This is for scraping dust or the like attached to the dust collecting body 33.

Next, the operation of the suction member 10 will be described.

By operating the switch operating portion provided at the hand grip portion 103, and the electric blower in the cleaner body 101 is driven, dust on the floor is sucked into the suction chamber 14 of the suction member 10 together with the air, from the suction port of the suction member 10. 17 is sucked into the cleaner body 101 via the extension pipe 105 and the hose 102 (refer FIG. 1). At this time, the rotating brush 30 is rotated, and the dust removing means 39 is also rotated together with the rotating brush 30. Dust or the like scraped by the rotation of the rotating brush 30 is also sucked. When dust or the like is scraped by the rotation of the rotating brush 30, the wire or the fiber, the hair, or the like is caught around the rotating brush 30, and the rotating brush 30 is locked. In such a state, dust, wadding, and the like may adhere to the front end of the dust absorbing body 33 and become a block, and cannot be removed.

In this case, after the cleaning of the floor is completed, the switch operating portion is turned off, and when the brush removing/detaching handle portion 38 is pulled out from the suction tool 10 in the axial direction of the rotating brush 30, the rotation is pulled out from the opening portion 13.

At the same time, the second dust removing member 41 scrapes off the dust block or the like adhering to the dust collecting body 33 in the suction material 10. When the power is supplied from the switch operating unit, the dust or the like scraped into the suction tool 10 is sucked together with the air, and is sucked into the cleaner body 101 side.

Further, the dust removal operation can be performed without turning off the power. In this case, since the suction of the rotating brush 30 is also performed, it is possible to prevent the garbage or the like adhering to the rotating brush 30 from flying outside the suction member 10. In this way, it is more hygienic.

According to the first embodiment as described above, the first dust removing member 40 of the dust removing means 39 can easily remove the lint, hair, and the like which are caught in the rotating brush 30 without being soiled. Further, since the rotating brush 30 can be pulled out along the side surface of the dust collecting body holding portion 32 or the dust collecting body 33 according to the shape of the first dust removing member 40, the guide member is not guided in the pulling direction (the axial direction of the rotating brush 30). Jitter, which can be easily pulled out and reduces the pull-out force. Further, when the rotating brush 30 is pulled out by the brush attachment/detachment handle portion 38, if the power is supplied, the amount of the attached garbage flowing out to the periphery of the suction member 10 is small, and it is hygienic.

In addition, in the same manner, the second dust removing member 41 can easily remove dust pieces and the like adhering to the dust collecting body 33 without being soiled. When the brush holder 30 is pulled out by the brush attachment/detachment handle portion 38, the spiral cleaning member 32 is formed, and the rotary brush 30 is pulled out while being rotated. Therefore, when the dust collecting body 33 passes through the dust removing means 39, it is in complicated contact with the second dust removing member 41, and dust can be removed more effectively.

Further, in the first embodiment, the second dust removing member 41 is made to contact at least the dust collecting body 33, but the amount of overlap with the dust collecting body 33 may be increased. The more the amount of overlap between the bottom surface of the second dust removing member 41 and the dust collecting body 33 is, the larger the pulling force is, but the stronger the scraping force of the attached garbage.

Further, in the first embodiment, the dust removing means 39 is rotatably attached to the partition wall 37. However, as shown in Fig. 7, the dust removing means 39 and the suction member may be pulled out so that the rotating brush 30 can be pulled out. 10 is formed in one piece. In the case of being formed in this manner, since the dust removing means 39 does not rotate together with the rotating brush 30 when the cleaner body 101 is operated, abrasion of the peripheral portion of the dust removing means 39 caused by the rotation can be prevented, and the components can be reduced. number. Further, the other elements may constitute the dust removing means 39 and may be fixed to the partition wall 37. In this case, the same effect is obtained, and although the number of components is increased, the shape of the mold can be simplified.
