Improved hand-pushing sprayer

The invention discloses an improved hand-pushing sprayer and belongs to the field of plant protection equipment. The improved hand-pushing sprayer is characterized in that wheels are arranged at the bottom of a rack; a storage battery pack, a chemical supply box, a controller and a spraying mechanism are arranged on the rack from back to front sequentially; the storage battery pack is connected with the controller; the spraying mechanism comprises an air duct, a fan, a spray nozzle and a high-pressure pump; the fan is arranged in the air duct, an air inlet and an air outlet are formed in two ends of the air duct, and the spray nozzle is arranged at the air outlet; the high-pressure pump is connected between the chemical supply box and the spray nozzle; the high-pressure pump and the fan are electrically connected with the storage battery pack; a rotatable flow disturbance device is mounted in the air duct and located in front of the fan. Wind force generated by the fan is disturbed by the flow disturbance device, so that wind force at the air outlet of the air duct keeps uniform, the spraying distances are consistent, the overall spraying coverage range is enlarged, and the spraying efficiency and effect are improved.
