As shown in fig. 1, the present utility model provides an ionizer 10 including an emitter electrode 11, a receiving electrode 12, a holder 13, and a discharge end 111 provided on the emitter electrode 11. The emitter 11 and the receiving electrode 12 are both long, and both ends of the emitter 11 and the receiving electrode 12 are respectively connected with the fixing frame 13.

The number of the receiving poles 12 is a plurality, and one emitter electrode 11 is arranged between two adjacent receiving poles 12, namely, the receiving poles 12 and the emitter electrodes 11 are alternately arranged. A certain interval exists between the emitter 11 and the receiving electrode 12, the emitter 11 is parallel to the receiving electrode 12, and the emitter 11 and the receiving electrode 12 are respectively perpendicular to the fixing frame 13. Specifically, in the present embodiment, the number of emitters 11 is 2, and the number of receiving poles 12 is 3.

In this way, the emitter 11, the receiving electrode 12 and the fixing frame 13 together form an ionization plane 14, the lengths of the emitter 11 and the receiving electrode 12 are equal, and the ionization plane 14 is rectangular. In the present embodiment, two opposite receiving poles 12 located at the outer side constitute two long sides of the ionization plane 14, and two opposite fixing frames 13 constitute two short sides of the ionization plane 14. In some cases, the two opposite receiving poles 12 located on the outside may also constitute the two short sides of the ionization plane 14, and the two opposite fixing frames 13 constitute the two long sides of the ionization plane 14.

In the utility model, the emitter 11 is connected with negative high voltage, and the receiving electrode 12 is grounded, so as to generate a continuous ionization field. The discharge ends 111 provided on the emitter 11 form corona discharge, releasing a large amount of negative ions from the tip. When air flows through the ionizer 10, pollutants such as particles and dust therein are combined with negative ions, and negative charges are loaded, so that the air is purified. Meanwhile, the released negative ions can also improve the immunity of the human body, improve the blood circulation and the like, and have positive effects on the human body.

Referring to fig. 2, the emitter 11 is provided with a plurality of discharge ends 111, and the discharge ends 111 are uniformly distributed along the emitter 11.

The ionizer 10 is fixed inside the duct case 20 by the fixing frame 13, and the ionizer 10 is disposed at one end near the air outlet 26. The air circulation rate is greatly increased by the arrangement outside the ionizer 10, so that the purification efficiency is improved; meanwhile, the negative ions are easier to diffuse into the air and are absorbed by human bodies.

The ionization control unit 30 is fixed to the outside of the duct lower case 22, and includes an ionization control box 31 and an ionization control wire 32 for controlling the ionizer 10.

Air flows into the air duct case 20 through the air inlet 25, and the contaminant particles therein are combined with negative ions and charged with negative charges while flowing through the ionizer 10.
