[0040] The technical solutions of the present application will be further illustrated below in conjunction with the accompanying drawings and through specific embodiments.

[0041] The present embodiment provides a food material processing device, as shown in Figure 1 and Figure 2 , which comprises a main body 1, a transmission assembly, and a cutting assembly 13, the main body 1 comprises a base 11 and a cover plate 12, the transmission assembly is arranged in the base 11, the cutting assembly 13 comprises a basket 131 and a cutter 132, the basket 131 is used to contain food materials to be processed, such as vegetables or meat, and at least one of the basket 131 and the cutter 132 is in transmission connection with an input shaft 14, when the input shaft 14 rotates, the basket 131 and the cutter 132 move relatively to enable the cutter 132 to perform a cutting operation (such as shredding or slicing) on the food materials in the basket 131.

[0042] In some embodiments, the cutter 132 is arranged in the base 11 and connected with the input shaft 14 through a crank slider mechanism, and the bottom of the basket 131 is provided with a processing hole, and the vegetables or meat in the basket 131 are cut through the reciprocating movement of the cutter 132.

[0043] In the present embodiment, the cutter 132 is fixedly connected with the cover plate 12, and the basket 131 is connected with the input shaft 14 through a crank slider mechanism, and the cutter 132 can perform a cutting operation on the vegetables and meat in the basket 131 through the reciprocating movement of the basket 131. In addition, in order to enable the cutter 132 to enter the basket 131, the front and rear side walls of the basket 131 are each provided with a avoiding slot in the moving direction of the basket 131, and the cutter 132 can enter the avoiding slot to cut the food materials in the basket 131.

[0044] As shown in Figure 1 and Figure 3As shown, to achieve automatic cutting of ingredients, the food processing device further includes a drive assembly 3, which includes a housing 31 and a drive motor. The drive motor is disposed within the housing 31, and an output shaft 34 of the drive motor is connected to an input shaft 14 to drive the relative movement of the basket 131 and the cutter 132. However, when a user opens the cover 12 and adds ingredients to the basket 131, there is a risk that the drive assembly 3 may be accidentally activated, causing the cutter 132 to injure the user, posing a high risk and a safety hazard.

[0045] like Figures 1 to 5 As shown, to address the aforementioned issues, the food processing device further includes a safety linkage assembly 2 comprising a linked trigger 21 and an actuator 22. The trigger 21 is protruding from the base 11, and the drive assembly 3 is provided with a safety switch 33. When the cover 12 is engaged with the base 11, pressing the trigger 21 causes the actuator 22 to trigger the safety switch 33, thereby energizing the drive motor and activating the drive motor, enabling the cutter 132 to cut the food in the basket 131.

[0046] That is to say, when the cover 12 is opened, the trigger 21 will not be pressed, and the actuator 22 will not trigger the safety switch 33. At this time, the circuit of the drive motor is not conducted, so that the user cannot accidentally start the drive motor when the cover 12 is open, thereby avoiding risks and ensuring the safety of the user.

[0047] It is worth noting that when the user buckles the cover 12, he or she may not be fully prepared. If the circuit of the drive motor is turned on and the drive motor is started, the torque generated by the drive motor may easily cause the food processing device to vibrate, and there is a risk of the cover 12 slipping out of the hand and reopening.

[0048] like Figure 1 As shown, to solve the above problem, the drive assembly 3 is provided with a start button 32, which is electrically connected to the drive motor. In other words, a safety switch 33 is provided between the start button 32 and the circuit of the drive motor. The drive motor is started only when the safety switch 33 is triggered and the start button 32 is pressed at the same time.

[0049] When the user snaps the cover 12 onto the base 11 , the cover 12 presses the trigger 21 , causing the actuator 22 to trigger the safety switch 33 to conduct the circuit between the start button 32 and the drive motor. When the user is ready, the user can start the drive motor by pressing the start button 32 . The drive motor can drive the basket 131 and the cutter 132 to move relative to each other through the transmission assembly, thereby cutting the food in the basket 131 .

[0050] By setting the start button 32 on the driving assembly 3, it is also possible to avoid the driving motor from starting to drive at the moment of buckling the cover plate 12, causing the main body 1 to vibrate, avoiding the possibility of the cover plate 12 being dropped by the user without being prepared, and ensuring the safety of the user.

[0051] In this embodiment, the food material processing device can be a cutting and preparation machine or a cooking robot. Both the cutting and preparation machine and the cooking robot can process specific food materials. The cutting and preparation machine can quickly complete slicing, shredding, and dicing operations on food materials with uniform thickness and shape, avoiding manual errors and ensuring the appearance and consistency of dishes. The cooking robot can also be equipped with a cutting and preparation function, which can not only physically process food materials but also accurately control the cooking time, seasoning, and time to ensure the taste and doneness of dishes, and has high efficiency in serving dishes, which can alleviate peak pressure.

[0052] In this embodiment, the cover plate 12 is rotatably connected to the base 11 through the shaft assembly 4, so that the user can press the cover plate 12 on the base 11 with one hand to keep it stable, and then control the start button 32 with the other hand, which is convenient to operate.

[0053] In order to further improve the stability of the cover plate 12 and the base 11 when buckling, the base 11 is rotatably provided with a locking piece 15, and the cover plate 12 is provided with a lock catch. When the cover plate 12 is buckled to the base 11, the locking piece 15 can be arranged in the lock catch to lock the base 11 and the cover plate 12. The lock catch can lock the cover plate 12 and the base 11, so as to ensure that the cover plate 12 will not open and cause harm to the user during the cutting operation of the food material, avoiding the existence of safety hazards.

[0054] In this embodiment, the driving assembly 3 is detachably connected to the base 11, the end of the output shaft 34 is provided with an output slot, the inner wall of the output slot is provided with an output tooth, the outer periphery of the input shaft 14 is provided with an input tooth, and the input shaft 14 is inserted and matched with the output slot, and the output tooth abuts against the side wall of the input tooth. When the driving motor drives the output shaft 34 to rotate, the output tooth can drive the input shaft 14 to rotate through the input tooth, thereby providing power for the crank slider mechanism.

[0055] The driving assembly 3 is designed to be detachable from the base 11. On the one hand, it can reduce the occupied space of the food material processing device when not in use, and facilitate storage. On the other hand, it can share the driving assembly 3 with other kitchen appliances, such as blenders, etc., thereby reducing costs.

[0056] As Figure 4As shown, the safety linkage assembly 2 also includes a fixed seat 23 and a connecting rod 24. The fixed seat 23 is fixedly set in the base 11. The connecting rod 24 is rotatably set on the fixed seat 23 through the rotating shaft 25. The actuator 22 is protruded from the base 11. One end of the connecting rod 24 is movably connected to the trigger member 21, and the other end of the connecting rod 24 is movably connected to the actuator 22, so that the trigger member 21 and the actuator 22 move synchronously in opposite directions.

[0057] The rotation of the connecting rod 24 converts the downward pressure of the cover 12 on the trigger 21 into the upward pressure of the actuator 22 on the safety switch 33. In other words, the safety switch 33 is located on the side of the drive assembly 3 facing the base 11. The actuator 22 presses the safety switch 33 to complete the circuit between the start button 32 and the drive motor. This safety linkage assembly 2 is a mechanical structure, which offers advantages over the electronic structure of a microswitch, such as simplicity, high reliability, and low cost.

[0058] like Figure 5 As shown, to automatically reset the safety linkage assembly 2 after the cover 12 is opened, thereby preventing the actuator 22 from triggering the safety switch 33, the safety linkage assembly 2 further includes an elastic member 26. The elastic member 26 is configured to drive the trigger member 21 to move in a direction extending out of the base 11. After the cover 12 is opened, the elastic member 26 can drive the trigger member 21 to move upward. At this time, driven by the connecting rod 24, the actuator 22 descends, thereby disconnecting from the safety switch 33 and preventing the drive motor from being activated.

[0059] It's understandable that when the cover 12 is open, it's still possible for the trigger 21 to be depressed by accidental contact, either by the user or someone else. To further ensure user safety, a protective groove is provided on the side of the cover 12 facing the base 11. When the cover 12 is at its maximum opening angle, the top of the trigger 21 rests within the protective groove. This structure ensures that when the cover 12 is opened, the trigger 21 resets and disconnects the actuator 22 from the safety switch 33, while also preventing the trigger 21 from leaking and creating a safety hazard.

[0060] like Figure 6 As shown, the trigger member 21 is axially spaced apart with a first stopper 212 and a second stopper 213. One end of the connecting rod 24 is positioned between the first stopper 212 and the second stopper 213 and can abut against either the first stopper 212 or the second stopper 213. The trigger member 21 can press one end of the connecting rod 24 downward via the first stopper 212, thereby rotating the connecting rod 24 and driving the actuator 22 upward. Alternatively, the trigger member 21 can lift one end of the connecting rod 24 upward via the second stopper 213, thereby rotating the connecting rod 24 and driving the actuator 22 downward. It is worth noting that the connecting rod 24 and the trigger member 21 are horizontally displaced relative to each other to prevent them from becoming stuck.

[0061] Similarly, as shown in Figure 7 The execution member 22 is axially spaced apart with a third limiting portion 222 and a fourth limiting portion 223, and the other end of the connecting rod 24 is located between the third limiting portion 222 and the fourth limiting portion 223 and can abut against the third limiting portion 222 or the fourth limiting portion 223. When the connecting rod 24 rotates, the execution member 22 can be driven to move upward by the third limiting portion 222 or downward by the fourth limiting portion 223, so that the execution member 22 can trigger or disengage the safety switch 33. It is worth noting that the connecting rod 24 and the execution member 22 also have relative displacement in the horizontal direction, thereby avoiding being stuck.

[0062] The above structure makes the trigger member 21 and the connecting rod 24 without locking structure, and the connecting rod 24 and the execution member 22 also without locking structure, which is convenient for disassembly and improves the efficiency.

[0063] As shown in Figure 6 In order to simplify the structure, the side wall of the trigger member 21 is provided with a first driving groove 211, the upper inner wall of the first driving groove 211 forms a first limiting portion 212, and the lower inner wall of the first driving groove 211 forms a second limiting portion 213. This structure greatly reduces the process flow and cost of producing the trigger member 21, and only needs to process the first driving groove 211 on the outer wall of the pin body.

[0064] Similarly, as shown in Figure 7 The side wall of the execution member 22 is provided with a second driving groove 221, the upper inner wall of the second driving groove 221 forms a third limiting portion 222, and the lower inner wall of the second driving groove 221 forms a fourth limiting portion 223.

[0065] It is worth noting that the first driving groove 211 and the second driving groove 221 are substantially horizontal.

[0066] As shown in Figure 4 and Figure 5 One end of the connecting rod 24 is provided with a first connecting arm 241, and the other end of the connecting rod 24 is provided with a second connecting arm 242, the first connecting arm 241 is arranged between the first limiting portion 212 and the second limiting portion 213, and the second connecting arm 242 is arranged between the third limiting portion 222 and the fourth limiting portion 223.

[0067] Since the force between the first connecting arm 241 and the trigger member 21 is only parallel to the axis of the trigger member 21, but not coincident, the force between the first connecting arm 241 and the trigger member 21 will have a tendency to deflect the trigger member 21.

[0068] As shown in Figure 4 and Figure 5As shown, to address the above problem, two first connecting arms 241 are spaced apart at one end of the connecting rod 24. The trigger member 21 is located between the two first connecting arms 241, and both first connecting arms 241 are movably connected to the trigger member 21. By movably connecting the two first connecting arms to the trigger member 21, the resultant force between the two first connecting arms and the trigger member 21 coincides with the axis of the trigger member 21, ensuring the stability of the trigger member 21 during movement.

[0069] Similarly, the force between the second connecting arm 242 and the actuator 22 is only parallel to the axis of the actuator 22 but does not coincide with it. Therefore, the force between the second connecting arm 242 and the actuator 22 will cause the actuator 22 to have a tendency to deflect.

[0070] like Figure 4 and Figure 5 As shown, to address the above problem, two second connecting arms 242 are spaced apart at the other end of the connecting rod 24. The actuator 22 is located between the two second connecting arms 242, and both second connecting arms 242 are movably connected to the actuator 22. The two second connecting arms are movably connected to the actuator 22, so that the resultant force between the two second connecting arms and the actuator 22 coincides with the axis of the actuator 22, ensuring the stability of the actuator 22 during movement.

[0071] like Figure 4 、 Figure 5 and Figure 8 As shown, the rotating shaft 25 is provided with buckles 251 and limiting protrusions 252 spaced apart along the axial direction. The rotating shaft 25 passes through the fixed seat 23 and the connecting rod 24, with the limiting protrusion 252 abutting one side of the fixed seat 23, and the buckle 251 engaging the other side of the fixed seat 23. After the ends of the connecting rod 24 are respectively connected to the trigger 21 and the actuator 22, the rotating shaft 25 is passed through the fixed seat 23 and the connecting rod 24, and the buckle 251 is engaged with the fixed seat 23, thus completing the installation of the safety linkage assembly 2. The buckle 251 is pressed to disengage it from the fixed seat 23, and the rotating shaft 25 can be removed, thereby disassembling the safety linkage assembly 2.

[0072] like Figure 2 and Figure 3 As shown, the base 11 is provided with at least two positioning pins 16, and the drive assembly 3 is provided with at least two positioning slots 311 corresponding to the at least two positioning pins 16. The positioning pins 16 are plugged into and fit into the corresponding positioning slots 311. When both positioning pins 16 are inserted into the corresponding positioning slots 311, the drive assembly 3 and the base 11 can be locked at a relative angle, ensuring the stability of the food processing device when cutting food.

[0073] It is worth mentioning that when the driving assembly 3 is mounted on the base 11, the safety switch 33 needs to be aligned with the actuator 22. In order to achieve the above purpose, the at least two positioning pins 16 are non-centrally symmetric relative to the axis of the output shaft 34. That is, when the at least two positioning pins 16 of the base 11 are inserted into the corresponding at least two positioning grooves 311 of the driving assembly 3, there is only a specific relative angle between the driving assembly 3 and the base 11, so as to ensure that the safety switch 33 is aligned with the actuator 22, and when the cover plate 12 is buckled, the actuator 22 can trigger the safety switch 33.

[0074] Specifically, the shell 31 of the driving assembly 3 is provided with three positioning grooves 311, and the base 11 is provided with three positioning pins 16. Among them, the three positioning pins 16 are non-centrally symmetric relative to the axis of the output shaft 34, that is, the diameters of the three positioning pins 16 can be different, or the center lines of the three positioning pins 16 are not equidistant on the same circumference.

[0075] In the embodiment, the side of the shell 31 facing the base 11 is provided with a plurality of buffer members 35. The buffer members 35 are pressed by the shell 31 and the base 11, which can not only realize flexible abutment, but also can absorb vibration, reduce the collision between the shell 31 and the base 11, and reduce noise.

[0076] The above is only the preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation manner and application range can be changed, and the content of the description should not be understood as the limitation of the present application.
