Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a food processor and its high-efficiency grinding device. Background Technology

[0002] With the improvement of people's living standards and the popularization of healthy eating concepts, food processors (such as soy milk makers, high-speed blenders, and fruit and vegetable blenders) have become common equipment in home kitchens and commercial catering establishments. The core function of these devices is to grind various ingredients (such as beans, grains, nuts, fruits, and vegetables) to meet users' needs for making soy milk, rice paste, fruit and vegetable juices, sauces, and other foods. As the core component of a food processor, the grinding device's grinding efficiency, uniformity, and applicability directly determine the overall performance of the food processor and the user experience.

[0003] Currently, most mainstream food processors on the market employ a single grinding structure, primarily consisting of a stationary grinding head and a moving grinding head. The moving grinding head rotates at high speed around a set axis, working in conjunction with the stationary grinding head to produce a grinding effect, thus pulverizing the materials. However, this single grinding structure has several technical shortcomings in practical applications, making it difficult to meet users' demands for efficient and high-quality pulverization. Specific problems are as follows: Single-grind pulverizing structures rely on the grinding gap between the moving and stationary grinding heads to compress and pulverize materials through friction. When processing large pieces of material (such as whole beans, chunks of fruits and vegetables) or hard materials (such as nuts and hard grains), large pieces are difficult to quickly enter the grinding gap, and hard materials require a long grinding time to reach the desired particle size, resulting in an excessively long overall pulverizing time. For example, when making soy milk using a traditional single-grind soy milk maker, it often takes more than 30 minutes to pulverize soybeans that have not been soaked beforehand or have large particles, and some soybeans are easily left unground, seriously affecting user efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a food processor and its high-efficiency pulverizing device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-efficiency grinding device for a food processor includes a grinding chamber for receiving materials and a grinding assembly for grinding the materials. The grinding assembly includes a stationary grinding head and a moving grinding head, with a grinding area formed between the stationary and moving grinding heads. The high-efficiency grinding device further includes: A crushing blade is fixed to the moving grinding head so as to crush the material by rotating at high speed with the moving grinding head. The crushing blade is configured to drive the material crushed by the blade to flow with the slurry into the grinding area during rotation, thereby improving the grinding efficiency.

[0006] Furthermore, the pulverizing blade includes at least one blade having a set tilt direction configured to drive the slurry to flow outward from the pulverizing blade.

[0007] Furthermore, the grinding zone is located outside the crushing blade, which applies pressure to the slurry during rotation to drive the material into the grinding zone.

[0008] Furthermore, the pulverizing tool includes a first blade, the end of which is bent outward to form a slurry pressing portion, which is disposed above the grinding area to prevent material from leaving the grinding area.

[0009] Furthermore, the slurry pressing section is configured to extend generally in the horizontal direction.

[0010] Furthermore, the moving grinding head includes a fine grinding section and a coarse grinding section, the coarse grinding section being configured to form at least one protrusion above the fine grinding section, and the crushing tool being fixed to the fine grinding section.

[0011] Furthermore, the coarse grinding sections are arranged in two spaced-apart configurations, with a groove formed between the two coarse grinding sections to allow material to flow into the grinding and crushing area, and the crushing blades are fixed to the bottom of the groove.

[0012] Furthermore, the pulverizing device also includes a baffle plate disposed inside the pulverizing chamber and above the stationary grinding head.

[0013] Furthermore, the baffle is fixed to the stationary grinding head, and the crushing blade is staggered from the baffle to form a shearing opening between them for cutting and crushing the material.

[0014] A food processor, characterized in that the food processing device includes the aforementioned high-efficiency grinding device.

[0015] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. This utility model adds a crushing blade fixed to the moving grinding head above the moving grinding head. This blade rotates coaxially with the moving grinding head and can pre-cut and crush the material above the moving grinding head. Compared with the traditional single grinding structure, large or hard materials are pre-treated by the crushing blade, resulting in a significant reduction in particle size. This allows them to quickly enter the grinding area between the moving and stationary grinding heads, avoiding the retention of large materials outside the grinding gap and significantly reducing the workload of the grinding components.

[0016] 2. This utility model adds a baffle plate that is staggered from the crushing blade (axially and / or radially staggered) to form a shearing opening for shearing and crushing. When the crushing blade rotates, it generates high-speed relative motion with the fixed baffle plate, similar to the effect of "scissors shearing", which can efficiently cut materials, especially for hard materials (such as nuts). The shearing force can quickly destroy the material structure and avoid the problems of material slippage and difficulty in crushing in traditional grinding. Attached Figure Description

[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0028] Please see Figures 1-4This utility model discloses a food processor and its high-efficiency grinding device. The high-efficiency grinding device mainly includes a grinding chamber 100 for receiving materials, a grinding component 200 for grinding materials, a grinding blade 400 for cutting and grinding, and a motor 300 for providing power to the device. Among them, the grinding component 200 is the core component for achieving fine grinding of materials, including a stationary grinding head 210 and a moving grinding head 220, forming a grinding area between the stationary grinding head 210 and the moving grinding head 220, in which the materials are further ground and refined; the grinding blade 400 is used for preliminary blade grinding of materials and can drive the ground materials to flow into the grinding area; the motor 300 provides power for the rotation of the moving grinding head 220 and the grinding blade 400, and its rotating shaft 310 is connected to the moving grinding head 220 for transmission, driving the moving grinding head 220 to rotate at high speed around a set axis (i.e., the axis of the rotating shaft 310 of the motor 300), thereby driving the grinding blade 400 fixed on the moving grinding head 220 to rotate synchronously.

[0029] In actual use, the material to be crushed (such as beans, grains, fruits and vegetables) is fed into the crushing chamber 100. After the motor 300 starts, its rotating shaft 310 drives the moving grinding head 220 and the crushing blades 400 to rotate together. The rotating crushing blades 400 first crush the material with their blades, cutting the blocky or granular material into smaller particles or slurry. At the same time, during the rotation of the crushing blades 400, the material slurry formed by the blade crushing is driven to flow into the grinding area, allowing the slurry to enter the grinding area between the stationary grinding head 210 and the moving grinding head 220. Subsequently, the high-speed rotating moving grinding head 220 and the fixed stationary grinding head 210 cooperate to further grind and crush the material slurry that has entered the grinding area, finally obtaining a fine finished material. The entire process realizes a continuous crushing process of "preliminary cutting and crushing - guided grinding - fine grinding", which greatly improves the crushing efficiency and crushing effect of the material. As the space for containing and crushing materials, the structural design of the crushing chamber 100 directly affects the flow of materials and the crushing process. The grinding chamber 100 has a funnel-shaped structure with an open top and a closed bottom. The upper opening is for feeding materials, while the lower end is sealed to the mounting base of the motor 300 to ensure no leakage of the material slurry during grinding. The grinding assembly 200 is a key component for achieving fine grinding of materials, including a stationary grinding head 210 and a moving grinding head 220. The grinding area formed between them is the main site for fine grinding of materials. In this embodiment, the stationary grinding head 210 has an overall annular structure, with its outer diameter matching the inner diameter of the grinding chamber 100. Grinding teeth 211 are provided on the inner ring of the stationary grinding head 210, and these teeth are evenly distributed along the circumference of the stationary grinding head 210. The tooth pitch and tooth height of the grinding teeth 211 can be designed according to the grinding requirements of the material. For materials requiring fine grinding (such as soybeans used to make soy milk), a smaller tooth pitch and lower tooth height can be used to improve the fineness of the grinding; for materials requiring rapid grinding (such as grains used to make rice paste), a larger tooth pitch and higher tooth height can be used to improve grinding efficiency. The moving grinding head 220 is connected to the rotating shaft 310 of the motor 300 and rotates at high speed around a set axis under the drive of the motor 300. The moving grinding head 220 includes a fine grinding section 222 and a coarse grinding section 221. The fine grinding section 222 is located at the lower part of the moving grinding head 220. The coarse grinding section 221 is configured as at least one protrusion formed above the fine grinding section 222. In this embodiment, two coarse grinding sections 221 are arranged at intervals. A groove 800 is formed between the two coarse grinding sections 221 to allow material to flow into the grinding and crushing area. The crushing tool 400 is fixed to the bottom of the groove 800. The outer ring of the fine grinding section 222 is provided with teeth that are adapted to the grinding teeth 211 of the stationary grinding head 210. The teeth 2221 of the fine grinding section 222 mesh with the grinding teeth 211 of the stationary grinding head 210, and the gap formed between them is the grinding area.When the moving grinding head 220 rotates at high speed, the teeth of the fine grinding section 222 and the grinding teeth 211 of the stationary grinding head 210 squeeze, shear, and grind the material slurry entering the grinding area, further refining the particles in the material slurry and achieving fine grinding of the material. During the rotation of the moving grinding head 220, the coarse grinding section 221 can further stir and coarsely grind the material after it has been initially crushed by the crushing blade 400, further breaking down larger particles in the material. At the same time, the groove 800 can guide the material to flow towards the grinding area, ensuring that the material can smoothly enter the grinding area between the fine grinding section 222 and the stationary grinding head 210 for fine grinding. The crushing blade 400 is fixed to the moving grinding head 220 and performs blade crushing of the material as the moving grinding head 220 rotates at high speed, and can drive the material crushed by the blade to flow with the slurry towards the grinding area. The pulverizing cutter 400 includes at least one blade 401 with a predetermined tilting direction configured to drive slurry to flow outward from the pulverizing cutter 400. The grinding zone is located outside the pulverizing cutter 400, and the pulverizing cutter 400 applies pressure to the slurry during rotation, driving the material into the grinding zone. In this embodiment, the pulverizing cutter 400 includes two blades 401, namely a first blade 410 and a second blade 420, which are symmetrically fixed to the bottom of the groove 800 of the moving grinding head 220. In this embodiment, the end of the first blade 410 is bent outward to form a slurry pressing portion 411, which is positioned above the grinding zone and extends generally horizontally. The function of the slurry pressing portion 411 is to prevent the material from leaving the grinding zone, ensuring that the material is fully ground within the grinding zone. Specifically, when the material slurry enters the grinding zone, under the centrifugal force generated by the high-speed rotation of the moving grinding head 220, some of the material slurry may move upward, attempting to leave the grinding zone. The slurry pressing part 411 is located above the grinding area and extends horizontally. It can block and press down the upward-moving slurry material, pushing it back into the grinding area so that the material can continue to be ground. This prevents the material from leaving the grinding area before it is fully ground, improving the thoroughness and efficiency of grinding. In this embodiment, the slurry pressing part 411 and the first blade 410 are integrally formed. The end of the first blade 410 is bent through a stamping process to form the integral structure. This integral structure ensures the connection strength between the slurry pressing part 411 and the first blade 410, preventing the slurry pressing part 411 from falling off during use. At the same time, the lower end face of the slurry pressing part 411 also has a smooth surface treatment to reduce the adhesion of slurry material to its surface and ensure its pressing effect on the material.

[0030] Furthermore, the high-efficiency pulverizing device also includes a baffle 500, which is disposed within the pulverizing chamber 100 and above the moving grinding head 220. The baffle 500 is fixed to the fine grinding section 222, and the pulverizing blade 400 is staggered from the baffle 500 to form a shearing opening 600 between them for cutting and pulverizing the material. In this embodiment, the baffle 500 is generally shaped like a cutting blade. The inner diameter of the baffle 500 is adapted to the outer diameter of the fine grinding section 222 of the moving grinding head 220. In this embodiment, the inner diameter portion of the baffle 500 is provided with a ring of cutting edges, the cross-section of which is triangular, which can enhance the cutting effect of the baffle 500 on the material. The pulverizing blade 400 is staggered from the baffle 500; specifically, the cutting edge of the pulverizing blade 400 is located below or radially inside the baffle 500. When the moving grinding head 220 drives the crushing blades 400 to rotate, the blades of the crushing blades 400 cut the material upwards, while the cutting edge 520 of the baffle 500 cuts the material downwards. The two work together to create a shearing action at the shearing opening 600, which cuts the material into finer pieces, further improving the initial crushing effect. This shearing structure is particularly suitable for processing materials with high fiber content (such as fruits and vegetables), effectively cutting the fibers and preventing crushing difficulties caused by fiber entanglement, thus improving crushing efficiency and quality. Furthermore, the baffle 500 also prevents material splashing. During the high-speed rotation of the crushing blades 400, some material may splash upwards under centrifugal force. The baffle 500, located above the moving grinding head 220, blocks this upward-splashing material, allowing it to fall back into the crushing chamber 100 for further crushing, preventing waste and reducing subsequent cleaning work.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
