[0030] This application will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1 As shown, the liquid level identification device of this application includes a liquid inlet system and a liquid storage device 4; the liquid inlet system includes a liquid inlet 11, a liquid inlet pipe 12 and a liquid suction pump (not shown), the liquid suction pump is connected to the liquid inlet 11 through a pipeline, the liquid inlet 11 is connected to the liquid inlet pipe 12, the liquid inlet 11 is located outside the liquid storage device 4, and the liquid inlet pipe 12 is located inside the liquid storage device 4.

[0032] The liquid inlet pipe 12 is located near the top of the liquid storage device 4, and is flush with the position of the first upper baffle.

[0033] In this application, the suction pump connects an external solution source to the inlet 11 via a pipeline, thereby drawing the solution into the storage device 4. After the suction pump is turned on, the diluted liquid is drawn into the storage device 4.

[0034] This application also includes a liquid level detection module, which includes an upper float 21, a first upper baffle 22, a first lower baffle 23, a float support rod 24, a lower float 25, a second upper baffle 26, and a second lower baffle 27.

[0035] The upper float 21 and lower float 25 have built-in magnets and are respectively set at a preset high position and a preset low position in the liquid storage device 4.

[0036] The float support rod 24 is perpendicular to the inside of the liquid storage device 4 and has a built-in magnetic induction element for identifying the float position.

[0037] Specifically, the first upper baffle 22 and the first lower baffle 23 are fixed to the upper end of the float support rod 24, and the upper float 21 is located between the first upper baffle 22 and the first lower baffle 23. The first upper baffle 22 and the first lower baffle 23 restrict the movement range of the upper float 21.

[0038] Specifically, the second upper baffle 26 and the second lower baffle 27 are fixed to the upper end of the float support rod 24, and the lower float 25 is located between the second upper baffle 26 and the second lower baffle 27. The second upper baffle 26 and the second lower baffle 27 restrict the movement range of the lower float 25.

[0039] This application also includes a liquid dispensing system, which includes a liquid outlet 31 and a liquid dispensing pipe 32 for automatically extracting solution.

[0040] Specifically, the liquid outlet 31 is connected to the liquid outlet pipe 32. The liquid outlet 31 is located outside the liquid storage device 4, and the liquid outlet pipe 32 is located inside the liquid storage device 4. The liquid outlet pipe 32 is parallel to the float support rod 24 and is fixedly connected by a connector. The lower end of the liquid outlet pipe 32 is in contact with the bottom of the liquid storage device 4.

[0041] It should be noted that the bottom of the liquid outlet tube 32 is provided with a notch 33, which has a certain height of at least 5mm to facilitate the extraction of solution. The notch 33 can have various shapes, such as arc, square, rectangle, or irregular shape. In a preferred embodiment of this application, the notch 33 is semi-circular.

[0042] The liquid outlet tube 32 is used to extract liquid after the filling is completed.

[0043] The float in this application is equipped with a magnet. The float support rod 24 senses the position of the float through the magnet, thereby determining the liquid level. When the liquid storage device 4 is empty, the upper float 21 is close to the first lower baffle 23, and the lower float 25 is close to the second lower baffle 27. As liquid is injected, the float positions change. After injection begins, the lower float 25 is close to the first upper baffle 22. The float support rod 24 identifies the position of the float through the magnet in the float, determines that the liquid level has reached the preset low level, and continues injection. When the upper float 21 is close to the first upper baffle 22, the system determines that the liquid level has reached the preset high level, recognizing that the solution has been injected in place. Similarly, by identifying the position of the float, the system can also determine the state of insufficient liquid.

[0044] The liquid level identification device of this application, through the above-described structure and working method, realizes automated control of solution filling and use, improves the efficiency of filling and use, and is particularly suitable for application in immunoblotting analyzers.

[0045] In this application, the start and stop of the liquid suction pump and the liquid outlet pipe are automatically controlled by the feedback signal from the liquid level detection module. The upper float and the lower float correspond to the high and low positions of the liquid storage device, respectively. The magnetic induction element built into the float support rod cooperates with the float magnet to determine the "empty tank", "filling" and "full" states.

[0046] The following is the working principle of this application:

[0047] Injection Phase: After the suction pump starts, the solution is injected into the storage device through the inlet. Initially, when the tank is empty, the upper and lower floats are close to the first and second lower baffles, respectively, and the float support rod detects "insufficient liquid level" through magnetic induction. When the liquid level rises to the preset height of the lower float, the lower float magnet triggers the float support rod sensor, determining that "the liquid level has reached the middle of the injection stage." When the liquid level continues to rise to the preset height of the upper float, the upper float magnet triggers the sensor, the system determines "injection complete," and stops the suction pump.

[0048] Extraction phase: The outlet pipe automatically extracts the solution. As the liquid level drops, the float moves downward accordingly. The float support rod provides real-time feedback on the liquid level through magnetic induction. When the upper and lower floats approach the first and second lower baffles respectively, the system determines that "refilling is required".

[0049] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any non-substantial modifications made to this application using this concept shall be considered an infringement of the scope of protection of this application.
