The drawbacks of this prior art are that it has a poor shredding effect, requires manual transfer of the garbage, is inconvenient to use, and does not have a garbage drying function, making it inconvenient to store or compost wet garbage.

[0003] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0004] In order to solve the problems of the prior art, the present invention provides a kitchen waste treatment mechanism, which has higher working efficiency, is more convenient to use, and has a garbage drying function, which is convenient for dry garbage storage or composting.

[0005] In order to achieve the above object, the technical solutions applied by the present invention are as follows:

[0006] A kitchen waste treatment mechanism comprises a main unit, wherein a driving device is provided in the main unit; a trash can, which is detachably installed in the main unit, and is provided with a feed port and a discharge port. An inner cavity is formed in the trash can, and a spiral rod and a bar-shaped fixed knife are provided in the inner cavity. The spiral rod is driven to rotate forward and reverse by the driving device. When the spiral rod rotates forward, it is used to cooperate with the bar-shaped fixed knife to compress and crush the garbage. When the spiral rod rotates backward, it is used to transport the crushed garbage to the discharge port. A storage box for storage or composting is correspondingly provided at the discharge port; a drying device, wherein the drying device is used to dry the garbage in the inner cavity. The drying device comprises a heating component and an air duct component. With this arrangement, kitchen waste is put into the trash can through the feed port, and the driving device drives the screw rod to rotate in the forward direction, and the screw rod cooperates with the bar-shaped fixed knife to compress and crush the waste, which has higher working efficiency; at the same time, the drying device is used to dry the waste in the inner cavity to turn it into dry waste; after the crushing is completed, the driving device drives the screw rod to rotate in the reverse direction, and the screw rod is used to transfer the crushed waste to the discharge port and then stored in the storage box. The dry waste is convenient for storage or composting and is more convenient to use.

[0007] According to the above scheme, the trash can includes a drying box, a discharge port located on the drying box, and a valve movably provided at the discharge port. The valve is driven to open or close the discharge port by a door-opening motor unit. A top cover movably provided on the main unit is used to open or close the feed port. The heating assembly includes a heating element 1 provided on the drying box and a heating element 2 provided on the top cover. With this arrangement, kitchen waste is placed into the trash can through the feed port, the top cover closes the feed port, and the valve closes the discharge port, sealing the interior of the trash can. The waste in the interior is dried by the dual heating action of heating element 1 and heating element 2, and the rotation of the spiral rod simultaneously dries the waste quickly.

[0008] According to the above scheme, the air duct assembly includes a fan, an air inlet duct, an air outlet duct, air duct one and air duct two. The fan, air inlet duct and air outlet duct are arranged in the main unit, air duct one and air duct two are arranged on the upper cover, the fan is connected to the air inlet duct, the air inlet duct is connected to air duct one, air duct one is connected to the inner cavity of the trash can, the inner cavity of the trash can is connected to air duct two, air duct two is connected to the air outlet duct, and the heating element two is located in air duct one. This arrangement has two modes. One is the mode when the heating element 2 is working. When the fan is working, the external cold air is drawn in, and enters the air duct one after passing through the air inlet duct. The heating element 2 is heated to form hot air, and then enters the inner cavity of the trash can, which can quickly dry the garbage in the inner cavity and discharge the generated steam through the air outlet duct; the other is the mode when the heating element 2 is not working. When the fan is working, the external cold air is drawn in, and enters the air duct one after passing through the air inlet duct, and then enters the inner cavity of the trash can. After heat exchange, it is discharged through the air outlet duct, so that the evaporated water is discharged through the air outlet duct.

[0009] According to the above solution, the air duct is provided with a first inlet and a first outlet at both ends. The first inlet is connected to the air inlet duct, and the first outlet is connected to the inner cavity of the trash can. The air duct is provided with a second inlet and a second outlet at both ends. The second inlet is connected to the inner cavity of the trash can, and the second outlet is connected to the air outlet duct. The first outlet is arranged in a ring shape, and there are multiple second inlets distributed around the first outlet. This arrangement allows the airflow to enter the inner cavity of the trash can through the ring-shaped first outlet, distributing the heat more evenly. Combined with the multiple second inlets, the airflow forms a vortex flow, which improves the drying effect.

[0010] According to the above solution, the air outlet duct is equipped with a deodorization and purification component, which includes a heater, a metal catalyst, a photocatalyst, and activated carbon. This arrangement ensures that the exhaust gas is odorless and harmless. When the fan is started, the wind pressure drives external cold air into the inner cavity of the trash can. After heat exchange, the hot air is pushed into the air outlet duct. The heater is heated to 130 degrees Celsius (+ / - 10 degrees), and the metal catalyst's deodorization capacity is at its best at this high temperature. The gas passing through this area is purified to the maximum extent and pushed to the photocatalyst space. The photocatalyst then performs a secondary sterilization and deodorization purification, and pushes it to the activated carbon space. The activated carbon then performs a third adsorption purification of the gas, and the gas discharged from the machine is finally odorless and harmless.

[0011] According to the above solution, the spiral rod includes a rotating shaft and spiral blades fixed to the rotating shaft. The rotating shaft extends out of the trash can and is connected to the driving device 1. The spiral blades include alternating crushing spiral blades and stirring spiral blades. The outer edges of the crushing spiral blades are formed with crushing blades, the stirring spiral blades are formed with stirring grooves, and stirring blocks are formed between the crushing spiral blades and the stirring spiral blades. With this arrangement, when the driving device 1 drives the spiral rod to rotate forward, the surfaces of the crushing spiral blades and the stirring spiral blades cooperate to compress the garbage, wherein the crushing blades of the crushing spiral blades are used to crush the garbage, and the stirring grooves and stirring blocks on the stirring spiral blades are used to stir the garbage. After crushing, the driving device 1 drives the spiral rod to rotate in the reverse direction, and the surfaces of the crushing spiral blades and the stirring spiral blades cooperate to transport the garbage.

The transmission shaft is retractably provided on the coupling, and the transmission shaft is used to be connected to the corresponding rotating shaft. The retraction drive member is used to drive the transmission shaft to retract into the coupling, and the extension drive member is used to drive the transmission shaft to extend out of the coupling. The trash can is provided with a toggle member corresponding to the extension drive member. With this arrangement, when the drive gear set is in operation, the drive coupling drives the screw to rotate. In the initial state, the transmission shaft is in a retracted state, avoiding the assembly space of the trash can. When the trash can is assembled, the toggle member toggle the extension drive member, and the extension drive member drives the transmission shaft to extend and connect with the screw rod. Manual alignment is eliminated, making the trash can assembly convenient. When the trash can is disassembled for cleaning, the retraction drive member drives the transmission shaft to retract into the coupling, and the transmission shaft is disengaged from the screw rod, allowing the trash can to be removed.

[0013] According to the above scheme, the door opening motor group includes a shell, a rack and a cover body.

The output end of the servo motor is drivingly connected to the drive wheel, which is meshed with the transmission gear set, which is meshed with the rack. With this arrangement, when the servo motor is operating, the drive wheel drives the transmission gear set to rotate, which in turn drives the rack and the valve to slide, thereby opening or closing the discharge port.

[0015] According to the above solution, a guide slot is formed on the rack, and a guide rail is provided on the housing and the cover, and the guide rail and the guide slot are arranged in coordination. This arrangement enables the rack to slide horizontally along the guide rail when sliding.

With this arrangement, kitchen waste is put into the trash can 3 through the feed port 17, and the driving device drives the screw rod 13 to rotate forward, and the screw rod 13 cooperates with the bar-shaped fixed knife 14 to compress and crush the waste, which has higher working efficiency; at the same time, the drying device is used to dry the waste in the inner cavity to turn it into dry waste; after the crushing is completed, the driving device drives the screw rod 13 to rotate in the opposite direction, and the screw rod 13 is used to transfer the crushed waste to the discharge port 18, and then stored in the storage box 4. The dry waste is convenient to store or compost, and is more convenient to use.

[0035] In actual application, there are two groups of the strip-shaped fixed knives 14 , which are symmetrically fixed on the inner wall of the trash can 3 , and the spiral rod 13 is located between the two groups of the strip-shaped fixed knives 14 .

[0036] Furthermore, the trash can 3 includes a drying box 12, a discharge port 18 is located on the drying box 12, and the discharge port 18 is movably provided with a valve 16, which is driven by a door opening motor unit 15 to open or close the discharge port 18. The main unit 1 is movably provided with an upper cover 2, which is used to open or close the feed port 17. The heating assembly includes a heating element 19 provided on the drying box 12 and a heating element 2 provided on the upper cover 2. With this arrangement, kitchen waste is put into the trash can 3 through the feed port 17, the upper cover 2 closes the feed port 17, and the valve 16 closes the discharge port 18, so that the inner cavity of the trash can 3 is in a closed state. Under the dual heating action of the heating element 19 and the heating element 2, the waste in the inner cavity is dried, and at the same time, the spiral rod 13 rotates to quickly dry the waste.

[0037] In practical applications, when the feed port 17 and the discharge port 18 are closed, heat loss can be prevented, and leakage of garbage during the shredding process and overflow of garbage odor can be prevented.

[0038] Preferably, the drying box 12 is an aluminum box body with good heat conduction effect; the heating element 19 is a heating tube surrounding the bottom of the drying box 12, which heats more evenly.

[0039] Further, the air duct assembly includes a fan 7, an air inlet duct 5, an air outlet duct 6, air duct 1 21 and air duct 2 22. The fan 7, the air inlet duct 5 and the air outlet duct 6 are arranged in the main unit 1, and air duct 1 21 and air duct 2 22 are arranged on the upper cover 2. The fan 7 is connected to the air inlet duct 5, the air inlet duct 5 is connected to air duct 1 21, air duct 1 21 is connected to the inner cavity of the trash can 3, the inner cavity of the trash can 3 is connected to air duct 2 22, air duct 2 22 is connected to the air outlet duct 6, and the heating element 2 is located in air duct 1 21. With this arrangement, it has two modes. One is the mode when the heating element 2 is working. When the fan 7 is working, the external cold air is drawn in, and enters the air duct 1 21 after passing through the air inlet duct 5. The heating element 2 is heated to form hot air, and then enters the inner cavity of the trash can 3, which can quickly dry the garbage in the inner cavity and discharge the generated steam through the air outlet duct 6; the other is the mode when the heating element 2 is not working. When the fan 7 is working, the external cold air is drawn in, and enters the air duct 1 21 after passing through the air inlet duct 5, and then enters the inner cavity of the trash can 3. After heat exchange, it is discharged through the air outlet duct 6, so that the evaporated water is discharged through the air outlet duct 6.

[0040] Specifically, the first air duct 21 is provided with a first inlet 23 and a first outlet 24 at both ends. The first inlet 23 is connected to the air inlet duct 5, and the first outlet 24 is connected to the inner cavity of the trash can 3. The second air duct 22 is provided with a second inlet 25 and a second outlet 26 at both ends. The second inlet 25 is connected to the inner cavity of the trash can 3, and the second outlet 26 is connected to the air outlet duct 6. The first outlet 24 is arranged in an annular shape, and there are multiple second inlets 25 distributed around the periphery of the first outlet 24. This arrangement allows the airflow to enter the inner cavity of the trash can 3 through the annular first outlet 24, distributing the heat more evenly. Combined with the multiple second inlets 25, the airflow forms a vortex flow, which improves the drying effect.

[0041] Furthermore, the air outlet duct 6 is provided with a deodorization and purification component, which includes a heating element, a metal catalyst, a photocatalyst, and activated carbon. This configuration ensures that the exhaust gas is odorless and harmless. When the fan 3 is started, the wind pressure drives the external cold air into the inner cavity of the trash can 3. After heat exchange, the hot air is pushed into the air outlet duct 6. The heating element is heated to 130 degrees (+ / - 10). The metal catalyst's deodorization capacity is at its best at this high temperature. The gas passing through here is purified to the maximum extent and pushed to the photocatalyst space. The photocatalyst then undergoes secondary sterilization, deodorization, and purification, and pushes it to the activated carbon space. The activated carbon then undergoes three adsorption and purification processes to purify the gas, and finally the gas discharged from the machine is odorless and harmless.

[0042] Furthermore, the screw rod 13 includes a rotating shaft 51 and a spiral blade fixed to the rotating shaft 51. The rotating shaft 51 passes through the trash can 3 and is connected to the driving device 1. The spiral blades include alternating crushing spiral blades 52 and stirring spiral blades 54. The outer edge of the crushing spiral blade 52 is formed with a crushing blade 53, the stirring spiral blade 54 is formed with a stirring groove 55, and a stirring block 56 is formed between the crushing spiral blade 52 and the stirring spiral blade 54. With this arrangement, when the driving device 1 drives the screw rod 13 to rotate forward, the surfaces of the crushing spiral blade 52 and the stirring spiral blade 54 cooperate to compress the garbage, wherein the crushing blade 53 of the crushing spiral blade 52 is used to crush the garbage, and the stirring groove 55 and the stirring block 56 on the stirring spiral blade 54 are used to stir the garbage; after crushing, the driving device 1 drives the screw rod 13 to rotate in the opposite direction, and the surfaces of the crushing spiral blade 52 and the stirring spiral blade 54 cooperate to transport the garbage.

[0043] In practical applications, the crushing spiral blade 52 and the stirring spiral blade 54 can be an integrated structure or a separate structure.

[0044] Furthermore, the driving device 1 includes a driving gear set 8 and a coupling 9. The output end of the driving gear set 8 is connected to the coupling 9. The coupling 9 is provided with a transmission shaft 31, a retraction drive member 32 and an extension drive member 33. The transmission shaft 31 is retractably arranged on the coupling 9. The transmission shaft 31 is used to be connected to the rotating shaft 51. The retraction drive member 32 is used to drive the transmission shaft 31 to retract into the coupling 9. The extension drive member 33 is used to drive the transmission shaft 31 to extend out of the coupling 9. The trash can 3 is provided with a toggle member 34 corresponding to the extension drive member 33. With this arrangement, when the driving gear set 8 is working, the driving coupling 9 drives the screw rod 13 to rotate. In the initial state, the transmission shaft 31 is in a retracted state, avoiding the assembly space of the trash can 3. When the trash can 3 is assembled, the extending driving member 33 is actuated by the toggle member 34, and the extending driving member 33 drives the transmission shaft 31 to extend and connect with the screw rod 13. There is no need for manual alignment, which makes the assembly of the trash can 3 convenient. When the trash can 3 is disassembled for cleaning, the transmission shaft 31 is retracted into the coupling 9 by the retracting driving member 32, and the transmission shaft 31 is disengaged from the screw rod 13, and the trash can 3 can be taken out.

[0045] Furthermore, the door opening motor group 15 includes a shell 40, a rack 41 and a cover body 42. The cover body 42 is fixed on the shell 40. The first end of the rack 41 is slidably arranged between the cover body 42 and the shell 40. The second end of the rack 41 passes through the opening 44 of the shell 40 and is fixedly connected to the valve 16. A driving device 2 is provided on the shell 40, and the driving device 2 is driven and connected to the rack 41.

[0046] Specifically, the second drive device includes a servo motor 48, a drive wheel 49, and a transmission gear set 46. The output end of the servo motor 48 is drivingly connected to the drive wheel 49, which is meshed with the transmission gear set 46, which is meshed with the rack 41. With this arrangement, when the servo motor 48 is operating, the drive wheel 49 drives the transmission gear set 46 to rotate, which in turn drives the rack 41 and the valve 16 to slide, thereby opening or closing the discharge port 22.

[0047] In actual application, there are two groups of racks 41 symmetrically arranged at both ends of the housing 40. The servo motor 48 drives the two groups of racks 41 to move simultaneously through the linkage shaft 47, so that the valve 16 can move more evenly and stably.

[0048] Furthermore, a guide slot 45 is formed on the rack 41, and a guide rail 43 is provided on the housing 40 and the cover 42. The guide rail 43 and the guide slot 45 are matched with each other. In this way, the rack 41 slides horizontally along the guide rail 43 when sliding.

[0049] Of course, the positions of the guide slot 45 and the guide rail 43 can also be interchanged, that is, the guide slot 45 is set on the shell 40 and the cover 42, and the guide rail 43 is set on the rack 41 to achieve the same effect.
