As shown in fig. 1 to 9, the present embodiment provides a smoke collecting structure, which includes a smoke collecting hood 100, an outer baffle 200 and an inner baffle 300, wherein the outer baffle 200 is annularly disposed, the outer baffle 200 is installed at a smoke inlet of the smoke collecting hood 100, an outer smoke inlet gap 210 is formed between the outer baffle 200 and the smoke collecting hood 100, the inner baffle 300 is alternately sleeved in an annular space of the outer baffle 200, and an inner smoke inlet gap 310 is formed between the inner baffle 300 and the outer baffle 200. A smoke inlet passage 110 is formed between the inner baffle 300 and the smoke collecting cover 100, and the smoke inlet passage 110 is communicated with both the outer smoke inlet gap 210 and the inner smoke inlet gap 310. The inner barrier 300 is movable to adjust the smoke intake area of the left and right sides of the smoke intake passage 110.

It is understood that the outer baffle 200 is a shape matching the smoke inlet of the smoke collecting cover 100, and may be an oval shape, a rectangular shape, etc. The outer barrier 200 of the present embodiment is substantially square (rectangular), that is, the circumferential profile of the outer barrier 200 is square. An outer smoke inlet gap 210 is formed between the outer baffle 200 and the smoke collecting hood 100, that is, an outer smoke inlet gap 210 is formed between the edge of the outer baffle 200 and the side wall of the smoke collecting hood 100, and the outer smoke inlet gap 210 may be a continuous ring shape, that is, a peripheral ring shape is formed along the smoke inlet of the smoke collecting hood 100; also can be that left side, right side and front side set up outer cigarette clearance 210, and the rear side does not set up the mode of advancing cigarette clearance 210 outward, and at this moment, the rear side of outer baffle 200 can directly be connected with the back lateral wall of collection petticoat pipe 100, and simple to operate is swift, and just it is less to the influence of oil smoke suction and exhaust effect.

The inner baffle 300 is adapted to the annular space of the outer baffle 200, and may be oval, square, etc., in this embodiment, the inner baffle 300 is also substantially square, that is, the circumferential profile of the inner baffle 300 is square, the corresponding annular shape formed by the outer baffle 200 is a rectangular ring, and the inner baffle 300 is slightly smaller than the inner edge of the rectangular ring of the outer baffle 200, so that a continuous annular inner smoke inlet gap 310 can be formed between the inner edges of the inner baffle 300 and the outer baffle 200.

The smoke inlet passage 110 formed by the inner baffle 300 and the smoke collecting hood 100 may be actually understood as an edge portion of the smoke collecting chamber or the smoke collecting chamber of the smoke collecting hood 100. The inner smoke inlet gap 310 is actually an annular space, the left side of the inner smoke inlet gap 310 is a gap portion between the left end of the inner barrier 300 and the left end of the outer barrier 200, and the right side of the inner smoke inlet gap 310 is a gap portion between the right end of the inner barrier 300 and the right end of the outer barrier 200. The left side of the smoke intake channel 110 is approximately the position of the smoke intake channel 110 corresponding to the left side of the inner smoke intake gap 310, and the right side of the smoke intake channel 110 is approximately the position of the smoke intake channel 110 corresponding to the right side of the inner smoke intake gap 310.

Preferably, the inner barrier 300 of the present embodiment is disposed at a side of the outer barrier 200 facing the smoke collecting chamber of the smoke collecting cover 100 to facilitate the movement of the inner barrier 300.

It should be noted that, corresponding to the case where two cooking holes are commonly used at the same time, the smoke collecting structure of the present embodiment is in a normal state, and the inner baffle 300 is disposed centrally. Meanwhile, the inner baffle 300 can move, thereby adjusting the intake air amount of the corresponding side. There is no clear boundary between the inner smoke inlet gap 310 and the smoke inlet channel 110, and when the inner baffle 300 moves, the smoke inlet areas on the left and right sides of the inner smoke inlet gap 310 and the smoke inlet areas on the left and right sides of the smoke inlet channel 110 can be adjusted simultaneously, or the smoke inlet areas on the left and right sides of the smoke inlet channel 110 can be adjusted singly. Through adjusting the area of advancing the cigarette on left side and right side, reach the purpose of adjusting left and right air inlet volume, in this embodiment, when the air inlet area increase of one side usually, the air inlet area of opposite side reduces.
