Abstract
Description
Technical Field
[0001] This invention relates to the field of environmental protection equipment technology, and in particular to a fully automated kitchen waste treatment device and method based on identity recognition. Background Technology
[0002] With the acceleration of urbanization and the increasing demands for environmental protection, the classification and treatment of kitchen waste has become an urgent problem to be solved.
[0003] Existing kitchen waste treatment equipment relies heavily on manual labor throughout the entire process and lacks an effective identity verification mechanism. This results in management blind spots and unclear responsibilities at every stage, from disposal and sorting to collection. Residents need to deliver their waste to fixed collection points at specific times, which is not only inconvenient in terms of time, but also makes it difficult to avoid mixed or incorrect disposal during the disposal process, as it relies entirely on individual self-discipline for waste sorting. This places a huge burden on the back-end sorting and processing. At the same time, traditional open-air garbage bins or simple disposal points are prone to breeding mosquitoes and producing odors, which have a continuous impact on the community's environmental sanitation. Furthermore, it is difficult for management to accurately obtain key data such as the amount of waste and the frequency of disposal.
[0004] To address the aforementioned issues, this solution equips each household with a standard trash can containing a unique RFID tag. When a user places the trash can at the equipment's workstation, the card reader automatically reads and verifies the user's authorization information. The central controller then takes over all subsequent processes. The equipment automatically receives the trash can via a transmission system, and the automatic dumping module emptys the trash. Immediately afterward, a high-pressure cleaning system thoroughly cleans the inside of the trash can. The dumped trash is then transported in a sealed manner to the shredding chamber, where it is automatically shredded under the monitoring of a liquid level sensor and immediately discharged through a sewage system. All operational data is automatically recorded and uploaded, allowing management to obtain accurate household-level trash disposal data. This eliminates sorting errors and hygiene problems caused by human factors. The enclosed design prevents odor diffusion and secondary pollution, improving the overall environmental hygiene level of the community while effectively reducing the cost of subsequent manual sorting and management. Summary of the Invention
[0005] To overcome the limitations of existing food waste treatment equipment, the entire process relies heavily on manual intervention and lacks an effective identity verification mechanism. This results in management blind spots and unclear responsibilities at every stage, from disposal and sorting to collection. Residents need to deliver their waste to fixed collection points at specific times, which is not only inconvenient in terms of time, but also makes it difficult to avoid mixed or incorrect disposal during the disposal process, as it relies entirely on individual self-discipline for waste sorting. This places a huge burden on the back-end sorting and processing. At the same time, traditional open-air garbage bins or simple disposal points are prone to breeding mosquitoes and producing odors, which have a continuous impact on the community's environmental sanitation. Furthermore, management has difficulty accurately obtaining key data such as waste volume and disposal frequency.
[0006] The technical solution of the present invention is as follows: a fully automatic kitchen waste processing device based on identity recognition, comprising a processing device body, a central controller, a smart screen, a card reader, a processing system, an automatic dumping module, and a standard garbage bin.

[0008] Preferably, the automatic tilting module has a bearing inside, a motor outside the bearing, and a push rod on one side of the bearing. The main body of the processing equipment has a high-pressure pump inside, which is connected to a water supply pipe. One end of the water supply pipe is equipped with a cleaning nozzle, which is located at the opening end of the processing system. There are three cleaning nozzles. In use, the bearing supports the rotating shaft in the automatic tilting module, the motor provides power to the automatic tilting module, the push rod controls the clamping, positioning, or assisted tilting of the garbage can, and the high-pressure pump pressurizes ordinary tap water and delivers it to the cleaning nozzle through the water supply pipe.

In use, the crushing chamber provides a place for garbage crushing and processing, the crusher crushes the garbage fed into the crushing chamber, the sewage system transports the sewage in the garbage inside the crushing chamber, the sewage pump provides the pumping power for the sewage system, and the liquid level sensor detects the amount of sewage in the sewage system.
[0010] Preferably, a transmission system is provided on one side of the main body of the processing equipment, a toothed belt is provided on one side of the transmission system, and a pulley is provided on the outer side of the toothed belt.
[0011] As a preferred option, smart screens include: Display screen: Used to display operating instructions, advertisements, environmental protection knowledge, and other information.
[0012] Image capture camera: Used for taking pictures, recording behavior, or visual interaction with users.
[0013] AI voice module: Equipped with a speaker and microphone, it is used for voice greetings, operation prompts, playing advertisements, and receiving simple voice commands.
[0014] As a preferred option, the smart screen serves as the core human-machine interface for the device. When a user approaches the device with a standard trash can, the smart screen automatically wakes up, displaying a welcome screen and concise operation instructions, such as "Please place the trash can in the sensing area." Subsequently, after the card reader recognizes the label information inside the can, the screen dynamically displays the user's household identification, the processing progress bar, and environmental reminders, enhancing the transparency of the interaction and the user's sense of participation. During the processing, the smart screen can play animations of each stage of waste processing in real time, and provide synchronized status prompts with AI voice, such as "Cleaning in progress, please wait." In addition, the smart screen also supports touch interaction, allowing users to check processing records, points details, or learn about waste sorting through interface buttons. When the device is idle, the screen automatically switches to environmental protection promotional videos, community notifications, or advertising playback modes. After processing is completed, the screen clearly displays "Processing complete, please retrieve your trash can" accompanied by a voice reminder.
[0015] Preferably, the reader is an RFID reader / writer. When a user places a standard trash can at the initial workstation of the equipment, the reader immediately enters working mode, and its built-in antenna continuously emits radio frequency signals of a specific frequency, forming an electromagnetic field coverage area. Once a trash can with a built-in passive RFID electronic tag enters this area, the tag coil obtains energy through electromagnetic induction and is activated, wirelessly sending the unique barcode and associated household serial number stored inside to the reader. The reader receives and demodulates the signal, transmitting the digitized identity information to the central controller in real time for verification. If the information is verified, the central controller immediately sends a confirmation signal to the user through the human-machine interaction module and simultaneously starts the subsequent conveying, dumping, and processing process. If the reading fails or the information is invalid, the system can prompt the user to reposition the trash can or contact the management terminal via voice or screen.
[0016] A fully automated method for processing kitchen waste based on identity recognition includes the following steps: S11: By identifying the RFID information of the trash can, user permissions are confirmed, the system is activated, and trash can positioning and equipment self-check are completed to prepare for processing; S12: Automatically completes the dumping, high-pressure cleaning, shredding and sewage discharge of garbage, and returns the clean garbage bin to the user, while recording and uploading the processing data.
[0017] Preferably, the authentication and processing preparation phase includes the following steps: S21: The user places a standard trash can (9) with a unique RFID electronic tag in the designated initial station of the processing equipment, physically touches or approaches the sensing area of the card reader (3), triggering the equipment to wake up from standby mode, the central controller (2) is powered on, and the smart screen (201) lights up and displays a welcome interface; S22: The antenna of the card reader (3) continuously transmits radio frequency signals at a specific frequency. When the standard trash can (9) enters its electromagnetic field coverage range, the passive RFID tag inside the can is activated, wirelessly transmitting the household serial number information and can number stored inside. S23: After receiving the wireless signal returned by the RFID tag, the card reader (3) demodulates and decodes it, and sends the obtained digital user serial number information to the central controller (2) in real time through the communication line; S24: The central controller (2) verifies the validity of the received sequence number information. After successful verification, the central controller (2) generates and issues a sequence of instructions to initiate the subsequent processing flow. S25: The central controller (2) controls the smart screen (201) to update the display interface, displaying the corresponding user's home identifier and processing progress prompts. At the same time, it controls the AI voice module integrated into the smart screen (201) to broadcast a personalized greeting, completing the interaction confirmation with the user; S26: The central controller (2) sends a command to the transmission system (10), and the motor (502) in the transmission system (10) drives the pulley (102) and toothed belt (101) to smoothly transfer the standard garbage bin (9) located at the initial station to the automatic dumping module (5) station inside the equipment. At the same time, the push rod (503) in the automatic dumping module (5) is pre-activated to prepare for clamping the garbage bin. S27: During the transmission process, the central controller (2) performs a self-test on the core processing unit, including checking whether the water supply pressure of the high pressure pump (504) is normal, the status of the sewage pump (801), whether the motor circuit of the crusher (7) is unobstructed, and the initial signal of the liquid level sensor (802). After all systems are self-tested and normal, the equipment enters the waiting state.
[0018] Preferably, the automated processing and reset delivery phase includes the following steps: S31: The transmission system precisely transports the standard trash can to the preset dumping position of the automatic dumping module. Once in position, the push rod of the automatic dumping module firmly grips a specific part of the standard trash can. S32: The central controller starts the drive motor of the automatic tilting module. The motor drives the entire clamping mechanism and the standard garbage bin to tilt through the rotating shaft supported by the bearing, so that all the kitchen waste in the bin is completely poured into the inlet of the processing system below. The garbage enters the conveying pipe by gravity. S33: As the trash can is tilted and remains in its overturned position, the central controller activates the high-pressure cleaning system. The high-pressure pump starts working, pressurizing the tap water from the water supply pipe. The high-pressure water jets are sprayed in a rotating or fan-shaped pattern through multiple cleaning nozzles, thoroughly rinsing the inner wall of the inverted standard trash can. At the same time, the rinsing water jets also flush away any residual trash adhering to the walls of the conveying pipe into the downstream shredding chamber. S34: The mixture of waste and sewage washed down collects at the bottom of the pulverizing chamber. A level sensor installed on the side wall of the sewage system pipe monitors the liquid level of the mixture in real time and sends the signal back to the central controller. S35: When the liquid level sensor detects that the liquid level has reached the preset "start processing" threshold, the central controller sends a start command to the shredder. The drive motor of the shredder drives the internal cutting blades to rotate at high speed, cutting and shredding the kitchen waste in the shredding chamber and processing it into a slurry. S36: During or after the crushing operation, the central controller starts the sewage pump according to the "empty" signal from the program or the liquid level sensor. The sewage pump powerfully sucks up and discharges the crushed waste slurry in the crushing chamber through the sewage system pipes; S37: After the cleaning step reaches the preset time, the high-pressure pump stops working, the drive motor of the automatic tilting module rotates in the opposite direction, and the standard trash can that has been rinsed clean by the cleaning nozzle is smoothly flipped back to its initial upright position. Then, the clamping mechanism is released, the transmission system operates again, and the clean standard trash can is transported back to the initial work position where the user retrieved it; S38: After the trash can is reset, the central controller controls the smart screen to display the message "Processing complete, please retrieve your trash can" and triggers AI voice to broadcast it synchronously. At the same time, the system automatically generates a processing record and uploads it to the cloud management platform through the central controller's communication module. The user takes away the standard trash can, the device returns to standby mode, and the entire workflow ends.
[0019] The beneficial effects of this invention are: Existing food waste treatment equipment relies heavily on manual labor and lacks an effective identity verification mechanism. This leads to management blind spots and unclear responsibilities at every stage, from disposal and sorting to collection. Residents are required to deliver their waste to fixed collection points at specific times, which is inconvenient in terms of time. Furthermore, relying entirely on individual responsibility for waste sorting makes mixed or incorrect disposal difficult to avoid, placing a significant burden on backend sorting and processing. Traditional open-air garbage bins or makeshift disposal points are also prone to attracting insects and producing odors, causing a sustained impact on community sanitation. Moreover, management struggles to accurately obtain key data such as waste volume and disposal frequency. This solution equips each household with a standard garbage bin containing a unique RFID electronic tag. When a user places a trash can at the equipment's workstation, the card reader automatically reads and verifies their identity information. The central controller then takes over all subsequent processes. The equipment automatically receives the trash can via the transmission system, and the automatic dumping module dumps the trash. Immediately afterward, the high-pressure cleaning system thoroughly cleans the inside of the can. The dumped trash is then transported in a sealed manner to the shredding chamber, where it is automatically shredded under the monitoring of a liquid level sensor and immediately discharged through the sewage system. All operational data is automatically recorded and uploaded, allowing management to obtain accurate household-level trash disposal data. This eliminates sorting errors and hygiene problems caused by human factors. The enclosed design prevents odor diffusion and secondary pollution, improving the overall environmental hygiene level of the community while effectively reducing the cost of subsequent manual sorting and management.

At the same time, it controls the AI voice module integrated into the smart screen (201) to broadcast a personalized greeting, completing the interaction confirmation with the user; S26: The central controller (2) sends a command to the transmission system (10), and the motor (502) in the transmission system (10) drives the pulley (102) and toothed belt (101) to smoothly transfer the standard garbage bin (9) located at the initial station to the automatic dumping module (5) station inside the equipment.

After all systems are self-tested and normal, the equipment enters the waiting state.
[0034] Preferably, the automated processing and reset delivery phase includes the following steps: S31: The transmission system 10 precisely transports the standard trash can 9 to the preset dumping position of the automatic dumping module 5. Once in position, the push rod 503 of the automatic dumping module 5 firmly grips a specific part of the standard trash can 9. S32: The central controller 2 controls the start of the drive motor 502 of the automatic tilting module 5. The motor 502 drives the entire clamping mechanism and the standard garbage bin 9 to tilt through the rotating shaft supported by the bearing 501, so that all the kitchen waste in the bin is completely poured into the inlet of the processing system 4 below. The garbage enters the conveying pipe by gravity. S33: As the trash can is tilted and remains in its overturned position, the central controller 2 activates the high-pressure cleaning system. The high-pressure pump 504 starts working, pressurizing the tap water from the water supply pipe 505. The high-pressure water jet is sprayed in a rotating or fan-shaped manner through multiple cleaning nozzles 506, performing a thorough high-pressure wash on the inner wall of the inverted standard trash can 9.

Then, the clamping mechanism is released, the transmission system 10 is activated again, and the clean standard trash can 9 is transported back to the initial work position retrieved by the user. S38: After the trash can is reset, the central controller 2 controls the smart screen 201 to display the message "Processing completed, please retrieve your trash can" and triggers AI voice to broadcast it synchronously.

[0035] Example 1 To promote source separation and reduction of household waste, enhance residents' participation and experience, and achieve refined environmental management, a newly built smart community has deployed the fully automated kitchen waste treatment equipment of this invention in the underground garbage room of each residential building. This equipment replaces the traditional open kitchen waste bins and aims to provide residents with a contactless, odorless, fully automated solution for kitchen waste disposal and immediate treatment. It also establishes a traceable green points incentive system through identity binding.
[0036] Each household is equipped with a dedicated standard trash can 9, with an ultra-high frequency passive RFID electronic tag embedded in the bottom of the can. The tag contains the household's unique identification code. When residents need to dispose of kitchen waste, they simply lift their standard trash can 9, which is full of trash, to the main body of the processing equipment 1 located on the basement floor and place it on the designated initial work station on the side of the equipment. At this time, the card reader 3 located at the work station is immediately triggered. The radio frequency signal emitted by its antenna activates the RFID tag inside the standard trash can 9. The tag wirelessly transmits the encrypted household identification information back. After the card reader 3 reads and decodes the information, it sends the digital identification code to the central controller 2 located at the top of the equipment in real time via the bus.
[0037] After receiving the identity information, the central controller 2 first verifies it with the local storage or cloud database to confirm that the account is valid and in good condition. Once the verification is successful, the central controller 2 immediately issues a command to the human-computer interaction system, and the smart screen 201 next to it is lit up. The screen dynamically displays a personalized greeting of "Welcome XX Family" and a simple operation animation guide. At the same time, the AI voice module built into the smart screen 201 broadcasts a voice prompt of "Identity verification successful, processing will begin soon, please wait", completing the friendly human-computer interaction confirmation.
[0038] The automated processing flow is officially started. The central controller 2 sends a command to the transmission system 10, and the motor 502 in the transmission system 10 starts to work. Through the transmission of the pulley 102 and the toothed belt 101, the standard garbage can 9 placed at the initial station is smoothly and accurately transported laterally to the processing station inside the equipment, that is, within the grasping range of the automatic dumping module 5. At the same time, the automatic dumping module 5 is ready, and its internal push rod 503 extends out and cooperates with the mechanical structure of the module to quickly and firmly clamp the bucket handle or specific slot of the standard garbage can 9 after the garbage can is in place.
[0039] Once the central controller 2 confirms through the position sensor that the standard trash can 9 has been positioned and locked on the automatic dumping module 5, it controls the core drive motor 502 of the automatic dumping module 5 to operate. The output shaft of the motor 502 is supported by the bearing 501, which drives the entire clamping mechanism and the standard trash can 9 to rotate about 180 degrees, so that the opening of the can is facing downwards. Under the action of gravity, the kitchen waste inside the can is completely dumped into the feed inlet of the processing system 4 below, and initially slides down along the conveying pipe.
[0040] While the trash can remains inverted, the central controller 2 initiates the high-pressure cleaning process. The high-pressure pump 504 inside the equipment starts working, pumping and pressurizing tap water from the municipal water supply pipe through the water supply pipe 505. The high-pressure water flow is delivered to three cleaning nozzles 506. These rotating nozzles are aimed at the inside of the inverted standard trash can 9, spraying multiple jets of high-pressure rotating water to powerfully flush the inner wall of the can without any blind spots. This cleaning process has a dual function: first, to thoroughly clean the inner wall of the user's standard trash can 9; and second, to use the flushing water flow to flush away any residual garbage that may adhere to the walls of the conveying pipe into the shredding chamber 6 at the end of the pipe.
[0041] The mixture of waste and water washed down collects at the bottom of the shredder 6. The liquid level sensor 802, installed on the side wall of the sewage system 8, continuously monitors the liquid level in the shredder 6. When the accumulated mixture reaches the preset "processing threshold", the liquid level sensor 802 sends a signal to the central controller 2. The central controller 2 then sends a start command to the shredder 7 located at the bottom of the shredder 6. The powerful drive motor in the shredder 7 drives a set of high-strength cutting blades to rotate at high speed, cutting and grinding the kitchen waste in the shredder and crushing it into a uniform slurry mixture.
[0042] The crushing process continues for a preset time or is dynamically adjusted according to the liquid level signal to ensure that the garbage is fully crushed. Subsequently, the central controller 2 starts the sewage pump 801, a key component of the sewage system 8, according to the program settings. The sewage pump 801 operates powerfully and pumps all the processed garbage slurry in the crushing chamber 6 through the pipeline network of the sewage system 8 and discharges it into the community municipal sewage pipe network connected to it.
[0043] After the cleaning process reaches the set time, the high-pressure pump 504 automatically stops. Then, the central controller 2 controls the drive motor 502 of the automatic tilting module 5 to rotate in the opposite direction, smoothly flipping the standard trash can 9, which has been cleaned by the cleaning nozzle 506, back to its initial upright position. Next, the push rod 503 retracts, releasing the clamp on the standard trash can 9. The transmission system 10 restarts, and the toothed belt 101 transports the clean standard trash can 9 from the internal processing station back to the initial disposal station, waiting for the user to retrieve it.
[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
