[0052] A cartridge mounting seat assembly 1, used for mounting a reagent cartridge 12;

[0053] A first mounting seat assembly 2, arranged on a first side of the cartridge mounting seat assembly 1;

[0054] A second mounting seat assembly 3 is vertically movably disposed on the first mounting seat assembly 2;

[0055] A first light source 4 is disposed on the second mounting seat assembly 3 in a pitch-adjustable manner and is used to emit light to laterally illuminate a first preset position of the reagent cartridge 12;

[0056] A first image collector 5, disposed on the second side of the cartridge mounting seat assembly 1 and used to collect a first liquid surface image of the reagent at a first preset position;

[0057] The controller is connected to the first image collector 5 for communication and can detect a first liquid level of the reagent at a first preset position according to the first liquid level image.

[0058] Specifically, the liquid level detection device also includes a workbench 13, and the cartridge mounting seat assembly 1 includes a cartridge mounting seat 102 arranged on the workbench 13 and a positioning seat 103 detachably arranged on the top of the cartridge mounting seat 102, and the positioning seat 103 is used to install the reagent cartridge 12 and position the reagent cartridge 12; the reagent cartridge 12 in this embodiment is cylindrical, and a plurality of reagent cavities for storing reagents are formed inside the reagent cartridge 12, and the plurality of reagent cavities are distributed circumferentially along the center of the reagent cartridge 12; the first mounting seat assembly 2 includes a mounting base 201 fixed on the workbench 13 and a first mounting column 202 arranged on the mounting base 201; the light energy emitted by the first light source 4 is laterally irradiated to the first preset position of the reagent cartridge 12, so as to detect the liquid level height of the reagent in the plurality of reagent cavities located at the first preset position. If the specifications and dimensions of the reagent cartridge 12 change (the positioning seat 103 can be adaptively replaced), the operator can adaptively adjust the height position of the second mounting seat assembly 3 on the first mounting seat assembly 2 and / or the pitch angle of the first light source 4, so that the installation height and / or pitch angle of the first light source 4 can better adapt to the detection of the reagent liquid level in the reagent cartridge 12 after the specifications and dimensions change, so as to ensure the accuracy of the detection of the reagent liquid level at the first preset position after the specifications and dimensions of the reagent cartridge 12 change.

[0059] Furthermore, after the installation height and / or pitch angle of the first light source 4 are adjusted, the controller controls the first image acquirer 5 (such as a camera) to acquire a first liquid level image of the reagent at the first preset position of the reagent cartridge 12, and then sends the acquired first liquid level image to the controller, which performs image recognition on the first liquid level image and determines the first liquid level height of the reagent at the first preset position based on the result of the image recognition (if there is reagent in multiple reagent chambers at the first preset position, the liquid level heights of the reagent in the multiple reagent chambers are all the first liquid level height).

The above arrangement allows the first plug-in portion 3021 to pivot relative to the first connecting member 301, which is convenient for the operator to adjust the deflection angle of the first light source 4 on the vertical plane according to actual needs, which is beneficial to further enhance the effect of the first light source 4 on irradiating the reagent cartridge 12, and further helps to enhance the practicality of the liquid level detection device and the accuracy of its detection effect.
