When starting to use, the user uses a smart spoon to hold his liquid food, turns on the switch, and makes the entire electrical system and optical system enter a ready state, and at the same time, the light source 3 emits light, and the light moves in each optical element. Finally, through the calculation process, The data is displayed on the processing and display module 2 .

In detail, the optical element of the present invention adopts the principle of liquid refraction, and uses as few optical elements as possible to achieve the required function. Yes, the process is as follows:

The system will use the light generated by the light source 3 to work, and the emitted light will first pass through the filter 4, and the filtered light will only have a single specified wavelength of light. The light is focused on a point on the hypotenuse facet of the total reflection prism 6 through the first convex lens 5, so that the incident light includes different incident angles. The liquid food sample is in direct contact with the other side of the prism of the total reflection prism 6 . Depending on the refractive index of the liquid sample, the critical angle for total internal reflection will vary. The incident light below the critical angle of total internal reflection will be partially reflected to the other side of the total reflection prism 6, and the rest of the light will be refracted into the test liquid sample; while the incident light above or equal to the critical angle of total internal reflection will be totally reflected. internal reflection. The reflected light, including the partially reflected light of the total internal reflection light, passes through the second convex lens 7 on the photosensitive element 8 . The photosensitive element 8 converts the collected light into a digital signal and transmits it to the processing and display module 2. The control module 1 collects the refraction data, and can start to calculate the refractive index of the liquid, and then convert it into specific gravity and concentration. display can be performed. This method of detecting the critical angle of total internal reflection can measure the refractive index of liquid samples or liquid samples containing air bubbles or solid particles, and requires only a small amount of liquid sample to measure the corresponding results. At the same time, there is a built-in data standard in the control module 1. If the content of a certain substance in a certain food is too high (such as salt), the light source 3 will be controlled and start to flash, prompting the user to pay attention to healthy diet.

In addition, the data can be directly displayed on the display screen, or the control system can be operated, and the data can be sent to the smartphone via Bluetooth, and the data can be recorded and analyzed at a higher level, so as to allow users to have a more comprehensive understanding of their health. information.

The smart soup spoon is easy to use, and the smart soup spoon can be turned on simply by turning on the switch. After the smart spoon is turned on, the Bluetooth module can automatically connect to the associated mobile phone, and users can perform more complex operations with only the relevant programs. Put the smart spoon in the liquid, the light source data received by the photosensitive element 8 changes, start to analyze the sensed liquid, and output the obtained electrical signal to the processing and display module 2, and the processing system obtains according to the above workflow. The concentration of oil, salt and sugar in the liquid. The processing and display module 22 displays the concentration of oil, salt, sugar, etc. in the liquid in real time. When the concentration of oil exceeds the standard, light source 3 will flash yellow; when the concentration of salt exceeds the standard, light source 3 will flash blue; when the concentration of sugar exceeds the standard, light source 3 will flash red; when the concentration of oil, salt and sugar does not exceed the standard , the light source 3 will not light up.
