An air passage and two lines of cleaning liquid paths are provided in a nozzle, and the air passage is bifurcated into two lines of distal end portions. A secondary tank is provided upstream of the cleaning liquid paths. A distal end portion of a cleaning liquid path and the distal end portion of the air passage are merged. When a compressed air is supplied to the air passage, the resulting air flow makes the inside of the secondary tank to be negative pressure. Thus, the cleaning liquid can be made into the form of a mist, and is suctioned, and the cleaning liquid in the form of a mist and the compressed air are mixed, whereby it is possible to clean a lens surface and to reduce the amount of cleaning liquid used.

A smart fluid application system and method for the delivery of a fluid to a discreet location is disclosed in the present application. The system and method utilize a rigidly affixed port block with multiple discharge ports, where each port has at least two apertures, all of which are positioned and designed to dispense a fluid only to a pre-determined location. At least one sensor detects an event and directs the release of fluid through a specific port and ceases the release when the event is ended. Such a system and method may be used anywhere a precise application of fluid is required.

An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.

A showerhead assembly including a plurality of scanner nozzles. Each scanner nozzle includes an oscillation chamber fluidly coupled to an inlet aperture and an outlet aperture, and configured to discharge a random sweeping jet from the outlet aperture over a coverage area.

An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure air stream and passes the fluid through an electrode inside a nozzle assembly to charge, such as negatively charge, droplets of the atomized fluid. The system uses a unique nozzle design that is configured to optimally atomize the fluid into various sized droplets.

A backpack working machine may include: a body unit comprising a liquid tank configured to store liquid; a shoulder harness unit attached to the body unit; and an ejection tube configured to eject the liquid and being on a first side relative to the body unit when the shoulder harness unit is worn on the shoulders of the user. The shoulder harness unit may include: a right shoulder harness attached to the body unit at a first attaching part; and a left shoulder harness attached to the body unit at a second attaching part. A center position between the first attaching part and the second attaching part may be on the first side relative to a gravity center position of the body unit when the liquid is stored in the liquid tank at a maximum capacity of the liquid tank.

A shower head (10C) has at least one mixing chamber (24) having an air inlet (18) for connection to a supply of pressurized air and a water inlet (22) for connection to a supply of pressurized water so that, in use, the air breaks the water up into droplets in the mixing chamber. The mixing chamber further has at least one outlet (32) so that, in use, the water droplets and air exit the shower head to form a shower of water droplets having a mean trajectory. The or each outlet is arranged so that, in use, at least a substantial proportion of the water droplets exit the shower head so that their individual trajectories on leaving the shower head are offset from the mean trajectory of the shower head and converge towards the mean trajectory of the shower head. This can result in a more uniform distribution of water droplets in the shower pattern. A single annular outlet may be provided, or a plurality of separate outlets. In order to assist in breaking up the water into small droplets, a vortex may be induced in the air and/or the water in the mixing chamber, and/or a deflector may be disposed adjacent the water inlet into the mixing chamber.

A spray head assembly comprising a body configured to receive a supply of fluid and a face in fluid communication with the body, the face having a plurality of nozzles arranged in a non-linear pattern for directing the fluid from the spray head, wherein the plurality of nozzles are configured to direct the fluid flow to form a wedge-shaped spray pattern between the face and a focal region at a focal length from the spray head, and wherein the spray pattern forms a linear spray arrangement in the focal region.

A spray head for directing water into a spray pattern that includes a casing configured to receive a supply of water and a plurality of nozzles disposed on the casing with each nozzle being configured to emit water in a stream away from the casing. The plurality of streams of water from the plurality of nozzles are configured to form a hyperboloidal shaped spray pattern.
