[0002] In the related art, the oil fume channel of the smoke exhaust device is in insufficient suction. When the smoke exhaust device is working, the oil fume flows through the smoke collection chamber of the smoke exhaust device and then enters the oil fume channel. The path it flows through is long, so in the When the suction at the oil fume channel is insufficient, the oil fume is easy to accumulate, which makes the smoke exhaust efficiency of the smoke exhaust device low

The invention discloses a fume exhaust device comprising a cover body and an airflow generating device. The cover body comprises the body and a flue part. The flue part is connected with the body and located on the upper side of the body. A fume gathering chamber is formed in the body. An oil fume channel is formed in the flue part and communicates with the fume gathering chamber. First flow jetting openings are formed in the inner side of the body. Second flow jetting openings are formed in the outer edge of the body. The first flow jetting openings are separated from the second flow jetting openings. The first flow jetting openings embrace the oil fume channel. A curved face smoothly connected with the first flow jetting openings and the inner surface of the oil fume channel is formed on the inner side of the body. The jetting directions of jetting flows of the second flow jetting openings face the curved face. The second flow jetting openings face the fume gathering chamber. The airflow generating device is used for inputting airflows into the body. The first flow jetting openings are used for converting the airflows into the first jetting flows and jetting the first jetting flows to the oil fume channel through the curved face so as to form a negative pressure area at the oil fume channel. The second flow jetting openings are used for converting the airflows into the second jetting flows and jetting the second jetting flows to the fume gathering chamber in the horizontal direction.
Description
technical field [0001] The invention relates to the technical field of smoke exhaust, in particular to a smoke exhaust device. Background technique [0002] In the related art, the oil fume channel of the smoke exhaust device is in insufficient suction. When the smoke exhaust device is working, the oil fume flows through the smoke collection chamber of the smoke exhaust device and then enters the oil fume channel. The path it flows through is long, so in the When the suction force at the oil fume channel is insufficient, the oil fume tends to accumulate, which makes the smoke exhaust efficiency of the smoke exhaust device low. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the related art. Therefore, the present invention needs to provide a smoke exhaust device. [0004] The smoke exhaust device in the embodiment of the present invention includes a cover body and an air flow generating device, the...
