2. Description of the Related Art As one of air purifiers for removing smoke and offensive odor from tobacco generated in offices, restaurants, amusement facilities, etc., an apparatus using an electric dust collector is disclosed, for example, in Japanese Utility Model Registration No. 3033859. In the configuration described in this publication, when the surface of the electrode plate is contaminated by the cleaning operation,
The electrode plate is removed from equipment such as an air purifier, and washed with a special detergent.

However, the electrode plate is relatively heavy, and when the device is mounted on, for example, a ceiling in a room, there is a problem that the attaching and detaching operation is extremely difficult and expensive.

Accordingly, the present applicant has invented a discharge electrode for an air purifier in which the cost is reduced, the weight of the electrode is reduced, and the running cost is reduced, and Japanese Patent Application No. 2000-290248.

[0006] This is because, when a high DC voltage is applied to the dust collecting electrode and the discharge electrode, an attractive force is generated between the dust collecting electrode and the discharge electrode due to an electrostatic force, and movement occurs in a gap portion of the slit, thereby causing a discharge. The characteristics become unstable and affect the dust collection efficiency.
