Wherein, the handle is preferably wrapped with heat insulation material, such as bakelite or cloth, so as to prevent user from being scalded, thereby being beneficial to improving user experience.

It should be appreciated that the orientation or positional relationship indicated by the terms "top," "bottom," and the like are based on the orientation or positional relationship shown in the drawings, and are merely for convenience in describing the present invention and simplifying the description, and are not indicative or implying that the apparatus or elements being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

In summary, the range hood mechanism of the present embodiment can filter the oil smoke carried in the air flow and then discharge the clean air flow from the air outlet 102 of the housing, so as to solve the problem that the range hood mechanism in the prior art can only pump the oil smoke to a short distance, which results in that the oil smoke is diffused in the room and causes pollution.

According to an embodiment of the present invention, in another aspect, there is also provided a cooking apparatus including a range hood mechanism and a pan 6. Wherein, the cooker body 6 of the cooking fume suction mechanism provided in the embodiment 1 is arranged on the shell 1 of the cooking fume filtering mechanism.

The cooking device of the second aspect of the present invention includes or uses the oil fume suction mechanism of the first aspect of the present invention, so that the cooking device has the beneficial effects that the oil fume carried in the air flow can be filtered and then the clean air flow is discharged from the air outlet 102 of the shell, and the problems that the oil fume is diffused indoors and causes pollution due to the fact that the oil fume can only be pumped out to a short distance in the oil fume suction mechanism in the prior art can be overcome.

The above description is merely a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily make modifications or variations within the technical scope of the present invention disclosed herein, and such modifications or variations are intended to be included in the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims. The technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
