The wind inlet channel of the side smoking machine of this programme adopts forward and backward pair of wind inlet channel, and the impeller of blower fan is double air intake
Impeller, after oil smoke enters in body fuselage, a part of oil smoke sequentially passes through cover body advance air port, diversion air duct and spiral case and advances
Air port is inhaled into volute of blower, enters inside double intake air impellers, the exhaust outlet eventually passing volute of blower is discharged to outside body；
Another part oil smoke sequentially passes through cover body rear air inlet, diversion air duct and spiral case rear air inlet and is inhaled into volute of blower, enters double
Inside intake air impeller, the exhaust outlet finally also passing through volute of blower is discharged to outside body；Thus effectively increasing the wind of smoking machine
Amount, the effect of reinforcement fume exhaust, and reduce noise.On the other hand, motor is located in diversion air duct, can effectively reduce motor
Temperature rise, thus the service life of lifting motor.
Preferably, being provided with mid-game in double intake air impellers, the rotating shaft of described motor is connected with mid-game, and described pair is entered fan blade
Axial spacing between one end of wheel and mid-game is more than or less than the axial spacing between the other end of double intake air impellers and mid-game.
Mid-game in current double intake air impellers is generally using being symmetrical arranged；And this programme is on the contrary, mid-game is using non-
It is symmetrical arranged（I.e. the axial spacing between one end of double intake air impellers and mid-game be more than or less than the other end of double intake air impellers with
Axial spacing between mid-game）, through test, because the asymmetric setting of this impeller central disc is so that the performance of cigarette machine has significantly
Lifting, air quantity increases, and about lower noise 1.5dB (A), and the effect of fume exhaust is also accordingly strengthened.
Preferably, the middle part of mid-game is provided with the mid-game axle sleeve with the output shaft cooperation of motor, the rotating shaft of described motor is worn
Cross mid-game axle sleeve, the rotating shaft of motor is provided with threaded locking nut, and locking nut is located at mid-game axle sleeve with motor
Opposite sides.
Preferably, mid-game is provided with some air vents.
Preferably, motor is located in cover body rear air inlet or cover body advance air port.
Preferably, motor is bolted on volute of blower.
The invention has the beneficial effects as follows：Can not only increase smoking machine air quantity, strengthen fume exhaust effect, but also
The service life of motor can be improved.
