Fan assembly and wall-mounted warm air blower

The utility model relates to a fan assembly and a wall-mounted warm air blower, belongs to the technical field of warm air blowers, and solves the technical problem that a wind wheel in the fan assembly of the existing wall-mounted warm air blower shakes severely during operation due to the fact that the wind wheel is pressed on a rotating shaft of a motor through a nut. The fan assembly comprises a motor provided with a rotating shaft, the rotating shaft is provided with an assembling hole, and the assembling hole penetrates through the rotating shaft in the radial direction of the rotating shaft; the wind wheel is sleeved on the rotating shaft; the rubber nail is inserted and locked in the assembly hole, and the wind wheel is locked on the rotating shaft through the rubber nail. Therefore, when the fan assembly runs, the wind wheel of the fan assembly shakes less, the overall cost is lower, and the fan assembly is simpler and more convenient to assemble. The wall-mounted fan heater adopts the fan assembly.
