In fully automated chemiluminescence immunoassay analyzers, cleaning fluid is commonly used to clean the magnetic beads in the reaction cups. To maintain a stable environment within each reaction cup during cleaning and avoid result deviations caused by temperature changes, a device is needed to stably heat the cleaning fluid. This necessitates a liquid preheating module to heat the cleaning fluid.

[0028] A chemiluminescence immunoassay analyzer includes: the aforementioned liquid preheating module.

[0029] The technical solution of this utility model has the following advantages:

[0030] 1. The liquid preheating module provided by this utility model includes:

[0031] A cleaning pipeline heating plate, wherein a cleaning fluid pipeline is wound around the cleaning pipeline heating plate;

[0032] A heating device is attached to and connected to the heating plate of the cleaning pipeline, and is used to heat the heating plate of the cleaning pipeline to heat the cleaning fluid pipeline;

[0033] The heat-insulating cavity contains the heating plate for the cleaning pipeline and the heating device.

[0034] In this invention, the heating plate and heating element for the cleaning pipeline are placed in the same insulated cavity, ensuring a tight connection between them. The cleaning fluid pipeline is then wound around the heating plate to guarantee efficient heat transfer. This structure allows the heating element to directly heat the cleaning pipeline through the heating plate, improving the heating efficiency of the liquid preheating module, enhancing heating performance, and reducing overall equipment energy consumption. Furthermore, it reduces the pipeline length of the liquid preheating module, shrinking the equipment size and thus lowering system resistance while improving installation performance.

[0035] 2. The liquid preheating module provided by this utility model further includes:

[0036] A substrate heating plate, on which a substrate pipeline is wound and disposed within the insulation cavity; a heating device is disposed between the cleaning pipeline heating plate and the substrate pipeline heating plate;

[0037] The heating device has a thin-film structure; the heating plate of the cleaning pipeline, the heating plate of the substrate pipeline, and the heating device are parallel to each other and closely connected.

[0038] In this invention, a substrate heating plate is also provided within the aforementioned insulation cavity. By configuring the heating device as a thin-film structure and installing it between the cleaning pipeline heating plate and the substrate heating plate, the cleaning pipeline heating plate is heated via one side of the thin-film heating device, while the substrate heating plate is heated via the other side of the thin-film heating device. This structure can further reduce the size of the equipment, prevent heat loss and waste, and improve the heating efficiency of the liquid preheating module. Simultaneously, it also enables simultaneous heating of both the cleaning pipeline heating plate and the substrate heating plate.

[0039] 3. In the liquid preheating module provided by this utility model, the side of the cleaning pipeline heating plate and / or the substrate pipeline heating plate facing the heating device is provided with a receiving groove adapted to the shape of the heating device.

[0040] In this invention, by providing a receiving groove on one or both of the heating plate of the cleaning pipeline and the heating plate of the substrate pipeline, the heating device with the thin film structure can be more tightly fitted to the heating plate of the cleaning pipeline and the heating plate of the substrate pipeline, thus ensuring efficient heat utilization.

[0041] 4. The liquid preheating module provided by this utility model includes a first rib plate for the cleaning fluid pipeline to be wound around on the heating plate of the cleaning pipeline; a limiting member for limiting and fixing the cleaning fluid pipeline is also provided in the radial direction of the first rib plate. The substrate pipeline heating plate also includes a second rib plate for the substrate pipeline to be wound around; a limiting member for limiting and fixing the substrate pipeline is also provided in the radial direction of the second rib plate.

[0042] In this invention, the cleaning fluid pipeline is wound around the first rib of the cleaning pipeline heating plate; or the substrate pipeline is wound around the second rib of the substrate pipeline heating plate. These arrangements effectively ensure more uniform contact between the pipeline and the heating plate, thereby improving the heating effect of the heating plate.

[0043] 5. The liquid preheating module provided by this utility model further includes: a temperature sensor for measuring the heating temperature inside the insulation cavity; and / or a temperature protection switch, which is communicatively connected to the temperature sensor to control the power-on and power-off action of the heating device.

[0044] In this invention, when the temperature detected by the temperature sensor is higher than the set temperature, the heating device stops working; when the temperature detected by the temperature sensor is lower than the set temperature, the heating device starts working. The temperature sensor effectively ensures that the heating device operates within its normal operating range.

[0045] 6. The liquid preheating module provided by this utility model includes an insulation cavity comprising: an insulation side plate and an insulation frame; the insulation side plate and the insulation frame can be made of insulation cotton material as needed, thereby effectively improving the insulation effect of the insulation cavity.

[0046] 7. The liquid preheating module provided by this utility model includes a heat insulation cavity comprising: a heat insulation base, which is disposed at the bottom of the cleaning pipeline heating plate, the heating device and the substrate pipeline heating plate, for fixing the cleaning pipeline heating plate, the heating device and the substrate pipeline heating plate, and isolating the temperature of other equipment in the analyzer.

[0047] In this invention, the heat-insulating base can, at the same time, prevent heat exchange between the outside and the heat-insulating cavity as much as possible, while fixing the heating plate of the cleaning pipeline, the heating device and the heating plate of the substrate pipeline inside the heat-insulating cavity.

[0048] 8. The chemiluminescence immunoassay analyzer provided by this utility model includes a liquid preheating module. Therefore, it possesses all the advantages of a liquid preheating module. Attached Figure Description

[0065] Heating device 2 is attached to and connected to the heating plate 1 of the cleaning pipeline, and is used to heat the heating plate 1 of the cleaning pipeline to heat the cleaning fluid pipeline. The above-mentioned liquid preheating module uses a 24V power supply to power the heating device 2 to reduce the risk of electric shock;

Furthermore, the cleaning pipeline heating plate 1 and the substrate pipeline heating plate 4 are respectively provided with connecting holes, through which pins pass to fix the heating element 2 between the cleaning pipeline heating plate 1 and the substrate pipeline heating plate 4.

[0068] In this embodiment, to ensure a tighter fit between the heating device 2 and the heating plate 1 of the cleaning pipeline and the heating plate 4 of the substrate pipeline, thereby maximizing heat utilization efficiency, the heating plate 1 of the cleaning pipeline and the heating plate 4 of the substrate pipeline are each provided with a receiving groove 5 that is adapted to the shape of the heating device 2 on the side facing the heating device 2. The receiving grooves 5 respectively provided on the heating plate 1 of the cleaning pipeline and the heating plate 4 of the substrate pipeline form a cavity for accommodating the heating device 2.

[0071] A temperature protection switch 7 is communicatively connected to the temperature sensor 6 to control the power-on and power-off action of the heating device 2. When the temperature detected by the temperature sensor 6 is higher than the set temperature, the heating device 2 stops working; when the temperature detected by the temperature sensor 6 is lower than the set temperature, the heating device 2 starts working. The detection data from the temperature sensor 6 is sent to a controller, which uses a PID algorithm to control the operation of the heating device 2 to keep the liquid preheating module near the set temperature.

[0072] The temperature protection switch 7 and the temperature sensor 6 are connected to the heating device 2 via a signal line 11; the heat insulation cavity 3 and the heat insulation base 10 are provided with a through hole 15 for the signal line 11 to pass through.

[0073] In this embodiment, in order to effectively improve the heat preservation effect of the heat preservation cavity 3, see... Figure 6 and Figure 7 The insulation cavity 3 includes: a heat-insulating side plate 8, a heat-insulating frame 9, and a heat-insulating base 10.

[0074] In this embodiment, the contact between the pipes and the heating plate is made more uniform, thereby improving the heating effect of the heating plate. For example... Figure 1 and Figure 2 As shown, the heating plate 1 for the cleaning pipeline is also provided with a first rib 12 for the cleaning fluid pipeline to be wound around; a limiting member 13 for limiting and fixing the cleaning fluid pipeline is also provided in the radial direction of the first rib 12.
