In the process of testing, the sensor module is used for continuously detecting the weight change, the temperature change and the liquid level change in the container, and in the process, if the liquid level is detected to reach 330ml from the bottom surface of the test container, the weight change of the test container is judged once, if the weight change is more than 85g, the excessive foaming is indicated, and if the weight change is less than 75g, the insufficient foaming is indicated. In addition, the temperature change in the test process can be monitored, and if the highest temperature of the test container is lower than 50 ℃ in 5-20S of the foaming process, the foaming temperature is too low; if the highest temperature of the test vessel is higher than 70 ℃ within 5-30S of the foaming process, the foaming temperature is too high.

In some embodiments, the S4 comprises: s41: receiving milk foam quality evaluation results output by the image recognition unit in multiple tests, taking the milk foam quality evaluation results as dependent variables, taking the position of a steam pipe of the coffee machine as independent variables, taking the optimal milk foam quality evaluation results as targets, and optimizing the position of the steam pipe of the coffee machine according to a regression algorithm; s42: inputting the optimized result of the steam pipe position of the coffee machine into the power module, adjusting the position of the test container, enabling the steam pipe of the coffee machine to reach the optimized position, and repeating the test for the coffee machine for a plurality of times.
Specifically, steps S1-S3 of the present solution are a single test procedure, in the single test, the position of the steam tube of the coffee machine is not limited, but because the position of the steam tube of the coffee machine is an important factor affecting the milk foam quality, in order to ensure the test result of the coffee machine, the position needs to be continuously adjusted, so step S4 of the present solution can adjust the position of the steam tube of the coffee machine in the test container according to the detection result of the quality detection module until the best detection quality can be generated, i.e. the space coordinates of the steam tube of the coffee machine can be found, and then the coordinates are determined by using the positioning module, thereby ensuring that in step S5, the milk foam effect of the coffee machine is repeatedly tested.
