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, two retaining elements, and an operating element. The lid body includes a connecting hole that penetrates the lid body in the thickness direction. Each retaining element is connected to the lid body via a pivot structure. Each retaining element includes a fixing portion and a connecting portion located on both sides of the pivot structure. Each connecting portion is connected to the operating element. When the operating element is operated, the operating element pushes the retaining element to rotate, the elastic element deforms, and the two fixing portions open up until a stirring element can be released. When the operating element is not operated, the two fixing portions close up at the connecting hole under the action of the elastic element to fix the stirring element, and the operating element resets under the action of the elastic element.

[0006] As described above, when the operating member is operated, it pushes the retaining member to rotate, causing the elastic member to deform and the two fixing parts to open until the stirring member can be released. When the operating member is not operated, the two fixing parts close together at the connecting hole under the action of the elastic member to fix the stirring member, and the operating member resets under the action of the elastic member. Thus, the stirring member can be released or fixed with a simple operation, making operation convenient. Furthermore, in the above structure, the stirring member can be released simply by pressing the operating member. During the operation of the operating member, there is no torque that causes the lid to rotate relative to the stirring cup, and no fixing structure to prevent rotation is needed between the lid and the stirring cup. Finally, the cup lid assembly achieves the fixing or release of the stirring member through the lid, elastic member, retaining member, and operating member, resulting in fewer parts, a simpler structure, fewer assembly steps, and lower cost.

[0007] In some embodiments, when the two connecting parts are closed together, the two fixing parts are open; when the two connecting parts are open, the two fixing parts are closed together; or, when the two connecting parts are closed together, the two fixing parts are closed together; when the two connecting parts are open, the two fixing parts are open.

[0008] As described above, any of the aforementioned methods can synchronize the movement of the two fixing parts. Ultimately, the degree to which the two fixing parts retract or open is well matched with the shape of the fixing structure of the stirring component. The two fixing parts can more accurately fix or release the stirring component. For example, it is less likely that one fixing part will support the step while the other fixing part has not yet supported the step, thus preventing the two fixing parts from accurately clamping the stirring component. Alternatively, the degree to which one fixing part opens relative to the connecting hole can allow this side of the stirring component to be released, while the degree to which the other fixing part opens relative to the connecting hole prevents the other side of the stirring component from being released.

[0009] In some embodiments, both ends of the elastic member are connected to the connecting portion. When the operating member is operated, the operating member moves toward the cover, causing the elastic member to deform and push the retaining member to rotate, thereby opening the fixing portions apart. When the operating member is not operated, the elastic member pushes the retaining member to rotate, and the operating member moves away from the cover under the push of the retaining member.

[0010] As described above, the elastic element is connected to the connecting part at both ends, allowing the operating member to move towards the lid to release the stirring element, or to move away from the lid to fix the stirring element. This simple operation allows for easy release or fixation of the stirring element. Furthermore, because the operating member moves towards or away from the lid, when the lid assembly is assembled onto the main unit of the food processor, the corresponding structure on the main unit can directly abut the operating member, simplifying the main unit's structure.

[0011] In some embodiments, each of the connecting portions includes a connecting portion slope inclined to a horizontal plane, and two connecting portion slopes are symmetrically distributed; the operating member includes a pushing portion corresponding to each of the connecting portion slopes.

[0012] As described above, the inclined surfaces of the pushing part and the connecting part are engaged, and the inclined surfaces of the connecting part are symmetrical. This ensures that the two connecting parts move synchronously, and consequently, the two fixing parts move synchronously. Ultimately, this allows for more precise fixing or release of the stirring component.

[0013] In some embodiments, the angle between the inclined surface of the connecting portion and the horizontal plane is α, where 30 degrees ≤ α ≤ 60 degrees.

[0014] As described above, the setting of 30 degrees ≤ a ≤ 60 degrees facilitates the operation member to push the retaining member to deform the elastic member, and also facilitates the elastic force of the elastic member to push the retaining member to reset.

[0015] In some embodiments, the cup lid assembly includes a shielding cover that forms a receiving cavity with the lid body, and the retaining member, the elastic member, and the operating member are located within the receiving cavity; the shielding cover includes a shielding cover through hole that has the same through direction as the connecting hole, and the operating member is clearance-fitted with the shielding cover through hole and extends out of the cup lid assembly from the shielding cover through hole.

[0016] As described above, since the through-hole of the shielding cover has the same through-hole direction as the connecting hole, and the operating member is clearance-fitted with the through-hole of the shielding cover and extends from the cup lid assembly through the through-hole of the shielding cover, the main unit does not need to have a structure for abutting the operating member. Instead, the operating member can be operated by directly abutting the operating member with a part of the main unit, thus simplifying the structure of the main unit.

[0017] In some embodiments, one of the cover and the operating component is provided with three guide posts, the lines connecting the beginning and end of the three guide posts forming a triangle; the other of the cover and the operating component is provided with mounting holes, the guide posts being inserted into the corresponding mounting holes.

[0018] As described above, since the lines connecting the beginning and end of the three guide pillars form a triangle, the mounting holes are inserted into the guide pillars one by one. This guides the movement of the operating component, which is beneficial for the precise cooperation between the operating component and the retaining component, thereby better enabling the fixing part to fix or release the stirring component.

[0019] In some embodiments, the pivot structure includes a pivot hole disposed in one of the retainer and the cover, and a pivot disposed in the other, the pivot being located within the pivot hole.

[0020] As described above, the rotating shaft is located inside the rotating shaft hole, and the hole and shaft are matched to ensure smooth and more stable rotation of the component.

[0021] In some embodiments, the cover includes a column, and the connecting hole further penetrates the column; the column includes a side wall opening communicating with the connecting hole; when the fixing part is in a retracted state and the stirring member is fixed, the fixing part passes through the side wall opening and is located within the connecting hole; when the fixing part is in an open state and the stirring member is released, the fixing part is located within the side wall opening.

[0022] As described above, when the fixing part is closed and the stirring component is fixed, the fixing part passes through the side wall opening and is located within the connecting hole. When the fixing part is opened and the stirring component is released, the fixing part is located within the side wall opening. This allows the side wall opening to guide the movement of the retaining component, making it easier for the fixing part to fix or release the stirring component. Simultaneously, the side wall of the side wall opening can limit the retaining component downwards along the axial direction of the column, further ensuring better release or fixation of the stirring component. Furthermore, the connecting hole extends through the column, facilitating the alignment of the stirring component's axis with the axis of the connecting hole, thus further facilitating the fixing part's fixation or release of the stirring component.

[0023] 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, and the main unit includes a drive shaft; the drive shaft is connected to the blending element through the connecting hole.

[0024] As described above, the food processor includes at least the beneficial effects of the lid assembly.

[0025] 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.

[0026] 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.

[0027] 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 operating member, so that the retaining portion of the retainer releases the stirring member.

[0028] As described above, the support platform rises, causing the abutment to abut against the operating component, which in turn drives the retaining component to rotate around the rotating shaft structure, causing the fixing part to open until the stirring component is released. Thus, the stirring component is automatically released, making the operation simpler. Attached Figure Description

[0050] 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.

[0051] 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.

[0052] See Figures 8 to 10 , Figure 12 , Figure 16 and Figure 17 This application discloses a first type of cup lid assembly 10. Figure 19 A second type of cup lid assembly 10 is disclosed, which includes a lid body 1, an elastic element 2, two retaining elements 3, and an operating element 4. In some embodiments, the cup lid assembly 10 further includes a shielding cover 5. The shielding cover 5 and the lid body 1 form a receiving space. The elastic element 2 and the retaining elements 3 are located within the receiving space, and the operating element 4 is located within the receiving space and extends out of the cup lid assembly 10. Figure 1 In the first type of cup lid assembly shown, the operating member 4 extends from the top of the cup lid assembly 10 into the receiving space in a vertical direction (perpendicular to the lid body 1). Figure 19 In the second type of cup lid assembly 10 shown, the operating member 4 extends radially out of the cup lid assembly 10 along the lid body 1. The lid body 1 includes a connecting hole 11 that penetrates the lid body 1 in the thickness direction. One function of the connecting hole 11 is to connect the stirring member 20 to the drive shaft so that the stirring member 20 can ultimately be fixed or released by the retaining member 3. Therefore, the structure of the connecting hole 11 is not limited, as long as it can achieve this function.

[0053] See Figure 9 , Figure 10 , Figure 12 and Figure 19Each retaining member 3 is connected to the cover 1 via a pivot structure 310, including a fixing part 31 and a connecting part 32 located on both sides of the pivot structure 310. Each connecting part 32 is connected to the operating member 4, and the connection method is not limited, as long as the operating member 4 can push the retaining member 3 and deform the elastic member 2 to ultimately release the stirring member 20; the retaining member 3 and the elastic member 2 cooperate to allow the operating member 4 to reset and fix the stirring member 20. Figure 14 and Figure 15 The connection between the connecting part 32 and the operating member 4 is shown to be that the retaining member 3 abuts against the operating member 4. Figures 19 to 21 The diagram illustrates that the connecting part 32 of the retainer 3 and the operating part 4 are connected to the guide post 320 via the slide groove 41. The connection state between the two retainers 3 and the cover 1 via the rotating shaft structure 310 is not limited; the first case is as follows... Figure 9 , Figure 10 and Figure 12 as well as Figure 19 As shown, each of the retaining members 3 is assembled to the cover 1 via a pivot structure 310, and the two retaining members 3 are separate; the second case is as follows. Figure 18 As shown, the two retainers 3 are connected in a cross shape by a pivot structure 310.

[0054] When the operating element 4 is operated, it pushes the retaining element 3 to rotate, the elastic element 2 deforms, and the two fixing parts 31 open up until the stirring element 20 can be released. Operation can be achieved by the consumer pressing the element, or by the abutment on the main unit as described later. When the operating element 4 is not operated, the two fixing parts 31 close up at the connecting hole 11 under the action of the elastic element 2, and the operating element 4 resets under the action of the elastic element 2. "Not operated" includes one of the following situations: 1) pressing the operating element 4 and releasing it (in this case, the operating element 4 is only subjected to the elastic force of the elastic element 2 and is not operated); 2) not pressing the operating element 4; 3) when the cup lid assembly 10 and the support platform 2001 descend, the abutment between the main unit and the operating element gradually loosens, and the elastic element 2 causes the operating element 4 to gradually reset. More specifically, see [link to relevant documentation]. Figures 8 to 10 , Figure 12 , Figure 16 and Figure 17 The process of releasing and securing the stirring element 20 in the first type of cup lid assembly shown is described below:

[0055] Before describing the process of releasing and securing the agitator 20, let's first introduce one structure of the agitator 20. The agitator 20 includes a securing structure. More specifically, the securing structure of the agitator 20 includes a first segment 201 and a second segment 202. The first segment 201 and the second segment 202 form a step. Those skilled in the art will understand that the securing structure is not limited to a step.

[0056] Release of agitator 20: See the state where agitator 20 is fixed by fixing part 31. Figure 9 , Figure 10 and Figure 11 At this point, the positional relationship between the operating element 4 and the retaining element 3 can also be found in [reference needed]. Figure 14 With the mixing element 20 fixed: the step formed by the first segment 201 and the second segment 202 is supported by the fixing part 31, and the first segment 201 is clamped by the two fixing parts 31. Figure 14 In the indicated state, pressing down on the operating member 4 causes the two retaining members 3 to rotate and the elastic member 2 to deform (here, the deformation is compression) through the cooperation of the pushing part 42 and the connecting part 32 of the operating member 4. Thus, the two connecting parts 32 move along... Figure 17 The arrows m shown converge towards each other, while the fixing part 31 moves along... Figure 17 and Figure 9 The arrows N shown open towards each other until the fixing part 31 releases the stirring element 20. (See the image for the open state of the fixing part 31.) Figure 12 , Figure 13 and Figure 17 ,exist Figure 12 and Figure 13 In the indicated state, the stirring element 20 is released. In this embodiment, the width of the opening of the fixing part 31 is greater than the diameter of the fixing part (the diameter of the first segment 201 and the diameter of the second segment 202), so it no longer supports the step and no longer clamps the stirring element 20. Thus, when the drive shaft 20030 is connected to the stirring element 20, the stirring element 20 can rotate under the drive of the drive shaft 20030 (either just rotates, or it both rotates and moves along the axis of the stirring cup 30 within the stirring cup 30).

[0057] Fixed stirring component 20: The fixing part 31 opens, and the stirring component 20 is placed at the connecting hole 11. In this embodiment, the first segment 201 and the second segment 202 of the stirring component 20 are inserted into the connecting hole 11. See then... Figure 16 Without operating the aforementioned operating member 4, under the action of the elastic member 2 (the elastic member 2 moves from...), Figure 17 During the process of restoring the deformed state to its natural state, the elastic force of the elastic element 2 will cause the retaining element 3 to rotate around the rotating shaft structure 310, and the two connecting parts 32 along... Figure 16 The arrows n shown are spread apart, and correspondingly, the rotation of the retainer 3 around the pivot structure 310 will cause the two fixed parts 31 to move along... Figure 16 and Figure 9 The arrows M shown converge towards each other until the stirring element 20 is fixed. In this embodiment, the fixed state of the stirring element 20 is shown in [reference needed]. Figure 9 , Figure 10 and Figure 11The two fixing parts 31 clamp the first segment 201 and support the step. Correspondingly, under the action of the elastic member 2, the two connecting parts 32 open, causing the operating member 4 to be reset. Figure 15 and Figure 14 It can be seen that operating component 4 will... Figure 15 The state shown moves upward to Figure 14 The state shown.

[0058] for Figure 19 The structure of the second type of cup lid assembly 10 and the stirring element 20 shown can be compared with... Figure 8 , Figure 11 and Figure 13 The agitator 20 shown has the same structure. The process of releasing and fixing the agitator 20 is briefly described below:

[0059] Release the agitator 20: Figure 19 The diagram illustrates that the stirring component 20 is fixed, and the state between the two fixing parts 31 is shown in the figure. Figure 19 In addition, you can also see Figure 20 See also Figure 19 and combined Figure 21 When the operating member 4 is operated, the operating member 4 moves radially toward the connecting hole 11 along the cover 1 (see...). Figure 19 When the direction of the middle arrow (f) is met, the elastic element 2 deforms, and the retaining element 3 rotates about the rotating shaft structure 310 so that the two fixed parts 31 open up to each other (opening direction as shown in the middle arrow). Figure 19 and Figure 21 (As indicated by the middle arrow r) until the stirring element 20 can be released. See the description of the state in which the stirring element 20 can be released. Figure 21 The fixing part 31 is shown in an open state. In this state, the distance the fixing part 31 is open is greater than the diameter of the fixing structure. Thus, the step of the stirring member 20 is no longer supported by the fixing part 31 and is released. After release, when the stirring member 20 is connected to the drive shaft 20030, the stirring member 20 can rotate under the drive of the drive shaft 20030 (either just rotates, or it both rotates and moves along the axis of the stirring cup 30 within the stirring cup 30). In this embodiment, when the stirring member 20 is not connected to the drive shaft 20030, the stirring member 20 will fall after being released.

[0060] Fixed stirring component 20: First along Figure 19 and Figure 21 Press the operating member 4 in the direction of arrow f, and the fixing parts 31 will open relative to each other in the direction of arrow r. Insert the stirring member 20 into the connecting hole 11. See also Figure 19 and Figure 20 Subsequently, the operating member 4 is released (after release, the operating member 4 is no longer operated). Under the elastic force of the elastic member 2, the operating member 4 moves along... Figure 19 andFigure 20 The movement is in the direction of arrow F (i.e., the outer side of the cup lid assembly). That is, when the operating member 4 is not operated, the two fixing parts 31 move along the elastic member 2. Figure 19 and Figure 20 The movement in the direction of the center arrow R causes the components to converge at the connecting hole 11, thus clamping the stirring element 20 together. Simultaneously, the operating element 4 resets under the action of the elastic element 2. When the stirring element 20 is clamped, the step formed by the first segment 201 and the second segment 202 is supported by the fixing part 31, and the first segment 201 is clamped by the two fixing parts 31. The fixed state of the stirring element 20 can be seen in [reference needed]. Figure 19 .

[0061] Technicians will understand that the aforementioned elastic element 2 is a compression spring; however, elastic element 2 can also be a tension spring. In this case, for Figure 19 The second type of cup lid assembly 10 shown has a mounting part 14 that needs to be positioned from... Figure 14 The current position is changed to the opposite position. That is, when the elastic element 2 is a compression spring, pressing the operating element 4 causes it to move in the direction of arrow f, releasing the stirring element 20, and the elastic element 2 deforms into compression; when the elastic element 2 is a tension spring, when the operating element 4 moves in the direction of arrow f to release the stirring element 20, the elastic element 2 deforms into extension. For Figure 8 The first type of cup lid assembly 10 shown, when the operating member 4 is operated, causes the elastic member 2 to deform and elongate, thereby releasing the stirring member 20. When the operating member 4 is released (i.e., the operating member 4 is not operated), the elastic member 2 returns to its natural state so that the operating member 4 resets.

[0062] As described above, when the operating member 4 is operated, it pushes the retaining member 3 to rotate, causing the elastic member 2 to deform, and the two fixing parts 31 to open until the stirring member 20 can be released. When the operating member 4 is not operated, the two fixing parts 31, under the action of the elastic member 2, close together at the connecting hole 11 to fix the stirring member 20, and the operating member 4 returns to its original position under the action of the elastic member 2. Thus, the stirring member 20 can be released or fixed with a simple operation, making operation convenient. Furthermore, in the above structure, the stirring member 20 can be released simply by pressing the operating member 4. During the operation of the operating member 4, there is no torque that causes the cover 1 to rotate relative to the stirring cup 30, and there is no need to provide a fixing structure between the cover 1 and the stirring cup 30 to prevent rotation. Finally, the cup lid assembly achieves the fixing or release of the stirring member 20 through the cover 1, elastic member 2, retaining member 3, and operating member 4, resulting in fewer parts, a simpler structure, fewer assembly steps, and lower cost.

[0063] See Figure 9 ,Figure 10 , Figure 12 , Figure 16 and Figure 17 The first type of cup lid assembly 10 shown and Figures 19 to 21 In the second type of cup lid assembly 10 shown, along the two connecting portions 32 Figure 17 The direction of the middle arrow m and Figure 21 When the two fixing parts 31 converge towards each other in the direction of the middle arrow n, they move along... Figure 17 The direction of the middle arrow N and Figure 19 and Figure 21 The two connecting portions 32 are spread apart in the direction of the middle arrow r to release the stirring element 20; along the direction of the middle arrow r. Figure 16 The middle arrow n and Figure 20 When the two fixing parts 31 are spread apart in the direction of the middle arrow m, the two fixing parts 31 are along Figure 16 The middle arrow M and Figure 20 The middle arrow R points towards each other to secure the stirring element 20.

[0064] See Figure 18 Using pliers to illustrate this working principle, when the two connecting parts 32 are closed together, the two fixing parts 31 are also closed together to secure the stirring member 20; when the two connecting parts 32 are open, the two fixing parts 31 are open to release the stirring member 20. Specifically, the directions of the opening of the connecting parts 32 and the fixing parts 31 are shown below. Figure 18 As indicated by the middle arrows M and m, the directions in which the connecting parts 32 and the fixing parts 31 retract are shown in the figure. Figure 18 As indicated by the middle arrows n and N. At this point, the cooperation method between the elastic element 2 and the operating element 4 can also refer to the aforementioned cooperation method, and will not be repeated here. Of course, it is not limited to this method.

[0065] As described above, any of the aforementioned methods can synchronize the movement of the two fixing parts 31. Ultimately, the degree to which the two fixing parts 31 close or open is well matched with the shape of the fixing structure of the stirring member 20. The two fixing parts 31 can more accurately fix or release the stirring member 20. For example, it is less likely that one fixing part 31 will support the step while the other fixing part 31 has not yet supported the step, thus preventing the two fixing parts 31 from accurately clamping the stirring member 20. Alternatively, the degree to which one fixing part 31 opens relative to the connecting hole 11 can allow this side of the stirring member 20 to be released, while the degree to which the other fixing part 31 opens relative to the connecting hole 11 prevents the other side of the stirring member 20 from being released.

[0066] See Figure 16 , Figure 17 , Figure 10 and Figure 12Both ends of the elastic element 2 are respectively connected to the connecting part 32. When the operating element 4 is operated, the operating element 4 moves towards the cover 1 in an axial direction parallel to the connecting hole. That is, the operating element 4... Figure 14 Move along the downward direction to Figure 15 As shown, the connecting part 32 is along Figure 17 The movement of the middle arrow m causes the operating member 4 to deform the elastic member 2 and push the retaining member 3 to rotate about the rotating axis structure 310, thereby realizing the fixing part 31 along... Figure 17 The parts are spread apart in the N-direction. When the operating member 4 is not operated, the elastic member 2 pushes the retaining member 3 to rotate. Under the push of the retaining member 3, the operating member 4 moves away from the cover 1 in a direction parallel to the axial direction of the connecting hole. That is, when the external force on the operating member 4 is less than the elastic force of the elastic member 2, the elastic force of the elastic member 2 causes the retaining member 3 to rotate, and the fixing part 31 moves along... Figure 16 The middle arrow M converges, and the connecting part 32 follows the direction of the middle arrow M. Figure 16 The middle arrow n opens in the direction of the arrow, thus, the operating element 4 moves along... Figure 15 The state shown moves upward to Figure 16 The state shown.

[0067] As described above, the elastic element is connected to the connecting part 32 at both ends, allowing the operating member 4 to move towards the lid 1 to release the stirring member 20, or to move away from the lid 1 to fix the stirring member 20. This simple operation allows for easy release or fixation of the stirring member 20. Furthermore, because the operating member 4 moves towards or away from the lid 1, when the lid assembly 10 is assembled onto the main unit of the food processor, the corresponding structure on the main unit can directly abut against the operating member 4, simplifying the main unit's structure.

[0068] See Figures 14 to 17 Each of the connecting portions 32 includes a connecting portion inclined surface 321 inclined to a horizontal plane, and two connecting portion inclined surfaces 321 are symmetrically distributed; the operating member 4 includes a pushing portion 42 corresponding one-to-one with each of the connecting portion inclined surfaces 321. The pushing portion 42 can be an inclined surface, or it can be like... Figure 14 and Figure 15 As shown, it is not an inclined plane.

[0069] As described above, the pushing part 42 cooperates with the inclined surface 321 of the connecting part, and the inclined surface 321 of the connecting part is symmetrical. This ensures that the two connecting parts 32 move synchronously, and consequently, the two fixing parts 31 move synchronously. Ultimately, the stirring member 20 can be fixed or released more accurately.

[0070] In some embodiments, the angle between the inclined surface 321 of the connecting portion and the horizontal plane is α, 30 degrees ≤ α ≤ 60 degrees, for example, 30 degrees, 32 degrees, 35 degrees, 38 degrees, 40 degrees, 42 degrees, 45 degrees, 47 degrees, 50 degrees, 53 degrees, 55 degrees, 58 degrees or 60 degrees.

[0071] As described above, the setting of 30 degrees ≤ a ≤ 60 degrees facilitates the operation member 4 in pushing the retaining member 3 to deform the elastic member 2, and also facilitates the elastic force of the elastic member 2 in causing the retaining member 3 to push the operation member 4 back to its original position. For example, if the angle is too large, the elastic member 2 needs a large elastic force to make the operation member 4 back to its original position; if the angle is too small, the operation member 4 needs a larger force to make the retaining member 3 move and deform the elastic member 2.

[0072] See Figure 8 , Figure 1 and Figure 4 The cup lid assembly 10 includes a shielding cover 5. The shielding cover 5 and the lid body 1 form a receiving cavity. The retaining member 3, the elastic member 2, and the operating member 4 are located within the receiving cavity. The shielding cover 5 includes a shielding cover through hole 51. The through direction of the shielding cover through hole 51 is the same as the through direction of the connecting hole 11. The operating member 4 is clearance-fitted with the shielding cover through hole 51 and extends out of the cup lid assembly 10 from the shielding cover through hole 51.

[0073] As described above, since the through-hole 51 of the cover has the same through-hole direction as the connecting hole 11, and the operating member 4 is clearance-fitted with the through-hole 51 of the cover and extends out of the cup lid assembly 10 from the through-hole 51 of the cover, the main unit does not need to have a structure for abutting the operating member 4. Instead, the operating member 4 can be operated by directly abutting a part of the main unit against the operating member 4, thus simplifying the structure of the main unit.

[0074] See Figures 8 to 10 , Figure 14 and Figure 15 The cover 1 is provided with three guide posts 12, and the lines connecting the beginning and end of the three guide posts 12 form a triangle. The operating component 4 is provided with mounting holes 43. See also Figure 14 and Figure 15 The mounting holes 43 are inserted one-to-one with the guide posts 12. In some embodiments, the operating member 4 is provided with three guide posts, and the lines connecting the ends of the three guide posts 12 form a triangle. The cover is provided with mounting holes 43.

[0075] As described above, since the lines connecting the beginning and end of the three guide posts 12 form a triangle, the mounting holes 43 are inserted into the guide posts 12 one by one, thus guiding the movement of the operating member 4. This facilitates the precise cooperation between the operating member 4 and the retaining member 3, thereby better enabling the fixing part 31 to fix or release the stirring member 20.

[0076] See Figure 8 , Figure 9 , Figure 16 , Figure 17 , Figure 20 and Figure 21 The rotating shaft structure 310 includes a rotating shaft hole 3101 disposed in the retaining member 3, and a rotating shaft 3102 disposed in the cover body 1. The rotating shaft 3102 is located within the rotating shaft hole 3101, and the inserted state is described in detail below. Figure 9 and Figure 10 In other embodiments, a pivot hole 3101 is provided in the cover 1, and a pivot 3102 is provided in the retainer 3. Regardless of the embodiment, the axis of the pivot 3102 is parallel to the axis of the connecting hole 11.

[0077] As described above, the rotating shaft 3102 is located inside the rotating shaft hole 3101, and the hole and shaft are matched to ensure that the rotation of the component 3 is smooth and more stable.

[0078] See Figure 8 and Figure 9 , Figures 11 to 13 The cover 1 includes a column 17. The connecting hole 11 also passes through the column 17. The column 17 includes a side wall opening 171 communicating with the connecting hole 11. The side wall opening 171 is located on the path of the fixing part 31 when switching between the open and closed states, that is, see... Figures 9 to 11 When the fixing part 31 is in the retracted state and the stirring member 20 is fixed, the fixing part 31 passes through the side wall opening 171 and is located within the connecting hole 11. See also Figure 12 and Figure 13 When the fixing part 31 is in the open state and the stirring member 20 is released, the fixing part 31 is located inside the side wall opening 171.

[0079] As described above, when the fixing part 31 is retracted and the stirring member 20 is fixed, the fixing part 31 passes through the side wall opening 171 and is located inside the connecting hole 11. When the fixing part 31 is opened and the stirring member 20 is released, the fixing part 31 is located inside the side wall opening 171. In this way, the side wall opening 171 can guide the movement of the retaining member 3, which is more conducive to the fixing part 31 fixing the stirring member 20 or releasing the stirring member 20. At the same time, the side wall of the side wall opening 171 can limit the retaining member 3 downward in the axial direction of the column 17, which is conducive to ensuring that the fixing part 31 can better release or fix the stirring member 20. In addition, 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, and thus, is more conducive to the fixing part 31 fixing or releasing the stirring member 20.

[0080] See Figure 1 , Figure 2 , Figures 4 to 7 This 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 is not limited to this. After connection, when it is necessary to release the blending element 20, the fixing part 31 of the retaining member 3 releases the blending element 20 by operating (e.g., pressing) the operating member. For example, after the drive shaft 20030 is connected to the mixing element 20 and the mixing element 20 is released by the fixing part 31, the drive shaft 20030 can drive the mixing element 20 to rotate inside the mixing cup 30 to process the food.

[0081] As described above, the food processor includes at least the beneficial effects of the lid assembly 10.

[0082] See Figures 1 to 7The main unit 200 includes a main unit housing 2002, a drive assembly 2003, and a lifting assembly 2004. In this embodiment, 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.

[0083] 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.

[0084] See Figure 2 and Figures 4 to 7The 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 abutment portion 20020. When the support platform 2001 is raised to its highest position, the abutment portion 20020 abuts against the operating member 4, causing the fixing portion 31 of the retaining member 3 to open and release 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 abutment portion 20020 and the operating member 4 cooperate through an inclined surface to realize the movement of the retaining member 3 and the operating member 4 until the stirring member 20 is released. Of course, during the descent of the support platform 2001, the cooperation relationship between the operating member 4, the retaining member 3, and the elastic member 2 is described in the above description of 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 element 20, the abutment portion 20020 remains in contact with the operating element 4 as the support platform 2001 continues to rise, allowing the operating element 4 to move until the stirring element 20 is released. Regardless of the method, the abutment portion 20020 abuts against the operating element 4 only after the drive shaft 20030 connects to the stirring element 20. During the descent of the support platform 2001, the force applied to the operating element 4 by the abutment portion 20020 is less than the elastic force applied to the operating element 4 by the elastic element 2. Therefore, as the support platform 2001 descends, the elastic force of the elastic element 2 eventually causes the fixing portions 31 to close together. Of course, for... Figure 8 The first type of cup lid assembly 10 shown has an operating member 4 extending out of the cover 5. Thus, the abutment part 20020 can be a flat part on the main housing 2002. It can also be understood that in this case, the main housing 2002 does not need to be specially provided with a part for abutting the operating member 4.

[0085] As described above, when the support platform 2001 rises, the abutment part 20020 abuts against the operating member 4, driving the retaining member 3 to rotate around the rotating shaft structure 310, causing the fixing part 31 to open until the stirring member 20 is released. Thus, the stirring member 20 is automatically released, making the operation simpler.

[0086] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
