[0019] Working principle: After the water pump 4 is started, water is introduced from the bottom of the buffer tank 1 through the water inlet pipe 6. The sampling hose 2 is inserted below the residual water level in the tank to form a stable pressure state. The peristaltic pump of the detection equipment can maintain a stable pressure state during sampling to avoid pressure fluctuations that impact the peristaltic pump when the water inlet pipe 6 is directly connected to the water inlet of the detection equipment, causing inlet and outlet failures. The drain port 3 is located in the middle of the buffer tank 1. When the peristaltic pump stops running, a certain amount of water will remain in the tank. The pump will be started to replace the residual water during the next test. The liquid level sensor ensures that there is always water in the tank to avoid malfunctions caused by the detection equipment being unable to obtain water samples. When no test sampling is performed, the stirring motor 5 starts regularly to drive the stirring component in the buffer tank 1 to stir the water in the buffer tank 1 to ensure the fluidity of the water. When the preset time is exceeded, the circulation pump 7 starts to pump out the residual water in the buffer tank 1 and transport it through the circulating water tank and then guide it back into the buffer tank 1, forming a water circulation operation, further ensuring the fluidity of the residual water, avoiding the phenomenon of residual water being statically retained for too long to form "stagnant water", and increasing the practicality of the device.

[0020] The buffer tank 1 is mainly used for buffering the sampled water. When selecting it, a conventional choice can be made in the existing technology according to the needs.

[0021] The sampling hose 2 is mainly used to cooperate with the peristaltic pump to introduce the water in the buffer tank 1 into the detection equipment. When selected, the output end of the sampling hose 2 is connected to the sampling equipment, and the input end of the sampling hose 2 is located at the bottom of the buffer tank 1.

[0022] The drain port 3 is mainly used to drain the water in the buffer tank body 1 . When selected, the drain port 3 is located in the middle of one side of the buffer tank body 1 .

[0023] The water pump 4 is mainly used for conveying water into the buffer tank 1 in cooperation with the water inlet pipe 6, and when selected, it can be selected according to the needs in the prior art.

[0024] The stirring motor 5 is mainly used for stirring the residual water in the buffer tank 1 in cooperation with the stirring assembly, and when selected, the stirring assembly is arranged in the buffer tank 1 at the other end of the stirring motor 5.
