[0054] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] Example 1

[0056] This embodiment provides a specific implementation of a cutting assembly, such as Figures 1 to 5 As shown, it includes: a shaft rod 1, a knife groove structure 2, a blade 4, an adjustment structure, and a locking structure.

[0057] The shaft 1 is suitable for being connected to a motor and is driven by the motor to rotate.

[0058] There is at least one knife groove structure 2 fixedly disposed on the shaft 1, and a knife groove 3 is formed on the knife groove structure 2. In the present embodiment, there are multiple knife groove structures 2, specifically three, and the multiple knife groove structures 2 are radially distributed on the outer peripheral wall of the shaft 1, and each knife groove structure 2 forms an angle with the axial direction of the shaft 1.

[0059] The blade 4 is retractably arranged in the knife groove 3, and at least a part of the blade 4 is adapted to extend out of the knife groove 3, and the extension direction of the blade 4 is at an angle to the axial direction of the shaft 1. In this embodiment, the blade 4 is provided with a blade, and the blade is arranged in the length direction of the blade 4, so the extension direction of the blade 4 is consistent with the extension direction of the blade. Therefore, when the blade 4 is extended, the length of the blade becomes longer, and the blade can cut the food by rotating with the shaft 1.

[0060] The blade 4 is adjusted to extend out of the blade groove 3 by the adjusting structure, and its extended position is locked by the locking structure, so that the extended length of the blade 4 of the cutting assembly can be ensured to be constant during operation, thereby ensuring safe use.

[0061] In this embodiment, one end of the adjustment structure is connected to the blade 4, and the other end is connected to the shaft 1. Specifically, the adjustment structure includes a clip 5 and an adjustment rod 6, wherein the clip 5 is adjustable and sleeved outside the shaft 1; the adjustment rod 6 is connected to the blade 4 at one end and connected to the clip 5 at the other end. The length of the adjustment rod 6 in this embodiment is not adjustable. In other alternative embodiments, the adjustment rod 6 can be a telescopic rod, and the extension length of the blade 4 can be adjusted by adjusting the length of the telescopic rod.

[0062] Specifically, the blade groove structure 2 has a top opening, a first hanging ring 41 is provided on the top surface of the blade 4, the first hanging ring 41 extends out of the top opening, a second hanging ring 51 is provided on the outer peripheral surface of the clip 5, and hooks 62 are provided at both ends of the adjusting rod 6, and the two ends of the adjusting rod 6 are respectively connected to the first hanging ring 41 and the second hanging ring 51.

[0063] At least one first sharp edge 61 is formed on the outer wall of the adjusting rod 6, and at least part of the first sharp edge 61 is oriented in the same direction as the rotation direction of the shaft 1. During operation of the cutting assembly, the adjusting rod 6 can also perform cutting work, thereby improving cutting efficiency.

[0064] Preferably, the first sharp edge 61 is parallel to the length extension direction of the adjusting rod 6, which is convenient for processing and has high cutting efficiency.

[0065] In this embodiment, the locking structure includes an external thread structure provided on the outer wall of the shaft 1, and a first nut 7 and a second nut 8, wherein the first nut 7 is provided at one end of the clip 5 close to the knife groove structure 2 and is threadedly connected with the external thread structure, and the second nut 8 is provided at one end of the clip 5 away from the knife groove structure 2, and the first nut 7 and the second nut 8 clamp the clip 5 therein. The first nut 7 and the second nut 8 can ensure that the position of the clip 5 does not change, thereby ensuring the locking effect of the extended length of the blade 4, and it is safer to use.

[0066] A plurality of second sharp edges 21 are formed outside the knife groove structure 2, and at least part of the second sharp edges 21 are oriented in the same direction as the rotation direction of the shaft 1. When the cutting assembly is working, the knife groove structure 2 can also perform cutting work, thereby improving the cutting efficiency. In addition, since the knife groove structure 2 and the shaft 1 are axially angled with each other, the knife groove structure 2 itself is equivalent to forming a part of the blade 4, extending the length of the blade 4. When the juicer has a larger caliber, the cutting assembly can also be applied.

[0067] Preferably, the second sharp edge 21 is parallel to the extension direction of the blade 4. This arrangement facilitates processing of the second sharp edge 21 on the knife groove structure 2.

[0068] A smooth convex surface 22 is formed on the peripheral wall of the end of the knife groove 3. During the installation of the cutting assembly, the hand can hold the convex surface 22 to avoid being cut. Or when the knife groove structure 2 falls, the convex surface 22 can also prevent the knife groove structure 2 from scratching the user.

[0069] During installation, firstly, the two ends of the adjusting rod 6 are connected to the first hanging ring 41 on the blade 4 and the second hanging ring 51 on the outer surface of the clip 5 through the hook 62, the first nut 7 is screwed on the shaft 1, and the clip 5 is sleeved outside the shaft 1. By adjusting the position of the first nut 7, the three blades 4 are all slid into the knife groove 3, and the positions of the first nut 7 and the clip 5 are adjusted again to adjust the extension length of the blade 4 to the required length. At this time, the second nut 8 is screwed on the shaft 1, and the second nut 8 and the first nut 7 clamp the clip 5. If it is necessary to adjust the extension length of the blade 4, the positions of the first nut 7 and the second nut 8 can be adjusted. During use, the shaft 1 rotates under the drive of the motor, and the blade 4, the second sharp edge 21 on the knife groove structure 2, and the first sharp edge 61 on the adjusting rod 6 cut the food at the same time. During transportation, the positions of the clip 5, the first nut 7, and the second nut 8 can be adjusted to make the blade 4 completely retracted into the knife groove 3, so as to avoid the blade 4 from hurting people, which is safer.

[0070] As a first replaceable embodiment of the above-mentioned embodiment, the extension length of the blade 4 is manually adjusted. When the extension length of the blade 4 needs to be adjusted, the locking force is manually overcome to push the blade 4 out. In this embodiment, there is no need to set an adjustment structure, and the interference fit connection between the blade 4 and the knife groove 3 locks the extension position of the blade 4.

[0071] As a second alternative embodiment of the above embodiment, the locking structure is an interference fit connection between the clip 5 and the shaft rod 1 .

[0072] As a third replaceable embodiment of the above embodiment, the locking structure only includes the first nut 7. When the locking assembly is in operation, the centrifugal force generated will cause the clip 5 to move downward. Therefore, the setting of the first nut 7 can prevent the clip 5 from moving downward. In the absence of other external forces, the clip 5 will not move up automatically. Therefore, the second nut 8 may not be set.

[0073] Example 2

[0074] This embodiment provides a food processing device, including the cutting assembly provided in the above embodiment. The food processing device can be a juicer, a food processor, a wall breaking machine, etc.

[0075] When the blade 4 of the food processing device is lost or damaged, it is not necessary to use a blade 4 of a special size, so the device is easy to use.

[0076] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
