Abstract
A blowing device is equipped with a blowing portion and a holder. The blowing portion has a cylindrical body that stores a rotating body, and includes: a suction inlet arranged on a side surface perpendicular to the axial direction of the cylindrical body; and an exhaust outlet arranged on a part of the peripheral surface of the cylindrical body. The holder has a wall that faces the peripheral surface of the blowing portion with a gap between the wall and the peripheral surface, and holds the blowing portion inside. The holder includes: a suction portion that communicates with the suction inlet; and an exhaust portion that causes the exhaust outlet to communicate with the outside and the gap.
Claims10
A blowing device comprising:
- a blowing portion having a cylindrical body that stores a rotating body, the blowing portion comprising:
- a suction inlet arranged on a side surface perpendicular to an axial direction of the cylindrical body and configured to suction gas;
- and
- an exhaust outlet arranged on a part of a peripheral surface of the cylindrical body and configured to exhaust the gas along a gas exhaust path;
- and
- a holder holding the blowing portion in the holder, the holder comprising:
- a wall that faces the peripheral surface with a gap between the wall and the peripheral surface;
- a suction portion that communicates with the suction inlet;
- and
- an exhaust portion that causes the exhaust outlet to communicate with outside and the gap, wherein:
- the exhaust portion includes a branch portion that protrudes from an edge of the exhaust portion and partially facing the exhaust outlet;
- and
- the branch portion defines a gap exhaust portion and directs the flow of part of the gas that is exhausted from the exhaust outlet through the gap exhaust portion to the gap.
A holder for holding a blowing portion, the holder comprising:
- a wall that faces a peripheral surface of the blowing portion with a gap between the wall and the peripheral surface;
- a suction portion that communicates with a suction inlet of the blowing portion;
- and
- an exhaust portion that causes an exhaust outlet of the blowing portion to communicate with outside and the gap, wherein:
- the exhaust outlet exhausts gas along a gas exhaust path, and
- the exhaust portion includes a branch portion that extends into the holder and protrudes from an edge of the exhaust portion and partially facing the exhaust outlet;
- and
- the branch portion defines a gap exhaust portion and directs the flow of part of the gas that is exhausted from the exhaust outlet through the gap exhaust portion to the gap.
