It seems like you're describing a multifunctional electronic insect repellent device that offers various features for pest control. Here's a concise summary of the key points you've mentioned: Product Features: Portability: Small in size, making it easy to carry and use both outdoors and indoors. USB Power Supply: Equipped with a USB interface that allows for plug-and-play operation with a power adapter, computer, or mobile power supply. It can also be used in a car, ensuring a safe and fast charging method. Multifunctionality: Ultrasonic Technology: Simultaneously produces ultrasonic waves to deter pests. Infrared Rays: Utilizes infrared technology, similar to sound waves, for pest control. Constant Temperature Heating: Features a PTCR element for maintaining a constant temperature, enhancing the repelling effect. Unique Advantage: Unlike similar products that only use ultrasonic waves, this device is a comprehensive electronic insect repellent that incorporates multiple technologies. Automatic Frequency Conversion: The device produces three kinds of sound waves with constantly changing frequencies to prevent pests like mosquitoes from developing "adaptability" or "immunity" to a fixed frequency. Functions: Natural Enemy Mimicry: Designed to repel biting female mosquitoes by imitating the sound of their natural enemies, such as dragonflies or male mosquitoes. Constant Temperature Heating: Uses a PTCR element to maintain a constant temperature for effective mosquito repelling. Ultrasonic Waves: Utilizes 9-36KHZ resonance technology and modern microelectronic means to produce extremely low-frequency ultrasonic waves and infrared rays intermittently, creating a pulse sound wave characteristic of mosquitoes. Impact on Pests: Affects the auditory and nervous systems of pests like mice, mosquitoes, and bugs. Particularly sensitive pests become agitated and distressed, leading them to flee or become inactive, lose their appetite, and cease reproduction and invasion. This product aims to drive away mosquitoes and mice effectively, providing a comprehensive solution for pest control.
