Abstract
A brush assembly comprises a body having a dirt suction port formed thereon, a cover connected with an upper portion of the body to form a suction passage and a turbine chamber, a turbine mounted in the turbine chamber, and a brush drum being rotated by a rotational force received from the turbine. The turbine chamber and the suction passage are partitioned from each other, and the turbine is rotated by an air drawn in through an air suction port which is separated from the dirt suction port. Accordingly, the turbine is prevented from being clogged by dirt, dust or hair.
Claims17
A brush assembly comprising:
- a body having a dirt suction port formed thereon;
- a cover connected with an upper portion of the body to form a suction passage and a turbine chamber;
- a turbine mounted in the turbine chamber;
- and
- a brush drum being rotated by a rotational force received from the turbine,
- wherein the turbine chamber and the suction passage are partitioned from each other, and the turbine is rotated by an air drawn in through an air suction port which is separated from the dirt suction port.
A brush assembly comprising:
- a suction passage for dirt-entrained air;
- a turbine chamber for clean air;
- a brush drum in fluid communication with said suction passage;
- a turbine mounted in the turbine chamber so that said clean air generates a rotational force on said turbine without exposing said turbine to said dirt-entrained air;
- and
- a force-transmitting member for transmitting said rotational force from said turbine to said brush drum.
A brush assembly comprising:
- a body having a dirt suction port for dirt-laden air;
- a cover having an air suction port for clean air, said cover being removably connected to said body to define a space therebetween;
- a partition member removably mounted in said space to define a first chamber and a second chamber, said first and second chambers being partitioned from one another so that said dirt-laden air passes through said second chamber while said clean air passes through said first chamber;
- a turbine mounted in said first chamber so that said clean air rotates said turbine;
- a brush drum rotatably located in said dirt suction port;
- and
- a force-transmitting member for transmitting rotation of said turbine to said brush drum.
