For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0039] As shown in Figures 1 to 7, the cleaning device 300 provided in an embodiment of the present application includes a body assembly 310, a dust collection assembly 320, a fan 330, and an air duct assembly 340. The body assembly 310 forms an assembly space, and the body assembly 310 is provided with an exhaust port 312 connected to the outside. The dust collection assembly 320 includes an inner shell 321 and a dust collection box 100 mounted on the inner shell 321. The inner shell 321 is fixedly mounted on the body assembly 310 and is located in the assembly space. The inner shell 321 is provided with a first air inlet and a first air outlet 3212, both of which are connected to the dust collection box 100. The fan 330 is fixedly installed on the fuselage assembly 310 and is located in the assembly space. The fan 330 has an air flow inlet 331 and an air flow outlet 332. The air flow inlet 331 is connected to the first air outlet 3212, and a first elastic member 351 is provided between the periphery of the air flow inlet 331 and the periphery of the first air outlet 3212. The first elastic member 351 is clamped between the periphery of the air flow inlet 331 and the periphery of the first air outlet 3212, so that the first elastic member 351 is clamped to produce elastic deformation to achieve a sealing setting between the air flow inlet 331 and the first air outlet 3212. The air duct assembly 340 is located in the assembly space. The air duct assembly 340 has an inlet end 341 and an outlet end 342. The inlet end 341 is connected to the fan 330, and the inlet end 341 is connected to the air flow outlet 332. The outlet end 342 is connected to the fuselage assembly 310 through the second elastic member 352, and the outlet end 342 extends to the inner wall of the assembly space and is connected to the exhaust port 312.

[0040] The operation of the fan 330 of the cleaning device of the present application drives airflow, thereby carrying debris, garbage, and dust on the ground into the interior of the dust collection box 100 of the dust collection assembly 320. The debris, garbage, and dust are intercepted in the dust collection box 100, and then the clean airflow flows along the air duct assembly 340 to the exhaust port 312 and is discharged to the outside. A first elastic member 351 is provided between the periphery of the air flow inlet 331 of the fan 330 and the periphery of the first air outlet 3212, and the outlet end 342 of the air duct assembly 340 is connected to the fuselage assembly 310 via a second elastic member 352. The inlet end 341 of the air duct assembly 340 is connected to the fan 330, and the inlet end 341 is connected to the air flow outlet 332 of the fan 330. In other words, the front and rear ends of the entire assembly of the fan 330 and the air duct assembly 340 are respectively cushioned and reduced in vibration by the first elastic member 351 and the second elastic member 352. Therefore, during the operation of the fan 330, the vibration generated by the fan 330 is buffered and reduced when it is transmitted to the first elastic member 351 and the second elastic member 352, thereby reducing the energy of the subsequent vibration transmission and significantly reducing the impact of the vibration generated by the fan 330 on the entire cleaning device, thereby achieving a noise reduction and silencing effect on the cleaning device. In addition, the vibration transmission to the body assembly 310 is reduced, thereby reducing the risk of loosening of the connection structure within the cleaning device.

[0041] As shown in Figures 2 to 4, the second elastic member 352 is fixedly mounted on the outlet end 342. As shown in Figure 3, the fuselage assembly 310 is provided with two opposite insertion columns 313, and both insertion columns 313 are provided with vertical slots. The opposite side edge areas of the elastic member are respectively inserted into the vertical slots of the two insertion columns 313. By inserting and matching the vertical slots of the insertion columns 313 with the side areas of the second elastic member 352, after the second elastic member 352 is firmly mounted on the outlet end 342 of the air duct assembly 340, the second elastic member 352 can be easily and quickly installed on the insertion columns 313, with high installation efficiency, and convenient for subsequent disassembly, cleaning, maintenance, replacement, and other operations of the air duct assembly 340.

[0042] As shown in Figures 2 and 4, the body assembly 310 includes a frame 314 and a housing 315. The housing 315 covers the frame 314 to form an assembly space, and the exhaust port 312 is located in the housing 315. When the housing 315 covers the frame 314, the second elastic member 352 seals against the peripheral sidewalls of the exhaust port 312 of the housing 315, thereby achieving a seal between the outlet end 342 and the exhaust port 312. In an embodiment of the present application, the second elastic member 352 can exert a counterpressure against the inner wall of the housing 315, causing slight elastic deformation of the second elastic member 352, thereby achieving a seal between the outlet end 342 and the exhaust port 312. Alternatively, the second elastic member 352 and the inner wall of the housing 315 can be sealed using a sealant injection. After the sealant cures, it can be hot-melted or directly torn off, thereby facilitating separation of the housing 315 and the second elastic member 352.

[0043] As shown in FIG6 , the airflow outlet 332 includes a first outlet 3321 and a second outlet 3322 that are opposite each other. As shown in FIG3 to FIG7 , the air duct assembly 340 includes a first air duct tube 343 and a second air duct tube 344. The inlet end 341 of the first air duct tube 343 communicates with the first outlet 3321, and the inlet end 341 of the second air duct tube 344 communicates with the second outlet 3322. Furthermore, the outlet ends 342 of the first air duct tube 343 and the second air duct tube 344 are both connected to the body assembly 310 via a second elastic member 352. In an embodiment of the present application, two relative air ducts, a first air duct tube 343 and a second air duct tube 344, are designed to divide the airflow blown from the fan 330 into two paths and flow along the first air duct tube 343 and the second air duct tube 344 to the exhaust port 312. The airflow of the airflow outlet 332 of the fan 330 is blown into the first air duct tube 343 and the second air duct tube 344 along the tangential direction. This can effectively reduce the along-the-line resistance encountered by the airflow flowing in the air duct assembly 340, effectively reduce the vortex generated by the airflow flow, and then achieve a significant noise reduction effect.

[0044] To reduce noise caused by airflow, as shown in Figures 6 and 7 , the cleaning device 300 further includes a first sound-absorbing cotton pad 353, which is attached to the inner wall of the air duct assembly 340. When air flows through the first and second air duct tubes 343 and 344 and hits the first sound-absorbing cotton pad 353, the first sound-absorbing cotton pad 353 effectively absorbs the impact energy of the airflow, thereby achieving noise reduction.

[0045] To further reduce the noise caused by airflow, as shown in Figures 6 and 7 , the cleaning device 300 further includes a second silencer 354. The second silencer 354 is attached to the inner wall of the airflow outlet 332 of the fan 330, so that the airflow blown to the airflow outlet 332 by the fan 330 is blown toward the second silencer 354. When the airflow is blown toward the airflow outlet 332 by the fan 330, the airflow will hit the second silencer 354, which can absorb the impact of the airflow at this time, thereby achieving noise reduction.

[0046] As shown in Figures 8 to 12, the dust collection box 100 provided in the embodiment of the present application includes a dust collection box body 10 and a filter assembly 20. The dust collection box body 10 is formed with a dust collection chamber 11, and is provided with a mounting opening 12, a second air inlet 13, and a second air outlet 14. The mounting opening 12, the second air inlet 13, and the second air outlet 14 are all connected to the dust collection chamber 11. The edge of the mounting opening 12 is provided with a plurality of first locking structures 15 spaced apart. The filter assembly 20 includes a cover 21 and a filter 22. The filter 22 is connected to the cover 21, which covers the mounting opening 12. The filter 22 extends into the dust collection chamber 11 to separate the second air inlet 13 from the second air outlet 14. Airflow flows from the second air inlet 13 to the filter 22, so that debris, garbage, and dust carried by the airflow are intercepted by the filter 22. The clean airflow passing through the filter 22 is then blown out from the second air outlet 14. The cover 21 is provided with a plurality of spaced-apart second locking structures 23, each corresponding to the plurality of first locking structures 15. When the cover 21 is closed over the mounting opening 12, rotating the cover 21 in a forward direction S about its central axis locks the second locking structures 23 with the first locking structures 15. Rotating the cover 21 in a reverse direction about its central axis unlocks the second locking structures 23 from the first locking structures 15.

[0047] The dust box 100 provided in the present application is assembled on the cleaning device 300 to intercept debris, garbage and dust carried by the airflow sucked by the cleaning device 300, thereby achieving the purpose of dust collection and cleaning. In the dust box 100, when the cover 21 of the filter assembly 20 is closed on the installation opening 12, the cover 21 is rotated in the positive direction S around the central axis of the cover 21 so that the second locking structure 23 and the first locking structure 15 are locked with each other, thereby simply and quickly installing the filter assembly 20 on the dust box body 10. On the other hand, when it is desired to remove the filter assembly 20 from the dust box body 10, the cover 21 is rotated in the opposite direction around the central axis of the cover 21 so that the second locking structure 23 and the first locking structure 15 are unlocked, and the filter assembly 20 can be removed from the dust box body 10. The disassembly process is simple and quick. Compared with current cleaning robots, when disassembling and assembling the dust box 100 of the cleaning device 300 provided in this application, only two steps, namely turning and lifting, are required to remove the filter assembly 20 from the dust box body 10. There is no need to perform complicated steps of disassembling and assembling other parts. The disassembly and assembly work is simple and fast, which greatly improves the user experience.

[0048] As shown in Figures 8 to 10, the first locking structure 15 includes an escape notch 151 and a first engaging protrusion 152 formed on the edge of the mounting opening 12. The first engaging protrusion 152 is disposed adjacent to the escape notch 151. As shown in Figures 11 and 12, the second locking structure 23 includes a second engaging protrusion 231. The second engaging protrusion 231 forms an engaging groove 232 with the edge of the cover 21. When the cover 21 of the filter assembly 20 is closed over the mounting opening 12, the second engaging protrusion 231 is aligned with the escape notch 151 and passed through the escape notch 151. Then, the cover 21 is rotated in the positive direction S around the central axis of the cover 21 so that the first engaging protrusion 152 engages with the engaging groove 232. In this way, the first locking protrusion 152 is locked in the locking groove 232, that is, the cover body 21 of the filter assembly 20 and the dust box body 10 are locked to each other by the first locking structure 15 and the second locking structure 23, and the filter assembly 20 is quickly installed on the dust box body 10.

[0049] To more quickly install the filter assembly 20 on the dust box body 10, as shown in Figures 9 and 10, at least one first locking structure 15 further includes a stop protrusion 153. The stop protrusion 153 is positioned adjacent to the corresponding escape notch 151, and the stop protrusion 153 and the corresponding first engaging protrusion 152 are located on either side of the escape notch 151. The stop protrusion 153 is used to prevent the second engaging protrusion 231 from rotating toward the stop protrusion 153 after the second engaging protrusion 231 passes through the escape notch 151. In other words, the stop protrusion 153 blocks the second engaging protrusion 231 from rotating toward the stop protrusion 153. This prevents the cover 21 from rotating in the forward direction S during installation of the filter assembly 20, preventing the cover 21 from being installed simply by rotating it. This further improves installation efficiency and provides a more accurate installation result.

[0050] As shown in Figure 10 , the inner wall of the dust collection chamber 11 is provided with a limiting groove 16, located below the first engaging protrusion 152. Accordingly, as shown in Figure 12 , the second engaging protrusion 231 is provided with a limiting protrusion 233. When the first engaging protrusion 152 engages the engaging groove 232, the limiting protrusion 233 engages within the limiting groove 16. Thus, the engagement of the limiting protrusion 233 with the limiting groove 16 prevents the first locking structure 15 and the second locking structure 23 from being arbitrarily disengaged or unlocked, thereby ensuring the assembly stability between the filter assembly 20 and the dust box body 10.

[0051] In the embodiment of the present application, as shown in FIG12 , the second engaging protrusion 231 defines an overhead space 234 opposite the limiting protrusion 233. Due to the overhead space 234, when the limiting protrusion 233 is subjected to a force or obstruction, the second engaging protrusion 231 elastically deforms with the aid of the overhead space 234, allowing the limiting protrusion 233 to use the overhead space 234 for evasive movement. Furthermore, when the limiting protrusion 233 reaches the limiting groove 16, the elastic force of the second engaging protrusion 231 further enhances the restraining force between the limiting protrusion 233 and the limiting groove 16, thereby preventing the first locking structure 15 and the second locking structure 23 from arbitrarily disengaging and unlocking, thereby better ensuring the assembly stability between the filter assembly 20 and the dust box body 10.

[0052] As shown in Figures 8 to 11, the cover 21 includes a main body 211 and a clamping portion 212. The clamping portion 212 is detachably connected to the main body 211, and the filter 22 is clamped and fixed to the main body 211 by the clamping portion 212. Thus, after removing the filter assembly 20 from the dust box body 10, the filter 22 can be replaced by simply removing the clamping portion 212 from the main body 211, making the removal and replacement of the filter 22 simple, convenient, and quick.

[0053] Specifically, as shown in Figures 11 and 12, the main body 211 is provided with a plurality of spaced first connecting plates 2111 on the side facing the filter 22. As shown in Figure 11, the clamping portion 212 includes a plurality of spaced second connecting plates 2121, with the plurality of first connecting plates 2111 and the plurality of second connecting plates 2121 being provided in a one-to-one correspondence. Furthermore, as shown in Figures 11 and 12, a clamping head 2112 is provided at the end of one of the first connecting plates 2111 and the second connecting plates 2121, and a clamping interface 2122 is provided at the end of the other of the first connecting plates 2111 and the second connecting plates 2121. The clamping head 2112 is plugged into the clamping interface 2122. In the embodiment of the present application, the clamping head 2112 is provided at the end of the first connecting plate 2111, and the clamping interface 2122 is provided at the end of the second connecting plate 2121. That is to say, the main body 211 and the clamping portion 212 can be connected by simply plugging the clamping head 2112 and the clamping interface 2122 together, thereby clamping the filter screen 22. The connection process is simple and quick.

[0054] In the embodiment of the present application, the filter screen 22 is cylindrical.
