Accompanying drawing explanation
Fig. 1 is structural representation of the present invention (profile), the direction that arrow express liquid is mobile;
Fig. 2 is the square section schematic diagram of mark 1,2 and 3 parts in Fig. 1;
In figure, be respectively labeled as: the soft cavity of 1-, 2-hard shell, 3-inner chamber, 4-conduit I, 5-conduit II, 6-pump C, 7-valve, 8-water output duct, 9-conduit III, 10-pump D, 11-constant water bath box, 12-liquid storage bottle, 13-solvent, 14-clip, 15-cigarette filter, the soft cavity upper wall of 16-, the soft cavity inner wall of 17-, 18-chamber outer wall, 19-cavity, 20-pump A, 21-pump B, 22-enters water conduit, 23-extract receiving flask, 24-extract, 25-water.
Embodiment
As shown in Figure 1, 2, device of the present invention is configured to: at the interior soft cavity 1 that simulation human mouth is set of hard shell 2, soft inside cavity has inner chamber 3 that can water-filling, intracavity bottom both sides connect into respectively water conduit 22 and water output duct 8, entering water conduit 22 and water output duct 8 is connected in constant water bath box 11, enter water conduit 22 and be provided with pump B21, water output duct 8 is provided with valve 7; Conduit II 5 is arranged at cavity 19 bottoms of surrounding formation at soft cavity inner wall 17, and conduit II is connected in extract receiving flask 23, and conduit II is provided with pump A20; In constant water bath box 11, have solvent liquid storage bottle 12, liquid storage bottle 12 is provided with conduit III 9 and is connected in extract receiving flask 23, and conduit III is provided with pump D10, is also provided with another conduit I 4 and is connected to the top outside soft cavity in liquid storage bottle 12, and conduit I is provided with pump C 6.Enter water conduit 22 one end and be connected to inner chamber 3 bottoms, water output duct 8 reaches the top of inner chamber 3.
First that cigarette filter 15 is fixing by clip 14 when use, insert and surrounded in the cavity 19 forming by soft cavity inner wall 17, thereby analog roll cigarette filter tip is contained in the state in lip.Then the soft cavity 1 of simulation human mouth is carried out to preheating, first constant water bath box 25 is set to needed temperature, pump B starts working, thermostatted water 25 is entered in the inner chamber 3 of soft cavity 1 by entering water conduit 22 suctions by constant water bath box 11, flow back in constant temperature water tank by water output duct 8 again, thereby form circulation constant temperature current, so that whole soft cavity keeps temperature constant state.Wherein enter the bottom that water inlet that water conduit passes into cavity is positioned at cavity one side, the water delivering orifice of water output duct in cavity is positioned at the top of cavity opposite side, thereby thermostatted water is fully circulated in cavity.
Liquid storage bottle 12 simulate saliva glands, wherein fill the solvent 13 of simulate saliva.After preheating finishes, pump C starts working, and solvent flows to soft cavity upper wall 16 by conduit I with certain flow velocity, with the secretion of simulate saliva.Soft cavity upper wall 16 is higher by cavity outside, lower by cavity center, thereby forms an inclination angle, 15～45 °, the inclination angle forming, and the solvent 13 therefore flowing on cavity upper wall can flow in the cavity 19 at cavity center.Soft cavity inner wall 17 is simulated people's lip, and soft cavity inner wall 17 air spots are sliding, and surperficial continuous separate is furnished with annular groove, and the solvent 13 of inflow can be put aside in these grooves, thereby keeps soft cavity inner wall to be infiltrated by solvent.
