Description

Technical Field

[0001] The utility model relates to the technical field of food processing knives, in particular to a food processor knife set. Background Art

[0002] Prior art, such as Chinese utility model patent publication number CN 102068193B, discloses a mixing knife for a food processor, comprising a blade shaft with an upper blade and a lower blade alternately disposed thereon. The upper and lower blades are mounted on a blade holder, which is detachably connected to the blade shaft via a snap-fit ​​mechanism. The upper blade or the lower blade, respectively, comprises a first blade and a second blade that are parallel and rotationally symmetrical to each other; the upper blade and the lower blade are horizontally offset by a predetermined angle.

[0003] Based on the above, in the prior art, the blade holder utilizes a snap-fit ​​mechanism for a removable connection to the blade shaft. This connection structure presents a problem: if the snap-fit ​​mechanism is loosened, the blade holder can move upward relative to the blade shaft, causing the blade to separate from the shaft. Besides the snap-fit ​​mechanism, there are no other retaining structures, resulting in a lack of stability. Blade separation not only affects the normal operation of the machine but also poses a safety hazard. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention provides a food processor knife set.

[0005] A food processor knife set designed for this purpose includes a knife shaft and a knife. The knife shaft is provided with a polygonal limit column, an avoidance portion and a mounting portion in sequence from top to bottom.

[0006] The cutter comprises a connecting portion and a stirring element arranged on the connecting portion;

[0007] The connecting portion and the mounting portion are connected via a snap-fit ​​structure and the two can rotate relative to each other;

[0008] A limiting plate is provided at the upper end of the connecting portion, the lower surface of the limiting plate is in contact with the upper surface of the mounting portion for limiting position, and the limiting plate is provided with a polygonal hole;

[0009] The limiting plate is configured such that when the connecting portion and the mounting portion are engaged with each other, the polygonal hole and the polygonal limiting column are offset from each other, so that the polygonal limiting column constrains the limiting plate from moving upward relative to the tool axis.

[0010] Preferably, the connecting portion and the mounting portion are both arranged in an annular shape, and the connecting portion is sleeved on the outside of the mounting portion.

[0011] Preferably, the snap-fit ​​structure includes a plurality of first snap-fitting portions arranged in a circumferential array on the peripheral wall of the mounting portion.

[0012] The connecting portion is provided with second snap-fitting portions along a circumferential array and snap-fitting with the first snap-fitting portions;

[0013] Preferably, a positioning shaft is provided at the upper end of the knife shaft.

[0014] Preferably, the stirring element is a blade.

[0015] Preferably, the stirring element is a stirring disk for stirring egg white or for frothing milk.

[0016] Preferably, the polygonal hole and the polygonal limiting column both have a hexagonal structure.

[0017] Compared with the prior art, the present invention is characterized in that a limit plate is provided at the upper end of the connecting portion, and the lower surface of the limit plate is fitted and limited with the upper surface of the mounting portion, and the limit plate is provided with a polygonal hole. During assembly, the polygonal hole and the polygonal limit column are correspondingly plugged in. When the connecting portion is plugged downward to the end, the limit plate and the upper surface of the mounting portion are fitted and limited, the limit plate and the avoidance portion are at the same height, and the limit plate and the polygonal limit column are in an upper and lower positional relationship. At this time, by rotating the connecting portion, the connecting portion and the mounting portion are mutually engaged through the snap-fit ​​structure. During this process, since the connecting portion rotates relative to the tool shaft, the polygonal hole and the polygonal limit column are misaligned, and the edges of the two do not correspond. Therefore, the lower surface of the polygonal limit column can abut the upper surface of the limit plate to constrain the connecting portion from moving upward relative to the mounting portion. This constrains the upward movement of the tool relative to the tool shaft, achieving the effect of limiting and preventing disengagement. Compared with the existing single snap-fit ​​connection, both stability and safety are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See also Figure 1-Figure 7 A food processor knife set includes a knife shaft 10 and a knife 20. The knife shaft 10 is provided with a polygonal limiting column 120, an avoidance portion 130 and a mounting portion 110 in order from top to bottom.

[0027] The cutter 20 includes a connecting portion 210 and a stirring element 220 disposed on the connecting portion 210;

[0028] The connecting portion 210 is connected to the mounting portion 110 via a snap-fit ​​structure and the two can rotate relative to each other;

[0029] A limiting plate 230 is provided at the upper end of the connecting portion 210. The lower surface of the limiting plate 230 is in contact with the upper surface of the mounting portion 110 for limiting position. The limiting plate 230 is provided with a polygonal hole 231.

[0030] The limit plate 230 is configured such that when the connecting portion 210 and the mounting portion 110 are engaged with each other, the polygonal hole 231 and the polygonal limit column 120 are offset from each other, so that the polygonal limit column 120 constrains the limit plate 230 to move upward relative to the knife shaft 10.

[0031] See also Figure 1 During assembly, the polygonal holes are plugged into the polygonal limiting posts. When the connecting portion is plugged down to the end, the limiting plate and the upper surface of the mounting portion are aligned and limited. The limiting plate and the avoidance portion are at the same height, and the limiting plate and the polygonal limiting post are in an upper and lower position relationship.

[0032] See also Figure 2 By rotating the connecting part, the connecting part and the mounting part are engaged with each other through the clamping structure. In this process, since the connecting part rotates relative to the knife shaft, the polygonal hole and the polygonal limiting column are misaligned, and the edges of the two do not correspond to each other, so the lower surface of the polygonal limiting column can abut the upper surface of the limiting plate to constrain the connecting part to move upward relative to the mounting part.

[0033] In the present invention, the avoidance portion 130 is used to connect the polygonal limit column 120 and the mounting portion 110. Its function is that when the tool 20 and the tool shaft 10 are fully inserted into place, in this state, the avoidance portion 130 and the limit plate 230 are at the same height, and the limit plate 230 provided with a polygonal hole can be rotated relative to the avoidance portion 130 along the axis of the tool shaft 10. This rotation can make the connecting portion 210 and the mounting portion 110 clamped, and at the same time make the polygonal hole 231 and the polygonal limit column 120 offset, and the edges of the two do not correspond to each other, so as to achieve offset limiting.

[0034] In the present invention, the connecting portion 210 and the mounting portion 110 are both annularly arranged, and the connecting portion 210 is sleeved on the outside of the mounting portion 110 . The limiting plate 230 is arranged on the upper surface of the connecting portion 210 .

[0035] See also Figure 4 and Figure 6 The snap-fit ​​structure includes a plurality of first snap-fitting portions 140 arranged in a circumferential array on the peripheral wall of the mounting portion 110 .

[0036] The connecting portion 210 is provided with a second snap-fitting portion 211 along a circumferential array that is snap-fitted with the first snap-fitting portion 140 ;

[0037] Furthermore, the first engaging portion 140 is a buckle, and the second buckle fitting portion 211 is a slot. During assembly, the connecting portion 210 is rotated relative to the mounting portion 110, so that the buckle can be screwed into the slot to form a snap fit.

[0038] See also Figure 1 and Figure 2 The upper end of the knife shaft 10 is provided with a positioning shaft 100. The function of the positioning shaft 100 is to be used for plugging and positioning with the cooking cup cover.

[0039] In the present invention, the stirring element 220 is a blade.

[0040] In the present invention, the stirring element 220 is a stirring plate for stirring egg white or for frothing milk.

[0041] In the present invention, the polygonal hole 231 and the polygonal limiting column 120 both have a hexagonal structure.
