[0019] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be described in more detail below with reference to the accompanying drawings, but obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments of the present disclosure, other embodiments obtained by those skilled in the art without creative labor are all included in the protection scope of the present disclosure.

[0020] It should be noted that the terms "comprises," "has," or any other variation thereof are intended to cover a non-exclusive inclusion, such that a product or device that includes a set of elements includes not only those elements but also other elements not expressly listed or inherent in such product or device. Unless further limited, an element defined with the phrase "including one of" does not exclude the presence of other elements of the same type in the product or device of said element.

[0021] The automatic cleaning device usually includes a dust box for collecting dirt, and when the automatic cleaning device performs a cleaning task, dirt in the working area, such as dust, scraps of paper, etc., is collected in the dust box. When a lot of dirt is collected in the dust box, a user takes out the dust box in the automatic cleaning device, opens the dust box, and cleans the dirt therein. When cleaning the dirt in the dust box, it is usually necessary to take out the filter net assembly in the dust box and clean the dirt.

[0022] The present disclosure provides a dust box for an automatic cleaning device, such as a robot vacuum cleaner, comprising: a dust box body having a bottom wall and at least one side wall disposed around an edge of the bottom wall, the side wall extending away from the bottom wall, the bottom wall and the side wall enclosing a storage space; and a dust box cover pivotally connected to a first side wall of the dust box body and configured to cover a top of the storage space, wherein a second side wall of the dust box is provided with an elastic sheet assembly elastically pivotally connected to the second side wall, the elastic sheet assembly being rotatable relative to the second side wall about a first axis extending along a first direction, the first direction being parallel to the bottom wall, and the dust box cover has a protrusion configured to cooperate with the elastic sheet assembly in the process of the dust box cover covering the top of the storage space.

[0023] By adopting such a dust box, it is possible to avoid forgetting to install the filter net assembly when the dust box is reloaded into the automatic cleaning device after cleaning the dust box. Specifically, according to the dust box of the present disclosure, only after the user loads the filter net assembly into the storage structure in the dust box body, the dust box cover can cover the top of the storage space and engage with the dust box body. If the user forgets to load the filter net assembly, the dust box cover cannot engage with the dust box body, thereby reminding the user to avoid forgetting to install the filter net assembly.

[0024] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0025] Fig. 1 is a structural schematic diagram of a dust box provided by some embodiments of the present disclosure, Fig. 2 is a structural schematic diagram of a dust box cover of the dust box in Fig. 1, and Fig. 3 is a structural schematic diagram of a dust box body of the dust box in Fig. 1. As shown in Figs. 1-3, the dust box 100 includes a dust box body 10 and a dust box cover 20. The dust box body 10 has a bottom wall 15 and at least one side wall provided around the edge of the bottom wall 10, the side wall extends from the bottom wall 15 away from the bottom wall 15, the bottom wall 15 and the side wall surround a storage space 30, and the storage space 30 is configured to store dust and a filter net assembly.

[0026] The dust box cover 20 is pivotally connected to the first side wall 11 of the dust box body 10 and is configured to cover the top of the storage space 30, the dust box body 10 is substantially rectangular in shape and its orthogonal projection on the plane in which the bottom wall 15 is located is substantially rectangular, the first side wall 11 of the dust box body 10 is, for example, one short side wall of the dust box body 10, and in this specification, the short side wall means the side wall corresponding to the short side of the rectangular projection of the rectangular parallelepiped, whereas in this specification, the long side wall means the side wall corresponding to the long side of the rectangular projection of the rectangular parallelepiped. The dust box cover 20 can rotate around a pivot axis relative to the first side wall 11 of the dust box body 10, and the dust box 100 can be switched between an open state and a closed state.

[0027] The dust box cover 20 completely covers the top of the storage space, and when it is engaged with the dust box body 10 by a snap-fit ​​structure, the dust box 100 is in a closed state. When the dust box cover 20 rotates to expose at least a part of the storage space 30, the dust box 100 is in an open state. The dust box 100 can be switched between a closed state and an open state to facilitate operations such as cleaning up garbage in the dust box 100, cleaning or replacing the filter mesh structure, etc.

[0028] The dust box 10 has an elastic sheet assembly 40 on a second side wall 12, which is elastically pivotally connected to the second side wall 12, and the elastic sheet assembly 40 is rotatable about a first axis A1 extending along a first direction X relative to the second side wall 12, the first direction X being parallel to the bottom wall 15, and the first direction X being further parallel to the extension direction of the second side wall 12.

[0029] The dust box cover 20 includes a protrusion 21 that cooperates with the elastic sheet assembly 40 when the dust box cover 20 covers the top of the accommodating space 30. The protrusion 21 is located on a side surface facing the dust box body 10 when the dust box cover 20 is engaged with the dust box body 10, and extends from the body of the dust box cover 20 away from the dust box cover 20.

[0030] By adopting such a dust box, it is possible to avoid forgetting to install the filter net assembly when the dust box is reloaded into the automatic cleaning device after the dust box is cleaned. Specifically, by adopting the dust box of the present disclosure, the dust box cover can cover the top of the accommodating space and engage with the dust box body only after the user inserts the filter net assembly into the accommodating structure in the dust box body. If the user forgets to insert the filter net assembly, the elastic sheet assembly abuts against the protrusion on the dust box cover during the engagement process of the dust box cover, and the dust box cover cannot engage with the dust box body, thereby reminding the user to avoid forgetting to install the filter net assembly.

[0031] 4 is a partially enlarged schematic view of FIG. 3, specifically, FIG. 4 is an enlarged schematic view of region B in FIG. 3. As shown in FIGS. 1 to 4, the elastic sheet assembly 40 includes a rotating member 41 and an elastic member 42, the rotating member 41 is rotatable between a first position and a second position around the first axis A1 relative to the second side wall 12, and the elastic member 42 biases the rotating member 41 to the first position. The rotating member 41 has a first portion 411 and a second portion 412, the boundary between the first portion 411 and the second portion 412 is parallel to the first axis A1, and the first portion 411 and the second portion 412 form a predetermined angle. The cross section of the rotating member 41 perpendicular to the first axis A1 is, for example, substantially "L" shaped.

[0032] In response to the rotation member 41 being at the first position, a first end 4111 of the first part 411 remote from the bottom wall 15 is pressed against the second side wall 12, specifically, against the inner wall of the second side wall 12, and at this time, in the process of the dust box cover 20 being engaged with the dust box body 10, the protrusion 21 on the dust box cover 20 is pressed against the first end 4111 of the first part 411, and the dust box cover 20 cannot be engaged with the dust box body 10, so that the user can be reminded to avoid forgetting to install the filter net assembly. In response to the rotation member 41 being at the second position, there is a gap G between the first end 4111 of the first part 411 and the second side wall 12, and the gap G is configured to accommodate the protrusion 21 so that the dust box cover 20 completely covers the top of the accommodating space 30, and at this time, the dust box cover 20 is completely engaged with the dust box body 10.

[0033] 5 is a structural schematic diagram of a filter net assembly provided by some embodiments of the present disclosure, and FIG. 6 is a structural schematic diagram of a filter net assembly provided by some embodiments of the present disclosure when disposed in a dust box body. As shown in FIGS. 1 to 6, the dust box 100 further includes a filter net assembly 50, which is configured to be removably disposed in the storage space 30. The filter net assembly 50 is, for example, a substantially rectangular plate. A step structure configured to support the filter net assembly 50 is provided on the inner wall of the side wall of the dust box body 10, and the storage space 30 is divided into a first storage space 31 and a second storage space 32, and the first storage space 31 is located on the side away from the bottom wall 15 of the second storage space 32, and the first storage space 31 is used to store the filter net assembly 50, and the second storage space 32 is used to store the garbage collected by the dust box 100.

[0034] 5 and 6, a first protrusion 511 is provided on a first side 51 of the filtration net assembly 50, and the first protrusion 511 is configured to cooperate with the elastic sheet assembly 40 when the filtration net assembly 50 is disposed in the first accommodating space 31. Specifically, when the filtration net assembly 50 is disposed in the first accommodating space 31, the second portion 412 of the rotating member 41 is pressed by the first protrusion 511, causing the rotating member 41 to rotate from the first position to the second position. When the filtration net assembly 50 is completely disposed in the first accommodating space 31, the rotating member 41 is in the second position. At this time, there is a gap G between the first end 4111 of the first part 411 of the rotating member 41 and the second side wall 12, and in the process of the dust box cover 20 being engaged with the dust box body 10, the protrusion 21 on the dust box cover 20 can be accommodated in the gap G, and the dust box cover 20 can be completely engaged with the dust box body 10.

[0035] If the filter mesh assembly 50 is forgotten to be installed, for example, when the user opens the dust box 100, removes the filter mesh assembly 50, cleans the garbage in the dust box 100, and then forgets to re-install the filter mesh assembly 50 into the first accommodating space 31, under the elastic biasing action of the elastic member 42, the rotating member 41 is in the first position, i.e., the first end 4111 of the first part 411 of the rotating member 41, which is away from the bottom wall 15, is pressed against the second side wall 12. At this time, in the process of the dust box cover 20 engaging with the dust box body 10, the protrusion 21 on the dust box cover 20 is pressed against the first end 4111 of the first part 411, so that the dust box cover 20 cannot engage with the dust box body 10, thereby notifying the user to avoid forgetting to install the filter mesh assembly.

[0036] In some embodiments, a handle structure 55 is provided on one side, such as the upper surface, of the filtration mesh assembly 50 at a middle position, allowing a user to easily grasp the filtration mesh assembly 50 and remove the filtration mesh assembly 50 from the dust box 100 or reload the filtration mesh assembly into the dust box 100.

[0038] With the filtration mesh assembly 50 configured in this manner, the user does not need to pay excessive attention to the alignment issue of the installation of the filtration mesh assembly when reloading the filtration mesh assembly 50 into the dust box 100. When the filtration mesh assembly 50 is reloaded into the first accommodating space 31, one of the first convex portion 511 and the second convex portion 521 presses the second part 412 of the rotating member 41, so that the rotating member 41 is in the second position and the dust box cover 20 is fully engaged with the dust box body 10.

[0039] 3, a groove 121 is provided on the second side wall 12, and the elastic sheet assembly 40 is provided in the groove 121. In this way, the overall structure of the dust box can be made relatively compact, the elastic sheet assembly 40 is prevented from excessively extending from the second side wall 12 into the accommodating space 30, the filter net assembly 50 has a substantially rectangular plate-like structure, and the filter net assembly can be easily manufactured.

[0040] 1-3 , the second sidewall 12 is adjacent to the first sidewall 11, and the elastic sheet assembly 40 is disposed on a portion of the second sidewall 12 close to the first sidewall 11. However, the present disclosure is not limited in this respect, and the elastic sheet assembly 40 may be disposed on a portion of the second sidewall 12 away from the first sidewall 11.

[0041] In other embodiments, the elastic sheet assembly 40 may be provided on the side wall opposite the first side wall 11, and this disclosure is not particularly limited thereto, as long as the dust box cover 20 and the elastic sheet assembly 40 are positioned in correspondence with each other and cooperate with each other in the process in which the dust box cover covers the top of the storage space.
