The obtuse angle formed by the first connecting body 2311 and the first bending body 2312 in a matching mode is alpha 1, wherein alpha 1 is larger than 90 degrees and smaller than or equal to 160 degrees, the first connecting body 2311 and the first bending body 2312 are matched to form the obtuse angle, the situation that the first bending body 2312 and the cutter shaft 1 are arranged in parallel in the axial direction and stirring difficulty is caused, food materials are accumulated between the first bending body 2312 and the first connecting body 2311 is caused, the obtuse angle formed by the first connecting body 2311 and the first bending body 2312 in a matching mode is limited within the range, the fact that the obtuse angle is too large is avoided, and under the condition that the lengths of the first bending bodies 2312 are the same, the fact that the distance between one end, away from the first connecting body 2311, of the first bending body 2312 and the bottom of the cup body is too far, the fact that the distance between the first extending portion 232 and the bottom of the cup body is too far is caused, and the dry grinding effect is poor; and under the condition that the distance between one end of the first bending body 2312, which is far away from the first connecting body 2311, and the bottom of the cup body is certain, the upper limit of the obtuse angle is limited, so that the length of the first bending body 2312 is favorably shortened, and the subsequent design of the size of the cup body and the size of the first extending part 232 is favorably realized.

Similarly, the second connection portion 241 of the fourth blade 24 may include a second connection body 2411 and a second bending body 2412, the second connection body 2411 is connected to the blade root 25, the second bending body 2412 is connected to an end of the second connection body 2411 away from the blade root 25, and the second bending body 2412 is bent toward the second end 12 and away from the blade root 25, as shown in fig. 2, the second bending body 2412 may be bent from top to bottom toward a direction away from the blade root 25, and an end of the second bending body 2412 away from the second connection body 2411 is further connected to the second extension portion 242. The obtuse angle formed by the second connector 2411 and the second bending body 2412 in a matching manner is alpha 2, wherein alpha 2 is more than 90 degrees and less than or equal to 160 degrees, the second connector 2411 and the second bending body 2412 are matched to form the obtuse angle, so that the second bending body 2412 and the cutter shaft 1 are prevented from being axially arranged in parallel, the stirring difficulty is improved, food materials are accumulated between the second bending body 2412 and the second connector 2411, the obtuse angle formed by the second connector 2411 and the second bending body 2412 in a matching manner is limited in the range, and the fact that the obtuse angle is too large is avoided, and under the condition that the lengths of the second bending bodies 2412 are the same, the distance between one end of the second bending body 2412, which is far away from the second connector 2411, and the bottom of the cup body is too far, the distance between the second extending part 242 and the bottom of the cup body is too far, so that the dry grinding effect is poor is caused; and under the condition that the distance between one end of the second bending body 2412 far away from the second connector 2411 and the bottom of the cup body is fixed, the upper limit of the obtuse angle is limited, so that the length of the second bending body 2412 is favorably shortened, and the subsequent design of the size of the cup body and the size of the second extension part 242 is favorably realized.

The first connecting portion 231 and the first extending portion 232 are matched to form an obtuse angle α 3, wherein α 3 is more than 90 degrees and less than or equal to 160 degrees, so that the obtuse angle α 3 formed by matching the first connecting portion 231 and the first extending portion 232 is subjected to parameter limitation, and since the first extending portion 232 is perpendicular to the axial direction of the cutter shaft 1, the length parameter and the inclination parameter of the first bending body 2312 can be adjusted through the obtuse angle α 3, so that the third blade 23 is integrally in a relatively attractive appearance environment. Similarly, the second connecting portion 241 and the second extending portion 242 cooperate to form an obtuse angle α 4, wherein α 4 is greater than 90 ° < α 4 and less than or equal to 160 °, so that the obtuse angle α 3 formed by the second connecting portion 241 and the second extending portion 242 cooperating to each other is limited, and since the second extending portion 242 is perpendicular to the axial direction of the arbor 1, the length parameter and the inclination parameter of the second bending body 2412 can be adjusted through the obtuse angle α 3, so that the entire third blade 23 is in a relatively beautiful appearance environment.

The first extending portion 232 and the first bending portion 233 are matched to form an obtuse angle alpha 5, wherein alpha 5 is more than 90 degrees and less than or equal to 160 degrees, so that the obtuse angle alpha 5 formed by matching the first extending portion 232 and the first bending portion 233 is subjected to parameter limitation, on one hand, the obtuse angle is formed, so that the first bending portion 233 can be ensured to be bent towards the direction away from the knife root 25, and therefore the food material between the inner wall of the cup body and the third knife blade 23 can be turned and thrown conveniently, and the phenomenon that the turning and throwing effect is poor due to the fact that the first bending portion 233 is too gentle can be avoided through limitation on the upper limit value of the obtuse angle alpha 5. The second extending portion 242 and the second bending portion 243 are matched to form an obtuse angle α 6, wherein α 6 is more than 90 degrees and less than or equal to 160 degrees, so that the obtuse angle α 6 formed by matching the second extending portion 242 and the second bending portion 243 is subjected to parameter limitation, on one hand, the obtuse angle is formed, so that the second bending portion 243 can be ensured to be bent towards the direction away from the knife root 25, and therefore, the food material between the inner wall of the cup body and the fourth knife blade 24 can be turned and thrown in the following process, and the problem of poor turning and throwing effects caused by the fact that the second bending portion 243 is too gentle can be avoided through limitation on the upper limit value of the obtuse angle α 6.

Specifically, the food processor 200 may further include a cup 202 and a large shell 201, and the cup 202 may be assembled to the large shell 201. For example, in fig. 5, the bowl 202 may be assembled inside the large shell 201, but in other embodiments, the bowl 202 may be assembled on the top of the open end of the large shell 201; at least a portion of motor assembly 203 may be disposed within bodice housing 201 and motor assembly 203 may be fixedly coupled to bodice housing 201, with a motor shaft of motor assembly 203 extending into cup 202, with blade 2 of knife assembly 100 positioned within cup 202, and with arbor 1 of knife assembly 100 being directly drivingly coupled to the motor shaft. For example, the motor shaft may comprise a threaded bore into which the arbor 1 may extend for direct drive connection with the motor shaft. In other embodiments, the knife shaft 1 may extend into the large housing 201 to be directly connected with the motor shaft in a driving manner, which is not limited in the present application.

It can be understood that, in order to improve the processing effect and the taste of the food material, the cup body 202 may include one or more turbulence ribs 2021 protruding from the outer side to the inner side, for example, the number of the turbulence ribs 2021 may be 4 or more than 4, the minimum distance between each turbulence rib 2021 and the bottom of the cup body 202 is L6, the minimum distance L6 may be greater than or equal to 5mm, and less than or equal to 30mm, that is, 5mm is greater than or equal to L6 is less than or equal to 30mm, so as to leave enough space between the turbulence ribs 2021 and the bottom of the cup body 202 for rolling the food material, thereby improving the processing effect.
