Abstract:
A paint sprayer includes a frame, a motor supported by the frame, a pump operably coupled to the motor to draw paint from a paint source and pressurize the paint, and a blower supported by the frame and operable to discharge pressurized air into the pressurized paint discharged by the pump.
Abstract:
The sprayhead device includes a housing (60) having an orifice plate (62) therein with at least one orifice opening (64) therethrough. A liquid line (36) delivers liquid to the sprayhead, where it proceeds through the orifice opening, wherein the liquid flow rate through the orifice and the liquid pressure are sufficiently great relative to the size of the orifice that the liquid moves through the orifice as a continuous stream. Gas is delivered to the housing and gas flows to the interior of the sprayhead through at least two openings (68) in the housing. The gas streams (flows) intercept the liquid flow perpendicularly, approximately 180° apart. The velocity of the gas flows is sufficient to break up the liquid stream from the orifice into a spray of droplets of desired size and velocity, accelerating them out of an acceleration duct (66) exit portion of the housing.
Abstract:
A portable, battery-powered sprayer for dispensing two liquid products at the same time. A reservoir cartridge having two liquid chambers is removably installable in a reciprocating bay in the housing. First and second mating pairs of fluid connectors each have a component mounted on the cartridge and a component mounted in the housing. A cam on a pivotable lever causes the bay to move the fluid connector components into and out of engagement. The fluid connector components permit fluid flow when they are joined and prevent it when they are separated. A support beam locks the housing components of the fluid connectors in fixed relation to one another. A guide strip locks the cartridge components in the same fixed relation to one another. A docking station in the bay locates the guide strip.
Abstract:
An electrically-powered fluid sprayer employs a piezoelectric fluid pump that includes an inlet port, an outlet port, a pump chamber, and a piezoelectric element that is deformed and displaced by electrical signals supplied thereto to vary the volume of the pump chamber. Such displacement pumps fluid into the inlet port and into the pump chamber and discharges fluid from the pump chamber out the outlet port. The inlet port is in fluid communication with a fluid reservoir. Spin mechanics may be disposed downstream from the outlet port of the fluid pump and upstream from the discharge nozzle. The piezoelectric fluid sprayer may be extended to include a dual chamber piezoelectric pump that pumps different fluids (e.g., a liquid and air). The output of the dual chamber pump is mixed in a manifold and supplied downstream to the discharge nozzle. Spin mechanics may be employed in the fluid stream upstream from the discharge nozzle after the mixing.
Abstract:
A spray device is provided in which a spray stem section is secured within a passage of a spray device body. The stem section is readily removable to allow easy cleaning and also is normally made of materials which allow disposal after use of the stem section. In order to allow such use of plastics materials, in particular the stem section is associated with the passage such that seal elements isolate feed ports over a relatively broad communication band to gutter channels in the stem section. Normally a nozzle combination is secured within a jet such that this combination is also separately disposable. The nozzle combination is held within the spray stem section using a spray hood.
Abstract:
A low-cost, simple, and easy-to-use liquid soap spraying and sponge attachment for a water sprayer. The attachment includes a tubular body which forms a cavity having a first open end on the front side and a second open end on the rear side. The second open end is configured to receive the nozzle portion of the water sprayer while exposing the actuator and the handle portion of the water sprayer. The first open end is configured to allow water from the nozzle portion of the water sprayer to spray through the body in response to actuations of the actuator. A detachable circular sponge is positioned on the front side of the body, preferably using Velcro materials. A liquid soap spraying mechanism of the attachment includes a liquid soap reservoir formed within the tubular body, a liquid soap pump mechanism in the body, a liquid soap nozzle positioned on the front side of the body, and a finger trigger lever positioned on the bottom rear side of the tubular body for spraying liquid soap from the liquid soap nozzle when actuated. Thus, single-handed operation is possible wherein the end-user's hand can move the water sprayer to position the sponge for scrubbing, the user's thumb can activate the water sprayer for spraying water, and the user's index finger can activate the soap sprayer for spraying soap.
Abstract:
A cleaning liquid dispensing apparatus includes at least one container having a pump, a fluid line, a check valve, and a 3-way connector. One end of the 3-way connector is attached to a shower head pipe, an opposing end is attached to a shower head, and a remaining end is attached to one end of a fluid line. The one end of the fluid line is terminated with the check valve. The other end of the fluid line is attached to a container having a pump. If more than one container having a pump is connected to the 3-way connector; a splitter connector is connected between the 3-way connector and fluid lines. The container having a pump is filled with a cleaning liquid such as soap or shampoo. To inject the cleaning liquid into the shower stream, a push button of the pump is actuated several times until cleaning fluid in the bottle is displaced into the stream of the shower.
Abstract:
A discharge apparatus (1 or 41) for media to be atomized in ultrafine form has a discharge nozzle (3) with a sponge-like medium receiver (10), into which issue on the one hand a functionally closed source unit (50) for the medium and on the other a conveying or delivery device (11) for compressed air, so that by a control mechanism (40) initially a drop of medium spreads out in capillary manner in the receiver (10), after which by random actuation an air pressure surge flows through the receiver (10) towards the medium outlet (4). The medium is discharged from the medium receiver (10) in an already finely divided state, whirled up and once again is finely atomized in the vicinity of an impact atomizer (30) until it passes into the open with a minimum droplet size of max. 2 .mu.m.
Abstract:
An atomizer comprises an atomizing head having a spray nozzle, an assembly part mounted over the atomizing head, a fan mounted in front of the assembly part and driven by a motor inside the assembly part. The fan has a jet head, the jet head being provided at a center of the front of the fan. A delivery tube is connected between the jet head and the spray nozzle, the delivery tube is located by a cramp disposed on the frame of the fan. The fan comprises a frame disposed therearound, by which the delivery tube is guided and further comprises a hole defined beneath the frame, a first conduit and a second conduit. The first conduit is connected between the spray nozzle of the atomizing head and the hole and the second conduit is connected between the hole and the jet head of the fan.
