Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without inventive exercise.

As shown in fig. 1, the soup ladle of the embodiment of the present invention includes a ladle head and a ladle handle, the ladle head and the ladle handle at least have a part of hollow portions, and the hollow portion of the ladle handle accommodates a control module 1, a processing and display module 2, a light source 3, a filter 4, and a first convex lens 5. The hollow part of the spoon head contains a total reflection prism 6, a second convex lens 7 and a photosensitive element 8, and the processing and display module 2 and the photosensitive element 8 are electrically connected with the control module 1. The light source 3, the optical filter 4, the first convex lens 5 and the total reflection prism 6 are sequentially arranged to form a first light path, the total reflection prism 6, the second convex lens 7 and the photosensitive element 8 are sequentially arranged to form a second light path, and the first light path and the second light path are approximately vertical. The total reflection prism 6 is embedded in the hollow part of the spoon head, the surface of the spoon head is flush with the bevel edge surface of the total reflection prism, and the total reflection prism 6 is seamlessly bonded with the surface of the spoon head by edible materials. The hollow part of the spoon handle is also provided with a Bluetooth module 9, and the Bluetooth module is electrically connected with the control module. The hollow part of the spoon handle is provided with a battery 10, and the control module 1, the processing and display module 2, the light source 3 and the photosensitive element 8 are connected with the battery 10. The spoon handle is further provided with a power switch, so that the intelligent soup spoon can be conveniently controlled to be used. The photosensitive element can be CCD or CMOS.

When the spoon is used, a user holds liquid food materials by using the intelligent spoon, the switch is turned on, the whole electric system and the whole optical system are enabled to enter a ready state, meanwhile, the light source 3 emits light rays, the light rays move in each optical element, and finally, data are displayed on the processing and display module 2 through a calculation process.

In detail, the optical element of the invention adopts the principle of liquid refraction, utilizes as few optical elements as possible to achieve the required function, the light path structure can be adjusted according to the spoon shape and the size, and only the light path principle needs to be ensured, and the process specifically comprises the following steps:

the system operates with light generated by the light source 3, which first passes through the filter 4, leaving only a single specified wavelength of light. The light is focused on one point of the hypotenuse facet of the total reflection prism 6 by the first convex lens 5, so that the incident light includes different incident angles. The liquid food material sample is in direct contact with the other surface of the prism of the total reflection prism 6. The critical angle for total internal reflection will vary depending on the refractive index of the liquid sample. Incident light below the critical angle of total internal reflection is partially reflected to the other side of the total reflection prism 6, and the rest light is refracted into the test liquid sample; whereas incident light above or equal to the critical angle for total internal reflection will undergo total internal reflection. The reflected light, which is partially reflected by the light rays including total internal reflection, passes through the second convex lens 7 on the photosensitive element 8. The light sensing element 8 converts the collected light into digital signals, the digital signals are transmitted to the processing and display module 2, the control module 1 collects refraction data, the refractive index of the liquid can be calculated, and then the data are converted into specific gravity and concentration. I.e. a display can be made. The method for detecting the critical angle of total internal reflection can measure the refractive index of a liquid sample or a liquid sample containing bubbles or solid particles, and can measure the corresponding result by only needing a small amount of the liquid sample. Meanwhile, the control module 1 is internally provided with a data standard, and if the content of a certain substance in a certain food is too high (such as salt), the light source 3 is controlled to flicker, so that a user is prompted to pay attention to diet health.

In addition, data can directly be shown on the display screen, also can the operating control system, adopts the bluetooth with data transmission to smart mobile phone end, record and higher order analysis to data to this lets the more comprehensive health information of mastering of user.

This intelligence soup ladle uses portably, only needs open the switch, just can open intelligent soup ladle. After the intelligent soup ladle is opened, the Bluetooth module can be automatically connected with the associated mobile phone, and a user can only use related programs to perform more complex operations. Put intelligent soup ladle in liquid, the light source data that photosensitive element 8 received change, begin to carry out the analysis to sensing liquid, will obtain electric signal output to handling and display module 2 in, processing system obtains the oil salt sugar concentration in the liquid according to above-mentioned work flow. The processing and display module 22 displays the concentrations of oil, salt, sugar and the like in the liquid in real time. When the concentration of the oil exceeds the standard, the light source 3 flickers yellow; when the concentration of the salt exceeds the standard, the light source 3 twinkles blue, and when the concentration of the sugar exceeds the standard, the light source 3 twinkles red; when the concentration of the oil-salt sugar is not over standard, the light source 3 is not bright.
