Description

TECHNICAL FIELD

[0001] The present application relates to small household appliances, in particular to a cup cover assembly and a food processor. BACKGROUND

[0002] The food processor comprises a main machine and a stirring cup assembly. The main machine comprises a driving mechanism and a driving shaft. The stirring cup assembly comprises a stirring cup, a cup cover assembly and a stirring piece. The cup cover assembly comprises a cover body and a fixing releasing structure. The stirring piece is fixed to the cup cover through the fixing releasing structure. The driving shaft extends into the stirring cup and is connected with the stirring piece. Then, the fixing releasing structure releases the stirring piece. After the release, the driving mechanism drives the driving shaft, and the driving shaft drives the stirring piece to rotate in the stirring cup to process food.

[0003] In the above food processor, how to release or fix the stirring piece through simple operation is a technical problem to be solved. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to disclose a cup cover assembly and a food processor. The cup cover assembly can release or fix the stirring piece through simple operation.

[0005] In the first aspect, the present application discloses a cup cover assembly. The cup cover assembly comprises a cover body, an elastic piece, two retaining pieces and an operating piece. The cover body comprises a connecting hole, which penetrates the cover body in the thickness direction of the cover body. The cup cover assembly comprises a mounting portion, and the elastic piece abuts against the operating piece and the mounting portion. Each retaining piece is connected with the cover body through a rotating shaft structure; each retaining piece comprises a fixing portion and a connecting portion located on both sides of the rotating shaft structure, and each connecting portion is connected with the operating piece. When the operating piece is not operated, two fixing portions are folded towards each other at the connecting hole under the action of the elastic piece, so as to clamp the stirring piece together; when the operating piece is operated to move towards the connecting hole along the radial direction of the cover body, the elastic piece is deformed, and the retaining pieces are rotated to make two fixing portions open to each other until the stirring piece is released.

[0006] As set forth above, when the operating member is not operated, the two fixing portions are folded towards each other at the connecting hole under the action of the elastic member, so as to clamp the stirring member together; when the operating member is operated to move along the radial direction of the cover towards the connecting hole, the elastic member is deformed, and the retaining member rotates to make the two fixing portions open towards each other until the stirring member is released, thereby releasing or fixing the stirring member through simple operation, and the operation is convenient. In addition, in the above structure, only the elastic member needs to be deformed by pressing the operating member, and during the operation of the operating member, no torque is generated to make the cover rotate relative to the stirring cup, and no fixing structure for preventing rotation needs to be arranged between the cover and the stirring cup. Finally, the cup cover assembly realizes the fixing or releasing of the stirring member through the cover, the elastic member, the retaining member and the operating member, and has the advantages of fewer components, simple structure, fewer assembly procedures and low cost.

[0007] In some embodiments, when the two connecting portions are folded towards each other, the two fixing portions are opened towards each other; when the two connecting portions are opened towards each other, the two fixing portions are folded towards each other to fix the stirring member; or, when the two connecting portions are folded towards each other, the two fixing portions are folded towards each other; and when the two connecting portions are opened towards each other, the two fixing portions are opened towards each other.

[0008] As set forth above, any of the above manners can make the two fixing portions move synchronously, and finally, the degree of folding or opening of the two fixing portions is well matched with the shape of the fixing structure of the stirring member, and the two fixing portions can more accurately fix or release the stirring member, for example, one fixing portion cannot accurately clamp the stirring member because the other fixing portion has not yet clamped the step, or the degree of opening of one fixing portion relative to the connecting hole can release one side of the stirring member, and the degree of opening of the other fixing portion relative to the connecting hole cannot release the other side of the stirring member.

[0009] In some embodiments, the rotating shaft structure comprises a rotating shaft hole arranged in one of the retaining member and the cover, and a rotating shaft arranged in the other one, and the rotating shaft is located in the rotating shaft hole.

[0010] As set forth above, by locating the rotating shaft in the rotating shaft hole, the hole-shaft cooperation is adopted, and the rotation of the retaining member is smooth and stable.

[0011] In some embodiments, the operating member comprises two sliding grooves, the width between the two sliding grooves gradually increases towards the connecting hole; each connecting portion comprises a guide column relative to the fixing portion; and during the switching between the opening and folding of the two fixing portions towards each other, the guide column moves in the sliding groove one by one.

[0012] As set forth above, due to the gradually increasing width between the two grooves towards the connecting hole, and the movement of the guide posts in the grooves in correspondence with the switching between the opening and closing of the fixing portions, the opening or closing degree of the fixing portions of the holders relative to the connecting hole is ensured to be consistent, and the stirring member is released or fixed more accurately.

[0013] In some embodiments, each groove comprises a first groove and a second groove connected in series, and the second groove forms an obtuse angle with the first groove. The two first grooves are parallel to each other, and the distance between the two second grooves increases towards the connecting hole.

[0014] As set forth above, each groove comprises a first groove and a second groove, so that the structure of the operating member is simple. By making the second groove form an obtuse angle with the first groove and the first grooves parallel to each other, the opening degree of the fixing portions is avoided to be too large, so that when the fixing portions need to be closed to fix the stirring member, the fixing portions cannot fix the stirring member, such as the fixing portions cannot clamp the first section and fall out of the step, because the fixing portions may be clamped in the second section. In addition, the first grooves are parallel to each other, and the space between the first grooves can also be used to accommodate the elastic member, so that the structure of the operating member is also simple.

[0015] In some embodiments, the two grooves are symmetrically arranged. In the case of one elastic member, the elastic member is located on the symmetry axis of the two grooves, or the elastic member is parallel to the symmetry axis and the distance between the elastic member and the symmetry axis is less than or equal to 10 mm. In the case of multiple elastic members, the elastic members are symmetric relative to the symmetry axis.

[0016] As set forth above, by symmetrically arranging the grooves and the elastic member satisfying the above relationship with the symmetry axis, the operating member is balanced in force, and the two holders are balanced in force, so that the stirring member can be better fixed or released.

[0017] In some embodiments, the cup cover assembly comprises a notch, and the operating member is in clearance fit with the notch side wall during movement.

[0018] As set forth above, during the movement of the operating member, the operating member is in clearance fit with the notch side wall, so that the notch can guide the movement of the operating member, and the operating member can move linearly towards the connecting hole.

[0019] In some embodiments, the cover includes a column, the connecting hole further penetrates the column; the column includes a side wall opening communicating with the connecting hole; in the case that the fixing part is in the collapsed state to fix the stirring piece, the fixing part penetrates the side wall opening and is located in the connecting hole; in the case that the fixing part is in the expanded state to release the stirring piece, the fixing part is located in the side wall opening.

[0020] As described above, in the case that the fixing part is in the collapsed state to fix the stirring piece, the fixing part penetrates the side wall opening and is located in the connecting hole, and in the case that the fixing part is in the expanded state to release the stirring piece, the fixing part is located in the side wall opening, so that the movement of the retaining piece can be guided by the side wall opening, which is more conducive to fixing or releasing the stirring piece by the fixing part. Meanwhile, the side wall of the side wall opening can limit the downward movement of the retaining piece in the axial direction of the column, which is conducive to ensuring that the fixing part better releases or fixes the stirring piece. In addition, the connecting hole further penetrates the column, which is conducive to the stirring piece being coaxial with the connecting hole, and further conducive to the fixing part fixing or releasing the stirring piece.

[0021] The application further discloses a food processor. The food processor includes a main machine and a stirring cup assembly; the stirring cup assembly includes any one of the cup cover assemblies, a stirring piece and a stirring cup, the main machine includes a driving shaft; the driving shaft is connected with the stirring piece through the connecting hole.

[0022] As described above, the food processor at least has the beneficial effects of the cup cover assembly.

[0023] In some embodiments, the main machine includes a main machine housing, a driving assembly and a lifting assembly, the driving assembly includes the driving shaft, the lifting assembly is connected with the driving assembly to drive the driving assembly to lift in the main machine housing; in the case that the stirring piece is released, the driving shaft drives the stirring piece to lift in the stirring cup.

[0024] As described above, the driving assembly is lifted as a whole to drive the stirring piece to lift, which avoids loosening of the driving shaft and other components due to lifting, noise and the like, ensures smoother movement of the driving shaft, and smaller noise of the food processor, compared with lifting only the driving shaft to drive the stirring piece to lift.

[0025] In some embodiments, the main machine includes a liftable bearing table, the stirring cup assembly is located on the bearing table, and the main machine housing includes an abutting part; in the case that the bearing table is lifted to the highest position, the abutting part abuts against the operating piece to make the fixing part of the retaining piece release the stirring piece.

[0026] As set forth above, the lifting of the bearing table makes the abutting part abut against the operating part to drive the operating part to move along the radial direction of the cover body, so that the holding part rotates around the rotating shaft structure, the fixed part is opened until the stirring part is released, thereby automatically releasing the stirring part, and the operation is simpler.

[0044] The technical solutions in the embodiments (or, the implementation manners) of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0045] If the embodiments of the present application involve directional indications or positional relationships (such as up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such directional indications or positional relationships are only used to explain the relative positional relationships, movement conditions, etc. between the components in a certain posture (as shown in the drawings); if the certain posture changes, the directional indications or positional relationships also change accordingly. In addition, the terms “first”, “second”, etc. in the embodiments of the present application are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0046] Referring to Figure 8 , Figure 9 , Figure 11 , Figure 13 to Figure 16 , the present application discloses a cup lid assembly 10. The cup lid assembly 10 comprises a lid 1, an elastic member 2, two holders 3 and an operating member 4. In some embodiments, the cup lid assembly 10 further comprises a cover 5. The cover 5 and the lid 1 constitute a containing space. The elastic member 2 and the holders 3 are located in the containing space, and the operating member 4 is located in the containing space and extends out of the containing space, so as to extend out of the cup lid assembly 10.

[0047] Referring to Figure 8 , Figure 9 , Figure 11 and Figure 13 , the cover 1 includes a connecting hole 11 which penetrates the cover 1 in the thickness direction of the cover 1. One function of the connecting hole 11 is to connect the stirring member 20 with the driving shaft so that the stirring member 20 can be finally fixed or released by the holding member 3, therefore, the structure of the connecting hole 11 is not limited as long as the function can be achieved.

[0048] Referring to Figure 8 , Figure 9 , Figure 11 , Figure 13 and Figure 14 , the cup cover assembly 10 includes a mounting portion 14. The elastic member 2 is located between the operating member 4 and the mounting portion 14, so that the mounting portion 14 serves as the force point of the elastic member 2, therefore, the mounting portion 14 can be arranged on the cover 1, or on the shielding cover 5, or on other components of the cup cover assembly 10, as long as the function of the aforementioned force point can be achieved. The structure of the elastic member 2 is not limited, and how to abut against the mounting portion 14 is not limited, as long as the reset of the operating member 4 can be achieved. The elastic member 2 in Figure 8 to Figure 10 is a compression spring, and can also be a tensile spring. Of course, the number of the elastic member 2 is not limited to one as shown in the figure.

[0049] Referring to Figure 9 , Figure 10 , Figure 11 , Figure 13 and Figure 14 , each of the holding members 3 is connected with the cover 1 through a rotating shaft structure 310, for example, the rotating center line of the rotating shaft structure 310 is parallel to the center line of the connecting hole 11. The specific structure of the rotating shaft structure 310 is not limited, as long as the aforementioned function can be achieved. The state of the two holding members 3 connected with the cover 1 through the rotating shaft structure 310 is not limited, the first case is shown in Figure 13 to Figure 16 , each of the holding members 3 is assembled with the cover 1 through one of the rotating shaft structures 310, and the two holding members 3 are separated; the second case is shown in Figure 17 , the two holding members 3 are connected in a cross shape through one rotating shaft structure 310. No matter which case, each of the holding members 3 includes a fixed portion 31 and a connecting portion 32 located on both sides of the rotating shaft structure 310, and each of the connecting portions 32 connects the operating member 4.

[0050] Referring to Figure 9 to Figure 16The process of fixing and releasing the stirring member 20 is described as follows: before describing the process, the structure of the stirring member 20 is introduced. The stirring member 20 comprises a fixing structure. More specifically, the fixing structure of the stirring member 20 comprises a first section 201 and a second section 202, and the first section 201 and the second section 202 form a step. It is understood by the skilled in the art that the fixing structure is not limited to the step.

[0051] Fixing the stirring member 20: referring to Figure 16 , Figure 14 , Figure 11 , Figure 12 and Figure 13 , the operating member 4 is pressed in the direction of arrow f in Figure 9 , Figure 11 , Figure 13 , Figure 14 and Figure 16 , the fixing portions 31 are opened to each other in the direction of arrow r. The stirring member 20 is inserted into the connecting hole 11. Referring to Figure 9 to Figure 16 , the operating member 4 is released (i.e. the operating member 4 is not operated), and the external force on the operating member 4 is 0 at this time. The force on the operating member 4 is smaller than the elastic force of the elastic member 2. Of course, if there is an abutting portion abutting against the operating member, the force between the abutting portion and the operating member is smaller than the elastic force of the elastic member 2. In this way, under the action of the elastic force of the elastic member 2, the operating member 4 moves in the direction of arrow F (i.e. the outside of the cup cover assembly), that is, under the action of the elastic member 2, the two fixing portions 31 move in the direction of arrow R in Figure 9 , Figure 10 , Figure 13 to Figure 15 , and are closed to each other at the connecting hole 11 to jointly clamp the stirring member 20. When the stirring member 20 is clamped, the step formed by the first section 201 and the second section 202 is supported by the fixing portions 31, and the first section 201 is clamped by the two fixing portions 31. The state of the fixed stirring member 20 can be seen from Figure 9 , Figure 10 and Figure 14 . At this time, the state of the fixing portions 31 can be seen from Figure 13 . The unoperated state includes one of the following situations: 1) the situation of pressing the operating member 4 to release (at this time, the operating member 4 is only subjected to the elastic force of the elastic member 2 and is not operated); 2) the situation of not pressing the operating member 4; and 3) the situation of gradually releasing the abutting between the abutting portion of the main machine and the operating member due to the descent of the bearing table 2001 of the cup cover assembly 10, and the elastic member 2 gradually resets the operating member 4.

[0052] Release the stirring member 20: in the case that the operating member 4 is operated to move along the radial direction of the cover body 1 towards the connecting hole 11 (see the direction of arrow f in the figure), the elastic member 2 is deformed, the retaining member 3 is rotated to make the two fixing portions 31 open to each other (the opening direction is shown by arrow r in Figure 9 、 Figure 11 、 Figure 13 、 Figure 14 and Figure 16 , the stirring member 20 can be released. The state in which the stirring member 20 can be released is shown in Figure 11 and Figure 12 . The distance by which the fixing portions 31 are opened is greater than the diameter of the fixing structure, so that the step of the stirring member 20 is no longer supported by the fixing portions 31 and is released. After being released, in the case that the stirring member 20 is connected to the driving shaft 20030, the stirring member 20 can be rotated (only rotated, or both rotated and moved along the axis of the stirring cup 30) under the driving of the driving shaft 20030. In the present embodiment, in the case that the stirring member 20 is not connected to the driving shaft 20030, the stirring member 20 will fall after being released. It can be understood by the skilled in the art that the above-mentioned elastic member 2 is a compression spring, but the elastic member 2 can also be a tensile spring. In this case, the position of the mounting portion 14 needs to be changed from the present position shown in Figure 14 to the opposite position, that is, in the case that the elastic member 2 is a compression spring, the pressing of the operating member 4 makes the operating member 4 move along the direction of arrow f to release the stirring member 20, and the deformation of the elastic member 2 is compression. In the case that the elastic member 2 is a tensile spring, the movement of the operating member 4 along the direction of arrow f to release the stirring member 20 makes the elastic member 2 be elongated.

[0053] As set forth above, in the case that the operating member 4 is not operated, the two fixing portions 31 are folded to each other at the connecting hole 11 under the action of the elastic member 2 to be able to clamp the stirring member 20 together. In the case that the operating member 4 is operated to move along the radial direction of the cover body 1 towards the connecting hole 11, the elastic member 2 is deformed, and the retaining member 3 is rotated to make the two fixing portions 31 open to each other until the stirring member 20 can be released. Thus, the stirring member 20 can be released or fixed by simple operation, and the operation is convenient. In addition, in the above-mentioned structure, only the pressing of the operating member 4 is needed to release the stirring member 20, and no torque will make the cover body 1 rotate relative to the stirring cup 30 in the process of operating the operating member 4, so that no fixing structure for preventing rotation needs to be arranged between the cover body 1 and the stirring cup 30. Finally, the cup cover assembly realizes the fixing or releasing of the stirring member 20 through the cover body 1, the elastic member 2, the retaining member 3 and the operating member 4, so that the number of parts is small, the structure is simple, the assembly process is less and the cost is low.

[0054] See Figure 15 and Figure 16, in the case of two said connecting portions 32 mutually closing, two said fixing portions 31 mutually opening, namely, in Figure 16 , when the operating member 4 moves along the arrow f direction, the elastic member 2 deforms along the arrow f direction, each holding member 3 rotates around the respective pivot structure 310, thus, the connecting portions 32 mutually close along the arrow n direction, the fixing portions 31 mutually open along the arrow r direction; in the case of two said connecting portions 32 mutually opening, two said fixing portions 31 mutually closing to fix the stirring member; namely, in Figure 15 , when the operating member 4 moves along the arrow F direction, the elastic member 2 recovers from the deformed state, thus, each holding member 3 rotates around the respective pivot structure 310, thus, the connecting portions 32 mutually open along the arrow m direction, the fixing portions 31 mutually close along the arrow R direction.

[0055] Referring to Figure 17 , the working principle can be understood by means of a pair of pliers, in the case of two said connecting portions 32 mutually closing, two said fixing portions 31 mutually closing; in the case of two said connecting portions 32 mutually opening, two said fixing portions 31 mutually opening. Specifically, the directions of the connecting portions 32 mutually opening and the fixing portions 31 mutually opening are shown by the arrows M and m, the directions of the connecting portions 32 mutually closing and the fixing portions 31 mutually closing are shown by the arrows n and N. At this time, the cooperation between the elastic member 2 and the operating member 4 can also refer to the aforementioned cooperation, which will not be described again, of course, it is not limited to this way.

[0056] As described above, any of the aforementioned ways can make the two said fixing portions 31 move synchronously, finally, the degree of closing or opening of the two fixing portions 31 well matches the shape of the fixing structure of the stirring member 20, the two fixing portions 31 can more accurately fix or release the stirring member 20, for example, it is not easy to appear that one fixing portion 31 supports the said step, while the other fixing portion 31 has not supported the step, so that the two fixing portions 31 cannot accurately clamp the stirring member 20, or, the degree of opening of one fixing portion 31 relative to the connecting hole 11 can make the stirring member 20 on this side be released, the degree of opening of the other fixing portion 31 relative to the connecting hole 11 makes the stirring member 20 on the other side still cannot be released.

[0057] Referring to Figure 8 to Figure 10 and Figure 15 and Figure 16 , the pivot structure 310 includes a pivot hole 3101 arranged on the holding member 3, and a pivot 3102 arranged on the cover 1, the pivot 3102 is located in the pivot hole 3101. In other embodiments, the pivot hole 3101 is arranged on the cover 1, and the pivot 3102 is arranged on the holding member 3. Regardless of the way, the axis of the pivot 3102 is parallel to the axis of the connecting hole 11.

[0058] As set forth above, the rotation of the holder 3 is smooth and stable by the hole shaft cooperation of the rotation shaft 3102 in the rotation shaft hole 3101.

[0059] Referring to Figure 13 to Figure 16 , the operation member 4 comprises two sliding grooves 41, and the width between the two sliding grooves 41 gradually increases towards the connecting hole 11. This increase can be from one end of the sliding groove 41 to the other end, or as shown in Figure 13 to Figure 16 , a section of the sliding groove 41 gradually increases. Each of the connecting portions 32 comprises a guide column 321 relative to the fixed portion 31. The guide column 321 moves in the sliding groove 41 one by one during the switching process of the mutual opening and closing of the fixed portion 31.

[0060] As set forth above, since the width between the two sliding grooves 41 gradually increases towards the connecting hole 11, and the guide column 321 moves in the sliding groove 41 one by one during the switching process of the mutual opening and closing of the fixed portion 31, it is beneficial to ensure that the opening degree or closing degree of the fixed portion 31 of the holder 3 relative to the connecting hole 11 is consistent, and further, the stirring member 20 is released or fixed more accurately.

[0061] Referring to Figure 13 to Figure 16 , each of the sliding grooves 41 comprises a first sliding groove 411 and a second sliding groove 412 connected in communication. The second sliding groove 412 is at an obtuse angle with the first sliding groove 411. The two first sliding grooves 411 are parallel to each other. The distance between the two second sliding grooves 412 increases towards the connecting hole 11.

[0062] As set forth above, each sliding groove 41 comprises a first sliding groove 411 and a second sliding groove 412, so that the structure of the operation member 4 is simple. By the second sliding groove 412 being at an obtuse angle with the first sliding groove 411 and the first sliding grooves 411 being parallel to each other, it can be known from the position relationship between the fixed portion 31 and the step in Figure 12 and Figure 10 that the opening degree of the fixed portion 31 is not too large, so that when the fixed portion 31 needs to be closed to fix the stirring member 20, the fixed portion 31 cannot fix the fixed structure of the stirring member 20, such as the fixed portion 31 cannot hold the first section 201 and fall out of the step, because the fixed portion 31 can be clamped in the second section 202. In addition, the first sliding grooves 411 are parallel to each other, and the space between the first sliding grooves 411 can also be used to accommodate the elastic member 2, so that the structure of the operation member 4 is also simple.

[0063] Referring to Figure 13 to Figure 16 , the two sliding grooves 41 are symmetrically arranged, Figure 16The symmetry axis is L. In the case of one elastic member 2, the elastic member 2 is located on the symmetry axis L of the two sliding grooves 41, or the elastic member 2 is parallel to the symmetry axis L and the distance between the elastic member 2 and the symmetry axis L is less than or equal to 10 mm. In other embodiments, in the case of multiple elastic members 2, the elastic members 2 are symmetrical relative to the symmetry axis.

[0064] As described above, by symmetrically arranging the sliding grooves 41 and by the elastic member 2 satisfying the above relationship with the symmetry axis L, the operating member 4 is balanced, and in turn, the two retaining members 3 are balanced, which can better fix or release the stirring member 20.

[0065] Referring to Figure 8 , Figure 9 , Figure 11 , Figure 13 and Figure 14 , the cup cover assembly includes a notch 16. The cover body 1 and the cover 5 are both provided with the notch 16, and in other embodiments, only one of them needs to have the notch 16. Of course, the notch 16 can also be arranged on other components of the cup cover assembly 10. Referring to Figure 13 and Figure 14 and comparing with Figure 8 , the operating member 4 is in clearance fit with the notch side wall 161 of the notch 16 during movement, so as to guide the movement of the operating member 4. In some embodiments, the operating member 4 further includes a blocking portion 43, which abuts against the notch side wall of the notch 16 when the stirring member 20 is fixed by the fixing portion 31, referring to Figure 13 , and the blocking portion 43 is away from the notch 16 when the stirring member 20 is released. By arranging the blocking portion 43 to block the operating member 4, the operating member 4 is prevented from being separated from the cover body 1 by the elastic force of the elastic member 2.

[0066] As described above, since the operating member 4 is in clearance fit with the notch side wall 161 of the notch 16 during movement, the notch 16 can guide the movement of the operating member 4, which facilitates the linear movement of the operating member 4 towards the connecting hole 11.

[0067] Referring to Figure 9 to Figure 14 , the cover body 1 includes a column 17, and the connecting hole 11 also penetrates the column 17. The column 17 includes a side wall opening 171 which communicates with the connecting hole 11. The side wall opening 171 is located on the path of the fixing portion 31 switching between the open state and the closed state, that is, referring to Figure 9 , Figure 10 and Figure 13In the case that the fixing part 31 is in the contracted state to fix the stirring part 20, the fixing part 31 passes through the side wall opening 171 and is located in the connecting hole 11. See Figure 11 and Figure 12 In the case that the fixing part 31 is in the expanded state to release the stirring part 20, the fixing part 31 is located in the side wall opening 171.

[0068] As set forth above, in the case that the fixing part 31 is contracted to fix the stirring part 20, the fixing part 31 passes through the side wall opening 171 and is located in the connecting hole 11, and in the case that the fixing part 31 is expanded to release the stirring part 20, the fixing part 31 is located in the side wall opening 171, so that the movement of the holding part 3 can be guided by the side wall opening 171, and the fixing part 31 is more conducive to fixing or releasing the stirring part 20. Meanwhile, the side wall of the side wall opening 171 can limit the downward movement of the holding part 3 in the axial direction of the column 17, which is conducive to ensuring that the fixing part 31 better releases or fixes the stirring part 20. In addition, the connecting hole 11 also penetrates the column 17, which is conducive to the stirring part 20 being coaxial with the connecting hole 11, and further conducive to the fixing part 31 fixing or releasing the stirring part 20.

[0069] See Figure 1 , Figure 2 , Figure 4 to Figure 7 The application discloses a food processor. The food processor comprises a main machine 200 and a stirring cup assembly 100. The stirring cup assembly 100 comprises any one of the cup cover assemblies 10, the stirring part 20 and the stirring cup 30. The stirring cup 30 comprises an outer cup 301 and an inner cup 302 located in the outer cup 301. The main machine comprises a driving shaft 20030. The driving shaft 20030 is connected with the stirring part 20 through the connecting hole 11. The connection through the connecting hole 11 means that the whole connection of the stirring part 20 and the driving shaft 20030 passes through the connecting hole, which can be that the driving shaft 20030 and the stirring part 20 both pass through the connecting hole 11, or one of them passes through the connecting hole 11 to make the connection, and is not limited to this. After the connection, when it is needed to release the stirring part 20, the fixing part 31 of the holding part 3 releases the stirring part 20 by operating (such as pressing) the operating part 4. For example, after the driving shaft 20030 is connected with the stirring part 20 and the stirring part 20 is released by the fixing part 31, the driving shaft 20030 can drive the stirring part 20 to rotate in the stirring cup 30 to process food materials.

[0070] As set forth above, the food processor at least has the beneficial effects of the cup cover assembly 10.

[0071] See Figure 1 to Figure 7The host 200 includes a host housing 2002, a driving assembly 2003 and a lifting assembly 2004. The driving assembly 2003 includes the driving shaft 20030, a driving motor 20031 and a gear box assembly 20032 in the embodiment. The input end of the gear box assembly 20032 is connected with the driving motor 20031. The output end of the gear box assembly 20032 is connected with the driving shaft 20030. The lifting assembly 2004 is connected with the driving assembly 2003. The lifting assembly 2004 includes a lifting motor 20041, a screw rod 20042 and a guide mechanism in the application. Thus, the lifting assembly 2004 drives the driving assembly 2003 (the driving shaft 20030, the driving motor 20031 and the gear box assembly 20032) to lift in the host housing 2002. When the stirring piece 20 is released, the driving shaft 20030 drives the stirring piece 20 to lift in the stirring cup 30. The principle that the lifting assembly 2004 drives the driving assembly 2003 to lift is the same as the working principle of the screw rod, which will not be described herein. Figure 2 , Figure 6 and Figure 7 The host housing 2002 includes a base housing 20021, a lower head housing 20022 and an upper head housing 20023. The upper head housing 20023, the lower head housing 20022 and the base housing 20021 enclose a cavity for accommodating the driving assembly 2003. It is shown in Figure 6 and Figure 7 , Figure 6 that the driving assembly 2003 has not been lowered, and the stirring piece 20 connected with the driving shaft 20030 is located at the top of the stirring cup 30. Figure 7 that the driving assembly 2003 has been lowered, and the stirring piece 20 connected with the driving shaft 20030 has been lowered to the bottom of the stirring cup 30.

[0072] As described above, the stirring piece 20 is lifted by the lifting of the whole driving assembly 2003, which avoids the loosening of the driving shaft 20030 and other components due to the lifting, the generation of noise and the like, ensures the smoother movement of the driving shaft 20030 and the smaller noise of the food processor, compared with the lifting of the stirring piece 20 by the lifting of only the driving shaft 20030.

[0073] Referring to 2 and Figure 4 to Figure 7The main machine 200 includes a liftable bearing table 2001. The stirring cup assembly 100 is located on the bearing table 2001. The main machine shell 2002 includes an abutting part 20020. In the case that the bearing table 2001 is lifted to the highest position, the abutting part 20020 abuts against the operating part 4 to make the fixing part 31 of the holding part 3 open to release the stirring part 20. The lifting mode of the bearing table 2001 includes the following two modes: 1) the bearing table 2001 does not rotate during the lifting process. After the driving shaft 20030 is connected with the stirring part 20, the abutting part 20020 and the operating part 4 realize the movement of the holding part 3 and the operating part 4 through the slope cooperation during the continuous lifting process of the bearing table 2001, until the stirring part 20 is released. Of course, during the descending process of the bearing table 2001, the cooperation relationship among the operating part 4, the holding part 3 and the elastic part 2 is described in the foregoing part of the process of releasing and fixing the stirring part 20; 2) the bearing table 2001 rotates during the lifting process. Referring to Figure 4 The abutting part 20020 is in an inclined state relative to the circumference of the cover 1, so that the distance between the abutting part 20020 and the driving shaft 20030 gradually decreases towards the direction close to the connecting hole 11. Thus, after the driving shaft 20030 is connected with the stirring part 20, the abutting part 20020 can always contact the operating part 4 during the continuous lifting process of the bearing table 2001, so as to make the operating part 4 move until the stirring part 20 is released. Regardless of the mode, the abutting part 20020 abuts against the operating part 4 after the driving shaft 20030 is connected with the stirring part 20. During the descending process of the bearing table 2001, the force applied by the abutting part 20020 to the operating part 4 is smaller than the elastic force applied by the elastic part 2 to the operating part 4. Thus, with the descending of the bearing table 2001, finally, the elastic force of the elastic part 2 makes the fixing part 31 close to each other.

[0074] As described above, the lifting of the bearing table 2001 makes the abutting part 20020 abut against the operating part 4 to drive the operating part to move along the radial direction of the cover 1, so as to make the holding part 3 rotate around the rotating shaft structure 310, and the fixing part 31 open until the stirring part 20 is released. Thus, the stirring part 20 is automatically released, and the operation is simpler.

The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
