연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

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, andfirst 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, 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; andthe power supply supplies power to the motor such that the motor rotates the brush assembly relative to the brush housing. 2. A power head as recited in claim 1, further comprising: a battery chamber is arranged between a rear portion of the main chamber and the main inlet, where the battery chamber is arranged between a first side portion of the main chamber and a second side portion of the main chamber; anda battery arranged within the battery chamber and operatively connected to the first and second main contacts. 3. A power head as recited in claim 2, in which: the main chamber further defines a central portion; andthe battery chamber is arranged above at least a portion of the central portion. 4. A power head as recited in claim 1, in which: the main chamber further defines a central portion; anda battery chamber is arranged above at least a portion of the central portion. 5. A power head as recited in claim 1, in which the motor gear assembly comprises: a drive gear operatively connected to the motor shaft;a ring gear formed on an interior surface of the brush; anda plurality of planetary gears; whereinthe planetary gears transfer rotation of the drive gear to the ring gear. 6. A power head as recited in claim 1, in which the ring gear is rigidly secured to the interior surface of the brush. 7. A power head as recited in claim 1, in which: the brush comprises a brush axle defining the axle chamber and bristles outwardly extending from the brush axle; andat least a portion of the motor is arranged within the axle chamber. 8. A power head as recited in claim 1, in which: the brush comprises a brush axle defining the axle chamber and bristles outwardly extending from the brush axle; andthe motor is supported within the axle chamber. 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, andfirst 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, anda 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, andthe 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; andconnecting the power supply to the motor such that the motor rotates the brush assembly relative to the brush housing. 10. A method as recited in claim 9, in which the step of providing the main housing comprises the steps of: arranging a battery chamber between a rear portion of the main chamber and the main inlet;arranging the battery chamber between a first side portion of the main chamber and a second side portion of the main chamber;arranging a battery within the battery chamber; andoperatively connecting the battery to the first and second main contacts. 11.

A method as recited in claim 10, in which the step of providing the motor gear assembly comprises the step of rigidly securing the ring gear to the interior surface of the brush. 13. A method as recited in claim 9, in which the step of providing the main housing comprises the step of arranging a battery chamber above at least a portion of a central portion of the main chamber. 14. A method as recited in claim 9, in which the step of providing the motor gear assembly comprises the steps of: operatively connecting a drive gear to the motor shaft;forming a ring gear on an interior surface of the brush;arranging a plurality of planetary gears to transfer rotation of the drive gear to the ring gear. 15. A method as recited in claim 9, in which the step of providing the brush comprises the step of providing a brush axle defining the axle chamber and bristles outwardly extending from the brush axle, the method further comprising the step of arranging at least a portion of the motor within the axle chamber. 16. A method as recited in claim 9, in which the step of providing the brush comprises the step of providing a brush axle defining the axle chamber and bristles outwardly extending from the brush axle, the method further comprising the step of arranging the motor within the axle chamber. 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, anda battery chamber, anda 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, anda 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, andthe 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; andthe battery supplies power to the motor such that the motor rotates the brush assembly relative to the brush housing. 18. A vacuum system as recited in claim 17, further comprising a charger, where the latch system further detachably attaches the brush assembly to the charger to charge the battery.
