  FIG. 8 is a cross-sectional view of the power transmission mechanism 101 of the electric vacuum cleaner according to an example of the embodiment of the present invention.

  A metal shaft 802 is insert-molded on the rotating shaft of the pulley 801, and is supported by both ends by a holding member A804 and a holding member B805 in which an oil metal 803 is disposed at the center. Further, a meshing portion A110 is press-fitted into the end portion of the metal shaft 802. Further, a friction between the holding member A 804 and the holding member B 805 and the pulley 801 is reduced by interposing a polyslider washer 806.

  Further, between the pulley 801 and the holding member A804, a dust storage groove 807 is provided by a rib 808 extending from the holding member A804 and a flange 809 provided in a direction opposite to the concave and convex portions of the meshing portion A110. Dust that has entered the transmission mechanism is prevented from entering the sliding portion of the metal shaft 802. Here, the position of the outermost periphery of the flange 809 is lower than the tip of the rib 808.

  Next, operation | movement of the vacuum cleaner in a present Example is demonstrated.

  When the vacuum cleaner user operates the hand switch 304 installed on the handle grip 303 shown in FIG. 3, the electric blower in the vacuum cleaner main body 301 starts operation in the operation mode according to the operated switch. The suction force generated by the electric blower reaches the suction body 306 through the hose body 302 and the extension pipe 305. At the same time, the power supplied from the power lines provided on the hose body 302 and the extension pipe 305 drives the electric motor 205 via a circuit board (not shown).

  When the rotary cleaning body 204 connected by the electric motor 205 and the large pulley 209, the shaft 211, the small pulley 210, the power transmission mechanism 101, and the belt 410 rotates, the brush 105 and the blade which are the cleaning members 107 of the rotary cleaning body 204 104 sucks up dust and dust from the surface to be cleaned.

  Further, since the brush A108 is always in contact with the non-cleaning surface while the rotary cleaning body 204 is rotating, a forward force acts on the suction body 306, and the operation force is reduced. Here, the operating force can be adjusted by changing the density, hardness, height, and the like of the brush A108.

  Further, by applying the brush A108 obliquely and making the brush eyes oblique, when the rotary cleaning body rotates, it is also possible to move the dust toward the center of the rotary cleaning body chamber 212 when the rotary cleaning body rotates. .

  Further, when the mouthpiece 306 is operated forward, the fixed brush 400 on the bottom surface of the mouthpiece 306 falls down to the brush escape portion B406, and when operated backward, the fixed brush 400 falls to the brush escape portion A405. It won't get in between. As a result, it is possible to prevent the fixed brush 400 from being sandwiched between the bottom surface of the mouthpiece 306 and increasing the operating force.

  Further, by setting the brush escape portion A405 and the brush escape portion B406 only before and after the fixed brush 400, even if the brush escape portion A405 and the brush escape portion B406 are provided, the static pressure in the rotary cleaning body storage chamber 212 is not reduced. This is the same as when the escape portion A405 and the brush escape portion B406 are not provided. Thereby, even if the brush escape portion A405 and the brush escape portion B406 are provided, the suction performance does not change.

  However, since the entire circumference of the brush A108 of the rotary cleaning body 204 is composed of the brush A108 as compared with the cleaning member 107, there is a problem in that fiber such as lint, hair, etc. are easily entangled.

  FIG. 7 shows how to remove and attach the rotary cleaning body 204 according to this embodiment for maintenance.

  First, the lower surface side of the mouthpiece 306 is directed upward. An operator's finger is attached to the operation part 220A of the locking member 220, and it is rotated outward from the center side of the suction body 306 to release the engagement between the bearing pressing member 407 and the locking part 220 (A). Then, the bearing pressing member 407 is removed from the lower case 201 (B).

  Next, when the rotary cleaning body 204 is pulled upward, the meshing portion A110 of the rotary cleaning body 204 and the meshing portion B408 of the power transmission mechanism 101 are disengaged and can be detached from the mouthpiece 306 (C).

  Thereby, even when lint or the like adheres to the brush A108 of the rotary cleaning body 204, it is possible to easily remove the rotary cleaning body 204 and easily remove fiber such as lint or hair.

  When the rotary cleaning body is attached, the operation is the reverse of that at the time of removal, the hues of the meshing portion A110 of the rotary cleaning body 204 and the meshing portion B408 of the power transmission mechanism 101 are made uniform, and the rotary cleaning body 206 is connected to the mouthpiece 306. Is inserted. At this time, since the meshing portion A110 of the rotary cleaning body 204 and the bearing stand 111 have different hues, the user can fit the rotary cleaning body 204 to the mouthpiece 306 without making the wrong direction. Next, the bearing pressing member 407 is fitted, and the locking member 220 is locked and engaged.

  As described above, the meshing portion A of the power transmission mechanism 101 existing at the driving side end of the rotary cleaning body 204 and the rotation support member 111 existing on the non-driving side are different colors, and the meshing portion A is detachably connected. Since the meshing portion B408 of the power transmission mechanism 101 provided in the mouthpiece body has the same hue, the meshing portions A and B are meshed by visual judgment or the rotation support member 111 is moved to a predetermined position. Can be easily installed without error.

  Each embodiment of the present invention can be applied not only to a floor moving type vacuum cleaner but also to an upright type or stick type vacuum cleaner. It can be applied not only to motor driven suction bodies but also to air driven systems.
