[0022] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0023] like Figure 1-2 As shown, as a fully automatic vitamin high-efficiency liquid path system of the utility model, it includes a modification liquid pool 11, a cleaning liquid pool 12, a bottom liquid pool 13, a diluent pool 14 and a detection cup 50, and multiple bottom liquid pools 13 and detection cups 50 are provided, and the number of bottom liquid pools 13 and detection cups 50 is the same;

[0024] Each bottom liquid pool 13 is connected to the NO inlet 202 on the three-way valve 20 through a pipeline;

[0025] The dilution liquid pool 14 is connected to the branch pipe 141 through a pipeline, and the branch pipe 141 is connected to the NC inlet 201 on the three-way valve 20 through a pipeline;

[0027] The solution in the modification liquid tank 11 and the solution in the cleaning liquid tank 12 are added to the plurality of detection cups 50 separately.

[0028] Specifically, each test cup 50 has different test items and requires different base liquids, so a separate pipeline is required to add liquid. Multiple three-way valves 20 are in a long-closed state, NC inlet 201 is in a closed state, and NO inlet 202 is in an open state. Multiple peristaltic pumps 80 add base liquids to multiple test cups 50 separately.

[0029] The multiple three-way valves 20 are in a long-open state, the NO inlet 202 is in a closed state, the NC inlet 201 is in an open state, and the multiple peristaltic pumps 80 add diluent to the multiple detection cups 50 separately.

The modification liquid is the same, so it can be added through one pipeline. The modification liquid diaphragm pump 21 adds the modification liquid to multiple detection cups 50 at the same time through the first one-inlet four-outlet assembled solenoid valve 30.

[0032] like Figure 4 As shown, the cleaning liquid pool 12 is connected to the cleaning liquid diaphragm pump 22 through a pipeline, and the cleaning liquid diaphragm pump 22 is connected to the one-inlet and five-outlet assembled solenoid valve 40 through a pipeline, and the one-inlet and five-outlet assembled solenoid valve 40 respectively adds liquid to multiple detection cups 50 through pipelines.

[0033] The cleaning liquid is used to clean the test cup and the electrode after each test is completed. The cleaning liquid diaphragm pump 22 and a one-inlet and five-outlet assembled solenoid valve 40 add cleaning liquid to multiple test cups and clean the sampling needles. Therefore, one pipeline can be used to add liquid. The cleaning liquid diaphragm pump 22 passes through the one-inlet and five-outlet assembled solenoid valve 40 to add cleaning liquid to multiple test cups 50 at the same time, and the spring cleaning pool cleans the sampling needles.

[0034] like Figure 1 As shown, multiple detection cups 50 are arranged on the waste liquid pool 60, the waste liquid pool 60 is connected to the second one-input four-outlet assembled solenoid valve 70 through a pipeline, the second one-input four-outlet assembled solenoid valve 70 is connected to the waste liquid pump 23 through a pipeline, and the waste liquid pump 23 is connected to the waste liquid collection bin 15 through a pipeline.

Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
