Description

Technical Field

[0002] With the acceleration of urbanization and the improvement of people's living standards, green plant maintenance is becoming increasingly important in homes, offices, and public spaces. However, traditional green plant maintenance methods often rely on manual management and experience-based judgment. This approach is not only inefficient but also easily affected by human negligence or environmental changes, impacting plant growth. For example, overwatering or underwatering can damage plants; insufficient light can prevent plants from carrying out effective photosynthesis.

[0003] While some plant care systems exist, their functions are relatively limited. For example, they might turn on supplemental lighting when the ambient light level falls below a certain threshold. However, different plants have different care requirements, making these systems ill-suited to the diverse needs of different species. Consequently, they are less adaptable and have higher energy costs. Utility Model Content

[0046] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0050] Existing plant care systems generally have limited functions, such as turning on maintenance lights to supplement light when the ambient light level falls below a certain threshold. However, different plants have different care characteristics, making it difficult for such systems to adapt to the needs of different plant species, resulting in poor adaptability. Furthermore, these systems have high power consumption costs.

[0051] This utility model proposes a green plant maintenance circuit.

[0052] Please see Figure 1 In one embodiment of this utility model, the plant maintenance circuit is applied to a plant maintenance system, which includes a water pump MT and a water tank. The plant maintenance circuit includes:

[0053] Wireless receiving circuit 01 is used to receive wireless control signals;

[0054] Maintenance lamp circuit 02 is used to provide a light source;

[0055] Water pump drive circuit 03 is connected to water pump MT;

[0056] The light intensity detection circuit 04 is used to detect the light intensity of the environment where the green plants are located and output the corresponding light intensity detection signal.

[0057] Touch water detection circuit 05, the touch water detection terminal TH of touch water detection circuit 05 is set inside the water tank, touch water detection circuit 05 is used to detect the water level of the water source in the water tank and output the corresponding water detection signal.

[0058] The solar power supply circuit 06 has its power output terminal connected to the power terminals of the wireless receiving circuit 01, the maintenance lamp circuit 02, the water pump drive circuit 03, and the light intensity detection circuit 04, respectively. The solar power supply circuit 06 is used to convert light energy into electrical energy and provide power supply voltage.

[0059] Control circuit 07 is connected to the signal output terminal of wireless receiving circuit 01, the signal output terminal of light intensity detection circuit 04, the signal output terminal of touch water detection circuit 05, the controlled terminal of maintenance lamp circuit 02, the controlled terminal of water pump drive circuit 03, and the power output terminal of solar power supply circuit 06.

[0060] The control circuit 07 is used to control the operation of the maintenance lamp circuit 02 according to the wireless control signal and the light intensity detection signal, and to control the operation of the water pump drive circuit 03 according to the wireless control signal and the water detection signal.

[0061] In one feasible implementation, please refer to Figure 11 The control circuit 07 may include a main control chip U6, a push-button switch K, an LED DA, an eleventh capacitor, and a twenty-second resistor. The push-button switch K is used for powering on / off, and the LED DA serves as an indicator light to display information.

[0062] It should be noted that the wireless control signal is used to adjust parameters such as preset light intensity threshold, preset watering frequency, and preset watering amount. Users can connect to the wireless receiving circuit 01 via wireless devices (such as smartphones, tablets, or dedicated remote controls). Users can set specific preset light intensity thresholds for each type of plant. For example, for shade-loving plants, users can set a lower preset light intensity threshold; when the ambient light intensity exceeds this preset value, the system will automatically turn off the maintenance light. For plants that require more light, users can set a higher threshold; the light source will only be turned on when the ambient light intensity is below this threshold. The control circuit 07 compares the preset light intensity threshold with the ambient light intensity detected by the light intensity detection circuit 04, and adjusts the working state of the LEDs in the maintenance light circuit 02 according to the comparison result to ensure that different plants receive suitable lighting conditions. Similarly, users can set personalized watering plans for different types of plants, including timed and quantitative watering frequencies and the amount of water each time. For drought-tolerant plants, users can extend the watering interval and reduce the amount of water each time; conversely, for plants with high water requirements, the watering interval can be shortened and the amount of water each time increased. The touch-sensitive water level detection circuit 05 continuously monitors the water level in the tank and, in conjunction with the water pump drive circuit 03, drives the water pump MT to execute the user's settings. If the water level in the tank is insufficient, the control circuit 07 can also control the indicator light to flash to notify the user to replenish the water.

[0063] It should be noted that the plants can be kept indoors for maintenance. Components such as the wireless receiving circuit 01, maintenance light circuit 02, water pump drive circuit 03, light intensity detection circuit 04, control circuit 07, water pump MT, and water tank can be placed close to the plants. The solar power supply circuit 06 can include energy storage devices such as solar panels SP and batteries BAT. The solar panels SP can be placed outdoors in areas with ample sunlight, where sunlight is usually sufficient during the day. The solar panels SP can convert solar energy into electrical energy and store it in the batteries BAT. The batteries BAT can then power the wireless receiving circuit 01, maintenance light circuit 02, water pump drive circuit 03, light intensity detection circuit 04, and control circuit 07. This fully utilizes solar energy, eliminating the need to obtain power from the external power grid and incurring additional electricity costs, thus saving on plant maintenance costs.

[0064] In this embodiment, the wireless receiving circuit 01 can receive wireless control signals, which can be used to adjust parameters such as preset light intensity threshold, preset watering frequency, and preset watering amount. The light intensity detection circuit 04 can detect the light intensity of the environment where the green plants are located and output a corresponding light intensity detection signal. When the control circuit 07 determines that the ambient light intensity is less than the preset light intensity threshold based on the light intensity detection signal, it controls the maintenance lamp circuit 02 to work to provide a light source; when the ambient light intensity reaches the preset light intensity threshold, it controls the maintenance lamp circuit 02 to stop working. The touch water detection circuit 05 can detect the water level in the water tank and output a corresponding water detection signal. When the control circuit 07 determines that the water tank has sufficient water based on the water detection signal, it controls the water pump drive circuit 03 to work according to parameters such as preset watering frequency and preset watering amount to water the green plants on time and in the correct amount. The solar power supply circuit 06 can convert light energy into electrical energy and provide the electrical energy required for the operation of each circuit. Thus, this embodiment can adapt to the maintenance needs of different types of green plants without consuming additional power from the external power grid, which can solve the problems of poor adaptability and high power consumption costs of existing green plant maintenance systems.

[0065] In this invention, the wireless receiving circuit 01 can receive wireless control signals, which can be used to adjust parameters such as preset light intensity threshold, preset watering frequency, and preset watering amount. The light intensity detection circuit 04 can detect the light intensity of the environment where the green plants are located and output a corresponding light intensity detection signal. When the light intensity of the environment is less than the preset light intensity threshold based on the light intensity detection signal, the control circuit 07 controls the maintenance lamp circuit 02 to work to provide a light source; when the light intensity reaches the preset light intensity threshold, the control circuit 07 controls the maintenance lamp circuit 02 to stop working. The touch water detection circuit 05 can detect the water level in the water tank and output a corresponding water detection signal. When the control circuit 07 determines that the water tank has sufficient water based on the water detection signal, it controls the water pump drive circuit 03 to work according to parameters such as preset watering frequency and preset watering amount to water the green plants on time and in the correct amount. The solar power supply circuit 06 can convert light energy into electrical energy and provide the electrical energy required for the operation of each circuit. Thus, this invention can adapt to the maintenance needs of different types of green plants without consuming additional power from the external power grid, thus solving the problems of poor adaptability and high power consumption costs of existing green plant maintenance systems.

[0066] Please see Figure 2 In one embodiment of this utility model, the solar power supply circuit 06 includes a solar panel SP, a first resistor R1, a second resistor R2, a third resistor R3, a first diode D1, a first capacitor C1, a battery BAT, and a battery protection chip U1.

[0067] Specifically, the first power output terminal of the solar panel SP and one end of the second resistor R2 are connected to the positive terminal of the first diode D1. The second power output terminal of the solar panel SP and one end of the third resistor R3 are grounded. The other end of the third resistor R3 and the other end of the second resistor R2 are connected to the first signal input terminal of the control circuit 07. The negative terminal of the first diode D1 and the positive terminal of the battery BAT are connected to one end of the first resistor R1. The other end of the first resistor R1 and one end of the first capacitor C1 are connected to the VDD pin of the battery protection chip U1. The negative terminal of the battery BAT and the other end of the first capacitor C1 are connected to the GND pin of the battery protection chip U1. The VM1 pin and VM2 pin of the battery protection chip U1 are grounded.

[0068] It should be noted that the battery protection chip U1 integrates multiple circuits, including a MOSFET switching circuit, a high-precision voltage detection circuit, and a delay circuit, thereby providing protection against over-discharge, overcharge, overcurrent, and short circuits. For example, when the battery voltage is below 2.4V or above 4.2V, the MOSFET inside the chip automatically disconnects the circuit between the battery BAT (BAT-) and ground (GND), thus stopping the charging and discharging process and protecting the battery BAT from damage. Furthermore, an over-discharge protection point (e.g., 2.7V) can be set to ensure that the battery BAT is not over-discharged, thereby extending its lifespan. When the battery voltage drops below 2.7V, the automatic control system enters a low-power standby sleep state until the solar panel SP charges the battery voltage back to 2.9V, at which point the control system resumes normal operation. To avoid frequent state switching of the battery voltage due to the "pull-out" effect in a short period, a buffer mechanism can be designed: when the battery voltage is below 2.7V, the battery BAT will be charged by the solar panel SP during the day, ensuring that the battery BAT charge gradually recovers to a safe level, and then resumes operation after a full day. This helps avoid repeated start-stop cycles of the battery (BAT) due to voltage fluctuations, while keeping the battery BAT in a healthier state, thus effectively extending its lifespan. Therefore, this embodiment can effectively support the long-term stable operation of the plant care circuit while ensuring the safety of the battery BAT.

[0069] It should be noted that control circuit 07 can detect the voltage value of solar panel SP in real time through the voltage division effect of the second resistor R2 and the third resistor R3. For example, when the voltage of solar panel SP exceeds 1V, control circuit 07 illuminates the indicator light, indicating that solar panel SP is working normally and has charging capability. If the voltage of solar panel SP is greater than the battery voltage at this time, the charging process is automatically started to charge battery BAT. Conversely, when the voltage of solar panel SP is lower than 0.4V, control circuit 07 turns off the indicator light, indicating that solar panel SP currently does not have charging capability. Users can determine whether solar panel SP has charging capability by observing the status of the indicator light. If the indicator light is off during the day, users can infer that solar panel SP does not receive enough sunlight, possibly due to improper solar panel placement or shading. In this case, users can adjust the position of solar panel SP in time to ensure that it receives sufficient sunlight and resumes normal operation.

[0070] Please see Figure 3 In one embodiment of this utility model, the light intensity detection circuit 04 includes a fourth resistor R4, a phototube CDS, and a second capacitor C2;

[0071] The first end of the phototube CDS is connected to the power supply terminal of the light intensity detection circuit 04. The second end of the phototube CDS, one end of the second capacitor C2, and one end of the fourth resistor R4 are connected to the second signal input terminal of the control circuit 07. The other end of the second capacitor C2 and the other end of the fourth resistor R4 are grounded.

[0072] It should be noted that when the ambient light intensity changes, the resistance of the phototransistor CDS also changes accordingly, resulting in a change in the current flowing through it. Consequently, the voltage detected at the second signal input terminal of the control circuit 07 will also change accordingly. The second capacitor C2 can be used for filtering. Thus, this embodiment can detect ambient light intensity relatively accurately.

[0073] Please see Figure 4 In one embodiment of this utility model, the water pump drive circuit 03 includes a fifth resistor R5, a sixth resistor R6, a first switch Q1, a second diode D2, and a third capacitor C3.

[0074] Among them, one end of the fifth resistor R5 is connected to the first signal output terminal of the control circuit 07, the other end of the fifth resistor R5 and one end of the sixth resistor R6 are connected to the controlled terminal of the first switch Q1, the other end of the sixth resistor R6 is grounded to the first terminal of the first switch Q1, the second terminal of the first switch Q1, one end of the third capacitor C3 and the positive terminal of the second diode D2 are connected to the first power supply terminal of the water pump MT, and the other end of the third capacitor C3, the negative terminal of the second diode D2 and the second power supply terminal of the water pump MT are connected to the power supply terminal of the water pump drive circuit 03.

[0075] In this embodiment, the first switching transistor Q1 can be a first NMOS transistor. The control circuit 07 can control the gate voltage output to the first NMOS transistor to control its conduction and cutoff, thereby controlling the operation of the water pump MT. The second diode D2 can prevent damage from reverse voltage, and the third capacitor C3 can be used for filtering and voltage regulation to ensure the stable operation of the water pump MT. It should be noted that the water pump MT can include an inlet, an outlet, a pump body, an impeller, and a motor. The inlet is connected to the water tank pipe through an inlet pipe, and the impeller is fixed on the motor shaft, rotating to drive the water flow. The water pump drive circuit 03 can be connected to the motor of the water pump MT to drive the rotation of the motor. The control circuit 07 can output PWM signals with different duty cycles to the water pump drive circuit 03, and the water pump drive circuit 03 outputs drive current to the motor of the water pump MT, causing the motor to rotate and drive the impeller to rotate.

[0076] Please see Figure 5 In one embodiment of this utility model, the maintenance lamp circuit 02 includes a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a second switch Q2, and a lamp LED.

[0077] Among them, one end of the seventh resistor R7 is connected to the second signal output terminal of the control circuit 07, the other end of the seventh resistor R7 and one end of the eighth resistor R8 are connected to the controlled terminal of the second switch Q2, the other end of the eighth resistor R8 is grounded to the first terminal of the second switch Q2, the second terminal of the second switch Q2 is connected to one end of the ninth resistor R9, the other end of the ninth resistor R9 is connected to the first power supply terminal of the lamp LED, and the second power supply terminal of the lamp LED is connected to the power supply terminal of the maintenance lamp circuit 02.

[0078] In this embodiment, the second switch Q2 can be a second NMOS transistor. The control circuit 07 can control the conduction and cutoff of the second NMOS transistor by controlling the gate voltage output to the second NMOS transistor, thereby controlling the lighting / extinguishing of the LED.

[0079] Please see Figure 6 In one embodiment of this utility model, the touch water detection circuit 05 includes a touch water detection terminal TH, a tenth resistor R10, a fourth capacitor C4 and a water level detection chip U2.

[0080] Among them, the touch water detection terminal TH is connected to one end of the tenth resistor R10, the other end of the tenth resistor R10 and one end of the fourth capacitor C4 are connected to the TCH pin of the water level detection chip U2, the other end of the fourth capacitor C4 is grounded, and the OUT pin of the water level detection chip U2 is connected to the third signal input terminal of the control circuit 07.

[0081] In this embodiment, the water level detection chip U2 can detect the water level in the tank based on the voltage change at the touch-sensitive end TH, and output a corresponding detection signal to the control circuit 07. Water exhibits different conductivities and capacitances in an electric field, thus the water level change can be detected by the signal change at the touch-sensitive end TH. The control circuit 07 can determine the water level in the tank based on the detection signal to ascertain whether there is sufficient water. If there is sufficient water, a watering operation can be performed. If the water level is insufficient, an alarm can be triggered by an indicator light and a buzzer to alert the user that the water supply is low.

[0082] Please see Figure 7 In one embodiment of the present invention, the wireless receiving circuit 01 includes an infrared signal receiving chip U3, an eleventh resistor R11 and a fifth capacitor C5.

[0083] Specifically, the INT pin of the infrared signal receiver chip U3 is connected to the fourth signal input terminal of the control circuit 07, the GND pin of the infrared signal receiver chip U3 is connected to the fifth signal input terminal of the control circuit 07, the VDD pin of the infrared signal receiver chip U3 and one end of the eleventh resistor R11 are connected to one end of the fifth capacitor C5, the other end of the eleventh resistor R11 is connected to the power supply terminal of the wireless receiver circuit 01, and the other end of the fifth capacitor C5 is grounded.

[0084] In this embodiment, the infrared signal receiving chip U3 can receive coded infrared light signals emitted by the remote control. The infrared signal receiving chip U3 can then decode the received coded infrared light signals into digital signals that the control circuit 07 can understand and process, and send these signals to the control circuit 07.
