[0018] The outer wall of the valve body 1 is fixed with a mounting shell 7 by bolts, and a mounting cylinder 11 is arranged between the inner walls of the valve body 1.

At this time, the valve flap 5 overcomes the elastic force of the first spring 6 and rises, and the second spring 19 is in a compressed state, and the air path is opened; when the electromagnetic coil 16 is de-energized, under the joint action of the first spring 6 and the second spring 19, the moving iron core 14 is reset, and the valve flap 5 is sealed against the position of the vent 4 again.

[0027] The electromagnetic valve air pump linkage control device provided by the utility model, the electromagnetic drive assembly and the mounting tube 11 constitute the electromagnetic valve, by energizing the electromagnetic valve, it can be transmitted to the cigarette detection device through the circuit to start working, and at the same time, under the joint action of the moving iron core 14, the lever 13 assembly and the support rod 8, the air path can be opened, and the electromagnetic valve power-off valve disc 5 seals the vent 4 under the action of the first spring 6.
