Description

Multipotency safety electric iron

The utility model belongs to the electrical heating instrument, particularly can conveniently peg graft and change heating and change no inductance flatiron and plastics package instrument and the thermotherapy instrument that various welderings are chewed.

Along with popularizing of intelligent electrical apparatus, when the electric equipment products of band integrated package are particularly keeped in repair in assembling, conventional electric iron produces magnetic field and association inductance because heating is coiled type, understand puncture or damage integrated package and progressively dwindle market, the no inductance flatiron that replaces it is progressively popularized market, no inductance flatiron is common four kinds of products, a kind of is the no inductance flatiron of the instrument (being called welding stage) of the extrapolated subsidiary elimination inductance of state, has step-down, rectification, the current stabilization function, but complete unit reaches greatly more than 2 kilograms owing to welding stage weight, except that carrying inconvenience, price is too high, and this no inductance flatiron is in order to make full use of the instrument (welding stage) that can eliminate inductance, go up configuration two the flatiron of different capacity at an instrument (welding stage), about 3200 yuan of retail prices, average every about 1600 yuan, be not suitable for China's actual conditions; Another kind is to use the no inductance flatiron of PTC temperature-sensitive heating, and having utilized the PTC temperature-sensitive element is a kind of cubic heat source and the coil prerequisite principle that do not had to produce inductance becomes no inductance flatiron, and the PTC flatiron is light and handy, price is low, and shortcoming is that the electric current variation reaches 10 greatly ⁵And it is low when high when making the heat capacity of solder horn owing to the reason of curie point restriction electric current, therefore it is inconvenient that PTC does not have the use of inductance flatiron, though appear on the market for many years but sales volume is little: another is that the flatiron that utilizes disposable lighter to make the flame secondary temperature elevation has been invented in Taiwan, owing to do not make electricity consumption, therefore there is not inductance, but the flame heating is dangerous, and the scope of application is restricted; Domestic priority discloses about 200 kinds of utility model patents that relate to flatiron, wherein the patent No. is 98202437.1, name is called " little electric heating safety flatiron " and has used the Electric radiant Heating Film plane heat source, comprehensive advantage such as reached light and handy, no inductance, speed is hot, energy-conservation, price is also low still one can only be suitable for a kind of voltage source work to flatiron; Aforesaid various flatiron, all has only single welding function, and all have a kind of common fault: heating must be connected with external power by two electrode outlet lines, when assembling or maintenance,, the shell handle adopt screw-type to screw fixing usually because connecting, make two electrode wires be difficult to be in parastate work and two electrode outlet lines are come off under the torque effect even break, not only therefore cause electric iron to damage, and it is bigger to start to keep in repair the difficulty that electrode wires is resetted, and particularly takes off two electrode wires of having no progeny and also might touch and cause short circuit accident.

The utility model discloses a kind of multipotency safety electric iron that can movable grafting Electric radiant Heating Film porcelain tube element, chews by the weldering that is convenient for changing the pluggable Electric radiant Heating Film disjunctor porcelain tube element that is suitable for different parameters and changes various difference in functionalitys to make a flatiron can all can not have the welding of inductance safety simultaneously under the environment of 220V, 110V, 36V, 24V, 12V (automobile storage battery), 6V different electrical power such as (dry cells) and increased that pyrocondensation is moulded or functions such as involution plastic bag packaging function and thermotherapy.
