Description

Technical Field

[0001] This utility model relates to a paper shredder, and more particularly to a paper shredder with a projection function. Background Technology

[0002] Existing paper shredders, such as those with digital displays or LED indicator lights, only display digital information on the shredder's status, such as overheating, full paper, sleep mode, forward rotation, and reverse rotation. They have no other use. For safety reasons, paper shredders need to have safety warning signs affixed to prominent locations such as the top or front surface. However, over time, these signs may fall off or become blurred, thus failing to provide effective warnings. Utility Model Content

[0003] The purpose of this utility model is to provide a paper shredder with projection function. The technical problem to be solved is to enable the paper shredder to have projection function and improve the user experience.

[0004] To solve the above problems, this utility model provides a paper shredder with projection function, including a paper shredder body, on which a micro projector is provided. The micro projector is electrically connected to a control board inside the paper shredder body to display information about the paper shredder.

[0005] Furthermore, the lens of the micro projector is facing downwards.

[0006] Furthermore, the shredder body is provided with a micro projector assembly area, including a stepped surface with a through hole. The lens of the micro projector is opposite to the through hole, and the micro projector is fixed on the stepped surface by a bracket.

[0007] Furthermore, the micro projector assembly area is located at the front end or one side of the shredder body.

[0008] Furthermore, the bracket includes a receiving cavity for accommodating a micro projector, the receiving cavity having an opening opposite to a through hole. The bracket also includes symmetrically arranged stud sleeves, with studs adapted to the stud sleeves on the stepped surface. The studs have threaded holes, and the bracket is threadedly fastened to the studs by screws passing through the holes on the stud sleeves and threaded into the threaded holes on the studs.

[0009] Furthermore, the step surface is provided with a protrusion with an inclined surface, and the protrusion is provided with an inclined groove. A through hole is provided at the position of the protrusion and passes through the groove. One end of the micro projector lens is placed in the groove so that the micro projector is tilted and the image it projects is formed on the ground in front of the paper shredder.

[0010] Furthermore, the micro projector assembly area is located close to the inner wall of the shredder body.

[0011] Furthermore, a wedge is provided between the support and the inner wall of the shredder body.

[0012] Compared with the prior art, this utility model sets up a micro projector in the main body of the paper shredder to project safety warning signs and paper shredder status information. Since the projection direction is towards the ground, the safety warning signs and paper shredder status information can be more easily viewed when in use, realizing visual interaction and improving the user experience. Moreover, there is no need to paste safety warning signs on the paper shredder, which can reduce the amount of stickers used and make the outer surface of the paper shredder cleaner.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0018] In this utility model, the main mechanisms of the paper shredder, such as the power system, cutting device, and transmission mechanism, have not been modified. The improvement lies in the addition of a projection part mechanism.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a paper shredder with projection function, including a paper shredder body 4, an integrally connected base 1 at the lower end of the paper shredder body 4, a removable trash can (not shown in the figure) on the base 1, a micro projector 3 on the paper shredder body 4, the micro projector 3 being electrically connected to a control board (not shown in the figure) inside the paper shredder body 4, the lens of the micro projector 3 facing downwards, so as to project warning information and / or paper shredder status information onto the ground after the trash can of the paper shredder is removed, the control board having a main controller, and the micro projector 3 being controlled by the main controller (the main controller and control board are prior art and will not be described in detail here).

[0020] like Figure 1 , Figure 2 and Figure 3As shown in this utility model, a micro projector assembly area is provided at the front end of the shredder body 4. This front end is the end where the operator faces the shredder. The micro projector assembly area includes a stepped surface 5, and a through hole 6 is provided on the stepped surface 5. The lens of the micro projector 3 is opposite to the through hole 6. The micro projector 3 is fixed on the stepped surface 5 by the bracket 2. By keeping the micro projector 3 away from the power system, cutting device and transmission mechanism of the shredder, the vibration of the shredder is prevented from interfering with the operation of the micro projector 3. This interference can cause the image of the micro projector 3 to shake.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the bracket 2 includes a receiving cavity 7 for accommodating the micro projector 3. The receiving cavity 7 has an opening and is adapted to the external shape of the micro projector 3. The opening is opposite to the through hole 6. The bracket 2 also includes symmetrically arranged stud sleeves 8. A stud 9 adapted to the stud sleeve 8 is provided on the stepped surface 5. The stud 9 is provided with a screw hole. The bracket 2 is threadedly fastened to the stud 9 by screws passing through the holes on the stud sleeves 8. The stud sleeves 8 are symmetrically arranged on both sides of the bracket 2.

[0022] To prevent the mini projector 3 from projecting onto the ground too close to the projector, such as... Figure 3 As shown, a raised portion 10 with an inclined surface is provided on the stepped surface 5. A groove 11 with an inclined surface is provided on the raised portion 10. The bottom surface of the groove 11 is inclined, specifically, the height decreases sequentially from the front end to the rear end of the projector body 4. A through hole 6 is provided at the position of the raised portion 10 and passes through the groove 11. One end of the lens of the micro projector 3 is placed in the groove 11 so that the micro projector 3 is tilted and the image it projects is formed on the ground at the front end of the paper shredder. In order to make the size of the image projected by the micro projector 3 adjustable, the through hole 6 is a trapezoidal round hole, which is radially arranged towards the outside of the paper shredder body 4.

[0023] like Figure 2 As shown, the micro-projection assembly area is located near the front inner wall of the shredder body 4. A wedge 12 is provided on the bracket 2. The wedge 12 is triangular and is tightly pressed against the front inner wall of the shredder body 4 to prevent mechanical vibration during shredder operation from affecting the projection stability.

[0024] like Figure 3 As shown, in order to avoid the shredder body from obstructing the micro projector 3, an avoidance groove 13 is provided at the front end of the shredder body 4 at the position of the through hole 6.

[0025] In the prior art, a heavy-duty switch 14 is provided in the main body 4 of the paper shredder. The heavy-duty switch 14 is connected to the main controller and is located at the top of the space where the waste bin is housed in the base 1. When the heavy-duty switch 14 is turned on, the main controller controls the micro projector 3 to work.

[0026] When the trash can is closed, it contacts the hard-touch switch 14, which is in the open state. At this time, the main controller does not control the micro projector 3 to work.

[0027] When the trash can is pulled out, it does not contact the re-touch switch 14. At this time, the re-touch switch 14 is turned on. After receiving the signal from the re-touch switch 14, the main controller controls the micro projector to work and project the information onto the ground. Figure 4 (As shown).

[0028] This utility model integrates a projection function into the paper shredder, eliminating the need to print relevant information (warning messages, etc.) on the shredder casing. This enables visual interaction with the user. Since the projection is on the ground, it provides better guidance when the user is looking down to operate the shredder. Furthermore, the projector itself has adjustable screen size, so there is no need to worry about warning messages taking up too much space on the shredder surface, thus improving the user experience.
