口腔矫形科常用酒精灯烤热蜡刀,烤软蜡片,用酒精喷灯吹光粗制义齿蜡型等,工作效率低,使用不方便。我们试制的齿科矫形电热综合机,具有电蜡勺、电吹风、电温蜡三种功能,经北京医学院附属口腔医院等单位长期使用,效果良好。它的电路原理见图1所示。电蜡勺仿内热式电烙铁,长18cm,粗约1cm,功耗约3～6W,工作电压不超过6伏。
Oral orthopedics commonly used alcohol lamp grilled hot wax knife, roasted soft wax tablets, with alcohol torch light crude denture wax, etc., low efficiency, inconvenient to use. Our trial of dental orthopedic integrated machine, with electric wax spoon, hair dryer, electric Wax three functions, the Beijing Medical College Affiliated Stomatological Hospital and other units long-term use, the effect is good. Its circuit diagram shown in Figure 1. Electric wax spoon imitation thermal electric iron, length 18cm, rough about 1cm, power consumption of about 3 ~ 6W, the working voltage does not exceed 6 volts.
