A head of a blow gun includes an inlet and an outlet openings formed by a main channel. The main channel defines a first section with a first open end adjacent to the inlet opening and a second open end and a second section with a first open end adjacent to the second open end of the first section and a second open end adjacent to the outlet opening. The second section has a cross section including two opposite short sides and two opposite long sides. The outlet opening is delimited by the short sides and long sides and has a long width between the short sides and a short width between the long sides respectively. At least one side channel has a first open end allowing the outside air to flow therein and a second open end fluidly connected to the second section.

A fluid discharge mechanism includes a valve chamber having a linking portion linked to a pressurization space for a fluid, a first communication portion formed on a side opposite to the linking portion, and a second communication portion formed at a location between the linking portion and the first communication portion; a main flow channel communicating the second communication portion with a discharge opening; a sub-flow channel communicating the first communication portion with the main flow channel; and a valve member located inside the valve chamber and formed so as to move forward to the first-communication-portion side when the pressurization-space side reaches a predetermined pressure, to open the second communication portion, thereby performing the discharge, and so as to move backward to the communication-portion side after completion of the discharge.

Air injectors are provided for conveying fluid and/or gas (e.g., air) into the fluid of a bathing apparatus. The air injectors can include a component for attachment to an outside surface of the bathing apparatus that can be hidden from the view of a user and another component for attachment to a source of the fluid and/or gas (e.g., air). The two components can be connected together for use or disconnected for servicing and cleaning the injectors, as well as servicing a check valve or the injectors.

A cleaning head is disclosed for use in a traversing shower system. The cleaning head includes a plurality of directional fluid nozzles for discharging a fluid, each of which is provided along a different direction toward a work surface such that no two directions cross one another between the cleaning head and a working surface.

A compact hot air gun comprising a body, an air blowing pump, an air outlet tube, and a heating coil. The air blowing pump is disposed in the body. The air outlet tube has an end connected to the air blowing pump and another end extending beyond the body. The heating coil is disposed in the another end of the air outlet tube opposite to the air blowing pump. The compact hot air gun can generate an ignition effect by using hot air through the above structure.

A method of dispensing a fluid in a semiconductor manufacturing process includes providing a substrate, positioning a nozzle above the substrate, and determining a cross-sectional shape of the nozzle. The method also includes configuring the nozzle to have the determined cross-sectional shape and applying the fluid to the substrate through the nozzle with the determined cross-sectional shape.

A nozzle device 1 includes a main body 10 that is formed of a main-body first member 11 and a main-body second member 22 and that has an internal accommodation space 21 in which members are accommodated, a movable nozzle portion 30 that is accommodated in the accommodation space 21, and a coil spring 2 that is disposed between the movable nozzle portion 30 and the main body 10. When air is supplied to a main-body flow-path portion 23 from below, the flow path of the air is changed by the Coanda effect in an air guiding portion 27 such that the air flows along the air guiding portion 27, and the air flows into a gap between an air receiving portion 36 and the air guiding portion 27 and is guided to the air receiving portion 36. The air is pressurized in the air receiving portion 36 and pushes up the movable nozzle portion 30.

A nozzle for a filter cleaning system has a stub portion having an inlet opening and an outlet opening, and a splitter portion positioned downstream of the stub portion. The splitter portion has deflector surfaces arranged to direct the airflow exiting the stub portion outlet in 3 or more different/separate airstreams each of which airstreams are directed inclined axially outwardly from the axial direction of the airflow exiting the stub portion outlet opening. The various parameters of the splitter nozzle portion can be tailored to provide required jet shape and entrainment characteristics. A beneficial feature of the nozzle designs is that jet entrainment and recombination of flows can be specified for different shaped filters.

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

The invention discloses a nozzle structure for a quick freezer, including a plurality of conical diversion channels, a plurality of jet channel, a plurality of hemispherical nozzles and a steel belt. The nozzle structure is a funnel-shaped structure formed by the conical diversion channel, the jet channel and the hemispherical nozzle. The nozzle structure of the present invention can effectively improve flow area at the cross-flow direction, and a fluid buffer area is formed between two adjacent nozzles, which can reduce the cross-flow effect, and improve the heat exchange rate of the surface of the steel belt, thereby reducing the freezing time of food, improving the freezing efficiency of the quick freezer, and reducing the energy consumption.
