the valve body 3 is fixedly arranged at a liquid outlet at the lower end of the water boiling and/or tea making container of the automatic tea set through the main body part 31 of the valve body 3, the main body part 31 of the valve body 3 is basically arranged in the water boiling and/or tea making container, and the second connecting part 32 of the valve body 3 extends downwards from the liquid outlet at the lower end of the water boiling and/or tea making container; fixedly mounting the electromagnetic coil 2 on a bracket for supporting the water boiling and/or tea making container, and electrically connecting the electromagnetic coil 2 with an external controllable power supply; inserting the valve housing 1 into the electromagnetic coil 2; the second connecting portion 32 of the valve body 3 is sealingly connected to the connecting portion 11 of the valve housing 1, in which case the second sealing plug 6 is opened by the abutment 7. The first sealing plug 5 closes the first fluid passage 14 of the valve housing 1.
When the electromagnetic coil 2 is not electrified, the first sealing plug 5 seals the first liquid passing channel 14 of the valve casing 1, and at this time, the liquid passing electromagnetic valve of the embodiment is not electrified.
The electromagnetic force generated after the electromagnetic coil 2 is electrified acts on the first sealing plug 5 to enable the first sealing plug to move upwards so as to open the first liquid passing channel 14 of the valve casing 1, so that the liquid outlet channel of the liquid passing electromagnetic valve of the embodiment is communicated from top to bottom, and liquid in the water heating container and/or the tea making container flows out from the liquid outlet 15 after passing through the first liquid passing gap 31-1 of the valve body 3, the second liquid passing channel 33 of the valve body 3, the liquid passing gap between the sealing butt joint end of the second sealing plug 6 and the valve body 3, the second liquid passing gap 41 of the limiting support seat 4, the liquid passing gap formed between the sealing butt joint end of the first sealing plug 5 and the valve casing 1 and the first liquid passing channel 14 of the valve casing 1 in sequence. When the liquid discharge is needed to be stopped, the power supply of the electromagnetic coil 2 is turned off, the upward acting force of the first sealing plug 5 disappears, and the first sealing plug 5 resets in the valve casing 1 to stop the liquid discharge.
