Since the embodiments disclosed in the present utility model can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0023] See also Figure 1-2 A range hood includes a housing 1, wherein the housing 1 includes an air inlet 11 and an air outlet 12. The air inlet 11 is arranged downward, and the air outlet 12 is arranged upward.

[0024] The range hood further comprises a fan frame 7 arranged on the housing 1, and a fan 8 is arranged in the fan frame 7. The fan 8 comprises a fan input end 81, and the fan input end 81 is arranged corresponding to the air outlet 12 of the housing 1.

[0025] An activated carbon filter module 2 is disposed in the housing 1, and the activated carbon filter module 2 is located between the air inlet 11 and the air outlet 12. The activated carbon filter module 2 includes an activated carbon filter module input end 21 and an activated carbon filter module output end 22. The activated carbon filter module input end 21 is disposed corresponding to the air inlet 11, and the activated carbon filter module output end 22 is disposed corresponding to the air outlet 12. After the oil smoke enters from the air inlet 11, it is filtered by the activated carbon filter module 2 and flows out from the air outlet 12.

[0026] The range hood further includes a first baffle assembly 3 and a second baffle assembly 4, both of which are arranged inside the housing 1. The first baffle assembly 3 is arranged between the activated carbon filter module input end 21 and the air inlet 11, and the first baffle assembly 3 can open or close the fluid communication channel between the activated carbon filter module input end 21 and the air inlet 11. The second baffle assembly 4 is arranged between the activated carbon filter module output end 22 and the air outlet 12, and the second baffle assembly 4 can open or close the fluid communication channel between the activated carbon filter module output end 22 and the air outlet 12. The actions of the first baffle assembly 3 and the second baffle assembly 4 are both controlled by the control module 9.

[0027] The first baffle assembly 3 and the second baffle assembly 4 are both telescopic structures. The first baffle assembly 3 includes a first telescopic plate 31 and a second telescopic plate 32, which are respectively arranged on opposite sides of the input end 21 of the activated carbon filter module, and the first telescopic plate 31 and the second telescopic plate 32 can be extended in a direction close to each other. The second baffle assembly 4 includes a third telescopic plate 41 and a fourth telescopic plate 42. The third telescopic plate 41 and the fourth telescopic plate 42 are respectively arranged on opposite sides of the output end 22 of the activated carbon filter module, and the third telescopic plate 41 and the fourth telescopic plate 42 can be extended in a direction close to each other. When the first baffle assembly 3 and the second baffle assembly 4 are fully unfolded, the first baffle assembly 3, the second baffle assembly 4 and the inner side of the shell 1 can constitute a closed space for accommodating the activated carbon filter module 2.

[0028] See also Figure 2-3 The range hood further comprises a vibrating member 5 disposed on the first telescopic plate 31 and the second telescopic plate 32, and the vibration generated by the vibrating member 5 directly or indirectly acts on the activated carbon filter module 2. A water-oil absorber 10 for receiving the water vapor vibrated off the activated carbon filter module 2 is disposed below the activated carbon filter module 2.

[0029] The range hood further comprises a sensor 6 which can control the deployment range of the first baffle assembly 3 according to the sensing signal.

[0030] When cooking (such as eating hot pot), the fan 8 is turned on, and the sensor 6 senses the oil smoke, odor, tilt direction and air inlet wind speed generated in the pot, and feeds the information back to the control module 9. The control module 9 controls the size and position of the first baffle assembly 3 to close, and controls the second baffle assembly 4 to fully open. Since the oil smoke and odor generated by the uneven heating of the pot are tilted, it is easy to reach the critical edge position of the air inlet 11, so the first telescopic plate 31 and the second telescopic plate 32 of the first baffle assembly 3 can be opened asymmetrically to prevent the oil smoke from escaping.

[0031] After use, the fan 8 is turned off, and the vibrating member 5 of the first telescopic plate 31 and the second telescopic plate 32 is started to vibrate, so as to vibrate the water vapor adsorbed in the activated carbon filter module 2 down, and the water vapor falls to the water-oil absorber 10 and is absorbed thereafter, and the activated carbon in the activated carbon filter module 2 that is stuck together and agglomerated due to water absorption is vibrated away, so as to prevent the increase of local wind resistance and the influence of the activated carbon adsorption effect, thereby improving the life of the activated carbon filter module 2.

[0032] After completing the above work, the control module 9 controls the first baffle assembly 3 and the second baffle assembly 4 to be completely closed, and the first baffle assembly 3, the second baffle assembly 4 and the inner side of the shell 1 together form a closed space for accommodating the activated carbon filter module 2, preventing the activated carbon filter module 2 from absorbing water vapor and odor molecules in the air, thereby greatly improving the life of the activated carbon filter module 2.

[0033] The "fluid communication" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
