Abstract: Disclosed is a filter assembly including a filter module, and a pocket module configured to accommodate therein the filter module, in which the pocket module includes a pocket body region having an accommodation space S, and a pocket fixing region provided at one side of the pocket body region, in which the filter module includes a filter body region configured to be accommodated in the accommodation space S, and a filter concave-convex region provided on an outer peripheral surface of one side of the filter body region and configured to be coupled to the pocket fixing region, and in which the pocket fixing region includes a button member configured to be movable in a first width direction W1, a plate member configured to be movable by the button member in a direction intersecting the outward longitudinal direction A1 and having a hole H configured to connect the accommodation space S and the outside, and a spring member configured to press the plate member.

Abstract: Disclosed is a filter assembly including a filter module, and a pocket module configured to accommodate therein the filter module, in which the pocket module includes a pocket body region having an accommodation space S configured to communicate with the outside, in which the filter module includes a filter body region configured to be accommodated in the accommodation space S, inlet and outlet regions formed on an outer surface of the filter body region based on an inward longitudinal direction A2 that is a direction opposite to an outward longitudinal direction A1, and in which the inlet region and the outlet region are provided to be spaced apart from each other in a radial direction R of the filter module.

Abstract: According to the present invention, an electrode terminal assembly for a liquid quality meter apparatus for measuring liquid quality on the basis of the electrical resistance of a liquid to be measured comprises: a pair of electrode terminals comprising a body, which contacts the liquid being measured when liquid quality is measured and has an overall rod shape, and a protruding step formed at a predetermined portion between the opposite ends of the body; and a fixing body comprising a pair of electrode through-holes through which the pair of electrode terminals pass. In the electrode terminal assembly having the above-described structure, each of the pair of electrode terminals is arranged such that, when the electrode terminals are inserted into the electrode through-holes of the fixing body by a predetermined length, the protruding step is caught by the fixing body so that the electrode terminals are no longer inserted.

Abstract: The present disclosure relates to a mouse on a chopsticks style used as an input device of a computer.
