[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Please refer to the attached Figures 1-8As shown, an embodiment of the present invention provides a sewage tank with dry-wet separation and sewage detection, which is used to collect sewage when the floor scrubber is working. The sewage tank includes a sewage bucket 1, a tank cover 3, a sewage suction pipe 2, a dry-wet separator 5 and a sewage detection column 4. The tank cover 3 is detachably covered on the upper end of the sewage bucket 1. The dry-wet separator 5 and the sewage detection column 4 are respectively connected to the lower end of the tank cover 3 and extend into the sewage bucket 1. The dry-wet separator 5 and the sewage detection column 4 are spaced apart. The side of the dry-wet separator 5 facing away from the sewage detection column 4 is provided with an opening 54 connected to the inner cavity of the dry-wet separator 5, and the opening 54 fits the The inner wall of the sewage bucket 1 forms a closed cavity 7, the bottom end of the dry-wet separator 5 is provided with a mounting hole 11 and a plurality of filter holes 12 staggered from the mounting hole 11, and the side wall of the dry-wet separator 5 facing the sewage detection column 4 is provided with a plurality of air vents 13 near its bottom end. The sewage suction pipe 2 extends from the bottom of the sewage bucket 1 through the mounting hole 11 into the closed cavity 7, and the upper end of the sewage suction pipe 2 is higher than the air vent 13. The box cover 3 is provided with an air intake 6 connected to the sewage bucket 1.

[0031] During operation, the suction port of the suction motor installed on the floor scrubber is connected to the air inlet 6 of the sewage bucket 1 to generate suction force in the sewage bucket 1, thereby forming an air flow from the sewage suction pipe 2 to the inner cavity of the dry-wet separator 5, then into the sewage bucket 1, and finally out of the air inlet 6. Under the action of the airflow suction, the sewage (mixed with solid waste) sucked up by the sewage suction pipe 2 flows out from the upper end opening of the sewage suction pipe 2 and falls into the inner cavity of the dry-wet separator 5. After being filtered in the dry-wet separator 5, the sewage falls into the sewage bucket 1, and the solid waste remains in the dry-wet separator 5. The above process is carried out simultaneously when the floor scrubber is operated to clean the floor.

[0032] The sewage tank is mounted on the main body of the floor scrubber. When the user operates the floor scrubber to clean, the floor scrubber is positioned at a certain angle. Therefore, the wet-dry separator 5 and the sewage detection column 4 of the sewage tank of the present invention are separated and placed in the sewage bucket 1 to form opposite front and rear sides, with the sewage detection column 4 located at the front and the wet-dry separator 5 located at the rear. When the floor scrubber is tilted, the sewage tank tilts along with it. At this time, the sewage detection column 4 in the sewage bucket 1 is located above the tilted wet-dry separator 5. The separation and tilting of the wet-dry separator 5 and the sewage detection column 4 prevent water on the wet-dry separator 5 from flowing to the sewage detection column 4. This solves the technical problem in the prior art where a water curtain is easily formed between the sewage detection devices when sewage flows from the wet-dry separator 5 to the sewage tank, causing false alarms.

[0033] Furthermore, the sewage detection column 4 is separated from the wet-dry separator 5, and the installation and disassembly of the wet-dry separator 5 no longer affects the sewage detection column 4, which can avoid collision and damage to the sewage detection column 4 and improve the service life of the sewage detection column 4.

[0034] More importantly, the present invention fits the open opening 54 of the inner cavity of the dry-wet separator 5 to the inner wall of the sewage bucket 1 to form a closed cavity 7, the filter hole 12 and the vent 13 are both located at the bottom of the dry-wet separator 5, and the upper end of the sewage suction pipe 2 is higher than the filter hole 12 and the vent 13. The closed cavity 7 allows gas or liquid to flow out only from the filter hole 12 and the vent 13 set at the bottom of the dry-wet separator 5. When the amount of sewage is small or there is little solid waste in the sewage, the sewage flowing into the dry-wet separator 5 can be almost immediately filtered and flow into the sewage bucket 1. At this time, there is no absolute distinction between the vent 13 and the filter hole 12, that is, the filter hole 12 can also be used for gas to pass through; when the amount of sewage is large and there is little solid waste in the sewage, the sewage flowing into the dry-wet separator 5 can be almost immediately filtered and flow into the sewage bucket 1. When there is a lot of solid debris in the sewage, the sewage flowing into the dry-wet separator 5 cannot be immediately filtered and flow into the sewage bucket 1. Instead, liquid will accumulate in the sewage bucket 1 and even clog the filter holes 12. At this time, some sewage can flow out from the vent 13 to prevent further blockage. When there is too much solid debris and even clogs the vent 13, the amount of sewage in the dry-wet separator 5 increases with the blockage and even overflows the vent 13. At this time, due to the continuous suction of the suction motor, the air pressure in the sewage bucket 1 drops, resulting in a continuously increasing pressure difference between the sewage bucket 1 and the inner cavity of the dry-wet separator 5. The blockage can be automatically cleared by utilizing the air pressure principle. Therefore, the above-mentioned arrangement of the present invention can avoid the complete blockage of the dry-wet separator 5. As can be seen from the above, the filter holes 12 and the vent 13 of the present invention can automatically realize mutual conversion and use according to the situation, thereby improving the filtering effect of the dry-wet separator 5.

[0035] The wet-dry separator 5 includes an upper main body 51 and a lower filter 52. The upper main body 51 and the lower filter 52 are detachably connected via a detachable connection structure. The mounting hole 11, the filter hole 12, and the vent 13 are all located in the lower filter 52. In a specific embodiment, the detachable connection structure includes a snap seat 15 provided on the lower filter 52 and a corresponding snap opening 14 provided on the upper main body 51. The snap seat 15 is adapted to snap into engagement with the snap opening 14. In this embodiment, three snap seats 15 are provided. The middle snap seat 15 is provided on the inner side of the lower filter 52, with one side of its outer side facing the corresponding snap opening 14. The two side snap seats 15 are provided on the outer side of the lower filter 52, with one side of its inner side facing the corresponding snap opening 14. By providing two sets of snap seats 15 facing opposite directions, the lower filter 52 is more stable after installation, preventing loosening or shaking. It is understandable that, in other embodiments, the detachable connection structure may also adopt commonly used detachable structures such as screw connection, plug connection, magnetic attraction, etc.

[0036] The side wall of the dry-wet separator 5 on the side facing the sewage detection column 4 is provided with an outwardly convex arc-shaped convex wall 53. In a specific embodiment, the dry-wet separator 5 is provided with a closed portion on the front side and the above-mentioned opening 54 on the rear side, and the sewage detection column 4 is located on one side of the front side of the dry-wet separator 5, and the arc-shaped convex wall 53 is the outer wall of the closed portion. The sewage detection column 4 is arranged on the other side of the opening 54 of the dry-wet separator 5, so that even if sewage overflows from the opening 54 of the dry-wet separator 5, it will not flow onto the sewage detection column 4, preventing false alarms caused by sewage overflowing onto the sewage detection column 4. The arc-shaped convex wall 53 on the closed portion of the front side of the dry-wet separator 5 can maximize the separation distance between the dry-wet separator 5 and the sewage detection column 4 in a limited space.

[0037] The air vent 13 is provided in the form of a slot-shaped opening, the lower end of which extends to the bottom end of the dry-wet separator 5, and the upper end of which extends above the bottom of the dry-wet separator 5.

[0038] The arc-shaped convex wall 53 of the dry-wet separator 5 is provided with a water baffle 8 on each side near the opening 54. The water baffle 8 is used to block the water flowing out of the opening 54 from splashing onto the sewage detection column 4. Optionally, the sewage detection column 4 and the dry-wet separator 5 are provided with a connecting plate 9 in the upper region of the separation region, and the connecting plate 9 connects the sewage detection column 4 and the dry-wet separator 5, respectively. The connecting plate 9 connects the sewage detection column 4 and the dry-wet separator 5 at the upper position, which is used to make the connection of the sewage detection column 4 more stable, while not blocking the separation gap between the sewage detection column 4 and the dry-wet separator 5 in the lower region, achieving the advantages of both leaving a gap and being firmly fixed.

[0039] The sewage detection column 4 is provided with two oppositely arranged sewage detection columns 4, and the lower end of the sewage detection column 4 is provided with a detection opening 43, and the detection opening 43 is arranged on one side of the two oppositely arranged sewage detection columns 4 or on the opposite side, or the detection opening 43 is arranged at the bottom end of the sewage detection column 4.

[0040] The sewage detection column 4 comprises a column body 41 and a detection piece 42, the column body 41 is provided with a sleeve hole, the sleeve hole corresponds to a through hole provided on the box cover 3, the detection piece 42 is arranged in the through hole and the sleeve hole from the upper end of the box cover 3, and the lower end of the detection piece 42 extends out of the sleeve hole.

[0041] An embodiment of the present invention further provides an integrated tank cover 3, comprising a tank cover 3 body, a wet-dry separator 5, and a sewage detection column 4. The tank cover 3 body, wet-dry separator 5, and sewage detection column 4 are integrated into one body. This integrated design of the tank cover 3 body, sewage detection column 4, and wet-dry separator 5 simplifies the structure and reduces the assembly process. The integrated tank cover 3 can be applied to the sewage tank described in this embodiment, thereby simplifying the sewage tank structure and reducing the assembly process.
