[0002] Heated cigarettes are typically used in conjunction with corresponding heating devices. The device heats the cigarette to produce an aerosol containing nicotine, which is then inhaled by the consumer. Compared to the high temperatures (above 800°C) of traditional cigarettes, heated cigarettes are typically heated to no more than 400°C, significantly reducing the content of harmful components in the aerosol, mitigating the impact on consumer health, and reducing environmental pollution.

[0003] During smoking, draw resistance is a crucial parameter affecting the consumer experience of tobacco products. The magnitude of draw resistance directly influences the speed and depth at which smoke is inhaled, thus impacting the consumer's satisfaction and overall experience.

[0039] As shown in the figure, this embodiment of the invention provides a smoking device with adjustable draw resistance, including a housing 1, a heating chamber 2 and an air inlet pipe 3 disposed within the housing 1.

[0040] One end of the heating chamber 2 is connected to the outside;

[0041] The inner wall of the air intake pipe 3 forms an airflow channel 31, one end of which is connected to the outside and the other end is connected to the heating chamber 2.

[0042] It also includes a suction resistance adjustment assembly, which includes an adjustment component 4 and an elastic component 5. The elastic component 5 deforms under the action of the adjustment component 4, and the elastic component 5 is at least partially located within the airflow channel 31.

[0043] To address the problems existing in the prior art, this application provides a smoking device with adjustable draw resistance, including a housing 1, a heating chamber 2 and an air inlet pipe 3 disposed within the housing 1, one end of the heating chamber 2 being connected to the outside; the inner wall of the air inlet pipe 3 forming an airflow channel 31, one end of which is connected to the outside, and the other end of which is connected to the heating chamber 2; a draw resistance adjustment assembly is also provided, comprising an adjustment component 4 and an elastic component 5, the elastic component 5 deforming under the action of the adjustment component 4, and at least partially located within the airflow channel 31. The smoking device with adjustable draw resistance provided by this application, through the deformation of the elastic component 5, changes the area occupied by it within the airflow channel 31, thereby altering the area through which air can circulate in the airflow channel 31, thus adjusting the draw resistance of the smoking device, adapting to the draw resistance requirements of different specifications of heated cigarettes, and different consumers' preferences for draw resistance, thus having a wide range of applications; moreover, it has a simple structure, flexible adjustment method, and good practicality.

[0044] Specifically, the housing 1 is provided with a heating chamber 2, one end of which is connected to the outside for inserting a cigarette; the inner wall of the air inlet pipe 3 forms an airflow channel 31, one end of which is connected to the outside and the other end is connected to the heating chamber 2. Air enters the heating chamber 2 from the outside through the airflow channel 31 to bake the cigarette with hot air; the elastic component 5 in the draw resistance adjustment assembly is at least partially located in the airflow channel 31. The elastic component 5 deforms under the action of the adjustment component 4. While changing its shape, the area of ​​the elastic component 5 covering the airflow channel 31 also changes, thereby realizing the adjustment of the draw resistance.

[0045] Preferably, the suction resistance adjustment component is disposed inside the air intake pipe 3, and the gap between the inner wall of the air intake pipe 3 and the suction resistance adjustment component is the airflow channel 31.

[0046] Preferably, the suction resistance adjustment component is located inside the air intake pipe 3. The gap between the inner wall of the air intake pipe 3 and the suction resistance adjustment component is the airflow channel 31. Therefore, the deformation of the elastic component 5 has a greater impact on the airflow channel 31, and the suction resistance adjustment is faster and more efficient.

[0047] Preferably, the adjusting component 4 includes a fixed part 41 and a movable part 42.

[0048] The fixed part 41 is installed inside the housing 1, and the movable part 42 is movably connected to the fixed part 41, moving closer to or away from the fixed part 41;

[0049] The elastic component 5 is located between the movable part 42 and the fixed part 41.

[0050] The preferred adjustment component 4 specifically includes a fixed part 41 and a movable part 42. The fixed part 41 is installed inside the housing 1, and the movable part 42 is movably connected to the fixed part 41, moving closer to or further away from the fixed part 41. An elastic component 5 is located between the movable part 42 and the fixed part 41. When the movable part 42 moves closer to the fixed part 41, it compresses the elastic component 5, causing it to deform more, resulting in greater coverage of the airflow channel 31, a smaller airflow channel 31, and increased suction resistance. When the movable part 42 moves away from the fixed part 41, the elastic component 5 relaxes, reducing the coverage of the airflow channel 31, making the airflow channel 31 larger, and decreasing suction resistance. The suction resistance can be freely adjusted by moving the movable part 42 closer to or further away from the fixed part 41.

[0051] Preferably, the movable part 42 is provided with an external thread, and the fixed part 41 is provided with a matching internal thread.

[0052] The movable connection between the movable part 42 and the fixed part 41 allows for adjustment of the elastic component 5 through various methods, such as setting appropriate damping and providing multiple locking positions. More preferably, the movable part 42 is provided with an external thread, and the fixed part 41 is provided with a matching internal thread. By rotating the movable part 42, it can be moved axially closer to or further away from the fixed part 41, and the threaded engagement allows for stepless adjustment, resulting in more precise adjustment of the suction resistance, and is simple and easy to operate.

[0053] Preferably, the movable part 42 includes a threaded section 421 with external threads, a knob section 422, and a connecting section 423 connecting the threaded section 421 and the knob section 422, with the elastic member 5 sleeved on the outer periphery of the connecting section 423;

[0054] The knob section 422 is located at the end of the movable part 42 away from the heating chamber 2.

[0055] Specifically, the movable part 42 includes a threaded section 421 with external threads, a knob section 422, and a connecting section 423 connecting the threaded section 421 and the knob section 422. The elastic member 5 is sleeved on the outer periphery of the connecting section 423. Rotating the knob section 422 causes the threaded section 421 and the matching internal thread of the fixed part 41 to move relative to each other, so that the connecting section 423 and the sleeved elastic member 5 are close to the fixed part 41 and squeezed by the fixed part 41, or away from the fixed part 41 and the elastic member 5 is released. The knob section 422 is located at the end of the movable part 42 away from the heating chamber 2, that is, at the opening of the air inlet pipe 3 (airflow channel 31), so that it is convenient to adjust by twisting the knob section 422 with fingers.

[0056] The knob section 422 preferably has a corrugated or raised surface to increase friction and facilitate operation.

[0057] Preferably, the elastic component 5 is a ring-shaped airbag.

[0058] The preferred elastic component 5 is an annular airbag, which is inflated and elastic. It deforms when squeezed by external force and recovers its shape when the external force is removed.

[0059] The air pressure inside the airbag can be set as needed, preferably 0.9 Bar ≤ P ≤ 2 Bar, more preferably 0.9 Bar ≤ P ≤ 1.1 Bar. 1 Bar is 101300 Pa, which is one standard atmosphere. The airbag can be set slightly lower than the standard atmosphere, so that the airbag is softer, more elastic and easier to deform, and the cigarette can be inserted smoothly; or slightly higher than the standard atmosphere, so that the elasticity is weaker and the clamping force is stronger.

[0060] Preferably, the fixing part 41 is provided with at least two fixing ribs 411 on its outer periphery. The fixing ribs 411 are fixedly connected to the housing 1 by corresponding slots, and the extending direction of the fixing ribs 411 has an angle with the circumferential direction of the fixing part 41.

[0061] Preferably, the outer periphery of the fixing part 41 is provided with at least two fixing ribs 411, which are fixedly connected to the housing 1 through corresponding slots, so as not to completely block the airflow channel 31; and the extension direction of the fixing ribs 411 has an angle with the circumference of the fixing part 41, and is not completely set along the circumference of the fixing part 41. With the restriction of the slot of the housing, when the movable part 42 is rotated, the fixing part 41 will not rotate with it, but will keep its fixed position unchanged.

[0062] The fixing ribs 411 are preferably provided in 2-8 lengths, more preferably in 4-6 lengths. The extension direction of the fixing member 411 is preferably along the axial direction of the fixing part 41, which facilitates installation and can effectively limit rotation.

[0063] Preferably, a fastening ring 7 is provided at one end of the opening of the heating chamber 2, and the inner diameter of the fastening ring 7 is less than or equal to the outer diameter of the heated cigarette.

[0064] Preferably, the smoking device provided in this application has a fastening ring 7 at one end of the opening of the heating chamber 2 (i.e., the entrance where the cigarette is inserted into the heating chamber 2). The inner diameter of the fastening ring 7 is less than or equal to the outer diameter of the heated cigarette. By utilizing the interference fit between the fastening ring 7 and the cigarette, the cigarette is well and stably clamped and the alignment between the cigarette and the heating chamber 2 is maintained. Furthermore, it can prevent the cigarette from detaching from the heating chamber 2 due to uneven cigarette diameter, heat shrinkage of tobacco substances, or adhesion between the lips and the cigarette, thus ensuring the consumer's smoking experience.

[0065] Preferably, the difference between the inner diameter of the fastening ring 7 and the outer diameter of the heated cigarette is greater than or equal to 0.1 mm; and / or,

[0066] The fastening ring 7 is specifically a ring-shaped airbag.

[0067] Preferably, the difference between the inner diameter of the fastening ring 7 and the outer diameter of the heated cigarette is greater than or equal to 0.1 mm to ensure an interference fit and pressure state between the fastening ring 7 and the cigarette. However, the difference between the inner diameter of the fastening ring 7 and the outer diameter of the heated cigarette should not be too large, otherwise the cigarette will be difficult to insert or may be damaged. Preferably, the difference between the inner diameter of the fastening ring 7 and the outer diameter of the heated cigarette is between 0.1 mm and 0.5 mm. In addition, the outer diameter difference can also be coordinated with the air pressure of the fastening ring 7 to adjust the cigarette insertion and clamping force state.

[0068] The fastening ring 7 is preferably an annular airbag. The air pressure of the annular airbag is preferably 0.9 Bar ≤ P ≤ 2 Bar, more preferably 0.9 Bar ≤ P ≤ 1.1 Bar.

[0069] Preferably, a fixing frame 6 is provided on the outer periphery of the heating cavity 2, and a fastening ring 7 is provided between the fixing frame 6 and the housing 1.

[0070] Preferably, a fixing frame 6 is provided on the outer periphery of the heating chamber 2, and a fastening ring 7 is provided between the fixing frame 6 and the housing 1. The fixing frame 6 and the housing 1 may also be provided with matching annular steps to fix the fastening ring 7.
