The water saving siphon cover 100 comprises a flexible air chamber 10 and a rigid air housing 20 connected to the lower side of the air chamber 10 to form an air room 30 inside. The air chamber 10 comprises a supporting portion 11, a variable portion 12 having a horizontal portion 12a and a sloping portion 12b, a ceiling portion 13 closing the upper side of the variable portion 12, an outer flange 15, and a pair of hinge portions 17, each being extended from one side of the outer flange 15. The cup shaped air housing 20 comprises a suction hole 22 and an air vent 23. The water saving siphon cover 100 is installed such that the end of the hinge portion 17 blocks an outlet port 36 in a water tank 37, being hinged to the overflow tube 31. Thus, the water saving siphon cover 100 can save water according to the required amount of wash water based on a change in the opening time of the outlet port 36 caused by a difference between the buoyant force for flushing urine and the buoyant force for flushing feces.

1. A water saving siphon cover, comprising: a flexible air chamber provided with a supporting portion which is thick and forms a wall body in the sloping shape that provides a smaller diameter as it goes upwardly, a variable portion having a horizontal portion and a sloping portion and being extended at a small thickness in the shape of being contracted in a stepwise manner upwardly from the peripheral surface of the upper side of the supporting portion, a ceiling portion with a maxi-flush loop at the center of the upper surface which blocks the upper side of the variable portion with a large thickness such that it can change the internal volume as the height is changed up and down according to a change of the variable portion caused by an external force, an outer flange which is formed widely outwardly along the peripheral surface of the lower end portion of the supporting portion and has a coupling recess formed convexly along the inner periphery and a mini-flush loop formed at one side of the upper surface, and a pair of hinge portions, each being extended from one side of the outer flange and each end being hinged to the protrusion of the overflow tube; and a rigid air housing formed in a cup shape that is protruded downwardly such that the inside can form an air room along with the inside of the air chamber, said air housing having a coupling flange extended widely outwardly along the peripheral surface of the upper end portion completely open so that it can be coupled to the coupling recess of the air chamber, a suction hole penetrated through the center of the bottom and an air vent penetrated through one side of the upper portion thereof. 2. The water saving siphon cover of claim 1, wherein the air housing is formed with a thickness of 2 mm, being extended by 7.50 mm vertically from the periphery of a hemisphere with a radius of 20.03 mm, the coupling flange with a thickness of 1.2 mm is formed in the shape of being extended from the end of the air housing, the suction hole is formed in the shape of a circle with a diameter of 60 mm, and the air vent is preferably formed adhesively to the lower side of the coupling flange in the shape that provides a hemisphere having 2 mm diameter that is cut farther from below a rectangle with 4 mm width and 4.32 mm height. 3. The water saving siphon cover of claim 1, wherein the supporting portion is formed with 1.0 mm thickness having 57.692 mm outer diameter of the lower side and 53.163 mm outer diameter of the upper side, the variable portion is formed with a thickness of 0.7 mm and the sloping portion is curved upwardly from the boundary at an outer diameter of 44.169 mm of the horizontal portion, the ceiling portion is bordered on the sloping portion 12b at an outer diameter of 34.389 mm, in which the inner, lower surface is flat and the outer, upper surface is formed convexly with a shape of a curved surface having a radius of 48.562 mm., and the coupling recess is preferably formed at a position spaced 3 to 45 mm downwardly from the lower portion of the supporting portion. 4. The water saving siphon cover of claim 1, wherein a plurality of flow adjust scales are arranged and sequentially carved with the same intervals at an angle of 90 to 180 degrees from the overflow tube on either one of the upper and lower surfaces of the coupling flange of the air chamber.
