Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of electronic cigarettes, and more particularly, the present invention relates to a heated non-combustible electronic cigarette.

Background technique

[0002] Generally, cigarettes emit cigarette smoke for smokers to inhale when burning in open flames, and cigarettes decompose to produce smoke tar, carbon monoxide, phenol, nitrogen oxides, olefins, and polycyclic aromatic hydrocarbons when burning in open flames. And other harmful substances, which can seriously harm human health. In order to prevent cigarettes from producing a large amount of harmful substances and to enjoy the unique flavor of cigarettes, a non-combustible electronic smoking device has been created in the market. Its role is to place tobacco products (such as cigarettes and tobacco cores) in the smoker when smoking. Electric heating, baking the tobacco product at a temperature lower than the flammable temperature of the tobacco product until it smokes, allows the smoker to inhale the cigarette smoke. Tobacco products are burned by heating instead of open flames, which prevents users from inhaling a large amount of harmful substances produced by open flames of tobacco products. Therefore, electronic smoking devices are widely used for smoking.

[0003] 5 Some heating non-combustible electronic smoking appliances, heating the outer wall of the cigarette body through a heating cup, because the heating cup is closely attached to the outer wall of the cigarette body to continuously generate high temperature, high-temperature heat is also passed to the outside through the outer wall of the heating cup Conduction or emission, and the prior art has no obvious thermal insulation effect on the outer surface of the heating cup. Long-term operation of the electronic smoking device will still cause the external temperature of the smoking device to be too high, which may easily cause hot hands and cause poor user experience.

A baking device, a battery, a circuit control board, and a key switch are provided. The key switch is exposed on the surface of the housing through a through hole provided in the housing, and is characterized in that the baking device includes a heating cup and heat insulation. The heating cup is used for containing and baking cigarettes, the heating cup is sleeved in the heat insulation tube, the heat insulation tube includes a vertical wall and a bottom wall, and the vertical wall of the heat insulation tube is provided inside There is a closed heat insulation cavity, and the heat insulation cavity is filled with a heat insulation medium or a cooling medium.

[0006] Preferably, the thermal insulation cavity is a circular cavity.

[0007] Preferably, a tubular body protruding upward is provided on the bottom wall of the thermal insulation cylinder, a threading hole is provided at the bottom of the tubular body, and a gap between the tubular bodies constitutes a thermal insulation gap.

[0008] Preferably, the casing is formed in a rectangular box shape, the baking device is disposed on one side in the casing, and the battery is disposed on the other side in the casing.

[0009] Preferably, the heating cup is made of a ceramic material.

[0010] Preferably, the heat insulation cylinder is made of PEEK material or stainless steel metal material.

[0011] Preferably, the thermal insulation medium is an aerogel.

[0012] Preferably, the cooling medium is water.

The beneficial effects of the invention

Beneficial effect

[0013] A heat insulation tube is provided outside the heating cup, and a heat insulation medium or cooling medium is provided in the vertical wall of the heat insulation tube. The heat insulation medium or cooling medium can block or absorb heat, and the bottom wall of the heat insulation tube is also provided. The heat insulation gap greatly reduces the heat transmitted or dissipated from the heating cup, not only increases the working efficiency of the heating cup, but also avoids the problem that the temperature of the surface of the electronic cigarette case is too high and it is easy to burn your hands, resulting in poor user experience.
