Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to a sniffing accurate identification ejector and a simulation system based on sniffing intention. Background Art

[0002] Virtual reality (VR) is a technology that immerses users in a virtual world by generating a three-dimensional environment through computers. In the existing field of VR technology, users can experience an immersive experience through vision, hearing and smell. Scent spraying equipment can release corresponding scents in specific scenes, such as floral and food aromas, to further enhance the immersiveness of virtual reality and make the VR experience more real and rich.

[0003] Sham feeding refers to the phenomenon that after food enters the mouth, even if it does not reach the stomach, the color, aroma and other sensory organs of the food stimulate the vagus nerve in the brain and then stimulate the stomach and intestines to secrete gastric juice. At present, there is no odor spraying device directly used in the field of sham feeding. Most of the odor spraying devices in the prior art adopt mechanical or simple electronic control methods, which have problems such as long response time, low control accuracy, and poor adaptability. These shortcomings have a significant impact on the realization of food odor simulation. For example: There is a patent for a technical solution of an odor simulation generating device and operating system based on VR equipment (202211387172.X), which provides an odor simulation generating device and operating system based on VR equipment. By setting an odor generating mechanism and an exhaust component, the odor is automatically changed by rotation, and the scene recognition and data storage module are used to realize the precise release of odor. This solution can quickly provide an odor environment corresponding to the virtual scene, and avoid the previous odor residue during the odor change process, thereby improving the user experience.

[0004] Mechanical devices usually rely on components such as cylinders, pistons and valves to control the release and mixing of odors. These components are difficult to adjust quickly and accurately during operation, resulting in slow release and change of odors. For food odor simulation, a long response time will destroy the user's immersive experience, because the odor experience of food needs to change quickly to match the synchronous perception of vision and taste. For example, when tasting multiple dishes, the smell of each dish needs to be switched quickly, and this delay will seriously affect the user experience. In addition, although simple electronic control methods can achieve a certain degree of automation, their control accuracy is limited, and it is difficult to accurately adjust the concentration and mixing ratio of odors. The simulation of food odors requires high-precision odor release to ensure the true reproduction of the unique aroma of various foods. The problem of low control accuracy will lead to odor distortion or insufficient experience, which is not conducive to the reproduction of delicate and complex odor levels. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a food sniffing precise identification sprayer with fast response speed, high control accuracy and strong adaptability, and a method for using the same in a virtual reality environment.
