A liquid spray nozzle includes a nozzle hole configured to spray a liquid toward an object, a liquid flow channel communicated with the nozzle hole, and a filter disposed in the liquid flow channel, wherein at least one of a part of the filter and a part of the liquid flow channel from the filter to the nozzle hole forms an antibacterial part.

A filter cartridge for a showerhead includes a frame having an upstream plate and a downstream plate, both having a respective plurality of openings formed therein. The frame defines at least one upstream void outside of the upstream plate, and at least one downstream void outside of the downstream plate. A filter element is coupled to the frame and has a conical configuration including upstream and downstream faces, and a sidewall extending between the upstream face and the downstream face, with the upstream face being smaller than the downstream face. The filter element is positioned relative to the frame with the upstream face in direct fluid communication with the at least one upstream void and the plurality of openings formed in the upstream plate, and the downstream face in direct fluid communication with at least one downstream void and the plurality of openings formed in the downstream plate.

An aerosol including an active material powder, a binder, and a gas is prepared. An electric field is formed between a substrate and a porous electrode. The aerosol is electrically charged. The aerosol after the electrically charging is introduced into the electric field. The aerosol passes through the porous electrode and thereby the aerosol is introduced into the electric field. At the time of the aerosol passing through the porous electrode, the aerosol comes into contact with the porous electrode and thereby the aerosol is electrically charged. In the electric field, the aerosol after the electrically charging flies toward the substrate due to electrostatic force. The aerosol adheres to a surface of the substrate and thereby an active material layer is formed.

Spray drying method and systems are disclosed that include one or more single-use components. Single-use spray drying systems can include a drying chamber with an inner surface formed of a polymeric material. The single-use components can be pre-sterilized and sterile packaged to provide improved efficiencies and greater flexibility in spray drying systems.

A handheld comminutor—spray bottle assembly includes a bottle; a comminutor; and a sprayer assembly. The bottle has an externally threaded mouth. The comminutor includes a comminutor body, with an internally threaded rim, housing a power source and an electrically connected motor. Blades connected to the motor by a shaft extend from the comminutor body. The sprayer assembly includes a spray head attached to a spray bottle cap, a siphon straw and an elongated filter housing connected with a spray head inlet, with a filter on the housing. A filter housing cap secures the filter to the housing. The spray bottle cap has an internally threaded rim and a seal ring. The comminutor rim and the spray bottle cap rim alternately connect with the mouth of the bottle. The motor rotates the shaft and the blades. Biomatter and liquid comminuted in the bottle are dispensed using the spray head.

The hand washing assembly includes a hood defining a cavity within the hood, a valve structure located at least partially within the cavity, and a lever handle. The lever handle is operatively coupled to the valve structure and configured to move the valve structure between a first position in which the valve structure prevents a flow of fluid through the valve structure and a second position in which the valve structure permits the flow of fluid through the valve structure. The lever handle includes a contact surface positioned within the cavity and configured to move toward a top wall of the hood as the valve structure moves into the second position and configured to move away from the top wall as the valve structure moves into the first position.

The present disclosure provides advantageous selectable media filter and sparger assemblies, and improved systems/methods for utilizing and/or fabricating the selectable media filter and sparger assemblies. More particularly, the present disclosure provides selectable media filter and sparger assemblies fabricated at least in part by additive manufacturing (e.g., via a 3D printing process, such as, for example, via a laser powder bed fusion (LPBF) process, via an electron-beam melting (“EBM”) process, via an inkjet or a binder-jet additive manufacturing process, etc.), the selectable media filter and sparger assemblies including a plurality of filtration and/or sparging members attached to a single housing, with each filtration/sparging member having an independent connection port.
