Detailed Implementation

[0071] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0072] The floor scrubbing machine provided by the present invention will be described in detail below with reference to the embodiments.

[0073] Please see Figure 1 , Figure 1 This is an exploded view of an embodiment of the floor scrubber of this application. This application provides a floor scrubber. The floor scrubber 100 includes at least a floor scrubber body 30, a floor brush assembly 10, a handle assembly 40, and a wastewater tank 20. The floor scrubber body 30 provides mounting positions for the floor brush assembly 10, the handle assembly 40, and the wastewater tank 20. The floor brush assembly 10 is rotatable at the lower part of the floor scrubber body 30, allowing it to lie flat or stand upright relative to the floor scrubber body 30. The floor brush assembly 10 and the floor scrubber body 30 are rotatably connected via a floor brush shaft. The handle assembly 40 is detachable from the upper part of the floor scrubber body 30. The handle assembly 40 can be inserted into or snapped into the upper part of the floor scrubber body 30 for fixation. The wastewater tank 20 is detachable from the rear part of the floor scrubber body 30. The wastewater tank 20 can be snapped into the rear part of the floor scrubber body 30. The wastewater tank 20 is distributed on the rear side of the floor scrubber body 30. When the floor scrubber 100 is in use, the wastewater tank 20 is closer to the ground. As a result, the aforementioned floor brush assembly 10, handle assembly 40, and wastewater tank 20 can all be disassembled for easy installation and disassembly, thereby improving the user experience.

[0074] Please see Figure 2 , Figure 3 as well as Figure 4 , Figure 2 This is a schematic diagram of the structure of a wastewater tank according to an embodiment of this application; Figure 3 This is a cross-sectional schematic diagram of an embodiment of the wastewater tank of this application; Figure 4 This is a partial cross-sectional schematic diagram of an embodiment of the wastewater tank of this application in a first moving position. The wastewater tank 20 includes a wastewater tank shell 21 and a wastewater liner assembly 22. The wastewater tank shell 21 has a wastewater cavity 211 with a wastewater installation port 2111. The wastewater installation port 2111 provides an installation position for the wastewater liner assembly 22. The wastewater liner assembly 22 is sealed to the wastewater installation port 2111. The wastewater liner assembly 22 can be sealed to the wastewater installation port 2111 via a wastewater liner sealing ring 224, satisfying the sealing requirements of the wastewater tank 20, so that the wastewater tank 20 can be used at any angle, such as lying flat or standing upright.

[0075] The wastewater tank 20 also includes a filter basket assembly 27. The filter basket assembly 27 is located within the wastewater chamber 211. The filter basket assembly 27 is used to filter substances drawn into the wastewater inlet pipe 212, causing larger particles to accumulate within the filter basket assembly 27, thereby achieving dry-wet separation. The filter basket assembly 27 includes a filter mounting part 271 and a filter part 272. The filter mounting part 271 and the filter part 272 are connected. The filter mounting part 271 and the filter part 272 are detachably or fixedly connected. In this embodiment, the filter mounting part 271 and the filter part 272 are welded or integrally formed. The filter mounting part 271 serves an installation function; while the filter part 272 is used to filter and accumulate larger particles. Larger particles can be, but are not limited to, solid substances and insoluble substances.

[0076] Please see Figure 5 , Figure 6 as well as Figure 7 , Figure 5 This is a partial structural schematic diagram of an embodiment of the sewage tank of this application in the second moving position; Figure 6 yes Figure 4 The structural diagram of A shown below; Figure 7 This is a partial cross-sectional view of a wastewater tank in a second moving position according to an embodiment of this application. The filter mounting part 271 is releasably locked and rotatable at the side end of the wastewater liner assembly 22. Specifically, the filter mounting part 271 is releasably locked at the side end of the wastewater liner assembly 22. This can be achieved by locking the filter mounting part 271 at the side end of the wastewater liner assembly 22, or by disconnecting the filter mounting part 271 from the side end of the wastewater liner assembly 22. Additionally, the filter mounting part 271 is rotatable at the side end of the wastewater liner assembly 22. When the filter mounting part 271 is disconnected from the side end of the wastewater liner assembly 22, the filter mounting part 271 can rotate relative to the side end of the wastewater liner assembly 22 by a certain angle, wherein the filter part 272 rotates with the filter mounting part 271 by a certain angle. The filter part 272 is provided with filter holes 2721. The filter holes 2721 are used for filtration. The number and shape of the filter holes 2721 can be determined according to actual needs and are not limited here. The locking method described above can be, but is not limited to, snap-fit ​​and plug-in connections. The rotation method can be, but is not limited to, pivoting, rotation, and hinge.

[0077] The filter basket assembly 27 has at least a first moving position and a second moving position. When the filter basket assembly 27 is in the first moving position, the filter mounting part 271 can be locked to the side end of the sewage liner assembly 22, and the filter part 272 is located inside the sewage chamber 211. The aforementioned first moving position can be the initial position, that is, the entire filter basket assembly 27 is located inside the sewage chamber 211 and cannot move. The filter part 272 is used for dry and wet separation of the inhaled material, separating larger inhaled particles so that the larger inhaled particles accumulate on the filter part 272.

[0078] With the filter basket assembly 27 in the second moving position, the filter mounting part 271 is unlocked from the wastewater liner assembly 22, and then the filter mounting part 271 rotates relative to the wastewater liner assembly 22. When it is necessary to clean the suction material in the wastewater tank 20, the wastewater liner assembly 22 is removed from the wastewater tank housing 21. At this time, the filter basket assembly 27 is rotated to the second moving position. This second moving position can increase the opening of the filter basket assembly 27 and tilt it downward, making it easier to clean the suction material accumulated on the filter part 272, thereby improving the user experience.

[0079] Through the combined action of the wastewater tank shell 21, the wastewater liner assembly 22, and the filter basket assembly 27, the filter basket assembly 27 has at least a first moving position and a second moving position. When the filter basket assembly 27 is in the first moving position, the filter section 272 is used for dry and wet separation of the inhaled material, separating larger inhaled particles so that these larger particles accumulate on the filter section 272. When the filter basket assembly 27 is in the second moving position, this second moving position increases the opening of the filter basket assembly 27 and tilts it downwards, facilitating the cleaning of accumulated inhaled material on the filter section 272, thereby improving the user experience.

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

[0081] The upper part of the wastewater button assembly 28 is snapped onto the upper part of the floor scrubber body 30. The lower part of the wastewater button assembly 28 is releasably abutted against the filter mounting part 271. The wastewater button assembly 28 of the wastewater tank 20 is releasably snapped onto the floor scrubber body 30. This wastewater button assembly 28 is used not only to release the snap-fit ​​between the wastewater tank 20 and the floor scrubber body 30, but also to release the locking connection between the filter basket assembly 27 and the wastewater liner assembly 22, thus realizing the reusability of the wastewater button assembly 28.

[0082] The aforementioned wastewater button assembly 28 is equipped with a button catch handle 2815. The wastewater tank 20 cover is provided with a button catch handle groove 255. The button catch handle groove 255 corresponds to the button catch handle 2815. The user disconnects the wastewater tank 20 from the floor scrubber body 30 by pressing the button catch handle 2815. Then, the user continues to apply pressure to the button portion 2812 of the button assembly 281 or the button catch handle 2815, causing the filter basket assembly 27 to be in a second moving position, facilitating the cleaning of sucked-up materials.

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

[0084] The filter mounting portion 271 and the side end of the wastewater liner assembly 22 are releasably locked together, wherein the locking method may be, but is not limited to, snap-fit ​​or plug-in. In a specific embodiment, the filter mounting portion 271 and the side end of the wastewater liner assembly 22 are releasably snap-fit ​​connected. For example, the filter mounting portion 271 is provided with a filter snap-fit ​​portion 2711. The filter snap-fit ​​portion 2711 is detachable or fixed to the filter mounting portion 271. In this embodiment, the filter snap-fit ​​portion 2711 is welded or integrally formed to the filter mounting portion 271. The side end of the wastewater liner assembly 22 is provided with a liner snap-fit ​​groove 2231. When the filter basket assembly 27 is in the first moving position, the filter snap-fit ​​portion 2711 snaps into the liner snap-fit ​​groove 2231. When the filter basket assembly 27 is in the second moving position, the filter snap-fit ​​portion 2711 is released from the liner snap-fit ​​groove 2231.

[0085] By cooperating with the filter clip 2711 and the inner liner clip groove 2231, a releasable locking connection is achieved between the filter installation part 271 and the side end of the sewage inner liner assembly 22. The structure is simple and easy to operate.

[0086] The engagement between the filter clip 2711 and the inner liner clip groove 2231 can be released in various ways. For example, manually or automatically. The manual and automatic methods for releasing the engagement will be explained in detail below.

[0087] In one embodiment, a filter basket latch handle (not shown in the figure) is provided on the side of the filter latch 2711 opposite to the inner liner latch groove 2231. The filter basket latch handle is welded or integrally formed on the side of the filter latch 2711 opposite to the inner liner latch groove 2231. The filter basket latch handle allows the user to manually release the latch between the filter latch 2711 and the inner liner latch groove 2231, thereby releasing the latch connection between the filter basket assembly 27 and the wastewater liner assembly 22, facilitating subsequent rotation of the filter basket assembly 27 relative to the wastewater liner assembly 22. The number and shape of the filter basket latch handles are not limited, as long as they are convenient for user operation.

[0088] Please see Figure 8 , Figure 9, Figure 10 as well as Figure 11 , Figure 8 This is a schematic diagram of the filter basket assembly in one embodiment of the wastewater tank of this application; Figure 9 yes Figure 8 The diagram shows the structure of C. Figure 10 This is a schematic diagram of the structure of the sewage lining assembly in one embodiment of the sewage tank of this application; Figure 11 yes Figure 10 The diagram shows the structure of D. (Combined with...) Figures 1 to 7 In some embodiments, the wastewater liner assembly 22 includes a wastewater liner 223. A wastewater button assembly 28 is disposed between the wastewater tank cover 25 and the wastewater liner 223. The wastewater button assembly 28 is detachable between the wastewater tank cover 25 and the wastewater liner 223. The wastewater button assembly 28 can be released from contact with the filter latch 2711. When the wastewater button assembly 28 is released from contact with the filter latch 2711, there is no contact between them, and the filter basket assembly 27 is in a first moving position. When the wastewater button assembly 28 contacts the filter latch 2711, the filter latch 2711 is released from contact with the liner latch groove 2231, and then the filter basket assembly 27 rotates relative to the side of the wastewater liner assembly 22 to place the filter basket assembly 27 in a second moving position.

[0089] The aforementioned wastewater button assembly 28 allows the user to automatically release the engagement between the filter latch 2711 and the liner latch groove 2231, thereby automatically releasing the engagement between the filter basket assembly 27 and the wastewater liner assembly 22, facilitating the rotation of the filter basket assembly 27 relative to the wastewater liner assembly 22. The aforementioned wastewater button assembly 28 can be driven by, but is not limited to, a squeeze drive or a push drive.

[0090] Please see Figure 12 , Figure 13 , Figure 14 as well as Figure 15 , Figure 12 This is a schematic diagram of a second partial cross-section of an embodiment of the sewage tank of this application in a second moving position; Figure 13 This is a partial schematic diagram of an embodiment of the wastewater tank of this application; Figure 14 This is a schematic diagram of the button component in one embodiment of the sewage tank of this application; Figure 15 This is a structural schematic diagram of the top rod member in one embodiment of the sewage tank of this application. (Combined with...) Figures 1 to 11Specifically, a button mounting space 254 is formed between the wastewater tank cover 25 and the wastewater liner 223. The button mounting space 254 provides a mounting space for the wastewater button assembly 28. The wastewater button assembly 28 includes a button 281 and a top rod 282. The button 281 is disposed within the button mounting space 254. The button 281 at least partially protrudes from the surface of the wastewater tank cover 25 for easy pressing operation by the user. The top rod 282 at least partially passes through the button mounting space 254; simultaneously, the top rod 282 is telescopically connected to the button 281 along a first direction. The bottom of the top rod 282 releasably abuts against the filter latch 2711.

[0091] When the button 281 is pressed, it acts on the top rod 282, which abuts against the filter locking part 2711, thereby disengaging the filter locking part 2711 from the inner liner locking groove 2231 and releasing the connection between the filter mounting part 271 and the side end of the sewage liner assembly 22. When the button 281 is not under pressure, the top rod 282 and the button 281 return to their original positions. Through the cooperation of the button mounting space 254, the button 281, and the top rod 282, not only is automatic unlocking between the filter locking part 2711 and the inner liner locking groove 2231 achieved, but the structure is also simple and easy to operate.

[0092] Further, the button component 281 includes a button body 2811. A button portion 2812 is provided on the upper part of the button body 2811. The button portion 2812 protrudes from the surface of the sewage tank cover 25. By pressing the button portion 2812, the user can drive the button component 281 to move downward in a first direction. A push rod travel groove 2813 and a button groove 2814 are provided on the lower part of the button body 2811. The push rod travel groove 2813 and the button groove 2814 are connected. The push rod component 282 includes a push rod travel shaft 2821 and a top plate 2823. The push rod travel shaft 2821 is provided on the top plate 2823. Both the push rod travel shaft 2821 and the push rod travel groove 2813 extend in the first direction. The push rod travel shaft 2821 is located within the push rod travel groove 2813. A push rod engaging portion 2822 is provided on the outer periphery of the push rod travel shaft 2821. The push rod locking part 2822 can move up and down along the button groove 2814. The push rod travel shaft 2821 can be limited to move up and down in the first direction via the button groove 2814. The bottom of the top plate 2823 can be releasably engaged with the filter locking part 2711.

[0093] Through the combined action of the button body 2811, button portion 2812, push rod travel groove 2813, button groove 2814, push rod travel shaft 2821, and top plate 2823, the stability of the sewage button assembly 28 acting on the filter latching portion 2711 is improved. In this embodiment, the button portion 2812 is provided on the upper part of the button body 2811. Two push rod travel grooves 2813 are provided on the lower part of the button body 2811. The push rod member 282 includes two push rod travel shafts 2821. The push rod travel shafts 2821 are located within the corresponding push rod travel grooves 2813. The button member 281 is provided with the aforementioned button handle portion 2815.

[0094] Additionally, the wastewater button assembly 28 also includes a button spring element 283. The button spring element 283 is disposed between the lower part of the button element 281 and the wastewater liner 223. The button spring element 283 has a certain elasticity, enabling the button element 281 to return to its original shape. The button spring element 283 can be, but is not limited to, a button spring (not shown in the figure).

[0095] In some other embodiments, a filter basket handle is provided on the side of the filter clip 2711 opposite to the inner liner clip groove 2231. Meanwhile, a wastewater button assembly 28 is disposed between the wastewater tank cover 25 and the wastewater liner 223. The wastewater button assembly 28 is releasable and abuts against the filter clip 2711. The filter basket assembly 27 and the side of the wastewater liner assembly 22 can be released manually or automatically, depending on the user's needs; no limitation is made here.

[0096] Please see Figure 16 , Figure 16 yes Figure 6 The structural diagram of B shown is illustrated. (Combined with...) Figures 1 to 15 In some embodiments, a liner snap-fit ​​portion 2232 is provided on the side end of the wastewater liner assembly 22. The liner snap-fit ​​portion 2232 is welded or integrally formed on the side end of the wastewater liner assembly 22. A liner snap-fit ​​groove 2231 is formed on the upper part of the liner snap-fit ​​portion 2232. A liner inclined surface 22321 is provided on the end of the liner snap-fit ​​portion 2232 facing away from the wastewater liner assembly 22. A filter inclined surface 27111 is provided on the upper side of the filter snap-fit ​​portion 2711 facing the wastewater liner assembly 22. When the filter basket assembly 27 changes from the second movement position to the first movement position, the user can manually move the filter mounting part 271 upward in the first direction and continue to push the filter mounting part 271 upward. At this time, the filter inclined surface 27111 can slide on the inner lining inclined surface 22321, and then the filter snap-fit ​​part 2711 snaps into the inner lining snap-fit ​​groove 2231, realizing the snap-fit ​​connection between the filter mounting part 271 and the side end of the sewage inner lining assembly 22.

[0097] Through the combined action of the aforementioned inner lining inclined surface 22321 and filter inclined surface 27111, not only is it easier for the filter basket assembly 27 to move from the second moving position to the first moving position, improving assembly efficiency, but it also reduces movement resistance, thereby improving the user experience. The aforementioned filter inclined surface 27111 and inner lining inclined surface 22321 have the same inclination direction. For example, the filter inclined surface 27111 extends downwards.

[0098] In some embodiments, the two sides of the filter mounting portion 271 and the two sides of the wastewater liner assembly 22 are connected by a first travel groove 2712 and a first travel shaft 2233, and the first travel groove 2712 and the first travel shaft 2233 extend along a first direction, causing the filter mounting portion 271 to move downward along the first direction by a certain stroke, increasing the rotation angle of the filter mounting portion 271 relative to the wastewater liner assembly 22, thereby facilitating the cleaning of the sucked-in material in the filter basket assembly 27. The aforementioned first direction may be, but is not limited to, the vertical direction.

[0099] Specifically, a first travel groove 2712 is provided on one of the two sides of the filter mounting part 271 and the two sides of the sewage liner assembly 22. A first travel shaft 2233 is provided on the other of the two sides of the filter mounting part 271 and the two sides of the sewage liner assembly 22. The first travel groove 2712 extends along a first direction. The first travel shaft 2233 extends along a second direction. The first travel shaft 2233 moves along the first travel groove 2712, that is, the first travel shaft 2233 can move vertically upward or vertically downward. At the same time, after the first travel shaft 2233 moves to a suitable position along the first travel groove 2712, the first travel shaft 2233 can rotate relative to the first travel groove 2712 by a certain angle. The first direction and the second direction are different.

[0100] In this embodiment, first travel grooves 2712 are respectively provided on both sides of the filter mounting part 271. First travel shafts 2233 are respectively provided on both sides of the wastewater liner assembly 22. The first travel shafts 2233 are welded or integrally formed on both sides of the wastewater liner assembly 22. The first travel shafts 2233 on the side of the wastewater liner assembly 22 move and rotate along the first travel grooves 2712 of the filter mounting part 271.

[0101] In other embodiments, a first stroke shaft 2233 is provided on both sides of the filter mounting portion 271. The first stroke shaft 2233 is welded or integrally formed on both sides of the filter mounting portion 271. A first stroke groove 2712 is provided on both sides of the wastewater liner assembly 22. The first stroke shaft 2233 of the filter mounting portion 271 moves and rotates along the first stroke groove 2712 on the side of the wastewater liner assembly 22.

[0102] The aforementioned filter latching portion 2711 and inner liner latching groove 2231 are located between the mating positions of the two first stroke grooves 2712 and the first stroke shaft 2233. In this embodiment, the mating positions of the two first stroke grooves 2712 and the first stroke shaft 2233 are symmetrically arranged at the mating positions of the filter latching portion 2711 and the inner liner latching groove 2231. When the filter mounting portion 271 is provided with first stroke shafts 2233 on both sides, the two first stroke shafts 2233 are symmetrically arranged on both sides of the filter latching portion 2711. The first stroke shaft 2233 may be, but is not limited to, a stroke pin (not shown in the figure). The first stroke groove 2712 may be, but is not limited to, a stroke slot (not shown in the figure).

[0103] In some embodiments, the filter mounting portion 271 and the side end of the wastewater liner assembly 22 are mutually constrained and fitted by a second stroke groove 2234 and a second stroke shaft 2713. Both the second stroke groove 2234 and the second stroke shaft 2234 extend along a first direction, making the downward movement of the filter mounting portion 271 along the first direction more stable, thereby reducing the lateral swaying of the filter mounting portion 271 along the first direction. When the vertical constraint between the second stroke groove 2234 and the second stroke shaft 2713 is released between the filter mounting portion 271 and the wastewater liner assembly 22, the filter mounting portion 271 can rotate relative to the side end of the wastewater liner assembly 22.

[0104] Specifically, one of the filter mounting section 271 and the wastewater liner assembly 22 side end is provided with a second travel groove 2234. The other of the filter mounting section 271 and the wastewater liner assembly 22 side end is provided with a second travel shaft 2713. The second travel shaft 2713 is confined within the second travel groove 2234. Both the second travel groove 2234 and the second travel groove 2234 extend along a first direction.

[0105] In this embodiment, the filter mounting portion 271 is provided with a second stroke shaft 2713. The second stroke shaft 2713 is welded to or integrally formed into the filter mounting portion 271. A second stroke groove 2234 is provided on the side end of the wastewater liner assembly 22. The second stroke shaft 2713 of the filter mounting portion 271 is confined within the second stroke groove 2234 on the side end of the wastewater liner assembly 22. That is, the second stroke shaft 2713 moves vertically along the second stroke groove 2234.

[0106] As in other embodiments, the filter mounting portion 271 is provided with a second travel groove 2234. A second travel shaft 2713 is provided on the side end of the wastewater liner assembly 22. The second travel shaft 2713 is welded or integrally formed on the side end of the wastewater liner assembly 22. The second travel shaft 2713 on the side end of the wastewater liner assembly 22 is confined within the second travel groove 2234 of the filter mounting portion 271. That is, the second travel groove 2234 moves vertically relative to the second travel shaft 2713.

[0107] The number of the aforementioned second stroke shafts 2713 and second stroke grooves 2234 can be, but is not limited to, one, two, or three. In this embodiment, both the number of second stroke shafts 2713 and the number of second stroke grooves 2234 are two. The mating positions of the two first stroke shafts 2233 and the two first stroke grooves 2712 are located between the mating positions of the two second stroke shafts 2713 and the two second stroke grooves 2234. When the filter mounting portion 271 is provided with second stroke shafts 2713 on both sides, the two second stroke shafts 2713 are symmetrically arranged on both sides of the filter snap-fit ​​portion 2711; simultaneously, the two second stroke shafts 2713 are symmetrically arranged on both sides of the two first stroke shafts 2233. The second stroke shaft 2713 can be, but is not limited to, a cross-shaped rib (not shown in the figure). The second stroke groove 2234 can be, but is not limited to, a stroke sleeve (not shown in the figure).

[0108] In some embodiments, the wastewater liner assembly 22 includes a wastewater discharge chamber 221. The wastewater discharge chamber 221 can communicate with the wastewater inlet pipe 212 in the wastewater tank 20. Moisture, air, and other substances in the wastewater inlet pipe 212 enter the wastewater discharge chamber 221. Because the wastewater discharge chamber 221 is connected to the wastewater chamber 211, the substances in the wastewater inlet pipe 212 pass through the wastewater discharge chamber 221 and enter the wastewater chamber 211. When the filter basket assembly 27 is in the first moving position, the wastewater discharge outlet (not shown in the figure) of the wastewater discharge chamber 221 faces the filter section 272, which is used for dry and wet separation of the inhaled substances, separating larger inhaled particles so that the larger inhaled particles accumulate on the filter section 272. The filter section 272 is provided with a filter groove 2722. The filter groove 2722 is used to avoid the wastewater inlet pipe 212 so that the filter section 272 fits against the side wall of the wastewater chamber 211.

[0109] Please see Figure 17 , Figure 18 , Figure 19 , Figure 20 as well as Figure 21 , Figure 17 This is an exploded schematic diagram of an embodiment of the sewage tank of this application; Figure 16 This is a partial cross-sectional schematic diagram of a wastewater tank in a first position according to an embodiment of this application; Figure 19 yes Figure 18 The diagram shows the structure of G.

[0110] Figure 20 This is a partial cross-sectional schematic diagram of a wastewater tank in a second position according to an embodiment of this application; Figure 21 yes Figure 20The diagram shows the structure of H. The sewage tank 20 includes a sewage tank shell 21 and a sewage cover assembly (not shown in the diagram). The sewage tank shell 21 has 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 to the sewage installation port 2111. The sewage cover assembly can be sealed to the sewage installation port 2111 via a sewage inner lining sealing ring 224, meeting the sealing requirements of the sewage tank 20 and allowing the sewage tank 20 to be used at any angle, whether lying flat or upright. The sewage cover assembly is at least partially located inside the sewage tank shell 21 and at least partially located on the top of the sewage tank shell 21. Inner lining rotating shafts 251 are provided on both sides of the sewage cover assembly. The inner lining rotating shafts 251 are detachable or fixed to both sides of the sewage cover assembly. In this embodiment, the inner lining rotating shafts 251 are welded to or integrally formed with the sewage cover assembly.

[0111] The wastewater tank 20 also includes an inner lining handle assembly 26. The inner lining handle assembly 26 includes two inner lining rotating parts 261 and an inner lining handle 262. The inner lining handle 262 is connected between the two inner lining rotating parts 261. Specifically, one end of the inner lining handle 262 is connected to one inner lining rotating part 261. One end of the inner lining handle 262 is welded to or integrally formed with one inner lining rotating part 261. The other end of the inner lining handle 262 is connected to the other inner lining rotating part 261. The other end of the inner lining handle 262 is welded to or integrally formed with the other inner lining rotating part 261. By acting on the inner lining handle 262, the inner lining handle 262 collectively acts on the rotation of the two inner lining rotating parts 261, ensuring not only the consistency of movement of the two inner lining rotating parts 261 but also facilitating gripping or grasping, thereby further improving the user experience.

[0112] The inner lining rotating member 261 is at least partially located on the top surface of the sewage tank shell 21. Specifically, one inner lining rotating member 261 is at least partially located on one side of the top surface of the sewage tank shell 21; the other inner lining rotating member 261 is at least partially located on the other side of the top surface of the sewage tank shell 21. 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 inner lining rotating member 261 has a first movement groove 26121. The inner lining rotating shaft 251 is located in the first movement groove 26121. That is, the inner lining rotating shaft 251 and the first movement groove 26121 rotate relative to each other.

[0113] By rotating the inner lining handle 262, the inner lining handle 262 acts together to rotate the two inner lining rotating parts 261. The inner lining rotating parts 261 rotate and squeeze the top surface of the sewage tank shell 21. The inner lining rotating shaft 251 moves along the first moving groove 26121 until the inner lining rotating shaft 251 moves away from the top surface of the sewage tank shell 21. At this time, the sewage cover assembly has a certain stroke of movement, which makes the seal between the sewage cover assembly and the sewage tank shell 21 separate. Then, by lifting the inner lining handle 262, the sewage cover assembly and the sewage tank shell 21 can be easily and completely separated.

[0114] Through the combined action of the sewage tank shell 21, the sewage cover assembly, and the inner lining 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 and thus improving the user experience.

[0115] In some embodiments, the liner rotator 261 has at least a first position and a second position. For example... Figure 18 As shown, when the inner lining handle assembly 26 is in the first position, the inner lining rotating shaft 251 is located at the first end of the first moving groove 26121, and the inner lining handle 262 is located on the upper surface of the sewage cover assembly. The first position can be the initial state of the inner lining rotating component 261, at which time the sewage cover assembly is sealed to the sewage tank housing 21, the inner lining rotating component 261 is at least partially located on the top surface of the sewage tank housing 21, and the inner lining handle 262 is located on the upper surface of the sewage cover assembly.

[0116] When the inner liner handle assembly 26 is in the second position, the inner liner rotating shaft 251 moves away from the sewage tank housing 21 and along the first movement groove 26121, so that the sewage cover assembly is pushed out relative to the top of the sewage tank housing 21. The second position can be the state of the inner liner rotating member 261 after rotating from the first position. During the movement of the inner liner handle assembly 26 from the first position to the second position, the inner liner rotating member 261 rotates relative to the top surface of the sewage tank housing 21, pressing against the top surface of the sewage tank housing 21. The inner liner rotating shaft 251 moves along the first movement groove 26121, causing the sewage cover assembly to move vertically for a certain distance, thereby separating the seal between the sewage cover assembly and the sewage tank housing 21. Then, by lifting the inner liner handle 262, the sewage cover assembly and the sewage tank housing 21 can be easily and completely separated.

[0117] In some embodiments, the shape of the first motion groove 26121 is the same as the rotational path of the inner 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 inner liner rotating member 261, thereby reducing the risk of the inner liner rotating shaft 251 getting stuck in the first motion groove 26121 and ensuring the smooth ejection of the sewage cover assembly relative to the top of the sewage tank housing 21. As in this embodiment, the first motion groove 26121 is arc-shaped.

[0118] Please see Figure 22 , Figure 22 yes Figure 17 The diagram shows the structure of E. (Combined with...) Figures 17 to 21 In some embodiments, the top surface of the sewage tank shell 21 is provided with an inner lining step portion 2113. The inner lining step portion 2113 is detachable or fixed to the top surface of the sewage tank shell 21. In this embodiment, for example, the inner lining step portion 2113 is welded or integrally formed onto the top surface of the sewage tank shell 21. There can be two inner lining step portions 2113. One inner lining step portion 2113 is located on one side of the top surface of the sewage tank shell 21, and is positioned below an inner lining rotating member 261. The other inner lining step portion 2113 is located on the other side of the top surface of the sewage tank shell 21, and is positioned below another inner lining rotating member 261.

[0119] The inner lining step portion 2113 is inclinedly provided with an inner lining abutment surface 21131. When the inner lining handle assembly 26 is in the first position, the inner lining rotating member 261 is at least partially located on the inner lining abutment surface 21131. When the inner lining rotating member 261 rotates relative to the top surface of the sewage tank housing 21, the inner lining rotating member 261 presses against the inner lining abutment surface 21131, which not only allows the sewage cover assembly to move in the vertical direction for a certain period of time, but also facilitates the separation of the seal between the sewage cover assembly and the sewage tank housing 21, thereby improving the user experience; it also improves the smoothness of the rotation of the inner lining rotating member 261 relative to the top surface of the sewage tank housing 21.

[0120] Specifically, the inner liner rotating component 261 engages with the inclined surface of the inner liner abutment surface 21131. The inner liner rotating component 261 is provided with an inclined inner liner surface 26123. The inclined inner liner surface 26123 engages with the inclined inner liner abutment surface 21131. When the inner liner rotating component 261 rotates relative to the top surface of the sewage tank housing 21, the inclined inner liner surface 26123 of the inner liner rotating component 261 presses against the inner liner abutment surface 21131. This not only allows the sewage cover assembly to move vertically for a certain distance, but also facilitates the separation of the seal between the sewage cover assembly and the sewage tank housing 21, thereby improving the user experience. Furthermore, it also improves the smoothness of the rotation of the inner liner rotating component 261, thereby reducing movement resistance and further enhancing the user experience.

[0121] Please see Figure 23 , Figure 24 as well as Figure 25 , Figure 23 This is a side view of the inner lining handle assembly in one embodiment of the wastewater tank of this application; Figure 24 This is a schematic diagram of a second partial cross-section of an embodiment of the wastewater tank of this application in a second position; Figure 25 yes Figure 24 The diagram shows the structure of J. (Combined with...) Figures 17 to 22 In some embodiments, the liner rotating member 261 includes a second movement groove 26122. The second movement groove 26122 and the first movement groove 26121 are connected. 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 cover assembly and the sewage tank shell 21 are sealed and separated, the inner liner rotating part 261 is lifted and the inner liner rotating shaft 251 rotates to the second motion groove 26122, and then the sewage cover assembly and the sewage tank shell 21 can be completely separated.

[0123] After the wastewater cover assembly is sealed and installed on the wastewater tank housing 21, the inner liner rotating component 261 is turned. When the inner liner rotating component 261 falls, it will move along the second motion groove 26122 to the first motion groove 26121 under its own gravity and reset. Alternatively, the inner liner handle assembly 26 can be reset by slightly resetting it to the first motion groove 26121 under a slight horizontal force during assembly with the floor scrubber body.

[0124] With the cooperation of the first movement groove 26121 and the second movement groove 26122, the inner lining rotating shaft 251 can move between the first movement groove 26121 and the second movement groove 26122 of the inner lining rotating component 261. The range of motion is increased, which not only makes it easy to achieve the sealed separation between the sewage cover assembly and the sewage tank shell 21, but also effectively avoids the occurrence of movement interference. It can realize the automatic and effective reset of the inner lining rotating component 261, and avoid the phenomenon that the sewage cover assembly is stuck in the sewage tank shell 21 after the inner lining rotating component 261 is lifted.

[0125] Please see Figure 26 , Figure 26 This is a structural schematic diagram of the inner lining handle assembly in one embodiment of the sewage tank of this application. (Combined with...) Figures 17 to 25In some embodiments, the first motion groove 26121 and the second motion groove 26122 are arranged in an arc shape. The first motion groove 26121 may be, but is not limited to, arc-shaped; the second motion groove 26122 may be, but is not limited to, arc-shaped or circular, etc. By assembling the first motion groove 26121 and the second motion groove 26122 as described above, not only can the sealed separation between the sewage cover assembly and the sewage tank shell 21 be easily achieved, improving the user experience, but it also effectively avoids motion interference and enables the automatic and effective reset of the inner lining rotating component 261.

[0126] In some other embodiments, the inner lining handle assembly 26 includes two inner lining rotating members 261, but no inner lining handle member 262. There are at least two ways to release the seal between the sewage cover assembly and the sewage tank housing 21. The first method involves acting on both inner lining rotating members 261 simultaneously to push both ends of the sewage cover assembly out relative to the top of the sewage tank housing 21. The second method involves first acting on one inner lining rotating member 261 to push one end of the sewage cover assembly out relative to the top of the sewage tank housing 21; then acting on the other inner lining rotating member 261 to push the other end of the sewage cover assembly out relative to the other side of the top of the sewage tank housing 21.

[0127] The aforementioned inner lining handle 262 rotates; or the two inner lining rotating parts 261 rotate independently or together, which can be operated manually by the user or automatically by the inner lining drive assembly (not shown in the figure). In one embodiment, the inner lining handle assembly 26 further includes an inner lining drive assembly. One end of the inner lining drive assembly is connected to one inner lining rotating part 261; the other end of the inner lining drive assembly is connected to another inner lining rotating part 261. The inner lining drive assembly simultaneously drives the inner lining rotating parts 261 to move, causing the sewage cover assembly to push out relative to the sewage tank housing 21. In another embodiment, the inner lining drive assembly is connected to the inner lining handle 262. The inner lining drive assembly drives the inner lining handle 262 to move, causing the sewage cover assembly to push out relative to the sewage tank housing 21. The aforementioned inner lining drive assembly can be, but is not limited to, motor drive, gear drive, and worm gear drive. The aforementioned inner lining drive assembly improves the automaticity of pushing the sewage cover assembly out relative to the sewage tank housing 21.

[0128] In some embodiments, two inner liner rotating members 261 are symmetrically arranged at both ends of the inner liner handle member 262. Inner liner rotating shafts 251 are symmetrically arranged on both sides of the sewage cover assembly. The two inner liner rotating members 261 and the two inner liner rotating shafts 251 are all symmetrically arranged. When the inner liner handle member 262 is rotated, it drives the inner liner rotating members 261 to rotate, which facilitates the simultaneous ejection of both ends of the sewage cover assembly relative to the top sides of the sewage tank housing 21, further improving the uniformity of force distribution during the separation of the sewage cover assembly, thereby further enhancing the user experience.

[0129] In some embodiments, the wastewater cover assembly includes a wastewater liner assembly 22 and a wastewater tank cover 25. The wastewater liner assembly 22 is sealed to the wastewater installation port 2111. The wastewater tank cover 25 is connected to the wastewater liner assembly 22. The wastewater tank cover 25 and the wastewater liner assembly 22 are detachably or fixedly connected. The wastewater tank cover 25 can move with the wastewater liner assembly 22. When the wastewater liner assembly 22 is removed or installed relative to the wastewater tank housing 21, the wastewater tank cover 25 is also removed or installed along with the wastewater liner assembly 22. The aforementioned liner pivot 251 is provided on both sides of the wastewater tank cover 25. The liner pivot 251 is welded or integrally formed to the wastewater tank cover 25. Alternatively, the aforementioned liner pivot 251 is provided on both sides of the wastewater liner assembly 22. The liner pivot 251 is welded or integrally formed to the side of the wastewater liner assembly 22.

[0130] Please see Figure 27 and Figure 28 , Figure 27 This is a schematic diagram of the structure of the sewage tank cover in one embodiment of the sewage tank of this application; Figure 28 yes Figure 27 The diagram shows the structure of K. (Combined with...) Figures 17 to 26 In some embodiments, lining mounting grooves 252 are symmetrically provided on both sides of the sewage tank cover 25. The two sides of the sewage tank cover 25 can be located at the left and right ends of the sewage tank cover 25, respectively. The lining rotating shaft 251 is located on the side wall of the corresponding lining mounting groove 252. Because the lining rotating shaft 251 is located at the first movement groove 26121 or the second movement groove 26122 of the lining rotating member 261, the lining rotating member 261 is at least partially located within the lining mounting groove 252. The lining rotating member 261 can rotate clockwise relative to the sewage tank shell 21, so that the lining rotating member 261 changes from a first position to a second position.

[0131] The lining mounting groove 252 of the wastewater tank cover 25 not only provides an installation position for the lining shaft 251, but also accommodates at least part of the lining rotating parts 261, facilitating the subsequent installation of the wastewater tank 20 onto the floor scrubber body. Additionally, when the lining handle assembly 26 also includes a lining handle 262, the lining handle 262, located on the lining support 2114, also serves a certain storage function.

[0132] Please see Figure 29 , Figure 30 , Figure 31 as well as Figure 32 , Figure 29 yes Figure 17 The diagram shows the structure of F. Figure 30 yes Figure 20 The diagram shows the structure of I. Figure 31 This is a second partial cross-sectional schematic diagram of an embodiment of the sewage tank of this application in a first position; Figure 32 yes Figure 31 The diagram shows the structure of L. (Combined with...) Figures 17 to 28 In some embodiments, an inner lining support 2114 is provided on the top surface of the wastewater tank housing 21. The inner lining support 2114 is detachable or fixed to the top surface of the wastewater tank housing 21. In this embodiment, the inner lining support 2114 is welded or integrally formed onto the top surface of the wastewater tank housing 21. The inner lining support 2114 at least partially protrudes from the top surface of the wastewater tank housing 21. The inner lining support 2114 supports the inner lining handle 262, not only maintaining a small gap between the inner lining rotating member 261 and the top of the wastewater tank housing 21 for easy handling by the user, but also allowing the inner lining handle 262 to be stored above the inner lining support 2114, thus facilitating the overall installation of the wastewater tank 20 onto the floor scrubber body.

[0133] The aforementioned inner lining support 2114 can be located on the front side of the top surface of the sewage tank shell 21. The inner lining support 2114 can be, but is not limited to, square or isosceles trapezoidal shapes. When the inner lining support 2114 supports the inner lining handle 262, the sewage tank cover 25 is provided with an inner lining support groove 253. The inner lining support groove 253 is used to avoid the inner lining support 2114, so that the inner lining support 2114 can support the inner lining support groove 253, etc.

[0134] In some embodiments, the wastewater liner assembly 22 includes a wastewater liner 223 and a wastewater liner sealing ring 224. The wastewater liner sealing ring 224 is disposed on the upper outer periphery of the wastewater liner 223. The wastewater liner 223 is interference-sealed to the wastewater installation port 2111 by the wastewater liner sealing ring 224, so that the wastewater liner assembly 22 is sealed to the wastewater installation port 2111 of the wastewater tank housing 21. The wastewater tank cover 25 and the wastewater liner assembly 22 may be fastened together by screws, but not limited to, so that the wastewater tank cover 25 and the wastewater liner assembly 22 form a whole, and then interference-sealed onto the upper part of the wastewater tank housing 21, etc.

[0135] Please see Figure 33 , Figure 34 as well as Figure 35 , Figure 33 This is a partial cross-sectional schematic diagram of the first embodiment of the sewage tank of this application; Figure 34 yes Figure 33 The diagram shows the structure of M. Figure 35This is a partial schematic diagram of the first embodiment of the wastewater tank of this application. The wastewater tank shell 21 includes a wastewater cavity 211 and a wastewater inlet pipe 212. The wastewater inlet pipe 212 is disposed within the wastewater cavity 211. The wastewater inlet pipe 212 is integrally formed with the wastewater cavity 211; alternatively, the wastewater inlet pipe 212 and the wastewater cavity 211 are separately disposed. When wastewater is drawn in, the wastewater inlet pipe 212 draws in air and forms water vapor. The water vapor flows from the wastewater inlet pipe 212 into the wastewater cavity 211. The wastewater cavity 211 is used to store wastewater in the water vapor. The wastewater cavity 211 is provided with a wastewater installation port 2111. The wastewater installation port 2111 provides an installation position for the wastewater liner assembly 22. The wastewater liner assembly 22 is disposed on the wastewater tank shell 21. The wastewater liner assembly 22 is detachably and sealingly connected to the wastewater tank shell 21. When the wastewater liner assembly 22 is disposed on the wastewater tank shell 21, the wastewater liner assembly 22 is located at the wastewater installation port 2111. The wastewater liner assembly 22 includes a wastewater discharge chamber 221 and a return air section 222. The wastewater discharge chamber 221 is used for the inflow of water vapor. The return air section 222 is used for the outflow of air in the water vapor. The return air section 222 is located on the upper part of the wastewater discharge chamber 221. The wastewater discharge chamber 221 is connected to the wastewater chamber 211, and water vapor enters the wastewater chamber 211 from the wastewater discharge chamber 221.

[0136] The wastewater tank 20 also includes a connector 23. The connector 23 includes a connector pipe 231, a first connector portion 232, and a second connector portion 233. The first connector portion 232 is disposed at one end of the connector pipe 231. The second connector portion 233 is disposed at the other end of the connector pipe 231. The first connector portion 232 is detachable or fixed to one end of the connector pipe 231; the second connector portion 233 is detachable or fixed to the other end of the connector pipe 231. In this embodiment, the connector pipe 231, the first connector portion 232, and the second connector portion 233 are integrally formed or welded together.

[0137] The aforementioned connector 23 is disposed between the end of the sewage inlet pipe 212 and the sewage discharge chamber 221. The connector 23 serves a connecting function. There are at least two ways in which the connector 23 can be disposed between the sewage inlet pipe 212 and the sewage discharge chamber 221. For example, the first way the connector 23 can be disposed is as follows: The first connector portion 232 is connected to the end of the sewage inlet pipe 212. The connection method can be, but is not limited to, snap-fit, insertion, and welding. The second connector portion 233 is detachable from the sewage discharge chamber 221. The detachable method can be, but is not limited to, snap-fit, insertion, and abutment. When the sewage liner assembly 22 is removed from the sewage tank shell 21, the second connector portion 233 of the connector 23 is disconnected from the sewage discharge chamber 221, and the connector 23 is connected to the end of the sewage inlet pipe 212. When the sewage liner assembly 22 is installed on the sewage tank shell 21, the second connector portion 233 of the connector 23 is connected to the sewage discharge chamber 221.

[0138] The second type of connector 23 is configured as follows: The first connector portion 232 is detachable from the end of the sewage inlet pipe 212. Detachment can be achieved through, but is not limited to, snap-fit, plug-in, or abutment. The second connector portion 233 is connected to the sewage discharge chamber 221. The connection can be achieved through, but is not limited to, snap-fit, plug-in, and subsequent welding. When the sewage liner assembly 22 is removed from the sewage tank shell 21, the first connector portion 232 of the connector 23 is disconnected from the end of the sewage inlet pipe 212, and the connector 23 is connected to the sewage discharge chamber 221. When the sewage liner assembly 22 is installed on the sewage tank shell 21, the first connector portion 232 of the connector 23 is connected to the end of the sewage inlet pipe 212.

[0139] When the connector 23 is positioned between the end of the inlet pipe 212 and the wastewater discharge chamber 221, the inlet pipe 212, connector 23, wastewater discharge chamber 221, wastewater chamber 211, and return air section 222 are sequentially connected. Water vapor is drawn into the connector 23 and wastewater discharge chamber 221 from the inlet pipe 212, with wastewater in the water vapor falling into the wastewater chamber 211; the airflow in the water vapor flows from the wastewater chamber 211 and exits into the return air section 222. When the wastewater in the wastewater chamber 211 accumulates to a certain volume, the wastewater tank 20 is removed from the floor scrubber to empty the wastewater.

[0140] By installing the aforementioned connector 23 between the end of the inlet pipe 212 and the waste collection chamber 221, the airflow in the water vapor passes through the inlet pipe 212 and connector 231, flows downwards towards the waste collection chamber 221, and then flows upwards from the front of the waste collection chamber 221 towards the return air section 222, forming a complete airflow direction. The connector 23 optimizes the airflow direction during air reversal, avoids abrupt airflow turns, improves the smoothness of airflow, thereby reducing noise and enhancing the user experience.

[0141] Please see Figure 36 , Figure 36 This is a structural schematic diagram of the connector in the first embodiment of the sewage tank of this application. (Combined with...) Figures 33 to 35 In some embodiments, the first connector 232 and the end of the sewage inlet pipe 212 are sealed together, ensuring both the connection between the first connector 232 and the end of the sewage inlet pipe 212 and the airtightness between them. The sealing method can be, but is not limited to, welding and sealing rings.

[0142] In one specific embodiment, one of the first connector portion 232 and the end of the sewage inlet pipe 212 is provided with a connector insertion portion 2321. The other of the first connector portion 232 and the end of the sewage inlet pipe 212 is provided with a connector insertion groove (not shown in the figure). The connector insertion portion 2321 is inserted into and sealed in the connector insertion groove, thereby achieving a sealed connection between the first connector portion 232 and the end of the sewage inlet pipe 212, and thus improving the sealing performance between the first connector portion 232 and the sewage inlet pipe 212.

[0143] In this embodiment, the first connector portion 232 is provided with a connector insertion portion 2321. The connector insertion portion 2321 is welded to or integrally formed on the first connector portion 232. A connector insertion groove is provided at the end of the sewage inlet pipe 212. The connector insertion portion 2321 of the first connector portion 232 is inserted into the connector insertion groove at the end of the sewage inlet pipe 212, and then the connector insertion portion 2321 is welded into the connector insertion groove, etc. This arrangement improves the convenience of sealing the connector 23 to the end of the sewage inlet pipe 212.

[0144] In other embodiments, a connector insertion groove is provided at the end of the first connector portion 232. A connector insertion portion 2321 is provided at the end of the sewage inlet pipe 212. The connector insertion portion 2321 is welded or integrally formed to the end of the sewage inlet pipe 212. The connector insertion portion 2321 at the end of the sewage inlet pipe 212 is inserted into the connector insertion groove of the first connector portion 232, and then the connector insertion portion 2321 is welded into the connector insertion groove, etc.

[0145] In another specific embodiment, one of the outer periphery of the first connector portion 232 and the outer periphery of the end of the sewage inlet pipe 212 is provided with a connector snap-fit ​​portion (not shown in the figure). One of the outer periphery of the first connector portion 232 and the outer periphery of the end of the sewage inlet pipe 212 is provided with a connector snap-fit ​​groove 2332. The connector snap-fit ​​portion snaps into and seals within the connector snap-fit ​​groove 2332, thereby achieving a sealed connection between the first connector portion 232 and the end of the sewage inlet pipe 212, and thus improving the sealing performance between the first connector portion 232 and the sewage inlet pipe 212.

[0146] In one embodiment, a connector snap-fit ​​portion is provided on the outer periphery of the first connector portion 232. The connector snap-fit ​​portion is integrally formed or welded to the outer periphery of the first connector portion 232. A connector snap-fit ​​groove 2332 is provided on the outer periphery of the end of the sewage inlet pipe 212. When the connector snap-fit ​​portion of the first connector portion 232 snaps into the connector snap-fit ​​groove 2332 on the outer periphery of the sewage inlet pipe 212, it can tighten the connector sealing ring (not shown in the figure) on the outer periphery of the sewage inlet pipe 212, achieving a sealed connection between the first connector portion 232 and the end of the sewage inlet pipe 212, thereby improving the convenience of sealing the connector 23 to the end of the sewage inlet pipe 212.

[0147] In another embodiment, a connector locking groove 2332 is provided on the outer periphery of the first connector portion 232. A connector locking portion is provided on the outer periphery of the end of the sewage inlet pipe 212. The connector locking portion is integrally formed or welded to the outer periphery of the end of the sewage inlet pipe 212. When the connector locking portion at the end of the sewage inlet pipe 212 engages with the connector locking groove 2332 on the outer periphery of the first connector portion 232, it can tighten the connector sealing ring on the outer periphery of the first connector portion 232, thereby achieving a sealed connection between the first connector portion 232 and the end of the sewage inlet pipe 212.

[0148] In some embodiments, the second connector 233 and the waste collection chamber 221 are press-fitted together, ensuring a detachable connection between the second connector 233 and the waste collection chamber 221 while also maintaining a tight seal between them. The sealing connection method described above can be, but is not limited to, using a connector sealing ring, etc.

[0149] In one specific embodiment, a first connector sealing part 2331 is provided on the side of the waste collection chamber 221 or the second connector portion 233. The second connector portion 233 is press-fitted against the side of the waste collection chamber 221 through the first connector sealing part 2331. The first connector sealing part 2331 can be provided in two positions. The first connector sealing part 2331 can be a sealing rubber structure, such as a connector sealing ring.

[0150] When the first connector sealing part 2331 is provided on the side of the sewage discharge chamber 221, the first connector sealing part 2331 can be detached or fixed to the side of the sewage discharge chamber 221. The first connector sealing part 2331 on the side of the sewage discharge chamber 221 seals against the second connector part 233, achieving a sealed abutment between the second connector part 233 of the connector 23 and the side of the sewage discharge chamber 221. When the second connector part 233 is provided with the first connector sealing part 2331, the first connector sealing part 2331 can be detached or fixed to the end of the second connector part 233. The side of the sewage discharge chamber 221 seals against the first connector sealing part 2331, achieving a sealed abutment between the first connector sealing part 2331 of the connector 23 and the sewage discharge chamber 221.

[0151] In some embodiments, a mating surface (not shown in the figure) may be formed at the connection position between the second connector portion 233 and the side of the sewage discharge chamber 221. The mating surface faces the end of the sewage inlet pipe 212 and is inclined downward. By defining the above-mentioned mating surface, when the sewage liner assembly 22 is installed downward on the sewage tank shell 21, a certain component force of the sewage discharge chamber 221 can act on the second connector portion 233 of the connector 23, thereby improving the sealing performance between the second connector portion 233 of the connector 23 and the sewage discharge chamber 221.

[0152] Please see Figure 37 , Figure 37This is a partial cross-sectional schematic diagram of the first embodiment of the sewage tank of this application. Combined with... Figures 33 to 36 In some embodiments, a sewage handle 2112 is provided on the outer side of one end of the sewage tank shell 21. The sewage handle 2112 is convenient for the user to grasp with their fingers or hands. The specific structure of the sewage handle 2112 is not limited. The sewage inlet pipe 212 is located on the inner side of the other end of the sewage tank shell 21. That is, the sewage inlet pipe 212 is distributed on the side of the sewage tank shell 21 opposite to where the sewage handle 2112 is located. The sewage inlet pipe 212 and the sewage handle 2112 are arranged opposite to each other. When the sewage in the sewage tank 20 reaches a certain volume, the user acts on the sewage handle 2112, that is, the sewage tank shell 21 tilts under the action of the sewage handle 2112, and the sewage in the sewage cavity 211 is discharged through the sewage installation port 2111 on the side close to the sewage inlet pipe 212.

[0153] Because the height of the second connector portion 233 of the connector 23 is higher than the water level line when the sewage chamber 211 is poured at its maximum capacity, the sewage can avoid the second connector portion 233 when the sewage in the sewage tank 20 is poured. This reduces the risk of sewage from the sewage tank 20 entering the sewage inlet pipe 212 through the second connector portion 233 and causing sewage to backflow from the bottom of the sewage inlet pipe 212, thereby improving the user experience. By raising the height of the end of the sewage inlet pipe 212 through the second connector portion 233, the risk of sewage backflow when the sewage tank 20 is poured is effectively avoided, greatly improving the user experience.

[0154] Please see Figure 38 , Figure 39 as well as Figure 40 , Figure 38 This is a cross-sectional schematic diagram of the sewage tank shell and the sewage inlet pipe in the first embodiment of the sewage tank of this application; Figure 39 This is a cross-sectional schematic diagram of the second embodiment of the sewage tank in this application; Figure 40 yes Figure 39 The diagram shows the structure of O. (Combined with...) Figures 33 to 37 In some embodiments, the first connector 232 and the end of the sewage inlet pipe 212 are press-fitted together. While ensuring a detachable connection between the first connector 232 and the end of the sewage inlet pipe 212, it is also necessary to ensure a tight seal between them to reduce water and air leakage. The aforementioned sealing connection method can be, but is not limited to, using a connector sealing ring 2333, etc.

[0155] In one specific embodiment, a second connector sealing part 2322 is provided at the end of the sewage inlet pipe 212 or the first connector portion 232. The first connector portion 232 is press-fitted against the end of the sewage inlet pipe 212 through the second connector sealing part 2322. The second connector sealing part 2322 can be provided in two positions. The second connector sealing part 2322 can be a sealing rubber-coated structure, such as a connector sealing ring 2333.

[0156] When the end of the sewage inlet pipe 212 is provided with a second joint sealing part 2322, the second joint sealing part 2322 can be detached or fixed to the end of the sewage inlet pipe 212. The second joint sealing part 2322 on the end of the sewage inlet pipe 212 seals against the first joint part 232, realizing a sealed abutment between the first joint part 232 of the connector 23 and the end of the sewage inlet pipe 212. When the first joint part 232 is provided with a second joint sealing part 2322, the second joint sealing part 2322 can be detached or fixed to the end of the first joint part 232. The end of the sewage inlet pipe 212 is sealed and pressed against the second joint sealing part 2322.

[0157] In some embodiments, the second connector 233 and the waste collection chamber 221 are sealed together, ensuring both the connection and the seal between them. The sealing method can be, but is not limited to, welding and a connector sealing ring 2333.

[0158] Please see Figure 41 , Figure 41 This is a partial schematic diagram of the second embodiment of the wastewater tank of this application. (In conjunction with...) Figures 33 to 40 In one specific embodiment, one of the outer periphery of the second connector portion 233 and the outer periphery of the waste collection cavity 221 is provided with a connector snap-fit ​​portion. One of the outer periphery of the second connector portion 233 and the outer periphery of the waste collection cavity 221 is provided with a connector snap-fit ​​groove 2332. The connector snap-fit ​​portion snaps into and seals within the connector snap-fit ​​groove 2332, achieving a sealed connection between the second connector portion 233 and the waste collection cavity 221, thereby improving the sealing performance between the second connector portion 233 and the waste collection cavity 221.

[0159] In one embodiment, a connector snap-fit ​​portion is provided on the outer periphery of the second connector portion 233. The connector snap-fit ​​portion is integrally formed or welded to the outer periphery of the second connector portion 233. A connector snap-fit ​​groove 2332 is provided on the outer periphery of the waste collection cavity 221. When the connector snap-fit ​​portion of the second connector portion 233 snaps into the connector snap-fit ​​groove 2332 on the outer periphery of the waste collection cavity 221, it can tighten the connector sealing ring 2333 on the outer periphery of the waste collection cavity 221, achieving a sealed connection between the second connector portion 233 and the waste collection cavity 221, thereby improving the convenience of sealing the connector 23 to the waste collection cavity 221.

[0160] In this embodiment, a connector locking groove 2332 is provided on the outer periphery of the second connector portion 233. A connector locking portion is provided on the outer periphery of the waste collection cavity 221. The connector locking portion is integrally formed or welded to the outer periphery of the waste collection cavity 221. When the connector locking portion of the waste collection cavity 221 engages with the connector locking groove 2332 on the outer periphery of the second connector portion 233, it can lock the connector sealing ring 2333 on the outer periphery of the second connector portion 233, thereby achieving a sealed connection between the second connector portion 233 and the waste collection cavity 221.

[0161] In one specific embodiment, one of the second connector portion 233 and the waste collection chamber 221 is provided with a connector insertion portion 2321. The other of the second connector portion 233 and the waste collection chamber 221 is provided with a connector insertion groove. The connector insertion portion 2321 is inserted into and sealed in the connector insertion groove, thereby achieving a sealed connection between the second connector portion 233 and the waste collection chamber 221.

[0162] In one embodiment, the second connector portion 233 is provided with a connector insertion portion 2321. The waste collection chamber 221 is provided with a connector insertion groove. The connector insertion portion 2321 of the second connector portion 233 is inserted into the connector insertion groove of the waste collection chamber 221, and then the connector insertion portion 2321 is welded into the connector insertion groove, etc. In other embodiments, the end of the second connector portion 233 is provided with a connector insertion groove. The waste collection chamber 221 is provided with a connector insertion portion 2321. The connector insertion portion 2321 of the waste collection chamber 221 is inserted into the connector insertion groove of the second connector portion 233, and then the connector insertion portion 2321 is welded into the connector insertion groove, etc.

[0163] In some embodiments, the connector 23 is a bent pipe. The bent pipe is arc-shaped. That is, there is an arc transition between the sewage inlet pipe 212 and the sewage outlet chamber 221, which not only improves the smoothness of water and air flow, but also improves the stability of the pipe installed between the sewage inlet pipe 212 and the sewage outlet chamber 221.

[0164] The aforementioned sewage inlet pipe 212 is vertically arranged. That is, there is a vertical seal between the first joint 232 of the connector pipe 231 and the end of the sewage inlet pipe 212; and a horizontal seal between the second joint 233 of the connector pipe 231 and the side of the sewage discharge chamber 221, etc.

[0165] Please see Figure 42 , Figure 42 This is a structural schematic diagram of the connector in the second embodiment of the sewage tank of this application. (Combined with...) Figures 33 to 41In some embodiments, the wastewater tank 20 includes a wastewater negative pressure assembly 24. The wastewater negative pressure assembly 24 is disposed on the top of the wastewater tank housing 21. The wastewater negative pressure assembly 24 communicates with the return air section 222. The wastewater negative pressure assembly 24 provides suction force so that water vapor sequentially enters the wastewater chamber 211 from the inlet pipe 212, connector 23, and wastewater discharge chamber 221, and then the airflow in the wastewater chamber 211 is drawn from the return air section 222 to the wastewater negative pressure assembly 24. The aforementioned wastewater negative pressure assembly 24 may be, but is not limited to, a vacuum fan, used to draw airflow from inside the wastewater tank 20, etc.

[0166] Please see Figure 43 , Figure 44 as well as Figure 45 , Figure 43 This is a schematic diagram of the structure of an embodiment of the brush component of this application; Figure 44 This is a first cross-sectional schematic diagram of an embodiment of the brush component of this application; Figure 45 yes Figure 44 The diagram shows the structure of P. The floor brush assembly 10 is used to clean the floor (not shown in the diagram), removing dust, stains, and moisture. The floor brush assembly 10 includes a floor brush body 11, a water tank 12, a cleaning fluid tank 13, and a roller brush assembly 14. The floor brush body 11 provides mounting positions for the water tank 12, the cleaning fluid tank 13, and the roller brush assembly 14. The water tank 12 is used to store clean water. The water tank 12 is located on the floor brush body 11. The water tank 12 can be detached from or fixed to the floor brush body 11. The cleaning fluid tank 13 is used to store cleaning fluid. The cleaning fluid tank 13 is located on the floor brush body 11. The cleaning fluid tank 13 can be detached from or fixed to the floor brush body 11. The roller brush assembly 14 contacts the floor by rotating, effectively cleaning the floor. The roller brush assembly 14 is located on the floor brush body 11. The roller brush assembly 14 can be detached from the floor brush body 11.

[0167] The floor brush assembly 10 also includes a mixing and cleaning assembly 15. The mixing and cleaning assembly 15 includes a mixing tank 151, a water inlet 152, a liquid inlet 153, and a liquid outlet 154. The water inlet 152, liquid inlet 153, and liquid outlet 154 are all connected to the mixing tank 151. The water inlet 152 is for clean water to enter. The liquid inlet 153 is for cleaning fluid to enter. The liquid outlet 154 is for the mixed fluid to flow out. The water inlet 152 is in a closable connection to the clean water tank 12. Alternatively, the water inlet 152 may be disconnected from the clean water tank 12. The liquid inlet 153 is in a closable connection to the cleaning fluid tank 13. Alternatively, the liquid inlet 153 may be disconnected from the cleaning fluid tank 13. The liquid outlet 154 is connected to the roller brush so that the mixed fluid flows onto the roller brush assembly 14.

[0168] By connecting the water inlet 152 to the clean water tank 12 and the liquid inlet 153 to the cleaning liquid tank 13, clean water from the clean water tank 12 flows into the mixing tank 151 through the water inlet 152, and cleaning liquid from the cleaning liquid tank 13 flows into the mixing tank 151 through the liquid inlet 153. The clean water and cleaning liquid are then further mixed evenly inside the mixing tank 151. The resulting mixture is then connected to the roller brush assembly 14 through the liquid outlet 154. This method not only achieves automatic and even mixing of clean water and cleaning liquid, thus improving the floor cleaning effect, but also eliminates the need for manual operation, thereby enhancing the user experience.

[0169] The number of water inlet sections 152 may be, but is not limited to, one, two, or three or more. The number of liquid inlet sections 153 may be, but is not limited to, one, two, or three or more. The number of liquid outlet sections 154 may be, but is not limited to, one, two, or three or more. In this embodiment, the number of water inlet sections 152, the number of liquid inlet sections 153, and the number of liquid outlet sections 154 are all one.

[0170] Please see Figure 46 , Figure 47 as well as Figure 48 , Figure 46 This is a schematic diagram of the structure of the hybrid cleaning component in the floor brush assembly of this application; Figure 47 This is a schematic diagram of the structure of the mixing and cleaning component and the first valve body cavity in the floor brush assembly of this application; Figure 48 This is a cross-sectional schematic diagram of the mixing and cleaning component and the first valve body cavity in the floor brush assembly of this application. (Combined with...) Figures 43 to 45 The water inlet 152 and liquid outlet 154 can be located at any position in the mixing tank 151. In one specific embodiment, the water inlet 152 and liquid outlet 154 are located on opposite sides of the mixing tank 151. When the water inlet 152 is located on one side of the mixing tank 151, clean water enters the mixing tank 151 from that side. When the liquid outlet 154 is located on the other side of the mixing tank 151, cleaning liquid enters the mixing tank 151 from the other side. The clean water and cleaning liquid enter the mixing tank 151 from opposite sides, and there is a certain force between them, which makes the clean water and cleaning liquid mix more evenly, thereby further improving the cleaning effect.

[0171] In some embodiments, the mixing tank 151 forms a mixing cavity 1511. The mixing cavity 1511 is used to contain clean water and cleaning fluid. The mixing cavity 1511 provides a mixing space for the clean water and cleaning fluid. The mixing cavity 1511 can be, but is not limited to, a square cavity, a circular cavity, an elliptical cavity, or an irregularly shaped cavity. When the mixing cavity 1511 is a square cavity, the square cavity can be, but is not limited to, a square cavity or a rectangular cavity. When the mixing cavity 1511 is an irregularly shaped cavity, the irregularly shaped cavity can be, but is not limited to, a combination of a square cavity portion and an elliptical cavity portion.

[0172] In some embodiments, the water inlet 152 and the liquid outlet 154 are located on the same side of the mixing tank 151; and the liquid inlet 153 and the liquid outlet 154 face the roller brush assembly 14. The liquid inlet 153 is located on the other side of the mixing tank 151 and away from the roller brush assembly 14. By defining the positional relationship of the water inlet 152, the liquid outlet 154, and the liquid inlet 153 relative to the roller brush assembly 14, internal space of the floor brush assembly 10 can be saved, making the internal structure of the floor brush assembly 10 more compact.

[0173] In some embodiments, the mixing tank 151 is located at the bottom of the cleaning fluid tank 13, which can save internal space of the floor brush assembly 10, making the internal structure of the floor brush assembly 10 more compact.

[0174] In some embodiments, the floor brush assembly 10 includes a first valve body cavity 162. The first valve body cavity 162 is located at the bottom of the cleaning fluid tank 13. The first valve body cavity 162 is in openable and closable communication with the cleaning fluid tank 13. Specifically, when the first valve body cavity 162 is in communication with the cleaning fluid tank 13, cleaning fluid in the cleaning fluid tank 13 can enter the first valve body cavity 162. Alternatively, when the first valve body cavity 162 is disconnected from the cleaning fluid tank 13, cleaning fluid in the cleaning fluid tank 13 cannot enter the first valve body cavity 162. The top of the mixing tank 151 and the bottom of the first valve body cavity 162 share a common wall. Specifically, the top of the mixing tank 151 can utilize the bottom of the first valve body cavity 162; or, the bottom of the first valve body cavity 162 can utilize the top of the mixing tank 151. By having the top of the mixing tank 151 and the bottom of the first valve body cavity 162 share a common wall, not only is the number of parts reduced, thus reducing costs, but the structure is also compact, thereby reducing the overall size of the floor brush assembly 10.

[0175] Please see Figure 49 , Figure 50 as well as Figure 51 , Figure 49 This is a schematic diagram of the structure of the mixing and cleaning component, the first valve body cavity, and the first valve body in the floor brush assembly of this application; Figure 50 This is a first partial schematic diagram of an embodiment of the brush component of this application; Figure 51 yes Figure 50 The diagram shows the structure of Q. (Combined with...) Figures 43 to 48In some embodiments, the floor brush assembly 10 includes a first valve body 161, a first valve body cavity 162, and a first liquid extraction component 163. The first valve body 161 is openably and closably connected to the bottom of the cleaning fluid tank 13. When the cleaning fluid tank 13 is installed on the floor brush body 11, the first valve body 161 is connected to the bottom of the cleaning fluid tank 13, and at this time, the first valve body 161 is in the open state. When the cleaning fluid tank 13 is removed from the floor brush body 11, the first valve body 161 is closed at the bottom of the cleaning fluid tank 13, and at this time, the first valve body 161 is in the closed state. The first valve body 161 and the first valve body cavity 162 are openably and closably connected. Alternatively, the first valve body 161 and the first valve body cavity 162 may be disconnected. The first liquid extraction component 163 is openably and closably connected to both the first valve body cavity 162 and the mixing tank 151. The first liquid extraction component 163 is connected to the first valve body cavity 162; or, the first liquid extraction component 163 is disconnected from the first valve body cavity 162. The first liquid extraction component 163 is connected to the mixing tank 151; or, the first liquid extraction component 163 is disconnected from the mixing tank 151.

[0176] When the cleaning fluid tank 13 is installed on the floor brush body 11 and the first suction component 163 is working, the cleaning fluid in the cleaning fluid tank 13 passes through the first valve body 161 and the first valve body cavity 162 and is drawn into the first suction component 163, and then drawn out from the first suction component 163 into the mixing tank 151. The mixed fluid is then sprayed onto the roller brush assembly 14. The aforementioned first suction component 163 may be, but is not limited to, a first suction peristaltic pump, etc.

[0177] Through the combined action of the first valve body 161, the first valve body cavity 162, and the first liquid extraction component 163, the amount of cleaning fluid used can be controlled, avoiding excessive foaming in the wastewater tank (not shown in the figure) and a sticky feeling on the ground due to excessive cleaning fluid; and avoiding poor cleaning effect due to insufficient cleaning fluid. The structure and connection relationship between the first valve body 161 and the first valve body cavity 162 are conventionally known to those skilled in the art and will not be described in detail here.

[0178] Specifically, the first liquid extraction component 163 includes a first liquid extraction section 1631 and a second liquid extraction section 1632. The first valve body cavity 162 includes a valve body liquid extraction section 1621. The valve body liquid extraction section 1621 is connected to the first liquid extraction section 1631. The second liquid extraction section 1632 is connected to the inlet section 153. When the first liquid extraction component 163 is operating, the cleaning liquid in the cleaning liquid tank 13 enters the first liquid extraction section 1631 of the first liquid extraction component 163 through the valve body liquid extraction section 1621 of the first valve body cavity 162, and then enters the inlet section 153 from the second liquid extraction section 1632 of the first liquid extraction component 163, thereby entering the mixing tank 151 through the inlet section 153.

[0179] Please see Figure 52 and Figure 53 , Figure 52 This is a second cross-sectional schematic diagram of an embodiment of the brush component of this application; Figure 53 yes Figure 52 The diagram shows the structure of R. (Combined with...) Figures 43 to 51 In some embodiments, the floor brush assembly 10 includes a second valve body 171, a second valve body cavity 172, and a second liquid extraction component 173. The second valve body 171 is openably and closably connected to the bottom of the clean water tank 12. When the clean water tank 12 is installed on the floor brush body 11, the second valve body 171 is connected to the bottom of the clean water tank 12, and at this time, the second valve body 171 is in the open state. When the clean water tank 12 is removed from the floor brush body 11, the second valve body 171 is closed at the bottom of the clean water tank 12, and at this time, the second valve body 171 is in the closed state. The second valve body 171 and the second valve body cavity 172 are openably and closably connected. Alternatively, the second valve body 171 and the second valve body cavity 172 may be disconnected. The second liquid extraction component 173 is openably and closably connected to both the second valve body cavity 172 and the mixing tank 151. The second liquid extraction component 173 is connected to the second valve body cavity 172; or, the second liquid extraction component 173 is disconnected from the second valve body cavity 172. The second liquid extraction component 173 is connected to the mixing tank 151; or, the second liquid extraction component 173 is disconnected from the mixing tank 151.

[0180] When the clean water tank 12 is installed on the brush body 11 and the second pumping component 173 is working, the clean water in the clean water tank 12 passes through the second valve body 171 and the second valve body cavity 172 and is drawn into the second pumping component 173, and then drawn out from the second pumping component 173 into the mixing tank 151. The mixed liquid is then sprayed onto the roller brush assembly 14. The aforementioned second pumping component 173 can be, but is not limited to, a second pumping peristaltic pump. Through the combined action of the second valve body 171, the second valve body cavity, and the second pumping component 173, the amount of clean water used can be controlled, and clean water flow can be achieved.

[0181] Please see Figure 55 as well as Figure 56 , Figure 54 This is an exploded view of an embodiment of the brush component of this application; Figure 55 This is a second partial schematic diagram of an embodiment of the brush component of this application; Figure 56 This is a third partial schematic diagram of an embodiment of the brush component of this application. (In conjunction with...) Figures 43 to 53 The aforementioned clean water tank 12 and cleaning fluid tank 13 can be installed separately. When the clean water tank 12 and cleaning fluid tank 13 are installed separately, the clean water tank 12 can be detachably connected to the floor brush body 11, and the cleaning fluid tank 13 can be detached from the floor brush body 11, wherein the clean water tank 12 and the cleaning fluid tank 13 can be removed independently.

[0182] The aforementioned water tank 12 and cleaning fluid tank 13 can be integrated. When the water tank 12 and cleaning fluid tank 13 are integrated, the floor brush body 11 includes a floor brush cover 111 and a floor brush housing 112. The floor brush housing 112 has a water tank 1121 and a cleaning fluid tank 1122. The floor brush cover 111 covers the water tank 1121 and the cleaning fluid tank 1122 of the floor brush housing 112. The floor brush cover 111 is detachable from the floor brush housing 112. The detachment method can be, but is not limited to, snap-fit, plug-in, and bolts. When the floor brush cover 111 covers the water tank 1121 and the cleaning fluid tank 1122 of the floor brush housing 112, the aforementioned water tank 12 is formed between the floor brush cover 111 and the water tank 1121 of the floor brush housing 112; the aforementioned cleaning fluid tank 13 is formed between the floor brush cover 111 and the cleaning fluid tank 1122 of the floor brush housing 112.

[0183] By connecting the aforementioned floor brush cover 111 and floor brush housing 112, the clean water tank 12 and cleaning fluid tank 13 are integrated, which can reduce costs. The aforementioned clean water tank 1121 and cleaning fluid tank 1122 are arranged on the same wall. The clean water tank 1121 is located at the front end of the floor brush assembly 10, while the cleaning fluid tank 1122 is located at the rear side of the floor brush assembly 10.

[0184] In some embodiments, the floor brush assembly 10 further includes a cleaning fluid float assembly 164. The cleaning fluid float assembly 164 is disposed in the cleaning fluid tank 13. The cleaning fluid float assembly 164 is used to detect the volume of cleaning fluid in the cleaning fluid tank 13. When the cleaning fluid float assembly 164 floats to the lowest point of the cleaning fluid tank 13, it communicates with a detection component (not shown in the figure) to remind the user to add cleaning fluid, etc. The cleaning fluid float assembly 164 includes at least a float with a cavity, which can float on the surface of the cleaning fluid, etc.

[0185] In some embodiments, the floor brush assembly 10 further includes a water distributor (not shown in the figure). The water distributor is connected to the liquid outlet 154 in the mixing tank 151 and the roller brush assembly 14, respectively. The mixture in the liquid outlet 154 is sprayed onto the roller brush assembly 14 through the water distributor to achieve uniformity of the mixture sprayed onto the roller brush assembly 14.

[0186] Please see Figure 57 , Figure 58 , Figure 59 as well as Figure 60 , Figure 57 This is a third cross-sectional schematic diagram of an embodiment of the brush component of this application; Figure 58 yes Figure 57 The diagram shows the structure of S. Figure 59 This is a first structural schematic diagram of an embodiment of the brush component of this application; Figure 60This is a second structural schematic diagram of an embodiment of the floor brush assembly of this application. In some embodiments, the floor brush assembly 10 further includes a first connector assembly 181 and a second connector assembly 182. The first connector assembly 181 is rotatably connected to the floor brush body 11 in the front-to-back direction, so that the first connector assembly 181 can rotate at any angle relative to the floor brush body 11, such as upright or lying down. The second connector assembly 182 is rotatably connected to the first connector assembly 181 in the left-to-right direction, so that the second connector assembly 182 can swing left and right relative to the first connector assembly 181. The lower part of the floor scrubber body 30 is connected to the second connector assembly 182. The floor scrubber body 30 and the second connector assembly 182 are detachably connected, meaning the floor scrubber body 30 can swing left and right with the second connector assembly 182.

[0187] Through the combined action of the aforementioned floor brush body 11, first connector assembly 181, second connector assembly 182, and floor scrubber body 30, the floor scrubber body 30 can not only rotate back and forth, making it convenient for users to use it upright or at a low angle when lying down, but also swing left and right, making it convenient for users to clean a larger area with ease and effort. This makes the entire floor scrubber 100 structure more flexible and easier to control.

[0188] Please see Figure 61 as well as Figure 62 , Figure 61 This is an exploded view of the first connector assembly and the second connector assembly in one embodiment of the brush assembly of this application; Figure 62 This is a fourth cross-sectional schematic diagram of an embodiment of the brush component of this application. (In conjunction with...) Figures 57 to 60 In some embodiments, a connector shaft 183 is provided between the first connector assembly 181 and the second connector assembly 182, which not only allows the second connector assembly 182 to swing left and right relative to the first connector assembly 181 through the connector shaft 183, but also has a simple structure and is easy to operate, while being more flexible and controllable.

[0189] Specifically, the connector shaft 183 extends in the front-to-back direction and is inclined downwards. When the floor scrubber body 30 swings in the left-to-right direction, at least a portion of the force can be applied to the floor brush assembly 10, improving the stability of the floor brush assembly 10 in cleaning the floor.

[0190] Furthermore, the angle between the forward and backward extension direction of the connector shaft 183 and the horizontal plane is greater than or equal to 15 degrees and less than or equal to 25 degrees. This angle limitation not only ensures the left-right swing of the floor scrubber body 30 but also improves the stability of the floor brush assembly 10. The angle between the forward and backward extension direction of the connector shaft 183 and the horizontal plane is defined as α. α can be, but is not limited to, 15 degrees, 17 degrees, 18.5 degrees, 19 degrees, 21 degrees, 22.5 degrees, 23 degrees, 24 degrees, and 25 degrees.

[0191] In some embodiments, review Figure 1 The floor scrubber 100 also includes a battery pack assembly 50. The battery pack assembly 50 is detachably attached to the upper part of the floor scrubber body 30. The battery pack assembly 50 can be connected to the upper part of the floor scrubber body 30 by snap-fit ​​or plug-in methods. The battery pack assembly 50 is used to provide power for the floor scrubber 100 to operate normally.
