Abstract
Description
Technical Field
[0001] This utility model relates to electrical appliances, specifically to a food processing device. Background Technology
[0002] Food blenders typically rely on the impact force of high-speed rotating blades to cut food. This method requires water to function and, limited by the blade angle and rotation speed, can easily result in uneven food particles, such as parts being a paste and parts being chunky. Furthermore, there are significant gaps between the blades and the cup walls and bottom, allowing large pieces of food to get stuck, requiring multiple stops and restarts. Therefore, in scenarios such as processing baby food or food for patients with feeding difficulties, blade-cutting blenders are not fine enough to handle the food smoothly. If the processed food contains large particles, it can pose a danger to young infants and other consumers.
[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model discloses a food processing device.
[0005] The technical solution adopted in this embodiment of the utility model is as follows:
[0006] A food processing device includes: a food cup; a rotating shaft rotatable within the food cup, with a helical track provided on the rotating shaft; a grinding disc fixed to the rotating shaft and slidable along the helical track; grinding teeth provided on the lower surface of the grinding disc; the rotation direction of the rotating shaft and the helical direction of the helical track satisfy a vector matching relationship, such that when the rotating shaft rotates, the grinding disc moves downward along the axial component of the velocity of the helical track.
[0007] A further technical solution is that there is a gap between the edge of the grinding disc and the wall of the food cup.
[0008] A further technical solution is that the gap is 1.5~3mm.
[0009] A further technical solution is that a mounting hole for fitting onto the rotating shaft is provided at the center of the grinding disc; a sliding block matching the spiral track is provided in the mounting hole.
[0010] A further technical solution is that there are two spiral tracks; the two sliding blocks are arranged in opposite positions within the mounting hole.
[0011] A further technical solution is that the grinding teeth are arranged in multiple rows; the multiple rows of grinding teeth are arranged radially and uniformly with the center of the grinding disc as the origin.
[0012] A further technical solution is that the inner end of each row of grinding teeth is spaced 1-2 mm away from the mounting hole at the center of the grinding disc.
[0013] A further technical solution is that the material-facing surface of the grinding teeth is perpendicular to the rotation plane of the grinding disc, and the material-facing surface is perpendicular to the tangential direction of the grinding disc.
[0014] A further technical solution is that the width of the material-facing surface of the grinding teeth is 1~2mm and the height is 1~2mm.
[0015] A further technical solution is that the food processing device further includes a main unit, in which a motor and a gear set driven by the motor are installed; a connecting shaft is provided on the food cup; the connector at the upper end of the rotating shaft is connected to the output end of the gear set; and the connector at the lower end of the rotating shaft is installed on the food cup through the connecting shaft.
[0016] The beneficial effects of this utility model embodiment are as follows:
[0017] In this embodiment of the invention, the grinding disc is driven downward by the rotating shaft, which converts the rotational kinetic energy into axial pressure. Through the combined action of squeezing, impact and shearing, the food in the food cup is crushed. During this process, the food is continuously squeezed and impacted, so it can be crushed more uniformly at the microscopic level.
[0018] This invention, by controlling the size of the grinding teeth and the gap, can control the size of the processed food particles, thus ensuring the fineness of the ground food.
[0019] In this embodiment of the invention, no conventional cutting tools are used, and the grinding teeth themselves have no sharp parts, making it less likely for the user to be injured during cleaning and disassembly. Furthermore, the grinding disc and spiral track do not have small, deep gaps, making them easy to clean with water and preventing the formation of hard-to-reach areas. Attached Figure Description

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the device proposed by this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer according to the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, only used to conveniently and clearly assist in illustrating the purpose of the embodiments of this utility model. Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.
[0028] Figure 1 This is an exploded view of the food processing device in an embodiment of this utility model. Figure 2 This is a cross-sectional view of the food processing device in an embodiment of this utility model. Figure 1 , Figure 2 As shown, the food processing device includes a food cup 1, a rotating shaft 2, and a grinding disc 3. The rotating shaft 2 can rotate within the food cup 1. A spiral track 201 is provided on the rotating shaft 2. The grinding disc 3 is fixed to the rotating shaft 2 and can slide along the spiral track 201. Figure 3 This is a schematic diagram of the grinding disc in an embodiment of this utility model. (See diagram below.) Figure 3 As shown, grinding teeth 301 are provided on the lower surface of the grinding disc 3.
[0029] The rotation direction of the rotating shaft 2 satisfies the vector matching relationship with the helical direction of the spiral track 201, so that when the rotating shaft 2 rotates, the grinding disc 3 moves downward along the axial velocity component of the spiral track 201. That is, the grinding disc 3 rotates and moves downward at the same time, grinding the food between the bottom of the grinding disc 3 and the food cup 1.
[0030] The axial direction of the grinding disc 3 is determined by the vector matching relationship between the helix direction of the spiral track 201 and the rotation direction of the rotating shaft 2. The resultant velocity of the grinding disc 3 sliding along the spiral can be decomposed into a tangential component of the velocity around the rotating shaft 2 and an axial component of the velocity for vertical movement. Therefore, the axial component of the velocity of the grinding disc 3 should be downward to meet the cutting requirements, and the tangential component is consistent with the rotation direction of the spiral around the shaft at that point. Therefore, the vector matching relationship can be specifically determined by the chiral rule of the spiral direction and the rotation direction of the rotating shaft 2. For example, when the spiral is right-handed, if the four fingers of the right hand point to the rotation direction of the rotating shaft 2, and the thumb naturally points downward to the food cup 1, then the downward cutting direction of the grinding disc 3 is correct.
[0031] In this embodiment of the invention, the rotating shaft 2 drives the grinding disc 3 to move downwards, converting rotational kinetic energy into axial pressure. Through a combination of squeezing and shearing, the food in the food cup 1 is crushed. During this process, the food is continuously subjected to squeezing and shearing, resulting in more uniform microscopic crushing. Existing technologies use high-speed rotating blades to cut food, but the degree of food crushing is limited by the blade angle and rotation speed, making it more prone to uneven particle formation, with some parts being powder and others lumpy. Therefore, this embodiment of the invention is particularly suitable for scenarios requiring fine grinding of food, such as serving as a baby food cup for preparing complementary foods for infants or patients with difficulty eating.
[0032] Figure 4 yes Figure 2 An enlarged schematic diagram of part A of the structure. (See diagram below.) Figure 4 As shown, furthermore, there is a gap 302 between the edge of the grinding disc 3 and the wall of the food cup 1. Preferably, the gap 302 is 1.5~3mm. The ground food flows out from the gap 302, and then the grinding disc 3 continues to move downwards until all the food is ground. The width of the gap 302 is used to control the size of the food particles after grinding.
[0033] Furthermore, such as Figure 3 As shown, a mounting hole 303 for fitting onto the rotating shaft 2 is provided at the center of the grinding disc 3. A sliding block 304 matching the spiral track 201 is provided within the mounting hole 303. Furthermore, there are two spiral tracks 201. The two sliding blocks 304 are positioned opposite each other within the mounting hole 303, ensuring that the grinding disc 3 rotates stably while moving downwards, preventing uneven force on the food.
[0034] Figure 5 This is a schematic diagram of the grinding disc from another angle in an embodiment of this utility model. (See diagram below.) Figure 3 , Figure 5 As shown, the grinding teeth 301 are arranged in multiple rows, radially and uniformly with the center of the grinding disc 3 as the origin. This radially uniform arrangement of the grinding teeth 301 ensures stability during rotation, preventing unbalanced torque and noise. Preferably, the distance between each row of grinding teeth 301 and the rotation axis at the center of the grinding disc 3 is 1-2 mm. This avoids grinding dead zones and ensures that all ingredients are stably ground.
[0035] Furthermore, the feeding surface 305 of the grinding teeth 301 is perpendicular to the rotation plane of the grinding disc 3, and the feeding surface 305 is perpendicular to the tangential direction of the grinding disc 3. The tangential velocity of the food as the grinding disc 3 rotates forms a 90° angle with the feeding surface 305, and the impact force of the food on the feeding surface 305 is the greatest, which can crush relatively hard food.
[0036] Preferably, the width of the feeding surface 305 of the grinding teeth 301 is 1~2mm, and the height is 1~2mm. The size setting of the grinding teeth 301 can control the size of the ground food particles to be between 1~2mm, resulting in finer food.
[0037] In this embodiment, the food is crushed by the combined impact force of the grinding teeth 301 and the downward squeezing force of the grinding disc 3. The grinding teeth 301 themselves do not have sharp blades, avoiding the risk of cuts during cleaning and disassembly. Moreover, both the spiral track 201 and the structure of the grinding teeth 301 on the grinding disc 3 are mostly smooth surfaces or have only shallow gaps, without small and deep gaps, making them easy to clean with water.
[0038] Furthermore, in combination Figures 1-3 The food processing device also includes a cup lid 4 and a main unit 5. A connector 202 is provided at the upper end of the rotating shaft 2, and a connector is provided at the lower end of the rotating shaft 2. A connecting shaft 101 is provided on the bottom surface of the food cup 1. A motor 6 and a gear set 7 driven by the motor 6 are installed in the main unit 5. The gear set 7 can specifically be a planetary gear or a structure with similar mechanical transmission function.
[0039] When installing the food processing device, the connector at the lower end of the rotating shaft 2 is fitted with the connecting shaft 101, allowing the rotating shaft 2 to rotate around the connecting shaft 101. The cup lid 4 is placed on the food cup 1, exposing the connector 202 at the upper end of the rotating shaft 2. Then, the main unit 5 is installed on the cup lid 4, and the power output end of the gear set 7 is fixed to the connector 202.
[0040] When the motor 6 starts, it drives the gear set 7 to work. The gear set 7 drives the rotating shaft 2 to rotate through the connector 202. The grinding disc 3 moves downward along the spiral track 201 while rotating, grinding the food.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
