Abstract: A backpack dust collector includes a housing. The housing includes: a suction port; a dust collecting chamber connected to the suction port and configured to accommodate a dust collecting bag; a motor chamber connected to the dust collecting chamber and accommodating a fan and a motor; an exhaust port through which air from the motor chamber is discharged; first and second battery openings; and first and second battery receiving portions respectively corresponding to the first and second battery openings. At least part of the first battery opening is formed on a left side surface of the housing, and at least part of the second battery opening is formed on a right side surface of the housing.

Abstract: A backpack dust collector includes a housing, a slit portion, and a noise-absorbing member. The housing includes a suction port, a dust collecting chamber, a motor chamber, and an exhaust port. The dust collecting chamber is connected to the suction port and configured to accommodate a dust collecting bag. The motor chamber is connected to the dust collecting chamber and accommodates a fan and a motor. Through the exhaust port, air from the motor chamber is discharged. The slit portion is disposed in a flow path between the motor chamber and the exhaust port and includes at least one slit-shaped vent through which air from the motor chamber passes. The noise-absorbing member is disposed in at least part of a flow path between the vent and the exhaust port.

Abstract: A dust collector cools a controller. The dust controller includes a body housing, a motor located inside the body housing, a fan rotatable by the motor, a controller that controls the motor, and a thermal insulator between the motor and the controller. The thermal insulator defines a flow channel through which an airflow generated by the fan passes.
