An aerosol dispensing device includes an atomizer configured to atomize a liquid contained in a cartridge, an actuator configured to actuate activity of the atomizer, a reader configured to read data attached to the cartridge while the cartridge is installed in the device and a controller. The controller is configured to receive data from the reader, verify authenticity of the cartridge based on the data received, initiate activity of the actuator based on verifying that the cartridge is authentic, and block activity of the actuator based on verifying that the cartridge is not authentic.

A spray gun includes a machine body, a gun body and a spray cup. A motor is provided in the machine body. A gas exhaust port and a gas intake port communicating with the gun body are provided on a gas outlet passage on the motor. A pressure relief valve is provided at the gas exhaust port and comprises a valve body having a valve cavity. A valve port, a pressure relief port and a mount port communicating with the valve cavity are provided on the valve body. A valve stem and a valve ball rotatable along the valve cavity are provided in the valve cavity. A valve stem spring is provided in the valve cavity to control opening and closing of the gas exhaust port. A gas outlet port is provided on the gas outlet passage. A pressure port is provided on the valve body and communicates with the valve cavity and the gas outlet port.

A fluid sprayer includes a pump and an electrostatic module configured to provide an electrostatic charge to spray fluid. The electrostatic module is electrically connected to a conductive component of the fluid sprayer, such as a fluid displacement member, fitting, cylinder, or spray tip, to charge the spray fluid via the conductive component. The fluid is electrostatically charged prior to exiting the fluid sprayer.

An air treatment system is provided which includes an appliance and a replaceable cartridge installable therein. The replaceable cartridge contains a liquid compound to be aerosolized and has a cartridge outlet through which the aerosolized compound is discharged during operation. A pump is provided to supply air to the replaceable cartridge to generate the aerosolized compound from the liquid compound contained in the replaceable cartridge, and a controller is provided for controlling the pump to supply the air to the replaceable cartridge to generate and discharge the aerosolized compound from the appliance. The appliance may further include a lift mechanism to assist in receiving the cartridge and moving the cartridge from a loading position to an operational position. The appliance may also communicate with a smartphone or other external device to provide additional functionality.

A flexible dispensing apparatus for coupling to pressurized fluid containers is described. It includes a flexible tube and a handle assembly. The handle assembly houses a second end of the tube. The handle assembly has a first side connected to a second side, a slide trigger, a roller coupled to the bottom of the slide trigger with a dowel pin, a spray nozzle assembly, a magnet reservoir, and a magnet. The first side has an inclined ramp that runs along a length of the first side and extends into the second side above and beyond a seam that is formed by the connection of the two sides. The tube is within a channel in the handle assembly formed between the inclined ramp and the roller. When the roller is rolled toward the end of the ramp it pinches the flexible tube near the top of the inclined ramp.

A portable pressure washer comprising a backpack a first tank, the first tank comprising a selectively removable cap and a quick connect, a second tank, the second tank comprising a selectively removable cap and a quick connect, at least one pump and a manifold coupled to the first tank, the second tank and the pump, wherein the first tank, the second tank and the manifold are configured to fit inside of a backpack.

A device for generating a scented mist of an atomized liquid fragrance oil includes an atomizer complex, a reservoir assembly, a drainage tube, and a vacuum tube. The atomizer complex can atomize the liquid fragrance oil into a scented mist and deliver the scented mist to air outside of the atomizer complex, where the liquid fragrance oil the fragrance oil that is not atomized into the scented mist delivered to the air outside of the atomizer complex includes collected oil that is collected and drained to a reservoir assembly. A drainage tube extends from a bottom area of the atomizer complex into the liquid fragrance oil. The device can filter the liquid fragrance oil in the reservoir assembly and the collected oil from the atomizer complex that drained down the drainage tube. The vacuum tube can suction the filtered liquid fragrance oil and the collected oil into the atomizer complex for atomization.

A generator of air/oil mist includes an accumulation chamber for a mist of particles of oil in air, and equipped with a first mist outlet and a nebulizer feeding into the accumulation chamber, the nebulizer including a first nozzle supplied with pressurised air, which features at least a first channel supplied with the pressurised air, each channel being equipped with an outlet on a surface of the first nozzle partially defining a first chamber axially symmetrical with respect to an axis, the channels being positioned to generate a rotation of the air fed into the first chamber around the said axis, the surface of the first nozzle featuring a section converging towards an outlet hole, the nebulizer featuring a second nozzle supplied with oil and feeding out into the first chamber so that the oil is suctioned via the second nozzle because of the air flowing through the first chamber.

An air/oil mist generator (1A) including an accumulation chamber (2) inside which a mist of oil particles in air accumulates, the accumulation chamber (2) being provided with at least a first mist outlet (4), the generator (1A) comprising a nebulizer (3, 3A) feeding into the said accumulation chamber (2), the nebulizer (3) being optimised to operate at a first pressure level and being fed by a first line (BA) of compressed air at the said first pressure level, the generator (1A) further including a further nebulizer (3A) which also feeds into the accumulation chamber (2) optimised to operate at a second pressure level which is higher than the first pressure level, the further nebulizer being fed by a second line (AL) of compressed air at the second pressure level; the first line (BA) being optionally associated with a non-return valve (807) which prevents a backflow coming from the accumulation chamber (2).

An air/oil mist generator (1, 1A), comprising an accumulation chamber (2) inside which a mist of oil particles in air accumulates, the accumulation chamber (2) being provided with at least one first mist outlet (4), at least one nebulizer (3, 3A) feeding into the said accumulation chamber (2), wherein the accumulation chamber (2) is associated with a differential pressure regulator (12), which feeds the compressed air into the accumulation chamber when the difference between the internal pressure of the accumulation chamber (2) and the nebulizer supply pressure (3) exceeds a predefined threshold value.
