Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0035] Please refer to Figure 1 and Figure 2 , Figure 1 An exploded view of the cup assembly 20 shown for an exemplary embodiment of this application. Figure 2 for Figure 1 The image shows a partial structural cross-section of the cup assembly 20.
[0036] This application provides a food processor 100, which includes a main unit 10 and a cup assembly 20. The cup assembly 20 is mounted on the main unit 10. For example, the cup assembly 20 may be mounted on the top of the main unit 10.
[0037] The main unit 10 includes a main unit housing 11 and a motor bracket 12 and a motor 13 housed within the main unit housing 11. The motor 13 is fixedly connected to the motor bracket 12. The motor shaft 130 of the motor 13 extends from the top cover 110 of the main unit housing 11.
[0038] The cup assembly 20 includes a cup body 21, a cup lid 22, and a stirring assembly 23. The cup body 21 forms a cup cavity 210, and the cup lid 22 covers the top of the cup body 21, sealing the cup cavity 210. The cup body 21 also has a handle 211. The stirring assembly 23 is rotatably mounted on the cup bottom 212 at the bottom of the cup body 21, and the cup bottom 212 can be configured as a heating plate. The stirring assembly 23 includes a blade shaft 230 and blades 231. The blade shaft 230 is drivenly connected to a motor shaft 130, and the blades 231 are located inside the cup cavity 210 for crushing and agitating food ingredients.
[0039] Please refer to Figures 3 to 5 , Figure 3 A front view of the stirring assembly 23 shown in an exemplary embodiment. Figure 4 yes Figure 3 The top view of the stirring assembly 23 shown in the figure. Figure 5 yes Figure 3 The left view of the stirring assembly 23 shown in the figure.
[0040] The mixing assembly 23 includes a blade shaft 230 and a lower blade 30. The lower blade 30 is fixed relative to the blade shaft 230, and the fixing method is not limited. The lower blade 30 is positioned closest to the bottom of the cup cavity, that is, the lower blade 30 is located at the bottom of the blade shaft 230. In this application, "upper" and "lower" refer to the orientation of the food processor 100 during operation.
[0041] The lower blade 30 includes a first blade 31, a second blade 32, and a third blade 33. The first blade 31 and the second blade 32 are aligned along a first direction parallel to the radial direction of the blade axis. Figure 4 In the X-direction, the first blade 31 and the second blade 32 are located on the same plane, which is perpendicular to the blade shaft 230. That is, the first blade 31 and the second blade 32 are configured as planar blades. Furthermore, the first cutting edge 310 of the first blade 31 and the second cutting edge 320 of the second blade 32 both face the bottom of the cup cavity. Here, "cutting edge" refers to the side surface of the first blade 31 and the second blade 32 that forms the cutting edge. Taking the first blade 31 as an example, the side of the first blade 31 facing the bottom of the cup cavity has a chamfered structure, and this chamfered structure is located on the first cutting edge 310. The third blade 33 is located between the first blade 31 and the second blade 32 and is configured to bend towards the bottom of the cup cavity, with the third cutting edge 330 of the third blade 33 facing away from the bottom of the cup cavity.
[0042] According to the above description, the first blade 31 and the second blade 32 are arranged as planar blades, and the blade faces of the first blade 31 and the second blade 32 both face the bottom of the cup cavity. When stirring, the stirring vortex generated by the first blade 31 and the second blade 32 has a large downward air pressure, and the vortex impacts the bottom of the cup cavity, so that the bottom is not easily pasted. At the same time, the third blade 33 is bent towards the bottom of the cup cavity, and the blade face of the third blade 33 faces away from the bottom of the cup cavity. This makes the stirring vortex generated by the third blade 33 counteract the stirring vortex generated by the first blade 31 and the second blade 32, thereby improving the stirring effect without increasing the stirring power of the motor.
[0043] In one embodiment, the lower blade 30 further comprises a fourth blade 34, the fourth blade 34 is opposite to the third blade 33 along a second direction (Y direction in the figure) parallel to the radial direction of the blade shaft, and the second direction is different from the first direction. For example, the second direction can be perpendicular to the first direction, or can be crossed at an angle less than 90°. The fourth blade 34 is arranged to be bent towards the bottom of the cup cavity, and the fourth blade face 340 of the fourth blade 34 is arranged to face away from the bottom of the cup cavity. In this way, the stirring vortex generated by the fourth blade 34 when stirring also counteracts the stirring vortex generated by the first blade 31 and the second blade 32, which can further improve the stirring effect. Figure 4 In one embodiment, the distance between the blade tip of any one of the first blade 31 and the second blade 32 and the axis of the blade shaft is greater than the distance between the blade tip of the third blade 33 and the axis of the blade shaft. As shown in FIGS. 1 and 2, the distance between the blade tip of the first blade 31 and the axis of the blade shaft is a, the distance between the blade tip of the second blade 32 and the axis of the blade shaft is b, the distance between the blade tip of the third blade 33 and the axis of the blade shaft is c, and the distance between the blade tip of the fourth blade 34 and the axis of the blade shaft is d. In this way, the stirring radius of the first blade 31 and the second blade 32 is relatively large, the downward air pressure formed by the stirring vortex is large, and the impact force of the vortex on the bottom of the cup cavity is large. The stirring radius of the third blade 33 and the fourth blade 34 is relatively small, which is used to cut the food materials around the blade shaft 230, and can also counteract the vortex at the center position of the first blade 31 and the second blade 32, thereby improving the crushing effect without affecting the downward vortex of the first blade 31 and the second blade 32.

[0045] In one embodiment, the blade tips of the first blade 31 and the second blade 32 are located on a first circle with the center of the circle being the center of the blade shaft. That is, the first blade 31 and the second blade 32 can be arranged at an interval of 180° and symmetrically with respect to the center of the blade shaft. In this way, the vortex is stable and the vortex noise is small when the blender is operated at a high speed. In one embodiment, the blade tips of the third blade 33 and the fourth blade 34 are located on a second circle with the center of the circle being the center of the blade shaft. The first blade 31 and the second blade 32 can be arranged at an interval of 180° and symmetrically with respect to the center of the blade shaft. In this way, the vortex is stable and the vortex noise is small when the blender is operated at a high speed. In this embodiment, the diameter of the first circle is greater than the diameter of the second circle, which allows the blades to cut the food materials within the respective radius.
[0046] In one embodiment, as shown in FIG. 4, the blender assembly 23 further includes an upper blade 40 fixed relative to the blade shaft. The upper blade 40 is configured to be farther away from the bottom of the cup cavity than the lower blade 30, i.e., the upper blade 40 is located above the lower blade 30.

The third direction can be different from the first direction and the second direction. The fifth blade 41 and the sixth blade 42 are configured to be bent away from the bottom of the cup cavity. Due to the bending of the fifth blade 41 and the sixth blade 42, the blade portions of the fifth blade 41 and the sixth blade 42 are inclined upward and toward the outside of the radial direction of the blade shaft. The cutting vortex of the fifth blade 41 and the sixth blade 42 intersects with the stirring vortex of the lower blade 30, and the stirring effect is better. In this embodiment, the fifth blade face 410 of the fifth blade 41 and the sixth blade face 420 of the sixth blade 42 both face the bottom of the cup cavity. Figure 3 Figure 4 In one embodiment, as shown in FIG. 4, the blender assembly 23 further includes an upper blade 40 fixed relative to the blade shaft.

The third direction can be different from the first direction and the second direction. The fifth blade 41 and the sixth blade 42 are configured to be bent away from the bottom of the cup cavity. Due to the bending of the fifth blade 41 and the sixth blade 42, the blade portions of the fifth blade 41 and the sixth blade 42 are inclined upward and toward the outside of the radial direction of the blade shaft. The cutting vortex of the fifth blade 41 and the sixth blade 42 intersects with the stirring vortex of the lower blade 30, and the stirring effect is better. In this embodiment, the fifth blade face 410 of the fifth blade 41 and the sixth blade face 420 of the sixth blade 42 both face the bottom of the cup cavity. Figure 4 In one embodiment, the upper blade 40 further includes a seventh blade 43 and an eighth blade 44 arranged opposite to each other in a fourth direction (S direction in FIG. 4) parallel to the radial direction of the blade shaft. The fourth direction can be different from the third direction, and can also be different from the first direction and the second direction. The seventh blade 43 and the eighth blade 44 are located in the same plane, and the plane is perpendicular to the blade shaft 230. That is, the seventh blade 43 and the eighth blade 44 are also arranged as planar blades. The seventh blade 43 and the eighth blade 44 are used to cut the food materials located above the first blade 31 and the second blade 32 and between the fifth blade 41 and the sixth blade 42, so as to enhance the crushing effect.
[0047] Figure 4 In one embodiment, as shown in FIG. 4, the blender assembly 23 further includes an upper blade 40 fixed relative to the blade shaft. The upper blade 40 is configured to be farther away from the bottom of the cup cavity than the lower blade 30, i.e., the upper blade 40 is located above the lower blade 30. The upper blade 40 includes a fifth blade 41 and a sixth blade 42 arranged opposite to each other in a third direction (Z direction in FIG. 4) parallel to the radial direction of the blade shaft. The third direction can be different from the first direction and the second direction. The fifth blade 41 and the sixth blade 42 are configured to be bent away from the bottom of the cup cavity. Due to the bending of the fifth blade 41 and the sixth blade 42, the blade portions of the fifth blade 41 and the sixth blade 42 are inclined upward and toward the outside of the radial direction of the blade shaft. The cutting vortex of the fifth blade 41 and the sixth blade 42 intersects with the stirring vortex of the lower blade 30, and the stirring effect is better. In this embodiment, the fifth blade face 410 of the fifth blade 41 and the sixth blade face 420 of the sixth blade 42 both face the bottom of the cup cavity.
[0048] In one embodiment, as shown in FIG. 4, the blender assembly 23 further includes an upper blade 40 fixed relative to the blade shaft. The upper blade 40 is configured to be farther away from the bottom of the cup cavity than the lower blade 30, i.e., the upper blade 40 is located above the lower blade 30. The upper blade 40 includes a fifth blade 41 and a sixth blade 42 arranged opposite to each other in a third direction (Z direction in FIG. 4) parallel to the radial direction of the blade shaft. The third direction can be different from the first direction and the second direction. The fifth blade 41 and the sixth blade 42 are configured to be bent away from the bottom of the cup cavity. Due to the bending of the fifth blade 41 and the sixth blade 42, the blade portions of the fifth blade 41 and the sixth blade 42 are inclined upward and toward the outside of the radial direction of the blade shaft. The cutting vortex of the fifth blade 41 and the sixth blade 42 intersects with the stirring vortex of the lower blade 30, and the stirring effect is better. In this embodiment, the fifth blade face 410 of the fifth blade 41 and the sixth blade face 420 of the sixth blade 42 both face the bottom of the cup cavity. Figure 5 As shown, the seventh blade face 430 of the seventh blade 43 and the blade face 440 of the eighth blade 44 are configured to face the bottom of the cup cavity. In this way, the cutting vortex of the seventh blade 43 and the eighth blade 44 does not affect the cutting vortex of each blade of the lower blade 30.
[0049] In one embodiment, the blade tip of the fifth blade 41 and the sixth blade 42 are located on a third circle with the center of the circle being the center of the blade shaft, and the blade tip of the seventh blade 43 and the eighth blade 44 are located on a fourth circle with the center of the circle being the center of the blade shaft. In this way, the fifth blade 41 and the sixth blade 42 are symmetrical about the center of the blade shaft, and the seventh blade 43 and the eighth blade 44 are symmetrical about the center of the blade shaft, so that the vortex is stable and the vortex noise is small when the high-speed stirring. Among them, the diameter of the circle on which the blade tip of the fifth blade 41 and the sixth blade 42 is located is smaller than the diameter of the circle on which the blade tip of the seventh blade 43 and the eighth blade 44 is located. In this way, the stirring radius of each pair of blades can also be different, which is beneficial to the crushing and stirring of food materials in different areas.
[0050] Please refer to Figure 6 , Figure 6 is a top view of the cup assembly 20 after the cup cover 22 is removed.

The distance between each circle and the single edge of the cup cavity bottom edge 213 can be set to be between 10mm and 30mm. That is, the first circle A1 with the largest diameter is spaced apart from the cup cavity bottom edge 213 by at least 10mm, the third circle A3 with the smallest diameter is spaced apart from the cup cavity bottom edge 213 by at least 30mm, and the second circle A2 and the fourth circle A4 are spaced apart from the cup cavity bottom edge 213 by a distance selected from between 10mm and 30mm.

In this way, the stirring vortex of the first blade 31 and the second blade 32 can impact the cup cavity bottom 2100, avoiding paste bottom, and also reserving a proper gap to avoid small food particles from sticking to the blades.
[0054] In one embodiment, the third blade 33 and the fourth blade 34 are bent towards the cup cavity bottom 2100, and the axial distance between the blade tips of the third blade 33 and the fourth blade 34 and the cup cavity bottom 2100 is H2, 2mm < H2 < 20mm.
