▎ 摘　　要

NOVELTY - The modular graphene indoor electric heating device comprises an air extraction assembly that is connected with an air outlet heating assembly. A graphene heating core tube is sleeved in an outer sleeve. The air intake joint is installed on the outer side wall of the outer sleeve. A flow guide end cap is buckled on the outer sleeve. The flow guide end cap extends to the inner side of the inner wall of the graphene warm core cylinder to form a convex ring. The air inlet connector is formed with an air inlet cavity. The diversion end cover is formed with an annular diversion cavity. Multiple air outlets are formed along the radial direction. The air outlet is communicated with the diversion cavity. The air exhaust assembly includes a housing, air exhaust mechanism, and air outlet connector. The air exhaust mechanism is installed in the housing. The air outlet connector is installed on the housing and connected with the air inlet connector. A suction cavity is formed in the housing. USE - Modular graphene indoor electric heating device. ADVANTAGE - The modular graphene indoor electric heating device has the advantages of high thermal efficiency and energy saving. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a modular graphene indoor electric heating device.
