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 fluid spray single two stage nozzle includes first and second internal surfaces at first and second predetermined angles, respectively, with respect to a rotational axis of symmetry of the nozzle, wherein the first angled surface is proximate a forward opening of the nozzle, the second angled surface is aft of the first angled surface, the first angle is in a range of substantially 0.05 to thirty degrees, and the second angle ranges from substantially 0.1 to sixty degrees greater than that of the first angle.

A spray gun has a base body, a liquid-conducting device and a fastening nut, wherein the thread has a recess and the liquid-conducting device has at least one element which is radially projecting from a central liquid-conducting tube, the element fitting into the recess, so that, after unscrewing the fastening nut, the liquid-conducting device can be gripped at the projecting element in order to withdraw the liquid-conducting device from the base body. Further, a set includes a liquid-conducting device with a liquid-conducting tube, in which is arranged a sleeve with a bore.

A spray gun and a method for use thereof comprises a spray gun body, an air cap, a fluid spray nozzle having a fluid tip, a hollow needle, at least one air distribution channel for atomizing air, and at least one air distribution channel for fan air, wherein the fluid spray nozzle and the air cap are configured to direct an atomization airflow at an angle of 10 to 75 degrees, preferably 15 to 60 degrees, and more preferably of 30 to 45 degrees (relative to the coating composition jet) into composition jet, and the fluid spray nozzle and the air cap are configured to provide an atomizing air pressure to fan air pressure ratio (AA/FA) of 0.1 to 10, preferably 0.5 to 1.0, more preferably of 0.6 to 0.9, and still more preferably of 0.66 to 0.88.

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.

Disinfecting method for disinfecting a room or a surface, comprising the steps of: a) providing a fluid comprising at least one organic compound obtainable from natural substances, wherein the organic compound is provided in an non-polar or polar medium, or in a mixture of non-polar and polar media; b) mixing the fluid with a gas such that fluid particles are suspended in the gas, and an aerosol of fluid particles is formed; c) directing a flow of the aerosol formed in step b) on said surface or into said room.

A gyrating nozzle head spray gun includes grip including air inlet, valve seat, gas-delivery tube connected to valve seat and terminating in mating connection screw rod and trigger operable for letting external compressed air go into air inlet and gas-delivery tube, attachment tube connected to mating connection screw rod of the gas-delivery tube, gyrating nozzle head assembly including gas-supply tube connected to mating connection screw rod and suspended in attachment tube, bearing, cap, linking module and gyrating nozzle head mounted on one end of the gas-supply tube, and water-delivery tube having one end extended bottom of coupling hole of gas-delivery tube and connected to water tank for sucking in water and opposite end thereof inserted through gyrating nozzle head for ejecting fluid for creating mist of fine droplets upon ejection of compressed air through the gas-supply tube and oblique jet hole and central axle hole of the gyrating nozzle head.

A backpack working machine may include: a body unit comprising a liquid tank configured to store liquid; a shoulder harness unit attached to the body unit; and an ejection tube configured to eject the liquid and being on a first side relative to the body unit when the shoulder harness unit is worn on the shoulders of the user. The shoulder harness unit may include: a right shoulder harness attached to the body unit at a first attaching part; and a left shoulder harness attached to the body unit at a second attaching part. A center position between the first attaching part and the second attaching part may be on the first side relative to a gravity center position of the body unit when the liquid is stored in the liquid tank at a maximum capacity of the liquid tank.
