The new mosquito and insect repellent products are now on the market. The modeling design that removes the sense of distance from the industrial machine is integrated into the piano key opening design, and the light is rear-mounted to reduce the direct irradiation of the light emitted by the product to people. The product uses ultrasonic waves to repel indoor reptiles, and uses the phototaxis of flying insects to lure insects with purple light and then eliminate them.
