The rice cooker body comprises an outer port(120) and an inner pot(110) forming an internal space(130) between them. The injection port is to inject oil into the space. The blocking ball with a central channel is located inside the injection port. Oil is injected into the space when the channel of the blocking ball is positioned vertical, and the oil flow is cut off when the channel of the blocking ball is located horizontal. The handle is connected to the blocking ball with a fastening bolt(410) and opens/closes by rotating the blocking ball within a predetermined range.
