[0046] The oil fume extraction device of the present invention includes an oil fume extraction mechanism 10 and a support frame 30 for supporting the component 20 to be extracted of oil fume. The oil fume extraction mechanism is arranged on the support frame 30. When the component 20 to be extracted of oil fume needs to extract oil fume, the oil fume extraction mechanism 10 extracts the oil fume emitted by the component 20 to be extracted of oil fume. The oil fume extraction mechanism 10 includes a first oil fume extraction component 40 and a second oil fume extraction component 50. The first oil fume extraction component 40 is arranged on the side of the component 20 to be extracted of oil fume. The first oil fume extraction component 40 has a first air inlet 41. The first air inlet 41 is arranged on the side of the first oil fume extraction component 40 facing the component 20 to be extracted of oil fume.

The second oil fume extraction component 50 is arranged above the component 20 to be extracted of oil fume. The second oil fume extraction component 50 has a second air inlet 51. The second air inlet 51 is arranged on the side of the second oil fume extraction component 50 facing the component 20 to be extracted of oil fume.

The oil fume mechanism is arranged on the support frame 30, relatively close to the smoke outlet position. Moreover, the oil fume emitted by the component 20 to be extracted of oil fume towards the side and upwards is respectively extracted by the first oil fume extraction component 40 and the second oil fume extraction component 50.

[0047] In this embodiment, the side of the first oil fume extraction component 40 facing the component 20 to be extracted of oil fume has a plurality of first air inlets 41, and the plurality of first air inlets 41 are arranged at intervals on the first oil fume extraction component 40; and / or, the side of the second oil fume extraction component 50 facing the component 20 to be extracted of oil fume has a plurality of second air inlets 51, and the plurality of second air inlets 51 are arranged at intervals on the second oil fume extraction component 50.

[0048] During specific implementation, the plurality of first air inlets 41 and the plurality of second air inlets 51 are respectively arranged at intervals on the first oil fume extraction component 40 and the second oil fume extraction component 50, so that the oil fume extraction mechanism 10 has more air inlets to absorb oil fume, and the oil fume emitted towards different directions and positions can be absorbed by the plurality of first air inlets 41 and the plurality of second air inlets 51 arranged at intervals, avoiding the leakage of oil fume and enhancing the oil fume extraction effect of the oil fume extraction mechanism 10.

[0049] In this embodiment, the first oil extraction component 40 has a first air outlet 42 and a first air duct 43.

When the first oil fume extraction component 40 is in the first working position and the second oil fume extraction component 50 is in the second working position, the third side wall 54 covers the communication opening 46 to close the communication opening 46. The setting of the communication opening 46 enables the second oil fume extraction component 50 to have a space for rotation. The second oil fume extraction component 50 can be rotated to the second working position to extract oil fume from the component 20 to be extracted with oil fume.

[0062] Specifically, the exhaust component 60 having the exhaust chamber 61, the first opening 62 and the third opening 64 enables the second oil extraction component 50 to discharge the extracted oil fume into the third opening 64 through the second exhaust port 52, so that the oil fume passes through the exhaust chamber 61 and is discharged to the first through hole 31 at the first opening 62, realizing the transfer and discharge of the oil fume.

[0086] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0087] The oil fume extraction device of the present invention includes an oil fume extraction mechanism 10 and a support frame 30 for supporting the component 20 to be extracted of oil fume. The oil fume extraction mechanism is arranged on the support frame 30. When the component 20 to be extracted of oil fume needs to have its oil fume extracted, the oil fume extraction mechanism 10 extracts the oil fume emitted by the component 20 to be extracted of oil fume. The oil fume extraction mechanism 10 includes a first oil fume extraction component 40 and a second oil fume extraction component 50. The first oil fume extraction component 40 is arranged on the side of the component 20 to be extracted of oil fume. The first oil fume extraction component 40 has a first air inlet 41. The first air inlet 41 is arranged on the side of the first oil fume extraction component 40 facing the component 20 to be extracted of oil fume. The oil fume emitted by the component 20 to be extracted of oil fume towards the side enters the first air inlet 41 and is discharged by the exhaust structure. The second oil fume extraction component 50 is arranged above the component 20 to be extracted of oil fume. The second oil fume extraction component 50 has a second air inlet 51. The second air inlet 51 is arranged on the side of the second oil fume extraction component 50 facing the component 20 to be extracted of oil fume. The oil fume emitted by the component 20 to be extracted of oil fume upwards enters the second air inlet 51 and is discharged by the exhaust structure. The oil fume extraction mechanism is arranged on the support frame 30 and is relatively close to the smoke outlet position. Moreover, the oil fume emitted by the component 20 to be extracted of oil fume towards the side and upwards is respectively extracted by the first oil fume extraction component 40 and the second oil fume extraction component 50. The first oil fume extraction component 40 and the second oil fume extraction component 50 make the working area of the component 20 to be extracted of oil fume form a semi-closed structure, where the oil fume is only generated and absorbed inside, and the oil fume extraction effect is good, reducing the situation of oil fume overflow.
