Abstract

A backpack dust collector includes a housing. The housing includes: a suction port; a dust collecting chamber connected to the suction port and configured to accommodate a dust collecting bag; a motor chamber connected to the dust collecting chamber and accommodating a fan and a motor; an exhaust port through which air from the motor chamber is discharged; first and second battery openings; and first and second battery receiving portions respectively corresponding to the first and second battery openings. At least part of the first battery opening is formed on a left side surface of the housing, and at least part of the second battery opening is formed on a right side surface of the housing.

First claim

What is claimed is:

1. A backpack dust collector comprising
a housing that includes:
a suction port;
a dust collecting chamber connected to the suction port and configured to accommodate a dust collecting bag;
a motor chamber connected to the dust collecting chamber and accommodating a fan and a motor;
an exhaust port configured such that air from the motor chamber is discharged through the exhaust port;
first and second battery openings configured such that a battery can be inserted into and removed from the housing through each of the first and second battery openings, and
a first battery receiving portion corresponding to the first battery opening and a second battery receiving portion corresponding to the second battery opening, each of the first and second battery receiving portions being configured to receive and retain the battery, wherein

at least part of the first battery opening is formed on a left side surface of the housing, and at least part of the second battery opening is formed on a right side surface of the housing,
the left side surface and the right side surface are opposite surfaces,
the each of the first and second battery receiving portions includes a guide rail configured to guide the battery as the battery is inserted into the each of the first and second battery receiving portions,
the guide rail extends in a right-and-left direction, and
the guide rail is inclined downward from the first battery opening or the second battery opening.

2. The backpack dust collector according to claim 1 , wherein the first battery opening is on the left side surface of the housing, and the second battery opening is on the right side surface of the housing.

3. The backpack dust collector according to claim 1 , wherein
the housing further comprising bottom plates that define bottom surfaces of the each of the first and second battery receiving portions,
each of the bottom surfaces is configured to face a part of a lower surface of the battery when the battery is received and retained by the each of the first and second battery receiving portions, and
the each of the bottom surfaces is inclined downward from the first battery opening or the second battery opening.

4. The backpack dust collector according to claim 1 , wherein
the first battery receiving portion includes a first battery mounting portion and the second battery receiving portion includes a second battery mounting portion, and
each of the first and second battery mounting portion is on an upper surface of the first battery receiving portion or the second battery receiving portion.

5. The backpack dust collector according to claim 4 , wherein the first battery opening and the second battery opening are at a lower portion of the housing.

6. The backpack dust collector according to claim 5 , wherein
the housing includes a front housing and a rear housing,
each of the front housing and the rear housing includes a bottom plate that defines a bottom surface of the each of the first and second battery receiving portions,
the bottom surface is configured to face a part of the lower surface of the battery when the battery is received and retained by the each of the first and second battery receiving portions, and
an opening is in the housing between the bottom plate of the front housing and the bottom plate of the rear housing.

7. The backpack dust collector according to claim 2 , wherein a dimension of the each of the first and second battery openings in a front-and-rear direction is larger than a dimension of the the each of the first and second battery receiving portions in the front-and-rear direction.

8. The backpack dust collector according to claim 7 , wherein
the housing includes a front housing and a rear housing,
each of the front housing and the rear housing includes inner side plates that define inner side surfaces connected to the first and second battery openings,
each of the inner side surfaces of the front housing is inclined rearward from the first battery opening or the second battery opening, and
each of the inner side surfaces of the rear housing is inclined forward from the first battery opening or the second battery opening.

9. The backpack dust collector according to claim 8 , wherein, in the each of the first and second the battery receiving portions, the battery is guided by the inner side surfaces and by and the guide rail.

10. The backpack dust collector according to claim 1 , wherein part of the first battery opening and part of the second battery opening are in a front surface of the housing.

11. The backpack dust collector according to claim 10 , wherein an inclination angle of the guide rail with respect to a lateral axis is equal to or smaller than 45 degrees.

12. The backpack dust collector according to claim 1 , further comprising a moving mechanism in the each of the first and second battery receiving portions and configured to generate force for moving the battery toward the first battery opening or the second battery opening.

13. The backpack dust collector according to claim 12 , wherein the moving mechanism is at a position where the moving mechanism is able to contact the battery.

14. The backpack dust collector according to claim 13 , wherein the moving mechanism includes an elastic member.

15. The backpack dust collector according to claim 1 , wherein the each of the first and second battery receiving portions is configured to receive a battery for a power tool.

16. A backpack dust collector comprising
a housing that includes:
a suction port;
a dust collecting chamber connected to the suction port and configured to accommodate a dust collecting bag;
a motor chamber connected to the dust collecting chamber and accommodating a fan and a motor;
an exhaust port configured such that air from the motor chamber is discharged through the exhaust port;
first and second battery openings configured such that a battery can be inserted into and removed from the housing through each of the first and second battery openings;
a first battery receiving portion corresponding to the first battery opening and a second battery receiving portion corresponding to the second battery opening, each of the first and second battery receiving portions being configured to receive and retain the battery; and
a first battery mounting portion in the first battery receiving portion and a second battery mounting portion in the second battery receiving portion, wherein

at least part of the first battery opening is formed on a left side surface of the housing, and at least part of the second battery opening is formed on a right side surface of the housing,
the left side surface and the right side surface are opposite surfaces,
the first battery mounting portion is on an upper surface of the first battery receiving portion and the second battery mounting portion is on an upper surface of the second battery receiving portion,
