An aerosol unit for an aerosol dispenser, which aerosol unit comprises an axially oriented body, having a distal inlet part and a proximal outlet part; a carrier member arranged in the body, transversally to the axis between the inlet part and the outlet part; and wherein the carrier member comprises through-holes which place the inlet part in fluid communication with the outlet part, and wherein the carrier member is insert-moulded into the body such that a contact surface between the carrier and the body forms an air-tight seal.

A system can include a delivery manifold with orifice openings arranged asymmetrically. The system can include a pump configured to pressurize a (e.g., disinfecting) fluid to an ultra-high pressure (e.g., 9,000 to 50,000 PSI, 9,000 to 65,000 PSI, any pressure over 9,000 PSI, or any suitable pressure). The pressurized fluid can be expelled through a delivery manifold with asymmetrically arranged orifice openings. In some embodiments, this arrangement can release a dry disinfecting vapor into the air that can disinfect an environment, surface, or object without wetting the item to be disinfected.

A multifunctional sprinkler device concealed in a ceiling for simultaneously removing smoke and toxic gas is disclosed. The multifunctional sprinkler device concealed in a ceiling for simultaneously removing smoke and toxic gas, in the event of a fire, suctions and removes surrounding smoke and toxic gas while spraying water and at the same time, prevents suffocation by lowering a lethal dose of the toxic gas to be lower than or equal to a safe range within a short time, and provides lighting even in the event of a fire and power outage to guide rapid evacuation.

A configurable nozzle includes a nozzle body having a reception chamber configured to receive an application mixture. The nozzle body includes a nozzle orifice. At least one orifice assembly is coupled with the nozzle body, the at least one orifice assembly includes an orifice plate movably coupled with the nozzle body. The orifice plate extends along at least a portion of the nozzle orifice, and movement of the orifice plate changes one or more of the size or shape of the nozzle orifice. An orifice actuator is coupled with the orifice plate, and the orifice actuator is configured to move the orifice plate.

A conical-jet spray nozzle (1) comprises a body (2), of generally axisymmetric shape, with an inlet zone (11) for liquid and an outlet (12), and a core (3), at least partially housed in the body (2). The core (3) is arranged so as to mix the liquid passing through it with air, upstream from the outlet (12). The nozzle (1) further comprising an additional part (5), disposed downstream from the inlet face (11) and upstream from the core (3). This additional part (5) is arranged so as to gyrate a liquid jet about the axis (XX′) of the body (2).

An apparatus for creating solid or liquid nanoparticles having a nozzle to create a first particle size from a bulk liquid flow that is in fluid communication with a gas flow amplifier comprising an inlet cone connected to and in fluid communication with the inlet of a cylindrical housing; a diffuser connected to and in fluid communication with the outlet of said housing; and said housing comprising at least two rings of ports disposed of along a circumference of the cylindrical housing; and a means to inject compressed gas into the housing through said ports.

A sprayer for mixed solution and water is revealed. The sprayer can be used for cleaning objects, spraying mixed solution for agricultural purposes, and so on. The mixed solution is formed by liquid mixed with water, while the liquid can be fertilizers, pesticides, detergents, and etc. The sprayer can selectively spray out the mixed solution or water only.

A bubble water generating device, including: a flow divider, a mixer, an air intake runner, and a water outlet cover the flow divider includes at least one first water inlet hole; a first chamber is formed between the mixer and the flow divider; the mixer includes at least one second water inlet hole corresponding to the at least one first water inlet hole one by one, and at least one return hole; the flow area of each second water inlet hole is greater than that of the corresponding first water inlet hole, the return hole, the first water inlet hole and the second water inlet hole are all communicated with the first chamber; the air intake runner is communicated with the first chamber; a second chamber communicating with the second water inlet hole and the return hole is formed between the water outlet cover and the mixer.

A sprayer able to adjust a flow of mixed solution and water is revealed. The sprayer can be used for cleaning objects, spraying mixed solution for agricultural purposes, and so on. The mixed solution is formed by liquid mixed with water while the liquid can be fertilizers, pesticides, detergents, and etc. The sprayer not only can spray out the mixed solution or water selectively, but also can adjust concentration and flow of the liquid.

A gas-liquid two-phase flow atomizing nozzle includes a nozzle core, an outer sleeve, and an atomizing body. An inner cavity of the nozzle core consists of an inlet tapered section, a jet flow section, and an outlet diffusion section. The outlet diffusion section of the nozzle core is connected to an atomizing body mixing chamber. The jet flow section of the nozzle core is in communication with external atmosphere through a core air inlet hole, an air inlet buffering chamber, and a sleeve air inlet hole.
