Description

Technical Field

[0001] The utility model relates to the technical field of bird repellers, in particular to an ultrasonic bird repeller. Background Art

[0002] Ultrasonic bird repellers use physical bird repellers, using ultrasound to effectively drive birds away from production and living environments such as homes and workplaces. Bird repellers use an ultrasonic pulse to interfere with, stimulate and destroy the nervous system and physiological system of birds, causing physiological disorders to achieve the ultimate goal of driving away and killing birds. The ultrasonic waves used in ultrasonic bird repellers have the characteristics of being unable to penetrate obstacles, strong directionality, and fast attenuation. Therefore, a high-power bird repeller is used to propagate through countless reflections of ultrasonic waves to form an ultrasonic protection net covering the entire bird repeller space.

[0025] See also Figure 1 The present embodiment provides an ultrasonic bird repeller, comprising a main control circuit 1, an ultrasonic circuit 2, a power control circuit 3, a solar circuit 4 and a battery 5. The main control circuit 1 is connected to the ultrasonic circuit 2, the power control circuit 3 and the solar circuit 4 respectively, and the power control circuit 3 is also connected to the solar circuit 4 and the battery 5.

[0026] See also Figure 2 The power control circuit 3 includes a charging chip U3, a resistor R12, a capacitor C7, a capacitor C8, a charging interface J1, a green LED light L1, a red LED light L2, a resistor R16 and a resistor R18. The second pin of the charging chip U3 is connected to one end of the resistor R12, and the other end of the resistor R12 is respectively connected to the first pin of the charging chip U3, the third pin of the charging chip U3 and the ground end. The fourth pin of the charging chip U3 is respectively connected to the charging interface J1, one end of the capacitor C7 and the working voltage USB_5V. The fifth pin of the charging chip U3 is respectively connected to the battery 5, the solar circuit 4 and the main control circuit 1. The sixth pin of the charging chip U3 is connected to one end of the resistor R16 after passing through the green LED light L1. The seventh pin of the charging chip U3 is connected to one end of the resistor R18 after passing through the red LED light L2. The eighth pin of the charging chip U3 is respectively connected to the other end of the resistor R16, the other end of the resistor R18 and the working voltage USB_5V. The resistance values ​​of the resistors R12, R16 and R18 are all 1000 ohms. The power control circuit 3 realizes trickle current, constant current and constant voltage charging of the battery 5 through the charging chip U3.

[0027] The following is the main working principle of the power control circuit 3:

[0028] 1) Temperature detection and adaptive adjustment:

[0029] The first pin of the charging chip U3 is grounded, and is used to detect the charging temperature of the battery 5 and adaptively adjust the charging current according to the temperature to ensure that the battery 5 is charged under safe and efficient conditions.

[0030] 2) Charging current setting and monitoring:

[0031] The second pin of the charging chip U3 is connected to a 1000 ohm resistor R18 to set and monitor the charging constant current.

[0032] 3) Power supply stabilization and filtering

[0033] The fourth pin of the charging chip U3 is connected to the charging interface J1 and is filtered through the parallel capacitor C7 to ensure voltage stability.

[0034] 4) Charging status indication:

[0035] The seventh pin of the charging chip U3 is connected to the red LED light L2 and the resistor R18 to indicate the charging status. When charging is in progress, the seventh pin of the charging chip U3 outputs a low level and lights up the red LED light L2; the sixth pin of the charging chip U3 is connected to the green LED light L1 and the resistor R16 to indicate that charging is complete. At the end of charging, the sixth pin of the charging chip U3 outputs a low potential and lights up the green LED light L1, indicating that charging is complete.

[0036] 5) Charging mode switching:

[0037] When the voltage of battery 5 is lower than 3V, the trickle mode is used for pre-charging; when the voltage of battery 5 exceeds 3V, it enters the constant current mode, and the charging current is controlled by the second pin of the charging chip U3 and the resistor R12; when the voltage of battery 5 is close to 4.2V, the charging current gradually decreases and enters the constant voltage charging mode; when the voltage of battery 5 reaches 4.2V, the charging ends and the charging current drops to 0. The three charging modes of trickle, constant current and constant voltage can more comprehensively cover the entire charging process of battery 5 from low power to full power, ensuring that battery 5 obtains the best charging effect.

[0038] The power control circuit 3 can more effectively manage the charging process of the battery 5 through temperature detection and adaptive adjustment, charging current setting and monitoring, and charging mode switching, thereby extending the service life of the battery 5; at the same time, it avoids the overcharging or over-discharging problems that may occur in a single constant current or constant voltage charging mode, and reduces the safety risks of thermal runaway and fire of the battery 5; in addition, through the red LED light L2 and the green LED light L1, the user can intuitively understand the charging status of the battery 5, so as to take corresponding measures in time.

[0039] In one embodiment, the charging interface J1 is a Type-C interface. The use of the Type-C interface can ensure the compatibility of the ultrasonic bird repeller with other charging devices, which is convenient for users to use. At the same time, the Type-C interface supports high-power charging, which can provide a faster charging speed for the ultrasonic bird repeller, so that the battery 5 can be quickly filled and the waiting time can be reduced.

[0040] In one embodiment, the model of the charging chip U3 is JL4056. The charging chip U3 of this model adopts an internal PMOSFET architecture and has a reverse charging protection circuit without the need for an external isolation diode.

[0041] See also Figure 3 In one embodiment, the main control circuit 1 includes a main control chip U5, a resistor R19, a capacitor C11, a switch button K1, a working indicator light L3 and a resistor R20. The first pin of the main control chip U5 is connected to the power control circuit 3 and one end of the capacitor C11 respectively after passing through the resistor R19. The eighth pin of the main control chip U5 is connected to the other end of the capacitor C11 and the ground terminal respectively. The sixth pin of the main control chip U5 is connected to the ultrasonic circuit 2. The fifth pin of the main control chip U5 is connected to the ground terminal after passing through the switch button K1. The seventh pin of the main control chip U5 is connected to the ground terminal after passing through the resistor R20 and the working indicator light L3 in sequence. The main control chip U5 controls the operation of the ultrasonic circuit 2 through the key state of the switch button K1.

[0042] The following is the detailed working principle of the main control circuit 1:

[0043] 1) Power supply and filtering:

[0044] The first pin VDD of the main control chip U5 is the positive power supply, and the eighth pin GND is the negative power supply, and the two form a power supply loop; the capacitor C11 is connected to the power supply loop to filter out noise in the power supply and ensure that the main control chip U5 obtains a stable voltage.

[0045] 2)Key monitoring:

[0046] The fifth pin of the main control chip U5 is a key input pin with a pull-up resistor inside; when the switch button K is not pressed, the fifth pin of the main control chip U5 maintains a high level state through the pull-up resistor. When the switch button K is pressed, the two ends of the switch button K are connected, and the fifth pin of the main control chip U5 is directly connected to GND, thus changing to a low level state.

[0047] 3) Working status judgment and response:

[0048] The U5 chip monitors the status of the PB1 pin in real time; when the fifth pin of the main control chip U5 changes from a high level to a low level, the main control chip U5 starts to judge the current working status;

[0049] If the ultrasonic circuit 2 and the working indicator light L3 are currently in the off state, the main control chip U5 recognizes the low level of the fifth pin as a start signal; at this time, the seventh pin of the main control chip U5 outputs a high level, lighting up the working indicator light L3, and the sixth pin of the main control chip U5 outputs a pulse waveform, first outputting a 1-second sound waveform audible to the human ear, and then outputting a 10-second ultrasonic waveform, which is played through the ultrasonic speaker of the ultrasonic circuit 2 to achieve the bird repelling function;

[0050] If the ultrasonic circuit 2 and the working indicator light L3 are currently in working state, the main control chip U5 recognizes the low level of the fifth pin as a shutdown signal; at this time, the seventh pin of the main control chip U5 outputs a low level, turns off the working indicator light L3, the sixth pin of the main control chip U5 stops outputting the waveform, and the ultrasonic speaker of the ultrasonic circuit 2 stops making sound.

[0051] See also Figure 3 In one embodiment, the ultrasonic circuit 2 includes a bird repellent horn J2, and two ends of the bird repellent horn J2 are respectively connected to the sixth pin of the main control chip U5 and the fifth pin of the charging chip U3. By directly connecting the bird repellent horn J2 to the main control chip U5 and the charging chip U3, additional circuit elements and connection lines are reduced, making the design of the entire ultrasonic circuit 2 more compact and integrated.

[0052] See also Figure 4 In one embodiment, the solar circuit 4 includes a solar panel J3 and a diode D1. One end of the solar panel J3 is connected to the fifth pin of the charging chip U3 through the diode D1, and one end of the solar panel J3 is connected to the ground terminal. The solar panel J3 is responsible for capturing solar energy and converting it into electrical energy, so as to realize charging using solar energy when there is sufficient sunlight, which is both energy-saving and environmentally friendly. The diode D1 plays a role in preventing reverse current in the circuit, that is, when the solar panel J3 does not generate electrical energy in the absence of sunlight, it can prevent the battery 5 from discharging through the solar panel J3, ensuring the stability and safety of the circuit.

[0053] In one embodiment, the capacity of the battery 5 is 2200 ma.

[0054] It should be noted that the ultrasonic bird repeller provided by the utility model is a technological product designed specifically for protecting vehicles. It uses ultrasonic technology to effectively drive birds away from vehicles without harming the birds.

As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
