In addition, the features defined as "first", "second" can explicitly or implicitly include one or more of the features.

[0036] Embodiment one

[0037] Referring to Figures 1-5 An extractor hood, comprising a hood body 1, an air outlet device and a decorative cover 3, the hood body 1 is preferably in a super-thin form, and can also be in other existing forms. It is the same as the prior art, comprising a box body 11 and a fan system 12 arranged in the box body 11.

[0038] The air outlet device is arranged at the air outlet of the hood body 1, part of which is located below the kitchen ceiling 100, and part of which is located above the ceiling 100. In order to avoid the part of the air outlet device located below the ceiling 100 from being exposed, a decorative cover 3 is arranged outside it.

[0039] Along the oil fume flow path, the air outlet device comprises an air outlet cover 21, an air outlet pipe 22 and an adapter structure arranged in sequence. The adapter structure is arranged so that the air outlet pipe 22 can be connected to the smoke exhaust pipe 200 above the ceiling 100.

[0040] Since the air outlet 121 of the fan system 12 of the smoke machine body 1 is usually rectangular (determined by the air outlet of the volute), the air outlet cover 21 is a square-to-round component, that is, the cross section of the air outlet cover 21 is rectangular, and the cross section of the air outlet of the smoke machine body 1 and the cross section of the outlet connected with the air outlet pipe 22 are all rectangular, so that the air outlet pipe 22 with a rectangular cross section can be connected, and the air outlet pipe 22 is an upwardly extending pipe, especially a vertically extending pipe, which is located below the ceiling 100. Thus, through the air outlet cover 21 and the air outlet pipe 22 arranged as described above, compared with a circular pipe, the installation space requirement can be met, and the air outlet area can be increased. In addition, the air outlet pipe 22 is preferably an aluminum foil hose, which can be stretched and contracted to adapt to different ceiling 100 heights and is convenient for transportation.

[0041] In the embodiment, the adapter structure includes a first adapter 23, which includes an adapter body 231, an ear 232 formed on the adapter body 231, and a support 233 for fixing with the decorative cover 3. The adapter body 231 is a square-to-round adapter, which has the same shape and structure as a conventional square-to-round air outlet cover, can be inserted with the air outlet pipe 22, and the bottom of the adapter body 231 can be inserted into the air outlet pipe 22, so that the position of the first adapter 23 in the transverse direction (front-rear and left-right) is limited by the air outlet pipe 22. The adapter body 231 has a rectangular inlet 2311 for the oil fume to enter and a circular outlet 2312 for the oil fume to be discharged, and the outlet 2312 is above the inlet 2311. The adapter body 231 is connected with the air outlet pipe 22 at the inlet 2311, and the inlet 2311 is located below the ceiling 100. The adapter body 231 is connected with the smoke exhaust pipe 200 at the outlet 2312, and the outlet 2312 can be completely located above the ceiling 100 or can be partially located above the ceiling 100 to be connected with the smoke exhaust pipe 200.

[0042] The support 233 is in the shape of a long rod, and the left and right ends thereof are fixed with the corresponding positions of the decorative cover 3, respectively. The ear 232 is formed on the adapter body 231. In the embodiment, the support 233 is arranged on the rear side of the adapter body 231, and the ear 232 is formed on the rear side wall surface of the adapter body 231, and the position of the ear 232 can be close to the inlet 2311 of the adapter body 231. The ear 232 can be hung on the support 233, so that the position of the first adapter 23 as a whole is fixed. The ear 232 includes a first hanging part 2321 and a second hanging part 2322, wherein the first hanging part 2321 extends transversely away from the adapter body 231 (in the installed state, the first hanging part 2321 extends rearward), and the second hanging part 2322 extends downwardly from the rear end of the first hanging part 2321. When the ear 232 is hung, the support 233 can be supported at the junction of the two hanging parts or can be supported on the bottom surface of the first hanging part 2321, so that the position in the up-down direction is limited.

[0043] The decorative cover 3 comprises a cover body 31 and hooks 32 for hanging the cover body 31 to the wall 300, the hooks 32 comprise hook portions 321 and mounting racks 322 connecting the hook portions 321 to the cover body 31.
