Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a sewage separation box. Background Art

[0002] Existing cleaning devices such as floor scrubbers and fabric cleaning devices can integrate the functions of vacuuming and water absorption. Such cleaning devices generally include a sewage bucket, on which a suction motor is provided. The working principle is to first spray clean water onto the area to be cleaned, and then wipe it with a roller brush. Under the suction of the suction motor, sewage and solid waste are sucked into the sewage bucket, and the gas sucked into the sewage bucket is separated from the sewage and solid waste in the sewage bucket and discharged to the outside.

[0003] For example, a Chinese patent with publication number CN218044980U discloses a sewage tank, including: a tank body, which is provided with a sewage channel; a separation mechanism, which is contained in the tank body and divides the interior of the tank body into a sewage chamber and a mixing chamber that are connected, and the mixing chamber is located above the sewage chamber along the extension direction of the sewage channel; an air guide hood, which is contained in the tank body and has an air guide chamber; wherein the sewage channel, the mixing chamber and the air guide chamber are connected and jointly define a first separation channel for air flow; the sewage channel, the mixing chamber and the sewage chamber are connected and jointly define a second separation channel to separate solid matter and liquid matter in the sewage. The above-mentioned sewage tank has a relatively complex structure, and the air guide hood and the separation mechanism are set in the tank body, which takes up a large space, and the separation capacity is small.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content
