[0024] The cleaning device provided in this application embodiment uses a first power component to drive a pull cord to retract. The retraction of the pull cord causes the water channel support to rotate away from the roller brush. A reset component can then drive the water channel support to rotate closer to the roller brush after the pull cord is released. This allows the water channel support to operate at least in two different distances from the roller brush, enabling the cleaning device to function in various scenarios. For example, when the water channel support is relatively close to the roller brush, it is suitable for supplying cleaning fluid to the roller brush, allowing it to operate in a wetting mode; when the water channel support is relatively far from the roller brush, it is suitable for the roller brush to operate in a drying mode. This cleaning device is suitable for different cleaning needs, achieving multi-functionality and improving the user experience. Furthermore, the pull cord allows for flexible adjustment of the water channel support's position, while also allowing for flexible positioning of the first power component, facilitating the arrangement of the first drive assembly within the housing's accommodating cavity.

[0046] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0047] This application provides a cleaning device 100 for cleaning work surfaces (such as floors). The cleaning device 100 can be a handheld cleaning device or a self-propelled cleaning device.

[0048] Specifically, please refer to Figure 1 , Figure 2 and Figure 4 As shown, the cleaning device 100 includes a housing 1, a roller brush 2, a water channel support 3, a first drive assembly 4, and a reset component 8. The housing 1 is a generally enclosed structure. Figure 1 (Only a portion of the housing 1 is shown in the image). The housing 1 contains a cavity 10 for accommodating the water channel support 3, the first drive assembly 4, and the reset component 8, etc. The roller brush 2 rotates around a first axis (not shown). Figure 1 , Figure 2 and Figure 4 The roller brush 2 is shown rotating on the housing 1 along its axial direction (X). A portion of the roller brush 2 is located within the receiving cavity 10, while the other portion is exposed, allowing it to approach or even contact the ground. During its rotation, the roller brush 2 can wipe away or collect dirt, debris, and other foreign objects from the ground. The water channel support 3 is rotatably mounted within the receiving cavity 10 of the housing 1 around a second axis (not shown), with the first axis parallel to the second axis. The first drive assembly 4 is located within the receiving cavity 10 of the housing 1, as shown... Figure 2As shown, the first drive assembly 4 includes a first power component 41 and a pull rope 43. The two ends of the pull rope 43 are connected to the first power component 41 and the water channel support 3, respectively. The first power component 41 is used to retract the pull rope 43 in a direction away from the water distributor 31, and can also release the pull rope 43. When the first power component 41 drives the pull rope 43 to retract, the pull rope 43 can drive the water channel support 3 to rotate in a direction away from the roller brush 2 (please refer to [reference needed]). Figure 8 (As shown). Since the pull rope 43 is a flexible component, it cannot be tensioned on its own when released from the first power component 41. At this time, the reset component 8 located in the accommodating cavity 10 of the housing 1 provides a force to the water channel support 3 to rotate toward the roller brush 2, so that the water channel support 3 moves closer to the roller brush 2 (please refer to the reference). Figure 7 (As shown).

[0049] The cleaning device 100 provided in this application embodiment, through the cooperation of the first drive component 4 and the reset component 8, enables the water channel support 3 to operate in at least two states with different distances from the roller brush 2. Therefore, the cleaning device 100 can operate in different scenarios. For example, when the water channel support 3 is relatively close to the roller brush 2, it is suitable for supplying cleaning fluid to the roller brush 2, allowing the roller brush 2 to operate in a wetting mode. When the water channel support 3 is relatively far from the roller brush 2, it can be controlled to stop supplying water to the roller brush 2, allowing the roller brush 2 to operate in a drying mode. This cleaning device 100 can be adapted to different cleaning needs, satisfying multi-purpose functionality and improving the user experience. Furthermore, the pull rope 43 drives the water channel support 3 to rotate, and the position of the pull rope 43 can flexibly adapt to the position of the water channel support 3. Simultaneously, it allows for flexible positioning of the first power component 41, facilitating the arrangement of the first drive component 4 within the accommodating cavity 10 of the housing 1.

[0050] Both the first axis and the second axis are parallel to the working surface of the cleaning device 100. For example, when the cleaning device 100 is working on a horizontal working surface, the first axis and the second axis are horizontal lines that are parallel to each other.

[0051] In one embodiment, please refer to Figure 2 As shown, the first drive assembly 4 also includes a pull rope guide 44, which is rotatably or fixedly mounted on the inner surface of the housing 1. The pull rope 43 changes direction by sliding on the surface of the pull rope guide 44 or by driving the pull rope guide 44 to rotate. This further allows for flexible positioning of the first power component 41.

[0052] For further information, please refer to [link / reference]. Figure 2 As shown, in one embodiment, the first drive assembly 4 further includes a transmission member 42 connected to the output shaft of the first power member 41. This arrangement aims to allow the first power member 41 and the rope guide member 44 to be positioned in a more suitable manner and location through the transmission member 42. For example, Figure 2 As shown, the first power component 41 is a motor with a relatively large dimension along its output shaft. In this case, the motor is suitable for a generally horizontal arrangement, and the relative orientation between the motor and the pull rope 43 is matched through the transmission component 42. Furthermore, the transmission component 42 allows for a certain degree of deceleration of the pull rope 43, enabling more precise control over the retraction and release of the pull rope 43. This allows for more accurate control of the rotation of the water channel support 3, preventing the pull rope 43 from being over-tensioned or unable to be tensioned. Finally, the transmission component 42 allows the first power component 41 to be positioned as close as possible to the inner wall of the housing 1 along the axial direction X of the roller brush 2, while the pull rope 43 and the pull rope guide 44 can be positioned relatively close to the center of the roller brush 2. This facilitates a relatively balanced and distributed force distribution of the tension provided by the pull rope 43 across the water channel support 3, thereby ensuring smooth and balanced rotation of the water channel support 3.

[0053] The number of transmission components 42 can be one or more, forming a transmission group. There is no particular limitation here, as long as they can be adapted to the position of the motor output shaft and the pull rope guide 44. In some cases, one of the transmission components 42 can be configured to rotate and wind and release the pull rope 43 during rotation and reverse rotation.

[0054] The form of the reset component 8 is not limited. For example... Figure 2 , Figure 7 and Figure 8 As shown, the reset element 8 can be a linear, elastically compressible element such as a compression spring. In other alternative embodiments, the reset element 8 can be a torsion spring.

[0055] In one embodiment, please refer to [reference needed]. Figure 2 and Figure 3 As shown, the inner surface of the housing 1 is provided with a first limiting part 13 and a second limiting part 14. The first limiting part 13 is located on the side of the water channel support 3 facing the roller brush 2, and the second limiting part 14 is located on the side of the water channel support 3 away from the roller brush 2. The water channel support 3 rotates between the first limiting part 13 and the second limiting part 14.

[0056] The first limiting part 13 and the second limiting part 14 define two extreme positions for the water channel support 3, one close to and one far away from the roller brush 2. The purpose of this arrangement is that, with the use of the cleaning device 100, transmission errors may occur between the first power member 41, the transmission member 42, and the pull rope guide member 44, and the reset force provided by the reset member 8 may change (e.g., the elastic modulus of the spring decreases), causing changes in the tension of the pull rope 43. By limiting the first limiting part 13 and the second limiting part 14, the problem of the water channel support 3 getting too close to or even abutting against the pull rope guide member 44, and the problem of getting too close to the roller brush 2 and affecting the rotation of the roller brush 2, can be avoided. In turn, it helps the pull rope 43 maintain a proper tension during the retraction and release process.

[0057] The first limiting part 13 and the second limiting part 14 can be provided on at least one side of the inner surface of the housing 1 along the axial direction X of the roller brush 2. That is, the first limiting part 13 and the second limiting part 14 can abut against both ends of the water channel support 3 along the axial direction X of the roller brush 2. For details, please refer to Figure 2 and Figure 3 As shown, both the first limiting part 13 and the second limiting part 14 are limiting protrusions that protrude relative to the inner surface of the housing 1. In an optional embodiment, the first limiting part 13 and the second limiting part 14 can be disposed on the inner surfaces of the housing 1 on both sides along the axial direction X of the roller brush 2, thereby limiting both ends of the water channel support 3 along the axial direction X of the roller brush 2.

[0058] Please see Figure 7 As shown, when the water channel support 3 abuts against the first limiting part 13, the distance between the water channel support 3 and the roller brush 2 is at its minimum. This is the first operating mode of the cleaning device 100. Please refer to... Figure 8 As shown, when the water channel support 3 abuts against the second limiting part 14, the distance between the water channel support 3 and the roller brush 2 is at its maximum. At this time, it is the second working mode of the cleaning device 100.

[0059] In some embodiments, the cleaning device 100 may also have at least one third working mode between the first working mode and the second working mode, in which the water channel support 3 is spaced apart from both the first limiting part 13 and the second limiting part 14.

[0060] Please refer to the following: Figure 7 , Figure 8 and Figure 9As shown, in one embodiment, the water channel support 3 includes a water distributor 31 and a first scraper 33 fixedly connected to the lower end of the water distributor 31. The upper end of the water distributor 31 is rotatably connected to the housing 1 about a second axis. The water distributor 31 is provided with a dispersion channel (not shown), and one end of the dispersion channel is used to communicate with a clean water tank (not shown) disposed in the accommodating cavity 10 of the housing 1. The other end of the dispersion channel is a plurality of water outlets (not shown) spaced along the axial direction X of the roller brush 2. The cleaning liquid (such as water, or water containing washing liquid) in the clean water tank is sprayed onto the roller brush 2 through the dispersion channel and each water outlet.

[0061] In one embodiment, the first scraper 33 is partially embedded in the roller brush 2.

[0062] Specifically, in the first working mode, the first scraper 33 is partially embedded in the roller brush 2; in the second working mode, the second scraper 5 is spaced apart from the roller brush 2. In the first working mode, the cleaning fluid in the water tank can reach the roller brush 2 via the water distributor 31, wetting the outer cover 21 of the roller brush 2. This is the wet cleaning mode (or mopping mode) of the cleaning device 100. In the second working mode, the cleaning fluid in the water tank is no longer supplied to the roller brush 2, the first scraper 33 can move away from the roller brush 2, and the outer cover 21 of the roller brush 2 can remain dry. This is the dry cleaning mode (or vacuuming mode) of the cleaning device 100.

[0063] For example, please refer to the following: Figures 7 to 9 As shown, in the direction toward the roller brush 2, the end of the first scraper 33 protrudes more than the water distributor 31. This arrangement is intended to ensure that the roller brush 2 rotates when the cleaning fluid is sprayed onto it (see...). Figure 7 and Figure 8 As shown, during the counterclockwise rotation of the roller brush 2, the wastewater that absorbs the stains can be blocked below by the first scraper 33 and returned to the wastewater tank (not shown) through the suction port (not shown) below.

[0064] The roller brush 2 is made of a material that is easily lubricated. For example, the outer layer 21 of the roller brush 2 is a fluff layer, a sponge layer, etc. The fluff layer, sponge layer, etc. are easily deformable, thus allowing the first scraper 33 to be partially embedded therein.

[0065] In one embodiment, in the first operating mode, the depth (radial dimension along the roller brush 2) of the first scraper 33 embedded in the roller brush 2 is not particularly limited. This depends on factors such as the material of the outer coating 21 of the roller brush 2 and the outer dimensions of the roller brush 2, as long as it ensures that the first scraper 33 can effectively scrape away sewage. For example, in the first operating mode, the depth of the first scraper 33 embedded in the roller brush 2 is 1 mm to 3 mm. Optionally, in the first operating mode, the depth of the first scraper 33 embedded in the roller brush 2 is 1 mm to 2 mm. In some embodiments, in the first operating mode, the depth of the first scraper 33 embedded in the roller brush 2 is 1.3 mm, 1.5 mm, 1.7 mm, 2.0 mm, etc.

[0066] In the second operating mode, the distance of the first scraper 33 from the roller brush 2 (the gap dimension along the radial direction of the roller brush 2) is not particularly limited, as long as the first scraper 33 does not affect the rotation of the roller brush 2. For example, in the second operating mode, the distance of the first scraper 33 from the roller brush 2 is 1 mm to 5 mm. Optionally, in the second operating mode, the distance of the first scraper 33 from the roller brush 2 is 2 mm to 5 mm. Optionally, in the second operating mode, the distance of the first scraper 33 from the roller brush 2 is 2 mm to 4 mm. Optionally, in the second operating mode, the distance of the first scraper 33 from the roller brush 2 is 3 mm to 4 mm. In some embodiments, in the second operating mode, the distance of the first scraper 33 from the roller brush 2 is 3 mm, 3.3 mm, 3.5 mm, 3.8 mm, 4.0 mm, etc.

[0067] Please see Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the inner surface of the housing 1 is provided with a support baffle 12 extending along the axial direction X of the roller brush 2, and the roller brush 2 is located on the side of the water channel support 3 opposite to the support baffle 12. The purpose of this arrangement is that at least a portion of the support baffle 12 can serve as a second limiting part 14, such as... Figure 3 , Figure 7 and Figure 8 As shown. That is, when the water channel support 3 is in the second working mode, the water channel support 3 can abut against the side surface of the support wall 12 facing the roller brush 2.

[0068] Since the supporting retaining wall 12 is relatively close to the water channel support 3, the aforementioned first power component 41, transmission component 42, and rope guide component 44 can be installed inside the accommodating cavity 10 of the housing 1, in the space on the side of the supporting retaining wall 12 opposite to the roller brush 2. Please refer to [link / reference]. Figure 1 As shown. Based on this, please refer to... Figure 4As shown, the support retaining wall 12 is provided with a first through hole 121, through which the pull rope 43 passes. In order to accommodate the height change of the water channel support 3 during rotation, the height of the first through hole 121 should be set to be relatively large to avoid frictional contact between the inner wall of the first through hole 121 and the pull rope 43.

[0069] Similarly, the aforementioned clean water tank and wastewater tank can be installed within the accommodating cavity 10 of the housing 1, in the space on the side of the supporting baffle 12 opposite to the roller brush 2. Please continue reading. Figure 4 and Figure 6 As shown, in one embodiment, the supporting retaining wall 12 is further provided with a second through hole 122; as Figure 2 As shown, the water circuit support 3 has a water inlet pipe section 311 on the side opposite to the roller brush 2. The water inlet pipe section 311 passes through the second through hole 122 and is connected to the clean water tank. The water circuit support 3 has a height change during rotation, and correspondingly, the water inlet pipe section 311 will also swing in the height direction. The height of the second through hole 122 is greater than the swing stroke of the water inlet pipe section 311 to accommodate the height change of the water inlet pipe section 311 and avoid frictional contact between the inner wall of the second through hole 122 and the water inlet pipe section 311.

[0070] Please refer to the following: Figure 7 and Figure 8 As shown, in the water channel support 3, the distributor 31 has a receiving groove 313 on the side facing the supporting baffle 12. One end of the reset member 8 is located in the receiving groove 313, and the other end of the reset member 8 is connected to the surface of the supporting baffle 12 facing the roller brush 2. A portion of the reset member 8 is located in the receiving groove 313. The purpose of this arrangement is that the reset member 8 provides a reset force to the water channel support 3 through the support of the supporting baffle 12. For the spring-type reset member 8, since the supporting baffle 12 is relatively close to the water channel support 3, the amount of elastic deformation of the spring is small. Therefore, the spring is more likely to be compressed along its own axis and will not have a torsional problem, that is, the rotational stability of the water channel support 3 is guaranteed.

[0071] Next, please refer to Figure 2 , Figure 7 and Figure 8 As shown, in one embodiment, the cleaning device 100 further includes a second drive assembly 6 and a second scraper 5. The second scraper 5 is disposed within the receiving cavity 10 of the housing 1 and located below the water channel support 3. The end of the second scraper 5 facing the roller brush 2 has a plurality of spaced-apart comb teeth 51 that can at least partially embed into the roller brush 2 (please refer to the reference). Figure 9 As shown, the second drive assembly 6 is disposed in the accommodating cavity 10 of the housing 1 and is used to drive the second scraper 5 to move toward the roller brush 2 and away from the roller brush 2.

[0072] When the second scraper 5 approaches the roller brush 2, the comb teeth 51 of the second scraper 5 can embed into the outer cover layer 21 of the roller brush 2. The purpose of this arrangement is to prevent solid debris such as hair and foreign objects attached to the roller brush 2 from continuing to rotate upward with the roller brush 2. The scraped-off solid debris such as hair and foreign objects are also absorbed into the sewage tank along with the sewage blocked by the first scraper 33.

[0073] The second drive component 6 can either drive the second scraper 5 to move closer to and away from the roller brush 2 in a rotating manner, or drive the second scraper 5 to move closer to and away from the roller brush 2 in a translating manner.

[0074] In one specific embodiment of this application, the second drive component 6 drives the second scraper 5 to move closer to and further away from the roller brush 2 in a translational manner.

[0075] Please see Figure 4 , Figure 6 and Figure 9 As shown, in one embodiment, the inner surface of the housing 1 is provided with at least two guide plates 15, with a guide groove 150 spaced between the guide plates 15, and a portion of the second scraper 5 slides within the guide groove 150. Therefore, by setting the angle of the guide plate 15 relative to the working surface, the translational direction of the second scraper 5 can be determined.

[0076] The number of second guide plates 15 is unlimited; two guide plates 15 form a group to define the guide groove 150. For example... Figure 4 As shown, the surfaces of the guide plates 15 facing each other can be generally parallel to the axial direction X of the roller brush 2. Specifically, the surfaces of the guide plates 15 can be generally parallel to the working surface so that the second scraper 5 can move horizontally. Of course, this is just an example; depending on specific needs, the second scraper 5 can move in an inclined manner relative to the horizontal plane.

[0077] Multiple guide plates 15 can be interconnected as one unit, such as Figure 4 As shown.

[0078] In this embodiment, the second scraper 5 also has two extreme positions: close to the roller brush 2 and far away from the roller brush 2. Specifically, please refer to... Figure 7 and Figure 8 As shown, the second scraper 5 is provided with a limiting groove 53. Please refer to [link / reference]. Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a third limiting part 16 is provided on the inner surface of the housing 1, and the third limiting part 16 is located in the limiting groove 53; in the moving direction of the second scraper 5, the size of the third limiting part 16 is smaller than the size of the limiting groove 53. Therefore, when the third limiting part 16 abuts against the opposite sidewalls of the limiting groove 53, the second scraper 5 reaches the position closest to the roller brush 2 and the position furthest from the roller brush 2, respectively.

[0079] Alternatively, the limiting groove 53 can be set on the inner surface of the housing 1, and the third limiting part 16 can be set on the second scraper 5, as long as the positions of the two are convenient for processing and manufacturing.

[0080] In one embodiment of this application, see [link to embodiment]. Figure 7 As shown, in the first working mode of the cleaning device 100, the distance between the second scraper 5 and the roller brush 2 is the smallest, and in the second working mode of the cleaning device 100, the distance between the second scraper 5 and the roller brush 2 is the largest. That is, in the first working mode, both the first scraper 33 and the second scraper 5 are partially embedded in the roller brush 2, and in the second working mode, both the first scraper 33 and the second scraper 5 are away from the surface of the roller brush 2.

[0081] In the third working mode, the distance between the second scraper 5 and the surface of the roller brush 2 can also have other values, which will not be listed here.

[0082] In the first operating mode, the depth to which the second scraper 5 is embedded in the roller brush 2 (the radial dimension along the roller brush 2) is not particularly limited. This depends on factors such as the material of the outer coating 21 of the roller brush 2 and the outer dimensions of the roller brush 2, as long as it ensures that the second scraper 5 can effectively scrape away solid waste. For example, in the first operating mode, the depth to which the second scraper 5 is embedded in the roller brush 2 is 0.5 mm to 2 mm. Optionally, in the first operating mode, the depth to which the second scraper 5 is embedded in the roller brush 2 is 0.5 mm to 1.5 mm. In some embodiments, in the first operating mode, the depth to which the second scraper 5 is embedded in the roller brush 2 is 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, etc.

[0083] In the second operating mode, the distance of the second scraper 5 from the roller brush 2 (the gap dimension along the radial direction of the roller brush 2) is not particularly limited, as long as the second scraper 5 does not affect the rotation of the roller brush 2. For example, in the second operating mode, the distance of the second scraper 5 from the roller brush 2 is 1 mm to 3 mm. Optionally, in the second operating mode, the distance of the second scraper 5 from the roller brush 2 is 1 mm to 2 mm. In some embodiments, in the second operating mode, the distance of the second scraper 5 from the roller brush 2 is 1 mm, 1.3 mm, 1.5 mm, 1.8 mm, 2.0 mm, etc.

[0084] Please see Figure 7 and Figure 8 As shown, the second scraper 5 has a first connecting part 52 at the end opposite to the roller brush 2; combined with Figure 2 , Figure 7 and Figure 8As shown, the second drive assembly 6 is located on the side of the support wall 12 opposite to the roller brush 2 and includes a second power member 61, a shaft 62, and a second connecting part 63. The second power member 61 is disposed on the inner surface of the housing 1 and connected to the shaft 62, and the second connecting part 63 is fixedly connected to the shaft 62. One of the first connecting part 52 and the second connecting part 63 has a strip-shaped hole 630, and the other has a protruding shaft part 521 that slides within the strip-shaped hole 630. The second power member 61 can be a motor, which drives the shaft 62 to rotate around a third axis, which is also parallel to the first axis. The shaft 62 causes the second connecting part 63 to swing in a plane perpendicular to the third axis. The protruding shaft part 521 slides within the strip-shaped hole 630, converting the rotation of the second connecting part 63 into the translational motion of the second scraper 5. The strip-shaped hole 630 extends substantially perpendicular to the translational direction of the second scraper 5.

[0085] Please refer to the following: Figure 7 and Figure 8 As shown, since the first connecting portion 52 has a certain length, the aforementioned limiting groove 53 can be provided on the first connecting portion 52. The limiting groove 53 can be a blind hole or a through hole. Further optionally, the third limiting portion 16 can be formed on one of the guide plates 15, such as... Figure 5 As shown.

[0086] Please continue reading. Figure 2 , Figure 7 and Figure 8 As shown, the second drive assembly 6 also includes a plurality of fixing parts 64 spaced apart along the axial direction X. The fixing parts 64 are fixedly connected to the side of the support retaining wall 12 opposite to the roller brush 2, and the shaft 62 rotatably passes through each fixing part 64. The purpose of this arrangement is that each fixing part 64 is used to support different positions of the shaft 62, ensuring that the shaft 62 rotates synchronously at all points.

[0087] Please see Figure 9 As shown, in one embodiment, the cleaning device 100 further includes a seal 7, which is disposed within the receiving cavity 10 of the housing 1 and located between the lower surface of the first scraper 33 and the upper surface of the second scraper 5 of the water channel support 3. As the first scraper 33 and the second scraper 5 move away from and towards the roller brush 2, the seal 7 maintains a seal between the lower surface of the first scraper 33 and the upper surface of the second scraper 5. This arrangement aims to prevent wastewater blocked by the first scraper 33 from entering the receiving cavity 10 of the housing 1 through the top of the second scraper 5, thereby preventing wastewater from affecting the first drive assembly 4, the second drive assembly 6, etc., inside the receiving cavity 10 of the housing 1.

[0088] Specifically, please refer to Figure 9As shown, the inner surface of the housing 1 is provided with a support plate 17 located between the water channel support 3 and the second scraper 5, and the sealing member 7 is fixedly disposed on the side of the support plate 17 facing the first scraper 33. Furthermore, based on the linear movement of the second scraper 5, the lower surface of the support plate 17 can be configured to adapt to the movement of the second scraper 5, that is, the lower surface of the support plate 17 and the second scraper 5 maintain sliding contact to achieve sliding sealing.

[0089] Alternatively, in other embodiments, the sealing element 7 can be disposed at the lower end of the support plate 17 for sealing connection with the upper surface of the second scraper 5. In this case, the upper surface of the support plate 17 is designed to adapt to the rotation of the first scraper 33 and slide against the first scraper 33 during the rotation of the first scraper 33.

[0090] The specific material of the seal 7 is not limited; it can be a flexible plastic part, a flexible rubber part, or a flexible silicone part, etc. The seal 7 extends along the axial direction X.

[0091] In one specific embodiment of this application, the support plate 17 is provided with a slot 170, and the lower end of the seal 7 is located in the slot 170. The seal 7 can be interference-fitted into the slot 170, or pasted into the slot 170, or a combination of interference fit and pasting, etc. The method is not limited, as long as it ensures that the seal 7 is stably installed on the support plate 17 and is not easy to fall off.

[0092] In one embodiment of this application, please refer to the following: Figure 6 and Figure 9 As shown, the support plate 17 can serve as one of the guide plates 15, for example, it can be a guide plate 15 located above the second scraper 5. In the axial direction X, multiple guide plates 15 located above the second seal 7 can be connected to each other for sliding contact with the upper surface of the second scraper 5.

[0093] To further enhance the adaptability of the cleaning device 100 in different scenarios, in one embodiment, at least the outer cover 21 of the roller brush 2 is removable and replaceable. For example, please refer to... Figure 7 and Figure 8As shown, the outer cover 21 of the roller brush 2 is removable, while the roller brush bracket 22 is not removable. Alternatively, the roller brush bracket 22, together with the outer cover 21, is detachably mounted on the housing 1. This design allows the cleaning device 100 to be adapted to different floor materials and operating modes by replacing the roller brush 2 with different materials or the outer cover 21. For example, in the first operating mode, the cleaning device 100 is in wet cleaning mode. In this mode, the outer cover 21 can be made of a highly absorbent material, such as the aforementioned pile layer or sponge layer. In the second operating mode, the cleaning device 100 is in dry cleaning mode. In this mode, the outer cover 21 of the roller brush 2 can be made of a material with good toughness and elasticity to effectively remove debris from the floor, such as the brush layer. Furthermore, the friction between the brush layer and various floor and carpet surfaces is relatively low. Therefore, the cleaning device 100 can adapt to cleaning more surfaces in the second operating mode, with a lower workload, which helps extend its service life and reduce power consumption.

[0094] Furthermore, the cleaning device 100 provided in this application embodiment may also include a third drive assembly (not shown) disposed within the receiving cavity 10 of the housing 1, the third drive assembly being used to drive the roller brush 2 to rotate. When the cleaning device 100 is a self-moving cleaning device, it may also include a walking assembly and a fourth drive assembly (both not shown) disposed at the bottom of the housing 1, the fourth drive assembly being used to drive the walking assembly to move, thereby realizing the self-movement of the cleaning device 100.

[0095] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
