3. The electromagnetic valve according to claim 1 or 2, characterized in that the first fluid passage and the second fluid passage are located on both sides in the axial direction of the electromagnetic coil, respectively.
4. The electromagnetic valve according to claim 1 or 2, wherein the spool includes a first spool unit and a second spool unit, and the electromagnetic coil is configured to drive the first spool unit and the second spool unit to move relatively or away from each other when energized; or the electromagnetic coil is configured to drive the first valve core unit and the second valve core unit to move in the same direction after being electrified; or,
the valve core is of an integrated structure.
5. The electromagnetic valve according to claim 4, wherein the electromagnetic coil comprises a first electromagnetic coil unit and a second electromagnetic coil unit, and the first electromagnetic coil unit and the second electromagnetic coil unit are electrified in opposite directions or in opposite winding directions to drive the first valve spool unit and the second valve spool unit to move oppositely or oppositely.
6. The electromagnetic valve according to claim 5, wherein said first electromagnetic coil unit and said second electromagnetic coil unit are connected in parallel to the same power source.
7. The electromagnetic valve according to claim 1 or 2, wherein the first fluid channel comprises a first water inlet channel, a first water outlet channel and a first blocking structure arranged between the first water inlet channel and the first water outlet channel, the first blocking structure is provided with a first water inlet hole, and the valve core is provided with a first plug for opening and closing the first water inlet hole; and/or the presence of a gas in the gas,
the second fluid channel comprises a second water inlet channel, a second water outlet channel and a second blocking structure arranged between the second water inlet channel and the second water outlet channel, a second water inlet hole is formed in the second blocking structure, and a second plug used for opening and closing the second water inlet hole is arranged on the valve core.
8. The solenoid valve as claimed in claim 7, wherein said first plug is located on a side of said first water inlet hole adjacent to said solenoid coil; and/or the presence of a gas in the gas,
the valve core comprises a rod part, the rod part penetrates through the second water inlet hole, the penetrating part is provided with the second plug, and the outer diameter of the rod part is smaller than the aperture of the second water inlet hole.
9. The solenoid valve according to claim 1 or 2, further comprising a first valve body in which the first fluid passage is formed and/or a second valve body in which the second fluid passage is formed.
10. The solenoid valve of claim 9 further comprising a housing, said solenoid coil being disposed within said housing, said first valve body and/or said second valve body being mounted to said housing.
11. A water purifier, characterized in that a water path of the water purifier is provided with a solenoid valve according to any one of claims 1-10.
12. A water dispenser, characterized in that a water path of the water dispenser is provided with an electromagnetic valve according to any one of claims 1-10.
