to achieve these goals, the technical solution used in the present invention is: a kind of ultrasonic hand-held atomizing lance, the base inside of this spray gun has an atomizing groove, the atomizing trench bottom is installed ultrasonic concussion sheet, liquid level sensor, be provided with part under the fluid switch in the atomizing groove, an air outlet is installed at edge at the atomizing groove, air outlet grate is arranged on air outlet, the air outlet bottom is provided with aerophor, ultrasonic concussion sheet bottom is provided with ultrasonic tr-ansducer, the spray gun fluid reservoir is installed on base top, liquid outlet is arranged at spray gun fluid reservoir bottom, liquid outlet is provided with part on the fluid switch, spray gun fluid reservoir and its top cover are flexibly connected, the spray gun fluid reservoir is the irregular geometry cavity, the outward flange suit spray gun external cavity of base, form cavity between the outer wall of the inwall of spray gun external cavity and spray gun fluid reservoir, liquid after air outlet will atomize is carried so far in cavity, the spray gun external cavity is connected with spray gun spray nozzle.
Described spray gun spray nozzle front portion is provided with the shower nozzle air inlet, and the rear portion is provided with the shower nozzle fog inlet.
On described fluid switch, part and fluid switch bottom are grouped into the fluid switching device.
Compared with prior art, base of the present invention inside is provided with an atomizing groove, the ultrasonic atomizatio process is completed in groove, ultrasonic concussion sheet is installed in the cell body bottom, liquid level sensor, part under the fluid switch, an air outlet is installed at the edge of cell body, air outlet grate is arranged, corresponding aerophor and the ultrasonic tr-ansducer installed of air outlet and ultrasonic concussion sheet bottom on air outlet.The top cover of spray gun fluid reservoir can be turned on, and is used for adding liquid.Entered by the shower nozzle air inlet when compressed air and when being sprayed by shower nozzle, can be simultaneously by the liquid after shower nozzle fog inlet suction atomizing, final liquid through ultrasonic atomizatio is sprayed by spray gun spray nozzle, can be widely used in various need to the occasion of the ejection after the atomization of liquid, especially can being applied to manually pcb board be welded front scaling powder spraying.
Description of drawings
Fig. 1 is spray gun decomposing schematic representation of the present invention.
Fig. 2 is flow direction after the atomization of liquid of the present invention and the flow direction schematic diagram of extraneous gas.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
The invention provides a kind of ultrasonic hand-held atomizing lance, mainly convert electrical energy into the mechanical oscillation of ultrasonic concussion sheet by ultrasonic tr-ansducer, make the atomization of liquid of spray gun fluid reservoir, by air outlet, the mist that produces is delivered to space between spray gun external cavity and spray gun fluid reservoir again, at last by traditional pneumatic sprayhead with the external compression air with atomize after liquid together sprayed by shower nozzle.
referring to Fig. 1, a kind of ultrasonic hand-held atomizing lance, base 6 inside of this spray gun have an atomizing groove, the atomizing trench bottom is installed ultrasonic concussion sheet 9, liquid level sensor 8, be provided with part 10 under the fluid switch in the atomizing groove, an air outlet 5 is installed at edge at the atomizing groove, air outlet grate is arranged on air outlet, air outlet 5 bottoms are provided with aerophor, ultrasonic concussion sheet 9 bottoms are provided with ultrasonic tr-ansducer, spray gun fluid reservoir 4 is installed on base top, liquid outlet is arranged at spray gun fluid reservoir bottom, liquid outlet is provided with part 7 on the fluid switch, spray gun fluid reservoir and its top cover are flexibly connected, the spray gun fluid reservoir is the irregular geometry cavity, the outward flange suit spray gun external cavity 3 of base 6, form cavity between the outer wall of the inwall of spray gun external cavity 3 and spray gun fluid reservoir 4, liquid after air outlet will atomize is carried so far in cavity, spray gun external cavity 3 is connected with spray gun spray nozzle 1.
