Abstract

The invention discloses an electromagnetic-sucking sealed type smoke-inversion-preventing extractor hood. The electromagnetic-sucking sealed type smoke-inversion-preventing extractor hood comprises an air blower and a box body, and an air exhaust outlet and two semi-non-return air plates arranged on the box body, wherein the two semi-non-return air plates are pivoted with the air exhaust outlet. The electromagnetic-sucking sealed type smoke-inversion-preventing extractor hood further comprises a sealing plate capable of being folded and bent, a magnet and an electromagnet, wherein a counter bore is formed in the air exhaust outlet; pivotal bases at the two ends of a diameter line are arranged in the counter bore; two half-axle holes are formed on the pivotal bases; the two ends of a supporting plate are fixedly connected with the inner wall of the air exhaust outlet, respectively; the sealing plate capable of being folded and bent is fixedly connected with the two semi-non-return air plates; the N magnet is fixed on the semi-non-return air plates; the electromagnet is fixed on a magnet base; rotary shafts on the semi-non-return air plates are embedded with rotary shaft slots; the edge of the sealing plate capable of being folded and bent is sealed with a bottom plate of the counter bore in a matched manner. The N magnet and the electromagnet are oppositely arranged, so that the sealing plate capable of being folded and bent is pressed by the semi-non-return air plates due to magnetic-sucking effect; the condition that the semi-non-return air plates leave the bottom plate of the counter bore to generate smoke inversion due to external influence can be effectively prevented.
