Description

Priority note

[0001] This disclosure claims priority from patent applications No. 202423200305.5 (filed on December 21, 2024) and No. 202521920367.5 (filed on September 5, 2025) at the Chinese Patent Office (CNIPA), the entire contents of which are hereby incorporated by reference. Technical area

[0002] The present disclosure relates to the technical field of cleaning and in particular to a recycling assembly, a cleaning module, a cleaning device, a cleaning base station and a cleaning system. State of the art

[0003] The cleaning device cleans the surface by rotating it through the mop and wiper element. The cleaning device is further equipped with a recycling element that rests against the mop and wiper element. As the mop and wiper element rotates, the first sludge scraper section of the recycling element scrapes the sludge from the mop and wiper element and collects it in the sludge collection chamber of the recycling element. However, the recycling element requires a support section on at least one side along its length to provide space for the installation of other components of the recycling element, such as a drain pipe or other cleaning device components. The drain pipe is designed to connect to the sludge collection chamber to discharge the wastewater either to the outside or into the cleaning device's wastewater tank.The design of this alternative space makes it difficult to install a sludge collection chamber or limits the capacity of the sludge collection chamber, which means that the sludge scraped off by the sludge scraper section cannot directly enter the sludge collection chamber, or the small capacity of the sludge collection chamber impairs the wastewater flow rate, leading to wastewater accumulation and consequently water leakage from the cleaning device.

[0057] The cleaning device cleans the surface to be cleaned by rotating the mop and wiper element. The first sludge scraper section of the recycling element scrapes the sludge from the mop and wiper element and collects it in the sludge collection chamber. However, a support section must be arranged along one side of the recycling element in its longitudinal direction to provide space for the installation of wastewater pipes and other structures. The wastewater pipe is connected to the sludge collection chamber and is designed to discharge wastewater. The arrangement of this support section makes it difficult to construct a sufficiently large sludge collection chamber, which either prevents the scraped sludge from entering the chamber directly or impairs the wastewater flow rate, leading to wastewater accumulation and, consequently, water leakage from the cleaning device.To solve this problem, the present disclosure presents a recycling assembly 100 (see . Fig. 4), a cleaning module 1000 (see Fig. 4), a cleaning device 10001 (see Fig. 2 and Fig. 3), a cleaning base station 10003 (see Fig. 1) and a cleaning system 10000 (see Fig. 1) ready.

[0058] As in the Fig. 1 and Fig. As shown in Figure 2, the cleaning system 10000 described in this disclosure comprises a cleaning device 10001 and / or a cleaning base station 10003 according to one of the following embodiments.

[0059] The cleaning device 10001 is designed to clean a surface. For example, the cleaning device 10001 can include a mopping robot and a mopping and sweeping robot. The mopping robot can be used to mop and clean the surface, while the mopping and sweeping robot combines the functions of both types of robots; it can therefore be used for both sweeping and mopping and cleaning the surface. The cleaning device 10001 described herein is illustrated using a vacuuming and mopping robot as an example. The surfaces to be cleaned can be, for example, floors, marble surfaces, carpets, or glass surfaces. This description uses a floor for illustrative purposes.

[0060] The cleaning base station 10003 is used for the maintenance of the returning cleaning device 10001. The cleaning base station 10003 can, for example, clean and recharge the cleaning device 10001. In addition, the cleaning base station 10003 can also have at least one of the following functions: charging, refilling with water, emptying, and dust extraction for the cleaning device 10001. For example, the cleaning base station 10003 has a first electrical connection, and the cleaning device 10001 has a second electrical connection. When the cleaning device 10001's battery is low, the cleaning base station 10003 recharges the cleaning device 10001 when it is inserted into the base station 10003 and the first electrical connection is connected to the second.When the cleaning device 10001 is fully charged, it can leave the cleaning base station 10003 and continue cleaning the surface. When the cleaning device 10001 needs to drain water, it returns to the cleaning base station 10003 to empty the wastewater and then leaves the cleaning base station 10003 to continue cleaning the surface.

[0061] The cleaning device 10001 and the cleaning base station 10003 are described in detail below with reference to the attached drawings.

[0062] As in Fig. As shown in Figure 3, the cleaning device 10001 comprises a cleaning module 1000, a device body 3000, a roller brush 5000, a side brush 7000, and a water spray bar 9000. The cleaning module 1000 is arranged on the device body 3000. The mop and wiper element 300 is designed to rotate and wipe the surface to be cleaned. The device body 3000 is provided with a suction opening 3001 and a sludge chamber (not shown). The suction opening 3001 is connected to the sludge chamber and the outside of the cleaning device 10001. The cleaning device 10001 further comprises a roller brush 5000 and / or a side brush 7000. The roller brush 5000 is installed at the suction opening 3001 of the device body 3000. The roller brush 5000 rotates relative to the device body 3000 to transport the sludge from the surface to be cleaned into the sludge chamber. The side brush 7000 is mounted on the device body 3000.In the direction of travel M of the cleaning device 10001, the side brush 7000 is located in front of the suction opening 3001. The side brush 7000 rotates relative to the device body 3000 in order to convey the sludge on the surface to be cleaned to the roller brush 5000 and / or to the suction opening 3001.

[0063] The cleaning module 1000 is a module of the cleaning device 10001 that contributes to the cleaning of the surface to be cleaned by providing a tensile force. The cleaning module 1000 comprises a recycling assembly 100 and a mop and wiper element 300. The recycling assembly 100 comprises a housing 30, and the mop and wiper element 300 is arranged on the housing 30.

[0064] The housing 30 is a component designed to accommodate other components (such as the mop and wiper element 300) within the cleaning module 1000, with the exception of the housing 30 itself. The mop and wiper element 300 is part of the cleaning module 1000 and, in particular, provides the mopping and wiping force required to clean the surface. The mop and wiper element 300 is arranged on the device body 3000 in the following manner: The housing 30 is either detachably or permanently mounted on the device body 3000, and the mop and wiper element 300 is either detachably or permanently mounted on the housing 30, thereby indirectly attaching the mop and wiper element 300 to the device body 3000.

[0065] In the embodiments of the present disclosure, the mop and wiper element 300 is a tracked mop, in which case the cleaning device 10001 is a tracked cleaning device. In some other embodiments, the mop and wiper element 300 is a roller mop and wiper element 300, in which case the cleaning device 10001 is a roller cleaning device. In some further embodiments, the mop and wiper element 300 can be a flat mop and wiper element 300 or a rotating disc mop and wiper element, in which case the cleaning device 10001 can be a flat cleaning device or a rotating disc cleaning device. Regardless of the type of mop and wiper element 300, the mop and wiper element 300 will always come into contact with the surface to be cleaned when the cleaning module 1000 cleans the surface to be cleaned.Whether it's a rotating disc mop and wiper element, a tracked mop and wiper element, or a roller mop and wiper element – ​​all mop and wiper elements rotate relative to the surface being cleaned. During the rotation of the mop and wiper element, it can roll or wipe the dirt off the surface, thus keeping it clean. The dirt can contain both liquid and solid debris. Track-guided mops include, among others, disposable electrostatic mops, disposable wet mops, and reusable cloth mops.

[0066] All components of the cleaning device 10001, with the exception of the device body 3000, are mounted on the device body 3000. That is, the device body 3000 serves as a carrier and can accommodate all components of the cleaning device 10001, with the exception of the device body 3000.

[0067] The roller brush 5000 is attached to the suction opening 3001 of the device body 3000 and is designed to roll up the sludge from the surface to be cleaned and transport it into the sludge chamber by rotating relative to the device body 3000. The sludge passes through the suction opening 3001 and the sludge chamber and finally enters the dust container inside the device body 3000. For example, the roller brush 5000 can comprise a roller body and a brush body, wherein the roller body of this disclosure has a cylindrical structure and the brush body has a helical structure extending along the axial direction of the roller body. The brush body can consist of a rubber strip, a bristle strip, or a combination of rubber strips and bristle strips. The number of brush bodies can be, but need not be, one, two, three, four, or more.With multiple brush bodies, the brush bodies are spaced apart on the roller body. Thanks to its spiral brush body, the 5000 roller brush can accumulate and collect sludge more effectively, resulting in higher cleaning efficiency. Furthermore, the spiral brush body provides a larger contact area with the surface being cleaned per unit of time, improving coverage and cleaning performance.

[0068] The side brush 7000 can assist the roller brush 5000 in cleaning, and the side brush 7000 is able, by rotating relative to the device body 3000, to transport the sludge from the surface to be cleaned to the roller brush 5000 and / or to the suction opening 3001, with the sludge passing through the suction opening 3001 and the sludge chamber into the dust container. If the cleaning device 10001 comprises a mop and wiper element 300 and a side brush 7000, the cleaning device 10001 achieves a better cleaning effect on the surface to be cleaned. Preferably, at least a portion of the side brush 7000 can extend from the circumference of the device body 3000, enabling the side brush 7000 to reach areas that are difficult for the mop and wiper element 300 to access, such as walls, corners, or crevices. The side brush 7000 extends the cleaning area of ​​the cleaning device 10001 (e.g.a cleaning robot), whereby the cleaning robot cleans the surface more thoroughly, thus achieving a better cleaning result.

[0069] The water spray bar 9000 can be arranged on one side of the cleaning module 1000. For example, the water spray bar 9000 can be arranged on the front of the cleaning module 1000 in the direction of travel M of the cleaning device 10001 and attached to the front part of the housing 30 of the cleaning module 1000. The water spray bar 9000 has several water spray nozzles spaced axially (i.e., in the longitudinal direction X) of the axis of rotation S of the mop and wiper element 300 and directed towards the mop and wiper element 300, so that the liquid sprayed from the water spray bar 9000 can flow to the mop and wiper element 300.

[0070] As in the Fig. 3, Fig. 4, Fig. 5 to Fig. As shown in Figure 6, this disclosure provides a recycling assembly 100. The recycling assembly 100 is used in the cleaning device 10001. The cleaning device 10001 comprises a mop and wiper element 300, wherein the mop and wiper element 300 is a tracked mop and the mop and wiper element 300 cleans a surface to be cleaned by rotating in a first direction R. The recycling assembly 100 comprises a recycling element 10 and a housing 30. The recycling element 10 comprises a main body section 11, a first sludge scraper section 13, and a support section 15. The first sludge scraper section 13 is arranged on the main body section 11 and rests against the mop and wiper element 300. While the mop and wiper element 300 rotates in a first direction R to clean the surface to be cleaned, the first mud scraper section 13 removes the mud from the mop and wiper element 300.The main body section 11 is provided with a sludge collection chamber 111, the sludge collection chamber 111 being designed to collect the sludge scraped off by the mop and wiper element 300 during cleaning of the surface to be cleaned. The support section 15 is located longitudinally X at least on one side of the main body section 11. The mop and wiper element 300 and the recycling element 10 are connected to the housing 30. The housing 30 is provided with a second sludge scraper section 31, the second sludge scraper section 31 bearing against the mop and wiper element 300.As the mop and wiper element 300 rotates in the first direction R to clean the surface to be cleaned, at least part of the second sludge scraper section 31 is located upstream of the support section 15, whereby part of the sludge rolled from the surface to be cleaned by the mop and wiper element 300 is scraped off by the second sludge scraper section 31 before it rotates to the area corresponding to the support section 15.

[0071] The recycling element 10 is designed to collect and temporarily store the wastewater generated by the mop and wiper element 300 during the cleaning of the surface to be cleaned. The wastewater in the recycling element 10 can be stored in the wastewater box 500 of the cleaning device 10001, whereby the wastewater in the wastewater box 500 can also enter the recycling element 10 and subsequently be discharged from there to the outside. The recycling element 10 is arranged on the device body 3000 in the following ways: The recycling element 10 is detachably or permanently mounted on the device body 3000, and the recycling element 10 is detachably mounted on the housing 30, thereby indirectly attaching the recycling element 10 to the device body 3000.

[0072] The main body section 11 is designed to support and connect other components outside of the main body section 11. When the cleaning device 10001 is in operation, the main body section 11 remains fixed. The main body section 11 can be made of plastic, metal, or composite material; however, this disclosure is not limited to these materials. If the material of the main body section 11 is plastic, the main body section 11 has good insulating properties, low cost, and light weight. If the material of the main body section 11 is metal, the main body section 11 has high strength, good wear resistance, and a long service life.

[0073] The first sludge scraper section 13 rests against the mop and wiper element 300 to remove sludge from the mop and wiper element 300. During operation of the cleaning device 10001, the first sludge scraper section 13 rests against the mop and wiper element 300, which rotates in the first direction R, i.e., downwards relative to the first sludge scraper section 13. The first sludge scraper section 13 scrapes the sludge from the clean surface of the mop and wiper element 300, thus reducing sludge deposits on the mop and wiper element 300.

[0074] The main body section 11 is provided with a sludge collection chamber 111, which is designed to temporarily store the wastewater generated by the mop and wiper element 300 during the wiping process. The sludge collection chamber 111 can be cuboid, cylindrical, or have another shape. The sludge collection chamber 111 is either open-topped or closed-topped. For open-topped chambers, the upper part of the recycling assembly 10 has an opening, allowing the sludge collection chamber 111 to be directly connected to the outside, thus facilitating cleaning. In closed-topped chambers, there is no opening above the recycling assembly 10, and the sludge collection chamber 111 forms a completely enclosed structure above it, providing a better seal and preventing wastewater from escaping during the recycling process.During the cleaning process of the surface to be cleaned by the cleaning device 10001, the first sludge scraper section 13 removes the sludge from the mop and wiper element 300, and the sludge collection chamber 111 is able to retain the wastewater in the sludge, thus preventing the wastewater from adhering to the mop and wiper element 300 again or from reaching the surface to be cleaned. Furthermore, the inner wall of the sludge collection chamber 111 can be treated to prevent sludge accumulation, for example, by using a smooth material or a coating. The combination of the sludge container 111 and the first sludge scraper section 13 allows the wastewater contained in the sludge to be temporarily stored in the sludge collection chamber 111 after the sludge has been scraped by the first sludge scraper section 13, thus preventing the wastewater from overflowing or adhering to the mop and wiper element 300 again.In some embodiments, the sludge collection chamber 111 extends along the axis of rotation S of the mop and wiper element 300, which on the one hand increases the collection space of the sludge collection chamber 111 and on the other hand enables more effective use of the interior of the cleaning device 10001, so that mutual interferences between the recycling element 10 and the mop and wiper element 300 are reduced and the arrangement along the axis of rotation S of the mop and wiper element 300 is made more compact, thus making optimal use of the interior of the cleaning device 10001.

[0075] The support section 15 is located on at least one side of the longitudinal direction X of the main body section 11. The support section 15 is designed to provide space for the installation of other structures of the recycling element 10 or other structures of the cleaning device 10001, the other structures being described in more detail later (wastewater pipe, second wastewater outlet 183 of the cleaning device 10001, or part of the sludge collection chamber 111). In the direction of travel M of the cleaning device 10001, the mop and wiper element 300 is arranged on one side of the support section 15, while the other side of the support section 15 can be designed for mounting other structures of the recycling element 10 or other structures of the cleaning device 10001.As the mop and wiper element 300 rotates in the primary direction R to clean the surface, the support section 15 isolates the mop and wiper element 300 from other structures. This prevents the mop and wiper element 300 from interfering with other structures and ensures the installation stability of those structures. The support section 15 is typically elongated or plate-shaped. Its size and shape can be designed according to the length of the primary sludge scraper section 13. For example, the thickness of the support section 15 (its dimension perpendicular to the vertical direction Z and the longitudinal direction X) can be reduced, thus creating space for the installation of other structures.

[0076] A second sludge scraper section 31 is arranged on the housing 30. During the cleaning process of the mop and wiper element 300 on the surface to be cleaned, and as the mop and wiper element 300 rotates in the first direction R, i.e., as the mop and wiper element 300 rotates downwards relative to the second sludge scraper section 31, the second sludge scraper section 31 scrapes the sludge from the clean surface of the mop and wiper element 300, thus reducing the sludge deposits on the mop and wiper element 300. At least part of the second sludge scraper section 31 is located upstream of the support section 15.The term “upstream” means that the part of the mop and wiper element 300 that is in contact with the surface to be cleaned first passes through the second sludge scraper section 31 and then the support section 15 after contact with the surface, whereby some of the sludge rolled from the surface to be cleaned by the mop and wiper element 300 is scraped off by the second sludge scraper section 31 before it rotates to the area corresponding to the support section 15.

[0077] In the recycling assembly 100 described herein, sludge forms on the mop and wiper element 300 during the process in which the mop and wiper element 300 rotates in the first direction R to clean the surface to be cleaned. The first sludge scraper section 13 rests against the mop and wiper element 300, and some of the sludge on the clean surface of the mop and wiper element 300 can be scraped off by the first sludge scraper section 13.The second sludge scraper section 31 is located on the mop and wiper element 300, and at least part of the second sludge scraper section 31 is located upstream of the support section 15, so that the sludge on the cleaning surface of another part of the mop and wiper element 300 is scraped off by the second sludge scraper section 31 before it rotates to the area corresponding to the support section 15, thereby reducing the amount of sludge reaching the support section, preventing an accumulation of wastewater in the support section 15, and thus avoiding water leakage from the cleaning device 10001 and improving the reliability of the cleaning device 10001.

[0078] As in the Fig. 3, Fig. 5 and Fig. As shown in Figure 6, in certain embodiments of a rotary system whose center point is a point on the axis of rotation S of the mop and wiper element 300 and whose reference line forms the vertical direction Z of the cleaning device 10001, the mounting angle position A1 of the second sludge scraper section 31 precedes the mounting angle position A2 of the support section 15 in the first direction R. In the axial direction of the axis of rotation S of the mop and wiper element 300 (in the longitudinal direction X), the extended coverage area D2 of the support section 15 lies within the extended coverage area D1 of the second sludge scraper section 31.

[0079] More precisely, the mounting angle position refers to the relative position of a component with respect to a fixed center of rotation and a fixed reference line in a rotating system. For example, the center of rotation is a point on the axis of rotation S of the mop and wiper element 300, and the vertical direction Z of the cleaning device 10001 is a reference baseline. The mop and wiper element 300 rotates about the first direction R, while other components, such as the second sludge scraper section 31 and the support section 15, are arranged about the axis of rotation S of the wiping component of the mop and wiper element 300.The mounting angle position A1 of the second sludge scraper section 31 is the angle of the second sludge scraper section 31 relative to the vertical direction Z of the cleaning device 10001 in the plane in which the rotary system is located, and the mounting angle position A2 of the support section 15 is the angle of the support section 15 relative to the vertical direction Z of the cleaning device 10001 in the plane in which the rotary system is located. The mounting angle position A1 of the second sludge scraper section 31 directs the mounting angle position A2 of the support section 15 in the first direction R.When the mop and wiper element 300 rotates in the first direction R, the second sludge scraper section 31 touches the mop and wiper element 300 before it reaches the support section 15, enabling the second sludge scraper section 31 to scrape the sludge from the mop and wiper element 300, so that at least part of the sludge has already been removed before the mop and wiper element 300 rotates into the area of ​​the support section 15.

[0080] Extended coverage area refers to the spatial area covered by a component from its starting point to its endpoint in a specific direction (here: the longitudinal direction X). If the extended coverage area D2 of the support section 15 is not within the extended coverage area D1 of the second sludge scraper section 31, the cleaning surface of the mop and wiper element 300, corresponding to the extended coverage area D2 of the support section 15, can come into contact with the support section 15 without being cleaned by the second sludge scraper section 31. This results in the mop and wiper element 300 not being cleaned in the axial direction of the rotation axis S of the mop and wiper element 300 within the extended coverage area D2 of the support section 15, or the cleaned wastewater not being able to directly enter the sludge collection chamber 111.If the extended coverage area D2 of the support section 15 is located within the extended coverage area D1 of the second sludge scraper section 31, during the rotation of the sludge scraper section 300 around the first direction R to clean the surface to be cleaned, the cleaning surface of the sludge scraper section 300, which reaches the support section 15, is cleaned by the second sludge scraper section 31, which facilitates the entry of the wastewater into the sludge receiving chamber 111 after cleaning.

[0081] In certain embodiments, such as in Fig. As shown in Figure 5, the extended coverage area D1 of the second sludge scraper section 31 is connected to or overlaps the extended coverage area D3 of the sludge collection chamber 111 in a direction parallel to the axial direction of the axis of rotation S of the mop and wiper element 300 (in longitudinal direction X).

[0082] In particular, "adjacent" means that the second sludge scraper section 31 and the sludge receiving chamber 111 are spatially connected without overlapping. The overlap refers to the spatial intersection of the extended cover area D1 of the second sludge scraper section 31 and the extended cover area D3 of the sludge receiving chamber 111, so that the wastewater scraped from the second sludge scraper section 31 can easily enter the sludge receiving chamber 111, thereby reducing the risk of wastewater backup or overflow.

[0083] In certain embodiments, as in Fig. 5 shown, at least a part of the second sludge scraper section 31 is arranged upstream of the first sludge scraper section 13 in the direction of rotation (in the first direction R) of the mop and wiper element 300.

[0084] In particular, when the mop and wiper element 300 rotates around the first direction R, a portion (which may be all or part) of the second sludge scraper section 31 rests against the mop and wiper element 300 in front of the first sludge scraper section 13. The second sludge scraper section 31 scrapes the sludge from the mop and wiper element 300 before the first sludge scraper section 13 scrapes it, thereby reducing the load on the first sludge scraper section 13.

[0085] In certain embodiments, such as in the Fig. 4 and Fig. As shown in Figure 5, the extended coverage area of ​​the first sludge scraper section 13 overlaps with the extended coverage area D3 of the sludge receiving chamber 111. In this way, the wastewater scraped by the first sludge scraper section 13 can flow directly into the sludge receiving chamber 111.

[0086] In certain embodiments, such as in Fig. As shown in Figure 4, when the recycling component 100 is installed on the cleaning device 10001, the second sludge scraper section 31 is located above the sludge intake chamber 111 in the vertical direction Z of the cleaning device 10001.

[0087] In particular, at least part of the sludge collection chamber 111 is located below the second sludge scraper section 31 in the vertical direction Z of the cleaning device 10001. That is, at least part of the sludge collection chamber 111 lies below the second sludge scraper section 31 in the vertical direction Z of the cleaning device 10001.After the second sludge scraper section 31 has removed the sludge from the cleaning surface of the mop and wiper element 300, the wastewater contained in the sludge flows by gravity into the lower sludge collection chamber 111 and is thus naturally drained away. This ensures that the wastewater can flow into the sludge collection chamber 111, preventing wastewater from accumulating around the second sludge scraper section 31, reducing the risk of wastewater overflow, preventing secondary contamination of the surface to be cleaned by wastewater, and reducing the likelihood of wastewater re-adhering to the mop and wiper element 300. It improves the efficiency of wastewater drainage from the second sludge scraper section 31.

[0088] In certain embodiments, such as in Fig. As shown in Figure 4, the recycling element 10 further comprises a filter section 19. The filter section 19 is provided with filter holes 191, which are connected to the outside and the sludge receiving chamber 111, to allow wastewater from the sludge to enter the sludge receiving chamber 111 and to prevent solids from the sludge from entering the sludge receiving chamber 111. In the vertical direction Z of the cleaning device 10001, the filter section 19 is located higher than the first sludge scraper section 13 and lower than the second sludge scraper section 31.

[0089] The filter section 19 is designed to separate the sludge generated by the mop and wiper element 300 during the cleaning process. Since the sludge on the floor contains not only wastewater but also solid waste, sludge adheres to the mop and wiper element 300 and forms sludge, or because the mop and wiper element 300 itself is wet, the sludge on the mop and wiper element 300 can mix into a mixture of solid waste and wastewater. The filter section 19 is provided with filter holes 191 that are connected to the outer surface and the sludge collection chamber 111. In one example, the filter section 19 is a filter screen, with the filter screen located between the sludge collection chamber 111 and the outer surface and provided with multiple filter holes 191. The size of the filter holes 191 can be adjusted as needed, as long as wastewater is allowed to pass through but larger solids are not.When the cleaning device 10001 wipes the surface to be cleaned, the sludge scraped by the first sludge scraper section 13 and the second sludge scraper section 31 contains wastewater and solids mixed with wastewater. The wastewater is able to flow through the filter section 19 into the sludge collection chamber 111 and be stored there to prevent it from re-adhering to the mop and wiper element 300. Solid contaminants are retained by the filter section 19 and remain between the cleaning surface of the mop and wiper element 300 and the sludge scraper section, thus preventing solid contaminants from entering the sludge collection chamber 111. During operation of the cleaning device 10001, for example, the mop and wiper element 300 rotates in the first direction R, i.e.,The mop and wiper element 300 rotates downwards relative to the first mud scraper section 13 and the second mud scraper section 31.

[0090] In the vertical direction Z of the cleaning device 10001, the filter section 19 is positioned higher than the first sludge scraper section 13, so that after the sludge has been scraped off by the first sludge scraper section 13, the wastewater can pass directly through the filter section 19 into the sludge collection chamber 111. Furthermore, in certain embodiments, a sludge collection chamber 111 can be provided above the filter section 19. In this way, when the cleaning device 10001 is flipped, the sludge collection chamber 111, which was originally located at the top, is in a lower position, allowing the wastewater that was originally in the lower sludge collection chamber 111 to flow into the upper sludge collection chamber 111, thus preventing overflow or environmental pollution.

[0091] In the vertical direction Z of the cleaning device 10001, the filter section 19 is positioned lower than the second sludge scraper section 31, so that the wastewater can flow away naturally by gravity, ensuring that the wastewater can flow smoothly into the sludge receiving chamber 111, reducing the likelihood of wastewater re-adhering to the mop and wiper element 300, and preventing secondary contamination of the surface to be cleaned by wastewater.

[0092] In certain embodiments, such as in Fig. As shown in Figure 7, the second sludge scraper section 31 comprises a first end 311 and a second end 313, which are opposite each other in the longitudinal direction X parallel to the main body section 11. The first end 311 of the second sludge scraper section 31 is closer to the sludge receiving chamber 111 than the second end 313, and at least the second end 313 of the second sludge scraper section 31 is provided with a notch 315 for receiving the mop and wiper element 300.

[0093] In particular, in the longitudinal direction X parallel to the main body section 11, the second end 313 of the second sludge scraper section 31 is located far away from the sludge receiving chamber 111, and the wastewater scraped from the second end 313 of the second sludge scraper section 31 has a long path to reach the sludge receiving chamber 111, so that the wastewater can easily overflow from the second end 313. The second end 313 is provided with a notch 315. When the mop and wiper element 300 is partially received in the notch 315, the wastewater scraped off by the second sludge scraper section 31 near the second end 313 can be drawn off by the part of the mop and wiper element 300 that is directly opposite the notch 315, thereby reducing the residence time of the wastewater at the second end 313 and preventing wastewater from overflowing at the second end 313.

[0094] In certain embodiments, such as in Fig. As shown in Figure 7, the notch 315 in the longitudinal direction X of the cleaning device 10001 borders the inner wall surface 331 of the end cap 33 of the housing 30, and the longitudinal direction X of the housing 30 runs parallel to the axis of rotation S of the mop and wiper element 300.

[0095] In particular, in some embodiments, the adjoining features include the following: The notch 315 and the inner wall surface 331 are located close to each other but do not touch in the longitudinal direction X, and the outer contour of the notch 315 and the outer contour of the inner wall surface 331 are located close to each other but do not intersect. By maintaining a certain distance between the notch 315 and the inner wall surface 331, the risk of wastewater overflowing from the inner wall surface 331 can be reduced.

[0096] In some other embodiments, such as in Fig. As shown in Figure 7, the notch 315 is in contact with the inner wall surface 331.

[0097] In particular, in the longitudinal direction X of the cleaning device 10001, the notch 315 is in contact with the inner wall surface 331, wherein the outer contour of the notch 315 touches the outer contour of the inner wall surface 331 and the wall surface forming the notch 315 is the inner wall surface 331. When the mop and wiper element 300 is inserted into the notch 315, it can approach or rest against the inner wall surface 331, thereby further reducing wastewater leakage and improving the integration and structural strength between the components.

[0098] In certain embodiments, such as in Fig. As shown in Figure 5, the width Q1 of the notch 315 in the longitudinal direction X of the housing 30 is between 2 mm and 8 mm, and the longitudinal direction X of the housing 30 runs parallel to the axis of rotation S of the mop and wiper element 300.

[0099] In particular, the width Q1 of the notch 315 can be 2 mm, 2.5 mm, 3 mm, 3.7 mm, 4 mm, 4.6 mm, 5 mm, 6 mm, 7 mm, or 8 mm. If the width Q1 of the notch 315 is less than 2 mm, the notch 315 is too small for the mop and wiper element 300, and the wastewater in the notch 315 can only be suctioned away with difficulty by the mop and wiper element 300. If the width Q1 of the notch 315 is greater than 8 mm, the notch 315 is too large, and in the direction parallel to the axis of rotation S of the mop and wiper element 300, the extended coverage area D1 of the second sludge scraper section 31 does not cover the extended coverage area D3 of the sludge collection chamber 111. The second sludge scraper section 31 has a limited cleaning area and a low cleaning effect.

[0100] The width Q1 of the notch 315 is in the range of 2 mm to 8 mm, which ensures that the notch 315 can accommodate the mop and wiper element 300 and that the wastewater scraped off by the second sludge scraper section 31 at the second end 313 is drawn off by the mop and wiper element 300 to prevent overflow at the second end 313 and also to ensure that the scraping area of ​​the second sludge scraper section 31 is sufficient and a good scraping effect is achieved.

[0101] In certain embodiments, such as in the Fig. 6 and Fig. As shown in Figure 7, the housing 30 comprises an inner surface 353 facing the mop and wiper element 300, and a second mud-wiping section 31 is arranged on the inner surface 353. The second mud-wiping section 31 comprises a first surface 317 and a second surface 319, wherein the second surface 319 is a surface facing away from the inner surface 353, and the first surface 317 is a surface capable of wiping mud from the mop and wiper element 300. The first surface 317 connects the second surface 319 to the inner surface 353, and at least one edge 318 of the first surface 317, facing away from the inner surface 353, abuts the mop and wiper element 300.

[0102] In particular, the mop and wiper element 300 is rotatably mounted on the side of the housing 30 facing the surface to be cleaned and is in contact with the inner surface 353. The rotation of the mop and wiper element 300 is in contact with the inner surface 353, and the inner surface 353 can limit the mop and wiper element 300, improve the stability of its rotation in the first direction R, and reduce the gap between the mop and wiper element 300 and the inner surface 353, thereby reducing the leakage or accumulation of wastewater during the cleaning process. The second sludge scraper section 31 comprises a first surface 317 and a second surface 319. The first surface 317 is the surface of the second sludge scraper section 31 that faces away from the support section 15 in the forward direction M of the mop and wiper element 300.The second surface 319 is the surface facing away from the inner surface 353.

[0103] In one embodiment, the second mud scraper section 31 can project from the inner surface 353 towards the mop and wiper element 300 and form a first surface 317 and a second surface 319.

[0104] The second surface 319 and the first surface 317 together form the edge 138. During the rotation of the mop and wiper element 300 in the direction R to clean the surface, the edge 138 contacts the mop and wiper element 300 and generates pressure during rotation, causing the sludge to be detached from the mop and wiper element 300. The detached sludge collects on the first surface 317, preventing it from reaching the support section 15 in the direction R. The second surface 319 is also in contact with the mop and wiper element 300, and the second surface 319 forms a gap 353 between the mop and wiper element 300 and the inner surface. This allows the detached sludge to collect on the first surface 317, preventing the mop and wiper element 300 from suctioning the sludge again.that the sludge flows in the direction of the first direction R to the support section 15 and the sludge can be collected in the longitudinal direction X to the cleaning surface of the mop and wiper element 300 near the sludge collection chamber 111.

[0105] In certain embodiments, such as in the Fig. 6 and Fig. As shown in Figure 7, the first surface 317 approaches the mud collection chamber 111 in the longitudinal direction X of the housing 30 and in the direction from the outside of the housing 30 to the inside of the housing 30 (hereinafter referred to as the inward direction X1) in the direction of rotation (first direction R) of the mop and wiper element 300, wherein the longitudinal direction X of the housing 30 runs parallel to the axis of rotation S of the mop and wiper element 300.

[0106] In particular, the longitudinal direction X of the housing 30 is a bidirectional direction, encompassing two opposing unidirectional directions: from the outside of the housing 30 to the inside of the housing 30 and from the inside of the housing 30 to the outside of the housing 30. In the direction from the outside of the housing 30 to the inside of the housing 30 (direction X1 inwards), the first surface 317 approaches the sludge collection chamber 111 ever closer to it in the direction of rotation of the mop and wiper element 300, such that the first surface 317 forms an inclined surface relative to the sludge collection chamber 111.

[0107] The component of the first surface 317 in direction R maintains the sludge-scraping effect of the first surface 317 on the sludge on the mop and wiper element 300. The surface inclined in the longitudinal direction X of the housing 30 directs the sludge into the sludge collection chamber 111. The sludge scraped off by the second sludge-scraping section 31 approaches the sludge collection chamber 111 from the inside in direction X1 and is directed there directly, thus preventing sludge accumulation on the first surface 317.

[0108] In certain embodiments, such as in the Fig. 6 and Fig. As shown in Figure 8, the first surface 317 is an axially inclined surface relative to the axis of rotation S of the mop and wiper element 300 in the longitudinal direction X of the housing 30 and in the direction from the outside of the housing 30 to the inside of the housing 30 (inward direction X1).

[0109] In particular, as in Fig. As shown in Figure 8(a), the first surface 317 is a continuous inclined surface and is inclined axially with respect to the axis of rotation S of the mop and wiper element 300. The angle of inclination can be, for example, 15°, 18°, 21°, 30°, 40°, or 60°, etc., and is not limited here. The first surface 317 is inclined axially with respect to the axis of rotation S of the mop and wiper element 300 so that the sludge scraped off the first surface 317 can flow along the first surface 317 into the sludge collection chamber 111, thereby achieving good flow guidance.

[0110] In certain embodiments, such as in the Fig. 6, Fig. 7 and Fig. As shown in Figure 8, the first surface 317 comprises several sequentially connected sub-surfaces, and in the longitudinal direction X of the housing 30 and in the direction from the outside of the housing 30 to the inside (inward direction X1) the inclinations of the sub-surfaces relative to the axis of rotation S increase in series.

[0111] Particularly in another example, as in Fig. As shown in Figure 7, the first surface 317 consists of several sub-surfaces, which may, for example, comprise 2, 3, or 4 sub-surfaces, etc., without being limited thereto. For example, the first surface 317 consists of two sub-surfaces, namely a first sub-surface 3171 and a second sub-surface 3172, which are sequentially connected. In the direction X1, the first sub-surface 3171 faces further away from the sludge collection chamber 111 than the second sub-surface 3172. The inclination of the first sub-surface 3171 relative to the axis of rotation S is less than the inclination of the second sub-surface 3172 relative to the axis of rotation S. In the longitudinal direction X1 of the housing 30, the size of the first sub-surface 3171 is larger than the size of the second sub-surface 3172.During the rotation of the mop and wiper element 300, the first partial surface 3171 and the second partial surface 3172 can scrape sludge from the mop and wiper element 300 at different angles and with different forces. Since the first partial surface 3171 has a shallower incline and a greater length, the first partial surface 3171 and the edge 318 between the first partial surface 3171 and the second partial surface 319 achieve a better scraping effect. The second partial surface 3172 has a steeper incline and a shorter length. With the same scraping performance, its steeper incline allows it to direct the scraped sludge more quickly and directly into the sludge collection chamber 111, thus preventing accumulation and spillage.

[0112] Therefore, the inclinations of the partial surfaces relative to the axis of rotation S increase in series, which helps the sludge to slide quickly into the sludge receiving chamber 111 after stripping and prevents the sludge from remaining on the first surface 317 and re-adhering, thereby improving the recycling efficiency of the recycling device 100.

[0113] In certain embodiments, such as in the Fig. 6 and Fig. As shown in Figure 8, the first surface 317 comprises several sub-surfaces, the several sub-surfaces being sequentially connected to one another. In the longitudinal direction X1 of the housing 30 and in the direction from the outside of the housing 30 to the inside (direction X1), at least the sub-surface closest to the outside of the housing 30 and the sub-surface closest to the center of the housing 30 are inclined axially with respect to the axis of rotation S of the mop and wiper element 300, wherein the inclination of the sub-surface closest to the outside of the housing 30 with respect to the axis of rotation S is less than the inclination of the sub-surface closest to the center of the housing 30 with respect to the axis of rotation S.

[0114] Particularly in another example, as in Fig. As shown in Figure 8(b), the first surface 317 consists of several sub-surfaces, which may comprise 2, 3, or 4 sub-surfaces, etc., without being limited thereto. For example, the first surface 317 consists of three sub-surfaces. From the outside inwards in the housing 30, these sub-surfaces are a third sub-surface 3173, a fourth sub-surface 3174, and a fifth sub-surface 3175, which are sequentially connected, wherein the inclination of the third sub-surface 3173 relative to the axis of rotation S is less than the inclination of the fifth sub-surface 3175, and the fourth sub-surface 3174 is parallel to the axis of rotation S.

[0115] In particular, the slope of the third partial surface 3173 near the outer surface of the housing 30 is less steep, and the edge-scraping action of the third partial surface 3173 and the edge between the third partial surface 3173 and the second surface 319 is better. The fourth partial surface 3174 can form a relatively smooth transition zone, allowing the sludge to gradually adapt to the subsequent flow process of the fifth partial surface 3175 after cleaning by the third partial surface 3173. However, the fifth partial surface 3175, which is closer to the center of the housing 30, has a steeper slope, allowing the sludge to be guided more effectively into the sludge intake chamber 111. This ensures that the sludge is quickly absorbed into the sludge intake chamber 111 and prevents sludge residue and re-adhesion to the first surface 317.

[0116] In certain embodiments, such as in the Fig. 4 and Fig. As shown in Figure 6, a sealing element 50 is provided between the support section 15 and the housing 30, wherein the sealing element 50 is designed to seal the gap between the support section 15 and the housing 30.

[0117] In particular, the sealing element 50 is designed to seal the gap between the support section 15 and the housing 30 to improve the watertightness of the recycling element 10. The sealing element 50 can be made of materials such as rubber, silicone, plastic, or synthetic fibers. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, and silicone rubber. One or more seals 50 may be present, and this disclosure contains no limitations. In one example, the sealing element 50 is molded separately and then placed onto the support section 15 or the housing 30; in another example, the sealing element 50 is applied to the support section 15 or the housing 30 in the form of injection molding or similar materials and encapsulated with it.When the cleaning device 10001 is in the state of wiping the surface to be cleaned, the housing 30 is located above the sludge scraper section, the sealing element 50 is located on the side of the support section 15 facing away from the surface to be cleaned, and at least part of the sealing element 50 is located in the vertical direction Z between the support section 15 and the housing 30. The sealing element 50 seals the gap between the support section 15 and the housing 30, thus preventing the wastewater scraped by the first sludge scraper section 13 and the second sludge scraper section 31 from overflowing from the gap between the support section 15 and the housing 30. This prevents wastewater from escaping upwards and improves the watertightness of the recycling assembly 10. Furthermore, the sealing element 50 is cost-effective and does not require any additional installation space.

[0118] In certain embodiments, such as in Fig. 4 and Fig. As shown in Figure 6, the support section 15 rests against the mop and wiper element 300. During the rotation of the mop and wiper element 300 in the first direction R to clean the surface, the support section 15 removes the sludge from the mop and wiper element 300, with the sludge collection chamber 111 being designed to collect the sludge.

[0119] In particular, when the support section 15 abuts the wiper part 300, the support section 15 can also perform a scraping function and scrape off the wastewater that is located downstream of the second sludge scraper section 31 in the first direction R, thereby creating a double scraping effect with the second sludge scraper section 31.

[0120] In certain embodiments, such as in Fig. As shown in Figure 9, the support section 15 comprises a first support surface 155 and a second support surface 157. The first support surface 155 is further away from the mop and wiper element 300 than the second support surface 157, and the second support surface 157 is connected to the first support surface 155, with at least one edge of the first support surface 155, which is connected to the second support surface 157, abutting the mop and wiper element 300 and forming a straight line.

[0121] More precisely: If the edges of the first support surface 155 and the second support surface 157 are straight, they can be perpendicular ( Fig. 9(a)), acute-angled ( Fig. 9(b)) or obtuse-angled ( Fig. 9(c) and Fig. 9(d)). The first support surface 155 can be parallel to the first direction R ( Fig. 9(a)) or not parallel ( Fig. 9(c)), and the second support surface 157 can be perpendicular to the surface to be cleaned ( Fig. 9(d)) or not perpendicular ( Fig. 9(c)). There are no restrictions here. If the edges are straight lines, they can generate a higher local pressure, which allows mud to be removed more effectively from the surface of the mop and wiper element 300. In one example, if the stretching direction of the second support surface 157 (along the height direction Z) remains unchanged, adjusting the inclination angle of the first support surface 155 reduces the edge scraping force that occurs at an acute angle between the first support surface 155 and the second support surface 157 (see Fig. 9(b)) forms the edge formed at a right angle between the first support surface 155 and the edge formed at a right angle between the second support surface 157 (see Fig. 9(a)) and an obtuse angle (see Fig. 9(d)) forms, which can be adjusted as required so that the edge has an angle that achieves a scraping effect but does not allow water to pass through.

[0122] In certain embodiments, such as in Fig. As shown in Figure 6, the support section 15 comprises a first support surface 155, a second support surface 157, and a first transition surface 159. The first support surface 155 is located further away from the mop and wiper element 300 than the second support surface 157. The first transition surface 159 connects the first support surface 155 with the second support surface 157, and the first transition surface 159 abuts the mop and wiper element 300, with the edge being an arc surface.

[0123] In particular, the pressure exerted on the mop and wiper element 300 by the curved surface is better distributed at the point of contact between the first transition surface 159 and the mop and wiper element 300 than with a straight edge. Since the second sludge removal section 31 has already pre-cleaned the mop and wiper element 300, the remaining amount of sludge is significantly reduced. At this point, the first transition surface 159 is designed as a curved surface, which has a certain scraping effect and can further remove the remaining sludge after the mop and wiper element 300 has scraped it off.Furthermore, the large contact area between the arc surface and the mop and wiper element 300 can reduce the local pressure on the mop and wiper element 300, which helps to reduce excessive wiping of the mop and wiper element 300 by the first transition surface 159 and to prevent wastewater from overflowing from the contact surface between the first transition surface 159 and the mop and wiper element 300 due to excessive wiping force, thereby reducing the risk of water leakage.

[0124] In certain embodiments, such as in Fig. As shown in Figure 10, the support section 15 comprises a first support surface 155 and a second support surface 157, wherein the second support surface 157 is connected to the first support surface 155 and, in the vertical direction Z of the cleaning device 10001, the first support surface 155 is higher than the second support surface 157. The end of the second support surface 157 facing away from the first support surface 155 is further away from the mop and wiper element 300 than the end connected to the first support surface 155, and the first support surface 155 is in contact with the mop and wiper element 300, wherein the edge of the first support surface 155 that is connected to the second support surface 157 is a straight line or an arc.

[0125] Especially in Fig. 10(a) The first support surface 155 is in contact with the surface of the mop and wiper element 300, thus preventing sludge from dripping onto the surface to be cleaned in the vertical direction Z. For example, the first support surface 155 is parallel to the plane formed by the axis of rotation S of the mop and wiper element 300 and the vertical direction Z of the cleaning device 10001, thereby increasing the contact area between the first support surface 155 and the surface of the mop and wiper element 300 and reducing the local pressure exerted by the first support surface 155 on the mop and wiper element 300. If the edge of the side of the first support surface 155 that connects with the second support surface 157 is a straight line, the edge can exert a high local pressure, pressing the mop and wiper element 300 against it and preventing sludge from dripping onto the surface to be cleaned.If the edge of the side of the first support surface 155, which is connected to the second support surface 157, is an arc surface, the local pressure on the mop and wiper element 300 can be reduced, which helps to reduce the excessive wiping of the mop and wiper element 300 by the first transition surface 159 and to prevent overflow of wastewater from the contact area between the first transition surface 159 and the mop and wiper element 300 due to excessive wiping force, thereby reducing the risk of water leakage.

[0126] In certain embodiments, such as in Fig. As shown in Figure 10, the support section 15 comprises a first support surface 155 and a second support surface 157. The second support surface 157 is connected to the first support surface 155. In the vertical direction Z of the cleaning device 10001, the first support surface 155 is higher than the second support surface 157. The end of the first support surface 155 facing away from the second support 157 is further away from the mop and wiper element 300 than the end where the first support surface 155 and the second support surface 157 are connected, and the second support surface 157 is in contact with the mop and wiper element 300, with the edge of the second support surface 157 that is connected to the first support surface 155 being a straight line or an arc.

[0127] Especially in Fig. 10(b) The second support surface 157 is in contact with the surface of the mop and wiper element 300, thus preventing sludge from dripping onto the surface to be cleaned in the vertical direction Z. For example, the second support surface 157 is parallel to the plane formed by the axis of rotation S of the mop and wiper element 300 and the vertical direction Z of the cleaning device 10001. If the edge of the second support surface 157, which is connected to the first support surface 155, is a straight line, the edge can exert a high local pressure, pressing the mop and wiper element 300 against it and preventing sludge from dripping onto the surface to be cleaned.If the edge of the side of the second support surface 157, which is connected to the first support surface 155, is an arc surface, the local pressure on the mop and wiper element 300 can be reduced, which helps to reduce excessive wiping of the mop and wiper element 300 by the first transition surface 159 and to prevent overflow of wastewater from the contact area between the first transition surface 159 and the mop and wiper element 300 due to excessive wiping force, thereby reducing the risk of water leakage.

[0128] It is noteworthy that the surface of the mop and wiper element 300 is an arcuate surface. When the second support surface 157 is in contact with the mop and wiper element 300, the arcuate surface of the mop and wiper element 300 gradually moves away from the support surface 157 due to its relatively low position as the mop and wiper element 300 moves downwards. This results in a relatively low contact pressure between the mop and wiper element 300 and the support surface 157. This reduces the wiping force on the mop and wiper element 300 and minimizes the risk of wastewater overflow due to excessive wiping force. Simultaneously, the lower contact pressure protects the surface of the mop and wiper element 300 and extends its service life. Furthermore, wear on the mop and wiper element 300 and the risk of water leakage are reduced, while still ensuring effective cleaning.

[0129] In certain embodiments, such as in the Fig. 4 and Fig. As shown in Figure 11, the recycling assembly 10 further comprises a filter section 19, wherein the filter section 19 is provided with filter holes 191 and the filter holes 191 are connected to the outside and the sludge receiving chamber 111 to allow wastewater from the sludge to enter the sludge receiving chamber 111 while simultaneously preventing solids from the sludge from entering the sludge receiving chamber 111. The first sludge scraper section 13 comprises a first surface 131 and a second surface 133, wherein the first surface 131 is the inner surface of the filter holes 191, and at least one edge of the first surface 131, which is connected to the second surface 133, abuts the mop and wiper element 300, the edge being a straight line.

[0130] In particular, in Fig. 11(a) the first surface 131 of the first sludge scraper section 13 the upper surface of the sludge scraper section, the sludge scraped from the clean surface of the mop and wiper element 300 by the first sludge scraper section 13 collects on the first surface 131 of the first sludge scraper section 13, and the wastewater contained in the sludge flows from the top into the filter holes 191. In some embodiments, the first sludge scraper section 13 and the filter section 19 form a single-piece structure, which on the one hand leads to a more compact design between the first sludge scraper section 13 and the filter section 19, thus facilitating timely scraping of the wastewater into the sludge receiving chamber 111, and on the other hand ensures a smoother and gap-free connection between the first sludge scraper section 13 and the filter section 19, thereby minimizing the accumulation of sludge.In some embodiments, if the filter holes 191 are rectangular in shape, the top of the first sludge scraper section 13 can form one side of the rectangular shape to increase the efficiency of the wastewater flow.

[0131] In certain embodiments, the first surface 131 of the first sludge scraper section 13 is inclined downwards towards the sludge collection chamber 111. The first surface 131 of the first sludge scraper section 13 forms a downward angle on the side facing the sludge collection chamber 111. This inclination is due to the fact that the first surface 131 of the first sludge scraper section 13 is not horizontally oriented and has a certain height difference in the vertical direction Z.The first surface 131 of the first sludge scraper section 13 is inclined downwards, which exerts a certain steering effect on the wastewater, and the wastewater slides more easily through the first surface 131 into the sludge receiving chamber 111 under the influence of gravity, thereby increasing the velocity at which the wastewater enters the sludge receiving chamber 111 through the filter opening 191, thus improving the efficiency of the recycling element 10 in wastewater treatment. The angle between the first surface 131 of the first sludge scraper section 13 and the surface to be cleaned can be 5°–30°, etc., and is not limited in this disclosure.

[0132] At least one edge of the first surface 131, which is connected to the second surface 133, rests against the mop and wiper element 300. If the edge is a straight line, it generates a high local pressure that quickly scrapes the sludge from the adjacent mop and wiper element 300. After filtration through the filter section 19, the wastewater contained in the sludge flows quickly into the sludge collection chamber 111, thereby improving the cleaning performance of the mop and wiper element 300.

[0133] In certain embodiments, such as in the Fig. 4 and Fig. As shown in Figure 11, the recycling assembly 10 further comprises a filter section 19, wherein the filter section 19 is provided with filter holes 191 and the filter holes 191 are connected to the outside and the sludge receiving chamber 111 to allow wastewater from the sludge to enter the sludge receiving chamber 111 while simultaneously preventing solids from the sludge from entering the sludge receiving chamber 111. The first sludge scraper section 13 comprises a first surface 131, a second surface 133, and a second transition surface 135, wherein the first surface 131 is the inner surface of the filter holes 191, the second transition surface 135 connects the first surface 131 and the second surface 133, and at least one edge of the first surface 131 connected to the second surface 133 rests against the mop and wiper element 300, the edge being an arcuate surface.

[0134] In particular, it connects Fig. 11(b) the second transition surface 135 the first surface 131 and the second surface 133, creating a smooth transition zone which helps to reduce the accumulation of sludge between the first surface 131 and the second surface 133 and ensures that the sludge can pass unhindered from the first surface 131 through the filter holes 191 into the sludge collection chamber 111. The smooth second transition surface 135 can also reduce the friction between the mop and wiper element 300 and the first sludge scraper section 13 during rotation, thereby extending the service life of the mop and wiper element 300 and the first sludge scraper section 13 and reducing maintenance costs.

[0135] The curved edges reduce local pressure on the mop and wiper element 300, preventing excessive wear or damage to the mop and wiper element 300 caused by excessive local pressure. They also help reduce excessive wiping of the mop and wiper element 300 by the first transition surface 159 and prevent wastewater from overflowing from the contact area between the first transition surface 159 and the mop and wiper element 300 due to excessive wiping force, thus reducing the risk of water leakage. The curved edges also reduce wastewater overflow caused by excessive wiping force.Since the pressure distribution at the edge is more uniform in the form of an arc, the sludge is compressed less during wiping, thereby reducing the likelihood of wastewater overflow from the contact area, reducing the risk of leaks and improving the tightness and reliability of the cleaning device 10001.

[0136] In some embodiments, such as in Fig. 6 or Fig. As shown in Figure 9, the support section 15 does not extend beyond the first sludge scraper section 13 in the direction from the front section to the rear section of the cleaning device 10001, wherein the front section is the part of the cleaning device 10001 that points forward in the forward direction M, and the rear section is the part of the cleaning device 10001 that points backward in the forward direction M.

[0137] In particular, in the forward direction M, the front section of the cleaning device 10001 is the front part and the rear section is the rear part. By arranging the support section 15 behind the first sludge scraper section 13 and by ensuring that it does not extend beyond the first sludge scraper section 13, it can be ensured that the mop and wiper element 300 comes into contact with the first sludge scraper section 13 during the cleaning process and that the first sludge scraper section 13 can remove most of the dirt from the mop and wiper element 300.

[0138] In certain embodiments, the support section 15 is flush with the first sludge scraper section 13 in the direction from the front section to the rear section of the cleaning device 10001, so that the support section 15 and the first sludge scraper section 13 can scrape dirt from the mop and wiper element 300, thereby improving the scraping effect on the mop and wiper element 300.

[0139] In some embodiments, the first sludge scraper section 13 projects out of the support section 15 in the direction from the front section to the rear section of the cleaning device 10001, thereby reducing the friction between the support section 15 and the mop and wiper element 300, so that the support section 15 does not have a scraping function on the mop and wiper element 300 or its scraping ability is reduced and water escapes from the cleaning device.

[0140] The support section 15 is located in the rear section, thereby reducing wear and energy losses due to excessive friction between the support section 15 and the mop and wiper element 300, thus improving the service life and work efficiency of the cleaning device 10001.

[0141] In certain embodiments, such as in Fig. As shown in Figure 6, the second mud scraper section 31 is a single piece and is located either on the left or right side of the housing 30 in longitudinal direction X.

[0142] In particular, in some embodiments, the number of second sludge scraper sections 31 can be determined according to the configuration of the support section 15. For example, if the cleaning device 10001 is provided with only one drain pipe or one first wastewater outlet 181, then only one support section 15 and one second sludge scraper section 31 need to be provided.

[0143] In certain embodiments, such as in Fig. As shown in Figure 5, the second support section 31 comprises two parts, and the two second support sections 31 are arranged longitudinally X of the housing 30 on the left and right sides. The two second sludge scraper sections 31 are arranged symmetrically to the centerline of the length of the housing 30.

[0144] If the cleaning device 10001 is to be provided with a drain pipe and a first wastewater outlet 181, two support sections 15 and two secondary sludge scraper sections 31 must be installed at both ends of the dirt collection chamber 111. In other embodiments, the number of secondary sludge scraper sections 31 and the number of support sections 15 may not be the same. The two secondary sludge scraper sections 31 are arranged symmetrically to the centerline of the length of the housing 30. This ensures that the force on the mop and wiper element 300 is more uniform during rotation, thereby avoiding unnecessary vibrations or displacement of the device during operation due to an uneven distribution of components.

[0145] In certain embodiments, such as in Fig. As shown in Figure 5, the housing 30 comprises a housing main body 35 and an end cap 33, wherein the end cap 33 is located on the left and right sides of the housing main body 35 in longitudinal direction X and the longitudinal direction X of the housing main body 35 is parallel to the axis of rotation S of the mop and wiper element 300, wherein in longitudinal direction X of the housing main body 35 an end of the second lubrication element 31 borders the end cap 33; and / or wherein an end of the support section 15 borders the end cap 33.

[0146] In particular, the end cap 33 is designed to enclose a receiving space with the main housing body 35, wherein the recycling element 10 and the mop and wiper element 300 are both located in the receiving space.

[0147] For example, the end caps 33 comprise two end caps 33 located on the left and right sides of the main housing body 35 in the longitudinal direction X. The end cap 33 can restrict the left and right movement of the mop and wiper element 300 in the longitudinal direction X, thus ensuring the stability of the mop and wiper element 300 during rotation in the first direction R. In some embodiments, the end cap 33 and the main housing body 35 form an integral structure, i.e., the end cap 33 and the main housing body 35 form an integral structure, thereby improving the bond strength between the end cap 33 and the main housing body 35 and preventing the end cap 33 and the main housing body 35 from separating during operation of the recycling assembly 10, thus ensuring the stability and reliability of the operation of the recycling assembly 10.In other embodiments, the end cap 33 and the main housing body 35 are separate structures; that is, the end cap 33 and the main housing body 35 are two distinct structures. In one example, the end cap 33 and the main housing body 35 can be connected to each other by a detachable connection method, such as a snap-fit ​​or threaded connection. In another example, the end cap 33 and the main housing body 35 can be connected to each other by a non-detachable connection method, such as an adhesive bond or a welded connection. In this case, the two end caps 33 and the main housing body 35 of the present disclosure are formed in one piece, which further increases the structural strength of the housing 30, prevents deformation of the recycling element 10 under the force of the mop and wiper element 300, and prevents water from escaping from the recycling assembly 100.

[0148] If one end of the second sludge scraper section 31 abuts the end cap 33, the position of the second sludge scraper section 31 in the longitudinal direction X of the main housing body 35 can be restricted to ensure that it remains stable during the cleaning process, thereby improving the scraping action. This also optimizes the space utilization of the housing 30, resulting in a tighter fit between the second sludge scraper section 31 and the end cap 33 and reducing internal space loss. Adjacent positioning comprises two embodiments: contact and non-contact. When the second sludge scraper section 31 abuts the end cap 33, there is no gap between them, which further increases the stability of the structure and prevents the second sludge scraper section 31 from shifting during the cleaning process due to vibrations or external forces.Furthermore, the design can reduce the leakage of wastewater between the second sludge scraper section 31 and the end cap 33. If the second sludge scraper section 31 is not in contact with the end cap 33, a gap is created between them, which can act as a buffer to prevent damage to the second sludge scraper section 31 when external forces act on the end cap 33 and are transmitted to the second sludge scraper section 31.

[0149] When one end of the support section 15 abuts the end cap 33, the position of the support section 15 in the longitudinal direction X of the main housing body 35 can be restricted, ensuring that it remains stable during the cleaning process and thus improving the support effect. Furthermore, this optimizes the use of space inside the housing 30, resulting in a tighter fit between the support section 15 and the end cap 33 and less wasted space inside. Adjacent contact comprises two embodiments: contact and non-contact. When the support section 15 abuts the end cap 33, there is no gap between them, which further increases the stability of the structure and prevents the support section 15 from shifting during the cleaning process due to vibrations or external forces.If the support section 15 does not rest against the end cap 33, a certain gap is created between them, whereby this gap can serve as a buffer to prevent damage to the support section 15 when external forces act on the end cap 33 and when external forces are transmitted to the support section 15.

[0150] In certain embodiments, such as in Fig. As shown in Figure 6, during the cleaning process of the cleaning device 10001, with which the surface to be cleaned is cleaned, the longitudinal direction X of the main body section 11 is parallel to the axis of rotation S of the mop and wiper element 300.

[0151] In particular, the longitudinal direction X of the main body section 11 is the extension direction of the main body section 11. The axis of rotation S of the mop and wiper element 300 is the center line of rotation of the mop and wiper element 300 when it rotates about the first direction R. The longitudinal direction X of the main body section 11 runs parallel to the axis of rotation S of the mop and wiper element 300, which on the one hand optimizes the arrangement between the main body section 11 and the mop and wiper element 300, resulting in a more compact design, and on the other hand ensures that the interaction force between the mop and wiper element 300 and the main body section 11 is evenly distributed along the longitudinal direction X during rotation, thereby reducing asymmetrical forces and extending the service life of the main body section 11 and the mop and wiper element 300.

[0152] Similarly, in certain embodiments, the direction of extension of the dirt collection chamber 111 is aligned with the direction of the axis of rotation S, thereby making the structure of the dirt collection chamber 111 and the mop and wiper element 300 more compact. This also ensures a uniform distribution of the wastewater scraped off by the first sludge removal section 13 within the dirt collection chamber 111, thus preventing local accumulations of wastewater that could lead to blockages in the dirt collection chamber 111.

[0153] In certain embodiments, the direction of extension (longitudinal direction X) of the first dirt scraper section 13 runs parallel to the axis of rotation S. When the mop and wiper element 300 rotates about the axis of rotation S along the first direction R, the first dirt scraper section 13 contacts the clean surface of the mop and wiper element 300, generating a counterforce. The direction of extension of the first dirt scraper section 13 coincides with the direction of rotation S, so that the force of the first dirt scraper section 13 relative to the mop and wiper element 300 is distributed uniformly in the axial direction of rotation S. Therefore, the first scraper section 13 can scrape dirt uniformly from the clean surface of the mop and wiper element 300, thus ensuring consistent cleaning results.

[0154] As in Fig. As shown in Figure 3, the cleaning device 10001 in certain embodiments comprises a water spray bar 9000. The water spray bar 9000 is designed to spray the mop and wiper element 300 with cleaning fluid. After the mop and wiper element 300 has wiped the surface to be cleaned, the water spray bar 9000 sprays the mop and wiper element 300 with cleaning fluid, so that the dirt on the mop and wiper element 300 mixes with the cleaning fluid and forms dirt particles, wherein the second sludge scraper section 31 and the first sludge scraper section 13 scrape the dirt off one after the other, so that it enters the sludge collection chamber 111.

[0155] In particular, in the direction of travel M of the cleaning device 10001, the recycling element 10 is located behind the mop and wiper element 300, and the front of the mop and wiper element 300 is equipped with a water spray bar 9000. The water spray bar 9000 is able to spray cleaning fluid to moisten the mop and wiper element 300, and the mop and wiper element 300 is able to wipe the surface to be cleaned while wet and to pick up the dirt after wiping. During the rotation of the mop and wiper element 300 in the direction of R, the second sludge scraper section 31 is located upstream of the first sludge scraper section, whereby at least part of the sludge picked up by the mop and wiper element 300 from the surface to be cleaned is scraped off by the second sludge scraper section 31 before it enters the area of ​​the support section 15.The scraped-off sludge then flows into the sludge collection chamber 111. As the mop and wiper element 300 rotates further towards the first sludge scraping section 13, this scrapes off the remaining sludge, thus ensuring a clean surface of the mop and wiper element 300.

[0156] In the direction of travel M of the cleaning device 10001, the water spray bar 9000 is located at the front of the mop and wiper element 300 and the recycling element 10 at the rear of the mop and wiper element 300, whereby the area wetted by the cleaning surface of the mop and wiper element 300 is as far away as possible from the areas wiped by the first sludge scraper section 13 and the second sludge scraper section 31, which increases the contact time of the cleaning fluid on the cleaning surface of the wiper element 300, so that more dirt can be removed when wiping the mop and wiper element 300.

[0157] In certain embodiments, such as in Fig. As shown in Figure 4, the support section 15 is connected to the main body section 11.

[0158] In one example, the support section 15 is connected to other parts of the recycling element 10 (e.g., the main body section 11), provided that the support section 15 can support the first sludge scraper section 13, which is located at one or both ends of the dirt collection chamber 111. In some embodiments, the support section 15 and the main body section 11 form an integral structure, thereby improving the bond strength between the support section 15 and the main body section 11 and preventing them from separating during operation of the recycling element 10, thus ensuring the stability and reliability of the recycling element 10's operation. In other embodiments, the support section 15 and the main body section 11 are separate structures; that is, the support section 15 and the main body section 11 are two distinct structures.In one example, the support section 15 and the main body section 11 can be connected by a detachable connection method, such as a snap-fit ​​or threaded connection. In another example, the support section 15 and the main body section 11 can be connected by a permanent connection method, such as an adhesive bond or a weld.In the present disclosure, the main body section 11, the support section 15 and the first sludge scraper section 13 are formed in one piece, and in the embodiment in which the recycling element 10 further comprises a filter section 19, the filter section 19, the main body section 11, the support section 15 and the first sludge scraper section 13 are also formed in one piece, thereby further increasing the structural strength of the recycling element 10, preventing deformation of the recycling element 10 under the force of the mop and wiper element 300 and further preventing water from escaping the recycling assembly 100.

[0159] In certain embodiments, as in Fig. As shown in Figure 4, the support section 15 is attached to the housing 30 and is located in the longitudinal direction X on at least one side of the main body section 11. The support section 15 is connected to the housing 30.

[0160] In another example, the support section 15 is connected to the housing 30, meaning that the support section 15 can be mounted on the housing 30 as a structure independent of the recycling element 10. The connections of the housing 30 can be detachable or non-detachable, which improves the installation flexibility of the support section 15. Alternatively, the support section 15 can be part of the housing 30 and form a fixed unit with it, which can improve the strength of both the support section 15 and the housing 30.

[0161] In certain embodiments, such as in Fig. 3 and Fig. As shown in Figure 4, the support section 15 comprises a first support section 151 and a second support section 153. The first support section 151 is arranged on one side of the main body section 11 in the longitudinal direction X, and the second support section 153 is arranged on the other side of the main body section 11 in the longitudinal direction X. The first support section 151 projects out of the sludge receiving chamber 111 to form a first escape space 171, the first escape space 171 being designed for the installation of other structures of the recycling element 10 or other structures of the cleaning device 10001. The second support section 153 projects out of the sludge receiving chamber 111 to form a second escape space 173, the second escape space 173 being designed for the installation of other structures of the recycling element 10 or the cleaning device 10001.

[0162] In particular, the sludge collection chamber 111 is provided at one end near the first bypass chamber 171 with a first wastewater outlet 181, and the sludge collection chamber 111 is provided with a second wastewater outlet 183 near the second bypass chamber 173. The first wastewater outlet 181 is located laterally on the sludge collection chamber 111 in the longitudinal direction X, and the second wastewater outlet 183 is located above the sludge collection chamber 111 in the vertical direction Z. When the surface to be cleaned is wiped by the cleaning device 10001, the wastewater scraped off by the first sludge scraper section 13, the second sludge scraper section 31, and the support section 15 is temporarily collected in the sludge collection chamber 111.

[0163] For example, the first clearance space 171 is designed for the installation of a wastewater pipe, the wastewater pipe connecting the sludge receiving chamber 111 to the cleaning base station 10003 for servicing the cleaning device 10001. The first support section 151 projects significantly from the recycling element 10. Thus, in the forward direction M, on the side of the support section 15 facing away from the mop and wiper element 300, a certain empty area is created, the empty area being the first clearance space 171. In a forming process, the first clearance space 171 can be machined by local cutting or forming, and its shape is generally a regular rectangular groove, but may also have an irregular groove depending on the arrangement of the cleaning device 10001. The first clearance space 171 is located at one end of the longitudinal direction X of the sludge receiving chamber 111.If it is necessary to discharge the wastewater from the sludge receiving chamber 111 to the cleaning base station 10003 or outside the cleaning system 10000 (e.g., via a floor drain in a domestic toilet), at least part of the wastewater pipe is installed in the first bypass space 171. The inlet end of the wastewater pipe is connected to the sludge receiving chamber 111, and the outlet end of the wastewater pipe is capable of discharging the wastewater from the sludge receiving chamber 111 outside the recycling element 10. The first bypass space 171 provides space for the installation of the wastewater pipe and allows its compact integration within the first bypass space 171 without affecting the functional arrangement of other components.

[0164] For example, the second auxiliary space 173 is designed to avoid interference with other structures of the cleaning device 10001. The second auxiliary space 173 is designed for the installation of the second wastewater outlet 183. The wastewater box 500 of the cleaning device 10001 is connected to the sludge collection chamber 111 via the second wastewater outlet 183. The mop and wiper element 300 can wipe the surface to be cleaned and simultaneously collect the wastewater generated during the wiping process in the wastewater box 500 via the second wastewater outlet 183, thus realizing the self-cleaning function of the mop and wiper element 300 in the cleaning device 10001. The position and height, shape, and size of the second wastewater outlet 183 can be freely determined, and this disclosure does not impose any restrictions.For example, the second wastewater outlet 183 of the present disclosure is located above the sludge receiving chamber 111 in the vertical direction Z, thereby fully utilizing the volume of the sludge receiving chamber 111 for the temporary storage of wastewater.

[0165] In certain embodiments, such as in Fig. As shown in Figure 5, in the direction parallel to the axial direction of the rotation axis S of the mop and wiper element 300, the length L1 of the second mud scraper section 31 and the length L2 of the support section 15 satisfy the following condition: L1 = 0.8L2 ~ 1.8L2.

[0166] In particular, the length L1 of the second sludge scraper section 31 and the length L2 of the support section 15 must meet the following conditions: L1=0.8L2, L1=0.88L2, L1=0.9L2, L1=1.1L2, L1=1.2L2, L1=1.3L2, L1=1.4L2, L1=1.5L2, L1=1.6L2, or L1=1.8L2. If L1 is less than 0.8L2, the coverage of the second sludge scraper section 31 is insufficient to work in conjunction with the support section 15 and complete the scraping process. This results in the wastewater not being scraped in time in some areas, thereby increasing the risk of water leakage at the support section 15. If L1 is greater than 1.8L2, the second sludge scraper section 31 may, due to excessive expansion, impair the normal operation of the first sludge scraper section 13 and thus reduce the overall cleaning effect.At L1=0.8L2~1.8L2, the second sludge scraper section 31 can not only fully cover the scraper area required by the support section 15, but also work together with the first sludge scraper section 13 to ensure the scraper action of the recycling element 10 and reduce the risk of water leakage.

[0167] In certain embodiments, such as in Fig. As shown in Figure 5, in the direction parallel to the axial direction of the rotation axis S of the mop and wiper element 300, the length L1 of the second sludge scraper section 31 and the length L3 of the sludge intake chamber 111 satisfy the following condition: L1 = 0.05L3 ~ 0.3L3.

[0168] In particular, the length L1 of the second sludge scraper section 31 and the length L3 of the sludge receiving chamber 111 must meet the following conditions: L1 = 0.05L3, L1 = 0.08L3, L1 = 0.1L3, L1 = 0.11L3, L1 = 0.12L3, L1 = 0.15L3, L1 = 0.18L3, L1 = 0.22L3, L1 = 0.26L3, or L1 = 0.3L3. If L1 is less than 0.05L3, the length of the second sludge scraper section 31 may be too short and the inlet area of ​​the sludge receiving chamber 111 may not be effectively covered, thus hindering the smooth flow of wastewater into the sludge receiving chamber 111 and potentially leading to wastewater overflow during the cleaning process. If L1 is greater than 0.3L3, the second sludge scraper section 31 may protrude excessively into the sludge collection chamber 111, impairing the normal storage function of the sludge collection chamber 111 and even obstructing the wastewater flow.At L1 = 0.05L3 to 0.3L3, the second sludge scraper section 31 directs the wastewater into the sludge receiving chamber 111 without affecting the internal structure of the sludge receiving chamber 111.

[0169] In certain embodiments, such as in Fig. As shown in Figure 5, in the direction parallel to the axial direction of the rotation axis S of the mop and wiper element 300, the length L2 of the support section 15 and the length L3 of the sludge collection chamber 111 satisfy the following condition: L2 = 0.05L3 to 0.15L3.

[0170] In particular, the length L2 of the support section 15 and the length L3 of the sludge collection chamber 111 satisfy the following conditions: L2 = 0.05L3, L2 = 0.06L3, L2 = 0.07L3, L2 = 0.08L3, L2 = 0.09L3, L2 = 0.1L3, L2 = 0.12L3, L2 = 0.13L3, L2 = 0.14L3, or L2 = 0.15L3. If L2 is less than 0.05L3, the support section 15 is too short and does not provide sufficient space for the assembly of other components of the recycling element 10 or the cleaning device 10001, which impairs the interaction between the recycling assembly 100 and other structures of the cleaning device 10001. If L2 is greater than 0.15L3, the support section 15 may take up too much space in the sludge collection chamber 111, which reduces the volume of the sludge collection chamber 111 and impairs the ability of the sludge collection chamber 111 to receive wastewater.For L2 = 0.05L3 to 0.15L3, the support section 15 provides the necessary support for the second sludge scraper section 31 and at the same time ensures that the sludge intake chamber 111 offers sufficient space to accommodate wastewater, so that the proper functioning of the cleaning device 10001 is maintained.

[0171] For example, in a configuration in a direction parallel to the axial direction of the rotation axis S of the mop and wiper element 300, the length L1 of the second sludge scraper section is 31 31.5 mm, the length L2 of the support section is 15 22 mm and the length L3 of the sludge collection chamber is 111 225 mm.

It should be noted that general technical personnel in this field may make various modifications and improvements without departing from the basic idea of ​​the present disclosure, and that all of these fall within the scope of protection of the present disclosure.
