Description

[Technical Field]

[0001] This utility model relates to a liquid concentration detector. [Background Technology]

[0002] A refractometer is a device for measuring the refractive index of a liquid. Since the refractive index of a liquid increases when a solid soluble substance dissolves, the content of this solid soluble substance can be measured by measuring the refractive index. Therefore, a refractometer can be used to measure the content of solid soluble substances in a liquid. Solid soluble substances in aqueous solutions are often sugars, so a refractometer is also called a saccharimeter when measuring beverages (such as juice and coffee).

[0003] Existing refractive liquid concentration detectors generally have complex structures and numerous components, making them difficult to assemble quickly and accurately. Furthermore, the accuracy of the components after assembly is low, resulting in low detection accuracy. [Utility Model Content]

During assembly, the spherical lens 7 is placed on the base through hole 3 of the base cavity 2 of the base 1, and the sealing cover 6 is closed to form a light-free enclosed space in the base cavity 2. The inner ends of the incident pipe 4 and the outgoing pipe 5 are connected to the base cavity 2 respectively. At this time, the fixing component 8 fixes the spherical lens 7. Finally, the infrared component 9 and the detection camera component 10 are installed on the outer ends of the incident pipe 4 and the outgoing pipe 5 respectively, achieving rapid and accurate assembly. In application, the bottom surface of the liquid concentration sensor is placed on the detection liquid, that is, the spherical lens 7 is placed on the detection liquid. After the infrared component 9 emits infrared rays outward, the infrared rays enter the base groove 2 through the incident pipe 4 and are incident on the spherical lens 7. After being reflected by the liquid and the spherical lens 7, the infrared rays enter the outgoing pipe 5 and are received by the detection camera component 10 for data detection. The concentration of the detection liquid is then calculated by the control module, simplifying the overall structure.

The inlet pipe 4 and the outlet pipe 5 are respectively located between the two protrusions 12. The cover 6 has a cover connection part 13 that covers the protrusions 12. The inner end of the inlet pipe 4 has an inwardly extending inlet pipe positioning protrusion 14, and the inner end of the outlet pipe 5 has an inwardly extending outlet pipe positioning protrusion 15. The cover 6 has a cover groove 16 that cooperates with the inlet pipe positioning protrusion 14 and the outlet pipe positioning protrusion 15 respectively, which facilitates quick positioning and installation of the cover 6 and sealing of the base cavity 2.

[0030] like Figure 5-7As shown, the infrared component 9 is located at the end of the outer side of the incident pipe 4. The infrared component 9 includes an infrared cover plate 91 that covers and seals the outer side of the incident pipe 4. An infrared emitting tube 92 is provided on the inner side of the infrared cover plate 91. The structure is simplified. The infrared cover plate 91 keeps the incident pipe 4 in a closed and unaffected state.
