AI Technical Summary
When existing food processors are in operation, ingredients with lower density tend to pile up on the top, resulting in low shredding efficiency and affecting work efficiency.
The suspended blade assembly includes a rotating shaft, a bushing, and an upper blade assembly. By setting undulating limit rails, the bushing moves up and down along the rotating shaft axis, driving the upper blade assembly to tilt. Combined with the container tilting design, this ensures that the blades can chop food over a wider range, and uses friction and gravity to drive the bushing to rotate synchronously.
It improves the chopping efficiency of the food processor, ensuring that the ingredients are fully stirred and chopped in the container, reducing food accumulation and improving work efficiency.

SUMMARY
[0005] In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a suspension knife group and a food processer to improve the working efficiency of the food processer.

[0009] The shaft sleeve is sleeved on the rotating shaft, and the lower part of the shaft sleeve is provided with a wavelike second limiting rail matched with the first limiting rail;
[0010] The upper knife assembly is arranged on the shaft sleeve;
[0011] When the rotating shaft rotates, the second limiting rail slides along the track surface of the first limiting rail, which promotes the shaft sleeve to rotate around the rotating shaft and move up and down along the axial direction of the rotating shaft;The upper knife assembly is arranged obliquely, and there is an acute angle between the upper knife assembly and the axis of the rotating shaft.
[0012] Further technical solutions are as follows: the rotating shaft comprises a first segment and a second segment;The first limiting rail is arranged on the second segment;Along the axial direction of the rotating shaft, a flat position is arranged on the first segment;The upper part of the shaft sleeve is provided with a limiting hole, and the limiting hole comprises a flat hole wall matched with the flat position;After the second limiting rail slides to the highest position of the first limiting rail, the flat position is connected to the limiting hole, so that the shaft sleeve and the rotating shaft rotate synchronously.
[0013] Further, a technical scheme is that an annular extension is arranged on the inner wall of the shaft sleeve and surrounds the axis of the shaft sleeve.
[0014] Further, a technical scheme is that a connecting section is arranged between the first section and the second section, and the diameter of the connecting section is smaller than the hole diameter of the limiting hole.
[0015] Further, a technical scheme is that the first limiting rail comprises two wave crests and two wave troughs, and the two wave crests and the two wave troughs are arranged alternately.
[0016] Further, a technical scheme is that the second limiting rail is arranged on the inner wall of the shaft sleeve.

[0021] The beneficial technical effects of the cooking machine are as follows:
[0022] (1) The lower part of the shaft sleeve of the floating knife set contacts the rotating shaft through the second limiting rail and the first limiting rail.

[0032] Embodiment one
[0033] Figure 1 An explosion structure schematic diagram of the suspension knife group in embodiment one of the present application is shown. Figure 2 A three-dimensional structure schematic diagram of the shaft sleeve in the suspension knife group in embodiment one of the present application is shown. Please refer to Figure 1 and Figure 2, the suspension knife group comprises a rotating shaft 1, a shaft sleeve 2 and an upper knife assembly 3. The rotating shaft 1 is provided with a first limit rail 131 in a wavy shape in the circumferential direction. The shaft sleeve 2 is sleeved on the rotating shaft 1, and the lower part of the shaft sleeve 2 is provided with a second limit rail 21 in a wavy shape matched with the first limit rail 131. The upper knife assembly 3 is arranged on the shaft sleeve 2. When the rotating shaft 1 rotates, the second limit rail 21 slides along the wavy track surface of the first limit rail 131, so as to drive the shaft sleeve 2 to rotate around the rotating shaft 1 and move up and down along the axial direction of the rotating shaft 1. The shaft sleeve 2 reciprocates up and down, and drives the upper knife assembly 3 to reciprocate up and down as well, so that the upper knife assembly 3 can shred in a larger range. The knife moves up and down, which can better stir the food materials, and thus improve the shredding efficiency of the suspension knife. The upper knife assembly 3 is arranged in an inclined manner, and there is an acute angle between the upper knife assembly 3 and the axis of the rotating shaft 1. Compared with the knife group arranged perpendicularly to the rotating shaft 1, the upper knife assembly 3 arranged in an inclined manner covers a larger area in the axial direction of the rotating shaft 1, and can fully stir the food materials at different heights. Meanwhile, when the parallelly arranged knife group is too close to the top and bottom of the container 6, the gap between the knife group and the container 6 is too small, which is not convenient for the food materials to enter, and the effective working volume of the container 6 is reduced. However, the upper knife assembly 3 arranged in an inclined manner allows only the end part to be close to the container 6. When the upper knife assembly 3 is close to the container 6 for shredding, the flow of the food materials is not hindered, and the internal space of the container 6 is fully utilized.
[0034] Please refer to Figure 1 and Figure 2 , the rotating shaft 1 comprises a first segment 11 and a second segment 13. The first limit rail 131 is arranged on the second segment 13. A flat position 111 is arranged on the first segment 11 in the axial direction of the rotating shaft 1. The upper part of the shaft sleeve 2 is provided with a limit hole 221, and the limit hole 221 comprises a flat hole wall matched with the flat position 111. After the second limit rail 21 slides to the highest position of the first limit rail 131, the flat position 111 is clamped with the limit hole 221, so that the shaft sleeve 2 and the rotating shaft 1 rotate synchronously. At this time, the upper knife assembly 3 can rotate at the same speed as the rotating shaft 1, and shred the food materials at high speed. When the rotating shaft 1 is stopped, the shaft sleeve 2 moves downward under the action of gravity, and the flat position 111 and the limit hole 221 are separated. Then the rotating shaft 1 is driven to rotate again, so as to realize the reciprocating movement of the shaft sleeve 2.
[0035] Preferably, an annular extension 22 is arranged on the inner wall of the shaft sleeve 2 around the axis of the shaft sleeve 2. The extension 22 surrounds the limit hole 221. That is, the hole diameter of the limit hole 221 is smaller than the diameter of the second segment 13. The outer contour of the first segment 11 can be slightly smaller, so that the first segment 11 does not interfere with the shaft sleeve 2 sleeved on the rotating shaft 1, and the flat position 111 can be clamped with the limit hole 221.
[0036] More preferably, the connecting section 12 is arranged between the first section 11 and the second section 13, and the diameter of the connecting section 12 is smaller than the hole diameter of the limiting hole 221. The sleeve 2 is sleeved on the rotating shaft 1, and when the flat portion 111 is not clamped in the limiting hole 221, the extension 22 is located at the connecting section 12. At this time, the connecting section 12 does not interfere with the movement of the sleeve 2.
[0037] Please refer to Figure 1 and Figure 2 The first limiting rail 131 includes two wave crests 132 and two wave troughs 133, and the two wave crests 132 and the two wave troughs 133 are arranged alternately. When the second limiting rail 21 slides along the first limiting rail 131 for one turn, the sleeve 2 reciprocates along the axial direction of the rotating shaft 1 twice. Limiting the number of reciprocations of the sleeve 2 to twice avoids that the frequency of reciprocation of the sleeve 2 is too high, which affects the stability of the operation of the floating knife group.
[0038] Preferably, the second limiting rail 21 is arranged on the inner wall of the sleeve 2. That is, when the first limiting rail 131 contacts the second limiting rail 21, the sleeve 2 is sleeved on the first limiting rail 131. The inner wall of the sleeve 2 can limit the position between the sleeve 2 and the rotating shaft 1, further improve the position accuracy between the rotating shaft 1 and the sleeve 2, and the stability when the floating knife group rotates.
[0039] Please refer to Figure 1 and Figure 2 The upper knife assembly 3 includes a plurality of blades. When the upper knife assembly 3 includes one blade, the blade is arranged at an acute angle with the axis of the rotating shaft 1. When the upper knife assembly 3 includes at least two blades, all the blades are in the same plane, and the blades are uniformly arranged circumferentially around the rotating shaft 1, and the plane formed by all the blades is arranged at an acute angle with the axis of the rotating shaft 1. All the blades are in the same plane, which can fully expand the cutting range of the upper knife assembly 3 in the vertical direction. And the circumferential uniform arrangement of the blades helps to improve the structural stability of the floating knife group and reduce vibration.
[0040] Preferably, the lower knife assembly 4 is further included, and the lower knife assembly 4 is arranged on the rotating shaft 1. The upper knife assembly 3 and the lower knife assembly 4 work simultaneously, increase the contact area between the blades and the food materials, so that the food materials are cut at a higher frequency, and the chopping efficiency of the food materials is improved.
[0041] The specific working process of the embodiment is as follows:
[0042] In the stationary state, the shaft sleeve 2 is located at the low position on the rotating shaft 1 under the influence of gravity. When the floating knife group is working, the rotating shaft 1 is driven to rotate, and the rotating shaft 1 drives the shaft sleeve 2 to rotate in the same direction through friction. Under the influence of resistance, the rotating speed of the shaft sleeve 2 will be lower than that of the rotating shaft 1, that is, the second limiting rail 21 will slide along the first limiting rail 131, that is, the shaft sleeve 2 will move up and down along the axial direction of the rotating shaft 1. At this time, the upper knife assembly 3 rotates while moving up and down. When the second limiting rail 21 moves to the wave crest 132 of the first limiting rail 131, the flat position 111 is clamped in the limiting hole 221. At this time, the flat position 111 and the limiting hole 221 cooperate to transmit torque, and the rotating shaft 1 and the shaft sleeve 2 rotate synchronously, and the upper knife assembly 3 rotates synchronously with the rotating speed of the rotating shaft 1. Stop driving the rotating shaft 1 to rotate, and under the action of gravity, the shaft sleeve 2 moves downward along the rotating shaft 1. Repeat the above-mentioned driving the rotating shaft 1 to rotate, and pause the driving the rotating shaft 1 to rotate, so as to realize the reciprocating movement of the upper knife assembly 3 along the rotating shaft 1.
[0043] Embodiment two
[0044] Figure 3 The vertical section structure schematic diagram of the food processor in the embodiment two of the utility model is shown. Figure 3 Based on the embodiment one, the embodiment two discloses a kind of food processor, and the food processor includes host computer 5, container 6 and floating knife group. Host computer 5 is connected rotating shaft 1. Rotating shaft 1 extends into container 6. By reciprocating movement when rotating shaft 1 rotates, and obliquely arranged upper knife assembly 3, when rotating shaft 1 rotates, it can be widely shredded in the food material in container 6, guarantee the efficiency of food material shredding. In addition, the side wall of container 6 is obliquely arranged. The caliber of one end of container 6 close to host computer 5 is less than the caliber of one end of container 6 away from host computer 5. So that when food processor works, the food material that is shredded and agitated is more easily rolled to the center position of cup body, facilitate upper knife assembly 3 and lower knife assembly 4 shred food material.
