Abstract
The utility model discloses a new style brazing tool, in particular to a temp. Adjustable constant temp. Electric iron, comprising a pyrometer, bimetallic strips and a temperature adjustable turn button which are added on an ordinary electric iron. When working, the space position of the temperature distortion bimetallic strips is controlled by the temperature adjustable turn button, causing the bimetallic strips to achieve supply interruption as heat distortion and energizing as cold restoration to keep the desired constant temperature point for working. The utility model has the advantages of safety, energy saving and convenient use.
Description
The novel braze welding instrument of a kind of energy-saving safety of adjustable thermostatic electric iron.
In the work brazing process, the electric iron that melts soldering tin is used is to utilize the solder horn that is heated by heating to carry out work, because the heat of heating was directly proportional with its time by electric current, time is long more hot more, the solder horn temperature can not be controlled, and promptly dangerous, damage device has been wasted the energy again.Adopt the solder horn of flatiron radiator or various special-purpose materials both at home and abroad ... method, but all can not deal with problems.
Task of the present invention provides a kind of novel electric iron, and it can cut off the power supply when temperature is high automatically, and heating is no longer heated up, and can connect power supply automatically when temperature is low, and heating is heated up.Automatically the operating temperature of control electric iron is safe and energy-conservation.
Task of the present invention is finished as follows, on the solder horn of connection heating a small-sized high temperature thermometer and a bimetal leaf is housed, power supply is followed in the other end of bimetal leaf, locus with knob control bimetal leaf, the temperature of solder horn directly is reflected on the thermometer during work, when rising to when temperature required, turn adjusting knob, bimetal leaf moves, power supply breaks away from disconnection, bimetal leaf two sides tympanites coefficient difference, temperature distortion during disconnection, because heating outage, solder horn begins cooling, and bimetal leaf turns cold simultaneously, circuit was connected again when distortion returned to definite shape.So heating heats up, the continuous like this control temperature purpose of energy saving that reaches repeatedly.
The present invention is described in further detail below in conjunction with accompanying drawing.
The longitudinal sectional drawing of Fig. 1 structure of the present invention
Fig. 2 electrical schematic diagram of the present invention
Be fixed on the protective metal shell 6 by temperature meter base bronze gong silk 2 with reference to Fig. 1 solder horn 1, the measuring junction of high temperature thermometer 3 is inserted in the special pit of temperature meter base bronze gong silk 2, the other end is fixed on the insulated handle 12 inactive by gong silk 4, the temperature of solder horn 1 directly is reflected on the high temperature thermometer 3 by bronze gong silk 2 like this, protective metal shell 6 is fixed on the jacket seat 7, one seam is arranged on the jacket seat 7, bimetal leaf 8 is housed in the seam, the inner layer expansion coefficient of bimetal leaf 8 is greater than skin, it is outwardly-bent to meet heat, one end of bimetal leaf 8 is fixed on the protective metal shell 6 with gong nail 8a, the other end is that free end is with resin securing electric lines 13, with the space length of knob 9 promotion bimetal leafs 8 at control electric wire 13 and binding post 10.Electric wire 13 other ends by indicator lamp 14 be connected with power line 15, indicator lamp 14 is contained on the handle 12, electrical bar 5 is contained in the protective metal shell 6.The heat of electrical bar 5 passes to electric soldering bit 1 by protective metal shell 6 during work, on high temperature thermometer 3, the bimetal leaf 8.When the temperature arrival of solder horn 1 needs, can find out from thermometer 3 directly that turn knob 9 and make the electric wire 13 of bimetal leaf 8 one ends break away from binding posts 10, power supply disconnects indicator lamp 14 and extinguishes; Electrical bar 5 temperature descend, protective metal shell 6 and solder horn 1, the temperature of bimetal leaf 8 descends thereupon, the temperature of bimetal leaf 8 descends and meets thermogenetic outwardly-bent deformation recovery, electric wire 13 is drawn close to binding post 10, when temperature drops to certain limit, electric wire 13 is run into binding post 10, energising, indicator lamp 14 is bright, electrical bar 5 temperature rise, reach solder horn 1 by protective metal shell 6, bimetal leaf 8, it is outwardly-bent that bimetal leaf 8 is met heat, when actual temperature surpasses the adjusting temperature, bimetal leaf 8 bendings make electric wire 13 break away from binding post 10, outage, indicator lamp 14 goes out, electrical bar 5 temperature descend, the solder horn temperature descends thereupon, has so realized the automatic constant-temperature control of electric iron repeatedly.The present invention is easy to use, energy-saving safe.
Embodiment, the weldering wiring board plugs in, be raised to 260 when spending (observing) according to need of work in solder horn 1 temperature from high temperature thermometer 3, temperature adjustment knob 9 is regulated from high to low till outage, indicator lamp 14 extinguish, vernier knob 9 then, transfer to indicator lamp 14 and be in the point of interface that flickers, electric iron will keep 260 degree constant temperature to start working.
Claims (2)
1, novel braze welding instrument adjustable thermostatic electric iron of forming by solder horn 1, high temperature thermometer 3, electrical bar 5, bimetal leaf 8, thermoregulation knob 9, binding post 10, electric wire 13, it is characterized in that: bimetal leaf 8 one ends connect electric wire 13 and keep certain distance with binding post 10, and the other end is close to electrical bar 5.
