The present disclosure relates to a spraying apparatus for spraying a liquid onto a surface. The spraying apparatus includes a tank configured to store a liquid, a neck extending from the tank and defining an opening, a pump assembly including a collar removably attached to the neck, a pump configured to draw the liquid from the tank when actuated, and a housing defining a cavity therethrough to provide a carrying handle. A wand, separate from the tank, includes a body and a nozzle assembly, having a hub rotatably attached to the body and a plurality of nozzles circumferentially arranged around the hub and extending radially outwardly therefrom. An elongate hose, having a first end and a second end, interconnects the tank and the wand by attaching to the pump assembly of the tank at the first end and the body of the wand at the second end.

The present invention relates to the application of liquid active substances. The subject matter of the present invention is a system, a method and a computer program product for the application of an active substance concentrate from a replaceable cartridge in a diluted form onto a target object with the aid of a portable spray device, wherein important parameters of the spray process are exchanged between the cartridge and/or the spray device and/or an external computer system.

A pesticide volume meter for a pesticide spray system comprises a flow sensor, which measures a flow rate of a pesticide dispensed by the pesticide spray system. The pesticide volume meter also comprises a memory and a control unit. The control unit determines a volume of pesticide dispensed by the pesticide spray system based on the measured flow rate, and stores the determined volume in the memory.

A portable liquid mister assembly capable of being worn on a person's back. It includes a liquid reservoir, a pressure pump and a DC power supply and a misting wand assembly. When a person pulls the trigger of the misting wand, a very fine mist of approximately two-hundred-micron liquid droplets is emitted from the misting head. The liquid inside the reservoir is non-pressurized and becomes pressurized when it enters the pressure pump. Therefore, the liquid reservoir does not have to withstand excessive pressures during use. Spare power supply batteries may be carried in pockets attached to the reservoir. The reservoir holds approximately three gallons of liquid.

A fluid spray apparatus includes at least one inlet and first and second outlets. A first actuator may communicate a first inlet with one of the outlets. A second actuator also may communicate a second inlet with a different one of the outlets. A passage network of the fluid spray apparatus communicates the first and second actuators with the first and second outlets. A diverter structure is disposed in the passage network. The diverter structure includes a first diverter structure arrangement. In the first diverter structure arrangement, the first actuator communicates the first inlet with the first outlet and the second actuator communicates the second inlet with the second outlet. The diverter structure also includes a second diverter structure arrangement. In the second diverter structure arrangement, the first actuator communicates the first inlet with the second outlet and the second actuator communicates the second inlet with the first outlet.

The invention relates to the application of liquid active substances with the acid of a portable spray device. The subject matter of the present invention is a system comprising a portable spray device and a replaceable cartridge that contains an active substance concentrate. The invention also relates to method for applying a liquid active substance formulation. In addition, the invention discloses a replaceable cartridge that has a memory unit in which information is stored relating to an adjustable dilution ratio for the active substance concentrate contained in the cartridge. The invention also relates to a spray device comprising a control unit that can be read out a memory unit of cartridge attached to the spray device and, on the basis of the read out information, adjust a dilution ratio for the active substance concentrate contained in the cartridge.

A fluid spray apparatus includes at least one inlet and first and second outlets. A first actuator may communicate a first inlet with one of the outlets. A second actuator also may communicate a second inlet with a different one of the outlets. A passage network of the fluid spray apparatus communicates the first and second actuators with the first and second outlets. A diverter structure is disposed in the passage network. The diverter structure includes a first diverter structure arrangement. In the first diverter structure arrangement, the first actuator communicates the first inlet with the first outlet and the second actuator communicates the second inlet with the second outlet. The diverter structure also includes a second diverter structure arrangement. In the second diverter structure arrangement, the first actuator communicates the first inlet with the second outlet and the second actuator communicates the second inlet with the first outlet.

A harness for a portable lawn/garden fluid sprayer having a tank and a spray hose is provided. The harness generally includes a first strap adapted to securely wrap around the tank adjacent the top thereof and having a first end and a second end that are interconnected by a first fastener that permits adjustment of the first strap; a second strap adapted to securely wrap around the tank adjacent the bottom thereof and having a first end and a second end that are interconnected by a second fastener that permits adjustment of the second strap; third and fourth straps that each tautly extend between the first and second straps and each having first ends that extend through a third fastener and fourth fastener, respectively, that permit the length of the third and fourth straps, and hence the distance separating the first and second straps, to be selectively adjusted; and first and second handles attached to the first strap.

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).
