Preferably, the inner diameter of the first return pipe is consistent with that of the output pipe, and the first return pipe is provided with an electric control valve B.

After the technical scheme is adopted, the control module controls the opening degree of the electric control valve, the opening degree of the electric control valve A is in inverse proportion to the opening degree of the electric control valve B, and the backflow amount can be accurately controlled due to the fact that the first backflow pipe is consistent with the inner diameter of the lower liquid pump main pipe, the phenomenon that the lower liquid pump main pipe is separated from the first backflow pipe due to the fact that inner pressure is generated in the pipe is avoided, and normal work cannot be achieved.

Preferably, one end of the first return pipe, which is far away from the output pipe, is provided with a second return pipe, and a water outlet of the second return pipe is aligned with the submerged pump pool.

After the technical scheme is adopted, the backflow pipe can ensure that backflow water can accurately enter the pool, and the phenomenon that the backflow water is sprayed out of the pool due to overlarge water flow is avoided.

Preferably, the second return pipe is connected to the first return pipe by a water pipe connection.

After the technical scheme is adopted, the first return pipe and the second return pipe are detachably connected, so that the first return pipe and the second return pipe are convenient to disassemble and assemble.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

1. the technical scheme of the utility model can keep the water level by matching, avoid frequent switching of equipment, reduce equipment loss and reduce labor cost.

2. The technical scheme of the utility model is matched to accurately control the reflux quantity.

3. The second return pipe ensures that return water can accurately enter the pool, and avoids overlarge water flow from being ejected out of the pool.

4. The water pipe joint is convenient for the disassembly and assembly of the second return pipe.
