Description

Technical Field

[0001] The utility model relates to the technical field of cleaning instruments, and more specifically, to a handheld colorimetric cuvette cleaning instrument. Background Art

[0002] A colorimetric cuvette is an equipment instrument used for spectral analysis. It is mainly a quartz colorimetric cuvette fired from quartz powder and can be cleaned with a dedicated ultrasonic cleaner. When cleaning the colorimetric cuvette, the matte side should face down. There are also micro, semi-micro, fluorescence and other colorimetric cuvettes.

[0003] At present, colorimetric cuvettes are widely used in food safety testing. After use, the colorimetric cuvettes need to be cleaned. However, there is no dedicated cleaning equipment for colorimetric cuvettes. When cleaning, the colorimetric cuvettes are taken out and directly poured into the waste liquid equipment, and then rinsed with water. This not only wastes water resources, but also generates more waste liquid, increasing the waste liquid treatment cost. Summary of the Utility Model

Both liquid extraction peristaltic pumps 3 are electrically connected to the control main board 2. The waste liquid inlet pipe 4 and the clean water outlet pipe 5 are respectively communicated with the two liquid extraction peristaltic pumps 3. The bottom ends of the waste liquid inlet pipe 4 and the clean water outlet pipe 5 are respectively inserted with a waste liquid suction needle tube 6 and a clean water outlet needle tube 7, and the bottom ends of the waste liquid suction needle tube 6 and the clean water outlet needle tube 7 respectively penetrate to the lower side of the housing 1. A waste liquid outlet pipe 8 and a cleaning inlet pipe 9 are fixedly connected to the top end of the housing 1, and the waste liquid outlet pipe 8 and the cleaning inlet pipe 9 are respectively communicated with the two liquid extraction peristaltic pumps 3. A key 21 and a display screen 22 are arranged on the control main board 2.

[0026] In this embodiment, the control main board 2 integrates a key 21 and a display screen 22. When cleaning the cuvette, the waste liquid outlet pipe 8 is connected to a waste liquid bucket, and the cleaning water inlet pipe 9 is connected to a clean water source. The initial water inflow and water outflow to be configured are set through the key 21 on the control main board 2, and the setting result is displayed through the display screen 22. Then, the waste liquid suction syringe needle 6 and the clean water outlet syringe needle 7 are placed into the cuvette with waste liquid. Among them, the height of the bottom end of the clean water outlet syringe needle 7 is higher than that of the bottom end of the waste liquid suction syringe needle 6. Press the cleaning button on the control main board 2 to control the start of a waste liquid outlet pipe 8. A waste liquid outlet pipe 8 sucks out the waste liquid in the cuvette through the waste liquid suction syringe needle 6 and the waste liquid inlet pipe 4, and discharges the waste liquid into the waste liquid bucket through the waste liquid outlet pipe 8. Then, control the start of another liquid extraction peristaltic pump 3. Another liquid extraction peristaltic pump 3 extracts clean water through the cleaning water inlet pipe 9. The clean water enters the cuvette through the clean water outlet pipe 5 and the clean water outlet syringe needle 7. A set amount of clean water is added to the cuvette for cleaning. The waste liquid inlet pipe 4 and the waste liquid suction syringe needle 6 circulate and extract the cleaned water through a liquid extraction peristaltic pump 3. The entire cleaning process is cycled three times. After cleaning, press the key on the control main board 2 to suck dry the cleaning waste liquid inside.

[0027] Specifically, a connector 10 is fixedly connected to the control main board 2, and one end of the connector 10 penetrates through one side end of the housing 1.

[0028] In this embodiment, the control main board 2 is connected to an external power supply and equipment through the connector 10, so that the control main board 2 can control the start and stop of two liquid extraction peristaltic pumps 3.

[0029] Specifically, a battery 11 is fixedly connected inside the housing 1, and the battery 11 is electrically connected to the control main board 2 and two liquid extraction peristaltic pumps 3.

[0030] In this embodiment, the external power supply supplies power to the control main board 2 through the connector 10, and then stores it in the battery 11. The battery 11 stores a certain amount of electricity, so that the control main board 2 and two liquid extraction peristaltic pumps 3 can also be used when not connected to the external power supply.

[0031] Specifically, a front cover plate 12 is fixedly connected to the housing 1, and the control main board 2 is matched with the front cover plate 12.

[0032] In this embodiment, the front cover plate 12 protects the control main board 2, and the key 21 and the display screen 22 on the control main board 2 are exposed for use.

[0033] Specifically, an upper cover plate 13 is fixedly connected to the top end of the housing 1, and both the waste liquid outlet pipe 8 and the cleaning water inlet pipe 9 penetrate through the upper cover plate 13.

[0034] In this embodiment, the upper cover plate 13 protects the two liquid extraction peristaltic pumps 3. At the same time, the waste liquid outlet pipe 8 and the cleaning water inlet pipe 9 are kept stable.

[0035] Working principle: When cleaning the cuvette, set the initial required water inflow and water outflow by pressing the button 21 on the main control board 2. Place the waste liquid suction syringe 6 and the clean water outlet syringe 7 into the cuvette with waste liquid. Press the cleaning button on the main control board 2 to control the start of a waste liquid outlet pipe 8. The waste liquid outlet pipe 8 sucks out the waste liquid in the cuvette through the waste liquid suction syringe 6 and the waste liquid inlet pipe 4, and discharges the waste liquid into the waste liquid bucket through the waste liquid outlet pipe 8. Then, control the start of another liquid extraction peristaltic pump 3. The other liquid extraction peristaltic pump 3 extracts clean water through the cleaning inlet pipe 9. The clean water enters the cuvette through the clean water outlet pipe 5 and the clean water outlet syringe 7, and a set amount of clean water is added to the cuvette for cleaning. The waste liquid inlet pipe 4 and the waste liquid suction syringe 6 circulate and extract the cleaned water through one liquid extraction peristaltic pump 3. The whole cleaning process is cycled three times. After cleaning, press the button on the main control board 2 to suck dry the cleaning waste liquid inside.

[0036] As described above, it is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent replacement or change, and should be covered by the protection scope of the present utility model.
