Problems solved by technology

However, the chewing process of actual people is accompanied by the dynamic secretion of saliva and the dynamic swallowing action, that is, the amount of saliva and the concentration of chemical substances dissolved in it are updated at any time, and the existing simulated chewing machines cannot imitate this dynamic update process

Embodiment 1

[0051] Use as attached Image 6 The chewing mechanical teeth shown chew gum-based chewing tobacco.

[0052] Put a gum-based chewing tobacco into the solution dish, add 10mL artificial saliva, and set up the chewing mechanical teeth. The working process is as follows: select the 5Kg weight component 4 and install it on the upper chewing lifting shaft 6, and set it to bite up and down at a frequency of 5 seconds. 20 times, set each chewing action to rotate 180° when the upper chewing lifting shaft is lowered 20mm to achieve left and right grinding errors. After biting up and down and grinding the wrong side 20 times, with the cooperation of another artificial tongue, the gum-based chewing tobacco is completely broken. Discharge the solution in the solution dish for main component analysis, and take out the remaining gum-based chewing tobacco samples for further analysis and testing.

Embodiment 2

[0054] The full simulation simulation chewing machine of the present invention is used to simulate the chewing process of gum-based chewing tobacco.

[0055] Put a gum-based chewing tobacco into the solution dish, inject 10ml of artificial saliva, set the chewing mechanical teeth to rotate up and down 20 times at a frequency of 5 seconds, and activate the left and right opening and closing rotating assembly every 4 times. Rotate 45° to do one bite, bite width 15mm, total 5 bites. After the extraction is completed, the solution is extracted to the No. 2 collection station. Inject 10ml of artificial saliva for the second time, rotate and chew 10 times at a frequency of 10 seconds, activate the left and right opening and closing rotating components every 5 times, and do an occlusion every 30° with a occlusion width of 10mm, and a total of 6 occlusions. After completion, the solution is extracted to the No. 3 collection station. Inject 10ml of artificial saliva for the third time, ...

Abstract

The invention discloses a simulated oral cavity which comprises a solution vessel (16) and an opening-closing guide groove (19). The solution vessel (16) is provided with a liquid inlet pipe (15) and a liquid outlet pipe (17). The opening-closing guide groove (19) is arranged in the solution vessel (16), and a pair of clamping assemblies (18) are arranged in the opening-closing guide groove (19). Each clamping assembly (18) is provided with a tooth plate (181), a clamping plate (182) fixed to the tooth plate (181) and a second permanent magnet (183) arranged at the bottom of the clamping plate (182). The simulated oral cavity is used for completely simulating parts of a chewing machine.

Description

Technical field [0001] The invention belongs to the field of bionic machinery, and particularly relates to a simulated oral cavity, which is used as a component of a full-simulation simulation chewing machine. Background technique [0002] With the promulgation of the “Framework Convention on Tobacco Control” (FCTC) ban on the spread of tobacco smoke in public places and the widespread acceptance of the harmfulness of smoking, the country also attaches great importance to harm reduction and coke reduction. Development has become one of the inevitable choices of the tobacco industry. Smokeless tobacco products are tobacco products that are consumed through non-combustion. It is mainly consumed by chewing, sniffing, inhaling, mouthing, and hydrating. It avoids the trouble of traditional cigarettes "second-hand smoke" and has a good market prospect. [0003] As important product forms of smokeless tobacco, bagged mouth tobacco, chewing tobacco and chewing tobacco have received wides...
