Abstract: A diaphragm structure includes a vibrator, a first guide inserted into a lower side of the vibrator, a second guide inserted into a lower side of the first guide and having a part configured to protrude from an upper side of the vibrator, and a filtering member configured to filter introduced foreign matter, wherein the first guide and the filtering member are formed as one component integrally formed of a plastic material, and a plurality of filtering holes are formed in a side surface of the vibrator, which is positioned in a protruding direction of the second guide.

Abstract: A valve includes an inlet unit including an inlet hole into which a fluid is introduced, a pressure adjusting unit which adjusts a pressure of the fluid introduced through the inlet unit, and a discharging unit having an opening and closing member which selectively discharges the fluid which had its pressure adjusted, and a water outlet hole which discharges the fluid passing through the opening and closing member to the outside, wherein a cross-sectional area of the inlet hole is greater than a cross-sectional area of the water outlet hole and a flow direction of a fluid from the pressure adjusting unit to the opening and closing member and a flow direction of a fluid from the opening and closing member to the water outlet hole are perpendicular to each other.
