To the above problem the utility model discloses an in each implementation, through set up between dirty mouthful 111 and filtration pore (towards bung hole one side) and keep off wall 410 for the filth that gets into the sewage case from dirty mouthful 111 can be kept apart by keeping off wall 410, prevents that the solid particle who is bigger than the filtration pore in the filth from piling up on the filter plate, thereby promotes solid-liquid separation's effect.

Further, the blocking wall 410 is disposed on the barrel cover 200 and extends toward the bottom of the barrel to approach the filter plate 310. It can be understood that, as shown in fig. 8, the blocking wall 410 may also be disposed on the filter plate 310 and extend upward and toward the barrel cover 200, as shown in fig. 10, the blocking wall 410 extending upward and at least toward the barrel cover 200 is disposed on the filter plate 310, and the filter hole and the avoiding hole 311 are respectively located at two sides of the blocking wall 410 to prevent impurities from accumulating on the filter plate 310 during dirt intake. Thus, the same effects can be achieved, and the details are not described here.

The blocking wall 410 may abut against the filter plate 310 or the lid 200. Therefore, when the filter plate is not installed in place, the filter plate can be propped against the cover when the cover is installed at last, and the cover can be installed in place.

Further, a sewage inlet pipe 110 is arranged in the sewage bucket 100, the sewage inlet pipe 110 extends from the bottom wall of the sewage bucket 100 to the bucket opening direction, the sewage inlet 111 is arranged at the top end of the sewage inlet pipe 110, and a gap is formed between the sewage inlet pipe 110 and the wall of the sewage bucket 100.

Further, the shape of the escape opening 311 is adapted to the shape of the opening of the sewage inlet pipe 110. For example, if the pipe orifice of the sewage inlet pipe 110 is a circle with a radius r, the radius corresponding to the arc at the position of the avoidance opening 311 should be equal to or greater than r, so as not to hinder sewage inlet.

Meanwhile, due to the avoidance port 311, impurities in the air flow cannot be accumulated on the filter plate 310 due to the air flow, and the filter plate 310 does not have a cleaning dead angle at the avoidance port 311.

When the air flow comes out from the sewage inlet pipe 110, impurities in the air flow may fall to the side of the filter plate 310 facing the bung, and when the sewage is poured, the impurities attached to the side of the filter plate 310 facing the bung may enter the sewer along with the sewage, which may easily cause blockage of the sewer.

Therefore, the cover 200 is provided with a blocking wall 410 extending towards the bottom of the barrel and at least approaching the filter plate 310, and the filtering hole and the avoiding opening 311 are respectively positioned at two sides of the blocking wall 410 to prevent impurities from accumulating on the filter plate 310 during dirt intake.

Through envelope portion 420, avoid the impurity in the air current to directly get into the filter assembly, prolonged the life of filter assembly.

After the sewage is poured, the filter plate 310 needs to be removed for washing, and in order to prevent hands from being contaminated when the filter plate 310 is removed, a pair of hand-lifting portions 312 which are convenient to detach by hands are arranged on one side of the filter plate 310 facing the opening of the sewage bucket 100, and the two hand-lifting portions are arranged at intervals. The two handle parts are respectively provided with turnover edges, the turnover directions are opposite, and the turnover edges are provided with cambered surfaces with slightly concave middles, so that fingers can be conveniently placed in the turnover edges.

Further, the filtering holes are formed between the two handle parts 312, so that when sewage is poured, the sewage can be discharged from the filtering holes between the two handle parts, the discharge path of the sewage can avoid the flanging edges of the handle parts 312, the flanging edges are prevented from being polluted, and the cleanness of the flanging edges is kept.

Example 2:

as shown in fig. 9 and 10, a sewage inlet pipe 110 is disposed in the sewage bucket 100, the sewage inlet pipe 110 extends from the bottom wall of the sewage bucket 100 to the direction of the bung, and a gap is formed between the sewage inlet pipe 110 and the wall of the sewage bucket 100. The filter plate is detachably installed in the gap to avoid the sewage entering from the sewage inlet pipe 110. The filter plate 310 has a filter hole, and the filter plate 310 is provided with a connecting bracket 320 at a side facing the bottom of the tub for connecting the sewage inlet pipe 110.

In this embodiment, the sidewall of the slop pail 100 has a first plane, and when the slop pail 100 is assembled with the cleaning device, the sidewall of the slop pail 100 with the first plane is embedded into and attached to the cleaning device. The filter plate 310 is located in a gap between the sewage inlet pipe 110 and the first plane, a side of the filter plate 310 opposite to the first plane is a straight side, the straight side is parallel to the first plane, and the gap between the straight side and the first plane is completely filled by other parts of the filter plate 310.

Therefore, when the slop pail 100 is tilted towards the first plane at an angle perpendicular to the first plane, the included angle between the liquid level in the slop pail 100 and the first plane gradually increases from perpendicular to the first plane until the waste water is drained. In this process, the straight side of the filter plate 310 is always above the liquid level to ensure interception of impurities floating on the liquid level.

In this embodiment, the opening of the dirt intake pipe 110 is rectangular. The connecting bracket 320 on the filter plate 310 is a side plate, one end of the side plate is connected with the linear side of the filter plate 310 and is perpendicular to the linear side, the other end of the side plate extends to the bottom of the barrel and is attached to one side wall of the sewage inlet pipeline 110, and a pair of protrusions are respectively arranged on two sides of the side plate to clamp and fix the sewage inlet pipeline 110.

Example 3:

as shown in fig. 11, this embodiment shows another embodiment of the connecting bracket 320, and compared to the connecting bracket 320 in example 1, the connecting bracket 320 in this embodiment is provided with a vent 323 between the nozzle of the sewage inlet pipe 110 and the avoiding opening 311. In this way, a portion of the air flow coming out through the dirt intake pipe 110 can be diffused into the slop pail 100 through the vent hole 323, thereby ventilating it more smoothly.

The rest of the structure and the features are the same as those of embodiment 1, and the details are not described here.

It should be noted that, in the above embodiments 1-3, the filter plate is provided with a hand-held portion on the side facing the bung, and the retaining wall extends downward from the bung or upward from the filter plate to reserve a space for the hand-held portion above the filter plate. In some additional embodiments, if there is no handle on the filter plate, the blocking wall is horizontally disposed and integrally formed with the barrel cover, when the barrel cover and the sewage tank are assembled in place, a part of the barrel cover completely blocks the upward filter hole of the filter plate, and also can prevent impurities from accumulating on the filter hole on this side, and at this time, the blocking wall can be regarded as a part of the barrel cover. In other additional embodiments, if the filter plate has a portable part, the blocking wall can be horizontally arranged and formed integrally with the barrel cover, but the barrel cover is thicker at the blocking wall and is thick enough to form a groove on the surface of the blocking wall for accommodating the portable part. When the barrel cover and the sewage tank are assembled in place, the filtering holes with upward filtering plates are completely blocked by the blocking wall part of the barrel cover, so that impurities can be prevented from being accumulated on the filtering holes on the side, and the blocking wall can still be regarded as a part of the barrel cover.
