[0023] As shown in the figure, an embodiment of the present invention provides a smoking device with adjustable inhalation resistance, comprising a housing 1, a heating chamber 2 and an air inlet pipe 3 arranged in the housing 1, One end of the heating chamber 2 is connected to the outside world; The inner wall of the air inlet pipe 3 forms an air flow channel 31, one end of the air flow channel 31 is connected to the outside, and the other end is connected to the heating chamber 2; A resistance-to-suction adjustment component is also provided. The resistance-to-suction adjustment component includes an adjustment component 4 and an elastic component 5 . The elastic component 5 is deformed under the action of the adjustment component 4 , and at least a part of the elastic component 5 is located in the airflow channel 31 .

[0024] In view of the problems existing in the prior art, the present application provides a smoking device with adjustable inhalation resistance, comprising a shell 1, a heating chamber 2 and an air inlet pipe 3 arranged in the shell 1, wherein one end of the heating chamber 2 is connected to the outside; the inner wall of the air inlet pipe 3 forms an air flow channel 31, wherein one end of the air flow channel 31 is connected to the outside, and the other end is connected to the heating chamber 2; a smoking device with adjustable inhalation resistance is also provided, wherein the smoking device with adjustable inhalation resistance comprises an adjusting component 4 and an elastic component 5, wherein the elastic component 5 is deformed under the action of the adjusting component 4, and the elastic component 5 is at least partially located in the air flow channel 31. The smoking device with adjustable inhalation resistance provided by the present application adjusts the inhalation resistance of the smoking device by changing the area occupied by the elastic component 5 in the air flow channel 31 through the deformation, thereby changing the area of ​​the air flow channel 31 that can flow, thereby adapting to the inhalation resistance requirements of heated cigarettes of different specifications and the preferences of different consumers for inhalation resistance, and having a wide range of applications; and the smoking device has a simple structure, a flexible adjustment method, and good practicality.

[0025] Specifically, a heating chamber 2 is provided in the shell 1, and one end of the heating chamber 2 is connected to the outside world for cigarettes to be inserted; the inner wall of the air inlet pipe 3 forms an air flow channel 31, one end of the air flow channel 31 is connected to the outside world, and the other end is connected to the heating chamber 2. Air enters the heating chamber 2 from the outside through the air flow channel 31 to steam the cigarettes with hot air; the elastic component 5 in the draw resistance adjustment component is at least partially located in the air flow channel 31, and the elastic component 5 is deformed under the action of the adjustment component 4. While changing its shape, the area of ​​the air flow channel 31 covered by the elastic component 5 also changes, thereby achieving the adjustment of the draw resistance.

[0026] Preferably, the suction resistance adjusting component is arranged inside the air intake pipe 3 , and the gap between the inner wall of the air intake pipe 3 and the suction resistance adjusting component is the air flow channel 31 .

[0027] Preferably, the suction resistance adjusting component is arranged inside the air intake pipe 3, and the gap between the inner wall of the air intake pipe 3 and the suction resistance adjusting component is the air flow channel 31. Then, the deformation of the elastic component 5 has a greater impact on the air flow channel 31, and the suction resistance can be adjusted more quickly and efficiently.

[0028] Preferably, the adjusting component 4 includes a fixed portion 41 and a movable portion 42.

The movable portion 42 is movably connected to the fixed portion 41 and moves closer to or farther from the fixed portion 41. The elastic component 5 is located between the movable portion 42 and the fixed portion 41. When the movable portion 42 approaches the fixed portion 41, the elastic component 5 is squeezed to make its deformation larger, so that the airflow channel 31 is covered more, the airflow channel 31 becomes smaller, and the suction resistance becomes larger; when the movable portion 42 moves away from the fixed portion 41, the elastic component 5 is relaxed, and the airflow channel 31 is covered less, the airflow channel 31 becomes larger, and the suction resistance becomes smaller.
