Description

Technical Field

[0001] The utility model relates to the technical field of knife sharpening devices, in particular to a novel knife sharpener. Background Art

[0002] Kitchen knives are essential tools in people's daily lives. For this reason, if a kitchen knife is blunt, it needs to be sharpened to make it sharp again for cutting. However, if it is not properly sharpened, it is easy to cause damage to the knife or even deformation. Since the sharpness mainly depends on the grinding angle, it is difficult for ordinary people to master and grind at a fixed angle. Ordinary people do not have the professional knife sharpening skills, so many knife sharpeners have appeared to facilitate people's use.

[0003] The current prior art CN202222828974.1 discloses a simple knife sharpener, including a positioning member and a knife sharpening member, the knife sharpening member includes a central column, a turntable and a knife sharpening part, the two sides of the central column are rotatably mounted with turntables, the knife sharpening part is mounted on the turntable, and the central column drives the turntable to rotate by hand-held translation. The utility model can position different knives through the positioning inclined surfaces of different angles on the positioning block, and the knife sharpening part is in a vertical state with a larger working surface, which can further meet the knife sharpening needs of different heights, and the two ends of the knife sharpening member have two different specifications of whetstones, which can grind the knives to different degrees as needed.

[0004] Although this application can achieve a simple structure and meet the needs of sharpening knives of different heights, since in this technology the center column drives the sharpening part to rotate simultaneously through the hand-held translation drive turntable, its main sharpening method is rotational sharpening.

[0005] Although rotary sharpening can sharpen the edge of the knife more evenly, it generally requires special sharpening equipment, which is relatively complicated to operate and requires certain skills and experience. However, translational sharpening is simple to operate and only requires holding the knife and moving it horizontally along the whetstone.

[0006] Therefore, a knife sharpener that can both rotate and translate to sharpen the knife is needed. Utility Model Content

DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] like Figures 1 to 7 As shown, a new type of knife sharpener comprises a knife sharpening member 1, which comprises a handle body 2, a handle sleeve 29 can be arranged in the middle of the handle body 2, turntables 3 are rotatably installed on both sides of the handle body 2, and sharpening parts 4 are arranged outside the turntables 3 on both sides, and the sharpening parts 4 comprise a first sharpening disc 8 and a second sharpening disc 9, which have different mesh numbers and can perform different degrees of polishing and grinding on the knives; the first sharpening disc 8 and the turntable 3 are rotatably connected to one side of the handle body 2 through a first rotating member 5, and the second sharpening disc 9 passes through the turntable 3 and is fixedly connected to the handle body 2 through a connecting member 7; the handle body 2 drives the turntable 3 to rotate by hand-held translation, and drives the first sharpening disc 8 to rotate at the same time, the first sharpening disc 8 has the same motion trajectory as the turntable 3, and the second sharpening disc 9 has the same motion trajectory as the handle body 2.

[0038] like Figures 2 to 4 As shown, a mounting hole 13 is provided on one side of the handle body 2, a first bearing 14 is provided in the mounting hole 13, and a mounting plate 15 is detachably installed on the outer side of the mounting hole 13; the first rotating member 5 includes a rotating shaft 12, one end of the rotating shaft 12 is rotatably connected to the handle body 2 through the first bearing 14, and the other end of the rotating shaft 12 passes through the mounting plate 15 and is connected to the first sharpening disk 8 and the turntable 3; the turntable 3 is installed on the outer ring of the connecting member 7 through the second rotating member 6, and the turntable 3 is placed between the second sharpening disk 9 and the handle body 2.

[0039] Specifically, two first bearings 14 are provided, a protrusion 16 is provided on the rotating shaft 12 , the protrusion 16 is placed between the two first bearings 14 , and the mounting plate 15 is placed outside the first bearings 14 .

[0040] More preferably, the distance between the bottom of the mounting hole 13 and the mounting plate 15 is equal to the sum of the widths of the two first bearings 14 and the width of the protrusion 16 .

[0041] like Figure 2 As shown, the outer side of the turntable 3 is also provided with a first magnetic component 27 and a second magnetic component 28 that can absorb the sharpening part 4. The first magnetic component 27 is arranged between the turntable 3 and the first sharpening disk 8, and the movement trajectory of the first magnetic component 27, the turntable 3, and the first sharpening disk 8 is the same; the second magnetic component 28 is connected to the connecting component 7 and is arranged between the second sharpening disk 9 and the turntable 3, and the movement trajectory of the second magnetic component 28, the second sharpening disk 9, and the handle body 2 is the same.

[0042] Specifically, the second rotating member 6 includes a second bearing 17 , the second bearing 17 is mounted on the outer ring of the connecting member 7 , and the turntable 3 is mounted on the outer ring of the second bearing 17 .

[0043] like Figure 1 and Figure 3 As shown, the knife sharpener also includes a positioning member 18, and the positioning member 18 includes a positioning block 19. The side of the positioning block 19 is provided with a positioning inclined surface 20 with a certain angle with the sharpening part 4, and the angle is 15-22°. A magnet that can absorb the knife is provided on the positioning inclined surface 20, and a pad 21 is provided on the lower side of the positioning block 19.

[0044] Specifically, the positioning bevel 20 includes a first positioning bevel 23 and a second positioning bevel 24. The first positioning bevel 23 and the second positioning bevel 24 have different angles with the grinding portion 4 and are respectively arranged on two opposite side surfaces of the positioning block 19; the other two side surfaces of the positioning block 19 are also provided with a third positioning bevel 25 and a fourth positioning bevel 26 which have different angles with the grinding portion 4.

The blade at its end protrudes downward from the positioning slope 20, and the whetstone of the sharpening part 4 is abutted against the blade of the tool. Since the two ends of the handle body 2 are connected to the sharpening part 4 by different connection methods, the sharpener has both rotational sharpening and translational sharpening methods. The handle body 2 is moved by hand, and the turntable 3 and the sharpening part 4 are driven to move, thereby completing the grinding of the blade of the tool.

[0048] The utility model connects the sharpening part 4 at both ends of the handle body 2 by different connection methods.

Not only can the cutting edge of the tool be sharpened more evenly, but it can also be suitable for tools of various sizes and shapes, and is more flexible. Since the sharpening part 4 adopts magnetic attraction to fix the two ends of the handle body 2, it is also convenient to replace sharpening discs of different mesh numbers. In addition, the positioning bevels 20 with different angles on the positioning block 19 can meet the positioning of different tools, and the heightening of the pad 21 can further meet the sharpening needs of larger tools.

[0049] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
