An electrically powered, portable fluid dispenser that includes a main housing and extendable wand that when used in conjunction with an electric motor, a self-feeding tentacle pumping spinning element, tentacle feed tube, and focusable vibrating backstops, is able to pump, atomize, and dispense, low and high viscosity fluid with controlled directionality and droplet size.

A low-pressure spraying equipment for atomizing a working fluid at a low-pressure, includes a spray tip body having a top and a lower end, a handle arranged on the top of the spray tip body, and a chamfer defined at the lower end of the spray tip body. The spray tip body further includes a retaining shoulder and a ring collar, a mounting hole having a channel axis, a pre-atomizing component, and a tip atomizing component. The pre-atomizing component further includes a feeding channel, a pre-atomization channel, and a pre-atomization regulating channel. The feeding channel, the pre-atomization channel, and the pre-atomization regulating channel are three coaxial hollow channels sequentially defined and connected along the channel axis inside the pre-atomizing component.

A low-pressure spraying equipment includes a spray tip body having a top and a lower end, a handle arranged on the top of the spray tip body, and a chamfer defined at the lower end of the spray tip body. The handle further includes a spray direction indicator on a side of the handle. The spray direction indicator is designed to point to a discharge direction of the spray tip body. The spray tip body further includes a retaining shoulder and a ring collar, a mounting hole having a channel axis, a pre-atomizing component, and a tip atomizing component. The pre-atomizing component further includes a feeding channel, a pre-atomization channel, and a pre-atomization regulating channel. The feeding channel, the pre-atomization channel, and the pre-atomization regulating channel are three coaxial hollow channels sequentially defined and connected along the channel axis inside the pre-atomizing component. The feeding channel, the pre-atomization channel, and the pre-atomization regulating channel form a dumbbell-shaped hallow structure. The pre-atomizing component and the tip atomizing component are connected to each other sequentially along the channel axis, in a fluid stream direction.

A chemical discharging fan system has a ducted fan adapted and configured to generate a flow of air from an inlet of the fan into a duct of the fan and through the outlet of the fan. A spray gun is arranged on the fan in the flow of the air generated by the fan. The spray gun has a fluid inlet adapted and configured to receive a pressurized fluid from a fluid supply source. The spray gun is configured to intermittently discharge the fluid from the fluid source into the flow of air generated by the fan. A control is in communication with the spray gun. The control is configured to generate a pulse width modulated signal to cycle the spray gun, which causes the fluid to vaporize upon being discharged from the spray gun into the flow of air generated by the fan.
