Abstract

The invention provides a high-frequency inverter power supply equipped with a protection mechanism, comprising an inverter power supply inner shell device, an outer shell device, a top cover device and a movable device, an outer shell device is arranged behind the inverter power supply inner shell device, and the outer shell device includes The shell, the shape of the shell is U-shaped, the rear end of the shell is fixedly connected with the rear plate, the front surface of the rear plate is provided with a through hole, the inside of the through hole is fixedly connected with the air valve, the front end of the air valve is fixedly connected with the air bag, the air The valve communicates with the inside of the airbag, the upper end of the airbag is fixedly connected with a one-way air valve, the one-way air valve is a telescopic connection structure, the upper end of the shell device is provided with a top cover device, and the top cover device includes a top cover lower plate. In the present invention, when a fire breaks out, the air bag deflates and shrinks, and then the movable device and the inner casing device of the inverter power supply are quickly pulled back into the outer casing device for protection through the pull of the second spring and the third spring, which improves the self-protection of the inverter power supply ability.

Description

technical field [0001] The invention relates to the technical field of high-frequency inverter power supply, in particular to a high-frequency inverter power supply equipped with a protection mechanism. Background technique [0002] The inverter is a converter that converts DC power (battery, storage battery) into constant frequency and constant voltage or frequency modulation and voltage modulation AC (generally 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. Widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVD, VCD, computers, TVs, washing machines, range hoods, refrigerators, VCRs, massagers, fans, lighting, etc. [0003] At present, most of the high-frequency inverter power supplies on the market do not have self-protection performance, especially in case of fire and other situations, the high-frequency inverter power supply cannot carry out certain self-protection without...
