Compared with prior art, the invention has the advantages that the motor and the fan blade that have saved in traditional lampblack absorber air duct, it is very convenient to clean oil smoke, owing to adopted Air pressurizer, compare with traditional lampblack absorber that noise is lower, security is better, characteristics such as oil suction cigarette efficient height.
The air that Air pressurizer will enter in the blast pipe carries out supercharging, by first annular chamber in the guide duct tube wall, blows to the oil extraction smoke pipe from annular air guide hole then.
Air is full of in first annular chamber of guide duct, accumulate to a certain degree and will surpass the outer normal barometric pressure of cavity, so formation wind, because very tiny of annular air guide hole, force the air motion of first annular chamber, constantly the air of mutual extrusion can only be gone out from tiny annular air guide hole " leakage " at last, and continuous service is after a period of time, air pressure in first annular chamber is constantly strengthened, and makes the air-flow of annular air guide hole quicker.In case the air-flow of annular air guide hole is accelerated, form the blowing effect, will cause that the interior air of oil extraction smoke pipe is also with flowing.Air produces negative pressure in the oil smoke cover, and the air of oil smoke cover below can constantly be replenished into, strengthens the air-supply effect.The stack of multichannel air-flow will form and be several times as much as the air-supply effect that blast pipe absorbs the air ability.
Airstrainer filters the air that enters before the Air pressurizer.
Oil smoke in the oil extraction smoke pipe is delivered in the oil smoke passage, and the oil smoke in the oil smoke passage can flow in second annular chamber, because second annular chamber lower end closed and the inclination, Residual oil can drop in the oil bottle by the oil leaking hole of least significant end.
The valving that can open automatically or close, when range hood is worked, valve opening, the oil smoke in the oil extraction smoke pipe can be delivered in the oil smoke passage, behind the valve closing, other indoor oil smoke just can't by the oil extraction smoke pipe enter into be equipped with of the present utility model indoor.
First sealing gasket and second sealing gasket cooperatively interact, and can make the better tightness of valve.
Under first coil, second coil and tertiary coil "on" position, the upper end of the 3rd iron core is N polarity, the free end of second iron core is N polarity, first iron core one end close with the second iron core free end is S polarity, second iron core and first iron core attract each other, second iron core and the 3rd iron core repel mutually, under the effect of two external force, make valve be in open mode.Under coil no power state, valve is closed under the gravity effect.
Protective jacket can prevent the corrosion to iron core and coil of oil smoke, water.
