分清类型是首要市场上出售的电热毯一般可分为三类:1、普通型电热毯采用220V供电,靠开关的作用实现电热毯通电发热与断电降温。其结构简单,但控温不方便。2、调温型电热毯采用调温开关达到控温目的。市场上有由PTC元件构成温控器的调温电热毯。其结构更简单,成本低,但性能不稳定。3、安全型电热毯。指使用29V以下工作电压的电热毯,利用变压器将220V的交流电转换成安全电 Types of distinction is the primary market for the sale of electric blanket generally can be divided into three categories: 1, ordinary type electric blanket 220V power supply, by the role of the switch to achieve electric blanket heating and cooling power off. Its structure is simple, but the temperature is not convenient. 2, thermostat type electric blanket temperature control switch to achieve the purpose of temperature. Market by the PTC components temperature thermostat electric blanket. Its structure is simple, low cost, but the performance is not stable. 3, safe electric blanket. Refers to the use of the working voltage of 29V following the blanket, the use of transformers to 220V AC power into safety
