Fig. 3, 4 and 5 disclose a first type of blender blade assembly 10, fig. 9 discloses a second type of blender blade assembly 10, fig. 10 discloses a third type of blender blade assembly 10 and fig. 11 discloses a fourth type of blender blade assembly 10. Each of the four agitator blade assemblies 10 includes a cutter shaft 1, an elastic member 2, and a first blade 3. The elastic piece 2 is connected with the cutter shaft 1 and the first blade 3, and in the rotation process of the cutter shaft 1, the elastic piece 2 deforms to drive the first blade 3 to swing sideways of the cutter shaft 1.

According to the arrangement, as the elastic piece 2 deforms to drive the first blade 3 to swing laterally of the cutter shaft 1 in the rotation process of the cutter shaft 1, rolling of food in the food container is increased through swinging of the first blade 3, the food in the food container is uniformly whipped through rolling, for example, the food adhered to or piled up on the wall is uniformly whipped and whipped together with the food in the food container, and finally, the whole whipping of the food is uniform, and under the condition that the food is vegetables, the first blade 3 is driven to swing through deformation of the elastic piece, the food is easier to roll, the purpose of cutting and distributing vegetables is achieved, the cutting effect is improved, and the whipping of the food is uniform.

The structure of the elastic member 2 is not limited to the various structures described in the present application, as long as the swinging of the first blade 3 can be achieved, based on the action of the elastic member 2. Depending on the structure of the elastic member 2, the swing may be up and down, left and right, or up and down and left and right.

Some structures of the elastic member 2 are described as follows.

Referring to fig. 11, the elastic member 2 is a metal sheet. One end of the foil is fixedly connected to the arbor 1 and the other end is fixedly connected to the first blade 3, a connection 31 being schematically shown in fig. 11. In other embodiments, the elastic member 2 may also be a metal ring, i.e. a metal sheet with a central portion passing through. Since the elastic member 2 is a metal sheet or a metal ring, the first blade 3 can also swing, and thus, the food material is uniformly stirred as a whole. Of course, the elastic member 2 is not limited to the above-described structure, and the first blade 3 may be oscillated.

Referring to fig. 5, 6 and 9 in combination with fig. 3, 4 and 8, the elastic member 2 is fixedly sleeved on the cutter shaft 1, and the elastic member 2 and the side surface of the cutter shaft 1 enclose a cavity 21. The cavity 21 is not limited in terms of how the elastic member 2 is formed, and for example, the elastic member is formed in a penetrating shape, and is fixed to the arbor by passing through the arbor 1 to form the cavity 21. In fig. 5 and 6, the arbor 1 comprises a first arbor 11 and a second arbor 12, and the elastic member 2 and the side surface of the second arbor 12 of the arbor 1 form the cavity 21. In fig. 9, the arbor 1 has only one segment, unlike fig. 5 and 6, which have two segments (a first arbor 11 and a second arbor 12), and thus the elastic member 2 and the side surface of the arbor 1 constitute the cavity 21. The width of the cavity 21 along the radial direction of the cutter shaft 1 is not limited, and can meet the elastic deformation of the elastic member 2, for example, the width w meets the following conditions: w is more than or equal to 2mm and less than or equal to 10mm.

As the elastic member 2 and the side surface of the arbor 1 form the cavity 21, the cavity 21 provides a deformation space for the elastic member 2, so that the first blade 3 can swing better, for example, up and down and left and right.

Referring to fig. 6 in combination with fig. 5, 9, 3, 4 and 10, the elastic member 2 includes an elastic member body 22 connected with the first blade 3 and a connecting portion 23. The elastic member body 22 is located at the lateral direction of the cutter shaft 1, and the top end and the bottom end of the elastic member body 22 are respectively connected with one connecting portion 23. The connection portion 23 is bent. Each connecting part 23 is fixedly connected with the cutter shaft 1 respectively, so that the connecting parts 23 are fixed with the cutter shaft 1.

As the elastic member 2 includes the elastic member body 22 and the connecting portion 23 connected with the first blade 3, the elastic member body 22 is located at the lateral direction of the cutter shaft 1, and the connecting portion 23 is in a bent shape, so that the elastic member 2 has good elasticity, and the first blade 3 can swing better.

Referring to fig. 6, in the illustrated embodiment, each of the connection portions 23 includes an abutment portion 24, and the side surface of the arbor 1 is recessed to form a step 112, and the abutment portion 24 abuts against the arbor 1, specifically, the abutment portion 24 abuts against and is fixed to the step 112 of the arbor 1.

As set forth above, in the case where the elastic member 2 is penetrated and fixed by the arbor 1, the abutting portion 24 abuts against the arbor 1, for example, abuts against the step 112, so that the elastic member 2 can be well fixed to the arbor 1, and further, the elastic member 2 does not move in the circumferential direction and the axial direction of the arbor 1, and finally, the first blade 3 is ensured to swing under the deformation of the elastic member 2.

Referring to fig. 6 in combination with fig. 5, 9, 3, 4 and 10, the thickness of the connecting portion 23 is smaller than the thickness of the elastic member body 22, for example, in fig. 6, the thickness of the connecting portion 23 is t1, and the thickness of the elastic member body 22 is t2, t1 < t2.

As the thickness of the connecting portion 23 is smaller than that of the elastic member body 22 and is bent, the elastic member 2 has better elasticity, and the first blade 3 can swing better.

Referring to fig. 6, the connecting portion 23 includes two arc-shaped walls 231, and the two arc-shaped walls 231 are tangent and connected to each other such that the connecting portion 23 is bent.

As the two arc walls 231 are tangent and connected to make the connecting portion 23 bend, the elasticity of the elastic member 2 is better, and the first blade 3 can swing better.

Referring to fig. 9, the stirring blade assembly 10 includes a second blade 4 fixed to the cutter shaft 1, wherein the second blade 4 has a height difference from the first blade 3 in the axial direction of the cutter shaft 1, and is staggered from the first blade 3 in the circumferential direction of the cutter shaft 1. That is, in this embodiment, the second blade 4 is a blade that cannot be swung, and the first blade 3 is a blade that can be swung. The height difference is for example in the embodiment shown in fig. 9 that the second blade 4 is located below the first blade 3, in other embodiments the height difference may be that the second blade 4 is located above the first blade 3. Only two first blades 3 are also shown in fig. 9 and have a height difference. Based on the aforementioned concept of combining the swingable first blades 3 with the non-swingable second blades 4, the number of the first blades 3 and the number of the second blades 4 are not limited.

By combining the non-swingable second blade 4 with the swingable first blade 3 as described above, one main function of the non-swingable second blade 4 is to cut the food, and of course, the second blade 4 has a stirring function or the like, and one main function of the swingable first blade 3 is to stir the food, and of course, the first blade 3 also has the cutting function or the like, so that the combination of the first blade 3 and the second blade 4 can make the food whipping more uniform.

Of course, in various embodiments of the present application, the stirring blade assembly 10 may include only the first blade 3 and the elastic member 2, that is, all the blades may swing.

Referring to fig. 10, in one embodiment, the cutter shaft 1 includes a first cutter shaft 11 and a second cutter shaft 12 sleeved on the first cutter shaft. In fig. 10, the first cutter shaft 11 is provided with the second blade 4, and the second cutter shaft 12 is provided with the elastic member 2 and the first blade 3.

Through the arrangement, the second cutter shaft 12 is sleeved on the first cutter shaft 11, so that the first cutter shaft 11 and the second cutter shaft 12 can be detachably assembled, and the stirring cutter assembly 10 is convenient to clean.

Further, based on the teaching of the rotary reciprocation structure illustrated in fig. 10, the skilled person will understand that the first cutter shaft 11 and the second cutter shaft 12 are provided with rotary reciprocation structures (not limited to the rotary reciprocation structure described later) irrespective of the respective configurations of the first cutter shaft 11 and the second cutter shaft 12, and that the second cutter shaft 12 reciprocates up and down while rotating about the rotation center line of the first cutter shaft 11 in the case where the first cutter shaft 11 rotates. The specific structures of the two rotary reciprocating structures are described below.

Referring to fig. 10, the first cutter shaft 11 is provided with a ring of annular sliding grooves 111, and the second cutter shaft 12 is provided with a mating portion (the mating portion is not illustrated in the drawing, but a skilled person can understand the structure of the mating portion according to the mating relationship between the mating portion and the annular sliding grooves 111). In another embodiment, the first cutter shaft 11 is provided with a mating portion, and the second cutter shaft 12 is provided with the annular chute 111. The rotary reciprocation structure includes the annular chute 111 and a mating portion. Regardless of which of the first cutter shaft 11 and the second cutter shaft 12 the annular chute 111 is disposed on, the track of the annular chute 111 extending in the circumferential direction is in an up-and-down undulating shape. Under the condition that the first cutter shaft 11 rotates, the matching part moves relative to the chute, so that the second cutter shaft 12 is driven to rotate around the rotation center line of the first cutter shaft 11, and meanwhile, the second cutter shaft 12 reciprocates up and down along the first cutter shaft 11. In the embodiment of the present application, the first cutter shaft 11 is driven by the motor 201, and the second cutter shaft 12 serves as a driving member and a driven member, and thus, the engaging portion moves with respect to the annular chute 111. In the case where the first cutter shaft 11 is provided with the mating portion and the second cutter shaft 12 is provided with the annular chute 111, the annular chute 111 moves relative to the mating portion. In either case, the second cutter shaft 12 finally reciprocates up and down in the axial direction of the first cutter shaft 11 while rotating with respect to the rotation center line of the first cutter shaft 11, and further, drives the first blade 3 provided on the second cutter shaft 12 to reciprocate up and down while rotating.

As set forth above, since the rotary reciprocating structure includes the chute and the mating portion, the rotary reciprocating structure is simple in structure, and the second cutter shaft can move smoothly by matching the annular chute 111 with the mating portion, and in addition, the first blade 3 also swings during the movement of the second cutter shaft 12 and the up-down reciprocation, so that the food material is more uniform.

In some embodiments, referring to fig. 4, in case that the cutter shaft 1 includes a first cutter shaft 11 and a second cutter shaft 12, an anti-rotation structure 15 is provided between the first cutter shaft 11 and the second cutter shaft 12 to allow the first cutter shaft 11 and the second cutter shaft 12 to rotate synchronously. The anti-rotation structure 15 is not limited, for example, a flat structure, and referring to fig. 4, 3, 7 and 8, the anti-rotation structure 15 includes a groove 151 disposed on the first cutter shaft 11 and a rib 152 disposed on the second cutter shaft 12. The ribs 152 are located in the grooves 151 to form the anti-rotation structure 15, so that the first cutter shaft 11 and the second cutter shaft 12 rotate synchronously.

In the above arrangement, the stirring blade assembly not only can realize uniform mixing, but also can be assembled and disassembled by the first cutter shaft 11 and the second cutter shaft 12, so that the stirring blade assembly 10 is convenient to clean.

The stirring blade assemblies shown in fig. 10 and fig. 4 each include the second blade 4, and in some embodiments, the stirring blade assembly that does not include the second blade 4 (i.e., the blades of the stirring blade assembly are all the first blades 3) may also adopt the above arrangement, where the cutter shaft 1 includes a first cutter shaft 11 and a second cutter shaft 12 sleeved on the first cutter shaft 11. Of the first cutter shaft 11 and the second cutter shaft 12, at least the second cutter shaft 12 is provided with the elastic member 2 and the first blade 3, that is, in this stirring cutter assembly 10, the first cutter shaft 11 and the second cutter shaft 12 are provided with the elastic member 2 and the first blade 3, or only the second cutter shaft 12 is provided with the elastic member 2 and the first blade 3. In the foregoing two cases, the rotary reciprocating structure or the anti-rotation structure 15 may be disposed between the first cutter shaft 11 and the second cutter shaft 12. Since only the blade arrangement is different (i.e., the blades of this embodiment are all the first blades 3 that can swing), the specific structure of the rotary reciprocating structure or the anti-rotation structure 15 is the same as that described above, and will not be described again.

On the other hand, referring to fig. 1 and 2, the application discloses a food processor. The food processor includes a main machine 20, a food material container 30, and any one of the blender blade assemblies 10 described above. The main machine 20 comprises a motor 201, the motor 201 is connected with the cutter shaft, and the cutter blade arranged on the cutter shaft is driven to rotate in the food container 30. Of course, in the case where the cutter shaft 1 includes two sections of the first cutter shaft 11 and the second cutter shaft 12, the first cutter shaft 11 is driven by the motor 201 as a driving shaft. In case that the cutter shaft 1 has only one segment, the cutter shaft 1 is driven by the motor 201. In fig. 1 and 2 described above, the food processor is a meat grinder (which may also be a meat grinder), and thus, further includes a bowl cover 40. The bowl cover 40 is adapted to cover the food material container 30 (also referred to in the industry as a mixing bowl). The main body 20 is placed on the bowl cover 40. In an embodiment, the food processor may be a juice extractor, etc., and the main machine 20 is disposed below the food container 30.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
