detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Example 1 shown in Figure 1, the thermal insulation cover of the heat conduction low temperature cigarette includes a first thermal insulation sleeve 1, the inner diameter of the first thermal insulation sleeve 1 is the same as the diameter of the cigarette, and the cigarette can be stuck after the cigarette is inserted, and when it is close to One port of the first thermal insulation sleeve 1 is provided with at least two air inlets as the first air intake channels 2, and the outer wall of the first thermal insulation sleeve 1 is provided with a bump-shaped connector 3 for connecting the heating device. The end of the insulation sleeve provided with the connector is also provided with a stop structure, and the stop structure is a protrusion 13 extending from the inner wall of the heat insulation sleeve to the center. The blocking structure can also be a screen made of fireproof material.
