Description

电热体调温保安插头
本实用新型涉及一种电路连接用插头,尤其是可对电热体进行调温的插头。
一般的电烙铁都没有调温装置,插上电源长时间待焊时会使烙铁头温度过高,造成烙铁头氧化;如果随时将插头拔出,再插上时需要几分钟的预热,很不方便。额外再装一调温装置往往既不实用又不经济,因此人们考虑利用电源插头进行调温,中国专利申请CN86202598U公开了一种"调温插头",是用现有二极插头改制而成,即在两插片间串有开关和二极管,当电烙铁需要保温时,拨动开关将二极管串入电路中,220伏交流电经整流后变为半波脉动电压,即可实现电烙铁低压保温。该插头为二极插头,而国家有关部门规定,电器应使用带接地线的三极插头。
本实用新型的目的是得到一种三极插头,可对电热体工作温度进行调节,并可显示插座的接地线是否正常。
本实用新型的目的是这样实现的:
一种电热体调温保安插头,由包括火线、零线和地线的三极插头组成,它包括:火线上串有二极管D,二极管D与开关K并联,开关K与双色发光二极管LED的总线相联,LED的分线分别与地线、火线相联。
双色发光二极管LED的分线分别与电阻R1、R2串联。
下面结合附图详述本实用新型。
附图为本实用新型电热体调温保安插头电路图。
参见附图,该插头的火线上串有并联的二极管D和开关K,开关K的一端与双色发光二极管LED的总线并联,LED的分线经电阻R`1、R2分别与地线、火线相联(即虚线框内部分),与地线相联的发光管为绿色,与火线相连的为红色。当该插头插入安装正确的插座时,当K处于接通状态时,电流从火线L→K→电热体RH→零线N构成回路,电源全压接通,电热体处于加热升温状态;同时电流从L→K→LED→R1→地线⊥,使绿色发光管G亮,表示接地线有效。当电热体需要保温时,将开关K断开,火线L输入交流电正弦波经二极管D整流后成为半波直流电,电流从火线L→R2→LED→RH→零线N构成回路,红色发光管R亮,这样,与绿色发光管一起使整个光指示灯总体呈橙红色。
当该插头插入安装不正规的插座时,如果没有接地线或火线、零线反接时绿色发光管均不会发亮,表明该插座安装不正确,当电热体需要低压保温时,将开关K断开仍能起到低压保温作用,红色发光管亮。
本实用新型不但能使电烙铁等电热体产生两种温度,达到调温、节能的目的,其接地指示还可保证电烙铁不带感应电,防止漏电事故的发生。同时,只要适当选择二极管D的容量,就可适用于电饭煲、阻性电烙铁、电熨斗、电烤箱等一系列电阻发热型电器的温度调节。
