Description

Technical Field

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

[0002] The food processor includes a main unit and a blending cup assembly. The main unit includes a drive mechanism and a drive shaft. The blending cup assembly includes a blending cup, a lid assembly, and a blending element. The lid assembly includes a lid body and a locking / releasing structure. The blending element is fixed to the lid via the locking / releasing structure. The drive shaft extends into the blending cup and connects to the blending element. Subsequently, the locking / releasing structure releases the blending element. After release, the drive mechanism drives the drive shaft, which in turn rotates the blending element within the blending cup to process food.

[0003] In the aforementioned food processor, how to release or fix the mixing element through simple operation is a technical problem that needs to be solved. Utility Model Content

[0004] The purpose of this application is to disclose a cup lid assembly and a food processor. The cup lid assembly can release or fix the mixing element through a simple operation.

[0005] This application discloses a cup lid assembly. The cup lid assembly includes a lid body, an elastic element, and a retaining element. The lid body includes a connecting hole that penetrates the lid body in the thickness direction. The cup lid assembly includes a mounting portion, and the elastic element is located between the retaining element and the mounting portion. The retaining element includes a fixed portion and a release portion that are connected to each other. In the initial state, under the action of the elastic element, the fixed portion is located in the connecting hole to fix a stirring component, and the release portion is separated from the connecting hole. When the retaining element is pressed, the elastic element deforms, the fixed portion moves away from the connecting hole, and the release portion is located in the connecting hole to release the stirring component.

[0006] As described above, by providing the fixing part and the release part, the fixing part secures the stirring component at the connecting hole; pressing the retaining part causes the fixing part to move away from the connecting hole while the release part remains in the connecting hole, releasing the stirring component. Thus, the stirring component can be released or secured with a simple operation, making it convenient. Furthermore, in the above structure, only pressing the retaining part deforms the elastic element; during operation of the retaining part, there is no torque causing the lid to rotate relative to the stirring cup, eliminating the need for a fixing structure between the lid and the stirring cup to prevent rotation. Finally, the cup lid assembly achieves the fixing or release of the stirring component through the lid, elastic element, and retaining part, resulting in fewer parts, a simpler structure, fewer assembly steps, and lower cost.

[0007] In some embodiments, the cup lid assembly includes a guide mechanism under which the retainer moves linearly along the radial direction of the lid body.

[0008] As described above, the retainer moves linearly under the guidance of the guide mechanism, facilitating the operation of the retainer and the deformation of the elastic element. Furthermore, the linear movement of the retainer simplifies the structure, resulting in fewer parts, a simpler structure, fewer assembly steps, and lower costs for the cup lid assembly.

[0009] In some embodiments, the guiding mechanism includes a first guiding mechanism, which is a first groove extending radially toward the connecting hole along the cover; the retainer is provided with guide portions on opposite sides, and the guide portions on each side move along the corresponding groove wall of the first groove.

[0010] As described above, since the first groove extends radially along the cover and is a straight groove, the guide portions on opposite sides of the retainer move along the groove wall of the first groove. The elastic force direction of the elastic member and the movement direction of the retainer are both along a straight line. This makes the operation simpler and more convenient. The retainer is precisely guided and moves smoothly, which allows the fixing part and the releasing part to be accurately located at the connection hole.

[0011] In some embodiments, the cover includes the mounting portion located at the end of the first groove relative to the connecting hole.

[0012] As described above, the mounting part is located at the end of the first slide groove relative to the connecting hole. In this way, the first slide groove can promptly correct the movement of the retainer, thereby making the movement of the retainer smoother and more accurately guided.

[0013] In some embodiments, the groove wall of the first groove is symmetrical with respect to the axis of symmetry. When there is only one elastic element, the elastic element is located on the axis of symmetry, or the elastic element is parallel to the axis of symmetry and the distance between the elastic element and the axis of symmetry is less than or equal to 10 mm. When there are multiple elastic elements, the elastic elements are symmetrical with respect to the axis of symmetry.

[0014] As described above, regardless of whether the elastic element is located on the axis of symmetry, or the distance between it and the axis of symmetry is less than or equal to 10mm, or whether the elastic element is symmetrical with respect to the axis of symmetry, the force on the retaining element is always along the direction of the axis of symmetry, thus providing more precise guidance for the retaining element. Having only one elastic element contributes to the simplicity of the cup lid assembly's structure, lower cost, and reduces the number of steps required to install the elastic element.

[0015] In some embodiments, both the release part and the fixing part are holes, and the projected area of ​​the release part is larger than the projected area of ​​the fixing part on the radial plane of the cover.

[0016] As described above, since both the release part and the fixing part are holes, the structure of the retaining member is simple.

[0017] In some embodiments, the retainer includes a fixed release section forming the fixing portion and the release portion; the guide mechanism includes a second guide mechanism that guides the movement of the fixed release section.

[0018] As described above, since the second guide mechanism guides the movement of the fixed release section, and the fixed release section is used to form the fixed part and the release part, it can be ensured that one of the fixed part and the release part is accurately located in the connecting hole, while the other is away from the connecting hole, thus better realizing the fixing or releasing of the stirring component.

[0019] In some embodiments, the fixed release section includes two support arms, which are arranged opposite to each other to form the release part and the fixing part; there are two second guide mechanisms, each of which is a second slide groove disposed on the cover, and each support arm passes through a second slide groove to achieve the guiding.

[0020] As described above, since each support arm passes through a second groove to achieve the guiding effect, the guiding effect on the retaining member is better, and the fixing or release of the stirring member is better realized.

[0021] In some embodiments, the retainer includes an elastic element mounting portion, which, together with the lid, forms a mounting space for accommodating the elastic element. The lid assembly includes a notch; during movement of the retainer, the elastic element mounting portion engages with the sidewall of the notch.

[0022] As described above, during the movement of the retainer, the elastic mounting part and the notch sidewall of the notch are in clearance fit, and the notch can guide the movement of the retainer, making it easier for the retainer to move toward the connecting hole.

[0023] In some embodiments, the cover includes a column, and the connecting hole further extends through the column; the column includes a side wall opening that communicates with the connecting hole in a horizontal direction; the side wall opening is located on the movement path of the retainer.

[0024] As described above, since the sidewall opening is located on the movement path of the retainer, the sidewall opening can also guide the movement of the retainer, which is more conducive to the fixing part fixing the stirring component, or the release part releasing the stirring component. Furthermore, the connecting hole extends through the column, which helps the axis of the stirring component to coincide with the axis of the connecting hole, further facilitating the fixing part fixing the stirring component and the release part releasing the stirring component. Moreover, the sidewall of the sidewall opening can limit the retainer downwards in the axial direction of the column, thus ensuring that the retainer is located on the cover, guaranteeing that the release part or fixing part is accurately located in the connecting hole, thereby better releasing or fixing the stirring component.

[0025] This application also discloses a food processor. The food processor includes a main unit and a blending cup assembly. The blending cup assembly includes any of the aforementioned cup lid assemblies, a blending element, and a blending cup. The main unit includes a drive shaft; the drive shaft is connected to the blending element through the connecting hole.

[0026] As described above, the food processor includes at least the beneficial effects of the lid assembly.

[0027] In some embodiments, the main unit includes a main unit housing, a drive assembly, and a lifting assembly. The drive assembly includes the drive shaft, and the lifting assembly is connected to the drive assembly to drive the drive assembly to move up and down within the main unit housing. When the stirring element is released, the drive shaft drives the stirring element to move up and down within the stirring cup.

[0028] As described above, the stirring component is raised and lowered by the overall lifting and lowering of the drive assembly. Compared with raising and lowering only the drive shaft to raise and lower the stirring component, this avoids the drive shaft and other components from becoming loose due to lifting and lowering, which can cause noise and other issues. This ensures smoother drive shaft movement and lower noise in the food processor.

[0029] In some embodiments, the main unit includes a liftable support platform, the stirring cup assembly is located on the support platform, and the main unit housing includes an abutment portion; when the support platform is raised to its highest position, the abutment portion abuts against the retainer, such that a release portion of the retainer releases the stirring member.

[0030] As described above, the support platform rises, causing the abutment to abut against the retainer and driving the retainer to move until the stirring member is released. This automatically releases the stirring member, making the operation simpler. Attached Figure Description

[0043] 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.

[0044] 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 movements between 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.

[0045] See Figures 8 to 12 This application discloses a cup lid assembly 10. The cup lid assembly includes a lid body 1, an elastic element 2, and a retaining element 3. The lid body 1 includes a connecting hole 11. The connecting hole 11 penetrates the lid body 1 in the thickness direction. One function of the connecting hole 11 is to connect a stirring element 20 to a drive shaft so that the stirring element 20 can be ultimately fixed or released by the retaining element 3. Therefore, the structure of the connecting hole 11 is not limited, as long as it can achieve this function. In some embodiments, the cup lid assembly 10 also includes a shielding cover 4, which, together with the lid body 1, forms a receiving space. The elastic element 2 is located within the receiving space, and the retaining element 3 is located within the receiving space and extends out of the receiving space.

[0046] The cup lid assembly includes a mounting portion 14, and the elastic element 2 is located between the retaining element 3 and the mounting portion 14, thus the mounting portion 14 serves as the force-bearing point of the elastic element 2. Therefore, the mounting portion 14 can be provided on the lid body 1, on the cover 4, or on other parts of the cup lid assembly 10, as long as it can serve the aforementioned force-bearing point function. The structure of the elastic element 2 is not limited, and the way it abuts is not limited, as long as it can achieve the reset of the retaining element 3. The elastic element 2 in Figures 8 to 10 The spring in the middle can be a compression spring or a tension spring. Of course, the number of elastic elements 2 is not limited to one as shown in the figure.

[0047] The retaining member 3 includes a fixed part 31 and a releasing part 32 that are connected to each other. One function of the fixed part 31 is to fix the stirring member 20, and its structure is not limited to that shown. Figure 8 The two arc-shaped portions 311 shown are arranged in this configuration. In this embodiment, the fixing structure of the stirring member 20 is a step. More specifically, the stirring member 20 includes a first segment 201 and a second segment 202, which form a step so that the stirring member 20 can be fixed by the step. However, the fixing structure is not limited to a step. The fixing portion 31 is located in... Figure 8The diameter of the circle corresponding to the stirring element 20 is smaller than the diameter of the first segment 201 of the stirring element 20, which is smaller than the diameter of the fixing structure. The function of the release part 32 is to release the stirring element 20. For example, the diameter of the circle corresponding to the release part 32 is larger than the diameter of the second segment 202 of the stirring element 20 (larger than the diameter of the fixing structure). In short, the fixing part 31 prevents the stirring element 20 from falling, and the release part 32 allows the stirring element 20 to fall.

[0048] The following is a combination of Figures 8 to 12 The process of how the cup lid assembly 10 fixes and releases the stirring component 20 is described below:

[0049] Release agitator 20: See Figure 9 , Figure 10 and Figure 11 In its initial state, the retaining member 3, under the action of the elastic member 2, has the fixing part 31 located in the connecting hole 11 to fix the stirring member 20, and the releasing part 32 separated from the connecting hole 11. When the elastic member 2 is a compression spring, the compression spring applies a force towards the outside of the cover 1 in the direction of arrow R, thereby allowing the fixing part 31 to be located in the connecting hole 11 (at this time, the releasing part 32 is separated from the connecting hole 11), thus fixing the stirring member 20. In this embodiment, the diameter of the circle formed by the arcuate part 311 is smaller than the diameter of the stirring member 20, thus fixing the stirring member 20. Pressing the retaining member 3 in the direction of arrow r causes the elastic member 2 to deform (in the case of a compression spring, the deformation is that the elastic member 2 is compressed; in the case of a tension spring, the deformation is that the elastic member 2 is stretched), the fixing part 31 moves away from the connecting hole 11, and the releasing part 32 is located in the connecting hole 11 to release the stirring member 20. More specifically, because the release part 32 is larger than the diameter of the second section 202 of the agitator 20, the agitator 20 is no longer constrained by the release part 32. Under the action of the drive shaft 20030, the agitator 20 can rotate and / or move axially. For example, compared Figure 6 and Figure 7 The stirring element 20 can move axially to the bottom of the stirring cup. In this embodiment, when the stirring element 20 is not connected to the drive shaft 20030, the stirring element 20 will fall when released.

[0050] Fixing the stirring component 20: First, press the retaining member 3 to make the fixing part 31 leave the connecting hole 11, and the release part 32 is located in the connecting hole 11. After the fixing structure of the stirring component 20 is located in the connecting hole 11, release the retaining member 3. The force on the retaining member 3 is less than the elastic force of the elastic member 2. Under the action of the elastic force of the elastic member 2, the retaining member 3 moves along arrow R and returns to its original position. Figures 9 to 11 In this state, the fixing part 31 fixes the stirring component 20.

[0051] As described above, by providing the fixing part 31 and the release part 32, the fixing part 31 fixes the stirring element 20 at the connecting hole 11. Pressing the retaining member 3 causes the fixing part 31 to move away from the connecting hole 11 while the release part 32 remains in the connecting hole 11, releasing the stirring element 20. Thus, the stirring element 20 can be released or fixed through a simple operation, making the operation convenient. Furthermore, in the above structure, only pressing the retaining member 3 deforms the elastic member 2. During the operation of the retaining member 3, there is no torque causing the lid 1 to rotate relative to the stirring cup 30, eliminating the need for a fixing structure between the lid 1 and the stirring cup 30 to prevent rotation. Finally, the cup lid assembly achieves the fixing or release of the stirring element 20 through the lid 1, elastic member 2, and retaining member 3, resulting in fewer parts, a simpler structure, fewer assembly steps, and lower cost.

[0052] Based on the above process of releasing or fixing the stirring member 20, those skilled in the art can understand that the movement of the retaining member 3 is not limited, as long as when the stirring member 20 is released, the fixing part 31 leaves the connecting hole 11 and the releasing part 32 is located in the connecting hole 11, and when the stirring member 20 is fixed, the fixing part 31 is located in the connecting hole 11 and the releasing part 32 leaves the connecting hole 11.

[0053] See Figure 11 and Figure 12 as well as Figure 8 The cup lid assembly includes a guide mechanism, under the guidance of which the retaining member 3 moves linearly along the radial direction of the lid body 1. The structure of the guide mechanism is not limited, as long as it achieves the aforementioned function.

[0054] As described above, the retaining member 3 moves linearly under the guidance of the guiding mechanism, facilitating the operation of the retaining member 3 and the deformation of the elastic member 2. Furthermore, the linear movement of the retaining member 3 simplifies the structure, resulting in fewer parts, a simpler structure, fewer assembly steps, and lower costs for the cup lid assembly.

[0055] See Figure 8 , Figure 10 and Figure 11 The guiding mechanism includes a first guiding mechanism, which is a first groove 13 extending radially toward the connecting hole 11 along the cover 1. The configuration of the first groove 13 is not limited; for example, see [reference needed]. Figure 8 The cover 1 has two protruding sidewalls 12. The two sidewalls 12 are arranged in parallel to form the first slide groove 13. The retainer 3 has guide portions 33 on opposite sides, and the guide portions 33 on each side move along the corresponding groove wall (i.e., the sidewall 12) of the first slide groove 13.

[0056] As described above, since the first slide groove 13 extends radially along the cover 1 and is a straight slide groove, the guide portions 33 on opposite sides of the retainer 3 move along the groove wall of the first slide groove 13. The elastic force direction of the elastic member 2 and the movement direction of the retainer 3 are both in a straight line. In this way, the operation is simpler and more convenient. The retainer 3 is precisely guided and moves smoothly, which enables the fixing portion 31 and the releasing portion 32 to be precisely located at the connecting hole 11.

[0057] See Figure 8 and Figure 10 The cover 1 includes the mounting portion 14. The mounting portion 14 is located at the end of the first groove 13 relative to the connecting hole 11.

[0058] As described above, the mounting part 14 is located at the end of the first slide groove 13 relative to the connecting hole 11. In this way, the first slide groove 13 can promptly correct the movement of the retainer 3, thereby making the movement of the retainer 3 more stable and allowing it to be accurately guided.

[0059] See Figure 10 and Figure 11 The groove wall (side wall 12) of the first groove 13 is symmetrical with respect to the axis of symmetry L. When there is only one elastic element 2, the elastic element 2 is located on the axis of symmetry L. In some embodiments, the elastic element 2 may also be offset, in which case the elastic element 2 is parallel to the axis of symmetry L, and the distance between the elastic element 2 and the axis of symmetry L is less than or equal to 10 mm. In some embodiments, the elastic element 2 is a cylindrical compression spring, and the axis of the elastic element 2 coincides with the axis of symmetry L. Those skilled in the art will understand that when there are multiple elastic elements 2, the elastic elements 2 are symmetrical with respect to the axis of symmetry L. Those skilled in the art will understand that when the elastic element 2 is located on or symmetrical with respect to the axis of symmetry L, the mounting portion 14 may not be located at the end of the first groove 13 opposite to the connecting hole 11.

[0060] As described above, regardless of whether the elastic element 2 is located on the axis of symmetry L, or the distance between it and the axis of symmetry is less than or equal to 10mm, or whether the elastic element 2 is symmetrical with respect to the axis of symmetry L, the force on the retaining element 3 is always along the direction of the axis of symmetry L, thus providing more precise guidance for the retaining element 3. Having only one elastic element 2 contributes to the simplicity of the cup lid assembly 10's structure, lower cost, and reduced installation steps for the elastic element 2.

[0061] See Figure 8 and Figure 10 Both the release part 32 and the fixing part 31 are holes. On the radial plane of the cover 1, the projected area of ​​the release part 32 is larger than the projected area of ​​the fixing part 31. The method of forming the holes is not limited.

[0062] As described above, since both the release part 32 and the fixing part 31 are holes, the structure of the retaining member 3 is simple.

[0063] In some embodiments, the retainer 3 includes a fixed-release section forming the fixing portion 31 and the release portion 32. The structure of the fixed-release section is not limited to two separate support arms 34; the two support arms 34 may also be connected together, or the fixing portion 31 and the release portion 32 may be formed on a plate-like structure. The guiding mechanism includes a second guiding mechanism that guides the movement of the fixed-release section.

[0064] As described above, since the second guide mechanism guides the movement of the fixed release section, and the fixed release section is used to form the fixed part 31 and the release part 32, it can be ensured that one of the fixed part 31 and the release part 32 is accurately located in the connecting hole 11, while the other is away from the connecting hole 11, thus better realizing the fixing or releasing of the stirring member 20.

[0065] See Figure 8 and Figure 10 The retaining member 3 includes two support arms 34, each of which is arranged opposite to the other to form the release part 32 and the fixing part 31. The guiding mechanism includes a second guiding mechanism. There are two second guiding mechanisms, each being a second groove 15 disposed on the cover 1. See also... Figure 10 Each of the aforementioned support arms 34 passes through a second slide groove 15 to achieve the guiding function. The two support arms 34 are not limited to the separated state shown in the figure, as long as they have a portion that passes through the second slide groove 15.

[0066] As described above, since each support arm 34 passes through a second groove 15 to achieve the guiding effect, the guiding effect on the retaining member 3 is better, and the fixing or release of the stirring member 20 is better realized.

[0067] See Figure 8 and Figure 10 The retaining member 3 includes an elastic element mounting portion 35, which, together with the cover body 1, forms a mounting space to accommodate the elastic element 2. The cup lid assembly 10 includes a notch 16. See also... Figure 1 and Figure 8Both the lid 1 and the cover 4 are provided with notches 16. In some embodiments, only one of them needs to have the notch 16. Of course, the notch 16 can also be provided on other parts of the cup lid assembly 10. During the movement of the retainer 3, the elastic mounting part 35 is in clearance fit with the notch sidewall 161 of the notch 16. In the initial state, the elastic mounting part 35 extends out of the notch 16. After extending, the consumer can see the elastic mounting part 35 and can apply a force to the elastic mounting part 35 to make the retainer 3 move.

[0068] As described above, during the movement of the retainer 3, the elastic mounting part 35 and the notch sidewall 161 of the notch 16 are in clearance fit, so the notch 16 can guide the movement of the retainer 3, making it easier for the retainer 3 to move toward the connecting hole 11.

[0069] See Figure 8 , Figure 11 and Figure 12 The cover 1 includes a column 17, and the connecting hole 11 further penetrates the column 17. The column 17 includes a side wall opening 171 that communicates with the connecting hole in a horizontal direction. The side wall opening 171 is located on the movement path of the retainer 3, thus, see Figure 11 and Figure 10 In the initial state, the fixing part 31 is located within the side wall opening 171; see also Figure 12 When the retainer 3 is pressed, the fixing part 31 moves away from the side wall opening 171.

[0070] As described above, since the side wall opening 171 is located on the movement path of the retainer 3, the side wall opening 171 can also guide the movement of the retainer 3, which is more conducive to the fixing part 31 fixing the stirring member 20, or the release part 32 releasing the stirring member 20. Furthermore, the connecting hole 11 also penetrates the column 17, which is conducive to the alignment of the axis of the stirring member 20 with the axis of the connecting hole 11, further facilitating the fixing part 31 fixing the stirring member 20 and the release part 32 releasing the stirring member 20. Moreover, the side wall of the side wall opening 171 can limit the retainer 3 downward in the axial direction of the column 17, thus ensuring that the retainer 3 is located on the cover 1, guaranteeing that the release part 32 or the fixing part 31 is accurately located in the connecting hole 11, thereby better releasing or fixing the stirring member 20.

[0071] See Figure 1 , Figure 2 , Figures 4 to 7This application discloses a food processor. The food processor includes a main unit 200 and a blending cup assembly 100. The blending cup assembly 100 includes any of the aforementioned cup lid assemblies 10, a blending element 20, and a blending cup 30. In this application, the blending cup 30 includes an outer cup 301 and an inner cup 302 located within the outer cup 301. The main unit includes a drive shaft 20030. The drive shaft 20030 is connected to the blending element 20 through the connecting hole 11. The connection through the connecting hole 11 means that the blending element 20 and the drive shaft 20030 are connected as a whole through the connecting hole. It can be that both the drive shaft 20030 and the blending element 20 pass through the connecting hole 11, or one of them passes through the connecting hole 11 to achieve the connection, and it is not limited to this. After connection, when it is necessary to release the blending element 20, the retaining member 3 releases the blending element 20. After the drive shaft 20030 is connected to the stirring element 20 and the stirring element 20 is released by the fixing part 31, the drive shaft 20030 can drive the stirring element 20 to rotate inside the mixing cup 30 to process food. The stirring element 20 can be released by the consumer pressing the retaining part 3, or by the method described later.

[0072] As described above, the food processor includes at least the beneficial effects of the lid assembly 10.

[0073] See Figures 1 to 7 The main unit 200 includes a main unit housing 2002, a drive assembly 2003, and a lifting assembly 2004. The drive assembly 2003 includes a drive shaft 20030, a drive motor 20031, and a gearbox assembly 20032. The input end of the gearbox assembly 20032 is connected to the drive motor 20031. The output end of the gearbox assembly 20032 is connected to the drive shaft 20030. The lifting assembly 2004 is connected to the drive assembly 2003. In this application, the lifting assembly 2004 includes a lifting motor 20041, a screw 20042, and a guide mechanism. Thus, the lifting assembly 2004 drives the drive assembly 2003 (drive shaft 20030, drive motor 20031, and gearbox assembly 20032) to move up and down within the main unit housing 2002. When the stirring element 20 is released, the drive shaft 20030 drives the stirring element 20 to move up and down within the stirring cup 30. The principle by which the lifting assembly 2004 drives the lifting assembly 2003 is the same as the working principle of the lead screw, and will not be repeated here. See also Figure 2 , Figure 6 and Figure 7 The main housing 2002 includes a base housing 20021, a lower head housing 20022, and a upper head housing 20023. The upper head housing 20023, the lower head housing 20022, and the base housing 20021 form a cavity to accommodate the drive assembly 2003. Figure 6 and Figure 7 , Figure 6 The diagram shows that the drive assembly 2003 has not yet descended, and the stirring element 20 connected to the stirring shaft 20030 is located at the top of the stirring cup 30. Figure 7 The diagram illustrates the downward movement of the drive assembly 2003, which in turn causes the stirring element 20, connected to the drive shaft 20030, to descend to the bottom of the stirring cup 30.

[0074] As described above, the stirring component 20 is raised and lowered by the overall lifting and lowering of the drive assembly 2003. Compared with raising and lowering only the drive shaft 20030 to raise and lower the stirring component 20, this avoids the drive shaft 20030 from becoming loose or generating noise due to the lifting and lowering of other components, ensuring smoother movement of the drive shaft 20030 and lower noise in the food processor.

[0075] See Figure 4 The main unit 200 includes a liftable support platform 2001. The stirring cup assembly 100 is located on the support platform 2001. The main unit housing 2002 includes a stop portion 20020; when the support platform 2001 is raised to its highest position, the stop portion 20020 abuts against the retaining member 3, so that the release portion 32 of the retaining member 3 releases the stirring member 20. The lifting and lowering methods of the support platform 2001 include the following two: 1) The support platform 2001 does not rotate during lifting and lowering. After the drive shaft 20030 is connected to the stirring member 20, as the support platform 2001 continues to rise, the stop portion 20020 and the retaining member 3 move through an inclined surface engagement until the stirring member 20 is released. Of course, during the descent of the support platform 2001, the cooperation relationship between the retaining member 3 and the elastic member 2 is described in the aforementioned section on the release and fixing process of the stirring member 20; 2) The support platform 2001 rotates while lifting and lowering. See Figure 4 The abutment portion 20020 is inclined relative to the circumference of the cover 1. Thus, the distance between the abutment portion 20020 and the drive shaft 20030 gradually decreases towards the connecting hole 11. This ensures that after the drive shaft 20030 connects to the stirring member 20, the abutment portion 20020 remains in contact with the retaining member 3 as the support platform 2001 continues to rise, causing the retaining member 3 to move until the stirring member 20 is released. Regardless of the method, the abutment portion 20020 abuts against the retaining member 3 only after the drive shaft 20030 connects to the stirring member 20. During the descent of the support platform 2001, the force exerted by the abutment portion 20020 on the retaining member 3 is less than the elastic force exerted by the elastic member 2 on the retaining member 3. Thus, as the support platform 2001 descends, the elastic force of the elastic member 2 eventually causes the fixing portion 31 to be located at the connecting hole 11, while the releasing portion 32 moves away from the connecting hole 11.

[0076] As described above, the support platform 2001 rises so that the abutment part 20020 abuts against the retaining member 3, thereby driving the retaining member 3 to move radially along the cover body 1 until the stirring member 20 is released. Thus, the stirring member 20 is automatically released, making the operation simpler.
