[0027] A smoke exhaust duct 8 and a housing 9; the housing 9 is fixed to the wall through a bracket and is connected to the ceiling at the top. The smoke exhaust duct 8 is arranged in the housing 9 and is connected to the flue, and structures such as a smoke exhaust fan and a check valve are arranged in the smoke exhaust duct 8.

[0028] The smoke exhaust machine housing 4 and the suction air cover plate 1; the smoke exhaust machine housing 4 is connected and fixed to the bottom of the housing 9, and is communicated with the smoke exhaust duct 8 at the top. An air inlet hole is reserved in the center of the bottom, and a control panel 13, a light shielding plate 14 and a lighting lamp tube 15 are sequentially arranged on the front side of the bottom (from front to back). A pull slot hole 5 is also reserved on the front side wall of the smoke exhaust machine housing 4 (a hole is opened on the front side wall of the smoke exhaust machine housing 4, and U-shaped chutes with opposite openings are respectively formed on the left and right inner side walls). The suction air cover plate 1 is a plate body structure with a suction air port 16 reserved, and is arranged corresponding to the air inlet hole. The rear end is hinged to the smoke exhaust machine housing 4, and the front end is fixed to the smoke exhaust machine housing 4 with screws.

[0029] Oil mesh 10, oil mesh fixing bracket 11, rotary fixing structure and oil cup 12; As Figure 5 shown, the top of the oil mesh fixing bracket 11 is a circular ring structure and is fixedly connected to the smoking air duct 8 (a connecting plate is provided inside the smoking air duct 8). The bottom is a disc structure and is connected to the top circular ring through struts evenly arranged in the circumferential direction. The oil mesh 10 is a hollow structure (funnel-shaped) adapted to the oil mesh fixing bracket 11 and is placed and fixed (screw-fixed) on the oil mesh fixing bracket 11. The rotary fixing structure includes a limit card slot 17 and a fixing block 18. The fixing block 18 is an inverted L-shaped part and is arranged in three along the circumferential direction on the inner bottom wall of the oil cup 12. The limit card slot 17 is an arc-shaped notch formed at the bottom of the oil mesh fixing bracket 11, and three are arranged corresponding to the fixing block 18. The vertical section of the fixing block 18 is movably fitted in the limit card slot 17. After fitting, the bottom of the oil mesh fixing bracket 11 is clamped between the bottom wall of the oil cup 12 and the horizontal section of the fixing block 18, and a straight notch for assembling and fitting with the fixing block 18 is formed at one end of the limit card slot 17.

[0031] In the specific implementation of this embodiment:

[0032] During use, the lighting and the smoking fan are turned on through the control panel 13. The oil fume is captured by the upper air suction cover plate 1 and enters the range hood housing 4 from the air suction port 16. When passing through the filter paper 3, most of the oil stains are filtered and absorbed by the filter paper 3, and then after being separated from the waste oil by the oil mesh 10, it is discharged through the smoking air duct 8. The waste oil slides down and is collected in the oil cup 12.

[0033] During cleaning, turn off the smoking fan. Pull out the installation frame 2 from the range hood housing 4 through the handle 6 and open the four-corner clips 7 to replace the filter paper 3. The old filter paper 3 is directly discarded. After the new filter paper 3 is fixed, insert the installation frame 2 back into the draw slot 5 of the range hood housing 4. Clean the oil cup 12 every month. Pull out the installation frame 2 and replace the filter paper 3. At the same time, after removing the screws fixed at the front end of the air suction cover plate 1, turn the air suction cover plate 1 downward to open it, and disassemble the oil cup 12 in the upper smoking air duct 8 from the air inlet hole: Rotate the oil cup 12 so that the fixing block 18 moves to the end of the limit card slot (the end with a notch), then take down the oil cup 12 downward, pour out the waste oil in the oil cup 12 and clean it, and then restore the states of all components after finishing.

[0034] The usage method of the control panel 13, the electrical signal connection method, the smoking fan, and the filter paper are existing mature technologies.

[0035] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, without creative design, the structural manners and embodiments similar to the technical solution should all fall within the protection scope of the present utility model.
