Abstract

A compact inflator is described herein. The inflator may include a rotatable drum, an air pump disposed within the drum, a fixed securing mechanism that provides structural support to, and enables rotation of, the drum, a power supply, and an electric power transmission mechanism. The drum may draw in and let out a hose. The hose may have a first end and a second end, the first end having a connection mechanism that connects the hose to an inflatable object. The air pump may be connected to the second end of the hose. The power supply may provide power to the motor, and may be coupled to the pump or the power supply. The power transmission mechanism may include a slip ring assembly or a pair of parallel inductors, one which rotates with the drum about the other.

First claim

We claim:

1. An inflator, comprising:
a rotatable drum that draws in and lets out a hose, the hose comprising a first end and a second end, the first end having a connection mechanism that connects the hose to an inflatable object;
an air pump disposed within the drum and connected to the second end of the hose;
a housing that provides structural support to, and enables rotation of, the drum;
a power supply that provides power to the pump; and
an electric power transmission mechanism electrically coupled to one or more of the pump or the power supply between the pump and the power supply, the power transmission mechanism comprising a slip ring assembly;
the pump comprising a motor, the motor movably disposed within the drum, wherein the motor comprises a pinion, and wherein the pinion moves between engagement with a pump gear and a drum rack, wherein the motor rotates the drum at least to draw in the hose.

2. The invention of claim 1 , wherein the motor rotates the drum to draw in and let out the hose.

3. The invention of claim 2 , further comprising a pawl mechanism to secure the drum, to prevent rotation of the drum, as the pinion engages the pump gear.

4. The invention of claim 1 , further comprising a second motor to rotate the motor between engagement with the pump gear and the drum rack.

5. The invention of claim 1 , wherein the inflator is adapted to communicate with and receive commands from a wireless control device.

6. The invention of claim 1 , wherein the inflator is adapted to communicate with a cloud network.

7. The invention of claim 1 , wherein the power supply comprises a battery.

8. An inflator, comprising:
a rotatable drum that draws in and lets out a hose, the hose comprising a first end and a second end, the first end having a connection mechanism that connects the hose to an inflatable object;
an air pump disposed within the drum and connected to the second end of the hose;
a housing that provides structural support to, and enables rotation of, the drum;
a power supply that provides power to the pump; and
an electric power transmission mechanism electrically coupled to one or more of the pump or the power supply between the pump and the power supply, the power transmission mechanism comprising a slip ring assembly;
the pump comprising a motor, the motor movably disposed within the drum, wherein the motor comprises a motor gear, and wherein the motor gear moves between engagement with a pump gear and a drum gear, wherein the motor rotates the drum at least to draw in the hose.

9. The invention of claim 8 , wherein the motor rotates the drum to draw in and let out the hose.

10. The invention of claim 8 , further comprising a pawl mechanism to secure the drum, to prevent rotation of the drum, as the motor gear engages the pump gear.

11. The invention of claim 8 , further comprising a second motor to rotate the motor between engagement with the pump gear and the drum rack.

12. The invention of claim 8 , wherein the inflator is adapted to communicate with and receive commands from a wireless control device.

13. The invention of claim 8 , wherein the inflator is adapted to communicate with a cloud network.

14. The invention of claim 8 , wherein the power supply comprises a battery.
