[0039] The embodiment of the present application discloses a knife sharpener which is convenient for cleaning iron filings.

[0040] Embodiment 1:

[0041] Reference Figure 1 The knife sharpener includes a mounting shell 1, a driving member 2, a sharpening blade 3 and a magnet block 4. The mounting shell 1 is hollow, the driving member 2 is fixedly connected to the mounting shell 1, the sharpening blade 3 is rotatably connected to the mounting shell 1, and the driving member 2 drives the sharpening blade 3 to rotate, thereby sharpening the tool. The magnet block 4 is detachably connected to the mounting shell 1, and the magnet block 4 is located on the peripheral side of the sharpening blade 3 to absorb iron filings produced during tool grinding. In this embodiment, the shape of the magnet block 4 is a rectangular block to increase the adsorption area. In other embodiments, the shape of the magnet block 4 can also be a circular block, a polygonal block, etc., which is not limited in this application.

[0042] In actual application, the driving member 2 drives the grinding blade 3 to rotate, and the tool contacts and moves with the grinding blade 3 to grind the tool. The iron filings generated by the tool during the grinding process are adsorbed by the magnet block 4 located on the side of the grinding blade 3 to avoid the occurrence of iron filings splashing. In addition, when cleaning the iron filings in the mounting shell 1, it can be achieved by disassembling the magnet block 4, so that it is convenient to clean the iron filings in the mounting shell 1.

[0043] Reference Figure 2In some embodiments, the mounting shell 1 protrudes inward to form two clamping columns 11, the two clamping columns 11 are arranged opposite to each other and have a certain elasticity, and the magnet block 4 is elastically clamped between the two clamping columns 11 and the mounting shell 1, thereby realizing a detachable connection between the magnet block 4 and the mounting shell 1, and the detachable structure is simple and easy to operate, which facilitates the disassembly and cleaning of the magnet block 4, and further facilitates the cleaning of iron filings in the mounting shell 1.

[0044] In some embodiments, a slot 111 is provided on one end of the clamping column 11 close to the mounting shell 1 and on one side close to another clamping column 11, and the magnet block 4 is clamped in the two slots 111, so that the clamping column 11 can limit the magnet block 4 to improve the stability of the clamping of the magnet block 4, and can effectively prevent the magnet block 4 from detaching from the two clamping columns 11 when the sharpener is in use, thereby improving the stability of the magnet block 4 in absorbing iron filings.

[0045] In some embodiments, a chamfer 112 is provided on one end of the clamping column 11 away from the mounting shell 1 and on one side close to another clamping column 11. When the magnet block 4 is clamped in the two clamping grooves 111, the magnet block 4 abuts against the two chamfers 112, so that the two clamping columns 11 are elastically deformed to guide the clamping of the magnet block 4, thereby facilitating the installation of the magnet block 4.

[0046] In some embodiments, the mounting shell 1 also protrudes to form a plurality of limit blocks 12. In this embodiment, the number of the limit blocks 12 is four, wherein two limit blocks 12 are located on one side of the clamping column 11, and the other two limit blocks 12 are located on the other side of the clamping column 11, so that the four limit blocks 12 and the two clamping columns 11 are distributed in a rectangular shape, so that the magnet block 4 is clamped between the four limit blocks 12 and the two clamping columns 11, which can improve the accuracy of the clamping position of the magnet block 4, so as to improve the adsorption efficiency of iron filings, and can also improve the clamping stability of the magnet block 4.

[0047] In some embodiments, the mounting shell 1 is provided with a clearance groove 13 between the two clamping columns 11, and the clearance groove 13 is used to lift the magnet block 4, so as to facilitate the removal of the magnet block 4. In this embodiment, there are two clearance grooves 13 to facilitate lifting the magnet block 4.

[0048] The implementation principle of this embodiment is as follows: in actual application, the driving member 2 drives the grinding blade 3 to rotate, and the tool contacts and moves with the grinding blade 3 to grind the tool, wherein the iron filings generated by the tool during the grinding process are adsorbed by the magnet block 4 located on the side of the grinding blade 3, so as to avoid the occurrence of iron filings splashing. In addition, when cleaning the iron filings in the mounting shell 1, it can be achieved by disassembling the magnet block 4, so as to facilitate the cleaning of the iron filings in the mounting shell 1.

Specifically, the sharpener also includes a mounting seat 5, one end of the mounting seat 5 is provided with a mounting groove 51, and the magnet block 4 is clamped in the mounting groove 51. At the same time, the mounting shell 1 is protruded to form a connecting column 14. Among them, the outer peripheral side of the mounting seat 5 has an external thread, and the inner peripheral side of the connecting column 14 has an internal thread. The threaded connection between the mounting seat 5 and the connecting column 14 is realized by the external thread and the internal thread, so as to realize the detachable connection between the magnet block 4 and the mounting shell 1. In addition, the setting of the connecting column 14 can ensure that the mounting shell 1 is threadedly connected to the mounting seat 5 when it is thin, so that the processing and production of each component is simpler. It should be noted that a plurality of magnet blocks 4 can be set according to the position and number of the sharpening blades 3.

[0052] In some embodiments, the magnet block 4 protrudes from the mounting groove 51 to increase the adsorption area of ​​the magnet block 4 , thereby improving the adsorption efficiency of the magnet block 4 on iron filings.

[0053] In some embodiments, a pick-up and release groove 53 is opened on the peripheral side of the mounting seat 5, and the pick-up and release groove 53 is connected to the mounting groove 51, and there is a gap between the end of the magnet block 4 close to the rotating hole 52 and the bottom wall of the mounting groove 51. The hand can be inserted into the gap through the pick-up and release groove 53 to facilitate the removal of the magnet block 4 from the mounting seat 5, thereby facilitating the cleaning of the magnet block 4 and facilitating the replacement of the magnet block 4.
