Description

Technical Field

[0001] The invention relates to a smoke absorption device, a bionic device for simulating cigarette smoking and a control method thereof. Background Art

[0002] At present, it is common to simulate the process of human smoking cigarettes through an automatic smoking machine, capture mainstream smoke with a Cambridge filter close to the smoking end of the cigarette, and then conduct chemical composition analysis to evaluate the impact of smoking on the human body. This method only reflects the situation before the smoke enters the oral cavity, which is significantly different from the physiological process when the mainstream smoke is inhaled through the oral cavity, passes through or does not pass through the lungs, and then exhaled from the nasal cavity during actual cigarette smoking. The existing technologies, such as Chinese patents CN106920456A, CN113267434A, CN115598303A and CN115932188A, only simulate the absorption of smoke by the oral cavity, and only study the biophysical and biochemical processes caused by cigarette smoke in the oral cavity to provide devices and methods, without reflecting the overall impact of smoke on the human body when smoking cigarettes. At the same time, the existing bionic absorption device also has the following defects. On the one hand, the bionic absorption material coated on the top wall of the existing bionic absorption device is easy to flow down along the inner wall, resulting in uneven distribution, so that there is a large gap between the amount of smoke absorbed by the bionic absorption device and the actual absorption amount of the human body; on the other hand, the ratio of the internal area to the volume of the existing bionic absorption device is small, the absorption effect of smoke is not good, and the ratio of the internal surface area to the volume of the actual oral and nasal cavity is quite different, and it cannot simulate the absorption of smoke by the human body well. Summary of the invention

[0003] The present invention solves the deficiencies of the prior art and provides a smoke absorption device capable of simulating the effect of smoke on the whole human body when smoking a cigarette, a bionic device simulating cigarette smoking and a control method thereof.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] The first aspect of the present invention provides a smoke absorption device, comprising a shell, wherein the cavity inside the shell is an absorption cavity, the shell is provided with an air inlet and an air outlet, the surface area of ​​the absorption cavity is 1.1.-2.2 times the surface area of ​​a cube of the same volume, and the inner wall of the shell is provided with a coating material layer for absorbing smoke.

[0006] The ratio of the surface area to volume of the absorption cavity in this embodiment is large, so the absorption effect of the absorption cavity is good, and it is closer to the ratio of the inner surface area to volume of the oral cavity and nasal cavity of the human body, and can better simulate the absorption of smoke by the human body.

[0007] In this embodiment, at least one layer of annular first blocking portion is provided on the inner wall of the top of the shell from the inside to the outside, and the first blocking portion extends into the inside of the shell to form a convex ring or extends out of the shell to form a concave ring;

[0008] At least one continuous circle of second blocking parts is arranged on the side wall of the shell in the vertical direction. The second blocking parts are arranged along the circumference of the shell. The second blocking parts extend toward the inside of the shell to form a protrusion or extend toward the outside of the shell to form a depression.

[0009] The provision of the first blocking portion and the second blocking portion increases the ratio of the surface area to the volume of the absorption chamber, and improves the absorption effect of the absorption chamber. At the same time, the first blocking portion makes it difficult for the coating material on the top of the shell to flow down along the side wall, and the second blocking portion makes it difficult for the coating material on the side wall of the shell to flow downward, so the provision of the first blocking portion and the second blocking portion improves the uniformity of the coating material and ensures the absorption effect of the coating material on the top of the absorption chamber.

[0017] The smoke passes through the oral absorption device, lung absorption device and nasal absorption device in sequence, simulating the smoking mode when a person smokes, in which the smoke is inhaled into the mouth, passes through the lungs and is finally discharged from the nasal cavity. The absorption of smoke by the oral cavity, lungs and nasal cavity can reflect the impact of smoke on the human body during the entire smoking process.
