The invention relates to a moving-noise-free intelligent heating robot based on internet of things. The heating robot comprises a main body, a guide rail, a suspension mechanism, a heating plate, a humidifying mechanism and a central control mechanism; the suspension mechanism comprises two suspension assemblies, each suspension assembly comprises an undercarriage, a guide electromagnet and a magnetic levitation electromagnet, the humidifying mechanism comprises a water tank, a vibration assembly and a spraying assembly, the vibration assembly comprises a driving unit and a vibration unit, thespraying assembly comprises a shell, a supporting rod, a control unit and an angular adjusting unit. According to the moving-noise-free intelligent heating robot based on internet of things, the suspension mechanism is arranged, the robot can more stably and quietly move, generation of noise is reduced, people can have a more comfortable rest, the humidifying mechanism is arranged, the room can be evenly humidified more efficiently, the condition that due to heating, the room air is too dry is avoided, and through the mechanisms, the practicability of the heating robot can be greatly improved.
