[0028] Embodiment 1

[0029] See also Figure 1 A range hood includes a smoke extraction component 1 and a smoke baffle 2. The smoke extraction component 1 is provided with an air inlet 11. The smoke baffle 2 is arranged at the air inlet 11 and can be opened or closed by flipping.

[0030] See also Figure 2 to Figure 5 The range hood further comprises a deflector 3 arranged on the side of the smoke baffle 2 facing the air inlet 11. The deflector 3 comprises a first plate 31, a second plate 32 and a third plate 33. The first plate 31 is arranged on the side of the smoke baffle 2 facing the air inlet 11. The first plate 31 is a flat plate and can be tightly arranged on the smoke baffle 2 by bonding and fixed to the smoke baffle 2. Each plate has a first end and a second end opposite to each other. When the smoke baffle 2 is in the open state, the first plate 31 and the second plate 32 both extend in the front-to-back direction, and the first plate 31 extends in the same direction as the smoke baffle 2. At this time, the front ends of the first plate 31 and the second plate 32 are their respective first ends, the rear ends of the first plate 31 and the second plate 32 are their respective second ends, the upper end of the third plate 33 is its first end, and the lower end of the third plate 33 is its second end. The second plate 32 extends backward from the lower end of the smoke shield 2 or a position close to the lower end. Preferably, the second plate 32 gradually tilts upward from front to rear, and the third plate 33 is arranged in the up-down direction. Preferably, the third plate 33 gradually tilts backward from top to bottom.

[0031] The first end of the first plate 31 and the first end of the second plate 32 are arranged correspondingly, the third plate 33 is arranged between the first plate 31 and the second plate 32, the upper end of the third plate 33 is arranged correspondingly to the second end of the first plate 31, and the lower end of the third plate 33 is arranged correspondingly to the second end of the second plate 32. Thus, the three plates form a shape with a roughly triangular longitudinal cross section. In this embodiment, the second plate 32 and the third plate 33 are integrally formed, and the air deflector 3 includes a cover body composed of the second plate 32 and the third plate 33, and the cover body is detachably connected to the first plate 31.

[0032] A flange 311 extending away from the smoke baffle 2 is formed at the second end of the first plate 31. When the smoke baffle 2 is in the open state, the flange 311 extends downward. The first end of the first plate 31 and the first end of the second plate 32 are snap-fitted, and the first end of the third plate 33 abuts against the front side of the flange 311 to form an interference fit. A buckle 321 extending from the second end is provided at the first end of the second plate 32. A pressure bridge 312 is provided on the side of the first end of the first plate 31 away from the smoke baffle 2, and the buckle 321 is snap-fitted with the pressure bridge 312. The pressure bridge 312 is in the shape of a bridge, arched in the direction away from the smoke baffle 2, and the buckle 321 passes through the pressure bridge 312 from front to back and snaps with the pressure bridge 312. To prevent the buckle 321 from detaching from the pressure bridge 312, a protrusion 322 that protrudes in the direction away from the first plate body 31 is formed at the end of the buckle 321 away from the first end of the second plate body 32. The protrusion 322 can be V-shaped. When the buckle 321 and the pressure bridge 312 are engaged, the buckle 321 passes through the pressure bridge 312 from the side of the pressure bridge 312 close to the first end of the first plate body 31, and the protrusion 322 of the buckle 321 passes through the pressure bridge 312 and abuts against the side of the pressure bridge 312 away from the first end of the first plate body 31.

[0033] By installing the first plate 31 on the side of the smoke shield 2 facing the air inlet 11, the cover body composed of the second plate 32 and the third plate 33 can be quickly installed and removed through a simple buckle design. During installation, the buckle 321 and the pressure bridge 312 are provided with a guide when they are pushed in the forward direction for easy installation. After being pushed in place, the buckle 321 pops up and will abut against the pressure bridge 312 to form a self-locking. When disassembly is required, press one end of the buckle 321 towards the smoke shield 2 to make the buckle 321 withdraw from the pressure bridge 312 to achieve disassembly.

[0034] Embodiment 2

[0035] See also Figure 6-7 The air deflector 3 further includes a support plate 34 that supports the inner side of the air deflector 3 . The support plate 34 is disposed between the first plate 31 , the second plate 32 and the third plate 33 .

[0036] The support plate body 34 includes a first support plate body side 341, a second support plate body side 342, and a third support plate body side 343. The first support plate body side 341 abuts against the first plate body 31, the second support plate body side 342 abuts against the second plate body 32, and the third support plate body side 343 abuts against the third plate body 33. The support plate body 34 can abut against the middle position (middle position in the left-right direction) of the first plate body 31, the second plate body 32, and the third plate body 33, respectively.

[0037] The first side 341 of the support plate body is fixedly connected to the first plate body 31, the second side 342 of the support plate body is detachably connected to the second plate body 32, and the third side 343 of the support plate body is detachably connected to the third plate body 33. The first side 341 of the support plate body can be pre-connected with the first plate body 31 as a whole by riveting or bonding. After the second plate body 32 is snap-connected to the first plate body 31, the second plate body 32 is connected to the second side 342 of the support plate body by screws 35. After the third plate body 33 abuts against the flange 311, the third plate body 33 is connected to the third side 343 of the support plate body by screws 35.
