[0025] This application provides a handheld vegetable cutter that is easy to assemble and disassemble, which solves the technical problem that the installation process of the existing vegetable cutter drive device is cumbersome and significantly increases the difficulty of maintenance, ultimately leading to an increase in the overall processing cost.

[0026] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figures 1 to 8 This application provides a handheld vegetable cutter that is easy to assemble and disassemble, including a housing 10, a drive device 20, a connecting cover plate 30, and a cutting cylinder 40. One end of the housing 10 is a mounting port 11, and the connecting cover plate 30 is locked and fixed to the mounting port 11 to close the inner cavity of the housing 10. The drive device 20 has a plurality of fixing buckles 21 extending from its outer periphery. The connecting cover plate 30 has a fixing post 31 extending from its inner side that matches the fixing buckles 21. The fixing buckles 21 are sleeved on the fixing post 31 and fastened by threaded connection. The connecting cover plate 30 has a snap-fit ​​ring 32 extending from its outer side. The snap-fit ​​ring 32 is detachably screwed onto the snap-fit ​​groove 41 provided on the cutting cylinder 40 to lock the cutting cylinder 40.

[0028] Specifically, the interior of the housing 10 is a cavity, with a mounting port 11 on one side. The shape of the connecting cover plate 30 matches the mounting port 11. Multiple threaded posts are provided near the mounting port 11 on the housing 10. The connecting cover plate 30 is locked and fixed to the threaded posts via a threaded connection, thereby closing the mounting port 11 and forming a cavity within the housing 10 to accommodate the drive device 20. Multiple fixing buckles 21 extend from the outer periphery of the drive device 20. In this embodiment, the fixing buckles 21 are triangularly distributed around the outer periphery of the drive device 20, ensuring installation stability while simplifying the assembly and disassembly process. After the fixing buckles 21 are sleeved onto the fixing posts 31, they are fastened via threaded connections, allowing the drive device 20 to... Fixed to the connecting cover plate 30, the connecting cover plate 30 and the drive device 20 form an assembly unit during disassembly and assembly, which significantly simplifies the disassembly and maintenance process and effectively reduces processing time and cost. A snap-fit ​​ring 32 extends from the side of the connecting cover plate 30 that connects to the cutting tube 40. The outer circumference of the snap-fit ​​ring 32 has spirally distributed and spaced protrusions. The cutting tube 40 is recessed into its inner cavity to form a snap-fit ​​groove 41. The inner wall of the snap-fit ​​groove 41 is threaded. The snap-fit ​​ring 32 and the inner wall of the snap-fit ​​groove 41 are rotated and locked together, so that the cutting tube 40 can be quickly connected and is easy to disassemble and assemble. This makes the disassembly and assembly process of the entire vegetable cutter simple and convenient for users.

[0029] Furthermore, the driving device 20 includes a reduction gear seat 22 and a drive motor 23. The reduction gear seat 22 has a retaining buckle 21 extending from its outer periphery. One end of the reduction gear seat 22 abuts against the connecting cover plate 30, and the other end extends into a limiting wall 221. The drive motor 23 is installed inside the limiting wall 221. The reduction gear seat 22 and the drive motor 23 combine to form an integral driving device 20. The retaining buckle 21 extending from the outer periphery of the reduction gear seat 22 is fastened and fixed to the fixing post 31, allowing the reduction gear seat 22 to abut against the connecting cover plate 30, preventing vibration and displacement during motor operation. The other end of the reduction gear seat 22 extends into a limiting wall 221 to limit the position of the drive motor 23. The drive motor 23 is fixed to the directly fixed reduction gear seat 22, thus the entire driving device 20 can quickly form a fixed connection with the connecting cover plate 30, facilitating assembly and disassembly.

[0030] See Figures 4 to 6 The reduction gear 22 includes a first connecting sleeve 222, a connecting plate 223, and a second connecting sleeve 224 connected in sequence and locked in place by a threaded connection; the connecting plate 223 has a fixing buckle 21 extending from its outer periphery; a reduction gear 24 is installed in the inner cavity of the first connecting sleeve 222 and the second connecting sleeve 224. The second connecting sleeve 224 has a limiting wall 221 extending from it, and the drive motor 23 is fixed to the second connecting sleeve 224 by a threaded connection. The connecting plate 223 is located in the middle of the first connecting sleeve 222 and the second connecting sleeve 224, and the three are fastened together by threads. The connecting plate 223 separates the inner cavity of the reduction seat 22, so that the inner cavities of the first connecting sleeve 222 and the second connecting sleeve 224 respectively form the chambers for installing the reduction gear 24, which facilitates the assembly of the reduction gear 24. The fixing buckle 21 extends outward from the outer periphery of the connecting plate 223 and is fixed by sleeve with the fixing post 31, so that the reduction seat 22 as a whole can be stably connected to the connecting cover plate 30. The second connecting sleeve 224 is located near the middle of the housing 10. By extending the limiting wall 221, it forms the installation position of the drive motor 23, and the drive connection is fixed to the second connecting sleeve 224 by threads, thereby forming a drive device 20 with the drive motor 23 and the reduction seat 22 as a whole, which drives the vegetable cutter to perform the vegetable cutting operation. The overall structure is simple and reasonable, simplifying the manufacturing process. The limiting wall 221 has multiple supporting ribs 2211 extending vertically on its inner side, and the supporting ribs 2211 are inclined at the top of the limiting wall 221. The limiting wall 221 forms an annular groove, and multiple supporting ribs 2211 are arranged vertically at intervals on its inner wall. The top of the supporting ribs 2211 is inclined at the upper end of the limiting wall 221. When the drive motor 23 is installed, it has a guiding state and can be quickly inserted into the limiting wall 221 for quick positioning and installation. The supporting ribs 2211 also strengthen the structural strength of the limiting wall 221, ensuring that the limiting drive motor 23 is not easily deviated due to vibration when it is limited.

[0031] Furthermore, an elastic sleeve 50 is fitted around the outer periphery of the fixing post 31, and the fixing buckle 21 is snapped onto the outer side of the elastic sleeve 50; a limiting rib 311 extends from the outer periphery of the fixing post 31, and one end of the elastic sleeve 50 abuts against the top of the limiting rib 311. The elastic sleeve 50 is I-shaped, and the groove in the middle matches the hole of the fixing buckle 21, so that the hole of the fixing buckle 21 is embedded in the middle of the elastic sleeve 50. Through the connection between the elastic sleeve 50 and the fixing post 31, the driving device 20 is provided with radial buffering during operation, absorbing the vibration of the driving device 20. The limiting rib 311 on the outer periphery of the fixing post 31 strengthens the structural strength and forms an abutment wall of the elastic sleeve 50 at the top, ensuring the stability of the position of the elastic sleeve 50. At the same time, the inner wall of the fixing post 31 has threads, and the elastic sleeve 50 and the fixing buckle 21 are fastened by the threaded connection, ensuring a stable connection while absorbing shock.

[0032] See further Figure 7 A latch 33 is installed on the outer side of the connecting cover plate 30, and a latch groove 43 extends from the outer wall of the feeding area 42 of the cutting tube 40. After the cutting tube 40 is engaged with the connecting cover plate 30, it is engaged with the latch 33 through the latch groove 43 to lock the cutting tube 40. A latch 33 is fixed to the outer wall of the connecting cover plate 30 near the top. The upper part of the cutting tube 40 is the feeding area 42, and its outer wall is provided with a corresponding latch groove 43. In this embodiment, the outer wall of the feeding area 42 of the cutting tube 40 has an extension wall 44 that matches the shape of the shell 10, so that the appearance of the cutting tube 40 and the shell 10 is continuous when connected. The latch groove 43 is provided in the extension wall 44. The square wall formed by the extension wall 44 is provided with a groove corresponding to the latch 33 at the top of the square wall. During the installation of the cutting tube 40, after the snap ring 32 and the snap groove 41 are screwed into place, the latch 33 is engaged in the latch groove 43, thereby forming a double-stage locking mechanism to prevent the cutting tube 40 from accidentally disengaging due to the resistance of the food, and improve the safety of operation.

[0033] Furthermore, the front side of the driving device 20 has a driving shaft 25, which is engaged with a transmission member 60. The transmission member 60 engages with the blade cylinder 45 inside the cutting cylinder 40 to drive the blade cylinder 45 to rotate. The blade cylinder 45 has a transmission groove 451 on the side near the driving device 20. A first transmission rib 4511 extends spirally from the inner side of the transmission groove 451. The first transmission rib 4511 is L-shaped. A second transmission rib 61 extends from the outer periphery of the transmission member 60 and cooperates with the first transmission rib 4511. The first transmission rib 4511 and the second transmission rib 61 are interlocked so that the driving device 20 drives the blade cylinder 45 to rotate. The drive shaft 25 of the drive device 20 is fixed with a square block, which engages with the transmission component 60. The knife cylinder 45 is located in the inner cavity of the cutting cylinder 40, and the side of the knife cylinder 45 near the drive device 20 is recessed to form a transmission groove 451. The middle part of the engagement groove 41 is hollow, so that the transmission component 60 passes through the engagement groove 41 and engages with the transmission groove 451. The first transmission rib 4511 formed by the inner wall of the transmission groove 451 is L-shaped and matches the shape of the second transmission rib 61 extending from the outer periphery of the transmission component 60. The first transmission rib 4511 and the second transmission rib 61 engage to quickly install and fix the knife cylinder 45. By generating an axial locking force, the axial movement of the knife cylinder 45 during operation is prevented. The indirect engagement between the transmission component 60 and the knife cylinder 45 allows the knife cylinder 45 to be quickly replaced independently of the drive device 20, which is convenient for users.
