Fluid delivery systems for use with power tools are provided. A fluid delivery system can include a reservoir configured to contain fluid; a manifold including a plurality of nozzles configured to be disposed at an airflow outlet of the power tool, the manifold being in fluid communication with the reservoir; a pump configured to supply fluid from the reservoir to the manifold to dispense the fluid through at least some of the plurality of nozzles; and an attachment element configured to selectively couple the manifold with the airflow outlet of the power tool.

A backpack sprayer includes a housing, a spray nozzle assembly, a fan assembly and a switch assembly. The housing is configured to contain a liquid. The spray nozzle assembly is communicated with the housing, and is configured to spray the liquid out from the housing. The fan assembly is connected to the spray nozzle assembly, and is configured to provide the spray nozzle assembly with power to spray the liquid out from the housing. The switch assembly is connected to the spray nozzle assembly and electrically connected to the fan assembly, and is configured to control opening and closing of the spray nozzle assembly and start and shutdown of the fan assembly simultaneously.

Disclosed herein is a tactical turbine aerosol generator. An embodiment of tactical turbine aerosol generator can comprise an aerosol dispersal system. The aerosol dispersal system can include an aerosol generator. The aerosol generator can comprise a solution tank assembly. The solution tank assembly can be configured to transport an aerosol solution for vaporization. The aerosol generator can further include a motor device. The motor device can be configured to vaporize the aerosol solution and expel the aerosol solution from the aerosol generator. Aerosol generator can also comprise an engine control unit in electrical communication with the motor device. The aerosol generator can include a transmitter assembly in electrical communication with the solution assembly and engine control unit. The aerosol generator can also be configured actuate operation of the aerosol generator. The aerosol dispersal system can also include an auxiliary container assembly configured to be coupled to the aerosol generator.

An adapter system for transforming an electric backpack into a sprayer for pesticides and disinfectants is disclosed, the adapter system comprising a reservoir in fluid communication with a sprayer, the reservoir to retain a liquid. One or more supply lines deliver the liquid to the sprayer having a blower with a handle portion including a first side to receive a conduit in fluid communication with a nozzle adapter and a nozzle to emit a mist therefrom. A power supply is in electrical communication with the blower to supply power thereto to provide a portable sprayer system.

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 fluid stream and passes the fluid through an electrode of a nozzle assembly to charge droplets of the atomized fluid.

Disclosed herein are methods, compositions, and kits for high efficiency, site-specific genomic editing of cells for treating or preventing genetic blood disorders.

A mist blower may include: a liquid nozzle configured to inject liquid stored in a liquid tank into an ejection tube. The liquid nozzle may include: an end surface disposed on a distal end of the liquid nozzle, an ejection opening being defined in the end surface; a side surface constituting at least a part of an outer shape of the liquid nozzle; and a corner part connecting the end surface and the side surface and constituting a corner of the liquid nozzle. At the corner part, a virtual end surface defined by extending the end surface and a virtual side surface defined by extending the side surface may intersect at a first point. Each of a distance from the first point to the end surface and a distance from the first point to the side surface may be equal to or less than 0.3 mm.

A backpack working machine may be configured to eject liquid. The backpack working machine may include: a body unit; and a shoulder harness unit attached to the body unit and configured to be worn on shoulders of a user. The body unit may include: a battery unit comprising a battery attaching part to which a battery is attached; a fan unit comprising a fan configured to operate on electrical power of the battery; and a liquid tank configured to store the liquid. When the backpack working machine is placed on a placement surface, a direction perpendicular to the placement surface may be defined as an up-down direction. When the backpack working machine placed on the placement surface is viewed from above, 50% or more of the battery unit, 50% or more of the fan unit, and 50% or more of the liquid tank may overlap each other.
