At present, people are paying more and more attention to how to safely and effectively degrade pesticides to ensure food safety, but the phenomenon of excessive pesticide residues still occurs repeatedly. Although many highly toxic pesticides have been banned, they still pose a great threat due to their high stability and long existence time in the environment. In daily life, the refrigerator is the last storage process before food processing. During this stage, if safe and effective methods can be used to degrade and remove pesticides, the safety of food consumption will be greatly improved.

The input shaft end of the micro water pump 28 is connected to the water tank 27 through a water pipe 213, and the output shaft end of the micro water pump 28 is connected to the water pipe 213, and the end of the water pipe 213 away from the micro water pump 28 is arranged in the electrolytic cell 25. The flow rate of the micro water pump 28 is in the range of 5-100 ml / min, and the specific flow rate of the micro water pump 28 is adjusted according to the degradation efficiency and the spraying amount;

[0030] An electrode degradation device 211 and a water level sensor 29 are installed on the bottom surface of the electrolytic cell 25. The water level sensor 29 is electrically connected to the micro water pump 28 and the atomizing sheet 212, which is convenient for controlling the start and stop cycle of the micro water pump 28 and the atomizing sheet 212. The micro motor, the electrolytic plate, the water level sensor 29 and the atomizing sheet 212 are all connected to the main control board in the refrigerator body 1. When the water level sensor 29 detects that the water level of the electrolytic cell 25 is lower than the preset value, it can send it to the main control board of the refrigerator. The main control board controls the micro motor to increase the flow rate and reduce the atomization rate of the atomizing sheet 212. An atomizing hole 210 is opened at the bottom of the electrolytic cell 25, and an atomizing sheet 212 is installed at the bottom of the atomizing hole 210.

After the water is atomized, it is atomized from the atomizing hole 210 into the refrigerator drawer 3 below. The water level sensor 29 controls the start and stop cycle of the micro water pump 28 and the atomizing sheet 212 by real-time detection of the water level in the electrolytic cell 25. The present invention first catalyzes electrolysis of water through the electrode degradation device 211, and then sprays it out through atomization, thereby improving the removal efficiency of pesticide residues on the surface of fruits and vegetables in the refrigerator drawer 3, and the atomization method can prevent the surface of leafy vegetables from absorbing too much water and rotting.
