摘要:
A sprayer which inhibits or prevents clogging from occurring in a nozzle when a liquid is ejected from the nozzle at least one liquid flow path through which a liquid passes, a gas flow path connectable to a source of gas and along which a gas passes for ejecting the liquid, a first liquid supply connected to the at least one liquid flow path, and a gas permeable film including a plurality of through holes disposed along at least a portion of a wall defining the at least one liquid flow path, the gas permeable film being impermeable to the liquid and permeable to the gas such that the gas introduced into the gas flow path flows through the gas permeable film and into the at least one liquid flow path, thereby atomizing the liquid.

Provided is a gas-liquid mixing nozzle (10) including an internal air discharge path (A), an external air discharge path (D), at least one liquid introduction path (B, C) which is disposed between the internal air discharge path (A) and the external air discharge path (D) and introduces a liquid having water and/or fuel as a main component into a nozzle discharge opening (18), and an impact member (22) with which a mixture of the air and the liquid mixed with each other in the outlets of the internal air discharge path (A) and the liquid introduction path (B, C) collides, the outlet of the internal air discharge path (A) and the outlet of the liquid introduction path (B, C) being disposed on the inside of a nozzle in relation to the nozzle discharge opening (18), and the impact member (22) being disposed between, the outlets of the internal air discharge path (A) and the liquid introduction path (B, C) and the nozzle discharge opening (18). With the above-described configuration, the gas and the liquid may be highly efficiently mixed with each other, and the generation of water droplets of a liquid may be suppressed, thereby producing finer particles.

A drug delivery device mainly has a housing, which can be easily held and operated. The housing has one end formed with an adjustment seat capable of adjusting a range distance, and the other end connected to a gas pressure control source for providing mainstream and substream gas pressures. Disposed in the housing are a drug delivery pressuring tube, an embedded drug-can connecting seat or an external drug-can connecting seat, a replaceable drug-can container and a gas communication tube. According to this design, the minor liquid drug can be controlled, the drug-can can be replaced and the continuous quantitative injection of drug can be made. Also, all damaged or dirty members of the invention may be disassembled, cleaned or replaced.

A foam soap generator is provided for implementation with various types of foam soap delivery systems. The foam soap generator includes converging air and liquid soap passages at a mixing chamber, where a prefoam is generated for ultimate extrusion through a porous passage member. In one embodiment of the invention, the soap and air are delivered through coaxial tubes, with the soap being introduced axially into the mixing chamber and the air being introduced radially angularly. In another embodiment, the liquid soap is drawn into an entrainment zone by high velocity air passing through the air passageway and into the mixing chamber.

The present invention provides a perfume spray head with leakproof feature comprising a spraying unit and an annular pad, wherein spraying unit has a holding groove with an aerator, a nozzle and a 1 flow passage, a protrudent docking stem with a locking dented ring as well as a curved anchoring trough and an air inlet, and annular pad has an anchoring hole with an anchoring pin, a docking pit, a perforated positioning hole with a positioning and locking pin, an air intake passage and a flow path connected with a liquid feeding channel, as well as a coupling bushing; Thereby, the spray head is switched into “ON status” or “OFF status” when the spraying unit is turned to the position where the flow passage in or out of alignment with the flow path so that effects in component simplification, assembly easiness and cost reduction are achieved.
摘要:
Apparatus and method for depositing aerosolized material, wherein an aerosol flow is surrounded and focused by more than one consecutive sheath gas flows. The combined sheath and aerosol flows may consecutively flow through more than one capillary, thereby narrowing the flow further. Linewidths of less than one micron may be achieved.
摘要:
A sprayer is capable of inhibiting or preventing clogging occurring in a nozzle upon ejection of a liquid through the nozzle. A sprayer includes liquid supply for separately supplying a first liquid and a second liquid different in liquid composition, and a nozzle. The nozzle includes a first flow path and a second flow path along which passes the first liquid and the second liquid supplied from the liquid supply. In addition, the nozzle includes a third flow path along which passes a gas. A merge part is provided at which the first flow path and the second flow path merge at their respective halfway parts. A vent is provided at the merge part for allowing the gas which has passed through the third flow path to flow into the merge part.
