The electric control valve core for adjusting the flow rate can realize the function of controlling the on-off of a water source and adjusting the flow rate.
The principle of controlling the on-off of the water source is that the butt joint terminal 121 is electrically connected with the output terminal 62 of the induction control handle, when the power supply is not connected, as shown in fig. 18, the movable iron core 13 and the plug 15 are positioned below, the plug 15 plugs the pressure relief hole 162, at this time, the water flow direction is shown by an arrow in the figure, and can only flow below the rubber film 17, and can not enter the valve body water outlet 183, and at this time, the water flow is in a water flow off state. As shown in fig. 19, the external control circuit applies a pulse current to the coil core set 12 through the butt-joint terminal 121, the coil is electrified to generate a magnetic field so that the movable iron core 13 moves upwards, the movable iron core 13 drives the plug 15 to separate from the pressure release hole 162, the pressure causes the rubber film 17 to move upwards, and at this time, the water flow direction is shown by an arrow in the figure, and the water flow flows from the water inlet 31 of the body, through the water diversion port 21, into the water inlet 181 of the valve body, flows out through the water outlet 183 of the valve body, flows out through the water outlet 22 of the turntable, and flows out of the water outlet 32 of the body.
The principle of flow regulation is that the bistable pulse valve 1 is rotated to enable the water diversion turntable 2 fixedly connected with the bistable pulse valve to rotate relative to the body sleeve 3 fixed on an external part, when the water diversion opening 21 and the body water inlet 31 are completely overlapped, as shown in fig. 21, the water flow is maximum at the moment, and the overlapped part of the water diversion opening 21 and the body water inlet 31 is reduced in the rotating process, so that the water flow is reduced, as shown in fig. 22.
2. Electric control valve core for temperature regulation
As shown in fig. 23-25, the difference between the electric control valve core and the flow-regulating electric control valve core is that two body water inlets 31, namely a cold water inlet 311 and a hot water inlet 312, are arranged on the body sleeve 3. The electric control valve core 9 can realize the function of controlling the on-off of a 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 flow regulation.
The principle of controlling the water temperature is that a cold water inlet 311 is connected with a cold water pipe, and a hot water inlet 312 is connected with a hot water pipe. The bistable pulse valve 1 is rotated to enable the water diversion turntable 2 fixedly connected with the bistable pulse valve to rotate relative to the body sleeve 3 fixed on the external part, and when the water diversion opening 21 is completely overlapped with the cold water inlet 311 and the hot water inlet 312, as shown in fig. 24, the cold water inflow is the same as the hot water inflow at the moment, and the water temperature is moderate. As shown in fig. 25, in the process of rotating the water diversion turntable 2 toward the cold water inlet 311, the overlapping area of the water diversion opening 21 and the hot water inlet 312 becomes smaller, the inflow amount of hot water is reduced, and at this time, the water temperature is lowered. Similarly, in the process that the water diversion turntable 2 rotates towards the hot water inlet 312, the overlapping part of the water diversion opening 21 and the cold water inlet 311 is reduced, the water inflow amount of the cold water is reduced, and the water temperature is increased at the moment.
The two electric control valve core structures of the invention are consistent with the specification and the size of the common mechanical ceramic valve core, and can be matched. The invention has the significance that the general tap is convenient to upgrade into the induction tap, taking the general tap of the background technology figure 1 as an example, as shown in figure 26, a mechanical ceramic valve core 2', a general handle 3', a decorative cover 4', a set screw 5' and a buckling cap 7 'are removed, an electric control valve core 9 of the embodiment is arranged in a general tap body 1', the electric control valve core 9 is fixed on the general tap body 1 'by adopting an original flange 6', and then an induction control handle is arranged.

The outer wall of the body sleeve of the electric control valve core 9 is provided with an outer wall sealing groove 33, an outer wall sealing ring 43 is arranged in the outer wall sealing groove 33, the peripheries of the end faces of the body water inlet 31 and the body water outlet 32 are provided with an end face sealing groove 34, and an end face sealing ring 44 is arranged in the end face sealing groove 34. The electric control valve core 9 is hermetically arranged in the valve core installation cavity 81 of the tap body 8 through the outer wall sealing ring 43 and the end surface sealing ring 44. The lower end of the body sleeve 3 of the electric control valve core 9 is provided with a lug 35, and the lug 35 is inserted into the positioning hole 82 to fix the electric control valve core 9 and the tap body 8. The flange cover 10 is located between the electric control valve core 9 and the handle, and the flange cover 10 locks the electric control valve core 9 inside the valve core installation cavity 81, in this embodiment, the flange cover 10 is locked with the tap body 8 through threaded connection. Finally, the induction control handle is installed, the positioning rib 23 of the induction control handle is inserted into the clamping groove 112 of the electric control valve core 9, and the butt-joint terminal 121 above the electric control valve core 9 is in contact connection with the output terminal 62 of the induction control handle.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention.
