Embodiment Construction

[0035] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] Specific embodiment one of the artificial oral cavity device of the present invention, as Figure 1 to Figure 2 As shown, the artificial oral cavity device includes an artificial oral cavity and a film adsorption material 3 . The artificial oral cavity includes a shell, which can be made of inert materials such as stainless steel, glass, and polytetrafluoroethylene. The housing includes an inner cavity 8 surrounded by a cuboid in the middle and curved surfaces at both ends, which is used to simulate the human oral cavity. Preferably, the inner cavity volume is 50-80cm 3 , close to the real mouth size. The housing also has a flue gas inlet 11 and a flue gas outlet 12 connected to the inner cavity 8, and a film adsorption material 3 is attached to the inner wall of the inner cavity 8, and the film adsorption material 3 fully absorbs liquids such a...

Abstract

The invention provides an artificial mouth and an artificial mouth device. The artificial mouth comprises a housing with an inner cavity. The housing is provided with a smoke inlet and a smoke outlet and the smoke inlet and outlet are communicated with the inner cavity. The housing also comprises thermal insulation structures which are respectively arranged at the inner side and/or outer side of the inner cavity and are used for keeping the temperature in the inner cavity. Through detection of smoke adsorbed by a film adsorption material in the artificial mouth device under the condition of the constant temperature, evaluation and analysis of chemical components of mouth smoke and sucked smoke are realized and the evaluation and analysis results provide important reference values for cigarette sensory quality improvement.

Description

technical field [0001] The invention relates to an artificial oral cavity and an artificial oral cavity device. Background technique [0002] The chemical composition evaluation of cigarette smoke is the main method to evaluate the quality and safety of cigarettes. The existing method usually uses a special smoking machine to smoke the burning cigarette, and uses the Cambridge filter to capture the chemical composition in the smoke, thereby Analyze the release amount of tar, nicotine, flavor components, harmful components, etc. in cigarette smoke. However, when people smoke cigarettes, the smoke first enters the mouth, and then enters the lungs, and the mouth is an environment with a certain space volume and temperature and humidity, the cigarette smoke will diffuse and dilute in the mouth, and some chemical components will be in Oral epidermis and tongue surface are adsorbed, thereby producing sensory characteristics such as taste and stimulation. The scientific analysis ...
