A particulate sprayer includes a gas reservoir to hold a gas, a liquid reservoir to hold a product, and a low pressure section including an exit opening connected to the liquid reservoir. The product includes a liquid and solid particles. The low pressure section transports gas released from the gas reservoir over the exit opening. The product is drawn, pushed, or drawn and pushed from the exit opening into the transported gas to create a spray of the product to be sprayed from the particulate sprayer.

A marker airbrush device for transferring marking solution from a marking device onto a writing surface using air is provided. The airbrush device includes a housing with an air outlet, a trigger for controlling an amount of air travelling through the air outlet, and a marker positioner coupled to the housing. The marker positioner positions a marking device relative to the air outlet such that air traveling through the air outlet contacts at least one surface of the marking device to transfer marking solution onto a writing surface. In embodiments, rotation of a portion of the marker positioner advances and/or retracts the marking device with respect to the flow of air through the air outlet, thereby altering the angle and/or amount of air that contacts the marking device during spraying. In another embodiment, the marker positioner includes a locking lever for engaging against the marker device nib and/or housing.

The backpack paint sprayer comprises a backpack, a spray gun, and a hose assembly. The backpack paint sprayer may be a portable spray-painting system. The backpack may carry a supply of paint which may be pumped from the backpack to the spray gun via the hose assembly. A turbine located within the spray gun may create an air stream that may atomize the paint and may disperse the paint over a surface being painted. The backpack may be adapted to be worn by a user and may enable the user to move about without being constrained by a paint supply hose coupled between the spray gun and a compressor.

The appliance (10, FIG. 1) includes a body portion (27) and a nozzle portion (30) through which a spray of liquid droplets exits from a distal end thereof for cleaning of dental regions. The nozzle includes an orifice (36) at a proximal end thereof adjacent the body portion, as well as a pump (38) for moving liquid into an area of the nozzle just forward of the orifice. A mechanical system (12, 13, 14) is provided for moving a plunger or piston element (16) first away from the orifice under tension, such as a compression spring (24), and then controllably releasing the plunger or piston toward the orifice, the plunger/piston moving with sufficient force that atmospheric air which has been drawn into the appliance between the plunger or piston is forced through the orifice at a sufficiently high rate of speed to produce a spray of fluid droplets for dental cleaning when the moving air comes into contact with the liquid in the nozzle.

A marker airbrush device for transferring marking solution from a marking device onto a writing surface using air is provided. The airbrush device includes a housing with an air outlet, a dual-action trigger for controlling an amount of air travelling through the air outlet, and a marker positioner coupled to the housing. The dual-action trigger may be either pushed down or pulled back to control air flow through the air outlet. The marker positioner positions a marking device relative to the air outlet such that air traveling through the air outlet contacts at least one surface of the marking device to transfer marking solution onto a writing surface. The marker positioner may include a rotatable collar that couples the marking device within the marker position and creates a seal around the marking device to prevent pressurized air from escaping around the marking device.

A handheld sprayer includes a housing, a turbine, a spray tip, and a hopper. An air flow passage extends through the housing. The turbine is configured to generate an airflow within the air flow passage. The spray tip is positioned to receive airflow from the air flow passage. The hopper is connected to the housing and configured to discharge a fluid into the air flow passage. In one embodiment a valve is positioned within the air flow passage and configured to control the airflow from the turbine to the spray tip. In another embodiment, a voltage limiting circuit is configured to control voltage to an electric motor of the turbine to control speed of the turbine. In another embodiment, an air inlet control device is configured to control the air intake of the turbine.

A device for dispensing a mist of an ophthalmic fluid includes a discharge opening for said mist, a mixing chamber communicating with said discharge opening, an air chamber holding a volume of air, a first drive operable to expel air from said air chamber, a fluid chamber for holding a volume of the fluid to be dispensed and communicating with said mixing chamber, a second drive for delivering a predetermined dose of said fluid to said fluid chamber, said air chamber communicating with said fluid chamber and with said mixing chamber, said device establishing one flow of expelled air flowing into said fluid chamber, so as to force liquid from said fluid chamber into said mixing chamber, and another flow of said expelled air flowing past said fluid chamber into said mixing chamber.

There is provided a flavor dispenser apparatus that allows flavored aerosols to be dispensed into a glass, plate, or other dishware during a meal or the like. The flavor dispenser apparatus includes a storage part storing an aerosol-generating liquid, a heating unit having a heater and generating an aerosol by atomizing the aerosol-generating liquid, a liquid delivery unit delivering the aerosol-generating liquid to the heating unit, an aerosol passage having at a distal end thereof an aerosol outlet port, a flavor source holding part provided at an intermediate point in the aerosol passage and holding a flavor source so as to allow passage of the aerosol, and an aerosol-pumping unit transporting the aerosol toward the flavor source holding part and causing the aerosol to pass through the flavor source as well as causing the aerosol flavored by the flavor source to be discharged from the aerosol outlet port.

A spray gun includes a spray gun body and an atomization hood arranged at an outlet of the spray gun body, and a pipeline is arranged in the spray gun body; the spray gun further includes a cleaning joint and a straw component that are installed on the spray gun body, the atomization hood and the cleaning joint are detachably installed at the outlet of the spray gun body, and the atomization hood and the cleaning joint are used alternately; the cleaning joint is connected with one end of the pipeline, and the straw component is correspondingly connected with the other end of the pipeline.

The present disclosure provides aerosol delivery devices having a variety of configurations and arrangements. Some aspects of the disclosure provide aerosol delivery devices having a first pump configured to deliver a flow of air; a second pump configured to deliver a flow of liquid; and a nozzle configured to receive the flow of air and the flow of liquid and output the liquid in an atomized form.
