Description
Technical Field
[0001] This utility model relates to the field of knife technology, and in particular discloses a vegetable chopping knife for a food processor. Background Technology
[0002] As people's living standards continue to improve, home food processors are becoming increasingly popular in homes and the catering industry, and their ability to efficiently and evenly process ingredients is receiving more and more attention.
[0003] Traditional food processors primarily rely on a single blade for cutting ingredients. While they can achieve basic cutting results during high-speed rotation, they often have unavoidable shortcomings: After ingredients enter the blending cup, the shearing action of the blade is mainly concentrated in a certain area, easily creating "dead zones" on the inner wall of the blending cup. This causes some ingredients adhering to the inner wall to fail to enter the cutting area in time, thus affecting the uniformity and thoroughness of the overall cutting. At the same time, in some designs, the food may remain on the inner wall for a long time, which may lead to local over-chopping during cooking. This results in the final product having overly small particles and a monotonous texture, which contradicts the requirement for the texture of ingredients in many dishes. Utility Model Content
[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a vegetable chopper that ensures that the ingredients are processed fully and evenly during the cutting process.
[0005] To achieve the above objectives, this utility model provides a vegetable chopping blade for a food processor, comprising a blade shaft and a blade assembly mounted on the blade shaft. The blade assembly includes a cleaver and a scraper. The scraper includes a blade body and a bent portion that bends from the blade body, the bent portion engaging with the side wall of the food processor's container. During the rotation of the blade shaft, the cleaver rotates with the blade shaft to cut the food, while the scraper rotates with the blade shaft to scrape off food adhering to the inner side wall of the food processor's container. The cleaver, rotating at high speed, can evenly cut the food, while the scraper is specifically designed to remove food that is easily missed due to adhesion to the inner side wall of the food processor's container. The synergistic effect of both ensures that there are no dead corners when the food enters the mixing zone, thus achieving a comprehensive and uniform processing effect. During operation, the scraper scrapes the food from the inner wall, and under gravity, it naturally falls to the bottom of the food processor's container's side wall. This process avoids over-chopping the food, resulting in larger final food particles with better chewiness and texture. For dishes that require a larger grainy texture, this design better meets the needs of users, ensuring that the dishes are superior in both texture and flavor.
[0006] Furthermore, the scraper is angled relative to the blade shaft, with an angle of 15°-20° between the plane of the scraper and the plane of the blade shaft. This angled arrangement allows the scraper to form a more reasonable contact angle with the inner wall of the food processor's container, thus more effectively scraping off food adhering to the inner wall when the blade shaft rotates at high speed. Simultaneously, this design ensures that most of the inner wall of the food processor's container can be effectively cleaned, preventing food residue from remaining on the inner wall for extended periods and avoiding increased cleaning difficulty.
[0007] Furthermore, the angle between the bent portion and the blade body is 45°-75°. A suitable bending angle can satisfy sufficient mechanical rigidity and ensure that sufficient pressure and friction are generated during rotation, thereby scraping off the adhering food more efficiently. At the same time, a reasonable angle distribution can prevent the scraper from being excessively deformed or broken under force, thus extending its service life.
[0008] Furthermore, the scraper is provided with a first reinforcing rib and a second reinforcing rib protruding from both sides, which are used to enhance the structural strength of the scraper. The reinforcing ribs can disperse and reduce the stress generated during high-speed rotation and friction with the side wall of the food processor container, preventing the scraper from deforming due to uneven force, helping to extend the service life of the overall component, and maintaining stable performance in continuous, high-intensity working environments.
[0009] Furthermore, the cutter is provided in multiple sets, with multiple sets of cutters spaced apart around the cutter shaft and spaced apart along the length of the cutter shaft. The spiral arrangement enables the food to receive continuous and even cutting action when entering the cutting area, avoiding unevenness caused by concentrated cutting. This allows the entire blade assembly to perform multi-directional cutting on the entire food area during operation, thereby improving the uniformity of chopping and the overall processing efficiency.
[0010] Furthermore, along the length of the blade axis, the spacing between the multiple sets of cutting blades is 15-25mm. This spacing ensures sufficient space between the cutting blades for food to smoothly enter the cutting area, while also ensuring the overall stability of the blade assembly structure. It effectively disperses the impact force generated during rotation, reduces the possibility of mutual interference between the cutting blades, and improves overall cutting performance.
[0011] Furthermore, the cutting edge of the blade is 25°-35°. A suitable cutting edge angle can improve its wear resistance and service life while ensuring sufficient cutting sharpness. This angle can ensure strong cutting force and reduce local overheating caused by friction, thus maintaining efficient and uniform cutting of food.
[0012] Furthermore, the cutter shaft includes a main shaft, a pressure sleeve fitted on the main shaft, and a mounting base mounted on the main shaft. The mounting base is connected to an external motor. Multiple sets of pressure sleeves are provided, and a scraper is mounted on one of these sleeves. Multiple sets of cutters and multiple sets of pressure sleeves are alternately mounted on the main shaft. This diversified component integration design ensures that both the cutter and scraper can be installed on the same cutter shaft at predetermined positions and angles, forming a complete working system. The modular design makes the installation, disassembly, and replacement of different components relatively simple, thus facilitating later maintenance and cleaning.
[0013] Furthermore, the spindle has a triangular prism structure, and the pressure sleeve and cutter are provided with mounting holes that are compatible with the spindle. The triangular prism shape effectively prevents the components from deflecting or loosening during spindle rotation, ensuring the overall installation is secure. The compatible mounting holes allow the pressure sleeve and cutter to be firmly fixed on the spindle, improving the mechanical meshing accuracy and working stability during overall transmission.
[0014] Furthermore, the pressure sleeve is provided with a mounting groove for the protruding cutter. The mounting groove design ensures that the cutter can be accurately inserted and kept in a fixed position, and will not shift even during high-speed rotation. This structure helps to simplify the installation process of the overall components, improve assembly efficiency, and is also more convenient for replacement or debugging. The reliably fixed blade can reduce unexpected vibration or loosening during operation, ensuring personnel safety and stable equipment operation during use.
[0015] The beneficial effects of this invention are as follows: the cleaver, rotating at high speed, can evenly cut the ingredients, while the scraper is specifically designed to remove ingredients that are easily missed due to adhesion to the inner and side walls of the food processor's container. The synergistic effect of both ensures that there are no dead corners when ingredients enter the mixing zone, thus achieving a comprehensive and uniform processing effect. During operation, the scraper scrapes the ingredients off the inner wall, and under gravity, they naturally fall to the bottom of the food processor's container. This process avoids over-chopping the ingredients, resulting in larger, more chewy particles with better texture and flavor. For dishes that require retaining a larger particle size, this design better meets the usage needs, ensuring that the dishes are superior in both texture and flavor. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0024] Please see Figures 1 to 5 As shown, this utility model discloses a vegetable chopping blade for a food processor, comprising a blade shaft 1 and a blade assembly 2 mounted on the blade shaft 1. The blade assembly 2 includes a cleaver 3 and a scraper 4. The scraper 4 includes a blade body 5 and a bent portion 6 formed by bending the blade body 5. The bent portion 6 engages with the side wall of the food processor's container. During the rotation of the blade shaft 1, the cleaver 3 rotates with the blade shaft 1 to cut the food, while the scraper 4 rotates with the blade shaft 1 to scrape off food adhering to the inner wall of the food processor's container. The cleaver 3, rotating at high speed, can evenly cut the food, while the scraper 4 is specifically used to remove food that is easily missed due to adhesion to the inner wall of the food processor's container. The synergistic effect of both ensures that there are no dead corners when the food enters the mixing area, thus achieving a comprehensive and uniform processing effect. During operation, the scraper 4 scrapes the food off the inner wall and, under the action of gravity, naturally falls to the bottom of the side wall of the food processor's container. This process avoids over-chopping the ingredients, resulting in larger, more chewy pieces with a better texture and flavor. For dishes that require a larger, more granular texture, this design better meets the needs, ensuring the dish is superior in both texture and flavor.
[0025] The scraper 4 is inclined relative to the blade shaft 1, with an angle of 15°-20° between the plane of the scraper 4 and the plane of the blade shaft 1. This inclined arrangement allows the scraper 4 to form a more reasonable contact angle with the inner wall of the food processor's container, thus more effectively scraping off food adhering to the inner wall when the blade shaft 1 rotates at high speed. Simultaneously, this design ensures that most of the inner wall of the food processor's container can be effectively cleaned, preventing food residue from remaining on the inner wall for extended periods and avoiding increased cleaning difficulty.
[0026] The angle between the bending part 6 and the blade body 5 is 45°-75°. A suitable bending angle can satisfy sufficient mechanical rigidity and ensure that sufficient pressure and friction are generated during rotation, thereby scraping off the adhered food more efficiently. At the same time, a reasonable angle distribution can prevent the scraper 4 from being excessively deformed or broken under force, thus extending its service life.
[0027] The scraper 4 is provided with a first reinforcing rib 7 and a second reinforcing rib 8 protruding from both sides of the scraper 4. The first reinforcing rib 7 and the second reinforcing rib 8 are used to enhance the structural strength of the scraper 4. The reinforcing ribs can disperse and reduce the stress generated during high-speed rotation and friction with the side wall of the food processor container, prevent the scraper 4 from deforming due to uneven force, help extend the service life of the overall component, and maintain stable performance in continuous, high-intensity working environments.
[0028] The cutter 3 is provided in multiple sets, which are spaced apart around the cutter shaft 1 and spaced apart along the length of the cutter shaft 1. The spiral arrangement enables the food to receive continuous and even cutting action when it enters the cutting area, avoiding unevenness caused by concentrated cutting. This allows the entire blade assembly 2 to perform multi-directional cutting on the entire food area during operation, thereby improving the uniformity of chopping and the overall processing efficiency.
[0029] Along the length of the blade shaft 1, the spacing between the multiple sets of cutting blades 3 is 15-25mm. This spacing ensures that there is enough space between the cutting blades 3 so that the food can smoothly enter the cutting area, while also ensuring the stability of the overall structure of the blade assembly 2, effectively dispersing the impact force generated during rotation, reducing the possibility of mutual interference between the cutting blades 3, and improving the overall cutting performance.
[0030] The cutting edge of the blade 3 is 25°-35°. A suitable cutting edge angle can improve its wear resistance and service life while ensuring sufficient cutting sharpness. This angle can ensure strong cutting force and reduce local overheating caused by friction, thus maintaining efficient and uniform cutting of food.
[0031] The cutter shaft 1 includes a main shaft 9, a pressure sleeve 10 sleeved on the main shaft 9, and a mounting base 11 mounted on the main shaft 9. The mounting base 11 is connected to an external motor. Multiple sets of pressure sleeves 10 are provided, and scrapers 4 are mounted on one pressure sleeve 10. Multiple sets of cutters 3 and multiple sets of pressure sleeves 10 are alternately mounted on the main shaft 9. This diversified component integration design ensures that the cutters 3 and scrapers 4 can be installed on the same cutter shaft 1 at predetermined positions and angles, forming an integrated working system. The modular design makes the installation, disassembly, and replacement of different components relatively simple, thus facilitating later maintenance and cleaning.
[0032] Specifically, the scraper 4 is mounted on the lowest layer of the pressure sleeve 10.
[0033] The main shaft 9 has a triangular prism structure, and the pressure sleeve 10 and the cutter 3 are provided with mounting holes that are compatible with the main shaft 9. The triangular prism shape can effectively prevent the components from deflecting or loosening during the rotation of the main shaft 9, ensuring the overall installation is firm. The compatible mounting holes can firmly fix the pressure sleeve 10 and the cutter 3 to the main shaft 9, improving the mechanical meshing accuracy and working stability during the overall transmission.
[0034] The pressure sleeve 10 is provided with a mounting groove 12 for the cutter 3 to pass through. The mounting groove 12 is designed to ensure that the cutter 3 can be accurately inserted and kept in a fixed state, and will not shift even during high-speed rotation. This structure helps to simplify the installation process of the overall components, improve assembly efficiency, and is also more convenient for replacement or debugging. The reliably fixed blade can reduce accidental vibration or loosening during operation, ensuring personnel safety and stable operation of the equipment during use.
[0035] Specifically, the scraper 4 is made of silicone. Silicone is soft but tough, which allows it to make close contact with the inner wall of the mixing cup during high-speed rotation and to deform to a certain extent according to the shape of the cup, ensuring continuous and uniform contact between the scraper 4 and the inner wall. At the same time, silicone itself has the characteristics of being non-toxic, heat-resistant, and corrosion-resistant, which meets the strict requirements of modern food processing for hygiene and safety, ensuring the health and safety of food during processing.
[0036] Specifically, the surfaces of the cutter 3 and scraper 4 are coated with a ceramic coating. This ceramic coating has extremely high hardness and wear resistance, and its covering layer can effectively resist friction and shear wear generated during high-speed rotation, extending the service life of the cutter 3 and scraper 4 and reducing the need for frequent replacement or repair. The ceramic coating surface is smooth and chemically stable, making it difficult to absorb oil or food residue. This characteristic helps prevent food from adhering to the blade surface during cutting and scraping, reducing the accumulation of residue, and facilitating subsequent cleaning and disinfection, further improving hygiene and safety.
[0037] Specifically, a vibration damping pad is provided between the cutter 3 and the pressure sleeve 10, and the damping pad is placed in the mounting groove 12. The damping pad is made of a material with excellent elasticity and wear resistance (such as high-density rubber, silicone, or other engineering plastics), and its main function is to absorb and attenuate the vibration transmitted between the cutter 3 and the pressure sleeve 10. The damping pad is tightly embedded in the mounting groove 12, and through close contact with the cutter 3 and the pressure sleeve 10, it achieves the dispersion and buffering of vibration energy. The damping pad can effectively absorb and attenuate the vibration generated during the high-speed rotation of the cutter, reducing noise. This effect helps to improve the user experience of the product, especially in long-term use or commercial occasions, reducing noise pollution and meeting users' needs for low-noise equipment.
[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
