(Embodiment 1)
Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings. In FIGS. 1 and 2, reference numeral 21 denotes a main body, which has an electric blower chamber 23 having a built-in electric blower 22 at the rear and a dust collection chamber 25 having a filter paper body 24 at the front, and a front thereof. And a suction port 27 holding a shelf nozzle 26. Reference numeral 28 denotes a switch for controlling the operation of the rechargeable vacuum cleaner, which is held at an upper portion of the main body 21, and a handle 29 is formed behind the switch. Reference numeral 30 denotes a battery, which is attached to the main body 21 by holding claws (not shown) behind the rear handle of the main body. Reference numeral 31 denotes a battery contact point which is engaged with a contact plate 32 which is held in the handle by the body 21 and electrically connected to the battery. Reference numeral 33 denotes a space provided at the bottom of the main body, which is formed by providing a box-shaped concave portion of the electric blower room 23 and the battery holding portion 34 with the main body wall 35. 36 is a dust nozzle, and 37 is a gap nozzle.

The dust nozzle 36 and the gap nozzle 37 are held in a space 33 provided at the bottom of the main body so as to be vertically overlapped. By holding the gap nozzle 37, which is frequently used and large in shape, below, there is no danger that the dust nozzle 36 will be insufficiently fixed and will fall out of the main body even if it comes off the holding rib 38, In addition, there is an effect that it does not become an obstacle even when the frequently used gap nozzle 37 is removed.

(3) The dust nozzle 36 includes a body 39 that is engaged with and held by the tip of the gap nozzle 37 and a tube 40 that is formed in communication therewith, as shown in FIG. Thus, chips and the like generated when drilling holes can be sucked in and used for construction work, so that the range of use of the rechargeable vacuum cleaner is expanded.

、 FIGS. 4 and 5 show a body and a tube which are divided and exchangeable, and are composed of a body 41 and a tube 42 which engage with the gap nozzle 37. Since the tube 42 is held by press-fitting, it can be removed, and as shown in FIG. 5, can be replaced with a long tube 43 having a shape, a tube 44 having flexibility, and the like.

As described in the main body configuration, the rechargeable vacuum cleaner according to the present invention has a heavy battery 30 exposed to the rear of the main body as shown in FIG. Can be located. For this reason, when the front of the handle 29 is held from the center of gravity G, the center of gravity G is located behind the hand, and the air inlet 27 of the main body of the rechargeable cleaner becomes easy to face upward. Next, when the user has a position behind the center of gravity G, the intake port 27 is easily directed downward, so that the direction of the intake port can be changed depending on where the handle 29 is held.

(7) As shown in FIG. 7, by providing a convex portion 45 on the lower surface of the handle 29 and below the center of gravity G2, the direction of the air inlet of the rechargeable vacuum cleaner can be more easily adjusted.

Next, as shown in FIG. 8, in this rechargeable vacuum cleaner, the battery 30 is attached to the handle 29 at the rear of the main body at an angle. Therefore, when the main body is turned upside down with the battery 30 as the bottom surface, the main body of gravity g2 is located away from the center line 46 of the battery 30, so that the main body tilts toward the center of gravity and falls. However, when the battery 30 is removed and inverted, the center of gravity g2 exists near the center line 49 between the battery holding upper part 47 and the lower part 48 of the main body as shown in FIG. Because of the presence between them, the balance is good and fall can be prevented.

Therefore, when the battery is charged, the main body can be held in an inverted state, so that the storage capacity is improved and the battery 30 is not held. effective.

Also, as shown in FIG. 10, by attaching the suspending band 50 in front of the rear battery 30 of the main body, the center of gravity G3 exists near the front of the band 50. The surface 51 and the floor surface 52 become parallel, so that cleaning can be performed without holding the handle 29.

As described above, the rechargeable vacuum cleaner according to the present invention can change the direction of the air inlet depending on the location where the handle is held, and is particularly useful for reducing the burden on the wrist during transportation or use.
