Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processor. Background Technology

[0002] Existing food processors, such as blenders, typically include a blending jar, a blending blade inside the jar, and a main unit mounted above the jar. The main unit houses a motor assembly. A positioning shaft protrudes upwards from the bottom wall of the blending jar. The blending blade includes a blade shaft and blades arranged around its outer periphery. A positioning hole at the bottom of the blade shaft allows the positioning shaft to insert, and the top of the blade shaft is connected to the output shaft of the motor assembly. In these blenders, the blade shaft needs a certain outer diameter to accommodate the positioning hole, resulting in a relatively thick blade shaft. This causes the blade shaft to occupy a large radial space within the limited space of the blending jar, reducing the radial extension length of the blades and decreasing the effective pulverizing area, thus hindering pulverization efficiency. Furthermore, the thicker blade shaft results in a larger contact area between its bottom surface and the inner bottom surface of the blending jar, increasing the probability of small food particles entering between these surfaces. If food particles become trapped between these surfaces, it can cause instability in the blade shaft's positioning, leading to wobbling.

[0003] There is also a food processing device, for example, a non-drilling meat grinder disclosed in patent CN214554117U, which includes a meat grinding bowl and a meat grinding blade assembly. The meat grinding bowl has a recess in the center of its bottom inner wall, and the lower end of the meat grinding blade assembly has a support column. The support column is used in conjunction with the recess and their positions correspond. This design avoids the blade shaft of the mixing blade assembly being too thick, thus facilitating the expansion of the radial grinding space of the mixing blade. However, due to the recess, during the grinding process, the food will gather towards the center and sink into the recess under the squeezing action of the side wall of the meat grinding bowl and the reinforcing ribs located on the side wall. If food gets trapped in the recess, it will cause unreliable positioning of the mixing blade assembly, resulting in rotational jamming or wobbling, poor rotational stability, or even failure of the mixing blade positioning, leading to grinding failure. Utility Model Content

[0004] This invention provides a food processor in which the mixing cup limits the mixing blade through the mounting groove. This solves the problem of unreliable limiting of the mixing blade caused by food gathering and sinking into the mounting groove, while ensuring that the mixing blade has a sufficient pulverizing area to guarantee the pulverizing effect.

[0005] The technical solution adopted in this utility model is as follows:

[0006] This utility model provides a food processor, including a blending cup and a blending blade installed inside the blending cup. The inner bottom wall of the blending cup has a recessed mounting groove. The blending blade includes a blade shaft and blades disposed on the outer periphery of the blade shaft. The bottom end of the blade shaft is inserted into the mounting groove. A baffle rib is also protruding on the inner bottom wall of the blending cup and located on the outer periphery of the mounting groove. The baffle rib extends radially outward along the inner bottom wall of the blending cup, and the top surface of the baffle rib is arranged radially outward and downward.

[0007] The food processor provided by this utility model features a recessed mounting groove in the inner bottom wall of the mixing cup. This groove limits the bottom end of the blade shaft, reducing the outer diameter of the blade shaft and increasing the radial extension length of the blades. This enlarges the effective pulverizing area of ​​the blades and improves pulverizing efficiency. Furthermore, a baffle rib protrudes from the inner bottom wall of the mixing cup, located around the mounting groove. The top surface of the baffle rib is radially outward and downward. Therefore, when the blade moves the food in a circular motion, the food flows past the baffle rib, and the top surface of the baffle rib guides the food outward, away from the mounting groove. This prevents the food from gathering and getting stuck in the mounting groove, ensuring a reliable limiting fit between the blade shaft and the mounting groove. This prevents the blade from wobbling during operation, improves the stability of the blade, and achieves effective pulverizing. After operation, it also reduces the amount of food remaining in the mounting groove, facilitating thorough cleaning of the mixing cup.

[0008] In addition, since the baffle extends radially outward along the inner bottom wall of the mixing cup, the baffle prevents the food from sticking to the bottom wall of the mixing cup during the rotation of the mixing blade. At the same time, it also has a turbulence effect, causing the food to tumble up and down and circulate in contact with the blade of the mixing blade, so as to crush the food evenly and improve the crushing efficiency.

[0009] In a preferred embodiment, the inner bottom wall of the stirring cup is provided with an upwardly protruding boss, the mounting groove is formed by a downward indentation from the top surface of the boss, the baffle is located on the outer periphery of the boss, and the highest point of the boss is not lower than the highest point of the baffle.

[0010] By providing an upwardly protruding boss on the inner bottom wall of the mixing cup, and forming a mounting groove that is recessed downward from the top surface of the boss, food ingredients need to pass through multiple obstructions from the baffles and the boss to gather from the outer periphery into the mounting groove, increasing the difficulty of food ingredients entering the mounting groove. Moreover, the boss can block food ingredients in all directions along the circumference of the mounting groove. If food ingredients move towards the center between adjacent baffles, the boss can effectively prevent the food ingredients from entering the mounting groove. Therefore, the reliability of the limiting fit between the blade shaft of the mixing blade and the mounting groove is further improved, and the working stability of the mixing blade is further enhanced.

[0011] More preferably, the top surface of the boss is inclined outward and downward to smoothly connect with the top surface of the baffle.

[0012] By tilting the top surface of the boss outwards and downwards and smoothly connecting it to the top surface of the baffle rib, food ingredients need to pass through the baffle rib and the boss to move from the outer periphery towards the center into the mounting groove. Furthermore, the top surface of the boss acts as a guide for the food ingredients to flow outwards, preventing them from remaining on its top surface and reducing the probability of them entering the mounting groove. This also facilitates the flow and pulverization of the food ingredients, improving the stability and pulverization efficiency of the mixing blade. The smooth connection between the top surface of the boss and the top surface of the baffle rib reduces the formation of dead corners where food residue can accumulate, facilitating cleaning and ensuring effective pulverization of the food ingredients.

[0013] In a preferred embodiment, a material receiving groove is formed between adjacent retaining ribs, the bottom wall of the material receiving groove extending radially outward and downward.

[0014] By forming a material trough between adjacent baffles, during the rotation of the mixing blade, the food can rise through the baffles and then sink into the material trough, achieving up-and-down circulation. This ensures full contact with the blades of the mixing blade for effective pulverization. By extending the bottom wall of the material trough radially outward and downward, the material in the trough is guided by the bottom wall to flow away from the outer periphery of the installation trough, preventing it from entering the installation trough. This achieves reliable positioning of the mixing blade within the installation trough and improves the working stability of the mixing blade.

[0015] In a preferred embodiment, an arc-shaped transition wall is provided between the inner bottom wall edge of the mixing cup and the inner side wall of the mixing cup, and the baffle includes an inclined section protruding from the inner bottom wall of the mixing cup and inclined downward and an extension section extending from the inclined section to the transition wall.

[0016] By setting an arc-shaped transition wall between the inner bottom wall edge and the inner side wall of the mixing cup, it is possible to avoid the formation of a dead corner for food residue at the connection between the inner bottom wall and the inner side wall, which facilitates effective crushing of food and thorough cleaning of the mixing cup. In addition, the baffle includes an inclined section and an extension section extending from the inclined section to the transition wall. The extension section protrudes on the transition wall, thus reducing the adhesion of leafy vegetables and some sticky meats to the transition wall, preventing food residue from remaining and achieving effective crushing.

[0017] In a preferred embodiment, multiple baffles are provided, and a turbulence-disrupting rib is protruding on the inner sidewall of the stirring cup, with the turbulence-disrupting rib located between two adjacent baffles.

[0018] By incorporating ribs protruding from the inner wall of the mixing cup, these ribs create a turbulent flow around the rotating ingredients during blade rotation. This prevents leafy vegetables or sticky meats from adhering to the inner wall of the mixing cup, thus achieving effective pulverization. Furthermore, since the ribs are located between adjacent baffles, the rotating blades cause the ingredients to move in a circular motion. The ingredients first move towards the inner wall of the mixing cup through the baffles until they reach the space between the adjacent ribs. Under the combined force of the ribs and the blades, any uncut ingredients fall back into the pulverizing area of ​​the blades. The food is pulverized again and then falls into the area of ​​the baffle. Under the action of the baffle, it flows towards the inner wall of the mixing cup. The chopped food is further pulverized evenly along the inner wall of the mixing cup by the action of the baffle. Therefore, throughout the pulverization process, the food is alternately disturbed by the baffle and the baffle, which can prevent the food from accumulating in local areas of the mixing cup. The baffle and the baffle work together to change the trajectory of the food in a larger area of ​​the mixing cup, thereby increasing the contact opportunity between the food and the blade of the mixing blade and improving the mixing and pulverization effect.

[0019] In a preferred embodiment, a turbulence-disrupting rib is provided on the inner sidewall of the stirring cup, the number and position of which correspond to the baffle rib, and the turbulence-disrupting rib is connected to the baffle rib.

[0020] By corresponding the number and position of the baffle ribs to those of the baffle ribs, the baffle ribs are connected to the baffle ribs. The baffle ribs and baffle ribs work together to create a turbulent flow effect on the food, improving the pulverizing effect, simplifying the molding process of the mixing cup, facilitating manufacturing, and reducing production costs.

[0021] In a preferred embodiment, the retaining rib extends radially outward in a straight line;

[0022] Alternatively, multiple baffles may be provided, each baffle extending radially outward in an arc shape, with the bending direction of the multiple baffles being consistent.

[0023] Whether the baffle extends radially outward in a straight line or an arc, it can cause the food to tumble and circulate for crushing, changing the original flow path of the food and increasing the probability of collision between the food and the blade of the mixing blade, thus achieving efficient crushing. By setting the baffle to extend in an arc shape, and having multiple baffles bend in the same direction, multiple baffles are combined to form a windmill shape. The radial extension length of the baffles is increased, further enhancing the turbulence effect. At the same time, the top surface of the baffles guides the material to flow away from the outer periphery of the mounting groove, effectively improving the working stability of the mixing blade.

[0024] In a preferred embodiment, the retaining rib has a converging section near the mounting groove, the width of which gradually decreases toward the mounting groove.

[0025] By setting a gathering section with its width gradually decreasing towards the mounting groove, the gap between adjacent baffles becomes smaller closer to the mounting groove. By reducing the width of the gathering section itself, an effective material trough is formed between adjacent baffles, which can accommodate the material. Thus, in the direction of the stirring blade's rotation, the material achieves a good circulating crushing effect after passing through the baffles and the material trough, preventing the material from adhering to the inner wall of the stirring cup.

[0026] In a preferred embodiment, a first magnetic element is fixed to the bottom end of the blade shaft of the stirring blade, and a second magnetic element that can be attracted to the first magnetic element is fixed to the outer bottom wall of the stirring cup.

[0027] By setting a first magnetic suction component and a second magnetic suction component, the two are attracted to each other so that the bottom end of the blade shaft of the stirring blade is attracted to the stirring cup. On the basis of the mounting groove limiting the blade shaft, the first magnetic suction component and the second magnetic suction component work together to further improve the stability of the fit between the blade shaft and the mounting groove, prevent the blade shaft from coming out of the mounting groove during operation, achieve reliable limiting, and further reduce the blade shaft wobble, thereby reducing the tilt gap between the blade shaft and one side of the mounting groove, and preventing the material from being hidden in the mounting groove through the gap.

[0028] In a preferred embodiment, the radial inner ends of the plurality of the retaining ribs are all connected to the slot of the mounting groove.

[0029] The radial inner ends of the multiple baffles are connected to the opening of the mounting groove. Therefore, the food around the periphery of the mounting groove can flow radially outward along the top surface of the baffles without flowing into the mounting groove and causing the stirring blade to get stuck.

[0030] In a preferred embodiment, the inner bottom wall of the stirring cup is provided with an upwardly protruding boss, and the mounting groove is formed by a downward recess from the top surface of the boss, and the depth h1 of the mounting groove satisfies 4mm≤h1≤20mm.

[0031] If the depth of the mounting groove is too small, such as less than 4mm, the cutter shaft will easily detach from the mounting groove, resulting in poor limiting reliability. If the depth is greater than 20mm, the mixing cup will be difficult to form and the processing cost will be high. Therefore, the requirement of 4mm≤h1≤20mm ensures that the mounting groove can reliably limit the cutter shaft and facilitates the manufacturing of the mixing cup.

[0032] In a preferred embodiment, the inner bottom wall of the stirring cup is provided with an upwardly protruding boss, and the mounting groove is formed by a downward recess from the top surface of the boss, wherein the protrusion height h2 of the boss is less than the depth h1 of the mounting groove.

[0033] By setting a boss to locally thicken the inner bottom wall of the mixing cup, and the mounting groove is formed by recessing downward from the top surface of the boss, and the protrusion height h2 of the boss is less than the depth h1 of the mounting groove, it is not necessary to thicken the entire inner wall of the mixing cup, thereby reducing the weight of the mixing cup and facilitating the molding and processing of the mixing cup.

[0044] Many specific details are set forth in the following description to provide a full understanding of the present invention.

Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model.

[0048] like Figure 1 , 2As shown, in one embodiment, this utility model provides a food processor, including a blending cup 10 and a blending blade 20 installed inside the blending cup 10. The inner bottom wall 11 of the blending cup 10 has a recessed mounting groove 30. The blending blade 20 includes a blade shaft 21 and blades 22 disposed around the outer periphery of the blade shaft 21. The bottom end of the blade shaft 21 is inserted into the mounting groove 30. A retaining rib 40 protrudes from the inner bottom wall 11 of the blending cup 10 and is located around the mounting groove 30. Figure 2 As shown, the baffle 40 extends radially outward along the inner bottom wall 11 of the stirring cup 10, and the top surface of the baffle 40 is arranged radially outward and downward.

[0049] The food processor provided by this utility model features a recessed mounting groove 30 in the inner bottom wall 11 of the mixing cup 10. This groove 30 limits the bottom end of the blade shaft 21 of the mixing blade 20, reducing the outer diameter of the blade shaft 21 and increasing the radial extension length of the blade 22. This increases the effective pulverizing area of ​​the mixing blade 20 and improves pulverizing efficiency. Furthermore, a baffle 40 protrudes from the inner bottom wall 11 of the mixing cup 10, located around the mounting groove 30. The top surface of the baffle 40 is radially outward and downward. Therefore, when the mixing blade moves the food in a circular motion, the food flows past the baffle 40, and the top surface of the baffle 40 guides the food outward. Figure 2 As indicated by the arrow, the blade is positioned away from the mounting slot 30, thus preventing food from gathering and getting stuck inside the mounting slot 30. This ensures that the blade shaft 21 of the mixing blade 20 and the mounting slot 30 can reliably engage, preventing the mixing blade 20 from wobbling during operation, improving the working stability of the mixing blade 20, and achieving effective pulverization. After operation, it also reduces the amount of food hidden in the mounting slot 30, making it easier to thoroughly clean the mixing cup 10.

[0050] In addition, since the baffle 40 extends radially outward along the inner bottom wall 11 of the mixing cup 10, the baffle 40 prevents the food from sticking to the bottom wall of the mixing cup 10 during the rotation of the mixing blade 20. At the same time, it also plays a turbulence role, causing the food to roll up and down and circulate in contact with the blade 22 of the mixing blade 20, so as to crush it evenly and improve the crushing efficiency of the food.

[0051] It should be noted that the food processor provided by this utility model can be electrically driven. For example, the food processor also includes a main unit installed above the mixing cup 10, and the main unit is provided with a motor assembly that drives the mixing blade 20; of course, the food processor can also be manual.

[0052] In addition, one or more baffles 40 can be provided on the inner bottom wall of the mixing cup in this utility model. As long as the material flows through the baffle 40, it can flow outward under the guidance of the top surface of the baffle 40, avoiding getting stuck in the mounting groove 30. Of course, when multiple baffles 40 are provided, when the mixing blade rotates and drives the material to move in a circular motion, the material will surge up through one baffle 40, then fall between adjacent baffles 40, and then surge up over the next baffle 40, so as to form an up-and-down surging in the mixing cup, fully contacting the blade 22 to achieve a good crushing effect, and preventing the material from sticking to the bottom wall of the mixing cup. Moreover, each time it passes through a baffle 40, it can flow outward and will not surge into the mounting groove 30.

[0053] More preferably, a plurality of retaining ribs 40 are evenly spaced around the outer periphery of the mounting groove 30. Of course, the present invention is not limited thereto.

[0054] Furthermore, this utility model does not limit the shape of the retaining rib 40, for example:

[0055] Implementation Example 1, such as Figure 1 , 2 As shown, the retaining rib 40 extends outward in a straight line along the radial direction;

[0056] Implementation Example 2, such as Figure 3-6 As shown, the baffle 40 extends radially outward in an arc shape. When multiple baffles are provided, the bending direction of the multiple baffles 40 is consistent, so that the multiple baffles 40 are combined to form a windmill shape.

[0057] It is understandable that whether the baffle 40 extends outward in a straight line or an arc, it can make the food roll up and down, circulate and crush, change the original flow path of the food, increase the probability of the food colliding with the blade 22 of the mixing blade 20, and achieve efficient crushing. By setting the baffle 40 to extend in an arc and the bending direction of multiple baffles 40 is consistent, multiple baffles 40 are combined to form a windmill shape. The radial extension length of the baffle 40 is increased, which further enhances the turbulence effect. At the same time, the top surface of the baffle 40 guides the material to flow away from the outer periphery of the mounting groove 30, which effectively improves the working stability of the mixing blade 20.

[0058] This utility model does not limit the connection method between the retaining rib and the mounting groove:

[0059] In a preferred embodiment, such as in Example 1, as Figure 1 , 2 As shown, the radial inner ends of the retaining ribs 40 are all connected to the slots of the mounting grooves 30.

[0060] The radial inner ends of the baffle 40 are all connected to the opening of the mounting groove 30. Therefore, the food around the outer periphery of the mounting groove 30 can flow radially outward along the top surface of the baffle 40 without flowing into the mounting groove 30 and causing the stirring blade 20 to get stuck.

[0061] It is understood that the connection method between the retaining rib and the mounting groove in this embodiment is not limited to the retaining rib structure of embodiment example 1, but can also be combined with the retaining rib structure of other embodiments.

[0062] In another preferred embodiment, such as in Example 2, a boss structure is provided between the retaining rib and the mounting groove, as shown in the figure. Figure 3-6 As shown, the inner bottom wall 11 of the stirring cup 10 is provided with an upwardly protruding boss 50, the mounting groove 30 is formed by recessing downward from the top surface of the boss 50, the baffle 40 is located on the outer periphery of the boss 50, and the highest point of the boss 50 is not lower than the highest point of the baffle 40.

[0063] By providing an upwardly protruding boss 50 on the inner bottom wall 11 of the mixing cup 10, and the mounting groove 30 being recessed downward from the top surface of the boss 50, if food wants to gather from the outer periphery to the center and enter the mounting groove 30, it needs to pass through the multiple obstructions of the baffle 40 and the boss 50, increasing the difficulty for the food to enter the mounting groove 30. Moreover, the boss 50 can block the food in all directions around the mounting groove 30. If food moves towards the center between adjacent baffles 40, the boss 50 can effectively prevent the food from entering the mounting groove 30. Therefore, the reliability of the limiting fit between the blade shaft 21 of the mixing blade 20 and the mounting groove 30 is further improved, and the working stability of the mixing blade 20 is further improved.

[0064] More preferably, such as Figure 6 As shown, the top surface of the boss 50 is inclined outward and downward to smoothly connect with the top surface of the baffle 40.

[0065] By tilting the top surface of the boss 50 outwards and downwards and smoothly connecting it to the top surface of the baffle 40, food ingredients need to pass through the baffle 40 and the boss 50 to move from the outer periphery to the center and enter the mounting groove 30. Furthermore, the top surface of the boss 50 guides the food ingredients outwards, preventing them from remaining on its surface and reducing the probability of them entering the mounting groove 30. This also facilitates the flow and crushing of the food, improving the working stability and crushing efficiency of the mixing blade 20. The smooth connection between the top surface of the boss 50 and the top surface of the baffle 40 reduces the formation of dead corners where food residue can accumulate, facilitating cleaning and ensuring effective crushing of the food ingredients.

[0066] Similarly, the connection method between the retaining rib and the mounting groove in this embodiment is not limited to being combined with the retaining rib structure of Embodiment 2, but can also be combined with the retaining rib structure of other embodiments.

[0067] In a preferred embodiment, such as Figure 3 As shown, the depth h1 of the mounting groove 30 satisfies 4mm≤h1≤20mm.

[0068] Because if the depth of the mounting groove 30 is too small, if the depth is less than 4mm, the cutter shaft 21 will easily detach from the mounting groove 30, resulting in poor limiting reliability. If the depth is greater than 20mm, the mixing cup 10 will be difficult to form and the processing cost will be high. Therefore, if the depth is 4mm≤h1≤20mm, the mounting groove 30 can reliably limit the cutter shaft 21, and the mixing cup 10 can be easily manufactured.

[0069] In a preferred embodiment, such as Figure 3 As shown, the inner bottom wall of the mixing cup has an upwardly protruding boss 50, and a mounting groove 30 is formed by recessing downwards from the top surface of the boss 50. The protrusion height h2 of the boss 50 is less than the depth h1 of the mounting groove 30. By setting the boss 50 to locally thicken the inner bottom wall of the mixing cup, and by forming the mounting groove from the top surface of the boss 50 downwards with the protrusion height h2 of the boss 50 being less than the depth h1 of the mounting groove, it is not necessary to thicken the entire inner wall of the mixing cup, thus reducing the weight of the mixing cup and facilitating its molding and processing.

[0070] In a preferred embodiment, refer to Figure 4 As shown, a material receiving groove 60 is formed between adjacent retaining ribs 40, combined with... Figure 6 The bottom wall of the material container 60 extends radially outward and downward.

[0071] By forming a material trough 60 between adjacent baffles 40, during the rotation of the stirring blade 20, the food can surge upward through the baffles 40 and then sink into the material trough 60, achieving up-and-down circulation, so as to fully contact the blade 22 of the stirring blade 20 and achieve good crushing; by extending the bottom wall of the material trough 60 radially outward and downward, the material in the material trough 60 flows away from the outer periphery of the mounting groove 30 under the guidance of the bottom wall, and does not enter the mounting groove 30, so as to achieve reliable limiting of the stirring blade 20 in the mounting groove 30 and improve the working stability of the stirring blade 20.

[0072] In a preferred embodiment, combined with Figure 4 , 5As shown, an arc-shaped transition wall 12 is provided between the edge of the inner bottom wall 11 of the mixing cup 10 and the inner side wall 13 of the mixing cup 10. The baffle 40 includes an inclined section 41 protruding from the inner bottom wall 11 of the mixing cup 10 and inclined downward, and an extension section 42 extending from the inclined section 41 to the transition wall 12.

[0073] By providing an arc-shaped transition wall 12 between the edge of the inner bottom wall 11 and the inner side wall 13 of the mixing cup 10, it is possible to avoid the formation of a dead corner for food residue at the connection between the inner bottom wall 11 and the inner side wall 13, which facilitates effective crushing of food and thorough cleaning of the mixing cup 10. In addition, the baffle 40 includes an inclined section 41 and an extension section 42 extending from the inclined section 41 to the transition wall 12. The extension section 42 protrudes on the transition wall 12, thus reducing the adhesion of leafy vegetables and some sticky meats to the transition wall 12, preventing food residue from remaining and achieving effective crushing.

[0074] In a preferred embodiment of this invention, a turbulence-inducing rib 70 is protruding from the inner sidewall 13 of the stirring cup 10, such as... Figure 4 As shown, the turbulence rib 70 is located between two adjacent baffle ribs 40.

[0075] By providing turbulence ribs 70 on the inner wall 13 of the mixing cup 10, the turbulence ribs 70 turbulently move the rotating ingredients during the rotation of the mixing blade 20, preventing leafy vegetables or sticky meats from adhering to the inner wall 13 of the mixing cup 10, thus achieving effective pulverization of the ingredients. Furthermore, since the turbulence ribs 70 are located between two adjacent baffle ribs 40, the rotating mixing blade 20 drives the ingredients in a circular motion during pulverization. The ingredients first move towards the inner wall of the mixing cup 10 through the baffle ribs 40 to between the adjacent turbulence ribs 70. Under the combined force of the turbulence ribs 70 and the blade 22, any un-pulverized ingredients fall back into the pulverization area of ​​the mixing blade for further pulverization, and then... The food falls into the area of ​​the baffle 40 and flows towards the inner wall of the mixing cup 10 under the action of the baffle 40. The chopped food is then further pulverized by the turbulence 70 along the inner wall of the mixing cup 10 until it falls to the bottom of the mixing cup 10. Therefore, during the entire pulverization process, the food is alternately disturbed by the baffle 40 and the turbulence 70. This alternating disturbance of the food by the baffle 40 and the turbulence 70 can prevent the accumulation of food in local areas within the mixing cup 10. The baffle 40 and the turbulence 70 work together to change the trajectory of the food within a larger area of ​​the mixing cup 10, thereby increasing the contact opportunity between the food and the blade 22 of the mixing blade 20 and improving the mixing and pulverization effect.

[0076] Of course, the location of the baffles and baffles is not limited to the one mentioned above. In another preferred embodiment, for example:

[0077] Implementation Example 3, such as Figure 7 As shown, a turbulence rib 70 is protruding from the inner sidewall 13 of the stirring cup 10. The number and position of the turbulence rib 70 correspond to those of the baffle rib 40, and the turbulence rib 70 is connected to the baffle rib 40.

[0078] By corresponding the number and position of the baffle ribs 70 and the baffle ribs 40, the baffle ribs 70 and the baffle ribs 40 are connected. The baffle ribs 70 and the baffle ribs 40 work together to turbulent the food, improve the crushing effect, simplify the molding process of the mixing cup 10, facilitate processing and manufacturing, and reduce production costs.

[0079] Of course, in reality, the deflector 70 and the baffle 40 can also be positioned correspondingly, that is, their projections in the horizontal direction are on the same straight line, but the two are not connected.

[0080] In a preferred embodiment, such as Figure 7 As shown, the retaining rib 40 has a converging section 43 near the mounting groove 30, and the width W of the converging section 43 gradually decreases toward the mounting groove 30.

[0081] By setting a gathering section with its width gradually decreasing towards the mounting groove 30, the gap between adjacent baffles 40 is smaller closer to the mounting groove 30. By reducing the width of the gathering section, an effective material trough 60 is formed between adjacent baffles 40, which can accommodate the material. Thus, in the rotation direction of the stirring blade 20, the material achieves a good circulating crushing effect after passing through the baffles 40 and the material trough 60, preventing the material from adhering to the inner wall of the stirring cup 10.

[0082] In a preferred embodiment, for example Figure 2 , 3 As shown, a first magnetic attractor 81 is fixed at the bottom end of the blade shaft 21 of the stirring blade 20, and a second magnetic attractor 82 that can be attracted to the first magnetic attractor 81 is fixed on the outer bottom wall of the stirring cup 10.

[0083] The installation of the first magnetic 81 and the second magnetic 82 can be configured as follows: a mounting hole is provided at the bottom end of the cutter shaft 21, the first magnetic 81 is embedded in the mounting hole, a first bottom cover is fixedly provided at the bottom end of the cutter shaft, and the first bottom cover encapsulates the first magnetic 82 in the mounting hole; a groove is provided on the outer bottom wall of the stirring cup 10, the second magnetic 82 is installed in the groove, and a second bottom cover is encapsulated at the groove opening, and the second bottom cover encapsulates the second magnetic 82 in the groove.

[0084] In addition, one of the first magnetic attraction member 81 and the second magnetic attraction member 82 is a magnet, and the other can be a magnet or a metal part;

[0085] By setting the first magnetic suction component 81 and the second magnetic suction component 82, the two are attracted to each other so that the bottom end of the blade shaft 21 of the stirring blade 20 is attracted to the stirring cup 10. Based on the limiting of the blade shaft 21 by the mounting groove 30, the first magnetic suction component 81 and the second magnetic suction component 82 work together to further improve the stability of the fit between the blade shaft 21 and the mounting groove 30, and prevent the blade shaft 21 from coming out of the mounting groove 30 during operation, thus achieving reliable limiting.
