DETAILED DESCRIPTION

[0026] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be noted that, unless otherwise specified, "plurality" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be construed as limiting the present invention. In addition, the terms "first", "second", "third", etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0029] Reference Figures 1-8The schematic diagram of the structure of the intelligent pencil sharpener provided by the present invention includes a base 1, a protective cover 2 and an upper cover 3. The protective cover 2 is sleeved on the outer ring of the base 1, and the upper cover 3 is arranged on the top of the protective cover 2. A motor 4 and a cutting seat 5 are provided on the base 1. The motor 4 drives the cutting seat 5 to rotate. The top of the cutting seat 5 is rotatably connected to the upper cover 3. The cutting seat 5 is provided with a tapered hole 501 with a gradually decreasing diameter from the top to the bottom. The top of the upper cover 3 is provided with a socket 301 opposite to the tapered hole 501. The outer side of the cutting seat 5 is provided with a cutting surface 502, and the cutting surface 502 passes through the side wall of the tapered hole 501. The cutting surface 502 is divided into a left and a right surface. A blade fixing hole 6 is provided on either of the left and right surfaces of the cutting surface 502. A pencil cutting blade is fixed to the blade fixing hole 6 by screws, so that the cutting edge of the blade is aligned with the tapered hole 501 between the left and right surfaces of the cutting surface 502. When the cutting seat 5 rotates, the pencil is in a fixed state. At this time, the blade cuts the bottom of the pencil through the tapered hole 501 between the cutting surfaces 502. In this way, the pencil is cut. The above structure is a common existing technology. Therefore, the blade is removed to facilitate observation of the internal structure of the cutting seat 5.

[0030] See Figure 5-Figure 8 An adjusting hole 7 is provided on the bottom side wall of the tapered hole 501, and an adjusting block 8 is provided in the adjusting hole 7 for sliding left and right. A rotating shaft 10 is provided on the outer side of the cutting seat 5 behind the adjusting block 8. The front end of the rotating shaft 10 is threadedly connected with the adjusting block 8. When the rotating shaft 10 is rotated, the front end of the rotating shaft 10 and the adjusting block 8 threadedly rotate. Since the rotating shaft 10 can only rotate, and the adjusting block 8 can only slide left and right, the left and right sliding of the adjusting block 8 is controlled. The internal rotating shaft 10 can drive the adjusting block 8 to slide left and right in the adjusting hole 7, thereby adjusting the bottom diameter size of the tapered hole 501, so that it is suitable for pencils of different thicknesses, and the diameter size adjustment process is stepless adjustment, which is more intelligent than the gear adjustment and has a wider range of applications, thereby improving the intelligence level of the electric pencil sharpener.

[0031] See Figure 4 A rotating platform 11 is mounted on the base 1. A motor 4 drives the rotating platform 11, and a cutting seat 5 is attached to the rotating platform 11. As a key component of the pencil sharpener, the cutting seat 5 is separated and can be removed and replaced, improving interchangeability and utilization. The motor 4 drives the rotating platform 11 through a reduction gear set 12. The gear set's transmission ratio control provides more precise control, enabling more accurate coordination between speed and torque.

[0032] See Figure 1 and Figure 2The top cover 3 is connected to the protective cover 2 by a screw-on snap. The top of the top cover 3 is engraved with a rotary lock. Turn the clockwise rotation to open the top cover 3 and counterclockwise to lock the top cover 3 and protective cover 2. The protective cover 2 is transparent, allowing you to view the pencil's cutting progress. The protective cover 2 is connected to the base 1 with a snap-on snap, making it easy to install and remove, and very convenient for cleaning internal debris later.

[0033] See Figure 3 The base 1 is provided with a battery compartment 13 with a built-in rechargeable battery for easy carrying and trial. The bottom of the base 1 is provided with a rubber pad 14, which can increase friction when the pencil sharpener is placed on a table and improve the stability of the pencil sharpener during operation.

[0034] Working principle:

[0035] During use, the diameter of the pencil is determined, and the adjusting block 8 is driven to slide left and right in the adjusting hole 7 by the internal rotating shaft 10, thereby adjusting the bottom diameter of the tapered hole 501 to adapt it to the pencil to be cut. The pencil is then inserted from the insertion hole 301 on the top of the upper cover 3 into the tapered hole 501 on the cutting seat 5, and the motor 4 is started to cut the pencil.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
