[0030] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0032] In a preferred embodiment, see Figures 1 to 7 , provides a pencil sharpener ash discharge structure 1, including: a base 10, a bracket body 20 and a tool holder 40, one end of the bracket body 20 is connected to the base 10, and the other end of the bracket body 20 is used to be fixedly connected to the tool holder 40, and the tool holder 40 has a certain setting height relative to the base 10; a chip storage member 30, the chip storage member 30 is movably connected to the base 10, and the chip feed opening 51 of the chip storage member 30 is set toward the tool holder 40; a guide surface 41 is provided on the side of the tool holder 40 close to the chip storage member 30, and the guide surface 41 is inclined toward the base 10, and the guide surface 41 is used to guide the pencil chips cut by the tool holder 40 into the chip storage member 30.

[0033] Among them, the pencil sharpener ash discharge structure 1 in the present application document is suitable for a tower-type pencil sharpener 2, and the pen feed hole 8 is arranged in the top area of ​​the tool holder 40. For example, the pencil to be sharpened is vertically inserted into the tool holder 40 from the pen feed hole 8. After being cut by the cutting tool in the tool holder 40, the debris falls downward along the direction of gravity. Therefore, in the present application document, a guide surface 41 is provided directly below the tool holder 40, and the guide surface 41 is inclined toward the direction of the base 10. The guide surface 41 can play a certain guiding and gathering role, avoiding the debris from flying around after being cut by the tool holder 40. The debris can fall into the chip storage part 30 along the guide surface 41, achieving a relatively good gathering effect.

[0034] Furthermore, limit baffles 42 are provided on both sides of the tool holder 40, which are connected to the guide surfaces 41, and the side walls of the limit baffles 42 are arranged close to the bracket body 20, and the bracket body 20 assists in fixing the setting position of the limit baffles 42; wherein, the limit baffles 42 cooperate with the guide surfaces 41 to introduce pencil chips into the chip storage part 30, and the limit baffles 42 are arranged on both sides of the tool holder 40, that is, there are two limit baffles 42 in the present application document, and the setting of the limit baffles 42 is to surround the tool holder 40, and then the chips cut by the tool holder 40 will be scattered and will hit the limit baffles 42. The stopping effect of the limit baffles 42 prevents the chips from scattering, and cooperates with the guide surfaces 41, so that the chips can fall into the chip storage part 30 in an orderly manner along the guide surfaces 41, reducing the impact of the dispersion of chips on the work of other components in the pencil sharpener 2.

[0035] As another preferred option, see Figure 2 and Figure 3 The limit baffle 42 is curved along the extension direction of the guide surface 41. The curved limit baffle 42 can further improve the collection effect of debris, and cooperate with the inclined guide surface 41 to prevent debris from scattering from the tail end of the limit baffle 42.

[0036] Further preferably, the pencil sharpener ash discharge structure 1 further includes: a reinforcing rib 43, one end of the reinforcing rib 43 is connected to the guide surface 41, and the other end of the reinforcing rib 43 is connected to the limit baffle 42; wherein, the reinforcing rib 43 abuts against the bracket body 20 to stop the tool holder 40 from escaping from the bracket body 20 along the inclined direction of the guide surface 41. It should be noted that the reinforcing rib 43 is a triangular structure with better supporting performance. The setting of the reinforcing rib 43 can further limit the shaking of the tool holder 40 and improve the stability of the tool holder 40 during the pencil cutting process.

[0037] Further preferably, one end of the bracket body 20 is connected to the bottom periphery of the base 10, and the other end of the bracket body 20 is connected to the side wall of the tool holder 40. The bracket body 20 is arranged at the edge of the base 10, and the bracket body 20 is inclined toward the center of the base 10. Figure 4 The setting of the bracket body 20 can maximize the chip storage space of the chip storage part 30, improve the chip storage capacity of the chip storage part 30 while ensuring the support strength, reduce the number of times the chip storage part 30 dumps the chips, and improve the practicality of the pencil sharpener 2.

[0038] Furthermore, the chip storage part 30 includes: a chip storage base plate 32 and a chip storage shell 31. The chip storage shell 31 is connected to the chip storage base plate 32. The chip storage base plate 32 is slidingly connected to the base 10, and the chip storage shell 31 extends along the extension direction of the bracket body 20. When the chip storage base plate 32 fits and covers the base 10, the chip storage shell 31 is arranged around the periphery of the base 10.

[0039] Furthermore, the chip storage shell 31 is further provided with a connecting portion 33 . When the chip storage shell 31 is arranged around the periphery of the base 10 , the connecting portion 33 abuts against the bracket body 20 .

[0040] The chip storage member 30 is specifically a cylindrical structure, and the chip storage shell 31 is arranged in a surrounding shape. The chip storage shell 31 is arranged at a high height so that the chip storage shell 31 can be covered at the height of the tool holder 40 through the connecting portion 33, thereby making the chip storage capacity of the chip storage member 30 larger. Figure 6 The guide surface 41 is close to the top area of ​​the chip storage member 30, so that the chips cut by the tool holder 40 can directly fall into the chip storage member 30 from the guide surface 41, further reducing the possibility of chips flying.

[0041] At the same time, the chip storage part 30 is slidably connected to the base 10 through a track 34, that is, during actual operation, the chip storage part 30 is connected to the base 10 in the form of a pull-out drawer, and the chip storage part 30 is convenient and quick to take out.

[0042] Furthermore, the present application also provides a pencil sharpener 2, see Figure 4 、 Figure 6 and Figure 8 The pencil sharpener 2 comprises a shell body 3, the shell body 3 is provided with an installation space, and any one of the above-mentioned pencil sharpener ash discharge structures 1 is fixedly arranged in the installation space.

[0043] Preferably, the pencil sharpener 2 further includes a motor 4, which is placed in the installation space and connected to a tool holder 40 in the pencil sharpener ash discharge structure 1, and the motor 4 drives the tool holder 40 to operate for cutting.

[0044] Among them, it should be noted that the pencil sharpener ash discharge structure 1 in the present application document is preferably applicable to an electric pencil sharpener 2 with a motor 4. Due to the existence of this structure of the motor 4, there is a need for higher management requirements for the flying landing points of debris in the pencil sharpener 2 to avoid the debris from affecting the operation of the motor 4. Therefore, the motor 4 and the tool holder 40 in the present application document are arranged on opposite sides, so that the two are as far away from each other as possible, and a shell 5 is provided on the side of the motor 4 facing the tool holder 40 to further prevent the debris generated by the cutting of the tool holder 40 from affecting the operation of the motor 4.

[0045] At the same time, the shell 5 is not fully enclosed. An opening 51 is provided on the side of the shell 5 facing the shell body 3, so that the operator can replace the motor 4 through the exposed opening 51 after removing the shell body 3, thereby reducing the difficulty of replacing the motor 4.

[0046] Preferably, the outer wall of the motor 4 facing the tool holder 40 is covered with a shell 5, and the shell 5 is provided with an opening 51 on the side close to the shell body 3, and one end of the shell 5 is directly connected to the tool holder 40, and the other end of the shell 5 is connected to the tool holder 40 through a reinforcement 6. At the same time, in order to ensure the stability of the motor 4, both sides of the motor 4 are connected. Figure 6 The top area of ​​the motor 4 is directly connected to the tool holder 40 through the housing 5, and the bottom area of ​​the motor 4 is connected to the bottom area of ​​the tool holder 40 through the housing 5 and the reinforcement 6, and the reinforcement 6 is arranged in a ring shape to avoid the falling of debris in the guide surface 41.

[0047] In a specific pencil sharpener 2, see Figure 8 A handle area 7 is defined between the shell body 3 and the chip storage member 30, which makes it easy for the user to insert his fingers into the handle area 7 to pull out the chip storage member 30 to complete the dumping of the debris, thereby increasing the operability of the pencil sharpener 2.
