Claims (1)

[Claims for Utility Model Registration] (1) A container comprising a container portion having an inlet port connected to a tank of a device, and a lid portion covering an opening of the container portion and having an outlet port connected to the tank; a filter that has one end surface attached to the lid portion and filters the liquid introduced into the container from the inlet port and sends it to the outlet port; one end surface is attached to the lid portion insulated from the container portion; A single or plural cylindrical electrode into which a filter is inserted, an electrode applying means for applying a voltage to the liquid, which is composed of the electrode and the container part, and between the container part and the electrode or between the electrode and the filter. or a dielectric material made of an adsorbent or an insulator installed at least in one of the electrodes;
A liquid filtration device comprising: a detection device for detecting a resistance value between auxiliary electrodes installed in the container; and a display or alarm device energized by the output of the detection device to notify a contamination limit of the liquid. (2) The delivery port is made of a conductive pipe that is inserted through the lid and has a through hole in the inside of the filter, and the voltage application means is comprised of the delivery port, the container part, and an electrode. The liquid filtration device according to item 1. (3) The liquid filtration device according to claim 1 or 2, wherein the electrodes include first and second cylindrical electrodes arranged concentrically and each having a different potential. (4) The liquid filtration device according to claim 1 or 2, wherein the electrodes include first and second cylindrical electrodes arranged concentrically and having the same potential, respectively. (5) The liquid filtration device according to any one of claims 1 to 4 of the utility model registration claim, wherein the detection device is a relay device that is activated when the resistance value between the auxiliary electrodes becomes equal to or less than a predetermined value.
