A portable cleaner includes: a housing; a motor; a fan; a dust filter; and an exhaust regulating unit. The housing is formed with an intake port, an exhaust port, and a blower port. The housing defines an air passage providing a communication between the intake port, the exhaust port, and the blower port. The fan is disposed in the air passage and rotationally driven by the motor. The fan is configured to draw air into the air passage through the intake port and to exhaust the air from the air passage through at least one of the exhaust port and the blower port while rotating. The dust filter is disposed in the air passage at a position between the intake port and the fan. The exhaust regulating unit is provided at the housing and configured to regulate an amount of the air exhausted from the air passage through the blower port.

The portable cleaner as claimed in claim 1, wherein the air is drawn into the air passage through the intake port in an intake direction; wherein the intake port is positioned in the air passage at an upstream side of the dust filter in the intake direction;wherein the housing is further formed with an air inlet part that is configured to be in direct communication with a part of the air passage that is positioned at a downstream side of the dust filter in the intake direction, the housing including an inlet gating unit disposed at a position confronting the air inlet part and configured to regulate an amount of air drawn in the air passage through the air inlet part; andwherein the housing further includes an air inflow regulating unit disposed in the air passage at a position between the intake port and the fan and configured to regulate an amount of air drawn in the air passage through the intake port. 7. The portable cleaner as claimed in claim 1, wherein the exhaust regulating unit is configured to pivotally move with respect to the housing, the exhaust regulating unit being configured to guide exhaust air through the exhaust port so that the air is expelled in a direction away from a cleaning target. 8. A portable cleaner comprising: a motor;a fan attached to the motor;a housing defining an internal space and having a front portion and a rear portion, the motor being accommodated in the internal space;an intake port formed in the front portion of the housing;a dust filter accommodated in the internal space;a blower port formed in the front portion of the housing;a battery pack provided at the rear portion of the housing; anda handle provided at the housing and configured to be held by a user. 9. The portable cleaner as claimed in claim 8, wherein an amount of air expelled from the blower port is configured to be regulated. 10. A portable cleaner comprising: a motor;a fan attached to the motor;a housing accommodating the motor therein;a first air inlet port formed in the housing;a dust filter accommodated in the housing at a position between the first air inlet port and the fan;a blower port formed in the housing;a battery pack provided at the housing; anda second air inlet port formed in the housing at a position between the dust filter and the fan. 11. The portable cleaner as claimed in claim 10, wherein air inflow through the first air inlet port is configured to be regulated. 12. A portable cleaner comprising: a motor;a fan attached to the motor;a housing accommodating the motor therein;an intake port formed in the housing;a dust filter accommodated in the housing;a blower port formed in the housing and from which an air is expelled to blow away dust; anda battery pack provided at the housing. 13. A portable cleaner comprising: a motor;a fan attached to the motor;a housing accommodating the motor therein and having a rear portion, the housing defining a passage spatially continuous with the fan;an intake port formed in the housing;a dust filter accommodated in the housing;a battery pack provided at the rear portion;a handle provided at the housing and configured to be held by a user; anda blower port formed in the housing and in communication with the passage. 14. A portable cleaner configured to clean a cleaning target comprising: a housing formed with an intake port and an exhaust port, the housing defining an air passage providing a communication between the intake port and the exhaust port;a motor accommodated in the housing;a fan disposed in the air passage and configured to be rotationally driven by the motor, the fan being configured to draw air into the air passage through the intake port and to exhaust the air from the air passage through the exhaust port while rotating; anda dust filter disposed in the air passage at a position between the intake port and the fan,wherein the air drawn in the air passage is exhausted from the air passage through the exhaust port in a direction away from the cleaning target. 15. The portable cleaner as claimed in claim 14, wherein the housing is formed with a blower port in communication with the intake port and through which at least part of the air drawn in the air passage through the intake port is expelled, the portable cleaner further comprising a switching unit configured to selectively switch between a first mode for allowing the air drawn in the air passage through the intake port to be exhausted from the air passage through the exhaust port and a second mode for allowing the air drawn in the air passage through the intake port to be expelled from the air passage through the blower port. 16.
