Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pencil sharpener, in particular to a knife holder dust removal assembly and a pencil sharpener. BACKGROUND

[0002] In the existing pencil sharpener technology, the knife holder is generally provided with a pencil storage bin, a hob is installed on one side of the pencil storage bin for cutting pencils, and a pencil blocking block is usually installed below the pencil storage bin. The main function of the pencil blocking block is to control the feeding of the pencil to ensure the stability of the pencil during cutting. However, during the cutting of the pencil, some pencil dust will accumulate around the pencil blocking block. The accumulation of such dust will limit the movement of the pencil blocking block, thereby affecting its normal work.

[0003] Related prior art such as Chinese patent application "A delay pencil sharpening structure and an automatic pencil sharpener with the same", application number: CN202223397083.1; discloses a delay pencil sharpening structure, which includes: a pencil blocking block; a touch lever; an adjusting wheel abutting the lower end of the touch lever, and the adjusting wheel moves along the axial direction relative to the support table between a first position and a second position; a transmission lever assembly linked with the adjusting wheel, the upper end of the transmission lever assembly is provided with a second engagement part, and the second engagement part moves relative to the drive gear plate between a third position and a fourth position following the movement of the adjusting wheel. The second engagement part on the third position is simultaneously meshed and connected with the drive gear plate and the limiting turntable, and the second engagement part on the fourth position remains meshed and connected with one of the drive gear plate and the limiting turntable, and is disconnected with the other. The utility model provides a delay pencil sharpening structure, which utilizes the pencil feeding to drive the pencil blocking block to move downward, and the pencil blocking block drives the adjusting wheel to drive the transmission lever assembly to move through the touch lever, so as to disconnect the power between the knife holder assembly and the pencil feeding assembly.

[0004] Specifically, the pencil blocking block of the existing pencil sharpener is usually connected with a delay device. The function of the delay device is to control the knife holder assembly to continue cutting for a period of time after the pencil tip contour cutting is completed to polish the pencil tip surface smoothly. However, when the pencil dust accumulates at the pencil blocking block, the movement of the pencil blocking block will become inflexible, and it may even be stuck. This not only affects the normal movement of the pencil blocking block, but also may cause problems in the response of the delay device, thereby affecting the working efficiency and use experience of the entire pencil sharpener.

[0005] Therefore, it is necessary to solve the problem of accumulation of pencil ash in the pencil sharpener. Chinese patent application "A pencil sharpener and a pencil sharpener with the pencil sharpener", application number: CN202221994745.0, discloses a pencil sharpener comprising a frame body, the upper and lower ends of the frame body are provided with a pencil storage compartment and a cylindrical connecting part, the connecting part is connected with the connecting key, the connecting part has a ash removal structure, the ash removal structure is used for moving the pencil ash and / or wood chips below the connecting part to the outside. The ash removal structure comprises one or more chip removal parts which are formed by extending downward from the lower end of the connecting part.

[0006] The above-mentioned ash removal structure is formed by extending downward from the lower end of the connecting part of the pencil sharpener, which adds a chip removal structure to the pencil sharpener structure. However, as a passive chip removal structure, it is difficult to completely avoid the accumulation of ash, and it is not easy to remove the accumulated ash when the ash has accumulated. Therefore, the present application designs another pencil sharpener ash removal assembly which can effectively remove or reduce the accumulation of ash. Content of the utility model

[0007] The technical problem to be solved by the present application is to provide a pencil sharpener ash removal assembly and a pencil sharpener, which adds an ash removal gear structure, and drives the rotation of the ash removal gear by a power device to remove the ash below the pencil block, effectively avoiding the movement of the pencil block.

[0008] The technical scheme adopted by the present application is: a pencil sharpener ash removal assembly and a pencil sharpener, comprising a pencil sharpener, the pencil sharpener is provided with a pencil storage compartment, the lower part of the pencil storage compartment is provided with a pencil block, one side of the pencil block is provided with an ash removal gear, the ash removal gear partially extends below the pencil block, the ash removal gear is connected with a power device, the power device drives the rotation of the ash removal gear, and the rotating ash removal gear pushes the ash below the pencil block to the outside.

[0009] Compared with the prior art, the present application has the following advantages: first, by adding an ash removal gear, the present application can actively remove the pencil ash below the pencil block during pencil sharpening, avoiding the movement of the pencil block caused by the accumulation of ash. This design ensures smooth feeding of the pencil and avoids affecting the normal function of the pencil sharpener. Second, the ash removal gear is connected with a power device, which drives the rotation of the ash removal gear. Compared with the traditional passive ash removal structure, the ash removal gear can more effectively remove the ash and achieve better ash removal effect. Third, by providing the ash removal gear, the present application can reduce the accumulation of ash, improve the overall performance of the pencil sharpener, and provide users with a smoother operation experience, reducing the jam caused by the accumulation of ash. Finally, the present application adds an ash removal gear structure to the pencil sharpener, which is relatively simple in design, easy to implement and maintain, and can improve the functionality of the product without adding too much complexity.
