Technical Field
[0001] The present application belongs to the technical field of kitchenware manufacturing, and specifically relates to an anti-stick device for kitchen knives. Background Art
[0002] When a kitchen knife is cutting food into slices, the sliced food tends to stick to the knife, especially for sticky food such as potatoes and meat. Therefore, the cutter needs to stop frequently during the cutting process to remove the sliced food stuck to the knife, which makes the cutting efficiency very low. Summary of the invention
[0003] The purpose of the present application is to address the shortcomings of the prior art and to design a kitchen knife slice anti-stick device by arranging a roller on a frame, so that when cutting vegetables, the frame is first fixed to the side of the kitchen knife facing away from the chef, and then the cut sliced food is separated from the uncut food under the rolling action of the roller, thereby solving the problem that the cut sliced food is easy to stick to the knife.
[0004] To achieve the above objectives, this application provides the following technical solutions:
[0005] A kitchen knife slice anti-sticking device comprises a frame body, on which a roller protruding from the surface of the frame body is provided.
[0006] Preferably, the roller is arranged on the front side of the frame.

[0009] Preferably, the roller comprises a plurality of rollers rotatably arranged on the frame, all of the rollers are parallel to each other, and the rollers are parallel to the front of the frame and perpendicular to the connecting line segment between the upper and lower ends of the frame.
[0010] Preferably, between any two longitudinally adjacent rollers on the frame, the diameter of the roller relatively located below is smaller than the diameter of the roller relatively located above, and all the rollers have a common tangent surface on the side facing away from the frame.
[0011] Preferably, each of the rollers is radially provided with protrusions.

[0016] Preferably, the frame and the roller are both made of hard rubber.
[0017] Compared with the prior art, the beneficial effects of this application are:
[0018] 1. The present application adopts the method of setting a roller on a frame to design a kitchen knife slice anti-stick device, so that when cutting vegetables, the frame is first fixed on the side of the kitchen knife facing away from the chef, and then the cut sliced food is separated from the uncut food under the rolling action of the roller, thereby solving the problem that the cut sliced food is easy to stick to the knife.

DETAILED DESCRIPTION
[0028] See also Figure 1-7 A kitchen knife slice anti-sticking device comprises a frame 1, on which a roller protruding from the surface of the frame 1 is provided.
[0029] In this embodiment, during use, the frame 1 is first fixed to the side of the kitchen knife 9 facing away from the cutter. When cutting vegetables, the user presses the kitchen knife 9 downward, and the blade of the kitchen knife 9 enters the food 12. The sheet portion 11 of the food 12 contacts the roller on the side of the food 12 facing the cutter's hand-gripping portion 10. Since the roller rolls, the friction between the roller and the sheet portion 11 can be reduced, and no resistance to cutting vegetables is brought to the cutter. At the same time, due to the rolling of the roller and the roller protruding from the surface of the frame 1, there is no negative pressure between the sheet portion 11 and the roller, causing them to stick together (when the kitchen knife 9 cuts potato slices, there are two reasons why the cut potato slices are close to the kitchen knife 9. One is that the close contact with the kitchen knife 9 causes negative pressure to be formed between the cut potato slices and the side of the kitchen knife 9 facing away from the cutter; the other reason is that the starch in the potatoes has a certain viscosity after meeting water and sticks to the knife).
[0030] As a preferred embodiment, the roller is arranged on the front side of the frame 1; that is, when installed on the kitchen knife 9, the back side of the frame 1 is fixedly connected to the side of the kitchen knife 9 facing away from the cutter, and the front side of the frame 1 faces the sliced portion 11 of the food 12.
[0031] As a preferred mode, the distance between the side of the roller facing away from the front of the frame 1 and the front of the frame 1 gradually increases from the lower end of the frame 1 to the upper end of the frame 1. The reason for this arrangement is that, during the process of the kitchen knife 9 cutting into the food, since the roller at the lower end of the frame 1 is relatively small, it is easy to follow the kitchen knife 9 into the gap between the sheet portion 11 and the hand-grip portion 10 of the vegetable cutter. As the kitchen knife 9 enters deeper into the food, since the roller at the upper end of the frame 1 is relatively large, the gap between the upper end of the sheet portion 11 and the hand-grip portion 10 of the vegetable cutter is expanded by the roller at the upper end of the frame 1, and then the sheet portion 11 is tilted away from the hand-grip portion 10 of the vegetable cutter due to the unstable center of gravity, thereby achieving the purpose of preventing the sheet portion 11 from sticking to the kitchen knife 9.
[0032] As a preferred embodiment, the roller includes a plurality of balls 2 rolling on the frame 1, the diameter of the ball 2 relatively located below the frame 1 is smaller than the diameter of the ball 2 relatively located above the frame 1, and all the balls 2 on the frame 1 have a co-tangent surface on the side facing away from the front of the frame 1.
[0033] In this way, by arranging the sphere 2, the cut-off area of the sphere 2 and the sheet part 11 is reduced during the vegetable cutting process, thereby preventing the sheet part 11 from sticking to the roller; secondly, since all the spheres 2 have a common cut surface, the process of gradually increasing the diameter of the sphere 2 from the lower end to the upper end of the frame 1 is gradual, thereby preventing the sphere 2 relatively located at the upper end of the frame 1 from suddenly increasing in diameter, resulting in the sphere 2 relatively located at the upper end of the frame 1 directly pressing the top of the sheet part 11 during the vegetable cutting process, thereby affecting the subsequent frying, stir-frying, and food taste of the chef. At the same time, the arrangement of the sphere 2 allows the knife 9 to generate rolling friction while moving along the axial direction of the handle of the knife 9 (this action is usually called cutting in life), in addition to reducing the friction between the frame 1 and the sheet portion 11 during the downward movement of the knife 9 during the process of cutting vegetables. This can also reduce the friction between the frame 1 and the sheet portion 11 (this advantage is not available when the roller 3 is used as the setting).
[0034] Preferably, Figure 5 As shown, the difference between the diameter of the sphere 2 located relatively above and the diameter of the sphere 2 located relatively below between two longitudinally adjacent spheres 2 on the frame 1 is 3 mm.
[0035] As a preferred embodiment, the roller includes a plurality of rollers 3 rotatably arranged on the frame 1, all of the rollers 3 are parallel to each other, and the rollers 3 are parallel to the front surface of the frame 1 and perpendicular to the connecting line segment between the upper and lower ends of the frame 1.
[0036] Compared with the method of setting the roller as a sphere 2, the method of setting the roller as a roller 3 reduces the difficulty of manufacturing process and also reduces the manufacturing cost. Because the spheres 2 need to be arranged in several rows on the front of the frame 1, with several spheres in each row. If the roller 3 is used, one roller can be equivalent to one row of spheres 2.
[0037] As a preferred embodiment, between any two longitudinally adjacent rollers 3 on the frame 1, the diameter of the roller 3 relatively located below is smaller than the roller 3 relatively located above, and all the rollers 3 have a common tangent surface on the side facing away from the frame 1.
[0038] After such arrangement, during the process of the kitchen knife 9 cutting into the food, since the diameter of the roller 3 located at the lower end of the frame 1 is relatively small, it is easy to follow the kitchen knife 9 into the gap between the sheet portion 11 and the vegetable cutter's hand grip portion 10. As the kitchen knife 9 enters deeper into the food, since the diameter of the roller 3 located at the upper end of the frame 1 is relatively large, the gap between the upper end of the sheet portion 11 and the vegetable cutter's hand grip portion 10 is expanded by the roller 3 located at the upper end of the frame 1, and then the sheet portion 11 is tilted away from the vegetable cutter's hand grip portion 10 due to the unstable center of gravity, thereby achieving the purpose of preventing the sheet portion 11 from sticking to the kitchen knife 9.
[0039] As a preferred mode, each roller 3 is radially provided with convex particles 4. The purpose of providing the convex particles 4 is to reduce the contact area between the roller 3 and the sheet-like portion 11, thereby reducing the probability of the roller 3 and the sheet-like portion 11 sticking together.
[0040] As a preferred embodiment, all the protrusions 4 on the same roller 3 have the same length.
[0041] As a preferred embodiment, a plurality of support rods 5 are radially provided on each of the rollers 3, and the length of the support rod 5 on the roller 3 relatively located below between any two longitudinally adjacent rollers 3 on the frame 1 is smaller than the length of the support rod 5 on the roller 3 relatively located above, and the projections of the ends of all the support rods 5 on the same roller 3 facing away from the roller 3 on the cross section of the roller 3 are located on a virtual circle 6, and all the virtual circles 6 on the rollers 3 have a common tangent 7.
[0042] This arrangement is intended to reduce the contact area between the roller 3 and the sheet portion 11. At the same time, since the length of the relatively lower roller 3 is smaller than the relatively upper roller 3, the sheet portion 11 is easy to fall away from the cutter during the cutting process, and more air can enter between the sheet portion 11 and the cutter's hand-held portion 10.
[0043] As a preferred manner, the frame 1 is provided with a snap fit 8 which cooperates with the kitchen knife 9. By providing the snap fit 8, it is convenient to fix the frame 1 on the kitchen knife 9. In practical applications, the snap fit 8 can be a neodymium iron boron magnet; or two holes can be provided on the kitchen knife 9, and then two holes are also provided on the frame 1, and then the frame 1 and the kitchen knife 9 are locked together by bolts.
[0044] As a preferred embodiment, the frame 1 and the roller are both transparent structures, which makes it convenient for the vegetable cutter to grasp the cutting position on the food 12 during the cutting process.
[0045] As a preferred method, the frame 1 and the roller are both made of hard rubber, which is relatively light in weight and can be made by a mold during the manufacturing process, which is relatively convenient.

There are two first support arms 1-2 arranged at the upper end of the rectangular frame 1-1, and the two first support arms 1-2 are parallel to each other. The two first support arms 1-2 correspond to the two ends of the roller 3 respectively, and the two first support arms 1-2 are connected together by a fixing rod 1-3, and the fixing rod 1-3 is parallel to the back side of the rectangular frame 1-1, and the connection point between the fixing rod 1-3 and the first support arm 1-2 is located between the two ends of the first support arm 1-2, and each first support arm 1-2 is provided with a first top claw 1-4 on the side of the fixing rod 1-3 facing away from the rectangular frame 1-2, one end of the first top claw 1-4 is fixedly connected to the first support arm 1-2, and the other end is a free end, and the two first top claws 1-4 are both located between the two first support arms 1-2, and the first top claw 1-4 is provided with a screw hole matching the screw 1-5, and the axis of the screw hole is parallel to the first support arm 1-2.
