Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of small household appliances, in particular to a stirring blade and a food processor. BACKGROUND

[0002] Some food processors, the knife assembly includes a single blade or a double blade, the number of blades and blades is small, which makes the vortex generated by the knife assembly when stirring small, poor stirring effect. In addition, for the non-detachable knife assembly, it is difficult to clean, especially the knife assembly with more blades or blades, which can cause more food residues to remain, and further more easily breed bacteria. SUMMARY

[0003] The present application provides a stirring blade and a food processor, which can improve the cutting and crushing effect and facilitate cleaning.

[0004] A stirring blade, comprising

[0005] a blade shaft;

[0006] a blade head comprising a blade sleeve and a first blade, a second blade and a third blade connected to the blade sleeve, the blade sleeve being provided with a shaft hole for the blade shaft to pass through, the blade shaft being detachably mounted in the shaft hole and being in circumferential transmission connection with the blade head, the first blade, the second blade and the third blade being arranged in sequence along the axial direction of the blade shaft, the first blade comprising one or more first blade wings bent away from the second blade, the second blade comprising one or more second blade wings, and the third blade comprising one or more third blade wings bent away from the second blade.

[0007] The stirring blade provided by the present application has a large number of blades, and the number of blade wings is also increased, which can fully mix food materials and form a better vortex state during stirring, ensuring that there is no dead angle for cutting and crushing, and improving the crushing effect. In addition, the detachable blade head can be separated from the blade shaft, which is more convenient for cleaning.

[0008] Optionally, the second blade wings are provided in an even number, and at least two of the second blade wings are provided as flat blade wings without bending. The flat blade wings are in a horizontal state, and the radial dimension of the blade part is large, so that the contact area of the flat blade wings with food materials is increased, the space of the cup cavity is fully utilized, and the crushing effect is better.

[0009] Optionally, the at least two flat blade wings comprise a first flat blade wing and a second flat blade wing, the first flat blade wing and the second flat blade wing are arranged at an interval of 180° and are symmetrical about the axis of the blade shaft. In this way, the mass distribution is uniform, and the motion is stable.

[0010] Optionally, the flat blade includes an arc-shaped cutting edge with a radius of 15mm to 40mm. The flat blade and the arc-shaped extension of the cutting edge increase the length of the cutting edge, thereby increasing the contact area with the food.

[0011] Optionally, at least two of the second blades are configured as bent blades. The bent blades can better turbulentize the feed, causing the feed to continuously generate vortices. This allows for simultaneous cutting and mixing of the feed, ensuring that there are no dead angles in the cutting and crushing process.

[0012] Optionally, the folding blade includes a first folding blade and a second folding blade that are connected. In the radial direction of the blade axis, the first folding blade is closer to the blade axis than the second folding blade, and the bending direction of the first folding blade is opposite to that of the second folding blade. This configuration ensures that the folding blade bends at at least two locations, and the cutting edge bends accordingly. This facilitates convection between the upper and lower layers of food, resulting in better mixing and cutting of the food.

[0013] Optionally, the first bending wing bends away from the first blade, while the second bending wing bends towards the first blade. This configuration allows the turbulence area of ​​the bending blades to be closer to the bottom of the cup cavity, which is more conducive to the flow of food at the bottom of the cup cavity and can prevent food from sticking to the bottom.

[0014] Optionally, the angle between the first bending wing and the cutter axis is 110° to 130°; and / or

[0015] The angle between the second bending blade and the blade axis is 90° to 110°. With this configuration, the bending blade forms a moderate bend at at least two locations, which not only ensures a large turbulence radius of the bending blade but also effectively achieves convection between the upper and lower layers of food.

[0016] Optionally, the second blade is configured as an odd number of unbent flat blades, including at least a first flat blade, a second flat blade, and a third flat blade. The first, second, and third flat blades are evenly distributed along the circumference of the blade axis, with the axis of the blade axis as the center. The maximum diameter of the circumference of the blade tips of the first, second, and third flat blades is 55mm to 58mm. This configuration, with at least three flat blades, increases the number of blades and their radial dimensions, thereby increasing the contact area with the food.

[0017] Optionally, at least one of the first blades has an angle of 30° to 70° with the blade axis. The range of this angle α allows the cutting diameter of the first blade 51 to be within a suitable range.

[0018] Optionally, with the axis of the cutter shaft as the center, the maximum diameter of the circumference where the tip of the first cutter blade is located is set to 0.4 to 1 times the maximum diameter of the circumference where the tip of the second cutter blade is located. With this configuration, the cutting area of ​​the first cutter blade is located in the upper layer and close to the axis, while the second cutter blade can fully utilize the space within the cup cavity, allowing for sufficient contact with the food, resulting in a larger contact area and improved pulverization effect.

[0019] Optionally, with the axis of the cutter shaft as the center, the maximum diameter of the circumference of the first blade tip is set to 35mm to 55mm. This configuration allows for cutting and crushing of the upper layer of food near the axis.

[0020] Optionally, with the axis of the cutter shaft as the center, the maximum diameter of the circumference where the tip of the third cutter wing is located is set to 0.3 to 0.8 times the maximum diameter of the circumference where the tip of the second cutter wing is located. With this configuration, the cutting area of ​​the third cutter wing is located in the lower layer and close to the axis, while the radial dimension of the second cutter wing along the cutter shaft is relatively large. This allows the second cutter wing to fully utilize the space within the cup cavity, ensuring sufficient contact with the food and guaranteeing thorough cutting and pulverization without any blind spots.

[0021] Optionally, with the axis of the cutter shaft as the center, the maximum diameter of the circumference of the tip of the third cutter blade is set to 25mm to 45mm. This configuration allows for cutting and crushing of the lower layer of food material near the axis.

[0022] Optionally, the angle between the third blade and the blade axis is 40° to 70°. The angle β determines the size of the turbulence radius of the third blade. The third blade is located below the second blade and acts as a secondary blade. Its main function is to turbulent and crush the lower layer of food in the cup cavity. The range of values ​​for the angle β allows the cutting diameter of the third blade to be within a suitable range.

[0023] Optionally, the first blade includes two first blades spaced 180° apart, and the second blade includes four second blades evenly distributed circumferentially along the blade axis, two of which are flat blades spaced 180° apart and are not bent, while the other two are bent blades spaced 180° apart. The third blade includes two third blades spaced 180° apart. The arrangement direction of the two first blades is different from the arrangement direction of the two third blades; one of the blades is aligned with the arrangement direction of the two flat blades, and the other is aligned with the arrangement direction of the two bent blades. In this design, the number of second blades is relatively large, including both flat and bent blades. As the main cutting blade, the second blade has strong turbulence and cutting capabilities, enabling cutting and crushing without dead angles.

[0024] Optionally, the first blade includes three first blades evenly distributed along the circumference of the cutter axis, the second blade includes three second blades evenly distributed along the circumference of the cutter axis, all of the second blades being flat blades without bending, and the third blade includes two third blades spaced 180° apart. In the orthographic projection along the axial direction of the cutter axis, the projection of each first blade is located at the exact midpoint of the angle between two adjacent second blades, and the arrangement direction of the two third blades is consistent with the direction of the angle bisector of any two adjacent second blades. In this scheme, the number of first and second blades is the same, and their distribution along the cutter axis is relatively dispersed and uniform. The second blade serves as the main cutting blade, and the first and third blades are distributed on the upper and lower sides of the second blade, serving as turbulence and auxiliary cutting, enabling cutting and crushing without dead angles.

[0026] Base;

[0027] A cup assembly, assembled to the base, includes a cup body and a blending blade as described above.

[0051] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a food processor 100 shown as an exemplary embodiment of this application.

[0052] This application provides a food processor 100, including a base 10 and a cup assembly 20 assembled on top of the base 10, the cup assembly 20 being detachably assembled to the base 10, but not limited thereto.

[0053] exist Figure 1 In the illustrated embodiment, the food processor 100 further includes a soundproof cover 30, which covers the outside of the cup assembly 20 to isolate noise during food blending. The soundproof cover 30 can be supported or snapped onto the base 10, and a sealing element can be provided at the contact point between the soundproof cover 30 and the base 10 to seal the gap between them. The sealing element can be located on the soundproof cover 30 or on the base 10.

[0054] Please refer to Figure 2 , Figure 2 for Figure 1 The image shows a cross-sectional view of the food processor 100.

[0055] The base 10 includes a housing 11, a circuit board 12 housed within the housing 11, a lower coupler 13, a control panel 14 mounted on the outer surface of the housing 11, and a power cord 15 connected to the circuit board 12. The power cord 15 extends from the housing 11 for connection to mains power. The lower coupler 13 is used for coupling with the cup assembly 20. The control panel 14 allows the user to input control commands to control the food processor 100 to execute the food preparation program corresponding to the current command.

[0056] The cup assembly 20 includes a cup body 21, a cup holder 22 disposed at the bottom of the cup body 21, and a stirring blade 23. The cup body 21 includes a cup cavity 210 for containing food. The cup holder 22 includes a motor 221 and an upper coupler 222 for coupling with a lower coupler 13. Multiple upper couplers 222 and lower couplers 13 can be provided and coupled one-to-one. The motor 221 drives the stirring blade 23 to rotate. In some other embodiments, the motor 221 may also be disposed within the base 10.

[0057] Please refer to Figure 3 , Figure 3 yes Figure 1 An exploded view of the cup assembly 20 in an inverted state, shown in the figure.

[0058] The cup holder 22 also includes a cup holder housing 220, a motor 221, and an upper coupler 222 housed within the cup holder housing 220. Two upper couplers 222 are provided, each installed at a coupler hole 2200 at the bottom of the housing 220, with the terminals of the upper couplers 222 exposed through the coupler holes 2200. The motor 221 is mounted to a motor bracket 224 using screws 223, and the motor bracket 224 is fixed within the cup holder housing 220.

[0059] The cup body 21 includes a hollow cup cylinder 211 and a blade disc 212 assembled at the bottom of the cup cylinder 211. A sealing ring 213 is provided between the cup cylinder 211 and the blade disc 212 to seal the gap between them. The cup cylinder 211 and the blade disc 212 together form a cup cavity 210, and the stirring blade 23 is disposed within the cup cavity 210 of the cup body 21. The cup cylinder 211 can be made of glass, but is not limited to this material. The blade disc 212 can be configured as a heating plate. Specifically, the blade disc 212 is provided with a heating element 214 and a temperature controller 215. The heating element 214 can be an electric heating tube, but is not limited to this material. The temperature controller 215 is fixed to the blade disc 212 by screws 216. The temperature controller 215 can be a temperature sensor. A through hole 2120 is provided at the center of the blade disc 212 through which the output shaft of the power supply motor 221 passes. The cup holder 211 is provided with a handle 217 for easy handling. The handle 217 can be integrally formed with the cup holder 211, or the handle 217 can be formed separately and assembled with the cup holder 211.

[0060] Please refer to Figures 4 to 6 , Figure 4 This is a cross-sectional view of the cup assembly 20 shown in Figure 1. Figure 5 This is an exploded view of the motor 221 and the stirring blade 23. Figure 6 This is an exploded view of one embodiment of the blade 231.

[0061] like Figure 4As shown, the stirring blade 23 includes a blade shaft 230 and a blade head 231 detachably assembled to the blade shaft 230. The blade head 231 is circumferentially connected to the blade shaft 230. The blade head 231 is located within the cup cavity 210, and the blade shaft 230 is connected to the output shaft of the motor 221. Figure 4 In the embodiment shown, the cutter shaft 230 and the output shaft of the motor 221 are configured as an integral structure.

[0062] like Figure 5 and Figure 6 As shown, the cutting head 231 includes a cutting sleeve 50 and a first blade 51, a second blade 52, and a third blade 53 connected to the cutting sleeve 50. The cutting sleeve 50 has a shaft hole 501 through which the cutting shaft 230 passes. The cutting shaft 230 is detachably installed in the shaft hole 501 and is circumferentially connected to the cutting head 231. The first blade 51, the second blade 52, and the third blade 53 are arranged sequentially from top to bottom along the axial direction of the cutting shaft 230. The first blade 51 includes one or more first blade wings 510 bent away from the second blade 52, the second blade 52 includes one or more second blade wings 520, and the third blade 53 includes one or more third blade wings 530 bent away from the second blade 52.

[0063] As described above, the cutter head 231 is configured with a stacked first blade 51, a second blade 52, and a third blade 53. The increased number of blades and blade wings allows for thorough mixing of the food and the formation of a better vortex during the mixing process. Specifically, the first blade 510 stirs and pulverizes the food in the upper part of the cup cavity 210 near the axis, the third blade 530 stirs and pulverizes the food in the lower part of the cup cavity 210 near the axis, and the second blade 520 mixes the upper and lower layers of food and generates a vortex while also pulverizing the food, ensuring thorough cutting and pulverization without dead angles and improving the pulverization effect. Furthermore, the detachable cutter head 231 can be separated from the blade shaft 230, making cleaning easier.

[0064] In one embodiment, the shaft hole 501 is configured as a square hole, and the cutter shaft 230 is configured as a square shaft, thus achieving circumferential transmission between the cutter shaft 230 and the cutter head 231. In this embodiment, as shown... Figure 5As shown, the cutter shaft 230 has multiple protruding ribs 2301 extending spirally around the axis of the cutter shaft, and the multiple protruding ribs 2301 are distributed at intervals along the circumference of the cutter shaft. Correspondingly, the inner wall of the shaft hole 501 has multiple grooves (not shown) that mate with the protruding ribs 2301, and the multiple protruding ribs 2301 and the multiple grooves are in clearance fit. The spiral direction of the protruding ribs 2301 is set to be opposite to the direction of rotation of the cutter shaft 230. With this configuration, during rotation, the protruding ribs 2301 abut against the cutter sleeve 50 in the groove. This abutting force can realize power transmission, and this abutting force has a downward component. That is to say, the spiral protruding ribs 2301 have a downward restricting effect on the cutter head 231, so that the cutter head 231 cannot move upward and disengage from the cutter shaft 230 during high-speed rotation. It should be noted that the number of protruding ribs 2301 is not limited; there can be two, three, four, or more. Multiple protruding ribs 2301 can improve the coaxiality of the tool sleeve 50 when it is installed on the tool shaft 230, and make the force more balanced during circumferential transmission. This results in less resonance between the cup assembly 20 and the base 10, lower noise, and a better user experience. Of course, in some other embodiments, there may be only one protruding rib 2301.

[0065] Please combine Figure 6 and Figure 7 , Figure 7 This is a cross-sectional view of the motor 221 and the stirring blade 23 in their assembled state.

[0066] In one embodiment, the blade sheath 50 includes an inner sleeve 50a and an outer sleeve 50b fitted around the outer side of the inner sleeve 50a. The inner sleeve 50a is a T-shaped sleeve, with its small end connected to the outer sleeve 50b and its large end located outside the outer sleeve 50b. The first blade 51, the second blade 52, and the third blade 53 are clamped and fixed between the inner sleeve 50a and the outer sleeve 50b, more specifically, between the large end of the inner sleeve 50a and the bottom surface of the outer sleeve 50b. The small end of the inner sleeve 50a and the outer sleeve 50b can be connected by threads, but are not limited to this.

[0067] The blade sheath 50 may also include an annular washer 54, which can be clamped between the third blade 53 and the inner sleeve 50a. The surface of the annular washer 54 is provided with a groove, which can increase the friction between the inner sleeve 50a and the annular washer 54 and prevent the inner sleeve 50a from loosening.

[0068] The blade sheath 50 may further include a blade cap 55 connected to the top of the outer sleeve 50b and a sealing ring 56 disposed within the blade cap 55. The blade shaft 230 is configured as a stepped shaft, with the end of the blade shaft 230 extending from the top of the outer sleeve 50b being the smaller end. The outer sleeve 50b is supported on the stepped surface of the blade shaft 230. The blade cap 55 is connected to the outer sleeve 50b, and the connection method is not limited. The sealing ring 56 is sleeved on the smaller end of the blade shaft 230 and is clamped and fixed between the blade cap 55 and the outer sleeve 50b. The sealing ring 56 is used to seal the gap between the outer sleeve 50b and the blade shaft 230 to prevent food from entering the blade sheath 50. Of course, in some other embodiments, a seal may also be provided between the outer sleeve 50b and the blade shaft 230, and the blade cap 55 is not necessary. The outer surface of the outer sleeve 50b is also provided with a handle 502 for easy handling. The handle 502 may be configured as a protrusion or a recess; in this embodiment, the latter is used.

[0069] The cutter head 231 is assembled from bottom to top. The first blade 51, the second blade 52, the third blade 53, and the annular gasket 54 are fitted into the small end of the inner sleeve 50a. The small end of the inner sleeve 50a is screwed into the outer sleeve 50a and fixed by threaded connection. The sealing ring 56 is installed into the cutter cover 55, and the cutter cover 55 and the outer sleeve 50a are fixed by laser welding.

[0070] In one embodiment, such as Figure 7 As shown, motor 221 can be a brushless motor. Motor 221 includes a rotor 2110 and a stator 2112 surrounding the rotor 2110. The stator 2112 is fixed to the inner side of the motor housing 2114. A ball bearing 2111, a washer 2113, and an oil seal 2115 are provided between the motor housing 2114 and the motor output shaft to ensure the rotation and sealing of the output shaft. The output shaft rotates synchronously with the rotor 2110. A shock-absorbing pad 2116 is also provided on the motor housing 2114 to absorb and isolate vibration.

[0071] Please refer to Figure 8 and Figure 9 , Figure 8 This is the main view of the first blade 51. Figure 9 This is a left view of the first blade 51.

[0072] In one embodiment, the first blade 51 includes one or more first blade wings 510, each first blade wing 510 being bent upwards, and at least one first blade wing 510 forming an angle α with the axis O of the blade shaft 230 of 30° to 70°. For example, the angle α can be set to 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, or 70°, but is not limited to these. The angle α determines the size of the turbulence radius of the first blade 51. The first blade 51 is positioned above the second blade 52 and acts as a secondary blade, its main function being to turbulent and pulverize the upper layer of food in the cup cavity 210. The range of values ​​for the angle α allows the cutting diameter of the first blade 51 to be within a suitable range.

[0073] In one specific embodiment, with the axis of the cutter shaft 230 as the center, the maximum diameter φ1 of the circumference of the tip of the first cutter blade 510 is 35mm to 55mm, which is the cutting diameter of the first blade 51. The maximum diameter φ1 can be set to 35mm, 40mm, 45mm, 50mm, or 55mm, but is not limited to these. This setting allows for the cutting and crushing of the upper layer of food near the axis.

[0074] In this embodiment, the first blade 51 includes two first blade wings 510. The two first blade wings 510 are spaced 180° apart and symmetrically arranged about the axis of the blade shaft 230. The tips of the two first blade wings 510 are arranged on the same circumference with the axis of the blade shaft 230 as the center. This makes the center of gravity of the first blade 51 coincide with the axis of the blade shaft 230, resulting in uniform mass distribution and better motion stability.

[0075] Please refer to Figure 10 , Figure 10 This is a bottom view of another embodiment of the blade 232.

[0076] In one embodiment, with the axis of the cutter shaft 230 as the center, the maximum diameter φ1 of the circumference where the tip of the first blade 510 is located is set to 0.4 to 1 times the maximum diameter φ2 of the circumference where the tip of the second blade 520 is located. For example, it can be 0.4 times, 0.5 times, 0.6 times, 0.7 times, 0.8 times, 0.9 times, or 1 times, but is not limited to these. With this configuration, the cutting radii of the first blade 510 and the second blade 520 are different. The first blade 510 has a relatively smaller radial dimension along the cutter shaft, and its cutting area is located in the upper layer and close to the axis. The first blade 510 acts as a secondary blade and works with the second blade 520 for cutting. The second blade 520 has a relatively larger radial dimension along the cutter shaft, allowing it to fully utilize the space within the cup cavity 210. As the main blade, the second blade 520 can make full contact with the food, resulting in a large contact area and improved pulverization effect.

[0077] In one embodiment, with the axis of the cutter shaft 230 as the center, the maximum diameter φ3 of the circumference where the tip of the third cutter wing 530 is located is set to 0.3 to 0.8 times the maximum diameter φ2 of the circumference where the tip of the second cutter wing 520 is located. For example, it can be 0.3 times, 0.4 times, 0.5 times, 0.6 times, 0.7 times, or 0.8 times, but is not limited to these. With this configuration, the cutting radii of the third cutter wing 530 and the second cutter wing 520 are different. The radial dimension of the third cutter wing 530 along the cutter shaft is relatively small, and the cutting area is located in the lower layer and close to the axis. The third cutter wing 530 acts as a secondary cutter wing to cooperate with the second cutter wing 520 in cutting, while the radial dimension of the second cutter wing 520 is relatively large, allowing the second cutter wing 520 to make full use of the space within the cup cavity 210. As the main cutter wing, the second cutter wing 520 can make full contact with the food, ensuring that there are no dead angles in cutting and crushing.

[0078] Please refer to Figure 11 and Figure 12 , Figure 11 This is the front view of the third blade 53. Figure 12 This is the left view of the third blade 53.

[0079] In one embodiment, with the axis of the cutter shaft 230 as the center, the maximum diameter φ3 of the circumference of the tip of the third cutter blade 530 is 25mm to 45mm. For example, the maximum diameter φ3 can be set to 25mm, 30mm, 35mm, 40mm, or 45mm, but is not limited to these. This configuration allows for cutting and crushing of the lower layer of food material near the axis. Figure 11 In the embodiment shown, the third blade 53 includes two third blade wings 530. The two third blade wings 530 are spaced 180° apart and symmetrically arranged about the axis of the blade shaft 230. The tips of the two third blade wings 530 are located on the same circumference with the axis of the blade shaft 230 as the center. This makes the center of gravity of the third blade 53 coincide with the axis of the blade shaft 230, resulting in uniform mass distribution and better motion stability.

[0080] In one embodiment, the angle β between the third blade 530 and the axis O of the blade shaft 230 is 40° to 70°. For example, the angle β can be 40°, 45°, 50°, 55°, 60°, 65°, or 70°, but is not limited to these. The angle β determines the size of the turbulence radius of the third blade 53. The third blade 53 is positioned below the second blade 52 and acts as a secondary blade. Its main function is to turbulent and pulverize the lower layer of food in the cup cavity 210. The range of values ​​for the angle β allows the cutting diameter of the third blade 53 to be within a suitable range.

[0081] Please refer to Figures 13 to 15 , Figure 13 This is a front view of one embodiment of the second blade 52. Figure 14 yesFigure 13 The top view of the second blade 52 shown in the figure. Figure 15 yes Figure 13 The left view of the second blade 52 shown in the figure.

[0082] In one embodiment, there are an even number of second blades 520, and at least two of the second blades 520 are flat blades 5201 that are not bent. The flat blades 5201 are horizontal and have a larger radial dimension of the blade, which increases the contact area between the flat blades 5201 and the food, making full use of the space of the cup cavity 210 and resulting in a better crushing effect.

[0083] At least two of the aforementioned flat blade wings 5201 include a first flat blade 5201a and a second flat blade 5201b, wherein the first flat blade 5201a and the second flat blade 5201b are spaced 180° apart and are symmetrical about the axis of the cutter shaft 230. This arrangement results in the first flat blade 5201a and the second flat blade 5201b being relatively distributed circumferentially around the cutter shaft, leading to uniform mass distribution and good motion stability.

[0084] In one embodiment, such as Figure 13 As shown, the flat blade 5201 includes an arc-shaped cutting edge 52010, the radius R of which is 15mm to 40mm. Furthermore, with the axis of the blade shaft 230 as the center, the maximum diameter φ4 of the flat blade 5201 is set to 55mm to 80mm. This configuration allows the flat blade 5201 to be flat and the cutting edge 52010 to extend in an arc, which helps to increase the length of the cutting edge 52010, thereby increasing the contact area with the food. For example, the radius R can be set to 15mm, 20mm, 25mm, 30mm, 35mm, or 40mm, but is not limited to these.

[0085] In one embodiment, there are multiple and an even number of second blades 520, and at least two of the second blades 520 are configured as downward-bent blades 5202. The bent blades 5202 can better turbulentize the feed, causing the feed to continuously generate vortices, thus allowing the feed to be cut and mixed simultaneously, ensuring that there are no dead angles in cutting and crushing.

[0086] In this embodiment, at least two bent blade wings 5202 include a first bent blade wing 5202a and a second bent blade wing 5202b. The first bent blade wing 5202a and the second bent blade wing 5202b are arranged at a distance of 180° and are symmetrical about the axis of the blade shaft 230.

[0087] In one embodiment, such as Figure 14As shown, the folding blade 5202 includes a first folding blade 52021 and a second folding blade 52022 that are connected. In the radial direction of the blade shaft 230, the first folding blade 52021 is closer to the blade shaft 230 than the second folding blade 52022, and the bending direction of the first folding blade 52021 is opposite to that of the second folding blade 52022. This configuration ensures that the folding blade 5202 bends at at least two locations, and the cutting edge bends accordingly. This facilitates convection between the upper and lower layers of food, resulting in better mixing and cutting of the food.

[0088] In this embodiment, the first bending wing 52021 bends away from the first blade 51, and the second bending wing 52022 bends towards the first blade 51. This configuration allows the turbulence area of ​​the bending blade wing 5202 to be closer to the bottom of the cup cavity 210, which is more conducive to the flow of food at the bottom of the cup cavity 210 and can prevent scorching. Of course, in some other embodiments, the first bending wing 52021 may bend towards the first blade 51, and the second bending wing 52022 may bend away from the first blade 51.

[0089] In an alternative embodiment, the angle γ1 between the first bending wing 52021 and the axis of the cutter shaft 230 is 110° to 130°. For example, the angle γ1 can be 110°, 115°, 120°, 125°, or 130°, but is not limited thereto. The angle γ2 between the second bending wing 52022 and the axis of the cutter shaft 230 is 90° to 110°. For example, the angle γ2 can be 90°, 95°, 100°, 105°, or 110°, but is not limited thereto. With this configuration, the bending wing 5202 forms a moderate bend at at least two locations, which ensures a large turbulence radius for the bending wing 5202 and effectively achieves convection between the upper and lower layers of food.

[0090] Please refer to Figures 16 to 17 , Figure 16 for Figure 10 The front view of the cutter head 231 is shown in the figure. Figure 17 for Figure 16 Top view of the cutter head 231.

The first, second, and third flat blades 5201a, 5201b, and 5201c are evenly distributed circumferentially along the blade axis 230. The maximum diameter φ5 of the circumference of the blade tips of the first, second, and third flat blades 5201a, 5201b, and 5201c is 55mm to 58mm. This arrangement, with at least three flat blades 5201, increases the number of blades and their radial dimensions, thereby increasing the contact area with the food. For example, the maximum diameter φ5 can be 55mm, 56mm, 57mm, or 58mm, but is not limited to these.

[0092] exist Figure 17 In the embodiment shown, the first flat blade 5201a, the second flat blade 5201b, and the third flat blade 5201c are symmetrical about the axis of the blade shaft 230.

This makes the upper and lower blades more dispersed, resulting in better cutting and crushing effects.

For example, the maximum diameter φ2 can be 0.5, 0.6, 0.7, 0.8, 0.9, or 1 times, but is not limited to these. For example, the maximum diameter φ3 can be 0.3, 0.4, 0.5, 0.6, 0.7, or 0.8 times, but is not limited to these.

[0097] It should be noted that the number of first blades 510 can be one or five, and the number of second blades 520 can be one or five. It should also be explained that the angle between two adjacent second blades 520 can be understood as the angle between the axis of the blade shaft 230 and the two lines connecting the tips of the two adjacent second blades 520. The angle between two adjacent first blades 510 has the same meaning and will not be repeated here.

The cutting edge of the second cutting wing 520 is arc-shaped, and the radius of the circumference is set to 25mm to 40mm, for example, 25mm, 30mm, 35mm, or 40mm, but not limited to this.
