PTC Heating Element Solution for Electric Mosquito Liquid Heater
PTC heating element has the advantages of constant temperature precision, safety and energy saving, and long life in electric mosquito liquid heaters, which can significantly improve product performance. Through customized design, it can adapt to different electric mosquito liquid volatilization requirements, providing users with more efficient and safer mosquito repellent solutions.
1. Application background
The electric mosquito liquid heater is a common household mosquito repellent device. It heats the electric mosquito liquid to volatilize the effective ingredients (such as pyrethroids) to achieve the mosquito repellent effect. Traditional electric mosquito liquid heaters usually use resistance wire heating, but there are problems such as unstable temperature, high energy consumption, and safety hazards. PTC (positive temperature coefficient) heating element has become an ideal choice for electric mosquito liquid heaters due to its automatic constant temperature, energy-saving and efficient, safe and reliable characteristics.
2. Advantages of PTC heating element
Automatic constant temperature: After the PTC heating element reaches the set temperature, the resistance increases sharply and the power automatically decreases to avoid overheating and maintain a stable volatilization effect. Energy saving and high efficiency: Compared with traditional resistance wires, PTC heating elements only heat at high power in the initial stage, and then maintain low power consumption operation to save electricity. Safe and reliable: no open flame, no risk of overheating, even if used for a long time, the electric mosquito liquid bottle will not be burned or cause a fire. Long life: PTC materials are resistant to high temperatures and oxidation, and their service life is far longer than that of ordinary resistance wires.
3. Customized solution design
