The stirring assembly 100 of the food processor 1000 according to the embodiment of the present invention is described below with reference to fig. 1 to 7.

Referring to fig. 1 to 7, a stirring assembly 100 according to an embodiment of the present invention includes a stirring member 10 and a driving shaft 20.

Wherein, stirring member 10 is equipped with jack 11, and the pore wall of jack 11 is equipped with first groove section 111 and second groove section 112, and first groove section 111 and second groove section 112 communicate each other. The first groove section 111 extends along the axial direction of the stirring part 10 to form a notch 113 on the end face of the stirring part 10, the second groove section 112 extends along the circumferential direction of the stirring part 10, and the second groove section 11 is positioned on the side of the first groove section 111 far away from the notch 113. The second trough section 112 has a dimension larger than that of the end portion of the first trough section 111 close to the second trough section 112 (the upper end of the first trough section 111 shown in fig. 7) in the circumferential direction of the stirring member 10. The outer circumferential surface of the drive shaft 20 is provided with an insertion projection 21, and the drive shaft 20 can be inserted into the insertion hole 11 so that the insertion projection 21 can be mounted to the second groove section 112 through the first groove section 111.

Specifically, since the insertion convex portion 21 is disposed on the driving shaft 20, and the insertion convex portion 21 is mounted on the second groove section 112, during the rotation of the driving shaft 20, the insertion convex portion 21 can be matched with the wall surface of the second groove section 112, for example, the insertion convex portion 21 abuts against the end surface of one end of the second groove section 112 along the circumferential direction of the stirring part 10, or the insertion convex portion 21 is under the friction force of the wall surface of the second groove section 112, so that the driving shaft 20 can drive the stirring part 10 to rotate.

In addition, during the stirring process, the stirring part 10 is easily lifted by the food stacked at the bottom of the food processor 1000 to move upwards. And because the size of the second groove section 112 along the circumferential direction of the stirring part 10 is larger than the size of the end part, close to the second groove section 112, of the first groove section 111 along the circumferential direction of the stirring part 10, the part, exceeding the first groove section 111, of the second groove section 112 has wall surfaces positioned on the upper side and the lower side of the insertion convex part 21, and the two wall surfaces are matched with the insertion convex part 21 to limit the second groove section 112 in the up-and-down direction, so that the stirring part 10 is prevented from being jacked up by food and falling off from the driving shaft 20.

In addition, the present application can connect the stirring element 10 and the drive shaft 20 by mounting the plug-in protrusion 21 on the second groove section 112. When the stirring element 10 is to be removed, the removal can be carried out by simply aligning the plug-in projection 21 with the first trough section 111 and then lifting the stirring element 10 upwards. When the stirring part 10 is installed, the assembly can be completed only by aligning the insertion convex part 21 with the first groove section 111 and then inserting the driving shaft 20 into the stirring part 10, thereby realizing simple up-and-down assembly and disassembly.

According to the stirring assembly 100 of the food processor 1000 of the embodiment of the present invention, the insertion convex portion 21 is disposed on the driving shaft 20, and the insertion convex portion 21 is installed on the second groove section 112, so that when the driving shaft 20 rotates, the insertion convex portion 21 can be matched with the wall surface of the second groove section 112, thereby driving the stirring member 10 to rotate; moreover, the stirring device 10 is prevented from being lifted by the accumulated food materials and falling off the driving shaft 20; in addition, the stirring piece 10 is very simple and quick to disassemble and assemble, and the assembling and disassembling efficiency can be greatly improved.

According to some embodiments of the present invention, as shown in fig. 2-4 and 7, the maximum dimension of the insertion convex portion 21 is D1 and the minimum dimension of the first groove section 111 is L1, -0.3mm ≦ L1-D1 ≦ 0.2mm in the circumferential direction of the stirring member 10, so that the insertion convex portion 21 can smoothly pass through the first groove section 111 during the process of installing or removing the stirring member 10.

Specifically, when L1-D1 is more than 0 and less than or equal to 0.2mm, the inserting convex part 21 is in clearance fit with the first groove section 111 when passing through the first groove section 11; when L1-D1=0, the insertion projection 21 is in transition fit with the first groove section 111, and in both cases, the insertion projection 21 can pass through the first groove section 111 very easily because there is no interference between the insertion projection 21 and the first groove section 111.

When L1-D1 is less than or equal to 0.3mm, the inserting convex part 21 is in interference fit with the first groove section 111 when passing through the first groove section 11, and at the moment, the inserting convex part 21 and the first groove section 111 have interference, but the interference amount is small, and the inserting convex part 21 can also pass through the first groove section 111.

For the clearance fit and the transition fit, the stirring piece 10 is more labor-saving and convenient to assemble and disassemble on the driving shaft 20, and the use experience of a user is improved; when the inserting convex part 21 is in interference fit with the first groove section 111, the stirring piece 10 is more laboriously mounted and dismounted, but the effect of preventing the stirring piece 10 from falling off is better.

It should be noted that, here, the "minimum dimension L1 of the first groove section 111" may be equal to the dimension of the end of the first groove section 111 close to the second groove section 112 along the circumferential direction of the stirring member 10, and may also be smaller than the dimension of the end of the first groove section 111 close to the second groove section 112 along the circumferential direction of the stirring member 10, which is within the protection scope of the present invention.

The width of the first groove section 111 along the circumferential direction of the stirring member 10 may be equal everywhere or at least partially different, for example, as shown in fig. 7, the first groove section 111 includes an equal-width groove section and a flaring groove section, wherein the upper end of the equal-width groove section is communicated with the second groove section 112, the lower end of the equal-width groove section is communicated with the small end of the flaring groove section, and the large end of the flaring groove section is formed as a notch 113. Wherein, the groove width of the equal-width groove section is L1.

According to some embodiments of the present invention, as shown in fig. 2-4 and 7, in the axial direction of the stirring member 10, the maximum size of the inserting convex portion 21 is D2, the minimum size of the second groove section 112 is L2, -0.3mm is not less than L2-D2 is not less than 0.2mm, so that the inserting convex portion 21 can be installed in the second groove section 112 during the installation of the stirring member 10, and the transmission efficiency of the inserting convex portion 21 and the wall surface of the second groove section 112 is high during the stirring process, so as to drive the stirring member 10 to rotate.

Specifically, when L2-D2 is more than 0 and less than or equal to 0.2mm, the inserting convex part 21 is in clearance fit with the second groove section 112; when L2-D2=0, the plugging convex portion 21 and the second slot segment 112 are in transition fit. In both cases, the plug-in lug 21 can be mounted on the second groove section 112, since there is no interference of the plug-in lug 21 with the second groove section 112. In the stirring process, the inserting convex part 21 can be abutted against the end face of one end of the second groove section 112 along the circumferential direction of the stirring piece 10 under the torsion action of the driving shaft 20, so that the driving force and the driving stability of the stirring piece 10 are improved.

When the L2-D2 is less than or equal to 0.3mm, the inserting convex part 21 and the second groove section 112 are in interference fit. At this time, the insertion convex portion 21 interferes with the second groove section 112, but the interference amount is small, and the insertion convex portion 21 can be attached to the second groove section 112. In the stirring process, the friction force between the insertion convex part 21 and the wall surface of the second groove section 112 is large, so that the stirring part 10 is driven to rotate more efficiently, or the insertion convex part 21 can be abutted against the end surface of one circumferential end of the second groove section 112 under the action of the torque force of the driving shaft 20.

For the clearance fit and the transition fit, the stirring piece 10 is more labor-saving and convenient to assemble and disassemble on the driving shaft 20, and the use experience of a user is improved; when the inserting convex part 21 is in interference fit with the second groove section 111, the stirring part 10 is more laboriously mounted and dismounted, but the efficiency of driving the stirring part 10 to rotate by the driving shaft 20 is higher.

According to some embodiments of the present invention, as shown in fig. 2-4 and 7, in the circumferential direction of the stirring element 10, the maximum size of the insertion convex portion 21 is smaller than the minimum size of the first groove section 111, and the insertion convex portion 21 is in clearance fit with the first groove section 111, so that the insertion convex portion 21 can more easily pass through the first groove section 111 during the process of installing or detaching the stirring element 10.

According to some embodiments of the present invention, as shown in fig. 2-4 and 7, in the axial direction of the stirring part 10, the maximum dimension of the insertion convex portion 21 is smaller than the minimum dimension of the second groove section 112, and at this time, the insertion convex portion 21 and the second groove section 112 are in clearance fit, so that the insertion convex portion 21 can be more easily installed on the second groove section 112, and when the driving shaft 20 rotates, the insertion convex portion 21 can be more firmly contacted with the end surface of the second groove section 112 along the circumferential direction of the stirring part 10, so as to drive the stirring part 10 to stably rotate, and play a role of preventing the stirring part 10 from being pushed up by food.

According to some embodiments of the present invention, as shown in fig. 3 to 7, the first groove section 111 may communicate with the middle of the second groove section 112, so that the insertion convex portion 21 can be mounted to the second groove section 112 through the first groove section 111 when the driving shaft 20 is inserted into the insertion hole 11. Moreover, the first groove section 111 and the second groove section 112 are communicated with each other at the middle part, so that the first groove section 111 and the second groove section 112 are integrally formed into a T-shaped groove, and on one hand, the T-shaped groove is beneficial to ensuring that the whole structure of the jack 11 is more stable; on the other hand, the T-shaped groove can enable the insertion convex portion 21 to abut against the end surface of the second groove section 112 along the circumferential direction of the stirring part 10 when the driving shaft 20 rotates clockwise or counterclockwise, so as to drive the stirring part 10 to rotate clockwise or counterclockwise, and enable the stirring part 10 to be limited in the up-and-down direction, so that the stirring part 10 is prevented from being jacked up by food.

According to other embodiments of the present invention, as shown in fig. 3-7, the first groove section 111 may communicate with the end of the second groove section 112, in other words, the first groove section 111 may communicate with the end of the second groove section 112 along one circumferential end of the stirring member 10, the first groove section 111 may also communicate with the end of the second groove section 112 along the other circumferential end of the stirring member 10, and in both cases, the first groove section 111 and the second groove section 112 can both form an L-shaped groove to improve the structural strength of the insertion hole 11.

It should be noted that, when the first groove section 111 and the second groove section 112 are communicated to form an L-shaped groove, the insertion protrusion 21 can only rotate to the portion of the second groove section 112 staggered from the first groove section 111 in one of the clockwise rotation and the counterclockwise rotation of the driving shaft 20, so as to limit the stirring element 10 in the up-down direction.

According to some embodiments of the utility model, as shown in fig. 1 and fig. 2, the terminal surface and the grafting convex part 21 face-to-face contact of second groove section 112 along stirring 10 circumference one end to when guaranteeing that actuating system 200 drives drive shaft 20 rotatory, drive shaft 20 can drive stirring 10 rotatory, and transmission efficiency is high, and structural reliability is stronger.

According to other embodiments of the present invention, as shown in fig. 3-5, the first groove section 111 and the second groove section 112 radially penetrate through the hole wall of the insertion hole 11 along the insertion hole 11, on one hand, the stirring member 10 can be cleaned more conveniently without a cleaning dead angle, so as to avoid affecting food sanitation due to the fact that the stirring member is not cleaned in place; on the other hand, the penetrating structure makes it easier for a user to check the matching condition of the insertion convex part 21 with the first slot section 111 and the second slot section 112, so as to check whether the insertion convex part 21 is installed in place in the second slot section 112, and make the assembly and disassembly more convenient.

In addition, the processing technology of the first groove section 111 and the second groove section 112 can be simpler, which is beneficial to improving the production efficiency and reducing the production cost. For example, in machining the second channel section 112, it is only necessary to perform a simple punching operation on the stirring element 10. And also facilitates adjusting the position of insertion of the connecting rod 23 into the mounting hole 221 in some embodiments in which the drive shaft 20 includes the connecting rod 23.

In some embodiments, as shown in fig. 2 to 4, the insertion protrusion 21 may be integrally formed on the driving shaft 20, and in this case, the driving shaft 20 is a single piece and may be integrally cast without subsequent connection, which is beneficial to simplifying the processing procedure, improving the production efficiency, and providing higher structural strength.

Of course, the drive shaft 20 may also be a separate piece. For example, in some embodiments, as shown in fig. 2-4, the drive shaft 20 may include: a shaft body 22 and a connecting rod 23. Wherein, the shaft body 22 is provided with a mounting hole 221 extending along the radial direction; the connecting rod 23 is inserted into the mounting hole 221, and a portion of the connecting rod 23 is located outside the mounting hole 221 to form the insertion convex portion 21.

In addition, drive shaft 20 is connected with the actuating system 200 transmission of cooking machine 1000, and when actuating system 200 drove axle body 22 and rotated, because connecting rod 23 inserted and locates mounting hole 221, consequently axle body 22 can drive connecting rod 23 rotatory to make the wall cooperation of grafting convex part 21 and second groove section 112, and then drive stirring piece 10 rotatory, and grafting convex part 21 can carry on spacingly to stirring piece 10 from top to bottom, in order to prevent that stirring piece 10 is eaten material jack-up.

In some embodiments, as shown in fig. 1 and 2, the connecting rod 23 may be flush with or spaced apart from the hole wall of the mounting hole 221 by a predetermined gap. That is to say, when the connecting rod 23 is fitted to the hole wall of the mounting hole 221, the fitting manner between the connecting rod 23 and the mounting hole 221 may be interference fit or transition fit; when the connecting rod 23 is spaced apart from the hole wall of the mounting hole 221 by a predetermined gap, the connecting rod 23 is fitted to the mounting hole 221 in a gap fit manner.

Specifically, when the connecting rod 23 is in interference fit or transition fit with the mounting hole 221, on one hand, food can be prevented from entering the mounting hole 221; on the other hand, in the stirring process, the force transmission between the connecting rod 23 and the hole wall of the mounting hole 221 can be more uniform, and the stress concentration at the axial end of the mounting hole 221 is avoided, so that the service life of the driving shaft 20 is prolonged. In addition, when the connecting rod 23 is in interference fit with the mounting hole 221, the connecting rod 23 can be effectively prevented from axially moving along the mounting hole 221, so that when the connecting rod 23 is mounted to the second groove section 112, the position of the connecting rod 23 inserted into the mounting hole 221 does not need to be adjusted.
