[0054] It should be noted that when an element is referred to as "fixed to" or "provided on" another element, it can be directly on another element or there can be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element. The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for illustrative purposes and are not the only embodiment.

[0055] As described in the background, the conventional dust collecting box has the problem of inconvenient disassembly of the filter. The present inventors have found that the root cause of the above problem is that when disassembling the filter, the cover must be removed first before the filter can be removed; when the filter is cleaned, the filter is first assembled on the box body of the dust collecting box, and then the cover with the air outlet is assembled. The above arrangement causes the filter to be inconvenient to disassemble.

[0056] Referring to Figure 1An embodiment of the present application provides a sweeping robot 100, which comprises a main body 10 and a dust collecting box 20 arranged on the main body 10 and used for collecting dust. When the dust in the dust collecting box 20 reaches a certain capacity, the user can take down the dust collecting box 20 from the main body 10 to pour out the dust, and then assemble the dust collecting box 20 on the main body 10 again to collect dust.

[0057] Please refer to Figure 2 The main body 10 comprises a shell 11, a rolling brush assembly (not shown in the figure) and an air duct assembly 12 arranged on the shell 11, the air duct assembly 12 comprises an air duct 121 and a power element 122, and the rolling brush assembly and the air duct assembly 12 are arranged on opposite sides of the dust collecting box 20 respectively. Referring to Figure 2 , the air duct assembly 12 is located at the lower left side of the dust collecting box 20 in Figure 2 , and the rolling brush assembly is located at the upper right side of the dust collecting box 20 in Figure 2 .

[0058] Specifically, the dust collecting box 20 is provided with a dust collecting cavity 21 (see Figure 3 ), and the dust collecting box 20 is provided with an air inlet 22 and an air outlet 23 (see Figure 4 ) both of which are in communication with the dust collecting cavity 21, the rolling brush assembly is in communication with the air inlet 22, and the air duct assembly 12 is in communication with the air outlet 23. More specifically, the power element 122 is connected with the dust collecting box 20 through the air duct 121, and the air duct 121 is in communication with the air outlet 23, and the power element 122 is used to provide power for the airflow to flow from the rolling brush assembly to the dust collecting box 20 and from the dust collecting box 20 to the air duct 121.

[0059] When the sweeping robot 100 works, the power element 122 is started, the airflow carrying dust from the outside enters the dust collecting box 20 from the rolling brush assembly, the dust is retained in the dust collecting box 20, and the clean gas flows from the dust collecting box 20 to the air duct 121 and is discharged to the outside after passing through the power element 122. Specifically, the rolling brush assembly comprises a roller body, a brush body and a rolling brush driving element, the roller body is connected with the rolling brush driving element, and the brush body is arranged on the surface of the roller body. The power element 122 is a fan, which comprises a volute, a motor and a fan blade, the volute is in communication with the air duct 121, and the motor and the fan blade are both arranged in the volute. The rolling brush driving element drives the roller body to rotate around its own axis, and in turn drives the brush body on the surface of the roller body to rotate, and the dust and other garbage on the ground are brought up by the rotating brush body through the contact between the rotating brush body and the ground. At the same time, the motor drives the fan blade to rotate in the volute, so as to generate flowing airflow, the flowing airflow carrying the dust brought up by the rolling brush assembly enters the dust collecting box 20, the dust is retained in the dust collecting box 20, the clean airflow enters the air duct 121 from the dust collecting box 20, and finally enters the volute from the air duct 121 and is discharged.

[0060] Please refer to Figure 2The sweeping robot 100 further comprises a first power supply 13, which is mounted on the housing 11, and the rolling brush assembly and the air duct assembly 12 are electrically connected with the first power supply 13, and the first power supply 13 is used to provide the rolling brush assembly and the air duct assembly 12 with the power required by the rolling brush assembly and the air duct assembly 12.

[0061] Referring to Figure 5 In the embodiment of the present application, the dust collecting box 20 comprises a body 24, the dust collecting cavity 21 is arranged in the body 24, and the air inlet 22 and the air outlet 23 are arranged on the body 24. The body 24 has a circumferential direction relative to the longitudinal direction, and a first side of the body 24 in the circumferential direction is provided with the air outlet 23 and a first mounting area independent of the air outlet 23. Referring to Figure 6 The longitudinal direction X of the body 24 (the longitudinal direction X of the dust collecting box 20 is also the longitudinal direction X of the body 24) is a direction from the upper left to the lower right in Figure 6 , or a direction from the lower right to the upper left.

[0062] That is, when the body 24 is placed on a horizontal plane, the body 24 has a top surface and a bottom surface arranged oppositely, the connecting direction of the top surface and the bottom surface is the second direction Z, the first direction Y is perpendicular to the longitudinal direction X and the second direction Z, and the air outlet 23 is arranged on the first side in the first direction.

[0063] The length of the body 24 in the longitudinal direction X is a first length L1, and the length of the air outlet 23 in the longitudinal direction X of the body 24 is a second length L2 (referring to Figure 6 and Figure 7 ), and the ratio of the second length L2 to the first length L1 is 2 / 5-2 / 3. In the longitudinal direction X, the first mounting area is located at least one side of the air outlet 23, and the first power supply 13 is mounted on the first mounting area.

[0064] Through the above arrangement, in the longitudinal direction X of the body 24, the air outlet 23 occupies a smaller length of the body 24, so that the first mounting area can be reserved on the first side of the body 24 where the air outlet 23 is arranged to facilitate the mounting of the first power supply 13, that is, the first power supply 13 and the air duct assembly 12 are arranged on the same side of the body 24 in the first direction Y, that is, when the sweeping robot 100 is placed on the ground, the first power supply 13 is located on the left side and / or the right side of the air duct assembly 12 in the longitudinal direction X of the body 24 (referring to the direction shown in Figure 2 ), so as to avoid arranging the power supply and the air duct assembly 12 in front and back (in the first direction Y, the power supply and the air duct assembly 12 are arranged on opposite sides of the dust collecting box 20), thereby improving the space utilization of the sweeping robot 100, and reducing the volume of the sweeping robot 100.

[0065] In one embodiment, a first virtual plane is defined by a first virtual straight line parallel to the first direction Y and a second virtual straight line parallel to the second direction Z. The orthogonal projection of the first power supply 13 towards the first virtual plane at least partially overlaps with the orthogonal projection of the air duct assembly 12 towards the first virtual plane. That is, the first power supply 13 is at least partially opposite to the air duct assembly 12 in the longitudinal direction X of the body 24, so that the volume occupied by the first power supply 13 can be reduced, and the space utilization of the robotic vacuum cleaner 100 can be improved.

[0066] Specifically, the orthogonal projection of the first power supply 13 towards the first virtual plane is located within the range of the orthogonal projection of the air duct assembly 12 towards the first virtual plane, that is, the first power supply 13 is completely opposite to the air duct 121. More specifically, the orthogonal projection of the first power supply 13 towards the first virtual plane is located within the range of the orthogonal projection of the air duct 121 towards the first virtual plane. It should be understood that in other embodiments, the orthogonal projection of the first power supply 13 towards the first virtual plane is located within the range of the orthogonal projection of the air duct 121 and the power member 122 towards the first virtual plane, which is also not limited herein.

[0067] Referring to Figure 8 In one embodiment, the first side surface has a first middle line X1 extending along the second direction Z, the air outlet 23 is located on one side of the first middle line X1, and the first mounting area is located on the other side of the first middle line X1. At this time, the air outlet 23 is located on the left side or the right side of the first side surface, and the first power supply 13 can be arranged on one side of the air duct assembly 12 in the longitudinal direction X of the body 24. Referring to Figure 7 Specifically, the first side surface has a first side edge a and a second side edge b extending along the second direction Z, the air outlet 23 has a third side edge c and a fourth side edge d extending along the second direction Z, and the third side edge c is arranged close to the first side edge a relative to the fourth side edge d. The distance between the first side edge a and the third side edge c in the longitudinal direction X is a first distance L3, the distance between the fourth side edge d and the second side edge b in the longitudinal direction X is a second distance L4, and the length of the shorter one of the first distance L3 and the second distance L4 is 20-40 mm.

[0068] It should be understood that in another embodiment, the first middle line X1 can also pass through the air outlet 23, at this time, the air outlet 23 is located at the middle position of the first side surface, and the first mounting area is located on both sides of the air outlet 23, and the first power supply 13 is located on both sides of the air duct assembly 12 in the longitudinal direction X of the body 24.

[0069] Referring to Figure 8Further, the first side has a second center line X2 extending along the longitudinal direction X, and the air outlet 23 is located above the second center line X2. The side of the body 24 where the air outlet 23 is located has a second mounting area. In the second direction Z, the second mounting area is located below the second center line X2. In this case, the sweeping robot 100 is provided with a second power supply, and the second power supply is arranged on the above-mentioned second mounting area of the air duct 121, so as to increase the capacity of the entire power supply and facilitate power supply of the sweeping robot 100.

[0070] The first power supply 13 and the air duct assembly 12 are located in the plane of the body 24 of the dust collecting box 20 in the orthographic projection, so as to prevent the first power supply 13 and the air duct assembly 12 from being too large in size and improve the space utilization of the sweeping robot 100.

[0071] In an embodiment, the first power supply 13 is integrally arranged with the second power supply. It should be understood that, in other embodiments, the first power supply 13 can also be arranged separately from the second power supply, which is not limited herein. Specifically, the first power supply 13 and the second power supply are both cuboid structures and are both rechargeable batteries.

[0072] Referring to Figure 9 In an embodiment, the body 24 includes a box body 241 and a filter assembly 242. The air inlet 22 and the dust collecting cavity 21 are arranged on the box body 241, and the filter assembly 242 is detachably assembled on the box body 241. The filter element 2421 of the filter assembly 242 is located on the flow path of the airflow flowing from the dust collecting cavity 21 to the outside. One of the box body 241 and the filter assembly 242 is provided with a track 243 having an opening at one end, and the other is provided with a sliding block 244. The sliding block 244 can slide into or out of the track 243 from the end of the track 243 having the opening. The filter assembly 242 is assembled by cooperation of the sliding block 244 and the track 243. In this way, when the filter assembly 242 needs to be assembled on the box body 241, the sliding block 244 slides along the track 243 to assemble the filter assembly 242 on the box body 241. When the filter assembly 242 needs to be detached from the box body 241, the sliding block 244 slides reversely along the track 243 to detach the filter assembly 242 from the box body 241, so as to facilitate assembly and disassembly of the filter assembly 242.

[0073] Specifically, the track 243 is disposed on the housing 241, and the slider 244 is disposed on the filter assembly 242. When the filter assembly 242 needs to be assembled onto the housing 241, the slider 244 on the filter assembly 242 slides from the open end of the track 243 into the track 243 to assemble the filter assembly 242 onto the housing 241. When the filter assembly 242 needs to be removed from the housing 241, the slider 244 on the filter assembly 242 slides out of the open end of the track 243 to remove the filter assembly 242 from the housing 241. Of course, in another embodiment, the track 243 may also be disposed on the filter assembly 242, and correspondingly, the slider 244 may be disposed on the housing 241; this is not limited here.

[0074] See Figure 10 and Figure 11 The filter assembly 242 also includes a fitting 2422, on which the filter element 2421 is fitted and the slider 244 is mounted.

[0075] Specifically, the filter element 2421 and the assembly 2422 are assembled as a single unit. Therefore, when the filter element 2421 needs to be assembled onto the housing 241, the integrated filter element 2421 and the assembly 2422 can be assembled together onto the housing 241, avoiding the need to assemble the filter element 2421 first and then the assembly 2422. When the filter element 2421 needs to be removed from the housing 241, only the integrated filter element 2421 and the assembly 2422 need to be removed together from the housing 241, avoiding the need to disassemble the assembly 2422 first and then the filter element 2421, thus facilitating the assembly and disassembly of the filter element 2421. Specifically, the filter assembly 242 also includes an adhesive component, through which the filter element 2421 is bonded to the assembly 2422. Of course, in other embodiments, the filter element 2421 can also be assembled with the assembly 2422 in other ways, which is not limited here.

[0076] Assembly component 2422 has a dust collection chamber 21 connected to an assembly cavity 2423 (see reference). Figure 12 The filter element 2421 is assembled in the assembly cavity 2423, and the air outlet 23 is provided on the assembly part 2422 and communicates with the assembly cavity 2423. In a specific embodiment, in the first direction Y, the air outlet 23 is provided on one side of the assembly part 2422, the length of the assembly part 2422 in the longitudinal direction X of the body 24 is a first length L1, and the length of the air outlet 23 in the longitudinal direction X of the body 24 is a second length L2, the second length L2 being 2 / 5 to 2 / 3 times the first length L1.

[0077] In one specific embodiment, the plane containing the filter element 2421 is inclined relative to the direction of gravity. That is, the distance between one end of the filter element 2421 and the bottom surface of the body 24 is not equal to the distance between the other end of the filter element 2421 and the bottom surface. In this way, with the plane containing the filter element 2421 parallel to the direction of gravity, dust adhering to the filter element 2421 can easily slide down into the dust collection chamber 21 under the action of gravity.

[0078] Continue reading Figure 12 The main body 24 also includes a sealing element 245, which is disposed between the mounting part 2422 and the box body 241 to seal the mounting part 2422 and the box body 241, preventing air from escaping to the outside through the gap between the mounting part 2422 and the box body 241. Specifically, the sealing element 245 is sealing cotton. In some other embodiments, the sealing element 245 may also be a sealing ring or other sealing structure, which is not limited here.

[0079] In one embodiment, the housing 241 has rails 243 on opposite sides, and the mounting component 2422 has sliders 244 on opposite sides. The sliders 244 on both sides of the mounting component 2422 cooperate with the rails 243 on both sides to facilitate the assembly and disassembly of the filter assembly 242.

[0080] Continue reading Figure 9 The filter assembly 242 is assembled on the top of the box 241. Specifically, the top of the box 241 is provided with a receiving portion 2411, the receiving portion 2411 has a receiving cavity 2412, and the side of the receiving portion 2411 is provided with a first notch 2413 communicating with the receiving cavity 2412. The filter assembly 242 is inserted into the receiving portion 2411 through the first notch 2413 and is at least partially received in the receiving cavity 2412.

[0081] The aforementioned track 243 is disposed on the receiving portion 2411, and the slider 244 is disposed on the assembly 2422. The filter assembly 242 is assembled with the track 243 via the slider 244. A first locking portion is provided on the inner wall of the receiving cavity 2412, and a second locking portion is provided on the assembly 2422. The filter assembly 242 is assembled within the receiving cavity 2412, and the first and second locking portions engage to restrict the movement of the assembly 2422 relative to the receiving portion 2411 in the assembly direction. That is, when the slider 244 slides into position within the track, the first and second locking portions engage and fix the filter assembly 242 securely to the housing 241.

[0082] The first engaging portion is located on the inner wall of the receiving cavity 2412 opposite to the first notch 2413. The remaining portion of the first engaging portion is located on the inner wall of the receiving cavity 2412 where the track 243 or slider 244 is located. The second engaging portion is positioned corresponding to the first engaging portion. That is, the first engaging portion is located on the sliding path where the slider 244 and the slide rail cooperate, the remaining portion of the first engaging portion is located on the same side as the track 243 or slider 244, and the second engaging portion is positioned corresponding to the first engaging portion.

[0083] Specifically, the first engaging portion includes a first sub-engaging portion 2461 and a second sub-engaging portion 2462. The first sub-engaging portion 2461 is disposed on the inner wall of the receiving cavity 2412 opposite to the first notch 2413, and the second sub-engaging portion 2462 is disposed on the inner wall of the receiving cavity 2412 where the track 243 is provided. The second engaging portion includes a third sub-engaging portion 2471 (see reference). Figure 11 The third sub-clamping part 2471 is located at the end of the assembly 2422 that slides into the receiving cavity 2412, and the fourth sub-clamping part 2472 is located on the side of the assembly 2422 where the slider 244 is located. When the slider 244 slides into position within the track 243, each third sub-clamping part 2471 engages with each first sub-clamping part 2461, and each fourth sub-clamping part 2472 engages with each second sub-clamping part 2462, to ensure the stability of the filter assembly 242 assembled on the housing 241.

[0084] In one embodiment, the top of the receiving cavity 2412 is provided with a second notch 2414, and the top surface of the dust collection box 20 is formed on the mounting part 2422. A first anti-detachment part 248 is provided inside the receiving cavity 2412, and a second anti-detachment part 249 is provided on the mounting part 2422. The second anti-detachment part 249 and the first anti-detachment part 248 are mutually restrictive to prevent the mounting part 2422 from being dislodged from the receiving cavity 2412 through the second notch 2414. By providing the first anti-detachment part 248 and the second anti-detachment part 249 to restrict the dislodging, the filter assembly 242 is prevented from being dislodged from the receiving cavity 2412 through the second notch 2414 when subjected to an upward force after being assembled onto the box body 241.

[0085] One of the first anti-detachment part 248 and the second anti-detachment part 249 is a limiting groove, with an opening at one end in the assembly direction of the fitting 2422 and the receiving part 2411. The other of the first anti-detachment part 248 and the second anti-detachment part 249 is a plug-in part. The width of the limiting groove gradually decreases from the end with the opening to the end away from the opening. The plug-in part is inserted into the limiting groove from the opening and gradually fits tightly with the limiting groove from the end with the opening to the end away from the opening.

[0086] With the above settings, as the slider 244 slides into the track 243, the insertion part gradually inserts into the narrower end of the limiting groove from the wider end. This ensures that the insertion part and the limiting groove fit more and more tightly, further preventing the filter component 242 from coming out of the receiving cavity 2412 from the second notch 2414.

[0087] In one specific embodiment, the assembly 2422 includes a first plate 24221, a second plate 24222, and a third plate 24223 (see reference). Figure 11 and Figure 12 The first plate 24221 is connected to the second plate 24222 and is perpendicular to each other. The two ends of the third plate 24223 are connected to the first plate 24221 and the second plate 24222 respectively. The first plate 24221, the second plate 24222 and the third plate 24223 define and form an assembly cavity 2423 that communicates with the dust collection cavity 21. In this embodiment, the top surface of the dust collection box 20 is formed on the first plate 24221, the third sub-clamping part 2471 is connected to the first plate 24221, the second plate 24222 forms part of the side surface of the dust collection box 20, the fourth sub-clamping part 2472 is connected to the second plate 24222, the first plate 24221 or the second plate 24222 is provided with an air outlet 23 communicating with the assembly cavity 2423, the third plate 24223 is located in the receiving cavity 2412, the filter element 2421 is disposed in the assembly 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 arrangement of the assembly 2422 is not limited to this, nor is it limited here.

[0088] Specifically, the third plate 24223 is grid-shaped, which supports the filter element 2421 while facilitating airflow from the dust collection chamber 21 into the assembly chamber 2423.

[0089] See Figure 13 In one embodiment, the outer surface of the assembly 2422 is also provided with a recessed portion 24224 that is easy to grip. Thus, when it is necessary to disassemble or assemble the filter assembly 242, you only need to grip the recessed portion 24224 to operate the filter assembly 242.

[0090] In one embodiment, the dust collection box 20 also includes a trigger 25 (see [reference]). Figure 3 and Figure 10The outer surface of the assembly 2422 or the housing 241 has an assembly part 26, and 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. The triggered part uses the trigger 25 to determine whether the dust collection box 20 is assembled, thereby determining whether the sweeping robot 100 has the conditions for normal operation. When the triggered part does not sense the trigger 25, the sweeping robot 100 determines that the dust collection box 20 is not assembled, and at this time the sweeping robot 100 does not have the conditions for normal operation; if the triggered part senses the trigger 25, the sweeping robot 100 determines that the dust collection box 20 is assembled, and at this time the sweeping robot 100 has the conditions for normal operation.

[0091] The above-mentioned assembly part 26 is provided on the outer surface of the assembly part 2422 or the box 241. The trigger 25 is assembled in the assembly part 26. Since the filter 2421 is assembled in the assembly cavity 2423 of the assembly part 2422, that is, the filter 2421 is located inside the assembly part 2422, when the trigger 25 needs to be replaced, it is no longer necessary to remove the filter 2421 (since the filter 2421 is generally glued to the assembly part 2422, if the filter 2421 is removed, it will be damaged or even unusable). The replacement of the trigger 25 is convenient.

[0092] It should be noted that the outer surface of the aforementioned assembly 2422 refers to the outer surface before the filter assembly 242 is assembled onto the housing 241. When the assembly 2422 is assembled onto the housing 241, part of the outer surface will inevitably be covered by the housing 241.

[0093] Specifically, the trigger 25 is a magnet. When the triggered element does not sense the magnet, the robot vacuum cleaner 100 determines that the dust collection box 20 is not installed, and the robot vacuum cleaner 100 does not have the conditions for normal operation; if the triggered element senses the magnet, the robot vacuum cleaner 100 determines that the dust collection box 20 is installed, and the robot vacuum cleaner 100 has the conditions for normal operation.

[0094] In one specific embodiment, when the filter assembly 242 is assembled onto the housing 241, the assembly portion 26 is hidden from the outside, and the trigger element 25 assembled onto the assembly portion 26 is also hidden from the outside. It should be understood that in another embodiment, when the filter assembly 2423 is assembled onto the housing 241, the assembly portion 26 is exposed to the outside, and the trigger element 25 is also exposed to the outside.

[0095] Specifically, the assembly part 26 is an assembly groove provided on the outer surface of the assembly 2422 or the housing 241, and the trigger member 25 is received in the assembly groove. Of course, in some other embodiments, the assembly part 26 may also be an assembly hole provided on the outer surface of the assembly 2422 or the housing 241, which is not limited here.

[0096] In one specific embodiment, the assembly part 26 is located on the side of the assembly 2422 or the housing 241 that has the track 243 or the slider 244. When the filter assembly 242 is assembled onto the housing 241 via the slider 244 and the track 243, both the assembly part 26 and the trigger 25 are hidden from view. (Continue reading) Figure 11 The assembly 2422 also includes a connecting portion, and the second anti-detachment portion 249 is connected to the second plate 24222 of the assembly 2422 via the connecting portion. An assembly groove is provided on the connecting portion. It should be understood that in some embodiments, the location of the assembly groove is not limited.

[0097] See Figure 14 and Figure 15 In one embodiment, the dust collection box 20 further includes a handle 27, which is pivotally connected to the box body 241 and can switch between a vertically positioned lifting position and a horizontally positioned limiting position relative to the box body 241. A first limiting portion 271 is provided on the surface of the handle 27 facing away from the box body 241, and a second limiting portion 111 is provided on the shell 11 of the robotic vacuum cleaner 100. When the handle 27 is in the limiting position, the first limiting portion 271 can cooperate with the second limiting portion 111 to limit the position of the dust collection box 20, thereby ensuring that the dust collection box 20 is properly assembled (see...). Figure 16 ).

[0098] By providing a first limiting part 271 on the surface of the handle 27 away from the box body 241, the volume occupied by the limiting mechanism on the handle 27 is reduced, thereby increasing the volume occupied by other structures of the sweeping robot 100 and reducing unnecessary waste of space.

[0099] Furthermore, the first limiting part 271 is a protrusion on the surface of the handle 27, and the second limiting part 111 is a groove that mates with the protrusion. Of course, in some other embodiments, the first limiting part 271 may be a groove recessed on the surface of the handle 27, and the second limiting part 111 may be a protrusion that mates with the first limiting part 271; this is not limited here.

[0100] When the first limiting part 271 and the second limiting part 111 are configured with a structure in which the protrusion and the groove cooperate, the handle 27 assembles the dust collection box 20 onto the main body 10 of the sweeping robot 100, and then the handle 27 is operated to switch from the lifting position to the limiting position, so that the protrusion and the groove cooperate to limit the dust collection box 20 onto the main body 10 of the sweeping robot 100.

[0101] Furthermore, each end of the handle 27 is provided with a first limiting part 271, and the first limiting part 271 at both ends of the handle 27 is symmetrically arranged with respect to the center line of the handle 27 (in order to distinguish it from the first center line X1 and the second center line X2 mentioned above, the center line of the handle 27 is defined as the third center line), thereby ensuring the stability of the limiting.

[0102] See Figures 17-19 The end of the handle 27 forms a first arc-shaped guide mating surface 272, and the shell 11 of the sweeping robot 100 forms a second guide mating surface 112. During the switching between the lifting position and the limiting position, the first guide mating surface 272 and the second guide mating surface 112 on the body 10 of the sweeping robot 100 guide and engage, making it easy for the handle 27 to switch between the lifting position and the limiting position.

[0103] Furthermore, the handle 27 is provided with a first rotating engagement part 273, and the housing 11 of the robotic vacuum cleaner 100 is provided with a second rotating engagement part 113. During the process of switching between the lifting position and the limiting position of the handle 27, the first rotating engagement part 273 and the second rotating engagement part 113 rotate and engage. And when the handle 27 is in the limiting position, the first rotating engagement part 273 and the second rotating engagement part 113 engage to limit the handle 27 from continuing to rotate from the lifting position toward the limiting position.

[0104] With the above configuration, the first rotating engagement part 273 and the second rotating engagement part 113 facilitate the switching of the handle 27 between the lifting position and the limiting position. When the handle 27 is in the limiting position, the first rotating engagement part 273 and the second rotating engagement part 113 engage in a limiting engagement to restrict the handle 27 from continuing to rotate from the lifting position toward the limiting position. At the same time, the first limiting part 271 and the second limiting part 111 engage in a limiting engagement, providing a dual-action limiting of the handle 27 and ensuring the stability of the dust collection box 20's limiting position.

[0105] Specifically, the first rotating fitting part 273 extends on the handle 27 along the extension direction perpendicular to the handle 27, and the first rotating fitting part 273 is an arc-shaped groove or a semi-circular block with an opening.

[0106] It should be noted that the above-mentioned semi-circular block is not just half of a circle. In this embodiment, any shape whose cross-sectional shape includes an interconnected arc and a straight line is classified as a semi-circular block.

[0107] In one specific embodiment, the first rotating mating part 273 is a semi-circular block, and the second rotating mating part 113 is an arc-shaped groove with an opening. Of course, in another embodiment, the first rotating mating part 273 can also be an arc-shaped groove with an opening, and the second rotating mating part 113 can be a semi-circular block; this is not limited here.

[0108] Another embodiment of the present invention provides a dust collection box 20 included in the above-mentioned sweeping robot 100, including a box body 241 and a filter assembly 242. The box body 241 has an air inlet 22 and an air outlet 23. The filter assembly 242 includes a filter element 2421 and an assembly 2422 assembled together, with the filter element 2421 assembled on the assembly 2422. The filter assembly 242 is detachably assembled on the box body 241 and defines a dust collection chamber 21 communicating with the air inlet 22. The filter element 2421 is located on the flow path of airflow from the dust collection chamber 21 to the air outlet 23.

[0109] The dust collection box 20 provided in this embodiment of the invention allows for the assembly of the filter element 2421 onto the box body 241 when the filter element 2421 needs to be assembled thereon. This avoids assembling the filter element 2421 first and then the assembly element 2422. When the filter element 2421 needs to be removed from the box body 241, only the filter element 2421 and the assembly element 2422 need to be removed together from the box body 241. This avoids disassembling the assembly element 2422 first and then the filter element 2421, making it easier to assemble and disassemble the filter element 2421.

[0110] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0111] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
