Description

Technical Field

[0001] This utility model relates to the field of mosquito repellent electrical technology, and in particular to a solar-powered mosquito repellent device. Background Technology

[0002] There are many types of mosquito killers available, including light-based mosquito killers and chemical-based mosquito killers. Light-based mosquito killers utilize mosquitoes' phototaxis, attracting them with light emitted from the device and using a high-voltage electric grid around the light source to kill them. However, their effectiveness is relatively poor, and they consume a lot of electricity, pose significant risks, and are unsafe. Chemical-based mosquito killers primarily use the odor of chemical agents to repel or poison mosquitoes. They are more effective in small, poorly ventilated spaces, but they are harmful to humans and often lead to mosquito resistance, reducing their effectiveness. Furthermore, their effectiveness is less pronounced in well-ventilated, open spaces. Utility Model Content

[0025] The technical solutions of the embodiments of this application are briefly described below:

[0026] According to some embodiments, such as Figures 1 to 3 As shown, this application provides a solar-powered mosquito repellent device, the mosquito repellent device comprising:

[0027] Photovoltaic power generation system;

[0028] The charging control circuit includes a relay K, and the first terminal of the contactor of the relay K is connected to the output terminal of the photovoltaic power generation system.

[0029] The charging circuit and battery BT are connected together. The second terminal of the contactor of relay K is connected to the input terminal of the charging circuit, and the output terminal of the charging circuit is connected to the battery BT.

[0030] The main control chip and the power detection circuit are connected to the battery BT, the control terminal of the charging control circuit and the output terminal of the power detection circuit respectively, and the input terminal of the power detection circuit is connected to the battery BT.

[0031] The ultrasonic drive circuit and the ultrasonic mosquito repellent LS are connected. The drive pin 102 of the main control chip is connected to control the ultrasonic drive circuit, and the ultrasonic drive circuit is connected to control the ultrasonic mosquito repellent LS.

[0032] The working principle of the above embodiment is as follows: when the battery BT's charge level is lower than a first preset threshold, the main control chip controls the contactor of relay K to close through the charging control circuit, and the photovoltaic power generation system charges the battery BT through the charging circuit. The charging circuit is used for rectification and filtering, and the charge detection circuit is used to detect the voltage of the battery BT so that the main control chip can determine the battery BT's charge level based on the voltage. The main control chip controls the ultrasonic mosquito repellent LS to operate through the ultrasonic drive circuit.

[0033] This application utilizes an ultrasonic mosquito repellent LS to overcome the shortcomings of photoelectric mosquito control, such as poor effectiveness, high power consumption, significant risks, and safety concerns, as well as the harmful effects of chemical mosquito control on humans and the development of resistance in mosquitoes. This application uses a photovoltaic power generation system to power the ultrasonic mosquito repellent LS, reducing carbon emissions, reducing mains power consumption, and making it more environmentally friendly. This application also includes a power detection circuit. When the battery BT's power level falls below a first preset threshold, the main control chip controls the contactor of relay K to close via the charging control circuit, charging the battery BT, making the mosquito repellent device of this application more intelligent.

[0034] The following is in conjunction with the appendix to this instruction manual. Figures 1 to 4 The preferred embodiments of this disclosure will be further described in detail below.

[0035] According to some embodiments, such as Figure 1 As shown, the photovoltaic power generation system includes a photovoltaic power generation module, an energy storage module, an inverter, and a transformer. The output terminal of the photovoltaic power generation module is connected to the input terminal of the energy storage module and the inverter. The output terminal of the inverter is connected to the primary coil of the transformer. The secondary coil of the transformer is connected to the first terminal of the contactor of relay K.

[0036] The working principle of the above embodiment is as follows: when the battery BT's charge level is higher than a first preset threshold, the main control chip controls the contactor of relay K to open through the charging control circuit. At this time, the photovoltaic power generation module charges the energy storage module, storing the excess electricity generated by the photovoltaic in the energy storage module so that it can charge the battery BT when there is no sunlight and the battery BT is out of power.

[0037] According to some embodiments, such as Figure 1 As shown, the photovoltaic power generation system also includes a circuit breaker S1. The first end of the circuit breaker S1 is connected to the output end of the photovoltaic power generation module, and the second end of the circuit breaker S1 is connected to the input end of the energy storage module and the inverter.

[0038] According to some embodiments, such as Figure 2 As shown, the charging control circuit also includes a first NPN transistor QN1, a diode D, a first resistor R1, and a second resistor R2, with the specific connection structure as follows.

[0039] The base of the first NPN transistor QN1 is connected to the control output pin 202 of the main control chip through the first resistor R1. The collector of the first NPN transistor QN1 is connected to one end of the coil of the relay K and the positive terminal of the diode D. The other end of the coil of the relay K is connected to the negative terminal of the diode D and connected to the power supply through the second resistor R2.

[0040] When the photovoltaic power generation system needs to charge the battery BT, the control output pin 202 of the main control chip outputs a high-level signal, the first NPN transistor QN1 is turned on, the contactor of the relay K is energized, and the battery BT begins to charge.

[0041] When the photovoltaic power generation system does not need to charge the battery BT, the control output pin 202 of the main control chip outputs a low-level signal, the first NPN transistor QN1 is turned off, the contactor of relay K is disconnected, and the battery BT stops charging.

[0042] According to some embodiments, the charging circuit is used for rectification and filtering, such as... Figure 3 As shown, the charging circuit includes a fuse F, a rectifier bridge DB, a third resistor R3, a first capacitor C1, and a second capacitor C2. Its specific connection structure is as follows:

[0043] One end of fuse F and the first input terminal of rectifier bridge DB are connected to the second terminal of contactor of relay K. The other end of fuse F is connected to the second input terminal of rectifier bridge DB. The positive output terminal of rectifier bridge DB is connected to one end of first capacitor C1, one end of second capacitor C2 and the positive terminal of battery BT through third resistor R3. The negative output terminal of rectifier bridge DB is grounded. The other ends of first capacitor C1, the other ends of second capacitor C2 and the negative terminal of battery BT are grounded.

[0044] Furthermore, such as Figure 3 As shown, the charging circuit also includes a resistor-capacitor (RC) step-down circuit. The RC step-down circuit is used to reduce the voltage. The RC step-down circuit is located between the other end of the fuse F and the second input terminal of the rectifier bridge DB. The RC step-down circuit includes a fourth resistor R4 and a third capacitor C3. One end of the fourth resistor R4 and one end of the third capacitor C3 are connected to the other end of the fuse F. The other end of the fourth resistor R4 and the other end of the third capacitor C3 are connected to the second input terminal of the rectifier bridge DB.

[0045] According to some embodiments, such as Figure 3 As shown, the power detection circuit includes a fifth resistor R5, a sixth resistor R6, and a fourth capacitor C4. One end of the fifth resistor R5 is connected to the positive terminal of the battery BT, and the other end of the fifth resistor R5 is connected to one end of the sixth resistor R6, one end of the fourth capacitor C4, and the detection input pin 201 of the main control chip. The other ends of the sixth resistor R6 and the other ends of the fourth capacitor C4 are grounded.

[0046] Among them, the fifth resistor R5 and the sixth resistor R6 are used for voltage division, and the fourth capacitor C4 is used for filtering.

[0047] According to some embodiments, such as Figure 4 As shown, the ultrasonic driving circuit includes a second NPN transistor QN2, a PNP transistor QP, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, and an eleventh resistor R11. Its specific connection structure is as follows.

[0048] The first electrode of the ultrasonic mosquito repellent LS is connected to the emitter of the second NPN transistor QN2 and the emitter of the PNP transistor QP. The collector of the second NPN transistor QN2 is connected to the power supply through the eighth resistor R8. The collector of the PNP transistor QP is grounded through the ninth resistor R9. The bases of the second NPN transistor QN2 and the PNP transistor QP are connected to the drive pin 102 of the main control chip through the seventh resistor R7. The second electrode of the ultrasonic mosquito repellent LS is connected to one end of the tenth resistor R10 and one end of the eleventh resistor R11. The other end of the tenth resistor R10 is connected to the power supply, and the other end of the eleventh resistor R11 is grounded.

[0049] Furthermore, such as Figure 3 As shown, the mosquito repellent device also includes a switching circuit, which comprises a manual switch S2, a twelfth resistor R12, and a thirteenth resistor R13. Its specific connection structure is as follows:

[0050] One end of the manual switch S2 is connected to the other end of the fifth resistor R5 and one end of the sixth resistor R6. The other end of the manual switch S2 is connected to one end of the thirteenth resistor R13 and the switch signal receiving pin 101 of the main control chip through the twelfth resistor R12. The other end of the thirteenth resistor R13 is grounded.

[0051] The working principle of the above embodiment is as follows: When the mosquito repellent device needs to be activated, the manual switch S2 is closed. The main control chip's switch signal receiving pin 101 receives a high-level signal through the manual switch S2. The main control chip then outputs a PWM modulation flat signal to the base of the second NPN transistor QN1 and the base of the PNP transistor QP through the drive pin 102. When the PWM modulation flat signal is high, the ultrasonic mosquito repellent LS is forward-biased; when the PWM modulation flat signal is low, the ultrasonic mosquito repellent LS is reverse-biased. This allows the ultrasonic mosquito repellent LS to receive AC power, and the ultrasonic mosquito repellent LS then operates.

[0052] When the mosquito repellent device needs to be turned off, the manual switch S2 is turned off. The switch signal receiving pin 101 of the main control chip receives a low-level signal through the thirteenth resistor R13. The drive pin 102 of the main control chip does not output a signal, and the ultrasonic mosquito repellent LS stops working.

[0053] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0054] Although this disclosure has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Because this disclosure can be embodied in many forms without departing from the spirit or substance of this application, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims.
