Description

Technical Field

[0001] The utility model relates to the technical field of cuvettes, in particular to a flexible cleaning mechanism for cuvettes. Background Art

[0002] The cuvette is generally a rectangular parallelepiped with the bottom and two sides made of frosted glass and the other two sides made of optical glass and bonded together by light-transmitting surfaces. The cuvette is the most commonly used device for photometric analysis. Care should be taken to protect the light-transmitting surface and the frosted glass surface should be pinched when taking it. When cleaning the cuvette, a flexible cleaning mechanism for the cuvette is required.

[0003] At present, when cleaning the cuvette, the staff generally uses a cotton swab to dip in a suitable cleaning agent, and then manually wipes the area of ​​the cuvette that needs to be cleaned, so as to clean the cuvette.

When the number of cuvettes to be cleaned is large, the staff's workload will increase, thereby reducing the cleaning efficiency and effect of the cuvette. Moreover, after the cleaning of the cuvette is completed, the cuvette is generally allowed to dry naturally, which will result in the cuvette being unable to be used immediately after cleaning, thereby reducing the use efficiency of the cuvette.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 - Figure 6 As shown, this embodiment provides a flexible cleaning mechanism for a cuvette, comprising a support table 1, and further comprising:

[0029] The adjusting plates 2 are symmetrically arranged on the upper surface of the supporting platform 1. The upper surfaces of the two adjusting plates 2 are fixedly connected with transmission plates 3. A lifting plate 4 is arranged below the transmission plates 3.

[0030] The adjusting components are respectively arranged inside the two adjusting plates 2 and are used to adjust the height position of the lifting plate 4;

[0031] The fixing components are arranged at equal intervals at the bottom of the lifting plate 4 and are used to fix the colorimetric cell body 5;

[0032] The cleaning frames 6 are arranged at equal intervals on the upper surface of the support platform 1. A cleaning sponge 19 is arranged inside each of the cleaning frames 6. A mounting sleeve 20 is fixedly connected to the bottom of each of the cleaning sponges 19. A mounting plate 21 is arranged inside each of the mounting sleeves 20.

[0033] The mounting components are respectively arranged inside the plurality of mounting plates 21 and used to fix the mounting sleeve 20 and the mounting plate 21;

[0034] A driving assembly is disposed at the bottom of the support platform 1 and is used to drive the multiple cleaning sponges 19 to rotate synchronously;

[0035] The air-drying component is arranged on the front end surface of the supporting platform 1 and is used to air-dry the cleaned cuvette body 5 .

[0036] The above working principle: when it is necessary to clean the cuvette body 5, it is only necessary to first fix the cuvette body 5 under the lifting plate 4 through the fixing component. When the cuvette body 5 is fixed, the prepared cleaning agent is added to the inside of the cleaning frame 6. At this time, the adjusting component starts to run, and the adjusting component can effectively drive the lifting plate 4 to move downward synchronously, and the lifting plate 4 then drives the cuvette body 5 to move downward synchronously. When the cuvette body 5 is plugged into the outside of the cleaning sponge 19, the driving component starts to run. At this time, the driving component can effectively drive the cleaning sponge 19 to rotate synchronously. During the rotation of the cleaning sponge 19, the cleaning agent can be used to effectively clean the cuvette body 5. When the cleaning of the cuvette body 5 is completed, the adjusting component will drive the cuvette body 5 to rise synchronously. When the cuvette body 5 rises, the air-drying component starts to run. At this time, the air-drying component can effectively air-dry the cuvette body 5, thereby improving the cleaning efficiency and use efficiency of the cuvette body 5, saving time and effort.

[0037] In order to effectively adjust the height position of the lifting plate 4 so that the lifting plate 4 can effectively drive the cuvette body 5 to move synchronously, the adjustment component includes threaded rods 9 that are rotatably connected to the bottom ends of the two adjustment plates 2 respectively, and the top ends of the two threaded rods 9 extend to the inside of the transmission plate 3 and are rotatably connected to the top end of the inside of the transmission plate 3. The upper surface of the transmission plate 3 is fixedly connected to a first motor 8, and the output shaft of the first motor 8 is fixedly connected to the top end of one of the threaded rods 9 through a coupling.

The outsides of the two threaded rods 9 are threadedly connected to threaded blocks 10, and guide grooves for the movement of the threaded blocks 10 are provided on opposite sides of the two adjustment plates 2. The opposite sides of the two threaded blocks 10 are fixedly connected to the two sides of the outer wall of the lifting plate 4 respectively. When the height position of the lifting plate 4 needs to be adjusted, the first motor 8 starts to run, driving one of the threaded rods 9 to rotate synchronously. Since the two threaded rods 9 are connected by a belt 11 and a driving wheel for transmission, the two threaded rods 9 will rotate synchronously at this time, and the threaded blocks 10 will move synchronously outside the threaded rods 9, driving the lifting plate 4 to move synchronously. At this time, the height of the lifting plate 4 can be adjusted, so that the lifting plate 4 can effectively drive the cuvette body 5 to move synchronously. The sizes of the two driving wheels are inconsistent, so there will be no impact on the transmission relationship between the two threaded rods 9.

A guide groove for the movable plate 15 is provided at the bottom, and the bottom of the two movable plates 15 are fixedly connected with a clamping plate 17. When the colorimetric cell body 5 needs to be fixed, it is only necessary to pull the clamping plate 17 first. At this time, the clamping plate 17 will drive the movable plate 15 to move synchronously outside the slide bar 14. During the movement of the movable plate 15, the reset spring 16 will be squeezed. At this time, the colorimetric cell body 5 is placed between the two clamping plates 17, and then the clamping plate 17 is released. At this time, the reset spring 16 is reset, driving the movable plate 15 to move synchronously, and the movable plate 15 then drives the clamping plate 17 to move synchronously. At this time, the colorimetric cell body 5 can be effectively fixed and clamped by the clamping plate 17.

When the plug-in rod 24 is out of the guide groove inside the mounting sleeve 20, the mounting sleeve 20 can be pulled out from the outside of the mounting plate 21. At this time, the cleaning sponge 19 can be disassembled. When the cleaning sponge 19 needs to be installed, it is only necessary to first sleeve the mounting sleeve 20 on the outside of the mounting plate 21, and then release the plug-in rod 24. At this time, the resistance spring 25 is reset, driving the plug-in rod 24 to move synchronously. When the plug-in rod 24 is plugged into the guide groove inside the mounting sleeve 20, the mounting sleeve 20 and the mounting plate 21 can be fixed. At this time, the cleaning sponge 19 can be installed.
