Description

Technical Field

[0001] This utility model relates to the field of lighting fixture driving technology, and more specifically, to a photosensitive timed mosquito repellent controller. Background Technology

[0002] Mosquitoes are vectors for many diseases, such as malaria, dengue fever, and Zika virus, seriously threatening human health. In daily life, people are constantly bothered by mosquito bites. Traditional mosquito repellent methods are diverse but all have obvious drawbacks. For example, while mosquito coils are inexpensive, they produce smoke particles and release harmful substances such as polycyclic aromatic hydrocarbons and formaldehyde when burned, polluting indoor air and harming the human respiratory system. Electric mosquito repellent liquids and tablets are convenient to use, but their main ingredients are pyrethroids, which may cause discomfort if used for extended periods or at high concentrations. Furthermore, their effectiveness is limited and they need to be replaced frequently.

[0003] As living standards improve, people's demands for mosquito repellent products have shifted from simply repelling mosquitoes to being intelligent and user-friendly. In bedrooms, people want mosquito repellents to automatically turn on while sleeping and turn off in the morning to avoid the potential harm of using them all night. In living rooms, people need mosquito repellents to be activated during evening activities and automatically turn off during the day when no one is around to save energy. This need for flexible mosquito control based on different scenarios and times is becoming increasingly prominent, but existing mosquito repellent technologies cannot meet the requirements for timed mosquito repellent effects. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing mosquito repellents cannot meet the requirements of timed mosquito repellency. In order to overcome the above-mentioned defects of the existing technology, this utility model provides a photosensitive timed mosquito repellent controller.

[0005] This utility model provides a photosensitive timed mosquito repellent controller, comprising:

[0006] The power supply module includes a bridge rectifier DB1 and a voltage regulator.

The collector of transistor Q2 and the voltage regulator output terminal are both electrically connected to the photoelectric input port of the main control module. The voltage regulator input terminal is electrically connected to the main control module through the relay coil terminal. The first AC input terminal of bridge rectifier DB2 is electrically connected to the live wire through the relay contact terminal, and the second AC input terminal of bridge rectifier DB2 is electrically connected to the neutral wire. The other end of each button is electrically connected to the main control module. The main control module controls the relay conduction duration based on the signal from the photoelectric input port and the signal from the button timing module.

[0011] Compared with existing technologies, the photosensitive timed mosquito repellent controller proposed in this application has the following advantages: it distinguishes between day and night through a photosensitive sensor, and at the same time, it uses a button timer module to determine the duration of nighttime activation, thus achieving autonomous timed control; it uses purple light from purple and green dual-color LED beads to attract mosquitoes, and then uses green light to interfere with mosquito flight, thereby achieving mosquito repellency and improving mosquito repellency efficiency.

[0014] Compared with existing technologies, AC to DC conversion is achieved through a bridge rectifier DB1, and voltage regulation is achieved through a voltage regulator, thus ensuring a stable power supply for the main control module.

[0016] Compared with existing technologies, the photosensitive sensor, in conjunction with the lateral resistor and transistor Q2, enables automatic mosquito repellent activation when the optical fiber dims in the evening and automatic light ratio activation when the light brightens in the morning. This eliminates the need for manual operation, aligns with daily routines, and avoids energy waste or poor mosquito repellent efficiency caused by forgetting to turn it on.

[0017] In one possible implementation, the driving module further includes an LED lighting driver chip; several purple-green dual-color LED beads are connected in series at the DC positive output terminal of the bridge rectifier DB2 and electrically connected to the power input and constant current output ports of the LED lighting driver chip; the output current setting port of the LED lighting driver chip is connected to the DC negative output terminal of the bridge rectifier DB2 through a resistor RS1; the DC positive output terminal of the bridge rectifier DB2 is electrically connected to the DC negative output terminal of the bridge rectifier DB2 through an electrolytic capacitor EC3; and the DC positive output terminal of the bridge rectifier DB2 is electrically connected to the DC negative output terminal of the bridge rectifier DB2 through a resistor R11.

[0018] Compared with existing technologies, the drive module adds an LED lighting driver chip after passing through the bridge rectifier DB2, providing constant current output to power the purple-green dual-color LED beads for mosquito repellency.

[0023] Compared with existing technologies, different timers can be achieved by setting different timer buttons.

[0029] Figure 1 This is a circuit diagram of a photosensitive timed mosquito repellent controller according to the present invention. Detailed Implementation

[0030] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0031] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0032] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] See Figure 1 As shown in the figure, this application discloses a photosensitive timed mosquito repellent controller, comprising:

[0034] The power supply module includes a bridge rectifier DB1 and a voltage regulator. The AC input terminal of the bridge rectifier DB1 is electrically connected to the neutral and live wires, and the DC output terminal of the bridge rectifier DB1 is electrically connected to the input terminal of the voltage regulator.

[0035] The photosensitive module includes a photosensitive sensor and a transistor Q2. The input terminal of the voltage regulator is electrically connected to the base of the transistor Q2 through the photosensitive sensor, and the emitter of the transistor Q2 is grounded.

[0036] The drive module includes a bridge rectifier DB2, with several purple-green dual-color LED beads connected in series between the DC positive output terminal and the DC negative output terminal of the bridge rectifier DB2.

[0037] A button timer module, which includes multiple buttons for controlling different working durations, with one end of each button grounded.

[0038] The main control module's power supply terminal is electrically connected to the voltage regulator's output terminal. The collector of transistor Q2 and the voltage regulator's output terminal are both electrically connected to the main control module's photoelectric input port. The voltage regulator's input terminal is electrically connected to the main control module via the relay coil terminal. The first AC input terminal of bridge rectifier DB2 is electrically connected to the live wire via the relay contact terminal, and the second AC input terminal of bridge rectifier DB2 is electrically connected to the neutral wire. The other end of each button is electrically connected to the main control module. The main control module controls the relay's conduction duration based on the signals from the photoelectric input port and the button timing module.

[0039] In this embodiment, a photosensitive sensor is used to distinguish between day and night, and a button timer module is used to control the duration of nighttime activation, thus achieving autonomous timer control. The purple light from the purple-green dual-color LED beads is used to attract mosquitoes, and the green light is used to interfere with their flight, thereby repelling mosquitoes and improving mosquito repellency efficiency.

[0040] By employing a combination of purple and green dual-color LED beads and multi-wavelength LEDs, the system utilizes purple LEDs with wavelengths between 365nm and 395nm, leveraging mosquitoes' phototaxis to attract them. This is paired with green LEDs with wavelengths between 530nm and 590nm, which interfere with mosquitoes' flight and positioning due to their aversion to this wavelength. Through precise PCB circuit design, the current to each LED is controlled, ensuring stable illumination across different wavelengths. This achieves the dual effect of attracting and repelling mosquitoes, improving mosquito-repelling efficiency. This embodiment combines the characteristics of two light waves, covering a wider range of mosquitoes and proving effective against various types, resulting in higher mosquito-repelling efficiency than single-wavelength LEDs.

[0041] This embodiment uses purple-green dual-color LED beads to repel mosquitoes, which has the following advantages:

[0042] ①. Low radiation: The radiation produced by LED light sources is far lower than that of traditional mosquito repellent light sources such as ultraviolet lamps. It is harmless to human health and can be used safely in bedrooms, children's rooms and other places without causing harm to the eyes or skin.

[0043] ②. Pollution-free: It does not use chemical mosquito repellent ingredients, avoiding the smoke and harmful gases produced by the combustion or volatilization of mosquito coils and electric mosquito repellent liquids, reducing indoor air pollution and creating a green and healthy living environment for families.

[0044] ③. Energy saving and consumption reduction: LEDs have low power consumption, achieving efficient mosquito repellency while consuming little electricity. Combined with photosensitive and timer control, they only work when necessary, further reducing energy consumption and saving electricity costs in the long run.

[0045] ④. Long lifespan: LEDs have a long lifespan, reaching tens of thousands of hours. Compared with mosquito coils and electric mosquito repellent mats that need to be replaced frequently, this reduces usage costs and resource waste, reduces waste generation, and is in line with environmental protection principles.

[0046] In this embodiment, the main control module is based on a microcontroller, such as an Arduino Uno board. Users can set timing parameters via physical buttons, and the settings are stored in the EEPROM memory. The internal timer uses a precise clock source (such as a 16MHz crystal oscillator) as a reference to count the time. When the set start time (e.g., 7 PM) is reached, even if the light is not dim, the microcontroller will control the LED light source module to work if the timing function is activated; when the stop time (e.g., 6 AM) is reached, regardless of light or other conditions, it will stop working, achieving autonomous timing control.

[0047] In this embodiment, the HT48R063B microcontroller is selected. It boasts abundant resources, simple programming, and a built-in 16MHz clock source to provide a precise time reference for the timing function. Multiple digital and analog input / output pins facilitate connection to other modules, enabling integrated system control. Through precise time control achieved by the microcontroller, users can freely set mosquito repellent periods, accurately turning it on and off whether during nighttime sleep or specific activity times, meeting personalized needs and ensuring effective protection during peak mosquito activity periods.

[0048] In this embodiment, the first AC input terminal of the bridge rectifier DB1 is electrically connected to the live wire through a series resistor R2, a resistor R1 and a fuse, a capacitor C1 is connected in parallel across the resistor R2, and the second AC input terminal of the bridge rectifier DB1 is electrically connected to the neutral wire.

[0049] The first DC output terminal of the bridge rectifier DB1 is electrically connected to the input terminal of the voltage regulator. The second DC output terminal of the bridge rectifier DB1 is grounded. The input terminal of the voltage regulator is grounded through electrolytic capacitor EC1 and capacitor C2 respectively. The input terminal of the voltage regulator is electrically connected to the negative terminal of a Zener diode ZD1. The positive terminal of Zener diode ZD1 is grounded. The output terminal of the voltage regulator is grounded through electrolytic capacitor EC2 and capacitor C2 respectively.

[0050] AC to DC conversion is achieved through a bridge rectifier DB1, and voltage regulation is achieved through a voltage regulator, thus ensuring a stable power supply for the main control module.

[0051] In this embodiment, the photosensitive module further includes resistors R5, R6, R8, and R9, and capacitors C4 and C5. The first terminal of the photosensitive sensor is electrically connected to the input terminal of the voltage regulator. The second terminal of the photosensitive sensor is connected in series with resistors R8, R7, and R6 and electrically connected to the base of transistor Q2. The connection terminals of resistors R7 and R8 are electrically connected to the first terminal of resistor R9. The connection terminals of resistors R6 and R7 are electrically connected to the second terminal of resistor R9 through capacitor C5. The second terminal of resistor R9 is grounded. The collector of transistor Q2 is electrically connected to the output terminal of the voltage regulator through resistor R5. The collector of transistor Q2 is electrically connected to the emitter of transistor Q2 through capacitor C4.

[0052] The photosensitive sensor, in conjunction with the lateral resistor and transistor Q2, enables automatic sensing functionality. It automatically switches on and off based on ambient light, turning on mosquito repellent when the light dims in the evening and automatically adjusting the light ratio when the light brightens in the morning. This eliminates the need for manual operation, aligns with daily routines, and avoids energy waste or poor mosquito repellent efficiency caused by forgetting to turn it on.

[0053] The photosensitive sensor is a GM4537 photoresistor. Using a high-precision photoresistor as the core sensing element, it is extremely sensitive to changes in ambient light; its resistance value changes significantly under different light intensities. When the ambient light dims and reaches a set threshold (e.g., 50 lux, adjustable according to actual needs), the photoresistor's resistance increases. This change is converted into a voltage signal by a connected voltage conversion circuit and transmitted to the microcontroller, triggering the mosquito repellent function. When the light brightens beyond the threshold, the voltage signal changes, and the microcontroller receives this signal and deactivates the mosquito repellent function, thus automatically controlling mosquito repellency based on light levels.

[0054] In this embodiment, the driving module also includes an LED lighting driver chip; several purple-green dual-color LED beads are connected in series at the DC positive output terminal of the bridge rectifier DB2 and electrically connected to the power input and constant current output ports of the LED lighting driver chip; the output current setting port of the LED lighting driver chip is connected to the DC negative output terminal of the bridge rectifier DB2 through resistor RS1; the DC positive output terminal of the bridge rectifier DB2 is connected to the DC negative output terminal of the bridge rectifier DB2 through electrolytic capacitor EC3; and the DC positive output terminal of the bridge rectifier DB2 is connected to the DC negative output terminal of the bridge rectifier DB2 through resistor R11.

[0055] After passing through the bridge rectifier DB2, the drive module adds an LED lighting driver chip to provide constant current output, powering the purple-green dual-color LED beads for mosquito repellency. The LED light source has stable performance and can work continuously for a long time, ensuring uninterrupted mosquito repellency. By using a multi-wavelength combination of purple-green dual-color LED beads to repel mosquitoes, there are no problems such as the evaporation of effective ingredients or power depletion, providing users with long-lasting protection.

[0056] In this embodiment, the LED lighting driver chip is the SM2082EK chip.

[0057] Each button has a capacitor connected in parallel across its two ends. This capacitor is used to prevent accidental button presses that could cause timing inaccuracies.

[0058] Specifically, the buttons include a timer switch button, a 1-hour timer button, a 2-hour timer button, a 4-hour timer button, a 6-hour timer button, an 8-hour timer button, and an automatic button. Different timer settings can be achieved by using different timer buttons.

[0059] In this embodiment, a transistor Q1 is provided between the relay coil terminal and the main control module. The base of transistor Q1 is electrically connected to the main control module through resistor R3. The emitter of transistor Q1 is grounded. The collector of transistor Q1 is electrically connected to the first terminal of the relay coil. The second terminal of the relay coil is electrically connected to the input terminal of the voltage regulator. The first terminal of the relay coil is electrically connected to the positive terminal of diode D1. The negative terminal of diode D2 is electrically connected to the second terminal of the relay coil.

[0060] By controlling the on / off state of transistor Q1, the relay coil is powered on or off, which in turn controls the operation of the drive module, thus enabling the entire photosensitive timed mosquito repellent controller to start or stop.

[0061] In this embodiment, the main control module is grounded through a reset switch RST1, a capacitor C7 is connected in parallel across the two ends of the reset switch RST1, and the main control module is grounded through a series resistor R10 and a working indicator LED1.

[0062] By setting the reset switch RST1, all timing records are deleted and the system is reset. At the same time, the working indicator LED1 indicates whether the controller is working, making it easy for the user to observe.

[0063] Working principle:

[0064] During the day, the brightness is high, the resistance of the photoresistor is very small, the base of transistor Q2 is at a high level, transistor Q2 is turned on, the photoelectric input port of the main control module is at a low level, and the main control module does not work.

[0065] At night, when the brightness is low and the resistance of the photoresistor is high, the base of transistor Q2 is at a low level, causing Q2 to be cut off. The photoelectric input port of the main control module is at a high level, and the main control module operates. The signal input to the base of transistor Q1 through resistor R3 is high, turning Q1 on. This energizes the coil of relay K1, powering the driver module. The driver module then powers multiple purple-green dual-color LEDs via the bridge rectifier DB2 and the LED lighting driver chip, thus repelling mosquitoes. If the main control module receives a timing signal from the button timing module, it starts timing and stops after the preset time.
