The piston 23 is provided with a flow restricting means which is a restricting orifice 71 or/and a gap 16 between the piston 23 and the cylinder block 1 or/and a gap 17 between the piston 23 and the heating means 51. A limited flow device is provided on the piston 22, said flow restricting device being the gap between the piston 22 and the cylinder block 1 and/or the gap between the piston 22 and the heating device 51 or/and the temperature-controlled telescopic device 16. The piston 21 is provided with a flow restricting device which is a gap between the piston 21 and the cylinder block 1 and/or a gap between the piston 21 and the heating device 51 or/and a hydraulically sensitive telescopic device 6, 7. The current limiting device can define a cold water velocity through the piston, thereby controlling the mixing speed of the hot and cold water in the discharge chamber, so that the electric water heater is used while heating the water temperature in the cavity being discharged, and the temperature of the mixed cavity is raised. Can also meet the requirements of use.

The piston 23 is further provided with a flow guiding device, which is a flow guiding hole 2, 3 or/and a baffle 14, 15, and has water passing through the gaps 16, 17 between the piston 23 and the cylinder 1. When the water passing area of the diversion hole is larger than the water passing area of the upper piston gap, the flowing water flows into the intermediate layer of the piston 23 through the diversion hole, and under the action of the baffles 14, 15, the newly inflowing cold water is formed. Stable cold water layer.

The temperature-controlled telescopic device 16 disposed at the gap between the piston 22 and the cylinder block 1 , when the cold water having a lower temperature flows, the temperature-controlled telescopic device 16 senses the temperature to close the gap, and reduces the speed at which the cold water enters the hot water end, and the hot water end The mixed water is further heated by the heating pipe heated by the layering. When the water temperature is increased, the temperature-controlled expansion device 16 is contracted, the gap is enlarged, and the speed of the cold water entering the hot water end is raised, and the temperature-controlled expansion device 16 can be made of bimetal with inconsistent heat sensitivity. The composition, the metal sheet induces temperature and thus expands and contracts to open or close the gap, as in the prior art.

The hydraulically sensitive telescopic device 6 and 7 disposed at the gap between the piston 21 and the cylinder block 1 when the water in the cylinder block 1 is heated, the pressure in the cylinder is increased, the elastic material is contracted, the gap is enlarged, and the cold water enters the hot water end. The hydraulically sensitive telescopic devices 6, 7 are made of an elastic material such as aerated rubber and are prior art.
