Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1, a range hood comprises a fume collecting hood 1, a fan frame 2 located above the fume collecting hood 1 and an air intake assembly 3 located below the fume collecting hood 1.

Referring to fig. 3, a first air inlet 11 transversely arranged is formed in the smoke collecting cover 1, such as the bottom of the smoke collecting cover 1, and a fan system 21 communicated with the first air inlet 11 is arranged in the fan frame 2. The air intake assembly 3 comprises a box body 32 extending downwards from the rear side of the smoke collecting cover 1, a second air inlet 31 which is longitudinally arranged and communicated with the fan system 21 is arranged on the front side of the box body 32, and the second air inlet 31 is positioned on the rear side of the first air inlet 11, so that the effects of back suction and side suction can be realized. The case 32 is hollow and the top thereof communicates (is in fluid communication) with the inside of the fan frame 2. Therefore, the oil smoke can enter the fan frame 2 through the first air inlet 11 and the second air inlet 31 and be discharged from the top of the fan frame 2.

First cigarette board 4 that transversely extends is provided with the below interval of first air intake 11, and the front side interval of second air intake 31 is provided with longitudinally extending second cigarette board 5, and first cigarette board 4 is located the front side of second cigarette board 5. A first circular suction channel is formed between the first smoke baffle 4 and the first air inlet 11, and a second circular suction channel is formed between the second smoke baffle 5 and the second air inlet 31. The bottom of the second smoke baffle 5 is formed with an inclined part 51 which is inclined towards the front side gradually from top to bottom, so that the smoke gathering area is enlarged, and the oil smoke suction efficiency of the bottom of the second smoke baffle 5 is improved. In this embodiment, the first smoke baffle 4 and the second smoke baffle 5 are integrally formed, and the rear end of the first smoke baffle 4 is connected with the top end of the second smoke baffle 5.

Referring to fig. 2 and 3, the first smoke baffle 4 is connected with the smoke collecting hood 1 through a buckle assembly 7, and the second smoke baffle 5 is connected with the box body 32 through the buckle assembly 7. The fastening assembly 7 comprises fastening blocks 71 respectively arranged on the first smoke baffle 4 and the second smoke baffle 5 and fastening seats 72 respectively arranged on the smoke collecting hood 1 and the box body 32.

The range hood further comprises an oil screen 6, the upper end of the oil screen 6 is connected with one side, close to the second air inlet 31, of the second smoke baffle 5, the lower end of the oil screen extends to the inner side of the box body 32 through the second air inlet 31, and therefore the condensed oil on the first smoke baffle 4 and the second smoke baffle 5 can be guided into the inner side of the box body 32 through the oil screen 6 and finally guided into the oil cup. In order to guide the condensed oil on the first smoke baffle 4 to the second smoke baffle 5, the first smoke baffle 4 is inclined from front to back.

Referring to fig. 3, the fan system 21 is a dual air inlet system, and includes a main air inlet 211 disposed toward the rear, that is, the main air inlet 211 faces toward the side close to the wall, so that the radiation noise at the inlet of the fan system 21 can be reduced. The main air inlet 211 corresponds to the second air inlet 31, the oil smoke sucked from the second air inlet 31 enters the main air inlet 211 of the fan system 21 through the air duct directly sucked in the air inlet assembly 3, and the oil smoke escaping from the second air inlet 211 is sucked from the first air inlet 11 above and enters the fan system, so that the oil smoke can be effectively prevented from escaping, and the range hood is good in effect. The secondary air inlet, not shown, of the fan system 21 is directed forwardly.

When the oil smoke rises, under the action of the second smoke baffle 5, the oil smoke is sucked from the bottom, the left side and the right side of the second circular suction channel between the second smoke baffle 5 and the second air inlet 31, the oil smoke which is not sucked rises upwards and meets the first smoke baffle 4, and the oil smoke is sucked from the periphery of the first circular suction channel between the first smoke baffle 4 and the first air inlet 11, so that the oil smoke is prevented from escaping.

Daily user in the clearance, directly clean the integral type first keep off the surface of cigarette board 4 and second keep off cigarette board 5 can, if the clean inside flow way of needs, only need split buckle subassembly 7 just can lift first keep off cigarette board 4 and second and keep off cigarette board 5, then clean inside flow way has promoted the convenience of clean clearance.

The term "fluid communication" as used herein refers to a spatial relationship between two components or portions (hereinafter collectively referred to as a first portion and a second portion), i.e., a fluid (gas, liquid or a mixture of both) can flow along a flow path from the first portion or/and be transported to the second portion, and may be directly communicated between the first portion and the second portion, or indirectly communicated between the first portion and the second portion via at least one third member, which may be a fluid passage such as a pipe, a channel, a duct, a flow guide, a hole, a groove, or a chamber allowing the fluid to flow therethrough, or a combination thereof.
