Fastener-driving tool with an electric power generator
A fastener-driving tool including a housing having an air connector, at least one of a power storage device and an electrical component associated with the housing and an electric motor assembly associated with the housing. The electric motor assembly includes a fan where air is supplied to the housing through the air connector and moves through the housing and contacts the fan to cause the fan to rotate, rotation of the fan causing the electric motor to generate electricity that is directed to the at least one power storage device and the electrical component.
1. A fastener-driving tool comprising:
a housing having an air connector;
an electrical component associated with said housing; and
an electric motor assembly associated with said housing and including a fan and an electric motor,
wherein when air is supplied to said housing through said air connector and moves through said housing and contacts said fan to cause said fan to rotate, rotation of said fan causes said electric motor to generate electricity that is directed to said electrical component.
2. The tool of claim 1 , wherein said electric motor assembly includes: (1) a housing including at least one magnetic coil; and (2) a drive shaft connected to said fan, said drive shaft being rotatably connected to said housing and including at least one magnet, wherein rotation of the fan simultaneously rotates the drive shaft causing the at least one magnet to move relative to said at least one magnetic coil to generate the electricity.
3. The tool of claim 1 , wherein said fan includes at least one fan blade.
4. The tool of claim 1 , wherein said housing includes a handle defining a pressurized air chamber, said electric motor assembly being mounted in said pressurized air chamber.
5. The tool of claim 1 , wherein said electric motor includes a positive electrical cable and a negative electrical cable for transferring the generated electricity to at least one of a power storage device and said electrical component.
6. The tool of claim 1 , wherein the electrical component includes a power storage device.
7. The tool of claim 6 , wherein the power storage device includes a rechargeable battery.
8. The tool of claim 1 , further comprising a processor associated with said housing and in communication with the electric motor assembly, said processor being configured to direct the generated electricity to said electrical component.
9. The tool of claim 8 , further comprising a plurality of electric motor assemblies associated with said housing, wherein each of said electric motor assemblies generates electricity using the air and is in communication with said processor.
10. The tool of claim 1 , wherein the air is pressurized air supplied by a pressurized air source.
11. A fastener-driving tool comprising:
a housing including a handle that defines an interior;
a cylinder at least partially within the housing;
a piston slidably disposed in the cylinder;
a driver blade attached to the piston;
an air connector in fluid communication with the interior of the handle;
an electric motor within the interior of the handle and including one of (1) a magnet and (2) a coil;
a fan including a fan blade, a drive shaft fixedly attached to the fan blade, and the other of (1) the magnet and (2) the coil, wherein the fan is rotatable relative to the electric motor via air received through the air connector, and wherein the fan is positioned within the interior of the handle and adjacent the electric motor such that rotation of the fan relative to the electric motor causes the electric motor to generate electricity; and
an electrical component electrically connected to the electric motor to receive at least some of the generated electricity.
12. The tool of claim 11 , wherein the electrical component includes a power storage device.
13. A fastener-driving tool comprising:
a housing including a handle that defines an interior;
a cylinder at least partially within the housing;
a piston slidably disposed in the cylinder between a pre-drive position and a post-drive position;
a driver blade attached to the piston;
an air connector in fluid communication with the interior of the handle;
an electric motor assembly within the interior of the handle and configured to generate electricity using air received through the air connector during a drive stroke of the piston in which the piston moves from the pre-drive position to the post-drive position; and
an electrical component electrically connected to the electric motor assembly to receive at least some of the generated electricity.
14. The tool of claim 13 , wherein the electric motor assembly includes an electric motor and a fan rotatable relative to the electric motor via the air received through the air connector to generate the electricity.
15. The tool of claim 13 , wherein the electrical component includes a power storage device.
