Flow blocking mechanism and food processor thereof

Abstract

This application discloses a flow-blocking mechanism, a food processing component, and a food processor thereof. The flow-blocking mechanism includes a first fixed frame and blades. The blades are connected to the first fixed frame and have at least a first flow-blocking surface for blocking fluid rotating around the axis of the blender. The blades are impacted by the fluid, hindering its rotation and reducing its flow velocity. Simultaneously, the blades also rotate with the fluid due to the impact. The flow-blocking mechanism of this food processor works in conjunction with the grinding blades. When the blades rotate, the fluid is driven to rotate. Upon encountering the flow-blocking mechanism, the fluid velocity decreases, increasing the relative speed between the fluid and the blades, thereby increasing the contact frequency and effectively improving the grinding effect at lower grinding speeds.

Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a flow-blocking mechanism, a food preparation component, and a food processor thereof. Background Technology

[0002] Most mainstream food processors (such as high-speed blenders) currently use blades for grinding, which typically requires high speeds to achieve good grinding performance. During operation, the high-speed rotation of the blades generates noise from cavitation, agitation, and vortex processes, generally exceeding 75dB. This significantly impacts people's comfort and health. Food processors that use other grinding methods to reduce noise suffer from low processing efficiency. Summary of the Invention

[0003] The main technical problem addressed by this application is to provide a flow-blocking mechanism, a food processing component, and a food processor that have high processing efficiency and low noise.

[0004] To solve the above-mentioned technical problems, the present application adopts a technical solution as follows: a flow-blocking mechanism for a food processor, including a first fixed frame; blades connected to the first fixed frame and having at least a first flow-blocking surface for blocking fluid rotating around the axis of the blender, while being driven to rotate with the fluid by the impact of the fluid.

[0005] The first fixed frame includes a ring plate with a through hole, which is sleeved on the rotating shaft of the stirrer and can rotate relative to the rotating shaft. The number of blades is several, with one end connected to the ring plate as the center and the other end extending radially away from the center.

[0006] The blade includes a first blade portion and a second blade portion. One end of the second blade portion is connected to a first fixing frame, and the other end is connected to one end of the first blade portion. A first flow-blocking surface is disposed on the first blade portion, and the second blade portion has a second flow-blocking surface.

[0007] The first flow-blocking surface is perpendicular to or inclined at a first angle to the axial section of the rotation axis, and the second flow-blocking surface is parallel to or inclined at a second angle to the axial section, with the second angle being smaller than the first angle.

[0008] The second flow-blocking surface is smoothly connected to the first flow-blocking surface.

[0009] The flow-blocking mechanism may further include a second fixing frame, which is connected to the first blade portion of each of the at least two blades.

[0010] Among them, the blade extends radially outward from the first fixed frame and then bends to extend axially.

[0011] Both the second and first fixed frames are annular and coaxially arranged. The diameter of the second fixed frame is larger than that of the first fixed frame, and the blade is located in the space between the second and first fixed frames.

[0012] The second blade is connected to the first fixing frame at one end and extends outward by a first distance at a first angle. The other end of the second blade is connected to the third blade, which extends outward by a second distance at an angle substantially parallel to the rotation axis section.

[0013] The third blade is connected to the first blade at the other end, and the angle between the third blade and the first blade is between 20 degrees and 160 degrees.

[0014] The blade includes a first blade section, a second blade section and a third blade section. One end of the second blade section is connected to a first fixing frame, and the other end is connected to one end of the third blade section. The other end of the third blade section is connected to one end of the first blade section. A first flow-blocking surface is provided on the first blade section, the second blade section has a second flow-blocking surface, and the third blade section has a third flow-blocking surface.

[0015] The first flow-blocking surface extends axially, is inclined to the axial direction, or is inclined to the rotation axis. The third flow-blocking surface is located in the rear section of the third blade portion facing the stirrer blade in the rotation direction, and gradually bends towards the blade along the rotation direction.

[0016] The first flow-blocking surface gradually approaches the rotation axis in the rotation direction until a portion of it connects with the third flow-blocking surface, and a guide groove is formed at the connection point that gradually approaches the rotation axis and the blade in the rotation direction.

[0017] The distance between the third flow-blocking surface and the blade on the side of the rotation direction varies from gradually increasing to gradually decreasing in the direction away from the rotation axis.

[0018] Among them, the front section of the third blade facing the stirrer blade is parallel to the axial section in the direction of rotation, forming a stable flow surface that connects to the third flow-blocking surface.

[0019] The angle between the third flow-blocking surface and the first flow-blocking surface is between 20 degrees and 160 degrees.

[0020] The angle between the third flow-blocking surface and the first flow-blocking surface is between 80 and 100 degrees.

[0021] The distance between the second flow-blocking surface and the blade gradually increases in the direction away from the rotation axis and gradually decreases in the direction along the rotation direction; the third flow-blocking surface is located in the rear section of the third blade facing the stirrer blade in the rotation direction and gradually bends towards the blade along the rotation direction.

[0022] The angle between the third flow-blocking surface and the second flow-blocking surface is between 40 degrees and 140 degrees.

[0023] Another technical solution adopted in this application is: providing a cooking component, including a mixer; a first fixed frame that can rotate around the axis of the mixer; and blades connected to the first fixed frame and having at least a first flow-blocking surface for blocking fluid rotating around the axis of the mixer, while being driven to rotate with the fluid by the impact of the fluid.

[0024] The agitator includes blades that are at least partially inclined to the axial section of the agitator's rotation axis, and a first flow-blocking surface is configured to block at least a portion of the fluid from entering the rotation path of the blades.

[0025] The blade includes a first blade portion and a second blade portion. One end of the second blade portion is connected to a first fixing frame, and the other end is connected to one end of the first blade portion. A first flow-blocking surface is provided on the first blade portion, and the second blade portion has a second flow-blocking surface. The second flow-blocking surface is inclined to the axial section of the rotating shaft of the stirrer, the inclination angle between the second blade portion and the rotating shaft is less than 90 degrees, and the width of the blade is between 3mm and 20mm.

[0026] The axial distance between the second blade and the blade ranges from 1mm to 15mm.

[0027] The blade is located on the upper side of the second blade portion and inside the first blade portion. Another technical solution adopted in this application is: providing a food processor, including a food processor assembly; a cup body for containing fluid; the food processor assembly located within the cup body; and a motor for driving the stirrer to rotate.

[0028] The blades are located between the stirrer and the bottom of the cup, with a distance of 0.5-3mm between the blades and the bottom of the cup, and a distance of 0.5-2mm between the blades and the side wall of the cup.

[0029] The beneficial effects of this application are as follows: Unlike the prior art, the embodiments of this application, through the cooperation of the blade and the flow-blocking mechanism, enable the flow velocity of the fluid to be relatively reduced by the flow-blocking mechanism when the blade is grinding the fluid. That is, while the blade speed remains constant, the relative speed between the blade and the fluid is increased, thereby increasing the contact frequency between the fluid and the blade and improving the grinding efficiency. On the other hand, the flow-blocking mechanism guides part of the fluid to the blade, so that the blade can repeatedly grind the fluid, thus eliminating the need for a high blade speed. Ultimately, this achieves higher processing efficiency and lower noise, improves the taste of beverages, and enhances the user experience. Attached Figure Description

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0047] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0048] To better understand this application, the following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed description of a flow-blocking mechanism, a food processing component, and a food processor provided in this application.

[0049] Please refer to the following: Figures 1 to 5 . Figure 1 This is a schematic diagram of the structure of the first embodiment of the flow-blocking mechanism of this application. In this first specific embodiment, the flow-blocking mechanism includes a first fixed frame 10 and a blade 20. The blade 20 is connected to the first fixed frame 10 and has at least a first flow-blocking surface 210, which blocks the fluid rotating around the axis of the stirrer 40. At the same time, the blade 20 is driven to rotate with the fluid under the impact of the fluid. The specific application scenario of the flow-blocking mechanism can be a food processor in the home appliance field, such as a high-speed blender, coffee machine, juicer, blender, etc. Taking a high-speed blender as an example, when using a high-speed blender, people generally choose to put a certain proportion of water and ingredients into the cup 50 of the blender together (see...). Figure 10Then, the blender is rotated, and the blades 41 of the blender rotate to grind the ingredients. After the ingredients are ground, some will dissolve in the water, and the rest will be fine particles that are difficult to dissolve in water. At this time, there is a mixture of liquid and fine particles in the blender. This mixture is referred to as fluid in this application for further explanation. The first fixing frame 10 in the flow-blocking mechanism is used to rotatably engage the flow-blocking mechanism with the rotating shaft 42, and can also connect and fix the blades 20 so that the blades 20 can be set around the rotating shaft 42 by the first fixing frame 10. The specific shape of the blades 20 can be various, but it needs to have at least one flow-blocking surface, that is, the first flow-blocking surface 210 mentioned in this application. The first flow-blocking surface 210 is used to block the fluid rotating around the axis of the blender 40 to reduce the flow rate of the fluid. Of course, while reducing the fluid rotation speed, the flow-blocking mechanism is also designed to be able to be driven by the fluid impact to rotate the blades 20 with the fluid. Therefore, the flow-blocking mechanism will absorb the momentum of the fluid and rotate.

[0050] Because the blade 20 can rotate with the fluid, its rotational speed is lower than that of the blade. However, in some embodiments, the blade 20 can be driven to rotate by a drive mechanism, thereby changing the natural rotational speed of the blade 20 while it blocks the fluid. In more embodiments, the coefficient of friction between the first fixed frame 10 and the rotating shaft 42 can be designed to adjust the natural rotational speed of the blade 20. The blade 20 and the first fixed frame 10 can be connected in a fixed, sliding, or detachable manner, or they can be integrally molded in the actual production process to reduce costs. The first fixed frame 10 can also be fixed to the end of the blade 20 instead of rotating with the rotating shaft 42, serving to fix the blade 20.

[0051] The first fixing frame 10 includes a ring plate 11 with a through hole 12. The ring plate 11 is fitted onto the rotating shaft 42 of the stirrer 40 through the through hole 12, allowing the first fixing frame 10 to rotate relative to the rotating shaft 42. Various fitting methods can be used. For example, the diameter of the through hole 12 can be set larger than the diameter of the rotating shaft 42, allowing for a clearance fit. Alternatively, a bearing can be placed in the through hole 12 of the ring plate 11, with its outer ring fixedly connected to the ring plate 11 before being fitted onto the rotating shaft 42, allowing the ring plate 11 to rotate smoothly around the rotating shaft 42. Of course, various other methods exist, as long as the first fixing frame 10 can rotate relative to the rotating shaft 42.

[0052] Furthermore, it is preferable to have several blades 20 on the flow-blocking mechanism. For example, there could be two blades 20, designed as symmetrical blades 20, or three blades 20, four blades 20, etc. Multiple blades 20 can be arranged around the annular plate 11, with one end of the blade 20 connected to the annular plate 11 and the other end extending radially away from the center. Multiple blades 20 can have the same structure or different structures and sizes. When multiple blades 20 are distributed around the annular plate 11 at equal or unequal angles, it can reduce the uneven force distribution in various directions when the blades 20 are impacted by the fluid, thereby preventing deformation of the blades 20 or the first fixing frame 10.

[0053] Please continue reading. Figure 1 In this embodiment, the blade 20 can be further divided into a first blade portion 21 and a second blade portion 22. One end of the second blade portion 22 is connected to the first fixing frame 10, and the other end extends radially outward away from the rotation axis 42, connecting to one end of the first blade portion 21. The first blade portion 21 extends further after connecting to the second blade portion 22, but its direction of extension may be the same as or different from that of the second blade portion 22, as will be described in more detail below. A first flow-blocking surface 210 is formed in the first blade portion 21, and a second flow-blocking surface 220 is formed in the second blade portion 22. Both the first flow-blocking surface 210 and the second flow-blocking surface 220 can functionally impede fluid rotation. Optionally, the first flow-blocking surface 210 can be set as the primary flow-blocking surface to mainly block fluid rotation, while the second flow-blocking surface 220 has more of a guiding function, enabling the fluid to be guided to the first flow-blocking surface 210 or the blade to achieve a faster reduction in fluid rotation speed.

[0054] Alternatively, the first flow-blocking surface 210 can be configured to be perpendicular to or inclined at a first angle to the cross-section of the rotation shaft 42, while the second flow-blocking surface 220 can be configured to be parallel to or inclined at a second angle to the cross-section, with the second angle being smaller than the first angle. For example, the second blade portion 22 can first extend horizontally outward from the first fixing frame 10, and then at the end of the second blade portion 22, extend upward at an angle perpendicular to the second blade portion 22 to form a first blade portion 21, which can be used to block water flow. Alternatively, the second blade portion 22 can first be connected to the first fixing frame 10 and then extend outward in a spiral twist to form a second angle with the cross-section of the rotation shaft 42, such as 10 degrees, 15 degrees, 35 degrees, etc., and its specific parameters can be designed according to the specific application scenario. At the end of the second blade portion 22, the first blade portion 21 continues to extend, so that the first blade portion 21 forms a first angle with the cross-section, such as 90 degrees, 80 degrees, etc., and the specific angle can be designed in conjunction with the product.

[0055] Please continue to refer to the following: Figure 1 and Figure 2 .in Figure 2 This is yet another embodiment provided in this application. In this embodiment, the second flow-blocking surface 220 of the flow-blocking mechanism is smoothly connected to the first flow-blocking surface 210. That is, the second blade portion 22 where the second flow-blocking surface 220 is located and the first blade portion 21 where the first flow-blocking surface 210 is located are connected in a smooth arc shape, so as to facilitate integral processing and at the same time, it can prevent the fluid from flowing more evenly and smoothly on the blade 20, and avoid additional noise caused by abrupt changes in the angle design of the blade 20.

[0056] To further improve the structural stability of the flow-blocking mechanism under the impact of water flow, this application provides a flow-blocking mechanism with a second fixing frame 30. The second fixing frame 30 is connected to the first blade portion 21 of each of at least two blades 20, thereby enhancing the stability between the first blades 20 through connection. Optionally, the first blade portions 21 of each blade 20 can be connected sequentially using a ring plate 11 to form a fixed ring centered on the rotation axis 42. In addition to reinforcing the structure of the blades 20, the second fixing frame 30 can also have a certain function of concentrating the water flow. When the blade 41 rotates at high speed, causing the fluid to rotate, the fluid flows downward and outward due to the compression of the blade 41. At this time, if the ring plate 11 of the second fixing frame 30 is designed to be a wider ring plate 11, it can block the outward flow of the fluid to a certain extent, thus having a certain concentrating effect.

[0057] In another embodiment, the blades 20 of the flow-blocking mechanism extend radially outward from the first fixing frame 10 and then bend to extend axially, which will not be described in detail here.

[0058] Optionally, both the second fixing frame 30 and the first fixing frame 10 of the flow-blocking mechanism can be annular, and they are coaxially arranged with the rotation axis 42 as the center. Specifically, the diameter of the second fixing frame 30 can be larger than the diameter of the first fixing frame 10, and one end of the blade 20 is connected to the first fixing frame 10, and the other end is connected to the second fixing frame 30. The blade 20 is configured to have at least a portion located in the gap space between the second fixing frame 30 and the first fixing frame 10, so that the slurry is blocked by the blade 20 in the gap space and ultimately flows in the gap space at a lower flow rate.

[0059] Please see Figure 3 , Figure 4 and Figure 5 . Figure 3 This is a structural diagram of an existing blender mixer 40. Figure 4 This is a schematic diagram of the structure of the stirrer 40 and the flow obstruction mechanism in this application. Figure 4 and Figure 5 This application Figure 1 and Figure 2A schematic diagram of the structure of the flow-blocking mechanism in conjunction with the stirrer 40. (See attached diagram.) Figure 3 As shown, existing blenders only have blades 41 for grinding food. In the prior art, there are two common methods to improve the cutting and grinding effect of the blades 41. First, by setting the blades 41 to a multi-layered structure, for example... Figure 3 The three-layer blade 41 includes an upper blade 410, a middle blade 411, and a lower blade 412, thereby increasing the contact area between the blades and the fluid. Secondly, the grinding effect is improved by continuously increasing the rotation speed of the blades 41 during food processing. Neither of these methods is optimal in terms of blade cost or noise.

[0060] This application provides a cooking assembly including a mixer 40, a first mounting bracket 10, and blades 20. The first mounting bracket 10 is rotatable around the axis of the mixer 40, and the blades 20 are connected to the first mounting bracket 10. The blades 20 have at least a first flow-blocking surface 210, which blocks fluid rotating around the axis of the mixer 40. According to Newton's third law, while the blades 20 block the fluid rotation through the first flow-blocking surface 210, they also receive the impact force of the fluid, and are thus driven to rotate around the rotation axis 42. In one embodiment, the mixer 40 of the cooking assembly includes blades 41. The blades 41 in this application can consist only of a central blade 411 and a flow-blocking mechanism for grinding, achieving a better grinding effect and significantly improving economic efficiency. Specifically, at least a portion of the blade 411 is inclined to the axial section of the rotating shaft 42 of the stirrer 40. The first flow-blocking surface 210 is configured to allow at least a portion of the blocked fluid to enter the rotation path of the blade 411, so that the fluid, after being blocked and slowed down, can contact the blade 411 at a higher relative rotational speed, increasing the contact frequency with the blade 411, which is beneficial to improving the grinding effect and effectively reducing noise. Further, the blade 20 includes a first blade portion 21 and a second blade portion 22. One end of the second blade portion 22 is connected to the first fixing frame 10, and the other end is connected to one end of the first blade portion 21. The first blade portion 21 is provided with a first flow-blocking surface 210 for hindering fluid rotation. The second blade portion 22 is provided with a second flow-blocking surface 220 for hindering fluid rotation. The specific shapes of the first flow-blocking surface 210 and the second flow-blocking surface 220 are determined by the shapes of the first blade portion 21 and the second blade portion 22. For example, when the first blade portion 21 is in the form of a twisted spiral, the first flow-blocking surface 210 on its outer surface can be understood as a twisted spiral curved surface. Similarly, if the second blade portion 22 is a rectangular flat sheet, then the second flow-blocking surface 220 is a normal flat surface. When the blade 41 cooperates with the rotating shaft 42, it has a certain angle of inclination to have a stronger pushing force to squeeze the fluid downwards, for example, refer to Figure 5The blade 41 has an inclined angle relative to the cross section of the rotating shaft 42. In order to ensure that the second flow-blocking surface 220 has a certain flow-guiding function, the second flow-blocking surface 220 may optionally be inclined to the axial section of the rotating shaft 42 of the stirrer 40.

[0061] Furthermore, to improve grinding efficiency while effectively ensuring low noise, this application provides the following specific implementation method. The inclination angle between the second blade portion 22 and the axis of rotation 42 can be set to less than 90 degrees, and the width of the blade 20 can be set between 3mm and 20mm. A certain axial distance should be maintained between the blade 20 and the blade 41 to prevent large food particles from getting stuck between them and affecting the normal operation of the machine; for example, the spacing can be between 1mm and 15mm. Regarding the number of blades 20, 2 to 10 blades can be selected, preferably 3. To ensure a better flow obstruction effect, the distance between the edge of the blade 41 and the edge of the blade 20 is 1mm-10mm, and the gap between the bottom edge of the blade 41 and the top edge of the second fixing frame 30 is 15mm-60mm. The width of the second fixing frame 30 can be a ring less than 50mm. Simultaneously, to consider the structural stability of the blade 20 and the second fixing frame 30, both should also have a certain thickness, for example, between 0.4mm and 3mm. The specific dimensions can be limited according to the specific product application scenario and are not specifically restricted here.

[0062] Please see Figure 6 This is a schematic diagram of another embodiment of the present application. In this embodiment, the second blade portion 22 can be configured to extend in a direction parallel or substantially parallel to the cross-section of the rotation axis 42 to form a radial second blade portion 22. In this embodiment, there are three mating second blade portions 22. Correspondingly, at the end of the second blade portion 22, a first blade portion 21 extends upward in a direction perpendicular or approximately perpendicular to the second blade portion 22. At the end of the first blade portion 21, a second fixing frame 30 is connected between adjacent first blade portions 21. In this embodiment, the second fixing frame 30 can be in a ring shape, or of course, other fixing frame shapes.

[0063] Please see Figure 7 and Figure 8 This is a schematic diagram of the structure of another embodiment provided in this application.

[0064] In this flow-blocking mechanism, one end of the second blade portion 22 is connected to the first fixing bracket 10 and extends outward by a first distance at a first angle. During the extension of the first distance, it can be an arc-shaped bend or a straight extension. This first distance can be specifically designed according to the size of the cup body 50, for example, it can extend by 5mm, 15mm, etc., without specific limitations. The first angle can be upward or downward, forming a certain angle with the cross-section of the rotation axis 42, for example, it can be 8 degrees to 35 degrees. Of course, it can also be designed according to actual conditions. At the other end of the second blade portion 22, a third blade portion 23 is connected, and the third blade portion 23 extends outward by a second distance at an angle substantially parallel to the cross-section of the rotation axis 42. Optionally, the second blade portion 22 extends downward by the first distance and continues to extend parallel to the cross-section of the rotation axis 42 at its end to form the third blade portion 23.

[0065] To better achieve the flow obstruction effect, the flow obstruction mechanism also includes a first blade portion 21. The other end of the third blade portion 23 is connected to the first blade portion 21, and the angle between the third blade portion 23 and the first blade portion 21 is between 20 and 160 degrees. Optionally, the extension angle of the second blade portion 22 is downward, and the extension direction of the first blade portion 21 is upward, so that the blade 41 used in conjunction with it is positioned above the multiple second blade portions 22 and inside the multiple first blade portions 21. This design is more conducive to the cooperation between the first blade portion 21, the second blade portion 22, and the third blade portion 23, reducing the rotational speed of the fluid flowing due to the blade 41. While the rotational speed of the blade 41 remains constant following the rotational shaft 42, the relative rotational speed between the fluid and the blade 41 is relatively increased, ultimately improving the grinding effect.

[0066] Please see Figures 9 to 12 All of these include a flow-blocking mechanism provided in this embodiment. In this embodiment, the flow-blocking mechanism blade 20 includes a first blade portion 21, a second blade portion 22, and a third blade portion 23. One end of the second blade portion 22 is connected to the first fixing frame 10, and the other end is connected to one end of the third blade portion 23. The other end of the third blade portion 23 is connected to one end of the first blade portion 21. A first flow-blocking surface 210 is disposed on the first blade portion 21, the second blade portion 22 has a second flow-blocking surface 220, and the third blade portion 23 also has a third flow-blocking surface 230. In one embodiment, the first flow-blocking surface 210 can extend axially, that is, it can extend in a direction parallel to the rotation axis. The first flow-blocking surface 210 can also extend inclined to the axial section or inclined to the rotation axis, so that the inclined flow-blocking surface can, on the one hand, block the rotation of the fluid, and on the other hand, play a certain guiding role, guiding the fluid to the blade 41 above the flow-blocking mechanism. Figure 9 , Figure 10 , Figure 11 and Figure 12The position of the blade 41 is not shown in the figures. The positional relationship between the blade 41 and the flow-blocking mechanism in this embodiment can be referred to... Figure 5 The third flow-blocking surface 230 is located at the rear end of the third blade portion 23 facing the stirrer blade 41 in the rotational direction, and gradually curves towards the blade 41 along the rotational direction. In one embodiment, the first flow-blocking surface 210 gradually approaches the rotational axis in the rotational direction until a portion connects with the third flow-blocking surface 230, and a guide groove is formed at the connection point that gradually approaches the rotational axis and the blade 41 along the rotational direction. This guide groove has a certain degree of torsional curvature, so it can guide the fluid to the blade 41 above the flow-blocking mechanism while blocking the flow, thereby increasing the contact frequency between the blade 41 and the fluid.

[0067] In one embodiment, the distance between the third flow-blocking surface 230 and the blade 41 on the side of the rotation direction gradually increases in the direction away from the rotation axis. For details, please refer to [reference needed]. Figure 10 , Figure 11 and Figure 12 . Figure 10 In the middle, the cut surface of the flow-blocking mechanism is located 5mm behind the middle cross-section of blade 20. Figure 11 The cut surface is located in the cross section in the middle of the blade 20. Figure 12 The cut surface is located 5mm backward and forward of the blade 20. Because the distance between the side of the third flow-blocking surface 230 on the side of the rotation direction and the blade 41 gradually increases in the direction away from the rotation axis, the bottom of the third flow-blocking surface 230 and the bottom of the cup body 50 are at the same distance. Figure 10 The distance B in the middle is relatively large, Figure 11 Smaller in the middle Figure 12 The distance in the view is the smallest among the three views. In another embodiment, the third flow-blocking surface 230 may gradually increase and then decrease in the direction away from the rotation axis.

[0068] In one embodiment, the leading edge of the third blade portion 23 facing the stirrer blade 41 in the direction of rotation is parallel to the axial section, forming a flow-stabilizing surface connecting the third flow-blocking surface 230. The angle between the third flow-blocking surface 230 and the first flow-blocking surface 210 can be set between 20 degrees and 160 degrees. The angle between the third flow-blocking surface 230 and the first flow-blocking surface 210 can be set between 80 degrees and 100 degrees. Of course, the specific angle can be designed according to the actual situation in different models, and is not limited here.

[0069] In one embodiment, the distance between the second flow-blocking surface 220 and the blade 41 gradually increases in the direction away from the rotation axis and gradually decreases in the direction along the rotation direction. The third flow-blocking surface 230 is located at the rear section of the third blade portion 23 facing the stirrer blade 41 in the rotation direction and gradually bends towards the blade 41 along the rotation direction. The angle between the third flow-blocking surface 230 and the second flow-blocking surface 220 can be between 40 degrees and 140 degrees.

[0070] Please see Figure 13 and Figure 14 This embodiment provides a food processor, including a cup body 50 for holding a slurry. The slurry can be a mixture of ingredients such as fruits, vegetables, and water in a certain proportion, chopped and ground to obtain a fluid with a certain degree of fluidity. In this embodiment, the food processor can be equipped with various flow-blocking mechanisms or food processing components mentioned above as needed, and a motor for driving the stirrer 40 to rotate is installed, so that the rotating shaft 42 of the stirrer 40 drives the blades 41 to rotate, ultimately driving the fluid to flow and being repeatedly ground by the blades 41.

[0071] Please see Figure 15 In a preferred embodiment, the data obtained by the inventors through experimental testing is as follows: Figure 15 .exist Figure 15 In comparison with the design without a flow obstruction mechanism, and with the design in this application having a flow obstruction mechanism, keeping the blade speed at the same 11,000 rpm and under the same noise level of 81.49 dB, the preferred embodiment of this application achieves a residue rate of 2.7%, representing an improvement of nearly 50%. Compared to the noise level of existing technologies, the noise level of this application is also correspondingly improved. In terms of cost, this application can also reduce the number of blades 41 by at least one, for example, reducing the upper blade 410 while retaining the middle blade 411 and the lower blade 412, or even retaining only the middle blade, effectively reducing production costs.

[0072] Unlike existing technologies, this application embodiment includes a flow-blocking mechanism, a food processing component, and a food processor. The flow-blocking mechanism, comprising a first fixed frame 10 and blades 20, allows the first flow-blocking surface 210 on the blades 20 to block fluid rotating around the axis of the stirrer 40. Simultaneously, the fluid impacts the blades 20, causing them to rotate with the fluid. The food processing component allows the blades 41 on the stirrer 40 to fully cooperate with the flow-blocking mechanism, obstructing and grinding the slurry. The food processor, with its cup 50, flow-blocking mechanism, and blades 41 working together, causes the fluid to rotate within the cup 50 when the blades 41 rotate. The fluid velocity decreases upon encountering the flow-blocking mechanism, effectively increasing the relative speed between the fluid and blades 41 while maintaining a constant blade rotation speed. This increases the contact frequency between the fluid and blades 41, ultimately improving the grinding effect at lower grinding speeds while reducing noise and enhancing the user experience.

[0073] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
