Technical Field

[0001] The present application relates to the technical field of spectral analysis equipment, and in particular to a cuvette ultrasonic cleaning device. Background Art

[0002] Cuvettes are widely used in laboratories in research fields such as spectral analysis. Due to frequent use, cuvettes are prone to contamination and dirt accumulation, so they need to be cleaned regularly. The cleaning method using a test tube brush is not only time-consuming and labor-intensive, but also difficult to clean thoroughly and easily causes cross contamination. Utility Model Content

[0003] In order to thoroughly clean the cuvette while avoiding cross contamination, the present application provides a cuvette ultrasonic cleaning device.

[0004] The present application provides a cuvette ultrasonic cleaning device that adopts the following technical solution:

[0005] A cuvette ultrasonic cleaning device comprises a box body; an ultrasonic pulse generator, wherein the ultrasonic pulse generator is arranged in the box body, an ultrasonic probe is arranged at the output end of the ultrasonic pulse generator, and the ultrasonic probe passes through the box body.

[0006] By adopting the above technical solution, the box body is easy for the staff to hold, and the ultrasonic probe is inserted into the cuvette filled with cleaning liquid. The ultrasonic probe is used to emit ultrasonic waves through an ultrasonic pulse generator to subject the cuvette to ultrasonic cleaning to remove pollution and dirt on the cuvette.

[0007] Optionally, a mounting groove for mounting a cuvette is provided on a side of the box body close to the ultrasonic probe.

[0008] By adopting the above technical solution, the cuvette can be positioned by utilizing the mounting groove, thereby ensuring that the ultrasonic probe does not touch the inner wall of the cuvette when extending into the cuvette.

[0009] Optionally, the mounting groove is configured as a U-shaped structure, and an opening of the U-shaped structure is disposed toward the ultrasonic probe.

[0010] By adopting the above technical solution, the U-shaped structure can protect the cuvette, and the left side can facilitate the staff to observe the internal state of the cuvette.

[0011] Optionally, a rubber layer is provided on the opening side of the U-shaped structure.

[0012] By adopting the above technical solution, the rubber layer can increase the friction between the mounting groove and the cuvette to prevent the cuvette from falling off the mounting groove. On the other hand, during the cleaning process, ultrasonic waves will generate vibrations when they are transmitted to the inner wall of the cuvette through the cleaning liquid. The rubber layer can reduce the slight collisions between the cuvette and the mounting groove caused by the vibrations, thereby extending the service life of the cuvette.

[0013] Optionally, a battery compartment is provided on the inner wall of the box body, one side of the battery compartment is communicated with the outer side of the box body, the battery compartment is electrically connected to the ultrasonic pulse generator, and the battery compartment is used to install batteries.

[0014] By adopting the above technical solution, the battery compartment can be used to provide the ultrasonic pulse generator with energy for emitting ultrasonic waves, and it is also convenient to replace the battery in the battery compartment.

[0015] Optionally, the box body is provided with a battery cover that matches the battery compartment.

[0016] By adopting the above technical solution, the battery in the battery compartment can be protected by the battery cover.

[0017] Optionally, the box body is also provided with a cleaning liquid inlet and a cleaning liquid outlet, the cleaning liquid outlet is arranged on one side of the ultrasonic probe, a cleaning liquid pipeline connecting the cleaning liquid inlet and the cleaning liquid outlet is provided in the box body, a cleaning liquid pump is provided on the cleaning liquid pipeline, and the cleaning liquid pump is electrically connected to the battery compartment.

[0018] By adopting the above technical solution, the cleaning liquid pipeline and the cleaning liquid pump can be used to inject cleaning liquid into the cuvette installed on the installation slot, so that the staff does not need to fill the cuvette with cleaning liquid in advance and then install the cuvette filled with cleaning liquid on the installation slot, thereby avoiding pollution caused by spillage of cleaning liquid during the installation process.

[0019] Optionally, the box body is also provided with a waste liquid inlet and a waste liquid outlet, the waste liquid inlet is arranged on the side of the ultrasonic probe away from the cleaning liquid outlet, the box body is provided with a waste liquid pipeline connecting the waste liquid inlet and the waste liquid outlet, the waste liquid pipeline is provided with a waste liquid pump, and the waste liquid pump is electrically connected to the battery compartment.

[0020] By adopting the above technical solution, the waste liquid pipeline and the waste liquid pump can be used to extract the waste liquid from the cuvette installed on the mounting slot, so that the staff can extract the waste liquid from the cuvette without removing the cuvette from the mounting slot, thereby avoiding pollution caused by spillage of waste liquid during the disassembly process. On the other hand, when the cuvette is seriously contaminated and one cleaning cannot completely clean the cuvette, the cleaning liquid pipeline and the cleaning liquid pump can be used to perform a second cleaning on the cuvette without removing the cuvette from the mounting slot.

[0021] Optionally, anti-sealing gaps are provided at the cleaning liquid outlet and the waste liquid inlet.

[0022] By adopting the above technical solution and utilizing the anti-sealing notch, it is possible to prevent the bottom wall of the cuvette from clogging the cleaning liquid outlet and the waste liquid inlet, thereby causing an increase in the pressure in the tube and thus causing an accident.

[0023] Optionally, a control component is provided inside the box body, and an operation screen is provided outside the box body, and the control component is simultaneously connected to the operation screen, the ultrasonic pulse generator, the cleaning liquid pump and the waste liquid pump signal.

[0024] By adopting the above technical solution, the control component can be used to control the reception of the staff's operation signal transmitted from the operation screen, and feed back the operation signal to the ultrasonic pulse generator, the cleaning liquid pump and the waste liquid pump, thereby controlling the start and stop and operating parameters of the ultrasonic pulse generator, the cleaning liquid pump and the waste liquid pump.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Ultrasonic cleaning can be used to clean the cuvette. The ultrasonic cleaning effect is strong and uniform, ensuring the consistency of the cleaning effect. At the same time, the ultrasonic probe that transmits ultrasonic waves is difficult to be contaminated by pollutants cleaned from the cuvette, which can reduce the risk of cross contamination;

[0027] 2. Able to inject cleaning liquid into the cuvette and also extract waste liquid from the cuvette;

[0028] 3. Ability to control cleaning parameters. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The embodiment of the present application discloses a cuvette ultrasonic cleaning device.

[0035] like Figure 1 As shown, the cuvette ultrasonic cleaning device includes a box body 1, an ultrasonic pulse generator is arranged in the box body 1, an ultrasonic probe 3 is arranged at the output end of the ultrasonic pulse generator, and the ultrasonic probe 3 penetrates the box body 1. During the cleaning process, the staff can hold the box body 1, extend the ultrasonic probe 3 into the cuvette filled with cleaning liquid, and use the ultrasonic probe 3 to emit ultrasonic waves through the ultrasonic pulse generator to make the cuvette be cleaned by ultrasonic waves, thereby removing the pollution and dirt on the cuvette.

[0036] like Figure 1 As shown, in order to prevent the ultrasonic probe 3 from touching the inner wall of the cuvette during cleaning or inserting the ultrasonic probe 3 into the cuvette, a mounting groove 4 for mounting the cuvette may be provided on one side of the box body 1 close to the ultrasonic probe 3. The mounting groove 4 can guide and position the cuvette, and can ensure that the ultrasonic probe 3 will not contact the inner wall of the cuvette when the staff inserts the ultrasonic probe 3 into the cuvette, and can also ensure that the positions of the cuvette and the box body 1 are relatively fixed during the cleaning process.

[0037] The mounting groove 4 can be constructed as a rectangular structure or a U-shaped structure. The rectangular structure can provide comprehensive protection for the cuvette, and the side left by the U-shaped structure can facilitate the staff to observe the internal state of the cuvette.

[0038] like Figure 1 As shown, the mounting groove 4 in this embodiment is configured as a U-shaped structure, and the opening of the U-shaped structure is arranged toward the ultrasonic probe 3 , so that the ultrasonic probe 3 can smoothly extend into the cuvette guided through the mounting groove 4 .

[0039] In order to increase the friction between the mounting groove 4 and the cuvette and prevent the cuvette from falling off the mounting groove 4, a rubber layer may be provided on the opening side of the mounting groove 4 of the U-shaped structure. On the other hand, during the cleaning process, when ultrasonic waves propagate in the cleaning liquid to the inner wall of the cuvette, vibrations will be generated, and the rubber layer can effectively reduce the tiny collisions between the cuvette and the mounting groove 4 caused by the vibration, thereby extending the service life of the cuvette.

[0040] like Figure 2 and Figure 3 As shown, in order to provide power to the ultrasonic pulse generator, the inner wall of the box body 1 can be provided with a battery compartment 5 for installing batteries, one side of the battery compartment 5 is connected to the outside of the box body 1, and a battery cover 6 is provided on the connecting side of the battery compartment 5 and the outside of the box body 1, and the battery compartment 5 is electrically connected to the ultrasonic pulse generator.

[0041] The battery compartment 5 with batteries installed can provide energy for emitting ultrasonic waves to the ultrasonic pulse generator, and the battery cover 6 can protect the batteries in the battery compartment 5 and also make it convenient for staff to replace the batteries in the battery compartment 5.

[0042] like Figure 1 and Figure 3 As shown, the box body 1 may also be provided with a cleaning liquid inlet 7, a cleaning liquid outlet 8, a waste liquid inlet 12 and a waste liquid outlet 11. The cleaning liquid outlet 8 and the waste liquid inlet 12 are respectively provided on both sides of the ultrasonic probe 3, and the cleaning liquid outlet 8 and the waste liquid inlet 12 are both located on the same side of the mounting groove 4. In this embodiment, the cleaning liquid inlet 7 and the waste liquid outlet 11 are provided on the side of the box body 1 away from the mounting groove 4, and the cleaning liquid inlet 7 and the waste liquid outlet 11 can be used as long as they can avoid affecting the cuvette, and the present application does not impose any restrictions on the cleaning liquid inlet 7 and the waste liquid outlet 11.

[0043] like Figure 3 As shown, a cleaning liquid pipeline 9 connecting the cleaning liquid inlet 7 and the cleaning liquid outlet 8, and a waste liquid pipeline 13 connecting the waste liquid inlet 12 and the waste liquid outlet 11 are provided in the box body 1.

[0044] A cleaning liquid pump 10 is provided on the cleaning liquid pipeline 9, and the cleaning liquid pump 10 is electrically connected to the battery compartment 5, and is used to pump the cleaning liquid from the cleaning liquid inlet 7 to the cleaning liquid outlet 8, so as to provide cleaning liquid to the cuvette installed in the mounting groove 4, so that the staff does not need to fill the cuvette with cleaning liquid in advance and then install the cuvette filled with cleaning liquid in the mounting groove 4, thereby avoiding pollution caused by spillage of cleaning liquid during the installation process.

[0045] A waste liquid pump 14 is provided on the waste liquid pipeline 13, and the waste liquid pump 14 is electrically connected to the battery compartment 5, and is used to pump the waste liquid from the waste liquid inlet 12 to the waste liquid outlet 11, so as to discharge the waste liquid from the cuvette installed at the mounting slot 4, so that the staff can extract the waste liquid from the cuvette without removing the cuvette from the mounting slot 4, thereby avoiding the waste liquid from spilling and causing pollution during the disassembly process. On the other hand, when the cuvette is seriously contaminated and a single cleaning cannot achieve complete cleaning, the cleaning liquid pipeline 9 and the cleaning liquid pump 10 can be combined to achieve a secondary cleaning of the cuvette without removing the cuvette from the mounting slot 4.

[0046] like Figure 1 and Figure 3 As shown, in order to prevent the cleaning liquid outlet 8 and the waste liquid inlet 12 from being blocked by the bottom wall of the cuvette, thereby increasing the pressure in the tube and causing an accident, an anti-sealing notch 15 is provided at the cleaning liquid outlet 8 and the waste liquid inlet 12.

[0047] like Figure 1 As shown, in order to control the cleaning device, a control component (not shown in the figure) is provided in the box body 1, and an operation screen 16 is provided outside the box body 1. The control component is simultaneously connected to the operation screen 16, the ultrasonic pulse generator, the cleaning liquid pump 10 and the waste liquid pump 14 by signals. The control component can be a single-chip microcomputer or a PLC controller. In this embodiment, the control component is a single-chip microcomputer.

[0048] The control component can be used to control the reception of the staff's operation signal transmitted from the operation screen 16, and feed back the operation signal to the ultrasonic pulse generator, the cleaning liquid pump 10 and the waste liquid pump 14, thereby controlling the start and stop of the ultrasonic pulse generator, the cleaning liquid pump 10 and the waste liquid pump 14, as well as operating parameters such as the ultrasonic intensity emitted by the ultrasonic pulse generator, the flow rate and head of the cleaning liquid pump 10, and the flow rate and head of the waste liquid pump 14.

[0049] The implementation principle of the ultrasonic cleaning device for a cuvette in the embodiment of the present application is as follows:

[0050] Install the cuvette into the installation slot 4.

[0051] The operation screen 16 is used to control the cleaning liquid pump 10 to inject the cleaning liquid into the cuvette through the cleaning liquid pipeline 9, and the injection is stopped after the cleaning liquid fills the cuvette.

[0052] The operation screen 16 is used to control the start of the ultrasonic pulse generator and observe the turbidity of the cleaning solution in the cuvette.

[0053] If it is determined that a single cleaning cannot completely clean the cuvette based on the turbidity, the staff can use the operation screen 16 to control the ultrasonic pulse generator to stop after cleaning continues for a period of time, and use the operation screen 16 to control the waste liquid pump 14 to discharge the waste liquid from the cuvette through the waste liquid pipeline 13. After most of the waste liquid is discharged, the discharge is stopped, and the operation screen 16 is used to control the cleaning liquid pump 10 to inject cleaning liquid into the cuvette through the cleaning liquid pipeline 9. Then, the operation screen 16 is used to control the ultrasonic pulse generator to start, clean the cuvette again, and observe the turbidity of the cleaning liquid in the cuvette.

[0054] If it is judged based on the turbidity level that a single wash can almost clean the cuvette, the staff can use the operation screen 16 to control the waste liquid pump 14 to discharge the waste liquid from the cuvette through the waste liquid pipeline 13, and at the same time use the cleaning liquid pump 10 to replenish the cleaning liquid into the cuvette through the cleaning liquid pipeline 9 to clean the cuvette and observe the turbidity of the cleaning liquid in the cuvette.

[0055] If it is determined that the cuvette can be cleaned by a single cleaning according to the degree of turbidity, the staff can use the operation screen 16 to control the ultrasonic pulse generator to stop after the cleaning continues for a period of time, and use the operation screen 16 to control the waste liquid pump 14 to discharge the waste liquid from the cuvette through the waste liquid pipeline 13, and stop discharging the liquid after most of the waste liquid is discharged. Then, the cleaning liquid pump is used to inject cleaning liquid into the cuvette through the cleaning liquid pipeline 9 to dilute the remaining waste liquid, and the waste liquid pump 14 is used again to discharge the waste liquid from the cuvette through the waste liquid pipeline 13.

[0056] Finally, the cuvette is removed from the mounting slot 4 to complete the cleaning.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
