The invention provides a device and technology for solving a short-circuit hazard and ensuring the circuit safety of a range hood. The technology is characterized by actually comprising practical technologies 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 is used for continuously switching on and off in an alternating current circuit. According to the technology, the output point of a current transformer is changed to be powered by a current source, the keychange facilitates that the power supply of a control circuit is not influenced by short circuit or overcurrent of a load, and the power of the power supply is more sufficient when the load is subjected to short circuit or overcurrent, so that the short circuit and overcurrent protection is ensured to be timely and effectively controlled. When the range hood is short-circuited, a breakpoint switchis immediately started to provide a power supply for an alternating current switch controller, a focus-free alternating current switch is directly controlled to control the alternating current, no electric spark is generated during switching, and no electric spark is generally generated at the short-circuited position when the short circuit occurs, 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 range hoods, and proposes a device and technology for solving the short-circuit hazard of the range hood and ensuring the safety of the 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 industry. Th...
