Description

technical field [0001] The invention relates to an automatic sewage discharge and cleaning device for a pull-type black water tank of a caravan, which belongs to the technical field of caravans. Background technique [0002] The black water tank is a general term for a box containing dirt. The black water tank for a caravan is a box specially used to collect waste water discharged from the toilet in the caravan. It is divided into two categories: fixed and pull-out. Due to the lack of RV campsites and incomplete equipment in China, most RV black water tanks adopt a pull-out structure. During RV travel, black water tanks are one of the essential components in RVs, and often the accumulated sewage and sewage need to be removed. However, the current treatment method for the sewage in the tank is: remove the black water tank from the caravan, drag it to the toilet, sewer or the place where the sewage is stored in the caravan camp, and dump the sewage. The volume of the black wa...
