When FIG. 6 and FIG. 8 through FIG. 11 are combined, the tank cover assembly (3) further includes a waste barrier plate (7), the waste barrier plate (7) is connected to a separation means (6), and the waste barrier plate (7) is installed in a first chamber, that is, the waste barrier plate (7) is connected to the upper part of the separation means (6), a second leakage part (71) is installed on the waste barrier plate (7), and a first leakage part (61) is installed on one side of the waste barrier plate (7). When the tank cover assembly (3) is separated from the tank body (2), the installation of the waste barrier plate (7) causes the waste inside the sewage tank to gather in the area surrounded by the separation means (6) and the waste barrier plate (7), thereby preventing the waste from falling directly onto the floor, preventing secondary pollution, and facilitating waste sorting.
[0080] Combining FIGS. 6 and FIGS. 8 through 11, in some embodiments, the waste barrier plate (7) may be connected only to at least a portion of the area around the separation means (6). For example, preferably, the waste barrier plate (7) is connected to one side away from the main device (1) of the separation means (6), that is, the waste barrier plate (7) is installed at the rear side of the separation means (6). In actual practice, when the user separates the tank cover assembly (3) from the tank body (2), the wastewater tank is inclined toward the user, that is, the wastewater tank is inclined toward the rear side, and under the condition that the waste barrier plate (7) is connected to the rear side of the separation means (6), when the tank cover assembly (3) is separated, if wastewater is present in the first chamber, the wastewater flows to the rear area of the waste barrier plate (7) through the second leakage portion (71) on the waste barrier plate (7), and the waste is stored in the front area of the separation means (6) and the waste barrier plate (7), making it convenient for the user to clean up the waste.
[0081] When combining FIGS. 6 and FIGS. 8 to 11, in some embodiments, the second leakage portion (71) includes a second leakage hole installed in a grid shape on the waste barrier plate (7), thereby preventing wastewater from remaining on the boundary side between the waste barrier plate (7) and the separation means (6), and thus preventing the phenomenon of wastewater leaking outside the wastewater tank and causing secondary contamination after the tank cover assembly (3) is separated.
[0082] Combining FIGS. 6 and FIGS. 8 through 11, in some embodiments, a first leakage portion (61) is installed on the front side of the waste barrier plate (7) and is configured to securely separate the first chamber and the second chamber formed by the separation means (6). An avoidance portion (72) is installed on one side (i.e., the rear side) of the waste barrier plate (7) away from the main device (1), and the avoidance portion (72) extends in a direction toward the interior of the main device (1) (i.e., the front side) to form a guide groove, and a third leakage portion (64) is installed on the separation means (6), at least a portion of the third leakage portion (64) is installed within the projection of the avoidance portion (72), and the third leakage portion (64) may be a third leakage hole, which is installed immediately below the avoidance portion (72). When using the cleaning device, wastewater exists between the waste barrier plate (7) and the wastewater tank, and the installation of the avoidance portion (72) and the third leakage portion (64) is configured to allow wastewater to flow into the wastewater tank, thereby acting as an induction agent. When the tank cover assembly (3) is separated, wastewater located at the rear side of the waste barrier plate (7) flows into the wastewater tank through the avoidance portion (72) and the third leakage portion (64). In another embodiment, the waste barrier plate (7) may have a gap between it and the rear wall of the tank body (2) of the wastewater tank, and a first leakage portion (61) is installed on both the front and rear sides of the waste barrier plate (7), and when the tank cover assembly (3) is separated, the flow of wastewater located at the rear side of the waste barrier plate (7) flows into the wastewater tank through the gap and the third leakage portion (64).
[0083] In another embodiment, the waste barrier plate (7) may be surrounded on the upper part of the separation means (6), and when the tank cover assembly (3) is separated, the waste remains on the separation means (6) between the waste barrier plates (7). However, this assembly method is an optional method because, when cleaning the waste, the tank cover assembly (3) must be flipped over or a manual cleaning method must be adopted, making waste cleaning more difficult compared to the method of connecting the waste barrier plate (7) to a part of the separation means (6).
[0084] Combining FIGS. 6 and FIGS. 8, in some embodiments, the tank cover assembly (3) further comprises a guide means (8), said guide means (8) is installed above the mounting hole (62) of the separation means (6). Under conditions where the tank cover assembly (3) is assembled in the wastewater tank, the guide means (8) is installed spaced above the absorption pipe (23). Under conditions where the wastewater tank is used, the wastewater in the wastewater tank is ejected through the upper part of the absorption pipe (23), passes through the guide means (8), is blocked, and then collects in the first chamber.
[0085] When combining FIGS. 6 and FIGS. 8, specifically when implemented, the guide means (8) may have a U-shaped structure, the opening of the U-shaped structure of the guide means (8) faces downward, and the side walls on both sides of the guide means (8) are connected to the separation means (6) through the support (9).
[0086] In some embodiments, a sealing separator plate (81) may be installed on the rear side of the guide means (8) so that the guide groove is formed into a cover-type structure with the bottom and front sides open.
[0087] When combining FIGS. 6 to 8, in some embodiments, the cover (31) may be integrally molded on the upper part of the guide means (8), and an air intake (34) is installed on the side wall of the cover (31), and the air intake (34) is installed above the guide means (8), and the air intake (34) serves as the entrance of the air intake passage and can draw out air from the wastewater tank.
[0088] Based on the above-described wastewater tank, the present invention further provides a cleaning device, wherein the cleaning device comprises a main device (1) and the wastewater tank, wherein the main device (1) is provided with a receiving cavity (11), and the receiving cavity (11) is provided with an assembly opening communicating with the outside of the main device (1); the wastewater tank comprises a tank body (2), and at least a portion of the tank body (2) is detachably assembled within the receiving cavity (11) through the assembly opening.
[0089] In related technologies, separating and attaching the wastewater tank from the main device is cumbersome and affects the user experience. Based on this, the present invention provides a cleaning device and can improve the user experience by simplifying the process of separating the wastewater tank from the main device at least to some extent.
[0090] Combining FIGS. 1 and FIGS. 2, the present invention provides a cleaning device, wherein a wastewater tank is detachably assembled on a main device (1), and a pushable button (12) is installed on the main device (1), and by pressing the button (12) to release the connection between the wastewater tank and the main device (1), the wastewater tank can be quickly separated from the main device (1). For example, by holding the wastewater tank with one's hand and separating the wastewater tank from the main device (1), the wastewater inside the tank is separated during the separation process, thereby preventing to some extent the risk of secondary contamination caused by the wastewater spilling onto the floor, thus providing excellent practicality.
[0091] According to the cleaning device provided in the present invention, a pushable button (12) is installed on the main device (1), and by pressing the button (12) to disconnect the sewage tank from the main device (1), the sewage tank is quickly separated from the main device (1), thereby simplifying the process of separating the sewage tank from the main device, improving the user experience, and providing excellent practicality.

A gap exists between the structural means (14) and the housing (13). A connecting means (15) is installed on the circumference of the button (12), and the connecting means (15) is inserted and coupled into the gap between the structural means (14) and the housing (13), thereby realizing that the button (12) is assembled on the main device (1).
[0094] When combining FIGS. 12 to 14, in some embodiments, a positioning groove (16) is installed on a connecting means (15), and the opening of the positioning groove (16) faces the outside of the main device (1). A positioning means (17) is connected to the inner wall of the housing (13), and the positioning means (17) is installed in the positioning groove (16) of the connecting means (15), thereby increasing the reliability of assembling the connecting means (15) onto the main device (1) and, correspondingly, improving the reliability of assembling the button (12) onto the main device (1).
[0095] When combining FIGS. 12 to 14, in some embodiments, the connecting means (15) comprises a first plate body (151), a second plate body (152), and a third plate body (153), and the first plate body (151), the second plate body (152), and the third plate body (153) are sequentially connected to the circumferential surface of the button (12) in a direction away from the button (12), and an angle is formed between the second plate body (152) and the first plate body (151), and it is preferable that the angle be obtuse, and the second plate body (152), the first plate body (151), and the circumferential surface of the button form the positioning groove (16), and the third plate body (153) is inserted and coupled within the gap between the structural means (14) and the housing (13).
[0096] When combining FIGS. 12 to 14, specifically when implemented, the first plate body (151) is perpendicular to the circumferential surface of the button (12), and the second plate body (152) is installed at an angle with respect to the depth direction of the button (12). Additionally, the outer end of the second plate body (152) is installed in a direction away from the button (12), thereby increasing the opening size of the positioning groove (16), making it convenient for the positioning means (17) to be assembled within the positioning groove (16). Furthermore, since the third plate body (153) is perpendicular to the circumferential surface of the button (12), the connecting means (15) forms a 'Z'-shaped structure. Additionally, the positioning means (17) may have a plate-like structure and may be integrally molded on the inner wall of the housing (13).
[0097] It should be explained that the above-mentioned connecting means (15) may be installed in multiple numbers spaced apart and surrounding the circumference of the button (12), and of course, only one connecting means (15) may be installed and is installed surrounding the circumference of the button (12). Correspondingly, the positioning means (17) may be installed in multiple numbers or as one corresponding to the connecting means (15), and is not limited thereto.
[0098] The middle portion of the button (12) of the embodiment of the present invention may have elasticity, and when the button (12) is pressed, the inner portion of the button (12) comes out into the main device (1).
[0099] Combining FIGS. 12 to 14, in some embodiments, a guide surface (121) is installed at one end of the button (12) facing the interior of the main device (1), and the guide surface (121) is inclined with respect to the depth direction of the button (12).
