Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances technology, and in particular to a food processing device. Background Technology

[0002] Among existing kitchen appliances, food processing devices, capable of slicing and shredding food, are gradually gaining popularity among users. These devices consist of a base and a cover. The base has a basket for holding the food, and the cover holds the food within the basket. To improve stability during food processing, the base and cover are connected by a rotating shaft assembly, allowing the operator to open and close the cover with one hand while ensuring it stays in place, thus increasing operational efficiency.

[0003] In existing technologies, a torsion spring is typically required to drive the lid to rotate in the opening direction, allowing users to open the lid and place food into the basket. Furthermore, to facilitate disassembly and reassembly of the base and lid, the pivot assembly connecting them is often a telescopic structure. However, the torsion spring is fitted onto the pivot assembly, with both ends abutting against the base and lid respectively. This structure is complex. During installation, the pivot assembly needs to be pressed to retract into the base, and when installing the lid onto the base, one end of the torsion spring needs to be pressed to insert it between the lid and the base. This makes installation inconvenient and inefficient. Utility Model Content

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1-3 As shown, this embodiment provides a food processing device, which includes a base 1 and a cover plate 3. A basket 12 is provided on the base 1. The basket 12 is used to hold food to be processed, such as vegetables or meat. The cover plate 3 is rotatably connected to the base 1. When the food is cut (such as shredded or sliced), the cover plate 3 can close to the base 1 to press the food in the basket 12 tightly.

[0043] Understandably, the food processing device also includes a blade 33, which uses the relative movement between the blade 33 and the food to be processed to perform the cutting operation on the food.

[0044] In some embodiments, the blade 33 is disposed in the base 1 and connected to the drive motor 5 through a crank-slider mechanism. The bottom of the basket 12 is provided with a processing hole, and the reciprocating motion of the blade 33 is used to cut vegetables or meat in the basket 12.

[0045] like Figures 1-3As shown, in this embodiment, the blade 33 is fixedly connected to the cover plate 3, and the basket 12 is connected to the drive motor 5 through a crank-slider mechanism. The reciprocating motion of the basket 12 enables the blade 33 to cut the vegetables and meat inside the basket 12. In addition, to allow the blade 33 to enter the basket 12, clearance grooves are provided on both the front and rear side walls of the basket 12 along the direction of movement of the basket 12, allowing the blade 33 to enter the clearance grooves to cut the food inside the basket 12.

[0046] like Figures 3-5 As shown, in order to facilitate the assembly and disassembly of the cover plate 3 and the base 1, the food processing device also includes a rotating shaft assembly 2. The base 1 is provided with a connecting platform 11. The rotating shaft assembly 2 includes a main shaft 21 and a telescopic shaft 22. The end of the main shaft 21 is provided with a telescopic groove 211. The telescopic shaft 22 is slidably disposed in the telescopic groove 211 along the axial direction of the main shaft 21. The main shaft 21 is disposed in the connecting platform 11. The telescopic shaft 22 can extend or retract into the connecting platform 11. The cover plate 3 is provided with a connecting hole 32. The telescopic shaft 22 can pass through the connecting hole 32 to make the cover plate 3 and the base 1 rotatably connected.

[0047] In this food processing device, the base 1 and the cover plate 3 are connected by a rotating shaft assembly 2. The main shaft 21 of the rotating shaft assembly 2 is set inside the connecting platform 11. When assembling the base 1 and the cover plate 3, the telescopic shaft 22 is first retracted into the connecting platform 11. When the cover plate 3 is in the appropriate position, the telescopic shaft 22 is extended out of the connecting platform 11 and inserted into the connecting hole 32 to complete the installation, which improves the installation efficiency.

[0048] In this embodiment, the food processing device further includes a first elastic element 4, which is configured to drive the cover 3 to open. On the one hand, it can automatically rotate the cover 3 away from the base 1 when the user wants to open the cover 3; on the other hand, it can also make the cover 3 stably stop at a specific angle, which is convenient for putting food into the basket 12.

[0049] In this embodiment, the food processing device can be a cutting and slicing machine or a cooking robot. Both cutting and slicing machines and cooking robots can process specific ingredients. Cutting and slicing machines can quickly complete operations such as slicing, shredding, and dicing ingredients, and the thickness / shape is uniform, avoiding human error and ensuring the appearance of the dishes and the consistency of cooking. Cooking robots can also be set with cutting and slicing functions, which can not only realize the physical processing of ingredients, but also accurately control the heat, seasoning, and time, ensuring that the taste and cooking degree of the dishes are consistent, and the serving efficiency is high, which can alleviate peak pressure.

[0050] Since the rotating shaft assembly 2 is a split mechanism, in order to ensure that the driving force of the first elastic element 4 on the cover plate 3 is relatively stable during the opening process, the first elastic element 4 is usually placed between the base 1 and the cover plate 3. That is, the first elastic element 4 simultaneously abuts against the base 1 and the cover plate 3 to generate an elastic force on the cover plate 3 to drive the cover plate 3 to rotate. However, this structure inevitably increases the structural complexity of the base 1 and the cover plate 3, and when installing the cover plate 3 and the base 1, the operator needs to press the first elastic element 4 to insert the first elastic element 4 between the cover plate 3 and the base 1, resulting in low installation efficiency.

[0051] To solve the above problems, in this food processing device, the rotating shaft assembly 2 and the cover plate 3 rotate synchronously, and the first elastic element 4 is set in the connecting platform 11. The first elastic element 4 is configured to drive the cover plate 3 to open through the rotating shaft assembly 2.

[0052] Since the first elastic element 4 is located inside the connecting platform 11 and can drive the cover plate 3 to open via the rotating shaft assembly 2, during assembly, the rotating shaft assembly 2 and the first elastic element 4 can be assembled into the connecting platform 11 before installing the cover plate 3. Then, only the telescopic shaft 22 needs to be pressed to assemble the cover plate 3 and the base 1 together, thereby avoiding the influence of the first elastic element 4 on the installation of the cover plate 3.

[0053] The first elastic element 4 of the food processing device is located between the base 1 and the rotating shaft assembly 2, which avoids the influence of the first elastic element 4 on the installation of the cover plate 3, simplifies the structure and improves the installation efficiency.

[0054] Specifically, a first synchronization structure is provided between the main shaft 21 and the telescopic shaft 22, which is configured to make the main shaft 21 and the telescopic shaft 22 rotate synchronously. A second synchronization structure is provided between the telescopic shaft 22 and the cover plate 3, which is configured to make the telescopic shaft 22 and the cover plate 3 rotate synchronously. Through the first and second synchronization structures, the rotation of the main shaft 21 can be synchronously transmitted to the cover plate 3, which means that the first elastic element 4 can drive the main shaft 21 to rotate in order to drive the cover plate 3 to rotate.

[0055] In some embodiments, one of the main shaft 21 and the telescopic shaft 22 is provided with a protrusion, and the other is provided with a sliding groove. The protrusion and the sliding groove are slidably matched to form a first synchronization structure. One of the telescopic shaft 22 and the cover plate 3 is provided with a protrusion, and the other is provided with a sliding groove. The protrusion and the sliding groove are slidably matched to form a second synchronization structure, thereby completing the relative locking of the main shaft 21 and the telescopic shaft 22, as well as the telescopic shaft 22 and the cover plate 3 in the circumferential direction.

[0056] like Figure 2 , Figure 6 and Figure 7As shown, the first synchronization structure includes a first abutment surface 212 disposed on the inner wall of the telescopic groove 211 and a second abutment surface 221 disposed on the outer periphery of the telescopic shaft 22. The first abutment surface 212 and the second abutment surface 221 slide against each other to lock the main shaft 21 and the telescopic shaft 22 circumferentially. Since the first abutment surface 212 and the second abutment surface 221 slide against each other, when the main shaft 21 rotates, torque is transmitted to the telescopic shaft 22 through the first abutment surface 212 and the second abutment surface 221, thereby driving the telescopic shaft 22 to rotate, ensuring that the main shaft 21 and the telescopic shaft 22 rotate synchronously, that is, locking the main shaft 21 and the telescopic shaft 22 circumferentially.

[0057] Similarly, the second synchronization structure includes a third abutment surface 222 disposed on the outer periphery of the telescopic shaft 22 and a fourth abutment surface 321 disposed on the inner side of the connecting hole 32. The third abutment surface 222 and the fourth abutment surface 321 slide against each other to lock the telescopic shaft 22 and the cover plate 3 circumferentially. The third abutment surface 222 and the fourth abutment surface 321 can lock the telescopic shaft 22 and the cover plate 3 circumferentially, ensuring that the telescopic shaft 22 and the cover plate 3 rotate synchronously.

[0058] In this embodiment, the rotating shaft assembly 2 includes two telescopic shafts 22. The main shaft 21 has telescopic grooves 211 at both ends along the axial direction. The cover plate 3 includes two connecting arms 31 spaced apart. Each connecting arm 31 has a connecting hole 32. Each telescopic shaft 22 is slidably disposed in the telescopic groove 211 at the corresponding end and passes through the corresponding connecting hole 32.

[0059] The rotating shaft assembly 2 extends telescopic shafts 22 on both sides of the connecting platform 11. When the cover plate 3 rotates relative to the base 1, it can make the cover plate 3 bear the force evenly, ensuring that the rotation axis of the cover plate 3 coincides with the rotation axis of the rotating shaft assembly 2, and avoiding the cover plate 3 from tilting during rotation, which would affect the user experience.

[0060] like Figures 4-7 As shown, the rotating shaft assembly 2 also includes a second elastic element 23, which is located between the telescopic shaft 22 and the main shaft 21. The second elastic element 23 is configured to drive the telescopic shaft 22 to move along the direction of extending out of the telescopic groove 211. That is, the second elastic element 23 will drive the telescopic shaft 22 to extend out of the connecting platform 11, ensuring that after the cover plate 3 is installed on the base 1 and the telescopic shaft 22 passes through the connecting hole 32, the telescopic shaft 22 will not retract without cause, thus preventing the cover plate 3 from separating from the base 1, thereby improving the reliability of the food processing device.

[0061] Furthermore, a first limiting protrusion 223 is provided on the outer periphery of the telescopic shaft 22. The first limiting protrusion 223 can abut against the inner side of the connecting platform 11 to limit the telescopic shaft 22. On the one hand, the limiting protrusion can ensure that the telescopic shaft 22 is limited by the connecting platform 11 to a stable state when the cover plate 3 is not assembled to the base 1, so that the operator does not need to press the telescopic shaft 22 at all times to prevent the telescopic shaft 22 from being popped out by the second elastic element 23. On the other hand, after the cover plate 3 is assembled to the base 1, the limiting protrusion can improve the stability of the telescopic shaft 22 by abutting against the inner wall of the connecting platform 11 through the first limiting protrusion 223, so as to avoid the telescopic shaft 22 from shifting and causing the axis of the telescopic shaft 22 to deviate from the main shaft 21.

[0062] Preferably, the second elastic element 23 is a spring, which is sleeved on the telescopic shaft 22, with one end of the spring abutting against the end face of the main shaft 21 and the other end abutting against the first limiting protrusion 223. Using the first limiting protrusion 223 to connect the spring can reduce the complexity of the structure of the telescopic shaft 22 and facilitate processing.

[0063] Understandably, since the second elastic element 23 simultaneously abuts against both the main shaft 21 and the telescopic shaft 22, after the telescopic shaft 22 is limited by the inner wall of the connecting platform 11 via the first limiting protrusion 223, the second elastic element 23 will also drive the main shaft 21 to move. For example... Figures 4-6 As shown, in order to ensure the stability of the spindle 21 within the connecting platform 11, a second limiting protrusion 213 is provided on the outer periphery of the spindle 21, and a limiting part 115 is provided inside the connecting platform 11. The limiting part 115 is located on the side of the second limiting protrusion 213 away from the second elastic member 23, and the second limiting protrusion 213 can abut against the limiting part 115 to limit the spindle 21.

[0064] The first limiting protrusion 223 and the second limiting protrusion 213 restrict the maximum distance that the telescopic shaft 22 can slide out of the telescopic groove 211, thereby ensuring that the second elastic element 23 is always in a compressed state, thus ensuring the stability of the rotating shaft assembly 2. It is worth noting that the rotating shaft assembly 2 has a symmetrical structure, with two second limiting protrusions 213 protruding from the main shaft 21. The two second limiting protrusions 213 can restrict the axial movement of the main shaft 21 from two opposite directions, which ensures the stability of the main shaft 21 within the connecting platform 11 and the stability of the rotating shaft assembly 2.

[0065] Furthermore, the main shaft 21 also includes an abutment portion 214, which is disposed on the second limiting protrusion 213. The first elastic element 4 is a torsion spring, with one end of the torsion spring abutting against the base 1 and the other end of the torsion spring abutting against the abutment portion 214. It can be understood that by disposing the abutment portion 214 on the second limiting protrusion 213 and allowing the torsion spring to apply an elastic force to the main shaft 21 through the abutment portion 214, the distance between the position of application of the elastic force and the axis of the main shaft 21 can be increased, that is, the lever arm is increased, so that the torsion spring can generate a larger torque on the main shaft 21, making it easier for the torsion spring to overcome the gravity of the cover plate 3 and drive the cover plate 3 to rotate.

[0066] Understandably, because the abutment portion 214 is located on the second limiting protrusion 213, the rotation radius of the abutment portion 214 is relatively large when the main shaft 21 rotates. Figure 1 As shown, in order to reduce the space occupied by the connecting platform 11, the connecting platform 11 is provided with a clearance hole 113. When the cover plate 3 is opened relative to the base 1, the abutment part 214 passes through the clearance hole 113. By using the clearance hole 113 to avoid the abutment part 214, the volume of the connecting platform 11 can be reduced to the greatest extent, thereby reducing the volume of the entire food processing device.

[0067] In this embodiment, the connecting platform 11 includes a mounting base 112 connected to the base 1 and an upper cover 111 fastened to the mounting base 112. The rotating shaft assembly 2 is mounted on the mounting base 112, and the upper cover 111 fastens the rotating shaft assembly 2 to the mounting base 112 to ensure the stability of the rotating shaft assembly 2, so that the rotating shaft assembly 2 can only rotate.

[0068] Specifically, the limiting part 115 is provided in the mounting base 112 to axially limit the spindle 21, and the clearance hole 113 is provided in the upper cover 111. Therefore, when the cover plate 3 is fastened to the base 1, the abutting part 214 is located above the spindle 21 to reduce the height of the mounting base 112.

[0069] like Figures 4-6 As shown, in order to ensure that the cover plate 3 can stop in a stable position after opening, the side wall of the main shaft 21 is provided with a limiting boss 216, and the connecting platform 11 is provided with a limiting platform 114. When the cover plate 3 is opened relative to the base 1, the limiting boss 216 can abut against the limiting platform 114 to limit the maximum opening angle between the cover plate 3 and the base 1.

[0070] It is worth noting that when the limiting boss 216 abuts against the limiting platform 114, the cover plate 3 is at its maximum opening angle. At this time, the abutting part 214 passes through the clearance hole 113, and the abutting part 214 does not contact the inner wall of the clearance hole 113, so as to avoid the abutting part 214 and the upper cover 111 from being pressed with marks due to the elastic force of the first elastic member 4, which would affect the appearance.

[0071] To ensure that the torsion spring and the abutment part 214 do not separate due to relative sliding when they abut, the abutment part 214 is provided with an abutment groove 215, and one end of the torsion spring is embedded in the abutment groove 215.

[0072] In this embodiment, the food processing device also includes a latch, which is set on the base 1. When the cover plate 3 is fastened to the base 1, the latch can lock the cover plate 3 to the base 1, thereby ensuring that the cover plate 3 will not open and cause injury to the user when the food is being cut, thus avoiding potential safety hazards.

[0073] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
