Description

Technical Field

[0001] This application relates to the field of sample analyzers, and in particular to a laser-intelligent temperature-controlled sample analyzer. Background Technology

[0002] Sample analyzers are instruments used to detect and analyze the composition, structure, and properties of substances. They are widely used in various fields such as chemistry, biology, environmental science, materials science, medicine, and food, helping researchers and industry understand the specific characteristics of samples, ensure product quality, and conduct scientific research.

[0003] Existing laser sample analyzers typically lack the ability to regulate sample temperature. However, temperature changes can affect the state of the sample, especially the particle dispersion in liquid samples. Increased temperature may lead to increased solubility of certain substances, thereby altering their dispersion in the solution. Conversely, decreased temperature may cause particle aggregation or precipitation, making them inconvenient to use. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a laser intelligent temperature control sample analyzer.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] A laser intelligent temperature-controlled sample analyzer includes a housing assembly. Inside the housing assembly are a laser assembly, a sample assembly, and a temperature control assembly. The temperature control assembly includes a temperature control cavity. A spiral tube is fixedly installed inside the temperature control cavity. One end of the spiral tube is connected to the sample assembly, and the other end of the spiral tube is connected to a mixing tube. The other end of the mixing tube is connected to the laser assembly. Two circulation ports are opened on one side of the temperature control cavity, and the circulation ports are connected to a cooler. A heating rod is fixedly installed in the middle of the inner side of the temperature control cavity. A first temperature sensor is fixedly installed at the top of the inner side of the temperature control cavity. A second temperature sensor is provided between the spiral tube and the mixing tube.

[0007] By adopting the above scheme, a spiral tube is fixedly installed inside the temperature control cavity, which facilitates the filling of the temperature control cavity with a heat-conducting medium. The spiral tube is then subjected to water bath temperature control, thereby regulating the sample temperature inside the spiral tube. One end of the spiral tube is connected to the sample assembly, facilitating the sample assembly to transport the sample to the temperature control assembly for temperature regulation. The other end of the mixing tube is connected to the laser assembly, ensuring uniform dispersion of particles in the liquid and improving the accuracy of the laser assembly in sample detection and analysis. A cooler is connected through a circulation interface, allowing the cooler to cool the heat-conducting medium inside the temperature control cavity, thus achieving temperature control of the sample liquid. The heating rod facilitates the heating of the heat-conducting medium inside the temperature control cavity, thereby achieving temperature control of the sample liquid. The first and second temperature sensors facilitate the monitoring of the temperature of the heat-conducting medium inside the temperature control cavity and the temperature of the sample liquid after temperature regulation, thereby facilitating precise control of the operation of the heating rod and the cooler, and achieving precise temperature control of the sample.

[0008] Furthermore, the housing assembly includes a housing, on the top of which a control panel is fixedly mounted. The control panel is electrically connected to the laser assembly, the sample assembly, and the temperature control assembly.

The power interface allows for easy connection to external power lines to provide power to the device. The data interface facilitates connection to external devices, enabling external devices to use and read the device's detection and analysis structure.

[0010] Furthermore, the laser assembly includes a sample chamber, one end of which has a sample outlet and the other end of which has a sample inlet, the sample inlet being connected to a mixing tube.

[0011] By adopting the above scheme and setting up the sample chamber, it is convenient for the sample to flow through the sample chamber for laser detection and analysis.

[0012] Furthermore, a detector is provided on one side of the sample cavity, and an optical system is provided on the other side of the sample cavity, with a laser generator at the top of one end of the optical system.

[0013] By adopting the above scheme and setting the detector, the optical system can focus the laser emitted by the laser generator through the sample cavity and direct it to the detector. This allows the detector to capture the laser light scattered by the sample, thereby generating analytical data of the sample.

[0014] Furthermore, the sample assembly includes a sample storage chamber, the bottom of which is connected to a sample injection pump.

[0015] By adopting the above scheme and setting up the injection pump, it is convenient to pump out the sample from inside the sample storage chamber.

[0016] Furthermore, the output end of the injection pump is provided with a pumping interface, which is connected to the spiral tube.

[0017] By adopting the above scheme, the pump interface is connected to the spiral tube, which facilitates the pumping of the sample into the spiral tube for temperature regulation.

[0018] Furthermore, a sample inlet is provided at the top of one side of the sample storage chamber, and a first discharge port is provided at the bottom of one side of the sample storage chamber, with a solenoid valve inside the first discharge port.

[0019] By adopting the above scheme, the sample inlet and the first outlet are designed to facilitate the injection of sample liquid into the sample storage chamber for storage, which is convenient for sample detection and analysis. The first outlet facilitates the discharge of sample or cleaning solution from the sample storage chamber.

[0020] Furthermore, the top of the sample storage chamber is connected to a first three-way valve, one side of which is provided with a cleaning port, and the other side of which is connected to a second three-way valve.

[0021] By adopting the above scheme, the first three-way valve facilitates connection to the external cleaning fluid transmission pipeline, enabling backflushing and cleaning of the device's interior. It also works in conjunction with the second three-way valve to control the return of the tested sample liquid to the sample chamber for circulation, which helps maintain good particle dispersion and improves measurement accuracy.

[0022] Furthermore, a second discharge port is provided on one side of the second three-way valve, and the other side of the second three-way valve is connected to the sample outlet. The first discharge port, the second discharge port, the sample inlet port and the cleaning port are all located on the outside of the housing.

[0023] By adopting the above scheme, the setting of the second discharge port facilitates the control of the second three-way valve to discharge the detected liquid from the second discharge port.

[0024] In summary, this application has the following technical effects:

[0025] A spiral tube is fixedly installed inside the temperature control chamber, facilitating the filling of the chamber with a heat-conducting medium. Water bath temperature control of the spiral tube allows for adjustment of the sample temperature inside. One end of the spiral tube connects to the sample assembly, enabling the assembly to transport the sample to the temperature control component for temperature regulation.
