Embodiment 1
[0054] Such as Figure 2-11 As shown, this embodiment discloses an electronically controlled spool of a flow regulating type. It includes a pulse valve, a water diversion dial 3, a body sleeve 3 and several sealing rings.
[0055]The pulse valve of the present embodiment selects bistable pulse valve 1, and its structure is as follows image 3 shown. Bistable pulse valve 1 includes: shell 11, coil iron core group 12, moving iron core 13, return spring 14, plug 15, upper valve seat 16, rubber membrane 17, lower valve seat 18 and anti-blocking needle spring 19 .
[0056] to combine Figure 5 As shown, the shell 11 is hollow inside, and the inner wall surface is smooth. The coil core set 12 is installed at one end inside the casing 11 , the end of the coil core set 12 is connected to the docking terminal 8 , and the docking terminal 8 extends out of the casing 11 to connect with the external control circuit structure. The moving iron core 13 is installed inside the coil iron...
Embodiment 2
[0066] Such as Figures 12 to 16 As shown, this embodiment discloses an electronically controlled spool of a thermostat type.
[0067] The difference between this embodiment and the first embodiment is that: the body cover 3 is provided with two body water inlets 31 , namely a cold water inlet 311 and a hot water inlet 312 .
[0068] The electronically controlled valve core of this embodiment can realize the functions of controlling the on-off of the water source and adjusting the water temperature.
[0069] The principle of controlling the on-off of the water source is the same as that in the first embodiment.
[0070] The principle of controlling the water temperature is as follows: the cold water inlet 311 is connected with the cold water pipe, and the hot water inlet 312 is connected with the hot water pipe. Turn the bistable pulse valve 1 so that the water diversion dial 2 fixedly connected to it rotates relative to the body sleeve 3 fixed on the external parts, as Fi...
