The invention provides a device and technology for solving a short-circuit hazard and ensuring the circuit safety of an electric iron. The technology is characterized by actually comprising practicaltechnologies in two aspects, one is a two-wire alternating current control switch technology which mainly plays a role in switching on and off, and the other is a switching circuit technology which isused for continuously switching on and off in an alternating current circuit. Meanwhile, the output point of the current transformer is changed to be powered by a current source, the key change facilitates that the power supply of the control circuit is not influenced by short circuit or overcurrent of the load. When the electric iron is short-circuited, a breakpoint switch is immediately startedto supply power to an alternating current switch controller, a focus-free alternating current switch is directly controlled to control the alternating current, and electric sparks are generally not generated during the switching or short circuit, so that the occurrence rate of electrical fire disasters is greatly reduced.
Description
[0001] 1. Technical field [0002] The invention relates to the design field of an electric iron, and proposes a device and technology for solving the short circuit hazard of the electric iron and ensuring the safety of its circuit. [0003] 2. Background technology [0004] The invention and use of electricity has brought great changes to people's production and life. The widespread use of electricity has driven lasting and profound structural changes in production. Electricity gradually replaced steam. In the 1870s, as new electricity entered the production field as a new energy source, it became the main power of factory machines, and human history entered the "Electrical Age". Due to the use of electricity, other industrial sectors have also developed rapidly, especially the development of the steel industry, which has made mankind bid farewell to the "cotton era" in the field of materials. Electrification and the advent of the "Steel Age" marked the rise of modern indus...
