Furthermore, as shown in FIG. 8, when only the suction tool 4 is inserted in the insertion part 12 of the dust collection part 11, it can be used as a handy cleaner.

Next, when the cleaner body 1 is mounted on the charging stand 5, a mechanism in which both are electrically connected will be described with reference to FIGS.
9 is a vertical cross-sectional view of the vacuum cleaner main body and the charging stand according to the embodiment of the present invention in a separated state, and FIG. 10 is just before the cleaner main body of FIG. 9 is placed on the charging stand. FIG. 11 is a longitudinal sectional view when the cleaner body of FIG. 10 is placed on the charging stand, and FIG. 12 is a longitudinal sectional view when the cleaner body is separated from the state of FIG. It is.

  As shown in FIG. 9, the vacuum cleaner main body 1 includes a first convex portion 1b and a second convex portion 1d that protrude downward from the bottom surface 1a, and a first portion that is provided at the tip of the first convex portion 1b. And a terminal 1c. The charging stand 5 has a first recess 57 and a second recess 58 provided in the rear upper surface portion 51 c, and a second terminal 57 a provided at the bottom of the first recess 57. The 1st convex part 1b is a groove-shaped convex part by which upper part was opened. The side surface of the second convex portion 1d on the first convex portion 1b side is opened.

  The tip of the latch 20 is inserted into the second convex portion 1d, and the claw portion 20a protrudes from the opening. The latch 20 is configured to rotate in the width direction of the cleaner body 1 with a support base 25 provided on the bottom surface 1a of the cleaner body 1 as a fulcrum. A joint portion 22 that operates in the width direction of the cleaner body 1 according to the rotation of the latch 20 is provided at the upper end portion of the latch 20.

  Slit-shaped long holes 57b and 58a are provided on one side surface of the first concave portion 57 and the second concave portion 58 (the left side surface when the charging base 5 is viewed from the front). A part of the plate-shaped shutter 59 passes through these elongated holes 57b and 58a so as to be freely inserted and removed. That is, a part of the shutter 59 in the first recess 57 covers the second terminal 57a in the first recess 57 by the biasing force of the spring 59a, and a part of the shutter 59 in the second recess 58 is The vacuum cleaner main body 1 is inserted into the second concave portion 58 with a gap so that the tip of the second convex portion 1d is inserted.

  An interlocking member 17 a extending in the vertical direction is connected to the main body separation button 17 described above, and a spring 17 b is provided inside the main body separation button 17. When the main body separation button 17 is pushed downward against the urging force of the spring 17b, the joint portion 22 is pushed toward the first convex portion 1b by the projection 17c of the interlocking member 17a. At this time, the latch 20 is rotated clockwise around the support base 21 in conjunction with the joint portion 22, and the claw portion 20 a is moved into the second recess 58.

  As shown in FIG. 10, when the cleaner body 1 is mounted on the charging stand 5, the shutter 59 is resisted against the biasing force of the spring 59 a by the second convex portion 1 d inserted into the second concave portion 58. While being pushed out from the long hole 58a of the second concave portion 58, it is pulled out from the long hole 57b of the first concave portion 57 to open the first concave portion 57. And as shown in FIG. 11, when the cleaner main body 1 is mounted on the charging stand 5, the 1st convex part 1b of the vacuum cleaner main body 1 is inserted in the 1st recessed part 57, and 1st terminal 1c and 2nd The terminal 57 a is electrically connected, and the second protrusion 1 d is inserted into the second recess 58.

  On the other hand, when the cleaner body 1 is placed on the charging stand 5, the claw portion 20 a of the latch 20 is locked to the rear upper surface portion 51 c of the charging stand 5, and the cleaner body 1 is attached to the charging stand 5. It becomes a state. Further, when the main body separation button 17 is pushed downward, the joint portion 22 is pushed toward the first convex portion 1b by the projection 17c of the interlocking member 17a. At this time, the latch 20 is rotated clockwise with the support base 21 as a fulcrum in conjunction with the joint portion 22, and the claw portion 20a moves into the second recess 58, so that the cleaner body 1 is attached to the charging base 5. Is released (see FIG. 12).

  As described above, according to the embodiment, even if the power cord 53 of the charging base 5 is plugged into the outlet and the second terminal 57a is energized, the second terminal 57a is installed in the first recess 57. The shutter 59 is covered above the second terminal 57a. For this reason, it is hard to touch the 2nd terminal 57a of an energized state, and safety can be improved.

  In addition, when the cleaner body 1 is separated from the charging stand 5, the third protrusions 18 and the fourth protrusions 19 provided on the bottom surface 1 a of the cleaner body 1 can be used as legs. The stability of installation in the separated state is increased and the usability is improved.
