[0051] In related art, cleaning robots, such as sweeping robots, typically have a built-in dust box that collects garbage. To clean the garbage collected in the dust box, the user needs to detach the entire dust box from the robot and move it to a trash can. The user then opens the dust outlet of the dust box and pours the collected garbage into the trash can through the outlet to complete the cleaning of the dust box. However, the user is likely to come into direct contact with the garbage in the dust box each time they clean the dust box, resulting in a poor user experience.

[0052] Based on the above concepts and problems, the present invention proposes a dust box assembly 2 and a cleaning robot 100. It can be understood that the dust box assembly 2 is applied to the cleaning robot 100, and the cleaning robot 100 can be a sweeping robot or a sweeping-mopping robot, etc., which is not limited here.

[0053] Please refer to Figures 1 to 9 As shown, in an embodiment of the present invention, the dust box assembly 2 includes a dust suction piece 21, a dust bag 23 and a fixing structure, wherein the dust suction piece 21 is provided with a dust suction port 2111 and an outward expansion port 2131 connected to the dust suction port 2111, the dust bag 23 has an open end 231, the open end 231 is sleeved on the outward expansion port 2131, and the fixing structure is movably sleeved on the outer wall of the dust suction piece 21 for fixing the open end 231.

[0054] In this embodiment, if Figures 2 to 7 、 Figure 9As shown, the dust box assembly 2 includes a dust collection member 21, a fixing structure, and a dust bag 23. The dust box assembly 2 is detachably connected to the main structure 1 of the cleaning robot 100 via the dust collection member 21, thereby enabling the dust box assembly 2 to be detachably mounted on the main structure 1 of the cleaning robot 100. It is understood that the dust collection member 21 is provided with a dust collection port 2111 and an outwardly flared port 2131 communicating with the dust collection port 2111. In this way, when the sweeping member of the main structure 1 of the cleaning robot 100 is sweeping garbage on the ground, the dust box assembly 2 can collect and temporarily store garbage through the dust collection port 2111.

[0055] As will be appreciated, the dust bag 23 has a storage, storage, or holding space, thereby facilitating the collection and storage of garbage. To facilitate the collection of garbage into the storage, storage, or holding space of the dust bag 23, the dust bag 23 has an open end 231, allowing the storage, storage, or holding space of the dust bag 23 to communicate with the outside. In this embodiment, the open end 231 of the dust bag 23 is sleeved onto the outer flared opening 2131, thereby connecting the dust suction port 2111 to the storage, storage, or holding space of the dust bag 23 through the outer flared opening 2131. Consequently, garbage collected by the dust suction port 2111 is introduced into the storage, storage, or holding space of the dust bag 23 via the outer flared opening 2131. Furthermore, because the open end 231 of the dust bag 23 is sleeved onto the outside of the outer flared opening 2131, a seal is achieved between the outer flared opening 2131 and the open end 231, preventing garbage from falling or leaking.

[0056] Optionally, the dust bag 23 can be a garbage bag, that is, the dust bag 23 can be a disposable plastic bag. In this embodiment, the dust bag 23 is made of a material with tension or elasticity, such as plastic, sponge, etc., which is not limited here.

[0057] In this embodiment, to prevent the dust bag 23 from slipping off after being inserted through the open end 231 into the flared opening 2131, an elastic tie is provided at the open end 231, which is elastically inserted into the flared opening 2131. It will be appreciated that the open end 231 of the dust bag 23 is elastic, so that when the open end 231 of the dust bag 23 is inserted into the outside of the flared opening 2131, the inner wall of the open end 231 is tightly fitted to the outside of the flared opening 2131 due to the elasticity.

[0058] In order to further prevent the open end 231 of the dust bag 23 from separating from the outer flared opening 2131 , thereby causing problems such as garbage scattering, in this embodiment, the dust box assembly 2 is further provided with a fixing structure, so that the fixing structure is movably sleeved on the outer wall of the dust collecting member 21 .

[0059] Optionally, the fixed structure is a sliding member 22 that is movably sleeved on the outer wall of the dust collecting member 21 and is capable of moving along the outer wall of the dust collecting member 21 between the dust collecting port 2111 and the outwardly flared opening 2131; wherein the sliding member 22 moves from the dust collecting port 2111 to the outwardly flared opening 2131 to compress the open end 231. It is understood that the sliding member 22 is capable of moving along the outer wall of the dust collecting member 21 between the dust collecting port 2111 and the outwardly flared opening 2131, thereby compressing the open end 231 when the sliding member 22 moves from the dust collecting port 2111 to the outwardly flared opening 2131, thereby effectively preventing the dust bag 23 from separating from the dust collecting member 21.

[0060] The dust box assembly 2 of the present invention is provided with a dust suction port 2111 and an outer expansion port 2131 connected to the dust suction port 2111, and the open end 231 of the dust bag 23 is sleeved on the outer expansion port 2131, and the fixed structure is movably sleeved on the outer wall of the dust suction member 21 and can move along the outer wall of the dust suction member 21 between the dust suction port 2111 and the outer expansion port 2131, so that the garbage collected by the dust suction port 2111 of the dust suction member 21 is introduced into the dust bag 23 through the outer expansion port 2131 to realize garbage collection and temporary storage, and further through the fixed structure from the dust suction port 21 The dust port 2111 is moved to the outward-flaring port 2131, and the opening end 231 is pressed tightly by the fixed structure, so that the dust bag 23 is not easily separated from the dust collection part 21. In this way, when cleaning the dust box assembly 2, it is only necessary to move the fixed structure from the outward-flaring port 2131 to the dust collection port 2111 to release the opening end 231 of the dust bag 23. In this way, the dust bag 23 can be removed from the dust collection part 21, and the dust bag 23 and the garbage can be discarded together, which effectively avoids the user's contact with garbage or dust, and also makes it convenient to replace the dust bag 23, thereby improving the use convenience of the cleaning robot 100.

[0061] In one embodiment, the dust collecting member 21 includes a main body 211, an outward expansion section 213 and a stopper 212, wherein the main body 211 has a cavity 2112, one end of the main body 211 is provided with a dust collecting port 2111 connected to the cavity 2112, the outward expansion section 213 is connected to the end of the main body 211 away from the dust collecting port 2111, the outward expansion section 213 is provided with an outward expansion port 2131 connected to the cavity 2112, the outward expansion section 213 is formed with a pressure surface 2132, the open end 231 is sleeved on the outward expansion section 213 and abuts against the pressure surface 2132, the stopper 212 is provided on the outer wall of one end of the main body 211 and is arranged away from the outward expansion section 213; wherein, when the fixed structure abuts against the pressure surface 2132, the open end 231 is pressed between the fixed structure and the pressure surface 2132.

[0062] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 9As shown, in this embodiment, the main body 211 of the dust collecting member 21 is a cylindrical or frame structure having a cavity 2112. That is, both ends of the main body 211 are openings connected to the cavity 2112. The opening at one end of the main body 211 is a dust collection port 2111. One end of the main body 211 is connected to the outward expansion section 213, and the outward expansion section 213 is provided with an outward expansion port 2131. In this way, the outward expansion port 2131 is connected to the cavity 2112 through the opening at the end of the main body 211 away from the dust collection port 2111. Optionally, the main body 211, the stopper 212, and the outward expansion section 213 of the dust collecting member 21 are integrally formed.

[0063] It can be understood that by setting the stop portion 212, the stop portion 212 is arranged on the outer wall of one end of the main body 211 and is arranged adjacent to the dust suction port 2111, and a pressure surface 2132 is formed on the side of the outward expansion section 213 facing the main body 211, so that the stop portion 212, the outer wall of the main body 211 and the pressure surface 2132 of the outward expansion section 213 cooperate to form a fixed groove, and the sliding part 22 is located in the fixed groove, and is limited by the stop portion 212 and the pressure surface 2132 of the outward expansion section 213 to prevent the sliding part 22 from detaching from the fixed groove.

[0064] In this embodiment, the sliding member 22 can move along the outer wall of the main body 211 in the fixed groove, that is, move between the stop portion 212 of the sliding member 22 and the pressing surface 2132. In this way, when the sliding member 22 abuts against the pressing surface 2132, the opening end 231 is pressed between the sliding member 22 and the pressing surface 2132, thereby realizing the connection between the dust bag 23 and the dust collection member 21.

[0065] It can be understood that the sliding member 22 is an annular structure. Optionally, the sliding member 22 is a rectangular ring structure. In one embodiment, in order to facilitate the disassembly and assembly of the sliding member 22, the sliding member 22 has a detachable opening. For example, the sliding member 22 includes a first section and a second section that are detachably connected. The first section and the second section enclose a through opening, and the outer wall of the dust collecting member 21 slides and abuts against the inner wall of the through opening. That is, the first section and the second section of the sliding member 22 are connected and enclosed to form an annular structure, that is, the first section and the second section enclose to form a through opening. In this way, after the sliding member 22 is installed on the dust collecting member 21, the outer wall of the dust collecting member 21 slides and abuts against the inner wall of the through opening.

[0066] In one embodiment, the pressing surface 2132 is disposed around the outer flared opening 2131. It is understood that by disposing the pressing surface 2132 around the outer flared opening 2131, the sliding member 22 can tightly press the periphery of the opening 231 of the dust bag 23 against the pressing surface 2132, thereby improving the sealing performance of the connection between the dust bag 23 and the dust collecting member 21.

[0067] Optionally, the pressing surface 2132 is perpendicular to the outer wall of the main body 211, thereby increasing the contact area with the open end 231 of the dust bag 23. Of course, in other embodiments, the pressing surface 2132 and the outer wall of the main body 211 can also be inclined or parallel, as long as there is sufficient area to achieve compression, which is not limited here.

[0068] In one embodiment, the cross-sectional area of the outwardly flared opening 2131 gradually increases from the pressing surface 2132 to the end away from the pressing surface 2132. It is understood that the diameter of the outwardly flared section 213 gradually increases from the end adjacent to the dust collecting member 21 to the end away from the dust collecting member 21, thereby giving the outwardly flared section 213 a trumpet-shaped or flared structure. Thus, after the open end 231 of the dust bag 23 is sleeved onto the outwardly flared section 213, the elastic contraction of the open end 231 causes the open end 231 to be clamped to the outwardly flared section 213 and abut against the pressing surface 2132.

[0069] In one embodiment, the stopper 212 is disposed around the dust suction port 2111. As can be understood, this arrangement facilitates the position-limiting installation of the sliding member 22, and simultaneously the stopper 212 and the outwardly expanding section 213 of the dust suction member 21 can be utilized to achieve the position-limiting installation of the dust box assembly 2 and the main structure 1.

[0070] In one embodiment, if Figure 3 、 Figure 4 and Figure 9 As shown, the outer wall of the main body 211 is provided with a locking protrusion 2113, which is arranged adjacent to the pressing surface 2132, and the fixing structure is provided with a locking groove 221; wherein, when the fixing structure abuts the pressing surface 2132, the locking protrusion 2113 is locked in the locking groove 221.

[0071] It can be understood that by providing a latching protrusion 2113 on the outer wall of the main body 211 and providing a latching groove 221 on the sliding member 22 of the fixed structure, the latching protrusion 2113 is provided adjacent to the pressing surface 2132. In this way, when the sliding member 22 abuts against the pressing surface 2132, the latching protrusion 2113 is engaged in the latching groove 221, thereby utilizing the cooperation between the latching protrusion 2113 and the latching groove 221 to achieve the locking of the sliding member 22, thereby ensuring that the sliding member 22 continues to press the open end 231 of the dust bag 23.

[0072] Of course, in other embodiments, the outer wall of the main body 211 may be provided with the latching groove 221, and the latching protrusion 2113 may be provided with the sliding member 22, which is not limited here. It is understood that the latching engagement between the latching protrusion 2113 and the latching groove 221 can cause the latching protrusion 2113 to be disengaged from the latching groove 221 or to be engaged with the latching protrusion 2113 in the latching groove 221 under a certain external force, which is not limited here.

[0073] In one embodiment, if Figure 4 and Figure 9As shown, the dust box assembly 2 also includes a telescopic structure 24, one end of the telescopic structure 24 is connected to the stop portion 212, and the other end of the telescopic structure 24 is connected to the fixed structure; wherein, the telescopic structure 24 can drive the fixed structure to move along the outer wall of the dust collecting part 21 between the stop portion 212 and the pressing surface 2132, and push the fixed structure to press the opening end 231 against the pressing surface 2132.

[0074] It is understandable that by providing the telescopic structure 24, the telescopic structure 24 provides a certain telescopic force for the sliding member 22 of the fixed structure, thereby realizing automatic sliding of the sliding member 22 and pressing the open end 231 of the dust bag 23, thereby improving the convenience of use.

[0075] In this embodiment, the telescopic structure 24 can drive the sliding member 22 to move along the outer wall of the dust collecting member 21 between the stop portion 212 and the pressing surface 2132, and push the sliding member 22 to press the open end 231 against the pressing surface 2132. Optionally, the telescopic structure 24 is one of a spring, a telescopic rod, and a telescopic cylinder.

[0076] In one embodiment, a telescopic structure 24 can be provided on the outer wall of the main body 211 while a locking protrusion 2113 is provided. In this way, the sliding member 22 can be automatically pressed by the telescopic structure 24, and the sliding member 22 can be locked by the cooperation between the locking protrusion 2113 and the locking groove 221.

[0077] like Figures 1 to 3 As shown, the present invention further provides a cleaning robot 100, which includes a main body structure 1 and the aforementioned dust box assembly 2. The specific structure of the dust box assembly 2 is referenced to the aforementioned embodiments. Since the present cleaning robot 100 adopts all the technical solutions of all the aforementioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be detailed here.

[0078] In this embodiment, the main structure 1 is provided with a mounting base 11, which is provided with a mounting slot 111. The dust collection member 21 of the dust box assembly 2 is detachably mounted within the mounting slot 111. It will be appreciated that the main structure 1 of the cleaning robot 100 is used to mount, secure, and support the dust box assembly 2. The main structure 1 may include the outer shell, drive components, sweeping and mopping components, and other structures of the cleaning robot 100. To facilitate the installation of the dust box assembly 2, a space is provided within the main structure 1 for mounting and accommodating a dust bag 23. This allows for both the installation and securement of the dust box assembly 2 and the protection of the dust bag 23.

[0079] It is understandable that in order to facilitate cleaning of the dust box assembly 2, the dust box assembly 2 is detachably provided on the main structure 1. In this embodiment, the dust box assembly 2 can be connected by snap connection, plug-in fit, screw connection or pin connection, etc., which is not limited here.

[0080] The cleaning robot 100 of the present invention is provided with a detachable dust box assembly 2 on the main structure 1, so that the user can conveniently clean the dust box assembly 2 after using the cleaning robot 100; at the same time, the dust box assembly 2 is provided with a dust suction part 21, a sliding part 22 and a dust bag 23, so that the dust suction part 21 is provided with a dust suction port 2111 and an outward expansion port 2131 connected to the dust suction port 2111, and the open end 231 of the dust bag 23 is sleeved on the outward expansion port 2131, and the sliding part 22 is movably sleeved on the outer wall of the dust suction part 21 and can move along the outer wall of the dust suction part 21 between the dust suction port 2111 and the outward expansion port 2131, so that the garbage collected by the dust suction port 2111 of the dust suction part 21 is The dust bag 23 is introduced into the dust bag 23 through the outer expansion opening 2131 to realize garbage collection and temporary storage, and is further moved from the dust suction port 2111 to the outer expansion opening 2131 by the sliding member 22, and the open end 231 is pressed by the sliding member 22, so that the dust bag 23 is not easily separated from the dust suction member 21. In this way, when cleaning the dust box assembly 2, it is only necessary to move the sliding member 22 from the outer expansion opening 2131 to the dust suction port 2111 to release the open end 231 of the dust bag 23. In this way, the dust bag 23 can be removed from the dust suction member 21, and the dust bag 23 and the garbage can be discarded together, effectively avoiding the user's contact with garbage or dust, and also making it convenient to replace the dust bag 23, thereby improving the use convenience of the cleaning robot 100.

[0081] In one embodiment, if Figures 2 to 8 As shown, the main structure 1 is provided with a mounting base 11 , and the mounting base 11 is provided with a mounting groove 111 , and the dust collecting member 21 is detachably mounted in the mounting groove 111 , so that the mounting base 11 pushes the sliding member 22 to abut against the pressing surface 2132 to press the opening end 231 .

[0082] In this embodiment, a mounting base 11 is provided inside the main structure 1, thereby utilizing the mounting base 11 to achieve detachable installation of the dust box assembly 2. It is understandable that the mounting base 11 can be integrally provided on the main structure 1 by welding or an integrally formed structure, which can improve the connection strength and stability between the mounting base 11 and the main structure 1, thereby enabling stable installation of the dust box assembly 2. Of course, in other embodiments, the mounting base 11 can also be connected to the main structure 1 by a detachable connection method, such as a snap connection, plug-in fit, screw connection, or pin connection, etc., so as to achieve convenient assembly and disassembly of the mounting base 11, which is not limited here.

[0083] In one embodiment, if Figures 2 to 8As shown, the mounting base 11 includes a bottom plate 112 and side plates 113 spaced apart from the bottom plate 112. The side plates 113 and the bottom plate 112 enclose a mounting groove 111. When the dust collecting member 21 is installed in the mounting groove 111, the two sides of each side plate 113 respectively engage with the fixed structure of the dust collecting member 21 and the dust box assembly 2. In this embodiment, the two side plates 113 and the bottom plate 112 enclose the mounting groove 111.

[0084] In this embodiment, the width of each side plate 113 of the mounting base 11 gradually decreases from the end adjacent to the bottom plate 112 to the end distal to the bottom plate 112. The distance between the stopper 212 and the pressing surface 2132 also gradually decreases from the side adjacent to the bottom plate 112 to the side distal to the bottom plate 112. When the dust collector 21 is installed in the mounting slot 111, the two sides of each side plate 113 respectively engage the stopper 212 and the sliding member 22 in a limiting manner.

[0085] It is understood that the mounting groove 111 of the mounting base 11 is configured as a U-shaped groove, which facilitates the detachable installation of the dust collecting member 21 of the dust box assembly 2. In this embodiment, the mounting base 11 includes a bottom plate 112 and two side plates 113. The two side plates 113 are spaced apart and arranged in parallel on the same side of the bottom plate 112, so that the two side plates 113 and the bottom plate 112 enclose the mounting groove 111.

[0086] In this embodiment, the side panel 113 is provided with a wedge-shaped or triangular structure, and the distance between the stop portion 212 and the pressing surface 2132 of the dust collecting member 21 is set to gradually decrease from the side adjacent to the bottom plate 112 to the side away from the bottom plate 112. Thus, when the dust collecting member 21 is installed in the mounting groove 111, the side panel 113 is limited to the annular groove formed by the stop portion 212 and the pressing surface 2132 on the dust collecting member 21. In this way, the driving force for the movement of the sliding member 22 is achieved by changing the width of the side panel 113.

[0087] It is understood that the width of the side panels 113 gradually decreases from the end adjacent to the bottom panel 112 to the end distal to the bottom panel 112. In this embodiment, when the dust collecting member 21 is installed in the mounting slot 111, both sides of each side panel 113 respectively engage with the stopper 212 and the sliding member 22, thereby causing the sliding member 22 to engage with the pressing surface 2132 and press the open end 231 of the dust bag 23.

[0088] In one embodiment, each side plate 113 is provided with a first sliding surface 114 on the side facing the dust collecting member 21, and the dust collecting member 21 is provided with two second sliding surfaces 2121; each first sliding surface 114 slides along a second sliding surface 2121, so that when the side plate 113 is limited between the dust collecting member 21 and the fixed structure, the side plate 113 pushes the fixed structure to move and abuts against the pressing surface 2132 of the dust collecting member 21 to press the open end 231 of the dust bag 23.

[0089] In this embodiment, if Figures 5 to 8 As shown, each side plate 113 is provided with a first sliding surface 114 on the side facing the stop portion 212, and the stop portion 212 is provided with two second sliding surfaces 2121; each first sliding surface 114 slides along a second sliding surface 2121, so that when the side plate 113 is limited between the stop portion 212 and the sliding member 22, the side plate 113 pushes the sliding member 22 to move and abuts against the pressing surface 2132 to press the open end 231.

[0090] It is understood that the side of the side plate 113 that contacts the stopper 212 is provided with a first sliding surface 114, and the side of the side plate 113 that contacts the sliding member 22 is adapted to the outer wall of the sliding member 22. In this embodiment, the first sliding surface 114 and the second sliding surface 2121 are provided to facilitate installation of the dust collecting member 21 in the installation groove 111, and the first sliding surface 114 and the second sliding surface 2121 are used to slide together to achieve guidance.

[0091] In this embodiment, the engagement structure of the protrusion 2113 and the engagement groove 221 of the dust box assembly 2 can be provided simultaneously with the telescopic structure 24, or can be provided separately. Figure 4 and Figure 9 As shown, the matching structure of the protrusion 2113 and the slot 221 of the dust box assembly 2 and the telescopic structure 24 can be set at the same time as the structure of the mounting base 11. Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, the engagement structure of the protrusion 2113 and the slot 221 of the dust box assembly 2 is provided simultaneously with the structure of the mounting base 11. In other embodiments, the telescopic structure 24 of the dust box assembly 2 can also be provided simultaneously with the structure of the mounting base 11, which is not limited here.

[0092] In one embodiment, if Figures 6 to 8 As shown, each first sliding surface 114 is provided with a snap-fitting protrusion 115, which is arranged adjacent to the bottom plate 112, and each second sliding surface 2121 is provided with a snap-fitting groove 2122; when the dust collecting part 21 is installed in the mounting groove 111 and abuts against the bottom plate 112 to limit the position, the snap-fitting protrusion 115 is snap-fitted into the snap-fitting groove 2122.

[0093] It is understood that by providing the engaging protrusion 115 and the engaging groove 2122, the dust collecting member 21 is locked when it is installed in the installation groove 111. In this embodiment, a positioning groove is provided at one end of the side plate 113 connected to the bottom plate 112. That is, after the dust collecting member 21 is installed in place, the stopper 212 of the dust collecting member 21 is limited to the positioning groove and is engaged in the engaging groove 2122 by the engaging protrusion 115, further locking the dust collecting member 21.

[0094] In this embodiment, the snap-fitting cooperation between the snap-fitting protrusion 115 and the snap-fitting groove 2122 can enable the snap-fitting protrusion 115 to be snapped into the snap-fitting groove 2122 or the snap-fitting protrusion 115 to be detached from the snap-fitting groove 2122 under a certain external force, that is, the snap-fitting protrusion 115 can be set to a structure with elastic deformation, which is not limited here.

[0095] In one embodiment, if Figures 2 to 8 As shown, each side plate 113 is provided with a deformation through hole 116, which corresponds to the snap-fit protrusion 115 and passes through the side plate 113. The deformation through hole 116 is arranged in a strip shape, and the length of the deformation through hole 116 is greater than the length of the snap-fit protrusion 115 on the first sliding surface 114.

[0096] It can be understood that by setting the deformation through hole 116, the deformation through hole 116 is set to pass through the side plate 113 and is set corresponding to the clamping protrusion 115, so that the deformation through hole 116 is used to provide a deformation space for the deformation of the clamping protrusion 115. In this way, when the dust collector 21 is installed in the installation groove 111, the clamping protrusion 115 is clamped in the clamping groove 2122. When a certain external force is applied, the clamping protrusion 115 is detached from the clamping groove 2122.

[0097] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
