The longitudinal flow type annular PTC heater of the invention is a heating component for forming a multifunctional fan lamp, so the longitudinal flow type annular PTC heater of the invention is described by combining the whole fan lamp as follows:

in one embodiment of this embodiment, as shown in figure 3, it is used in a ceiling fan lamp comprising a fan body 14 and a longitudinal flow annular PTC heater and lighting assembly, the fan body 14 comprising a base 6 attached to the ceiling, a fan motor built into the base, a fan motor output shaft passing through the lower opening of the base, the output shaft connecting with fan blades 7, said fan blades 7 being used for blowing. The side of the base 6 is connected with a plurality of connecting rods 8 which are hollow and used for accommodating power wires, the lower ends of the connecting rods 8 are connected with the longitudinal flow type annular PTC heater 1 and the lighting assembly 9, the PTC heater 1 is perpendicular to the output shaft of the motor and is positioned above or below the fan blades 7, the connecting rods are preferably arranged below the PTC heater, the fan blades 7 rotate to generate downward air flow, the air flow is heated and blown downwards to be used for indoor heating when passing through the heat dissipation fins 22, and the lighting assembly can be arranged in the annular middle or outside of the longitudinal flow type annular PTC heater, and is preferably arranged in the annular middle.

It should be noted that the fan body 14 may be a conventional ceiling fan or a ceiling fan, which is not limited in the present invention. Since the fan body 14 is a commercially available ceiling fan, the structure thereof is well known to those skilled in the art and will not be described herein.
