An essential oil reflux-type atomizer comprising the following structures: a chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. Oil and gas flow together at the gas and oil nozzles to disperse and atomize the oil in the gas flow. A heater is used to raise the temperature of the oil where it is atomized, either by heating the oil itself or by heating the gas flowing into the oil. Thus, the atomizer can have improved performance, especially with essential oils having high viscosity and molecular weight.

An active substance supply system for an agricultural sprayer has a main liquid circuit which includes a reservoir for a main liquid and permits circulation of the main liquid, where the main liquid circuit includes one or more distribution sections which are each configured to distribute to several dispensing elements a spray liquid to be dispensed, and a feed system which is connected to the main liquid circuit and in which the main liquid is mixed with at least one separately supplied active substance to form a liquid active substance mixture, where the active substance supply system is configured to introduce the active substance mixture into the one or more distribution sections at several places.

A method for monitoring and/or adjusting an active agent concentration in a spray liquid to be deployed via a spray device for agricultural purposes, an active agent and a carrier liquid being fed to a mixing unit of the spray device in order to blend the spray liquid. The method includes: receiving a first property signal including a piece of property information of the blended spray liquid detected using a first sensor unit, to ascertain an actual value of the property information of the spray liquid; receiving a second property signal including the piece of property information of the supplied carrier liquid detected using a second sensor unit of the spray device to ascertain a base value of the property information of the carrier liquid; and outputting an information signal to a display unit and/or a control signal to a delivery unit of the spray device.

A spraying device for deploying liquids for agricultural purposes. The spraying device includes at least one spray nozzle for spraying the liquid and at least one mixing device, which includes at least one mixing chamber, at least one first inflow for a carrier liquid, at least two second inflows for different active agent liquids, and at least one outflow connected to the spray nozzle, connecting to the mixing chamber. It is provided that an actuatable valve is associated with each of the inflows. A device is also provided which actuates the valves during intended use in such a way that a constant volume flow results in the outflow regardless of the actuation of the valves/switching of the inflows.
