BAKING TYPE HEATING DEVICE FOR ELECTRONIC CIGARETTE HAVING HEAT PRESERVATION CUP

摘要

A baking type heating device for an electronic cigarette that has a heat preservation cup (1), the device comprising the heat preservation cup (1), a heating cup (2) and a wire (3), wherein the heat preservation cup comprises an inner cup body (11), an outer cup body (12) and an annular pressing lid (13); the inner cup body (11) is sleeved inside of the outer cup body (12); a heat insulating gap (10) is disposed between the inner cup body (11) and the outer cup body (12); a lower portion of the inner cup body (11) and a lower portion of the outer cup body (12) are connected and provided with a tube body that penetrates a wall portion of the inner cup body and a wall portion of the outer cup body; the annular pressing lid (13) is simultaneously disposed in a sealed manner on a cup opening portion (112) of the inner cup body (11) and the cup opening portion (112) of the outer cup body (12) from top to bottom; and the heat insulating gap (10) forms a vacuum after assembling and processing. The beneficial effects thereof are that the heat preservation cup (1) that is provided with an internal vacuum has a good heat preservation effect, such that the efficiency of heating the cigarette is improved, and heat is not easily radiated to the outside, thus preventing high temperature ablation or damage from occurring due to heat conduction or radiation to the outside; the heating cup (2) does not allow e-liquid and dirt to fall inside of the electronic cigarette, thus preventing pollution and damage, and the heating cup (2) is provided with a clamping portion to prevent direct contact from occurring between the cigarette and the inner wall of the heating cup (2), thereby preventing a burnt flavor due to local high temperatures.
