ELECTRODE CONTAMINATION REMOVAL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an electrode contamination removal structure that can sufficiently remove contamination of a surface of an electrode without using an electronic circuit.SOLUTION: An electrode contamination removal structure comprises: a first electrode 32; a second electrode 37 opposing the first electrode 32; a coupling bar 33 that is rotatably provided between the first electrode 32 and the second electrode 37; a first contamination removal member 34 that comes into contact with the first electrode 32 and is provided at one end of the coupling bar 33 so as to remove contamination at a prescribed part of the first electrode 32 when the coupling bar 33 rotates; a second contamination removal member 39 that comes into contact with the second electrode 37 and is provided at the other end of the coupling bar 33 so as to remove contamination at a prescribed part of the second electrode 37 when the coupling bar 33 rotates; an electrode reception container 30 in which the first and second electrode 32 and 37, and the coupling bar 33 are received; and a weight 35 that is provided in the coupling bar 33 for rotating the coupling bar 33 due to an impact when the electrode reception container 30 falls to a liquid.SELECTED DRAWING: Figure 2
