Although various sizes of the battery pack 50 can be attached, a large-capacity battery pack having a substantially rectangular parallelepiped shape is particularly preferable because it can be used for a long time. FIG. 2 and the like show a state in which the battery pack 50 having a substantially rectangular parallelepiped shape is attached. The battery pack 50 is mounted so that its upper surface or lower surface is substantially rectangular and its longitudinal direction (long side direction) is the front-rear direction. That is, the sliding direction of the battery pack 50 is the longitudinal direction of the battery pack 50.

The battery cover 13 covers the battery pack 50 from above. The battery cover 13 is attached to the upper surface 12a of the head cover 12. The battery cover 13 has a gate shape as a whole and extends in the left-right direction, and a battery insertion hole 33 penetrating in the front-rear direction is formed between the battery cover 13 and the upper surface 12a of the head cover 12. The battery pack 50 is inserted into the battery insertion hole 33 from the front side. The battery cover 13 has a configuration in which the lower surface of the battery pack 50, which is turned upside down and faces upward, is covered from above, and the left and right side surfaces of the battery pack 50 are covered from the outside. Cover the main part of the surface. More than half of the total length of the battery pack 50 in the longitudinal direction is covered by the battery cover 13. In the battery pack 50, a predetermined portion on one end side in the longitudinal direction is exposed without being covered by the battery cover 13, and the other end portion in the longitudinal direction is slightly exposed without being covered by the battery cover 13.

The other end of the battery pack 50 in the longitudinal direction may be covered with the battery cover 13 without being exposed. That is, the battery cover 13 may have a shape in which only the front surface is open, and the battery insertion hole 33 may also have a non-penetrating shape. Further, if the operation unit 52 of the battery pack 50 can be operated, the battery cover 13 may cover the substantially overall length of the battery pack 50 in the longitudinal direction. A power cord 34 is detachably attached to the rear surface of the battery cover 13. Therefore, even when the battery pack 50 is not attached or the battery pack 50 is out of battery power, the power cord 34 can supply electric power to the motor 6 to perform the work.

The upper surface 13a of the battery cover 13 is a substantially flat surface, and the handle 14 is provided on the upper surface 13a. The handle 14 has a U-shape or a U-shape, and both end portions 14a thereof are rotatably supported by the upper surface 13a of the battery cover 13. Specifically, the handle 14 rotates about a straight line connecting both end portions 14a, and extends over a predetermined angle range between the unused position where the handle 14 is not used and the used position where the handle 14 is used. Rotate. In the present embodiment, the handle 14 rotates about the axis in the left-right direction. That is, the handle 14 rotates back and forth.

In the non-use position, as shown in FIG. 1 and the like, the handle 14 is in a sideways posture in which it is tilted substantially horizontally, and in the use position, it is in a standing posture in which it is raised substantially vertically upward. A groove 35 having a shape corresponding to the shape of the handle 14 is formed on the upper surface 13a of the battery cover 13, and the handle 14 fits into the groove 35 at an unused position. Therefore, in the unused position, the handle 14 does not protrude upward from the upper surface 13a of the battery cover 13, and the amount of protrusion thereof is substantially 0. On the contrary, since the handle 14 is in the upright posture at the use position, the amount of protrusion from the upper surface 13a of the battery cover 13 becomes large and it becomes easy to grip. When not in use, the handle 14 is tilted to the rear side, and when in use, the handle 14 is rotated to the front side to take an upright posture.

The handle 14 is located at the center in the long axis direction along the short axis direction of the dust collector. Therefore, the handle 14 extends in a direction orthogonal to the sliding direction of the battery pack 50 in a plan view. Further, as shown in FIG. 8, the handle 14 straddles the battery pack 50 in the lateral direction thereof, and both end portions 14a of the handle 14 are located on the left and right sides of the battery pack 50.

The filter 15 is attached to the lower side of the main body housing. A tubular float holder 16 is attached to the lower surface of the motor base 10 so as to be suspended, and a float 17 is provided at the lower part inside the float holder 16. A through hole (not shown) is formed on the peripheral surface of the float holder 16, and the float holder 16 is attached so as to cover the outside of the float holder 16 with a tubular filter 15. A lid-shaped filter lock 18 is detachably attached to the lower end of the float holder 16, and the filter 15 can be replaced by removing the filter lock 18. The filter 15 is located at a predetermined distance from the inner peripheral surface of the tank 2 toward the inside.

The flow of the dust collecting wind is shown by arrows in FIGS. 7 and 9. The dust collecting air enters the inside of the tank 2 from the hose connection port 4, passes through the filter 15 and the float holder 16 inside, and reaches the dust collecting fan 8, and then the motor base 10, the motor cover 11, and the head cover 12 It rises inside the hose and is discharged to the outside from the exhaust port 25.

In the dust collector configured as described above, since the motor 6 and the battery pack 50 are arranged one above the other, the horizontal dimension of the dust collector can be suppressed. In particular, since the battery pack 50 having a substantially rectangular parallelepiped shape is slidly mounted along the longitudinal direction so that the longitudinal direction thereof is substantially horizontal, the battery pack 50 having a substantially rectangular parallelepiped shape and a large capacity is mounted. Can also suppress horizontal dimensions. Further, since the longitudinal direction of the battery pack 50 having a substantially rectangular parallelepiped shape is substantially horizontal, the vertical dimension can be suppressed.

Then, since the main part of the battery pack 50 is covered by the battery cover 13, the battery pack 50 is less likely to get wet even if it rains. Further, since the handle 14 is provided on the upper surface 13a of the battery cover 13, the handle 14 can be gripped and easily carried. Moreover, since the handle 14 can be kept tilted rearward during the dust collecting work or when hanging on the shoulder, the handle 14 is less likely to get in the way. Further, since the handle 14 is tilted to the rear side instead of the front side, the handle 14 does not get in the way when the battery pack 50 is attached / detached. In particular, the handle 14 is not configured to fall forward or backward, but is configured to fall only to the rear side, and tilting to the front side is restricted. Therefore, the handle 14 accidentally falls to the front side and interferes with the attachment / detachment of the battery pack 50. There is no such thing as becoming. Further, since the power cord 34 is also provided on the side opposite to the insertion side of the battery pack 50, the power cord 34 does not get in the way when the battery pack 50 is attached or detached.

Further, since the dust collector has a rectangular shape or an elliptical shape with rounded corners in a plan view and the shoulder strap extends along the long axis direction of the dust collector, when the dust collector is hung on the shoulder using the shoulder strap. The left and right sides, which are the sides in the minor axis direction of the dust collector, face the worker's body, so that the dust collector can easily follow the body and therefore can be easily carried. Since the battery pack 50 is slidably mounted along the long axis direction of the dust collector, the battery pack 50 having a substantially rectangular parallelepiped shape can be arranged by efficiently utilizing the long dimension of the dust collector in the long axis direction, and the horizontal dimension of the dust collector. Can be suppressed.

Further, since the battery pack 50 is mounted from the operator side of the dust collector in which the main switch 23 and the remaining amount display unit 24 are arranged, the battery pack 50 can be easily attached and detached. Specifically, the work can be started immediately by mounting the battery pack 50 and operating the main switch 23. Even when removing the battery pack 50, the remaining battery level can be checked on the remaining amount display unit 24 and the main switch 23 can be operated to remove the battery pack 50, which can be smoothly performed as a series of operations. it can.
