Abstract

The invention discloses a smoke exhaust device which comprises a cover and an airflow generation device. The cover comprises a body and a flue part which is connected with the body and located on the upper side of the body. A smoke collection cavity is formed in the body. The flue part is provided with an oil smoke channel which communicates with the smoke collection cavity. The outer edge of the body is provided with jet orifices which surround the smoke collection cavity. A curved surface smoothly connecting the jet orifices and the inner surface of the smoke collection cavity is formed on the outer edge of the body. Jet flow of the jet orifices is jetted towards the curved face. The airflow generation device is used for inputting airflow into the body. The jet orifices are used for converting the airflow into the jet flow which is jet towards the smoke collection cavity through the curved surface to form a negative pressure area at the outer edge of the body. In this way, the high-speed airflow jetted out of the jet orifices can form the negative pressure area at the outer edge of the body, and accordingly, air around the body can be entrained and gathered into the smoke collection cavity and finally enters the oil smoke channel to exhaust oil smoke, so that the suction range of the smoke exhaust device is enlarged.

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 suction force of the smoke exhaust device is mainly concentrated near the suction port in the center of the smoke exhaust device, and the suction force on the edge of the smoke exhaust device is insufficient, so the oil fume easily escapes from the edge of the smoke exhaust device and spreads toward the user, which makes the smoke exhaustion. The smoke exhaust efficiency of the device is low, which also brings a negative experience to the user. SUMMARY 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 according to the embodiment of the present invention includes a cover body and an air flow generating device,...
