As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5; the upper ejector pin 121 of described overheat protector push rod 12 is made for ceramic material; the lower push rod 122 of described overheat protector push rod 12 is made for meltability engineering plastics; the upper ejector pin 121 that ceramic material is made makes upper ejector pin 121 insulating properties better; it is more timely that the lower push rod 122 that meltability engineering plastics are made makes lower push rod 122 melt; guarantee that overheat protector push rod 12 declines in time, accurate disconnecting circuit.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5; upper ejector pin 121 can also do following accommodation with the manufactured materials of lower push rod 122; the upper ejector pin 121 of described overheat protector push rod 12 is made for ceramic material; the lower push rod 122 of described overheat protector push rod 12 is made for meltability metal material; can guarantee that overheat protector push rod 12 declines in time equally, accurate disconnecting circuit.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, upper ejector pin 121 can also do following accommodation with the manufactured materials of lower push rod 122, the upper ejector pin 121 of described overheat protector push rod 12 is made for meltability engineering plastics, the lower push rod 122 of described overheat protector push rod 12 is made for meltability metal material, therefore upper ejector pin 121 and lower push rod 122 all can melt, when bimetal leaf temperature control lost efficacy, after continuation heats up and reaches the fusing point of lower push rod by the heatable soleplate of electric iron, lower push rod melts, overheat protector push rod is declined, lower safety plate loses the bearing force of overheat protector push rod, disconnect the electrical contact of lower safety plate and sheet of insuring, disconnecting circuit, form second protection, when the inefficacy of lower push rod temperature control cannot be melted, after the fusing point that the heatable soleplate of electric iron reaches upper ejector pin by again continuing to heat up, upper ejector pin fusing makes overheat protector push rod decline, lower safety plate loses the bearing force of overheat protector push rod, disconnect the electrical contact of lower safety plate and sheet of insuring, disconnecting circuit, form three protections, finally avoid that electric iron is overheated to be burnt out, too high the scalding of heatable soleplate intensification ruins clothing, prevent fire.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5; upper ejector pin 121 can also do following accommodation with the manufactured materials of lower push rod 122; the upper ejector pin 121 of described overheat protector push rod 12 and lower push rod 122 are meltability engineering plastics and make; therefore upper ejector pin 121 and lower push rod 122 can melt equally, make it have three protections.
As shown in Fig. 3, Fig. 5, the upper end of described lower push rod 122 is provided with drop down hole c, described drop down hole c and spherical pore 122a connects, the bottom of the bulb 121a of the lower end of upper ejector pin 121 is directly connected on drop down hole c, that is to say that the bulb 121a of the lower end of upper ejector pin 121 withstands on drop down hole c, when lower push rod 122 is melted, the bulb 121a helping the lower end of upper ejector pin 121 falls among drop down hole c, upper ejector pin 121 is declined more timely, disconnecting circuit more timely.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, described register stator 3, first porcelain ring 4a, input chip 5, to insure sheet 61, second porcelain ring 4b, lower safety plate 62, movable contact spring 7, 3rd porcelain ring 4c, static contact 8, output chip 9, 4th porcelain ring 4d and bimetal leaf 10 are arranged on joint pin 1 successively, and such design makes the overall structure of electric iron temperature controller compacter, volume is less, temperature control is accurate, joint pin 1 wherein between bimetal leaf 10 and the 4th porcelain ring 4d is provided with overheat protector push rod spacer 18, described overheat protector push rod spacer 18 is provided with through hole 18a, overheat protector push rod can be limited to operating position by overheat protector push rod stator 18 through through hole 18a up and downly, that is to say that overheat protector push rod 12 is up and down only among through hole 18a, and overheat protector push rod 12 can not be translated into by the spacing of through hole 18a, wherein input chip 5 and the one-body molded design of sheet 61 of insuring, static contact 8 and the one-body molded design of output chip 9, one-body molded design makes parts reduce, conduction property more, crown cap 12a is established at the top of upper ejector pin 121, lower safety plate 62 is provided with lower safety plate recess 6a, top cap 12a is greater than the through hole 18a of overheat protector push rod spacer 18, can not drop among through hole 18a after such overheat protector push rod 12 installs, top cap 12a coordinates with lower safety plate recess 6a's, makes to hold better effects if, thus sheet 61 of insuring is also better with the abutting contact effect of lower safety plate 62.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5; the fusing point of described upper ejector pin 121 is higher than the fusing point of lower push rod 122; after guaranteeing that lower push rod 122 melts; upper ejector pin 121 melts again; thus accurately orderly control circuit, certain upper ejector pin and lower push rod can melt simultaneously, also can first melt by upper ejector pin; melt after lower push rod, effective overheat protector can be played to electric iron.
