technical field

The utility model relates to the technical field of cigarettes, in particular to an enhanced tobacco dry distillation device.

Background technique

Existing tobacco retort devices use heated air to retort tobacco components. The existing tobacco retort devices adopt the scheme of small-diameter cylindrical air intake holes. Because the fuel wrapped in the outer layer of this scheme is too thick, the fuel burns from ignition to The full combustion process is long, and the user waits for too long, and the thicker fuel also makes it difficult to ignite. The dry distillation effect of the tobacco dry distillation device is affected.

The cuboid metal air inlet channel communicates with the small port of the funnel-shaped heat-gathering chamber, and the large port of the funnel-shaped heat-gather chamber communicates with the interval area of the cylindrical heat-conducting sleeve. , the inner wall of the smoke insertion area is provided with damping protrusions.

The utility model increases the heat exchange area by arranging a cuboid metal air intake passage, which can better control the intake air volume, and better heat the air flowing through, thereby ensuring the dry distillation effect of tobacco. In addition, the utility model can control the temperature of the air sucked into the cigarette inserting area within a reasonable range by setting a funnel-shaped heat-accumulating cavity with a relatively large hot air storage capacity and an interval area connected with the funnel-shaped heat-accumulating cavity. Avoid high temperature to ignite tobacco components and avoid insufficient heating of inhaled air. The dry distillation effect of the cigarette is further ensured. In addition, the heat insulation cover ensures the temperature of the fuel block and the cylindrical heat conduction cover, and at the same time prevents the surface temperature of the tobacco carbonization device from overheating and scalding the user.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

The enhanced tobacco dry distillation device shown in Figures 1 to 3 includes a cylindrical heat-conducting sleeve 1, a rectangular metal air intake channel 2, a funnel-shaped heat-gathering chamber 6, and a cuboid-shaped metal air-intake channel 2 and a funnel-shaped heat-gathering chamber. 6 the fuel block 3 on the outer wall, and the heat insulation sleeve 5 on the outer wall of the cylindrical heat conducting sleeve 1 and the fuel block 3, wherein, the inner cavity of the cylindrical heat conducting sleeve 1 is provided with a cigarette limiting net 4, and the cigarette limiting The bit net 4 divides the inner cavity of the cylindrical heat-conducting sleeve 1 into an interval area 1.1 and a smoke insertion area 1.2. The cuboid metal air intake channel 2 communicates with the small port of the funnel-shaped heat-gathering cavity 6, and the funnel-shaped heat-gathering cavity 6 The large port communicates with the interval area 1.1 of the cylindrical heat conduction sleeve 1, and the inner wall of the smoke insertion area 1.2 is provided with a damping protrusion 1.3. The ratio of the length to the width of the cross-section of the rectangular parallelepiped metal intake channel 2 is 7:1. The rectangular parallelepiped metal air intake channel 2 can increase the heat exchange area, which can better heat the air flowing through it, and ensure the dry distillation effect of the tobacco. The heat insulation jacket 5 wraps the outer wall of the cylindrical heat conduction jacket 1 and the fuel block 3 to ensure the temperature of the fuel block 3 and the cylindrical heat conduction jacket 1 and prevent the surface temperature of the tobacco carbonization device from overheating and scalding the user.

In the above technical solution, the cylindrical heat conducting sleeve 1 , the rectangular parallelepiped metal air intake channel 2 and the funnel-shaped heat collecting chamber 6 are arranged coaxially.

In the above technical solution, the inner wall of the cigarette insertion area 1.2 is provided with two symmetrical upper and lower damping protrusions 1.3. The above two damping protrusions 1.3 are hemispherical damping protrusions. The damping protrusion 1.3 can prevent the cigarette from slipping out of the cigarette insertion area 1.2.

In the above technical solution, the diameter of the inner cavity of the cylindrical heat conducting sleeve 1 matches the outer diameter of the cigarette.

In the above technical solution, the wall thickness of the funnel-shaped heat-gathering chamber 6 is 0.02-0.3 mm. If the metal cylindrical heat conduction sleeve is too thin, it may be burnt out, and if it is too thick, the dry distillation effect is not good. The applicant obtained the above-mentioned range of wall thickness through multiple tests.

In the above technical solution, the axial length of the spacer 1.1 is 1-6 mm. When the axial length of the spacer 1.1 is less than 1 mm, it basically cannot prevent combustion, and when it is greater than 6 mm, the dry distillation effect is not good.

In the above technical solution, since the heat-gathering cavity is a funnel-shaped heat-gathering cavity 6, the fuel block 3 matching the shape of the heat-gathering cavity is also funnel-shaped, so that the above-mentioned fuel block 3 has a thinner part, which is more conducive to the introduction of fuel. Burn, guarantee that fuel block 3 can burn completely. The funnel-shaped heat-gathering cavity 6 can gather hot air here, and the funnel-shaped heat-gathering cavity 6 cooperates with the spacer 1.1 to control the temperature of the air sucked into the cigarette insertion area within a reasonable range, ensuring the dry distillation effect of cigarettes.

In the above technical solution, the spacer 1.1 is used to prevent the burning fuel from passing through the metal to cause the cigarette to burn, and an appropriate space can prevent burning and make the cigarette dry better.

In the above technical solution, the cigarette limiting net 4 limits the insertion depth of the cigarette, leaving an appropriate gap between the cigarette and the funnel-shaped heat-gathering chamber 6 at the front end, effectively avoiding high-temperature ignition of tobacco components. At the same time, since the funnel-shaped heat-gathering chamber 6 is surrounded by scorching fuel after the fuel is ignited, the temperature will be higher than that of the spacer 1.1, which can avoid insufficient heating of the sucked air and reduce the dry distillation effect.

When the utility model is in use, after the fuel block 3 is ignited, the air flowing through the cuboid metal air intake passage 2 and the funnel-shaped heat-gathering chamber 6 will be heated by the metal wall of the cuboid metal air-intake passage 2 and the funnel-shaped heat-gathering chamber 6. The final air gathers in the funnel-shaped heat-gathering cavity 6, and then passes through the interval area 1.1 and the cigarette limiting net 4 in sequence, and enters the cigarette insertion area 1.2, where the hot air in the cigarette insertion area 1.2 performs dry distillation on the tobacco of the cigarette, which greatly reduces harmful components in the smoke. The rectangular parallelepiped metal air intake channel 2 can increase the heat exchange area, which can better heat the air flowing through and ensure the dry distillation effect of tobacco. The temperature in the funnel-shaped heat-gathering chamber 6 is higher than that in the gap area 1.1, which can avoid insufficient heating of the sucked air and reduce the dry distillation effect.

The content not described in detail in this specification belongs to the prior art known to those skilled in the art.
