Blower fan system 2 is connected with body 1 and is suitable for generating air-flow, and oil-collecting petticoat pipe 3 is connected with body 1, and oil-collecting petticoat pipe 3 limits
The air duct 34 being connected to out with blower fan system 2, oil-collecting petticoat pipe 3 include inner cover 31 and outer cover 32 arranged spaced apart, inner cover 31 and outer
Auxiliary air duct 33 is limited between cover 32, outer cover 32 is equipped with the air inlet 321 be connected with auxiliary air duct 33, inner cover 31 and outer cover
32 bottom interval offers the air outlet 331 be connected with air duct 34；Accessory fan is located in auxiliary air duct 33 to generate air-flow.
In other words, 2 sum aggregate oil smoke cover 3 of blower fan system is connected with body 1 respectively, and oil-collecting petticoat pipe 3 is located at the lower section of body 1,
Exhaust passage 34 is limited in oil-collecting petticoat pipe 3, blower fan system 2 is rotated to generate air stream, and blower fan system 2 is connected to air duct 34, blower
Oil smoke is drawn by oil-collecting petticoat pipe 3 when system 2 works, the oil smoke of cooking stove flows towards 3 direction of oil-collecting petticoat pipe and passes through air duct 34
Blower fan system 2 is flowed to, indoor oil smoke is sucked out by blower fan system 2 and is expelled to outdoor.
As Figure 1-Figure 4, oil-collecting petticoat pipe 3 may include inner cover 31 and outer cover 32, limit between inner cover 31 and outer cover 32
Air duct 33 is assisted out, and accessory fan is located in auxiliary air duct 33, and outer cover 32 is equipped with air inlet 321, air inlet 321 and auxiliary wind
Road 33 is connected to, and can be spaced apart between the bottom of inner cover 31 and the bottom of outer cover 32 to form air outlet 331, air outlet 331 is distinguished
It is connected to auxiliary air duct 33 and air duct 34.In this way, the effect in accessory fan can produce secondary air, specifically, secondary air
From the flow direction auxiliary of air inlet 321 air duct 33 on outer cover 32, and air outlet 331 is oriented to by auxiliary air duct 33, finally from outlet air
Mouth 331 is blown out, and drives the stream for flowing to the air stream that oil-collecting petticoat pipe 3 is surrounded when secondary air is blown out from air outlet 331
It is dynamic, negative pressure is formed in the space surrounded with the inner cover 31 in oil-collecting petticoat pipe 3, and then can promote oil when oil-collecting petticoat pipe 3 works
The flowing of cigarette, to achieve the purpose that smoke exhaust ventilator 100 to the powerful absorption of oil smoke, improves the smoke absorption effect of smoke exhaust ventilator 100.
Smoke exhaust ventilator 100 according to an embodiment of the present invention, oil-collecting petticoat pipe 3 include inner cover 31 and outer cover arranged spaced apart
32, auxiliary air duct 33 is limited between inner cover 31 and outer cover 32, outer cover 32 is equipped with the air inlet be connected with auxiliary air duct 33
321, the bottom interval of inner cover 31 and outer cover 32 offers the air outlet 331 be connected with air duct 34, and accessory fan is located at auxiliary wind
In road 33.To generate air-flow, air-flow is blown out by air outlet 331 for accessory fan work, flows to 3 institute of oil-collecting petticoat pipe so as to drive
The flowing of the air stream of encirclement is formed negative pressure in the space surrounded with the inner cover 31 in oil-collecting petticoat pipe 3, and then can promote oil-collecting
The flowing of oil smoke when petticoat pipe 3 works, to achieve the purpose that smoke exhaust ventilator 100 to the powerful absorption of oil smoke, improves smoke exhaust ventilator 100
Smoke absorption effect.
In some embodiments of the invention, what oil-collecting petticoat pipe 3 was formed as that Open Side Down is tubaeform.In other words, oil-collecting
The opening of petticoat pipe 3 is in tendencies toward shrinkage on direction from the bottom to top, and the lower ending opening of oil-collecting petticoat pipe 3 is towards cooking stove, in blower system
Under the action of system 2, the oil smoke that cooking stove generates can flow to the opening of oil-collecting petticoat pipe 3, and flow along the air duct of oil-collecting petticoat pipe 3 34, lead to
Tubaeform oil-collecting petticoat pipe 3 is crossed so as to preferably absorb and collect flue gas.In conjunction with shown in Fig. 1 and Fig. 4, oil-collecting petticoat pipe 3 it is interior

It separates and cooperates to form air outlet 331, air-flow can flow when flowing out from air outlet 331 along the inner wall of inner cover 31, so as to band
The flowing for the oil smoke that dynamic inner cover 31 is surrounded.
Advantageously, the angle between the tangential direction and horizontal plane of air outlet 331 can be φ, 0 ° < φ≤90 °.Also
It is to say, the tangential direction of air outlet 331 tilts relative to horizontal direction.Along air outlet 331 when air-flow is blown out from air outlet 331
Tangential direction outflow, the flowing for the oil smoke that inner cover 31 can be driven to be surrounded when air-flow is flowed out from air outlet 331 as a result, and can band
Dynamic oil smoke is flowed towards air duct 34, to enhance the smoking wind strength of smoke exhaust ventilator 100.Preferably, 30 °≤φ≤60 °
Optionally, the oil storage box 4 along its circumferentially extending can be equipped in oil-collecting petticoat pipe 3, oil storage box 4 will assist air duct 33 to separate
At upper chamber 332 and lower chamber 333, accessory fan is located in lower chamber 333, and air inlet 321 and air outlet 331 are under
Portion's chamber 333 is connected, and inner cover 31 is equipped with multiple oil filter holes 311 be connected with upper chamber 332.Accessory fan works as a result,
To generate air-flow, air-flow flows to lower chamber 333 from air inlet 321, and flows to air outlet 331, air-flow by lower chamber 333
It blows out from air outlet 331 so as to the flowing for the air for driving inner cover 31 to be surrounded, with the wind of the fume-exhausting of enhancing collection kitchen ventilator
Power, under the action of blower fan system 2, oil smoke flows to upper chamber 332 by the oil filter hole 311 on inner cover 31, and passes through top
Chamber 332 flows to the exhaust air flue 34 of smoke exhaust ventilator 100, and is expelled to outdoor by exhaust air flue 34.It can by oil filter hole 311
Realize to the separating and filtering to oil smoke, it is filtered it is dirty flowed in oil storage box 4 by center of gravity effect, thus may make pot and stove and
Food therefore neat and tidy without contaminated.
Further, oil storage box 4 is detachably arranged between air inlet 321 and oil filter hole 311, need oil storage box 4 into
When row cleaning, to facilitate the disassembly and installation of oil storage box 4.The section of oil storage box 4 is formed as S-shaped, the upper end of oil storage box 4 with
Outer cover 32 is connected, and the lower end of oil storage box 4 is connected with inner cover 31, wherein the upper opening of the S-shaped of oil storage box 4 is towards 32 side of outer cover
To and with air inlet 321 it is corresponding, the lower openings of the S-shaped of oil storage box 4 towards 31 direction of inner cover and the lower part of oil storage box 4 with it is interior
Cover 31 is connected, and is spaced apart between upper chamber 332 and lower chamber 333 by S-shaped oil storage box 4 as a result, and air inlet 321 is under
Portion's chamber 333 is connected to, and the filtered greasy dirt of oil filter hole 311 of inner cover 31 can flow to oil storage box 4 along the outside wall surface of inner cover 31.
