Technical Field
[0001] This invention relates to the field of knife sharpener technology, and more particularly to a novel knife sharpener. Background Technology
[0002] A knife sharpener is a tool used to sharpen knives, enabling dull knives to regain their sharpness. Currently, common knife sharpeners on the market are mainly divided into: carbide sharpeners, ceramic sharpeners, and oilstone sharpeners. While carbide sharpeners can achieve the desired sharpening effect, they easily produce metal shavings during use; ceramic sharpeners are brittle and easily damaged or broken; oilstone sharpeners usually require hand-holding, can only sharpen one side at a time, are difficult to control, and are inefficient. Therefore, there is an urgent need for a high-efficiency, durable knife sharpener with good sharpening effects.
[0003] A search revealed Chinese patent application CN201020647171.0, which discloses a knife sharpener consisting of an end cap, a V-shaped sharpening wheel, a V-shaped fine sharpening stone, a central shaft of the sharpening wheel, and a handle. The V-shaped sharpening wheel has a slightly coarser grit for rough sharpening, while the V-shaped fine sharpening stone has a very fine grit for fine sharpening. The knife sharpener in this patent has the following shortcomings: although a V-shaped sharpening wheel is designed for simultaneous sharpening of both sides, the fixed angle of the V-groove makes it difficult to achieve a tight fit with the blade edge, and it is also difficult to adapt to knives of different thicknesses, resulting in poor sharpening performance. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel knife sharpener.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A new type of knife sharpener includes:
[0007] A sharpening box, wherein a first pad assembly and a second pad assembly are provided on the inner wall of the bottom of the sharpening box;
[0008] The first whetstone is placed on the first pad assembly;

[0013] The bottom surface of the first whetstone is inclined. Due to gravity, the bottom surface of the first whetstone is in contact with the top surface of the first pad assembly, thereby forming a gap between the side surface of the first whetstone and the first positioning assembly.
[0014] In addition, the height of the first whetstone is higher than the height of the second whetstone.
[0015] Preferably, the first pad assembly includes a first raised portion and a second raised portion, wherein the height of the first raised portion is higher than the height of the second raised portion, causing one end of the first whetstone to be raised.

[0029] As a further embodiment of the present invention: the bottom outer wall of the grinding box is integrally provided with foot blocks.
[0030] Based on the aforementioned solution: the first raised portion includes: a first inclined pad block;
[0031] The second raised portion includes: a second inclined pad;
[0032] Both the first and second raised portions include: a first flat pad;
[0033] The second pad assembly includes a second flat pad, which has the same specifications as the first flat pad.
[0034] Based on the aforementioned scheme, the preferred embodiment is as follows: the bottom of the first inclined pad, the second inclined pad, the first flat pad, and the second flat pad are all integrally provided with insert posts, and the bottom inner wall of the grinding box and the top outer wall of the first flat pad and the second flat pad are all provided with slots that are compatible with the insert posts.
[0035] Based on the aforementioned solution, the preferred embodiment includes: both the first raised portion and the second raised portion comprising:
[0036] Adjustable pad, with multiple adjustment chambers on the adjustable pad;
[0037] An adjusting screw is threadedly connected to the inner wall at the bottom of the adjusting cavity.
[0038] The ball seat is slidably connected to the inner wall of the adjustment cavity, and the top of the adjustment screw is rotatably mounted on the bottom inner wall of the ball seat.
[0039] The ball bearing is mounted on the top of the ball seat, and its diameter is larger than the inner diameter of the top of the adjusting cavity.
[0040] A preferred embodiment based on the aforementioned solution is: a handle assembly is provided on one side of the sharpening box, the handle assembly comprising:
[0041] The handle has a clamping bracket fixed to one outer wall.
[0042] The threaded column is connected to the inner wall of the bottom of the clamping frame by threads, and a knob is integrally set at the bottom end of the threaded column;
[0043] The clamping plate has a guide rod fixed at its bottom, which is slidably connected to the inner wall of the bottom of the clamping frame, and the top of the threaded column is rotatably connected to the inner wall of the clamping plate.
[0044] A base block is provided on one side of the sharpening box. The dimensions of the clamping plate and the base block are adapted to the base block, and the height of the base block is adapted to the first sharpening stone and the second sharpening stone.
[0045] Preferably based on the foregoing solution: The sharpener is also used in cooperation with a chopping board; a jack is provided on the chopping board; side brackets are provided on the outer walls on both sides of the first top cover and the second top cover, and the chopping board is detachably installed on the side brackets through the jack, and the chopping board has a "匚"-shaped structure adapted to the first top cover and the second top cover; a leg is fixed to the bottom of one side of the chopping board, and anti-slip feet are fixed to the outer wall of the bottom of the磨刀盒 and the bottom end of the leg.
[0046] Preferably based on the foregoing solution: A fixed buckle is fixed to the outer wall of the top of the chopping board, and an elastic liquid bladder is clamped on the fixed buckle. One end of the elastic liquid bladder is provided with a spray pipe, and the position of the spray pipe is adapted to the installation positions of the first sharpening stone and the second sharpening stone.
[0047] The beneficial effects of the present invention are:
[0048] 1. By providing structures such as the first sharpening stone and the second sharpening stone, the present invention can insert the knife into the grinding channel during use and perform pulling and grinding, achieving the purpose of grinding both sides of the knife simultaneously; the whole device is simple to operate, has a good grinding effect, and a long service life.
[0049] 2. Since the height of the first sharpening stone is higher than the height of the second sharpening stone in the present invention, it is more convenient to insert the knife, and it is easier to insert the knife into the grinding channel.
[0050] 3. Since the bottom surface of the first sharpening stone is an inclined surface in the present invention, based on gravity, the bottom surface of the first sharpening stone fits against the top surface of the first cushion block assembly; when the knife is inserted into the grinding channel, the thickness of the knife is greater than the width of the current grinding channel, and the first sharpening stone will necessarily be squeezed towards the side close to the first positioning component. At this time, the gap width decreases and the width of the grinding channel increases, making it adaptable to the size of the knife. At the same time, since the bottom surface of the first sharpening stone is an inclined surface, there is a force decomposed based on gravity between the first sharpening stone and the knife, thus ensuring the grinding effect and improving the grinding efficiency.
[0051] 4. By providing the first elevation part and the second elevation part with different heights, when the knife is pulled once, the contact area between the side of the knife body and the first sharpening stone is larger than the contact area when the first sharpening stone is in a flat state, improving the grinding effect.
[0052] 5. By providing structures such as threaded columns and threaded parts, the position of the threaded column can be adjusted by screwing the threaded part, and then the positions of the first push plate and the second push plate can be changed, ultimately achieving the purpose of adjusting the positions of the first push plate and the second push plate, improving the practicability; by providing a拨片, it is convenient to screw the threaded part, achieving a labor-saving effect.
[0053] 6. By providing the first top cover and the second top cover, the internal structure of the sharpener can be protected, improving the aesthetics and practicability.
[0054] 7. By setting a first inclined pad, a second inclined pad, a first flat pad, and a second flat pad, the present invention can adjust the height of the first and second whetstones according to needs by adding different numbers of the first and second flat pads, thus improving practicality; by setting a post and a slot, splicing and fixing can be achieved by inserting the post into the slot, thus improving practicality.
[0055] 8. By setting adjustable pads, balls, and other structures, the present invention can adjust the position of the ball seat and the height of the balls by turning the adjusting screws as needed, thereby changing the support effect on the first and second whetstones; thus changing the deflection angle of the first and second whetstones and improving practicality.
[0056] 9. By providing a handle assembly, the present invention can clamp the clamping frame and clamping plate onto the base block, thereby installing the handle assembly onto the sharpening box. When using the knife, the user can hold the handle to apply force. In addition, the user can install the first or second sharpening stone inside the clamping frame and clamping plate for independent use, which provides high flexibility.
[0057] 10. By incorporating structures such as a cutting board, this invention facilitates the combination of the cutting board and the knife sharpener, thus enhancing practicality. Furthermore, by incorporating structures such as an elastic liquid bladder, water can be output from the nozzle by squeezing the elastic liquid bladder, facilitating smoother sharpening and further enhancing practicality.

[0071] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0072] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.
[0073] Example 1:
[0074] A new type of knife sharpener, such as Figure 1-6 As shown, it includes:
[0075] Sharpening box 1, wherein a first pad assembly and a second pad assembly are provided on the bottom inner wall of the sharpening box 1;
[0076] The first whetstone 3 is placed on the first pad assembly;
[0077] The second whetstone 11 is placed on the second pad assembly;
[0078] The first positioning component is disposed on the side of the first whetstone 3 away from the second whetstone 11, and is used to limit and support one side of the first whetstone 3.
[0079] The second positioning component is disposed on the side of the second whetstone 11 away from the first whetstone 3, and is used to limit and support one side of the second whetstone 11.
[0080] The first whetstone 3 and the second whetstone 11 have adjacent grinding surfaces and form a grinding channel 14. The whetstone box 1 has openings 9 on both sides, and the positions of the openings 9 are adapted to the grinding channel 14.
[0081] The bottom surface of the first whetstone 3 is inclined. Due to gravity, the bottom surface of the first whetstone 3 is in contact with the top surface of the first pad assembly, thereby forming a gap 15 between the side surface of the first whetstone 3 and the first positioning assembly.
[0082] Furthermore, the height of the first whetstone 3 is higher than the height of the second whetstone 11;
[0083] By setting up structures such as the first whetstone 3 and the second whetstone 11, the knife can be inserted into the grinding channel 14 during use and pulled out for grinding, thus achieving the purpose of grinding both sides of the knife at the same time.
[0084] In addition, since the height of the first whetstone 3 is higher than that of the second whetstone 11, it is easier to insert the knife into the grinding channel 14.
[0085] Furthermore, since the bottom surface of the first whetstone 3 is inclined, it adheres to the top surface of the first pad assembly due to gravity. When the blade is inserted into the grinding channel 14, the thickness of the blade is greater than the width of the current grinding channel 14, which will inevitably push the first whetstone 3 towards the side closer to the first positioning assembly. At this time, the width of the gap 15 decreases and the width of the grinding channel 14 increases, so that it can fit the size of the blade. At the same time, since the bottom surface of the first whetstone 3 is inclined, there is a force between the first whetstone 3 and the blade based on gravity decomposition, thereby ensuring the grinding effect and improving the grinding efficiency.
[0086] The entire device is easy to operate, produces excellent polishing results, and has a long service life.
[0087] To increase the polishing range, such as Figure 1 , Figure 5 As shown, the first pad assembly includes a first raised part and a second raised part, the height of the first raised part is higher than the height of the second raised part, causing one end of the first whetstone 3 to be raised.
[0088] By setting up a first and a second raised part with different heights, when the tool completes one pull, the contact area between the side of the blade and the first whetstone 3 is greater than the contact area when the first whetstone 3 is pulled out in a flat state, thus improving the grinding effect.
[0089] To facilitate the positioning and limiting of the first whetstone 3 and the second whetstone 11; such as Figure 1-3 As shown, the first positioning component includes:
[0090] The first push plate 16 is slidably connected to the inner wall of the sharpening box 1;
[0091] The first spring has its two ends fixed to the outer wall of one side of the first push plate 16 and the inner wall of one side of the sharpening box 1, respectively.
[0092] The first limiting member is used to limit the first push plate 16;
[0093] The second positioning component includes:
[0094] The second push plate 12 is slidably connected to the inner wall of the sharpening box 1;
[0095] The second spring 13 has its two ends fixed to the outer wall of one side of the second push plate 12 and the inner wall of one side of the sharpening box 1, respectively.
[0096] The second limiting member is used to limit the second push plate 12.
[0097] To facilitate adjustment of the positions of the first push plate 16 and the second push plate 12; such as Figure 1-3 As shown, both the first limiting member and the second limiting member include:
[0098] Threaded post 6, one end of which is fixed to the side wall of the first push plate 16 or the side wall of the second push plate 12;
[0099] Threaded component 8 is connected to the outer wall of one end of threaded post 6 by a thread. Threaded component 8 is located outside the grinding box 1. The second spring 13 is in a compressed state.
[0100] By setting up structures such as threaded post 6 and threaded component 8, the position of threaded post 6 can be adjusted by screwing on threaded component 8, thereby changing the position of first push plate 16 and second push plate 12, ultimately achieving the purpose of adjusting the position of first push plate 16 and second push plate 12, thus improving practicality.
[0101] To facilitate tightening of threaded parts 8; such as Figure 1 As shown, the threaded component 8 has a paddle 7 integrally provided on both outer walls;
[0102] By setting the lever 7, it is easy to tighten the threaded part 8, thus achieving the effect of saving effort.
[0103] To improve reliability; such as Figure 1 , Figure 2 As shown, the top of the sharpening box 1 is detachably mounted with a first top cover 5 and a second top cover 2 by fastening screws 4. The first top cover 5 is located on one side of the first sharpening stone 3, and the second top cover 2 is located on the top of the second sharpening stone 11.
[0104] By setting the first top cover 5 and the second top cover 2, the internal structure of the sharpening box 1 can be protected, improving both aesthetics and practicality.
[0105] To improve practicality; such as Figure 1 As shown, the bottom outer wall of the sharpening box 1 is integrally provided with foot blocks 10.
[0106] In this embodiment, by turning the threaded part 8 with the lever 7, the first whetstone 3 and the second whetstone 11 are adjusted to the appropriate position, and the knife is inserted into the grinding channel 14 for pull-out grinding. Since the height of the first whetstone 3 is higher than the height of the second whetstone 11, it is easier to put the knife down and insert the knife into the grinding channel 14.
[0107] Furthermore, since the bottom surface of the first whetstone 3 is inclined, it adheres to the top surface of the first pad assembly due to gravity. When the blade is inserted into the grinding channel 14, the thickness of the blade is greater than the width of the current grinding channel 14, which will inevitably push the first whetstone 3 towards the side closer to the first positioning assembly. At this time, the width of the gap 15 decreases and the width of the grinding channel 14 increases, so that it can fit the size of the blade. At the same time, since the bottom surface of the first whetstone 3 is inclined, there is a force between the first whetstone 3 and the blade based on gravity, thereby ensuring the grinding effect and improving the grinding efficiency.
[0108] Example 2:
[0109] A new type of knife sharpener, such as Figure 1 As shown, in order to facilitate the adjustment of the height of the first whetstone 3 and the second whetstone 11, this embodiment makes the following improvements based on embodiment 1:
[0110] The first raised portion includes: a first inclined pad 20;
[0111] The second raised portion includes: a second inclined pad 17;
[0112] Both the first and second raised portions include: a first flat pad 18;
[0113] The second pad assembly includes: a second flat pad 19, which has the same specifications as the first flat pad 18;
[0114] By setting the first inclined pad 20, the second inclined pad 17, the first flat pad 18, and the second flat pad 19, the height of the first whetstone 3 and the second whetstone 11 can be adjusted according to the needs by adding different numbers of the first flat pad 18 and the second flat pad 19, thus improving practicality.
[0115] For ease of disassembly and assembly; such as Figure 6 As shown, the bottom of the first inclined pad 20, the second inclined pad 17, the first flat pad 18, and the second flat pad 19 are all integrally provided with insert posts 22, and the bottom inner wall of the sharpening box 1 and the top outer wall of the first flat pad 18 and the second flat pad 19 are all provided with slots 21 that are adapted to the insert posts 22.
[0116] By setting up the insert post 22 and the slot 21, splicing and fixing can be achieved by inserting the insert post 22 into the slot 21, which improves practicality.
[0117] Example 3:
[0118] A new type of knife sharpener, such as Figure 7-12 As shown, in order to facilitate the adjustment of the height of the first whetstone 3 and the second whetstone 11, this embodiment makes the following improvements based on embodiment 1:
[0119] Both the first raised portion and the second raised portion include:
[0120] Adjustable pad 40, with multiple adjustment chambers 42 provided on the adjustable pad 40;
[0121] Adjusting screw 39 is threadedly connected to the bottom inner wall of adjusting cavity 42;
[0122] Ball seat 38 is slidably connected to the inner wall of the adjustment cavity 42, and the top of the adjustment screw 39 is rotatably mounted on the bottom inner wall of the ball seat 38.
[0123] Ball bearing 41 is movably mounted on the top of ball seat 38, and the diameter of ball bearing 41 is larger than the inner diameter of the top of the adjusting cavity 42;
[0124] By setting structures such as adjustable pads 40 and balls 41, the position of the ball seat 38 can be adjusted according to requirements by screwing the adjusting screw 39, thereby adjusting the height of the balls 41, and then changing the supporting effect on the first sharpening stone 3 and the second sharpening stone 11; this causes the deflection angles of the first sharpening stone 3 and the second sharpening stone 11 to change, enhancing the practicality.
[0125] A handle assembly is provided on one side of the sharpening box 1, and the handle assembly includes:
[0126] A handle 29, with a clamping bracket 32 fixed to the outer wall on one side of the handle 29;
[0127] A threaded column 36, which is threadedly connected to the inner wall of the bottom of the clamping bracket 32, and a knob 35 is integrally provided at the bottom end of the threaded column 36;
[0128] A clamping plate 33, with a guide rod 37 fixed to the bottom of the clamping plate 33, the guide rod 37 is slidably connected to the inner wall of the bottom of the clamping bracket 32, and the top of the threaded column 36 is rotatably connected to the inner wall of the clamping plate 33;
[0129] A base block 34 is provided on one side of the sharpening box 1, the sizes of the clamping plate 33 and the base block 34 are adapted to the base block 34, and the height of the base block 34 is adapted to the first sharpening stone 3 and the second sharpening stone 11;
[0130] By setting the handle assembly, the clamping bracket 32 and the clamping plate 33 can be clamped on the base block 34, thereby installing the handle assembly on the sharpening box 1. When in use, the user can hold the handle 29 for easy application of force; in addition, the user can install the first sharpening stone 3 or the second sharpening stone 11 inside the clamping bracket 32 and the clamping plate 33 for separate use, with strong flexibility.
[0131] To enhance practicality, as Figure 8 shown, the sharpener is also used in combination with a cutting board 26; a jack 30 is provided on the cutting board 26; side brackets 23 are provided on the outer walls of both sides of the first top cover 5 and the second top cover 2, and the cutting board 26 is detachably installed on the side brackets 23 through the jack 30, and the cutting board 26 has a "匚"-shaped structure adapted to the first top cover 5 and the second top cover 2; a leg 27 is fixed to the bottom of one side of the cutting board 26, and anti-slip feet 28 are fixed to the outer wall of the bottom of the sharpening box 1 and the bottom end of the leg 27;
[0132] By setting structures such as the cutting board 26, it is convenient to use the cutting board 26 in combination with the sharpener, enhancing the practicality.
[0133] A fixed buckle 24 is fixed to the outer wall of the top of the cutting board 26, a elastic liquid bag 25 is clamped on the fixed buckle 24, and a spray pipe 31 is provided at one end of the elastic liquid bag 25, and the position of the spray pipe 31 is adapted to the installation positions of the first sharpening stone 3 and the second sharpening stone 11;

The first whetstone (3) is placed on the first pad assembly; The second whetstone (11) is placed on the second pad assembly; The first positioning component is disposed on the side of the first whetstone (3) away from the second whetstone (11) and is used to limit and support one side of the first whetstone (3). The second positioning component is disposed on the side of the second whetstone (11) away from the first whetstone (3) and is used to limit and support one side of the second whetstone (11). Among them, the grinding surfaces of the first whetstone (3) and the second whetstone (11) are adjacent and form a grinding channel (14). The whetstone box (1) has openings (9) on both sides, and the positions of the openings (9) are adapted to the grinding channel (14).

Based on gravity, the bottom surface of the first whetstone (3) is in contact with the top surface of the first pad assembly, and thus a first gap (15) is formed between the side of the first whetstone (3) and the first positioning assembly. When the knife is inserted into the grinding channel, the thickness of the knife is greater than the width of the current grinding channel, which will inevitably push the first whetstone towards the side closer to the first positioning assembly. At this time, the width of the first gap decreases and the width of the grinding channel increases, so that it can fit the size of the knife. At the same time, since the bottom surface of the first whetstone is inclined, a second gap is formed between the bottom surface of the first whetstone and the top surface of the first pad assembly. There is a force based on gravity decomposition between the first whetstone and the knife. The height of the first whetstone (3) is higher than the height of the second whetstone (11).
