.

[0097] The screw is provided with a first thread group and a second thread group, and adopts a double-line spiral conveying to increase the pressure to the sewage outlet and sewage channel in the middle, so that the sewage can be transported to the sewage tank faster; the sewage is concentrated at the sewage outlet for centralized transportation, which helps to reduce the volume of the equipment and makes the equipment flexible and convenient to use. This setting can optimize the structural design of the equipment body and avoid being cumbersome and heavy.

[0098] The high-speed rotation of the screw and its blades centrifugally spins the wastewater toward the wastewater outlet on the screw housing, where it is then swept into the outlet by the water-spinning blades. This eliminates the need for a suction motor to transport wastewater to the wastewater tank, significantly reducing power consumption, contributing to energy conservation and environmental protection, and making it more user-friendly.

[0099] Preferably, the impeller rod 31 rotates actively or passively.

[0100] In one example, the pulsator rod 31 is connected to a driving motor, and the pulsator rod 31 rotates under the drive of the driving motor. Preferably, under the drive of the driving motor, the rotation direction of the pulsator rod 31 is opposite to the rotation direction of the roller brush assembly 2.

[0101] In one example, the pulsator rod 31 passively rotates in the opposite direction following the roller brush assembly 2. Preferably, the pulsator rod 31 is connected to the roller brush assembly 2 through gear meshing or belt connection, but this patent is not limited to this. Figure 3 As shown, the pulsator rod 31 is connected to the roller brush assembly 2 through gear meshing and passively rotates following the roller brush assembly 2.

[0102] Preferably, the screw 41 rotates actively or passively.

[0103] In one example, the screw 41 is connected to a drive motor, and the screw 41 rotates under the drive motor. Preferably, under the drive motor, the rotation direction of the screw 41 is opposite to the rotation direction of the pulsator rod 31.

[0104] In one example, the screw 41 passively rotates in the opposite direction following the pulsator rod 31.

Figure 3 As shown, the screw 41 is connected to the pulsator rod 31 through gear meshing, and the pulsator rod 31 is connected to the roller brush assembly 2 through gear meshing. The roller brush assembly 2 rotates under the drive of the transmission motor, which in turn drives the pulsator rod 31 and the screw 41 to passively rotate. Of course, the screw 41 can also be directly connected to the roller brush assembly and rotate under the drive of the roller brush assembly, which will not be described in detail in this patent.

[0105] In a preferred embodiment, a brush assembly 5 is also included; the brush assembly 5 includes a brush 51, the brush 51 includes a brush rod 511 and a brush head 512 arranged on the brush rod, the brush 51 is close to or fitted with the roller brush assembly 2, and the brush 51 is configured to scrape off dirt on the roller brush assembly 2.

[0106] Preferably, Figure 4-5 、 Figure 7 and Figure 22As shown, the brush assembly 5 also includes a brush housing 52, and the brush 51 is rotatably installed in the brush housing 52. Further preferably, it also includes a dirt box 7, which is arranged below the brush 51, and the dirt box 7 can hold the dirt scraped off by the brush 51. In the example, one opening of the brush housing 52 faces the roller brush assembly 2, and one opening of the brush housing 52 faces the dirt box 7. Preferably, the dirt box 7 is detachably installed on the device body 1, so as to facilitate timely dumping of the dirt in the dirt box. In the example, the dirt box 7 is arranged between the roller brush assembly 2 and the sewage tank 6. However, this patent is not limited to this. The dirt box 7 and the sewage tank 6 can be installed horizontally side by side or vertically side by side on the rear side of the roller brush assembly 2, depending on the convenience of installation or use.

[0107] In the example, both ends of the brush 51 are rotatably mounted in the brush housing 52 via bearings.

[0108] More preferably, Figure 4 and Figure 7 As shown, the brush assembly 5 and the pulsator rod assembly 3 are sequentially arranged along the rotation direction of the roller brush assembly 2. In this example, the pulsator rod assembly 3 is arranged above the roller brush assembly 2, and the brush assembly 5 is arranged on the side of the roller brush assembly 2 close to the sewage tank 6. In this example, the screw assembly 4 is arranged on the side of the pulsator rod assembly 3 close to the sewage tank 6. In this example, the screw assembly 4 is arranged between the pulsator rod assembly 3 and the brush assembly 5.

[0109] More preferably, Figure 22 As shown, a plurality of brush heads 512 form a brush head group 513 along the length of the brush rod 511. The brush head group 513 is a curved brush head group and is provided with a raised section 514. The raised section 514 protrudes in the opposite direction of rotation of the brush rod 511. In the example, the raised section 514 is provided in the middle of the brush head group 513. Further preferably, multiple groups of brush head groups 513 are provided at intervals along the circumferential direction on the surface of the brush 51. Even more preferably, multiple groups of brush head groups are provided at equal intervals along the circumferential direction on the brush 51. In the example, four groups of brush head groups are provided at equal intervals along the circumferential direction on the brush 51.

[0110] The brush head group adopts a curved design, which allows the brush to contact the roller brush assembly at 360 degrees, making it easier to clean dirt on the roller brush assembly. At the same time, it makes the relative rotation of the brush and the roller brush assembly smoother, making the equipment more stable and preventing vibration.

[0111] Preferably, the brush 51 rotates actively or passively.

[0112] In one example, the brush 51 is connected to a drive motor, and the brush 51 rotates under the drive motor. Preferably, under the drive motor, the rotation direction of the brush 51 is opposite to or the same as the rotation direction of the roller brush assembly 2.

[0113] In one example, the brush 51 rotates passively following the screw 41 or the roller brush assembly 2.

As the roller brush assembly 2 rotates, the pulsator rod 31, the screw 41, the first gear 53 and the brush 51 are driven to rotate in sequence. In the example, the rotation direction of the brush 51 is the same as the rotation direction of the roller brush assembly 2. Of course, the brush 51 can also be directly connected to the roller brush assembly and rotated under the drive of the roller brush assembly, which will not be described in detail in this patent.

[0114] In a preferred embodiment, Figure 1 As shown, the device further comprises an operating rod 9, which is rotatably connected to the device body 1. Preferably, the clean water tank 8 is detachably mounted on the operating rod 9.

[0115] In a preferred embodiment, Figure 2-7 As shown, the roller brush assembly 2 is detachably mounted on the device body. Preferably, a button is provided, by pressing the button, at least one end of the roller brush assembly 2 can be taken out from the device body.

[0116] In the example, Figure 12 As shown, the roller brush body 21 is provided with a second accommodating cavity 216 and a second roller brush opening 217 , and the second accommodating cavity 216 is communicated with the second roller brush opening 217 .

[0117] Preferably, Figure 10-11 As shown, the second accommodating cavity 216 contains a disassembly component 23 , which is installed on the device body 1 . By pressing the disassembly component 23 , the roller brush assembly 2 is removed from the device body 1 .

[0118] Preferably, Figure 13-15As shown, the disassembly and assembly component 23 includes a fixing seat 231, an elastic member 232, and a pressing member 233. The fixing seat 231 is fixedly installed in the second accommodating chamber 216. The fixing seat 231 is provided with an accommodating chamber 2311 and an installation opening 2312. The elastic member 232 is accommodated in the accommodating chamber 2311. One end of the elastic member 232 is in contact with the accommodating chamber 2311, and the other end of the elastic member 232 is in contact with the pressing member 233. A stopper 2331 is provided on the surface of the pressing member 233, and the stopper 2331 can prevent the pressing member 233 from being removed from the accommodating chamber 2311. In this example, the elastic member 232 is a spring, one end of the spring is in contact with the bottom of the accommodating chamber 2311, and the other end of the spring is in contact with the side of the stopper 2331. In this example, the outer diameter of the spring is not larger than the inner diameter of the accommodating chamber 2311, and the inner diameter of the spring is smaller than the outer diameter of the stopper 2331.

[0119] More preferably, Figure 10 and Figure 13-14 As shown, the fixing seat 231 includes a base 2313 and a cover plate 2314. The base 2313 is fixedly installed in the second accommodating chamber 216. The spring and the pressing member 233 are sequentially accommodated in the accommodating chamber 2311. One end of the pressing member 233 extends out of the accommodating chamber 2311. The cover plate 2314 is provided with a mounting opening 2312. The cover plate 2314 is inserted into the pressing member 233 through the mounting opening 2312. The stopper 2331 is located on the side of the cover plate 2314 close to the base 2313. The cover plate 2314 is fixedly connected to the base 2313. In the example, the cover plate 2314 is threadedly connected to the base 2313. Of course, it can also be snap-fitted, welded, etc., which is not limited by this patent. In the example, the inner diameter of the mounting opening 2312 is smaller than the outer diameter of the stopper 2331.

[0120] Preferably, Figure 10-12 As shown, the bottom of the second accommodating cavity 216 is a fixing frame 215, and the base 2313 is fixedly mounted on the fixing frame 215. In this example, the base 2313 is threadedly connected to the fixing frame 215.

[0121] More preferably, Figure 13As shown, a button 234 is installed on the pressing member 233. In the example, the button 234 is threadedly installed on the pressing member 233. When the button is not pressed, the button extends out of the roller brush body, and a first roller brush groove 115 is provided on the shell 11. The button 234 is rotatably installed in the first roller brush groove 115 through a bearing. In the example, the first roller brush groove 115 is provided on the side wall of the shell body. Preferably, a second roller brush cover 235 is also provided on the disassembly component 23, and the second roller brush cover 235 is provided on the cover plate 2314, or on the pressing member 233, or on the button 234. In the example, the second roller brush cover 235 is provided on the button 234, and the outer diameter of the second roller brush cover 235 is consistent with the inner diameter of the second accommodating cavity 216. In the example, a first roller brush groove is provided on the side wall of the device body, and a button on the roller brush body is rotatably installed in the first roller brush groove through a bearing. A device button is also provided at the bottom of the first roller brush groove. The device button corresponds to the button on the disassembly component. When the device button is pressed, the button on the disassembly component is pressed synchronously, the button is moved out of the first roller brush groove, and the roller brush assembly can be taken out from the device body.

[0122] When button 234 is pressed, it moves toward second accommodating cavity 216 and out of first roller brush slot 115, removing the roller brush body, covered with the flexible cleaning layer, from the device body. In this example, the transfer motor and first roller brush cover are both fixedly connected to the second end cap. The transfer motor and first roller brush cover are not removed from the device body with the roller brush body; the disassembly components and the flexible cleaning layer are removed from the device body along with the roller brush body.

[0123] The roller brush assembly is provided with a disassembly and assembly component to facilitate removal, cleaning, or replacement at any time. As is well known, the surface of the roller brush assembly is particularly easy to get dirty during use of cleaning equipment and needs to be cleaned or even replaced frequently. Therefore, a detachable roller brush assembly is provided without having to disassemble the transmission motor, making it easy to clean or replace the roller brush assembly at any time.

[0124] In a preferred embodiment, the roller brush assembly is provided with a roller brush detection structure capable of detecting whether the flexible cleaning layer on the roller brush assembly is wet. In a further preferred embodiment, the flexible cleaning layer is collodion, and the roller brush detection structure is disposed in contact with the collodion, capable of detecting whether the collodion is wet. As is well known, collodion hardens after being left dry for a long time and only softens after being watered. Therefore, the roller brush detection structure is provided to detect whether the collodion brush is wet before the cleaning device begins cleaning. If no water is present, the collodion brush is pre-filled with water before cleaning the floor or surface, thereby preventing the hard collodion brush from being unable to clean. In one embodiment, the roller brush detection structure is a conductive contact. At least one set of conductive contacts is provided on the device body, each set of conductive contacts comprising two spaced apart conductive contacts. The two conductive contacts are each connected to the power module via a wire, and the presence of water in the collodion is detected by the electrical conduction between the two conductive contacts. Both conductive contacts in each set of conductive contacts are in contact with the collodion. When there is no water on the collodion roller brush, the two conductive contact heads cannot form a closed circuit and the detected resistance is very large; when there is water on the collodion roller brush, the two conductive contact heads form a closed circuit and the detected resistance becomes smaller.

[0125] Working principle: The control module sets the upper limit value. When the cleaning equipment is in use, the control module controls the roller brush detection structure to detect the resistance value. If the resistance value is greater than the upper limit value, it means that there is no water on the rubber cotton roller brush, and the rubber cotton cannot clean the floor at this time; the control module controls the clean water tank to supply water to the rubber cotton; when the roller brush detection structure detects that the resistance value is less than the lower limit value, it means that the rubber cotton is replenished with water or there is water on the rubber cotton roller brush, that is, the rubber cotton is soft and can be used to clean the floor. At this time, the control module controls the clean water tank to stop supplying water to the rubber cotton roller brush or the cleaning equipment starts the cleaning mode.

[0126] Of course, the roller brush detection structure can also be a sensor, which is arranged in contact with the collodion roller brush of the roller brush assembly, and the sensor can detect whether there is water on the collodion roller brush. The sensor includes a water immersion sensor or other detection sensors, etc.

[0127] The present invention includes a roller brush detection structure that can detect whether there is water on the roller brush assembly, preventing the hard flexible cleaning layer, especially hard collodion, from cleaning the floor, making the cleaning device more intelligent. After the cleaning device is started, the roller brush detection structure first detects whether there is water on the roller brush. If there is water, it indicates that the collodion is soft and can be cleaned directly. If there is no water on the collodion, it indicates that the collodion roller brush is dry. The control module controls the water supply motor to supply water to the collodion. If the roller brush detection structure detects water on the collodion, the water supply motor stops supplying water to the collodion, and the cleaning device begins cleaning.

[0128] It should be noted that, in the absence of conflict, all technical features of the above cleaning equipment can be freely combined, and their free combination or simple variation, change and modification are all within the scope of protection of this patent.
