Description

Technical Field

[0001] The utility model relates to a radiation spectrum device with ultrasonic cleaning function, belonging to the technical field of spectrometers. Background Art

[0002] The detection principle of a spectrometer is based on the Lambert-Beer law. A substance's spectrum directly reflects the electronic transitions of its molecules and is directly related to its structure. Different substances have different absorption spectra. The intensity of absorption, in turn, is related to the amount of absorbing material. Therefore, qualitative or quantitative analysis of a substance can be performed based on the specificity of its spectrum and the differences in absorption intensity.

[0003] Traditional spectrometers face numerous challenges when handling turbid samples. Suspended matter and residues easily adhere to translucent components, hindering light penetration and causing distorted test results. Existing solutions rely on regular manual cleaning, which is inefficient, and the use of cleaning agents can lead to secondary contamination of the sample or the environment.

[0004] Under current technology, some advanced spectrometers incorporate automated cleaning systems that utilize spray or immersion methods for cleaning. However, these solutions often require additional cleaning media, increasing costs and failing to ensure complete removal of contaminants. In applications requiring high precision, residual cleaning agents can even interfere with analytical results. Utility Model Content

DETAILED DESCRIPTION

[0024] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0025] See also Figure 1 、 Figure 2 and Figure 3 The embodiment of the present invention provides a through-beam spectroscopy device with ultrasonic cleaning, comprising a transmitting side component 1 and a receiving side component 2, wherein a sample flow cell 3 is connected between the transmitting side component 1 and the receiving side component 2, one side of the sample flow cell 3 is connected to a receiving side light-transmitting lens 4, and the other side of the sample flow cell 3 is connected to a transmitting side light-transmitting lens 5; ultrasonic mounting interfaces 6 are formed on the front and rear sides of the sample flow cell 3, and the ultrasonic mounting interface 6 is connected to an ultrasonic cleaning component 8 through an ultrasonic mounting chuck 7; a sample inlet 9 is formed on the upper side of the sample flow cell 3, and a sample outlet 10 is formed on the lower side of the sample inlet and outlet;

[0026] Among them, the installation direction of the ultrasonic cleaning component 8 is perpendicular to the light path direction between the transmitting side component 1 and the receiving side component 2; the ultrasonic cleaning component 8 is used to ultrasonically clean the receiving side transparent lens 4 and the transmitting side transparent lens 5.

[0027] In this embodiment, the ultrasonic cleaning assembly 8 itself is directly related to cleaning efficiency and the accuracy of spectral analysis. It consists of an ultrasonic generator, a transducer, and an electrical circuit. The ultrasonic generator is responsible for generating a high-frequency electrical signal at a specific frequency, which is converted into mechanical vibrations by the transducer.

[0028] The working principle of the ultrasonic cleaning component 8 is based on the cavitation effect generated by ultrasonic waves in liquids. When the high-frequency electrical signal is converted into high-frequency mechanical vibrations by the ultrasonic generator, this vibration is transmitted to the medium in contact with it, and a large number of tiny bubbles are generated in the liquid. With the action of ultrasonic waves, these bubbles will undergo a rapid expansion and closing process. When the bubbles close, strong micro-jet shock waves will be generated in the surrounding liquid. These micro-jet shock waves have extremely high energy density, which is enough to break up the dirt particles in the sample, thereby separating them from the surface to be analyzed and dispersing them in the solution to achieve a cleaning effect. Since the cleaning medium is the liquid itself in which the sample is located, the introduction of foreign chemical cleaning agents is avoided. It is especially suitable for chemically sensitive or easily contaminated samples, ensuring the objectivity and accuracy of the test results.

[0029] In this embodiment, the emitting side component 1 includes an emitting side outer cover 11, an emitting side shell 12, a light source emitting circuit board 13 and an emitting side light blocking ring 14; the emitting side outer cover 11 is fixedly connected to one side of the emitting side shell 12, and the other side of the emitting side shell 12 is fixedly connected to one side of the sample circulation pool 3, the light source emitting circuit board 13 is located inside the emitting side shell 12, and the emitting side light blocking ring 14 is located between the light source emitting circuit board 13 and the emitting side light-transmitting lens 5; the side of the emitting side outer cover 11 is connected to a power line interface 15, and the end of the emitting side outer cover 11 is connected to a signal line interface 16; emitting side sealing gaskets 17 are provided on both sides of the emitting side light blocking ring 14, and the end of the emitting side shell 12 contacts the emitting side sealing gasket 17 on the side of the emitting side shell 12 close to the emitting side shell 12; an emitting side circulation pool sealing gasket 18 is provided between the emitting side shell 12 and the sample circulation pool 3.

[0030] Specifically, the light source emitting circuit board 13 is used to emit a spectrum, which passes through the detection sample in the sample circulation pool 3 and is received by the receiving side component 2 after the emission spectrum. The optical path can be adjusted by adjusting the light-transmitting material of the emitting side light-transmitting lens 5. There are emission side sealing gaskets 17 on both sides of the emitting side light-transmitting lens 5 to prevent the sample in the sample circulation pool 3 from penetrating into the emitting side housing 12, thereby avoiding damage to the light source emitting circuit board 13. The emission side light-blocking ring 14 can prevent the emission light from leaking out, so that the emission light passes through the emission side light-transmitting lens 5 to enter the sample circulation pool 3. In addition, the emission side circulation pool sealing gasket 18 can prevent water from entering the equipment and affecting the normal operation of the circuit. Among them, the power cord interface 15 is used to install the power cord, and the signal line interface 16 is used to install the signal line bayonet connector. The connectors of the power cord interface 15 and the signal line interface 16 adopt a 12V power supply interface.

[0031] In this embodiment, the receiving side component 2 includes a receiving side outer cover 19, a receiving side shell 20, a light source receiving circuit board 21 and a receiving side light blocking ring 22; the receiving side outer cover 19 is fixedly connected to one side of the receiving side shell 20, and the other side of the receiving side shell 20 is fixedly connected to the other side of the sample circulation pool 3, the light source receiving circuit board 21 is located inside the receiving side shell 20, and the receiving side light blocking ring 22 is located between the light source receiving circuit board 21 and the receiving side light-transmitting lens 4; receiving side sealing gaskets 23 are provided on both sides of the receiving side light blocking ring 22, and the end of the receiving side shell 20 contacts the receiving side sealing gasket 23 on the side of the receiving side shell 20 close to the receiving side shell 20; a receiving side circulation pool sealing gasket 24 is provided between the receiving side shell 20 and the sample circulation pool 3.

[0032] Specifically, the light source receiving circuit board 21 is used to receive the spectrum emitted by the light source emitting circuit board 13. After the emission spectrum, it passes through the detection sample in the sample circulation pool 3 and is received by the receiving side component 2. The optical path can be adjusted by adjusting the translucent material of the receiving side light-transmitting lens 4. There are receiving side sealing gaskets 23 on both sides of the receiving side light-transmitting lens 4 to prevent the sample in the sample circulation pool 3 from penetrating into the receiving side housing 20 and avoid damaging the light source receiving circuit board 21. The receiving side light-blocking ring 22 can prevent the emitted light from leaking out, so that the emitted light passes through the receiving side light-transmitting lens 4 to be accurately received by the light source receiving circuit board 21. In addition, the receiving side circulation pool sealing gasket 24 can prevent water from entering the equipment and affect the normal operation of the circuit.
