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] The applicant's earlier Chinese invention patent CN201120194553.7 discloses an indirect transmission food processing machine, including an active coupling mounted on the motor's power output shaft and a driven coupling connected to the grinding blades. The driven coupling has a certain floating space in the axial direction, allowing the grinding blades to slide appropriately in the axial direction to disengage from jammed materials and ensure normal operation. This design allows the cup body to be designed as a completely sealed structure with no mechanical connection holes at the bottom, better solving the leakage problem of the mixing cup. Simultaneously, the grinding blades can be detached from the container for easy cleaning. In this design, a mechanical limiting device is provided inside the container to restrict the floating of the driven coupling.

[0003] To prevent the pulverizing blades from detaching from the mixing cup, existing technologies also disclose a magnetic fixing solution. For example, patent CN202321907134.2 discloses a blade assembly. The blade assembly has a positioning element at the center of the disc body, and the magnetically driven blade assembly is sleeved on the positioning element. The magnetically driven blade assembly and the positioning element are provided with a magnetically attracted element and a attracted element that attract each other, which is used to solve the problem of the magnetically driven blade assembly flying out and falling out of the mixing cup and causing injury.

[0004] Whether it's a mechanical limiting device or a magnetic fixing structure, the purpose of both is to strengthen the installation strength between the cutter and the cup body, preventing the cutter from detaching from the cup body during normal operation. For mechanical limiting devices, friction can be increased between the cutter and the cup body, or a matching latch can be used. However, such solutions require the user to first release the limiting device before operating the cutter, making operation cumbersome. Furthermore, the complex limiting structure located inside the container also makes cleaning inconvenient. Similarly, magnetic solutions require sufficiently strong magnetic force between the magnetic component and the attracted component to prevent the cutter from detaching from the positioning component. However, the user still needs to overcome the magnetic force to remove the cutter, resulting in strenuous operation and inconvenience.

[0005] The applicant aims to develop a locking device that can reliably limit the movement of the detachable blade assembly while preventing the generation of reaction force that would make disassembly difficult when the user needs to remove the blade assembly. Further research has been conducted on how to easily and reliably assemble the locking device into the cup body. Utility Model Content

[0006] This utility model provides a food processing machine based on a magnetically driven detachable blade assembly structure. Under the premise of ensuring reliable positioning between the blade assembly and the cup body, it solves the technical problem of laborious and cumbersome disassembly caused by the reaction force due to the positioning during the blade assembly disassembly process, and further realizes simple assembly.

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

[0008] This utility model provides a food processing machine, including a main unit, a mixing cup mounted on the main unit, and a blade assembly detachably mounted inside the mixing cup. The main unit is equipped with an electromagnetic drive device. The blade assembly includes a transmission disk driven by the electromagnetic drive device and a mixing blade connected to the transmission disk. The mixing cup includes a cup body and a cup base fixedly sleeved with the cup body. The blade assembly also includes an internal magnetic component. The mixing cup also includes a suction component that attracts the internal magnetic component and a control lever that pushes the suction component away from the internal magnetic component. The control lever is mounted on the cup base and extends from the cup base. The suction component is mounted on the cup base and is mounted below the cup body along with the cup base. After the cup base is sleeved and fixed with the cup body, the suction component adheres to the bottom wall of the cup body.

[0009] The food processing machine provided by this utility model features a detachable blade assembly installed inside the mixing cup for easy cleaning. It utilizes a suction component to engage with an internal magnetic element, ensuring the blade assembly is reliably installed within the mixing cup. Furthermore, after the cup base is fitted and fixed to the cup body, the suction component adheres to the bottom wall of the cup body. The suction component magnetically attracts the internal magnetic element within the mixing cup with sufficient magnetic force to prevent the blade assembly from detaching from the cup body during non-user operation. It reliably locks the blade assembly within the mixing cup, preventing it from flying out or falling off during user operation, thus achieving reliable positioning between the blade assembly and the cup body.

[0010] By setting a control lever, before the user needs to disassemble the blade assembly, pushing the lever moves the attraction component away from the inner magnetic component, increasing the distance between the magnetic poles of the attraction component and the inner magnetic component. According to Coulomb's law, the magnetic attraction between two magnets is inversely proportional to the square of the distance between them. Therefore, as the distance between the attraction component and the inner magnetic component increases, the magnetic attraction between them weakens rapidly, eventually reaching a state where the magnetic attraction between the outer and inner magnetic components is imperceptible to the user. This reduces the resistance encountered during the removal of the blade assembly, allowing the user to easily remove the pulverizing device from the cup assembly, making the removal of the blade assembly easier and more convenient.

[0011] By mounting the suction component onto the cup holder and then onto the bottom of the cup body, compared to directly mounting the suction component onto the cup body, the assembler is no longer required to invert the cup body for assembly, and the installation difficulty of the heating plate at the bottom of the cup body is eliminated. This simplifies the assembly of the suction component and reduces the number of fixing parts in the mixing cup. The assembly of the suction component and the cup body is achieved through the assembly of the cup holder and the cup body. Furthermore, the control lever is mounted on the cup holder, making the assembly of the suction component and control lever with the cup body more convenient. Moreover, the cup holder itself is fitted and fixed to the cup body, providing installation space. By uniformly placing the suction component and control lever on the cup holder, the fit tolerance between the two is reduced, resulting in high precision in the fit between the control lever and the suction component, smoother movement of the control lever without jamming, and less effort required for operation.

[0012] In a preferred embodiment, the inner side of the bottom wall of the cup holder is provided with a guide groove, and the suction assembly includes a positioning block. The positioning block is axially limited in the guide groove by a fixing member and slides along the extension direction of the guide groove.

[0013] By setting a guide groove and a positioning block, the positioning block slides along the guide groove to switch the suction assembly between an engaging position and a disengaged position with the inner magnetic component. This allows the user to unlock the knife assembly by driving the suction assembly away from the inner magnetic component using a joystick when the user needs to remove it. Simultaneously, the positioning block is axially limited in the guide groove by a fixing member, ensuring that the suction assembly and the cup holder are both positioned and slidably limited by the guide groove of the cup holder. This design is simple, allows for smooth sliding, and makes operating the push rod and disassembling the knife assembly effortless.

[0014] In a preferred embodiment, the fastener includes a screw, the positioning block is provided with a through hole, the screw passes through the through hole and is locked into the guide groove, and the through hole extends in a strip shape along the sliding direction of the positioning block;

[0015] A through hole is provided in the positioning block, through which a screw passes and locks into the guide groove, achieving axial positioning of the positioning block and the guide groove. Simultaneously, the through hole extends in a strip shape along the sliding direction of the positioning block, allowing the positioning block to slide relative to the screw and subsequently along the guide groove. The structure is simple.

[0016] In a preferred embodiment, the fastener includes a baffle plate fixed to the groove end of the guide groove.

[0017] The fixing component uses a baffle to axially stop the positioning block in the guide groove, preventing the positioning block from coming out of the guide groove, while allowing it to slide smoothly along the guide groove when the push rod pushes against it.

[0018] In a preferred embodiment, a guide groove is provided on the inner side of the bottom wall of the cup holder, the guide groove extends radially along the cup holder, and the suction assembly moves along the guide groove between positions close to and far from the center of the cup holder.

[0019] Since the diameter of the blade assembly is much smaller than that of the cup body, there is a large proportion of installation space between the blade assembly and the outer wall of the cup body. Correspondingly, this installation space is used to accommodate the suction assembly and form the movement space of the suction assembly. There is no need to add an additional installation space structure for the stirring cup, and the outer diameter and volume of the stirring cup will not be increased. It does not affect the structure and shape of the existing product.

[0020] In a preferred embodiment, the control lever is radially inserted into the cup holder and moves radially along the cup holder. The control lever is provided with a pushing surface, and the suction assembly is provided with a sliding surface that cooperates with the pushing surface. The pushing surface and the moving direction of the control lever form an angle.

[0021] The control lever is radially inserted into the cup holder and moves radially along the cup holder. It can extend laterally from the cup holder and be exposed to the user's view, making operation more intuitive and convenient. When the control lever is pushed, its pushing surface engages with the sliding surface of the magnetic assembly, smoothly moving the magnetic assembly away from the internal magnetic component for easy removal of the knife assembly.

[0022] In a preferred embodiment, the control lever is axially inserted into the cup holder and moves along the cup holder's axial direction. The control lever has a driving ramp, and the engaging assembly has a passive ramp that engages with the driving ramp. The driving ramp extends obliquely along the movement direction of the control lever. More preferably, the main unit has a clearance opening that avoids the control lever.

[0023] By inserting the control lever axially along the cup holder and moving it axially, the control lever can be automatically moved axially by the weight of the cup itself and the support of the surface when the mixing cup is placed on any table surface. This eliminates the need for manual operation by the user, automating the engagement assembly and making the removal and removal of the blade assembly easier. When the control lever contacts the table surface, the driving inclined surface of the control lever engages with the passive inclined surface of the engagement assembly, smoothly moving the magnetic assembly away from the internal magnetic component for easy removal of the blade assembly.

[0024] Preferably, the main unit has a clearance opening to avoid interfering with the control lever. This prevents the control lever from shifting and causing the blade assembly to unlock when the mixing cup is installed on the main unit. Therefore, even when the mixing cup is installed on the main unit, the reliable magnetic attraction between the attraction component and the internal magnetic element is still guaranteed, resulting in more stable operation of the stirring blade.

[0025] In a preferred embodiment, the attraction assembly includes an outer magnetic component that attracts the inner magnetic component and a mounting bracket with a mounting groove. The opening of the mounting groove faces the cup body. The outer magnetic component is fixed to the mounting groove and fits against the bottom wall of the cup body. The control lever pushes the mounting bracket to move.

[0026] The attraction assembly includes an outer magnetic component and a mounting bracket. The mounting bracket protects the outer magnetic component. Furthermore, the control lever pushes the mounting bracket to move, thereby moving the outer magnetic component. After prolonged movement and engagement, direct wear on the outer magnetic component is avoided, thus ensuring reliable magnetic attraction of the outer magnetic component. This allows the outer magnetic component and the inner magnetic component to reliably engage, providing a stable limiting effect for the blade assembly.

[0027] Preferably, the inner magnetic component and the outer magnetic component are arranged opposite each other along the axial direction of the cup holder, so that the space inside the cup holder is utilized more fully and the structure of the outer magnetic component and the electromagnetic drive device is compact.

[0028] In a preferred embodiment, the bottom of the cup holder has a transmission cavity into which the top end of the electromagnetic drive device extends, and the attraction assembly is disposed on the outer periphery of the transmission cavity. More preferably, the attraction assembly includes an outer magnetic element surrounding the outer periphery of the electromagnetic drive device, and an inner magnetic element located on the outer periphery of the transmission disk.

[0029] By providing a transmission cavity at the bottom of the cup holder for the top of the electromagnetic drive device to extend into, when the stirring cup is placed on the main unit, the electromagnetic drive device can fit closer to the bottom of the cup body, thereby having a closer distance with the transmission disk and ensuring stronger magnetic attraction and driving force.

[0030] By surrounding the electromagnetic drive device with an outer magnetic component that also fits against the bottom wall of the cup, installation interference between the outer magnetic component and the electromagnetic drive device is prevented. Therefore, while ensuring the magnetic attraction force between the electromagnetic drive device and the transmission disk, the magnetic attraction force between the outer magnetic component and the inner magnetic component can also be guaranteed.

[0046] like Figure 1-3 As shown, in one embodiment of the present invention, a food processing machine is provided, including a main unit 20, a mixing cup 10 mounted on the main unit 20, and a blade assembly 30 detachably mounted in the mixing cup 10. The main unit 20 is provided with an electromagnetic drive device. The blade assembly 30 includes a transmission disk 31 driven by the electromagnetic drive device and a mixing blade 32 connected to the transmission disk 31. Preferably, it also includes a blade holder 34 fitted around the outer periphery of the transmission disk 31 to protect the transmission disk. The mixing cup 10 includes a cup body 11 and a cup holder 12 fixedly sleeved with the cup body 11. The blade assembly 30 also includes an inner magnetic element 33. The mixing cup 10 also includes an attraction component 40 that attracts the inner magnetic element 33 and an operating lever 50 that pushes the attraction component 40 away from the inner magnetic element 33. The operating lever 50 is installed on the cup holder 12 and extends out of the cup holder 12. The attraction component 40 is installed on the cup holder 12 and installed below the cup body 11 along with the cup holder 12. After the cup holder 12 is sleeved and fixed with the cup body 11, the attraction component 40 adheres to the bottom wall of the cup body 11.

[0047] The food processor provided by this utility model features a detachable blade assembly 30 installed inside the mixing cup 10 for easy cleaning. Simultaneously, the blade assembly 30 is reliably installed inside the mixing cup 10 by engaging with the internal magnetic component 33 using a suction component 40. Furthermore, after the cup base 12 is fitted and fixed to the cup body 11, the suction component 40 adheres to the bottom wall of the cup body 11. The suction component 40 can magnetically attract the internal magnetic component 33 inside the mixing cup 10 with sufficient magnetic force to prevent the blade assembly 30 from falling out of the cup body 11 when not in use. It is securely locked inside the mixing cup 10, preventing it from flying out or falling off during user operation, thus achieving reliable positioning between the blade assembly 30 and the cup body 11.

[0048] Combination Figure 4 , Figure 5 By setting the lever 50, before the user needs to disassemble the blade assembly 30, pushing the lever 50 can cause the engaging assembly 40 to move along... Figure 4 The arrow shown points away from the inner magnetic element 33, increasing the distance between the magnetic poles of the attraction assembly 40 and the inner magnetic element 33. Specifically in Figure 4 The arrows in the diagram indicate the direction of movement of the magnetic attraction assembly when pushed by the joystick. Figure 5 The arrows in the diagram illustrate the respective directions of movement of the control lever 50 and the attraction component 40 during their linkage. According to Coulomb's law, the magnetic attraction between two magnets is inversely proportional to the square of the distance between them. Therefore, when the distance between the attraction component 40 and the inner magnetic component 33 increases, the magnetic attraction between them will rapidly weaken, eventually reaching a state where the magnetic attraction between the outer magnetic component 41 and the inner magnetic component 33 is imperceptible to the user. This reduces the resistance encountered during the removal of the blade assembly 30, allowing the user to easily remove the pulverizing device from the cup body 11 assembly, making the removal of the blade assembly 30 easier and more convenient.

[0049] Furthermore, in this embodiment, by installing the suction component 40 on the cup holder 12 and then installing it below the cup body 11 along with the cup holder 12, compared to directly installing the suction component 40 on the cup body 11, the assembler does not need to invert the cup body 11 for assembly, nor does it need to consider the installation difficulty of the heating plate at the bottom of the cup body 11, which requires too many fixing parts such as ferrules. This simplifies the assembly difficulty of the suction component 40 and reduces the number of fixing parts of the stirring cup 10. The assembly and cooperation of the suction component 40 and the cup body 11 are achieved by assembling the cup holder 12 and the cup body 11. Moreover, the control lever 50 is installed on the cup holder 12, making it easier to assemble the suction component 40 and the control lever 50 with the cup body 11. Moreover, the cup holder 12 is sleeved and fixed to the cup body 11. The cup holder 12 has an installation space, and the suction component 40 and the control lever 50 are uniformly set on the cup holder 12, reducing the fit tolerance between the two, so that the fit precision between the control lever 50 and the suction component 40 is high, the movement of the control lever 50 is smoother, there is no jamming, and the operation is less strenuous.

[0050] This utility model does not limit the specific structure of the suction component: such as Figure 4 As shown, the suction assembly 40 includes an outer magnetic component 41 that attracts the inner magnetic component 33 and a mounting bracket 42 with a mounting groove. The opening of the mounting groove faces the cup body 11. The outer magnetic component 41 is fixed to the mounting groove and adheres to the bottom wall of the cup body 11. The operating lever 50 pushes the mounting bracket 42 to move.

[0051] The attraction assembly 40 includes an outer magnetic component 41 and a mounting bracket 42. The mounting bracket 42 protects the outer magnetic component 41. Furthermore, the control lever 50 pushes the mounting bracket 42 to move, thereby moving the outer magnetic component 41. After long-term movement and engagement, direct wear on the outer magnetic component 41 is avoided, thus ensuring reliable magnetic attraction of the outer magnetic component 41. This allows the outer magnetic component 41 and the inner magnetic component 33 to reliably engage, forming a stable limiting effect on the tool assembly 30.

[0052] Of course, the attraction component 40 can be an external magnetic component 41, and the lever 50 can directly push the external magnetic component 41 to move, thus simplifying the structure.

[0053] Furthermore, this utility model does not limit the specific movement method of the suction component: such as Figure 1-7 As shown, in a preferred embodiment, the inner side of the bottom wall of the cup holder 12 is provided with a guide groove 121, and the suction assembly 40 includes a positioning block 43. The positioning block 43 is axially limited in the guide groove 121 by a fixing member and slides along the extension direction of the guide groove 121.

[0054] It is understood that when the attraction assembly includes an external magnetic component 41 and a mounting bracket 42, the positioning block 43 is either separately fixed or integrally protruding from the mounting bracket, or the mounting bracket 42 is slidably disposed in the guide groove 121 to form the positioning block 43. When the attraction assembly is an external magnetic component 41, the positioning block 43 is separately fixedly connected to the external magnetic component 41 or integrally formed.

[0055] like Figure 3 , 4 As shown, the fastener includes a screw 44, and the positioning block 43 is provided with a through hole 431, which is used in conjunction with... Figure 3 , 4 As shown in Figure 5, the screw 44 passes through the through hole 431 and locks into the guide groove 121. The through hole 431 extends in a strip shape along the sliding direction of the positioning block 43. More preferably, the fastener also includes a baffle 45 fixed to the groove end of the guide groove 121.

[0056] By setting a guide groove 121 and a positioning block 43, the positioning block 43 slides along the guide groove 121 to switch the suction assembly 40 between an engaging position with the inner magnetic component 33 and a disengaged position. When the user needs to remove the knife assembly 30, the operating lever 50 drives the suction assembly 40 away from the inner magnetic component 33, thereby unlocking the knife assembly 30. At the same time, the positioning block 43 is axially limited in the guide groove 121 by a fixing member, so that the suction assembly 40 and the cup seat 12 are both installed and positioned by means of the guide groove 121 of the cup seat 12, and a sliding limit is also formed. The structure is simple, the sliding is smooth, the operation of the push rod is effortless, and the disassembly of the knife assembly 30 is effortless.

[0057] A through hole 431 is provided in the positioning block 43, through which a screw 44 passes and locks into the guide groove 121, achieving axial positioning of the positioning block 43 and the guide groove 121. Simultaneously, the through hole 431 extends into a strip shape along the sliding direction of the positioning block 43, allowing the positioning block 43 to slide relative to the screw 44, and thus along the guide groove 121. The structure is simple. A baffle 45 is used as the fixing component to axially stop the positioning block 43 in the guide groove 121, preventing it from dislodging, while allowing it to slide smoothly along the guide groove 121 when pushed by the push rod.

[0058] Of course, it is understandable that the positioning block 43 can be a baffle 45, which can be individually glued or welded to the groove of the guide groove 121 to axially stop the positioning block 43 in the guide groove 121.

[0059] like Figure 4-7 As shown, preferably, a guide groove 121 is provided on the inner side of the bottom wall of the cup holder 12. The guide groove 121 extends radially along the cup holder 12. The suction assembly 40 moves along the guide groove 121 between positions near and away from the center of the cup holder 12. When force is applied to the lever, the moving direction of the suction assembly 40 is as follows: Figure 4 As indicated by the arrow.

[0060] Since the diameter of the blade assembly 30 is much smaller than the diameter of the cup body 11, there is a large proportion of installation space between the blade assembly 30 and the outer wall of the cup body 11. Correspondingly, this installation space is used to accommodate the suction assembly 40 and form the movement space of the suction assembly 40. There is no need to add an additional installation space structure for the stirring cup 10, and the outer diameter and volume of the stirring cup 10 will not be increased. It does not affect the structure and shape of the existing product.

[0061] like Figure 5 , 6As shown, more specifically, the control lever 50 is axially inserted into the cup holder 12 and moves along the cup holder 12. The control lever 50 is provided with a driving inclined surface 501, and the suction assembly 40 is provided with a passive inclined surface 401 that cooperates with the driving inclined surface. The driving inclined surface 501 extends obliquely along the moving direction of the control lever 50. More preferably, the main unit 20 is provided with a clearance opening that avoids the control lever 50. Figure 5 As shown, the attraction assembly 40 also includes a transmission block 46, and a passive inclined surface 401 is located on the transmission block 46.

[0062] The principle of movement of the suction component is: [The text abruptly ends here, likely due to an incomplete sentence or a formatting error.] Figure 5 , 4 As shown, when the stirring cup is placed on the workbench, the control lever 50 is lifted upwards by the workbench under the weight of the stirring cup. This causes the driving inclined surface 501 to engage with the transmission inclined surface 401, pushing the transmission block 46 to move radially. The transmission block 46 then drives the mounting bracket 42 to move radially, which in turn drives the outer magnetic component 41 to move radially away from its original position directly below the inner magnetic component 33. Preferably, as... Figure 4 As shown, by setting a reset spring 60, the attraction component 40 is automatically reset so that it can be attracted to the inner magnetic component 33, preventing the knife component from being thrown out or falling off during operation.

[0063] By inserting the lever 50 axially into the cup holder 12 and moving it axially along the cup holder 12, when the mixing cup 10 is placed on any table surface, the lever 50 can be automatically moved axially by the weight of the mixing cup 10 itself and the support of the table surface, eliminating the need for manual operation by the user and automating the attraction component 40. This also makes the removal and removal of the blade assembly 30 easier. When the lever 50 contacts the table surface, the driving inclined surface of the lever 50 engages with the passive inclined surface of the attraction component 40, causing the magnetic attraction component to move smoothly away from the internal magnetic component 33, making it easy to remove the blade assembly 30.

[0064] Preferably, the main unit 20 is provided with a clearance opening to avoid the control lever 50. This is to prevent the control lever 50 from shifting and causing the blade assembly 30 to unlock when the stirring cup 10 is installed on the main unit 20. Therefore, even when the stirring cup 10 is installed on the main unit 20, the reliable magnetic attraction between the attraction component 40 and the internal magnetic component 33 is still guaranteed, achieving more stable operation of the stirring blade 32.

[0065] Of course, in addition to setting a reset spring 60 to automatically reset the suction assembly 40, in other embodiments of this invention, the suction assembly 40 can also be fixedly connected to the control lever 50 so that the control lever can drive the suction assembly to reset.

[0066] like Figure 7 As shown, this utility model does not limit the cup holder structure; based on the installation of the aforementioned control lever, as... Figure 7 As shown, a limiting hole 123 is provided on the cup holder 12, and the operating lever is movably mounted in the limiting hole 123 and extends out of the cup holder 12 from the limiting hole 123. A reinforcing rib 124 is provided around the limiting hole 123.

[0067] In addition, combined Figure 6 , 7 Two sets of suction components 40 are provided, and a drive block 502 is provided at the top of the control lever 50. The drive block 502 has two drive inclined surfaces 501 corresponding to the two sets of suction components, so that the two sets of suction components 40 can be driven to move together by a single control lever 50. The structure is simple. The two sets of suction components ensure the smooth and multi-directional limiting of the tool setting component.

[0068] Furthermore, the arrangement of the control lever 50 in this invention is not limited to the above-mentioned axial insertion of it along the cup holder 12.

[0069] In other embodiments, the lever 50 is radially inserted into the cup holder 12 and moves radially along the cup holder 12. The lever 50 is provided with a pushing surface, and the suction assembly 40 is provided with a sliding surface that cooperates with the pushing surface. The pushing surface and the moving direction of the lever 50 are at an angle.

[0070] The joystick 50 is radially inserted into the cup holder 12 and moves radially along the cup holder 12. The joystick 50 can extend laterally from the cup holder 12 and be exposed to the user's view, making operation of the joystick 50 more intuitive and convenient. When the joystick 50 is pushed, the pushing surface of the joystick 50 engages with the sliding surface of the magnetic component, causing the magnetic component to move smoothly away from the inner magnetic element 33, allowing for easy removal of the knife assembly 30.

[0071] Of course, the movement of the suction component is not limited to the radial movement along the cup base. In fact, the suction component can be moved circumferentially along the cup base by the operation lever cooperating with the inclined surface of the suction component. It can be understood that when the circumferential movement of the suction component is misaligned with the inner magnetic component, the magnetic attraction is weakened, but the user can still easily remove the knife component.

[0072] Additionally, in a preferred embodiment, such as Figure 1 , 2 As shown, the bottom of the cup holder 12 is provided with a transmission cavity 122 into which the top of the electromagnetic drive device extends, and the attraction assembly 40 is disposed on the outer periphery of the transmission cavity 122. More preferably, the attraction assembly 40 includes an outer magnetic element 41 surrounding the outer periphery of the electromagnetic drive device, and an inner magnetic element 33 located on the outer periphery of the transmission disk 31. Preferably, the inner magnetic element 33 and the outer magnetic element 41 are arranged opposite to each other along the axial direction of the cup holder 12, so that the space inside the cup holder 12 is utilized more fully, and the structure of the outer magnetic element 41 and the electromagnetic drive device is compactly arranged.

[0073] By providing a transmission cavity 122 at the bottom of the cup holder 12 for the top of the electromagnetic drive device to extend into, when the stirring cup 10 is placed on the main unit 20, the electromagnetic drive device can fit closer to the bottom of the cup body 11, thus having a closer distance between it and the transmission disk 31, ensuring stronger magnetic attraction and driving force.

[0074] By surrounding the outer periphery of the electromagnetic drive device with the outer magnetic component 41, and by attaching the outer magnetic component 41 to the bottom wall of the cup body 11, installation interference between the outer magnetic component 41 and the electromagnetic drive device is prevented. Therefore, while ensuring the magnetic attraction force between the electromagnetic drive device and the transmission disk 31, the magnetic attraction force between the outer magnetic component 41 and the inner magnetic component 33 can also be ensured.

[0075] Furthermore, this utility model does not limit the specific structure of the electromagnetic drive device, such as... Figure 1 As shown, preferably, the electromagnetic drive device includes a motor 21 and a drive disk 22 driven by the motor 21. The drive disk 22 is located below the transmission disk 31 and drives the transmission disk 31 to rotate. Preferably, the top end of the drive disk 22 extends into the transmission cavity 122 to be close to the transmission disk, thereby achieving reliable driving.

[0076] Of course, the structure of the electromagnetic drive device is not limited to the one described above. In other embodiments, the electromagnetic drive device includes a stator and a coil winding wound around the stator. The coil winding is energized to generate a magnetic field to drive the transmission disk 31 to rotate. Preferably, the top end of the stator extends into the transmission cavity 122 to be close to the transmission disk, thereby achieving reliable drive.

[0077] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0078] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0079] The above are merely embodiments of this utility model and are 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.
