Abstract

A dust collecting device includes a tank and a main body housing a motor and detachably attachable to an upper part of the tank. A handle and a cover are both provided in an upper part of the main body. The handle is capable of being raised and turned down around a handle rotation shaft. The cover is capable of being opened and closed around a cover rotation shaft and covers a housing portion provided in the main body in a closed position. The cover rotation shaft is provided in parallel to the handle rotation shaft. The cover rotation shaft is positioned closer to a grip portion of the handle than the handle rotation shaft so as to overlap with a part of the handle. The handle rotation shaft is positioned closer to the cover than the cover rotation shaft so as to overlap with a part of cover.

Claims

1. A dust collecting device comprising:

a tank; and

a main body housing a motor and detachably attached to an upper part of the tank,

wherein a handle which is capable of being raised and turned down around a handle rotation shaft and a cover which is capable of being opened and closed around a cover rotation shaft and which covers a housing portion provided in the main body in a closed position are provided in an upper part of the main body,

the cover rotation shaft is provided in parallel to the handle rotation shaft, the cover rotation shaft being positioned closer to a grip portion of the handle than the handle rotation shaft so as to overlap with a part of the handle, and the handle rotation shaft being positioned closer to an end of the cover than the cover rotation shaft so as to overlap with a part of the cover, and

the cover includes an upper plate portion that overlaps the handle rotation shaft in a closed position of the cover such that the cover is above and covers the handle rotation shaft.

2. The dust collecting device according to claim 1,

wherein the housing portion is provided with a battery connection portion for connecting a battery.

3. The dust collecting device according to claim 1,

wherein a switch for activating the motor is arranged in a front part of the main body, the handle is arranged in a rear side of the switch and the cover is arranged in a rear side of the handle respectively.

4. The dust collecting device according to claim 1,

wherein a clearance recessed portion facing the handle in a turned-down state is formed on an upper surface of the main body.

5. The dust collecting device according to claim 1,

wherein a pipe support portion configured to support a pipe is provided in the main body, and

the cover has a shape not interfering with the pipe supported by the pipe support portion at the time of opening and closing.

6. The dust collecting device according to claim 1,

wherein the cover is provided with a hook elastically locked to the main body in a closed position of the housing portion.

7. The dust collecting device according to claim 1,

wherein a detachably attached housing box is provided in the main body.

8. The dust collecting device according to claim 7,

wherein, in a closed position of the housing portion, the cover restricts movement of the housing box in a direction of removing the housing box.

9. The dust collecting device according to claim 8,

wherein the housing box is attached to the main body by inserting fitting protrusions protruding on an outer surface into coupling portions provided in the main body from above, and

the cover is provided so as to rotate in an up and down direction to close the housing portion provided above the coupling portions from above.

10. The dust collecting device according to claim 7,

wherein the housing box has a pocket shape an upper part of which is opened, and partition plates are provided thereinside.

11. The dust collecting device according to claim 7,

wherein a suction opening is arranged in a front part of the main body, and

the housing box is arranged in a rear part of the main body.

12. The dust collecting device according to claim 7,

wherein the housing portion is provided with a battery connection portion for connecting a battery, and

the battery is capable of being housed in the housing box.

13. A dust collecting device comprising:

a tank; and

a main body housing a motor and detachably attached to an upper part of the tank,

wherein a handle which is capable of being raised and turned down around a handle rotation shaft and a cover which is capable of being opened and closed around a cover rotation shaft and which covers a housing portion provided in the main body in a closed position are provided in an upper part of the main body,

the cover rotation shaft is provided in parallel to the handle rotation shaft, the cover rotation shaft being positioned closer to a grip portion of the handle than the handle rotation shaft so as to overlap with a part of the handle, and the handle rotation shaft being positioned closer to an end of the cover than the cover rotation shaft as to overlap with a part of the cover,

a cord is connectable to the main body,

the main body is provided with a fall-off stopper portion stopping fall-off of the connected cord from the main body, and

the cover covers a cord connection portion to which the cord is connected, and has the fall-off stopper portion.

14. The dust collecting device according to claim 13,

wherein a battery connection portion to which a battery is connectable is provided in the main body, and

the cover covers both the cord connection portion and the battery connection portion.

15. The dust collecting device according to claim 13,

wherein ribs positioned inside the cover are provided at right and left of the cord in the cord connection portion.

16. A dust collecting device comprising:

a tank; and

a main body housing a motor and detachably attached to an upper part of the tank,

wherein a handle which is capable of being raised and turned down around a handle rotation shaft and a cover which is capable of being opened and closed around a cover rotation shaft and which covers a housing portion provided in the main body in a closed position are provided in an upper part of the main body,
