[0002] A food processor is a commonly used kitchen appliance that can quickly chop and blend ingredients. In practice, it is widely used in processes such as cutting, stirring, mixing, beating, grinding and grating.

[0003] The food processor includes a main unit and a container. After the food is placed in the container, the main unit drives the knife group to rotate in the container to chop and stir the food. However, the blades on the knife group can only rotate around a fixed position, and the rotation height of the blades in the container is fixed. The contact between the blades and the food mainly depends on the food being stirred and actively moving into the cutting range of the blades. In this way, the chopping and stirring efficiency of the food is low.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a rotating knife set and a food processor to improve the working efficiency of the food processor.

[0008] Its further technical solution is that it also includes a connecting hole, which is arranged on the rotating shaft or the second sleeve; a boss, which is arranged corresponding to the connecting hole on a structure that matches the structure where the connecting hole is set, and matches the connecting hole; wherein, when the connecting hole is arranged on the rotating shaft, the matching structure is the second sleeve; when the connecting hole is arranged on the second sleeve, the matching structure is the rotating shaft.

[0009] A further technical solution is that the contact surface between the connecting hole and the boss can be a plane or a curved surface.

[0010] A further technical solution is that when the connecting hole is arranged on the second sleeve, a slide groove is also arranged on the second sleeve, and the slide groove is connected to the connecting hole and extends to the lower end surface of the second sleeve.

[0011] A further technical solution is that the first limit rail and the second limit rail are parallel to each other, two wave crests and two wave troughs are formed on the undulating first limit rail, and the two wave crests and the two wave troughs are arranged alternately.

[0012] A further technical solution is that a stirring member is provided on the rotating shaft, the first shaft sleeve and the second shaft sleeve, and the stirring member is a blade or a stirring rod.

[0013] A further technical solution is that a first extension portion is provided at one end of the first sleeve close to the first limiting rail, and the first slide rail is provided on the inner side of the first extension portion.

[0017] (1) The rotary knife assembly in the utility model has a rotating shaft connected to the second sleeve, and the movement of the first sleeve is limited by the first limit rail on the rotating shaft and the second limit rail on the second sleeve. When the rotating shaft rotates, the first slide rail slides on the first limit rail, and the second slide rail slides on the second limit rail, transmitting torque and axial thrust to the sleeve, driving the first sleeve to rotate and reciprocate up and down along the rotating shaft. Correspondingly, the stirring member on the first sleeve will rotate around the rotating shaft and reciprocate up and down along the rotating shaft, stirring the food and changing the cutting position at all times, thereby improving the chopping and stirring efficiency.

[0018] (2) Furthermore, the second sleeve is also provided with a stirring member, and the additional stirring member improves the chopping and mixing efficiency. The second sleeve is connected to the rotating shaft through the boss and the connecting hole, and the second sleeve can be easily disassembled and assembled.

[0019] (3) Further, a first extension portion and a second extension portion are provided on the first sleeve, a first slide rail is provided on the inner side of the first extension portion, and a second slide rail is provided on the inner side of the second extension portion. When the first slide rail cooperates with the first limit rail, the first extension portion limits the circumferential runout of the first sleeve on the rotating shaft. When the second slide rail cooperates with the second limit rail, the second extension portion limits the circumferential runout of the first sleeve on the rotating shaft. The first extension portion and the second extension portion together increase the stability of the rotating knife assembly during rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1

[0034] Figure 1 The exploded structure diagram of the rotary knife set in the first embodiment of the present invention is shown. Figure 1 A rotary knife assembly comprises a rotating shaft 1, a first sleeve 2 sleeved on the rotating shaft 1 and an agitator 4 arranged on the rotating shaft 1. A second sleeve 3 is arranged on the rotating shaft 1 above the first sleeve 2. A first undulating limit rail 11 is arranged circumferentially on the rotating shaft 1, and an undulating first slide rail 21 is arranged at the lower part of the first sleeve 2 to cooperate with the first limit rail 11. A second undulating limit rail 33 is arranged circumferentially on the second sleeve 3, and an undulating second slide rail 22 is arranged at the upper part of the first sleeve 2 to cooperate with the first limit rail 11. By rotating the rotating shaft 1, the first limit rail 11 on the rotating shaft 1 and the second limit rail 33 on the second sleeve 3 alternately transmit torque and thrust to the first slide rail 21 and the second slide rail 22, driving the first sleeve 2 to rotate around the rotating shaft 1 and reciprocate up and down along the rotating shaft 1. The agitator 4 fixed on the first sleeve 2 rotates and moves synchronously with the first sleeve 2, stirs and chops the food and continuously changes its own working position, thereby improving the chopping and mixing efficiency.

[0035] The specific structures of the rotating shaft 1, the first sleeve 2 and the second sleeve 3 are described as follows:

[0036] Figure 2 The figure shows a three-dimensional structure diagram of the second shaft sleeve of the rotary knife assembly in the first embodiment of the present utility model when viewed from above. Figure 1 and Figure 2 The second sleeve 3 is provided with a connecting hole 31 and a slide groove 32, and the slide groove 32 connects the connecting hole 31 and the lower end surface of the second sleeve 3. A boss 13 is provided on the rotating shaft 1 to snap into the connecting hole 31, and fix the second sleeve 3 on the rotating shaft 1. After the boss 13 snaps into the connecting hole 31 along the slide groove 32, the rotating shaft 1 is rotated, and the boss 13 on the rotating shaft 1 will drive the second sleeve 3 and the rotating shaft 1 to rotate synchronously. The connection structure between the second sleeve 3 and the rotating shaft 1 is simple, which is convenient for installing and removing the second sleeve 3 from the rotating shaft 1. The second sleeve 3 can be quickly replaced according to different food materials, so as to replace different stirring members 4, so as to improve the chopping and stirring effects in a targeted manner.

[0037] In addition, the rotating shaft 1, the first sleeve 2 and the second sleeve 3 are all provided with agitators 4. The number of agitators 4 is increased, which improves the chopping and stirring efficiency. The agitator 4 is a blade or a stirring rod, and its material can be metal or plastic. Among them, the metal blade has a better chopping effect, and the plastic stirring rod is lighter, has good insulation and is easy to clean, and can be freely selected according to the usage scenario.

[0038] The specific structures of the first limiting rail 11, the second limiting rail 33, the first slide rail 21 and the second slide rail 22 are described as follows:

[0039] The first limit rail 11 and the second limit rail 33 are parallel to each other, and two wave crests 111 and two wave troughs 112 are formed on the undulating first limit rail 11, and the two wave crests 111 and the two wave troughs 112 are arranged alternately. When the first slide rail 21 slides one circle along the first limit rail 11, the first sleeve 2 will reciprocate up and down two times along the rotating shaft 1. When the second slide rail 22 slides one circle along the second limit rail 33, the first sleeve 2 will reciprocate up and down two times along the rotating shaft 1. The stirring member 4 fixed on the first sleeve 2 stirs the food and continuously changes the rotation position. At the same time, when the first slide rail 21 is limited to slide one circle along the first limit rail 11, or the second slide rail 22 slides one circle along the second limit rail 33, the number of times the first sleeve 2 reciprocates up and down is limited to two times, so as to avoid the frequency of the first sleeve 2 moving up and down being too high, which affects the running stability.

[0040] The specific working process of the utility model is as follows:

[0041] Under the action of gravity, the first sleeve 2 moves to the bottom along the rotating shaft 1, that is, the first slide rail 21 contacts the first limit rail 11. During shredding, the rotating shaft 1 rotates, and the rotating shaft 1 drives the second sleeve 3 to rotate synchronously through the boss 13. Through the interaction of friction, the first limit rail 11 transmits torque to the contacted first slide rail 21, driving the first sleeve 2 to rotate around the rotating shaft 1 for shredding and stirring. Affected by the resistance, the rotation speed of the first sleeve 2 will be lower than the rotation speed of the rotating shaft 1, and the first slide rail 21 slides along the undulating track surface of the first limit rail 11, so that the first sleeve 2 rotates around the rotating shaft 1 while sliding up and down along the axial direction of the rotating shaft 1. When the trough 112 of the first slide rail 21 slides along the trough 112 of the first limit rail 11 to the top of the crest 111 of the first limit rail 11, under the influence of inertia, the first sleeve 2 will continue to move upward along the rotating shaft 1 until the second slide rail 22 contacts the second limit rail 33. Then the second slide rail 22 slides along the second limit rail 33, and the first sleeve 2 moves up and down along the undulation of the second limit rail 33 until the wave crest 111 of the second slide rail 22 moves to the bottom of the wave trough 112 of the second limit rail 33. Under the influence of the inertial force, the first sleeve 2 continues to move downward along the rotating shaft 1. Until the first slide rail 21 contacts the first limit rail 11, the first sleeve 2 moves up and down along the undulation of the first limit rail 11. The rotating shaft 1 is continuously rotated, and the first sleeve 2 rotates around the rotating shaft 1 and reciprocates up and down along the axial direction of the rotating shaft 1, driving the agitator 4 fixed on the first sleeve 2 to rotate around the rotating shaft 1 and reciprocate up and down along the rotating shaft 1.

[0042] Embodiment 2

[0043] Figure 3 A schematic diagram of the three-dimensional structure of the first shaft sleeve of the rotary knife assembly in the second embodiment of the utility model is shown. Figure 4 The figure shows a schematic diagram of the three-dimensional structure of the first shaft sleeve of the rotary knife assembly in the second embodiment of the present utility model when viewed from above. Figure 3 and Figure 4 Based on the first embodiment, the second embodiment discloses a rotary knife set, wherein a first extension portion 23 is provided at one end of the first sleeve 2 close to the first limit rail 11, and the first slide rail 21 is provided on the inner side of the first extension portion 23. When the first slide rail 21 cooperates with the first limit rail 11, the first limit rail 11 will enter the inner side of the first extension portion 23. When the first sleeve 2 rotates around the rotating shaft 1, the inner side of the first extension portion 23 will limit the position of the outer side of the first limit rail 11, that is, limit the circumferential runout of the first sleeve 2 when rotating around the rotating shaft 1, and increase the stability of the rotary knife set during operation.

[0044] The first sleeve 2 is provided with a second extension portion 24 at one end close to the second limit rail 33, and the second slide rail 22 is provided inside the second extension portion 24. When the second slide rail 22 cooperates with the second limit rail 33, the second limit rail 33 will enter the inside of the second extension portion 24. When the first sleeve 2 rotates around the rotating shaft 1, the inside of the second extension portion 24 will limit the position of the outside of the second limit rail 33, that is, limit the circumferential runout of the first sleeve 2 when rotating around the rotating shaft 1, and increase the stability of the rotary knife assembly during operation.

[0045] Embodiment 3

[0046] Figure 5 The three-dimensional structure diagram of the rotating shaft of the rotating knife group in the third embodiment of the utility model is shown. Figure 5 Based on the first embodiment, the third embodiment discloses a rotary knife set, wherein a third extension portion 12 is provided on the rotary shaft 1, and a first limit rail 11 is provided on the inner side of the third extension portion 12. When the first limit rail 11 and the first slide rail 21 cooperate, the first slide rail 21 will enter the inner side of the third extension portion 12. When the first sleeve 2 rotates around the rotary shaft 1, the inner side of the third extension portion 12 will limit the position of the outer side of the first slide rail 21, that is, limit the circumferential runout of the first sleeve 2 when rotating around the rotary shaft 1, and increase the stability of the rotary knife set during operation.

[0047] Embodiment 4

[0048] Figure 6 A schematic diagram of the exploded structure of the rotary knife group in the fourth embodiment of the utility model is shown. Figure 7 The schematic diagram of the three-dimensional structure of the second shaft sleeve of the rotating knife group in the fourth embodiment of the utility model is shown. Figure 6 and Figure 7 Based on the first embodiment, the fourth embodiment discloses a rotary knife set, wherein the connection hole 31 is provided on the rotating shaft 1, and the second sleeve 3 is provided with a boss 13 which is inserted into the connection hole 31. The rotating shaft 1 has a large deadweight and good stability. When the connection hole 31 is provided on the rotating shaft 1, the balance of the center of gravity of the rotating shaft 1 when rotating is less affected, and the influence of the connection hole 31 on the balance of the rotary knife set is reduced, thereby ensuring the stability of the rotation of the rotary knife set.

[0049] Please refer to Figure 6 and Figure 7 , the boss 13 enters the connecting hole 31 along the slide groove 32, limits the position of the rotating shaft 1 on the second sleeve 3, and the installation method is simple. The surface where the connecting hole 31 and the boss 13 contact can be a plane or an arc surface. The boss 13 can be limited by the contact between the connecting hole 31 and the boss 13. When the surface where the connecting hole 31 contacts the boss 13 is an arc surface, the contact area between the connecting hole 31 and the boss 13 can be increased to ensure stability.

[0050] Embodiment 5

[0051] Figure 8 The cross-sectional structure diagram of the food processor of the fifth embodiment of the present invention is shown. Figure 8 ,

[0052] Based on the first, second, third and fourth embodiments, the fifth embodiment discloses a food processor, including a main unit 5, a container 6 and a rotating knife group. One end of the rotating shaft 1 in the rotating knife group is connected to the main unit 5, and the other end of the rotating shaft 1 extends into the container 6. The main unit 5 drives the rotating shaft 1 to rotate. The first sleeve 2 and the second sleeve 3 are arranged on the rotating shaft 1. The first sleeve 2 and the second sleeve 3 are located inside the container 6. The second sleeve 3 can be detachably connected to the rotating shaft 1. The second sleeve 3 and the rotating shaft 1 rotate synchronously. The main unit 5 can drive the second sleeve 3 and the rotating shaft 1 at the same time. The second sleeve 3 limits the upward movement range of the first sleeve 2, and the rotating shaft 1 limits the downward movement range of the first sleeve 2. When the main unit 5 drives the rotating shaft 1 to rotate, the first sleeve 2 will rotate around the rotating shaft 1 and move up and down along the rotating shaft 1, driving the agitator 4 fixed on the first sleeve 2 to rotate around the rotating shaft 1 and move up and down along the rotating shaft 1, thereby improving the efficiency and quality of food chopping and mixing.

[0053] It can be seen that in the above-mentioned rotating knife group, when the rotating shaft 1 rotates, the first sleeve 2 will rotate around the rotating shaft 1 and move back and forth along the rotating shaft 1, driving the stirring member 4 fixed on the first sleeve 2 to rotate around the rotating shaft 1 and move back and forth along the rotating shaft 1, so as to stir the food and change its own cutting position at all times, thereby improving the chopping and mixing efficiency of the food.

[0054] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
