As shown in fig. 6, the working process of the present invention: when entering the water storage tank from the upper cover 1, water flow can flow through the two small impellers 6 and push the turbulence shaft 7 to rotate, the turbulence shaft 7 rotates to drive the large impeller 8 to rotate, and the blades of the large impeller 8 upwards convey the water flow at the bottom of the water storage tank to be fully mixed with the water flow flowing in from the upper part. The water flow finally flows out through a water outlet 4 at the fully mixed area of the cold water and the hot water.

In the embodiment, the large impeller and the small impeller are made of light-weight temperature-resistant high polymer materials, so that the rotary inertia is small; the blades of the two small impellers 6 are in the direction complementary with the gaps of the blades so as to fully convert the water flow energy. The number of the blades of the large impeller 8 is relatively small, and when the large impeller and the small impeller rotate coaxially, the reverse torque generated by the large impeller 8 is designed to be smaller than the positive torque generated by the two small impellers 6 so as to ensure that the turbulent shaft 7 can rotate normally.

According to the water storage tank, the internal structure of the tank body and the water mixing flow channel are simple, the stirring and mixing of water flow in the water storage tank are realized by combining the turbulence device, the mixing efficiency of cold water and hot water in the water storage tank is improved, the internal flow channel structure is simplified, the production difficulty is reduced, the product consistency is high, and the parts are small and light. In the above embodiments, the can body is not limited to a particular shape, and may be "flat" or cylindrical, etc.; the number of the large and small impellers and the arrangement and direction of the impellers are not limited to the scheme.

The small impeller 6 is positioned in the shaft seat 5, a flow passage at the lower part of the shaft seat 5 serves as a duct of the small impeller 6, and water flow entering the shaft seat 5 can efficiently drive the small impeller 6 to generate rotary motion due to the restricted flow of the duct so as to drive the target impeller, namely the large impeller 8 to rotate. When the turbulence shaft 7 rotates, the large impeller 6 and the small impeller 6 have opposite conveying action directions on the fluid. The small impeller 6 has more and more dense blades than the large impeller 8, and the blades and the blade gaps of the two impellers (or a plurality of impellers) are complementary to fully absorb the water flow energy and convert the water flow energy into the rotational kinetic energy of the turbulent flow shaft 7. The same water flow through the small impeller 6 can generate a greater torque.
