By distributing the sewage tank 20 on the rear side of the floor scrubber body 30. When the floor scrubber 100 is in use, the sewage tank 20 is closer to the ground. Therefore, the floor brush assembly 10, the handle assembly 40 and the sewage tank 20 can be disassembled for use, which is convenient for installation and disassembly, thereby improving the user experience.

[0074] See also Figure 2 , Figure 3 as well as Figure 4 , Figure 2 It is a structural schematic diagram of an embodiment of a sewage tank of the present application; Figure 3 is a cross-sectional schematic diagram of an embodiment of a sewage tank of the present application; Figure 4 It is a partial cross-sectional schematic diagram of an embodiment of a sewage tank of the present application in a first movement position. The sewage tank 20 includes a sewage tank shell 21 and a sewage liner assembly 22. The sewage tank shell 21 is provided with a sewage cavity 211 having a sewage installation port 2111. The sewage installation port 2111 provides an installation position for the sewage liner assembly 22. The sewage liner assembly 22 is sealedly connected to the sewage installation port 2111. Among them, the sewage liner assembly 22 can be sealedly connected to the sewage installation port 2111 through a sewage liner sealing ring 224, meeting the sealing requirements of the sewage tank 20, so that the sewage tank 20 can be used at any angle such as lying flat or standing upright.

[0075] The sewage tank 20 also includes a filter basket assembly 27. The filter basket assembly 27 is located in the sewage cavity 211. The filter basket assembly 27 is used to filter the inhaled matter in the sewage inlet pipe 212, so that larger particles are piled in the filter basket assembly 27, thereby achieving dry and wet separation, etc. The filter basket assembly 27 includes a filter mounting portion 271 and a filter portion 272. The filter mounting portion 271 is connected to the filter portion 272. Among them, the filter mounting portion 271 and the filter portion 272 are detachably or fixedly connected. As in the present embodiment, the filter mounting portion 271 and the filter portion 272 are welded or integrally formed. The filter mounting portion 271 is used for installation; and the filter portion 272 is used to filter and accumulate larger particles, etc. Larger particles can be, but are not limited to, solid substances and insoluble substances.

[0076] See also Figure 5 , Figure 6 as well as Figure 7 , Figure 5 It is a partial structural schematic diagram of an embodiment of a sewage tank of the present application in a second movement position; Figure 6 yes Figure 4 A schematic diagram of the structure shown; Figure 7 It is a schematic diagram of a first partial cross section of an embodiment of the sewage tank of the present application in the second movement position. The filter mounting part 271 can be releasably locked and can be rotated on the side end of the sewage lining component 22. Among them, the filter mounting part 271 can be releasably locked on the side end of the sewage lining component 22. For example, the filter mounting part 271 is locked on the side end of the sewage lining component 22; or, the filter mounting part 271 is disconnected from the side end of the sewage lining component 22. In addition, the filter mounting part 271 can be rotated on the side end of the sewage lining component 22. When the filter mounting part 271 is disconnected from the side end of the sewage lining component 22, the filter mounting part 271 can rotate a certain angle relative to the side end of the sewage lining component 22, wherein the filter part 272 rotates a certain angle with the filter mounting part 271. The filter part 272 is provided with a filter hole 2721. The filter hole 2721 is used for filtering. The number and shape of the filter hole 2721 can be determined according to actual needs and are not limited here. The above-mentioned locking method can be, but is not limited to, snap-in and plug-in. The rotation method may include but is not limited to pivoting, rotating, and hinged.

[0077] The filter basket assembly 27 has at least a first movement position and a second movement position. When the filter basket assembly 27 is in the first movement position, the filter mounting portion 271 can be locked to the side end of the sewage liner assembly 22, and the filter portion 272 is located in the sewage cavity 211. The first movement position can be an initial position, that is, the filter basket assembly 27 is located in the sewage cavity 211 as a whole and cannot move. The filter portion 272 is used for dry and wet separation of inhaled matter, and separates larger inhaled particles, so that the larger particles of inhaled matter are stacked on the filter portion 272.

[0078] When the filter basket assembly 27 is in the second movement position, the filter mounting portion 271 is unlocked from the sewage lining assembly 22, and then the filter mounting portion 271 rotates relative to the sewage lining assembly 22. When it is necessary to clean the suction in the sewage tank 20, the sewage lining assembly 22 is taken out of the sewage tank housing 21, and the filter basket assembly 27 is rotated to the second movement position, which can increase the opening of the filter basket assembly 27 and tilt downward, so as to facilitate cleaning of the suction accumulated on the filter portion 272, thereby improving the user experience.

[0079] Through the interaction of the sewage tank housing 21, the sewage liner assembly 22 and the filter basket assembly 27, the filter basket assembly 27 has at least a first movement position and a second movement position. When the filter basket assembly 27 is in the first movement position, the filter portion 272 is used to separate the dry and wet inhaled matter, and to separate larger inhaled particles so that the larger particles of inhaled matter are piled on the filter portion 272. When the filter basket assembly 27 is in the second movement position, the second movement position can increase the opening of the filter basket assembly 27 and tilt downward, which is convenient for cleaning the inhaled matter accumulated on the filter portion 272, thereby improving the user experience.

[0080] In some embodiments, the sewage tank 20 includes a sewage tank cover 25 and a sewage button assembly 28. The sewage tank cover 25 is connected to the sewage lining assembly 22. The sewage tank cover 20 and the sewage lining assembly 22 are detachably or fixedly connected. The sewage tank cover 20 can move with the sewage lining assembly 22. When the sewage lining assembly 22 is removed or installed relative to the sewage tank housing 21, the sewage tank cover 20 is also removed or installed with the sewage lining assembly 22.

[0081] The upper part of the sewage button assembly 28 is clamped to the upper part of the floor scrubber body 30. The lower part of the sewage button assembly 28 is releasably abutted against the filter mounting portion 271. The sewage button assembly 28 of the sewage tank 20 is releasably clamped to the floor scrubber body 30. The sewage button assembly 28 is not only used to release the clamping connection between the sewage tank 20 and the floor scrubber body 30, but also can be used to release the locking connection between the filter basket assembly 27 and the sewage liner assembly 22, that is, to achieve the reusability of the sewage button assembly 28.

[0082] The above-mentioned sewage button assembly 28 is provided with a button handle 2815. The upper cover of the sewage tank 20 is provided with a button handle groove 255. The button handle groove 255 corresponds to the button handle 2815. The user disconnects the sewage tank 20 and the floor scrubber body 30 through the button handle 2815. Then, the user continues to act on the button portion 2812 or the button handle 2815 of the button member 281, so that the filter basket assembly 27 is in the second movement position, which is convenient for cleaning the suction objects, etc.

[0083] In some embodiments, when the filter mounting portion 271 is unlocked from the side end of the sewage liner assembly 22, the filter mounting portion 271 moves downward in a first direction and can rotate relative to the side end of the sewage liner assembly 22. The first direction may be, but is not limited to, a vertical direction. After the filter mounting portion 271 moves vertically downward for a certain distance, the filter mounting portion 271 rotates relative to the side end of the sewage liner assembly 22, which can increase the rotation range of the filter basket assembly 27, thereby making it easier to clean the inhaled matter accumulated on the filter portion 272, thereby further improving the user experience.

[0084] The filter mounting portion 271 and the side end of the sewage lining assembly 22 are releasably locked and connected, wherein the locking method may be, but is not limited to, snap-fitting and plug-in. In a specific embodiment, the filter mounting portion 271 and the side end of the sewage lining assembly 22 are releasably snap-fitted. For example, the filter mounting portion 271 is provided with a filter snap-fitting portion 2711. Among them, the filter snap-fitting portion 2711 can be detached or fixed to the filter mounting portion 271. As in this embodiment, the filter snap-fitting portion 2711 is welded or integrally formed with the filter mounting portion 271. The side end of the sewage lining assembly 22 is provided with a liner snap-fitting groove 2231. When the filter basket assembly 27 is in the first movement position, the filter snap-fitting portion 2711 is snap-fitted to the liner snap-fitting groove 2231. When the filter basket assembly 27 is in the second movement position, the filter snap-fitting portion 2711 is snap-fitted with the liner snap-fitting groove 2231.

[0085] Through the cooperation between the filter clamping portion 2711 and the liner clamping groove 2231, not only a releasable locking connection between the filter mounting portion 271 and the side end of the sewage liner assembly 22 is achieved, but also the structure is simple and easy to operate and implement.

[0086] The clamping relationship between the filter clamping portion 2711 and the inner liner clamping groove 2231 can be released in a variety of ways, for example, manually or automatically. The manual and automatic release of the clamping relationship will be described in detail below.

[0087] In one embodiment, a filter basket buckle hand is provided on the side of the filter clamping part 2711 away from the liner clamping groove 2231 (not shown in the figure). The filter basket buckle hand is welded or integrally formed on the side of the filter clamping part 2711 away from the liner clamping groove 2231. The filter basket buckle hand facilitates the user to manually release the clamping connection between the filter clamping part 2711 and the liner clamping groove 2231, thereby releasing the clamping connection between the filter basket assembly 27 and the sewage liner assembly 22, thereby facilitating the subsequent rotation of the filter basket assembly 27 relative to the sewage liner assembly 22. The number and shape of the filter basket buckle hand are not limited, and can be convenient for the user's manual operation.

Figures 1 to 7 In some embodiments, the sewage liner assembly 22 includes a sewage liner 223. The sewage button assembly 28 is disposed between the sewage tank cover 25 and the sewage liner 223. The sewage button assembly 28 is detachably disposed between the sewage tank cover 25 and the sewage liner 223. The sewage button assembly 28 is releasably abutted against the filter clamping portion 2711. The sewage button assembly 28 is released from abutment with the filter clamping portion 2711, and there is no abutment relationship between the two. At this time, the filter basket assembly 27 is in the first movement position. The sewage button assembly 28 is abutted against the filter clamping portion 2711, and the filter clamping portion 2711 is released from the liner clamping groove 2231, and then the filter basket assembly 27 is rotated relative to the side end of the sewage liner assembly 22, so that the filter basket assembly 27 is in the second movement position.

[0089] The sewage button assembly 28 facilitates the user to automatically release the clamping connection between the filter clamping portion 2711 and the liner clamping groove 2231, thereby automatically releasing the clamping connection between the filter basket assembly 27 and the sewage liner assembly 22, thereby facilitating the rotation of the filter basket assembly 27 relative to the sewage liner assembly 22. The sewage button assembly 28 can be, but is not limited to, squeeze-driven and push-driven.

When the vertical limit between the second stroke groove 2234 and the second stroke shaft 2713 between the filter mounting part 271 and the sewage liner assembly 22 is released, the filter mounting part 271 can rotate relative to the side end of the sewage liner assembly 22.

[0104] Specifically, one of the filter mounting portion 271 and the side end of the sewage liner assembly 22 is provided with a second stroke groove 2234. The other of the filter mounting portion 271 and the side end of the sewage liner assembly 22 is provided with a second stroke shaft 2713. The second stroke shaft 2713 is defined in the second stroke groove 2234. The second stroke groove 2234 and the second stroke groove 2234 are both extended along the first direction.

[0110] Fig. 20 is a first partial cross-sectional schematic diagram of an embodiment of a sewage tank of the present application in a second position; Fig.21 yes Fig. 20The structural schematic diagram of H is shown. The sewage tank 20 includes a sewage tank shell 21 and a sewage cover assembly (not shown in the figure). The sewage tank shell 21 is provided with a sewage installation port 2111. The sewage installation port 2111 provides an installation position for the sewage cover assembly. The sewage cover assembly is sealed and connected to the sewage installation port 2111. Among them, the sewage cover assembly can be sealed and connected to the sewage installation port 2111 through a sewage liner sealing ring 224, meeting the sealing requirements of the sewage tank 20, so that the sewage tank 20 can be used at any angle such as lying flat or standing upright. The above-mentioned sewage cover assembly is at least partially located inside the sewage tank shell 21 and at least partially located at the top of the sewage tank shell 21. Liner shafts 251 are provided on both sides of the sewage cover assembly. Among them, the liner shaft 251 can be detachable or fixed to both sides of the sewage cover assembly. As in the present embodiment, the liner shaft 251 is welded or integrally connected to the sewage cover assembly.

[0111] The sewage tank 20 also includes a liner handle assembly 26. The liner handle assembly 26 includes two liner rotating parts 261 and a liner handle part 262. The liner handle part 262 is connected between the two liner rotating parts 261. That is, one end of the liner handle part 262 is connected to one liner rotating part 261. Among them, one end of the liner handle part 262 is welded or integrally formed with one liner rotating part 261. The other end of the liner handle part 262 is connected to another liner rotating part 261. Among them, the other end of the liner handle part 262 is welded or integrally formed with another liner rotating part 261. By acting on the liner handle part 262, the liner handle part 262 acts together on the two liner rotating parts 261 to rotate, which can not only ensure the consistency of the movement of the two liner rotating parts 261; but also facilitate force gripping or grabbing, thereby further improving the user experience.

[0112] The liner rotating member 261 is at least partially located on the top surface of the sewage tank shell 21. That is, one liner rotating member 261 is at least partially located on one side of the top surface of the sewage tank shell 21; the other liner rotating member 261 is at least partially located on the other side of the top surface of the sewage tank shell 21. Among them, one side of the top surface of the sewage tank shell 21 can be the left top surface of the sewage tank shell 21; the other side of the top surface of the sewage tank shell 21 can be the right top surface of the sewage tank shell 21. The liner rotating member 261 is formed with a first motion groove 26121. That is, each liner rotating member 261 is formed with a first motion groove 26121. The liner rotating shaft 251 is located in the first motion groove 26121. That is, the liner rotating shaft 251 and the first motion groove 26121 rotate relative to each other.

[0113] By rotating the liner handle 262, the liner handle 262 acts together to rotate the two liner rotating parts 261, the liner rotating parts 261 rotate and squeeze the top surface of the sewage tank shell 21, and the liner rotating shaft 251 moves along the first movement groove 26121 until the liner rotating shaft 251 is away from the top surface of the sewage tank shell 21. At this time, the sewage upper cover assembly has a stroke of movement, thereby separating the seal between the sewage upper cover assembly and the sewage tank shell 21, and then the sewage upper cover assembly and the sewage tank shell 21 can be easily and completely separated by lifting the liner handle 262.

[0114] Through the cooperation of the sewage tank shell 21, the sewage cover assembly and the liner handle assembly 26, the seal between the sewage cover assembly and the sewage tank shell 21 can be separated, making it easy to remove the sewage cover assembly, thereby improving the user experience.

[0115] In some embodiments, the liner rotating member 261 has at least a first position and a second position. Fig.18 As shown, when the liner handle assembly 26 is in the first position, the liner rotating shaft 251 is located at the first end of the first movement groove 26121, and the liner handle member 262 is located on the upper surface of the sewage upper cover assembly. The first position may be the initial state of the liner rotating member 261, at which time the sewage upper cover assembly is sealed and connected to the sewage tank housing 21, the liner rotating member 261 is at least partially located on the top surface of the sewage tank housing 21, and the liner handle member 262 is located on the upper surface of the sewage upper cover assembly.

[0116] When the liner handle assembly 26 is in the second position, the liner rotating shaft 251 is away from the sewage tank shell 21 and moves along the first movement groove 26121, so that the sewage upper cover assembly is pushed out relative to the top of the sewage tank shell 21. Among them, the second position can be the state after the liner rotating member 261 rotates from the first position. During the movement of the above-mentioned liner handle assembly 26 from the first position to the second position, the liner rotating member 261 rotates relative to the top surface of the sewage tank shell 21, the liner rotating member 261 squeezes the top surface of the sewage tank shell 21, and the liner rotating shaft 251 moves along the first movement groove 26121, so that the sewage upper cover assembly has a stroke movement in the vertical direction, thereby separating the seal between the sewage upper cover assembly and the sewage tank shell 21, and then the sewage upper cover assembly and the sewage tank shell 21 can be easily and completely separated by lifting the liner handle member 262.

[0117] In some embodiments, the shape of the first motion groove 26121 is the same as the rotational motion path of the liner rotating member 261 relative to the top surface of the sewage tank housing 21, which can improve the smoothness of movement between the first motion groove 26121 and the liner rotating member 261, thereby reducing the risk of the liner rotating shaft 251 being stuck in the first motion groove 26121, and ensuring the smoothness of the sewage upper cover assembly being ejected relative to the top of the sewage tank housing 21. In this embodiment, the first motion groove 26121 is arranged in an arc shape.

[0118] See also Fig. 22 , Fig. 22 yes Fig.17 Schematic diagram of the structure of E. Figures 17 to 21 In some embodiments, a lining step portion 2113 is provided on the top surface of the sewage tank housing 21. The lining step portion 2113 can be detachable or fixed to the top surface of the sewage tank housing 21. As in the present embodiment, the lining step portion 2113 is welded or integrally formed on the top surface of the sewage tank housing 21. The number of lining step portions 2113 can be two. One lining step portion 2113 is provided on one side of the top surface of the sewage tank housing 21, and one lining step portion 2113 is located below one lining rotating member 261. Another lining step portion 2113 is provided on the other side of the top surface of the sewage tank housing 21, and another lining step portion 2113 is located below another lining rotating member 261.

[0119] The liner step portion 2113 is inclinedly provided with a liner abutment surface 21131. When the liner handle assembly 26 is in the first position, the liner rotating member 261 is at least partially located on the liner abutment surface 21131. When the liner rotating member 261 rotates relative to the top surface of the sewage tank shell 21, the liner rotating member 261 squeezes the liner abutment surface 21131, which not only makes the sewage upper cover assembly move in a certain stroke in the vertical direction, but also facilitates the separation of the seal between the sewage upper cover assembly and the sewage tank shell 21, thereby improving the user experience; and it can also improve the smoothness of the rotation of the liner rotating member 261 relative to the top surface of the sewage tank shell 21.

[0120] Specifically, the liner rotating member 261 is matched with the inclined surface of the liner abutment surface 21131. Among them, the liner rotating member 261 is inclinedly provided with a liner inclined surface 26123. The liner inclined surface 26123 is matched with the inclined surface of the liner abutment surface 21131. When the liner rotating member 261 rotates relative to the top surface of the sewage tank shell 21, the liner inclined surface 26123 of the liner rotating member 261 squeezes the liner abutment surface 21131, which not only makes the sewage upper cover assembly move in a certain stroke in the vertical direction, but also facilitates the separation of the seal between the sewage upper cover assembly and the sewage tank shell 21, thereby improving the user experience; and it can also improve the smoothness of the rotation of the liner rotating member 261, thereby reducing the movement resistance, etc., thereby improving the user experience.

[0121] See also Fig.23 , Fig.24 as well as Fig.25 , Fig.23 is a side view of a liner handle assembly in an embodiment of a sewage tank of the present application; Fig.24 is a second partial cross-sectional schematic diagram of an embodiment of a sewage tank of the present application in a second position; Fig.25 yes Fig.24 Schematic diagram of the structure of J. Figures 17 to 22 In some embodiments, the liner rotating member 261 includes a second movement groove 26122. The second movement groove 26122 is connected to the first movement groove 26121. The liner rotating shaft 251 moves between the first movement groove 26121 and the second movement groove 26122. The liner rotating shaft 251 can move along the first movement groove 26121 to the second movement groove 26122; or the liner rotating shaft 251 can move along the second movement groove 26122 to the first movement groove 26121.

[0122] After the sewage upper cover assembly and the sewage tank shell 21 are sealed and separated, the liner rotating member 261 is continued to be lifted, and the liner rotating shaft 251 is rotated to the second moving groove 26122, and then the sewage upper cover assembly and the sewage tank shell 21 can be easily and completely separated.

[0123] After the sewage cover assembly is sealed and installed on the sewage tank housing 21, the liner rotating member 261 is moved, and when the liner rotating member 261 falls, it moves along the second movement groove 26122 to the first movement groove 26121 under its own gravity to move and reset. Alternatively, when assembled with the floor scrubber body, the liner handle assembly 26 can be reset to the first movement groove 26121 under a slight horizontal action.

[0124] Through the cooperation between the first moving groove 26121 and the second moving groove 26122, the lining shaft 251 can move between the first moving groove 26121 and the second moving groove 26122 of the lining rotating part 261, and the moving range is increased, which can not only easily realize the sealed separation between the sewage upper cover assembly and the sewage tank shell 21, but also effectively avoid the occurrence of motion interference, and can realize the automatic and effective resetting of the lining rotating part 261, thereby avoiding the phenomenon that the sewage upper cover assembly is sealed and installed to the sewage tank shell 21 and is stuck after the lining rotating part 261 is lifted.

[0125] See also Fig.26 , Fig.26 Schematic diagram of the structure of the liner handle assembly in one embodiment of the sewage tank of the present application. Figures 17 to 25In some embodiments, the first movement groove 26121 and the second movement groove 26122 are arranged in an arc shape. The first movement groove 26121 may be, but not limited to, an arc shape; the second movement groove 26122 may be, but not limited to, an arc shape or a circle shape. By assembling and combining the first movement groove 26121 and the second movement groove 26122, it is not only possible to easily achieve the sealed separation between the sewage upper cover assembly and the sewage tank housing 21, thereby improving the user experience; it is also possible to effectively avoid the occurrence of motion interference, and to achieve the automatic and effective resetting of the liner rotating member 261.

[0126] In some other embodiments, the liner handle assembly 26 includes two liner rotating parts 261, but no liner handle part 262. There are at least two ways to release the seal between the sewage upper cover assembly and the sewage tank shell 21. The first way: act on the two liner rotating parts 261 together to simultaneously push both side ends of the sewage upper cover assembly out relative to the top of the sewage tank shell 21. The second way: first act on one liner rotating part 261 to push one side end of the sewage upper cover assembly out relative to one side of the top of the sewage tank shell 21; then act on the other liner rotating part 261 to push the other side end of the sewage upper cover assembly out relative to the other side of the top of the sewage tank shell 21.

[0127] The above-mentioned liner handle member 262 rotates; or the two liner rotating members 261 rotate independently or together, which can be manually operated by the user or automatically operated by the liner drive assembly (not shown in the figure). In one embodiment, the liner handle assembly 26 also includes a liner drive assembly. One end of the liner drive assembly is connected to a liner rotating member 261; the other end of the liner drive assembly is connected to another liner rotating member 261. The liner drive assembly simultaneously drives the liner rotating member 261 to move so that the sewage upper cover assembly is ejected relative to the sewage tank shell 21. In another embodiment, the liner drive assembly is connected to the liner handle member 262. The liner drive assembly drives the liner handle member 262 to move so that the sewage upper cover assembly is ejected relative to the sewage tank shell 21. The above-mentioned liner drive assembly can be, but is not limited to, motor driven, gear driven, and worm gear driven. The above-mentioned liner drive assembly can improve the automaticity of the sewage upper cover assembly ejecting relative to the sewage tank shell 21.

[0128] In some embodiments, two liner rotating parts 261 are symmetrically arranged at both ends of the liner handle 262. The liner rotating shafts 251 are symmetrically arranged on both sides of the sewage upper cover assembly. Among them, the two liner rotating parts 261 and the two liner rotating shafts 251 are symmetrically arranged. When the liner handle 262 is rotated, the liner handle can drive the liner rotating part 261 to rotate, which is more conducive to the two sides of the sewage upper cover assembly to be ejected relative to the two sides of the top of the sewage tank shell 21 at the same time, further improving the force uniformity of the separation of the sewage upper cover assembly, thereby further improving the user experience.

[0129] In some embodiments, the sewage upper cover assembly includes a sewage liner assembly 22 and a sewage tank upper cover 25. The sewage liner assembly 22 is sealed and connected to the sewage installation port 2111. The sewage tank upper cover 25 is connected to the sewage liner assembly 22. The sewage tank upper cover 25 and the sewage liner assembly 22 are detachably or fixedly connected. The sewage tank upper cover 25 can move with the sewage liner assembly 22. When the sewage liner assembly 22 is taken out or installed relative to the sewage tank housing 21, the sewage tank upper cover 25 is also taken out or installed with the sewage liner assembly 22. The above-mentioned liner rotating shaft 251 is arranged on both sides of the sewage tank upper cover 25. The liner rotating shaft 251 is welded or integrally formed on the sewage tank upper cover 25.

There are at least two ways to set the joint piece 23 between the sewage inlet pipe 212 and the sewage chamber 221. For example, the first way to set the joint piece 23 is as follows. The first joint part 232 is connected to the end of the sewage inlet pipe 212. The connection method can be but not limited to snap-on and plug-in, and then welding. The second joint part 233 is detachable from the sewage chamber 221. The detachable method can be but not limited to snap-on, plug-in and abutment. When the sewage lining assembly 22 is taken out from the sewage tank shell 21, the second joint part 233 of the joint piece 23 is disconnected from the sewage chamber 221, and the joint piece 23 is connected to the end of the sewage inlet pipe 212. When the sewage lining assembly 22 is installed in the sewage tank shell 21, the second joint part 233 of the joint piece 23 is connected to the sewage chamber 221.

[0148] In some embodiments, the second joint portion 233 and the dirt-collecting cavity 221 are in interference sealing contact, which ensures the detachable connection between the second joint portion 233 and the dirt-collecting cavity 221 and also ensures the sealing between the second joint portion 233 and the dirt-collecting cavity 221. The above sealing contact method may be, but is not limited to, through a joint sealing ring.

[0149] In a specific embodiment, a first joint sealing portion 2331 is provided on the side of the dirt-falling cavity 221 or the second joint portion 233.
