Claims

[Scope of utility model registration request]

A stepped through hole having an enlarged diameter portion at the mouth edge on the upper end side is formed in the bottom surface of the bowl, and a flange is provided in the through hole at the upper end portion to tightly fit into the enlarged diameter portion, and An outer cylinder made of a highly elastic material having a mounting part forming a mounting space between the through hole and the lower end is fitted non-rotatably into the outer cylinder, and a blockage is provided at the upper end of the outer cylinder to abut against the collar. An inner cylinder made of a highly rigid material forming a plate and having a drainage passage extending from the outer circumferential surface directly below the closing plate to the lower end surface has a lower end protruding from the outer cylinder so that it can freely move up and down, and a rotary cylinder made of a highly rigid material that is fitted in a non-rotatable manner and whose lower end protrudes below the bowl is attached to the outer periphery of the lower end of the outer cylinder so that only rotation is possible;
A female thread formed on the inner peripheral surface of the rotating cylinder is screwed into a male thread formed on the outer peripheral surface of the lower end of the inner cylinder, and the rotating cylinder is rotated in one direction to move the inner cylinder toward the rotating cylinder. A seal is created between the closing plate and the collar by pulling and pressing the closing plate against the collar;
By rotating the rotary cylinder in the other direction and pushing up the inner cylinder, a gap is formed between the blocking plate and the collar, and the water in the bowl is drained to the outside through the drainage passage. Features: Air filter drainage device.
