Simulated tongue pressure head mechanics detection device

Abstract

The invention provides a simulated tongue pressure head mechanics detection device characterized by comprising: a base, a supporting guide pillar which is fixed on the base, a pressure arm which is arranged on the supporting guide pillar, a removable simulated tongue pressure head which has a simulated tongue shape and is clamped by a power head of the pressure arm, a line-row distributed pressure sensor which is arranged at the upper surface of the base right under the simulated tongue shaped simulated tongue pressure head. The line-row distributed pressure sensor is electrically connected to a data collection hand grip; the data collection hand grip is in signal connection with a computer through a USB interface. The device can simulate changes of tongues to detect oral cavity internal mechanics information; the device can be applied in food field to detect texture properties of samples to be tested and the results are closer to human senses so that the invention provides a new device for objectively, accurately and quickly evaluating food texture.

Description

technical field [0001] The invention relates to an imitation tongue-pressing-head mechanical detection device manufactured by simulating the shape change of the human tongue surface. Background technique [0002] During the process of human chewing food, the main receptor in the oral cavity is the tongue, and the stress distribution information on the surface of the tongue changes with the series of movements of the tongue when the surface of the tongue is in contact with food of different degrees. Acquiring the texture and taste of food is especially important. At present, there is no instrument for the detection of mechanical information inside the oral cavity, and some mechanical properties of materials can only be completed by equipment such as texture analyzers. However, most of the existing texture instrument detection probes have simple geometric structures such as cylindrical and conical. It is not related to the tongue, and mainly detects the crushing and extrusion...

Problems solved by technology

At present, there is no instrument for the detection of mechanical information inside the oral cavity, and some mechanical properties of materials can only be completed by equipment such as texture analyzers. However, most of the existing texture instrument detection probes have simple geometric structures such as cylindrical and conical. It is not related to the tongue, and it mainly detects the crushing and extrusion force of a single point of material. It cannot reflect the distribution of mechanical information changes when chewed food fragments enter the mouth and contact the tongue surface, which is quite different from human senses.
