Problems solved by technology

[0002] Nowadays, most of the household appliances that can play the heating function are installed heating tubes on the inside of the appliances. When the heating tubes work, heat is generated to heat the food. The traditional heating tubes are made of metal, and the existing heating tube processing technology The heat pipe of the traditional technology is easy to rust and has a short service life, which is the main shortcoming of the traditional technology
