Device for simulating contact between cigarette filter and oral cavity

Abstract

The invention relates to a device for simulating suction of a cigarette filter. The device is constituted as follows: a soft cavity is arranged in a hard shell; an inner cavity is arranged inside the soft cavity; two sides of the bottom of the inner cavity are respectively connected with a water inlet conduit and a water outlet conduit; the water inlet conduit and the water outlet conduit are connected to a constant-temperature water bath; the water outlet conduit is provided with a valve; a conduit II is arranged on the lower part of the cavity formed by surrounding of the inner walls of the soft cavity and connected into an extracting solution collection bottle; a solvent liquid storage bottle is arranged in the constant-temperature water bath; the liquid storage bottle is provided with a conduit III which is connected into the extracting solution collection bottle; the liquid storage bottle is also internally provided with another conduit I which is connected to the upper part of the soft cavity. The device is simple in structure, easy to operate and low in cost, and can be used for more truly simulating the suction process of cigarette filters in the oral cavity of human body.

Description

[0001] technical field [0002] The invention relates to a device for simulating the contact between cigarette filter tip and oral cavity. Background technique [0003] When smoking a cigarette, the contact between the cigarette filter and the human mouth has its own characteristics: (1) The cigarette filter is not completely soaked in saliva when smoking, but the surface is soaked by saliva; (2) most people smoke When smoking a cigarette, the filter tip is not kept in the mouth all the time, but is intermittently in contact with the mouth; (3) There is a suction force on the filter tip when smoking a cigarette, that is, a negative pressure is generated on the filter tip when smoking. [0004] Due to the need for chemical and biological analysis of the process and results of the contact between the cigarette filter and the mouth to assess its potential risks, but currently there is no device that can simulate the contact between the cigarette filter and the mouth, in order t...

Problems solved by technology

[0004] Due to the need for chemical and biological analysis of the process and results of the contact between the cigarette filter and the mouth to assess its potential risks, but currently there is no device that can simulate the contact between the cigarette filter and the mouth, in order to make the cigarette filter contact with the mouth The analysis results are more realistic. It is necessary to develop a device for cigarette filters that can simulate the contact between the filter and the human mouth.
