Abstract: The durability of resin components can be improved by preventing ozone from staying in gaps where there is no air flow. A cylindrical gap is provided around the outer peripheral side of the head portion between the head portion and the resin cover portion covering the outer peripheral side of the head portion. Moreover, the head portion is provided with a pilot air introduction path guiding the pilot air exhausted from the switching valves to the cylindrical gap. In addition, the arm portion is provided with a pilot air exhaust path exhausting the pilot air from the cylindrical gap to the outside.

Abstract: A sprinkler includes a compartment that surrounds its riser portion in an offset or asymmetrical configuration. More specifically, the distance of the compartments walls from those of the riser vary (i.e., increase or decrease) at different locations surrounding the riser. Put another way, the riser is closer to one side of the compartment than other sides of the compartment. This non-concentric configuration allows larger components to fit inside the compartment than would otherwise fit if the riser was symmetrically surrounded by the compartment.

Abstract: A circular sprinkler irrigation all-in-one machine capable of spraying water, fertilizer, and pesticide includes a sprinkler irrigation frame and a storage pesticide box disposed at a side of the sprinkler irrigation frame, and a top end of the sprinkler irrigation frame is fixedly connected to a lower connecting seat. The operator control the machine through a control panel to uniformly spray and irrigate crops, an area of spraying water, pesticide and fertilizer can be adjusted according to the area of crops, effectively saving water, fertilizer and pesticide resources, accurate fertilization or spraying pesticide can be achieved according to different crops, the integration of a water pipeline and a first electric power line with a main sprinkler irrigation pipe ensures that the spraying operation can be carried out regularly and continuously during rotary spraying, avoiding line entanglement, improving device versatility, overall spraying accuracy and the neatness of the device line.

Abstract: A method for the function control of an electrohydrodynamic atomizer, wherein an electrohydrodynamically atomized fluid, originating from the atomizer, is applied to a body, e.g. a person, in order to coat this body at least in certain areas, wherein the atomizer-comprises a fluid tank for storing the fluid and at least one high voltage source for making available a high voltage and at least one pump unit for transporting the fluid, wherein the fluid is delivered to a nozzle arrangement of the atomizer by means of the pump unit, and wherein the fluid is atomized electrohydrodynamically at the nozzle arrangement by means of the effect of the high voltage from the high voltage source, wherein a voltage and/or a current at the high voltage source is evaluated in order to acquire a working point of the high voltage source via a current/voltage characteristic curve.

Abstract: A power washing assembly includes a spray bar that has a fluid inlet and a plurality of spray nozzles. The fluid inlet is fluidly attachable to a fluid source to direct a fluid from the fluid source into the spray bar. Each of the spray nozzles is in fluid communication with the fluid inlet to spray the fluid. A handle is coupled to the spray bar thereby facilitating the spray bar to be steered along the support surface to clean the support surface. A leg is coupled to and angles downwardly from the handle and a roller is rotatably coupled to the leg to roll along the support surface. A hook is coupled to the handle and the hook curves upwardly from the handle thereby facilitating the hook to hold a fluid hose that is fluidly coupled to the fluid source.

Abstract: An intelligent air-assisted spraying device for orchards includes a traction mechanism, a spaying system, a collecting system, and a processing-controlling system. The traction mechanism is provided with a spray tank. The spaying system includes a main body connected to the spray tank and multiple spraying tubes, first ends of the spraying tube are communicated with the main body, and second ends of the spraying tubes are capable of rotating. The collecting system is configured to collect a contour and a volume of the canopy, and branch and leaf density of a fruit tree. The processing-controlling system is configured to obtain multiple spraying areas, calculate an air outlet angle of each spraying tube, and control a rotation of the second end of each spraying tube according to the air outlet angle. The device can adjust the spraying direction of each spraying tube, and the quality of pesticide application can be improved.

Abstract: Embodiments relate to a screen-type fire suppression system for an electric vehicle, and more particularly, to a screen-type fire suppression system for an electric vehicle which, in the event of a fire in a parked electric vehicle, unfolds a screen on the sides of the electric vehicle to prevent the spread of the fire and simultaneously increase the concentration of water sprayed onto the electric vehicle, thereby maximizing fire suppression efficiency.

Abstract: A mounting configuration for an electrostatic spray gun (100) includes a probe having a first non-conductive body encasing a first conductive element and a probe mount extending from the electrostatic spray gun with a second non-conductive body encasing a second conductive element. The mounting configuration includes a first elastomeric ring (140) disposed about the second non-conductive body and configured to interface with the first non-conductive body. The first elastomeric ring (140) is configured to exert a force on the first non-conductive body to bias the first non-conductive body away from the electrostatic spray gun (100) such that the probe is secured in a home position. A pin (128) extending from one of the first non-conductive body and the second non-conductive body is seated in a notch (138) formed in the other one of the first non-conductive body and the second non-conductive body.
