Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 7, the range hood of the present embodiment is top-sucking kitchen ventilator, specifically includes exhaust fume collecting hood 1, outer
Layer oil cleaner screen 2 and internal layer oil cleaner screen 3, wherein, outer layer oil cleaner screen 2 is the fixation oil cleaner screen being fixed on exhaust fume collecting hood 1, internal layer oil strain
Net 3 is the movable oil cleaner screen above outer layer oil cleaner screen 2, passes through moving up and down to change oil network gap for internal layer oil cleaner screen 3.
In order that internal layer oil cleaner screen 3 can only move up and down, in the present embodiment, at least three are provided with the bottom of outer layer oil cleaner screen 2
Root lead 21, lead 21 are set straight up, and the bottom of internal layer oil cleaner screen 3 is provided with corresponding pilot hole 31, lead 21
Corresponding to insertion in pilot hole 31.
Telescoping cylinder 4 and lubricating cup 7 are installed in the bottom center of outer layer oil cleaner screen 2, wherein, telescoping cylinder 4 abuts in outer layer filter
The bottom of oil network 2 is simultaneously hidden in inside lubricating cup 7.
The telescoping cylinder 4 of the present embodiment includes main piston cylinder 41 and driving piston cylinder 42.Wherein, installed in main piston cylinder 41
Have annular and horizontally disposed main piston 43, main piston 43 cavity of main piston cylinder 41 is divided into upper inner chamber and lower inner cavity,
Horizontally disposed driving piston 44 is installed, the cavity for driving piston cylinder 42 is divided into by driving piston 44 in driving piston cylinder 42
Upper inner chamber and lower inner cavity.
Wherein, the upper inner chamber of main piston cylinder 41 is pressure chamber, and passage 46 is provided with the pressure chamber, in passage 46
On be provided with and can be exported with range hood or the breather pipe 5 that be connected of flue, so, the outlet back pressure of range hood can be timely
Feed back in the pressure chamber of main piston cylinder 41.
The lower inner cavity of the lower inner cavity of main piston cylinder 41 and driving piston cylinder 42 is interconnected by connecting hole 47, also,
