The power source 102 is coupled with the motor and pump assembly 104. The motor and pump assembly is coupled with the tip insert 112 in nozzle assembly 106. In particular embodiments, an air valve is disposed between the motor and air pump assembly 104, and fluid source 110 and the tip insert 112. The fluid source 110 and motor and pump assembly are coupled with the tip insert 112 nozzle assembly 106. In the illustrated example, the actuation mechanism (trigger) 108 is coupled with the motor and pump assembly 104 and the fluid source 110. Those skilled in the art should readily appreciate that the arrangement of the components 102, 104, 106, 108, 110, 112 for the sprayer 300 was selected merely for ease of illustration and that the components 102, 104, 106, 108, 110, 112 for the sprayer 300 may be arranged in any desirable configuration.

The power 102 source may be any suitable power source, including but not limited to a coupling for an external power source, a battery and a rechargeable battery. The power source 102 may provide any desired voltage and/or current. In an example embodiment, the power source 102 comprises a rechargeable battery pack that is capable of providing power enabling the sprayer 300 to be able to run continuously for up 30 minutes on a single charge.

In an example embodiment, the motor and pump assembly comprises a Direct Current (“DC”) motor that operates the pump. The pump is capable of delivering up to 25 (pounds per square inch (“psi”) and 0.5 standard cubic feet per hour (“scfh”).

In an example embodiment, the fluid source is a disposable fluid source containing paint. A tube (see e.g., 702 in FIG. 7) couples the fluid source to the disposable tip insert 112. In an example embodiment, the fluid source is an aerosol fluid source. In particular embodiments, the fluid source is a transparent container that can allow a user to see the color of the fluid (e.g., paint).

In an example embodiment, the actuation mechanism 108 has a first setting (e.g., “ON”) and a second setting (e.g., “OFF”). The actuation mechanism can 108 be a switch, and in particular embodiments, a trigger switch. When in the first (“ON”) position, power is provided from the power source 102 to the motor and pump assembly 104 causing the motor and pump assembly 104 to provide air to the tip insert, 112 and the fluid source 110 is operable to provide fluid (e.g., paint) to the tip insert 112. The fluid from the fluid assembly is mixed with the air at the tip insert and the mixed fluid and air are dispensed from the tip insert.

The fluid source 110 is and motor and pump assembly are coupled with the tip insert 112 nozzle assembly 106. In the illustrated example, the actuation mechanism is coupled with the motor and pump assembly 104 and the fluid source 110. Those skilled in the art should readily appreciate that the arrangement of the components 102, 104, 106, 108, 110, 112 for the sprayer 100 was selected merely for ease of illustration and that the components 102, 104, 106, 108, 110, 112 for the sprayer 100 may be arranged in any desirable configuration.

The power 102 source may be any suitable power source, including but not limited to a coupling for an external power source, a battery and a rechargeable battery. The power source 102 may provide any desired voltage and/or current. In an example embodiment, the power source 102 comprises a rechargeable battery pack that is capable of providing power enabling the sprayer 100 to be able to run continuously for up 30 minutes on a single charge.

In an example embodiment, the motor and pump assembly comprises a Direct Current (“DC”) motor that operates the pump. The pump is capable of delivering up to 25 (pounds per square inch (“psi”) and 0.5 standard cubic feet per minute (“scfm”).

In an example embodiment, the fluid source is a disposable fluid source containing paint. A tube (not shown, see e.g., FIG. 4) coupled the fluid source to the disposable tip insert 112. In an example embodiment, the fluid source is an aerosol fluid source. In particular embodiments, the fluid source is a transparent container that can allow a user to see the color of the fluid (e.g., paint).

In an example embodiment, the actuation mechanism 108 has a first setting (e.g., “ON”) and a second setting (e.g., “OFF”). The actuation mechanism can 108 be a switch, and in particular embodiments, a trigger switch. When in the first (“ON”) position, power is provided from the power source 102 to the motor and pump assembly 104 causing the motor and pump assembly 104 to provide air to the tip insert, 112 and the fluid source 110 is operable to provide fluid (e.g., paint) to the tip insert 112. The fluid from the fluid assembly is mixed with the air at the tip insert and the mixed fluid and air are dispensed from the tip insert.

In an example embodiment, the fluid does not pass through the pump assembly. Thus, the pump does not get contaminated by fluid (paint) which can allow for easily changing colors of paint during operation by changing the disposable tip insert 112 and the disposable fluid source 110.

In an example embodiment, the nozzle assembly 106 comprises a nose section (not shown, see, e.g., FIGS. 4 and 5). The disposable tip insert 112 is coupled with the nose section. The disposable tip insert 112 receives air from the motor and pump assembly 104 and paint from the fluid source 110. In particular embodiments, (see, e.g., FIG. 5), the disposable tip insert comprises an air forcing cone (not shown, see, e.g., FIG. 5). In some embodiments, the disposable tip insert 112 is threadably fastened to the nose section of the sprayer 100. In an example embodiment, at least one O-ring (not shown, see, e.g., FIG. 5) is employed to provide a seal between the tip insert 112 and the nose section.

In an example embodiment, the pump in the motor and pump assembly 104 is a Venturi pump.

The spray exits the disposable insert at the location 1718 indicated in FIG. 17.

In an example embodiment, air is pumped into the paint reservoir by the pump that causes the fluid in the paint reservoir to pass through the tube to the sprayer tip assembly. In this example embodiment, the pump is not wetted (i.e., the pump only provides air and no fluid passes through the pump). Thus, the nozzle and paint reservoir can be disposable. This can prevent the inadvertent mixing of colors, or contamination, of the paint being applied.

In an example embodiment, the paint reservoir is clear. This can allow a user to view the color of the paint in the reservoir. This can aid the user in mixing paint to discern the color of the contents while mixing.

In an example embodiment, the sprayer is hand held and weights less than 1,000. The approximately dimensions are less than 25 centimeters (“cm”) in length, less than 25 cm in height, and less than 10 cm in width. The paint reservoir is removable and in particular embodiments holds approximately 200 milliliter (“mL”) of fluid. In an example embodiment, the reservoir is disposable. In other embodiments, the reservoir is reusable. In an example embodiment, the sprayer body, handle, reservoir, and trigger mechanism are made of a durable plastic. The sprayer is capable of being dropped up to 3 meters without functional damage.

In an example embodiment, the sprayer is powered by a rechargeable battery pack and DC pump capable of delivering up to 25 (pounds per square inch (“psi”) and 0.5 standard cubic feet per hour (“scfh”). The sprayer will be able to run continuously for up 30 minutes on a single charge. The sprayer is capable of delivering up to 15 mL per minute.
