[0015] 1. By setting up a fan, a guide hood, a closing plate, a resistance-increasing groove, and a return spring, the fan blows airflow through the air outlet to the guide hood. The closing plate moves downward after being impacted by the airflow. The concave surface of the resistance-increasing groove optimizes the closing plate's ability to impede the airflow, ensuring that the closing plate moves smoothly downward. The airflow enters the bottom space of the insect trap through the gap between the closing plate and the guide hood. Flying insects near the insect-attracting lamp are captured by the airflow due to the pressure and enter the insect trap. Since the airflow is continuously blown out, the flying insects cannot escape from the insect trap through the gap between the closing plate and the guide hood. When the closing plate moves downward, the four lifting rods move downward synchronously through the bottom plate. The return spring is stretched by the middle plate and the bottom plate. When the fan is powered off and stops blowing airflow, the return spring drives the bottom plate, lifting rods, and closing plate to return to their original positions, re-closing the bottom of the guide hood and preventing the flying insects from escaping.

[0016] 2. By setting up photovoltaic panels, hanging brackets, controllers, and air inlets, the photovoltaic panels are fixed to the top of the device via mounting plates. On sunny days, they convert solar energy into electrical energy to power the device, achieving energy saving and improving the device's applicability. The controller is fixed inside the insect-attracting box via hanging brackets to control the insect-attracting lamps and fans. Furthermore, through an integrated DC-AC converter, the DC power provided by the photovoltaic panels is converted into AC power. Outside air enters the insect-attracting box through two air inlets, providing airflow for the fans. The air inlets are located at the bottom on both sides of the controller and are designed with a lower outer and higher inner structure to effectively prevent rainwater backflow and avoid short circuits in the internal components of the controller during rainy days.

[0017] 3. By setting a limiting frame, positioning pin, finger grooves, and pull plate, the flow guide is secured to the top of the insect trap by the limiting frame, and positioned by the interlocking of the positioning pin and the pin hole. Therefore, the flow guide can be freely lifted from the top of the insect trap, which is convenient for maintaining and cleaning the internal parts of the insect trap. The process of reinstalling the flow guide back to the top of the insect trap is also simple. By pinching one end of the pull plate with the two finger grooves, the pull plate can be pulled out of the insect trap, which is convenient for cleaning the flying insects inside the insect trap from below.
