The following describes the movement of the panel 120 of the range hood 100 between the open state and the closed state:

specifically, as shown in fig. 1, 2, 3 and 4, in a state where the panel 120 is locked with the housing 110, the surface of the panel 120 is pressed, the panel 120 is turned inward under the restriction of the first hinge assembly 170a and the second hinge assembly 170b, the switch assembly 140 is pressed, the movable latch 144 of the press switch 142 is contracted, and simultaneously the interior of the press switch 142 releases the movable latch 144; when the hand presses the top dead center position, the hand releases the hand, the panel 120 is turned up by the pushing force of the gas spring 130, as shown in fig. 7 and 8, since the movable latch 144 of the push switch 142 is released to the open state, the panel 120 is continuously pushed and turned up by the pushing force of the gas spring 130, and when the panel 120 is turned up to the top dead center of the stroke of the gas spring 130, the panel stops, and the turning up action of the panel 120 is completed.

Further, as shown in fig. 1, 2, 3 and 4, in a state that the panel 120 and the housing 110 are separated, the surface of the panel 120 is pressed, the panel 120 is turned inward under the limitation of the first hinge assembly 170a and the second hinge assembly 170b, and since the panel 120 is continuously pushed by the gas spring 130, a human hand needs to continuously apply pressure on the panel 120 until the bottom dead center of the stroke of the gas spring 130 in a closed state of the panel 120 is pressed. At this time, the push switch 142 is pressed, and the movable latch 144 is retracted and snapped into the latch catch 148 of the mating member 146, and at the same time, as shown in fig. 5 and 6, the switch assembly 140 is locked inside the movable latch 144 in the retracted state. In the retracted state, the movable latch 144 catches a mating member 146 on the panel 120 to latch a latch catch 148, completing the closing and latching of the panel 120.

The range hood 100 provided by the invention adopts a new scheme of maintaining the opening and closing of the panel 120, and compared with the opening and closing mode of manually pulling the lower edge of the panel 120 in the related art, the range hood adopts a mode of pressing to open and close, so that the phenomenon that a human hand touches an oil stain gathering area on the lower edge of the panel 120 can be avoided, the pressing mode is more in line with the operation habit of the human hand, and the user experience is improved. In particular, the panel 120 is in particular a glass panel 120. When the panel 120 is closed, the pressing force of the hand is fed back by the continuous force because the glass panel 120 is continuously supported by the gas spring 130, and the pressing process is relatively stable. The glass panel 120 is locked by the locking mechanism after the glass panel 120 is closed. And, in a large oil smoke environment, the glass panel 120 can be conveniently turned up to be used as a smoke collecting plate.
