[0081] The embodiments of the present disclosure provide a cleaning device, such as a floor scrubber. It should be noted that the present disclosure describes the cleaning device through a floor scrubber only as a preferred embodiment of the present disclosure, and does not limit the protection scope of the cleaning device of the present disclosure. For example, the cleaning device of the present disclosure may be a handheld floor scrubber with a handle and manually operated by a user, or a handheld floor sweeper with a handle and manually operated by a user.

[0082] In the following, the embodiments of the present disclosure will be described in detail by taking a handheld floor scrubber as an example of the cleaning device.

[0083] Specifically, Figure 1 to Figure 3 As shown, the handheld floor scrubber includes a body 10, a floor brush assembly 20 and a shaft assembly 30. The floor brush assembly 20 is provided with components for cleaning the floor, such as a cleaning roller. When the floor brush assembly 20 cleans the floor to be cleaned, it is necessary to suck the cleaned sewage and debris into the sewage tank 110 of the sewage suction assembly through the sewage suction assembly; the sewage tank 110 is usually arranged on the body 10 to reduce the volume of the floor brush assembly 20 and reduce the weight of the floor brush assembly 20, thereby improving the flexibility of the floor brush assembly 20, and further improving the cleaning effect on the floor; therefore, the shaft assembly 30 needs to simultaneously realize the function of rotatably connecting the body 10 and the floor brush assembly 20, and connecting the sewage suction port on the floor brush assembly 20 with the sewage tank 110.

[0084] In one embodiment of the present disclosure, Figure 5 to Figure 12 As shown, the shaft assembly 30 includes: a first joint member 310, an air guide duct 320, a second joint member 330 and a shaft member 340, the first joint member 310 includes a first air inlet 311, a first air outlet 312 and a first air duct located between the first air inlet 311 and the first air outlet 312; the second joint member 330 includes a second air inlet 331, a second air outlet 332 and a second air duct located between the second air inlet 331 and the second air outlet 332; The air duct 320 includes a third air inlet 321, a third air outlet 322 and a third air duct located between the third air inlet 321 and the third air outlet 322. The third air inlet 321 is connected to the first air outlet 312, and the third air outlet 322 is connected to the second air inlet 331. The rotating shaft 340 is formed with a first through hole 341, and the first joint member 310, the air duct 320 and the second joint member 330 are connected and then passed through the first through hole 341 of the rotating shaft member 340.

[0085] The second joint member 330 can be rotated between the vertical position and the horizontal position through the rotating shaft member 340. When the second joint member 330 is in the vertical position, the first angle between the connection surface of the second joint member 330 and the air duct 320 and the cleaning surface of the cleaning device on the side close to the second joint member 330 and in the forward direction of the cleaning device is an obtuse angle, that is, the first angle between the central axis of the air duct 320 and the plane where the third air outlet 322 on the air duct 320 is located is an obtuse angle in the direction of the air duct 320 converting from the vertical position to the horizontal position and in the direction toward the second joint member 330, that is, the connection surface between the air duct 320 and the second joint member 330 is an obtuse angle. Among them, the cleaning surface of the cleaning device is the cleaning surface provided by the cleaning roller brush in the floor brush assembly 20. After the cleaning surface of the floor brush assembly 20 contacts the surface to be cleaned, the cleaning surface of the floor brush assembly 20 is parallel or basically parallel to the surface to be cleaned, so as to perform cleaning operations on the surface to be cleaned; the forward direction of the cleaning device is the direction in which the user manually pushes the cleaning device forward when the cleaning device is in use.

[0086] The rotating shaft assembly 30 provided in the present disclosure is connected with the second connecting member 310, the air guide pipe 320 and the second connecting member 330, so that the first air duct, the second air duct and the third air duct are connected, so that the function of connecting the sewage suction port on the floor brush assembly 20 and the sewage tank 110 is realized through the rotating shaft assembly 30; the second connecting member 330 can be rotated between the vertical position and the lying position through the rotating shaft member 340, and then the air guide pipe 320 can be switched between the vertical position and the lying position under the drive of the rotating shaft member 340, providing a flexible air guide channel; the first connecting member 310, the air guide pipe 320 and the second connecting member 330 are connected and then penetrated into In the first through hole 341 of the rotating shaft member 340, the rotating shaft member 340 is rotatably connected to the floor brush assembly 20; when the rotating shaft member 340 and the floor brush assembly 20 rotate relative to each other, the air duct 320 can be driven to rotate, thereby achieving the purpose of rotating the machine body 10 relative to the floor brush assembly 20; since the first angle between the central axis of the air duct 320 and the plane where the third air outlet 322 on the air duct 320 is located is an obtuse angle in the direction in which the air duct 320 is converted from the vertical position to the lying position and in the direction toward the second joint member 330, the air duct 320 can be driven by the rotating shaft member 340 to rotate between the vertical position and the lying position, such as Figure 1 and Figure 4 As shown, the machine body 10 can be switched between an upright position and a lying position relative to the floor brush assembly 20, thereby improving the flexibility of the floor brush assembly 20 during cleaning operations.

[0087] like Figure 13 to Figure 15 As shown, the shaft assembly 30 also includes: a third joint member 350, the third joint member 350 is formed with a second through hole 352, and the first joint member 310, the air duct 320 and the second joint member 330 are connected and then passed through the second through hole 352 of the shaft member 340; the third joint member 350 is located on the side of the shaft member 340 close to the second joint member 330.

[0088] Among them, the third joint member 350 includes an opposite first end and a second end, the second through hole 352 connects the first end and the second end of the third joint member 350, the first end of the third joint member 350 is rotatably connected to the shaft member 340, the third air outlet 322 of the air duct 320 is rotatably connected to the second air inlet 331 of the second joint member 330, that is, the shaft assembly 30 can be regarded as two groups of components connected in rotation; the second end of the third joint member 350 is fixedly connected to the body 10, and by controlling the body 10, the body 10 can be swung in the left and right directions relative to the floor brush assembly 20, thereby further improving the flexibility of the floor brush assembly 20 when cleaning the floor.

[0089] When the second joint member 330 is in the vertical position, the second angle between the rotating surface of the third joint member 350 and the rotating shaft member 340 and the cleaning surface of the cleaning device on the side close to the third joint member 350 and in the forward direction of the cleaning device is an obtuse angle, that is, the second angle between the rotating surface of the third joint member 350 and the rotating shaft member 340 and the central axis of the air duct 320 is an obtuse angle in the direction of the air duct 320 switching from the vertical position to the lying position and in the direction toward the second joint member 330. By making the second angle between the rotating surface of the third joint member 350 and the rotating shaft member 340 and the central axis of the air duct 320 an obtuse angle, that is, the rotating surface of the third joint member 350 and the rotating shaft member 340 is an inclined surface, the angle between the machine body 10 and the central axis of the third joint member 350 and the central axis of the machine body 10 is relatively small, for example, 5° to 20°, so that the machine body 10 can be relatively located in the lying position relative to the brush assembly 20 through the rotation of the rotating shaft assembly 30. At the same time, by making the rotating surface of the third joint member 350 rotatably connected to the rotating shaft member 340 an inclined surface, that is, the driving surface in the rotating assembly is an inclined surface, the rotation of the floor brush assembly 20 relative to the body 10 is relatively flexible when the body 10 is in the lying position.

[0090] The first angle may be equal to the second angle, that is, the rotational surface of the third joint member 350 and the rotating shaft member 340 is parallel to the rotational surface of the third air outlet 322 of the air duct 320 and the second air inlet 331 of the second joint member 330, further improving the flexibility when driven to rotate by the machine body 10. Of course, the first angle and the second angle may also be different, and the present disclosure does not limit this.

[0091] like Figure 5 and Fig.10 As shown, the second joint member 330 includes a first body section 333 and a second body section 334, the first body section 333 is connected to the second body section 334, and the central axes of the first body section 333 and the second body section 334 intersect; the second air inlet 331 is located on the first body section 333, and the second air outlet 332 is located on the second body section 334.

[0092] The central axis of the first body section 333 intersects with the central axis of the rotating shaft 340; or, the central axis of the first body section 333 intersects with the central axis of the third joint member 350; or, the central axis of the first body section 333 intersects with the central axis of the rotating shaft 340 and the central axis of the third joint member 350. By making the central axis of the first body section 333 intersect with the central axis of the rotating shaft 340 or the central axis of the third joint member 350, the rotational surface of the third air outlet 322 of the air duct 320 and the second air inlet 331 of the second joint member 330 can be made an inclined surface; at the same time, the angle between the central axis of the machine body 10 and the central axis of the third joint member 350 and the central axis of the machine body 10 can be made relatively small, thereby facilitating the flexibility of the machine body 10 when it is in a lying position relative to the floor brush assembly 20, and facilitating the floor brush assembly 20 to clean the floor.

[0093] The central axis of the rotating shaft 340 is parallel to the central axis of the third joint 350, and the rotating shaft 340 and the third joint 350 can be coaxially arranged to improve the flexibility of the third joint 350 and the rotating shaft 340 relative to each other. Of course, the central axis of the rotating shaft 340 and the central axis of the third joint 350 can be arranged non-parallel, for example, the central axis of the rotating shaft 340 and the central axis of the third joint 350 have a small angle, which is not limited in the present disclosure.

[0094] Specifically, the air duct 320 includes: an air duct body 323 and a fourth joint member 324, the fourth joint member 324 includes an opposite first end and a second end, the first end of the fourth joint member 324 is rotatably connected to the second air inlet 331 of the second joint member 330, and the second end of the fourth joint member 324 is bonded to one end of the air duct body 323. By setting the fourth joint piece 324, the connection between the air duct body 323 and the second joint piece 330 is achieved; the air outlet end of the air duct body 323 can be bonded to the first end of the fourth joint piece 324; the air duct body 323 can be inserted into the first end of the fourth joint piece 324, and the air duct body 323 and the fourth joint piece 324 are bonded by applying adhesive or double-sided tape between the air duct body 323 and the fourth joint piece 324; through bonding, the number of components of the shaft assembly 30 is reduced, the production cost is reduced, the assembly effect and maintenance economy are improved, and at the same time, the connection reliability between the air duct body 323 and the fourth joint piece 324 is improved.

[0095] Among them, Fig.11As shown, the fourth joint member 324 can be connected to the rotating shaft member 340, that is, the fourth joint member 324 and the rotating shaft member 340 can be an integrated joint, which reduces the number of components of the rotating shaft assembly 30 and improves the connection strength between the rotating shaft member 340 and the fourth joint member 324. Of course, the fourth joint member 324 and the rotating shaft member 340 can also be a separate structure, and can be connected together by bonding, welding, clamping, threaded connection, etc., and the present disclosure does not limit this.

[0096] like Figure 5 and Figure 6 As shown, the shaft assembly 30 further includes a buckle 360. After the first end of the fourth joint member 324 is rotatably connected to the second air inlet 331 of the second joint member 330, the buckle 360 ​​is simultaneously buckled at the connection between the fourth joint member 324 and the second joint member 330 to form a restriction on the axial separation of the fourth joint member 324 and the second joint member 330, thereby rotatably connecting the fourth joint member 324 and the second joint member 330 together.

[0097] The buckle 360 ​​includes a first buckle part and a second buckle part. The first buckle part and the second buckle part are matched and sleeved at the connection between the fourth joint part 324 and the second joint part 330, and the relative rotation between the fourth joint part 324 and the second joint part 330 is not affected.

[0104] In yet another embodiment, the air duct 320 and the second connector 330 are axially clamped to form a restriction on the separation of the air duct 320 and the second connector 330 in the axial direction.

[0106] Among them, the first locking groove 326 can be an annular groove, and the first locking protrusion 336 can be an annular protrusion or a protrusion arranged at intervals. The present disclosure does not impose any restrictions on this. It is sufficient to achieve radial limitation of the connection position between the fourth connector 324 and the second connector 330.

[0107] like Fig.24 As shown, a first card slot 326 and a third card protrusion 327 are formed on the end of the fourth joint member 324 of the duct wind 320, and the notch of the first card slot 326 faces the inner side of the fourth joint member 324; a first card protrusion 336 and a second card protrusion 337 are formed on the end of the second joint member 330, and the first card protrusion 336 and the second card protrusion 337 extend toward the periphery of the second joint member 330, and a second card slot 338 is formed between the first card protrusion 336 and the second card protrusion 337, and the notch of the second card slot 338 faces the inner side of the fourth joint member 324.

[0109] It should be noted that, in the present disclosure, when the fourth joint member 324 and the second joint member 330 are rotationally connected, the structure for limiting the axial separation of the fourth joint member 324 and the second joint member 330 is not limited to the technical solutions provided in the above-mentioned embodiments of the present disclosure, and any structure that can realize the connection position between the fourth joint member 324 and the second joint member 330 being at the radial upper limit position falls within the protection scope of the present disclosure.

[0110] Specifically, one end of the air duct body 323 forming the third air inlet 321 is bonded to the first air outlet 312 of the first connector 310. One end of the air duct body 323 forming the third air inlet 321 can extend into the first air duct through the first air outlet 312 of the first connector 310, and the air duct body 323 and the first connector 310 are bonded by applying adhesive or double-sided adhesive between the air duct 320 and the first connector 310; through bonding, the number of components of the rotating shaft assembly 30 is reduced, the production cost is reduced, the assembly effect and maintenance economy are improved, and the connection reliability between the air duct body 323 and the fourth connector 324 is improved.

[0111] The air duct body 323 may be a flexible tube, such as a plastic corrugated tube, to improve the bending performance and service life of the air duct body 323. Of course, the air duct body 323 may also be a smooth plastic hose, or may be a bendable joint-type hard tube formed by connecting multiple hard joints together, as long as the air duct body 323 can achieve the bending function, and the present disclosure does not limit this.

[0112] like Fig.11 and Fig.12 As shown, the rotating shaft member 340 includes a main body portion 343, a first rotating shaft portion 344 and a second rotating shaft portion 345. The main body portion 343 forms a first through hole 341. The first rotating shaft portion 344 and the second rotating shaft portion 345 are located on two opposite sides of the main body portion 343 in the radial direction. The first rotating shaft portion 344 and the second rotating shaft portion 345 are rotatably connected to the floor brush assembly 20, thereby realizing the pivot connection between the rotating shaft assembly 30 and the floor brush assembly 20; the body 10 can swing left and right and front and back through the rotating shaft assembly 30, thereby improving the flexibility of relative movement between the body 10 and the floor brush assembly 20.

[0113] Among them, Fig.13 As shown, a rotating shaft member 340 is provided with a rotating shaft connecting member 342, one end of the rotating shaft connecting member 342 is fixedly connected to the main body 343, and the other end of the rotating shaft connecting member 342 is rotatably connected to the third joint member 350, thereby realizing the rotatable connection between the rotating shaft member 340 and the third joint member 350.

[0114] In one embodiment of the present disclosure, a cleaning device is provided, such as Figure 1 to Figure 5 As shown, the cleaning device includes: a body 10, a floor brush assembly 20 and a shaft assembly 30 provided in the above embodiment. The body 10 and the floor brush assembly 20 are rotatably connected via the shaft assembly 30 so that the body 10 can switch between a standing position and a lying position.

[0115] like Fig.13 Fig.16 As shown, a positioning portion 351 is provided on the third joint member 350; the floor brush assembly 20 includes a shell 210, and a positioning groove 220 is formed on the shell 210; when the body 10 is in the vertical position, the positioning portion 351 is located in the positioning groove 220, forming a restriction on the swinging of the body 10 in the left and right directions when the body 10 is in the vertical position.

[0116] like Fig.17 and Fig.18As shown, a protrusion 346 is provided on the outer circumference of the first rotating shaft portion 344 and the second rotating shaft portion 345, and a trigger switch 230 is provided in the floor brush assembly 20. When the machine body 10 leaves the vertical position, the protrusion 346 triggers the trigger switch 230. By providing the protrusion 346 and the trigger switch 230, a convenient switch of the floor brush assembly 20 is realized; when it is not needed, the machine body 10 is in the vertical position, and the protrusion 346 abuts against the trigger switch 230, so that the trigger switch 230 is in a closed state; when the cleaning device needs to be used, the machine body 10 rotates relative to the floor brush assembly 20 and leaves the vertical position, and the protrusion 346 separates from the trigger switch 230, so that the trigger switch 230 is in an open state, and the floor brush assembly 20 starts to work to clean the floor.

[0117] By providing protrusions 346 on the outer circumferential surfaces of the first rotating shaft portion 344 and the second rotating shaft portion 345, no matter whether the trigger switch 230 is located on the left side or the right side of the rotating shaft assembly 30, the rotating shaft member 340 can cooperate with the trigger switch 230, thereby improving the adaptability of the rotating shaft member 340.

[0118] Among them, Figure 8 As shown, the outer circumferences of the first rotating shaft portion 344 and the second rotating shaft portion 345 are respectively provided with protrusions 346, and the protrusions 346 on the outer circumferences of the first rotating shaft portion 344 and the second rotating shaft portion 345 are symmetrically arranged relative to the body portion 343. The protrusions 346 on the outer circumferences of the first rotating shaft portion 344 and the second rotating shaft portion 345 are symmetrically arranged relative to the body portion 343, so as to facilitate the cooperation with the trigger switch 230 in the floor brush assembly 20. Of course, the protrusions 346 may also be arranged only on the outer circumference of the first rotating shaft portion 344 or the second rotating shaft portion 345, and the present disclosure does not limit this.

[0119] like Fig.19 As shown, the trigger switch 230 includes a switch body 231, an elastic arm 232 connected to the switch body 231, and a contact point 233 provided on the switch body 231. The elastic arm 232 and the trigger point 233 can be positive and negative. When the cleaning device is not needed, the body 10 is in a vertical position, and the protrusion 346 abuts against the trigger switch 230, so that the elastic arm 232 abuts against the contact point, so that the trigger switch 230 is in a closed state; when the cleaning device needs to be used, the body 10 rotates relative to the brush assembly 20 and leaves the vertical position, and the protrusion 346 separates from the elastic arm 232, so that the elastic arm 232 recovers elastic deformation and is separated from the trigger point, so that the trigger switch 230 is in an open state.

[0120] In addition, a trigger switch 230 with multiple trigger points can be provided so that the trigger switch 230 can be turned on or off when the protrusion 346 triggers different points. Of course, a photoelectric sensor switch can also be provided to turn the switch on or off by judging the position of the protrusion 346; this is not shown in the present disclosure, and all technical solutions for the conversion of switch types belong to the protection scope of the present disclosure.

[0121] Among them, the trigger switch 230 can control the operation of the floor brush assembly 20. For example, after the trigger switch 230 is triggered by rotating the body 10, the floor brush assembly 20 can start the working state to rotate the cleaning roller brush to clean the surface to be cleaned; or, after triggering the trigger switch 230, the whole machine can be controlled to work, for example, the fan in the dirt suction assembly on the body 10 works, and the liquid supply pump in the floor brush assembly 20 works; of course, the trigger switch 230 can also control the opening and closing of some devices, so as to cooperate with other switch devices through the trigger switch 230 to realize the whole machine control of the cleaning equipment, and the present disclosure does not limit this.

[0122] like Fig.17 As shown, the outer circumferential surfaces of the first rotating shaft portion 344 and the second rotating shaft portion 345 are provided with a limiting protrusion 347 in the circumferential direction, and the floor brush assembly 20 is provided with a damping assembly 240. When the machine body 10 is in the vertical position, the damping assembly 240 forms a damping for the limiting protrusion 347 to rotate toward the rotation direction of the rotating shaft 340, so that the machine body 10 can be relatively stable in the vertical position when it is not necessary to rotate; when the machine body 10 needs to leave the vertical position for rotation, the machine body 10 can be rotated by external force, so that the machine body 10 overcomes the damping provided by the damping assembly 240 and rotates toward the lying position.

[0123] Specifically, Fig. 20 and Fig.21 As shown, the damping assembly 240 includes an elastic member 242 and a damping block 241, and the damping block 241 is disposed on the elastic member 242. When the machine body 10 rotates from the upright position toward the lying position, the first limiting protrusion 347 squeezes the damping block 241. When the external force applied to the machine body 10 is greater than the damping provided by the elastic member 242, the damping block 241 is compressed by the elastic member 242 and retracts, so that the first limiting protrusion 347 bypasses the damping block 241.

[0124] Among them, the size of the damping can be adjusted by adjusting the compression ratio of the elastic member 242; the damping assembly 240 corresponding to the first shaft portion 344 and the second shaft portion 345 can be exactly the same, so as to reduce the number of accessory types, reduce production costs, and improve assembly efficiency.

[0125] Of course, the limiting protrusion 347 may be provided only on the outer circumferential surface of the first rotating shaft portion 344 along the circumferential direction, or the limiting protrusion 347 may be provided only on the outer circumferential surface of the second rotating shaft portion 345 along the circumferential direction, and the present disclosure does not make any limitation to this.

[0126] Among them, Fig. 20 and Fig.21 As shown, the damping assembly 240 also includes a guide member 243, which is formed with a guide groove. The guide member 243 is fixedly installed in the floor brush assembly 20 and is in an extrusion position; when the damping block 241 is squeezed by the limiting protrusion 347, the damping block 241 can move downward in the guide groove of the guide member 243; when the damping block 241 is not squeezed by the limiting protrusion 347, the damping block 241 moves upward along the guide groove under the action of the elastic restoring force of the elastic member 242 and returns to the damping position.

[0127] The elastic member 242 may be a spring, the elastic force of which is linear and has high reliability. Of course, the elastic member 242 may also be a rubber member or other elastic structural member, which is not limited in the present disclosure.

[0128] like Fig.11 and Fig.12 As shown, a stop protrusion 348 is further provided on the outer circumference of the first rotating shaft portion 344 and the second rotating shaft portion 345. When the machine body 10 rotates from the lying position to the standing position, the stop protrusion 348 abuts against the structure in the floor brush assembly 20, forming a restriction on the machine body 10 to continue to rotate away from the lying position, so that the machine body 10 is located in the standing position, thereby forming a positioning of the machine body 10 in the standing position, facilitating the use of the user and improving the convenience of use; at the same time, it prevents the machine body 10 from continuing to rotate from the standing position to the direction away from the lying position, thereby improving the reliability of the cleaning device.

[0129] Among them, the outer circumferences of the first rotating shaft portion 344 and the second rotating shaft portion 345 are both provided with stop protrusions 348, that is, the first rotating shaft portion 344 and the second rotating shaft portion 345 on both sides can achieve rotation limit through the stop protrusions 348, thereby improving the positioning effect of the machine body 10 when it is in the vertical position. Of course, the stop protrusion 348 can also be provided on only the outer circumference of one of the first rotating shaft portion 344 and the second rotating shaft portion 345, and the present disclosure does not limit this.

[0130] Among them, the structure in the floor brush assembly 20 that abuts against the stop protrusion 348 can be the guide member 243 in the damping assembly 240, and the guide member 243 is fixedly installed in the floor brush assembly 20. The limiting protrusion 347 cooperates with the damping block 241 in the guide member 243 to realize the damping of the body 10 in the vertical position; when the body 10 rotates toward the vertical position, the stop protrusion 348 can abut against the opening side of the guide member 243 to form a limit for the continued rotation of the body 10, thereby forming the positioning of the body 10 in the vertical position. Of course, the stop protrusion 348 can also abut against other structural members fixedly set in the floor brush assembly 20 to realize the limiting effect, such as the bottom shell of the floor brush assembly 20, or the abutment structure independently set in the floor brush assembly 20, which can cooperate with the stop protrusion 348 to form a limit for the body 10 in the vertical position, and the present disclosure does not limit this.

[0131] Specifically, a handle assembly may be further provided on the machine body 10, and the handle assembly is connected to one end of the machine body 10 away from the floor brush assembly 20, for the user to operate and hold. The user holds the handle assembly to manipulate the floor brush assembly 20 to perform cleaning tasks on the cleaned surface, such as the ground.

[0132] Among them, the body 10 extends longitudinally, the handle assembly is connected to the upper end of the body 10, and the floor brush assembly 20 is connected to the lower end of the body 10. The body 10 and the floor brush assembly 20 are rotatably connected so that the handle assembly and the body 10 can rotate relative to the floor brush assembly 20, thereby changing the operating angle and flexibly adjusting the cleaning posture.

[0133] Specifically, the floor brush assembly 20 includes a cleaning component located at the bottom thereof, such as a cleaning roller brush. The number of the cleaning roller brushes is, for example, one or more, such as two, and the cleaning roller brushes can rotate at high speed to scrub the floor.

[0134] Specifically, Figure 2 As shown, the cleaning device further includes a clean water tank 120. The clean water tank 120 and the sewage tank 110 are both arranged on the machine body 10. The clean water tank 120 contains cleaning liquid, such as clean water, which can provide clean water to the cleaning roller through a clean water pipeline to wet the surface of the cleaning roller, so that the cleaning roller can perform wet cleaning on the cleaned surface. When the cleaning roller performs wet cleaning, sewage will be generated on the cleaned surface, and the sewage can be recycled to the sewage tank 110 through a sewage recycling pipeline.

[0135] Specifically, the cleaning device further includes a fan, which is disposed in the body 10 and configured to allow airflow to flow in the air duct to provide power for recycling sewage; under the action of the suction force generated by the fan, the sewage is sucked through the air duct into the sewage tank 110. After the cleaning device completes the cleaning operation, the sewage collected in the sewage tank 110 of the cleaning device can be poured out, and the entire air duct in the cleaning device, especially the sewage recycling air duct and the sewage tank 110, is in a dry state to avoid the breeding of undesirable and other filth.
