[0003] Traditional manual pesticide spraying method has been difficult to meet the needs of modern agriculture. On the one hand, manual operation with a backpack sprayer consumes a lot of physical strength and has low efficiency. It takes a long time to spray pesticides in large greenhouses, and it is easy to miss the best opportunity for pest control. On the other hand, manual operation cannot accurately control the spraying strength and range, resulting in uneven distribution of pesticide solution and affecting the control effect. In addition, the atomized pesticide solution forms high-concentration aerosol in the poor air flow environment in the greenhouse, which can cause chronic respiratory system damage after long-term exposure (according to the WHO research report, the probability of asthma in agricultural workers exposed to pesticides without protection increases by 2.3 times). (4) The barrier efficiency of traditional protective equipment (such as ordinary masks and rubber gloves) for nano-sized pesticide particles and volatile organic compounds is less than 60%, which cannot effectively reduce the risk of occupational exposure.
