Wherein, the inner cavity of the air guide sleeve 31 is a negative pressure cavity, and a voltage difference is formed between the electrode wire 32 and the dust collecting plate 33.
Under the action of the negative pressure cavity of the pod 31 of the electrical purification apparatus 3 of the present embodiment, the airflow to be purified rapidly enters the inner cavity of the pod 31 from the air inlet 311 of the pod 31, because the air inlet 311 of the pod 31 is provided with the electrode wire 32, the electrode wire 32 ionizes the airflow to be purified, so that the particles 21 in the airflow to be purified are charged to become the charged particles 22, the charged particles 22 move to the dust collecting plate 33 located at the air outlet 312 of the pod 31 at a driving speed under the action of the electric field, and because a voltage difference is formed between the electrode wire 32 and the dust collecting plate 33, the charged particles 22 are attached to the dust collecting plate 33.
