Detailed description of the invention
A kind of electric iron temperature controller as shown in Figure 1, Figure 2, Figure 6 shows; comprise joint pin 1, spiral register 2, register stator 3, some porcelain rings 4, input chip 5, the sheet 61 of insuring, lower safety plate 62, movable contact spring 7, static contact 8, output chip 9, bimetal leaf 10, porcelain rice 11 and overheat protector push rod 12; spiral register 2 is arranged on register stator 3; bimetal leaf 10 is fixedly connected in electric iron heatable soleplate, and the present embodiment drives porcelain rice 11 to control between movable contact spring 7 and static contact 8 by bimetal leaf 10 to electrically contact.By the sheet 61 of insuring, lower safety plate 62, the fixture 18 of overheat protector push rod 12 and overheat protector push rod forms the overheat protector safeties of temperature controller, insure sheet 61 and lower safety plate 62 one end respectively fixedly sleeved on joint pin 1 porcelain ring 4 upper-lower positions, the other end of sheet 61 and lower safety plate 62 of insuring is respectively free end, overheat protector push rod 12 is supported between heatable soleplate and lower safety plate 62 free ends, described overheat protector push rod 12 is one to have definite melting point the fusible working of plastics of integrated insulation, it comprises abutting part 12a, the cylindricality lower support 12b of portion, be positioned at the cylindricality lower support 12b of portion middle and lower part and with the integrated flange collar 12d of overheat protector push rod 12.Described electric iron heatable soleplate is provided with storage tank 16; described overheat protector push rod 12 is supported in the top upper end of storage tank 16 by flange collar 12d; the bottom of overheat protector push rod 12 is with a certain distance from storage tank 16 bottom lands; the upper end pushing tow of overheat protector push rod 12 is in lower safety plate 62 free ends, and lower safety plate 62 free ends are subject to 12 supports of overheat protector push rod to electrically contact normally closed connection with sheet 61 free ends of insuring.The top upper end of the present embodiment storage tank 16 is the basic side of heatable soleplate.
The maximum outside diameter of described flange collar 12d is greater than the internal diameter of storage tank 16; and the vertical range of flange collar 12d and overheat protector push rod 12 bottoms is less than the degree of depth of storage tank 16; make overheat protector push rod 12 and have certain distance in storage tank 16 and between storage tank 16 bottom lands, the upper end pushing tow of overheat protector push rod 12 is in lower safety plate 62 free ends.Lower safety plate 62 free ends are subject to 12 supports of overheat protector push rod to electrically contact normally closed connection with sheet 61 free ends of insuring.The PET plastics one mold compacting that the overheat protector push rod 12 of the present embodiment is 310 DEG C-340 DEG C by melting temperature forms; it is with respect to greatly reducing as dystectic metal meltability material costs such as tin; processing technology is also more ripe convenient, and can made with high precision realize.Under the temperature environment of these PET plastics below 300 DEG C, its stability and durability are very strong, make temperature controller of the present utility model compared with existing temperature controller simultaneously, and the life-span is more permanent.The direct butt of flange collar 12d of overheat protector push rod 12 middle and lower parts is supported in electric iron heatable soleplate, and overheat protector push rod 12 temperature-sensitives fast, directly, can be made corresponding action more timely, make temperature controller more sensitive.The in the situation that at electric iron, overheated and bimetal leaf temperature control losing efficacy, temperature exceed design temperature also cannot the condition of disconnecting circuit under, when electric iron heatable soleplate temperature exceedes the fusing point of overheat protector push rod 12, directly be connected to the overheat protector push rod 12 flange collar 12d fusings of instant temperature-sensitive in electric iron heatable soleplate, the height of overheat protector push rod 12 declines, the free end of lower safety plate 62 loses the bearing force of overheat protector push rod 12, lower safety plate 62 departs from and the contacting of the sheet 61 of insuring under the effect of self deformation recovery power, thereby disconnecting circuit, effectively prevent electric equipment products temperature from continuing to rise and cause the danger such as fire.Because overheat protector push rod is formed in one; with respect to other overheat protector safeties; the utility model is simple in structure; overheat protector push rod can directly assemble and settle at one go; processing technology step and the time of temperature controller are greatly shortened; difficulty of processing and cost are also decreased, more avoided assembling wearing and tearing and fitness problem between multicompartment, the precision and stability of temperature controller is able to good guarantee.
Storage tank 16 except the design as shown in Fig. 2 the first embodiment, also can adopt the design as shown in Fig. 3, Fig. 4, Fig. 5 in electric iron heatable soleplate.
As shown in Figure 3, second embodiment of storage tank in heatable soleplate, heatable soleplate is provided with sinking installing hole 20, storage tank 16 is arranged at the below of sinking installing hole 20 and is communicated with sinking installing hole 20 bottoms, the top upper end of storage tank 16 is bottom surfaces of heatable soleplate sinking installing hole 20, these storage tank 16 upper ends are lower than the basic side of heatable soleplate, and flange collar 12d external diameter is less than or equal to the internal diameter of sinking installing hole 20.Make flange collar 12d go deep into heatable soleplate inside, temperature-sensitive heatable soleplate more accurately, the situation of avoiding heatable soleplate surface temperature to cause the action of overheat protector safeties to postpone lower than storage tank 16 temperature.
Shown in Fig. 4, Fig. 5; three, four embodiment of storage tank in heatable soleplate is respectively that the bottom centre of the storage tank 16 in electric iron heatable soleplate on the basis of first, second embodiment of heatable soleplate sets recessed depressed part 16a; overheat protector push rod 12 declines that are designed to of depressed part 16a bring larger height; simultaneously also for the liquid plastic after fusing provides space; after ensureing 12 fusings of overheat protector push rod, can decline rapidly, the reaction of overheat protector safeties is more sensitive.
More rapid melting of flange collar 12d when making temperature reach the fusing point of overheat protector push rod 12; simultaneously cost-saving again; overheat protector push rod 12 can adopt the another kind of embodiment design of overheat protector push rod 12 as shown in Figure 7; flange collar 12d extends outside and forms several feets, and several feets distribute along flange collar 12d even circumferential.Feet is more tiny, fewer its temperature susceplibility of quantity is very high, is also more suitable in requiring limiting temperature that temperature controller is cut off the electricity supply to be worth the electrical equipment of limit on the lower side.Be preferably on the top upper end of storage tank 16 and can be evenly distributed with the feet groove corresponding with several feets (not indicating in figure), further to improve the stability of strutting system of overheat protector push rod 12.
