Abstract:
An electrostatic sprayer for spraying a liquid includes a nozzle formed from a nozzle body that has an inlet for receiving a liquid and a liquid tip having an outlet for ejection of the liquid to form a liquid spray. The nozzle also includes an electrode disposed around the outlet of the liquid tip for charging the liquid. The electrode is captive in a removable cap that is that is detachably secured, e.g., via threaded connection, to the sprayer, so that the cap is removable for servicing, cleaning or replacement of nozzle components such as the liquid tip. The nozzle includes a calibratable stop mechanism for controlling a position of the electrode with respect to the outlet of the liquid tip when the cap is installed. The stop mechanism may be provided by a locking ring around a barrel of the sprayer that stops rotation of the cap.
Abstract:
The present invention relates to a pressure boosting showerhead, which consists of a housing, a ball shape connector, a rear holder, an inner holder, a separation header and an water outflow dish. Wherein, a bending second air passage and a second inlet chamber are set between the inner barrel of the rear holder and the cone tip of the inner holder. The second inlet chamber is communicated with the first inlet chamber in the housing. The second inlet chamber is communicated with the mixed chamber of the inner holder through the second air passage, to prevent water flow reversely penetrating into the air circulation path and boost pressure to maintain the water outflow of the showerhead with better impact strength to thereby achieve the purpose of saving water.

Abstract:
A method of forming droplets comprises flowing a liquid through a channel; spreading the liquid into a thin film in the channel; and impinging the thin film with a flowing gas to atomize the liquid into droplets. The droplets may then be dried to produce dried particles, such as particles comprising a pharmaceutical active agent. The droplets formed by the disclosed process have improved size and/or size distribution characteristics.
Abstract:
A sprayer which inhibits or prevents clogging from occurring in a nozzle when a liquid is ejected from the nozzle includes a nozzle having a first internal tube through which a first liquid passes, and a second internal tube through which a second liquid passes. An external tube is provided in which the first internal tube and the second internal tube are positioned so that the gas passes therebetween. In the sprayer, each distal end part of the first internal tube and the second internal tube includes a gas permeable film impermeable to each liquid, and permeable to the gas.
Abstract:
Using a simple structure, a new function is added to a liquid such as tap water by taking a gas into the liquid. The bubble-generating structure of the present invention includes (1) a water-discharging nozzle, which is provided inside a pipe, (2) a receiving member, which is situated a specified distance from the water-discharging nozzle and which includes a flow path for passing liquid emitted from the water-discharging nozzle, and (3) an air hole provided in such a way as to take air into a space between the water-discharging nozzle and the receiving member. By taking in air due to a suction force that is generated when the liquid passes along the flow path, bubbles are generated in the liquid. When such a structure for generating bubbles in the liquid is included in a showerhead, a person taking a shower using the showerhead can have a healthy and comfortable feeling while showering.
Abstract:
A control module for a nozzle arrangement, including at least one two-component nozzle for spraying a gas/liquid mixture on the zones of action between a tool and a workpiece is characterized by a gas supply line for pressurized air and a liquid supply line for pressurized liquid, both leading to the two-component nozzle, a liquid check valve in the liquid supply line, a control device to be actuated by the pressurized gas for opening or closing of the liquid check valve, a packing disposed downstream of the liquid check valve, a branch line in the form of a capillary tube extending from the packing to the or each two-component nozzle.
Abstract:
The present invention provides for a method for spray application of a coating material onto a medical device by spraying coating material from a micronozzle fabricated from a plurality of sheets that are etched with holes or openings. The openings are aligned to form fluid channels and the sheets are fused together in a planar fashion to define a micronozzle. In another embodiment, the invention provides for a method for spray application of a coating material onto a medical device using micronozzles fabricated in batches by a simplified manufacturing process. In other embodiments, the invention provides for a method for spray application of a coating material onto a medical device by spraying coating material from a micronozzle that includes a swirl or gas-assist atomizer.
