A portable heating device of the present invention comprises: a support unit supported by a structure in which the support unit is spaced apart from a bottom surface by support pieces radially arranged, and having an air inlet hole provided on a lower side thereof, and an upward air movement hole provided on an upper side thereof; an air circulating unit provided on an upper portion of the support unit, and having an internal body passing therethrough, and an external body having a structure in which the internal body is included in the external body, spaced apart from an outer circumferential portion of the internal body, and forming an upward air movement path; a combustion unit installed in a structure in which the combustion unit is spaced apart from an inner circumferential portion of the internal body on an inside of the internal body of the air circulating unit, and continuously circulating air through a downward air circulating hole and an upward air circulating hole; a blowing unit sucking external air, moving the external air to the upward air movement path provided between the internal body and the external body of the air circulating unit, and continuously circulating air moved to upper portions of the internal body and the external body to the upward air circulating hole through the downward air circulating hole of the combustion unit; a heat sink unit provided between the combustion unit and the support unit to radiate heat transmitted from the combustion unit to the support unit; and a power supply unit installed adjacently to the blowing unit to supply power to the blowing unit. Therefore, fire power may be increased, and user convenience may be improved by providing indoor or outdoor uses or the like while providing portability. |
