The electric control valve core for adjusting the flow rate can realize the functions of controlling the on-off of a water source and adjusting the flow rate.

As shown in fig. 19, the external control circuit supplies a pulse current to the coil iron core group 12 through the docking terminal 121, the coil is energized to generate a magnetic field, so that the movable iron core 13 moves upward, the movable iron core 13 drives the plug 15 to separate from the pressure relief hole 162, the rubber film 17 moves upward under the pressure, and the water flow direction is as shown by the arrow in the figure, and the water flow enters the valve body water inlet 181 from the body water inlet 31 through the water diversion port 21, flows out through the valve body water outlet 183, flows out through the turntable water outlet 22, and flows out through the body water outlet 32.

The principle of adjusting the flow is as follows: the bistable pulse valve 1 is rotated, so that the water diversion rotary disc 2 fixedly connected with the bistable pulse valve and the body sleeve 3 fixed on an external part rotate relatively, as shown in fig. 21, when the water diversion port 21 is completely overlapped with the body water inlet 31, the water flow is maximum at the moment, and in the rotating process, the overlapped part of the water diversion port 21 and the body water inlet 31 is reduced, so that the water flow is reduced, as shown in fig. 22.

Second, temperature regulating type electric control valve core

As shown in fig. 23 to 25, the difference between the electric control valve core and the flow rate adjusting type electric control valve core is as follows: the body sleeve 3 is provided with two body water inlets 31, namely a cold water inlet 311 and a hot water inlet 312. The electric control valve core 9 can realize the functions of controlling the on-off of the water source and adjusting the water temperature. The principle of controlling the on-off of the water source is the same as that of the electric control valve core for regulating the flow rate.

The principle of controlling the water temperature is as follows: the cold water inlet 311 is connected to a cold water pipe, and the hot water inlet 312 is connected to a hot water pipe. The bistable pulse valve 1 is rotated, so that the water diversion rotary disc 2 fixedly connected with the bistable pulse valve and the body sleeve 3 fixed on the external part rotate relatively, as shown in fig. 24, when the water diversion port 21 is completely overlapped with the cold water inlet 311 and the hot water inlet 312, the cold water inflow is the same as the hot water inflow, and the water temperature is moderate. As shown in fig. 25, when the diversion dial 2 rotates in the direction of the cold water inlet 311, the overlapping portion of the diversion port 21 and the hot water inlet 312 becomes smaller, the hot water inflow amount decreases, and the water temperature is lowered at this time. Similarly, in the process that the water diversion turntable 2 rotates towards the hot water inlet 312, the overlapped part of the water diversion port 21 and the cold water inlet 311 becomes smaller, the cold water inflow is reduced, and at the moment, the water temperature is increased.

The two electric control valve core structures of the invention have the same specification and size with the common mechanical ceramic valve core and can be matched.
