Description
Technical field
The present invention relates to smoke exhaust ventilator technical fields, and in particular to a kind of two-stage is without fan smoke exhaust ventilator.
Background technique
Most of smoke exhaust ventilator sold currently on the market is all positioned against air inlet and is produced by the rotation of blower impeller
Raw suction completes smoke exhaust ventilator work, smoke exhaust ventilator using when the shortcomings that be concentrated mainly on cleaning trouble, suction is insufficient, runs cigarette
Problem, troublesome in poeration, kitchen ventilator volume is big, this big several respect of running noises；Motor driven blade rotates when work, makes kitchen ventilator
Negative pressure is formed in air duct, the oil smoke and air of lower section are entered air duct by vacuum suction, and are finally discharged to outdoor by air duct.At this
During a, oil smoke directly contacts with blade and is adsorbed on blade surface, and long-time service can accumulate a large amount of greases in blade surface,
If cleaning will cause blade rotation bias, and then the mist extractor efficiency of influence smoke exhaust ventilator not in time, but blade is located at wind
In road, it is difficult to disassemble and install, and grease is difficult to clean.
Summary of the invention
In order to overcome the disadvantages of the above prior art, the object of the present invention is to provide a kind of two-stages without fan smoke pumping
Machine not only may be implemented mute and Wind Volume when smoke exhaust ventilator, but also can reduce the size of range hood structure, and realization is opened
Formula design is put, has structure simple, easy to use, pumping efficiency is high, and use is safe, the service life is long, noise is small, oil smoke accumulation is small etc.

It under band and negative pressure collective effect, by the air flow rate of annular interface, is significantly enlarged, reaches air blower 6 itself and extract air quantity
More than ten times；(fluid carry-over principle: when there is a branch of air-flow rapidly to pass through, it can pull the air of surrounding, them is made to follow it
It moves together；Principle of negative pressure: being that air pressure after being travelled forward due to local air, after annulus can reduce, and cause rear more
Air be added with equilibrium air pressure)；When high-speed flow is flowed out from the narrow annular channel 12 of primary air stream amplifier 1, high-speed flow
The mixed gas 13 of the oil smoke and air that will drive front is flowed to secondary air flow amplifier direction, and secondary air flow amplifier 2
Narrow annular channel 12 in the high-speed flow that blows out there is traction and effect of contraction to the air-flow in front of it under negative pressure region effect,
The mixed gas 13 for drawing and constrain the oil smoke and air that are blown by primary air stream amplifier 1 passes through secondary air flow amplifier 2；
Attraction and constraint by air flow amplifier to annulus outside air, operative constraint and have guided primary air stream amplifier 1, second level
Oil smoke between air flow amplifier 2, prevents it from extending out.The design of two-stage air flow amplifier reduces overall dimensions and weight, into one
Step increases air quantity and promotes oil smoke absorption efficiency；After oil smoke is from secondary air flow amplifier 2 into cross-sectional constriction pipeline 7, due to section
It shrinks, fluid velocity is accelerated, and runs through cross-sectional constriction pipeline 7 and wind pipe 5 and outdoor is discharged.
