Power head for vacuum systems
First Claim
1. A power head for use with a vacuum system comprising:
- a main body assembly comprisinga main housing defininga main chamber defining a main inlet and a main outlet, andfirst and second main contacts supported by the main housing and operatively connected to a power supply;
a brush assembly comprisinga brush housing defining a brush chamber, a brush inlet, and a brush outlet,a brush defining an axle chamber,first and second bearings arranged to support the brush within the brush chamber for rotation relative to the brush housing,a motor comprising a motor shaft, where the motor is supported by the brush housing such that the motor shaft is arranged within the axle chamber;
a motor gear assembly arranged within the axle chamber and operatively connected between the motor shaft and the brush such that operation of the motor causes rotation of the brush assembly relative to the brush housing;
first and second brush contacts supported by the brush housing and operatively connected to the motor;
a latch system for detachably attaching the brush assembly to the main body assembly such thatthe main inlet portion of the main chamber is in fluid communication with the brush outlet, andthe first and second main contacts are in contact with the first and second brush contacts;
wherein when the vacuum system is operatively connected to the main housing and the latch system detachably attaches the main housing to the brush housing,the vacuum system draws air through the brush inlet, the brush chamber, the brush outlet, the main inlet, the main chamber, and the main outlet; and
the power supply supplies power to the motor such that the motor rotates the brush assembly relative to the brush housing.

Abstract
A power head for use with a vacuum system. The power head comprises a main body assembly, a brush assembly, and a latch system. The latch system detachably attaches the brush assembly to the main body assembly such that a main inlet portion of the main chamber is in fluid communication with a brush outlet and the battery is operatively connected to the motor. When the vacuum system is detachably attached to the main housing and the latch system detachably attaches the main housing to the brush housing, the vacuum system draws air through a brush inlet, a brush chamber, the brush outlet, the main inlet, a main chamber, and a main outlet and the battery supplies power to the motor such that the motor rotates the brush assembly relative to the brush housing.

1. A power head for use with a vacuum system comprising:
-
a main body assembly comprising a main housing defining a main chamber defining a main inlet and a main outlet, and first and second main contacts supported by the main housing and operatively connected to a power supply; a brush assembly comprising a brush housing defining a brush chamber, a brush inlet, and a brush outlet, a brush defining an axle chamber, first and second bearings arranged to support the brush within the brush chamber for rotation relative to the brush housing, a motor comprising a motor shaft, where the motor is supported by the brush housing such that the motor shaft is arranged within the axle chamber; a motor gear assembly arranged within the axle chamber and operatively connected between the motor shaft and the brush such that operation of the motor causes rotation of the brush assembly relative to the brush housing; first and second brush contacts supported by the brush housing and operatively connected to the motor; a latch system for detachably attaching the brush assembly to the main body assembly such that the main inlet portion of the main chamber is in fluid communication with the brush outlet, and the first and second main contacts are in contact with the first and second brush contacts; wherein when the vacuum system is operatively connected to the main housing and the latch system detachably attaches the main housing to the brush housing, the vacuum system draws air through the brush inlet, the brush chamber, the brush outlet, the main inlet, the main chamber, and the main outlet; and the power supply supplies power to the motor such that the motor rotates the brush assembly relative to the brush housing. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A method of directing air and debris into a vacuum system comprising:
-
providing a main body assembly comprising a main housing defining a main chamber defining a main inlet and a main outlet, and first and second main contacts supported by the main housing and operatively connected to a power supply; providing a brush assembly comprising a brush housing defining a brush chamber, a brush inlet, and a brush outlet, a brush defining an axle chamber; first and second bearings arranged to support the brush within the brush chamber for rotation relative to the brush housing, and a motor comprising a motor shaft, where the motor is supported by the brush housing such that the motor shaft is arranged within the axle chamber; a motor gear assembly arranged within the axle chamber and operatively connected between the motor shaft and the brush such that operation of the motor causes rotation of the brush assembly relative to the brush housing; detachably attaching the brush assembly to the main body assembly such that the main inlet portion of the main chamber is in fluid communication with the brush outlet, and the first and second main contacts are in contact with the first and second brush contacts; operating the vacuum system to draw air through the brush inlet, the brush chamber, the brush outlet, the main inlet, the main chamber, and the main outlet; and connecting the power supply to the motor such that the motor rotates the brush assembly relative to the brush housing. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A vacuum system comprising:
-
a vacuum source; a hose connected to the vacuum source; a handle connected to the hose; an extension tube connected to the handle; a power head comprising a main body assembly comprising a main housing defining a main chamber defining a main inlet and a main outlet, and a battery chamber, and a battery arranged in the battery chamber; a brush assembly comprising a brush housing defining a brush chamber, a brush inlet, and a brush outlet, a brush rotatably supported within the brush chamber, and a motor arranged to rotate the brush assembly relative to the brush housing; a latch system for detachably attaching the brush assembly to the main body assembly such that the main inlet portion of the main chamber is in fluid communication with the brush outlet, and the battery is operatively connected to the motor; wherein when the extension tube is detachably attached to the main housing and the latch system detachably attaches the main housing to the brush housing, the vacuum source draws air through the brush inlet, the brush chamber, the brush outlet, the main inlet, the main chamber, the main outlet, the extension tube, the handle, and the hose; and the battery supplies power to the motor such that the motor rotates the brush assembly relative to the brush housing. - View Dependent Claims (18)
