Abstract
Description
Technical Field
[0001] This utility model belongs to the field of kitchenware technology, and specifically relates to a knife treated with UTi technology. Background Technology
[0002] Knives are common kitchen utensils and are essential tools for cutting vegetables, meat, and other food.
[0003] In existing technology, most kitchen knives are made of iron substrate through a certain forging process. However, iron kitchen knives are very prone to rust and corrosion by salt and other substances, which places high demands on daily maintenance. To avoid rusting and corrosion, some manufacturers choose to apply special anti-corrosion coatings to the surface of the knives, isolating the metal substrate of the knife from direct contact with water, salt, etc., thereby improving rust resistance and also enhancing the appearance.
[0004] However, this type of coating is generally easy to peel off, which affects its long-lasting anti-corrosion performance. Furthermore, if the peeled coating is ingested by the human body, it will have some impact on health. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a cutting tool treated with UTi technology.
[0006] To achieve the innovative objectives of this utility model, the following technical solutions can be used: A cutting tool treated with UTi technology includes a cutting body and a shank disposed at one end of the cutting body. The cutting body includes a metal base layer, and titanium metal layers are provided on both sides of the metal base layer. The titanium metal layers are thermally diffused and bonded to the metal base layer.
[0007] The main body of this utility model is in the form of a conventional kitchen knife, consisting of a blade and a handle. Notably, the blade body has a titanium layer on top of a metal base, enhancing its rust and corrosion resistance. This titanium layer is processed onto the metal base using UTi technology. Specifically, UTi technology involves applying a bias voltage and high current to titanium metal at 1000℃ to form ions. These ions then diffuse with the metal substrate through thermal diffusion, achieving the effect of the titanium layer penetrating into the metal base. In short, the titanium layer and the metal base are bonded through thermal diffusion, unlike coating processes. This thermal diffusion method creates a mutually fused and permeable structure, making the titanium layer less prone to peeling off.
[0008] In the aforementioned UTi-treated cutting tools, the diffusion depth of the titanium metal layer on the metal substrate is 50-150 micrometers.
[0009] In the aforementioned UTi-treated cutting tools, the titanium metal layer is composed of one or more of titanium metal oxides, titanium metal nitrides, and titanium metal carbides.
[0010] In the aforementioned UTi-processed cutting tools, the metal base layer is composed of a base metal and a titanium alloy. The metal base layer itself may also be doped with titanium alloy.
[0011] In the aforementioned UTi-processed cutting tool, a pad is fitted on the back of the cutting tool body. The width of the pad is greater than the width of the back of the cutting tool, and the pad is detachably fixed to the cutting tool body.
[0012] The pad at the top of the blade has a wider surface area, which provides a larger force-bearing area. This allows users to apply pressure to the blade with their palm, reducing hand pain. In addition, the connection between the pad and the blade is flexible and detachable, allowing users to install and remove it as needed.
[0013] In the aforementioned UTi-processed cutting tool, the pad strip has an inverted U-shaped cross-section, including a groove extending along the length direction at the bottom. The back of the cutting tool is embedded in the groove. The pad strip has a limiting post extending along the width direction at the end away from the tool holder, and a limiting protrusion extending in the opposite direction along the length at the end near the tool holder. The limiting post passes through the limiting opening on the cutting tool body, and the limiting protrusion extends into the axial insertion hole on the tool holder.
[0014] The pad strip is straight with an upwardly recessed groove at its bottom. The width of this groove is adapted to the thickness of the blade back, allowing the blade back to fit snugly into the groove. The top surface of the blade back is in contact with the inner bottom surface of the groove, reducing relative movement between the pad strip and the blade. At the front end of the pad strip, a limiting post penetrates both the pad strip and the blade along the thickness direction, providing limiting in both the height and length directions. At the rear end of the pad strip, a limiting protrusion inserts axially into the blade holder, providing limiting in the height direction. These two sets of limiting structures together provide limiting in the height direction at both ends of the pad layer, as well as limiting in the length direction of the entire pad layer, ensuring stable installation of the pad strip. Moreover, when removing it, simply remove the limiting post and pull the pad strip a certain distance along its length to remove it.
[0015] In the aforementioned UTi-processed cutting tool, a radially recessed grinding groove is provided circumferentially extending on the outer wall of the middle portion of the limiting post. The cross-section of the grinding groove is V-shaped. The limiting post penetrates the slot. The pad is provided with a limiting post mounting hole that extends through the width direction. The limiting post and the limiting post mounting hole are described above.
[0016] A V-shaped grinding groove is provided in the middle section of the limiting post, which facilitates the grinding of the blade and realizes the multi-functionality of the limiting post. The length of the limiting post is adapted to the thickness of the pad strip, and the two ends of the limiting post are locked in the limiting post mounting holes on both sides of the slot.
[0017] Furthermore, an axial limiting structure is provided between the two ends of the limiting post and the mounting hole of the limiting post. Specifically, as a first feasible solution, the axial limiting structure can be a thread on the outer wall of the limiting post and the wall of the mounting hole of the limiting post; as a second feasible solution, the axial limiting structure can be an annular limiting part set in one of the mounting holes of the limiting post, with an insertion section on one end of the limiting post that is adapted to the inner diameter of the annular limiting part. The front end of the insertion section is provided with a radially extending protrusion, and the annular limiting part is provided with a corresponding slot. After the limiting post is inserted, the protrusion aligns with the slot and passes through. Then, by rotating the limiting post appropriately, the axial limiting with the annular limiting part can be achieved through the protrusion. To facilitate rotation, a slot or protrusion, such as a straight or cross-shaped hole, should be provided on the end face of the limiting post.
[0018] In the aforementioned UTi-processed cutting tool, the limiting opening is a vertically extending rectangle. The width of the limiting opening is adapted to the outer diameter of the limiting post, and the length is greater than the outer diameter of the limiting post. The outer wall of the limiting post abuts against the top surface of the limiting opening. The limiting port has an inwardly protruding bottle-lifting part on one of its length sides; The upper part of the limiting port is located inside the slot, and the lower part protrudes from below the pad strip; The maximum width of the grinding groove is less than the thickness of the blade back.
[0019] The limiting opening is elongated and extends vertically, featuring a multi-functional design. Firstly, the upper part of the limiting opening engages with a limiting post to achieve positioning. Furthermore, the width of the sharpening groove on the limiting post is less than the thickness of the blade back, preventing the blade back from entering the sharpening groove and affecting positioning. Secondly, the lower part of the limiting opening protrudes below the pad strip, allowing for the threading of a rope or hook for attaching the knife. Thirdly, the limiting opening includes a bottle-opening mechanism, enabling the opening of items such as beer bottles after the pad strip is removed.
[0020] In the aforementioned UTi-processed cutting tool, the limiting protrusion is provided on the left and right sides of the end face of the pad strip, and the axial insertion hole is axially opened on one end of the tool holder near the tool body. The limiting protrusion and the axial insertion hole are mutually adapted. The front end of the limiting post is provided with a sheet-like clamp, which can be elastically deformed. Two sheet-like clamps cooperate with each other to form a clip assembly.
[0021] The diameter and position of the limiting protrusion and the axial insertion hole correspond to each other. The limiting protrusion is inserted into the axial insertion hole to achieve axial extension and retraction. In addition, a sheet-like clamp is provided at the front end of the limiting protrusion. The sheet-like clamp can be a thin metal sheet that gradually tapers at the front end. The two sheet-like clamps form a hair clip assembly, which can deform inward and close under the action of external force to achieve functions such as plucking hair or clamping objects. The sheet-like clamp has a tendency to maintain separation due to deformation.
[0022] In the aforementioned UTi-processed cutting tools, the cross-section of the pad strip is a perfect circle or ellipse, or a rectangle with an arc top, or an inverted trapezoid with an arc top, or a D-shape with the arc side facing upwards. The padding strip is made of metal or hard plastic; The top surface of the blade back is provided with a toothed portion, which is located in the groove of the pad strip; And / or, the top surface of the blade back is provided with a cutting part, the cutting part is located in the groove of the pad strip, and the pad strip portion above the cutting part is made of metal.
[0023] The cross-sectional shape of the pad strip varies, but at least the top surface is curved to reduce discomfort to the palm of the hand pressing it. A circular shape is preferred, allowing the pad strip to be removed when needed for tasks such as pounding meat or rolling dough. The pad strip is made of a rigid material to ensure stable installation and provide a consistent palm contact surface. Furthermore, a chopping section or serrated section can be provided on the back of the blade. The serrated section can be used for scraping fish scales or even sawing, while the chopping section uses a thicker blade to chop hard ingredients. Of course, to prevent damage to the pad strip and exposure of the chopping section, the corresponding pad strip portion on the chopping section is made of metal, making it more durable and improving safety.
[0024] Compared with the prior art, the present invention has the following main advantages: 1. The blade body of this tool has a titanium metal layer on the outside of the metal base, which improves the rust and corrosion resistance of the blade body. Moreover, the titanium metal layer is processed onto the metal base through UTi technology. Unlike the coating process, the titanium metal layer is formed by thermal diffusion to form a mutually integrated and mutually penetrating structure, making the titanium metal layer not easy to fall off.
[0025] 2. The pad at the top of the blade back has a wider width, which provides a larger force-bearing area, making it easier for users to apply pressure to the blade back with their palm, reducing hand pain. In addition, the connection between the pad and the blade body is flexible and detachable, allowing users to install and remove it as needed.
[0026] 3. At the front end of the pad strip, a limiting post penetrates both the pad strip and the tool body along the thickness direction, forming a limit in both the height and length directions; at the rear end of the pad strip, a limiting protrusion is axially inserted into the tool holder, forming a limit in the height direction of the pad strip. This ensures stable installation and convenient disassembly of the pad strip.
[0027] 4. A V-shaped sharpening groove is provided in the middle section of the limiting post, which facilitates the sharpening of the blade and realizes the multi-functionality of the limiting post.
[0028] 5. The limiting port is elongated and extends vertically, featuring a multi-functional design. First, the upper part of the limiting port can cooperate with the limiting post to achieve limiting; second, the lower part of the limiting port protrudes below the pad strip, which can be used to thread a rope through a hook for hooking knives; third, the limiting port has a bottle-opening part, which can be used to open items such as beer bottles after removing the pad strip.
[0029] 6. A sheet-like clamp is also provided at the front end of the limiting protrusion. The sheet-like clamp can be a thin metal sheet that gradually narrows at the front end. The two sheet-like clamps form a hair clip assembly, which can deform inward and close under the action of external force to achieve functions such as plucking hair or clamping objects.
[0030] 7. The cross-sectional shape of the pad can vary, but at least the top surface should be curved to reduce discomfort to the palm of the hand pressing it. A circular shape is preferred, as the pad can be removed when needed for pounding meat, rolling dough, etc.
[0031] 8. A chopping section or serrated section can also be provided on the back of the knife. The serrated section can be used to scrape fish scales or even saw cuts, while the chopping section can be used to chop hard ingredients. Of course, in order to prevent the chopping section from being exposed due to damage to the pad, the corresponding pad part on the chopping section is made of metal to improve safety.

Detailed Implementation
[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1
[0035] Specific implementation examples Figures 1-5 As shown, the cutting tool treated with UTi technology includes a cutting body 1 and a shank 2 disposed at one end of the cutting body 1. The cutting body 1 includes a metal base layer 3, which is composed of a base metal and a titanium alloy. Titanium metal layers 4 are provided on both sides of the metal base layer 3. The titanium metal layers 4 are titanium metal oxides. The titanium metal layers 4 are thermally diffused and bonded to the metal base layer 3, with a diffusion depth of 50-150 micrometers.
[0036] Specifically, the cutting tool body 1 has a titanium metal layer 4 outside the metal base layer 3, which improves the rust and corrosion resistance of the cutting tool body 1. Furthermore, this titanium metal layer 4 is processed onto the metal base layer 3 using UTi technology. Specifically, UTi technology involves forming ions from titanium metal at 1000℃ through bias voltage and high current. These ions then diffuse with the metal substrate through thermal diffusion, achieving the effect of the titanium metal layer 4 penetrating into the metal base layer 3. In short, the titanium metal layer 4 and the metal base layer 3 are bonded through thermal diffusion. Unlike coating processes, this thermal diffusion method forms a mutually fused and permeable structure, making the titanium metal layer 4 less prone to detachment.
[0037] like Figure 1 , 2 As shown in Figure 4, a metal pad 6 is fitted onto the back 5 of the blade body 1. The cross-section of the pad 6 is a rectangle with an arc-shaped top. The pad 6 includes a groove 7 extending along the length direction at the bottom. The back 5 is embedded in the groove 7. The pad 6 has a limiting post 8 extending along the width direction at the end away from the handle 2, and a limiting protrusion 9 extending in the opposite direction along the length at the end near the handle 2. The limiting post 8 passes through the limiting opening 10 on the blade body 1, and the limiting protrusion 9 extends into the axial insertion hole 15 on the handle 2.
[0038] Specifically, the pad 6 at the top of the blade back 5 provides a larger force-bearing area, making it easier for the user to apply pressure with their palm, reducing hand pain. The pad 6 is straight, with an upwardly recessed groove 7 at its bottom. The width of the groove 7 is adapted to the thickness of the blade back 5, allowing the blade back 5 to fit snugly into it. The top surface of the blade back 5 is in contact with the inner bottom surface of the groove 7, reducing relative wobbling between the pad 6 and the blade body 1. At the front end of the pad 6, a limiting post 8 penetrates both the pad 6 and the blade body 1 along the thickness direction, forming a limit in both the height and length directions. At the rear end of the pad 6, a limiting protrusion 9 is axially inserted into the handle 2, forming a limit in the height direction of the pad 6. To remove the pad 6, simply remove the limiting post 8 and pull the pad 6 a certain distance along the length direction. The top surface of the blade back 5 has a toothed portion 18, which can be used for scraping fish scales or even sawing. The toothed portion 18 is located inside the pad 6.
[0039] In this embodiment, a radially recessed grinding groove 12 is provided on the circumferentially extended outer wall of the middle part of the limiting post 8. The cross-section of the grinding groove 12 is V-shaped. The limiting post 8 passes through the slot 7. The pad 6 is provided with a limiting post mounting hole 13 that passes through in the width direction. The limiting post 8 and the limiting post mounting hole 13 are provided. An axial limiting structure is also provided between the two ends of the limiting post 8 and the limiting post mounting hole 13.
[0040] Specifically, a V-shaped grinding groove 12 is provided in the middle section of the limiting post 8 to facilitate the grinding of the blade edge of the blade body 1, realizing the multi-functionality of the limiting post 8. The length of the limiting post 8 is adapted to the thickness of the pad strip 6, and both ends of the limiting post 8 are engaged in the limiting post mounting holes 13 on both sides of the slot 7. The axial limiting structure is used to ensure that the limiting post 8 is stable within the limiting post mounting holes 13. The threads on the outer wall of the limiting post 8 and the hole wall of the limiting post mounting hole 13 (not specifically shown in the figure) facilitate rotation. A slotted protrusion 11 is provided on the end face of the limiting post 8.
[0041] like Figure 1 , 2 As shown in Figure 3, the limiting port 10 is a vertically extending rectangle. The width of the limiting port 10 is adapted to the outer diameter of the limiting post 8, and the length is greater than the outer diameter of the limiting post 8. The outer wall of the limiting post 8 abuts against the top surface of the limiting port 10. The limiting port 10 has an inwardly protruding bottle lifting part 14 on one of its length sides. The upper part of the limiting port 10 is located in the slot 7, and the lower part protrudes from below the pad strip 6. The maximum width of the sharpening groove 12 is less than the thickness of the blade back 5.
[0042] Specifically, the limiting opening 10 is elongated and extends vertically, and it has a multi-functional design. First, the upper part of the limiting opening 10 can cooperate with the limiting post 8 to achieve limiting, and the width of the opening of the sharpening groove 12 on the limiting post 8 is smaller than the thickness of the blade back 5, which can prevent the blade back 5 from entering the sharpening groove 12 and affecting the limiting. Second, the lower part of the limiting opening 10 protrudes below the pad strip 6, and this part can be used to thread a rope through the hook for hooking the knife. Third, the limiting opening 10 is provided with a bottle opening part 14, which can be used to open, for example, a beer bottle, after the pad strip 6 is removed.
[0043] like Figure 4 As shown, the limiting protrusion 9 is provided on the left and right sides of the end face of the pad 6, and the axial insertion hole 15 is axially opened on one end of the tool holder 2 near the tool body 1. The limiting protrusion 9 and the axial insertion hole 15 are mutually adapted. The front end of the limiting post 8 is provided with a sheet-like clamp 16. The sheet-like clamp 16 can be elastically deformed. The two sheet-like clamps 16 cooperate with each other to form the hair clip assembly 17.
[0044] Specifically, the diameter and position of the limiting protrusion 9 and the axial insertion hole 15 correspond to each other. The limiting protrusion 9 is inserted into the axial insertion hole 15 to achieve axial extension and retraction. Moreover, a sheet-like clamp 16 is provided at the front end of the limiting protrusion 9. The sheet-like clamp 16 can be a thin metal sheet with a gradually narrowing front end. The two sheet-like clamps 16 form a hair clip assembly 17, which can deform inward and close under external force to achieve functions such as plucking hair and clamping objects. The sheet-like clamp 16 has a deformation tendency to maintain separation.
[0045] Specific working principle: In the fully assembled state, the blade back 5 is equipped with a pad strip 6, which can achieve normal cutting function through the bottom blade. When you need to cut harder ingredients (such as frozen meat), you can press your palm on the pad strip 6 and apply downward force.
[0046] With the pad 6 removed, for example, when opening a beer bottle, the bottle cap can be opened by using the bottle-lifting part 14 on the limiting port 10 to hold the lower edge of the cap and leveraging the principle. Similarly, when plucking feathers, the feather clip assembly 17 can be operated. Operations such as scraping fish scales can be performed using the back of the blade 5 through the serrated part 18 at the top.
[0047] When the blade becomes dull, the limiting post 8 and the pad 6 can be removed. The blade can be sharpened directly through the sharpening groove 12 of the limiting post 8, or the limiting post 8 can be inserted into the pad 6 and the blade can be sharpened by aligning it with the sharpening groove 12 in the slot 7.
[0048] When installing the spacer strip, align the slot 7 with the back of the cutter 5, and initially engage the spacer strip 6 with the cutter body 1. The bottom surface of the slot 7 should be in contact with the back of the cutter 5. Then, push the spacer strip 6 towards the handle 2 until the limiting protrusion 9 is fully inserted into the axial insertion hole 15. After that, install the limiting post 8 into the limiting post mounting hole 13 to complete the installation. To remove the spacer strip 6, simply reverse the operation. Example 2
[0049] The working principle of this embodiment is basically the same as that of embodiment 1, except for the pad 6.
