Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, specifically to a hand-cranked planer. Background Technology

[0002] In daily life and the catering industry, shredding ingredients such as potatoes, radishes, and pumpkins into shreds is a common operation. The efficiency and effectiveness of this step directly affect the taste and appearance of the subsequent cooking. However, existing shredders on the market have many undeniable shortcomings, causing considerable inconvenience to users.

[0003] First, in terms of food processing range, most traditional graters have limited capacity and can only handle small ingredients. When faced with larger ingredients such as whole pumpkins or large pieces of radishes, users often need to use a knife to cut them into smaller pieces first. This not only adds extra steps and prolongs preparation time, but also poses a safety risk of hand cuts during the cutting process, especially for kitchen novices or those who are not skilled in operating the grater.

[0004] Secondly, regarding material safety, some low-cost graters use inferior plastics or metals that do not meet food contact standards to control costs. These materials may release harmful substances when in contact with food, especially acidic or high-temperature foods, contaminating the food and posing a potential threat to human health. Long-term use of such tools increases food safety risks and does not align with modern consumers' pursuit of a healthy lifestyle.

[0005] Furthermore, existing graters also have significant shortcomings in terms of ease of operation and user experience. Some tools have poorly designed grips with stiff lines, which can easily lead to hand fatigue and soreness after prolonged use, affecting the stability and continuity of operation. At the same time, due to structural design flaws, food is prone to wobbling and shifting during grating, resulting in uneven graters of varying thickness and length, affecting the quality of cooked dishes. In addition, many graters have complex structures with numerous gaps between parts, making it difficult to thoroughly clean residual food scraps after use. This not only affects the tool's lifespan but may also breed bacteria, contaminating new food when reused.

[0006] In addition, while some electric shaving tools have improved efficiency, they rely on a power supply and cannot be used in environments without electricity, such as outdoor picnics or power outages. Furthermore, their structure is relatively complex, resulting in higher maintenance costs, and ordinary users may find it difficult to repair them themselves if they malfunction.

[0007] In summary, existing grating tools have limitations in terms of their ability to handle large ingredients, material safety, ease of operation, cleaning difficulty, and applicable scenarios, failing to adequately meet the diverse needs of users in both everyday cooking and professional food processing. Therefore, developing a new type of grating tool that overcomes these shortcomings is of significant practical importance. Utility Model Content

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figure 1-3As shown, a hand-cranked planer includes a handle 1, one end of which is hinged to a pressure rod 2, and the other end of which is connected to two sets of symmetrically distributed load-bearing bends 5. The two sets of load-bearing bends 5 are hinged to a placement box 7 with openings at the top and bottom. The bottom of the placement box 7 has two sets of symmetrically distributed locking grooves 9 that correspond one-to-one with the two sets of load-bearing bends 5. The top of the corresponding side of the placement box 7 and the pressure rod 2 has an inner groove 8. The bottom of the inner groove 8 has a positioning plate 6 that connects to the side wall of the placement box 7. Between the two sets of load-bearing bends 5, there is a protrusion 4 that connects to the handle 1 and is movably inserted into the positioning plate 6. The end of the pressure rod 2 away from the handle 1 is movably inserted into the inner groove 8 and connected to a pressure plate 3 that is movably inserted into the placement box 7. A shaving tube 10 is rotatably connected between the two sets of load-bearing bends 5 and the two sets of locking grooves 9. The side wall of the shaving tube 10 has multiple sets of evenly distributed cutting holes 12. The shaving tube 10 is connected to a handle 14 that drives it to rotate.

[0029] The handle 1, pressure bar 2, pressure plate 3, protrusion 4, load-bearing bend 5, positioning plate 6, placement box 7, shaving tube 10, and handle 14 are all made of stainless steel. The beneficial effects of this design are: stainless steel has high hardness and strength, ensuring that the components are not easily deformed or damaged during long-term use, thus extending the lifespan of the hand-cranked planer. Simultaneously, stainless steel is safe and non-toxic, and has good corrosion resistance, allowing direct contact with food without chemically contaminating it, thus ensuring food safety and hygiene. Furthermore, the smooth surface of stainless steel does not easily retain food debris, facilitating cleaning and maintenance, effectively reducing bacterial growth, and keeping the tool clean.

[0030] The pressure rod 2 and the pressure plate 3 are forged as a single piece. The advantages of this design are as follows: the one-piece forging process creates a unified structure between the pressure rod 2 and the pressure plate 3, avoiding problems such as weak connections and easy breakage that may occur with welding or other connection methods, significantly enhancing the connection strength and stability between the two. During the pressing of food, it ensures more direct and even pressure transmission, reducing the possibility of pressure plate 3 shaking or failing due to loose connections, thus guaranteeing the pressing effect on the food and improving the stability and uniformity of the shredding. At the same time, the one-piece structure reduces gaps between components, lowering the possibility of food debris residue and facilitating cleaning.

[0031] The pressure plate 3 has an arc-shaped structure. The beneficial effects of this design are as follows: the arc-shaped pressure plate 3 can better conform to the surfaces of ingredients of different shapes and sizes, increasing the contact area with the ingredients and thus applying more uniform and stable pressure. This effectively prevents the ingredients from shaking, shifting, or flipping during the shredding process. This not only ensures the uniformity of the shreds, avoiding uneven thickness and length, but also improves shredding efficiency and reduces repetitive operations caused by ingredient movement. Furthermore, the arc-shaped design better adapts to the contours of the ingredients when pressing, reducing damage caused by excessive localized pressure and protecting the integrity of the ingredients.

[0032] One end of the grater tube 10 is connected to a limiting ring 11, and the other end is connected to a handle 14 via an extended limiting plate 13. The beneficial effects of this configuration are as follows: the limiting ring 11 and the extended limiting plate 13 limit and fix the grater tube 10 from both ends, effectively restricting the axial displacement and radial wobble of the grater tube 10 during rotation, ensuring that the grater tube 10 always maintains the correct working position and stably rotates in cooperation with the bearing bend 5 and the locking groove 9. This avoids poor contact between the grater tube 10 and the food due to positional misalignment, ensuring the continuity and consistency of grating and improving grating quality. Simultaneously, the extended limiting plate 13 connects the handle 14 to the grater tube 10, allowing the force when cranking the handle 14 to be transmitted to the grater tube 10 more smoothly and effectively, reducing energy loss and making operation more effortless and convenient.

[0033] Working principle

[0034] The working principle of this hand-cranked planer is based on the coordinated operation of its various components, as follows:

[0035] First, place the food to be shredded into the placement box 7. The placement box 7 has openings at the top and bottom, which can accommodate large-volume food without pre-cutting. At this time, the handle 1 is hinged to the placement box 7 through two sets of symmetrically distributed load-bearing bends 5 connected to its other end. At the same time, the protrusion 4 on the handle 1 is movably inserted into the positioning plate 6 at the bottom of the groove 8 inside the placement box 7, which serves to position and stabilize the placement box 7, ensuring that the placement box 7 will not easily shake during subsequent operations.

[0036] Next, grasp the handle 1 and press down on the pressure rod 2 through the hinged connection between the pressure rod 2 and the handle 1. The end of the pressure rod 2 away from the handle 1 will movably engage with the inner groove 8, causing the pressure plate 3 connected to it to move downward within the placement box 7. Because the pressure plate 3 has an arc-shaped structure, it can better conform to the surface of the food, providing stable pressure and preventing the food from shifting during the shredding process, thus ensuring the uniformity of the shreds.

[0037] Then, crank the handle 14, which drives the shaving tube 10 to rotate via the extended limiting plate 13. The shaving tube 10 is rotatably connected between the two sets of bearing bends 5 and the two sets of snap-fit ​​grooves 9. The limiting ring 11 at one end and the extended limiting plate 13 at the other end work together to limit the rotation of the shaving tube 10, ensuring that the shaving tube 10 remains stable during rotation and preventing deviation from affecting the shaving effect.

[0038] When the shredder tube 10 rotates, multiple sets of evenly distributed blade holes 12 on its side wall come into contact with the food fixed by the pressure plate 3. The food is shredded into shreds by the cutting action of the blade holes 12, and the shredded shreds are discharged through the blade holes 12, thus completing the shredding process of the food.

[0039] Example 1

[0040] Everyday use scenarios in a family kitchen

[0041] In a home kitchen, a user prepares to make stir-fried shredded potatoes with vinegar. First, a medium-sized potato is taken from the refrigerator and placed in the holder 7 of the hand-cranked grater. Since the holder 7 is open at the top and bottom and has ample space, pre-cutting the potato is unnecessary. Next, the user holds the handle 1 and presses down the pressure bar 2. The pressure bar 2 moves the one-piece forged arc-shaped pressure plate 3 downwards, tightly fitting against the potato surface and applying stable pressure to prevent the potato from shaking during grating. Then, the user starts cranking the handle 14. The handle 14, through the extended limiting plate 13, rotates the grating tube 10. The evenly distributed cutting holes 12 on the grating tube 10 cut the potato, and shredded potatoes are continuously discharged from the cutting holes 12. Throughout the process, because all parts are made of stainless steel, not only is the tool's durability ensured, but the shredded potatoes are also protected from material contamination. After grating, the user simply rinses the hand-cranked grater under running water. Because the stainless steel surface is smooth and the parts have few gaps, any remaining potato scraps are easily washed away, making cleaning very convenient.

[0042] Example 2

[0043] Application scenarios of small catering establishments

[0044] In a small Chinese restaurant, the chef needs to prepare a large quantity of shredded radish for making radish cake. The chef places several whole white radishes into the holder 7 of the hand-cranked grater. Thanks to the holder 7's design, which can hold larger ingredients, there's no need to spend time cutting the radishes into small pieces. The chef holds the handle 1 with both hands and repeatedly presses down the pressure bar 2, using the curved pressure plate 3 to stably press the white radish. Then, the chef quickly cranks the handle 14, causing the grater tube 10 to rotate at high speed, efficiently grating the white radish into uniform shreds. Because the pressure bar 2 and pressure plate 3 are forged as a single piece, the structure remains sturdy and stable during frequent pressing, preventing loosening that could affect the pressing effect. The limiting ring 11 and the extended limiting plate 13 ensure that the grater tube 10 remains stable even at high speed, resulting in radish shreds of uniform thickness. Furthermore, the stainless steel components can withstand frequent use and are not easily damaged, meeting the high-intensity usage requirements of a catering establishment. After use, restaurant staff can quickly disassemble and clean the hand-cranked peeler. The smooth surfaces of each part make cleaning easy, effectively saving cleaning time and preparing for subsequent cooking.

[0045] Example 3

[0046] Outdoor picnic scene

[0047] A group of friends are having a picnic outdoors and are preparing to make cucumber salad. One of them takes out a hand-cranked cucumber peeler and places a fresh cucumber into the container 7. In the absence of complex kitchen equipment outdoors, the portability and ease of use of the hand-cranked peeler become apparent. The user holds the handle 1 with one hand and presses down the pressure bar 2 with the other, fixing the cucumber in place with the curved pressure plate 3. Then, by cranking the handle 14, the cucumber is easily shredded. The entire process is simple and convenient, and even those without kitchen experience can quickly get the hang of it. Since the hand-cranked peeler requires no electricity and is not limited by the outdoor environment, it has a clear advantage in picnic settings. Moreover, its material is safe and non-toxic, and will not contaminate the food due to outdoor environmental factors. After shredding, a simple rinse with water is sufficient; the stainless steel parts are rust-resistant, making it convenient for future outdoor use and adding to the convenience of the picnic.
