Abstract
The invention relates to a fresh product oxygen-protecting device for a refrigerator, comprising a power input interface, a working indicating circuit, a timing circuit, a fan driving and interface circuit, an electronic switch circuit, an oscillation and transformation circuit, a 12-fold voltage rectification circuit, a discharging protection circuit and a discharging device that are connected in sequence. All circuits and devices are integrated on a printed circuit board (PCB) with the area of 5.5cmx4.25cm. The fresh product oxygen-protecting device occupies small area, has small size and is convenient to place in a fresh product box; the discharging device has simple structure and high ozone generation efficiency; the power of the whole device during operation is lower than 5Watt with little energy consumption; the whole device has extremely low cost, thereby being suitable for promotion and use.
Description
technical field [0001] The invention relates to a circuit control device, in particular to a fruit and vegetable oxygen protection device for a refrigerator. Background technique [0002] At present, the situation of residual pesticides and chemical fertilizers in agricultural products worldwide is becoming more and more serious. These residues are mainly organic phosphorus and nitrate. Taking my country as an example, in recent years, poisoning accidents caused by pesticide and other residues in fruits and vegetables have occurred frequently, and the toxic accumulation of residues also poses a serious threat to the health of consumers, which has attracted people's attention. How to make people eat "safe" fruits and vegetables has become a major concern of the whole society. In addition, the loss of fruits and vegetables due to improper fresh-keeping and rot is also very large. The annual loss of fruits and vegetables in my country reaches 80 million tons. [0003] At pres...
