Handy-type vacuum cleaner

1. A handy-type vacuum cleaner, comprising:

a vacuum cleaner main body;

a gripping part for use for gripping the vacuum cleaner main body; and

a blower attachment to be attached to/detached from the vacuum cleaner main body, wherein

the vacuum cleaner main body includes

an electric blower;

a dust-collecting part which can be attached to/detached from the vacuum cleaner main body and stores dust and dirt sucked by driving of the electric blower;

a connecting port which the blower attachment is inserted into/extracted from;

a suction air path which communicates between the connecting port and a suction port of the dust-collecting part;

a communicating air path which communicates between a communicating port, which connects to an exhaust port of the dust-collecting part, and a suction side of the electric blower;

an exhaust air path which communicates with an exhaust side of the electric blower and also communicates with the blower attachment when the blower attachment is inserted into the connecting port; and

a main body exhaust port which communicates with the exhaust air path,

while in a state where the blower attachment is inserted to the connecting port and the dust-collecting part is detached from the vacuum cleaner main body exposing the communicating port, outside air having been sucked into the vacuum cleaner main body at the communicating port and then passing via the communicating air path into the electric blower is discharged from the exhaust air path through the blower attachment, and

while in a state where the blower attachment is not inserted to the connecting port and the dust-collecting part is attached to the vacuum cleaner main body, the suction air path is connected to the communicating air path via the dust-collecting part and air having been sucked from the connecting port flowing through the suction air path, the dust-collecting part, and the communicating air path into the electric blower is discharged from the main body exhaust port.

2. The handy-type vacuum cleaner according to claim 1 , wherein

the exhaust air path is disposed on a line extending in an insertion direction of the blower attachment to be inserted into the connecting port, and

the vacuum cleaner main body includes an opening/closing valve which is disposed on the line extending in the insertion direction of the blower attachment to be inserted into the connecting port, and which is operated by insertion/extraction of the blower attachment with respect to the connecting port so as to open and close connection between the exhaust air path and the blower attachment.

3. The handy-type vacuum cleaner according to claim 2 , further comprising:

suction tools, at least one of which is selectively inserted into/extracted from and connected to the connecting port instead of the blower attachment, and a downstream side of which is located in an upstream side to the opening/closing valve when inserted into the connecting port.

4. The handy-type vacuum cleaner according to claim 2 , wherein the vacuum cleaner main body further includes a biaser which biases the opening/closing valve toward an opposite direction to the insertion direction of the blower attachment to be inserted into the connecting port.

5. The handy-type vacuum cleaner according to claim 1 , wherein the vacuum cleaner main body further includes:

a first opening which is provided on the suction air path, communicates between the suction air path and the suction port of the dust-collecting part, and is closed by the blower attachment inserted into the connecting port; and

a second opening which communicates between the exhaust port of the attached dust-collecting part and the communicating air path and is exposed outside of the vacuum cleaner main body when the dust-collecting part is detached.

6. The handy-type vacuum cleaner according to claim 5 , wherein the dust-collecting part includes an obstructing part which obstructs connection of the blower attachment to the connecting port when the dust-collecting part is attached to the vacuum cleaner main body.

7. The handy-type vacuum cleaner according to claim 1 , wherein the blower attachment includes:

an exhausting section which communicates with the exhaust air path when the blower attachment is connected to the connecting port; and

a communicating section which communicates with the suction air path when the blower attachment is connected to the connecting port.

8. The handy-type vacuum cleaner according to claim 1 , comprising:

a suction attachment to connect to the connecting port, wherein

the blower attachment has an external shape so that, when a downstream side of the blower attachment is inserted into and connected to the connecting port, an upstream side of the blower attachment is inserted into and fitted to the suction attachment connected to the connecting port.

9. The handy-type vacuum cleaner according to claim 1 , further comprising

a battery which supplies power to the electric blower.

10. The handy-type vacuum cleaner of claim 1 , wherein the vacuum cleaner main body further includes a suction communicating port to connect with the suction port of the dust-collecting part when the dust-collecting part is attached to the vacuum cleaner main body, the suction communicating port being different from the connecting port of the vacuum cleaner main body.
