[0034] Please refer to Figures 1-5 This utility model provides a range hood, including a smoke collection hood 1 and a housing 3. The smoke collection hood 1 includes an outer shell 11 and a smoke guide plate 12 disposed on the front side of the outer shell 11. The smoke guide plate 12 includes a left smoke guide part 121, a middle smoke guide part 122 and a right smoke guide part 123 connected from left to right. The middle smoke guide part 122 is recessed upward and forms a smoke inlet 1201 and a first smoke outlet 1202 that are interconnected. The smoke inlet 1201 is located below the first smoke outlet 1202. The outer shell 11 includes a left shell 111, a middle shell 112 and a right shell 113 connected from left to right. A second smoke outlet 110 corresponding to the first smoke outlet 1202 is opened on the upper side of the middle shell 112. The first smoke outlet 1202 is disposed in the second smoke outlet 110 and communicates with the second smoke outlet 110 to form a smoke outlet hole. The chassis 3 is equipped with a smoke chamber 30. The lower end of the chassis 3 is provided with an air inlet 301 that communicates with the smoke chamber 30. The smoke outlet is located at the air inlet 301 and communicates with the air inlet 301.

[0035] The range hood provided by this utility model has an upwardly recessed central smoke guide section 122 forming an interconnected smoke inlet 1201 and a first smoke outlet 1202. The first smoke outlet 1202 is positioned within a second smoke outlet 110 to form a smoke outlet hole. This smoke outlet hole is then positioned at the air inlet 301 of the casing 3. This allows the smoke collection chamber 30 formed between the smoke inlet 1201 and the first smoke outlet 1202 to extend from the smoke inlet 1201 to the air inlet 301 of the casing 3, effectively increasing the depth and volume of the smoke collection chamber 30, thereby improving the smoke collection effect. The structure is simple and compact, requiring no additional increase in the size of the range hood, thus maintaining its miniaturization advantage.

[0036] Optionally, the peripheral walls of the first smoke outlet 1202 and / or the second smoke outlet 110 are connected to the peripheral wall of the air inlet 301, thereby facilitating the placement of the smoke outlet at the air inlet 301.

[0037] For example, in this embodiment, the peripheral wall of the second smoke outlet 110 is connected to the peripheral wall of the air inlet 301, which is simple in structure and easy to install.

[0038] Optionally, it also includes a flap assembly 4, which includes a flap body 41 and a drive structure 42 that is pulsatorically connected to the flap assembly 4.

The drive structure 42 can drive the flap body 41 to swing relative to the smoke hood 1 to close or open the smoke inlet 1201.

[0039] Furthermore, the left smoke guide 121 is connected to the left cover 111 by screws, and the right smoke guide 123 is connected to the right cover 113 by screws.

[0040] Optionally, the left smoke guide 121 is connected to the left cover 111 and encloses it to form a first cavity 100, and the right smoke guide 123 is connected to the right cover 113 and encloses it to form a second cavity 200. The drive structure 42 is disposed within the first cavity 100 or the second cavity 200. This allows the first cavity 100 and the second cavity 200 to be relatively isolated from the smoke collection chamber 30. The drive structure 42 or other parts of the range hood can be installed within the first cavity 100 and the second cavity 200, isolating these parts from oil fumes and preventing oil fumes from adhering to them. This also allows the drive structure 42 to be relatively isolated from the smoke collection chamber 30, reducing the adhesion of oil stains to the drive structure 42.

[0041] Furthermore, the drive structure 42 includes a drive motor and a transmission rod. The drive motor is installed in the first cavity 100.

The front end of the oil receiving trough 1203 is located below the casing 3 and the fan 5, and is used to collect oil stains from the inner wall of the casing 3 and the fan 5. The bottom of the oil receiving trough 1203 is inclined downward from front to back, and the rear end of the oil receiving trough 1203 is located above the oil cup 7, so that the oil stains in the oil receiving trough 1203 can flow from front to back to the rear end of the oil receiving trough 1203 and then fall into the oil cup 7.

[0045] Optionally, it also includes an oil receiving structure 6, the upper part of which is located on the lower side of the fan 5 to receive oil stains on the fan 5, and the lower end of which is located above the oil receiving tank 1203 or extends into the oil receiving tank 1203 to facilitate the flow of oil stains into the oil receiving tank 1203.

[0046] Optionally, the smoke guide plate 12 is integrally molded, which has a simple structure, good strength, and good sealing performance, reducing the entry of oil stains into the first cavity 100 and the second cavity 200.
