Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model.
First embodiment
Referring to Fig. 1-Fig. 3, this smoke exhaust ventilator includes casing 1, air compressor 2 and air amplifier 3, is set in casing 1
Cigarette component is led, air amplifier 3, which is fixed on, is led in cigarette component, and interconnected discharge flue a is provided with air amplifier 3
With air nozzle b, the outlet air end of air compressor 2 connects discharge flue a by air nozzle b；Discharge flue a air intake connects
The air intake of admittance cigarette component, outlet air end connect the outlet air end for leading cigarette component.The air that this structure can export air compressor 2
Entered by air amplifier 3 and led in cigarette component, the compressed air of flowing quickly flows away from leading in cigarette component, makes the top of cooking stove 8
Negative pressure is formed, so as to which oil smoke be taken away；Due to eliminating motor and wind wheel in traditional structure, discharge flue a and sky are substituted for
Gas jets b, therefore noise and vibrations can be effectively reduced, and also air quantity is bigger, and it is more efficient, it is easier to clean.
Furtherly, air amplifier 3 is provided with the air duct 4.1 of annular, and the outlet air end connection of air compressor 2 is empty
Gas passage 4.1, air duct 4.1 connect discharge flue a by air nozzle b, and air nozzle b is that discharge flue a leads to air
Annular gap between road 4.1, compressed air enter discharge flue a in a manner of spraying.
Furtherly, air amplifier 3 includes upper amplification housing 4 and lower amplification housing 5, is put in lower amplification housing 5 insertion
The big bottom of housing 4, and it is mutual in lead to structure and be collectively forming described discharge flue a, discharge flue a and air duct 4.1 it
Between be spaced from each other by sleeve 4.2, have spacing between the end of sleeve 4.2 and lower amplification housing 5 end face, form the air spray
Mouth b.
Furtherly, air amplifier 3 is provided with compressed air interface 4.3, and the compressed air interface 4.3 connection air leads to
Road 4.1, compressed air interface 4.3 can facilitate connection pipe body c realizations to be connected with air compressor.
Furtherly, air duct 4.1, sleeve 4.2 and compressed air interface 4.3 are added by the upper one of amplification housing 4 respectively
Work is molded.
Furtherly, leading cigarette component includes the smoke guiding cover 6 of interconnection and leads smoke pipe 7, and smoke guiding cover 6, which is plugged in, leads smoke pipe 7
On, air amplifier 3 is fixed on smoke guiding cover 6.
Furtherly, air compressor 2 is arranged in casing 1, makes the connection of air compressor 2 and air amplifier 3 more
Convenient, complete machine is more attractive.
Concrete operating principle：
Referring to Fig. 1 and Fig. 2 (solid arrow is compressed air in figure, and center line arrow is oil smoke), air compressor 2 is powered
Work, its caused compressed air is through delivering into annular air duct 4.1, then by the air nozzle b high speeds of annular
Injection forms high velocity air, and this burst of primary airstream absorption is leading entering for cigarette component on the surface of the upper amplification inner surface contour of housing 4
Wind end (top of cooking stove 8) forms negative pressuren zone, thus the substantial amounts of air (oil smoke) of surrounding can be inhaled into, primary airstream and surrounding flow
Formation high speed, the air-flow of high power capacity are flowed out from air amplifier 3 after converging, and high velocity air is driven by " Coanda effect " and leads cigarette
The outlet air end of air guide cigarette component in component gushes at a high speed；According to hydromechanical general principle (wall attachment effect Coada
Effects), it is only necessary to by the use of a small amount of compressed air as power source, drive surrounding air to flow to form high pressure and high velocity air, flow
Amount can reach 50 times of air consumption.
Second embodiment
Referring to Fig. 4, this smoke exhaust ventilator is different from being in place of first embodiment：Air nozzle b is discharge flue a and air
More than one through hole between passage 4.1；Specifically, above breach 4.4 at one, upper amplification is distributed with the end annular of sleeve 4.2
When housing 4 assembles with lower amplification housing 5, the open side of the end face closing breach 4.4 of lower amplification housing 5 is empty so as to form connection
The through hole of gas passage 4.1 and discharge flue a, its area is smaller, can project compressed air and realize lampblack-pumped function.
Other not described same first embodiments in part, here no longer analytic explanation.
3rd embodiment
Referring to Fig. 5, this smoke exhaust ventilator is different from being in place of first embodiment：The external of air compressor 2 is set, and it sets
It is placed in the lower section of cooking stove 8；The outlet air end of air compressor 2 connects the air nozzle b on air amplifier 3 by body c.This implementation
Example can effectively reduce because of noise and vibrations caused by air compressor 2, and overall weight mitigate significantly, installation more
It is convenient, because air compressor 2 is no longer arranged on casing, so high-tension electricity is not present in casing, it effectively prevent contact accident
Generation.
Air compressor 2 can also be arranged on cooking stove 8 in addition to the lower section of cooking stove 8 is arranged at, or even farther position, with
Adapt to different use environment and use demand.
Other not described same first embodiments in part, here no longer analytic explanation.
