The experimental area is provided with a bracket set and a cavity 12 which is sunken downwards. The bracket set is fixedly provided with a water receiving container 13 and a multi-point liquid level sensor 14, the multi-point liquid level sensor 14 extends into the water receiving container 13, the lower end of the water receiving container 13 is provided with an electric valve 15 with adjustable switching degree, and the multi-point liquid level sensor 14 and the electric valve 15 are electrically connected with the controller. This embodiment has an advantage of improving the accuracy of the timing as compared with other overflow devices. The standard requirement of the overflow test is that the rated capacity of the overflow volume of the container is 0.25L or 15%, the larger of the two is required to be continuously filled into the container within 1min, and the timing mode of the existing partially improved overflow equipment is as follows: the water injection pipe is the water injection at first, control system just begins the timing of a minute, but it also needs time to detect the delivery port that solution arrived the water injection pipe from the water tank, this has just led to the error in a time, what current overflow equipment adopted in addition sets up the measuring pump between water tank and water injection pipe, set for the excessive water volume through the measuring pump, but the air in measuring pump and the water injection pipe can cause the error of excessive water volume, actual excessive water volume is less than the excessive water volume of settlement. In this embodiment, a linear correspondence relationship is established between the volumes of the water receiving container 13, the heights of the multi-point liquid level sensor 14, and the opening/closing degrees of the electric valve 15, that is, a required water overflowing amount (that is, a certain volume of the water receiving container 13) is selected by the control panel, the controller converts the required water overflowing amount into the sensing height of the multi-point liquid level sensor 14, and meanwhile, in order to inject the overflowing amount into the sample within one minute, a larger water overflowing amount corresponds to a larger opening/closing degree of the electric valve 15, so that when the multi-point liquid level sensor 14 sends a signal that the target water level has been reached to the controller, the controller controls the water injection valve to stop injecting water, and further controls the opening/closing degree of the electric valve 15 and starts timing for one minute. The overflow amount of the present embodiment is determined by the multi-point liquid level sensor 14, and is not affected by the air in the metering pump and the water injection pipe 10, and the one-minute timing is started when the electric valve 15 is opened, so that the time error and the overflow amount in the solution filling process are reduced, and therefore, the accuracy of the overflow test implemented by the present embodiment is higher.
