On the other hand, it can also enable the oil stains adhered to the cover plate body 241 and the smoke guide portion 242 to flow into the main smoke collecting chamber 100, so as to avoid the oil stains from being exposed and causing oil leakage in the range hood.

[0048] Optionally, the front portion of the lower side panel 23 is further provided with a raised smoke guide portion 231 located in front of the auxiliary air inlet 201, the rear end of the raised smoke guide portion 231 is connected to the front end of the auxiliary air inlet 201, and the front end of the raised smoke guide portion 231 is inclined downward from back to front to guide the oil smoke, so that the oil smoke can be guided to the auxiliary air inlet 201, thereby ensuring the smoothness of the oil smoke flow and thereby improving the smoking effect.

[0049] Optionally, the area of ​​the auxiliary air inlet 201 is larger than the area of ​​the auxiliary air outlet 202, so that the flow speed of the oil smoke can be further increased, thereby accelerating the exhaust speed of the oil smoke and improving the smoking effect.

[0050] Optionally, two auxiliary air inlets 201 are provided, one auxiliary air inlet 201 is provided on the left side of the lower side plate 23, and the other auxiliary air inlet 201 is provided on the right side of the lower side plate 23. By providing two auxiliary air inlets 201, the air inlet area is increased.

[0051] Optionally, it further includes a lighting lamp 4 and a control panel 521. The lighting lamp 4 is mounted on the lower side plate 23 and is located between the two auxiliary air inlets 201, so that the two auxiliary air inlets 201 can be respectively arranged corresponding to the two burners arranged below the range hood to improve the smoke extraction effect. The control panel 521 is arranged in the cavity 20 and connected to the rear side of the panel 21. The control panel is arranged in the cavity 20 so that the control panel 521 can avoid the flow path of the oil smoke, and prevent the oil from entering the control panel 521 and affecting the control panel 521.

[0052] Optionally, a bellows assembly 3 is further included, and the bellows assembly 3 is installed on the upper side of the smoke collecting hood 1 .
