In other examples of the utility model, the lid assembly 3 may also be rotatably disposed on the cup 1.

The driving motor 40 is connected to the connecting shaft 20 to drive the connecting shaft 20 to rotate. In some examples of the utility model, a containing cavity is arranged in the cup cover assembly 3, and the driving motor 40 is arranged in the containing cavity. Specifically, when the driving motor 40 is in transmission fit with the connecting shaft 20, the driving motor 40 drives the connecting shaft 20 to rotate so as to drive the plurality of stirring knives 21 to cut and stir the food.

It should be noted that, in the process of cutting and stirring the food material by the stirring knife 21, the food material is easy to deposit on the side wall of the cup bottom after being stirred, and then large particles exist, which results in poor stirring and crushing effects. In order to solve the above technical problem, as shown in fig. 1 and 13 to 18, the stirring blade 21 located at the lowermost position includes a main body portion 211 and a bending portion 212, the main body portion 211 is connected to the connecting shaft 20, the main body portion 211 can extend horizontally or be disposed obliquely with respect to a horizontal plane, the bending portion 212 is connected to an end portion of the main body portion 211 away from the connecting shaft 20, the bending portion 212 extends upward, the bending portion 212 extends obliquely toward an inner wall of the stirring space 10, an included angle between the bending portion 212 and the main body portion 211 is θ, where 120 ≦ θ ≦ 150 °. Particularly, rotate at stirring sword 21 and cut the in-process of stirring to food, bend 212 and can bring a slant thrust along the circumferencial direction for the food of the internal face of stirred space 10, can drive the food of bottom and side and upwards roll like this, avoid food at bottom and lateral wall deposit, simultaneously, the edible material of upset and the cutting probability increase of stirring sword 21, have promoted the crushing effect of stirring.

According to the food processor 1000 of the embodiment of the utility model, the bending part 212 is arranged to drive the food at the bottom and the side surface to roll upwards, so as to avoid the food from depositing at the bottom and the side wall, and meanwhile, the specific included angle is limited, so that the situation that the food cannot be driven to roll upwards because the included angle is too small can be avoided, the situation that the food cannot be driven to roll upwards because the included angle is too large can be avoided, and the food deposition is further avoided.

As shown in fig. 14 and 16, in some embodiments of the present invention, the minimum distance between the bent portion 212 and the bottom wall of the stirring space 10 is h, wherein 1mm < h <25mm, for example, h may be 5mm, 10mm, 12mm, 16mm, 19mm, 20mm, 23mm, etc. Preferably, 5mm < h < 15mm, e.g., h can be 10mm, 12mm, 14mm, etc. Therefore, by setting the range of the minimum distance h, the phenomenon that the food at the bottom cannot be provided with upward rolling force due to the overhigh height of the bending part 212 is avoided, and the food deposition can be further avoided.

As shown in fig. 17, in some embodiments of the present invention, the minimum spacing between bend 212 and the inner wall of mixing space 10 is s, where 4mm < s <30 mm. For example, s can be 5mm, 8mm, 12mm, 18mm, 21mm, 25mm, and the like. Preferably, 5mm ≦ s ≦ 15mm, e.g., s may be 6mm, 8mm, 12mm, 14mm, etc. Therefore, by setting the range of the minimum distance s, the phenomenon that the food at the bottom cannot be provided with upward rolling acting force due to too large or too small distance between the bent part 212 and the cup body 1 can be avoided, and food deposition can be further avoided.

In some specific examples of the present invention, as shown in fig. 13 and 15, in the circumferential direction of the connecting shaft 20, two ends of the body portion 211 are a material inlet end and a material outlet end, respectively, and orthogonal projections of the material inlet end and the material outlet end on a projection plane, which is a plane parallel to the cross section of the connecting shaft 20, are formed as straight lines. That is, the material incoming end and the material outgoing end of the body portion 211 are formed as straight edges. Thereby facilitating the forming of the stirring blade 21. Further, the remaining agitating blades 21 are formed as blades having a curved shape, which can improve the agitating effect of the agitating assembly 2.

Preferably, t2 satisfies 0 < t2 ≦ 4mm, e.g., t2 is 1mm, 2mm, 3.5mm, etc. Therefore, by limiting the width of the blade 210, the structural strength of the stirring blade 21 can be improved on the basis of ensuring that the blade 210 effectively cuts the food material.

For example, the ratio of t/t1 may be 2.5, 3, 3.5, etc. Thereby through the ratio of the thickness minimum of injecing cutting edge 210 and the thickness of stirring sword 21, can further enough guarantee that the thickness of cutting edge 210 is unlikely to too big, avoid machining efficiency lower, can guarantee again that the thickness of cutting edge 210 is unlikely to the undersize, avoid cutting the material too fine and smooth, eat the material and be cut the back tentatively, cutting edge 210 and eat the material striking effect obvious. Under the action of impact/pulling, protein separated out by cell rupture is easy to be adhered to glue, the prepared meatballs are more pliable, and the method can be adapted to application scenes of processing meatballs, muddy flesh and the like, so that the processing efficiency and the effect of processing the meatballs and the muddy flesh can be considered.
