A moving assembly of a coffee maker has a body, a first moving module, and a second moving module. The first moving module is mounted to the body, and has a first slide rail and a feeding component. The first slide rail is connected to the body. The feeding component is slidably mounted to the first slide rail and has a nozzle. The second moving module is mounted to the body below the first moving module, and has a second slide rail and a platform. The second slide rail is connected to the body and located below the first slide rail in a direction intersecting with the first slide rail. The platform is slidably mounted to the second slide rail. Therefore, the nozzle may move against a coffee cup put on the platform in two directions with the two independent moving modules.
