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.

A portable ultrafine nebulizer comprises a housing, an atomizing nozzle located at the front port of the housing, an air turbine deposited inside the housing, an air flow guide device fixed at the front port of the housing, and a water pump for pumping liquid; the air flow guide device is provided with a plurality of air flow guide blades distributed uniformly around the periphery of the atomizing nozzle, and each of the air flow guide blades is provided with a guide surface; in the atomizing nozzle is provided with a spiral channel and a fluid channel communicated with the water pump, the atomizing nozzle is provided with a spray port at the front end, and the spray port is communicated with the fluid channel through the spiral channel; the air turbine, the air flow guide blades and the spray port are distributed successively along the airflow direction.

A drive device in which a controller includes a detection determiner, a high threshold that is initially set and a low threshold are switchably set in the detection determiner as thresholds for determining whether or not to capture detection signals, the controller performs: when the detection determiner makes a capture determination before drive processing, low-switching processing to switch the threshold from the high threshold to the low threshold before the drive processing is started based on the determination results; and perform drive cancellation processing to cancel driving of a driver when the detection determiner makes a capture determination after the low-switching processing.

The invention relates to a portable spray apparatus having a carrier frame, a blower and a storage vessel for a medium to be discharged. An upper unit with the storage vessel and a lower unit with the blower are retained on the carrier frame. The two units are located in the vertical direction of the carrier frame at a spacing (z) from each other. The spacing (z) is selected so that a movement gap is formed between the upper unit and the lower unit. To limit the resilient deflection of the upper unit, there is arranged on one of the units a damping stop which limits the movement gap and damps a resilient deflection of the upper unit by abutment of the damping stop on the other one of the units.

A rotating atomizer device is provided that allows the correction of eventual separations that the random variations (of climatic and/or environmental nature) may cause in the final result of the phytosanitary treatment so that the application of the chemical products is done completely in agreement with what has been prescribed by the agronomic professional, this way achieving a greater efficiency of the phytosanitary spraying process.

A portable, battery-powered liquid sprayer is operable to eject liquids. The sprayer includes a power unit including a base having a motor housed therein. The sprayer further includes a sprayer tank including a reservoir, an outlet fluidly connected with the reservoir, and a pump fluidly connected with the reservoir and the outlet. The sprayer tank is configured for selective engagement with the power unit. When the sprayer tank engages the power unit, the motor is operable to selectively drive the pump to pump liquid from the reservoir for ejection through the outlet.

A spray jet discharging device of long range, whose function is based on the production of a powerful air stream with liquid droplets dispersed therein, the maximum velocity of the spray jet being at least 300 km/h. The air stream is produced by a centrifugal fan with a spiral housing (1). The device is mainly used for fire extinguishing. It may be mounted at fixed points or on land vehicles via a suitable support for the fan, which enables both rotation of the spray jet beam in the horizontal plane, and changing of its inclination angle in the vertical plane. It may be remotely controlled (10) or manually operated (60). There is also a version of the device for aerial fire-fighting operations (90), configured to be suspended from an aircraft, e.g. a helicopter, and a device for portable use (1 10), which can be carried by a fireman.
