Description

Technical Field

[0001] This application relates to small household appliances, and in particular to food processors. Background Technology

[0002] The food processor includes a blending cup assembly and a base. The base includes a mounting cavity. The blending cup assembly is assembled into the mounting cavity. The base includes a power cord and a drive plate. The drive plate is equipped with high-voltage electrical components. The high-voltage electrical components are connected to the power cord.

[0003] Technicians have discovered that in existing food processors, high-voltage electrical components are located too close to the operating area and too close to the consumer, posing a safety hazard. Utility Model Content

[0004] The purpose of this application is to disclose a food processor. The high-voltage electrical components of the food processor are located far from the consumer, which helps to reduce safety hazards.

[0005] This application discloses a food processor. The food processor includes a blending cup assembly, a base, a drive plate, and a power cord. The base has a mounting cavity; the blending cup assembly is assembled into the mounting cavity; the mounting cavity includes a side cavity wall, which is surrounded by a first cavity wall and a second cavity wall; the drive plate is located inside the base and includes a drive plate end adjacent to the first cavity wall; a high-voltage electrical component is disposed at the drive plate end, and the power cord is located on the side of the second cavity wall and connected to the high-voltage electrical component.

[0006] As described above, the side walls of the mounting cavity are formed by a first cavity wall and a second cavity wall. The end of the drive plate is adjacent to the first cavity wall and is equipped with a high-voltage electrical component. The power cord is located on the side of the second cavity wall and connected to the high-voltage electrical component. In this way, the high-voltage electrical component and the power cord are relatively close. On the one hand, given the fixed length of the base, the aforementioned close proximity allows the high-voltage electrical component to be further away from the consumer, which helps reduce safety hazards. On the other hand, the aforementioned close proximity also facilitates wiring between the high-voltage electrical component and the power cord (for example, plugging the power cord into the high-voltage electrical component) and also facilitates wiring between the high-voltage electrical component and the second coupler.

[0007] In some embodiments, the base includes a mounting seat for providing the mounting cavity, the end of the drive plate includes a notch, a portion of the projection of the mounting seat in the horizontal plane lies within the projection of the notch in the horizontal plane, and the mounting seat and the drive plate are completely offset in a depth direction perpendicular to the mounting cavity; and / or, the high-voltage device is provided at the end of the sidewall of the notch sidewall.

[0008] As described above, since a portion of the projection of the mounting base onto the horizontal plane lies within the projection of the notch onto the horizontal plane, and the drive plate and the mounting base are completely offset in the depth direction perpendicular to the mounting cavity, the notch in the drive plate can accommodate the mounting base, resulting in a smaller base length in the X direction and a smaller width in the Y direction compared to when the drive plate is located below the mounting base and the mounting base is not offset in the depth direction perpendicular to the mounting cavity. This reduces the height of the base in the depth direction of the mounting cavity (i.e., the Z direction), resulting in a lower base height in the Z direction. Because the high-voltage components are located at the end of the sidewall of the notch, they can be placed closer to the power lines, facilitating wiring and allowing for a smaller base size in the X, Y, and Z directions.

[0009] In some embodiments, the gap between the notch sidewall and the first cavity wall on the projection of the horizontal plane is g, where g ≥ 0.2 mm.

[0010] As described above, since g ≥ 0.2 mm, the requirements for driver board assembly are relatively low, making assembly easier.

[0011] In some embodiments, the base includes a receiving cavity for accommodating the drive plate, the drive plate being assembled to the top wall of the receiving cavity; and / or, the food processor includes an operation panel, the drive plate including an operation area and an end area, the end area including the end of the drive plate; the operation area is located below the operation panel, the operation area being farther from the mounting cavity than the end area; the operation area and the end area are spaced apart by a distance H, where H ≥ 8 mm.

[0012] As described above, since the drive plate is assembled with the top wall of the receiving cavity, no mounting structure is needed between the drive plate and the bottom wall of the receiving cavity. Therefore, the distance between the drive plate and the bottom wall of the receiving cavity is small, which helps to reduce the height of the base along the depth direction of the mounting cavity. Because the operating area and the end area are spaced apart, and the end area includes the end of the drive plate, where the high-voltage components are located, when q≥8mm, the high-voltage components are far from the operating area, ensuring consumer safety.

[0013] In some embodiments, the blending cup assembly is detachably assembled into the mounting cavity and includes a cup base assembly, a blade assembly, a motor, and a first coupler. The motor is located within the cup base assembly and connected to the blade assembly; the first coupler is located within the cup base assembly; the blender includes a second coupler disposed at the bottom of the mounting cavity; the first coupler and the second coupler are connected. The first coupler is also located on the side of the motor; with the side where the cup base assembly is located as the bottom of each component, the bottom surface of the first coupler is not lower than the bottom surface of the motor; or, the blending cup assembly includes a heating plate assembly, the heating plate assembly includes a heating plate and a heating element, the blade assembly is assembled to the heating plate, the heating element includes a cold end, and the first coupler is located below the cold end.

[0014] As described above, since the first coupler is located on the side of the motor and its bottom surface is not lower than the bottom surface of the motor, the height of the cup holder assembly does not include the height of the first coupler, resulting in a lower cup holder assembly height. Because the cold end includes a terminal block, and the first coupler is located below the cold end, it facilitates wiring between the heating plate and the first coupler. Furthermore, since the temperature of the cold end is typically lower than that of the hot end, the first coupler's location below the cold end allows it to avoid relatively high-temperature areas. Therefore, this design reduces heat transfer from the heating plate assembly to the first coupler.

[0015] In some embodiments, the mixing cup assembly includes a mixing cup, a heating plate assembly, a motor, a blade assembly, and a cup holder assembly. The cup holder assembly is assembled with the mixing cup. The heating plate assembly and the mixing cup form a food processing cavity, including a heating plate and a heating element. The motor drives the blades of the blade assembly to rotate within the food processing cavity. The motor includes a front motor bracket and a motor shaft. The motor shaft is rotatably connected to the front motor bracket and is also connected to the blade assembly mounted on the heating plate assembly. The front motor bracket extends into the space enclosed by the heating plate and the heating element. The motor is assembled with the cup holder assembly.

[0016] As described above, the motor front bracket extends into the space enclosed by the heating plate and the heating element. Compared to the aforementioned implementation with a cover plate, this configuration reduces at least the thickness of the cover plate and the thickness of related connecting parts. Furthermore, compared to the implementation where the heating plate or heating element protrudes from the mounting post and the motor is mounted to the mounting post, this application does not require a mounting post. Therefore, the axial distance between the motor and the heating plate along the motor shaft is shorter, which helps reduce the axial height of the food processor along the motor shaft. In addition, assembling the motor with the cup assembly has several advantages. First, compared to assembling the motor with the mounting post of the heating plate or heating element, the motor not being assembled with the mounting post of the heating plate assembly helps prevent heat from the heating plate assembly from being transferred to the motor through the mounting post and corresponding screws. Second, since the motor is not assembled with the heating plate assembly, the motor's vibration will not cause vibration of the heating plate, thus preventing poor sealing between the heating plate assembly and the mixing cup (e.g., loose heating plate seals leading to poor sealing), and avoiding water leakage from the food processing chamber.

[0017] In some embodiments, the cup holder assembly includes a heating plate bracket, the heating plate bracket including a heat insulation portion, the heat insulation portion including a bracket opening axially extending through the motor shaft, the motor front bracket passing through the bracket opening of the heating plate bracket; the heat insulation portion is located between the heating element and the motor front bracket; or, the heat insulation portion is located between the heating element and the motor front bracket, and the heat insulation portion is located between the heating plate and the motor front bracket.

[0018] As described above, since the heat insulation part is located between the heating element and the front bracket of the motor; or, the heat insulation part is located between the heating element and the front bracket of the motor, and the heat insulation part is located between the heating plate and the front bracket of the motor, the heat insulation part can isolate heat, which helps to prevent excessive heat from the heating plate and the heating element from being transferred to the motor, and helps to prevent the motor temperature from being too high during operation.

[0019] In some embodiments, the motor front bracket includes a top connecting portion and a connecting frame connected to the top connecting portion. The top connecting portion is rotatably connected to the motor shaft; the distance between the connecting frame and the heating plate along the axial direction of the motor shaft gradually increases in the radial direction of the motor shaft toward the heating element.

[0020] As described above, since the axial distance between the connecting bracket and the heating plate along the motor shaft gradually increases along the direction from the motor shaft to the heating element, compared with the fact that the distance between the first connecting part and the heating plate is equal everywhere, this application ensures that the front bracket of the motor is farther away from the heating plate while reducing the distance between the motor and the heating plate. This helps to avoid excessive heat transfer from the heating plate and the heating element to the motor and helps to avoid the motor temperature from getting too high during operation.

[0021] In some embodiments, the motor front bracket includes at least one of the following features:

[0022] a) The connecting frame includes a support sidewall, which is formed in the shape of a regular frustum or a frustum pyramid.

[0023] (b) The heating element includes a bottom facing away from the heating plate; the projection of the motor front bracket on the heating plate is located within the annular area enclosed by the projection of the bottom of the heating element on the heating plate, or the motor includes a motor housing, and the projections of the front end of the motor front bracket and the front end of the motor housing on the heating plate are located within the annular area enclosed by the projection of the bottom of the heating element on the heating plate. With the above configuration, since at least the projection of the front end of the motor front bracket on the heating plate is located within the annular area enclosed by the projection of the bottom of the heating element on the heating plate, the motor can avoid the heating element and approach the heating plate, which helps to reduce the distance between the motor and the heating plate, and consequently, helps to reduce the axial height of the food processor along the motor shaft. Of course, this feature, combined with the aforementioned gradual increase, not only helps to reduce the axial height of the food processor along the motor shaft, but also helps to avoid excessive heat transfer from the heating plate and heating element to the motor.

[0024] c) The heating plate includes a plate body and a protrusion extending into the interior of the mixing cup, with the plate body surrounding the protrusion. The intersection of the connecting bracket and the top connecting portion is not lower than the plate body. The top connecting portion extends into the protrusion, and the protrusion includes a connecting hole. The blade assembly includes a blade shaft. The blade shaft and the motor shaft are connected through the connecting hole. As described above, since the protrusion extends into the interior of the mixing cup, and the intersection of the connecting bracket and the top connecting portion is not lower than the plate body, and the top connecting portion extends into the protrusion, this is more conducive to reducing the axial height of the food processor along the motor shaft. Furthermore, the extension of the top connecting portion into the protrusion can also help position the motor assembly, making motor assembly convenient.

[0025] d) The maximum distance d between the connecting bracket and the heating plate along the axial direction of the motor shaft is 5mm ≤ d ≤ 25mm. As described above, since 5mm ≤ d ≤ 25mm, the space enclosed by the motor front bracket, the heating plate, and the heating element is relatively large (for example, after assembling the motor and cup holder assembly, the space enclosed by the motor front bracket, heating plate, and heating element has no mounting structure, making the space larger). This provides a larger heat dissipation space, which is more conducive to preventing excessive heat transfer from the heating plate assembly to the motor, and helps to prevent the motor from overheating during operation. Furthermore, with 5mm ≤ d ≤ 25mm, it is also beneficial to reduce the height of the food processor along the axial direction of the motor shaft.

[0026] In some embodiments, the stirring cup assembly satisfies at least one of the following conditions:

[0027] The motor is a DC motor. The axial height of the motor along the motor shaft is L, 30mm≤L≤75mm; the diameter of the motor is w, w≤76.5mm; the load torque of the motor is T, 105N·m≤T≤135N·m; the no-load speed of the motor is V, 12000r / min≤V≤14500r / min; the load speed of the motor is v: 9000r / min≤v≤11000r / min; the height of the cup holder assembly along the axial direction of the motor shaft is k, k≤85mm.

[0028] As described above, if the motor or cup holder assembly meets any of the above conditions, it helps to ensure that the height of the motor or cup holder assembly is low. Consequently, the height of the mixing cup assembly along the axial direction of the motor shaft is low, which also helps to ensure that the height of the mixing cup assembly is low. When the mixing cup assembly and the base are detachably assembled, it also facilitates convenient handling of the mixing cup assembly by the consumer. Attached Figure Description

[0044] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0045] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. 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.

[0046] See Figure 1 , Figure 7 and Figure 9The food processor disclosed in this application includes a blending cup assembly 10 and a base 20. The blending cup assembly 10 and the base 20 are separate structures (detachable and assembleable). For example, when food needs to be processed using the food processor, the blending cup assembly 10 is assembled to the base 20. When the processed food needs to be poured out, the blending cup assembly 10 can be removed from the base 20. Alternatively, the blending cup assembly 10 and the base 20 can be an integrated structure. For example, regardless of whether food needs to be poured out of the blending cup 10, the blending cup assembly 10 and the base 20 are assembled as a single unit. Whether the blending cup assembly 10 and the base 20 are an integrated structure or separate structures, the food processor also includes a drive board 30 and a power cord 40.

[0047] See Figure 2 and Figure 4 The base 20 is provided with a mounting cavity 201. The shape of the mounting cavity 201 is determined by the shape of the cup holder assembly. The cup holder assembly of the stirring cup assembly 10 is typically circular; therefore, the mounting cavity 201 is also circular. The stirring cup assembly 10 is assembled into the mounting cavity 201. This assembly can be achieved by placing the stirring cup assembly 10 inside the mounting cavity 201, or by using a structure such as a positioning post. See also... Figure 2 and Figure 3 The side cavity wall of the mounting cavity 201 is formed by a first cavity wall 2011 and a second cavity wall 2012. See also Figure 2 and Figure 3 When the mounting cavity 201 is circular, the central angle corresponding to the first cavity wall 2011 is smaller than the central angle corresponding to the second cavity wall 2012. In other embodiments, the central angle corresponding to the first cavity wall 2011 may also be greater than or equal to the central angle corresponding to the second cavity wall 2012.

[0048] See Figure 4 and Figure 5 The drive board 30 is used to control the rotation of the motor 3, etc. When the food processor has a heating function, the food processor can achieve the heating function under the control of the drive board 30. Of course, the food processor may not have a heating function. The drive board 30 is located inside the base 20. See also... Figure 3 and Figure 5 The drive plate 30 includes a drive plate end 301. The drive plate end 301 is adjacent to the first cavity wall 2011, and this adjacency can be on the circumferential side of the mounting cavity 201. The circumferential adjacent gap is not limited to... Figure 3As shown in g, the drive plate end 301 can also be adjacent to the bottom wall of the mounting cavity 201, so that the distance between the drive plate end 301 and the bottom wall of the mounting cavity 201 meets safety regulations and other requirements. The drive plate end 301 is equipped with high-voltage electrical components (not shown in the figure). The power cable 40 is disposed on the base 20, located on the side of the second cavity wall 2012. The side can have a distance between the power cable 40 and the second cavity wall 2012.

[0049] As described above, since the side wall of the mounting cavity 201 is surrounded by the first cavity wall 2011 and the second cavity wall 2012, the end 301 of the drive plate is adjacent to the first cavity wall 2011 and is equipped with a high-voltage device. The power cord 40 is located on the side of the second cavity wall 2012 and is connected to the high-voltage device. In this way, the high-voltage device and the power cord 40 are relatively close. On the one hand, the length of the base is fixed, and the aforementioned close proximity will inevitably allow the high-voltage device to be further away from the consumer (more specifically, in conjunction with...). Figure 3 and Figure 6 Since the length of the base 20 along the X direction is fixed, when viewed in the X direction, the proximity of the high-voltage device to the power line 40 will inevitably keep the high-voltage device away from the operating area 302, which helps to reduce safety hazards. On the other hand, the aforementioned proximity also facilitates the wiring between the high-voltage device and the power line 40 (for example, plugging the power line into the high-voltage device), and also facilitates the wiring between the high-voltage device and the second coupler 60.

[0050] See Figure 3 and Figure 4 The base 20 includes a mounting seat 202 for providing the mounting cavity 201. The end of the drive plate 301 includes a notch 3011. The notch 3011 is located in... Figure 3 and Figure 4 The notch 3011 has two arc-shaped ends. In some embodiments, the notch 3011 may also be U-shaped when it has two sidewall ends 3012. In some embodiments, the notch 3011 may also be L-shaped, in which case the notch 3011 has only one sidewall end 3012. See also Figure 3 A portion of the projection of the mounting base 202 onto the horizontal plane lies within the projection of the notch 3011 onto the horizontal plane, and the drive plate 30 is completely offset from the mounting base 202 in a depth direction perpendicular to the mounting cavity 201.

[0051] As described above, since a portion of the projection of the mounting base 202 onto the horizontal plane lies within the projection of the notch 3011 onto the horizontal plane, and the drive plate 30 and the mounting base 202 are completely offset in the depth direction perpendicular to the mounting cavity 201, the notch in the drive plate 30 can accommodate the mounting base 202 compared to when the drive plate 30 does not have the notch. This results in a smaller length of the base 20 along the X-direction and a smaller width along the Y-direction. More specifically, see [link to relevant documentation]. Figure 3 Without the notch 3011, the drive plate 30 can only reach point A, for example, in the X direction. The base 20 can be reduced by a length of x, where x is the distance between the tangent of the mounting base 202 and the side of the drive plate 30, both of which are perpendicular to the X direction. Correspondingly, because a portion of the projection of the mounting base 202 onto the horizontal plane lies within the projection of the notch 3011 onto the horizontal plane, the width of the base 20 in the Y direction will not be equal to the sum of the width of the drive plate 30 and the width of the base 20, but only equal to the width of the base 20 itself. Therefore, the width of the base 20 in the Y direction is small.

[0052] Furthermore, the above-mentioned arrangement can also reduce the height of the base 20 along the depth direction of the mounting cavity 201. For more details, see [link to documentation]. Figure 2 and Figure 4 In some embodiments, the drive plate 30 is located below the mounting base 202 but not offset from the mounting base 202 in the depth direction perpendicular to the mounting cavity 201. To avoid signal interference (such as electrical clearance), a sufficient distance must be maintained between the drive plate 30 and the mounting base 202 in the Z direction, which makes the height of the base 20 relatively high. Compared with this embodiment, because the drive plate 30 and the mounting base 202 are completely offset in the depth direction perpendicular to the mounting cavity 201, the high-voltage components at the end of the drive plate 301 have no other components, so there is no need to consider the impact on the high-voltage components. Thus, the height of the base 20 in the Z direction is relatively low.

[0053] See Figure 2 and Figure 6 The high-voltage device is disposed at the sidewall end 3012 of the notch sidewall, and the sidewall end 3012 is located at the connection between the first cavity wall 2011 and the second cavity wall 2012. When there are two sidewall ends 3012, each sidewall end 3012 is provided with a high-voltage device, or only one sidewall end 3012 is provided with the high-voltage device.

[0054] As described above, the high-voltage device is provided at the end of the side wall 3012. The distance between the high-voltage device and the power line 40 is shorter, which makes wiring easier and allows the base 20 to be smaller in size along the X, Y and Z directions.

[0055] See Figure 3 On the projection of the horizontal plane, the gap between the notch sidewall and the first cavity wall 2011 is g, where g ≥ 0.2 mm. g can also be considered as the gap between the notch sidewall and the first cavity wall 2011 after the drive plate 30 and the base 20 are assembled.

[0056] With the above settings, since g≥0.2mm, the requirements for driver board assembly are relatively low, making assembly easier.

[0057] See Figure 3 and Figure 5 The food processor includes an operation panel 70. The drive plate 30 includes an operation area 302 and an end area 303, the end area 303 including the drive plate end 301. The operation area 302 is located below the operation panel 70. The operation area 302 is further away from the mounting cavity 201 than the end area 303. The operation area 302 and the end area 303 are spaced apart by a distance q, where q ≥ 8 mm.

[0058] As described above, since the operation area 302 and the end area 303 are spaced apart, and the end area 303 includes the drive board end 301, the drive board end 301 is provided with the high-voltage device. When q≥8mm, the high-voltage device is far away from the operation area 302, ensuring consumer safety.

[0059] See Figure 4 and Figure 5 The base 20 includes a receiving cavity 203 for accommodating the drive plate 30. The configuration of the receiving cavity 203 is not limited; for example, the upper shell 2033 and the lower shell 2034 of the base 20 are assembled to form the receiving cavity 203. The drive plate 30 is assembled with the top wall 2031 of the receiving cavity 203. The assembly method is not limited; for example, the top wall of the receiving cavity 203 is provided with a screw post 2032 extending towards the bottom wall. The screw passes through the drive plate 30 and locks with the screw post 3032, thereby assembling the drive plate 30 with the top wall 2031. The top wall 2031 is part of the upper shell 2033.

[0060] In some embodiments, the drive plate is assembled onto the mounting plate, and the mounting plate is then assembled onto the bottom wall of the receiving cavity. As described above, since the drive plate 30 is assembled with the top wall 2031 of the receiving cavity 203, no mounting structure is required between the drive plate 30 and the bottom wall of the receiving cavity 203 (for example, no mounting plate and corresponding structure are required). This reduces the height occupied by this part of the structure. Therefore, the distance t between the drive plate 30 and the bottom wall of the receiving cavity 203 is small, which helps to reduce the height of the base 20 along the Z direction (along the depth direction of the mounting cavity 201).

[0061] See Figure 7 and Figure 8The mixing cup assembly 10 is detachably assembled into the mounting cavity 201 and includes a mixing cup 1, a cup base assembly, a blade assembly 4, a motor 3, and a first coupler 8. The cup base assembly is assembled with the mixing cup 1. The motor 3 is located inside the cup base assembly and is connected to the blade assembly 4, driving the blades of the blade assembly 4 to rotate within the food processing cavity to process food. The first coupler 8 is located inside the cup base assembly. The food processor includes a coupler 60. The second coupler 60 is disposed at the bottom of the mounting cavity 201; when the mixing cup assembly 10 is assembled within the mounting cavity 201, the first coupler 8 and the second coupler 60 are connected. The first coupler 8 is also located on the side of the motor 3; with the side where the cup base assembly is located as the bottom of each component, the bottom surface 81 of the first coupler 8 is not lower than the bottom surface 39 of the motor 3. That is, the bottom surface 81 of the coupler is flush with or higher than the bottom surface of the motor. Figure 3 and Figure 4 It can be assumed that the bottom surface 81 of the coupler is flush with the bottom surface 39 of the motor.

[0062] In some implementations, the first coupler 8 is located below the motor 3 (below the first coupler 8), so that the height of the cup holder assembly includes the height of the first coupler 8.

[0063] As described above, since the first coupler 8 is located on the side of the motor 3 and the bottom surface 81 of the coupler is not lower than the bottom surface 39 of the motor 3, the height of the cup holder assembly does not include the height of the first coupler 8, and the height of the cup holder assembly is relatively low.

[0064] See Figure 8 The stirring cup assembly includes a heating plate assembly 2, which includes a heating plate 21 and a heating element 22. The blade assembly 4 is assembled on the heating plate 21. The heating element 22 includes a cold end 221 and a hot end. The first coupler 8 is located below the cold end 221.

[0065] As described above, since the cold end 221 includes a terminal block, the first coupler 8 is located below the cold end 221. This facilitates the connection between the heating plate 21 and the first coupler 8. Furthermore, since the temperature of the cold end 221 is usually lower than that of the hot end, the location of the first coupler 8 below the cold end 221 allows the first coupler 8 to avoid areas with relatively high temperatures. Therefore, the above design reduces the heat transfer from the heating plate assembly 2 to the first coupler 8.

[0066] See Figures 7 to 11The mixing cup assembly includes a mixing cup 1 and a cup holder assembly assembled with the mixing cup 1. The assembly method of the cup holder assembly with the mixing cup 1 is not limited; for example, the cup holder assembly includes a heating plate support 5. The heating plate support 5 and the mixing cup 1 are assembled via a snap-fit ​​structure or a threaded structure. The mixing cup assembly 10 also includes a heating plate assembly 2 that forms a food processing cavity with the mixing cup 1. The formation of the food processing cavity is not limited; for example, the heating plate assembly 2 includes a heating plate 21, a heating element 22, and a heating plate seal 23. After the heating plate support 5 is assembled with the mixing cup 1, the clamping portion 24 of the edge of the heating plate assembly 2 is clamped between the heating plate support 5 and the mixing cup 1, thus forming a cavity between the heating plate 21 and the mixing cup 1. Under the aforementioned clamping action, the heating plate seal 23 seals the cavity, thereby forming a food processing cavity between the heating plate assembly 2 and the mixing cup 1. The heating element 22 is used to heat the food in the food processing cavity and can be a heating tube. In some other embodiments, the cup holder assembly includes a cup holder 6. The heating plate assembly 2 is clamped between the cup holder 6 and the stirring cup 1, rather than between the heating plate support 5 and the stirring cup 1. In this case, the heating plate support 5 and the cup holder 6 are assembled.

[0067] The motor 3 includes a front motor bracket 32 ​​and a motor shaft 33. The motor shaft 33 is rotatably connected to the front motor bracket 32, and the rotatable connection method is not limited. For example, the front motor bracket 32 ​​includes a top connecting portion 321. The top connecting portion 321 includes a bearing mounting cavity, and a bearing 3211 is installed in the bearing mounting cavity. The motor shaft 33 passes through the bearing 3211 to achieve the rotatable connection. The motor shaft 33 is also connected to the blade assembly 4 installed on the heating plate assembly 2. The front motor bracket 32 ​​extending into the space 220 enclosed by the heating plate 21 and the heating element 22 includes: 1) only the front motor bracket 32 ​​extending into the space 220; 2) both the front motor bracket 32 ​​and the front end 311 of the outer shell extending into the space 220. The motor 3 is assembled with the cup holder assembly. For example, the cup holder assembly includes the heating plate bracket 5 and the cup holder 6. Motor 3 can be assembled with cup holder 6, or with heating plate bracket 5, or motor 3 can be assembled with both heating plate bracket 5 and cup holder 6, as follows: See Figure 10 and Figure 11 The heating plate bracket 5 includes a first mounting portion 52. (See also...) Figure 8 , Figures 10 to 13 The motor 3 includes a motor housing 31 and a rear motor support 34. The food processor includes connecting arms 35 circumferentially distributed on the motor 3. The connecting arms 35 can be connected to the motor housing 31, or to the rear motor support 34, or, see [link to other documentation] Figures 12 to 15The connecting arm 35 is connected to both the motor housing 31 and the motor rear bracket 34. The connection can be an integral part of the connecting arm 35 and the motor housing 31, or it can be assembled as a separate component onto the motor 3. The number of connecting arms 35 is not limited to four; it can be five, three, etc. The connecting arm 35 includes a second mounting portion 352. The cup holder 6 includes a third mounting portion 62. The third mounting portion 62, the second mounting portion 352, and the first mounting portion 52 are assembled together, and their assembly is not limited to the bolt and locking mechanism described later. The food processor also includes a shock absorber 7, located between the first mounting portion 52 and the second mounting portion 352, and between the second mounting portion 352 and the third mounting portion 62. After the bolt passes through the first mounting portion 52, the second mounting portion 352, and the third mounting portion 62, it is locked with the locking mechanism, thereby completing the assembly between the connecting arm 35, the cup holder 6, and the heating plate bracket 5, thus assembling the motor 3. As described above, since the shock absorber 7 is located between the first mounting part 52 and the second mounting part 352, and between the second mounting part 352 and the third mounting part 62, the shock absorber 7 is beneficial to reduce the vibration caused by the operation of the motor 3, for example, it is beneficial to reduce the noise caused by the vibration.

[0068] In the case where the cup holder assembly includes a heating plate bracket 5, the heating plate bracket 5 includes a bracket opening 50, such that the motor front bracket 32 ​​extends through the bracket opening 50 into the space 220 enclosed by the heating plate 21 and the heating element 22.

[0069] In some embodiments, the heating plate support 5 and the heating plate 21 form a cavity, and the heating element 22 is located within the cavity. In this embodiment, the heating plate support 5 includes a cover plate facing the heating plate 21 and used to form the cavity. The motor 3 is assembled on the cover plate and cannot extend into the cavity formed by the heating plate 21 and the heating element 22. Thus, the height between the motor and the heating plate includes at least the sum of the axial distance between the cover plate and the heating plate along the motor shaft, the thickness of the cover plate, and the thickness of the nut. This results in a large axial distance between the motor 3 and the heating plate 21 along the motor shaft 33, leading to a relatively high height of the food processor along the motor shaft 33, making it inconvenient for consumers to use. In other embodiments, a mounting post protrudes from the heating plate or heating element towards the motor, and the motor is connected to the mounting post. Considering motor stability, the distance between the mounting post and the heating plate is greater than the distance between the heating element and the heating plate. This embodiment also results in a relatively high height of the food processor along the motor shaft.

[0070] As described above, the motor front bracket 32 ​​extends into the space 220 formed by the heating plate 21 and the heating element 22. Compared with the aforementioned implementation with a cover plate, this configuration at least reduces the thickness of the cover plate and the thickness of the related connecting parts. Furthermore, compared to the implementation where the heating plate or heating element protrudes from the mounting post and the motor is mounted to the mounting post, this application does not require a mounting post. Therefore, the distance between the motor 3 and the heating plate 21 along the axial direction of the motor shaft 33 is shorter, which helps to reduce the height of the food processor along the axial direction of the motor shaft 33. In addition, the assembly of the motor 3 with the cup holder assembly has several advantages. First, compared to the installation of the motor 3 with the mounting post of the heating plate 21 or the heating element 22, the fact that the motor 3 is not assembled with the mounting post of the heating plate assembly 2 helps to prevent the heat from the heating plate assembly from being transferred to the motor through the mounting post and corresponding screws. Second, since the motor 3 is not assembled with the heating plate assembly 2, the vibration of the motor 3 will not cause the heating plate 21 to vibrate, thus preventing poor sealing between the heating plate assembly 2 and the mixing cup 1 (e.g., the heating plate seal 23 becoming loose and causing poor sealing), and avoiding water leakage from the food processing chamber.

[0071] The following describes some features of the assembly between the motor 3, the heating plate bracket 5, and the cup holder 6:

[0072] See Figure 10 and Figure 11 The first mounting portion 52 is columnar. The third mounting portion 62 is also columnar and has a positioning groove. The first mounting portion 52 passes through the second mounting portion 352 and is located within the positioning groove. Those skilled in the art will understand that when the first mounting portion 52 has a positioning groove, the third mounting portion 62 is located within the positioning groove. Screws are inserted into the third mounting portion 62, the second mounting portion 352, and the first mounting portion 52 to assemble the heating plate bracket 5, the cup holder 6, and the connecting arm 35 together. In other embodiments, the first mounting portion 52 has a positioning groove; in this case, the first mounting portion 52 may also pass through the second mounting portion 352, and the third mounting portion 62 may be located within the positioning groove. In the above embodiments, the first mounting portion 52 passes through the second mounting portion 352; in other embodiments, the third mounting portion 62 may also pass through the second mounting portion 352.

[0073] As described above, since one of the first mounting part 52 and the third mounting part 62 includes a positioning groove; the other of the first mounting part 52 and the third mounting part 62 passes through the second mounting part 352 and is located in the positioning groove, the assembly of the heating plate bracket 5, the cup holder 6 and the connecting arm 35 is simple and precise through this positioning.

[0074] See Figure 12 , Figure 13 and Figure 15The connecting arm 35 is provided with reinforcing ribs 355. The reinforcing ribs 355 are spaced apart in the width direction of the connecting arm 35. Although Figure 6 Only one reinforcing rib 355 perpendicular to the length direction of the connecting arm 35 is shown in the figure. Those skilled in the art will understand that the reinforcing rib 355 may also be spaced apart along the length direction of the connecting arm 35. In other embodiments, the reinforcing ribs 355 may be spaced apart only along the length direction of the connecting arm 35, or only along the width direction of the connecting arm 35. The figure shows that the length of the reinforcing rib 355 is equal to the length of the connecting arm 35, but the length of the reinforcing rib 355 may also be shorter than the length of the connecting arm 35.

[0075] As described above, by providing reinforcing ribs 355 on the connecting arm 35, and by providing reinforcing ribs 355 at intervals in the width direction and / or length direction of the connecting arm 35, the reinforcing ribs 355 can enhance the strength of the connecting arm 35, and can better assemble the motor 3 with the heating plate bracket 5 and the cup holder 6.

[0076] See Figure 14 Along the axial direction of the motor shaft 33, the sum of the height of the motor housing 31 and the height of the motor rear bracket 34 is F, and the height of the second mounting part 352 relative to the motor rear bracket 34 is f, where 1 / 2 ≤ f / F ≤ 1.

[0077] As described above, since 1 / 2≤f / F≤1, and considering the circumferential distribution of the connecting arm 35 in the motor 3, this ensures that the motor 3 is less prone to shaking during operation, making the motor 3 more stable.

[0078] The structure of the connecting arm 35 and the rear motor bracket 34 is described below:

[0079] See Figure 10 , Figures 12 to 15 The motor housing 31 forms a bottom opening. The motor rear bracket 34 covers the bottom opening. The connecting arms 35 (all or some of the connecting arms 35) include a first connecting arm 353 and a second connecting arm 354. The first connecting arm 353 extends along the motor rear bracket 34. The second connecting arm 354 contacts the motor housing 31 and extends axially along the motor shaft 33. The contact can be between the second connecting arm 354 and the outer surface of the motor housing 31, or it can be embedded within the motor housing 31. The second connecting arm 354 is connected to the second mounting portion 352. In some embodiments, both the motor rear bracket and the connecting arms are made of plastic.

[0080] As described above, the first connecting arm 353 extends along the rear motor bracket 34, and the second connecting arm 354 extends along the motor housing 31. In this way, the motor housing 31, the rear motor bracket 34, and the connecting arm bracket are easy to assemble. The structure of the connecting arm is combined with the fact that the rear motor bracket and the connecting arm are both made of plastic, which is easy to manufacture and has low cost.

[0081] See Figure 13 and Figure 15 The motor rear support 34 includes a flat support body 341 and a gathering portion 342 protruding from the support body 341. The gathering portion 342 can also be flat (as shown in the figure, a circular plate; the flatness can be understood as the support body 341 or the gathering portion including relatively parallel planes, such as cylinders, etc.). Of course, the gathering portion 342 can be small and not flat, as long as it does not significantly affect the height. The support body 341 can be circular or not, and its shape is determined by the shape of the bottom opening of the motor housing 31. The support body 341 covers the bottom opening. All connecting arms 35 converge at the gathering portion 342. In some embodiments, the gathering portion 342 is not part of the motor rear support 34; that is, the food processor includes a mounting frame, which includes the gathering portion 342 and multiple connecting arms 35, which converge at the gathering portion 342, and the motor rear support 34 is supported by the mounting frame.

[0082] As described above, since the motor rear bracket 34 includes a flat bracket body 341 and a gathering part 342, and the height of the motor rear bracket 34 is the sum of the thickness of the bracket body 341 and the height of the gathering part 342, the height is relatively low. Therefore, the assembly of this structure of the motor rear bracket 34 with the motor housing 31 also helps to reduce the height of the food processor along the axial direction of the motor shaft 33.

[0083] See Figure 8 and Figure 10 The heating plate bracket 5 includes a heat insulation portion 51, which has a bracket opening 50 extending axially through the motor shaft 33. The motor front bracket 32 ​​passes through the bracket opening 50 of the heating plate bracket 5. The heat insulation portion 51 is located between the heating element 22 and the motor front bracket 32; or, the heat insulation portion 51 is located between the heating element 22 and the motor front bracket 32, and the heat insulation portion 51 is located between the heating plate 21 and the motor front bracket 32.

[0084] As described above, since the heat insulation part 51 is located between the heating element 22 and the front bracket 32 ​​of the motor; or, the heat insulation part 51 is located between the heating element 22 and the front bracket 32 ​​of the motor, and the heat insulation part 51 is located between the heating plate 21 and the front bracket 32 ​​of the motor, the heat insulation part 51 can insulate heat, which helps to prevent excessive heat from the heating plate 21 and the heating element 22 from being transferred to the motor 3, and helps to prevent the motor 3 from overheating during operation.

[0085] See Figure 8 , Figure 9 , Figure 11 and Figure 14 The front bracket 32 ​​of the motor is not limited to, for example Figure 5 and Figure 7 The cover-like structure shown can be, for example, a tripod, a quadruped, or a frame structure. The motor front bracket 32 ​​includes a top connecting portion 321 and a connecting frame 322 connected to the top connecting portion 321. In some embodiments, the motor front bracket 32 ​​includes a bottom connecting portion 323. The bottom connecting portion 323 is the part of the motor front bracket 32 ​​used to connect to the motor housing, and its structure is not limited. When the motor front bracket 32 ​​includes a bottom connecting portion 323, the top and bottom ends of the connecting frame 322 are connected to the top connecting portion 321 and the bottom connecting portion 323, respectively. The top connecting portion 321 is rotatably connected to the motor shaft 33. The motor 3 includes a motor housing 31, and the front end 311 of the motor housing 31 is connected to the bottom connecting portion 323 to achieve the connection between the motor housing 31 and the motor front bracket 32. In other embodiments, the motor housing 31 and the motor front bracket 32 ​​are integrally formed to achieve the connection. Furthermore, the motor front bracket 32 ​​is not limited to being connected to the motor housing 31. Motor housing 31 Figures 7 to 10 as well as Figures 12 to 14 The outer casing is cylindrical with a continuous shaft. In this case, the front end 311 of the outer casing is the section connected to the bottom connecting part 323. Alternatively, the motor casing 31 can also be roughly U-shaped, in which case the front end 311 is the narrow part of the U-shape. In short, the length of the front end 311 of the outer casing is not limited and can be determined according to the installation requirements between the motor 3 and the heating plate assembly 2. The connection between the front end 311 of the outer casing and the bottom connecting part 323 can be achieved by clamping as described later, or by connecting with screws or other fasteners.

[0086] The distance between the connecting frame 322 and the heating plate 21 along the axial direction of the motor shaft 33 gradually increases in the radial direction of the motor shaft 33 toward the heating element 22. (See also...) Figure 8 , Figure 10 and Figure 11 The distance gradually increases along the directions indicated by arrows F1 and F2, that is, the distance d2 is greater than d1.

[0087] In some food processors, the connecting bracket 322 includes a first connecting portion and two second connecting portions. The first connecting portion is parallel to the heating plate, thus the distance between the first connecting portion and the heating plate support is equidistant everywhere. Typically, the length of the first connecting portion is at least half the diameter of the motor. Each of the opposite ends of the first connecting portion is connected to one of the second connecting portions; the second connecting portions are connected to the bottom connecting portion 323, for example, the second connecting portions are perpendicular to the heating plate. In this case, the motor front bracket 32 ​​also extends into the space 220 enclosed by the heating plate 21 and the heating element 22, and the motor 3 also satisfies the aforementioned relationship.

[0088] As described above, with the top connecting part 321 as a reference, the distance between the connecting bracket 322 and the heating plate 21 along the axial direction of the motor shaft 33 gradually increases along the direction from the motor shaft 33 to the heating element 22. Combined with the fact that the front bracket 32 ​​of the motor extends into the space 220 enclosed by the heating plate 21 and the heating element 22, compared to the distance between the first connecting part and the heating plate 21 being equal everywhere, this application ensures that the front bracket 32 ​​of the motor 3 is farther away from the heating plate 21 while reducing the distance between the motor 3 and the heating plate 21. This is beneficial to avoid excessive heat transfer from the heating plate 21 and the heating element 22 to the motor 3, and to avoid the motor 3 from overheating during operation.

[0089] Furthermore, in some embodiments, the connecting frame includes a first section and a second section. The first section is parallel to the motor shaft 33, and the second section is perpendicular to the motor shaft 33, forming an L-shape. Due to safety regulations, internal motor components need to be moved downwards (e.g., the enameled wire needs to be a certain distance from the second section), resulting in a larger motor height and consequently, a larger axial height of the food processor along the motor shaft. This gradual increase in height allows for the assembly of motor components (e.g., the enameled wire) within the connecting frame 332, eliminating the need for downward movement of internal components and providing greater electrical clearance. Therefore, a lower motor height also contributes to a lower axial height of the food processor along the motor shaft 33.

[0090] The following describes some features of the motor front bracket 32:

[0091] a) See Figure 14 The connecting frame 322 includes a support sidewall, which is shaped like a frustum or a truncated pyramid. See also... Figure 14The angle between the sidewall of the bracket and the plane perpendicular to the motor shaft 33 is α, where 110 degrees ≤ α ≤ 150 degrees. For example, 110 degrees, 112 degrees, 115 degrees, 118 degrees, 120 degrees, 123 degrees, 125 degrees, 128 degrees, 130 degrees, 133 degrees, 135 degrees, 138 degrees, 140 degrees, 143 degrees, 145 degrees, 148 degrees, 149 degrees, or 150 degrees. Of course, the gradual increase in size is not limited to the aforementioned frustum or truncated pyramid shape.

[0092] As described above, since 110 degrees ≤ a ≤ 150 degrees, the height of the connecting bracket 322 in the axial direction of the motor shaft 33 is relatively low. This design helps to prevent excessive heat from the heating plate assembly 2 from being transferred to the motor 3, and also helps to reduce the height of the food processor along the axial direction of the motor shaft 33.

[0093] b) See also Figure 7 , Figure 8 , Figure 10 and Figure 11 The heating element 22 includes a bottom portion opposite to the heating plate; the projection of the motor front bracket 32 ​​onto the heating plate 21 is located within the annular area enclosed by the projection of the bottom portion of the heating element onto the heating plate 21; or, the projections of the motor front bracket 32 ​​and the front end 311 of the outer casing onto the heating plate 21 are located within the annular area enclosed by the projection of the bottom portion of the heating element onto the heating plate 21. Thus, along a direction perpendicular to the motor shaft 33, the distance between the outer surface of the motor casing 31 and the heating element 22 is H, where H ≥ 0. In some embodiments, the radius of the motor 3 is R, where 0 ≤ H ≤ R / 2. The annular area enclosed by the projection of the bottom portion of the heating element onto the heating plate 21 can be formed as follows: the heating element 22 is annular such that the projection of the bottom portion of the heating plate onto the heating plate 21 encloses the annular area. The annular shape of the heating element 22 can be a C-shaped annular shape formed by an arc or a curved annular shape; in short, the annular shape formed by the heating element 22 is sufficient to heat the food. The ring shape can be a closed ring or an open ring.

[0094] As described above, since the projection of the motor front bracket 32 ​​onto the heating plate 21 is located within the annular area enclosed by the projection of the bottom of the heating element onto the heating plate 21, or the projections of the motor front bracket 32 ​​and the front end 311 of the outer casing onto the heating plate 21 are located within the annular area enclosed by the projection of the bottom of the heating element onto the heating plate 21, the motor 3 can avoid the heating element 22 and approach the heating plate 21. This helps to reduce the distance between the motor 3 and the heating plate 21, and consequently, helps to reduce the axial height of the food processor along the motor shaft 33. Of course, this feature, combined with the aforementioned gradual increase, not only helps to reduce the axial height of the food processor along the motor shaft 33, but also helps to prevent excessive heat transfer from the heating plate 21 and the heating element 22 to the motor 3.

[0095] Of course, for the motor front bracket 32 ​​to extend into the space 220, the projection of the motor front bracket 32 ​​may be located outside the annular area enclosed by the projection of the bottom of the heating element on the heating plate 21. In this case, the motor front bracket 32 ​​can avoid the heating element 22, and the minimum avoidance distance is Y, where Y≥2mm.

[0096] c) See also Figure 8 and Figure 10 The heating plate 21 includes a plate body 211 and a protrusion 212 protruding into the stirring cup 1. The plate body 211 surrounds the protrusion 212. The intersection of the connecting bracket 322 and the top connecting portion 321 is not lower than the plate body 211. Figure 3 The height difference is shown as p. The top connecting part 321 extends into the protrusion 212. The top connecting part 321 includes a top cavity that can accommodate an oil seal, etc. The protrusion 212 includes a connecting hole. The cutter assembly includes a cutter shaft. The cutter shaft and the motor shaft 33 are connected through the connecting hole. Figure 3 The diagram shows the motor shaft 33 passing through the connecting hole and connecting to the cutter shaft of the cutter assembly. Alternatively, the cutter shaft can pass through the connecting hole and connect to the motor shaft 33. The connection between the cutter shaft and the motor shaft 33 via the connecting hole includes the case where the cutter shaft and the motor shaft 33 are integrally constructed.

[0097] As described above, since the protrusion 212 protrudes towards the interior of the mixing cup 1, the intersection of the connecting bracket 322 and the top connecting portion 321 is not lower than the main body 211 of the plate; the top connecting portion 321 extends into the protrusion 212, which is more conducive to reducing the height of the food processor along the axial direction of the motor shaft 33. In addition, the extension of the top connecting portion 321 into the protrusion 212 can also help position the assembly of the motor 3, making the assembly of the motor convenient.

[0098] d) See Figure 8 , Figure 10 and Figure 11 The maximum distance between the connecting bracket 322 and the heating plate 21 along the axial direction of the motor shaft 33 is d (increasing from d1 to d2, and from d2 to d until the maximum distance is d), 5mm≤d≤25mm, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm or 25mm.

[0099] As described above, since 5mm≤d≤25mm, the space enclosed by the motor front bracket 32, the heating plate 21, and the heating element 22 is relatively large (for example, after assembling the motor 3 with the cup holder assembly, the space enclosed by the motor front bracket 32, the heating plate 21, and the heating element 22 has no mounting structure, making the space larger). This provides a larger heat dissipation space, which is more conducive to preventing excessive heat transfer from the heating plate assembly 2 to the motor 3, and helps to prevent the motor 3 from overheating during operation. In addition, with 5mm≤d≤25mm, it is also beneficial to reduce the axial height of the food processor along the motor shaft 33.

[0100] See Figure 14 The motor 3 is a DC motor. The axial height of the motor 3 along the motor shaft 33 is L, 30mm ≤ L ≤ 75mm, for example, 30mm, 32mm, 35mm, 38mm, 40mm, 43mm, 45mm, 48mm, 50mm, 53mm, 55mm, 57mm, 60mm, 62mm, 65mm, 68mm, 70mm, 72mm, or 75mm. The diameter of the motor 3 is w, w ≤ 76.5mm. The load torque of the motor is T, 105N·m ≤ T ≤ 135N·m. The no-load speed of the motor is V, 12000r / min ≤ V ≤ 14500r / min. The load speed of the motor is v: 9000r / min ≤ v ≤ 11000r / min. See also... Figure 10 Along the axial direction of the motor shaft 33 of the motor 3, the height of the cup holder assembly is k, where k≤85mm.

[0101] As described above, if the motor 3 or the cup holder assembly meets any of the above conditions, it is beneficial to ensure that the height of the motor 3 or the cup holder assembly is low. Consequently, the height of the mixing cup assembly 10 along the axial direction of the motor shaft 33 is low, which also ensures that the height of the mixing cup assembly 10 is low. When the mixing cup assembly 10 and the base 20 are detachably assembled, it also facilitates convenient handling of the mixing cup assembly by the consumer.

[0102] In various embodiments of this application, when the motor 3 includes a front motor bracket 32, a motor housing 31, and a rear motor bracket 34, they can be assembled as follows: The front motor bracket 32 ​​and the rear motor bracket 34 are each provided with mounting holes 320. Bolts pass through the mounting holes 320 and, in conjunction with locking elements (such as nuts or screws), fasten the front motor bracket 32 ​​and the rear motor bracket 34. After fastening, the motor housing 31 is clamped between the front motor bracket 32 ​​and the rear motor bracket 34. With the above arrangement, since the front motor bracket 32 ​​and the rear motor bracket 34 fasten the motor housing 31 between them, the assembly of the motor 3 is simple and convenient.

[0103] In some embodiments, the motor housing 31 is through-hole shaped and includes two opposing openings (a front opening and a rear opening), and both the front motor bracket 32 ​​and the rear motor bracket 34 are cover-shaped. The front motor bracket 32 ​​and the rear motor bracket 34 each cover one of the openings. The motor 3 includes a fan (not shown) connected to the motor shaft 33. At least one of the front motor bracket 32, the rear motor bracket 34, and the motor housing 31 is provided with a through hole 310, which connects the interior and exterior of the motor 3. Figure 5 The diagram shows that both the front bracket 32 ​​of the motor and the housing 31 of the motor are provided with the through hole 310.

[0104] As described above, by providing the through hole 310, which connects the interior and exterior of the motor 3, the fan rotation can dissipate heat from inside the motor 3 through the through hole 310 to the exterior, thus helping to prevent the motor 3 from overheating during operation. Simultaneously, carbon dust generated by the motor 3 can also be discharged to the exterior through the through hole 310. Furthermore, the front motor bracket 32 ​​and the rear motor bracket 34 are cover-shaped. On one hand, the front motor bracket 32 ​​and the rear motor bracket 34 are individually strong; on the other hand, the cover-shaped design of the front motor bracket 32 ​​and the rear motor bracket 34 also helps to prevent liquids such as water from entering the interior of the motor 3.

[0105] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
