[0002] Nowadays, with the substantial improvement of people's living standards, the way of traveling by RV has gradually entered people's horizons. The design of RV requires reasonable planning of space layout, reflecting comfort and energy saving, so the utilization of water resources in RV is particularly important. This requires not only arranging enough devices in a small space to ensure functionality, but also saving space so that water resources can be fully circulated and used efficiently.
[0003] However, in most current RV designs, the water outlet of the daily sink is connected to the toilet tank, which is convenient for storing daily sewage in the toilet tank for secondary utilization. However, since RVs are mainly used for outdoor travel, daily wastewater is inevitably mixed with some solid impurities such as mud and sand. These solid impurities enter the water pipes or water tanks and often cause blockage of the water pipes or water tanks. In a high temperature environment, these impurities will also breed bacteria and produce odor.

After the discharge falls freely, high-pressure water flows out from the water inlet on the toilet seat 91 to flush the inside of the toilet seat 91. After the flushing is completed, the second electric valve 94 returns to the normally closed state.
[0040] When the sedimentation area 22 of the water tank 2 needs to be cleaned, the plugging cover 203 is rotated until the plugging cover 203 is separated from the positioning tube 202, and then the plug 201 is pulled out, and the water flow flushes the sedimentation area 22, and the precipitated impurities flow out from the cleaning port.
