Description

Technical Field

[0001] This utility model belongs to the field of food processor technology, specifically relating to a chopping blade assembly and a food processor. Background Technology

[0002] A food processor is a kitchen appliance, such as a blender, soy milk maker, or juicer. When processing food, it uses a motor to drive blades to rotate and pulverize the food. Specifically, when the driving force is transmitted to the blades, the blades are mounted on a blade shaft to form a single drive unit. The drive shaft, connected to the drive motor, passes through the blade disc and extends into the blade shaft.

[0003] However, in related technologies, in order to facilitate the disassembly and assembly of the cutter shaft, there is a gap between the cutter shaft and the drive shaft. This gap can easily allow slurry to enter during food preparation. If the user forgets to disassemble the cutter shaft for cleaning, it is prone to odor, mold, and bacterial growth after long-term use. Utility Model Content

[0004] The purpose of this invention is to disclose a shredder assembly to solve the problem in the prior art where slurry easily flows into the cutter shaft, leading to mold and odor.

[0005] To achieve the above objectives, one aspect of this utility model discloses a shredder assembly, comprising: The blade module includes a mounting plate and a drive shaft passing through the mounting plate, the mounting plate being mounted on the cup body; A cutting module includes a cutter shaft and a blade disposed on the cutter shaft. The cutter shaft has a mounting hole extending along its own axial direction for the drive shaft to extend into. The sealing structure includes a first sealing ring and a second sealing ring that are axially separated and sleeved on the outside of the drive shaft. The second sealing ring is disposed close to the mounting plate, and the first sealing ring and the second sealing ring are respectively sealed at both ends of the mounting hole in a manner that allows for elastic deformation.

[0006] As an optional implementation, the drive shaft includes a first section, a second section, and a third section with sequentially increasing outer diameters along the axial direction. The third section passes through the mounting plate. The outer wall of the first section is provided with a drive rib for cooperating with the cutter shaft. The outer diameter of the drive rib is smaller than the outer diameter of the second section. The first section and the second section are both located in the mounting hole. The connection between the first section and the second section, and the connection between the second section and the third section, are respectively provided with the first sealing ring and the second sealing ring.

[0007] As an optional implementation, the outer wall of the first segment is provided with a first bayonet, and the end of the second segment facing the third segment is provided with a second bayonet. The first sealing ring and the second sealing ring are respectively engaged in the first bayonet and the second bayonet.

[0008] As an optional implementation, the first sealing ring is disposed at the end of the drive shaft, and the drive rib is located between the first sealing ring and the second sealing ring, and is disposed close to the first sealing ring.

[0009] As an alternative implementation, a protrusion is provided on the outer wall of the end of the cutter shaft away from the blade, and the protrusion extends radially along the cutter shaft.

[0010] As an optional implementation, the cutter shaft is provided with an embedding groove, the embedding groove is disposed facing the mounting plate and is connected to the mounting hole, the diameter of the embedding groove is larger than the diameter of the mounting hole, and the second sealing ring is embedded in the embedding groove.

[0011] As an optional implementation, the cross-sectional height of the embedding groove is greater than the cross-sectional height of the second sealing ring along the axial direction of the drive shaft.

[0012] As an optional implementation, the mounting hole is a blind hole.

[0013] As an optional implementation, the mounting hole is a through hole; The mounting hole includes a constant diameter section and a variable diameter section. The variable diameter section is located away from the mounting plate. The constant diameter section is sealed by the second sealing ring, and the variable diameter section is sealed by the first sealing ring. The inner diameter of the variable diameter section gradually decreases in the direction away from the mounting plate.

[0014] Another aspect of this invention discloses a food processor, including the aforementioned chopping blade assembly.

[0015] Compared with the prior art, the advantages of the chopping blade assembly and food processor of this utility model are as follows: The shredder assembly of this utility model features a sealing structure composed of a first sealing ring and a second sealing ring. The first and second sealing rings are respectively fitted onto the drive shaft along its axial direction. When the drive shaft is installed in the mounting hole, the first and second sealing rings elastically deform and seal both ends of the mounting hole. Thus, the installation of the first and second sealing rings at both ends of the mounting hole effectively blocks the slurry, preventing it from flowing into the mounting hole through the opening and avoiding bacterial growth that could lead to mold and odor, thereby ensuring user safety.

[0024] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0025] Please see Figures 1 to 6 This application provides a shredder assembly 100, including a blade module 10, a shredder module 20, and a sealing structure 30.

[0026] Please refer to Figure 1 and Figure 2The cutter head module 10 includes a mounting plate 11 and a drive shaft 12 passing through the mounting plate 11. The mounting plate 11 is mounted on the cup body. The cutter module 20 includes a cutter shaft 21 and a blade 22 disposed on the cutter shaft 21. The cutter shaft 21 is provided with a mounting hole 211 extending along its own axial direction. The mounting hole 211 is used for the drive shaft 12 to extend into. The sealing structure 30 includes a first sealing ring 31 and a second sealing ring 32 that are separated and sleeved on the drive shaft 12 along the axial direction. The second sealing ring 32 is disposed close to the mounting plate 11, and the first sealing ring 31 and the second sealing ring 32 are respectively sealed at both ends of the mounting hole 211 in a way that causes elastic deformation.

[0027] The aforementioned shredder assembly 100, by setting a sealing structure 30 composed of a first sealing ring 31 and a second sealing ring 32, with the first sealing ring 31 and the second sealing ring 32 respectively sleeved on the drive shaft 12 along the axial direction of the drive shaft 12, when the drive shaft 12 is installed in the mounting hole 211, the first sealing ring 31 and the second sealing ring 32 respectively seal the two ends of the mounting hole 211 in a way that causes elastic deformation. Thus, the two ends of the mounting hole 211 are blocked by the first sealing ring 31 and the second sealing ring 32, preventing the slurry from flowing into the mounting hole 211 from the opening, avoiding the situation of mold and odor caused by bacterial growth, and ensuring the safety of the user.

[0028] It should be noted that, in this embodiment, "sealing both ends of the mounting hole 211 in a way that causes elastic deformation" can mean that the first sealing ring 31 and the second sealing ring 32 are respectively embedded in the mounting hole 211, or one is embedded in the mounting hole 211 and the other abuts against the end face of the mounting hole 211, or both abut against the end faces of both ends of the mounting hole 211, all of which can achieve sealing of both ends of the mounting hole 211.

[0029] Specifically, in this embodiment, the first sealing ring 31 and the second sealing ring 32 are respectively embedded at both ends of the mounting hole 211 to achieve sealing of the mounting hole 211. That is, the first sealing ring 31 and the second sealing ring 32 are respectively squeezed between the cutter shaft 21 and the drive shaft 12 to achieve a better sealing effect.

[0030] Since the drive shaft 12 extends into the mounting hole 211 with the cutter shaft 21 facing the mounting plate 11, when sealing the second sealing ring 32, the cutter shaft 21 has an embedding groove 213. The embedding groove 213 is set facing the mounting plate 11 and is connected to the mounting hole 211. The diameter of the embedding groove 213 is larger than the diameter of the mounting hole 211. The second sealing ring 32 is embedded in the embedding groove 213. In this way, a second sealing ring 32 with a larger outer diameter can be set, thus being embedded in the embedding groove 213 and clamped between the cutter shaft 21 and the drive shaft 12, achieving the effect of sealing the mounting hole 211.

[0031] Specifically, in order to achieve a better sealing effect, the cross-sectional height of the groove 213 along the axial direction of the drive shaft 12 is greater than the cross-sectional height of the second sealing ring 32. This ensures that the second sealing ring 32 is completely installed in the groove 213, so that the flow of slurry into the mounting hole 211 can be blocked by the second sealing ring 32.

[0032] Specifically, please refer to Figures 1 to 6 When the drive shaft 12 and the cutter shaft 21 are fitted together, a fitting rib 24 is provided on the wall of the mounting hole 211. The drive shaft 12 includes a first section 121, a second section 122, and a third section 123 with sequentially increasing outer diameters along the axial direction. The third section 123 passes through the mounting plate 11. A drive rib 124 is provided on the outer wall of the first section 121. A notch 127 is provided on the drive rib 124, and the notch 127 is provided corresponding to the fitting rib 24 so that the fitting rib 24 is inserted into the notch 127. The outer diameter of the drive rib 124 is smaller than the outer diameter of the second section 122. Both the first section 121 and the second section 122 are located in the mounting hole 211. The connection of segment 122 and the connection of the second segment 122 and the third segment 123 are respectively provided with a first sealing ring 31 and a second sealing ring 32. That is, by setting a driving rib 124 in the segment with a smaller outer diameter, when the driving shaft 12 is inserted into the mounting hole 211, since the outer diameter of the driving rib 124 is smaller than the diameter of the mounting hole 211, it is easy to insert the driving shaft 12 into the mounting hole 211. As the driving shaft 12 is gradually inserted, the notch 127 on the driving rib 124 and the mating rib 24 in the mounting hole 211 are inserted and mated, and at the same time, the first sealing ring 31 and the second sealing ring 32 are also installed at both ends of the mounting hole 211.

[0033] Understandably, the drive rib 124 and the wall of the mounting hole 211 are in a clearance fit, as are the second section 122 and the wall of the mounting hole 211. However, the clearance between the second section 122 and the wall of the mounting hole 211 is much smaller than the clearance between the outer wall of the drive rib 124 and the wall of the mounting hole 211. By providing a third section 123 with a larger outer diameter, the entire cutter module 20 can be supported, while allowing for a certain gap between the blade 22 and the mounting plate 11, facilitating the storage of a certain amount of food for the blade 22 to shred.

[0034] Specifically, in this embodiment, the drive rib 124 is integrally formed with the drive shaft 12 and is made of metal, which facilitates the forming of the entire drive shaft 12 while ensuring the structural strength of the drive rib 124.

[0035] The outer wall of the cutter shaft 21 away from the blade 22 has a protrusion 23. The protrusion 23 extends radially along the cutter shaft 21, that is, the protrusion 23 has a larger outer diameter relative to the main body of the cutter shaft 21, so as to facilitate the removal of the entire cutter module 20 relative to the cutter disc module 10 for cleaning.

[0036] Please refer to Figure 5 When installing the first sealing ring 31 and the second sealing ring 32, in order to ensure the accuracy of the installation position of the first sealing ring 31 and the second sealing ring 32, a first latch 125 is provided on the outer wall of the first segment 121, and a second latch 126 is provided at the end of the second segment 122 facing the third segment 123. The first sealing ring 31 and the second sealing ring 32 are respectively latched in the first latch 125 and the second latch 126. In this way, by setting the first latch 125 and the second latch 126, the first sealing ring 31 and the second sealing ring 32 can be latched in respectively, which limits the installation position of the first sealing ring 31 and the second sealing ring 32 and also avoids the first sealing ring 31 and the second sealing ring 32 from shifting when the drive shaft 12 is inserted into the cutter shaft 21.

[0037] Understandably, after the first sealing ring 31 and the second sealing ring 32 are respectively installed on the first bayonet 125 and the second bayonet 126, the first sealing ring 31 and the second sealing ring 32 protrude from the corresponding bayonet so that when they are later installed on the cutter shaft 21, they can undergo elastic deformation under the extrusion of the cutter shaft 21 and be embedded in the wall of the mounting hole 211.

[0038] Understandably, to avoid displacement of the first sealing ring 31 and the second sealing ring 32 when the drive shaft 12 is inserted into the cutter shaft 21, the first sealing ring 31 and the second sealing ring 32 can also be bonded to the drive shaft 12 when they are installed on the first bayonet 125 and the second bayonet 126 respectively, so as to ensure the accuracy of the installation position of the first sealing ring 31 and the second sealing ring 32.

[0039] Furthermore, since the outer diameter of the drive rib 124 is smaller than the diameter of the mounting hole 211, there is a certain gap between them to prevent the slurry from flowing into the mounting hole 211. The first sealing ring 31 is located at the end of the drive shaft 12, and the drive rib 124 is located between the first sealing ring 31 and the second sealing ring 32, and is located close to the first sealing ring 31. In this way, the slurry is prevented from flowing from the opening of the mounting hole 211 to the central area of ​​the mounting hole 211 by the blocking of the first sealing ring 31 and the second sealing ring 32 respectively.

[0040] Specifically, to facilitate subsequent cleaning of the mounting hole 211 of the cutter shaft 21, the mounting hole 211 in this embodiment is a through hole. Water can flow in from one end of the mounting hole 211 and out from the other end, thus achieving the effect of cleaning the cutter shaft 21. Simultaneously, by making the mounting hole 211 a through hole, the forming of the cutter shaft 21 is also facilitated. In other embodiments, to minimize the flow of slurry into the mounting hole 211, the mounting hole 211 can be configured as a blind hole, i.e., the end opposite to the end into which the drive shaft 12 extends is a closed end, thereby directly blocking the flow of slurry into the mounting hole 211.

[0041] Please see Figure 2 and Figure 6 In one embodiment of this utility model, in order to prevent the slurry from flowing into the mounting hole 211 as much as possible, the mounting hole 211 includes a constant diameter section 2111 and a variable diameter section 2112. The variable diameter section 2112 is located away from the mounting plate 11. The constant diameter section 2111 is connected to the embedding groove 213 and is sealed by the second sealing ring 32. The variable diameter section 2112 is sealed by the first sealing ring 31. In the direction away from the mounting plate 11, the inner diameter of the variable diameter section 2112 gradually decreases. Since the drive shaft 12 extends into the mounting hole 211 from the constant diameter section 2111, when the drive shaft 12 extends to the position of the variable diameter section 2112, the inner diameter of the variable diameter section 2112 gradually decreases in the direction away from the mounting plate 11. As a result, the hole wall of the variable diameter section 2112 can press on the first sealing ring 31 to achieve a better sealing effect.

[0042] The aforementioned shredder assembly 100, by embedding a first sealing ring 31 and a second sealing ring 32 at both ends of the mounting hole 211 respectively, can block the flow of slurry from both ends of the mounting hole 211 to the middle region of the mounting hole 211, thereby preventing corrosion and odor; by setting a first latch 125 and a second latch 126 on the drive shaft 12 respectively, the installation positions of the first sealing ring 31 and the second sealing ring 32 can be limited to ensure that they are embedded in the mounting hole 211, thereby ensuring sealing.

[0043] In another embodiment of this utility model, a food processor is also disclosed, including a cup body and the above-mentioned chopping blade assembly 100, wherein the blade module 10 of the chopping blade assembly 100 is installed in the cup body, for example, in a detachable installation manner, so as to facilitate the disassembly and cleaning of the blade module 10 later.

[0044] 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.
