Novel household electric iron

Abstract

The invention discloses a novel household electric iron which consists of a temperature regulating knob, a lifting bolt, an insulated bracket, an elastic copper sheet, contacts, an electric heating wire, dual metal sheets and a metal bottom plate, wherein the temperature regulating knob is connected to the lifting bolt, and arranged on the insulated bracket in a penetrating mode; the insulated bracket is connected to the elastic copper sheet; the contacts are connected to the elastic copper sheet; the dual metal sheets are connected to the electric heating wire and connected to the lower end of the insulated bracket; the metal bottom plate is placed at the lowest end. During use, a power supply is firstly switched on; at the normal temperature, the upper and lower contacts are in contact with one another; but when the temperature reaches a certain value, the dual metal sheets are heated to expand due to an extremely high temperature; the upper and lower metal sheets are different in expansion coefficient, the expansion coefficient of the upper metal sheet is relatively great, and the expansion coefficient of the lower metal sheet is relatively small, so that the dual metal sheets are downwards bent and the contacts are separated. Therefore, the power supply is switched off to stop heating; after the temperature is lowered, the dual metal sheets are got back to the original shapes, and the circuit is re-accessed to heat in a circulating mode to achieve the effects of automatically controlling the temperature.

Description

technical field [0001] The design of the present invention is an electric iron, especially a novel household electric iron. Background technique [0002] Electric irons currently on the market are very expensive and bulky, not suitable for families to buy and use, and it is not very convenient to use, and even some families cannot afford the high cost of buying electric irons; in addition, once damaged, it is difficult to repair the electric iron .
