  • Patent number: 8857735
    Abstract: 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.

  • Patent number: 8840038
    Abstract: A method of texturing a wall or ceiling with non-acoustical joint compound by providing a collapsible bag having an opening at its top and is adapted to contain non-acoustical joint compound for forming a textured coating on the wall or ceiling and providing a spray nozzle having a low pressure input port, a joint compound suction port attached to the opening at the top of the collapsible bag, and an output port for spraying the non-acoustical joint compound. A low pressure stream of air from an air gun attached to the low pressure input port urges a small quantity of the non-acoustical joint compound to be sprayed out of the spray nozzle when the bottom of the collapsible disposable bag is raised above its top to either allow or force the joint compound to flow into the suction port and into the interior of the spray nozzle.

    Abstract: A paint sprayer includes a motor-driven multi-stage turbine for compressing air, which subsequently flows through a venturi in a paint gun to draw in paint or some other liquid from a canister. To prevent the high-pressure air from expelling lubricant from the motor's inboard bearing, a pressure responsive annular seal axially deflects and sealingly engages an axial face of the bearing. To avoid subjecting the seal and bearing to excess air pressure and temperature created by the turbine, a bypass bleed line diverts some air to atmosphere when the paint gun is closed.

    Abstract: A system and method for delivering catalytic molecular structure to a combustion chamber is disclosed. Catalyst base materials are reduced to a micronic fog by a device using the ultrasonic vibration of a piezoelectric disc. The liquid base materials evaporate instantly upon entering the engines air stream therefore releasing pure catalyst molecules into the combustion zone, thus reducing the time taken for catalytic combustion to the lowest denominator possible and allowing for the greatest effect achievable. This further reduces the amount of catalyst needed in the base solution compared to any other type of device or additive. The system also allows a user to control the delivery rate of the catalyst to the combustion chamber.

  • Patent number: 7389948
    Abstract: An airbrush spraying device particularly adapted for the application of beauty products includes a tubular main body that is attached to a pressurized air supply. A control switch is situated on a top side of the airbrush. The control switch is connected to a mechanism that controls an air valve and a position of a makeup flow control mechanism. The air valve is an on/off mechanism, but the makeup flow control mechanism includes adjusting means so that the flow rate of makeup through the airbrush can be controlled by the user. The makeup is supplied to the airbrush from one of a plurality of makeup collars that are affixed to the main body of the airbrush. In order to enable the user to accurately apply the makeup, a mirror and a standoff marker are affixed to a forward end of the airbrush.

  • Patent number: 7341208
    Abstract: A fluid can be discontinuously atomized with an atomizer of the present invention. The atomizer can include a helical spring, disk spring or gas spring, acting as a pressure spring, as an energy storage device, a cylinder, piston, two ducts and two valves. Atomization can be initiated manually by triggering a locking mechanism. The energy storage device can be disposed outside a storage container for the fluid. The energy storage device can be provided mechanical energy manually. Via the piston, the stored energy can exert pressure onto the fluid in the cylinder, which ranges from 1 MPa to 5 MPa (10 bar to 50 bar). Distribution of the droplet size in the atomized jet can be independent from the level of experience and behavior of the person actuating the atomizer, and can be adjusted in a reproducible manner. The mean droplet diameter can be smaller than about 50 micrometers. The mass flow of the fluid through the nozzle can be less than about 0.4 g/s.

  • Patent number: 7320439
    Abstract: An apparatus for the purpose of dispensing a chemical agent whose function is to detract or alternatively attract and destroy, insects, in particular, flying insects. The apparatus consists of a chemical source, a connection to a fluid source, usually water, a reservoir for chemical mixing and a pump for mixing and creating pressure. Mixing reservoir is of such size to eliminate any chance of chemical mixture separation and where the chemical mixture is agitated prior to each dispensing cycle. Fluid is disbursed under pressure through a series of atomizing devices, interconnected to the apparatus through a flexible plastic delivery conduit. The Apparatus functions are controlled through the use of an electronic interface. Preferred agent used is pyrethrum based, naturally occurring or synthesized, which possesses an antagonistic effect toward targeted pests but apparatus is designed to be adaptable to a wide range chemicals.

  • Publication number: 20070228187
    Abstract: An indexing nozzle assembly for a trigger sprayer has a manually rotatable cap mounted for rotation on a base of the nozzle assembly. Rotation of the cap relative to the base changes the nozzle assembly between an off condition where the nozzle assembly prevents liquid discharge from the trigger sprayer, and a combination of a spray condition, a stream condition, and/or a foam condition. The indexing nozzle assembly is provided with a child resistant feature in the form of a lock mechanism that prevents rotation of the nozzle cap relative to the nozzle base from the cap off condition position. The lock mechanism can be manually manipulated with one hand to disengage the lock mechanism, thereby permitting rotation of the nozzle cap from its off condition position relative to the base.

  • Patent number: 7213773
    Abstract: A nozzle spray assembly for insecticide that can be readily connected to an outlet pipe of an air blower to conveniently spray an area free of insects. The assembly is fully portable and made of two halves that define nozzle openings that may or may not be adjustable. The high pressure air flowing past the nozzle openings draws insecticide from a container through the spray assembly and nozzle openings. The fluid sucked out of the nozzle openings is sheared across the upper surfaces of the nozzle openings and turned into micro-droplets and dispersed into the air from the blower, creating a mist flow that can be directed to the area of treatment. The assembly is provided with adjustable means for connecting it to various sizes of pipe. The assembly is portable or compact, highly effective and can be used with readily available equipment.

  • Patent number: 7152813
    Abstract: A cap with a suction type spray head includes an air guiding chamber, an intake passage, an outgoing passage, a liquid sucking mouth and an air pressure balancing aperture for a container with a sprayer. The liquid in the container can be sucked out due to air pressure difference between the sucking mouth and the interior of the container. The outgoing passage at the outer end thereof is a spraying outlet, which face the liquid sucking mouth so that the liquid out of the liquid sucking mouth is atomized with the air sprayed from the spraying outlet.

  • Patent number: 7104471
    Abstract: A liquid dispensing device for dispensing a liquid into the surrounding atmosphere employs a forced airflow through a small cross-section outlet nozzle (48) to draw the liquid from an adjacent exit nozzle (50) into the airflow. The air outlet nozzle preferably has a cross-section less than that of the liquid exit nozzle. The liquid exit nozzle may partially overlie the airflow path from the air outlet nozzle. The nozzle may be formed in or carried by a unit (24) having sealed connections with the airflow source (16) and a container holding the liquid.
