ABSTRACT:

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.
