Abstract

The present invention provides a heating assembly and a low-temperature smoking set, wherein the heating assembly comprises a heating body and a cavity for containing at least a part of the cigarette, the heating body comprises a base, an infrared radiation layer and an electrode, the base comprises a surface, the infrared radiation layer is arranged on the surface for generating infrared radiation to heat at least a part of the cigarette located in the cavity; at least a part of the electrode is recessed from the surface and buried in the base so that the electrode and the base are formed into an integral structure, and the electrode is electrically connected with the infrared radiation layer. The present utility model well prevents the infrared radiation layer from being scraped off and prevents the electrode from falling off.

Claims (15)

1 . A heating assembly for baking a cigarette, comprising a heating body and a cavity for containing at least a part of the cigarette, the heating body comprising a base formed as a tubular structure having the cavity formed therein, an infrared radiation layer and electrodes electrically connected with the infrared radiation layer, the base having an outer surface facing away from the cavity and an inner surface facing the cavity, and the base having a first end and a second end opposite to the first end along an extension direction of the base, the infrared radiation layer being disposed on a selective surface out of the outer surface and inner surface to cover the selective surface formed between the first end and the second end for generating infrared radiation to heat the at least a part of the cigarette located in the cavity; at least a part of each of the electrodes being disposed and buried in a part of the base which is disposed at a corresponding one of the first end and the second end, and is recessed from the selective surface toward an unselected surface out of the outer surface and the inner surface, so that the each electrode and the base are formed into an integral structure, and the each electrode is electrically connected with the infrared radiation layer for power supply to the infrared radiation layer.

2 . The heating assembly according to claim 1 , wherein the infrared radiation layer covers at least a part of the each electrode so as to be electrically connected with the each electrode.

3 . The heating assembly according to claim 2 , wherein at least a part of the each electrode has a side that is substantially aligned with the selective surface of the base.

4 . The heating assembly according to claim 1 , wherein the each electrode comprises an electrical connection part for providing conductive connection between the heating assembly and other members, and the electrical connection part protrudes from the selective surface relative to the base.

5 . The heating assembly according to claim 4 , wherein the outer surface of the base is configured as the selective surface, and the electrical connection part forms a flange around the outer surface of the base.

6 . The heating assembly according to claim 1 , wherein the each electrode has an opening to form a non-closed ring shape.

7 . The heating assembly according to claim 1 , wherein the inner surface of the base is configured as the selective surface, and at least a part of the each electrode penetrates through the inner surface of the base and extends to the outer surface of the base.

8 . The heating assembly according to claim 7 , wherein the each electrode comprises an annular body and a tab, and the annular body is embedded into the inner surface of the base and buried in the base; the tab is connected with the annular body, penetrates through the base and protrudes from the outer surface.

9 . The heating assembly according to claim 1 , wherein the number of the electrodes is two, and the two electrodes are correspondingly located at the opposite first and second ends of the base.

10 . The heating assembly according to claim 1 , wherein a plurality of elastic convex parts are disposed at the inner surface of the cavity at interval, and each of the plurality of elastic convex parts extends along a transverse direction of the cavity to be closer to one another.

11 . The heating assembly according to claim 10 , wherein an arc-shaped abutting surface is formed at a side of the each of the plurality of elastic convex parts facing a center of the cavity.

12 . The heating assembly according to claim 1 , wherein the base is made from a material having an infrared transmittance of more than 95%.

13 . The heating assembly according to claim 1 , wherein the infrared radiation layer is configured to generate infrared rays with a wavelength ranged from 0.75 μm to 1000 μm.

14 . The heating assembly according to claim 1 , wherein a thickness of the infrared radiation layer is ranged from 30 μm to 50 μm.

15 . A low-temperature smoking set, comprising a housing assembly and a heating assembly, the heating assembly being accommodated in the housing assembly, the heating assembly being the heating assembly according to claim 1 .
