[0015] Optionally, the housing includes an upper cover and a lower cover, which together form a receiving space for housing the brushless motor.

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.

[0038] 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.

[0039] This application provides a food processor 100, which includes a base 10 and a blending cup 20 assembled to the base 10. The blending cup 20 is detachably assembled to the base 10, but is not limited thereto.

[0040] Please refer to Figure 2 and Figure 3 , Figure 2 for Figure 1 An exploded view of the base 10 shown in the figure. Figure 3 for Figure 1 The cross-sectional view of the base 10 shown in the figure.

[0041] The base 10 includes a housing 101 and a brushless motor 102, the brushless motor 102 being housed within the housing 101. Figure 2 In the illustrated embodiment, the outer casing 101 includes a separate upper cover 1010 and a bottom shell 1012, which together form a receiving space. The brushless motor 102 is housed within this receiving space and can be fixed with screws, but is not limited to this. The upper cover 1010 has a rotor hole 10100 for the rotor 1020 of the brushless motor 102 to extend out. A connector 103 can be mounted on the top of the rotor 1020 for transmission connection with the blade assembly in the mixing cup 20. The upper cover 1010 also includes a positioning part 10102 for mounting with the mixing cup 20, ensuring the installation position of the mixing cup 20. The base 10 also includes a control component 104 housed within the outer casing 101, arranged side-by-side with the brushless motor 102.

[0042] The brushless motor 102 is connected to the housing 101 and is relatively fixed to the housing 101 in the axial direction of the rotor 1020. The housing 101 also includes a positioning structure 1014 that is centrally positioned with the brushless motor 102.

[0043] As described above, the brushless motor 102 is directly mounted on the housing 101 without the need for a motor bracket bridge, thus achieving axial fixation of the brushless motor 102. Furthermore, the housing 101 includes a positioning structure 1014, which is centered with the brushless motor 102, making the installation position of the brushless motor 102 more accurate. This satisfies the installation requirements of the brushless motor 102 while saving space, reducing the size of the base 10. The installation method between the brushless motor 102 and the housing 101 is not limited, including but not limited to screw connections.

[0044] Please refer to Figure 4 and Figure 5 , Figure 4 This is an exploded view of the brushless motor 102. Figure 5 This is an internal view of the top cover 1010 of the outer casing 101.

[0045] The brushless motor 102 also includes a stator 1022 disposed outside the rotor 1020. The stator 1022 is arranged around the rotor 1020 and is coaxial with the rotor 1020. The brushless motor 102 can be an ultra-thin brushless motor, which further reduces the height of the brushless motor 102 and, consequently, further reduces the height of the frame 10.

[0046] In one embodiment, the brushless motor 102 is connected to the upper cover 1010 and axially fixed to it. The positioning structure 1014 includes a stator positioning structure 1014a disposed on the upper cover 1010, which is centrally positioned with the stator 1022. Thus, the brushless motor 102 is connected to the upper cover 1010 and centrally positioned with it, ensuring accurate installation of the brushless motor 102. Figure 5 In the illustrated embodiment, the stator positioning structure 1014a includes stator positioning ribs arranged around the stator 1022, coaxially with the stator 1022, thus achieving the positioning of the brushless motor 102. This stator positioning rib structure is simple, easy to implement, and provides reliable positioning. The stator positioning ribs are generally annular and continuously arranged. In other embodiments, the stator positioning structure 1014a may be multiple support structures distributed on the same circumference.

[0047] In an alternative embodiment, the stator positioning rib can be integrated with the upper cover 1010, for example, by injection molding, to simplify the manufacturing process. Alternatively, the stator positioning rib can be separate from the upper cover 1010.

[0048] exist Figure 5 In the illustrated embodiment, the brushless motor 102 is connected to the stator positioning structure 1014a to achieve axial fixation between the brushless motor 102 and the upper cover 1010. Thus, the stator positioning structure 1014a serves as both a connecting structure and a positioning structure. The connection method between the brushless motor 102 and the stator positioning structure 1014a includes, but is not limited to, a detachable connection, making the connection more convenient. Specifically, the stator positioning structure 1014a is provided with a connecting hole 10140, the direction of which is consistent with the axial direction of the rotor 1020. The connecting hole 10140 allows screws 105 to be screwed into, pressing the brushless motor 102 onto the upper cover 1010, thereby axially fixing the brushless motor 102 to the upper cover 1010. The specific number of connecting holes 10140 is not limited; exemplarily, three connecting holes 10140 can be provided, spaced apart on the stator positioning ribs.

[0049] Please refer to Figure 6 , Figure 6 An interior view of yet another embodiment of housing 101.

[0050] exist Figure 6In the illustrated embodiment, the stator positioning structure 1014a is a segmented stator positioning rib, that is, the stator positioning rib is a multi-segmented arc-shaped rib, with each arc-shaped rib located on the same circumference. In this embodiment, the connecting hole 10140 can be provided on each arc-shaped rib.

[0051] Please refer to Figure 7 and Figure 8 , Figure 7 This is a cross-sectional view of another embodiment of the base 10. Figure 8 for Figure 7 The interior view of the top cover 1010 is shown in the figure.

[0052] exist Figure 7 In the illustrated embodiment, the brushless motor 102 is connected to the upper cover 1010. The positioning structure 1014 further includes a rotor positioning structure 1014b, which is centered with the rotor 1020. This centered positioning of the upper cover 1010 and the rotor 1020 ensures alignment between the rotor 1020 and the rotor hole 10100, reduces rotor vibration, and improves the stability of the rotor 1020 during rotation.

[0053] The rotor positioning structure 1014b includes rotor positioning ribs surrounding the rotor 1020, which are coaxial with the rotor 1020. This rotor positioning rib structure is simple and easy to implement. For example, the rotor positioning ribs can be integrally formed with the upper cover 1010, such as through injection molding, to simplify the manufacturing process, but it is not limited to this. Furthermore, the rotor positioning structure 1014b can also correct the concentricity of the stator 1022 and the rotor 1020, eliminating assembly errors during the assembly of the brushless motor 102 and improving concentricity.

[0054] In an alternative embodiment, the brushless motor 102 is connected to the upper cover 1010. The upper cover 1010 is provided with a stator positioning structure 1014a and a rotor positioning structure 1014b. The stator positioning structure 1014a and the rotor positioning structure 1014b are coaxially arranged and integrally formed with the upper cover 1010. In this way, the rotor 1020 and the stator 1022 of the brushless motor 102 are both fixed and positioned by the upper cover 1010, resulting in a short assembly dimension chain and high concentricity, which is beneficial to motor noise reduction.

[0055] Please refer to Figures 9 to 11 , Figure 9 This is a cross-sectional view of another embodiment of the base 10. Figure 10 This is a schematic diagram of the brushless motor 102 mounted on the bottom housing 1012. Figure 11 This is a schematic diagram of the bottom shell 1012.

[0056] The brushless motor 102 is connected to the base housing 1012 and axially fixed to it. The positioning structure 1014 includes a stator positioning structure 1014a disposed on the base housing 1012, which is centrally positioned with the stator 1022. Thus, the brushless motor 102 is connected to the base housing 1012 and centrally positioned with it, ensuring accurate installation of the brushless motor 102. Figure 10 In the illustrated embodiment, the stator positioning structure 1014a includes a stator positioning rib surrounding the stator 1022. This stator positioning rib is coaxially arranged with the stator 1022, thus achieving center positioning of the brushless motor 102. This stator positioning rib structure is simple, easy to implement, and provides reliable positioning. The stator positioning rib is approximately annular and continuously arranged.

[0057] In an alternative embodiment, the stator positioning ribs can be integrated with the bottom shell 1012, for example, by injection molding, to simplify the manufacturing process. Alternatively, the stator positioning ribs can be separate from the bottom shell 1012.

[0058] exist Figure 10 In the illustrated embodiment, the brushless motor 102 is connected to the stator positioning structure 1014a. The connection method includes, but is not limited to, a detachable connection. The stator positioning structure 1014a serves as both a connection structure and a positioning structure. Specifically, the stator positioning structure 1014a has a connecting hole 10140. The direction of the connecting hole 10140 is consistent with the axial direction of the rotor 1020. The connecting hole 10140 is into which a screw 105 is screwed to press the brushless motor 102 onto the bottom shell 1012, thereby axially fixing the brushless motor 102 to the bottom shell 1012. The specific number of connecting holes 10140 is not limited. For example, three connecting holes 10140 can be provided, spaced apart on the stator positioning ribs.

[0059] exist Figure 11 In the illustrated embodiment, the rotor positioning ribs are circular and extend continuously. In other embodiments, the rotor positioning ribs may be segmented, with each segment located on the same circumference and surrounding the stator 1022.

[0060] Please refer to Figures 12 to 14 , Figure 12 This is another sectional view of the base 10. Figure 13 This is a schematic diagram of the assembly of the upper cover 1010 and the brushless motor 102. Figure 14 This is a schematic diagram of the bottom shell 1012.

[0061] In one embodiment, the brushless motor 102 is clamped and fixed between the upper cover 1010 and the bottom shell 1012 without the need for connectors, thereby simplifying the connection structure and improving assembly efficiency. The brushless motor 102 is jointly fixed by the upper cover 1010 and the bottom shell 1012. Specifically, the bottom shell 1012 is provided with a stator positioning structure 1014a, which is configured as a stator positioning rib surrounding the stator 1022. The inner surface of the stator positioning rib has a stepped surface 10142. A groove is formed on the side of the upper cover 1010 facing the bottom shell 1012. The bottom 10104 of the groove presses against the brushless motor 102, and the stepped surface 10142 supports the motor 102, thus clamping and fixing the brushless motor 102 between the bottom 10104 and the stepped surface 10142.

[0062] exist Figure 14 In the embodiment shown, the bottom shell 1012 includes a stator positioning structure 1014a, and the stator 1022 of the motor 102 is positioned by the stator positioning structure 1014a.
