Description
TECHNICAL AREA The present application relates to the technical field of accessories for cleaning devices and provides in particular an integrated dust container-water tank assembly as well as a cleaning device. STATE OF THE ART Conventional robotic vacuum cleaners feature a wide variety of dust container assemblies. Some models have separate dust containers and water tanks, resulting in a relatively low level of integration. Furthermore, the dust container's air duct is often long and the filter area small, leading to low efficiency in vacuuming up dirt such as dust and particles. CONTENT OF THE PRESENT APPLICATION The aim of the present application is to provide an integrated dust container-water tank assembly and a cleaning device to solve the problems of low suction efficiency and low integration level of conventional dust containers. To achieve the above objective, the following technical solution is used: In a first aspect, an integrated dust container-water tank assembly is provided according to embodiments of the present application, comprising: a housing having a separate dust container cavity and a water tank cavity, wherein the housing has an upper end face and at least four side wall surfaces connected to the upper end face; and a filter assembly arranged in the dust container cavity, the plane in which the filter assembly is located being parallel to the upper end face. One of the two adjacent side wall surfaces has an air inlet, and the other has an air intake opening. An airflow enters the dust container cavity through the air inlet, flows through the filter assembly, and is then discharged through the air intake opening. Advantageous effects of the present application: The integrated dust container-water tank assembly provided by the present application has an integrated design, meaning that the dust container cavity and the water tank cavity are formed as a single unit within the housing. This effectively improves space utilization. During maintenance work by the user, dirt in the dust container cavity can be cleaned, and the water in the water tank cavity can be changed or refilled simultaneously. Furthermore, the air inlet and the air intake opening are located on adjacent side wall surfaces, which shortens the air duct and reduces airflow loss during transit. Additionally, the filter assembly is arranged parallel to the upper end face of the housing, so that its surface is perpendicular to the direction of gravity. Dust and dirt are briefly held against the filter surface by the airflow.As soon as the power source at the air intake is switched off, dust and dirt fall into the dust container cavity under the influence of gravity. This can improve the significantly decreasing air permeability of the filter assembly during long-term use and reduce the maintenance frequency for the user. The integrated dust container-water tank assembly provided by the present application is characterized by a higher degree of integration and a significantly improved suction efficiency. In some embodiments, the air passage area of the filter assembly is larger than the air passage area of the air inlet; and / or the air passage area of the filter assembly is larger than the air passage area of the air intake opening. By applying the above technical solution, the flow efficiency of the airflow through the filter assembly can be effectively improved. In some embodiments, the dust container cavity has an upper separating cavity and a lower separating cavity connected to it. The housing has a mounting opening for connecting the upper and lower partitions. The filter assembly is located at this mounting opening. The air inlet is connected to the lower partition, and the air intake opening is connected to the upper partition. By applying the above technical solution, air enters the lower separation cavity through the air inlet, flows through the filter assembly, reaches the upper separation cavity, and is then discharged through the air intake opening. Dust and dirt adhere to the surface of the filter assembly and can be collected by gravity in the lower separation cavity. In some embodiments, the housing comprises a lower housing and an upper housing mounted on top of it. An air inlet is formed on a side wall of the lower housing, and an air intake opening is formed on a side wall of the upper housing. Furthermore, a mounting opening is formed in the upper housing. By applying the above technical solution, the housing is divided into an upper and lower housing, with the filter assembly located in the upper housing. This facilitates subsequent installation, replacement, and cleaning of the filter assembly, as well as subsequent cleaning of the housing. In some embodiments, the upper housing comprises a housing body, a dust container lid mounted thereon, and a filter mis-installation protection device. The filter mis-installation protection device includes a pivoting element that is rotatably connected to the inner wall of the upper partition cavity. The pivoting element interferes with the dust container lid when the filter assembly is not inserted into the housing and the dust container lid is placed on top, preventing it from closing. The filter assembly interferes with the pivoting element, and this interference between the pivoting element and the dust container lid is eliminated when the filter assembly is inserted into the housing and the dust container lid is placed on top, allowing the dust container lid to close the housing. By implementing the above technical solution, the dust container lid cannot be closed with the housing until the filter assembly is inserted. This serves as a reminder to the user to install the filter assembly. The dust container lid can only be closed once the filter assembly is in place. This design prevents both missed and incorrect installation of the filter assembly, thus improving the user experience. In some embodiments, the upper housing further comprises a button assembly that is movably connected to the housing body. A first mounting groove and a second mounting groove are formed on the housing body, located on opposite sides of the dust container lid. The button assembly is movably arranged in the first mounting groove, its direction of movement being parallel to the direction of separation between the first and second mounting grooves. By applying the above technical solution, a force directed in the direction of the distance between the first mounting groove and the second mounting groove is exerted on the key assembly in order to actuate the key assembly, thereby making it easy to remove the housing from the main unit of the cleaning device, especially if there is no point of attack on the main unit. In some embodiments, the key assembly comprises a key body and an elastic element. A locking arm is arranged on opposite sides of the key body. A locking groove for receiving the locking arm is formed on the wall of the first mounting groove. One end of the elastic element is connected to the lower end of the key body, and the other end is connected to the wall of the first mounting groove. A limiting projection is provided at the upper end of the key body, opposite the elastic element. By applying the above technical solution, the elastic element is constantly compressed, thus keeping the key body continuously pressed down. Simultaneously, the locking arm slides in the locking groove, so that the key body moves exclusively within the first mounting groove. During the movement of the key body in the first mounting groove, the limiting projection engages with or disengages from the inner wall of the main unit of the cleaning device, thereby achieving a limitation or release of the housing relative to the main unit. In some embodiments, a dust outlet opening is formed on a side wall surface of the lower housing, opposite the air inlet. The housing includes a dust container opening cover for closing the dust outlet opening; or the housing includes a dust collection hinged assembly at the dust outlet opening. By applying the above technical solution, the user can position either the dust container opening cover or the dust collection flap assembly at the dust outlet, depending on practical requirements. The dust container opening cover is used for a non-self-vacuuming integrated dust container / water tank assembly, where manual cleaning of the dust container cavity is necessary. In contrast, positioning the dust collection flap assembly at the dust outlet allows connection to a dust collection container or cleaning station, thus fulfilling the requirement for automatic cleaning of the dust container cavity. In some embodiments, the water tank cavity is arranged opposite the air intake opening. A water outlet connection assembly is provided on the lower inner wall of the water tank cavity. By applying the above technical solution, the water outlet connection assembly is connected to the main unit of the cleaning device. When the integrated dust container / water tank assembly is removed from the main unit, the water outlet hole on the integrated dust container / water tank assembly is closed. This facilitates disassembly from the main unit and simplifies cleaning. In a second aspect, embodiments of the present application further provide a cleaning device comprising a main unit and the integrated dust container-water tank assembly described above. Advantageous effects of the present application: Due to the aforementioned integrated dust container-water tank assembly, the cleaning device of the application has a higher suction efficiency and can be miniaturized more easily.

DETAILED DESCRIPTION The embodiments of the present application are described in detail below. Examples are shown in the accompanying drawings. Reference numerals that are identical or similar throughout denote identical or similar components or components with the same or similar function. The embodiments described below with reference to the drawings are exemplary and serve only to illustrate the application, not to limit it. In the description of the present application, it must be understood that the terms "length", "width", "top", "bottom", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside", as well as similar expressions indicating an orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings. These terms serve only to better describe the present application and to simplify its presentation, without indicating or suggesting that the device or element in question must have a specific orientation, be assembled in a specific orientation, or be operated in a specific orientation. Therefore, they are not to be interpreted as limiting the present application. Furthermore, the terms “first” and “second” serve purely descriptive purposes and are not to be interpreted as indicating or implying a relative meaning or as an implicit indication of the number of technical features designated. Thus, a feature defined by “first” or “second” may expressly or implicitly comprise one or more such features. In the description of this application, the term “several” refers to two or more, unless expressly and specifically stated otherwise. In this application, the terms "assemble," "connect," "attach," "fasten," and similar concepts are to be understood in their broadest sense, unless expressly defined and specified otherwise. For example, they may refer to a permanent connection, a detachable connection, or a unified design; they may refer to a mechanical or an electrical connection; they may refer to a direct connection or an indirect connection via an intermediate element; they may also refer to an internal connection between two elements or an interaction between two elements. For a person skilled in the art, the above terms may be interpreted more specifically depending on the particular circumstances of this application. Comparable robotic vacuum cleaners come in a variety of designs for their dustbins. Among these are models where the dustbin and water tank are separate, resulting in a relatively low level of integration. Furthermore, the dustbin's air duct design is elongated and the filter area is small, leading to low suction efficiency for dirt such as dust and particles. Against this background, the present application provides an integrated dust container-water tank assembly that employs an overall integrated design. This means that the dust container cavity and the water tank cavity are formed as a single unit within the housing, significantly improving space utilization efficiency. During maintenance, the user can clean the dust container while simultaneously changing or adding water to the water tank cavity. Furthermore, the air inlet and air intake are located on adjacent side wall surfaces, resulting in a shorter air duct and reduced airflow loss. The filter assembly is positioned parallel to the upper end face of the housing, ensuring that the filter surface of the assembly is perpendicular to the direction of gravity.Dust and dirt adhere to the surface of the filter assembly only briefly when carried along by the airflow. As soon as the power source at the air intake is switched off, dust, dirt, and the like fall into the dust container cavity under the influence of gravity. This can improve the problem of drastically decreasing air permeability of the filter assembly during long-term use and, to some extent, reduce the maintenance frequency for the user. With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 to Fig. 16, a first aspect of the embodiments of the present application provides an integrated dust container-water tank assembly 100, comprising a housing 10 and a filter assembly 20. The housing 10 has a separate dust container cavity 10a and a water tank cavity 10b. The housing 10 has an upper end face 10c and at least four side wall surfaces 10d adjoining the upper end face 10c. The filter assembly 20 is arranged in the dust container cavity 10a, with the plane in which the filter assembly 20 is located running parallel to the upper end face 10c. An air inlet 10e is formed on one of the two adjacent side wall surfaces 10d and an air intake opening 10f on the other. An airflow enters the dust container cavity 10a through the air inlet 10e, flows through the filter assembly 20, and is then discharged through the air intake opening 10f. It is understood that the dust container cavity 10a serves to collect dust and solid particles, while the water tank cavity 10b is intended to hold clean water for mopping the floor by the cleaning device. The dust container cavity 10a and the water tank cavity 10b are separate from each other and do not communicate with each other. Since the dust container cavity 10a and the water tank cavity 10b are manufactured by injection molding the housing 10 as a single piece, they can share a common side wall, making the housing 10 more compact overall. The housing 10 preferably has a cube-shaped structure, with the upper end face 10c being the surface facing the user, i.e., the surface facing away from the floor to be cleaned. The side wall surfaces 10d are the circumferential surfaces of the housing 10; they can be arranged in pairs opposite each other or not opposite each other. If the filter assembly 20 is arranged parallel or substantially parallel within the dust container cavity 10a, the plane in which the filter assembly 20 is located is perpendicular or substantially perpendicular to the direction of gravity during operation. The air inlet 10e serves to connect to the central brush assembly of the cleaning device, through which dust and particles enter the dust container cavity 10a. The air intake opening 10f serves to connect to the suction assembly of the cleaning device in order to create a negative pressure in the dust container cavity 10a. By arranging the air inlet 10e and the air intake opening 10f on both adjacent side wall surfaces 10d, the length of the air duct can be shortened to a certain extent. The integrated dust container-water tank assembly 100 of the application uses an integrated design in which the dust container cavity 10a and the water tank cavity 10b are formed integrally with the housing 10. This effectively improves space utilization. When the user performs maintenance, they can clean dirt from the dust container cavity 10a and simultaneously change or refill the water in the water tank cavity 10b. Since the air inlet 10e and the air intake opening 10f are located on adjacent side wall surfaces 10d, the air duct is shorter and the flow loss is reduced. In addition, the filter assembly 20 is arranged parallel to the upper end face 10c of the housing 10, so that its surface is perpendicular to the direction of gravity. Dust and dirt are carried along by the airflow and adhere briefly to the filter surface.As soon as the power source at the air intake opening 10f is switched off, dust and dirt fall into the dust container cavity 10a under the influence of gravity. This improves the problem of a drastically decreasing air permeability of the filter assembly 20 during long-term use and reduces the maintenance frequency for the user to some extent. The integrated dust container / water tank assembly 100 of the application is characterized by a higher degree of integration and significantly improved suction performance. In some embodiments, the air passage area of the filter assembly 20 is larger than the air passage area of the air inlet 10e; and / or the air passage area of the filter assembly 20 is larger than the air passage area of the air intake opening 10f. It is understood that the air passage area refers to the area through which the airflow can pass. Since the filter assembly 20 is arranged parallel to the upper end face 10c, its air passage area can be located close to the area of the upper end face 10c. Therefore, by appropriately reducing the dimensions of the air inlet 10e and the air intake opening 10f, the air passage area of the filter assembly 20 can be made larger than that of the air inlet 10e or the air intake opening 10f, thereby effectively increasing the flow velocity through the filter assembly 20. For example, the air passage area of the filter assembly 20 is larger than that of the air inlet 10e and larger than that of the air intake opening 10f, in order to further improve the efficiency of the airflow through the filter assembly 20. With reference to Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 to 16, the dust container cavity 10a has, in some embodiments, an upper partition cavity 10a1 and a lower partition cavity 10a2 connected to it. A mounting opening 10a3 is formed in the housing 10 for connecting the upper partition cavity 10a1 and the lower partition cavity 10a2. The filter assembly 20 is arranged at the mounting opening 10a3. The air inlet 10e is connected to the lower partition cavity 10a2, and the air intake opening 10f is connected to the upper partition cavity 10a1. It is understood that when installed in the mounting opening 10a3, the filter assembly 20 separates the upper separation cavity 10a1 and the lower separation cavity 10a2 from each other. The airflow passes through the filter assembly 20 from bottom to top. This allows air to enter the lower separation cavity 10a2 through the air inlet 10e, flow through the filter assembly 20, enter the upper separation cavity 10a1, and is then discharged through the air intake opening 10f. Dust and dirt adhere to the surface of the filter assembly 20 and can be collected by gravity in the lower separation cavity 10a2. With reference to Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 to 16, the housing 10, in some embodiments, comprises a lower housing 11 and an upper housing 12 mounted thereon. An air inlet 10e is formed on a side wall surface 10d of the lower housing 11, and an air intake opening 10f is formed on a side wall surface 10d of the upper housing 12. Furthermore, a mounting opening 10a3 is formed in the upper housing 12. It is understood that the division of the housing 10 into upper housing 12 and lower housing 11, as well as the arrangement of the filter assembly 20 on the upper housing 12, facilitates the subsequent installation, replacement and cleaning of the filter assembly 20 and the housing 10. With reference to Figs. 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 to 20, the upper housing 12, in some embodiments, comprises a housing body 121, a dust container cover 122 mounted thereon, and a filter incorrect installation protection device 13. The filter incorrect installation protection device 13 comprises a pivoting element 131, which is rotatably connected to the inner wall of the upper partition cavity 10a1. If the filter assembly 20 is not inserted into the housing body 121 and the dust container cover 122 is placed on the housing body 121, the pivoting element 131 interferes with the dust container cover 122, preventing the dust container cover 122 from being closed with the housing body 121. If the filter assembly 20 is inserted into the housing body 121 and the dust container cover 122 is placed on it, the filter assembly 20 interferes with the pivoting element 131, thereby eliminating the interference between the pivoting element 131 and the dust container cover 122, allowing the dust container cover 122 to be closed with the housing body 121. It is understood that the pivoting element 131 of the filter misassembly protection device 13 is rotatably connected to the inner wall of the upper partition cavity 10a1 and can pivot about an axis during operation to ensure interference between the pivoting element 131 and the dust container lid 122. The pivoting element 131 has two states. In the initial state, the filter assembly 20 is not located in the upper partition cavity 10a1. When the dust container lid 122 is placed on the housing body 121 to close the opening of the upper partition cavity 10a1, interference between the pivoting element 131 and the dust container lid 122 prevents proper closure. Interference between the pivoting element 131 and the dust container lid 122 means a spatial overlap or displacement of the structures.This means that the pivoting element 131 projects outwards in the opposite direction to the mounting direction of the dust container lid 122 onto the housing body 121 and bears against the dust container lid 122, so that this dust container lid 122 cannot close flush with the opening of the upper partition cavity 10a1. The other is the operating state of the pivoting element 131. In the operating state, the filter assembly 20 is located in the upper partition cavity 10a1. In this state, the filter assembly 20 initially interferes with the pivoting element 131 and rests against it, causing the pivoting element 131 to rotate about its axis. The rotation of the pivoting element 131 about its axis eliminates the interference between the pivoting element 131 and the dust container lid 122, allowing the dust container lid 122 to be closed with the housing body 121.This means that the pivoting element 131 of the filter incorrect mounting protection device 13 is switched between the initial state and the operating state by relative rotation to the inner wall of the upper separating cavity 10a1. Here, the closed state of the dust container lid 122 with the housing body 121 means that the dust container lid 122 tightly seals the opening end of the upper separating cavity 10a1 of the housing body 121 without distortion or fitting problems. This prevents the dust container lid 122 from being closed with the housing body 121 when installing the filter assembly 20, as long as the filter assembly 20 is not inserted into the housing body 121. This serves as a reminder to the user to insert the filter assembly 20 into the housing body 121. The dust container lid 122 can only be closed with the housing body 121 once the filter assembly 20 is inserted into the dust container cavity 10a. This design prevents both failure to install and incorrect installation of the filter assembly 20, thereby improving the user experience. With reference to Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 to 16, the pivoting element 131 in some embodiments comprises a first interference section 1311, which interferes with the dust container lid 122, and a second interference section 1312, which interferes with the filter assembly 20, wherein the first interference section 1311 is connected to the second interference section 1312. If the filter assembly 20 is not inserted into the upper separation cavity 10a1, the first interference section 1311 rests against the dust container cover 122, so that the dust container cover 122 cannot be closed with the housing body 121. When the filter assembly 20 is inserted into the upper separation cavity 10a1, the second interference section 1312 rests against the filter assembly 20 and causes the pivoting element 131 to pivot, thereby releasing the contact position between the first interference section 1311 and the dust container cover 122, so that the dust container cover 122 is closed with the housing body 121. It is understood that the first interference section 1311 and the second interference section 1312 are two sections of the pivoting element 131, each interfering with and in contact with the dust container cover 122 and the filter assembly 20, respectively. The two interference sections rotate synchronously around the axis to allow the pivoting element 131 to switch between its initial state and its operating state. The pivoting element 131 is in its initial state when the filter assembly 20 is not inserted into the upper separation cavity 10a1 and the first interference section 1311 is in contact with the dust container lid 122. When the filter assembly 20 is inserted into the upper separation cavity 10a1, it interferes with and contacts the second interference section 1312, causing the entire pivoting element 131 to rotate about its axis. This causes the first interference section 1311 to rotate about its axis together with the second interference section 1312 and separate from the dust container lid 122, thus eliminating the interfering positional relationship. In this way, the first interference section 1311 and the second interference section 1312 of the pivoting element 131 alternately interfere with the dust container lid 122 and the filter assembly 20, respectively. This ensures that, even when the filter assembly 20 is not installed, the interference between the first interference section 1311 and the dust container lid 122 remains in the upper separating cavity 10a1, preventing it from being closed by the housing body 121. With reference to Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 to 16, in some embodiments the first interference section 1311 has a first interference surface 131a for contact with the dust container lid 122, wherein the first interference surface 131a is planar; and / or the second interference section 1312 has a second interference surface 131b for contact with the filter assembly 20, wherein the second interference surface 131b is arcuate. It is understood that the flat first interference surface 131a offers a larger contact area with the dust container lid 122, so that the contact of the first interference section 1311 with the dust container lid 122 is more stable. This means that as long as the filter assembly 20 is not inserted into the upper separation cavity 10a1, the interference between the first interference section 1311 and the dust container lid 122 remains stable for a longer period. In contrast, the arc-shaped second interference surface 131b has a smaller contact area with the filter assembly 20. When the filter assembly 20 is inserted into the upper separation cavity 10a1, it generates a thrust by contacting the second interference section 1312, which causes the entire pivoting element 131 to rotate. This eliminates the interference effect between the first interference section 1311 and the dust container lid 122, allowing the dust container lid 122 to be easily closed with the housing body 121. When the dust container lid 122 rests against the first interference surface 131a, the pivoting element 131 is in a stable state, meaning that no total rotation of the pivoting element 131 about the axis is triggered. However, when the filter assembly 20 rests against the second interference surface 131b, the pivoting element 131 is in a dynamic state, meaning that a total rotation of the pivoting element 131 about the axis is triggered. With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 to Fig. 16, in some embodiments a plug-in section 122a is provided on the dust container lid 122 for contact with the first interference surface 131a, wherein the plug-in section 122a protrudes from the inner surface of the dust container lid 122. It is understood that the plug-in section 122a is a projecting structure extending from the surface of the dust container lid 122. The design of the plug-in section 122a includes, but is not limited to, plug-in blocks, plug-in pins, and plug-in ribs. That is to say, the arrangement of the plug-in section 122a reduces the contact distance between the surface of the dust container lid 122 and the first interference surface 131a, so that interference between the two parts is achieved without adjusting the dimensions of the first interference section 1311. In this way, the sensitivity of the interference can be further improved by the interference between the plug section 122a formed above and the first interference surface 131a, i.e., the spatial degree of interference between the dust container lid 122 and the first interference section 1311 is increased. With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 to Fig. 16, in some embodiments a support section 10a4 is provided in the upper separating cavity 10a1, and a pivot pin 132 is arranged on the pivoting element 131 for rotatable connection with the support section 10a4. It is understood that the support section 10a4 is a fixed structural part connected to the inner wall of the upper partition cavity 10a1, while the pivot pin 132 is a structural part that is rotatable about an axis relative to the support section 10a4. For example, the support section 10a4 is designed as two U-shaped structural parts, which are formed in the upper separating cavity 10a1 and spaced apart from each other. A pivot pin 132 is arranged on the pivot element 131 in the direction of the axis of rotation, with each pivot pin 132 being supported on the associated U-shaped structural part. Of course, in other examples, the support section 10a4 can also be designed as a Y-shaped or O-shaped structural part. In this way, the rotating part of the swivel element 131 is rotatably connected to the support section 10a4, so that the swivel element 131 can pivot about an axis relative to the housing body 121. With reference to Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 to 16, the filter misassembly protection device 13, in some embodiments, further comprises a return element 133, which is mounted on the pivot pin 132. When the filter assembly 20 is removed from the upper separating cavity 10a1, the return element 133 returns the first interference section 1311 to the position in which it is in interference with the dust container cover 122. It is understood that the pivoting element 131 initially remains in its initial state during use and only subsequently switches to its operating state under the action of the filter assembly 20. Therefore, when the filter assembly 20 is removed from the upper separation cavity 10a1, the first interference section 1311 of the pivoting element 131 must be returned to its initial state. The design of the return element 133 includes, but is not limited to, torsion springs, spring plates and coil springs. In this way, the restoring element 133 increases the restoring speed of the pivoting element 131, especially for the next operating cycle of the filter assembly 20, so that the first interference section 1311 is again in interfering system with the dust container cover 122. With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 to Fig. 16, in some embodiments a limiting structure 122b is provided on the dust container lid 122 to limit the upward and downward movement of the filter assembly 20 in the installation direction, wherein the limiting structure 122b abuts the filter assembly 20. It is understood that after closing the dust container lid 122 with the housing body 121, a certain mounting gap must exist between the dust container lid 122 and the filter assembly 20 to ensure mounting adjustment between the dust container lid 122 and the filter assembly 20 and to facilitate the placement of the dust container lid 122 onto the opening of the upper partition cavity 10a1. At the same time, however, the filter assembly 20 must be confined within the upper partition cavity 10a1, particularly within its range of motion in the installation direction. For this reason, the confining structure 122b is provided on the dust container lid 122. The design of the boundary structure 122b includes, but is not limited to, boundary projections, boundary ribs and boundary blocks. In this way, the limiting structure 122b exerts a supporting effect on the filter assembly 20 when the dust container cover 122 is closed to the housing body 121, and the range of movement of the filter assembly 20 in the installation direction is limited. With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 to Fig. 16, in some embodiments a reverse mounting protection limiting section 10k is provided in the upper separating cavity 10a1, and a limiting counterpart 20a matching the reverse mounting protection limiting section 10k is arranged on the filter assembly 20 to ensure a correct installation direction of the filter assembly 20 in the upper separating cavity 10a1. Specifically, the reverse mounting protection limiting section 10k comprises ribs on the inner wall of the upper separating cavity 10a1; the limiting counterpart 20a comprises mounting grooves in the filter assembly 20 into which the ribs engage. It is understood that by fitting the ribs into the mounting grooves, the installation direction of the filter assembly 20 in the upper separation cavity 10a1 is checked. For example, a rib can be provided on each of two diagonally opposite inner walls of the upper partition cavity 10a1, and a corresponding mounting groove can be provided on each diagonally opposite side walls of the filter assembly 20. The filter assembly 20 will only be inserted into the upper partition cavity 10a1 in the correct orientation if both ribs engage in the corresponding mounting grooves. The reverse mounting protection limiting section 10k can also be designed as a projection or block, and the limiting counterpart 20a can also be designed as a through hole or blind hole in the filter assembly 20. With reference to Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 to 16, the upper housing 12, in some embodiments, further comprises a key assembly 30, which is movably connected to the housing body 121. A first mounting groove 10h and a second mounting groove 10i are formed in the housing body 121, located on opposite sides of the dust container cover 122. The key assembly 30 is movably arranged in the first mounting groove 10h, with the direction of movement of the key assembly 30 being parallel to the direction of the distance between the first mounting groove 10h and the second mounting groove 10i. It is understood that during operation, the user places one finger in the second mounting groove 10i and uses another finger to actuate the button assembly 30 in the first mounting groove 10h, causing this button assembly 30 to slide in the first mounting groove 10h. The movable connection of the button assembly 30 in the first mounting groove 10h can be achieved by relative sliding between a guide rail and a slider, or the button assembly 30 can be arranged to slide directly in the first mounting groove 10h. In this way, a force directed in the direction of the distance between the first mounting groove 10h and the second mounting groove 10i is exerted on the key assembly 30 in order to actuate the key assembly 30, thereby making it easy to remove the housing 10 from the main unit of the cleaning device, especially if there is no point of attack on the main unit. With reference to Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 to 16, the key assembly 30 comprises, in some embodiments, a key body 31 and an elastic element 32. A locking arm 33 is arranged on opposite sides of the key body 31. A locking groove 10j for receiving the locking arm 33 is formed on the wall of the first mounting groove 10h. One end of the elastic element 32 is connected to the lower end of the key body 31, and the other end is connected to the wall of the first mounting groove 10h. At the upper end of the key body 31, a limiting projection 34 is provided, which is opposite the elastic element 32. It is understood that the elastic element 32 is constantly compressed, so that the key body 31 is constantly held in place. Simultaneously, the locking arm 33 slides in the locking groove 10j, so that the key body 31 moves exclusively in the first mounting groove 10h. During the movement of the key body 31 in the first mounting groove 10h, the limiting projection 34 engages with or disengages from the inner wall of the main unit of the cleaning device, thereby achieving a limitation or release of the housing 10 relative to the main unit. With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 to Fig. 16, in some embodiments a dust outlet opening 10g is formed on a side wall surface 10d of the lower housing 11, which is opposite the air inlet 10e. The housing 10 includes a dust container opening cover 60 for closing the dust outlet opening 10g; or the housing 10 includes a dust collection hinged assembly 70 at the dust outlet opening 10g. It is understood that the dust outlet 10g is the outlet through which dust and particles are discharged from the dust container cavity 10a. Depending on practical requirements, the user can attach either the dust container opening cover 60 or the dust collection flap assembly 70 to the dust outlet 10g. The dust container opening cover 60 is used for a non-self-vacuuming integrated dust container / water tank assembly 100, which requires manual cleaning of the dust container cavity 10a. In contrast, attaching the dust collection flap assembly 70 to the dust outlet 10g allows connection to a dust collection container or cleaning station, thus fulfilling the requirement for automatic cleaning of the dust container cavity 10a. Referring to Figures 17, 18 to 19, in some embodiments the water tank cavity 10b is arranged opposite the air intake opening 10f. A water outlet connection assembly 40 is provided on the lower inner wall of the water tank cavity 10b. It is understood that the integrated dust container / water tank assembly 100 must be detachable from the main unit of the cleaning device, so that the water path in the water tank cavity 10b must also be detachably connected to the main unit. The water outlet connection assembly 40 serves to create a pluggable connection between the water path in the water tank cavity 10b and the main unit. In this way, the water outlet connection assembly 40 is connected to the main unit of the cleaning device. When the integrated dust container / water tank assembly 100 is removed from the main unit, the water outlet hole on the integrated dust container / water tank assembly 100 is closed. This facilitates disassembly from the main unit and simplifies cleaning. Specifically, the water outlet connection assembly 40 comprises a valve body 41 arranged on the inner wall of the water tank cavity 10b, a valve cover 42 telescopically connected to the valve body 41, and a sealing element 43 with an opening 43a. A water outlet hole 10n is formed on the lower inner wall of the water tank cavity 10b. The sealing element 43 is arranged at the water outlet hole 10n. The valve cover 42 rests against the sealing element 43 and closes the opening 43a. When pressurized, the valve cover 42 moves away from the sealing element 43, thus opening the opening 43a. A filter unit 50 is also provided on the lower inner wall of the water tank cavity 10b, one end of which is connected to the valve body 41 and the other end of which is connected to the water tank cavity 10b. It is understood that, for water to be drawn from the water tank cavity 10b by the main unit of the cleaning device, a connecting piece on the main unit is inserted into the opening 43a of the sealing element 43. The sealing element 43 serves to increase the watertight seal between the water tank cavity 10b and the connecting piece. At the same time, the connecting piece pushes the valve cover 42 away, so that this valve cover 42 moves away from the sealing element 43. This puts the water outlet connection assembly 40 in the open position. Clear water in the water tank cavity 10b passes through the filter unit 50 into the valve body 41 and flows to the main unit of the cleaning device. When the connecting piece of the main unit is withdrawn from the opening 43a of the sealing element 43, the valve cover 42 returns to its initial position, rests against the sealing element 43, and closes the opening 43a of the sealing element 43.This prevents clear water from escaping from the water tank cavity 10b through the water outlet connection assembly 40, thus enabling a detachable connection of the water tank cavity 10b to the main unit. The valve body 41 preferably has a box-shaped structure with a closed end and an open end, its open end resting against the sealing element 43. The valve cover 42 is telescopically connected to the valve body 41 via elastic structures such as springs or spring plates, as well as telescopic structures. The filter unit 50 has a water inlet that connects to the water tank cavity 10b, and a water outlet that connects to the valve body 41. The filter unit 50 is connected to the valve body 41 via a pipe. With reference to Figures 17, 18 to 19, in some embodiments the valve body 41 comprises a first outer housing 411 and a guide tube column 412 arranged in the first outer housing 411. A water inlet end 41a for connection to the filter unit 50 is provided on the first outer housing 411. The valve cover 42 comprises a closure section 421 and a connecting section 422 connected to the closure section 421. An elastic element 44 is placed on the guide tube column 412 and bears against the closure section 421, so that this closure section 421 rests against the sealing element 43. The connecting section 422 is inserted into the guide tube column 412. It is understood that the guide tube column 412 serves to appropriately limit and guide the elastic element 44 and is hollow inside. The closure section 421 rests against the sealing element 43 under the pressure of the elastic element 44. The elastic element 44 also surrounds the connecting section 422. When the closure section 421 moves telescopically together with the elastic element 44, the connecting section 422 engages in or extends from the guide tube column 412, thereby fulfilling a secondary positioning and guiding function. In this way, the elastic element 44 is placed on the guide tube column 412 and is supported against the closure section 421, so that this closure section 421 rests against the opening 43a of the sealing element 43. This prevents water from escaping after the integrated dust container-water tank assembly 100 is detached from the main unit. When the elastic element 44 is compressed, the closure section 421 releases the opening 43a of the sealing element 43 and moves towards the guide tube column 412. At the same time, the connecting section 422 engages further in the guide tube column 412, thus enabling continuous compression of the elastic element 44. With reference to Figures 17, 18 to 19, in some embodiments the filter unit 50 comprises a second outer housing 51, a separate cover plate 52, and a filter element 53. The second outer housing 51 is recessed inwards from the lower inner wall of the tank. The cover plate 52 closes the open end of the second outer housing 51, thus forming a closed space. The filter element 53 is arranged in this closed space. The second outer housing 51 has a water outlet opening 51a for connection to the valve body 41 and a water inlet. It is understood that the second outer casing 51 is formed in one piece on the lower inner wall of the water tank cavity 10b, while the cover plate 52 lies outside the water tank cavity 10b and closes the second outer casing 51 to form the enclosed space. The cover plate 52 can be connected to the second outer casing 51 by means of screws. To replace the filter element 53, the screws are loosened and the cover plate 52 is removed. The water path leads from the water inlet into the enclosed space, is filtered through the filter insert 53 and then flows out through the water outlet opening 51a. In this way, the filter insert 53 can be exposed by removing the cover plate 52 to allow for later replacement. With reference to Fig. 17, Fig. 18 to Fig. 19, in some embodiments the filter unit 50 comprises a conduit 54 which is connected at one end to the water outlet opening 51a and at the other end to the valve body 41. It is understood that the stored water in the water tank cavity 10b, after entering the closed space formed by the second outer housing 51 and the cover plate 52, is filtered by the filter insert 53 and then directed through the conduit 54 to the water outlet connection assembly 40. With reference to Fig. 17, Fig. 18 to Fig. 19, in some embodiments the filter unit 50 further comprises a sealing ring 55 which is arranged on the cover plate 52 and surrounds the filter insert 53. Here, the sealing ring 55 increases the tightness between the cover plate 52 and the second outer housing 51 in order to reduce fluid leakage between these parts. With reference to Fig. 20 and Fig. 21, a second aspect of the embodiments of the present application further provides a cleaning device comprising a main unit 200 and the integrated dust container-water tank assembly 100 described above. With the aforementioned integrated dust container-water tank assembly 100, the cleaning device has a higher suction power and can be miniaturized more easily. With reference to Figures 20 and 21, the cleaning device in some embodiments comprises a central brush assembly 201, a suction assembly 202, and a pump body 203. The central brush assembly 201 is arranged adjacent to the integrated dust container / water tank assembly 100 and is connected to the dust container cavity 10a via the air inlet 10e. The suction assembly 202 is arranged adjacent to the integrated dust container / water tank assembly 100 and is connected to the dust container cavity 10a via the air intake opening 10f. The pump body 203 is arranged opposite the suction assembly 202. The water outlet connection assembly 40 is provided on the integrated dust container / water tank assembly 100, and the pump body 203 is connected to the integrated dust container / water tank assembly 100 via this water outlet connection assembly 40. It is understood that the suction port of the suction assembly 202 can direct the airflow from the dust container cavity 10a of the integrated dust container / water tank assembly 100 directly through the air intake opening 10f, without the need for an additional connecting duct. This further reduces costs and minimizes flow losses. Furthermore, corresponding components are arranged around the integrated dust container / water tank assembly 100, resulting in a more compact rear section of the main unit 200. By simultaneously implementing several functions, space is used optimally and costs are reduced. The above are merely preferred embodiments of the present application and are not intended to limit it. Any modifications, equivalent replacements, and improvements within the scope of the present application are to be included within its scope of protection.
