  The dust collector 8 is provided with a lever 29 and a main body locking means 30. The main body locking means 30 is pivotally fixed by a main body locking means shaft 30a. When the lever 29 is operated, the main body locking means 30 rotates in the locking release direction, the locked state with the main body 1 is released, and the main body 1 can be separated from the main body 1.

  Further, the dust collector 8 is constituted by an assembly of an air passage assembly 9, a swivel assembly 10 and a dust collector assembly 11. As shown in FIGS. 6A and 6B, the air passage assembly 9, the swivel assembly 10, and the dust collector assembly 11 are configured to be separable.

The air passage assembly 9 is an air passage that connects the flow of air between the first swirl chamber 31 and the second swirl chamber 36 of the swirl assembly 10 described later, and is connected to the main body 1 as shown in FIG. The periphery of the air discharge portion 16 is constituted by an air passage portion outer part 27 and an air passage portion inner part 28, and is joined by ultrasonic welding or adhesion. The air passage portion outer part 27 and the air passage portion inner part 28 can be integrally molded, and the basic performance is ensured even by integral molding. However, in order to make the wind flow smoother, the corner portion of the bent portion 28a cannot be made into an R shape due to structural limitations in the case of integral molding, so the corner portion of the bent portion 28a has an R shape. It is desirable to make it from separate parts.
Further, by configuring with separate parts, the air passage portion that connects the flow of the wind between the first swirl chamber 31 and the second swirl chamber 36 has a double structure, so that the sound of the wind flowing leaks to the dust collector 8. In other words, noise is reduced.

  Further, the air passage section assembly 9 is provided with a lever 29 and a main body locking means 30 for releasing the locked state of the main body 1 and the dust collector 8 described above. When the dust collector 8 is locked to the main body 1, when the lever 29 is operated, the main body locking means 30 rotates about the main body locking means rotation shaft 30a in the unlocking direction, and the main body 1 and the dust collector 8 can be separated.

To the suction port 15 of the dust collector 8.

  The dust collector 8 is a cyclone type dust collector. As shown in FIG. 8, the dust collector 8 swirls the air containing dust sucked from the suction port 15 provided in the swivel assembly 10 in the first swirl chamber 31. Due to the centrifugal force obtained by swirling, the air containing dust is separated into large dust, small dust, and air containing finer dust.

  The cyclone type dust collector separates dust and air by centrifugal force, but large dust is pushed toward the wall surface because centrifugal force works more. Thus, the separated large dust passes through the first swirl chamber opening 32 provided in the wall surface of the first swirl chamber 31 and is sent to and stored in the first dust collection chamber a33 provided in the dust collection unit assembly 11.

  The small dust that has not been sent to the first dust collection chamber a33 is separated from the air that has gained momentum at the conical portion of the first swirl chamber 31, and is sent to the first dust collection chamber b34 for storage. The air that has been separated from the small dust and gained momentum in the conical portion of the first swirl chamber 31 passes through the mesh member 24 with finer dust and passes through the connecting air passage 35 of the air passage assembly 9. To the second swirl chamber 36. The mesh member 24 has a plurality of holes having a diameter of about 2 mm so that small dust that is not contained in the first dust collection chamber b34 other than fine dust is not sent to the second swirl chamber 36. It has become.

  Further, fine dust is separated from the air by swirling in the second swirl chamber 36, and the fine dust is stored in the second dust collection chamber 37. The air from which the dust has been separated passes through the air discharge unit 16, is sent from the air suction unit 17 to the main body 1, cools the control board 22 and the like via the electric blower 21, and then the air path (not shown) in the main body 1. 2) to the exhaust pipe 18 (see FIG. 3), and is discharged out of the main body 1 from an exhaust port 19 (see FIG. 3) provided in the exhaust pipe 18.

Next, the operation of the locking means in assembling and dividing the dust collector 8 will be described with reference to FIGS.

When the connecting member 46 moves in the X direction, the connected second locking means 41 also moves in conjunction with the connecting member 46 in the same direction against the biasing force of the biasing means 49. As a result, the hook portion 48 of the second locking means 41 moves in the direction in which the locking is released. Therefore, when the first locking means 40 is unlocked, the second locking means 41 is also unlocked mechanically interlocked.
In this way, even if a plurality of locking means are provided, the locking state of the plurality of locking means can be released by releasing the single locking means, thus ensuring safety and certainty and ease of operation. Are compatible.

  When the first locking means 40 is operated, the second locking means 41 is also released in conjunction with it. However, even if the second locking means 41 is operated, the first locking means 41 is released. The means 40 is not interlocked to release the locked state.

  This is because the second locking means 41 is provided on the handle side and is in a position where it can be operated with the dust collector 8 attached to the main body 1 as shown in FIG. Even if the second locking means 41 is inadvertently operated while the main body 1 is moving, the first locking means 40 is not released, so the dust collector 8 is disassembled and the main body 1 falls. Safety is ensured without such a situation.

  Although the second locking means 41 can be operated, as shown in FIGS. 9 and 10, in consideration of safety, a handle cover 60 is provided and housed in the handle 12 so that a direct release operation can be performed. It is desirable to make the structure impossible.

  As shown in FIG. 9, the swivel unit assembly 10 and the dust collecting unit assembly 11 include a hook portion 50 provided on the swivel unit assembly 10 side and a receiving portion 57 provided on the dust collecting unit assembly 11 side.
