Heating element
View Patent ↗A heating element includes a body, a heating wire, and two pins. The body is a concave member including a through hole. The two pins are disposed on two ends of the heating wire, respectively.
1. A heating element for vaporizing an e-liquid, comprising a vaporizing body, a heating wire for generating heat and transferring heat to the vaporizing body, and two pins; wherein:
the vaporizing body is adapted to contain the e-liquid, and the vaporizing body is adapted to receive heat from the heating wire and vaporize the e-liquid to generate vapor;
the vaporizing body comprises a plate member, a columnar member, and a through hole;
the plate member comprises a first flat surface and a second flat surface opposite to the first flat surface;
the columnar member extends out from the first flat surface;
the heating wire has a flat structure and is attached to the second flat surface;
the through hole extends through the plate member and the columnar member, and is adapted to convey the vapor;
the two pins are disposed on two ends of the heating wire, respectively;
the shape of the columnar member is one of a cylinder, a cube, and a polygon; and the vaporizing body comprises quartz, mica, jade, or a combination thereof; and
the columnar member comprises a first flat end surface connected to the first flat surface, a second flat end surface opposite to the first flat end surface, and an annular recess indented from the second flat end surface towards the first flat end surface.
2. The heating device of claim 1 , wherein the heating wire is formed by more than two alloy wires arranged in one plane, and the more than two alloy wires are disposed in parallel or in series.
3. The heating device of claim 1 , wherein the plate member has a larger diameter than the columnar member whereby a step is formed around the columnar member.
4. The heating device of claim 1 , wherein a shape of the through hole is one of a circle, ellipse, triangle, quadrilateral, polygon, and mesh.
