Abstract

This invention relates to a paper shredder with automatic paper separator, including a housing, having a paper inlet and a paper outlet; a motor and a plurality of rotary shaft and cutting blades assembly contained within the housing; a paper separating wheel contained also within the housing; and a paper supporting tray disposed at the paper inlet of the housing; each of the two sidewalls of the housing is mounted with a supporting arm; the paper inlet of the housing is installed with a paper intake sensing device. Rather than being inspected by the user throughout the whole shredding process, papers can be destroyed automatically by using the paper supporting tray and the paper separating wheel disposed at the paper inlet of the housing; Moreover, the room is saved and the size of the shredder is reduced since the supporting arms mounted on the sidewalls of the housing may hold any dustbins and use them as wastebasket for the paper shredder.

Description

TECHNICAL FIELD

This invention relates generally to an office electrical appliance, and more particularly to a portable paper shredder with automatic paper separating device.

BACKGROUND

Paper Shredders are well known devices for destroying papers. In a typical configuration of the paper shredder of the prior art, paper to be destroyed have to be guided manually and continuously into the paper shredder which results in fairly complex operation and efficiency compromises. Furthermore, large scale paper shredders are often equipped with external wastebasket, and small scale paper shredders usually have built-in internal wastebasket, the large dimensions of the wastebasket has been a drawback as, on one hand, more space are needed to accommodate such wastebasket, and on the other hand, excessive efforts have to be paid to move such wastebasket.

DESCRIPTION

One aspect of the invention is to provide a paper shredders with automatic paper separating device to overcome the deficiencies e.g. complex operation and large volume that accompanied with the paper shredders of the prior art.
The technical solution of the invention is: a paper shredder with automatic paper separator, including a housing, having a paper inlet and a paper outlet; a motor and a plurality of rotary shaft and cutting blades assembly contained within the housing; a paper separating wheel contained also within the housing; and a paper supporting tray disposed at the paper inlet of the housing.
Preferably, each of the two sidewalls of the housing is mounted with a supporting arm.
Preferably, the paper inlet of the housing is installed with a paper intake sensing device.
The advantageous effects of this invention are as follows: rather than being inspected by the user throughout the whole shredding process, papers can be cut automatically by using the paper supporting tray and the paper separating wheel disposed at the paper inlet of the housing; Moreover, the room is saved and the size of the shredder is reduced since the supporting arms mounted on the sidewalls of the housing may hold any dustbins and use them as wastebasket for the paper shredder.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

One embodiment of the invention is shown by Figure 1 to 3, a paper shredder with automatic paper separator, including a housing 1 having a paper inlet 2 and a paper outlet 3 thereon, a motor 4 and a plurality of rotary shaft and cutting blades assembly 5 contained within the housing, a paper separating wheel 6 contained also within the housing, and a paper supporting tray 7 disposed at the paper inlet of the housing. Each of the two sidewalls of the housing is mounted with a supporting arm 8. The paper inlet 2 of the housing 1 is installed with paper intake sensing device.
Another embodiment of the invention is shown by Figure 4. This embodiment differs from the first one only in that the cutting blades on the rotary shaft are crossed.
When this invention is in use, a common dustbin 9, which is previously disposed below the paper shredder by means of the two supporting arms, will be used as the wastebasket of the paper shredder, and the paper to be shredded is disposed on the paper supporting tray 7; after turning on the switch 10, the paper on the supporting tray will be sensed by the sensing device; the paper-separating wheel 6 is driven and the paper to be shredded is carried into the housing 1, consequently, the paper is shredded by the rotary shaft and cutting blade assembly 5, and the destroyed paper drops into the predisposed dustbin.

Claims
