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

Referring to fig. 1 to 3 and 7, a range hood includes an air intake assembly 1 and a fan frame 2 disposed above the air intake assembly 1, wherein a fan system (not shown) is disposed in the fan frame 2. The air inlet component 1 is communicated with the fluid in the fan frame 2. The thickness of the air intake component 1 in the front-back direction is smaller than that of the fan frame 2, and the thickness of the air intake component 1 can be adjusted, wherein the front side is the side close to a user in a use state, and the back side is the side far away from the user in the use state.

The whole range hood is divided into the two parts by splitting, and when the assembly line is assembled, the whole range hood is assembled into the two parts and is placed into a package after the assembly is finished. The detachable connection is realized between the air inlet component 1 and the fan frame 2 through a connecting structure. The top of the air intake assembly 1 has an opening 12, and the fan frame 2 is connected to the opening 12, and the fan frame 2 and the air intake assembly 1 are in fluid communication through the opening 12. The air inlet component 1 is positioned at the edge of the opening and provided with an upward extending mounting flange 11, the fan frame 2 is provided with four side walls 21 which are arranged at intervals from front to back and arranged at intervals from left to right, and the connecting structure is connected to the bottom of the mounting flange 11 and each side wall 21 of the fan frame 2.

Referring to fig. 3 to 7, the connecting structure includes a first plate 31 and a second plate 32 which can be connected to each other, the first plate 31 being held on the outer side of the mounting flange 11 away from the fan frame 2, and the second plate 32 being held on the inner side of the mounting flange 11 close to the fan frame 2. A mounting groove 211 depressed toward the inside of the blower housing 2 may be formed on an outer surface of the side wall 21 of the blower housing 2, and the second plate 32 may be disposed in the mounting groove 211, thereby allowing the mounting place of the intake assembly 1 and the blower housing 2 to be attached. The first plate 31 and the second plate 32 may be secured by fasteners 33, and the fasteners 33 may also extend through the side walls 21 of the fan frame 2 to secure the fan frame 2 to the attachment structure. Preferably, the fastener 33 may be a screw.

The second plate 32 has a protrusion 321 formed facing away from the first plate 31, a receiving groove 322 is formed in the protrusion 321, the connecting structure further includes an elastic member 34 and a positioning member 35, and the elastic member 34 is disposed in the receiving groove 322. One end of the elastic element 34 abuts against the wall surface of the protrusion 321 away from the first plate 31, and the other end is connected to the positioning element 35. The mounting flange 11 is provided with a positioning hole 111, and the positioning member 35 can pass through the positioning hole 111 from the side of the mounting flange 11 close to the side wall 21 of the wind turbine frame 2, so as to fix the connecting structure with the wind inlet assembly 1. The elastic member 34 keeps the positioning member 35 from tending to pass through the positioning hole 111. When the disassembly is needed, the fastening member 33 is disassembled, and then the positioning member 35 is pressed from the side of the mounting flange 11 away from the side wall 21 of the wind turbine frame 2 to be withdrawn from the positioning hole 111, so that the elastic member 34 is compressed under the force, thereby completing the disassembly of the wind intake assembly 1 and the wind turbine frame 2. Preferably, the positioning member 35 is a marble. Alternatively, the positioning member 35 may be a resilient claw or the like.

In order to prevent oil smoke from escaping due to a gap existing at the installation position of the air inlet assembly 1 and the fan frame 2, the range hood further comprises a flexible pad 4, and referring to fig. 3, 4 and 8, the flexible pad 4 comprises a pad body 41 which is approximately U-shaped, and the pad body 41 is opened downwards to clamp the installation flange 11 from the top of the installation flange 11. One end of the cushion body 41 between the mounting flange 11 and the side wall 21 of the blower frame 2 is formed with an extension 42 extending toward the side wall 21 and abutting against the side wall 21. Therefore, the flexible pad 4 seals the installation positions of the air inlet assembly 1 and the fan frame 2, and oil smoke is prevented from escaping from the gap of the installation positions.

Because the flexible cushion 4 is a soft cushion and is filled between the air inlet component 1 and the fan frame 2, the air inlet component can play a role of buffering in addition to the sealing effect, vibration transmitted by the upper fan frame 2 passes through the flexible cushion, the vibration is greatly reduced, and the vibration of the whole air conditioner is effectively improved.
