Existing drink testing equipment, such as fluorescence detectors, can quickly detect bacterial contamination in drinks, but when used in a canteen environment, students have not received professional training and cannot clean the equipment measuring cups. In addition, for equipment safety reasons, it is not suitable for students to operate directly. Utility Model Content

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0017] Specific implementation examples Figure 1 As shown, the utility model is a beverage detection device, including a shell and a detector and a liquid supply pipeline arranged in the shell, the liquid supply pipeline includes a sample chamber 12 and a flushing tank 13, the sample chamber 12 is connected to the detection tank 14 of the detector by means of a first liquid pump 9, the input port of the sample chamber 12 is arranged outside the shell, the flushing tank 13 is also connected to the detection tank 14 of the detector by means of a second liquid pump 10, and the output end of the second liquid pump 10 is also connected to the sample chamber 12.

[0018] In order to prevent the equipment from being accidentally damaged when placed in public places such as canteens, the utility model adopts the form of arranging a sample bin connected to the outside world in the shell, and the equipment is protected by the shell. The sample bin is connected to the outside for the convenience of users to send drinks into the equipment. After startup, the liquid of the drink to be tested is transported to the detection tank for detection by the detector with the help of the first liquid pump. After the detection is completed, the detection tank is emptied, and distilled water is drawn from the flushing tank by the second liquid pump to flush the sample bin and the detection tank, thereby completing automatic cleaning and meeting the use requirements in public environments such as canteens.

[0019] Further, such as Figure 1 As shown, a first solenoid valve 1 is connected between the first liquid pump 9 and the sample chamber 12, a second solenoid valve 2 is arranged between the first liquid pump 9 and the detection tank 14, a waste liquid circuit is connected between the first liquid pump 9 and the second solenoid valve 2, a third solenoid valve 3 is connected in series on the waste liquid circuit, and the waste liquid circuit is connected to a waste liquid chamber 15.

[0020] When the test tank is filled with liquid, the first solenoid valve and the second solenoid valve are opened, and the third solenoid valve is closed. After the test tank is filled with liquid, the second solenoid valve is closed, the first solenoid valve and the third solenoid valve are opened, and the first liquid pump continues to work to send the remaining beverage liquid into the waste liquid bin. A fifth solenoid valve 5 is also provided between the sample bin 12 and the second liquid pump 10. Subsequently, the fifth solenoid valve is opened and the second liquid pump is started, so that the distilled water as the cleaning liquid enters the sample bin and is flushed to the waste liquid bin along the direction of the first solenoid valve, the first liquid pump, and the third solenoid valve. After the set time is reached, it is considered that the flushing is completed. After the flushing is completed, the second liquid pump is closed, the fifth solenoid valve is closed, the first solenoid valve, the second solenoid valve, and the third solenoid valve are powered off and closed, and the first liquid pump is closed. At this time, distilled water for flushing is retained in the sample bin.

[0021] Furthermore, the output end of the detection tank 14 is connected to the waste liquid tank 15 by means of the third liquid pump 11 , and a sixth solenoid valve 6 is also connected between the third liquid pump 11 and the detection tank 14 .

[0022] When the test is completed, open the sixth solenoid valve and start the third liquid pump to send the residual beverage in the test tank to the waste liquid bin, keep the third liquid pump and the sixth solenoid valve open, open the first solenoid valve, the second solenoid valve and the first liquid pump. Since there is distilled water in the sample bin at this time, the distilled water is sent into the test tank to complete the cleaning of the pipeline from the second solenoid valve to the test tank. Then keep the third liquid pump open, close the second liquid pump, the first solenoid valve and the second solenoid valve, open the fourth solenoid valve and the second liquid pump, and formally rinse the test tank. After completion, close the second liquid pump and the fourth solenoid valve.

[0023] The second liquid pump 10 of the flushing tank 13 is connected to the detection tank 14 via the fourth solenoid valve 4 .

[0024] Furthermore, the detection tank 14 is also connected to a hot air blower 16 , and a seventh solenoid valve 7 is connected in series between the hot air blower 16 and the detection tank 14 .

[0025] The detection tank 14 is also connected to a vent pipe, which is in communication with the detection tank 14 , and an eighth solenoid valve 8 is connected in series to the vent pipe.

[0026] After the test tank is rinsed, in order to avoid bacterial growth, the test tank is dried with a hot air blower. During drying, the vent pipe needs to be opened to discharge moisture. Before the equipment is tested, students are required to pour the beverage into the sample chamber by themselves. After turning on the first liquid pump for a period of time, the third liquid pump is turned on at the same time, that is, the beverage sample to be tested is used for pre-rinsing to prevent the pipeline from contaminating the sample.
