Abstract: A capacitive igniter with a flameout time-delay function is provided. A first terminal of a flameout time-delay circuit is electrically connected with a common connecting point of a charge-discharge circuit and a charging coil L1. A second terminal of the flameout time-delay circuit is electrically connected with a trigger circuit. A third terminal of the flameout time-delay circuit is grounded through a flameout switch S1. By means of the capacitive igniter with the flameout time-delay function, it can be guaranteed that an engine is stably and reliably shut down under the action of the flameout time-delay circuit when the engine needs to be shut down even if the flameout switch S1 is switched off in the flameout process, and the potential safety hazards that the engine works again due to the fact that the flameout switch S1 is switched off in the flameout process can be effectively avoided.

Abstract: A vibrating screen. The vibrating screen includes a vibrator, a screen box and a base. The vibrator includes at least a motor and an eccentric block coupled thereto. Each motor has a main motor shaft (2, 2A, 2B). A rotor winding (12) and a stator winding (11) are mounted at one end of the shaft (2). Another rotor winding (14) and stator winding (13) or a counterweight (5, 500) which is equal to them in weight are mounted at the other end of the shaft (2).
