Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment equipment, and particularly relates to a shredding structure for a kitchen waste processor and a kitchen waste processor. Background Art

[0002] As an important link in the management of daily household waste, kitchen waste treatment has attracted more and more attention. Kitchen waste processors have emerged as the times require and are widely used in fields such as families, the catering industry, and food processing. As one of the core components of a kitchen waste processor, the shredding structure plays a key role in the entire treatment process. The design of the shredding structure directly affects the efficiency and effect of waste treatment and the convenience of equipment maintenance.

[0003] However, there are some technical limitations and disadvantages in the shredding structures of many existing kitchen waste processors on the market, which are mainly manifested in the following aspects. The existing shredding structures usually need to be fixedly installed inside the kitchen waste processor. This fixed installation method makes the shredding structure and the processor body an inseparable whole. The shredding structure is closely combined with other components of the kitchen waste processor and cannot be disassembled and replaced separately. This increases the complexity of design and manufacturing, and also brings inconvenience to subsequent maintenance.

[0004] Since the shredding structure is fixedly installed inside the processor or is closely combined with the processor structure, disassembling the shredding structure requires removing other components, which is cumbersome and time-consuming. This design not only increases the workload of maintenance but also may affect the normal operation of other components. Once the shredding structure fails or wears out, maintenance personnel often need to replace the entire processor or its main part, resulting in high maintenance costs. Due to the complex disassembly and maintenance process, professional maintenance personnel are required to operate, and users cannot solve common maintenance problems by themselves.

[0005] Moreover, the fixed shredding structure is difficult to clean comprehensively, and it is easy to accumulate residues and dirt, resulting in a decrease in processing efficiency and a shortening of the service life of the equipment. The long-term accumulated dirt may also cause odors and bacterial growth, affecting the sanitary environment.

[0006] The present utility model is studied and proposed in view of the deficiencies of the prior art. Summary of the Utility Model

[0034] The following will make a detailed description of the embodiments of the present utility model with reference to the accompanying drawings.

[0035] Embodiment 1:

[0036] As Figures 1 to 12 shown, a shredding structure for a kitchen waste processor and a kitchen waste processor in this embodiment include a shredding component 2. The shredding component 2 includes a shredding housing 21, a tool assembly 22, and a first driving component 23. The shredding housing 21 is provided with a shredding cavity 211, an upper opening 222, and a lower opening 223. The tool assembly 22 is rotatably arranged in the shredding cavity 211. The first driving component 23 is in transmission connection with the tool assembly 22. The first driving component 23 can drive the tool assembly 22 to rotate to shred the kitchen waste in the shredding cavity 211. The upper opening 222 and the lower opening 223 are respectively arranged at the upper and lower parts of the shredding housing 21. The upper opening 222 is for the kitchen waste to enter, and the lower opening 223 discharges the shredded small-volume kitchen waste. The shredding housing 21 is provided with a connection component 24 that can be detachably connected to the kitchen waste processor.

[0037] Specifically, by integrating the components of the shredding structure onto the shredding housing 21 and then setting up a connection component 24 on the shredding housing 21 that enables detachable connection with the food waste processor, the detachable connection between the shredding housing 21 and the food waste processor is achieved. This allows the shredding component 2 to be easily detached from the processor for cleaning, maintenance, or replacement. Users can easily disassemble the shredding component 2 without the need for professional tools or skills, simplifying the operation process of equipment maintenance.

[0038] Furthermore, the independent design of the shredding chamber 211 enables the cutter assembly 22 to focus on shredding food waste, improving the shredding efficiency and processing effect. The shredded food waste is quickly discharged through the lower opening 223, avoiding garbage accumulation and enhancing the overall working efficiency of the processor.

[0039] Specifically, the modular design of the shredding component 2 allows each component to be independently replaced and maintained, reducing the replacement cost of the overall processor.

[0040] Furthermore, the independent shredding chamber 211 and the convenient disassembly design contribute to thoroughly cleaning the shredding component 2, maintaining the hygiene and working efficiency of the equipment. The convenient maintenance and cleaning operations help keep the shredding component 2 in good working condition and extend the service life of the equipment.

[0041] Specifically, a shredding chamber 211 is provided inside the shredding housing 21, and the shredding housing 21 allows the entry and exit of food waste through the upper opening 222 and the lower opening 223. Food waste is received through the upper opening 222, and the first drive assembly 23 drives the cutter assembly 22 to perform shredding operations inside the shredding chamber 211. The shredded small-volume food waste is conveyed through the lower opening 223 to the feed port 32, which helps ensure that the food waste is fully shredded before entering the next processing step (such as stirring and drying), improving the efficiency and effect of subsequent processing.

[0042] Furthermore, the shredded garbage has a smaller volume and an increased surface area, which is beneficial for subsequent stirring, drying, and microbial degradation processes, improving the overall processing effect and efficiency. Also, by evenly shredding the garbage, it is possible to avoid blockage problems that may be caused by large pieces of food waste during transportation, making the entire processing flow smoother.

[0043] As Figures 1 to 12 shown, the cutter assembly 22 of this embodiment includes at least two cutter shafts 221. The first drive assembly 23 includes a first drive motor 231 and a connection member 232 located between the cutter shaft 221 and the first drive assembly 23. The first drive motor 231 can drive the cutter shaft 221 to rotate through the connection member 232.

[0044] Preferably, at least two cutter shafts 221 are arranged in parallel or staggered in the shredding chamber 211, and a plurality of blades or cutting teeth are provided on each cutter shaft for shredding kitchen waste. The design of multiple cutter shafts can achieve a more efficient shredding effect, increasing the shredding force and uniformity.

[0045] Through the combination of the first drive motor 231 and the connecting member 232, power can be efficiently transmitted to the cutter shaft 221, achieving stable and strong shredding performance.

[0046] Preferably, the design of at least two cutter shafts 221 increases the cutting surface and cutting angle of shredding, enabling more waste to be processed simultaneously and shredding kitchen waste more evenly, reducing the residue of large pieces of waste. Through efficient shredding, the waste is crushed into smaller and more uniform particles, reducing the risk of blockage during transportation and subsequent processing steps.

[0047] Preferably, the modular design enables the cutter shaft and the connecting member to be easily disassembled and replaced, making maintenance work simpler and reducing the equipment downtime.

[0048] Preferably, in some other embodiments, the user can adjust the spacing between the two cutter shafts 221 in the shredding chamber 211 to adjust the volume of the shredded kitchen waste, and a suitable design can be selected according to actual needs.

[0049] As Figures 1 to 12 shown, the number of cutter shafts 221 in this embodiment is two. Each cutter shaft 221 includes a rotating shaft 2211 and a plurality of blades 2212 provided on the rotating shaft 2211. The plurality of blades 2212 are arranged at intervals along the axial direction of the rotating shaft 2211. Each blade 2212 includes a cutting tool holder 2213 and a blade group 2214 provided on the cutting tool holder 2213. The plurality of blade groups 2214 are spirally distributed on the rotating shaft 2211.

[0050] Specifically, the spirally arranged blade groups can more effectively guide the kitchen waste to the shredding area, improving the shredding efficiency. At the same time, the spiral distribution can continuously cut the kitchen waste, helping to evenly distribute the shredding force, so that the kitchen waste is shredded evenly, reducing the occurrence of large pieces of unshredded kitchen waste.

[0051] Preferably, the spiral blade distribution can help the kitchen waste move forward continuously during the shredding process, thus avoiding the retention of kitchen waste in one position and reducing the risk of blockage.

[0052] Furthermore, the spirally distributed blades can evenly distribute the stress during the shredding process, reducing local excessive wear, thereby prolonging the service life of the blades and the entire equipment.

[0053] As Figures 1 to 12As shown, each of the blade groups 2214 in this embodiment includes at least one cutting blade 2215. Preferably, the number of cutting blades 2215 in this embodiment is multiple, and the multiple cutting blades 2215 are annularly and spacedly distributed on the outer peripheral surface of the cutting tool holder 2213.

[0054] Each blade group 2214 contains multiple cutting blades 2215, which means that the kitchen waste can be cut multiple times within each rotation of the tool shaft 221, thus significantly improving the cutting efficiency.

[0055] Preferably, the design of annular and spaced distribution can evenly distribute the tearing force on the entire outer peripheral surface, avoiding concentration at a certain position. This can not only provide a more uniform tearing effect, but also reduce the large block residues of kitchen waste during the tearing process. The continuous cutting action of multiple cutting blades can better tear and crush the kitchen waste, making the finally produced particles more uniform.

[0056] Preferably, the spacing between the blades can prevent the kitchen waste from accumulating between the blades, reducing the risk of blockage, which is particularly important when dealing with viscous or difficult-to-tear kitchen waste.

[0057] Preferably, the blade groups 2214 on each cutting tool holder 2213 are correspondingly arranged, that is, the cutting blades 2215 on multiple cutting tool holders 2213 correspond one by one, and the corresponding multiple cutting blades 2215 are spirally distributed on the rotating shaft 2211, so that the corresponding multiple cutting blades 2215 are arranged in a staggered manner in multiple directions on the cutting tool holder 2213. By adopting the spiral distribution of multiple corresponding groups of cutting blades on the rotating shaft, a continuous spiral propulsion force can be generated to effectively guide the kitchen waste to the tearing area. This design helps to avoid the kitchen waste getting stuck between the tool shafts 221 and improve the smoothness of feeding.

[0058] Adopting this staggered arrangement design enables multiple cutting blades 2215 to continuously contact the kitchen waste during rotation, realizing continuous cutting, thereby improving the tearing efficiency and ensuring the tearing effect.

[0059] Preferably, in some other embodiments, each blade group 2214 contains only one cutting blade 2215, and a suitable design can be selected according to actual needs.

[0060] Such as Figures 1 to 12As shown, an avoidance gap 2216 is formed between adjacent blades 2212 on each of the rotating shafts 2211 in this embodiment. The avoidance gap 2216 can avoid the blade group 2214. With such a design, the blade groups 2214 on the two rotating shafts 2211 can be staggered, thereby increasing the frequency of the cutting blades contacting the kitchen waste, enabling the kitchen waste to be cut more densely, providing a more delicate and uniform shredding effect, and improving the cutting effect and efficiency.

[0061] Moreover, the distance between the two rotating shafts 2211 is small, making the distance between the blade group 2214 and the rotating shaft 2211 small, ensuring that the kitchen waste can be fully shredded when passing through the blade group. The small distance ensures that there will be no large particle residues during the shredding of the kitchen waste, ensuring that the shredded kitchen waste has a finer particle size.

[0062] Preferably, the angle between each cutting blade 2215 and the cutting tool holder 2213 is an acute angle. The acute angle design makes the blade sharper, enabling it to cut into the kitchen waste more easily, reducing the cutting resistance, and improving the cutting efficiency. The acute angle blade can concentrate the cutting force and apply more force to the kitchen waste during cutting, thereby achieving more efficient cutting.

[0063] As Figures 1 to 12 shown, the connecting member 232 in this embodiment includes a gear set. The gear set includes gears 2321 corresponding to the knife shafts 221 one by one. The gears mesh with each other, and the first drive motor 231 is connected to one of the gears 2321.

[0064] Specifically, each gear corresponds to a knife shaft 221 and is located at the end of the knife shaft. Through the meshing of the gears with each other, a tight transmission system is formed to achieve the synchronous rotation of multiple knife shafts.

[0065] The design of the gear set ensures the efficient transmission of power, reduces energy loss, enables the knife shaft 221 to obtain sufficient and stable power. The meshing design of the gears ensures that all knife shafts can rotate synchronously. The synchronous rotation of multiple knife shafts can perform multi-point and multi-angle shredding simultaneously, effectively improving the shredding ability and uniformity, and enhancing the overall shredding efficiency and effect.

[0066] Preferably, the modular design of the gear set and the knife shaft makes maintenance and replacement more convenient, reduces the equipment downtime, and improves the maintainability of the system.

[0067] Preferably, the shredding component 2 only adopts the design of using one first drive motor 231 to drive the actions of multiple knife shafts 221, reducing the number of motors and the corresponding control and installation costs, and significantly reducing the overall cost of the equipment.

[0068] Preferably, a single motor drives multiple cutter shafts through a gear set to ensure synchronous operation of each cutter shaft, improving shredding efficiency and uniformity.

[0069] Furthermore, the single-motor system has lower energy consumption compared to the multi-motor system, contributing to energy conservation and environmental protection. Also, the noise generated when a single motor operates is usually lower, improving the working environment of the equipment.

[0070] As Figures 1 to 12 shown, the shredding housing 21 of this embodiment includes a main housing 224 and a sub-housing 225 detachably connected to the main housing 224. The main housing 224 is provided with an assembly groove 2251 having an opening. The sub-housing 225 is assembled on the main housing 224 and can block the opening of the assembly groove 2251 to enclose a gear cavity for assembling the gear set. The sub-housing 225 is also provided with an avoidance hole 2252. The first drive motor 231 is assembled on the sub-housing 225, and its output end extends into the gear cavity through the avoidance hole 2252 and is connected to the corresponding gear 2321.

[0071] Specifically, the detachable design of the main housing 224 and the sub-housing 225 forms an enclosed gear cavity, facilitating the installation of the gear set. Moreover, the main housing 224 and the sub-housing 225 can protect the gear set, preventing damage to the gear set due to factors such as collision.

[0072] In addition, the detachable design of the main housing 224 and the sub-housing 225 makes the maintenance and replacement of the gear set more convenient, reducing the equipment downtime and improving the maintainability of the system.

[0073] As Figures 1 to 12 shown, the main housing 224 of this embodiment includes a rear housing 2241 and a front housing 2242. A connecting portion 2243 is provided inside the front housing 2242. The rear housing 2241 is connected to the connecting portion 2243, and the rear housing 2241 can divide the internal space of the front housing 2242 into a shredding cavity 211 and an assembly groove 2251.

[0074] Specifically, the assembly groove 2251 is provided on the main housing 224 and is formed by the cooperation of the front housing 2242 and the rear housing 2241. The sub-housing 225 is detachably connected to the main housing 224 to close the assembly groove 2251 and form a gear cavity for accommodating the gear set.

[0075] The shredding cavity 211 is enclosed by a partial space of the rear housing 2241 and the front housing 2242 for accommodating the cutter assembly 22.

[0076] The cutter assembly 22 and the gear set are respectively arranged in the shredding chamber 211 and the gear chamber. The shredding chamber 211 is used to accommodate and operate the cutter assembly, and the gear chamber is used to accommodate and drive the gear set. Through the partitioning effect of the rear shell 2241, the two chambers are effectively isolated. By arranging the cutter assembly 22 and the gear set in two separate chambers respectively, functional interference is avoided, which facilitates their respective installation and maintenance. The detachable design of the main shell 224 (the rear shell 2241 and the front shell 2242) and the auxiliary shell 225 makes the maintenance and replacement of the gear set and the cutter shaft more convenient, reduces the equipment downtime, and improves the maintainability of the system.

[0077] As Figures 1 to 12 shown, the shredding housing 21 of this embodiment is in the shape of a cuboid. The first drive motor 231 is arranged on one side of the shredding housing 21 and is close to one of the side walls of the shredding housing 21, so that the shredding housing 21 has an avoidance position.

[0078] Preferably, a single motor drive is adopted, which reduces the complexity of the structure of the shredding component 2, reduces the volume of the shredding component 2, enables the shredding component 2 to have a certain avoidance position, enables some structures in the food waste processor to be assembled at the avoidance position, makes the equipment structure more compact, and saves the installation space.

[0079] Preferably, the food waste processor equipped with the shredding structure of this embodiment includes a housing 1 and a stirring barrel 3 arranged in the housing 1. An exhaust passage 16 communicating with the stirring barrel 3 is arranged in the housing 1. The exhaust passage 16 is located at the avoidance position. With such a design, the structure of the food waste processor can be made more compact, which is beneficial to the miniaturization of the volume of the food waste processor.

[0080] As Figures 1 to 12 shown, the connection component 24 of this embodiment includes a plurality of second connection holes arranged on the shredding housing 21.

[0081] Specifically, assembly connection holes corresponding to the second connection holes are arranged in the housing 1. When they are aligned, connection can be achieved through connecting pieces, thereby ensuring the stable connection between the shredding housing 21 and the food waste processor, which has the advantages of simple structure and convenient operation.

[0082] In some other embodiments, the shredding housing 21 and the housing 1 can also adopt connection methods such as clamping and jigging, and appropriate designs can be selected according to actual requirements.

[0083] Preferably, a shredding structure for a food waste processor in this embodiment has multiple gears. Taking the shredding component having five gears as an example, where: For gear 1 of the shredding component, it is used to process very hard food waste, such as extremely hard food waste like large bones (such as beef bones, pork bones), nut shells, etc. The first drive motor 231 drives the cutter shaft 221 to rotate at a relatively low speed, with a large torque, providing the maximum shredding ability, ensuring that hard materials can be processed, effectively shredding very hard waste, and providing the maximum shredding force and shredding efficiency.

[0084] For gear 2 of the shredding component, it is used to process food waste with a relatively hard hardness, such as hard peels (such as coconut shells), hard vegetables (such as carrots), etc. The first drive motor 231 drives the cutter shaft 221 to rotate at a medium - low speed, with a large torque, providing a greater shredding force, increasing the shredding efficiency, ensuring that relatively hard materials can be effectively shredded, and ensuring the shredding effect.

[0085] For gear 3 of the shredding component, it is used to process food waste with a medium hardness, such as fruit pits, small bones, chicken bones, fish bones, etc. The first drive motor 231 drives the cutter shaft 221 to rotate at a medium speed, with a moderate torque, providing sufficient shredding force through the medium speed and torque, ensuring that medium - hardness waste can be efficiently processed. This setting achieves a balance between performance and energy consumption, reduces the risk of blockage, and maintains a stable working noise level.

[0086] For gear 4 of the shredding component, it is used to process food waste between soft and medium hardness, such as ripe fruits, soft meats, soft seafood, etc. The first drive motor 231 drives the cutter shaft 221 to rotate at a relatively high speed, with a small torque, providing a moderate shredding force. Through the relatively high speed and moderate shredding force, the rapid processing of food waste between soft and medium hardness is achieved. This setting can not only ensure efficiency but also achieve the effect of saving energy by shortening the processing time.

[0087] For gear 5 of the shredding component, it is used to process soft food waste, such as fruit peels, vegetable leaves, bread crumbs, etc. The first drive motor 231 drives the cutter shaft 221 to rotate at a high speed, with a relatively small torque, suitable for processing easily shredded soft waste. By quickly and efficiently shredding soft waste, the working time of the shredding component is effectively reduced.

[0088] Preferably, the shredding component further has an automatic reverse mechanism. When excessive resistance is detected, the first drive motor 231 drives the cutter shaft 221 to rotate in reverse, and then drives the cutter shaft 221 to rotate forward, repeatedly cutting the kitchen waste. Through this design of repeatedly switching between forward and reverse rotations, it can ensure that hard kitchen waste can be effectively shredded, and prevent the situation that the cutter shaft 221 is stuck and the shredding component is damaged, ensuring the normal operation of the shredding component.

[0089] Preferably, in some other embodiments, a sensor can also be assembled in the shredding structure to real-time monitor the change of resistance during operation. Based on the sensor data, through the intelligent control system, according to the change of resistance, the first drive motor 231 is controlled to automatically switch to an appropriate gear to adapt to different types of kitchen waste, improving the processing efficiency and equipment protection; or, through the control panel of the kitchen waste processor, an appropriate gear can be manually selected according to the type of kitchen waste, improving the autonomy of operation.

[0090] As Figure 6 shown, the upper solid arrow indicates the feeding direction of the kitchen waste, the middle dotted arrow indicates the rotating and shredding discharging direction of the cutter shaft, and the lower hollow arrow indicates the discharging direction of the kitchen waste, not limited to the feeding, discharging and rotating directions indicated by these arrows.

[0091] As Figure 7 shown, the middle dotted arrow indicates the retracting rotation and discharging direction of the cutter shaft.

[0092] As Figures 1 to 12 shown, the kitchen waste processor of this embodiment includes a housing 1 and the shredding structure for the kitchen waste processor as described in any one of the above. The housing 1 is provided with a first assembly cavity 15 for assembling the shredding component 2. By arranging the shredding component 2 in the housing 1, the defect that the traditional processor has no shredding function is effectively solved, the processing efficiency is improved, and moreover, the shredded small-volume kitchen waste is heated and fully stirred, which can accelerate the degradation and processing process of the kitchen waste, reduce the odor and pest problems, and improve the sanitary level of the kitchen.

[0093] Embodiment 2

[0094] Embodiment 2 further has the following implementation manners on the basis of Embodiment 1.

[0095] The front housing 2242 of this embodiment includes a front side housing 2244, a left side housing 2245, and a right side housing 2246. The connecting portion 2243 includes first connecting holes which are correspondingly arranged on the inner side walls of the left side housing 2245 and the right side housing 2246. On the inner side walls of the left side housing 2245 and the right side housing 2246, there are also correspondingly arranged limiting protrusions 2247. The limiting protrusions 2247 correspond one by one to the cutter shafts 221. On each of the limiting protrusions 2247, there is a blade groove 2248 which corresponds one by one to the blades on the corresponding cutter shaft 221.

[0096] Specifically, the front housing 2242 includes a front side housing 2244, a left side housing 2245, and a right side housing 2246. The three form the main part of the front housing. The connecting portion 2243 includes first connecting holes which are correspondingly arranged on the inner side walls of the left side housing 2245 and the right side housing 2246 for connecting with the rear housing 2241 to ensure the structural stability.

[0097] Preferably, the limiting protrusions 2247 are arranged on the inner side walls of the left side housing 2245 and the right side housing 2246, corresponding one by one to the cutter shafts 221. On each limiting protrusion 2247, there is a blade groove 2248 which corresponds one by one to the blades on the corresponding cutter shaft 221, ensuring that the blades maintain the correct positioning and angle during the working process, improving the shredding efficiency, improving the shredding efficiency and stability, and being able to reduce the space in the shredding chamber 211, making the space in the shredding chamber 211 more compact, avoiding the situation that kitchen waste falls into other spaces in the shredding chamber 211, resulting in the cutter assembly 22 being unable to shred this part of the kitchen waste, ensuring the shredding efficiency of the shredding components, and ensuring that the shredding components can work normally, and minimizing the impact of kitchen waste on the shredding components as much as possible.

[0098] Moreover, the detachable design of the main housing 224 (the rear housing 2241 and the front housing 2242) and the auxiliary housing 225 makes the maintenance and replacement of the gear set and the cutter shafts more convenient. The blade grooves 2248 can also play a role in positioning and assembly, further optimizing the assembly process.

[0099] Preferably, the blade 2212 includes a cutting tool holder 2213 and a cutting edge group 2214 arranged on the cutting tool holder 2213. Each cutting edge group 2214 includes at least one cutting edge 2215. The distance between the cutting edges 221 on one rotation shaft 2211 and another rotation shaft 2211 is α, where α satisfies: 0mm ≤ α ≤ 2mm;

[0100] With such a design, the distance between the cutter shafts 221 is small, enabling the two cutter shafts 211 to cooperate more closely, ensuring that kitchen waste is shredded evenly and effectively, thus achieving a finer shredding effect. Moreover, an appropriate distance α can also prevent the accumulation of kitchen waste in the cutting area. If the distance is too large, the kitchen waste may be discharged from the lower opening 223 without sufficient shredding, affecting the shredding effect.

[0101] Preferably, the blade groove 2248 is concentric with the blade 2212, and the concentric distance between the blade groove 2248 and the blade 2212 is β, where β satisfies: 0.25 mm ≤ β ≤ 2 mm. With such a design, the distance between the cutting edge 221 of the cutter and the inner wall of the blade groove 2248 is closer. When shredding kitchen waste, the cutting edge 221 of the cutter can also cooperate with the inner wall of the blade groove 2248, forcing the kitchen waste between the two to continuously press against the cutting edge 221 under the pressure of the inner wall of the blade groove 2248, enabling the kitchen waste to be shredded sufficiently, thereby controlling the thickness of the kitchen waste material and ensuring that the shredded kitchen waste meets the expected particle size requirements.

[0102] Moreover, an appropriate distance β can also prevent the kitchen waste from escaping from the cutting area during the shredding process. If the distance is too large, the kitchen waste may escape through the gap between the cutting edge 221 of the cutter and the inner wall of the blade groove 2248, affecting the shredding effect; if the distance is too small, it may lead to an increase in the friction between the cutting edge 221 of the cutter and the inner wall of the blade groove 2248, affecting the operating efficiency of the equipment.

[0103] Preferably, the cross-sectional shape of the blade groove 2248 is an inferior arc shape, and the side wall edge of the blade groove 2248 matches the acute angle of the cutting edge of the cutting edge 2215 of the cutter, so that when the cutting edge 2215 of the cutter enters the blade groove 2248, an acute angle cutting is formed between the two. With such a design, the cutting resistance received by the cutting edge 2215 of the cutter can be reduced, making the cutting smoother and improving the cutting efficiency.

[0104] Preferably, each of the limiting protrusions 2247 includes a limiting seat 2249 and a plurality of spaced limiting pieces 22491 provided on the limiting seat 2249. The blade groove 2248 is located between two corresponding limiting pieces 22491. Each of the limiting pieces 22491 extends into the corresponding avoidance gap 2216. The radian of each of the limiting pieces 22491 is similar to or equal to the side wall radian of the rotating shaft 2211. Being similar, with such a design, the limiting piece 22491 extends into the avoidance gap 2216 to form a physical obstacle, and in cooperation with the side wall of the shredding cavity 211, it can limit the free movement of kitchen waste during the cutting process, preventing the kitchen waste from rotating or turning back during the cutting process. This physical limitation ensures that the kitchen waste maintains a stable position within the cutting area, contributing to achieving uniform and effective cutting.

[0105] Embodiment 3

[0106] Embodiment 3 further has the following implementation manners on the basis of Embodiment 2.

[0107] Preferably, the rotating shaft 2211 and the blade 2212 are detachably connected. The cutting tool holder 2213 is provided with polygonal assembly holes. The cutting tool holder 2213 is detachably connected to the rotating shaft 2211 through the polygonal assembly holes. The rotating shaft 2211 is provided with spacers 2217 between adjacent blades 2212 to ensure a uniform spacing between the blades 2212 and prevent collision and interference between the blades 2212. With the detachable connection design of the blade and the rotating shaft, the daily maintenance and blade replacement of the equipment are more convenient, greatly reducing the downtime.

[0108] Furthermore, the design of the polygonal assembly holes provides a more stable connection, ensuring that the tool holder will not slip or loosen under high load conditions.

[0109] Preferably, the spacing α in this embodiment is the spacing between the cutting edge 221 on one rotating shaft 2211 and the spacer 2217 on the other rotating shaft 2211.

[0110] Embodiment 4

[0111] Embodiment 4 further has the following implementation manners on the basis of Embodiment 2.

[0112] In this embodiment, the rear shell 2241 and the front side shell 2244 respectively abut against both sides of each limiting protrusion 2247 to ensure the stable positioning of the knife shaft, further ensuring the stability of the knife shaft and the blade, facilitating their respective installation and maintenance. With such a design, the space within the shredding cavity 211 can be further compressed, making the space within the shredding cavity 211 more compact, and enabling the shredding structure to be more compact, which is beneficial to the miniaturization of the shredding structure.
