The operation of the suction tool of the electric vacuum cleaner in the present embodiment configured as described above will be described.
First, the case where the rotary cleaning body 10 is attached to the suction tool main body 1 will be described.
A coil spring 31 is attached to the bearing recess 21 formed on the side surface of the suction cover 5 of the suction tool body 1, and the rotary cleaning body is inserted into the bearing member mounting hole 22 formed on one side surface of the suction cover 5 of the suction tool body 1. 10 is inserted from the shaft 12 side.

  Then, immediately before the shaft 12 of the rotary cleaning body 10 passes through the coil spring 31 and reaches the bearing recess 21, the bearing member 13 of the rotary cleaning body 10 is inserted into the bearing member mounting hole 22 of the suction cover 5 as shown in FIG. 1. When facing, the pair of locking protrusions 16, 16 of the bearing member 13 are aligned with the body insertion mark 30 a around the bearing member mounting hole 22, and the bearing member 13 resists the biasing force of the coil spring 28. When pushed in, the pair of locking projections 16 of the bearing member 13 engage with the locking insertion groove 23 and the positioning projection 17 is pushed in with the positioning insertion groove 24 engaged.

When the push-in is continued, the pair of locking projections 16 advances through the tapered annular groove 25 of the bearing member mounting hole 22 and comes into contact with the fitting projection 26, and the positioning projection 17 reaches the annular groove 27, and is pushed further. It becomes impossible.
Therefore, the handle 19 of the bearing member 13 is picked with a finger, and the bearing member 13 is rotated toward the “closed” side fixing mark 30 b around the bearing member mounting hole 22.

As a result, one of the pair of locking projections 16 of the bearing member 13 moves inward to get over the fitting projection 26 of the bearing member mounting hole 22, and the fitting projection 26 is fitted between the pair of locking projections 16. By the way, another positioning projection 17 abuts against the stopper projection 28 of the bearing member mounting hole 22 to prevent the rotation, and the bearing member 13 is fixedly attached to the bearing member mounting hole 22 in a locked state.
When rotating the bearing member 13, the handle portion 19 is picked and rotated by a finger, but a coin may be inserted into the coin groove 19 a of the handle portion 19 and rotated.

  At this time, the support shaft 12 of the rotary cleaning body 10 is rotatably supported by a bearing recess 21 formed on the side surface of the suction cover 5, and the bearing member 13 fixed to the bearing member mounting hole 22 in a locked state is rotated. Since the cleaning body 10 is rotatably attached to the support shaft 12, the rotary cleaning body 10 is rotatably attached to the side surface of the suction cover 5.

  When the vacuum cleaner is operated in a state where the rotary cleaning body 10 is attached to the suction tool body 1 in this way, wind is sucked into the suction tool body 1 from the front end side of the suction tool body 1 and the suction port 6. Then, when these winds hit the blade 14 of the rotary cleaning body 10, the rotary cleaning body 10 rotates.

When the rotary cleaning body 10 is removed, as shown in FIGS. 5 and 6, the handle portion 19 of the bearing member 13 is picked with a finger, and the bearing member 13 is inserted into the main body insertion mark 30 a around the bearing member mounting hole 22. Rotate until it matches.
Then, after one of the pair of locking projections 16 moves inward to overcome the fitting projection 26 of the bearing member mounting hole 22 and the bearing member 13 is unlocked with respect to the bearing member mounting hole 22, the pair of locking projections 16 is released. 16 advances through the tapered annular groove 25 to reach the lock insertion groove 23, and the stopper projection 28 also comes to the position of the positioning insertion groove 24.

Thereafter, due to the urging force of the coil spring 31, the pair of locking projections 16 move in the locking insertion groove 23, and the stopper projection 28 also moves in the positioning insertion groove 24, as shown in FIGS. Thus, the bearing member 13 of the rotary cleaning body 21 jumps out of the bearing member mounting hole 22.
Therefore, the rotary cleaning body 10 is removed from the suction cover 5, that is, the suction tool body 1 by pinching the handle 19 of the bearing member 13 of the rotary cleaning body 10 with a finger and pulling it out from the bearing member mounting hole 22. be able to.

Thus, by rotating and pulling out the bearing member 13 of the rotary cleaning body 10, the rotary cleaning body 10 can be removed from the suction tool main body 1, so that the blade 14 and the flocks 15 of the rotary cleaning body 10 are not touched. Moreover, since the rotary cleaning body 10 can be easily removed from the suction tool main body 1 with one finger, the finger is not soiled. Further, since it is not necessary to remove the suction cover 5 as in the prior art, it can be easily removed without much trouble and is convenient.
Moreover, since it is not necessary to have the blade 14 at the time of attachment / detachment of the rotary cleaning body 10, the blade 14 does not extend or remove.

  Further, the fitting protrusion 26 of the bearing member mounting hole 22 formed in the suction cover 5 is fitted between the pair of lock protrusions 16 of the bearing member 13 so that the bearing member 13 is securely locked in the bearing member mounting hole 22. Since the bearing member 13 does not rotate within the bearing member mounting hole 22 even when the suction tool main body 1 is brought into contact with the wall or the like with a strong force, the bearing member 13 is not detached and can be used safely. In addition, the vibration due to the rotation of the rotary cleaning body 10 can be suppressed, and a convenient vacuum cleaner can be provided.
