After the slider 244 slides in place in the track 243, each third sub-connecting portion 2471 is clamped with each first sub-connecting portion 2461, and each fourth sub-connecting portion 2472 is clamped with each second sub-connecting portion 2462, so as to ensure the stability of the filter assembly 242 assembled on the cassette body 241.

In one embodiment, a second gap 2414 is formed at the top of the receiving cavity 2412, and the top surface of the dust box 20 is formed on the assembly 2422. First anti-disengaging part 248 is arranged in accommodating cavity 2412, second anti-disengaging part 249 is arranged on assembly part 2422, and second anti-disengaging part 249 is in limit fit with first anti-disengaging part 248 to limit assembly part 2422 from being disengaged from accommodating cavity 2412 through second gap 2414. By arranging the first retaining portion 248 and the second retaining portion 249 to be matched in a limiting manner, the filter assembly 242 is prevented from being released from the accommodating cavity 2412 from the second gap 2414 when the filter assembly 242 receives an upward acting force after the filter assembly 242 is assembled on the box body 241.

One of the first retaining portion 248 and the second retaining portion 249 is a limiting groove, the limiting groove has an opening at one end of the assembly part 2422 in the assembly direction of the accommodating portion 2411, and the other of the first retaining portion 248 and the second retaining portion 249 is a plug-in portion. The width of the limiting groove is gradually reduced from one end with the opening to the end far away from the opening, the insertion part is inserted into the limiting groove from the opening, and the limiting groove is gradually matched with the limiting groove from the end with the opening to the end far away from the opening.

Through the above arrangement, when the slider 244 slides into the track 243, the insertion portion is gradually inserted into the end with the smaller width from the end with the larger width of the limiting groove, so that the insertion portion and the limiting groove are ensured to be matched more and more tightly, and the filter assembly 242 is further prevented from being separated from the accommodating cavity 2412 from the second gap 2414.

In one embodiment, the assembly 2422 includes a first plate 24221, a second plate 24222 and a third plate 24223 (see fig. 11 and 12), the first plate 24221 is connected to and perpendicular to the second plate 24222, two ends of the third plate 24223 are respectively connected to the first plate 24221 and the second plate 24222, and the first plate 24221, the second plate 24222 and the third plate 24223 define an assembly cavity 2423 communicating with the dust collection cavity 21. The top surface of the dust collecting box 20 is formed on the first plate 24221, the third clamping part 2471 is connected with the first plate 24221, the second plate 24222 forms part of the side surface of the dust collecting box 20, the fourth clamping part 2472 is connected with the second plate 24222, the first plate 24221 or the second plate 24222 is provided with an air outlet 23 communicated with the assembling cavity 2423, the third plate 24223 is positioned in the accommodating cavity 2412, the filter element 2421 is arranged in the assembling cavity 2423, and the plane of the filter element 2421 is parallel to the plane of the third plate 24223. It should be understood that in other embodiments, the manner in which fitting 2422 is disposed is not limited thereto, nor is it limited thereby.

Specifically, the third plate 24223 has a grid-like shape, and facilitates the flow of air from the dust collection chamber 21 into the fitting chamber 2423 while serving to support the filter member 2421.

Referring to fig. 13, in one embodiment, the exterior surface of the assembly 2422 is further provided with a depression 24224 for facilitating manual grasping thereof, such that the filter element 242 may be manipulated by simply grasping the depression 24224 when it is desired to disassemble the filter element 242.

In one embodiment, the dust collecting box 20 further includes a trigger 25 (see fig. 3 and 10), the outer surface of the assembly part 2422 or the box body 241 has an assembly part 26, the trigger 25 is assembled on the assembly part 26, the main body 10 of the sweeping robot 100 is provided with a triggered part, and the triggered part judges whether the dust collecting box 20 is assembled or not through the trigger 25, so as to determine whether the sweeping robot 100 has a normal working condition or not. When the triggered piece does not sense the trigger piece 25, the sweeping robot 100 judges that the dust collecting box 20 is not assembled, and at this time, the sweeping robot 100 does not have a condition of normal operation; if the trigger 25 is sensed by the trigger, the sweeping robot 100 determines that the dust collecting box 20 is assembled, and the sweeping robot 100 has a normal working condition.

By providing the assembling portion 26 on the outer surface of the assembly part 2422 or the case body 241, the trigger 25 is assembled on the assembling portion 26, since the filter element 2421 is assembled in the assembling cavity 2423 of the assembly part 2422, that is, the filter element 2421 is positioned in the assembly part 2422, when the trigger 25 needs to be replaced, the filter element 2421 does not need to be removed (since the filter element 2421 is generally adhered to the assembly part 2422 by glue, if the filter element 2421 is removed, the filter element 2421 is damaged or even unusable), and the replacement of the trigger 25 is facilitated.

It should be noted that, the outer surface of the fitting part 2422 refers to: the outer surface of the filter assembly 242, when not yet mounted to the cartridge 241, tends to be partially obscured by the cartridge 241 when the fitting 2422 is mounted to the cartridge 241.

Specifically, the trigger 25 is a magnet. When the triggered piece does not sense the magnet, the sweeping robot 100 judges that the dust collecting box 20 is not assembled, and at this time, the sweeping robot 100 does not have a normal working condition; if the magnet is sensed by the trigger, the cleaning robot 100 determines that the dust collecting box 20 is assembled, and the cleaning robot 100 has a normal working condition.

In one embodiment, when the filter element 242 is mounted to the cartridge 241, the mounting portion 26 is hidden between the mounting member 2422 and the cartridge 241, and the trigger 25 mounted to the mounting portion 26 is hidden between the mounting member 2422 and the cartridge 241. It should be appreciated that in another embodiment, when the filter assembly 242 is not mounted on the case 241, the mounting portion 26 is exposed to the outside, and the trigger 25 is also exposed to the outside.

Specifically, the mounting portion 26 is a mounting groove formed on the outer surface of the mounting member 2422 or the case 241, and the trigger 25 is received in the mounting groove. Of course, in other embodiments, the mounting portion 26 may also be a mounting hole provided on an outer surface of the mounting member 2422 or on the box body 241, which is not limited herein.

In one embodiment, the mounting portion 26 is disposed on one side of the assembly 2422 or the cassette 241 having the track 243 or the slider 244, and when the filter element 242 is mounted on the cassette 241 by the slider 244 and the track 243, the mounting portion 26 and the trigger 25 are hidden between the assembly 2422 and the cassette 241. With continued reference to fig. 11, assembly 2422 further includes a connecting portion, and second retaining portion 249 is connected to second plate 24222 of assembly 2422 via the connecting portion, and the assembly slot is disposed on the connecting portion. It should be understood that in other embodiments, the location of the mounting slot is not limited.

Referring to fig. 14 and 15, in one embodiment, the dust collecting box 20 further includes a handle 27, and the handle 27 is pivotally connected to the box 241 and can be switched between a vertically disposed lifting position and a horizontally disposed limiting position relative to the box 241. The surface of the handle 27 departing from the box 241 is provided with a first limiting part 271, the housing 11 of the sweeping robot 100 is provided with a second limiting part 111, and when the handle 27 is at the limiting position, the first limiting part 271 can be in limiting fit with the second limiting part 111 to limit the position of the dust collecting box 20, so as to ensure that the dust collecting box 20 is assembled in place (see fig. 16).

By arranging the first limiting part 271 on the surface of the handle 27 departing from the box 241, the volume occupied by the limiting mechanism arranged on the handle 27 is reduced, so that the volume occupied by other structures of the sweeping robot 100 can be correspondingly increased, and unnecessary waste of space is reduced.

Further, the first position-limiting portion 271 is a protruding point protruding from the surface of the handle 27, and the second position-limiting portion 111 is a groove matching with the protruding point. Of course, in other embodiments, the first limiting portion 271 may be a groove recessed in the surface of the handle 27, and the second limiting portion 111 may be a bump matching with the first limiting portion 271, which is not limited herein.

When the first limiting part 271 and the second limiting part 111 are configured to have a structure in which the protrusions and the grooves are matched, the dust collecting box 20 is assembled on the main body 10 of the sweeping robot 100 by the handle 27, and then the handle 27 is operated to switch from the lifting position to the limiting position, and the protrusions and the grooves are matched to limit the dust collecting box 20 on the main body 10 of the sweeping robot 100.

Further, the two ends of the handle 27 are provided with the first limiting portions 271, and the first limiting portions 271 located at the two ends of the handle 27 are symmetrically arranged with respect to the central line of the handle 27 (to distinguish from the first central line X1 and the second central line X2, the central line of the handle 27 is defined as a third central line), so that the stability of limiting is ensured.

Referring to fig. 17 to 19, the end of the handle 27 forms an arc-shaped first guide mating surface 272, the housing 11 of the sweeping robot 100 forms a second guide mating surface 112, and during the process of switching the lifting position and the limiting position of the handle 27, the first guide mating surface 272 is in guide mating with the second guide mating surface 112 on the main body 10 of the sweeping robot 100, so that the handle 27 can be conveniently switched between the lifting position and the limiting position.

Further, a first rotating matching part 273 is further arranged on the handle 27, a second rotating matching part 113 is arranged on the shell 11 of the sweeping robot 100, and the first rotating matching part 273 is in rotating matching with the second rotating matching part 113 in the process of switching the lifting position and the limiting position of the handle 27. And when the handle 27 is at the limit position, the first rotation matching part 273 is matched with the second rotation matching part 113 in a limit mode so as to limit the handle 27 to rotate continuously from the lifting position to the direction of the limit position.

With the above arrangement, the first rotation engagement portion 273 and the second rotation engagement portion 273 facilitate the switching of the handle 27 between the lifting position and the limiting position. When the handle 27 is located at the limiting position, the first rotating matching part 273 and the second rotating matching part 113 are in limiting matching to limit the handle 27 to continue rotating from the lifting position towards the direction of the limiting position, and meanwhile, the first limiting part 271 and the second limiting part 111 are in limiting matching to limit the handle 27 in a dual-action manner, so that the stability of limiting the dust collection box 20 is ensured.

Specifically, the first rotation matching portion 273 extends along a direction perpendicular to the extension direction of the handle 27 and is disposed on the handle 27, and the first rotation matching portion 273 is an arc-shaped groove or a semi-circular block shape having an opening.

In this embodiment, the semicircular block shape is not only a half of the circular block, but is divided into semicircular block shapes as long as the sectional shape includes an arc and a straight line connecting each other.

In one embodiment, the first rotating fitting portion 273 is provided in a shape of a half circular block, and the second rotating fitting portion 113 is provided in a shape of a circular arc groove having an opening. Of course, in another embodiment, the first rotation matching portion 273 may be a circular groove with an opening, and the second rotation matching portion 113 may be a semi-circular block, which is not limited herein.

Another embodiment of the present invention further provides a dust collecting box 20 included in the floor sweeping robot 100, wherein the dust collecting box 20 includes a box body 241, a filtering component 242 and a triggering component 25. Filter element 242 includes a fitting 2422 and a filter element 2421 mounted on fitting 2422; the assembly part 2422 is detachably assembled to the case body 241 and is provided with an air outlet 23. The assembly part 2422 is provided with an airflow channel for communicating the dust collection cavity 21 with the air outlet 23; the filter 2421 is located in the airflow path of the airflow from the dust collecting chamber 21 to the air outlet 23. The trigger 25 is provided independently of the filter element 2421, and the trigger 25 is mounted to the cartridge body 241 or to the fitting 2422 outside the airflow path.

The embodiment of the utility model provides a dust collection box 20, because trigger 25 is independent of filtering piece 2421 and sets up, and trigger 25 assembles on box body 241 or outside the airflow channel of assembly part 2422, when needing to be changed trigger 25, then no longer need take off filtering piece 2421 (because filter 2421 generally pastes on assembly part 2422 through gluing, if will filter 2421 and take off, then can lead to filtering piece 2421 to damage or even unusable), trigger 25 changes the convenience.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
