The invention belongs to the technical field of electric water heaters, and particularly relates to a spherical flexible connection composite structure of a through type double-container electric water heater. The situation that two sets of connecting pipelines cannot be accurately installed due to over-positioning of the upper inner container and the lower inner container is avoided; the technical problem is solved by providing the spherical flexible connection composite structure for the through-type double-container electric water heater, so that effective sealing of a connecting pipeline is ensured, and the distance between the inner containers is reduced as much as possible. Specifically, the upper container connecting pipeline and the lower container connecting pipeline are connected together in an inserted mode. A contact surface between an upper half section pipeline and a lower half section pipeline of the conical lower container connecting pipeline is a spherical surface, and a sealing ring is arran
