Spraying device for liquid means of chemical treatment with replaceable liquid subsystem and spraying systems on the basis thereof

A liquid subsystem for use in a spraying device mounted on an unmanned vehicle, the liquid subsystem comprising a reservoir, made in the form of a bag, provided with an outlet channel, and at least one liquid hose, connecting to the reservoir, and provided with a lock valve,

• wherein the liquid subsystem is designed as a separable single unit and entirely replaceable device,
• wherein the liquid subsystem comprises a manifold with one or more outlet ports, which connects the at least one liquid hose to the reservoir via a manifold channel from the manifold to an outlet channel of the reservoir,
• wherein each liquid hose at one end is hermetically connected to one of the outlet ports of the manifold, and at the other end is provided with said lock valve, which is closed in a disconnected state, sealing the internal volume of a liquid to be sprayed with the liquid subsystem,
• wherein said liquid subsystem further comprises either one central or several individual pumping chambers of one or more liquid pump, wherein the pumping chambers are integrated into said liquid subsystem to be replaced together with it and are deformable, designed to be inserted into the corresponding liquid pump of the spraying device, of which the liquid subsystem is a replaceable part,
• wherein:
• in a presence of a single central pumping chamber of each liquid pump, the manifold channel is equipped therewith, or
• in a presence of several individual pumping chambers of each liquid pump, each liquid hose, designed for connecting with an appropriate spraying unit, is equipped with said individual pumping chamber,
• wherein said liquid subsystem further comprises a contactless tag, made as a barcode, two-dimensional code or as a contactless radio frequency tag,
• wherein the contactless tag contains read-only information comprising one or more of a unique identifier of the liquid subsystem, a date of manufacture, a warranty expiry date, a designation of compatibility with various liquids, a designation of maximum operating pressure, or a number of provisioned cycles of use,
• wherein the contactless tag further comprises variable indicators of the liquid subsystem, and
• wherein the variable indicators comprise one or more of an identifier of the used liquid type, impermeability status of the liquid subsystem, or a counter for the cycles of use.
