The present embodiment achieves the object of improving the purification effect thereof by 25-30% in the case of the same size of the purification passage 11. Meanwhile, due to the arrangement of the at least two ionization devices 2, the size of the corresponding adsorption device 3 of the low-pressure area 120 is reduced, the body resistance of an electric field of the low-pressure area 120 is also reduced, and the whole oil smoke is favorably pumped and discharged.
