Description

Technical Field

[0001] This invention relates to the field of food waste disposers, specifically a food waste disposer. Background Technology

[0002] Existing household food waste disposers allow users to place food waste into the food waste bin. The disposer uses a grinding blade to grind the food waste into smaller fragments. The heating element then heats the food waste in the bin to evaporate moisture, reducing leachate production. The processed food waste is easily absorbed by plants and can be used as organic fertilizer, thus achieving the effect of reusing the processed food waste.

[0003] Existing household food waste disposers are designed with detachable food waste bins for easy disposal and cleaning. However, food waste typically contains fruits, vegetables, or bones. Current disposers need to effectively convert larger or harder food waste into smaller fragments. For example, the disposer disclosed in Chinese Patent Publication No. CN212069887U has a crushing component connected to the output gear via an output shaft. However, this type of disposer has low torque and cannot completely cut the food waste. This results in uncut food waste easily getting stuck on the mixing blades, preventing it from functioning properly. It can only perform simple mixing and cutting of small and soft fruits and vegetables. Due to its low processing efficiency, it does not meet the needs of customers. In addition, it uses an upper six-tooth meshing connector and a lower six-tooth meshing connector to connect the mixing blades and the drive component. When the crushing component is connected to the drive component, the teeth of the upper six-tooth meshing connector need to be aligned and engaged with the grooves of the lower six-tooth meshing connector in sequence to ensure that the output torque can drive the crushing component to cut the kitchen waste into smaller fragments. If the upper six-tooth meshing connector and the lower six-tooth meshing connector are not connected accurately, the six-tooth meshing connector is easily damaged when the drive component starts. Summary of the Invention

[0004] To address the aforementioned technical problems of existing food waste disposers, such as insufficient torque for thoroughly cutting food waste, the need for the upper six-tooth connector to connect and align with the lower six-tooth connector leading to potential misalignment and damage to the six-tooth connector during operation, the present invention provides the following technical solution:

[0005] A food waste disposer includes a food waste bin, a stirring blade, and a drive assembly. The food waste bin has a stirring chamber, the stirring blade is disposed within the stirring chamber, a connecting sleeve is provided between the stirring blade and the drive assembly, the stirring blade has a connecting shaft, the stirring blade has an installation cavity, the connecting shaft is fixedly disposed on the installation cavity, the connecting sleeve includes a first connecting sleeve connected to the connecting shaft and a second connecting sleeve connected to the drive assembly, the first connecting sleeve has a first connecting cavity for accommodating the second connecting sleeve, the first connecting sleeve is sleeved on the outside of the second connecting sleeve, the first connecting sleeve and the second connecting sleeve are connected by a snap-fit ​​structure, and the food waste bin also has an opening for the connecting shaft and the first connecting sleeve to pass through.

[0006] To improve the stability of the connection between the first connecting sleeve and the second connecting sleeve, the engaging structure includes multiple connecting grooves disposed on the first connecting cavity and multiple engaging portions disposed on the outside of the second connecting sleeve and cooperating with the connecting grooves.

[0007] To improve the ease of connection between the first and second connecting bushings, multiple connecting grooves and multiple engaging portions are spaced apart, with the number of connecting grooves being greater than or equal to the number of engaging portions. Both the connecting grooves and the engaging portions are arc-shaped.

[0008] To improve the stability of the connection between the first connecting sleeve and the connecting shaft, the other end of the connecting shaft is provided with a locking part, one end of the first connecting sleeve is provided with a first connecting groove that mates with the locking part, a screw is provided between the connecting shaft and the first connecting sleeve, the connecting shaft is provided with a threaded cavity that mates with the screw, and the first connecting sleeve is provided with a first connecting sleeve opening, the inner diameter of the first connecting sleeve opening being smaller than the outer diameter of the top of the screw.

[0009] To improve the stability of the connection between the second connecting bushing and the drive assembly, the drive assembly is provided with a drive shaft, the drive shaft is connected to the second connecting bushing, the second connecting bushing is provided with a second connecting cavity, and the second connecting cavity is provided with a second connecting groove that matches the shape of the drive shaft and is used to engage the drive shaft.

[0010] To improve the sealing and stability of the mixing blades and drive assembly, the food waste bin is provided with a mounting platform. The opening includes a first opening on the mounting platform and a second opening at the bottom of the food waste bin. A seal and a bearing are connected between the connecting shaft and the mounting platform.

[0011] To improve the sealing performance between the stirring blade and the drive assembly, the mounting platform is provided with a first step and a second step, and the sealing element includes a shaft seal disposed between the first opening and the upper side of the first step.

[0012] To reduce wear between the connecting shaft and the mounting platform, the bearing includes a first bearing disposed between the first step and the connecting shaft, and a second bearing disposed between the second step and the connecting shaft.

[0013] To improve the sealing performance between the stirring blade and the drive assembly, a connecting shaft step is provided on the connecting shaft, and the sealing element includes a first sealing element disposed between the outer side of the first opening and the connecting shaft step.

[0014] To improve the heating effect of the food waste disposer, the bottom of the food waste bin is provided with a non-removable, ring-shaped heating component. The heating component has an arc-shaped heating shell and a straight conductive shell connected to the arc-shaped heating shell. A heating wire is provided inside the arc-shaped heating shell. A conductive end is provided on the straight conductive shell. The conductive end includes a connecting core rod connected to the heating wire and a contact point connected to the connecting core rod. A conductive part is provided on the drive component connected to the contact point. One end of the connecting core rod is fixedly disposed inside the straight conductive shell.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The food waste bin is detachably mounted on the drive assembly. When the food waste bin is detached from the drive assembly for emptying, it drives the agitator blades in the mixing chamber, causing the first connecting sleeve and the second connecting sleeve to separate. When the food waste bin is connected to the drive assembly, the connecting shaft is non-detachably mounted on the agitator blades, ensuring the stability of the connection. Since the other end of the connecting shaft is connected to the first connecting sleeve, which is fitted over the second connecting sleeve, the connection between the first and second connecting sleeves forms a stable locking structure. When the drive assembly operates, the second connecting sleeve drives the first connecting sleeve, causing the first connecting sleeve to rotate and drive the connecting shaft. The connecting shaft then drives the agitator blades to agitate. This connection method reduces energy consumption during transmission. The reduced wear and tear, in turn, increases the torque of the stirring blades. These blades can thoroughly cut food waste, effectively converting larger or harder pieces into smaller fragments. This prevents uncut food waste from getting stuck on the blades and hindering normal operation. The connecting shaft design effectively improves the processing efficiency of the food waste disposer, further meeting customer needs. The connecting bushing design ensures the transmission efficiency and stability of the disposer. Compared to traditional technologies, it eliminates the need to align the teeth and grooves sequentially, greatly improving connection convenience and preventing misalignment during connection between the first and second connecting bushings, which could damage the connecting bushings during operation.

[0017] 2. By setting a seal between the connecting shaft and the mounting platform, this invention can prevent uncut materials from getting stuck on the mixing blades and preventing them from operating normally. The bearing configuration reduces wear between the connecting shaft and the mounting platform, effectively improving the processing efficiency of grinding and mixing, and further meeting the needs of customers.

[0018] 3. The present invention, through the heating component connected to the food waste bin, can directly heat the bottom of the food waste bin, reducing heat transfer loss, ensuring the food waste bin is continuously and evenly heated, improving heating efficiency. The connecting core rod can enhance the structural stability of the heating component under long-term insertion and removal, improve the lifespan of the heating component, and enhance the user experience.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A food waste disposer is shown, comprising a food waste bin 2, a stirring blade 3, and a drive assembly 4. The food waste bin 2 has a stirring chamber 21, and the stirring blade 3 is disposed within the stirring chamber 21. A connecting bushing 5 is provided between the stirring blade 3 and the drive assembly 4. The stirring blade 3 has a connecting shaft 32, and the stirring blade 3 has an installation cavity 31. The connecting shaft 32 is fixedly disposed on the installation cavity 31. The connecting bushing 5 includes a first connecting bushing 51 connected to the connecting shaft 32 and a second connecting bushing 52 connected to the drive assembly 4. The first connecting bushing 51 has a first connecting cavity 511 for accommodating the second connecting bushing 52. The first connecting bushing 51 is sleeved on the outside of the second connecting bushing 52. The first connecting bushing 51 and the second connecting bushing 52 are connected by a snap-fit ​​structure 53. The food waste bin 2 also has an opening for the connecting shaft 32 and the first connecting bushing 51 to pass through. The food waste bin is detachably mounted on the drive assembly. When the food waste bin is detached from the drive assembly for emptying, it drives the agitator blades in the mixing chamber, causing the first connecting sleeve and the second connecting sleeve to separate. When the food waste bin is connected to the drive assembly, the connecting shaft is non-detachably mounted on the agitator blades, ensuring the stability of the connection. Since the other end of the connecting shaft is connected to the first connecting sleeve, which is fitted over the second connecting sleeve, the connection between the first and second connecting sleeves forms a stable locking structure. When the drive assembly operates, the second connecting sleeve drives the first connecting sleeve, causing the first connecting sleeve to rotate and drive the connecting shaft. The connecting shaft then drives the agitator blades to agitate. This connection method reduces energy loss during transmission. This design reduces wear and tear, thereby increasing the torque of the stirring blades. The stirring blades can thoroughly cut food waste and effectively convert large or hard food waste into smaller fragments, preventing uncut food waste from getting stuck on the stirring blades and preventing them from operating properly. The connecting shaft design effectively improves the processing efficiency of the food waste processor, further meeting customer needs. The connecting bushing design ensures the transmission efficiency and stability of the food waste processor. Compared with traditional technology, it is not necessary to align the teeth and grooves sequentially. This invention greatly improves the convenience of connection and avoids the situation where the first and second connecting bushings are easily misaligned during connection, causing damage to the connecting bushings during operation.

[0032] Preferably, the connecting shaft is installed on the mounting cavity using non-removable methods such as die casting or riveting, which allows the connecting shaft to be more tightly and stably connected within the mounting cavity, ensuring the structural stability and transmission efficiency of the connecting shaft. Furthermore, the connecting shaft can be installed on the mounting cavity using methods such as cold pressing or hot melting.

[0033] like Figure 2The illustrated food waste disposer includes a locking structure 53 comprising multiple connecting grooves 512 disposed on the first connecting cavity 511 and multiple locking portions 521 disposed on the outside of the second connecting sleeve 52 and engaging with the connecting grooves 512. The engagement of the multiple connecting grooves and multiple locking portions improves the stability of the connection between the first and second connecting sleeves and increases transmission efficiency. When the drive assembly is running, the locking portions of the second connecting sleeve can drive the connecting grooves on the first connecting sleeve, thereby driving the stirring blades to stir and cut the food waste within the stirring chamber.

[0034] Furthermore, the engaging structure 53 includes multiple engaging portions 521 disposed on the first connecting cavity 511 and multiple connecting grooves 512 disposed on the outside of the second connecting sleeve 52 and cooperating with the engaging portions 521. This design, with multiple connecting grooves cooperating with multiple engaging portions, improves the stability of the connection between the first and second connecting sleeves and increases transmission efficiency. When the drive assembly is running, the engaging portions on the first connecting sleeve can be driven by the connecting grooves of the second connecting sleeve, thereby driving the stirring blades to stir and cut the kitchen waste within the stirring chamber.

[0035] Furthermore, the present invention adopts a design in which the first connecting sleeve is sleeved on the outside of the second connecting sleeve. When the second connecting sleeve 52 is provided with a second connecting cavity 522 that can accommodate the first connecting sleeve 51, and the second connecting sleeve 52 is sleeved on the outside of the first connecting sleeve 51, and the inner diameter of the second connecting cavity 522 is larger than the outer diameter of the first connecting sleeve 51, its engagement structure is the same as that in the above embodiments.

[0036] like Figure 2 The illustrated food waste disposer includes multiple spaced connecting grooves 512 and multiple spaced engaging portions 521, with the number of connecting grooves 512 being greater than or equal to the number of engaging portions 521. Both the connecting grooves 512 and the engaging portions 521 are arc-shaped. When the engaging portion of the second connecting sleeve drives the connecting grooves on the first connecting sleeve, thereby driving the stirring blades to stir and cut food waste within the stirring chamber, the number of connecting grooves being greater than or equal to the number of engaging portions reduces the possibility of incompatibility between the connecting grooves and engaging portions when the first connecting sleeve is fitted over the second connecting sleeve, enabling quick alignment and minimizing connection deviations.

[0037] When the connecting groove of the second connecting sleeve drives the engaging part on the first connecting sleeve, thereby driving the stirring blade to stir and cut the kitchen waste in the stirring chamber, the number of connecting grooves is greater than or equal to the number of engaging parts. When the first connecting sleeve is fitted on the outside of the second connecting sleeve, the incompatibility between the connecting grooves and engaging parts is reduced, and the alignment can be quickly achieved and the connection deviation can be reduced.

[0038] Furthermore, the curved surface of the connecting groove and the curved surface of the engaging part allow for more precise and faster connection, enabling automatic alignment. Additionally, the surface of the connecting groove can be non-curved, and the engaging part can be configured as a non-curved surface that matches its shape, allowing the connecting groove and engaging part to mesh at different angles.

[0039] like Figure 2 and Figure 4 The illustrated food waste disposer includes a connecting shaft 32 with a locking end 322 at one end, and a first connecting sleeve 51 with a first connecting groove 54 that engages with the locking end 322 at one end. A screw 6 is positioned between the connecting shaft 32 and the first connecting sleeve 51. The connecting shaft 32 has a threaded cavity that engages with the screw 6. The first connecting sleeve 51 has a first connecting sleeve opening 513, the inner diameter of which is smaller than the outer diameter of the screw 6's tip. This design allows the screw to connect tightly to the connecting shaft by engaging with the threaded cavity. The screw's placement between the connecting shaft and the first connecting sleeve improves transmission efficiency. Furthermore, the first connecting sleeve opening, with its inner diameter smaller than the outer diameter of the screw's tip, allows the screw to pass through one side of the opening and connect to the threaded cavity on the connecting shaft. This screw placement prevents the connecting shaft from wobbling and disengaging when the first connecting sleeve drives the connecting shaft to rotate. When the first connecting sleeve rotates, the first connecting groove drives the engaging end to rotate simultaneously. Through the engagement of the engaging end and the first connecting groove, the stability and transmission efficiency of the connection between the connecting shaft and the first connecting sleeve can be further improved.

[0040] like Figure 2 and Figure 4The illustrated food waste disposer includes a drive assembly 4 with a drive shaft 41 connected to a second connecting sleeve 52. The second connecting sleeve 52 has a second connecting cavity 522 and a second connecting groove 523 that matches the shape of the drive shaft 41 and engages with it. When the drive assembly operates, it drives the drive shaft to rotate, which in turn drives the second connecting sleeve to rotate the first connecting sleeve. This design ensures efficient transmission. Because the drive shaft is connected within the second connecting cavity, the second connecting groove engages with the drive shaft when it rotates, preventing it from loosening and further improving the stability and transmission efficiency of the connection between the drive shaft and the second connecting sleeve. Furthermore, the second connecting sleeve has a second connecting sleeve connecting groove that accommodates the tip of a screw. The second connecting sleeve connecting groove abuts against or approaches the tip of the screw, preventing the second connecting sleeve from moving further upward or loosening.

[0041] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The illustrated food waste disposer includes a food waste bin 2 with a mounting platform 22. The openings include a first opening 23 on the mounting platform 22 and a second opening 24 at the bottom of the food waste bin 2. A sealing element 7 and a bearing 8 are connected between a connecting shaft 32 and the mounting platform 22. The mounting platform is installed inside the mixing chamber and protrudes upwards. Its upward-protruding shape, which mates with the mixing blades, further elevates the mixing blades, creating a gap between them and the food waste bin. The first opening is located on the mounting platform, and the second opening is located at the bottom of the food waste bin. The connecting shaft extends through the first opening towards the second opening, and a first connecting shaft sleeve extends through the second opening towards the first opening. When the connecting shaft is connected to the first connecting shaft sleeve, the mixing blades are connected to the drive assembly via the connecting shaft sleeve.

[0042] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The illustrated food waste disposer has a mounting platform 22 with a first step 221 and a second step 222. The sealing element 7 includes a shaft seal 71 disposed between the first opening 23 and the upper side of the first step 221. This design, with the shaft seal positioned below the opening and between the lower side of the opening and the upper side of the first step, prevents vertical movement of the shaft seal. The shaft seal further prevents steam and liquid from entering the mounting platform from the mounting cavity, ensuring the stability of the connection between the mixing blades and the drive assembly.

[0043] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The illustrated food waste disposer includes a bearing 8 comprising a first bearing 81 disposed between the first step 221 and the connecting shaft 32, and a second bearing 82 disposed between the second step 222 and the connecting shaft 32. One end of the first bearing is engaged with the first step and the other end extends toward the second step, and one end of the second bearing is engaged with the second step and the other end extends toward the first step. The bearings further secure the connecting shaft, improving its stability during movement and preventing displacement due to vibration during rotation. Furthermore, the bearings are made of composite materials, with graphene lubrication layers on both the inner and outer sides to reduce wear between the bearing and the connecting shaft, and between the bearing and the mounting platform.

[0044] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The illustrated food waste disposer has a connecting shaft 32 with a connecting shaft step 321. The sealing element 7 includes a first sealing element 72 disposed between the outer side of the first opening 23 and the connecting shaft step 321. By providing a first sealing element between the outer side of the first opening and the connecting shaft step, solids, gases, or liquids can be prevented from entering the inner side of the mounting platform from the mounting cavity, ensuring the connection stability between the stirring blades and the drive assembly. The sealing effect can be further improved by providing multiple first sealing elements. The diameter of the first sealing element should be larger than the outer diameter of the first opening. When multiple first sealing elements are provided, one of the first sealing elements can completely cover the upper side of the first opening.

[0045] Furthermore, a shim 323 is also provided on the connecting shaft 32, and the shim 323 is disposed between the connecting shaft 32 and the first connecting bushing 51. Furthermore, the shim can further reduce wear caused by collision between the connecting shaft and the connecting bushing, and at the same time reduce energy loss during transmission, thereby improving transmission efficiency.

[0046] Furthermore, the connecting bushing 5 is made of metal or resin. When the connecting bushing is made of metal, its durability, temperature resistance, and service life can be improved. When the connecting bushing is made of resin, its cost can be reduced, and it is also easier to replace.

[0047] like Figure 8 , Figure 9 , Figure 10 and Figure 11The illustrated food waste disposer includes a non-removable, ring-shaped heating assembly 9 at the bottom of the food waste bin 2. The heating assembly 9 has an arc-shaped heating shell 91 and a straight conductive shell 92 connected to the arc-shaped heating shell 91. A heating wire 911 is provided inside the arc-shaped heating shell 91. A conductive end 921 is provided on the straight conductive shell 92. The conductive end includes a connecting core rod 9211 connected to the heating wire 911 and a contact point 9212 connected to the connecting core rod 9211. A driving assembly 4 has a conductive part 42 connected to the contact point 9212. One end of the connecting core rod 9211 is fixedly disposed inside the straight conductive shell 92. Furthermore, the annular heating element is positioned near the outer periphery of the bottom of the food waste bin. This heating element transfers heat to the bottom of the bin during heating, while remaining away from the connecting sleeve located at the opening, preventing high heat radiation to the connecting sleeve surface and extending its lifespan. The heating wire within the arc-shaped heating housing is annularly connected to the periphery of the bottom of the food waste bin. In this invention, there are two contacts connecting to the connecting core rod. One end of the connecting core rod is located within the straight conductive housing, and the other end extends outward. A threaded cap 93 is fitted between the straight conductive housing and the other end of the connecting core rod. The straight conductive housing allows the connecting core rod to have a straight structure, with the two contacts on the same straight line. This makes it easier for the contacts to connect or disconnect from the conductive part when the food waste bin is connected to or disconnected from the drive assembly. Since the food waste bin is detachably connected to the drive assembly, when the contacts are connected to the conductive part, the heating assembly is energized and heats the bottom of the food waste bin. Frequent plugging and unplugging affects the connection stability of the heating assembly. By setting a connecting core rod with one end fixed inside the straight conductive housing, the structural rigidity of the heating assembly is enhanced. Furthermore, one end of the connecting core rod is fixed to the straight conductive housing by die casting. The connecting core rod is made of iron or stainless steel, the contacts are made of nickel-plated copper alloy, and the heating wire is made of iron.

[0048] like Figure 8 , Figure 9 , Figure 10 and Figure 11The illustrated food waste disposer includes a drive assembly 4 equipped with a temperature sensor 10 for measuring the temperature of the bottom of the food waste bin 2. The bottom of the food waste bin 2 has a downwardly protruding food waste bin connecting part 25, which is connected to the temperature sensor 10. With this design, the temperature of the food waste bin is transferred from the bottom to the food waste bin connecting part. The temperature sensor, connected to the food waste bin connecting part, controls the start and stop of the heating assembly, precisely controlling the temperature of the food waste bin. To improve the lifespan of the temperature sensor, it is fixed to the drive assembly to prevent damage from impacts. When the food waste bin is lifted, the food waste bin connecting part detaches from the temperature sensor; when the food waste bin is connected to the drive assembly, the food waste bin connecting part on the food waste bin connects to the temperature sensor on the drive assembly.

[0049] This invention utilizes a heating component connected to the bottom of the food waste bin to directly heat the bottom, reducing heat transfer loss and ensuring even and continuous heating, thus improving heating efficiency. The temperature sensor, directly connected to the bottom of the bin, allows for more precise temperature control, preventing localized heating of the bottom and the resulting burnt and sticky food waste that is difficult to clean, thereby enhancing the user experience. The heating component can be connected to the bottom of the food waste bin via methods such as welding or die-casting; preferably, it is die-cast.

[0050] Furthermore, the outer edge of the food waste bin 2 extends downward and forms a food waste bin mounting cavity 26 with the bottom of the food waste bin 2. The food waste bin mounting cavity 26 is provided with a fixing groove 261 for fixing the heating component 9. The fixing groove 261 has a ring structure. By fixing the heating component with the fixing groove, the heat of the heating component is better transferred upward, improving the heat transfer efficiency. The design of the ring structure fixing groove has the advantages of simple structure, low cost, and fast heating.

[0051] The bottom of the food waste bin 2 is provided with a downwardly extending latching part 27, and the drive assembly 4 is provided with a locking groove 43 that cooperates and is fixed with the latching part 27. By connecting the latching part and the locking groove, the food waste bin can be quickly fixed on the drive assembly, which can prevent the food waste from rotating and causing the food waste bin to shift when the stirring blades are stirring the food waste. It has the advantages of simple and reasonable structure, low manufacturing cost, and convenient assembly, disassembly and cleaning. Furthermore, the latching part can be adopted in an axisymmetric manner to improve the overall balance and stability of the food waste bin.

[0052] The implementation method of this embodiment is as follows:

[0053] The connecting bushing 5 is made of resin. The first connecting cavity 511 has a plurality of spaced connecting grooves 512. The outer side of the second connecting bushing 52 has a plurality of spaced engaging parts 521 that mate with the connecting grooves 512. The number of connecting grooves 512 is greater than the number of engaging parts 521. The connecting grooves 512 are arc-shaped, and the engaging parts 521 are arc-shaped.

[0054] The first connecting sleeve 51 has a first connecting sleeve opening 513 that is smaller than the top outer diameter of the screw 6. The screw 6 passes through one side of the first connecting sleeve opening 513 to the other side of the first connecting sleeve opening 513 and connects with the threaded cavity on the connecting shaft 32. The screw 6 connects with the threaded cavity, so that the first connecting sleeve 51 and the connecting shaft 32 are tightly connected.

[0055] The food waste bin 2 is detachably mounted on the drive assembly 4. Since there is a connecting bushing 5 between the stirring blade 3 and the drive assembly 4, the stirring blade 3 is connected to the first connecting bushing 51, and the drive assembly 4 is connected to the second connecting bushing 52. The first connecting bushing 51 is sleeved on the outside of the second connecting bushing 52. When the food waste bin 2 is detached from the drive assembly 4 for emptying and cleaning, the food waste bin 2 drives the stirring blade 3 in the stirring chamber 21, and drives the connecting groove 512 on the first connecting bushing 51 to separate from the engaging part 521 on the second connecting bushing 52.

[0056] When the food waste bin 2 is connected to the drive assembly 4, since the number of connecting grooves 512 is greater than the number of engaging parts 521, and both the connecting grooves 512 and the engaging parts 521 are arc-shaped, the first connecting sleeve 51 and the second connecting sleeve 52 form an automatic alignment connection. The first connecting sleeve 51 is quickly fitted onto the outside of the second connecting sleeve 52, and the first connecting sleeve 51 and the second connecting sleeve 52 engage to form a stable structure.

[0057] When the drive assembly 4 is powered on, the drive shaft 41 on the drive assembly 4 drives the second connecting sleeve 52 to rotate through the cooperation of the second connecting groove 523. The second connecting sleeve 52 is connected to the connecting groove 512 through the engaging part 521, driving the first connecting sleeve 51 to rotate. When the first connecting sleeve 51 rotates, the first connecting groove 54 drives the engaging end 322 to rotate simultaneously. Through the cooperation between the engaging end 322 and the first connecting groove 54, the connecting shaft 32 connected to the first connecting sleeve 51 is driven to rotate. The rotation of the connecting shaft 32 drives the stirring blade 3 to stir in the stirring chamber 21. The stirring blade 3 cuts the kitchen waste into smaller fragments. The setting of the connecting sleeve 5 ensures the transmission efficiency and transmission stability of the kitchen waste collector. Compared with traditional technology, it is not necessary to align the teeth and the tooth grooves in sequence, which can greatly improve the convenience of connection and avoid the situation where the first connecting sleeve 51 and the second connecting sleeve 52 are easily misaligned when connected, causing damage to the connecting sleeve 5 during operation.

[0058] The connecting shaft 32 is non-removably installed on the mounting cavity 31 by die casting. The connecting shaft 32 is located inside the mounting cavity 31. The first connecting shaft sleeve 51 extends from the outside of the second opening 24 to the inside of the second opening 24 and is connected to the connecting shaft 32 that passes through the first opening 23 on the mounting platform 22.

[0059] The mounting platform 22 is provided with a first step 221 and a second step 222. The shaft seal is located between the lower side of the first opening 23 and the upper side of the first step 221, which can prevent the shaft seal from moving up and down. The shaft seal can further block steam and liquid from entering the mounting platform from the mounting cavity, ensuring the connection stability between the stirring blade and the drive assembly.

[0060] One end of the first bearing 81 is engaged on the first step 221 and the other end extends toward the second step 222. One end of the second bearing 82 is engaged on the second step 222 and the other end extends toward the first step 221. The bearing 8 can further fix the connecting shaft 32, improve the stability of the connecting shaft 32 when rotating, and avoid the phenomenon of displacement due to vibration when the connecting shaft 32 rotates. The bearing 8 is made of composite material, and graphene lubrication layers are provided on the inner and outer sides of the bearing 8, which can reduce the wear between the bearing 8 and the connecting shaft 32, as well as between the bearing 8 and the mounting platform 22.

[0061] By providing a first seal 72 between the outer side of the first opening 23 and the connecting shaft step 321, solids, gases or liquids can be prevented from entering the inner side of the mounting platform 22 from the mounting cavity 31, ensuring the connection stability between the stirring blade 3 and the drive assembly 4. Two first seals 72 are provided and stacked, and one of the first seals 72 can completely cover the upper side of the first opening 23.

[0062] The gasket 323 is placed between the connecting shaft 32 and the first connecting bushing 51 to reduce wear caused by collision between the connecting shaft 32 and the connecting bushing 5, and at the same time, it can reduce energy loss during transmission and improve transmission efficiency.

[0063] Users place kitchen waste generated in the kitchen waste bin 2, set the processing time and temperature, and turn on the power. When the drive assembly 4 is powered on, the drive shaft 41 on the drive assembly 4 drives the second connecting sleeve 52 to rotate. The second connecting sleeve 52, through a mutually engaging engagement structure, drives the first connecting sleeve 51 to rotate. When the first connecting sleeve 51 rotates, the first connecting groove 54 drives the engaging end 322 to rotate simultaneously. Through the engagement of the engaging end 322 and the first connecting groove 54, the connecting shaft 32 connected to the first connecting sleeve 51 is driven to rotate. The rotation of the connecting shaft 32 drives the stirring blade 3 to stir within the stirring chamber 21. This connection method reduces energy loss during transmission, thereby increasing the torque of the stirring blade 3. The stirring blade 3 can thoroughly cut the kitchen waste and effectively convert large or hard kitchen waste into smaller fragments, preventing uncut kitchen waste from getting stuck on the stirring blade 3 and preventing it from operating normally. The design of the connecting shaft 32 effectively improves the processing efficiency of the kitchen waste processor and can further meet the needs of customers.

[0064] Meanwhile, contact 9212 is connected to conductive part 42, and current is transferred to heating wire 911 through connecting core rod 9211. Heating wire 911 starts to heat up after being energized and continuously transfers heat to food waste bin 2. The temperature of food waste bin 2 is transferred from the bottom to food waste bin connecting part 25. Food waste bin connecting part 25 is connected to temperature sensor 10. Temperature sensor 10 can detect the temperature of food waste bin 2. According to the set temperature, temperature sensor 10 controls the start and stop of heating component 9 to accurately control the temperature of food waste bin 2. Heating component 9 is fixed by annular structure fixing groove 261, so that the heat of heating component 9 is better transferred upward and the heat transfer efficiency is improved. After the heating component 9 evaporates the moisture of food waste in food waste bin 2, it can reduce the generation of leachate. Stirring turns food waste into powder.

[0065] After heating is complete, lift the food waste bin 2. The buckle 27 of the food waste bin 2 separates from the slot 43 on the drive assembly 4. The stirring blade 3 inside the food waste bin 2 separates from the second connecting bushing 52 through the first connecting bushing 51. The contact 9212 of the food waste bin 2 separates from the conductive part 42. The food waste bin connecting part 25 on the food waste bin 2 separates from the temperature sensor 10 on the drive assembly 4. Pour out the processed food waste in the food waste bin 2 and clean the food waste bin 2. The processed food waste is easily absorbed by green plants and can be used as organic fertilizer for planting green plants, so that the processed food waste can be reused.

[0066] After cleaning, the buckle 27 of the food waste bin 2 is connected to the slot 43 on the drive assembly 4, the stirring blade 3 inside the food waste bin 2 is connected to the second connecting sleeve 52 through the first connecting sleeve 51, the food waste bin connecting part 25 on the food waste bin 2 is connected to the temperature sensor 10 on the drive assembly 4, and the contact 9212 of the food waste bin 2 is connected to the conductive part 42 for the next use.
