[0002] With the increasing severity of water pollution, water quality monitoring, as a fundamental aspect of water pollution control, has become increasingly important. Currently, the process of detecting water quality parameters using spectrophotometry generally requires the use of a spectrometer. This spectrometer employs a light source capable of generating multiple wavelengths. Through a series of spectroscopic devices, a specific wavelength of light is produced. After the light passes through the sample being tested, some of it is absorbed. The absorbance value of the sample is calculated, thus converting it into the sample's concentration.

[0003] Spectrometers include single-beam spectrophotometers, double-beam spectrophotometers, and dual-wavelength spectrophotometers. A single-beam spectrophotometer includes a light source, monochromator, absorption cell, phototube, amplifier, and readout display device. A double-beam spectrophotometer has two monochromators and an additional chopper. The absorption cell, also known as a cuvette or colorimetric cup, is highly susceptible to contamination, which significantly affects analytical results. Manual cleaning of the cuvette is necessary after each test and before the next, a cumbersome and time-consuming process that greatly reduces testing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, an absorption cell and spectrometer with automatic cleaning function are proposed to solve the technical problems of cumbersome operation, long time consumption, and reduced cleaning efficiency caused by manual cleaning of absorption cells in existing technologies.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The other two ports of the three-way valve are respectively connected to the water sample pipeline to be tested and the cleaning pipeline.

[0007] The technical solution is further configured such that the drain outlet is connected to the drain pipe, and a pump body is provided on the drain pipe, the water sample pipe to be tested, and the cleaning pipe.

[0008] The technical solution is further configured such that the pool body is a cylindrical structure with an annular notch on its side wall, and the bottom of the cover is embedded inside the notch.

[0009] The technical solution is further configured such that the pressure plate includes an integrally formed first pressure edge, a connecting edge, and a second pressure edge, wherein the first pressure edge and the second pressure edge are parallel and both are perpendicular to the connecting edge, and the first pressure edge and the second pressure edge are located on different sides of the connecting edge.

[0010] The technical solution is further configured such that the first pressing edge is connected to the mounting groove by a fixing bolt, and the connecting edge and the second pressing edge abut against different sides of the ultrasonic generator.

[0011] The technical solution is further configured such that two pressure plates are symmetrically arranged, and a channel for ultrasonic waves to pass through is left between the second pressing edges of the two pressure plates.

[0012] The technical solution is further configured such that there are two fixing bolts, and a limiting ring adapted to the shape of the fixing bolt is fitted on the fixing bolt, and the limiting rings on the two fixing bolts are connected.

Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0022] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0023] According to an embodiment of this utility model, an absorption tank with an automatic cleaning function is provided. Please refer to [link / reference]. Figures 1 to 3 The device includes a detachably connected pool body 100 and a cover 200. The bottom of the cover 200 is provided with a mounting groove recessed towards its top. An ultrasonic generator 300 is installed inside the mounting groove via a pressure plate 400. The bottom surface of the pool body 100 is provided with a water inlet and a water outlet. The water inlet is connected to one port of a three-way valve 600 via a water inlet pipe 500. The other two ports of the three-way valve 600 are respectively connected to the water sample pipeline 700 to be tested and the cleaning pipeline 800.

[0024] Furthermore, an optical window is provided on the side of the pool body 100 to allow light generated by a light source to pass through.

[0025] It should be noted that the three-way valve 600 connects to the water sample pipeline 700 and the cleaning pipeline 800 respectively, allowing the water sample or cleaning water to be introduced into the tank body 100. An ultrasonic generator 300 is installed at the bottom of the cover 200. The ultrasonic generator 300 is used to perform ultrasonic vibration on the water sample or cleaning water inside the absorption tank, improving the detection accuracy and cleaning effect. No manual intervention is required for the cleaning operation, thus improving the cleaning efficiency.

[0026] In the absorption tank with automatic cleaning function in this embodiment, please refer to... Figures 1 to 3The drain outlet is connected to the drain pipe 900, and a pump body is installed on the drain pipe 900, the water sample pipe 700 to be tested, and the cleaning pipe 800.

[0027] Specifically, a first pump body 110 is installed on the water sample pipeline 700, a second pump body 120 is installed on the cleaning pipeline 800, and a third pump body 130 is installed on the drain pipeline 900. In use, the liquid flowing into the pool body 100 can be selected as either the water sample to be tested or cleaning water by controlling the three-way valve 600. When the water sample to be tested needs to be injected into the pool body 100, the three-way valve 600 connects to the water sample pipeline 700, and the water sample flows into the pool body 100 for testing. After testing, the water sample is discharged through the drain pipeline 900. When the pool body 100 needs to be cleaned, the three-way valve 600 connects to the cleaning pipeline 800, and cleaning water flows into the pool body 100, achieving automatic cleaning. After cleaning, the cleaning water is discharged through the drain pipeline 900. This process can be performed automatically periodically or automatically after each measurement.

[0028] In the absorption tank with automatic cleaning function in this embodiment, please refer to... Figures 1 to 3 The pool body 100 is configured as a cylindrical structure with an annular notch on its side wall, and the bottom of the cover 200 is embedded inside the notch.

[0029] Furthermore, the notch is located on the inner surface of the sidewall, and the notch and the top of the sidewall form a stepped structure. Correspondingly, the bottom of the cover 200 is set to a shape that adapts to the stepped structure to improve the connection stability between the two.

[0030] Furthermore, the size of the cover 200 is larger than the size of the pool body 100, that is, the edge of the cover 200 extends to the outside of the pool body 100, which facilitates hand assembly.

[0031] Furthermore, sealing rings are provided on the contact surfaces of the cover 200 and the pool body 100 to prevent the water sample to be tested or the cleaning water from overflowing.

[0032] In the absorption tank with automatic cleaning function in this embodiment, please refer to... Figures 1 to 3 The pressure plate 400 includes an integrally formed first pressure edge 401, a connecting edge 402, and a second pressure edge 403. The first pressure edge 401 and the second pressure edge 403 are parallel and both are perpendicular to the connecting edge 402. The first pressure edge 401 and the second pressure edge 403 are located on different sides of the connecting edge 402.

[0033] Specifically, the first pressing edge 401 and the second pressing edge 403 are respectively set parallel to the cover body 200, the connecting edge 402 is set perpendicular to the cover body 200, and the mounting groove provides installation space for the pressing plate 400 and the ultrasonic generator 300.

[0034] Furthermore, the first pressing edge 401 is connected to the mounting groove by a fixing bolt 140, and the connecting edge 402 and the second pressing edge 403 respectively abut against different sides of the ultrasonic generator 300.

[0035] It should be noted that the fixing bolt 140 connects the cover 200 and the pressure plate 400 into one piece, and the connecting edge 402 is set perpendicular to the second pressure edge 403, providing a space for the ultrasonic generator 300.

[0036] Specifically, two pressure plates 400 are symmetrically arranged, located on opposite sides of the ultrasonic generator 300, clamping the ultrasonic generator 300 from different directions. A channel for ultrasonic waves to pass through is provided between the second pressing edges 403 of the two pressure plates 400. In other embodiments, the pressure plates 400 are configured as a symmetrical structure, with each side including an integrally formed first pressing edge 401, a connecting edge 402, and a second pressing edge 403. The ultrasonic generator 300 is pressed between the second pressing edge 403 and the cover 200, and a window for ultrasonic waves to pass through is provided on the second pressing edge 403.

[0037] Specifically, to protect the sensitive components inside the ultrasonic generator 300 from environmental influences (such as moisture) while ensuring effective transmission and reception of ultrasonic waves, the channel or window is covered with a sound-permeable material. This material has good acoustic transmission properties to minimize obstruction to ultrasonic wave transmission. Preferably, the sound-permeable material can be polyurethane, polyethylene terephthalate, etc.

[0038] In the absorption tank with automatic cleaning function in this embodiment, please refer to... Figures 1 to 3 Two fixing bolts 140 are provided, and a limiting ring 150 adapted to the shape of the fixing bolt 140 is sleeved on it. The limiting rings 150 on the two fixing bolts 140 are connected to each other.

[0039] Furthermore, the limiting ring 150 is provided with a connecting rod 160, and the connecting rods 160 on the two limiting rings 150 are connected by locking bolts. Specifically, the two connecting rods 160 have different widths, that is, one connecting rod can be embedded inside the other connecting rod. The two connecting rods 160 have corresponding through holes, and the locking bolts are embedded in the through holes and locked by nuts, which can prevent the two connecting rods 160 from rotating relative to each other. Since the shape of the limiting ring 150 is adapted to the fixing bolt 140, the fixing bolt 140 can be prevented from loosening, thus improving the stability of the ultrasonic generator 300.

[0040] According to an embodiment of the present invention, a spectrometer is provided, including the absorption cell with automatic cleaning function.
