Problems solved by technology

[0011] In addition, since the prior art described in Patent Documents 1, 2, and 3 cannot be applied to an ion generator in which the air flow does not flow, it is necessary to select a removal method other than blowing off foreign matter with air.
[0012] In addition, in the prior art described in Patent Documents 2 and 3, since the electrodes are not pointed, there is also a problem that the discharge characteristics are inferior to those of the needle-shaped electrodes.

Embodiment Construction

[0055] Next, the best mode for implementing the present invention will be described based on the drawings. figure 1 It is an explanatory drawing of the discharge electrode and the discharge electrode unit of this form, figure 1 (a) is an enlarged view of the tip of the discharge electrode, figure 1 (b) is a structural diagram of the discharge electrode unit, figure 1 (c) is an explanatory diagram of the operation of the discharge electrode unit. Such as figure 1 As shown in (a), the discharge electrode 1 has the needle electrode 1a and the slider 1b.

[0056] The acicular electrode 1 a is formed of a conductor, and is an acicular body with a tip portion formed as a tip.

[0057] The slider 1b is formed as a cylindrical body, and has a front end portion 1c, an opening portion 1d, and a hole portion 1e. The front end portion 1c is formed in an annular shape. The opening 1d is formed on both sides of the hole 1e, and the opening 1d and the hole 1e are formed to have the sam...

Abstract

The present invention provides a discharge electrode for corona discharge and a discharge electrode unit, which can easily remove foreign matter even when the foreign matter is firmly adhered to the top of the front end and can realize sustaining of excellent discharge characteristic for a long time. The discharge electrode (1) is composed to posses a needle-shaped electrode (1a) and a sliding member (1b). The needle-shaped electrode (1a) is composed of a conductor. The sliding member (1b) is provided with a hole part (1e) which is inserted into the needle-shaped electrode (1a) through clearance matching. Additionally, a discharge electrode unit (100) is composed to movably support the discharge electrode (1) of the invention.

Description

technical field [0001] The present invention relates to a discharge electrode for corona discharge and a discharge electrode unit supporting the discharge electrode. Background technique [0002] As a prior art of a discharge electrode for corona discharge, for example, the invention described in Patent Document 1 (Japanese Patent Laid-Open No. 2007-134141 Invention Title: Electrode Needle Unit of Ionization Device and Ionization Device) is known. [0003] In the prior art described in Patent Document 1, the electrode needle is supported by a support member at a part of the side closer to the base of the electrode needle, and air is made to flow around the tip of the electrode needle. As a result, the dust, foreign matter, etc. located near the tip of the electrode needle are blown away by the air, so that the dust, foreign matter, etc. do not adhere. [0004] In addition, as another prior art, for example, the invention described in Patent Document 2 (Japanese Patent Laid-...
