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 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.
Abstract:
An atomizer includes two reservoirs for receiving two different liquids to be atomized and two paths extending from the two reservoirs are merged into a micro-mixing passage which has a nozzle at a distal end thereof. A high pressure reservoir for receiving a gas includes an outlet passage which is connected between the high pressure reservoir and the nozzle. The two liquids are mixed in the micro-mixing passage and hit by the high speed gas coming from the high pressure reservoir so that the two liquids are atomized.
Abstract:
Methods and apparatus particularly useful for atomizing a heavy highly viscous liquid into fine droplets (such as petroleum distillate resid to droplets on the order of 100 thousandths of a millimeter), with the aid of at least one auxiliary gas. This employs in a nozzle head an array of a plurality of primary channels and at least two secondary channels associated with each said primary channel. The primary channels each have an inlet end connected to a high pressure source of liquid, and have an outlet end defining an atomization orifice. The secondary channels each have an inlet end being connected to at least one source of auxiliary gas and an outlet end. The outlets of the secondary channels each intersect with a commonly associated primary channel at the same or different locations upstream of the respective atomization orifice at angles of less than 90.degree., typically 45.degree. or less. Liquid is passed through a plurality of primary channels thereby forming a liquid core stream. At least one auxiliary gas is injected under pressure into each respective primary channel from at least two secondary channels associated with each primary channel, thereby atomizing the liquid.
