[0023] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0024] Example 1 Please see Figures 1 to 6 This application provides a shredding mechanism 100, including a heating plate 10, a blade assembly 20, and a cleaning assembly 30.

[0025] The heating plate 10 is installed on the main unit 50 of the food processor 200; the blade assembly 20 includes a blade shaft 21 and a chopping blade 22 disposed on the blade shaft 21, the blade shaft 21 passing through the heating plate 10; the cleaning assembly 30 includes a mounting bracket 31 and a cleaning brush 32 disposed on the mounting bracket 31, the mounting bracket 31 is connected to the blade shaft 21, the cleaning brush 32 abuts against the surface of the heating plate 10, and is used to rotate around the central axis of the heating plate 10 under the drive of the blade shaft 21 to clean the surface of the heating plate 10.

[0026] The aforementioned shredder mechanism 100 includes a cleaning component 30 mounted on the blade shaft 21. The cleaning brush 32 in the cleaning component 30 abuts against the surface of the heating plate 10. When the blade shaft 21 rotates, it can drive the cleaning brush 32 to rotate on the surface of the heating plate 10, stirring the food adhering to the surface of the heating plate 10 and preventing the heated food from sticking to the surface of the heating plate 10 and affecting the user's health during subsequent use.

[0027] It should be noted that the chopping mechanism 100 is used in the food processor 200, which includes a main unit 50 and a chopping cup 60 mounted on the main unit 50. The main unit 50 is equipped with a drive motor, which is connected to the output shaft and the blade shaft 21, thereby applying a driving force to the blade shaft 21. The heating plate 10 is located at the bottom of the chopping cup 60 and may include a plate body and a heating coil located at the bottom of the plate body. The heating coil can be installed at the bottom of the plate body by welding, so that it can heat the food in the chopping cup 60 after being powered on.

[0028] The blade assembly 20 includes a blade shaft 21 and a chopping blade 22 mounted on the blade shaft 21. To ensure cleanliness, the chopping blade 22 can be detachably connected to the blade shaft 21. This allows the chopping blade 22 to be removed and cleaned with water after food is chopped, preventing food residue from remaining on the blade and causing bacterial growth. Additionally, after food preparation, water can be added to the blending cup 60 to clean the inner surface of the blending cup 60 and the upper surface of the heating plate 10.

[0029] Understandably, in this embodiment, the cutter shaft 21 needs to be electrically connected to the drive motor, so the cutter shaft 21 is made of metal to ensure a certain structural strength. In order to reduce production costs, the cleaning component 30 can be made of non-metallic parts. For example, the mounting bracket 31 can be made of plastic with a certain hardness, and the cleaning brush 32 can be made of plastic with a certain elasticity, such as silicone or rubber, so that when it comes into contact with the surface of the heating plate 10, it is interference-fitted with the heating plate 10, abuts against the surface of the heating plate 10 and deforms, and cleans the surface of the heating plate 10 under the drive of the cutter shaft 21.

[0030] Specifically, the cleaning brush 32 in this embodiment is made of silicone. Since silicone has certain elastic properties, it can always be in contact with the upper surface of the heating plate 10. In addition, silicone is safe and non-toxic, which can improve the safety when cleaning the food processing machine 200.

[0031] Understandably, since the food needs to come into full contact with the chopping blade 22 during the food preparation process, in order to avoid the cleaning brush 32 affecting the flow of the food, the mounting bracket 31 and the blade shaft 21 in this embodiment are detachably connected so that the cleaning component 30 can be disassembled during the food chopping process to avoid affecting the food chopping; at the same time, since the food may need to be heated at high temperatures, this is to prevent the cleaning component 30 from releasing toxic substances after being heated at high temperatures for a long time, which would affect food safety.

[0032] When the mounting bracket 31 is detachably connected to the cutter shaft 21, the mounting bracket 31 can be sleeved on the cutter shaft 21, or clipped onto the cutter shaft 21, or connected by threads, etc.

[0033] Specifically, please refer to Figures 1 to 5 When the mounting bracket 31 is fixed on the cutter shaft 21, the shredder mechanism 100 also includes a fastener 40. The fastener 40 is connected to the end of the cutter shaft 21 away from the heating plate 10 and is used to lock the mounting position of the mounting bracket 31 relative to the cutter shaft 21. Thus, by setting the fastener 40, the material of the fastener 40 can be set as needed, for example, it can be set to a metal material so that it can cooperate with the metal material cutter shaft 21 and realize the installation of the non-metallic mounting bracket 31 on the cutter shaft 21.

[0034] For example, a smooth section and a threaded section can be sequentially arranged on the cutter shaft 21 in the direction away from the heating plate 10. The mounting bracket 31 is sleeved outside the smooth section. The fastener 40 is threadedly connected to the threaded section, and the fastener 40 and the mounting bracket 31 abut against each other. The other end of the mounting bracket 31 abuts against the upper surface of the shredder 22. The mounting bracket 31 is clamped between the shredder 22 and the fastener 40 to fix the mounting bracket 31 on the cutter shaft 21.

[0035] Please see Figures 2 to 5 In one embodiment of this utility model, when fastening the mounting bracket 31, the fastener 40 includes a threaded sleeve 41 and a retaining sleeve 42. The threaded sleeve 41 is threadedly connected to the cutter shaft 21, and the mounting bracket 31 is sleeved outside the threaded sleeve 41. The retaining sleeve 42 is connected to the end of the threaded sleeve 41 away from the heating plate 10 and abuts against the mounting bracket 31. Thus, after the retaining sleeve 42 is disassembled relative to the cutter shaft 21, the mounting bracket 31 can be quickly disassembled relative to the cutter shaft 21.

[0036] To facilitate the disassembly of the mounting bracket 31 relative to the threaded sleeve 41, the outer surface of the threaded sleeve 41 is smooth to reduce friction during fitting and disassembly of the mounting bracket 31. Furthermore, to facilitate the assembly and disassembly of the mounting bracket 31, a section of the threaded sleeve 41 along the length of the cutter shaft 21 is a mating section 411 that mates with the mounting bracket 31. Thus, the outer diameter of the other section of the threaded sleeve 41 (i.e., the clearance section 412, which mates with the retaining sleeve 42) is smaller than the outer diameter of the mating section 411. The mating section 411 is used for fitting the mounting bracket 31. Because of the smaller outer diameter of the clearance section 412, excessive friction between the mounting bracket 31 and the mating section 411 is avoided during assembly and disassembly.

[0037] When the mounting bracket 31 is fitted onto the mating section 411 and rotated by the mating section 411, please refer to [the relevant documentation]. Figure 2 , Figure 3 as well as Figure 5The cross-section of the mating section 411 is set as a polygonal structure, and correspondingly, the cross-section of the mounting hole of the mounting bracket 31 is also set as a polygonal structure, so that when the cutter shaft 21 rotates, the mounting bracket 31 can be rotated by the mating section 411.

[0038] Specifically, the cross-section of the mating section 411 and the cross-section of the mounting hole of the mounting bracket 31 are set as hexagonal structures. In other embodiments, they can also be set as pentagonal, octagonal, or other structures.

[0039] It should be noted that the height of the mounting bracket 31 is greater than the height of the mating section 411, and the mounting bracket 31 is arranged outside the partial clearance section 412 so that it can abut against the lower surface of the abutment sleeve 42 after the abutment sleeve 42 is installed.

[0040] In this embodiment, when the supporting sleeve 42 cooperates with the relief section 412 in the cutter shaft 21, the end of the relief section 412 is provided with a protrusion 413. The protrusion 413 protrudes radially from the relief section 412. The supporting sleeve 42 is sleeved on the protrusion 413 and abuts against the mounting bracket 31 to press the mounting bracket 31 onto the shredder 22. That is, the supporting sleeve 42 is made of a deformable material. When the supporting sleeve 42 is sleeved on the protrusion 413, the protrusion 413 is squeezed and deformed to achieve stable installation on the threaded sleeve 41.

[0041] It should be noted that the threaded sleeve 41 and the cutter shaft 21 are threadedly connected. At the same time, the cutter shaft 21 needs to install the shredder 22. Therefore, the cutter shaft 21 in this embodiment includes at least a first mounting section 211 and a second mounting section 212. The first mounting section 211 is for the shredder 22 to be fitted. The second mounting section 212 is provided with a first external thread 213. The threaded sleeve 41 is provided with a first internal thread 414. The first internal thread 414 and the first external thread 213 are connected.

[0042] Please see Figure 5 and Figure 6 In one embodiment of this utility model, in order to facilitate the cleaning of the mounting bracket 31 and the cleaning brush 32, the cleaning brush 32 and the mounting bracket 31 are detachably connected. Thus, after the grinding cup 60 is cleaned, the entire cleaning assembly 30 can be disassembled, and the mounting bracket 31 and the cleaning brush 32 can be separated to clean the cleaning brush 32 and the mounting bracket 31 separately, so as to avoid hiding dirt and breeding bacteria.

[0043] In achieving the detachable connection between the cleaning brush 32 and the mounting bracket 31, the mounting bracket 31 is provided with a insertion hole 311. The cleaning brush 32 is made of an elastic material, is located in the insertion hole 311, and is interference-fitted with the hole wall of the insertion hole 311. In this way, the cleaning brush 32 can be squeezed and deformed to be locked in the insertion hole 311. When disassembling the cleaning brush 32, external force can be used to disassemble the cleaning brush 32 relative to the mounting bracket 31.

[0044] Furthermore, to ensure the tightness of the cleaning brush 32 on the mounting bracket 31, a locking block 314 is provided on one of the wall of the insertion hole 311 and the side wall of the cleaning brush 32, and a locking groove 321 is provided on the other. The locking block 314 is locked in the locking groove 321. In this way, through the re-cooperation of the locking block 314 and the locking groove 321, more contact area is provided between the mounting bracket 31 and the cleaning brush 32. Along the axial direction of the cutter shaft 21, the side of the locking block 314 contacts the groove wall of the locking groove 321, restricting the separation of the cleaning brush 32 from the mounting bracket 31.

[0045] Specifically, when setting the slot 321 and the block 314, the slot 321 can be set on the cleaning brush 32, and the block 314 can be set on the wall of the insertion hole 311. Since the mounting frame 31 is made of a rigid material, the block 314 is provided on the mounting frame 31, and the slot 321 is provided on the cleaning brush 32 made of elastic material. This makes it easy for the block 314 to be squeezed into the slot 321 when the cleaning brush 32 is squeezed and deformed and installed on the mounting frame 31.

[0046] When setting the locking block 314 and the locking slot 321, only one or multiple locking blocks 314 can be set. Specifically, multiple locking blocks 314 are provided on the wall of the insertion hole 311, and a locking slot 321 is provided on each side of the cleaning brush 32 in the thickness direction. Each locking slot 321 extends radially upward along the cutter shaft 21 and connects to both sides of the cleaning brush 32. Multiple locking blocks 314 located on one side of the cleaning brush 32 are simultaneously locked in one locking slot 321. In this way, by setting only one locking slot 321, it is convenient to open and form the locking slot 321 on the cleaning brush 32.

[0047] In this embodiment, when cleaning the heating plate 10, the cleaning brush 32 is plate-shaped, and the side in contact with the heating plate 10 is a flat plane. When cleaning the heating plate 10 under the drive of the blade shaft 21, the cleaning brush 32 can cover the entire surface of the heating plate 10 and avoid missing any areas.

[0048] Understandably, the shape of the cleaning brush 32 can be adapted to the shape of the inner cavity of the blending cup 60. Furthermore, since the chopping blade 22 includes multiple spaced-apart blades 221, the cleaning brush 32 is positioned between adjacent blades 221 after the cleaning assembly 30 is mounted on the blade shaft 21. The number of cleaning brushes 32 can be set to one or more.

[0049] Please refer to Figure 6 The mounting bracket 31 includes a sleeve portion 312 and a mounting portion 313 provided on the sleeve portion 312. The sleeve portion 312 is sleeved on the mating section 411 of the threaded sleeve 41, and the mounting portion 313 is used to install the cleaning brush 32.

[0050] After the food processor 100 has finished making food, the cleaning component 30 can be installed on the blade shaft 21. The blade shaft 21 is rotated by the drive motor, and the cleaning brush 32 cleans the surface of the heating plate 10 to prevent food residue from causing bacterial growth. When making food, the cleaning component 30 can be disassembled.

[0051] Example 2 Please see Figures 7 to 10 The chopping mechanism 100 provided in the second embodiment of this utility model is largely the same as the chopping mechanism 100 in the first embodiment, except that: In this embodiment, when the abutment sleeve 42 is engaged with the threaded sleeve 41, the abutment sleeve 42 and the threaded sleeve 41 are threadedly connected, so that the abutment sleeve 42 can be engaged with the threaded sleeve 41 by rotation.

[0052] Specifically, the outer wall of the threaded sleeve 41 is provided with a second external thread 415, and the inner wall of the retaining sleeve 42 is provided with a second internal thread 421. The second external thread 415 and the second internal thread 421 are engaged. Furthermore, in order to facilitate the quick disassembly and installation of the retaining sleeve 42 relative to the cutter shaft 21, the pitch of the second external thread 415 is greater than the pitch of the first external thread 213, thereby enabling the quick disassembly and installation of the retaining sleeve 42.

[0053] Example 3 Please see Figure 11 In the third embodiment of this utility model, a food processing machine 200 is also provided, including the above-mentioned chopping mechanism 100. The food processing machine 200 can be a kitchen appliance such as a blender, soy milk maker, or baby food maker.

[0054] The food processing machine 200 includes a main unit 50 and a grinding cup 60 mounted on the main unit 50. The aforementioned shredding mechanism 100 is mounted on the main unit 50 and connected to the drive motor in the main unit 50. The shredding blade 22 is located inside the grinding cup 60, and the blade shaft 21 passes through the heating plate 10 and is partially located inside the grinding cup 21.

[0055] When the food processor 200 needs cleaning, the cleaning component 30 is fitted onto the cutter shaft 21 and secured with fasteners 40. Cleaning liquid is injected into the blending cup 60. After starting the main unit 50, the cleaning brush 32 is driven by the drive motor to rotate. The silicone brush 32 contacts and rubs against the surface of the heating plate 10, ultimately cleaning the surface of the heating plate 10.

[0056] After cleaning the heating plate 10, the food processor 200 can continue to grind the food after removing the retaining sleeve 42 and the cleaning component 30.

[0057] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
