Description

Technical Field

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

[0002] Patent CN116172423B discloses a food processor with an electromagnetic drive device installed within the main unit. The mixing component is housed within the mixing cup assembly and includes a driven magnet. The electromagnetic drive device enables both the rotation of the mixing element and the attachment of the mixing component to the bottom of the cup. By employing an electromagnetic drive device, the main unit eliminates the need for a motor, resulting in significant space savings and a reduced overall height.

[0003] In one embodiment of the patent, the iron core is cylindrical, and an electromagnetic coil is spirally wound around the iron core. Multiple iron cores are surrounded by annular winding supports to form a stator assembly. In a second embodiment of the patent, each iron core includes a first end located below the driven magnet and a second end located away from the first end. The second ends of all iron cores converge at the same point or are located on the same plane.

[0004] Because the electromagnetic drive device generates heat during operation, both the winding support surrounding the stator and the second end where the iron core is concentrated at a point will obstruct heat dissipation from the iron core. In particular, when the iron core is concentrated, the heat in the center of the iron core cannot dissipate outward. If the electromagnetic drive device operates for a long time, there will be a problem of stator overheating. Even if this solution relies on the large spacing between the columnar iron cores to reduce the heat dissipation requirement, the large spacing of the iron core structure itself limits the transmission of torque and cannot achieve high torque output.

[0005] Patent CN112421813B discloses a stator core, stator assembly, motor, food processor, and air supply device. The food processor requires a motor to drive the stirring blades. The motor includes a housing, a rotor assembly, and a stator assembly. A fan blade assembly is included, which rotates under the drive of the rotor assembly, driving gas flow. Although the stator core is a hollow cylindrical structure, the central through-hole is used to house the rotor assembly, allowing for easy insertion of the rotor assembly's rotating shaft. Furthermore, the rotor blocks the upper end of the central through-hole in the stator. Therefore, despite the fan blade assembly, it can only drive airflow along the outer periphery and surface of the stator for heat dissipation. The heat-generating area in the center of the stator is obstructed by the rotating shaft and rotor, preventing smooth airflow in the central region and resulting in inefficient heat dissipation in the central area. Utility Model Content

[0006] This invention provides a food processing machine based on magnetic drive, which solves the heat dissipation problem of the drive device, especially the technical problem that the heat in the central area of ​​the drive device cannot be dissipated efficiently, while achieving efficient magnetic drive.

[0007] The technical solution adopted in this utility model is as follows:

[0008] This utility model provides a food processing machine, including a mixing cup, a heating element for heating the mixing cup, and a stirring blade located inside the mixing cup. The stirring blade is fixedly connected to a transmission disk. The food processing machine also includes an electromagnetic drive device for driving the transmission disk. The electromagnetic drive device is fixedly connected to the bottom of the mixing cup. The electromagnetic drive device includes a ring-shaped stator body and multiple stator teeth with coils wound around the top of the stator body. The multiple stator teeth are arranged at intervals around the central hole of the stator body, forming a first channel communicating with the outside between adjacent stator teeth. The multiple stator teeth form a hollow hole communicating with the first channel and penetrating axially. The hollow hole communicates with the central hole to form a second channel. The food processing machine also includes a fan located below the mixing cup to drive airflow along the first and second channels.

[0009] The food processing machine provided by this utility model has an electromagnetic drive device fixed to the bottom of the mixing cup, bringing it close to the bottom wall of the cup. Regardless of whether the transmission disk is located inside or outside the mixing cup, this close proximity reduces the transmission distance and achieves efficient and accurate magnetic transmission. The electromagnetic drive device includes a ring-shaped stator body and multiple stator teeth with coils wound around them, protruding from the top of the stator body. This simple structure achieves electromagnetic drive, eliminating the need for a motor-driven disk in traditional technology, thus simplifying the main unit structure and facilitating miniaturization. Furthermore, the stator teeth protrude from the top of the stator body, rather than from its inner circumference. Based on this, multiple stator teeth are arranged at intervals around the central hole of the stator body, forming a first channel between adjacent teeth. These multiple teeth then form multiple first channels, which together enclose a hollow hole that communicates with the first channels and extends axially. This hollow hole communicates with the central hole to form a second channel. When the fan is operating, taking the first channel intake as an example, the cold airflow around the stator is driven radially through multiple first channels directly into the hollow holes of the stator, i.e., the central region of the stator. The cold airflow exchanges heat with the central region of the stator, generating hot airflow. Driven by the fan, the hot airflow is discharged along the second channel, which connects the hollow holes and the central hole, thus carrying away heat from the coils, especially from the central region of the stator, achieving efficient and thorough heat dissipation. The connection between the first and second channels forms a circulating airflow channel that connects to the outside, allowing airflow to circulate into the central region of the stator, achieving heat dissipation for the stator body, stator teeth, and coils. Simultaneously, as the airflow flows along the first and second channels, it also exchanges heat with the bottom wall of the stirring cup, carrying away heat from the stator body, coils, and the bottom wall of the stirring cup, resulting in more efficient and thorough heat dissipation. Of course, if the fan reverses the flow direction, with airflow entering through the second channel and exiting through the first channel, the same effect can be achieved.

[0010] In a preferred embodiment, the transmission disk is located inside the mixing cup and supported by the bottom wall of the mixing cup, and the stator teeth abut against the bottom wall of the mixing cup.

[0011] When the drive disk is located inside the mixing cup, there is no need to make a hole in the bottom wall of the cup to connect the drive disk and the mixing cup, thereby improving the waterproof effect of the mixing cup and making it easy to fix the drive disk and the mixing blade into one piece to form a detachable blade assembly, which is convenient for users to clean and use flexibly. When the drive disk is located inside the mixing cup, sufficient space can be reserved below the bottom wall of the cup, allowing the stator teeth to abut against the bottom wall of the mixing cup. This prevents the formation of gaps between the stator teeth and the bottom wall, thus avoiding disordered airflow. When airflow passes through the first and second channels, it allows for orderly flow along the channels and direct contact with the top wall of the cup, efficiently removing heat and improving heat dissipation. Furthermore, since magnetic eddy currents exist between the drive disk and the electromagnetic drive, causing localized high temperatures at the corresponding bottom wall location, abutting the stator teeth against the bottom wall effectively solves the problem of localized high temperatures and uneven heating caused by magnetic eddy currents, preventing scorching.

[0012] In a preferred embodiment, the stirring cup includes a cup body and a cup base fitted to the bottom of the cup body, with a heat dissipation cavity formed between the cup base and the cup body, and the electromagnetic drive device and the fan are both fixed in the heat dissipation cavity.

[0013] By employing a mixing cup with a cup body and a cup base, the structure of the mixing cup is simplified. The cup base provides support for the mixing cup, allowing users to place it flexibly. A heat dissipation cavity is formed between the cup base and the cup body, concentrating airflow. Both the electromagnetic drive device and the fan are fixed within this heat dissipation cavity, facilitating assembly. Furthermore, the fan dissipates heat directly from the electromagnetic drive device, achieving highly efficient heat dissipation.

[0014] In a preferred embodiment, the bottom wall of the cup holder is provided with a first fixing part for fixing the fan and a second fixing part that extends upward relative to the first fixing part to fix the stator body.

[0015] By setting a first fixing part and a second fixing part on the bottom wall of the cup holder, no additional installation structure is required. The fan and stator body can be fixed to the first fixing part and the second fixing part to achieve modular assembly of the three. Then, the cup holder and the cup body are assembled to complete the overall assembly of the mixing cup. The assembly is simple, the structure is simple, and the whole machine is miniaturized.

[0016] In a preferred embodiment, the stirring cup further includes a mounting bracket located within the heat dissipation cavity, the mounting bracket being fixedly connected to the cup body, and both the electromagnetic drive device and the fan being fixed to the mounting bracket.

[0017] By setting up a mounting bracket, the cup holder can be processed independently, the fixing strength of the electromagnetic drive device and the fan can be strengthened, and the cup holder can be prevented from deforming. The mounting bracket integrates the electromagnetic drive device and the fan, which allows the fan to be close to the stator body, reducing airflow loss and improving heat dissipation efficiency.

[0018] In a preferred embodiment, the stirring cup includes a cup body and a mounting bracket fixed to the bottom of the cup body. The mounting bracket is interference-fitted onto the outer periphery of the stator body. The bottom wall of the cup body is provided with a downwardly extending mounting post, which is fixedly connected to the mounting bracket.

[0019] The mounting bracket is interference-fitted onto the outer periphery of the stator body, eliminating the need for additional parts to fix the stator body to the mounting bracket. At the same time, the mounting bracket does not obstruct the flow path of heat dissipation airflow, which is beneficial for efficient heat dissipation.

[0020] In a preferred embodiment, the stirring cup includes a cup body and a mounting bracket fixed to the bottom of the cup body. The mounting bracket includes an annular frame supported on the bottom of the stator body and a mounting lug protruding from the outer periphery of the annular frame. The bottom of the cup body is provided with a downwardly extending mounting post, and the mounting lug is fixedly connected to the mounting post.

[0021] By fixing the device to the downward-extending mounting posts and brackets, whether via mounting lugs or direct fixation to the mounting brackets fitted around the stator body, the electromagnetic drive unit can be hoisted. This reduces the installation tolerance between the stator teeth and the bottom wall of the housing, allowing the stator teeth to be closer to the bottom wall and reducing the axial distance between the stator teeth and the transmission disk, thus achieving reliable and efficient transmission. Simultaneously, the combination of the ring frame and mounting lugs does not obstruct the airflow path for heat dissipation, ensuring efficient heat dissipation in the central area of ​​the electromagnetic drive unit.

[0022] In a preferred embodiment, the food processor further includes a main unit, which has a mounting cavity for accommodating the mixing cup and the electromagnetic drive device. The mixing cup is detachably or fixedly installed in the mounting cavity, and the fan is fixedly installed on the main unit and located below the electromagnetic drive device.

[0023] The food processing machine includes a main unit, which forms an installation cavity to house the mixing cup and electromagnetic drive device. This cavity provides reliable positioning and reduces noise transmission during the operation of the mixing cup, thus achieving a noise reduction effect. Additionally, the fan is fixedly installed on the main unit, which also reduces the weight of the mixing cup. With the mixing cup detachably installed on the main unit, it is convenient for users to easily handle the mixing cup.

[0024] In a preferred embodiment, the stirring cup includes a cup body with an open bottom and a heating plate assembly encapsulated at the bottom of the cup body, the heating element is fixed to the heating plate assembly, and the top of the stator tooth is welded to the heating plate assembly.

[0025] By setting up a heating plate assembly, cups and heating plate assemblies made of different materials can be used, such as glass cups and metal heating plate assemblies, to accelerate the heat transfer efficiency of the heating element. The top of the stator teeth can be welded and fixed to the heating plate assembly, which is a direct and simple fixing method. This allows the heat dissipation airflow in the first and second channels to directly exchange heat with the heating plate assembly, effectively dissipating heat from the heating plate assembly, preventing local high temperatures caused by magnetic eddy currents, and avoiding scorching.

[0026] In a preferred embodiment, the fan is coaxially positioned below the stator body and draws the airflow of the second channel downwards.

[0027] By coaxially positioning the fan below the stator body, specifically below the second channel, and drawing the airflow downwards from the second channel, the airflow entering the second channel from the first channel can be more effectively extracted. This prevents the hot airflow that has already undergone heat exchange from remaining in the first and second channels for too long, thus accelerating airflow and improving heat dissipation efficiency. Simultaneously, by drawing the airflow downwards from the second channel, the cool airflow enters radially along multiple first channels, while the hot airflow, after heat exchange, is concentrated and discharged axially along the second channel. This enhances the airflow for heat dissipation and prevents the hot airflow from escaping and diffusing back into the first channel, thus avoiding impact on heat dissipation and preventing the hot airflow from affecting other components within the heat dissipation cavity below the bottom wall of the cup.

[0041] like Figure 1-5 As shown, in one embodiment of the present invention, a food processing machine is provided, including a mixing cup 10, a heating element for heating the mixing cup 10, and a stirring blade 20 located inside the mixing cup 10. The stirring blade 20 is fixedly connected to a transmission disk 21. The food processing machine also includes an electromagnetic drive device 30 for driving the transmission disk 21. The electromagnetic drive device 30 is fixedly connected to the bottom of the mixing cup 10. The electromagnetic drive device 30 includes an annular stator body 31 and a plurality of stator teeth 32 with coils wound around the top of the stator body 31. The plurality of stator teeth 32 are arranged at intervals around the central hole of the stator body 31, forming a first channel 33 communicating with the outside between adjacent stator teeth 32. The plurality of stator teeth 32 form a hollow hole communicating with the first channel 33 and penetrating axially. The hollow hole communicates with the central hole to form a second channel 34. The food processing machine also includes a fan 40 located below the mixing cup 10 to drive airflow along the first channel 33 and the second channel 34.

[0042] The food processing machine provided by this utility model has an electromagnetic drive device 30 fixed to the bottom of the mixing cup 10, bringing it closer to the bottom wall of the mixing cup 10. Whether the transmission disk 21 is located inside or outside the mixing cup 10, the distance between the electromagnetic drive device 30 and the transmission disk 21 is reduced, thereby decreasing the transmission distance and achieving efficient and accurate magnetic transmission. The electromagnetic drive device 30 includes a ring-shaped stator body 31 and multiple stator teeth 32 with coils wound around them, protruding from the top of the stator body 31. It utilizes a simple structure to achieve electromagnetic drive, eliminating the need for a motor-driven disk in traditional technology to achieve magnetic drive, thus simplifying the main unit structure and facilitating miniaturization of the main unit. Furthermore, the stator teeth 32 protrude from the top of the stator body 31, rather than from the inner circumferential surface of the stator body 31. Based on this, multiple stator teeth 32 are arranged at intervals around the central hole of the stator body 31, forming a first channel 33 between adjacent stator teeth 32. Thus, multiple stator teeth 32 form multiple first channels 33, which together enclose a hollow hole that communicates with the first channels 33 and extends axially. The hollow hole communicates with the central hole to form a second channel 34. When the fan 40 is working, taking the intake of air through the first channel 33 as an example, it drives the cold airflow around the stator to enter the hollow hole of the stator directly from the multiple first channels 33 along the stator radial direction, i.e., the central region of the stator. The cold airflow exchanges heat with the central region of the stator to generate hot airflow. Under the power of the fan 40, the hot airflow is discharged along the second channel 34 formed by the connection between the hollow hole and the central hole, thereby carrying away the heat of the coil, especially the heat of the central region of the stator, achieving efficient and sufficient heat dissipation. The connection between the first channel 33 and the second channel 34 forms a circulating air duct that connects to the outside environment. This allows airflow to circulate into the central area of ​​the stator, achieving heat dissipation for the stator body 31, stator teeth 32, and coils. Simultaneously, as the airflow flows along the first channel 33 and the second channel 34, it also exchanges heat with the bottom wall of the stirring cup 10, thus carrying away heat from the stator body 31, coils, and the bottom wall of the stirring cup 10. This results in more efficient and thorough heat dissipation, improving overall cooling efficiency. Of course, if the fan 40 reverses the flow direction, directing airflow from the second channel 34 into the first channel 33 and out through the first channel 33, the same effect can be achieved.

[0043] This utility model is a preferred embodiment, such as... Figure 3 , 4 As shown, the arrow indicates the airflow direction. The fan 40 is coaxially positioned below the stator body 31, and the airflow from the second channel 34 is drawn downwards. More preferably, a heat dissipation cavity 101 for accommodating the electromagnetic drive device 30 is provided at the bottom of the stirring cup 10. The heat dissipation cavity 101 has a heat dissipation port, and an air guide shroud 41 is provided on the outside of the fan 40. The air guide shroud 41 connects the second channel 34 with the heat dissipation port.

[0044] By coaxially arranging the fan 40 below the stator body 31, i.e., below the second channel 34, and drawing the airflow downwards from the second channel 34, the airflow entering the second channel 34 from the first channel 33 can be more fully extracted. This prevents the hot airflow that has already undergone heat exchange from staying in the second channel 34 and the first channel 33 for too long, thus accelerating the airflow speed and improving heat dissipation efficiency. Simultaneously, by drawing the airflow downwards from the second channel 34 by the fan 40, the cool airflow enters radially along multiple first channels 33, and the hot airflow, after heat exchange, is concentrated and discharged axially along the second channel 34. This enhances the airflow for heat dissipation and prevents the hot airflow from escaping and diffusing back into the first channel 33, thus avoiding impact on the heat dissipation effect and preventing the hot airflow from affecting other components within the heat dissipation cavity 101 below the bottom wall of the cup.

[0045] This invention does not limit the form of the food processing machine, which can be selected as either Embodiment 1 or Embodiment 2 below.

[0046] Implementation method one, such as Figure 1-4 As shown, the food processing machine is a soymilk maker. Specifically, the mixing cup 10 includes a cup body 11 and a cup holder 12 fitted onto the bottom of the cup body. A heat dissipation cavity 101 is formed between the cup holder 12 and the cup body 11. The electromagnetic drive device 30 and the fan 40 are both fixed in the heat dissipation cavity 101. Preferably, the cup holder extends to completely enclose the cup body. Of course, the cup holder can be fixed to the bottom of the cup body, leaving the cup body exposed.

[0047] By employing a mixing cup 10 with a cup body and a cup base, the structure of the mixing cup 10 is simplified. The mixing cup 10 can be supported by the cup base, allowing users to place the mixing cup 10 flexibly. A heat dissipation cavity 101 is formed between the cup base and the cup body, which concentrates airflow. The electromagnetic drive device 30 and the fan 40 are both fixed in the heat dissipation cavity 101, facilitating assembly. The fan 40 dissipates heat directly from the electromagnetic drive device 30, achieving efficient heat dissipation.

[0048] like Figure 2 As shown, in a preferred embodiment of this invention, the drive disk 21 is located inside the stirring cup 10 and supported by the bottom wall of the stirring cup 10, and the stator tooth pole 32 abuts against the bottom wall of the stirring cup 10. More specifically, a blade holder 22 is also provided on the outside of the drive disk 21, which is supported on the bottom wall of the cup. The drive disk 21 and the stirring blade 20 are fixedly connected by a drive shaft 23.

[0049] When the drive disk 21 is located inside the mixing cup 10, it eliminates the need to make a hole in the bottom wall of the cup to connect the drive disk 21 and the mixing cup 10, thereby improving the waterproof effect of the mixing cup 10 and making it easy to fix the drive disk 21 and the mixing blade 20 into one piece to form a detachable blade assembly, which is convenient for users to clean and use flexibly. When the drive disk 21 is located inside the mixing cup 10, sufficient space can be reserved below the bottom wall of the cup, so that the stator teeth 32 can abut against the bottom wall of the mixing cup 10. When the airflow flows through the first channel 33 and the second channel 34, it avoids the formation of gaps between the stator teeth 32 and the bottom wall of the cup, which would cause disordered airflow for heat dissipation. Therefore, when airflow passes through the first channel 33 between adjacent stator teeth 32, the airflow in different first channels 33 can flow orderly along the first channel 33 and then directly contact the top wall of the bottom wall of the cup, effectively removing the heat from the top wall of the bottom wall of the cup, thus forming a better heat dissipation effect on the bottom wall of the mixing cup 10. In addition, since there are magnetic eddy currents between the drive disk 21 and the electromagnetic drive, local high temperatures occur at the corresponding bottom wall position. Therefore, abutting the stator teeth 32 against the bottom wall of the mixing cup 10 effectively solves the problem of local high temperature and uneven heat caused by magnetic eddy currents, and avoids scorching.

[0050] Of course, the configuration of the transmission disk 21 in this utility model is not limited to the one described above. As another preferred embodiment of this invention, the transmission disk 21 is located below the cup body, and the stirring blade 20 is connected to the transmission disk 21 by a transmission shaft 23, which passes through the bottom wall of the stirring cup 10.

[0051] It is understood that the configuration of the aforementioned transmission disk 21 in this utility model may be combined with other embodiments and examples of this utility model.

[0052] In this embodiment, the fixing method of the electromagnetic drive device 30 and the fan 40 can be selected as follows:

[0053] Implementation Example 1, such as Figure 1-4 As shown, the stirring cup 10 also includes a mounting bracket 50 located in the heat dissipation cavity 101. The mounting bracket 50 is fixedly connected to the cup body, and the electromagnetic drive device 30 and the fan 40 are both fixed to the mounting bracket 50.

[0054] By setting the mounting bracket 50, the independent processing of the cup holder can be facilitated, the fixing strength of the electromagnetic drive device 30 and the fan 40 can be strengthened, and the cup holder can be prevented from deforming. The mounting bracket 50 integrates the electromagnetic drive device 30 and the fan 40, which facilitates the fan 40 to be close to the stator body 31, reduces airflow loss, and improves heat dissipation efficiency.

[0055] like Figure 3 , 4As shown, the mounting bracket 50 includes an annular frame supported on the bottom of the stator body 31 and a mounting lug 51 protruding from the outer periphery of the annular frame. The bottom of the cup body is provided with a downwardly extending mounting post, and the mounting lug 51 is fixedly connected to the mounting post.

[0056] Alternatively, the mounting bracket 50 can be interference-fitted onto the outer periphery of the stator body 31, and the bottom wall of the cup body is provided with a downwardly extending mounting post, which is fixedly connected to the mounting bracket 50.

[0057] By interlocking the mounting bracket 50 onto the outer periphery of the stator body 31, no additional parts are needed to fix the stator body 31 to the mounting bracket 50. Simultaneously, the mounting bracket 50 does not obstruct the airflow path for heat dissipation, facilitating efficient heat dissipation. The electromagnetic drive device 30 can be hoisted by fixing it to the downward-extending mounting post and mounting bracket 50, whether via the mounting lug 51 or directly to the mounting bracket 50 fitted onto the outer periphery of the stator body 31. This reduces the installation tolerance between the stator teeth 32 and the bottom wall of the cup, allowing the stator teeth 32 to be closer to the bottom wall of the cup, thus reducing the axial distance between the stator teeth 32 and the transmission disk 21, achieving reliable and efficient transmission. Furthermore, the combination of the ring frame and the mounting lug 51 still does not obstruct the airflow path for heat dissipation, achieving efficient heat dissipation in the central area of ​​the electromagnetic drive device 30.

[0058] In Example 2, the bottom wall of the cup holder is provided with a first fixing part for fixing the fan 40 and a second fixing part extending upward relative to the first fixing part to fix the stator body 31. For example, the first fixing part is the bottom wall of the cup holder, and the second fixing part is a support column or ring rib protruding from the bottom wall of the cup holder.

[0059] By setting a first fixing part and a second fixing part on the bottom wall of the cup holder, no additional installation structure is required. The fan 40 and the stator body 31 can be fixed to the first fixing part and the second fixing part to achieve modular assembly of the three. Then, the cup holder and the cup body are assembled to complete the overall assembly of the stirring cup 10. The assembly is simple, the structure is simple, and the whole machine is miniaturized.

[0060] It is understandable that the electromagnetic drive device can be installed using the above implementation example, regardless of whether the drive disk is located inside or outside the mixing cup.

[0061] Example 3: The stirring cup 10 includes a cup body with an open bottom and a heating plate assembly encapsulated at the bottom of the cup body. The heating element is fixed to the heating plate assembly, and the top of the stator tooth 32 is welded to the heating plate assembly.

[0062] By setting up a heating plate assembly, cups and heating plate assemblies made of different materials can be used, such as glass cups and metal heating plate assemblies, to accelerate the heat transfer efficiency of the heating element. The top of the stator tooth pole 32 is welded and fixed to the heating plate assembly. The fixing method is direct and simple, and the heat dissipation airflow in the first channel 33 and the second channel 34 can directly exchange heat with the heating plate assembly, which can effectively dissipate heat from the heating plate assembly, prevent local high temperature caused by magnetic eddy currents, and avoid burning the bottom.

[0063] Implementation method two, such as Figure 5 As shown, the food processor provided in this embodiment is a food processor that does not require hand washing. It includes a main unit 13. The main unit 13 is provided with a mounting cavity 14 for accommodating a mixing cup 10 and an electromagnetic drive device 30. The mixing cup 10 can be detachably installed or fixedly installed in the mounting cavity. The fan 40 is fixedly installed on the main unit and located below the electromagnetic drive device 30.

[0064] In this embodiment, the food processing machine includes a main unit, which forms an installation cavity so that the mixing cup 10 and the electromagnetic drive device 30 can be accommodated in the installation cavity. The positioning is reliable, and the noise transmitted to the outside during the operation of the mixing cup 10 is reduced, which has a noise reduction effect. At the same time, the fan 40 is fixedly installed on the main unit, which also reduces the weight of the mixing cup 10. When the mixing cup 10 is detachably installed on the main unit, it is convenient for the user to easily pick up the mixing cup 10.

[0065] In this embodiment, the fixing of the electromagnetic drive device 30 can still refer to Embodiment Example 1. For example, the stirring cup 10 includes a cup body and a mounting bracket 50 fixed to the bottom of the cup body. The mounting bracket 50 is interference-fitted to the outer periphery of the stator body 31. The bottom wall of the cup body is provided with a downwardly extending mounting post, which is fixedly connected to the mounting bracket 50.

[0066] It is understandable that when the mixing cup 10 is detachable from the main unit, the mounting bracket 50 can form the cup holder as described in Embodiment 1, or the mounting bracket 50 can be set independently of the cup holder. When the mixing cup 10 is fixed to the main unit, the mounting bracket 50 can also be used to fix the fan 40. Regardless of whether the mixing cup 10 is detachable from the main unit or fixed, it can be fixed by welding the stator teeth 32 to the heating plate assembly.

[0067] Of course, the mounting bracket 50 may also include an annular frame supported on the bottom of the stator body 31 and a mounting lug 51 protruding on the outer periphery of the annular frame. The bottom of the cup body is provided with a downwardly extending mounting post, and the mounting lug 51 is fixedly connected to the mounting post.

[0068] By interlocking the mounting bracket 50 onto the outer periphery of the stator body 31, no additional parts are needed to fix the stator body 31 to the mounting bracket 50. Simultaneously, the mounting bracket 50 does not obstruct the airflow path for heat dissipation, facilitating efficient heat dissipation. The electromagnetic drive device 30 can be hoisted by fixing it to the downward-extending mounting post and mounting bracket 50, whether via the mounting lug 51 or directly to the mounting bracket 50 fitted onto the outer periphery of the stator body 31. This reduces the installation tolerance between the stator teeth 32 and the bottom wall of the cup, allowing the stator teeth 32 to be closer to the bottom wall of the cup, thus reducing the axial distance between the stator teeth 32 and the transmission disk 21, achieving reliable and efficient transmission. Furthermore, the combination of the ring frame and the mounting lug 51 still does not obstruct the airflow path for heat dissipation, achieving efficient heat dissipation in the central area of ​​the electromagnetic drive device 30.

[0069] In addition, the configuration of the transmission disk 21 in this embodiment can refer to Embodiment 1. Optionally, the transmission disk 21 is located inside the mixing cup 10; or, the transmission disk 21 is located outside the mixing cup 10 and is connected to the mixing blade 20 through the transmission shaft 23 that penetrates the bottom wall of the cup.

[0072] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
