Abstract

An inflator tool includes a handle portion extending between a battery receiving portion and a tool head portion. The handle portion defines a longitudinal axis. The tool head portion includes an air inlet, a compression chamber, and an air outlet. A motor is at least partially supported within the handle portion and includes an output shaft. The air inlet defines an inlet axis, and the air outlet defines an outlet axis. The longitudinal axis is disposed at an oblique angle relative to each of the inlet axis and the outlet axis.

First claim

What is claimed is:

1. An inflator tool comprising:
a handle portion extending between a battery receiving portion and a tool head portion, the handle portion defining a longitudinal axis, and the tool head portion including an air inlet, a compression chamber, and an air outlet; and
a motor at least partially supported within the handle portion and including an output shaft,
wherein the air inlet defines an inlet axis, and the air outlet defines an outlet axis,
wherein the longitudinal axis is disposed at an oblique angle relative to each of the inlet axis and the outlet axis,
wherein the tool includes an outer housing forming at least the tool head portion,
wherein the air inlet is formed on a surface of the outer housing, and
wherein the air inlet is configured to receive air from a surrounding environment, and all of the air received through the air inlet is configured to directly enter the compression chamber.

2. The inflator tool of claim 1 , wherein the output shaft defines a motor axis, the motor axis parallel with the inlet axis, and wherein the motor axis is substantially orthogonal to the outlet axis.

3. The inflator tool of claim 1 , wherein the inlet axis is substantially orthogonal to the outlet axis.

4. The inflator tool of claim 1 , further comprising an air driving assembly including a rotor supported within the tool head portion, the motor operatively coupled to the rotor for driving pressurized airflow from the air inlet to the air outlet, wherein the compression chamber extends around the air driving assembly.

5. The inflator tool of claim 4 , wherein the tool head portion includes an arcuate body and an outlet body extending radially away from the arcuate body, the arcuate body delimiting the compression chamber extending concentrically about the rotor.

6. The inflator tool of claim 1 , wherein the compression chamber includes a spirally shaped delimiting wall extending around the compression chamber, the wall having a center defined by a center of a rotor positioned within the compression chamber.

7. The inflator tool of claim 6 , further comprising a circumferential clearance defined between an outer periphery of the rotor and the wall, the circumferential clearance in fluid communication with the air outlet.

8. The inflator tool of claim 6 , further comprising a radius defined by the wall, the radius increasing along a circumferential direction of the wall to form a circumferential clearance.

9. The inflator tool of claim 8 , wherein the rotor includes channels defined between adjacent blades of the rotor, the channels extending from the center towards an outer periphery of the rotor, the channels fluidly communicating the air inlet with the circumferential clearance.

10. An inflator and deflator tool comprising:
a handle portion extending between a battery receiving portion and a tool head portion, the battery receiving portion positioned at an end of the handle portion;
a motor at least partially supported within the handle portion and including an output shaft defining a motor axis; and
an air driving assembly supported within a compression chamber of the tool head portion, the air driving assembly configured to drive air from an air inlet, disposed on a top surface of the tool, into the compression chamber and out of an air outlet formed on the tool head portion,
wherein the air inlet extends along a first direction that is collinear with the motor axis, and the air outlet extends along a second direction substantially orthogonal to the first direction,
wherein the tool includes an outer housing forming at least the tool head portion, the outer housing having the top surface, and
wherein the handle portion defines a longitudinal axis, the longitudinal axis disposed at an oblique angle relative to each of the first direction and the second direction.

11. The inflator and deflator tool of claim 10 , wherein the tool head portion includes an arcuate body and an outlet body extending radially away from the arcuate body, the arcuate body including the air inlet and the compression chamber, the outlet body including the air outlet.

12. The inflator tool of claim 11 , wherein the air inlet includes a cylindrical inlet member having a bore extending therethrough, the cylindrical inlet member defining the first direction, and wherein the outlet body defines the second direction.

13. The inflator tool of claim 1 , wherein the tool head portion includes an arcuate body and an outlet body extending radially away from the arcuate body, the arcuate body including the air inlet and the compression chamber, the outlet body including the air outlet.
