1. A self contained, cordless, handheld spray gun, comprising:
a gun body;
a power source internal to the gun body;
a source of compressed gas internal to the gun body;
a gas nozzle assembly with at least one gas nozzle orifice, said gas nozzle assembly able to regulate the gas flow at the gas nozzle orifice;
a tube assembly coupling the source of compressed gas to the gas nozzle assembly;
a container for holding fluids appurtenant to the gun body;
a fluid chamber coupled to the container for holding fluids;
at least one fluid nozzle orifice at an end of the fluid chamber;
a trigger having a first and second stage, the first stage turns on the source of compressed gas and the second stage causes fluid to be released from the fluid chamber through the fluid nozzle orifice at the end of the fluid chamber when actuated; and
a regulator for controlling the amount of compressed gas through the tube assembly.
2. The self-contained, cordless, handheld spray gun of claim 1, wherein the container for holding fluids is adapted to hold paint.
3. The self-contained, cordless, handheld spray gun of claim 1, wherein the source of compressed gas is an internal, electrically driven piston pump.
4. The self-contained, cordless, handheld spray gun of claim 1, wherein the gas nozzle assembly further comprises fan nozzle orifices in intercommunication with the tube assembly.
5. The self-contained, cordless, handheld spray gun of claim 3, wherein the power source and the piston pump are powered with one or more rechargeable batteries.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A grounding-type plug adapter, comprising a substantially rectangular solid being externally provided at a first side with a ground slot, a hot slot, and a neutral slot for a three-pin plug to correspondingly plug thereinto, at a second side with a hot and a neutral blade having respective fixed polarity for correspondingly plugging into hot and neutral slots, respectively, on a general city electricity receptacle, and at a third side with a ground screw for screwing against a grounding wire, a checking device, and a testing device; and internally provided with a protective element electrically connected to said ground screw, said neutral blade, and said checking device, and a resistance connected to and between said checking device and said testing device; whereby said plug adapter is workable only when said hot and said neutral blade are correctly plugged into corresponding hot and neutral slots on the city electricity receptacle.
2. The grounding-type plug adapter as claimed in claim 1, wherein said protective element is selected from the group consisting of a fuse and a low-impedance, low-wattage resistance.
3. The grounding-type plug adapter as claimed in claim 1, wherein said checking device comprises a detecting circuit consisting of a resistance and a neon bulb.
