The dripper 4 and the soap film blowing nozzle 5 are oppositely arranged, so that liquid drops of the first reaction liquid can drop on a soap film of the second reaction liquid. When the liquid drops are dripped into the soap film under the action of gravity, the first reaction liquid and the second reaction liquid can be quickly mixed and react, and the formed reaction product flows down to the bottom surface of the constant temperature box 1 along the outer wall of the soap film blowing nozzle 5 or falls to the bottom surface of the constant temperature box 1 along with the broken and falling soap film, so that the aim of collecting the reaction product is fulfilled.

The photoelectric detection component is arranged towards the upper part of the soap film blowing nozzle 5 and is used for detecting whether a new reaction product is generated after the first reaction liquid drops on the soap film of the second reaction liquid; specifically, when a new reaction product is generated, the light absorption rate of the surface of the soap film changes, and when the change of the light absorption rate is detected by the photoelectric detection component, the generation of the new reaction product can be judged. When the photoelectric detection component detects the reaction product, a signal is sent to the control circuit, and the control circuit starts the blowing fan 6 to blow off the soap film.
