A central rod is attached to the drive rod and drivable by the drive rod to rotate around the axis direction with the drive rod. A solid material container has one or more compartments to store solid materials to be dispensed. A switch valve is rigidly attached to the central rod and drivable by the central rod to rotate around the axis direction with the central rod. A container bottom of the solid material container comprises one or more first component shapes that form one or more first interstitial void spaces. The switch valve comprises one or more second component shapes that form one or more second interstitial void spaces.
