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.

Description

technical field

[0001] The invention relates to a range hood. Background technique

[0002] In the current prior art, a smoke-proof range hood includes a blower fan, a box body, an air outlet arranged on the top of the box body, and two and a half anti-wind pieces, and the two and a half anti-wind pieces are pivotally connected to the air outlet. Existing problems are: the sealing performance between the half-stop upwind sheet and the air outlet is poor, and the half-stop headwind sheet vibrates with noise, and it is rotated by external influences, so it cannot effectively prevent the backwind. Contents of the invention

[0003] The object of the present invention is to provide an electromagnetic suction sealed anti-dumping smoke range hood, which has the characteristics of good sealing performance and can effectively prevent the downdraft.

[0004] The present invention is achieved in the following way: an electromagnetic suction sealing anti-falling smoke range hood, in...
