Description

Technical Field

[0001] This utility model relates to a mosquito-killing device, and more particularly to a mosquito-killing lamp. Background Technology

[0002] Most outdoor mosquito killer lamps on the market require manual cleaning of the electric shock net after the lamp is turned off and the mosquitoes are killed. This necessitates regular cleaning of the lamp. If it is not cleaned in time, the electric shock net will be blocked by dead mosquitoes, reducing the mosquito-killing effect of the lamp.

[0003] In the prior art, patent document CN218898032U discloses a mosquito-killing lamp. Its technical solution involves a cleaning device on the outer surface of an electric grid. This device includes two cylindrical rods, with a cylindrical tube slidably connected to the outer surface of each rod. A rectangular rod is fixedly connected to the outer surface of the cylindrical tube, and a brush is mounted on the outer surface of the rectangular rod. Pulling the cylindrical tube causes it to slide on the outer surface of the cylindrical rod, moving the rectangular rod and using the brush on its outer surface to clean both sides of the electric grid, scraping off any dead mosquitoes stuck in it. However, this cleaning method requires manual pulling, making it cumbersome and inconvenient to use. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0023] Reference Figures 1 to 5An ultra-high frequency vibration automatic cleaning mosquito killer lamp includes a housing 1. An electric shock net 2, a mosquito-attracting lamp tube 3, and a power supply mainboard 4 are installed inside the housing 1. The power supply mainboard 4 is electrically connected to the electric shock net 2 and the mosquito-attracting lamp tube 3. A vibration motor 5 is installed at one end of the electric shock net 2. A control circuit board 6 for controlling the vibration motor 5 is provided inside the housing 1, and the control circuit board 6 is electrically connected to the power supply mainboard 4. This invention uses a vibration motor 5 at one end of the electric shock net 2. The high-frequency vibration of the motor 5 shakes off mosquitoes accumulated on the electric shock net 2, effectively preventing mosquitoes from accumulating on the net and affecting the mosquito-killing efficiency of the lamp. Furthermore, the vibration motor is controlled by the control circuit board, which allows for timed start and stop of the motor, achieving automated cleaning and facilitating user cleaning.

[0024] As a further improvement of this utility model, the electric shock net 2 includes a frame 21, and electric poles 22 are arranged along the length direction inside the frame 21. The electric poles 22 are electrically connected to the power main board 4. The vibration motor 5 is installed on the inner side wall of the frame 21. Specifically, the vibration motor 5 is fixedly connected to the frame 21 by screws. In this embodiment, the vibration motor 5 can be an R2838 type vibrator.

[0025] As a further improvement of this utility model, the control circuit board 6 includes a power input section, a voltage regulator section, and a control section. The input terminal of the power input section is electrically connected to the power output terminal of the power main board 4, the output terminal of the power input section is connected to the input terminal of the voltage regulator section, the output terminal of the voltage regulator section is connected to the input terminal of the control section, and the output terminal of the control section is electrically connected to the vibration motor 5. In this embodiment, the power main board 4 is a common circuit board used to control the operation of mosquito killer lamps, used to supply power to the electric shock net 2 and the mosquito-attracting lamp tube 3 or control the switch. In this embodiment, the control circuit board 6 and the vibration motor 5 can be directly installed on a traditional mosquito killer lamp. It is only necessary to connect the power input section of the control circuit board 6 to the live wire ACL and neutral wire ACN of the power main board 4 to provide input voltage to the control circuit board 6. This enables a rapid upgrade of the cleaning function of the traditional mosquito killer lamp, improving the cleaning efficiency of the mosquito killer lamp without replacing the main body of the device.

[0026] As a further improvement of this utility model, the power input section includes a rectifier bridge BD1, a control chip IC1, and a transformer T1. Pin 1 of the rectifier bridge BD1 is connected to the live wire ACL via a fuse F1, and pin 3 of the rectifier bridge BD1 is connected to the neutral wire ACN.

Pin 2 of the rectifier bridge BD1 is divided into two paths: one path is connected in series with pin 1 of the transformer T1 via a capacitor C5 and a switching diode D1, and the other path is connected to pin 3 of the transformer T1. Resistors R2 and R1 are connected in parallel with capacitor C5. Pin 4 of the rectifier bridge BD1 is grounded. An electrolytic capacitor EC1 is connected between pins 2 and 4 of the rectifier bridge BD1; pins 5-8 of the control chip IC1 are simultaneously connected to pin 1 of the transformer T1; pins 1 and 2 of the control chip IC1 are simultaneously grounded; a capacitor C4 is connected between pins 3 and 2 of the control chip IC1; pin 4 of the control chip IC1 is connected to pin 4 of the transformer T1 through a switching diode D3; a resistor R3 and a Zener diode DZ1 are connected in series between pins 3 and 4 of the control chip IC1; and an electrolytic capacitor EC2 is connected between pins 2 and 4 of the control chip IC1. In this embodiment, the power input terminal of the rectifier bridge BD1 is connected to the live wire ACL and neutral wire ACN of the power supply motherboard 4, which can convert AC power to DC power. Then, the control chip IC1 outputs a PWM signal to drive an external power MOSFET, causing it to alternately turn on / off at high frequency. The voltage is then transformed through a transformer to provide a stable 12V DC power supply to the voltage regulation and control sections.

[0027] Specifically, the control chip IC1 can be an FSD8022, a high-performance offline PWM switching power supply controller that meets green environmental protection standards. The circuit features a built-in high-voltage start-up circuit, a soft-start circuit, and multiple protection functions, simplifying the power supply peripherals for small household appliances and chargers while offering extremely high reliability. Under certain conditions, this circuit can also be used as a non-isolated application. The pin functions of the control chip IC1 are as follows: pins 1 and 2 are grounded; pin 3 is the feedback input; pin 4 is the power supply; and pins 5-8 are output pins connected to the switching transformer.

[0028] As a further improvement of this utility model, the voltage regulation section includes a linear voltage regulator U2. The input terminal of the linear voltage regulator U2 is connected to the output terminal of the transformer T1. The 8th pin of the transformer T1 has two outputs: one connected to the 1st pin of the linear voltage regulator U2, and the other connected to the 1st pin of the motor power supply interface M1. The 10th pin of the transformer T1 is grounded. An electrolytic capacitor EC3 is connected between the 8th and 10th pins of the transformer T1. A resistor R4 and a capacitor C1 are connected in parallel with the electrolytic capacitor EC3. In this embodiment, the linear voltage regulator U2 steps down the 12V voltage to 5V to provide a stable voltage for the main control chip U1.

[0029] As a further improvement of this utility model, the control part includes a main control chip U1. The first pin of the main control chip U1 is connected to the third pin of the linear regulator U2. The second pin of the linear regulator U2 is grounded. An electrolytic capacitor EC4 is connected between the second and third pins of the linear regulator U2. The third pin of the linear regulator U2 is split into two outputs through capacitor C2. One output is connected in parallel with the electrolytic capacitor EC4, and the other output is connected to the first pin of power transistor Q1. The power transistor Q1 is used to amplify the output current of the main control chip U1 to drive the motor. The second pin of the power transistor Q1 is connected to the second pin of the motor power supply interface M1. The motor power supply interface M1 is connected to the vibration motor 5. The third pin of the power transistor Q1 is connected to the seventh pin of the main control chip U1 through resistor R4. In this embodiment, the main control chip U1 is model NE555, a classic timer / oscillator chip. The functions of its pins are as follows: pin 1 is power supply, pin 2 is trigger point, pin 3 is output, pin 4 is reset, pin 5 is control, pin 6 is reset lock, pin 7 is discharge, and pin 8 is ground. The vibration motor 5 can be timed using the timing function of the main control chip U1. Specifically, when the mosquito killer lamp is powered on and automatically cleans, the vibration motor 5 vibrates for 2 seconds, then stops for 2 seconds, then starts again for 2 seconds, then stops for 2 seconds, and then starts again for 3 seconds. During the first 2 seconds, the vibration motor 5 operates at 2000 RPM; during the second 2 seconds, it operates at 3000 RPM; and during the final 3 seconds, it operates at 4500 RPM. The speed increases gradually from low to high, and the noise also increases gradually rather than bursting out suddenly, avoiding any startling effect from sudden high-frequency vibration noise.

[0030] Working principle: The power input terminal of the control circuit board 6 is connected to the AC power supply of the main power board 4. The rectifier BD1 converts the AC power to DC power, and then the control chip IC1 steps down the DC power to 12V. The DC power is then output to the linear regulator U2 and the motor power supply interface M1 through the transformer T1. The linear regulator U2 steps down the 12V voltage to the working voltage of the main control chip U1, which is 5V. The control port of the motor power supply interface M1 is connected to the power transistor Q1 to amplify the output current of the main control chip U1 to drive the vibration motor.
