Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Referring to fig. 1 to 3, a range hood includes a housing 1, an air inlet 11 formed in a front side of the housing 1, a smoke barrier assembly 2 capable of opening or closing the air inlet 11, and a movement mechanism 3 capable of driving the smoke barrier assembly 2 to move.

Referring to fig. 4 to 7, the smoke barrier assembly 2 includes a smoke barrier body 21, and the smoke barrier body 21 includes a smoke barrier body inner side 211 facing the inner side of the housing 1.

The inner side 211 of the smoke baffle body is provided with a hand clamping prevention device 4. The anti-pinch device 4 comprises a trigger plate component 41, and the trigger plate component 41 and the inner side 211 of the smoke baffle body are arranged at intervals. The anti-pinch device 4 further comprises a sensor component 42 which can sense the deformation of the trigger component 41 relative to the inner side 211 of the cigarette blocking plate body, so that the moving mechanism 3 drives the cigarette blocking plate component 2 to move reversely (reversely to the current moving direction).
