It may be an LED lamp indicating that the dust sensor detects dust.

4). Weight balance In FIG. 4, the components of the main body 2 of the hand-held vacuum cleaner 1 are shown in a simplified manner.

  There is a nozzle 3 in the opening 20 at the front of the main body 2, and along the longitudinal direction A of the main body 2, the dust collecting section 4, the rotary fan 65 of the electric blower 64, the motor 62, and the through hole 54 are directed rearward. It is arranged linearly.

  The main body 2 has the grip portion 5 above the through hole 54, and the battery pack 8 is disposed below the through hole 54.

  The through hole 54 extends from the fourth position P4 to the fifth position P5 along the longitudinal direction A. Since the through hole 54 forms the grip portion 5 together with the upper surface 27 of the main body 2, the grip portion 5 also extends from the fourth position P 4 to the fifth position P 5 along the longitudinal direction A above the through hole 54. The grip portion 5 and the through hole 54 have a length L3 in the longitudinal direction A.

  The battery pack 8 extends from the first position P1 located in front of the grip portion 5 along the longitudinal direction A to the second position P2 behind the grip portion 5. The second position P2 can also serve as the rear end of the main body 2. The battery pack 8 has a length L4 that is longer than the length L3 of the grip portion 5 in the longitudinal direction A.

  More specifically, the battery pack 8 is formed longer than the length L3 of the grip portion 5 by a length L1 along the longitudinal direction A to the lower side of the motor 62 in front of the through hole 54. Further, the battery pack 8 is formed to be longer rearward by a length L2 along the longitudinal direction A behind the through hole 54. Therefore, the length L4 in the longitudinal direction A of the battery pack 8 is longer than the length L3 of the grip portion 5 by the lengths L1 and L2.

  The length L1 and the length L2 can be substantially the same length. For example, when the total length L4 of the battery pack 8 is 100%, the lengths L1 and L2 are in the range of 20% to 30%. Can be set as appropriate. In the present embodiment, the length L1 is set to 25% and the length L2 is set to 28%, and the rear side of the battery pack 8 is slightly longer. This is to slightly adjust the weight balance biased forward by the electric blower 64 in front of the grip portion 5.

  Thus, the battery pack 8 extends over the front and rear of the gripping portion 5, so that the weight of the battery pack 8 is distributed in a well-balanced manner to the entire gripping portion 5, thereby further improving the user-friendliness. be able to. More specifically, the battery pack 8, which is the heaviest part in the main body 2, is disposed below the gripping portion 5 and longer than the gripping portion 5. Improves stability.

  The center of gravity G of the hand-held vacuum cleaner 1 can be closer to the electric blower 64 than the grip portion 5. Since the center of gravity G is on the electric blower 64 side with respect to the grip portion 5, the opening 20 side, which is the most common use state in the use state, tends to be inclined downward. Therefore, it is easy to apply the load of the main body 2 to the finger hung on the finger hanging portion 52, and the user's ease of holding can be further improved. Even when the nozzle 3 is not attached, the center of gravity of the main body 2 is on the electric blower 64 side in front of the grip portion 5.

  4 shows how the battery pack 8 effectively uses the space in the main body 2. In general, a relatively wide space exists below the motor. However, in the main body 2 of the present embodiment, the front portion of the battery pack 8 is disposed in the space below the motor 62, and the main body 2 is reduced in size. doing.

  The main body 2 of the handheld vacuum cleaner 1 has an elongated appearance along the longitudinal direction A from the opening 20.

  As shown in FIGS. 4 and 5, in the main body 2, the position having the thickest outer dimensions D <b> 1 and D <b> 2 in the direction orthogonal to the longitudinal direction A is the position of the electric blower 64, particularly the position of the rotary fan 65. .
