Claims

[Scope of Claim for Utility Model Registration] A cylindrical outer casing in which a water inlet and an outlet are opened diametrically opposite each other, a cylindrical large-diameter portion, and a cylindrical large-diameter portion connected to one end of the large-diameter portion. The outer circumferential surface of the large diameter section is fixed to the inner circumferential surface of the outer casing, and the small diameter section is fixed to the inner circumferential surface of the outer casing. An internal casing inserted into the inner casing, a male screw formed on the outer circumferential surface of a small diameter portion of the inner casing, and a cylindrical valve body, the inner hole of which is fitted over the small diameter portion and inserted into the outer casing. A female screw is provided on the inner circumferential surface of the inner hole and engages with the male screw, and when rotated in the normal direction around the axis, the tip surface touches the radial wall of the inner casing. When the valve body takes the abutting position and is reversed, the distal end face takes a position away from the radial wall, and the rear end of the valve body protrudes outward from the end of the outer casing, and the rear end of the valve body protrudes outward from the end of the outer casing. The valve body is provided with a groove-shaped waterway that guides water from the inflow port to the outflow port, and is detachably attached to the large diameter portion, and defines a space for loading a drug inside the large diameter portion. a cap that is located on the radial wall of the inner casing at the abutment portion of the tip of the valve body or on the axial center side thereof, and on a radial line segment connecting the inflow port and the outflow port, respectively; an inlet water inlet and an outlet water inlet that are bored and communicate the drug loading space to the opposite side of the radial wall; and a pair of ribs extending parallel to the valve body axis, each rib forming a line connecting the inlet and the outlet when the distal end surface of the valve body abuts the radial wall. When the valve body is separated from the radial wall to the separation limit, each rib is located on a line segment that is perpendicular to the line connecting the inlet and outlet and passes through the axis of the valve body. A drug addition device.
