Description

Technical Field

[0001] This invention relates to the field of cleaning robot technology, and more particularly to a dustbin and a cleaning robot. Background Technology

[0002] The cleaning robot includes a dustbin with a receiving cavity inside. The receiving cavity is used to hold the dust bag, which is connected to the suction pipe outside the receiving cavity. When the dust bag is replaced, the dust inside the dust bag can easily fly out from the dust bag opening, causing secondary pollution.

[0003] To avoid secondary pollution, current methods involve installing dust guide holes, mounting brackets, and partition assemblies on the housing. The dust guide holes are connected to the suction pipe. Selective connection between the dust guide holes and the dust bags is achieved by moving the pull-out plate of the partition assembly. However, the connection structure between the partition assembly and the mounting bracket in existing technology is flawed, making dust bag replacement inconvenient. Furthermore, the negative pressure environment inside the housing during robot operation causes the pull-out plate to deform under prolonged negative pressure, leading to difficulty in pulling it out, reduced dust bag effectiveness, and a negative impact on the user experience. Summary of the Invention

[0004] The purpose of this invention is to provide a dustbin and a cleaning robot that prevents the moving parts from deforming under negative pressure, thus avoiding obstruction of movement when changing dust bags and improving the user experience.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A dustbin includes a housing, a connecting assembly, and a dust bag. The housing has dust guide holes. The connecting assembly installs the dust bag into the housing and can connect or close the dust guide holes with the internal space of the dust bag.

[0007] The connecting component includes a mounting part and a movable part. The mounting part has a mounting hole, the dust bag is installed in the mounting hole, and the inner wall of the box has a fixing structure. The mounting part is connected to the fixing structure.

[0008] The movable component is slidably disposed between the mounting component and the fixed structure. The movable component is provided with a through hole that can connect the dust guide hole and the mounting hole.

[0009] The fixing structure includes a first sliding groove and a first locking groove. The first sliding groove is located below the first locking groove. The moving part includes a first buckle and a second buckle. Both the first buckle and the second buckle are located at the upper end of the moving part. The lower part of the moving part is inserted into the first sliding groove. The first buckle engages with the first locking groove, and the second buckle engages with the top end of the mounting part.

[0010] As an optional solution for the dustbin, the fixing structure also includes two guide grooves and two first snap-fit ​​parts arranged opposite to each other. The two guide grooves are located below the first snap-fit ​​parts. One end of the mounting member cooperates with the two guide grooves, and the other end snaps with the two first snap-fit ​​parts.

[0011] As an optional solution for the dustbin, the inner wall of the box is provided with two fixing blocks arranged opposite each other. The first snap-fit ​​part is provided on the side of the two fixing blocks that are close to each other. The first snap-fit ​​part includes a second slot. The mounting part is provided with two elastic buckles arranged opposite each other. The elastic buckles can engage with the second slot.

[0012] As an optional solution for the dustbin, the mounting component includes a mounting plate and two connecting plates, the mounting plate is disposed between the two connecting plates, the mounting hole is disposed on the mounting plate, and the elastic buckle is disposed on the connecting plates;

[0013] Each of the two connecting plates is provided with a limiting plate on one side that is close to each other. A second sliding groove is formed between the limiting plate and the mounting plate, and the moving part is slidably disposed in the second sliding groove.

[0014] As an optional solution for the dustbin, the movable component includes a first side and a second side. The first side is disposed near the inner wall of the dustbin body, and the second side is disposed near the mounting component. A first limiting groove is provided at the bottom end of the mounting plate, and a first limiting protrusion is provided at the bottom end of the second side. The first limiting protrusion can cooperate with the first limiting groove to limit the movement of the movable component to a first extreme position; and / or,

[0015] The first side is provided with a second limiting protrusion on both sides. The second limiting protrusion can abut against the bottom of the limiting plate to limit the movement of the moving part to the first extreme position.

[0016] As an optional solution for the dustbin, a first rubber ring is provided in the mounting hole, and a second rubber ring is provided in the through hole, wherein the inner diameter of the second rubber ring is smaller than the inner diameter of the first rubber ring.

[0017] As an alternative to the dustbin, the first snap-fit ​​portion further includes a guide surface, and the second slot is located below the guide surface. The guide surface is configured as an inclined surface, and the inclined surface gradually approaches the mounting component from the top of the fixing block toward the second slot.

[0018] As an alternative to the dustbin, the movable component is provided with a movable handle on the side away from the mounting component, and a reinforcing rib is connected between the movable handle and the first buckle.

[0019] As an alternative to the dustbin, the fixing structure also includes a limiting block, and the movable handle abuts against the limiting block to limit the second extreme position of the movable component.

[0020] A cleaning robot, comprising a cleaning body and a dustbin disposed on the cleaning body as described in any of the above embodiments.

[0021] The beneficial effects of this invention are:

[0022] The dustbin provided by this invention has dust guide holes on its body. A connecting assembly installs a dust bag inside the dustbin and can connect or close the dust guide holes and the internal space of the dust bag. The connecting assembly includes an mounting component and a moving component. The dust bag is installed in a mounting hole on the mounting component, which is connected to a fixed structure on the inner wall of the dustbin. The moving component has a through hole that connects the dust guide holes and the mounting holes. The moving component moves between the mounting component and the fixed structure, allowing the mounting holes to connect or close with the dust guide holes. When the through hole connects the mounting holes and the dust guide holes, waste enters the internal space of the dust bag through the dust guide holes. When the dust bag needs to be replaced, the moving component moves to close the mounting holes and the dust guide holes, and pulls the dust bag out of the dustbin. The fixed structure includes a first sliding groove and a first locking groove. The first sliding groove is located below the first locking groove. The upper end of the moving part is provided with a first buckle that engages with the first locking groove and a second buckle that engages with the top of the mounting part. The lower part of the moving part is inserted into the first sliding groove, and the upper end of the moving part is engaged with the first locking groove and the mounting part respectively through the first and second buckles. The upper part of the moving part is covered by a mounting plate, and the lower part is inserted into the second sliding groove, restricting the deformation of the moving part in the direction perpendicular to the movement direction. During the operation of the cleaning robot, the inside of the box is a negative pressure environment. Under the negative pressure environment, both the upper and lower parts of the moving part are protected, thus making it less prone to deformation. When changing the dust bag, the moving part moves upward, first sealing the dust guide hole and the inside of the dust bag to prevent dust from flying out of the dust bag, thus improving the use efficiency of the dust bag. Then, the mounting part along with the dust bag is pulled out of the box by the moving part, avoiding the difficulty of moving the moving part caused by deformation, and making it easier to replace the dust bag. The dustbin provided by this invention, with its connection structure between the movable component, mounting component, and fixed structure, makes the movable component less prone to deformation under negative pressure. This prevents deformation of the movable component from causing it to fail to seal the dust bag during replacement, thus preventing dust from flying out and improving the dust bag's performance. Furthermore, it does not affect the movement of the movable component, making dust bag replacement easier and enhancing the user experience.

[0023] The cleaning robot provided by this invention utilizes the aforementioned dustbin, and the connection between the moving parts, the mounting parts, and the fixed structure minimizes the deformation space of the moving parts between the mounting parts and the fixed structure while ensuring that the moving parts can move normally. This makes the moving parts less prone to deformation under negative pressure, ensuring that dust will not fly out of the dust bag when it is replaced, thus improving the effectiveness of the dust bag. Furthermore, the dust bag is easier to replace, improving the user experience. Attached Figure Description

[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1-10 As shown, this embodiment provides a dustbin, including a housing 1, a connecting assembly 3, and a dust bag 2. The housing 1 has a dust guide hole 11. The connecting assembly 3 installs the dust bag 2 inside the housing 1 and is used to connect or close the dust guide hole 11 and the internal space of the dust bag 2. The connecting assembly 3 includes a mounting member 31 and a moving member 32. The mounting member 31 has a mounting hole 3111, and the dust bag 2 is installed in the mounting hole 3111. The inner wall of the housing 1 has a fixing structure, and the mounting member 31 is connected to the fixing structure. The movable component 32 is slidably disposed between the mounting component 31 and the fixed structure. The movable component 32 has a through hole 321 that connects the dust guide hole 11 and the mounting hole 3111. The movable component 32 moves within the mounting component 31, having a first upper limit position and a second lower limit position. At the first limit position, the dust bag 2 is removed, sealing the mounting hole 3111 with the dust guide hole 11. At the second limit position, the dust bag 2 is installed inside the housing 1, connecting the mounting hole 3111 with the dust guide hole 11. When the dust bag 2 needs to be replaced, the movable component 32 moves from the second limit position to the first limit position, sealing the mounting hole 3111 with the dust guide hole 11 and pulling the dust bag 2 out of the housing 1. This prevents dust from flying out of the dust guide hole 11 when replacing the dust bag 2, improving the efficiency of the dust bag 2.

[0044] In this embodiment, the opening 21 of the dust bag 2 and the mounting hole 3111 are connected as one piece by adhesive or other means.

[0045] During vacuuming, the movable part 32 moves to its lowest, second-limit position, where the through hole 321 connects the mounting hole 3111 and the dust guide hole 11. The interior of the housing 1 is a negative pressure environment. Under this negative pressure, dust and other debris from outside the housing 1 enter the dust bag 2 through the dust guide hole 11, the through hole 321, and the mounting hole 3111. In the prior art, the movable part 32 is prone to deformation under prolonged negative pressure, making it difficult to move and affecting the use, installation, and disassembly of the dust bag 2.

[0046] To solve the above problems, the fixing structure provided in this embodiment includes a first sliding groove 12 and a first locking groove 13. The first sliding groove 12 is located below the first locking groove 13. The moving part 32 includes a first side 322 and a second side 323. The first side 322 is located near the inner wall of the housing 1, and the second side 323 is located near the mounting part 31. A first buckle 3221 is provided on the first side 322, and a second buckle 3231 is provided on the second side 323. Both the first buckle 3221 and the second buckle 3231 are located at the upper end of the moving part 32. The lower part of the moving part 32 is inserted into the first sliding groove 12. The first buckle 3221 engages with the first locking groove 13, and the second buckle 3231 engages with the top end of the mounting part 31.

[0047] Specifically, two fixing members are spaced apart on the inner wall of the housing 1. The ends of the two fixing members away from the first slot 13 are fixed to the inner wall of the housing 1, and the ends near the first slot 13 form a first sliding groove 12 between the fixing members and the inner wall of the housing 1. The fixing members include a horizontal plate parallel to the inner wall of the housing 1 and a vertical plate perpendicular to the inner wall of the housing 1. One side of the vertical plate is connected to the inner wall of the housing 1, and the other side is connected to the horizontal plate. A first notch is provided on the side of the vertical plate near the inner wall of the housing 1. One end of the first notch is connected to the end of the vertical plate near the first slot 13 to form the first sliding groove 12. When the moving member 32 moves downward to the second limit position, the other end of the first notch limits the moving member 32.

[0048] A protrusion is provided on the inner wall of the housing 1, and a fixing structure is provided on the protrusion. The first slot 13 is located on the outermost side of the upper end face of the protrusion away from the inner wall of the housing 1. The cross-section of the first slot 13 is U-shaped, and the U-shaped opening faces the inner wall of the housing 1. The first buckle 3221 includes a horizontal plate and a vertical plate that are perpendicular to each other. One end of the horizontal plate is connected to the first side 322, and the other end is connected to the vertical plate. The horizontal plate is located above the vertical plate, so that when the moving member 32 moves downward, the vertical plate is engaged in the U-shaped groove of the first slot 13. The horizontal plate is used to limit the moving member 32 from moving further downward. The second buckle 3231 has a similar structure to the first buckle 3221, except that the length of the first buckle 3221 is greater than the length of the second buckle 3231. The length of the first buckle 3221 is adapted to the first slot 13 and is located at the middle position in the width direction of the moving member 32. The second buckle 3231 has two intervals, and the distance between the vertical plate of the second buckle 3231 and the second side 323 is equal to the thickness of the mounting part 31.

[0049] When the movable component 32 moves to the through hole 321 and connects the mounting hole 3111 and the dust guide hole 11, the movable component 32 is at its lowest second limit position. From top to bottom, the upper end of the movable component 32 is engaged with the first slot 13 and the mounting component 31 respectively through the first buckle 3221 and the second buckle 3231. The upper part is covered by the mounting plate 311, and the lower part is inserted into the first sliding groove 12, so that the deformation of the movable component 32 in the direction perpendicular to the movement direction is effectively limited. During the operation of the cleaning robot, the inside of the box 1 is a negative pressure environment. Under the negative pressure environment, the upper part of the movable component 32 is protected by the mounting component 31, and the lower part is protected by the first sliding groove 12, so that it is not easy to deform. When changing the dust bag 2, the movable component 32 moves upward, first sealing the dust guide hole 11 and the internal space of the dust bag 2, preventing dust from flying out of the dust bag 2, and improving the use effect of the dust bag 2. Then, the mounting part 31 and the dust bag 2 are pulled out from the box 1 by the moving part 32, which avoids the difficulty of moving the moving part 32 caused by deformation of the moving part 32 and makes it easier to replace the dust bag 2.

[0050] The dustbin provided in this embodiment, with its connection structure between the movable part 32, the mounting part 31, and the fixed structure, makes the movable part 32 less prone to deformation under negative pressure. This prevents the movable part 32 from being unable to seal the dust bag 2 when it is replaced due to deformation, thus preventing dust from flying out. Moreover, it does not affect the movement of the movable part 32, making it easier to replace the dust bag 2 and improving the user experience.

[0051] As an optional solution for the dustbin, the fixing structure also includes two guide grooves 14 arranged opposite to each other and two first snap-fit ​​parts arranged opposite to each other. The two guide grooves 14 are located below the first snap-fit ​​parts. One end of the mounting member 31 cooperates with the two guide grooves 14, and the other end snaps with the two first snap-fit ​​parts.

[0052] Specifically, two M-shaped guides are provided on the side of the protrusion away from the inner wall of the housing 1. The width of the mounting member 31 is greater than the width of the moving member 32. The two M-shaped guides are located on the outside of the two fixing members. A second notch is provided on the side of the M-shaped guides near the protrusion, and the second notch is located on the side where the two M-shaped guides are close to each other. One end of the second notch is connected to the end of the M-shaped guide near the first snap-fit ​​part to form a guide groove 14, so that the lower end of the mounting member 31 can be limited by the other end of the second notch.

[0053] The inner wall of the housing 1 is provided with two fixing blocks 15 arranged opposite each other. Each of the two fixing blocks 15 has a first snap-fit ​​part on the side that is close to each other. The first snap-fit ​​part includes a guide surface 151 and a second slot 152. The second slot 152 is located below the guide surface 151. The guide surface 151 is set as an inclined surface. The inclined surface gradually approaches the mounting member 31 from the top of the fixing block 15 towards the second slot 152. Two elastic buckles 3121 are arranged opposite each other on the mounting member 31. The elastic buckles 3121 are guided by the inclined surface to slide into the second slot 152 and snap into the second slot 152. At the same time, the end of the mounting member 31 away from the elastic buckles 3121 is inserted into the two guide grooves 14 to fix the mounting member 31.

[0054] The fixing block 15 is located on the upper end face of the protrusion. The protrusion is integrally formed with the box body 1. The fixing block 15 can also be integrally formed with the protrusion and the box body 1, or it can be a separate structure from the protrusion. The fixing block 15 is fixed to the upper end face of the protrusion by connecting structures such as screws.

[0055] When installing the dust bag 2, two guide grooves 14 are inserted into the lower ends of the mounting part 31 on both sides respectively. The elastic buckles 3121 on both sides of the upper end of the mounting part 31 slide from the guide surface 151 into the second groove 152. Then, the moving part 32 is inserted between the mounting part 31 and the protrusion. The lower part of the moving part 32 is inserted into the first sliding groove 12, and the upper part cooperates with the mounting part 31. The first buckle 3221 at the upper end of the moving part 32 engages with the first groove 13, and the second buckle 3231 engages with the top of the mounting part 31.

[0056] Furthermore, the mounting component 31 includes a mounting plate 311 and two connecting plates 312. The mounting plate 311 is disposed between the two connecting plates 312, a mounting hole 3111 is provided on the mounting plate 311, and an elastic buckle 3121 is provided on the connecting plate 312. Each of the two connecting plates 312 has a limiting plate 3122 on its adjacent side, forming a second sliding groove between the limiting plate 3122 and the mounting plate 311. The movable component 32 slides within the second sliding groove. When installing the movable component 32, the movable component 32 first passes through the second sliding groove and then enters the first sliding groove 12. Because the gap between the mounting plate 311 and the protrusion is greater than the thickness of the movable component 32, this arrangement allows the upper part of the movable component 32 to fit snugly against the mounting plate 311, restricting the deformation of the upper part of the movable component 32. The lower part of the movable component 32 is also restricted from deformation by the first sliding groove 12.

[0057] In this embodiment, a hook 3123 is provided at the lower end of the connecting plate 312. The upper width of the movable member 32 is greater than the lower width. The connection between the upper and lower parts of the movable member 32 engages with the hook 3123 to limit the displacement of the movable member 32 when the through hole 321 connects the mounting hole 3111 and the dust guide hole 11, thus providing a lower limit for the movement of the movable member 32 in the mounting member 31. Each connecting plate 312 is provided with two limiting plates 3122 from top to bottom. The four limiting plates 3122 and the mounting plate 311 form a second groove to limit the deformation of the movable member 32.

[0058] Of course, in other embodiments, each connecting plate 312 may also be provided with only one limiting plate 3122, which extends from top to bottom along the height direction of the connecting plate 312 and forms a second sliding groove with the mounting plate 311.

[0059] When replacing the dust bag 2, the moving part 32 first moves to the through hole 321 to close the mounting hole 3111 and the dust guide hole 11, and then moves the mounting part 31 along with the dust bag 2 out of the housing 1. In order to achieve the following: after the moving part 32 moves to the through hole 321 to close the mounting hole 3111 and the dust guide hole 11, the mounting part 31 along with the dust bag 2 is moved out, the bottom end of the mounting plate 311 is provided with a first limiting groove 3112, and the bottom end of the second side 323 is provided with a first limiting protrusion 3232. The first limiting protrusion 3232 can cooperate with the first limiting groove 3112 to limit the first extreme position of the movement of the moving part 32. The number of the first limiting protrusion 3232 and the corresponding first limiting groove 3112 is at least two; and / or, both sides of the first side 322 are provided with second limiting protrusions 3222, and the second limiting protrusions 3222 can abut against the bottom of the limiting plate 3122.

[0060] In this embodiment, two first limiting protrusions 3232 and two corresponding first limiting grooves 3112 are provided. The two first limiting protrusions 3232 are spaced apart at the bottom end of the second side surface 323, and the two first limiting grooves 3112 are spaced apart at the bottom end of the mounting plate 311 with the same spacing as the two first limiting protrusions 3232. The spacing between the two second limiting protrusions 3222 is equal to the length of the line connecting the centers of the two lowermost limiting plates 3122 located on the connecting plate 312. When the moving part 32 moves the mounting part 31 out of the housing 1 together, in order to ensure the stability of the connection between the moving part 32 and the mounting part 31, when the moving part 32 moves to the first limit position, the first limiting protrusion 3232 cooperates with the first limiting groove 3112, and the second limiting protrusion 3222 cooperates with the bottom of the lowest limiting plate 3122. The first limiting groove 3112 and the connecting plate 312 located at the bottom of the lowest limiting plate 3122 jointly provide the upper limit of the moving part 32 in the mounting part 31, so as to realize the snap-fit ​​fixation between the moving part 32 and the mounting part 31.

[0061] Of course, in other embodiments, only the first limiting protrusion 3232 can be provided to cooperate with the first limiting groove 3112 to limit the first extreme position of the movement of the moving member 32; or only the second limiting protrusion 3222 can be provided to abut against the bottom of the lowermost limiting plate 3122 of the connecting plate 312 to limit the first extreme position of the movement of the moving member 32.

[0062] Furthermore, such as Figure 11 and Figure 12 As shown, to ensure that dust bag 2 does not leak when removed, a first rubber ring 41 is provided inside the mounting hole 3111. The bag opening 21 of dust bag 2 is bonded to the mounting hole 3111 through the first rubber ring 41. The inner ring of the first rubber ring 41 is also provided with a first convex ring 411, which is located on the side close to the moving part 32. When the moving part 32 is inserted into the second sliding groove, the bottom of the moving part 32 compresses the first convex ring 411 and then inserts into the first sliding groove 12 and the second sliding groove. When the mounting hole 3111 and the dust guide hole 11 are connected, the first convex ring 411 can fit tightly with the through hole 321 of the moving part 32, which can guide the dust between the dust guide hole 11 and the through hole 321 into the dust bag 2 to prevent dust leakage when the dust bag 2 is removed.

[0063] Furthermore, a second rubber ring 42 is provided inside the through hole 321, and the inner diameter of the second rubber ring 42 is smaller than the inner diameter of the first rubber ring 41. The second rubber ring 42 is bonded to the through hole 321, and the inner ring of the second rubber ring 42 is provided with a second convex ring 421, which faces the dust guide hole 11 and fits tightly with the dust guide hole 11, so that the dust between the dust guide hole 11 and the through hole 321 can be guided into the dust bag 2 through the mounting hole 3111. Because the inner diameter of the second rubber ring 42 is set to be smaller than the inner diameter of the first rubber ring 41, when the moving part 32 closes the dust guide hole 11 and moves upward to close the mounting hole 3111, the dust and other debris between the through hole 321 and the mounting hole 3111 will enter the interior of the dust bag 2 and will not leak to the outside.

[0064] As an optional dustbin design, the movable component 32 has a movable handle 3223 on the side away from the mounting component 31, and a reinforcing rib 3224 connects the movable handle 3223 and the first latch 3221. The reinforcing rib 3224 enhances the connection strength between the movable handle 3223 and the first latch 3221 and the movable component 32, so as to prevent excessive upward force on the movable handle 3223, which could cause the movable handle 3223 or the first latch 3221 to disconnect from the movable component 32.

[0065] Optionally, the fixing structure also includes a limiting block 16, with the movable handle 3223 abutting against the limiting block 16 to limit the second extreme position of the movable member 32. The limiting block 16 is located on the upper end face of the protrusion and on the side of the first slot 13 near the inner wall of the housing 1. The limiting block 16 is connected to both the inner wall of the housing 1 and the upper end face of the protrusion. When installing the dust bag 2, when the bottom of the movable handle 3223 of the movable member 32 abuts against the upper surface of the limiting block 16, and at the same time the connection between the upper and lower parts of the movable member 32 abuts against the hook 3123 of the mounting member 31, it indicates that the movable member 32 has moved into place, and the through hole 321 completely connects the mounting hole 3111 and the dust guide hole 11.

[0066] In this embodiment, when installing the dust bag 2, the limiting plate 3122 is positioned towards the protruding part. The elastic buckles 3121 on both sides of the upper end of the mounting member 31 are guided and compressed by the guide surface 151, and slide into the second slot 152 to engage with the second slot 152. At the same time, the two sides of the lower end of the mounting member 31 are respectively inserted into the two guide grooves 14 to fix the mounting member 31. Then, the movable part 32 is installed. The first side of the movable part 32 faces the protrusion and is inserted into the gap between the mounting part 31 and the protrusion. The movable part 32 first passes through the second sliding groove on the mounting part 31 and then enters the first sliding groove 12. The lower part of the movable part 32 enters the first sliding groove 12. The connection between the upper and lower parts of the movable part 32 is engaged with the hook 3123 on the mounting part 31. When the movable handle 3223 abuts against the limiting block 16, the movable part 32 moves to the second limit position. The hook 3123 on the mounting part 31 and the limiting block 16 on the protrusion together realize the lower limit of the movable part 32 to ensure the accuracy of the position of the movable part 32. Thus, the through hole 321 on the movable part 32 completely connects the mounting hole 3111 and the dust guide hole 11 to ensure the smooth flow of dust and other garbage into the dust bag 2. The first buckle 3221 on the upper part of the movable part 32 engages with the first slot 13 on the upper end face of the protrusion, and the second buckle 3231 engages with the top of the mounting part 31. At this time, when the cleaning robot is working normally, dust and other garbage outside the box 1 can enter the internal space of the dust bag 2 through the dust guide hole 11, the guide hole 321 and the mounting hole 3111.

[0067] When replacing the dust bag 2, the moving part 32 is lifted upward by moving the handle 3223. The moving part 32 moves upward, and the first limiting protrusion 3232 of the second side 323 of the moving part 32 engages with the first limiting groove 3112 at the bottom of the mounting plate 311. At the same time, the second limiting protrusion 3222 of the first side 322 of the moving part 32 abuts against the bottom of the bottom limiting plate 3122 of the connecting plate 312. At this time, the first limiting groove 3112 at the bottom of the mounting plate 311 and the bottom of the bottom limiting plate 3122 of the connecting plate 312 together provide the upper limit of the movement of the moving part 32 in the mounting part 31, so as to realize the engagement and fixation of the moving part 32 and the mounting part 31. When the moving part 32 moves to the first limit position, the through hole 321 on the moving part 32 completely seals the mounting hole 3111 and the dust guide hole 11. During the process of removing the dust bag 2, the dust in the dust bag 2 will not fly out through the mounting hole 3111. Then, the handle 3223 continues to move the moving part 32 upward. At this time, the mounting part 31 moves upward with the moving part 32. The elastic buckles 3121 on both sides of the upper part of the mounting part 31 are pulled upward and disengaged from the second slot 152. They are compressed by the guide surface 151 and gradually move upward. When the elastic buckles 3121 disengage from the guide surface 151, they return to their original state. Thus, the mounting part 31 and the dust bag 2 are moved out of the box 1 together by the moving part 32, realizing the replacement of the dust bag 2.

[0068] This embodiment also provides a cleaning robot, including a cleaning body and the aforementioned dust box disposed on the cleaning body. The cleaning robot provided in this embodiment utilizes the aforementioned dust box, and the connection between the moving part 32 and the mounting part 31 and the fixed structure minimizes the deformation space of the moving part 32 between the mounting part 31 and the fixed structure while ensuring the normal movement of the moving part 32. This makes the moving part 32 less prone to deformation under negative pressure, ensuring that dust will not fly out of the dust bag 2 when it is replaced, and making the dust bag 2 easier to replace, thus improving the user experience.

[0069] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
