The present invention relates to a portable spraying device (1) for discharging a fluid, in particular an agricultural formulation, having a container (2) for holding the fluid, a pump (15), which is in fluid connection with the container (2), for pumping the fluid out of the container (2), a spray gun (21), which comprises a spray opening (27) and an electrically controllable application valve (20) for opening and closing a passage to the spray opening (27), an application line (17), which establishes a fluid connection between the pump (15) and the spray gun (21). The spraying device (1) according to the invention is distinguished by a pressure sensor (19), which is arranged in the application line (17), for detecting the fluid pressure in the application line (17), and an electric control device (28), which is coupled to the application valve (20) and the pressure sensor (19) in terms of data transmission, by means of which device an electric control signal for opening the application valve (20) for a certain predetermined time interval and for closing the application valve (20) on expiry of the time interval can be produced in accordance with the fluid pressure detected by means of the pressure sensor (19), with the result that a defined volume of the fluid is discharged via the spray opening (27).

The present invention relates to the application of plant protection agents, fertilisers and/or pesticides by means of a (preferably portable) sprayer or a small appliance (such as, for example, a bicycle tyre sealant injector). The present invention relates to a monitoring module with which existing sprayers can be equipped in order to control, track and/or document the spraying process. The present invention further relates to a method, a system and a computer program product for monitoring spraying processes.

The present invention discloses a device for controlling the application of insecticides for indoor residual spraying using a sprayer comprising a lance with a spray nozzle, a distance sensor configured to measure the distance between the spray nozzle and the surface being sprayed, an indicator of the distance measured by said sensor, and an indicator of the spraying rate and means of attachment to the sprayer lance and a pipe which allows the insecticide to pass through, and in that the indicator of the distance measured comprises a luminous device which changes colour according to the distance measured by said sensor; a method of applying insecticides for indoor residual spraying by the use thereof, the use thereof to control the application of insecticides and a sprayer which comprises a control device according to the present invention.

A sprayer includes a spray nozzle, a blower and a sprayer housing. The sprayer housing is configured to contain a liquid. The spray nozzle and the sprayer housing are connected. The spray nozzle is configured to spray the liquid out from the sprayer housing. The blower is fixedly connected with the spray nozzle, and the spray nozzle is connected to the sprayer housing through the blower. The blower is rotatable with respect to the sprayer housing so as to adjust the angle of the blower with respect to the sprayer housing, thereby enabling the angle of the spray nozzle to be adjusted with respect to the sprayer housing. The angle of the spray nozzle with respect to the sprayer housing is adjustable, so the spray nozzle is capable of ejecting the liquid at different angles with respect to the sprayer housing without moving the sprayer.

A ready-to-use sprayer comprises a container defining an interior compartment for containing a liquid product and having a pin receiver located near the rear portion and an opening located near the front portion, a housing having a main chamber and a grip portion, a nozzle in selective fluid communication with the outlet of the fluid chamber, a pivot switch on the exterior of the housing for selecting a fluid flow condition for the main chamber, and the housing being coupled to the container at the container opening and the pin receiver.

An electrically powered, portable fluid dispenser that includes a main housing and extendable wand that when used in conjunction with an electric motor, a self-feeding tentacle pumping spinning element, tentacle feed tube, and focusable vibrating backstops, is able to pump, atomize, and dispense, low and high viscosity fluid with controlled directionality and droplet size.

A blower spray device is provided having a housing which comprises an electrically driven blower and a spray nozzle, and having a liquid supply line opening into the spray nozzle. The housing has a funnel-shaped intake channel and a tubular blow-out channel, and an electrical valve is provided in the liquid supply line to activate and deactivate the liquid supply to the spray nozzle. An electronic controller having a regulating unit for the electric blower is further provided to adjust the air flow velocity.

Disclosed herein is a hydrolopper system comprising a herbicide reservoir and pump coupled using a supply line to a hydrolopper tool. Herbicide inside the herbicide reservoir is pumped through the supply line to a first spray head positioned at a distal end of the hydrolopper tool. The hydrolopper tool comprises a blade arm opposed to a landing arm extending from a from a first drive arm and a second drive arm. Closing of the drive arms causes consequent closure between a cutting jaws portion for cutting of vegetation. In some forms, the feedline travels through a cannula of a drive arm, whereas in other forms, the feedline is disposed on the outside of a drive arm. Herbicidal flow rate is controlled by a flow control valve.

A powered spray system designed for home use comprises a chemical supply tank, a sprayer for applying a chemical in the chemical supply tank, and a coupling connecting a water source with the chemical supply tank and sprayer for mixing chemical contained in the chemical supply tank with a stream of water as the water is sprayed. The coupling comprises a first inlet configured to connect to a standard garden hose for connecting the coupling to the water source, an outlet configured to connect to a standard garden hose for connecting the coupling to the sprayer, and a second inlet configured to connect to the chemical supply tank.
