Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning module and cleaning equipment. Background Technology

[0002] With the improvement of living standards, cleaning equipment is widely used. Cleaning equipment offers various methods for mopping surfaces, including rotary disc mopping, vibrating mopping, roller mopping, and belt mopping. Cleaning equipment features a self-cleaning characteristic of "living water cleaning," and the most important parameter affecting this ability is the wastewater recovery rate. The wastewater recovery rate is the ability to scrape wastewater off the cleaning components; the stronger this rate, the stronger the self-cleaning ability of the cleaning components, and consequently, the stronger the living water cleaning capability.

[0003] The existing wastewater recovery structure has a fixed amount of interference with the cleaning component, or the force between the wastewater recovery structure and the cleaning component is basically fixed. This results in a fixed ability of the wastewater recovery structure to scrape wastewater off the cleaning component, and the water content of the cleaning component cannot be adjusted according to actual needs. Utility Model Content

[0004] This application provides a cleaning module and cleaning equipment to solve the technical problems of existing scraping mechanisms being unable to adjust the scraping ability on the cleaning parts and the moisture content of the cleaning parts.

[0005] This application provides a cleaning module, which includes a cleaning bracket, a cleaning component, a scraping mechanism, and a drive mechanism. The cleaning component is rotatably mounted on the cleaning bracket and configured to interfere with the surface to be cleaned to clean the surface. The scraping mechanism is mounted on the cleaning bracket and at least partially interferes with the cleaning component to scrape off dirt from the cleaning component when the cleaning component moves. The drive mechanism drives the scraping mechanism to move relative to the cleaning bracket to actively adjust the amount of interference between the scraping mechanism and the cleaning component.

[0006] In an exemplary embodiment of this application, the drive mechanism includes a connecting shaft and a pressing member. The connecting shaft is configured to be mounted on a cleaning bracket and connected to a rotation drive unit; the pressing member is mounted on the connecting shaft, and the outer periphery of the pressing member has a plurality of pressing ends with smooth transitions between the pressing ends; wherein at least two pressing ends are at different distances from the axis of the connecting shaft, so that the scraping mechanism abutting against the pressing ends stops at at least two different positions; In an exemplary embodiment of this application, the driving mechanism includes a sensing structure. The sensing structure outputs a status signal when the pressing member rotates to a preset angle, so as to control the pressing member to stop at a preset position.

[0007] In an exemplary embodiment of this application, the sensing structure includes a marker and a sensor. The marker rotates synchronously with the pressing member; the sensor outputs a status signal in response to the marker rotating with the pressing member to a preset angle.

[0008] In an exemplary embodiment of this application, the smearing mechanism includes a smearing bracket rotatably mounted on a cleaning bracket. The smearing bracket has a smear collection chamber that collects dirt scraped off the cleaning component by the smearing mechanism. The top of the smear collection chamber has an opening. A scraper is mounted on the smearing bracket and is configured to interfere with the cleaning component to scrape off dirt on the cleaning component as it moves.

[0009] In an exemplary embodiment of this application, the bottom of the sludge scraper is provided with a removable cover, which covers the bottom of the sludge collection chamber. When the cover is removed, the bottom of the sludge collection chamber is open.

[0010] In an exemplary embodiment of this application, the cleaning bracket includes a rotating groove; the scraping bracket includes a rotating shaft, which is plugged into and detached from the rotating groove, and the rotating shaft is rotatable within the rotating groove.

[0011] In an exemplary embodiment of this application, the rotating shaft is plugged into the rotating slot along the length of the cleaning component.

[0012] In an exemplary embodiment of this application, the rotating groove includes multiple segments; the end of the rotating shaft is provided with a thickened portion, the cross-sectional diameter of which is larger than the cross-sectional diameter of the non-thickened portion of the rotating shaft.

[0013] A second aspect of this application provides a cleaning device, which includes a device body and a cleaning module as described above, wherein the cleaning module is installed on the device body.

[0014] In combination with existing technologies, the beneficial effects of this application are as follows: Existing scraping mechanisms cannot adjust their scraping ability on the cleaning components, nor can they adjust the moisture content of the cleaning components. The cleaning module of this application includes a scraping mechanism and a driving mechanism. The scraping mechanism at least partially interferes with the cleaning components to scrape off dirt from the cleaning components as they move. The driving mechanism drives the scraping mechanism to move relative to the cleaning support to actively adjust the amount of interference between the scraping mechanism and the cleaning components.

[0015] A larger interference amount can reduce the water content of the cleaning component, a medium interference amount can ensure that the cleaning component has a certain water content, and a lower interference amount allows the cleaning component to have more water. The interference amount of the cleaning component can be adjusted as needed to meet the usage requirements of different scenarios and improve the self-cleaning effect. Attached Figure Description

Detailed Implementation

[0019] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. The drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present application. However, it will be apparent to those skilled in the art that embodiments of the present application may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present application.

[0022] It should be noted that the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of this application. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered as part of the scope of this application.

[0023] This application provides a cleaning module and cleaning equipment. By adjusting the interference between the scraping mechanism and the cleaning component through the drive mechanism, the moisture content of the cleaning component can be adjusted to meet different usage scenarios and improve the self-cleaning effect.

[0024] The cleaning equipment described in this application can be a self-propelled cleaning robot or a handheld floor scrubber. The self-propelled cleaning robot can be a mopping robot or a combined sweeping and mopping robot, etc.

[0025] In the following embodiments, a self-moving cleaning robot is used as an example to describe some of its components. However, those skilled in the art will understand that the same beneficial effects brought by the cleaning module 10 or the scraping structure of this application can be achieved in other robots that include the cleaning module 10 or the scraping structure of this application.

[0026] The cleaning equipment has a main body, which can house various components. The main body can be any shape, such as cylindrical, elliptical, or D-shaped.

[0027] The cleaning equipment also includes a walking system conventionally found on existing cleaning equipment, used to drive the main body of the equipment to move independently across the surface to be cleaned. The walking system includes at least a driver and drive wheels, which rotate under the action of the driver. There are generally two drive wheels, symmetrically located at the bottom of the main body of the equipment. The specific structure of the walking system and the connection structure between the walking system and the main body of the equipment can be found in the relevant structural descriptions of existing cleaning equipment, and will not be repeated here.

[0028] To perform its cleaning function, the cleaning equipment includes at least a cleaning module 10. The cleaning module 10 is detachably connected to the main body of the equipment, and the detachable connection method can be a snap-fit ​​detachable connection, a bolt detachable connection, etc.

[0029] The cleaning module 10 is configured for wet mopping. The cleaning module 10 includes a cleaning component 200 and a cleaning bracket 100. The cleaning component 200 is mounted on the cleaning bracket 100. The cleaning component 200 includes, but is not limited to, a roller cleaning component 200 and a track cleaning component 200, to achieve wet cleaning.

[0030] In some embodiments, the cleaning device may further include side brushes and roller brushes, which are located at the bottom of the device body. Along the travel direction of the device body, both the side brushes and roller brushes are positioned in front of the cleaning module 10. The side brushes may be located at the edge of the device body and can rotate via a rotating mechanism, such as a motor, a combination of a motor and a reducer. When the side brushes rotate, they can gather debris from the edge of the device body towards the inside of the device body, thereby expanding the cleaning range of the cleaning device. The side brushes can be rubber strips or bristles, as long as they can clean the ground; there are no limitations. The roller brushes are rotatably disposed within a roller brush cavity at the bottom of the device body. During rotation, the roller brushes can sweep away debris on the ground. The number of roller brushes can be set according to specific requirements; this embodiment does not limit the number.

[0031] Along the direction of travel of the main body of the equipment, the side brush and roller brush are set in front of the cleaning module 10. This facilitates the cleaning operation of dry sweeping followed by wet mopping, and also facilitates the layout of the internal space of the main body of the equipment.

[0032] In addition to the above, the cleaning equipment may also include a sensing system and a control system. The sensing system and the control system are electrically connected. The sensing system includes an LDS located on top of the equipment body, a buffer and vision sensor located at the front of the equipment body, and an edge sensor located on the front side wall of the equipment body. Among them, the LDS, buffer, and edge sensor can all measure or sense distance to obtain the distance between the edge of the equipment body and obstacles. The control system uses this distance to control the cleaning equipment to perform corresponding actions. For example, controlling the cleaning equipment to perform obstacle avoidance, edge cleaning, and returning to the base station.

[0033] Please see Figures 1 to 23 This application provides a cleaning module 10, which includes a cleaning bracket 100, a cleaning component 200, a scraping mechanism 300, and a drive mechanism 500.

[0034] The cleaning bracket 100 provides a mounting carrier for some components of the cleaning component 200 and the cleaning module 10.

[0035] The cleaning component 200 is mounted on the cleaning bracket 100, and interferes with the surface to be cleaned to clean it. The cleaning component 200 can be a roller-type cleaning component 200, rotatably mounted on the cleaning bracket 100. The cleaning component 200 can also be a tracked cleaning component 200, with the tracked cleaning bracket 100 rolling relative to the surface to be cleaned to achieve cleaning. Of course, the cleaning component 200 can also be other wet cleaning components 200 suitable for use where the moisture content of the cleaning component 200 can be controlled by the scraping mechanism 300.

[0036] Please see Figure 2 and Figure 4 The scraping mechanism 300 is movably mounted on the cleaning bracket 100. The scraping mechanism 300 at least partially interferes with the cleaning component 200 to scrape off dirt from the cleaning component 200 as it moves. The dirt scraped by the scraping mechanism 300 includes sewage and other contaminants. The scraping mechanism 300 also scrapes off water from the cleaning component 200, thereby controlling the moisture content of the cleaning component 200. This prevents water stains from forming after mopping due to excessive moisture content in the cleaning component 200, and also prevents excessively low moisture content from affecting the mopping effect.

[0037] The drive mechanism 500 is mounted on the cleaning bracket 100. The drive mechanism 500 drives the scraping mechanism 300 to move relative to the cleaning bracket 100, so as to actively adjust the amount of interference between the scraping mechanism 300 and the cleaning component 200.

[0038] By adjusting the amount of interference between the scraping mechanism 300 and the cleaning component 200 through the drive mechanism 500, the moisture content of the cleaning component 200 can be adjusted to meet different usage scenarios and improve the self-cleaning effect.

[0039] Please see Figure 6 A larger amount of interference can reduce the moisture content of the cleaning component 200. For example, when the cleaning equipment detects a puddle of water on the ground, the moisture content of the cleaning component 200 is about to surge. In order to ensure the continuous water absorption effect through this area, the scraper 320 and the cleaning component 200 are adjusted to have a larger amount of interference. Or, when the cleaning equipment is self-cleaning at the base station, in order to ensure the self-cleaning effect and the low moisture content of the cleaning component 200 when leaving the base station, the scraper 320 and the cleaning component 200 are dynamically adjusted to a position with a larger amount of interference.

[0040] Please see Figure 5 The moderate interference ensures that the cleaning component 200 has a certain moisture content. For example, during normal mopping, the moisture content and cleaning ability are balanced, and the motor load of the cleaning component 200 is balanced.

[0041] Please see Figure 4A lower interference level ensures that the cleaning component 200 has a higher water content. For example, when the cleaning equipment is soaking the base station in water for self-cleaning, the water content of the cleaning component 200 needs to be increased, and the scraper 320 is dynamically adjusted to a position with a lower interference level. Alternatively, if the cleaning equipment detects an abnormally high motor current in the cleaning component 200 during cleaning, which may indicate that foreign objects are stuck or other issues, the scraper 320 is dynamically adjusted to a position with a lower interference level, thereby reducing the friction between the scraper 320 and the cleaning component 200 and reducing the motor load of the cleaning component 200.

[0042] Please see Figures 4 to 7 In some embodiments, the smear scraping mechanism 300 includes a smear scraping bracket 310 and a scraper 320.

[0043] The scraping bracket 310 serves two purposes: firstly, it mounts the scraping mechanism 300 onto the cleaning bracket 100; secondly, it provides a mounting structure for components such as the scraper 320. The scraping bracket 310 has a collection chamber 311, which collects the dirt scraped from the cleaning parts 200 by the scraping mechanism 300. The collection chamber 311 provides a temporary storage space for the dirt scraped from the cleaning parts 200 by the scraper 320. The dirt is collected in the collection chamber 311 of the scraping bracket 310, and the cleaning equipment only needs to extract the dirt from the collection chamber 311, making it convenient to transfer the dirt to the wastewater tank of the cleaning equipment.

[0044] The scraper 320 is mounted on the scraping bracket 310. The scraper 320 is used to interfere with the cleaning component 200 to scrape off the dirt on the cleaning component 200 when the cleaning component 200 moves. When the cleaning component 200 and the scraper 320 move relative to each other, the scraper 320 scrapes off the sewage and other dirt on the cleaning component 200, and the scraped sewage and other dirt collect in the dirt collection chamber 311.

[0045] The scraper 320 extends along the length of the cleaning component 200. For example, the length of the scraper 320 is the same as the length of the cleaning component 200, to scrape away sewage and other contaminants from the cleaning component 200. The length of the scraper 320 can be greater than the length of the cleaning component 200, and both ends of the scraper 320 extend beyond both ends of the cleaning component 200 to reduce the possibility of sewage flowing out along both ends of the scraper 320 after being scraped from the cleaning component 200, and to reduce the possibility of sewage flowing outside the collection chamber 311. Of course, in some embodiments, the length of the scraper 320 can also be slightly less than the length of the cleaning component 200. For example, when projected along the radial direction of the cleaning component 200, the distance between the projected end of the scraper 320 and the projected end of the cleaning component 200 is less than 1 cm, to facilitate the installation of the scraper 320 and reduce interference.

[0046] Please see Figure 9 In some embodiments, the scraper bracket 310 is provided with a slot 312 on the side near the cleaning component 200, and the scraper 320 is embedded in the slot 312.

[0047] The scraper 320 is fixed by embedding it into the slot 312, which eliminates the need for additional fasteners, facilitates assembly and production, and improves production efficiency.

[0048] For example, the scraper bracket 310 is a plastic scraper bracket 310. The plastic scraper bracket 310 has the advantages of easy processing, easy molding, light weight, and low cost. It can reduce the overall cost of the cleaning equipment, reduce the overall weight of the cleaning equipment, and improve the endurance.

[0049] The scraper 320 is a metal scraper 320. When the cleaning component 200 moves, it rubs against the scraper 320. By using the metal scraper 320, the wear of the scraper 320 can be reduced, the service life of the scraper 320 can be increased, and the scraping effect can be guaranteed.

[0050] The metal scraper 320 and the scraper bracket 310 are injection molded, which can improve the tightness and firmness of the connection between the scraper 320 and the scraper bracket 310, facilitate processing, reduce assembly steps, and improve production efficiency.

[0051] Of course, as some alternative methods, the scraper 320 and the scraper bracket 310 can also be fixed in other ways, such as by fasteners, snap-fit, adhesive bonding, etc.

[0052] Please see Figure 4 and Figure 9 In some embodiments, the slot 312 is inclined downwards from the direction closer to the cleaning component 200 to the direction farther away from the cleaning component 200. The force applied by the cleaning component 200 to the scraper 320 during the cleaning process causes the scraper 320 to tend to move downwards and away from the cleaning component 200. By tilting the scraper 320, the direction of the force exerted by the cleaning component 200 on the scraper 320 is consistent with or substantially consistent with the fixed direction of the scraper 320, reducing the risk of wobbling between the scraper 320 and the slot 312, ensuring the stability of the connection between the scraper 320 and the cleaning bracket 310, improving the service life of the cleaning mechanism 300, and reducing the risk of the scraper 320 falling off.

[0053] In some embodiments, a first engaging portion is provided in the slot 312, and a second engaging portion is provided on the scraper 320. The first engaging portion and the second engaging portion cooperate to restrict the movement of the scraper 320 and the slot 312 in the length direction of the scraper 320, so that the scraper 320 and the slot 312 remain in a limited position in the length direction of the scraper 320.

[0054] The first locking part can be a locking block, and the second locking part can be a groove. The relative fixation of the scraper 320 and the locking groove 312 is achieved through the cooperation of the locking block and the groove.

[0055] Of course, the first and second locking parts can also be other forms of limiting to prevent the scraper 320 from moving along the length of the scraper 320 in the slot 312.

[0056] In some embodiments, the interference point between the scraper 320 and the cleaning component 200 is a smooth curved surface, which ensures the scraping effect, reduces wear on the cleaning component 200, and improves the service life of the cleaning component 200.

[0057] For example, the interference point between the scraper 320 and the cleaning component 200 is rounded to ensure that the interference point between the scraper 320 and the cleaning component 200 is a smooth curved surface.

[0058] When the cleaning component 200 needs to self-clean or needs to be reversed under other circumstances, the friction between the cleaning component 200 and the scraper 320 will cause the scraper 320 to move closer to the cleaning component 200, which will result in a larger force between the cleaning component 200 and the scraper 320, and an increase in the motor load of the cleaning component 200.

[0059] Please see Figure 5 and Figure 8 In some embodiments, the direction of the interference point between the scraper 320 and the cleaning component 200 is directed toward the rotation axis 315 of the cleaning component 200, or substantially toward the rotation axis 315 of the cleaning component 200, thereby reducing the risk of the scraper 320 being driven by the cleaning component 200 and reducing the occurrence of the scraper 320 and the cleaning component 200 getting stuck or the cleaning component 200 motor being overloaded.

[0060] For example, if the cleaning component 200 is a roller-type cleaning component 200, then the direction of the interference point between the scraper 320 and the cleaning component 200 is the radial direction of the cleaning component 200, or substantially the radial direction.

[0061] For example, if the cleaning component 200 is a tracked cleaning component 200, then the direction of the interference point between the scraper 320 and the cleaning component 200 is the direction of the movement radius of the interference point of the cleaning component 200, or is basically close to the direction of the movement radius of the cleaning component 200.

[0062] Please see Figure 7 and Figure 9 In some embodiments, the scraper 320 protrudes from the scraper bracket 310, causing the scraper 320 to interfere with the cleaning component 200, while the scraper bracket 310 does not interfere with the cleaning component 200, thus avoiding wear on the scraper bracket 310 and reducing wear on the cleaning component 200.

[0063] Please see Figure 7 and Figure 9 In some embodiments, the scraping mechanism 300 includes a filter section 330, which is disposed on the dirt flow path between the scraper 320 and the dirt collection chamber 311 to filter dirt larger than a preset size.

[0064] The waste in the collection chamber 311 needs to be extracted into the wastewater tank of the cleaning equipment via the suction pipe 340. Occasionally, large pieces of dirt adhere to the cleaning component 200 when cleaning the surface. If these larger pieces of dirt are scraped off by the scraping mechanism 300 and then sucked up by the suction pipe 340, there is a risk of the suction pipe 340 becoming clogged, thus preventing further suction of dirt and wastewater. The scraping mechanism 300 of this application incorporates a filter section 330 along the dirt flow path between the scraper 320 and the collection chamber 311. Dirt larger than a preset size cannot pass through the filter section 330, thereby reducing the risk of clogging the suction pipe 340, minimizing manual cleaning intervention, and improving ease of use.

[0065] In some embodiments, the filter section 330 is disposed on the rear side of the scraper 320, and the bottom of the filter hole 331 of the filter section 330 is flush with or lower than the top of the scraper 320.

[0066] The bottom of the filter hole 331 can be flush with or lower than the top of the scraper 320. After the scraper 320 scrapes the sewage off the cleaning component 200, the sewage flows into the collection chamber 311 through the top surface of the scraper 320. The bottom of the filter hole 331 being flush with or lower than the top of the scraper 320 ensures that the sewage can flow into the collection chamber 311 through the filter hole 331, preventing the filter hole 331 from trapping sewage.

[0067] Please see Figure 8 In some embodiments, the filter section 330 is provided with extensions 313 at both ends. The extensions 313 extend towards the scraper 320 and extend beyond the scraper 320. In other words, the extensions 313 extend towards the cleaning member 200 to form a shield at both ends of the scraper 320, preventing the wastewater scraped by the scraper 320 from flowing towards both ends of the scraper 320. This allows the wastewater to flow along a preset route into the collection chamber 311, reducing the risk of secondary pollution of the surface to be cleaned due to the flow of wastewater to the surface to be cleaned.

[0068] Please see Figure 9 In some embodiments, a sludge collection trough 3111 is provided at the bottom of the sludge collection chamber 311.

[0069] The cleaning module 10 includes a suction pipe 340, the bottom of which is located at the collection trough 3111. The suction pipe 340 is mounted on the cleaning bracket 100. Of course, in some embodiments, the suction pipe 340 may also be mounted on the scraping bracket 310.

[0070] The suction pipe 340 is used to connect to the wastewater tank of the cleaning equipment, and the wastewater is sucked into the wastewater tank through the suction pipe 340. The collection trough 3111 extends downward from the collection chamber 311, and wastewater and other dirt will be collected in the collection trough 3111, which facilitates the collection of wastewater and other dirt, and makes it easy for the suction pipe 340 to suck the dirt in the collection chamber 311.

[0071] The bottom of the suction pipe 340 can extend into the collection tank 3111 to lower the liquid level in the collection tank 3111, reducing the amount of wastewater and other dirt left in the collection tank 3111 after cleaning and reducing the risk of dirt accumulation. The bottom of the suction pipe 340 can also be positioned above the collection tank 3111 to suck up wastewater above the collection tank 3111, reducing the risk of dirt accumulating in the collection tank 3111 and clogging the suction pipe 340.

[0072] In some embodiments, the bottom surface of the sludge collection chamber 311 is an inclined surface, and the sludge collection trough 3111 is located at the lower end of the inclined surface so that dirt flows into the sludge collection trough 3111.

[0073] When sewage enters the collection chamber 311, it flows along the inclined surface to the collection trough 3111 at the lower end of the inclined surface, preventing sewage from accumulating in other parts of the collection chamber 311 and facilitating the suction pipe 340 to suck up sewage and other dirt in the collection chamber 311.

[0074] The sludge collection trough 3111 can be located at one end of the bottom of the sludge collection chamber 311. The bottom wall of the sludge collection chamber 311 has a continuous inclined surface that slopes downward from the end away from the sludge collection trough 3111 to the end closer to the sludge collection trough 3111. Alternatively, the sludge collection trough 3111 can be located in the middle of the bottom of the sludge collection chamber 311. The bottom wall of the sludge collection chamber 311 has two inclined surfaces that slope downward from the end of the cover 360 toward the sludge collection trough 3111, so that sewage from both sides can flow into the sludge collection trough 3111, reducing the distance the sewage needs to flow and reducing the deposition of dirt on the top surface of the cover 360.

[0075] In some embodiments, a suction hole 341 is provided on the bottom periphery of the suction pipe 340.

[0076] When the suction pipe 340 is used to pump out sewage and other dirt, on the one hand, the suction hole 341 can reduce the amount of larger dirt entering the suction pipe 340, thus achieving a secondary filtration effect; on the other hand, when the bottom of the suction pipe 340 is blocked, the suction hole 341 on the side can continue to pump, ensuring the continuity of sewage pumping in the collection chamber 311, reducing the need for manual cleaning, and improving the convenience of use.

[0077] For example, a suction hole 341 extends through the end of the suction tube 340 to facilitate the suction of dirt from the end of the suction tube 340.

[0078] Please see Figure 11 and Figure 13 In some embodiments, the scraping mechanism 300 includes a cover 360, which is disposed at the bottom of the scraping bracket 310. The cover 360 is detachably connected to the scraping bracket 310 and covers the bottom of the sludge collection chamber 311. When the cover 360 is removed, the bottom of the sludge collection chamber 311 is open. In other words, part of the cover 360 serves as the bottom wall of the sludge collection chamber 311, and the bottom of the sludge collection chamber 311 is covered by the cover 360.

[0079] When the scraping structure is installed on the cleaning equipment and the cleaning equipment is in operation, the vertical direction is perpendicular to the surface to be cleaned, with the part closer to the surface to be cleaned being the bottom and the part farther away from the surface to be cleaned being the top. The bottom direction of the scraping bracket 310 refers to the side of the scraping bracket 310 closest to the surface to be cleaned when it is in operation.

[0080] A removable cover 360 is provided at the bottom of the scraper bracket 310. After removing the cover 360, the bottom of the sludge collection chamber 311 is open. On the one hand, dirt usually accumulates at the bottom of the sludge collection chamber 311, which is the upper part of the cover 360. Removing the cover 360 makes it easier to clean, improving cleaning convenience and reducing the risk of bacteria growth and odor caused by long-term dirt accumulation. On the other hand, the open bottom of the sludge collection chamber 311 facilitates cleaning inside the chamber, reducing dirt on the side walls and improving the cleanliness of the chamber, further reducing the risk of bacterial growth and odor.

[0081] Please see Figure 9 In some embodiments, the cover 360 includes a base plate 361 and a plug-in portion 362. The base plate 361 covers the bottom of the sludge collection chamber 311, and the plug-in portion 362 is plugged into and detached from the sludge collection chamber 311.

[0082] The plug-in part 362 is plugged into and unplugged into the sludge collection chamber 311, which facilitates the installation and removal of the cover plate, thereby facilitating the cleaning of the cover plate and the sludge collection chamber 311. The bottom of the sludge collection chamber 311 is sealed by the bottom plate 361 to prevent dirt and other contaminants from flowing out of the sludge collection chamber 311, thus ensuring the realization of the sludge collection function of the sludge collection chamber 311.

[0083] For example, the cover 360 can be a plastic or rubber part to ensure the connection stability between the cover 360 and the collection chamber 311.

[0084] Please see Figure 9 In some embodiments, a fixing groove 3621 is provided on the outer periphery of the insertion part 362, and a sealing ring 3622 is provided in the fixing groove 3621. The sealing ring 3622 is interference-fitted with the inner wall of the dirt collection cavity 311.

[0085] By using the interference fit between the sealing ring 3622 and the inner wall of the dirt collection chamber 311, on the one hand, the insertion and removal connection between the insertion part 362 and the dirt collection chamber 311 is ensured, making it convenient to disassemble and assemble the insertion part 362; on the other hand, the sealing ring 3622 can improve the sealing performance between the insertion part 362 and the dirt collection chamber 311, preventing sewage and other dirt from flowing out through the gap between the insertion part 362 and the side wall of the dirt collection chamber 311, reducing the risk of secondary pollution to the cleaned surface, and ensuring the cleaning effect.

[0086] For example, the fixing groove 3621 is continuously arranged around the outer circumference of the insertion part 362, and the sealing ring 3622 is a closed ring to ensure the overall sealing effect of the cover 360 and the sewage collection chamber 311, and reduce the risk of sewage flowing out of the sewage collection chamber 311.

[0087] Please see Figure 11 and Figure 13 In some embodiments, the end of the base plate 361 includes a handle 363, which at least partially protrudes from the scraper bracket 310.

[0088] The base plate 361 fits against the bottom of the scraper bracket 310, thereby ensuring that the base plate 361 covers the sludge collection chamber 311. By providing a handle 363 that protrudes at least partially from the scraper bracket 310, the user can easily remove the base plate 361 by applying force to the handle 363, thus improving the convenience of disassembly and assembly.

[0089] For example, the handle 363 protrudes from the side wall of the scraper bracket 310, and the portion of the handle 363 protruding from the side wall of the scraper bracket 310 is arc-shaped. The cover plate is located at the bottom of the scraper bracket 310. In some cases, the user will blindly remove the cover plate. The arc-shaped handle 363 can reduce the risk of bumps and knocks when the user blindly removes the cover plate, avoid injury to the user from sharp corners, and improve the safety of use.

[0090] In some embodiments, the scraping mechanism 300 includes a rotating shaft seat 314, and a rotating shaft 315 is provided in the rotating shaft seat 314. The rotating shaft 315 enables the scraping mechanism 300 to be rotatably connected to the cleaning bracket 100, so that the scraping mechanism 300 and the cleaning bracket 100 can rotate relative to each other.

[0091] In some embodiments, a plurality of support ribs are provided inside the sludge collection cavity 311. The support ribs connect the two sides of the sludge collection cavity 311, and the multiple support ribs are arranged along the length direction of the sludge collection cavity 311 to support it. Under the combined action of the force applied by the cleaning component 200 to the scraper 320 and the force applied by the drive mechanism 500 to the abutment portion 350, the sludge collection cavity 311 is prone to deformation and may be subject to deformation. By providing support ribs, the strength of the sludge collection cavity 311 can be improved, the deformation of the sludge collection cavity 311 can be reduced, the use of the sludge collection cavity 311 can be guaranteed, and the service life of the scraping mechanism 300 can be increased. Please see Figure 15 and Figure 16 In other embodiments, the scraping mechanism 300 includes a mounting part 315 for detachable connection with the cleaning bracket 100, allowing the scraping mechanism 300 to be detachably mounted on the cleaning bracket 100. When the sludge collection chamber 311 needs to be cleaned, the scraping mechanism 300 can be removed from the cleaning bracket 100, and the dirt in the sludge collection chamber 311 can be poured out through the opening 3112 at the top of the sludge collection chamber 311. At the same time, clean water can be injected into the sludge collection chamber 311 through the opening 3112, and a brush can be inserted to clean the sludge collection chamber 311. This effectively improves the problem of the existing sludge collection chamber 311 being inconvenient to clean and reduces the risk of dirt accumulation and bacterial growth in the sludge collection chamber 311.

[0092] For example, the mounting part 315 is detachably mounted to the cleaning bracket 100 along the length of the cleaning component 200.

[0093] The cleaning component 200 moves relative to the cleaning bracket 100 to clean the surface to be cleaned. The cleaning component 200 can rotate around its length or roll along the forward direction of the cleaning device. During this movement, the cleaning component 200 applies a force to the scraping mechanism 300, with the direction of the force perpendicular to the length of the cleaning component 200. The mounting part 315 is detachably connected to the cleaning bracket 100 along the length of the cleaning component 200, preventing the force applied by the cleaning component 200 to the scraping mechanism 300 from causing the mounting part 315 to detach from the cleaning bracket 100, thus improving the stability of the installation of the scraping mechanism 300 and the cleaning component 200.

[0094] The cleaning module 10 is located at the bottom of the cleaning equipment. Part of the cleaning module 10 is detached from the cleaning equipment along the length of the cleaning component 200, thus allowing the bottom side of the cleaning equipment to accommodate the detachment of the cleaning module 10. In some cleaning equipment, to reduce blind spots, the cleaning component 200 can move along its length to adjust the cleaning range and reduce blind spots, thus allowing the bottom side of the cleaning equipment to accommodate the movement of the cleaning module 10. For the above-mentioned and other cleaning equipment where the bottom side avoids the cleaning module 10, the movement of the mounting part 315 along the length of the cleaning component 200 does not require detaching the cleaning module 10; only the scraping mechanism 300 needs to be disassembled to clean the dirt collection chamber 311, facilitating cleaning and improving cleaning convenience.

[0095] Please see Figure 16 and Figure 18 For example, the mounting part 315 includes a rotating shaft 3151, the scraping bracket 310 rotates about the rotating shaft 3151 and the cleaning bracket 100, and the rotating shaft 3151 is detachably mounted to the cleaning bracket 100 along the length direction of the cleaning component 200.

[0096] The scraper bracket 310 and the cleaning bracket 100 are detached and connected at the rotating shaft 3151, eliminating the need for a separate rotating structure, simplifying component setup and reducing the failure rate.

[0097] The rotation of the scraping mechanism 300 and the cleaning bracket 100 can drive the scraper 320 and the cleaning component 200 to move relative to each other, thereby adjusting the amount of interference between the scraper 320 and the cleaning component 200 to meet the needs of different scenarios.

[0098] Please see Figure 18 In some embodiments, the scraping mechanism 300 includes an abutment portion 350 disposed on the scraping bracket 310. The abutment portion 350, the scraper 320 and the scraping bracket 310 form a lever to adjust the amount of interference between the scraper 320 and the cleaning component 200 when the abutment portion 350 drives the scraping bracket 310 to rotate.

[0099] In some embodiments, the abutment portion 350 is provided with reinforcing ribs. The reinforcing ribs can be provided on one side of the abutment portion 350, for example, on the side of the abutment portion 350 close to the drive mechanism 500, or on the side of the abutment portion 350 away from the drive mechanism 500. The reinforcing ribs can also be provided on both sides of the abutment portion 350, that is, the reinforcing ribs are respectively provided on the side of the abutment portion 350 close to the drive mechanism 500 and the side away from the drive mechanism 500, so as to improve the strength of the abutment portion 350, reduce the risk of deformation of the abutment portion 350 when subjected to the force of the drive mechanism 500, and improve the service life of the abutment portion 350.

[0100] The drive mechanism 500 abuts against the abutment part 350 to apply a force to the abutment part 350, causing the scraper 320 to interfere with the cleaning component 200. The drive mechanism 500 can adjust the amount of interference between the scraper 320 and the cleaning component 200 by controlling the position of the abutment part 350 to meet different usage requirements.

[0101] Please see Figure 16 In some embodiments, the rotating shaft 3151 is plugged into and connected to the cleaning bracket 100 along the rotating groove 110 of the cleaning bracket 100, and the rotating shaft 3151 is rotatable within the rotating groove 110.

[0102] The rotating shaft 3151 is plugged into the rotating groove 110, which facilitates the disassembly and assembly of the scraping mechanism 300 and improves the convenience of cleaning the dirt collection chamber 311.

[0103] Please see Figure 20 The abutment part 350 is provided with a relief part 351 at the rotating shaft 3151. The relief part 351 avoids the cleaning bracket 100 at the rotating groove 110, so that the rotating shaft 3151 can be inserted into or pulled out of the rotating groove 110.

[0104] The abutting part 350 is connected to the scraper bracket 310. The connection method includes, but is not limited to, fastener connection, snap connection, integral molding, etc. Preferably, the abutting part 350 and the scraper bracket 310 are integrally molded, which simplifies the processing steps and improves the assembly efficiency.

[0105] In some embodiments, the rotating groove 110 on the cleaning bracket 100 is provided with a notch that extends along the length of the cleaning component 200 and avoids the connection between the rotating shaft 3151 and the main body of the scraping bracket 310, so that the rotating shaft 3151 can be inserted into the rotating groove 110.

[0106] For example, a notch is provided on the lower side of the rotating groove 110 to prevent the rotating shaft 3151 from interfering with the scraper bracket 310 when it rotates in the rotating groove 110.

[0107] The central angle corresponding to the notch is less than 180°, which can prevent the rotating shaft 3151 from disengaging from the rotating groove 110 at the notch and ensure the connection stability between the scraping bracket 310 and the cleaning bracket 100.

[0108] Please see Figure 16 and Figure 18 In some embodiments, the end of the rotating shaft 3151 is provided with a thickened portion 3151, and the cross-sectional diameter of the thickened portion 3151 is larger than the cross-sectional diameter of the non-thickened portion 3151 of the rotating shaft 3151.

[0109] The cleaning bracket 100 is usually made of plastic, which has a certain degree of elasticity. By setting the thickened part 3151, the stability of the fit between the thickened part 3151 and the rotating groove 110 can be improved. The thickened part 3151 and the rotating groove 110 are interference fit. The force applied by the rotating groove 110 to the thickened part 3151 increases the friction between the thickened part 3151 and the rotating groove 110, reduces the risk of the thickened part 3151 disengaging from the rotating groove 110, and prevents the scraping bracket 310 from disengaging from the cleaning bracket 100.

[0110] In some embodiments, the rotating groove 110 comprises multiple segments, and these segments are independently arranged. This reduces the impact of the thickened portion 3151 on the rotating groove 110 and ensures the stability of the connection between the rotating groove 110 and the rotating shaft 3151. The multi-segment rotating groove 110 also facilitates machining, reduces the machining accuracy requirements of the rotating groove 110, and ensures the connection stability between the rotating groove 110 and the rotating shaft 3151.

[0111] For example, the drive mechanism 500 is disposed on the cleaning bracket 100, and the drive mechanism 500 drives the scraping mechanism 300 to move relative to the cleaning bracket 100, so as to actively adjust the amount of interference between the scraping mechanism 300 and the cleaning component 200.

[0112] Please see Figure 21In some embodiments, the drive mechanism 500 includes a connecting shaft 520 and a pressing member 530.

[0113] The connecting shaft 520 is mounted on the cleaning bracket 100 and connected to the rotation drive unit 510. The rotation drive unit 510 drives the connecting shaft 520 to rotate. The rotation drive unit 510 can be a drive motor, a combination of a drive motor and a speed change mechanism, or other types of rotation drive units that drive the connecting shaft 520 to rotate.

[0114] The connecting shaft 520 is rotatably mounted on the cleaning bracket 100. Various rotatable mounting methods are available. For example, the cleaning bracket 100 is equipped with a bearing, and the connecting shaft 520 is fixed to the inner ring of the bearing, allowing the connecting shaft 520 to be rotatably connected to the cleaning bracket 100 via the bearing. Alternatively, the connecting shaft 520 can be directly rotatably connected to the cleaning bracket 100, with a hole provided on the cleaning bracket 100. The connecting shaft 520 is installed in the hole and can rotate within it, thus achieving a rotatable connection between the connecting shaft 520 and the cleaning bracket 100. Of course, other rotatable connection methods are also possible between the connecting shaft 520 and the cleaning bracket 100.

[0115] Please see Figure 22 The pressing member 530 is mounted on the connecting shaft 520. The outer periphery of the pressing member 530 has multiple pressing ends 531, which are smoothly transitioned together. These pressing ends 531 are distributed around the outer periphery of the pressing member 530. When the pressing member 530 rotates to the abutment position, the pressing ends 531 abut against the scraping mechanism 300. The smooth transition between the pressing ends 531 makes the movement of the scraping mechanism 300 smoother and avoids sudden changes in force on the scraping mechanism 300.

[0116] At least two of the abutting ends 531 are at different axial distances from the connecting shaft 520, so that the scraping mechanism 300 mounted on the cleaning bracket 100, which abuts against the abutting ends 531, can remain in at least two different positions. The abutting position of the scraping mechanism 300 with the abutting end 531 is a fixed position or a position within a preset range. When different abutting ends 531 abut against the scraping mechanism 300, the distance between the different abutting ends 531 and the connecting shaft 520 is different, and the corresponding distance between the scraping mechanism 300 and the connecting shaft 520 is also different, thus allowing the scraping mechanism 300 to remain in different positions, which is beneficial for the scraping mechanism 300 to achieve its function.

[0117] Please see Figure 22 and Figure 23 In some embodiments, the pressing member 530 includes a first connecting hole 532 that extends through the pressing member 530 along its axial direction. The inner diameter of the first connecting hole 532 matches the outer diameter of the connecting shaft 520. The connecting shaft 520 extends through the first connecting hole 532, thereby connecting the connecting shaft 520 to the pressing member 530.

[0118] The pressing member 530 includes a second connecting hole 533, which extends radially through the pressing member 530 to the first connecting hole 532. The outer periphery of the connecting shaft 520 is provided with a positioning hole 521 radially along the connecting shaft 520. The second connecting hole 533 corresponds to the positioning hole 521, so as to connect the second connecting hole 533 and the positioning hole 521 through a connector.

[0119] By connecting the second connecting hole 533 and the positioning hole 521 with the connector, the positioning of the pressing member 530 on the connecting shaft 520 is realized, which is conducive to the rotation drive unit 510 driving the pressing member 530 to rotate to the preset position; the connector also realizes the relative fixation of the pressing member 530 and the connecting shaft 520.

[0120] In some embodiments, the first connecting hole 532 is interference-fitted with the connecting shaft 520, and the connecting member is a locating pin to connect the second connecting hole 533 and the locating hole 521. There is frictional resistance between the rotating pressing member 530 and the scraping mechanism 300. The connecting member limits the second connecting hole 533 and the locating hole 521, ensuring that the angle of the pressing member 530 on the connecting shaft 520 is stable during long-term use, thereby ensuring that the scraping mechanism 300 can accurately stop at the preset position.

[0121] In some embodiments, the connecting shaft 520 is inserted into the first connecting hole 532, and the connector is a fastener so that the second connecting hole 533 is connected to the positioning hole 521. For example, the connector is a screw, and the positioning hole 521 has an internal thread. The screw and the internal thread cooperate to achieve connection, thereby connecting the second connecting hole 533 to the positioning hole 521. The connector serves both the connecting and positioning functions.

[0122] Of course, as some alternatives, the pressing member 530 and the connecting shaft 520 can also be connected in other ways to fix the pressing member 530 to the connecting shaft 520.

[0123] Please see Figure 21 In an exemplary embodiment of this application, the rotation drive unit 510 is a drive motor, and the drive mechanism 500 includes a sensing structure 540. The sensing structure 540 outputs a status signal when the pressing member 530 rotates to a preset angle, so as to control the pressing member 530 to stop at a preset position.

[0124] When the pressing member 530 rotates to a preset angle, the sensing structure 540 outputs a status signal, which stops the drive motor and controls the pressing member 530 to stop at the preset position. The pressing end 531 abuts against the scraping mechanism 300, allowing the scraping mechanism 300 to remain at the preset position to perform its function. Controlling the stopping position of the pressing member 530 through the sensing structure 540 facilitates the function of the drive mechanism 500 in driving the scraping mechanism 300.

[0125] The sensing structure 540 can be an optocoupler sensing structure 540, a Hall sensor, an inductive angle sensor, an inertial measurement unit, or other sensing structures 540.

[0126] Please see Figure 21 In some embodiments, the sensing structure 540 includes an indicator 541 and a sensor 542. The indicator 541 rotates synchronously with the pressing member 530. The sensor 542 outputs a status signal in response to the indicator 541 rotating with the pressing member 530 to a preset angle.

[0127] The indicator 541 rotates synchronously with the pressing member 530. The sensing member 542 can sense the rotation angle of the pressing member 530 by sensing the rotation angle of the indicator 541, so that the sensing structure 540 can monitor the rotation angle of the pressing member 530.

[0128] For example, the sensor 542 is an optical coupler detection element, and the marking element 541 is a light shield so that light is reflected to the optical coupler detection element.

[0129] In some embodiments, the marker 541 includes at least one baffle and a blank space. The sensor 542 outputs a status signal in response to changes in the baffle and blank space at the sensing position.

[0130] The indicator 541 rotates with the pressing member 530, causing the sensing position to switch between a baffle and a blank position. The sensing member 542 can output a status signal in response to this switch, and control the rotation drive unit 510 based on the output status signal. For example, when the baffle is in position, the signal of the sensing member 542 is 1; when the blank position is in position, the signal of the sensing member 542 is 0. When switching from 0 to 1 or from 1 to 0, the sensing member 542 can output a status signal, and control the rotation of the rotation drive unit 510 based on the output status signal, so that the pressing member 530 can remain at a preset position.

[0131] For example, the marking element 541 includes a baffle and a blank. When the baffle is in place, the signal of the sensing element 542 is 1, and when the blank is in place, the signal of the sensing element 542 is 0. When the baffle is in place or the blank is in place, the initial position can be directly marked and the drive motor can be reset. When the baffle is switched to the blank and the blank is switched to the baffle, the drive motor needs to be turned off. This allows for two preset angle positioning, so that the pressing element 530 can stay at two preset angles. The scraping mechanism 300 can achieve two states.

[0132] The pressing member 530 may have two pressing ends 531, each with an usable angle of 90° to 170°, such as any value between 90° and 170°, including 90°, 100°, 150°, and 170°. The two pressing ends 531 have a smooth transition, and there is a certain misalignment between the baffle and the pressing ends 531. This misalignment is determined based on the rotational speed of the drive motor and the time from the output status signal of the sensor 542 to the stop of the drive motor, ensuring that the pressing member 530 can remain in a preset position when the sensor 542 outputs a status signal and the drive motor stops.

[0133] In some embodiments, the marker 541 includes at least three baffles arranged along the circumference of the marker 541, with a gap between adjacent baffles; wherein, the baffles include a large baffle and a plurality of small baffles, the central angle of the large baffle is larger than the central angle of the small baffles, and the sensor 542 outputs a status signal when it senses the gap at a preset position and switches to a baffle.

[0134] Under a constant rotational speed, the large baffle takes a relatively long time to pass the sensing position, allowing for the calibration or reset of the rotation angle of the pressing member 530. A status signal is output when switching from a blank position to a baffle; the number of blank and baffle switches corresponds to the number of pressing ends 531, facilitating control of the pressing ends 531. For example, the large baffle corresponds to the first pressing end 531; when the indicator 541 rotates to the first small baffle after the large baffle, it corresponds to the second pressing end 531, achieving a one-to-one correspondence between the pressing ends 531 and the baffles, thus facilitating control of the rotation angle of the pressing member 530.

[0135] For example, the indicator 541 has three baffles and three blanks. When the blanks switch to the baffles, a status signal can be output to control the motor to shut down, so that the pressing member 530 can stay in three preset positions, and the scraping mechanism 300 can stay in three positions.

[0136] The three baffles include a large baffle and two small baffles. The large baffle is used to calibrate the initial position, thereby calibrating the 530° rotation angle of the pressing part, which helps to ensure the accuracy of stopping the rotation.

[0137] The pressing member 530 has three pressing ends 531, each of which has an available angle of no more than 120°. Preferably, each pressing end 531 has an available angle of 60° to 110°, such as 60°, 90°, 110°, or any angle between 60° and 110°.

[0138] In some embodiments, the blank space includes a large blank space and multiple small blank spaces, the central angle of the large blank space is larger than the central angle of the small blank spaces, and the sensor 542 outputs a status signal when the baffle at the preset position switches to the blank space.

[0139] Under a constant rotational speed, the large blank space takes a relatively long time to pass the sensing position, allowing for the calibration or zeroing of the rotation angle of the pressing component 530. A status signal is output when the baffle switches to the blank space; the number of baffle switches and blank spaces corresponds to the number of pressing ends 531, facilitating control of the pressing ends 531. For example, the large blank space corresponds to the first pressing end 531; when the indicator 541 rotates to the first small blank space after the large blank space, it corresponds to the second pressing end 531, achieving a one-to-one correspondence between the pressing ends 531 and the blank spaces, thus facilitating control of the rotation angle of the pressing component 530.

[0140] For example, the indicator 541 has three baffles and three blanks. When the baffles switch to blanks, a status signal can be output to control the motor to shut down, so that the pressing member 530 can stay in three preset positions, and the scraping mechanism 300 can stay in three positions.

[0141] The three blanks include one large blank and two small blanks. The large blank is used to calibrate the initial position, thereby calibrating the 530° rotation angle of the pressing part, which helps to ensure the accuracy of stopping the rotation.

[0142] The pressing member 530 has three pressing ends 531, each of which has an available angle of no more than 120°. Preferably, each pressing end 531 has an available angle of 60° to 110°, such as 60°, 90°, 110°, or any angle between 60° and 110°.

[0143] In some embodiments, the label 541 is provided with a third connecting hole, which cooperates with the connecting shaft 520 so that the label 541 is mounted on the connecting shaft 520.

[0144] The third connecting hole cooperates with the connecting shaft 520 to fix the marking element 541 to the connecting shaft 520, thereby achieving relative fixation between the marking element 541 and the pressing element 530, and the marking element 541 and the pressing element 530 rotate synchronously.

[0145] The sensor 542 is mounted on the cleaning bracket 100. The connecting shaft 520 rotates with the connecting bracket, thereby driving the indicator 541 to rotate, so that the baffle and blank on the indicator 541 switch at the sensing position of the sensor 542.

[0146] Of course, as some alternatives, the drive mechanism 500 can also be other mechanisms that can drive the scraper bracket 310 to rotate relative to the cleaning bracket 100.

[0147] In some embodiments, the scraping mechanism 300 is slidably mounted on the cleaning bracket 100, and the driving mechanism 500 drives the scraping mechanism 300 to move relative to the cleaning bracket 100 to adjust the amount of interference between the scraper 320 and the cleaning component 200, so as to adjust the moisture content of the cleaning component 200 and meet different usage needs.

[0148] For example, the scraping mechanism 300 is slidably mounted on the cleaning bracket 100 in the form of a slider and a groove, including but not limited to a slider and a groove, and the driving mechanism 500 is a telescopic rod to drive the scraping mechanism 300 to move relative to the cleaning bracket 100.

[0149] Of course, as some alternatives, the drive mechanism 500 can also be other drive mechanisms 500 to drive the scraping mechanism 300 to move relative to the cleaning bracket 100.

[0150] A second aspect of this application provides a cleaning device, which includes a device body 20 and a cleaning module 10 as described above, wherein the cleaning module 10 is installed on the device body 20.

[0151] The cleaning equipment of this application is movably mounted on the cleaning bracket 100 via a scraping mechanism 300 and a drive mechanism 500 mounted on the cleaning bracket 100. The drive mechanism 500 drives the scraping mechanism 300 to move relative to the cleaning bracket 100, actively adjusting the amount of interference between the scraping mechanism 300 and the cleaning component 200 to meet different usage scenarios and improve the self-cleaning effect.

[0152] The cleaning equipment of this application also includes other structures, such as a walking mechanism, a control mechanism, and a clean water spraying mechanism. Please refer to existing cleaning equipment; this application will not elaborate on these.

[0153] The cleaning module 10 and cleaning equipment of this application adjust the amount of interference between the scraping mechanism 300 and the cleaning component 200 through the drive mechanism 500, thereby adjusting the moisture content of the cleaning component 200 to meet different usage scenarios and improve the self-cleaning effect.

[0154] Therefore, this application effectively overcomes some practical problems in the prior art and thus has high utilization value and significance.

[0155] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
