[0044] As Figures 1 to 7As shown, the cleaning device 300 provided by the embodiments 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 is formed with an assembly space, and the body assembly 310 is provided with an exhaust port 312 communicating with the outside. The dust collection assembly 320 includes an inner shell 321 and a dust collection box 100 mounted to the inner shell 321, the inner shell 321 is fixedly mounted to the body assembly 310 and located in the assembly space, and the inner shell 321 is provided with a first air inlet and a first air outlet 3212, both of which communicate with the dust collection box 100. The fan 330 is fixedly mounted to the body assembly 310 and located in the assembly space, and the fan 330 has an airflow inlet 331 and an airflow outlet 332, the airflow inlet 331 is in communication with the first air outlet 3212, and a first elastic member 351 is arranged between the periphery of the airflow inlet 331 and the periphery of the first air outlet 3212, the first elastic member 351 is clamped between the periphery of the airflow inlet 331 and the periphery of the first air outlet 3212, so that the first elastic member 351 is clamped and elastically deformed to realize the sealing arrangement between the airflow inlet 331 and the first air outlet 3212. The air duct assembly 340 is located in the assembly space, and 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 communicates with the airflow outlet 332, the outlet end 342 is connected to the body assembly 310 through a second elastic member 352, and the outlet end 342 extends to the inner wall of the assembly space and communicates with the exhaust port 312.

[0045] The fan 330 of the cleaning device of the present application drives the airflow to flow, thereby carrying the debris and dust on the ground into the interior of the dust collection box 100 of the dust collection assembly 320, and the debris and dust are trapped 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. The periphery of the airflow inlet 331 of the fan 330 and the periphery of the first air outlet 3212 are provided with the first elastic member 351, and the outlet end 342 of the air duct assembly 340 is connected to the body assembly 310 through the second elastic member 352, and the inlet end 341 of the air duct assembly 340 is connected to the fan 330 and communicates with the airflow outlet 332 of the fan 330, that is, the front end and the rear end of the whole assembly of the fan 330 and the air duct assembly 340 are buffered and damped by the first elastic member 351 and the second elastic member 352 respectively. Therefore, during the operation of the fan 330, the vibration generated by the fan 330 is buffered and damped when transmitted to the first elastic member 351 and the second elastic member 352, reducing the energy of subsequent vibration transmission, significantly reducing the influence of the vibration generated by the fan 330 on the whole cleaning device, thereby realizing the effect of noise reduction and silence of the cleaning device. Moreover, the vibration is reduced to be transmitted to the body assembly 310, thereby reducing the risk of loosening of the connection structure in the cleaning device.

[0046] As shown in Figures 2 to 4 , the second elastic member 352 is fixedly sleeved on the outlet end 342. As shown in Figure 3 , the body assembly 310 is provided with two opposite insertion columns 313, and each of the two insertion columns 313 is provided with a vertical slot. The opposite side edge regions of the elastic member are respectively inserted into the vertical slots of the two insertion columns 313. Through the insertion of the vertical slots of the insertion columns 313 and the side edge regions of the second elastic member 352, after the second elastic member 352 is firmly sleeved on the outlet end 342 of the air duct assembly 340, the second elastic member 352 can be conveniently and quickly installed on the insertion columns 313, and the installation efficiency is high, and subsequent operations such as disassembly, cleaning and maintenance, replacement, etc. of the air duct assembly 340 are facilitated.

[0047] As shown in Figure 2 and Figure 4 , the body assembly 310 includes a rack 314 and a face cover 315, and the face cover 315 covers the rack 314 to form an assembly space, and the exhaust port 312 is formed in the face cover 315. When the face cover 315 covers the rack 314, the second elastic member 352 is sealed and abuts against the peripheral side wall of the exhaust port 312 of the face cover 315, thereby achieving sealing between the outlet end 342 and the exhaust port 312. In the embodiment of the present application, the second elastic member 352 can have a pressing force with the inner wall surface of the face cover 315, so that the second elastic member 352 is slightly elastically deformed, thereby achieving sealing between the outlet end 342 and the exhaust port 312. Alternatively, the second elastic member 352 and the inner wall surface of the face cover 315 are sealed and injected to achieve sealing, and after the sealing injection is cured, it can also be hot melted or directly torn off, thereby facilitating the separation between the face cover 315 and the second elastic member 352.

[0048] As shown in Figure 6 , the air outlet 332 includes opposite first and second outlets 3321 and 3322. As shown in Figures 3 to 7As shown, the air duct assembly 340 includes a first air duct pipe 343 and a second air duct pipe 344. The inlet end 341 of the first air duct pipe 343 is in communication with the first outlet 3321, and the inlet end 341 of the second air duct pipe 344 is in communication with the second outlet 3322. The outlet end 342 of the first air duct pipe 343 and the outlet end 342 of the second air duct pipe 344 are both connected to the body assembly 310 through the second elastic member 352. In the embodiment of the present application, the two air ducts of the opposite first air duct pipe 343 and the second air duct pipe 344 are designed to divide the airflow blown by the fan 330 into two paths along the first air duct pipe 343 and the second air duct pipe 344. The airflow at the airflow outlet 332 of the fan 330 is blown into the first air duct pipe 343 and the second air duct pipe 344 in a tangential direction. This can effectively reduce the resistance along the path of the airflow flowing in the air duct assembly 340, effectively reduce the vortex generated by the airflow flowing, and thus achieve a significant noise reduction effect.

[0049] In order to reduce the noise caused by airflow, therefore, as shown in Figure 6 and Figure 7 The cleaning device 300 further includes a first sound-absorbing cotton 353 attached to the inner wall of the passage of the air duct assembly 340. When the airflow flows in the first air duct pipe 343 and the second air duct pipe 344, the airflow hits the first sound-absorbing cotton 353, and the first sound-absorbing cotton 353 can effectively absorb the impact energy of the airflow, thereby achieving noise reduction.

[0050] In order to further reduce the noise caused by airflow, therefore, as shown in Figure 6 and Figure 7 The cleaning device 300 further includes a second sound-absorbing cotton 354 attached to the inner wall of the airflow outlet 332 of the fan 330, so that the airflow blown by the fan 330 to the airflow outlet 332 blows towards the second sound-absorbing cotton 354. When the airflow is blown by the fan 330 to the airflow outlet 332, the airflow will hit the second sound-absorbing cotton 354, and the second sound-absorbing cotton 354 can absorb the impact energy of the airflow at this time, thereby achieving noise reduction.

[0051] As shown in Figures 8 to 12As shown, the dust collecting box 100 provided by the embodiment of the present application comprises a dust box body 10 and a filter screen assembly 20. The dust box body 10 is formed with a dust collecting chamber 11, and is provided with a mounting port 12, a second air inlet 13 and a second air outlet 14, which are all in communication with the dust collecting chamber 11. The edge of the mounting port 12 is provided with a plurality of first locking structures 15 at intervals. The filter screen assembly 20 comprises a cover body 21 and a filter screen 22, the filter screen 22 is connected to the cover body 21, the cover body 21 covers the mounting port 12, and the filter screen 22 extends into the dust collecting chamber 11 to separate the second air inlet 13 and the second air outlet 14. The airflow flows from the second air inlet 13 to the filter screen 22, so that the debris and dust carried by the airflow are intercepted by the filter screen 22, and then the clean airflow passing through the filter screen 22 is blown out from the second air outlet 14. The cover body 21 is provided with a plurality of second locking structures 23 at intervals, and the plurality of second locking structures 23 are arranged one by one corresponding to the plurality of first locking structures 15. When the cover body 21 covers the mounting port 12, the cover body 21 is rotated along the positive direction S around the central axis of the cover body 21 to lock the second locking structures 23 and the first locking structures 15; the cover body 21 is rotated in the reverse direction around the central axis of the cover body 21 to unlock the second locking structures 23 and the first locking structures 15.

[0052] The dust collecting box 100 provided by the present application is assembled to the cleaning device 300 to intercept the debris and dust carried by the airflow inhaled by the cleaning device 300, so as to achieve the purpose of dust cleaning. In the dust collecting box 100, when the cover body 21 of the filter screen assembly 20 covers the mounting port 12, the cover body 21 is rotated along the positive direction S around the central axis of the cover body 21 to lock the second locking structures 23 and the first locking structures 15, so as to simply and quickly install the filter screen assembly 20 to the dust box body 10. On the other hand, when it is desired to disassemble the filter screen assembly 20 from the dust box body 10, the cover body 21 is rotated in the reverse direction around the central axis of the cover body 21 to unlock the second locking structures 23 and the first locking structures 15, so as to disassemble the filter screen assembly 20 from the dust box body 10. The disassembly process is simple and fast. Compared with the current cleaning robot, when the dust collecting box 100 of the cleaning device 300 provided by the present application is disassembled, only one rotation and one lifting two-step action are required to disassemble the filter screen assembly 20 from the dust box body 10. There is no complicated step of disassembling other components. The disassembly work is simple and fast, and the user's experience is greatly improved.

[0053] As shown in Figures 8 to 10 The first locking structure 15 comprises a avoiding gap 151 opened in the edge of the mounting port 12 and a first clamping protrusion 152, and the first clamping protrusion 152 is arranged adjacent to the avoiding gap 151. Figure 11 and Figure 12As shown, the second locking structure 23 comprises a second clamping protrusion 231, and the second clamping protrusion 231 forms a clamping groove 232 with the edge of the cover 21. When the cover 21 of the filter assembly 20 is covered on the installation opening 12, the second clamping protrusion 231 is aligned with the avoiding gap 151, and the second clamping protrusion 231 passes through the avoiding gap 151, and then the cover 21 is rotated along the positive direction S around the central axis of the cover 21, so that the first clamping protrusion 152 is clamped into the clamping groove 232. In this way, the first clamping protrusion 152 is locked in the clamping groove 232, that is, the cover 21 of the filter assembly 20 and the dust box body 10 are locked by the first locking structure 15 and the second locking structure 23, and the installation of the filter assembly 20 on the dust box body 10 is completed quickly.

[0054] In order to complete the installation of the filter assembly 20 on the dust box body 10 more quickly, therefore, as shown in Figure 9 and Figure 10 As shown, the at least one first locking structure 15 further comprises a stop protrusion 153, the stop protrusion 153 is arranged adjacent to the corresponding avoiding gap 151, and the stop protrusion 153 is located on both sides of the corresponding first clamping protrusion 152 and the avoiding gap 151, respectively, and the stop protrusion 153 is used to stop the second clamping protrusion 231 from rotating towards the stop protrusion 153 after the second clamping protrusion 231 passes through the avoiding gap 151. That is, the second clamping protrusion 231 is prevented from rotating by the stop protrusion 153, so that the cover 21 can only be rotated in the positive direction S during the installation of the filter assembly 20, and there is no condition that the cover 21 can be randomly rotated to complete the installation. In this way, the installation efficiency is further improved, and the installation effect is more accurate.

[0055] As shown in Figure 10 The inner wall of the dust collection chamber 11 is provided with a limiting groove 16, and the limiting groove 16 is located below the first clamping protrusion 152. Correspondingly, as shown in Figure 12 The second clamping protrusion 231 is provided with a limiting protrusion 233. When the first clamping protrusion 152 is clamped into the clamping groove 232, the limiting protrusion 233 is clamped into the limiting groove 16. In this way, by cooperating the limiting protrusion 233 with the limiting groove 16, the first locking structure 15 and the second locking structure 23 are prevented from being randomly unlocked, and the assembly stability between the filter assembly 20 and the dust box body 10 is ensured.

[0056] In the embodiment of the present application, as shown in Figure 12As shown, the second clamping protrusion 231 is provided with an overhang space 234 opposite to the limiting protrusion 233. When the limiting protrusion 233 is subjected to force or obstruction, the second clamping protrusion 231 is elastically deformed by the overhang space 234, so that the limiting protrusion 233 can be buffered by the overhang space 234. When the limiting protrusion 233 reaches the limiting groove 16, the limiting ability between the limiting protrusion 233 and the limiting groove 16 is sufficient under the elastic deformation of the second clamping protrusion 231, so as to prevent the first and second locking structures 15 and 23 from being separated at will, and better ensure the assembly stability between the filter screen assembly 20 and the dust box body 10.

[0057] As shown in the drawings, Figures 8 to 11 The cover 21 comprises a body portion 211 and a clamping portion 212, the clamping portion 212 is detachably connected to the body portion 211, and the filter screen 22 is clamped and fixed on the body portion 211 through the clamping portion 212. In this way, after the filter screen assembly 20 is detached from the dust box body 10, the clamping portion 212 is only needed to be detached from the body portion 211, and the filter screen 22 can be replaced, so that the replacement of the filter screen 22 is simple, convenient and fast.

[0058] Specifically, as shown in the drawings, Figure 11 and Figure 12 The body portion 211 is provided with a plurality of first connecting plates 2111 on the side facing the filter screen 22. As shown in the drawings, Figure 11 The clamping portion 212 comprises a plurality of second connecting plates 2121, and the plurality of first connecting plates 2111 and the plurality of second connecting plates 2121 are one-to-one corresponding. As shown in the drawings, Figure 11 and Figure 12 One of the first connecting plate 2111 and the second connecting plate 2121 is provided with a clamping head 2112, and the other one is provided with a clamping hole 2122, and the clamping head 2112 is inserted into the clamping hole 2122. In the embodiment of the present application, the end of the first connecting plate 2111 is provided with the clamping head 2112, and the end of the second connecting plate 2121 is provided with the clamping hole 2122. That is, the body portion 211 and the clamping portion 212 can be connected by directly inserting the clamping head 2112 and the clamping hole 2122 together, so as to clamp the filter screen 22, and the connection process is simple and fast.

[0059] In the embodiment of the present application, the filter screen 22 is cylindrical. As shown in the drawings, Figure 11As shown, the clamping portion 212 further comprises a ring-shaped receiving member 2123, and a plurality of second connecting plates 2121 are arranged on the ring-shaped receiving member. After the body portion 211 is connected with the clamping portion 212, one end of the filter screen 22 along the axial direction abuts against the body portion 211, and the other end abuts against the ring-shaped receiving member 2123, that is, the body portion 211 and the ring-shaped receiving member 2123 of the clamping portion 212 jointly clamp the filter screen 22.
