[0045] See also Figure 1 An embodiment of the present invention provides a sweeping robot 100, including a main body 10 and a dust box 20. The dust box 20 is disposed on the main body 10 and is used to collect dust. When the dust in the dust box 20 reaches a certain volume, the user can remove the dust box 20 from the main body 10 to empty the dust. After emptying the dust, the dust box 20 is assembled on the main body 10 to collect dust again.

[0046] See also Figure 2 The dust collecting box 20 is provided with a dust collecting chamber 21, and the dust collecting box 20 is provided with an air inlet 22 and an air outlet 23 both connected to the dust collecting chamber 21 (see Figure 3), the sweeping robot 100 further includes a roller brush assembly and an air duct assembly, the roller brush assembly is connected to the air inlet 22, and the air duct assembly is connected to the air outlet 23. The roller brush assembly is used to collect dust on the ground, and the air duct assembly includes an air duct and a power member, and the air duct is connected between the air outlet 23 of the dust box 20 and the power member, and the power member is used to provide power for the airflow to flow from the roller brush assembly to the dust box 20, and from the dust box 20 to the air duct. During the flow, the airflow carries the dust collected by the roller brush assembly into the dust box 20, and is retained in the dust collection chamber 21 under the action of the filter 252 in the dust box 20, and the clean airflow flows to the outside again from the air duct.

[0047] Continue reading Figure 3 The dust collecting box 20 includes a box body 24 and a filter assembly 25. The air inlet 22 and the dust collecting chamber 21 are both provided on the box body 24. The filter assembly 25 includes an assembly part 251 and a filter element 252. The filter element 252 is installed on the assembly part 251. The assembly part 251 has a locking position that can be locked with the box body 24 and an unlocking position that can be unlocked relative to the box body 24. When the assembly part 251 is in the locking position, the filter element 252 is located on the flow path of the airflow from the dust collecting chamber 21 to the air outlet 23.

[0048] When a pressing force is applied to the assembly part 251 in the first direction, the assembly part 251 can be switched from one of the locked position and the unlocked position to the other. That is, when the assembly part 251 needs to be switched from the locked position to the unlocked position, the switching can be completed by pressing the assembly part 251 in the first direction; when the switching needs to be switched from the unlocked position to the locked position, the switching can be completed by pressing the assembly part 251 again in the first direction.

[0049] Through the above arrangement, when the filter element 252 needs to be cleaned, it is only necessary to press the assembly part 251 in the first direction to remove the filter component 25 from the box body 24 to clean the filter element 252. When the cleaning is completed, it is only necessary to press the assembly part 251 in the first direction again to assemble the filter component 25 on the box body 24. The filter component 25 is easy to disassemble and assemble.

[0050] In one embodiment, a receiving portion 241 is provided at the top of the box body 24, the receiving portion 241 has a receiving cavity 242 communicating with the dust collecting cavity 21, a second notch 243 communicating with the receiving cavity 242 is provided at the side of the receiving cavity 242, and an assembly part 251 is inserted into the receiving portion 241 through the second notch 243 and at least partially accommodated in the receiving cavity 242. Specifically, a third notch 244 communicating with the dust collecting cavity 21 is provided at the top of the receiving portion 241, and the top surface of the dust collecting box 20 is formed on the assembly part 251.

[0051] The dust box 20 further includes a sealing member, which is disposed between the assembly member 251 and the box body 24. When the assembly member 251 is in the locked position, the sealing member can seal the assembly member 251 and the box body 24 to prevent airflow from escaping from between the assembly member 251 and the box body 24 to the outside. Specifically, the sealing member is a sealing cotton. In other embodiments, the sealing member can also be a sealing structure such as a tight rubber ring, which is not limited here.

[0052] See also Figure 4 In one embodiment, an assembly cavity 2511 communicating with the dust collecting cavity 21 is provided in the assembly part 251, and the filter element 252 is provided in the assembly cavity 2511. The air outlet 23 is provided on the assembly part 251 and communicated with the assembly cavity 2511. It should be understood that in other embodiments, the assembly cavity 2511 may be omitted from the assembly part 251, which is not limited here. Specifically, the filter assembly 25 also includes an adhesive, and the filter element 252 is bonded to the assembly part 251 as a whole through the adhesive. Of course, in other embodiments, the filter element 252 may also be assembled into a whole with the assembly part 251 in other ways, which is also not limited here.

[0053] The plane where the filter element 252 is located is tilted relative to the direction of gravity. That is, the distance between one end of the filter element 252 and the bottom surface of the box body 24 is not equal to the distance between the other end of the filter element 252 and the bottom surface of the box body 24. In this way, compared with the case where the plane where the filter element 252 is located is parallel to the direction of gravity, it is convenient for dust adhering to the filter element 252 to slide down into the dust collecting chamber 21 under the action of gravity.

[0054] See also Figure 5 In one embodiment, a pressing rod 26 is provided on one of the box body 24 and the assembly part 251, and a locking member 27 is provided on the other; when the assembly part 251 is in the locked position, the locking member 27 is locked with the pressing rod 26, and the filter assembly 25 cannot be removed from the box body 24 at this time; when the assembly part 251 is in the unlocked position, the locking member 27 is separated from the pressing rod 26, and the filter assembly 25 can be removed from the box body 24. Specifically, the locking member 27 is provided on the cavity wall of the accommodating cavity 242 facing the second notch 243, and the pressing rod 26 is provided on the assembly part 251. It should be understood that in other embodiments, the locking member 27 can also be provided on the assembly part 251, and the pressing rod 26 can be provided on the box body 24, which is not limited here.

[0055] Furthermore, the locking member 27 is convexly disposed on the surface of the box body 24, and the pressing rod 26 is convexly disposed on the surface of the assembly member 251. Of course, in other embodiments, a mounting hole may be provided on the box body 24, and the locking member 27 is disposed in the mounting hole.

[0056] See also Figure 6 and Figure 7The locking member 27 includes a lock housing 271 and a lock head 272. The lock head 272 includes a lock body 273 and a lock claw 274. The lock housing 271 is provided with a mounting cavity 2711, and the lock housing 271 is also provided with an opening 2712 communicating with the mounting cavity 2711. The lock body 273 is disposed in the mounting cavity 2711 through the opening 2712, and the lock claw 274 is connected to an end of the lock body 273 near the opening 2712. When the assembly part 251 is in the locking position, the lock body 273 moves relative to the lock housing 271 under the pressing action of the pressing rod 26 until the lock claw 274 is locked with the pressing rod 26; when the assembly part 251 is in the unlocking position, the lock body 273 moves relative to the lock housing 271 under the pressing action of the pressing rod 26 until the lock claw 274 is separated from the pressing rod 26.

[0057] There are multiple locking claws 274. When the assembly part 251 is in the locking position, the multiple locking claws 274 are close to each other and locked with the pressing rod 26. When the assembly part 251 is in the unlocking position, the multiple locking claws 274 are separated from each other and the pressing rod 26.

[0058] In a specific embodiment, the locking claws 274 include two oppositely disposed ones. The pressing rod 26 includes a connecting portion 261 and a pressing portion 262, wherein the connecting portion 261 is connected to the assembly part 251, and the pressing portion 262 is connected to the connecting portion 261 for pressing the lock body 273. The connecting portion 261 is in a rectangular parallelepiped shape, and the pressing portion 262 is in a prism shape. The lower bottom surface of the prism is connected to the connecting portion 261, and the projection of the connecting portion 261 on the lower bottom surface of the prism is located inside the lower bottom surface. When the assembly part 251 is in the locked position, the two locking claws 274 are close to each other and abut against the surfaces of the connecting portion 261 and the pressing portion 262 to limit the pressing rod 26, thereby keeping the assembly part 251 in the locked position.

[0059] It is conceivable that in other embodiments, the number of the locking claws 274 is not limited, and the shape of the pressing rod 26 is also not limited.

[0060] Specifically, when the assembly 251 switches from the unlocked position to the locked position, the lock body 273 moves in the lock housing 271 in the first direction toward the bottom wall of the mounting cavity 2711. The locking claw 274 is elastic. When the assembly 251 is in the locked position, the locking claw 274 is elastically deformed and brought closer to each other under the action of the inner wall of the mounting cavity 2711; when the assembly 251 is in the unlocked position, the locking claw 274 elastically recovers and separates from each other. It is understandable that in other embodiments, the locking claw 274 can also be arranged to be rotatably connected to the lock body 273. When the assembly 251 is in the locked position, the locking claw 274 is rotated relative to the lock body 273 under the action of the inner wall of the mounting cavity 2711 and brought closer to each other; when the assembly 251 is in the unlocked position, the locking claw 274 is separated from each other under the action of other structures.

[0061] See also Figure 8 and Fig. 9 In one embodiment, the locking member 27 further comprises an elastic member 275, and the elastic member 275 is disposed between the lock body 273 and the bottom wall of the installation cavity 2711. The locking member 27 further comprises a supporting member 277, one end of which is rotatably connected to the cavity wall of the installation cavity 2711, a first limiting portion 276 is convexly provided on the first side surface of the lock body 273, and a first hook 2771 is disposed at the other end of the supporting member 277, and the first hook 2771 is in contact with the first side surface of the lock body 273; when the assembly member 251 switches between the locking position and the unlocking position, the first hook 2771 switches between the first position and the second position relative to the lock body 273 (see Figure 8 and Fig. 9 When the first hook 2771 switches between the first position and the second position, the first hook 2771 rotates in a clockwise direction relative to the first limiting portion 276). When the assembly 251 is in the locked position, the first hook 2771 is in the first position, and the first hook 2771 cooperates with the first limiting portion 276 to limit the movement of the lock body 273 relative to the lock shell 271.

[0062] That is, in this embodiment, when the filter assembly 25 needs to be assembled on the box body 24, the assembly part 251 is pressed in the first direction, at which time the pressing rod 26 presses the lock body 273, the elastic member 275 is compressed and deformed, the support member 277 rotates relative to the cavity wall of the installation cavity 2711, and the first hook 2771 at the other end of the support member 277 switches from the second position to the first position to hook the first limiting portion 276, at which time the position of the lock body 273 relative to the lock shell 271 is fixed. At the same time, the multiple locking claws 274 are elastically deformed under the action of the inner wall of the installation cavity 2711, and are brought close to each other and locked with the pressing rod 26, and the assembly of the filter assembly 25 and the box body 24 is completed. When the filter assembly 25 needs to be removed from the box body 24, the assembly part 251 is pressed in the first direction again, and the pressing rod 26 presses the lock body 273 again, and the support member 277 rotates relative to the cavity wall of the installation cavity 2711, and the first hook 2771 at the other end of the support member 277 switches from the first position to the second position, and the first hook 2771 separates from the first limiter 276, and the elastic member 275 elastically recovers. At the same time, the multiple locking claws 274 elastically recover and separate from each other and the pressing rod 26, and the filter assembly 25 and the box body 24 are completely removed.

[0063] The elastic member 275 is a spring. Of course, in other embodiments, the elastic member 275 can also be an elastic rubber member. The locking member 27 also includes a guide column 279 disposed in the mounting cavity 2711. One end of the guide column 279 is fixedly connected to the lock shell 271. A guide hole is provided on the lock body 273. The other end of the guide column 279 is movably disposed in the guide hole. Through the cooperation between the guide column 279 and the guide hole, the lock body 273 can move straight up and down in the lock shell 271. Specifically, the elastic member 275 is sleeved outside the guide column 279. It is understandable that in other embodiments, the elastic member 275 can also be disposed independently of the guide column 279.

[0064] See also Fig.10 and Fig.11 In one embodiment, the other end of the support member 277 is provided with a second hook portion 2772, and the second limiting portion 278 is provided on the second side surface of the lock body 273 opposite to the first side, and the second limiting portion 278 abuts against the second side surface of the lock body 273; when the assembly part 251 switches between the locked position and the unlocked position, the second hook portion 2772 switches between the third position and the fourth position relative to the lock body 273 (see Fig.10 and Fig.11 , the second hook 2772 rotates in a clockwise direction relative to the second limiting portion 278), when the assembly 251 is in the unlocked position, the second hook 2772 is in the fourth position, and the second hook 2772 cooperates with the second limiting portion 278 to limit the movement of the lock body 273 relative to the lock shell 271.

[0065] In this embodiment, when the filter assembly 25 needs to be assembled on the box body 24, the assembly part 251 is pressed in the first direction, at which time the assembly part 251 presses the lock body 273, the elastic part 275 is compressed and deformed, the support member 277 rotates relative to the cavity wall of the installation cavity 2711, the first hook 2771 at the other end of the support member 277 switches from the second position to the first position to hook the first limiting part 276, and the second hook 2772 at the other end of the support member 277 switches from the fourth position to the third position to disengage from the second limiting part 278. At this time, since the first limiting part 276 is hooked by the first hook 2771, the position of the lock body 273 relative to the lock shell 271 is fixed, ensuring that the locking claw 274 always locks the pressing rod 26. At the same time, the multiple locking claws 274 are elastically deformed under the action of the inner wall of the installation cavity 2711, close to each other and locked with the pressing rod 26, and the assembly of the filter assembly 25 and the box body 24 is completed. When it is necessary to remove the filter assembly 25 from the box body 24, the assembly part 251 is pressed in the first direction again. At this time, the pressing rod 26 presses the lock body 273 again, and the support member 277 rotates relative to the cavity wall of the installation cavity 2711. The first hook 2771 at the other end of the support member 277 switches from the first position to the second position, and the second hook 2772 at the other end of the support member 277 switches from the third position to the fourth position to hook the second limiting portion 278. At this time, the second limiting portion 278 is hooked by the second hook 2772, and the position of the lock body 273 relative to the lock shell 271 is fixed to ensure that the lock body 273 cannot escape from the lock shell 271.

[0066] See also Fig.12 Specifically, the support member 277 includes a rotating portion 2773 and the first hook portion 2771 and the second hook portion 2772. The rotating portion 2773 is rotatably connected to the cavity wall of the installation cavity 2711. The first hook portion 2771 and the second hook portion 2772 are connected to the same side of the rotating portion 2773 and extend in the same direction. The ends of the first hook portion 2771 and the second hook portion 2772 away from the rotating portion 2773 are bent toward each other, and a first notch 2774 is formed between the first hook portion 2771 and the second hook portion 2772. The support member 277 is clamped outside the lock body 273 through the first notch 2774. It can be understood that in other embodiments, the support member 277 can also be arranged in other ways, which is not limited here.

[0067] The locking member 27 further includes a limiting column 2710, which is connected to the lock body 273. The lock shell 271 is provided with a limiting hole 2713 which is connected to the installation cavity 2711 and extends along the first direction. The limiting column 2710 is slidably arranged in the limiting hole 2713 along the first direction. Through the above arrangement, the up and down movement range of the lock body 273 in the lock shell 271 is limited to prevent the lock body 273 from coming out of the lock shell 271. At the same time, the limiting column 2710 cooperates with the limiting hole 2713 to play a certain guiding role. Specifically, in a direction perpendicular to the first direction, the size of the limiting hole 2713 matches that of the limiting column 2710, so as to limit the position of the lock body 273 in the lock shell 271 in the direction perpendicular to the first direction.

[0068] In one embodiment, a track 28 is provided on one of the assembly part 251 and the box body 24, and a slider 29 is provided on the other.

Specifically, the track 28 is provided on the side wall of the accommodating cavity 242, and the slider 29 is provided on the assembly part 251. When the filter assembly 25 needs to be assembled on the box body 24, the slider 29 is provided in the track 28, and the assembly part 251 is pressed in the first direction. When the pressing rod 26 contacts the lock body 273, the pressing rod 26 presses the lock body 273, and the lock body 273 compresses the elastic member 275 under the guidance of the guide column 279. The first hook 2771 of the support member 277 switches from the second position to the first position to hook the first limiting portion 276, the second hook 2772 switches from the fourth position to the third position to disengage from the second limiting portion 278, and the locking claw 274 elastically contracts and approaches to be locked with the pressing rod 26 under the action of the cavity wall of the installation cavity 2711. When it is necessary to remove the filter assembly 25 from the box body 24, the assembly part 251 is pressed again in the first direction, the first hook 2771 of the support rod switches from the first position to the second position to disengage from the first limiting portion 276, the second hook 2772 switches from the third position to the fourth position to hook the second limiting portion 278, and the locking claw 274 elastically recovers and separates from the pressing rod 26. Then, in the opposite direction to the first direction, the assembly part 251 is pulled outward to remove the filter assembly 25 from the box body 24.

[0069] Through the above arrangement, when the filter assembly 25 is assembled on the box body 24 , the pressing rod 26 is locked by the locking member 27 , and the slider 29 is arranged in the track 28 , thereby ensuring the stability of the filter assembly 25 assembled on the box body 24 .

[0070] Rails 28 are provided on opposite sides of one of the box body 24 and the assembly part 251 , and sliders 29 are provided on opposite sides of the other one. The sliders 29 on each side slide in cooperation with the rails 28 on each side to further ensure the assembly stability of the filter assembly 25 .
