However, the cleaning solution for cleaning the dispensing needle is installed in the sample analyzer through the liquid storage barrel at present, and because of the tension of the internal space of the sample analyzer, the sample analyzer cannot accommodate more liquid storage barrels, and in general, the sample analyzer only accommodates two liquid storage barrels, and the consumption of the cleaning solution on the liquid storage barrels in the sample analyzer is larger, the insufficient cleaning solution can cause the sample analyzer to be unable to work continuously, and the replacement of the liquid storage barrels in the sample analyzer is also troublesome.
As shown in fig. 1 to 11, according to a first aspect of the present application, there is provided a liquid supply system including a first liquid supply line 100, a second liquid supply line 200, a buffer container 40, a valve assembly, a confluence block 20 and a plurality of external liquid storage barrels 10, wherein the first liquid supply line 100, the valve assembly, the confluence block 20 and the plurality of external liquid storage barrels 10 are all disposed outside a sample analyzer, so that not only is replacement of the external liquid storage barrels 10 facilitated, but also the external liquid storage barrels 10 are conveniently connected into a cleaning assembly 400 of the sample analyzer through the second liquid supply line 200 to ensure sufficient cleaning liquid to supply cleaning of a dispensing needle.
Specifically, the plurality of external liquid storage barrels 10 are used for storing cleaning liquid; the confluence block 20 is used for collecting the liquid on the plurality of external liquid storage barrels 10; a valve assembly is provided on the first liquid supply line for controlling the flow of liquid between each of the external liquid storage tanks 10 and the confluence block 20; the buffer container 40 is used for storing the cleaning liquid transferred from the confluence block 20, so that the sample analyzer can draw the cleaning liquid from the buffer container 40 for cleaning the dispensing needle; the second liquid supply line 200 is connected between the confluence block 20 and the buffer container 40, and the second liquid supply line 200 is provided with a pressure source 50 and a detection unit 60.
Wherein, the pressure source 50 is disposed between the detecting unit 60 and the buffer container 40, the pressure source 50 is used for generating the pressure of the liquid discharged from the external liquid storage barrels 10 to the buffer container 40, and the detecting unit 60 is used for detecting the liquid condition on each external liquid storage barrel 10, so that the valve assembly can be switched according to the liquid condition on each external liquid storage barrel 10 when the external liquid storage barrel 10 discharges liquid to the buffer container 40.
It should be noted that, the dispensing needle includes a sample needle, a reagent needle, a cleaning needle, etc. on the sample analyzer, and when the sample needle, the reagent needle, the cleaning needle complete the actions of sampling or loading, etc., the cleaning process is required to be performed for the next sampling or loading, etc., so as to avoid cross contamination.
After the above technical solution is adopted, when the dispensing needle on the sample analyzer needs to be cleaned, the second liquid supply pipeline 200 transfers the liquid in the buffer container 40 to the cleaning assembly 400 on the sample analyzer for cleaning the dispensing needle. The liquid on the buffer container 40 is transferred from the external liquid storage barrel 10 to the confluence block 20 through the second liquid supply pipeline 200, and the valve assembly is arranged between the confluence block 20 and the external liquid storage barrel 10, so that the external liquid storage barrel 10 can be selected by controlling the closing or opening of the valve assembly, the external liquid storage barrel 10 can be replaced conveniently, and meanwhile, the air in the buffer container 40 is increased and even a large amount of resource waste is caused because the pressure source 50 continuously pumps the cleaning liquid into the external liquid storage barrel 10 which is used up by the cleaning liquid can be avoided.
Therefore, the above-mentioned detecting unit 60 is connected between the pressure source 50 and the confluence block 20, and is used for judging the liquid condition on each external liquid storage barrel 10, if the detecting unit 60 detects that a large amount of cleaning liquid is still stored on the external liquid storage barrel 10 being extracted by the current pressure source 50, the valve assembly controls the first liquid supply pipeline 100 to be communicated with the external liquid storage barrel 10 being extracted by the current pressure source 50 and the confluence block 20; if the detecting unit 60 detects that the cleaning solution on the external liquid storage barrel 10 being drawn by the current pressure source 50 is consumed, the valve assembly cuts off the communication between the first liquid supply pipeline 100 and the external liquid storage barrel 10 being drawn by the current pressure source 50 and the confluence block 20, and opens the communication between the first liquid supply pipeline 100 and the other external liquid storage barrel 10 and the confluence block 20, so that the external liquid storage barrel 10 can continuously confluence the cleaning solution to the confluence block 20 and then transfer the cleaning solution to the buffer container 40 through the second liquid supply pipeline 200.
In addition, the buffer container 40 may be provided outside the sample analyzer or inside the sample analyzer, in order to provide the cleaning solution to the cleaning assembly 400 on the sample analyzer, ensuring continuous operation of the sample analyzer.

Specifically, each external liquid storage barrel 10 is connected with the confluence block 20 through a first liquid supply pipeline 100, each first liquid supply pipeline 100 is provided with the control valve 30 so as to control the connection or disconnection of the external liquid storage barrel 10 and the confluence block 20, the confluence block 20 is connected to the buffer container 40 through a second liquid supply pipeline 200, the pressure source 50 and the detection unit 60 are arranged on the second liquid supply pipeline 200, the number of the pressure source 50 and the detection unit 60 can be reduced, the production cost of a liquid supply system is reduced, the liquid condition on each external liquid storage barrel 10 can be monitored in real time, the mutual switching among the control valves 30 is facilitated, and meanwhile, the external liquid storage barrel 10 consumed by a user is convenient to replace.

In an alternative embodiment, a liquid level detector is disposed within the buffer container 40 and is electrically connected to the pressure source 50, such that the liquid level detector can control the opening or closing of the pressure source 50 according to the level of the liquid on the buffer container 40.
In general, the liquid level detector may employ a common pressure sensor for detecting the level of the cleaning liquid in the buffer container 40, and when the liquid level detector detects that the level of the cleaning liquid in the buffer container 40 is lower than or higher than a preset value, the liquid level detector sends a signal to remind a user or control the pressure source 50 to operate or stop operating. By adopting the liquid level detector to detect the cleaning liquid in the buffer container 40 in real time, the cleaning liquid on the external liquid storage barrel 10 can be continuously loaded into the buffer container 40 under the condition that the cleaning liquid in the buffer container 40 is insufficient, so that the problem that the sample analyzer cannot continuously work due to the insufficient cleaning liquid in the buffer container 40 is avoided.

Specifically, the liquid level detector is a four-segment float switch, the four-segment float switch is all disposed in the buffer container 40, and the four-segment float is used for detecting the relationship between the liquid level height of the cleaning liquid in the buffer container 40 and four heights, wherein the four heights are H1, H2, H3 and H4 respectively.
