A portable misting fan including a body having interconnected upper and lower sections thereby circumferentially defining a passageway with respective open ends therebetween, said upper section comprising an arcuate internal reservoir therein, said internal reservoir having an inlet and at least one outlet, a fan assembly arranged at least partially within said passageway, a sonic disk in communication with said at least one outlet and positioned in front of said fan assembly, and a mounting arm pivotably connected to said body about an axis perpendicularly arranged with respect to said open ends of said passageway, where the sonic disk assembly is designed to selectably atomize and disperse waterthe water communicated from the internal reservoirfrom the sonic disk assembly in a continuous or intermittent manner.

An outdoor misting fan and a cooling device. The outdoor misting fan includes a fan atomization assembly including a atomizer and a lower housing, an installation assembly including a cylinder connected with the lower housing, an elastic clamping piece sleeved outside the cylinder and a guiding member, and a battery located inside the cylinder and electrically connected to the fan atomization assembly. The elastic clamping piece can adapt to various types of water storage bottles, and during assembly, the cylinder is directly placed inside the water storage bottle, which increases the available space for the battery. Users do not need to carry bottle when carrying the outdoor misting fan, as commercially available water bottles can be easily fitted and used as a handle. The internal cylinder not only provides additional space for the battery but also facilitates water extraction, which meet the users' needs for long-term and portable usage.

An atomizer is provided. When the atomizer provided by the invention is used, a fan blows air to a water outlet tube, part of the airflow in the water outlet tube passes through a pressurizing tube to enter a water tank to gradually increase the air pressure in the water tank, and liquid in the water tank is pressed into a water inlet tube under high pressure, flows into a guide tube along the water inlet tube and is sprayed out of the guide tube in a direction away from the fan; after flowing out of the guide tube, the liquid is blown out by the airflow blown from the fan into the water outlet tube on the periphery of the guide tube; and the fan is used for blowing air to the water outlet tube and increasing the pressure in the water tank.

The agricultural sprayer includes a base with two vertical guides fixed thereon and carriages mounted on and capable of traveling along said guides. A ducted fan is turnably mounted on axles between the carriages. The inner surface of the fan duct is equipped with nozzles connected to a liquid container. One of the carriages consists of two parts: the first and the second one, with the second part capable of moving relative to the first one. The first and the second parts of said carriage have a duct-swinging crank-rocker mechanism mounted thereon. Said mechanism is configured for setting the inclination angle of the fan duct and adjusting its oscillation amplitude.

Systems, methods, and non-transitory computer-readable media for controlling a crop sprayer. A system includes one or more perception devices configured to generate perception information, the perception information representing a spray coverage, and processing circuitry configured to cause the system to determine adjusted tuning parameters based on the perception information using a machine learning process, the adjusted tuning parameters being different from current tuning parameters corresponding to the perception information, and control a sprayer based on the adjusted tuning parameters.

An atomizer for aerial spraying and a control method thereof are provided and relate to the technical field of agricultural machinery. The atomizer for aerial spraying includes a rotary cage atomizer, a deflection mechanical arm, a transmission assembly, and a driving assembly. The rotary cage atomizer is connected to the deflection mechanical arm via a first adapter, the deflection mechanical arm is connected to the transmission assembly, the driving assembly drives the transmission assembly, so as to drive the deflection mechanical arm to adjust an angle, the angle of the rotary cage atomizer changes along with the change of the angle of the deflection mechanical arm, and a brushless motor is used to adjust the rotation speed of the rotary cage atomizer. The rotary cage atomizer is provided with a primary atomizing valve core and a secondary atomizing rotary cage.
