A magnet block 2 is arranged in the first cavity 10, an inductance coil 3 is sleeved outside the magnet block 2, an electromagnetic induction driving mechanism is formed between the magnet block 2 and the inductance coil 3, when current is generated in the inductance coil 3, the inductance coil 3 provides electromagnetic driving force for the magnet block 2 along the central axis direction of the inductance coil 3, and under the action of the electromagnetic driving force, the magnet block 2 is close to or far away from the first air port 11.
The magnet block 2 is provided therein with a flow passage 20 for passing an air flow therethrough, the flow passage 20 being for communicating the first air port 11 and the second air port 12 to form an air flow passage. The magnet block 2 is provided with the choke plug 6 corresponding to the first air port 11, and the magnet block 2 can drive the choke plug 6 to enter or exit the first air port 11, so that the first air port 11 is closed or opened. The inner wall of the first cavity 10, which is close to the first air port 11, is provided with a suction plate 4 opposite to the magnet block 2, and a magnetic attraction force is arranged between the suction plate 4 and the magnet block 2.
In this embodiment, since the suction plate 4 is disposed on the inner wall of the housing 1 near the first air port 11, and a magnetic attraction is provided between the suction plate 4 and the magnet block 2, when the magnet block 2 drives the plug 6 near the first air port 11 to close the air flow channel, the inductance coil 3 provides a smaller electromagnetic force for the magnet block 2 to overcome the resistance of the air pressure at the first air port 11 and close the first air port 11 due to the existence of the magnetic attraction between the suction plate 4 and the magnet block 2, so that the electromagnetic valve adapts to a larger air pressure environment with a smaller driving current, and is particularly suitable for some portable weak-current electronic devices. In addition, when the plug 6 needs to be withdrawn from the first air port 11 to open the air flow channel, the high-pressure air flow in the air channel provides assistance, so that the magnetic attraction between the suction plate 4 and the magnet block 2 does not cause excessive interference to the reverse movement of the magnet block 2.
