Abstract: Disclosed is food-grade lubricating grease and a method for preparing the same, belonging to the technical field of lubricating grease. The food-grade lubricating grease is prepared from the following components in percentage by mass: 75% to 85% of food-grade white oil, 6% to 16% of stearic acid, 2.0% to 3.0% of benzoic acid, 4.7% to 8.7% of aluminum isopropoxide, 1.0% to 1.5% of water and 1.0% to 7.0% of nano-PTFE, and has good extreme-pressure, abrasion-resistant and friction-reduction properties, a last non-seizure load (PB) reaching 411.6 N, a sintering load (PD) reaching 1,960 N, and a friction coefficient reduced by 18.5%. The lubricating grease can be used for a food production industry and in household food appliances, the service life of a device and the service life of the food-grade lubricating grease are effectively prolonged, and meanwhile, food security is guaranteed to a certain degree.

Abstract: A bionic oral cavity structure for testing and application thereof are provided for solving a technical problem that actual test process of the conventional bionic oral cavity structure needs to be improved. The bionic oral cavity structure for testing includes: an upper jaw, a lower jaw, a drive unit, a sensor and a controller, wherein a gum is made of a soft elastic material, and a base of the gum has a through-hole; a cap is formed by extending upward from a top opening of the through-hole; the tooth comprises a molar made of a hard material, and an implant; a top end of the implant passes through the through-hole of the gum and then extends into the cap; the gum and the implant are detachably mounted on the mounting plate; the sensor is a flexible sensor which covers the cap.

Abstract: A portable blowing alcohol concentration measuring device is provided, including: a housing, a valve body, a first one-way valve, a second one-way valve and a container. The first one-way valve can be opened and closed between the air inlet of the housing and the valve body; a container is provided at the other end of the housing, and the housing and the container are spaced by a PTFE membrane; the second one-way valve has a suction port connected to a drainage port on the container. The opening and closing of the second one-way valve can make the passage between the suction port and the inside of the valve body to achieve a pass-through. By optimizing the structure and testing method, the alcohol in the exhaled gas is fully dissolved in the solution in the container, and the blood alcohol concentration can be obtained by direct measurement using the fitted function.

Abstract: The present invention discloses a link motion-based food swallowing simulator comprising a swallowing module including a bionic oral cavity assembly, a shred collecting assembly and a supporting assembly wherein two side plates of a maxillary base of the bionic oral cavity assembly connect to a mounting plate of the supporting assembly, wherein the shred collecting assembly is positioned on a mounting base of the supporting assembly; an adjusting module, positioned under the mounting base, includes a bearing assembly and an adjusting assembly wherein the bearing assembly is disposed on the adjusting assembly, achieving the simulation of the food swallowing mechanism from static to dynamic. The adoption of the driving module realizes the swallowing action through link motion simulation, simulating the swallowing process of the human body and the swallowing process of the patient lying on the back through adjusting modules, improving the swallowing situation with higher adaptability.

Abstract: The present invention discloses a food swallowing simulating device, and belongs to the field of structural design of bio-simulation machinery. The device comprises an upper jaw matrix, a tongue matrix, a transmission device and a driving device; the upper jaw matrix and the tongue matrix are arranged oppositely, and opposite surfaces are curved surfaces; a channel is reserved between the curved surfaces to form a bionic oral cavity; and the tongue matrix is connected with the driving device by the transmission device, so that the motion of the tongue matrix is controlled by the driving device. Transition from static food swallowing mechanism simulation to dynamic food swallowing mechanism simulation is realized, and thus, a blank in the market is made up.
