Description

Technical Field

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

[0002] In the related art, cleaning appliances need to complete cleaning by sucking away dirt with gas. However, during the process of sucking gas, the sewage in the sewage tank will enter the air outlet along with the suction of gas, causing water ingress to the fan. The existing technology mostly adopts extending the airflow path to avoid the above situation, that is, by setting a partition on the bottom side of the box cover, the partition divides the sewage tank cavity into a U-shaped cavity, the water inlet and outlet of the water inlet pipe are set at the top of one side of the U-shaped cavity, and the air outlet is set at the top of the other side of the U-shaped cavity. Although the above scheme can avoid the possibility of sewage being directly sucked into the air outlet, the suction response time of the cleaning equipment will also be prolonged due to the extension of the airflow path, thereby affecting the user experience.

[0003] Therefore, in view of the shortcomings of the prior art, it is necessary to design a sewage tank structure to solve the above problems. Utility Model Content

[0006] The preferred technical solution is: the height of the upper edge of the window is lower than the height of the outlet end of the water inlet pipe.

[0007] The preferred technical solution is: a mesh plate is fixedly provided at the bottom end of the partition, and the mesh plate is arranged close to the water inlet pipe.

[0008] The preferred technical solution is: sealing strips for sealing connection with the inner wall of the box body are embedded on both sides of the partition.
