Abstract
An air brush type sprayer includes a can with a base extending from the can and a liquid outlet member is threadedly connected to a top of the base. A tube connected between an interior of the can and the liquid outlet member. A nozzle assembly is connected to a compressor and a nozzle and a connection part both extend from the nozzle assembly. The connection part is snapped to the base so that the gap is easily adjusted by rotating the liquid outlet member.
Description




FIELD OF THE INVENTION




The present invention relates to an air brush type sprayer that has a nozzle assembly snapped to a can. A liquid outlet member is threadedly connected to a top of the can.




BACKGROUND OF THE INVENTION




A conventional air brush type sprayer for spraying colored paint, stains, lacquers and the like is shown in FIG.


5


and generally includes a can


30


for receiving liquid material therein and a cap


31


threadedly connected to a top of the can


30


. The cap


31


has a threaded protrusion and a passage


311


is defined therethrough for a tube


32


extending through the passage


311


to allow a tip portion to extend from the threaded protrusion. A nozzle assembly


33


having a connection part


331


connected to the threaded protrusion and includes a nozzle


332


which is located beside the tip of the tube


32


. A valve


333


is received in the nozzle


332


and can be operated by a lever


334


which is integrally connected to the nozzle assembly


33


. The nozzle assembly


33


is connected to a compressor so as to blow pressurized air flow from the nozzle


332


to suck the liquid material in the can


30


. When adjusting the gap between the nozzle


332


and the tip, the can


30


and the nozzle assembly


33


are both rotated in opposite direction to let the connection part


331


be moved upward relative to the threaded protrusion as shown in FIG.


6


. The other way is to rotate the can


30


as shown in FIG.


7


. However, both of the two ways could disengage the can


30


and the nozzle assembly


33


. Because both of the two items are heavy so that the adjusting is inconvenient for the users. Besides, the lever


334


is integral with the nozzle assembly


33


so that once the lever


334


is broken, the whole nozzle assembly


33


has to be discarded.




SUMMARY OF THE INVENTION




In accordance with one aspect of the present invention, there is provided an air brush type sprayer and comprises a can with a cap mounted thereto and a base extends from the cap. A liquid outlet member is threadedly connected to a top of the base. A nozzle assembly has a valve received therein which is operated by a lever connected to the nozzle assembly. A nozzle and a connection part extend from the nozzle assembly. The connection part is connected to the base.




The primary object of the present invention is to provide an air brush type sprayer wherein the nozzle assembly is snapped on the can and the liquid outlet member is threadedly connected to a top of the can.




These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 1

to


4


, the air brush type sprayer of the present invention comprises a can


20


with a cap


21


mounted to a top of the can


20


and a base


24


extends from the cap


21


. A threaded tube


244


extends from the base


24


and a tube


23


communicating with an interior of the can


20


is engaged with the threaded tube


244


. The liquid outlet member


22


is threadedly connected to the threaded tube


244


. A guide member


243


extends from the base


24


and two holes


241


are respectively defined in the base


24


and separated by the guide member


243


. Two apertures


242


are defined in two sides of the base


24


and communicate with the two holes


241


.




A nozzle assembly


10


has a valve


100


received therein and a rod


101


of the valve


100


extends from the nozzle assembly


10


. A lever


11


is pivotally connected to the nozzle assembly


10


by a pin


110


and located above the rod


101


. A fitting


12


is connected to a lower end of the valve


100


so as to be connected to a compressor (not shown). A nozzle


13


and a connection part


14


both extend from the nozzle assembly


10


. The connection part


14


has two pawls


141


extending therefrom and a groove


142


is defined in the connection part


14


. The two pawls


141


are engaged with the two holes


241


in the base


24


and the guide member


243


is received in the groove


142


. The engagement of the guide member


243


and the groove


142


prevents the nozzle assembly


10


from rotating relative to the can


20


. The two pawls


141


are easily snapped to the base


24


when assembling the two items.




The gap between a tip of the liquid outlet member


22


and the nozzle


13


is simply to rotate the liquid outlet member


22


. This is convenient for the user because the liquid outlet member


22


is light in weight.




While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope and spirit of the present invention.
