Graphene-based adjustable electric heating device and adjusting method thereof

Abstract

The invention relates to an adjustable electric heating device based on graphene. The adjustable electric heating device comprises a bottom plate and a heat conducting plate; a cylindrical heating column is fixedly arranged on the bottom plate, and a supporting block and a first graphene heating film are arranged on the top surface of the heating column; the outer side surface of the heating column is longitudinally and slidably sleeved with a first movable ring and an elastic piece providing downward elastic acting force for the first movable ring. An annular second graphene heating film is arranged on the top surface of the first movable ring; the bottom plate is provided with a driving ring which is transversely and rotatably arranged on the heating column in a sleeving manner, and the upper surface of the driving ring is provided with a first wedge-shaped jacking block right opposite to the first movable ring; a first arc-shaped containing groove is formed in the bottom of the first movable ring, and a first jacking slope is arranged at the end of the first arc-shaped containing groove. By applying the structure mode, three application modes including a normal application scene, an auxiliary heating mode and a large-area heating mode can be provided, and the adaptability of the graphene electric heating device can be well improved.

Description

technical field [0001] The present invention relates to the technical field of graphene heating equipment, more specifically, to a graphene-based adjustable electric heating device and an adjusting method thereof. Background technique [0002] Graphene heating film is based on self-prepared graphene powder, and utilizes the extremely low field effect square resistance of graphite material to prepare low-resistance graphene heating film. , it is also soft and resistant to bending, washable and rubbing, to meet the needs of the public for heating equipment; [0003] The heating equipment of the graphene heating film currently used is usually composed of a single fixed heating film, and the area of ​​the heating part cannot be adjusted, so the adaptability is poor. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a graphene-based adjustable electric heating device and its adjustment method for the above-mentioned de...
