Compact tool combining vacuum/blower, pencil sharpener, rubbery eraser, and storage space

Abstract

A handheld device of compact size combining a mini electric vacuum/blower, a pencil sharpener, a rubbery eraser, and a storage unit. The inventive device has one or more containers that house a motor and rotary fan for the vacuum/blower, a battery that powers the vacuum/blower, a pencil sharpener, a rubbery eraser, and a storage unit. The vacuum is used to clean the crumbs from the rubbery eraser or other small objects on a surface, and the vacuum easily converts to a blower that will generate air steam. The storage unit can house certain sized school supplies such as crayons, pens, pencils, or other small items. The inventive of the device is compact enough so that it can be operated single handedly and it can be carried in pockets or small bags.

Claims

1. A handheld apparatus comprising: a housing having an outer wall of a cylindrical shape with a longitudinal axis, wherein the housing is configured to be carried by a user in a pocket or a bag, and a plurality of containers accommodated within the housing, wherein at least one of a pencil sharpener, a rubbery eraser, and a writing utensil is disposed in at least one of the plurality of containers, and at least one removable cap that covers at least one of a first end of the housing and a second end of the housing; wherein the handheld apparatus comprises a vacuum and a blower positioned in one of the plurality of containers, and wherein the vacuum and the blower comprise a hose coupled to the housing and configured to fold or retract to fit inside the housing without having to be disconnected from the housing to allow the at least one removable cap to close; wherein air is pushed out of the hose by the blower and is sucked in through the hose by the vacuum.

2. The handheld apparatus of claim 1, wherein each of the plurality of containers is shaped such that the plurality of containers fit together to correspond to the substantially cylindrical shape of the housing when accommodated inside the housing.

3. The handheld apparatus of claim 1, wherein the at least one removable cap comprises a first removable cap and a second removable cap, wherein the first removable cap covers at least the first end of the housing perpendicular to the longitudinal axis and the second removable cap covers at least the second end of the housing opposite the first end.

4. The handheld apparatus of claim 1, wherein the vacuum and the blower comprise a battery accommodated in one of the plurality of containers.

5. The handheld apparatus of claim 4, wherein the battery is selected from a rechargeable battery and a non-rechargeable battery.

6. The handheld apparatus of claim 1, wherein the vacuum and the blower comprise a motor and a fan housed in one of the plurality of containers, wherein said container has a removable cap for ease of emptying objects collected via the vacuum.

7. The handheld apparatus of claim 1, wherein the plurality of containers comprise a storage container configured to store at least one item, wherein the storage container has a removable screw-on cap.

8. The handheld apparatus of claim 1, wherein the housing and the plurality of containers are printed with a 3D printer.

DETAILED DESCRIPTION OF THE INVENTION

(6) Turning now descriptively to the drawings:

(7) FIG. 1 illustrates an operational view when the inventive device is used to vacuum or blow small objects 2 such as crumbs from the rubbery eraser 9. The air stream flows through the hose 3 that can be folded at the joint 4. The switch 1 can shift the rotary fan 13 between sucking in air and pushing air through the hose 3 into a compressed air stream. FIG. 1 also shows an internal view of the container that houses the battery 10 and rubbery eraser 9, and an additional container that functions as a storage space for school suppliers such as pencils 7 or crayons 6.

(8) FIG. 2A illustrates the side view of the container that houses the pencil sharpener 11, the motor 12 and the rotary fan 13. When the apparatus is not in use, caps 8a and 8b inserted at both ends of the device can be closed to safely house the internal components.

(9) FIG. 2B illustrates the side view of the container that houses the battery 10 and rubbery eraser 9. The battery 10 can be either rechargeable or non-rechargeable. The curved side of the container can be opened when the battery 10 is to be removed or recharged. The wires that connect the battery 10 to the motor 12 and switch 1 are not shown here.

(10) FIG. 2C illustrates the side view of the container that functions as a storage unit that a user can place small items into such as short pencils 7 or crayons 6. These items can be retrieved by opening either cap 8a or cap 8b from one end.

(11) FIG. 3 illustrates the cylinder shape 14 of the internal containers and how each container fits well with one another.

(12) In use, when the cap 8a is opened from one end, the user will see the vacuum/blower hose attached to a screw-on cap 5, the switch 1 to turn on/off the vacuum/blower, and the closed bottom of the storage container, as shown in FIG. 1.

(13) When the cap 8b is opened from the other end, the user will see the pencil sharpener 11 fixed to the inner sider of the container, a chamber for the rubbery eraser 9, and screw-on cap (not shown) of the storage unit.

(14) With respect to the above descriptions, they may contain certain specificities. However, it is to be realized that they should not be construed as limiting the scope of embodiments, but as merely providing illustrations of the principle of the invention. The optimum construction of the invention may include variation in size, material, shape, assembly, function and manner of operation whichever are deemed obvious to one skilled in art.

(15) Since numerous modifications and changes will readily occur to those skilled in art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly the scope of the embodiments should be determined by the claims in this application and their legal equivalent, rather than by the examples shown above.
