Problems solved by technology

Although this technical solution can reduce the temperature of the shell by adding the first air flow channel, the first air flow channel is a straight channel, and the air flow in it is only laminar flow, and the air at the corner is not easy to flow, which leads to the The air in the first air channel is heated unevenly and cannot absorb heat well. There may be gas remaining in the first air channel, resulting in a high local temperature of the shell; at the same time, the temperature of the air entering the cavity is not uniform, which affects the internal temperature of the cavity.

Embodiment 1

[0035] See figure 1 , figure 2 As shown, the heating cigarette smoking set is cylindrical as a whole, and is approximately truncated at the suction side 6 . The battery, power control module and temperature sensor are omitted in the figure, and only the heating head 10 is shown. In this example, a gap with a circular cross-section is formed between the outer wall 2 and the inner casing 1, and three partitions 8 are arranged in the air inlet passage 4 at intervals, and a section of the air inlet passage 4 is divided into two turbulence generation chambers . The shape of three partitions 8 is as follows: image 3 , Figure 4 and Figure 5 As shown, the ventilation holes on each partition 8 are thin stripes extending radially along the partition 8, the number of ventilation holes is not less than two, and the ventilation holes are distributed axially symmetrically on the partition 8; The ventilation hole of the partition 8 is different from the circumscribed angle of the in...

Embodiment 2

[0038] The rest is the same as the embodiment except the partition 8, the partition 8 is divided into at least two fan blades by the air hole 9, the partition 8 has a fan blade shape, so that the passing air can be rotated.

Embodiment 3

[0040] Such as Figure 6 As shown, the heating cigarette smoking set is in the shape of an ellipse as a whole, and its suction side 6 is located at Figure 6 the top of. Figure 7 It is a schematic diagram of the gas circuit structure of a heating cigarette smoking appliance. In this case, the outer wall 2 is oval, and the inner sleeve 1 is circular to match the smoking product 11 . The air inlet channel 4 is formed by the gap between the outer wall 2 and the inner casing 1, mainly on both sides, and three partitions 8 are provided, and two turbulence generation chambers are divided in the air inlet channel 4 . The feature of dividing plate 8 is that it is provided with bigger hole, and the shape of the hole on every dividing plate 8 is different, specifically as Figure 8 , Figure 9 and Figure 10 shown. When sucking, the air enters the air intake channel 4 from the air inlet 5, passes through the vent hole 9 on the partition plate 8, changes the path and speed, and thu...

Abstract

The invention relates to the field of heating cigarettes, in particular to a heating cigarette smoking set gas path structure and a heating cigarette smoking set. The invention provides the heating cigarette smoking set gas path structure capable of uniformly preheating air and effectively reducing the temperature of an outer wall, wherein the heating cigarette smoking set gas path structure comprises an inner sleeve and an outer wall; a smoke gas generation cavity is formed in the inner sleeve; the inner sleeve is nested in the outer wall; an air inlet channel is arranged between the inner sleeve and the outer wall; an air inlet of the air inlet channel is located in one side close to a smoking end of the smoke gas generation cavity; an air outlet of the gas channel is communicated with the air inlet end of the smoke gas generation cavity; and a turbulence generator is arranged in the air inlet channel. According to the structure, a counter-rotating cooling structure is adopted, the cooling effect of the wall of the heater is enhanced by forming the swirling flow by forming the double-rotating gas flow, the preheating airflow with more uniform temperature field distribution is formed, the temperature of the smoke gas inlet during smoking is suitable, and the utilization rate of the heat source is improved to the maximum extent.

Description

technical field [0001] The invention relates to the field of heated cigarettes, in particular to an air path structure of a heated cigarette smoking set and a heated cigarette smoking set. Background technique [0002] It is well known in the art that flavor-producing materials containing tobacco ingredients are heated at a temperature of about 350° C. instead of being burned. These products can be called heated smoking products. Heated smoking products have similar characteristics to traditional cigarettes. Shape, through electric heating or other heating methods, the aroma components and other substances in the aroma-producing materials are released to produce inhalable aerosols, thereby avoiding the production of a large number of harmful components due to high-temperature cracking. While the smoker obtains a sense of satisfaction, the harm to the human body is reduced, and the pollution of the environmental smoke is reduced at the same time. Heated smoking products need...
