Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically to a cleaning device and cleaning equipment. Background Technology

[0002] Currently, commercially available cleaning equipment (such as floor scrubbers) generally uses a motor to drive a high-speed rotating roller brush to scrub the surface to be cleaned. These devices typically also include scrapers that engage with the roller brush. As the brush rotates, the scrapers remove water and dirt from the brush surface, achieving self-cleaning. However, traditional scrapers are mostly rigid blades fixed relative to the roller brush. During the self-cleaning process, some dirt remains on the scrapers, resulting in incomplete cleaning and affecting cleaning efficiency. Furthermore, when the roller brush reverses to clean the scrapers, the scrapers cause significant damage to the brush's abrasive fabric. Therefore, providing a cleaning device and equipment that improves the cleaning efficiency of roller brush self-cleaning and reduces roller brush wear is a pressing technical problem that needs to be solved in this field. Utility Model Content

[0003] In view of the above problems, this application provides a cleaning device and cleaning equipment to solve the technical problems of low self-cleaning efficiency of the roller brush and easy wear of the roller brush bristles in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is conceived as follows:

[0005] In a first aspect, this application provides a cleaning device, comprising: a device body; a roller brush, which is rotatably disposed on the device body; a water outlet assembly disposed on the device body for spraying water onto the roller brush, the water outlet assembly including a receiving groove; and a scraping assembly disposed below the water outlet assembly, comprising a main body plate, a connecting part, and an elastic member, wherein the connecting part is rotatably connected to the water outlet assembly or the device body, and the main body plate is divided into a first part and a second part with the rotation axis of the connecting part as the dividing line, the first part being in interference contact with the roller brush, and the elastic member being elastically abutting against the second part and the water outlet assembly to drive the second part away from the receiving groove.

[0006] The cleaning device has at least a first state and a second state; in the first state, the roller brush rotates in a first direction, the second part of the main body plate leaves the receiving groove, and there is a first interference fit between the main body plate and the roller brush; in the second state, the roller brush rotates in a second direction, the second part of the main body plate is received in the receiving groove, and there is a second interference fit between the main body plate and the roller brush; wherein the first interference fit is greater than the second interference fit.

[0007] The difference between the first interference and the second interference is less than or equal to 3.5 mm.

[0008] The main plate has a rotatable angle greater than 0° and less than or equal to 39°.

[0009] The depth of the receiving groove increases in the direction away from the roller brush, forming an inclined surface.

[0010] The cleaning device includes a baffle connected to the first part of the water outlet assembly facing the main body plate and extending in a direction parallel to the rotation axis. In the first state, the baffle presses against the main body plate.

[0011] The cleaning device includes a first sealing strip connected to the side of the baffle facing the main body plate and extending in a direction parallel to the rotation axis. The first sealing strip elastically presses against the main body plate.

[0012] The device body is provided with a second sealing strip located below the main plate, and the second sealing strip elastically presses against the main plate.

[0013] The adapter includes a connecting plate and a rotating shaft. The connecting plate is perpendicularly connected to both ends of the main plate along the direction of rotation axis and is located on the same side of the main plate. The connecting plate is rotatably connected to the water outlet component or device body through the rotating shaft.

[0014] The main body plate includes a detachably connected scraper and a comb; or, the main body plate includes a scraper with a comb structure, the comb structure being disposed on one side of the first part parallel to the axis of rotation.

[0015] Secondly, this application also provides a cleaning device, including the cleaning apparatus as described above.

[0016] Unlike existing technologies, the beneficial effects of the embodiments in this application are as follows: This application uses a roller brush to drive the main plate to rotate and adjust its tilt angle, which facilitates the roller brush to clean the dirt left on the surface of the main plate, thereby improving the cleaning efficiency of the roller brush self-cleaning. Furthermore, due to the presence of the receiving groove, the tilt angle of the main plate can be limited within a reasonable range, allowing it to effectively clean the roller brush. The presence of the elastic element allows the main plate to quickly return to its original position, compensating for insufficient kinetic energy provided by the roller brush. Simultaneously, when the roller brush reverses direction, the contact pressure between the roller brush and the main plate can be reduced, thereby reducing wear on the roller brush cloth. The cleaning device provided by this application improves the self-cleaning efficiency of the roller brush while reducing roller brush wear, thus extending the service life of the equipment.

[0028] Please see Figures 1 to 4 , Figure 1 This is a partial cross-sectional structural diagram of one embodiment of the cleaning device provided in this application in its first state; Figure 2 This is a partial cross-sectional structural diagram of one embodiment of the cleaning device provided in this application in a second state; Figure 3 This is a partial structural schematic diagram of one embodiment of the cleaning device provided in this application; Figure 4 This is a partially enlarged cross-sectional structural diagram of one embodiment of the cleaning device provided in this application.

[0029] This application provides a cleaning device, which includes: a device body 10; a roller brush 20, which is rotatably disposed on the device body 10; a water outlet assembly 30, which is disposed on the device body 10 and is used to spray water onto the roller brush 20, the water outlet assembly 30 including a receiving groove 31; and a scraping assembly 40, which is disposed below the water outlet assembly 30 and includes a main plate 41, a connecting part 42, and an elastic member 43. The connecting part 42 is rotatably connected to the water outlet assembly 30 or the device body 10. With the rotation axis of the connecting part 42 as the dividing line, the main plate 41 is divided into a first part 41a and a second part 41b. The first part 41a is in interference contact with the roller brush 20, and the elastic member 43 elastically abuts against the second part 41b and the water outlet assembly 30 to drive the second part 41b away from the receiving groove 31.

[0030] The main body 10 is mainly used to provide an installation area for the functional components in the cleaning device, integrate various components with different functions to form a cleaning device, and play a physical protection role.

[0031] The roller brush 20 is the core cleaning component of the cleaning device. It is mounted on the main body 10 and rotates at high speed to rub against the surface to be cleaned (e.g., the floor), removing stains and oil. The roller brush 20 can rotate in opposite directions (forward and reverse) to adapt to different working conditions. Forward rotation is mainly used for efficiently scraping away wastewater, while reverse rotation is mainly used to prevent hair entanglement and loosen the brush bristles. The surface of the roller brush 20 is covered with bristles to improve cleaning effectiveness. The bristles typically have a specific arrangement and angle of inclination. Wear on the bristles is generally less when the roller brush 20 rotates forward and relatively greater when it rotates reverse. To extend the working life of the roller brush 20, improve its cleaning efficiency, and reduce bacterial growth, the roller brush 20 needs to be cleaned regularly.

[0032] The water outlet assembly 30 is responsible for water delivery and includes at least a water outlet plate cover with spray holes and a water outlet plate with a liquid interface. The water outlet assembly 30 sprays water onto the roller brush 20. The water flow works in conjunction with the high-speed rotating roller brush 20 to break down stubborn stains and improve cleaning efficiency.

[0033] The scraping assembly 40 is used to clean hair entangled on the roller brush 20 and to scrape away dirt and wastewater contained in the roller brush 20, thereby achieving self-cleaning of the roller brush 20. The scraping assembly 40 includes a main body plate 41, a connecting part 42, and an elastic member 43. The main body plate 41 is the component used to clean the roller brush 20. The connecting part 42 is rotatably connected to the water outlet assembly 30 or the device body 10, allowing the main body plate 41 to rotate about the rotation axis of the connecting part 42, thereby adjusting the tilt angle of the main body plate 41 and changing the contact pressure between the main body plate 41 and the roller brush 20. The rotation axis of the connecting part 42 is parallel to the rotation axis of the roller brush 20. The connecting part 42 includes, but is not limited to, a hinge, a pin, or a flexible hinge structure. The elastic member 43 is used to assist in adjusting the tilt angle of the main body plate 41. The elastic member 43 includes, but is not limited to, a spring or an elastic washer. Depending on actual needs, one or more elastic members 43 may be provided. In one embodiment, two elastic members 43 are provided.

[0034] The specific working process of the scraping component 40 is as follows: The first part 41a of the main body plate 41 is in interference contact with the roller brush 20, which facilitates the scraping and water squeezing of the roller brush 20 by the main body plate 41, thereby improving the self-cleaning efficiency of the roller brush 20. Furthermore, due to the interference contact, when the roller brush 20 rotates, it can drive the main body plate 41 to rotate in the direction of the roller brush 20's rotation through friction. Specifically, with... Figure 1 and Figure 2 For example, to illustrate: Figure 1 As shown, when the roller brush 20 rotates counterclockwise (clockwise), at the position where the roller brush 20 is in interference contact with the main body plate 41, the rotation direction of the roller brush 20 is upward, which can drive the first part 41a of the main body plate 41 to rotate upward. At this time, the second part 41b of the main body plate 41 rotates downward and away from the receiving groove 31; Figure 2 As shown, when the roller brush 20 rotates clockwise (reverses), at the position where the roller brush 20 is in interference contact with the main body plate 41, the rotation direction of the roller brush 20 is downward, which can drive the first part 41a of the main body plate 41 to rotate downward, so that the roller brush 20 can sweep away the dirt left on the main body plate 41. At this time, the second part 41b of the main body plate 41 rotates upward, approaches the receiving groove 31, and is limited by the receiving groove 31, so that the rotation angle of the main body plate 41 is not too large, causing it to leave the position of contact with the roller brush 20.

[0035] At the same time, when the roller brush 20 switches from reverse rotation to forward rotation, the second part 41b of the main body plate 41 elastically abuts against the elastic element 43 and moves away from the receiving groove 31 under the elastic force of the elastic element 43, so as to assist the second part 41b of the main body plate 41 to return from the position close to the receiving groove 31 to the position away from the receiving groove 31, and the first part 41a of the main body plate 41 returns from the downward tilted position. The elastic element 43 helps the main body plate 41 to quickly reset and reduce the moisture residue in the roller brush 20 when the roller brush 20 is in the forward rotation working state.

[0036] In the above process, the main plate 41 of the scraping assembly 40 is a rotatable structure. Driven by the roller brush 20, its tilt angle can be adjusted by rotation, facilitating the cleaning of dirt remaining on the surface of the main plate 41 by the roller brush 20. This improves the self-cleaning efficiency of the roller brush. Furthermore, the presence of the receiving groove 31 limits the tilt angle of the main plate 41 to a reasonable range, allowing it to effectively clean the roller brush 20. Due to the presence of the elastic element 43, the main plate 41 can quickly return to its original position, compensating for insufficient kinetic energy provided by the roller brush 20. Simultaneously, changes in the tilt angle of the main plate 41 alter the contact pressure between the roller brush 20 and the main plate 41. When the roller brush 20 reverses direction, this contact pressure is reduced, thereby reducing wear on the roller brush 20's fabric. The cleaning device provided in this application improves the self-cleaning efficiency of the roller brush 20 while reducing wear, thus extending the equipment's service life.

[0037] In one embodiment, the cleaning device has at least a first state and a second state; in the first state, the roller brush 20 rotates in a first direction, the second portion 41b of the main body plate 41 leaves the receiving groove 31, and there is a first interference fit between the main body plate 41 and the roller brush 20; in the second state, the roller brush 20 rotates in a second direction, the second portion 41b of the main body plate 41 is received in the receiving groove 31, and there is a second interference fit between the main body plate 41 and the roller brush 20; wherein the first interference fit is greater than the second interference fit.

[0038] In this application, the interference fit is defined as the length of the overlapping portion between the main body plate 41 and the roller brush 20, reflecting the tightness between the main body plate 41 and the roller brush 20.

[0039] like Figure 1 As shown, the cleaning device is in the first state, with the first direction being counterclockwise. The roller brush 20 rotates counterclockwise, and the second part 41b of the main body plate 41 leaves the receiving groove 31 and is limited by the structure of the device body 10 located below the main body plate 41. At this time, the main body plate 41 is in a horizontal state, and there is a first interference fit between the main body plate 41 and the roller brush 20; Figure 2As shown, the cleaning device is in the second state, with the second direction being clockwise. The roller brush 20 rotates clockwise, and the second part 41b of the main body plate 41 is accommodated in the receiving groove 31 and limited by the receiving groove 31. At this time, the first part 41a of the main body plate 41 is lower than the second part 41b of the main body plate 41, and there is a second interference fit between the main body plate 41 and the roller brush 20. It can be seen that the first interference fit is greater than the second interference fit. In the first state, the roller brush 20 rotates forward, and there is a large interference fit between the main body plate 41 and the roller brush 20, which can improve the cleaning force of the main body plate 41 and help the main body plate 41 squeeze out the sewage in the roller brush 20 and scrape off the dirt on the surface of the roller brush 20. In the second state, the roller brush 20 rotates in reverse, and there is a small interference fit between the main body plate 41 and the roller brush 20, which helps to reduce the reverse pulling of the main body plate 41 on the bristles of the roller brush 20, thereby reducing the wear of the roller brush 20.

[0040] By setting the interference fit difference between the two states, the cleaning intensity can be automatically adjusted according to the cleaning needs of the roller brush 20. When the roller brush 20 requires strong cleaning, the larger interference fit in the first state ensures close contact between the roller brush 20 and the main body plate 41, improving cleaning efficiency; when the roller brush 20 requires gentle cleaning, the smaller interference fit in the second state reduces frictional resistance and reduces wear on the roller brush 20. Therefore, changing the rotation direction of the roller brush 20 can be combined with different interference fits between the roller brush 20 and the main body plate 41 to achieve multi-mode cleaning and improve the adaptability of the cleaning device.

[0041] In one embodiment, the difference between the first interference and the second interference is less than or equal to 3.5 mm. For example, the first interference is 5.5 mm, and the second interference is 2 mm to 4.5 mm, which can be 2 mm, 3 mm, 3.5 mm, 4.5 mm, etc. Then the difference between the first interference and the second interference is 3.5 mm, 2.5 mm, 2 mm, 1 mm, etc.

[0042] The difference between the first interference fit and the second interference fit is within the above range, which can meet the interference fit adjustment requirements between the main body plate 41 and the roller brush 20, reduce the wear of the main body plate 41 on the bristles of the roller brush 20, and at the same time, the first interference fit is larger, which is conducive to the main body plate 41 playing a better scraping and combing role on the roller brush 20, and improving cleaning efficiency.

[0043] In one embodiment, the second interference is greater than 0. A second interference greater than 0 means that the second interference can be as small as close to 0 but not equal to 0, in order to achieve the basic roller brush cleaning function.

[0044] In one embodiment, the interference fit between the main body plate 41 and the roller brush 20 is 2mm to 5.5mm. For example, it can be 2mm, 2.5mm, 3mm, 3.5mm, 4.5mm, 5.5mm, etc. Within this range, the main body plate 41 can better scrape and comb the roller brush 20, and the main body plate 41 will not generate excessive resistance to the rolling of the roller brush 20. It should be noted that, since the main body plate 41 is a rotatable structure, there is at least a first interference fit and a second interference fit between the main body plate 41 and the roller brush 20, and the first interference fit is greater than the second interference fit.

[0045] In one embodiment, the rotatable angle of the main body plate 41 is greater than 0° and less than or equal to 39°. For example, it can be 16°, 25°, 30°, 39°, etc.

[0046] When the cleaning device is in the first state, the rotation angle of the main plate 41 is defined as 0°. The rotatable angle of the main plate 41 is defined as the rotation angle of the main plate 41 in the second state. The rotatable angle of the main plate 41 is related to the interference fit between the main plate 41 and the roller brush 20. The larger the rotation angle, the smaller the interference fit between the main plate 41 and the roller brush 20. Therefore, by adjusting the rotatable angle range of the main plate 41 through the limiting structure (including the receiving groove 31, the device body 10, etc.), the difference between the first and second interference fits, as well as the magnitude of the first and second interference fits, can be adjusted. The specific relationship is related to the size and shape of the cleaning device and can be calculated according to the actual situation in the application.

[0047] In one embodiment, the depth of the receiving groove 31 increases in the direction away from the roller brush 20, forming an inclined surface.

[0048] At this time, the receiving groove 31 is an inclined groove, and the inclined surface is the bottom surface of the inclined groove. The inclined groove provides a receiving space for the second part 41b of the main body plate 41 that rotates upward. In contrast, the first part 41a rotates downward, which makes it easier for the roller brush 20 to remove the dirt remaining on the surface of the main body plate 41. When the inclined surface contacts the surface of the second part 41b, the main body plate 41 reaches its maximum stroke, which limits its rotation angle and prevents it from falling off the roller brush 20. This helps to improve the cleaning efficiency of the main body plate 41 on the roller brush 20 in this state.

[0049] Understandably, by designing the tilt angle of the inclined surface, the maximum rotation angle of the main body plate 41 can be controlled. In one embodiment, when the cleaning device is in its first state and the main body plate 41 remains horizontal, the tilt angle of the inclined surface is the maximum rotation angle of the main body plate 41.

[0050] In one embodiment, the cleaning device includes a baffle 50 connected to the side of the water outlet assembly 30 facing the first portion 41a of the main body plate 41 and extending in a direction parallel to the rotation axis. In a first state, the baffle 50 presses against the main body plate 41.

[0051] The baffle 50 is connected to the side of the water outlet assembly 30 facing the first part 41a of the main plate 41. The baffle 50 is located above the main plate 41 and presses against the main plate 41, which limits the upward rotation angle of the first part 41a of the main plate 41. At this time, the main plate 41 is maintained in a position with a large interference between itself and the roller brush 20, and it is not easy for it to tilt upward.

[0052] While the baffle 50 limits the first part 41a of the main body plate 41, the structure of the device body 10 located below the scraping assembly 40 also limits the second part 41b of the main body plate 41, which helps to improve the positional stability of the main body plate 41.

[0053] In one embodiment, the length of the baffle 50 in the direction parallel to the rotation axis is equal to the length of the main plate 41, which can better exert the limiting function of the baffle 50 and at the same time provide a basis for the setting of the sealing structure.

[0054] In one embodiment, the cleaning device includes: a first sealing strip 60 connected to the side of the baffle 50 facing the main body plate 41 and extending in a direction parallel to the rotation axis, the first sealing strip 60 elastically pressing against the main body plate 41.

[0055] The first sealing strip 60 is made of a material with good elasticity and flexibility, capable of elastic deformation under external force and restoring its shape after the force is removed. The first sealing strip 60 elastically presses against the main body plate 41, meaning it remains pressed against the main body plate 41 throughout its entire rotational stroke. This seals the gap between the main body plate 41 and the baffle 50, reducing the possibility of dirt entering the cleaning device through this gap, thus helping to maintain the normal operating condition of the cleaning device and extending its service life. The length of the first sealing strip 60 in the direction parallel to the rotation axis is greater than or equal to the length of the main body plate 41 to achieve a good sealing effect. The material of the first sealing strip 60 includes, but is not limited to, rubber, silicone, etc., as long as it meets the above sealing requirements.

[0056] Furthermore, during the rotation of the main body plate 41, the first sealing strip 60 has a cleaning effect on the surface of the main body plate 41. For example, as the external force applied by the main body plate 41 to the first sealing strip 60 gradually increases, the first sealing strip 60 is squeezed towards the roller brush 20, which is equivalent to a scraping action, thereby scraping away the dirt remaining on the surface of the main body plate 41.

[0057] In one embodiment, the thickness of the first sealing strip 60 gradually decreases from the position near the baffle 50 to the position near the main body plate 41. The thickness of the first sealing strip 60 refers to the horizontal width of its cross-section perpendicular to the axis of rotation. The thickness of the first sealing strip 60 is thicker near the baffle 50, which helps to improve the stability of the connection between the first sealing strip 60 and the baffle 50; the thickness is thinner near the main body plate 41, which helps to ensure close contact between the first sealing strip 60 and the main body plate 41.

[0058] In one embodiment, a second sealing strip 70 is provided on the device body 10 below the main body plate 41, and the second sealing strip 70 elastically presses against the main body plate 41.

[0059] The second sealing strip 70 is also made of a material with good elasticity and flexibility, capable of elastic deformation under external force and recovering its shape after the force is removed. The second sealing strip 70 elastically presses against the main body plate 41, meaning it remains pressed against the main body plate 41 throughout its entire rotational stroke. This seals the gap between the main body plate 41 and the device body 10, reducing the possibility of dirt entering the cleaning device through this gap, thus helping to maintain the normal operating condition of the cleaning device and extending its service life. The length of the second sealing strip 70 in the direction parallel to the rotation axis is greater than or equal to the length of the main body plate 41 to achieve a good sealing effect. The material of the second sealing strip 70 includes, but is not limited to, rubber, silicone, etc., as long as it meets the above sealing requirements.

[0060] In one embodiment, the thickness of the second sealing strip 70 gradually decreases from the position near the device body 10 to the position near the main body plate 41. The thickness of the second sealing strip 70 refers to the horizontal width of its cross-section perpendicular to the axis of rotation. The second sealing strip 70 is thicker near the device body 10, which helps to improve the stability of the connection between the second sealing strip 70 and the device body 10; and it is thinner near the main body plate 41, which helps to ensure close contact between the second sealing strip 70 and the main body plate 41.

[0061] The first sealing strip 60 and the second sealing strip 70 work together to seal the gap caused by the rotatable function of the main plate 41. This is an adaptive design based on the scraping component 40, which is beneficial to maintaining the normal operating condition of the cleaning device.

[0062] like Figure 3 As shown, in one embodiment, the adapter 42 of the scraping assembly 40 includes a connecting plate 421 and a rotating shaft 422. The connecting plate 421 is vertically connected to both ends of the main body plate 41 along the direction of rotation axis and is located on the same side of the main body plate 41. The connecting plate 421 is rotatably connected to the water outlet assembly 30 or the device body 10 through the rotating shaft 422.

[0063] Two rotating shafts 422 are provided at both ends of the main plate 41 along the rotation axis. Through the cooperation of the connecting plate 421 and the rotating shafts 422, the main plate 41 can rotate around the rotating shafts. It can be understood that the connecting plate 421, the water outlet component 30 or the device body 10 are provided with matching fixing holes so that the rotating shaft 422 passes through the fixing holes to connect the connecting plate 421 and the water outlet component 30 or the device body 10; and the rotating shaft 422 is fixedly connected to the connecting plate 421 and rotatably connected to the water outlet component 30 or the device body 10.

[0064] In other embodiments, the adapter 42 may also be a hinge structure or an elastic hinge structure, as long as it allows the main body plate 41 to rotate.

[0065] In one embodiment, the main body plate 41 includes a scraper member 411 and a comb member 412 that are detachably connected; or, the main body plate 41 includes a scraper with a comb structure, the comb structure being disposed on one side of the first part 41a parallel to the axis of rotation.

[0066] Figure 3 The main body plate 41 shown includes a scraper 411 and a comb 412. The scraper 411 has a flange structure facing the comb 412 and is snap-fitted to the comb 412, thus achieving a detachable connection between the two. The scraper 411 is mainly used for squeezing out water, while the comb 412 is mainly used for removing hair and fluffing the bristles. Together, they improve the cleaning effect of the main body plate 41 on the roller brush.

[0067] The main body plate 41 can also be an integral structure, namely a scraper with a comb-like structure, which not only has a good cleaning effect but also facilitates the installation of cleaning devices.

[0068] This application also provides a cleaning device. The cleaning device includes the cleaning apparatus in any of the above embodiments. The cleaning device includes, but is not limited to, floor scrubbers, window cleaning machines, etc.

[0069] In this embodiment, the specific structure of the cleaning device is the same as that in the above embodiments. Since the cleaning device adopts all the technical solutions of all the embodiments of the above cleaning device, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0070] The present application will be described below through a specific embodiment. It should be understood that the embodiments described herein are only used to clearly illustrate the core innovative points of the present application and are not intended to limit the scope of protection of the present application.

[0071] When the cleaning equipment is in normal use, the roller brush rotates 20 degrees clockwise (forward). Figure 1The roller brush 20 drives the first part 41a of the main body plate 41 to flip upward. However, under the limit of the baffle 50 and the spring force, the main body plate 41 is in a horizontal position. There is a large interference between the roller brush 20 and the main body plate 41, which can achieve cleaning of the roller brush 20.

[0072] When the cleaning device is placed on the charging base for self-cleaning, the roller brush 20 rotates counterclockwise (reverses). Figure 2 The roller brush 20 drives the first part 41a of the main body plate 41 to flip downwards. When the flip angle is 16°, it is limited by the receiving groove 31 of the device body 10 and the water outlet structure. At this time, the interference fit of the main body plate 41 relative to the roller brush 20 decreases by 1mm. At the same time, the dirt on the main body plate 41 will fall off or be exposed on its surface, and cleaning is achieved under the action of the roller brush 20. The first sealing strip 60 and the second sealing strip 70 are in constant contact with the main body plate 41 during its rotation, and always seal it, reducing the possibility of dirt entering the cleaning equipment through gaps and causing the main body plate 41 to jam. At the same time, the reduction of the interference fit between the main body plate 41 and the roller brush 20 during rotation can effectively reduce damage to the roller brush 20 and improve its service life.

[0073] During normal use or self-cleaning, the cleaning equipment can also make the roller brush 20 rotate alternately in the forward and reverse directions, thereby improving the cleaning effect of the main plate 41 on the roller brush 20. When rotating in the reverse direction, the interference between the main plate 41 and the roller brush 20 is reduced, which can effectively reduce the damage to the roller brush 20.

[0074] This application provides a cleaning device, which includes: a device body; a roller brush that is rotatably disposed on the device body; a water outlet assembly disposed on the device body for spraying water onto the roller brush, the water outlet assembly including a receiving groove; and a scraping assembly disposed below the water outlet assembly, including a main plate, a connecting part, and an elastic member. The connecting part is rotatably connected to the water outlet assembly or the device body. With the rotation axis of the connecting part as the dividing line, the main plate is divided into a first part and a second part. The first part is in interference contact with the roller brush, and the elastic member elastically abuts against the second part and the water outlet assembly to drive the second part away from the receiving groove. This application utilizes a roller brush to rotate the main plate, adjusting its tilt angle to facilitate cleaning of dirt remaining on the main plate surface. This improves the self-cleaning efficiency of the roller brush. Furthermore, the presence of a receiving groove limits the tilt angle of the main plate to a reasonable range, ensuring its effective cleaning function. The elastic element allows the main plate to quickly return to its original position, compensating for insufficient kinetic energy provided by the roller brush. Simultaneously, the contact pressure between the roller brush and the main plate is reduced during reverse rotation, thus minimizing wear on the roller brush cloth. The cleaning device provided by this application improves the self-cleaning efficiency of the roller brush while reducing roller brush wear, extending the equipment's service life.

[0075] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
