The connecting pipe of the fresh wind port connection.
Preferably, the first check-valve and the second check-valve are motorized non-return valve.
The utility model has the beneficial effects that：
A kind of fume-exhausting system of the utility model, when range hood is opened, the first check-valve in first pipe is opened
It opens, indoor oil smoke is extracted through smoke exhaust fan, and oil smoke enters first pipe through oil smoke mouth, and is expelled to outdoor from smokejack；
Meanwhile the second check-valve in second pipe is opened, air delivery duct provides fresh air, and enters suction by second pipe and fresh wind port
Negative pressuren zone on the downside of kitchen ventilator is expelled to smokejack through oil smoke mouth jointly with oil smoke mixing again, forms a stable air draft and mends
Wind circuit, so as to avoid indoor negative pressure state；And since fresh air can enter smokejack through induction, so as to reduce smoke evacuation
The power of wind turbine, reaches energy-saving effect, to reduce the energy consumption of system.Specifically, in winter under operating mode, the cigarette in first pipe
Gas can carry out heat exchange, fresh air obtains partial heat and brings interior into, so as to avoid Interior Space with the fresh air in second pipe
Gas is discharged and the cold and hot amount taken away, has recycled system thermal indirectly, has further decreased air conditioning energy consumption.
