It should be noted that the control module 100 at least includes a single chip microcomputer with an internal timer and an analog-to-digital converter, such as a STM8 series single chip microcomputer. The internal timer is configured to time according to actual operation needs, and the analog-to-digital converter is configured to receive an analog signal transmitted by an externally connected detection device and convert the analog signal into a digital signal, so that further control instructions may be made through determining and analyzing the digital signal by the single chip microcomputer.

It can be understood that the first control signal is a voltage signal transmitted by a pin of the single chip microcomputer. Components in the drying module 200 are activated to operate and raise a temperature to dry the kitchen waste, in a determination that the voltage signal is received by the drying module 200. Kitchen waste is usually wet, which is not conducive to be broken and other operations, so it needs to be dried during treatment.

In this embodiment, the air extraction module 300 includes at least a boosting circuit and a centrifugal fan. The boosting circuit is configured for boosting the voltage signal output by the single chip microcomputer, so that a voltage on a loop is enough to drive the centrifugal fan to rotate and extract the air generated by heating in the device. At the same time, the air extraction module 300 should further include some activated carbon for absorbing impurities and peculiar smell during the air extraction process, so as to avoid air pollution and discomfort to operators. In a specific implementation, more related components may be added according to actual needs, which is not limited by this embodiment.

The driver may be a L298N for driving motors, which is configured to drive the gear reduction motor to operate according to the third control signal, so as to drive the gear set to rotate to cause the stirring blade to rotate and grind the dried kitchen waste.
The temperature sensor 201 is configured for detecting a temperature of the drying module 200 and transmitting a temperature signal to the control module 100.
In this embodiment, the temperature sensor 201 is configured using a thermocouple. The thermocouple is a commonly used temperature measuring element in temperature measuring instruments, which directly measures temperature and converts a temperature signal into a thermoelectromotive force signal. Shapes of various thermocouples are often very different due to requirements. However, their basic structures are roughly the same. They are usually composed of hot electrodes, insulating sleeves protective tubes and junction boxes. Because they are in direct contact with measured objects, the temperature measurement is not affected by intermediate medium.
It should be noted that in the process of high-temperature drying and grinding, the temperature in the device may be too high. When the temperature in the device is higher than 120 degree Celsius, the kitchen waste is carbonized, and the carbonized kitchen waste cannot be converted into organic fertilizer, resulting in a decrease in recycling rate and waste of resources.
The control module 100 is further configured for sending a stop command to the drying module 200 in a determination that the temperature indicated by the temperature signal is higher than a preset temperature threshold, so as to suspend an operation of the drying module 200.

The drying module 200 is configured to dry the kitchen waste upon receiving the first control signal. The air extraction module 300 is configured to extract air from the kitchen waste upon receiving the second control signal. The grinding module 400 is configured to grind the kitchen waste upon receiving the third control signal. The temperature sensor 201 is configured for detecting a temperature of the drying module 200 and transmitting a temperature signal to the control module 100. The control module 100 is further configured for sending the stop command to the drying module 200 in a determination that the temperature signal is higher than the preset temperature threshold, so as to suspend an operation of the drying module 200. By adding a temperature feedback, a drying temperature of a heating plate is reduced to prevent the kitchen waste from being not recyclable because of carbonization due to overheating.

The start button 500 is configured for outputting a start signal to the control module 100 to start the control module 100 when the start button 500 is pressed.
It can be understood that the start button 500 can be connected to the control module 100 through an interface. When the start button 500 is pressed, a level signal may be sent to the control module 100, so that the control module 100 may start a circuit carried by the control module 100. The level signal may be determined as a high level or a low level according to a method of connecting the start button 500, and is not limited by the present embodiment.
The position detection device 600 is configured for transmitting a position signal to the control module 100 in a determination that the control module 100 is turned on.

The magnetoresistive sensor is based on a working principle of magnetoresistive effect, and its core part is a special metal material, a resistance value of the metal material changes with a change of external magnetic field, and the change or state of objects can be measured by the change of external magnetic field. The magnetoresistive sensor has characteristics of high precision, high sensitivity, high resolution, good stability and reliability, non-contact measurement and wide temperature range, and can be configured for dynamic and static measurement. The magnetoresistive sensor is widely used in low magnetic field measurement, angle and position measurement.
The control module 100 is further configured for determining whether the system is normally turned on according to the position signal.
In this embodiment, the position signal is configured to provide feedback for determination that a cover of the device is closed. In a determination that the cover of the device is not in a closed state, it is determined by the control module 100 that the system is not turned on normally.
Further, according to
The control module 100 is further configured for generating a fault signal in a determination that the system is not normally turned on. It could be understood that the system generates a fault signal in a determination that the feedback information of the position signal is that the cover of the device is not in a closed state.
The control module 100 is further configured for generating a display instruction according to the current working process and the fault signal. It will be understood that the display instructions contain display information for controlling an associated component to display a current state of the device.
It should be noted that when the current working process is at the drying stage, the drying module 200, the air extraction module 300 and the grinding module 400 work at the same time. When the current working process is at the grinding stage, the drying module 200, the air extraction module 300 and the grinding module 400 work at the same time. When the current working process is at the cooling stage, the air extraction module 300 and the grinding module 400 work at the same time.
Further, according to
The process indicator 700 is configured for receiving the display instructions and displaying the current working process and a fault alarm according to the display instructions.
In the present embodiment, the process indicator 700 includes three LED lamps. When the current working process is respectively at the drying stage, the grinding stage and the cooling stage, the corresponding LED lamps are illuminated. When the cover of the device is not closed, the three LED lamps flash at the same time.
In this embodiment, the start button 500 is set to start the device, the position detection device 600 is set to detect whether the device is turned on normally. Different working processes are set for a working interval, and the corresponding working processes are displayed through the process indicator 700, ensuring safety of operation of the device and facilitating users to know a working state in time.
Further, according to
The drying module 200 comprises an optocoupler U, an electric furnace filament R, a temperature-controlled switch K and an external power supply VCC2. In particular, a control terminal of the optocoupler U is connected with the control module 100 and a power supply VCC1, a controlled terminal of the optocoupler U is connected in series between an anode of the external power supply VCC2 and a first terminal of the electric furnace filament R, and the temperature-controlled switch K is connected in series between a cathode of the external power supply VCC2 and a second terminal of the electric furnace filament R.
The Optocoupler U is configured for avoiding interference between the control module 100 and the drying module 200.
It should be noted that the optocoupler U is a component electrically isolating the control terminal from the controlled terminal through photoelectric effect, so that the controlled circuit may avoid interference.
The optocoupler U is further configured for conducting according to the first control signal to control the electric furnace filament R to start heating.
In this embodiment, the optocoupler U includes a light emitting diode D and a phototransistor Q, an anode of the light emitting diode D is connected with the power supply VCC1, a cathode of the light emitting diode D is connected with the control module 100, a collector of the phototransistor Q is connected with the anode of the external power supply VCC2, and an emitter of the phototransistor Q is connected with the first terminal of the electric furnace filament R. When the cathode of the light emitting diode D receives the first control signal sent by the control module 100, the light emitting diode D is turned on, the phototransistor Q is turned on through coupling, a potential difference is generated across both ends of the electric furnace filament R, and the electric furnace filament R starts heating.
The temperature-controlled switch K is configured to be disconnected when a temperature of the electric furnace filament R exceeds a safe range, so as to avoid burning the electric furnace filament R.
It could be understood that, according to a temperature change of the working environment, the temperature-controlled switch undergoes physical deformation inside the switch, so as to disconnect a circuit where the electric furnace filament R is located when the temperature of the electric furnace filament R exceeds the safe range and protect the circuit.
The external power supply VCC2 is configured for supplying power to the drying module 200.
It should be noted that the external power supply VCC2 is not a same power supply as the power supply VCC1 used by the single chip microcomputer.
Further, according to
The crystal oscillator 102 is configured for timing so that a current working process is determined by the control module 100 according to a working time.
It should be noted that the level output terminal GPIO is connected to the cathode of the light emitting diode D of the optocoupler U.
This embodiment prevents the drying module 200 from electrical interference, and at the same time prevents the electric furnace filament R from burning, improving reliability and safety of the kitchen waste treatment system.

The boosting circuit is configured for boosting the voltage signal output by the single chip microcomputer, so that a voltage on a loop is enough to drive the centrifugal fan to rotate and extract the air generated by heating in the device. At the same time, the air extraction module should further include some activated carbon for absorbing impurities and peculiar smell during the air extraction process, so as to avoid air pollution and discomfort to operators. In a specific implementation, more related components may be added according to actual requirements, and this embodiment does not limit this.
Step S400: grinding the kitchen waste by the grinding module upon receiving the third control signal.

In this embodiment, a thermocouple is selected as the temperature sensor. The thermocouple is a commonly used temperature measuring element in temperature measuring instruments, which directly measures temperature and converts a temperature signal into a thermoelectromotive force signal. Shapes of various thermocouples are often very different due to requirements. However, their basic structures are roughly the same. They are usually composed of hot electrodes, insulating sleeves protective tubes and junction boxes. Because they are in direct contact with measured objects, the temperature measurement is not affected by intermediate medium.
It should be noted that in the process of high-temperature drying and grinding, the temperature in the device may be too high. When the temperature in the device is higher than 120 degree Celsius, the kitchen waste is carbonized, and the carbonized kitchen waste will not be converted into organic fertilizer, resulting in a decrease in recycling rate and waste of resources.
Step S600: sending, by the control module, a stop command to the drying module to make the drying module stop operating, in a determination that the temperature indicated by the temperature signal is higher than the preset temperature threshold.
