In the state of FIG. 11, when the hand switch 15 of the handle body 14 of the grip portion 3 is appropriately operated, a control signal is transmitted from the grip portion 3 to the suction port body 20 by wire, and in response to this, the suction port body is received. The blower motor 47 of 20 is driven by a DC power source, the blower 46 sucks air (blows to the discharge side), the rotary brush motor 49 of the suction body 20 is driven by a DC power source, and the rotary brush 48 is positioned above the suction opening 44. Rotate on. When the blower 46 operates, the check valve 52 disposed in the air outlet flow path discharged from the blower 46 is opened by the air flow sent out by the blower 46. As a result, the suction brush 4 is wound up by the rotating brush 48 and the suction port opening 4
The dust sucked from 4 is sent to the dust collecting portion of the suction port main body 20. The air sent to the dust collecting portion of the suction body 20 is sent to the air passage 77 in the suction body via the filter 53, the air outlet flow path in which the check valve 52 is opened, and the outlet hole 78. It is dispersed and discharged obliquely upward to the outside air through a large number of obliquely upward discharge small holes formed in the rear case 76. Further, a part of the air flow is sent from the suction port inner air passage 77 to the installation chamber 79 of the brush motor 49 via the inlet hole 80, and after cooling the brush motor 49 and the circuit board 51. The gas is discharged obliquely upward from the discharge hole 81 of the arrangement chamber 79 to the outside air side.

As described above, in this embodiment, the control unit switches the control mode depending on whether or not the handle body 2 is attached to the grip portion 3, so that the grip body 3 is used depending on whether or not the handle body 2 is attached. The user does not need to change the operation mode, which is user-friendly and easy to use. Further, when the stick type assembly including the grip portion 3, the extension pipe portion 4 and the suction body portion 5 is used as an independent vacuum cleaner, the exhaust gas is dispersed and discharged obliquely upward, so that the exhaust noise is small, In addition, there is no risk of dust being rolled up by the exhaust gas, which is also user-friendly in this respect. Further, since the brush motor 49 and the circuit board 51 are cooled by a part of the exhaust gas, the reliability of the life of the circuit elements can be improved.

The grip portion 3 shown in FIG.
Is connected, the switching valve 86 is always set to the first state described above. At this time, since the circulation hole 85 is closed, the circulation brush 85 is closed through the circulation hole 85. Exhaust gas does not flow into, and the same operation as described in FIG. 10 is performed.

On the other hand, when the hose portion 2 is not connected to the grip portion 3 shown in FIG. 13, the switching valve 86 is adapted to select either the first state or the second state. , When the switching valve 86 is in the first state,
The same operation as described in 1 is performed. On the other hand, the switching valve 86
In the second state, the circulation hole 85 is opened and the discharge hole 81 is closed, so that the exhaust gas sent to the installation chamber 79 of the brush motor 49 is rotated through the circulation hole 85. It is sent to the brush arrangement chamber and a so-called exhaust circulation type cleaning operation is performed.

As described above, in the first modification of the present embodiment, when the stick type assembly including the grip portion 3, the extension tube portion 4 and the suction body portion 5 is used as an independent vacuum cleaner, Since an exhaust circulation type cleaning operation can be selected, it is possible to increase the dust winding power by exhaust circulation.

FIG. 14 shows a second modification of this embodiment, which is an exploded perspective view of the mouthpiece main body 20 of the mouthpiece body 5. This example differs from the configurations of FIGS. 10 and 11 in that the rear case 76 and the outlet hole 78 are removed, and instead,
An exhaust dispersion case 90 is provided above the upper case 42, and a plurality of exhaust outlets 42a are provided in the upper case 42 where the blower 46 is provided. In the present example, the exhaust gas sent out from the air outlet flow path in which the check valve 52 is opened flows into the air passage in the suction body formed between the upper case 42 and the exhaust gas dispersion case 90. From the exhaust small holes 90a provided in the exhaust dispersion case 90, the particles are dispersed upward and discharged to the outside air side. Also in the second modified example having such a configuration, when the stick type assembly including the grip part 3, the extension tube part 4 and the suction body part 5 is used as an independent vacuum cleaner, an exhaust sound is generated. It can be made small, and there is no risk of dust being taken up by exhaust air.
