Embodiment
The present invention is described in further detail below in conjunction with attached 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 movable oil cleaner screen above outer layer oil cleaner screen 2, changes oil network gap by moving up and down for internal layer oil cleaner screen 3.
In order to make internal layer oil cleaner screen 3 to 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
It is inserted into corresponding 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, the installation 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 cavity 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
Inner cavity and lower inner cavity.
Wherein, the upper inner cavity of main piston cylinder 41 is pressure chamber, and venthole 46 is provided with the pressure chamber, on venthole 46
The snorkel 5 that can be connected with range hood outlet or flue is installed, in this way, the outlet back pressure of range hood can be anti-in time
It is fed in the pressure chamber of main piston cylinder 41.
The lower inner cavity of main piston cylinder 41 and the lower inner cavity of driving piston cylinder 42 are interconnected by connecting hole 47, also,
Injection gas or hydraulic oil in the lower inner cavity of main piston cylinder 41 and the lower inner cavity of driving piston cylinder 42.Set on driving piston 44
Drive rod 45, driving piston 44 are structure as a whole with drive rod 45, and drive rod 45 sets up and is connected to internal layer oil cleaner screen 3
On.In this way, when the outlet back pressure increase of range hood, the pressure acted on main piston 43 also accordingly increases, so that
The increase of 43 lower flow pressure of main piston, according to pascal's principle, the pressure that driving piston 44 is subject to also accordingly increases, so that band
Dynamic drive rod 45 moves up, and internal layer oil cleaner screen 3 also syncs up movement, so make internal layer oil cleaner screen 3 and outer layer oil cleaner screen 2 it
Between gap increase, the system resistance of range hood reduces, and increases air quantity, beneficial to effective suction oil smoke, to overcome range hood
The adverse effect of outlet back pressure increase.On the contrary, when outlet back pressure becomes small, between internal layer oil cleaner screen 3 and outer layer oil cleaner screen 2
Gap diminishes, and at this time, although system resistance is larger, air quantity diminishes, and can reduce noise.
In addition, can only be moved up and down to limit drive rod 45, mounting hole is provided with the bottom of internal layer oil cleaner screen 3
32, drive rod 45 is upward through mounting hole 32 and is fixed on internal layer oil cleaner screen 3, also, is provided with the head of drive rod 45
Perforate baffle ring 6, by the spacing of perforate baffle ring 6, drive rod 45 can only move up and down.
During design, the ratio of the sectional area and driving 42 sectional area of piston cylinder of appropriately designed main piston cylinder 41, can obtain
Compare appropriate driving force to promote internal layer oil cleaner screen 3 to move up and down, dynamically to change internal layer oil cleaner screen 3 and outer layer oil cleaner screen
Gap between 2, and then change the system resistance coefficient of range hood, system resistance system is carried out certainly according to outlet back pressure
Adapt to adjustment.
The foregoing is merely the preferred embodiment of the present invention, it is noted that for those of ordinary skills,
Under the premise of the principle of the present invention is not departed from, a variety of remodeling or improvement can be carried out to the present invention, these are regarded as the present invention
Protection domain within.
