This device is a system in which a part of running water is guided to a drug filling chamber by utilizing a pressure difference, and the solid drug is brought into contact with the drug to dissolve it, and the solid drug is returned to the running water. For example, when targeting a pool, a charging device with a chemical filling chamber is installed in the middle of the flow path forcibly circulating with the external filter, and the flowing water is taken into and out of the chemical filling chamber due to the pressure difference. The solid drug accumulated in the drug filling chamber is contacted with water to dissolve the drug and return it to the pool. When targeting the pool, calcium hypochlorite is used as a drug.
