Ignition device of small gasoline engine generator

Abstract

The invention relates to an ignition device of a small gasoline engine generator. The ignition device comprises a rotor and a gasoline engine box body. The rotor is mounted in the gasoline engine box body. The ignition device is characterized in that small magnetic steel is embedded in the outer side of the circumference of the rotor; a Hall element inductor is mounted at the position, corresponding to the small magnetic steel, of the inner side of the gasoline engine box body; and the small magnetic steel and the Hall element inductor cooperate to generate induction signals used for controlling an ignition system of a gasoline engine to carry out ignition. According to the ignition device, the small magnetic steel is embedded in a rotor shell body; the Hall element inductor is mounted at the corresponding position of the gasoline engine box body, when the rotor operates till the small magnetic steel coincides with the Hall element inductor, the Hall element inductor can generate an ignition signal, and therefore the aim of controlling ignition is achieved; and due to the fact that the size of the small magnetic steel and the size of the Hall element inductor are small and the small magnetic steel is embedded in a rotor shell, no size is occupied, no wind is blocked, and the ventilating and cooling effects are good.

Description

Technical field [0001] The invention provides an ignition device for a small gasoline generator, which is mainly used for a small gasoline permanent magnet outer rotor generator and belongs to the field of power machinery. Background technique [0002] At present, most gasoline engines use magneto technology for ignition, and small gasoline generators use trigger technology, that is, a small boss is stamped on the circumference of the rotor shell, and a trigger is fixed at the corresponding position of the gasoline chassis. When the rotor is running , The small boss on the shell induces a signal when it passes the trigger, and this signal can be used to control the ignition system. Since the small boss and the trigger have a certain volume, they need a certain installation space, and they are all installed in the generator ventilation duct, which not only takes up a lot of space, but also easily blocks the wind, which affects the direction of the cooling wind, and the ventilation...

AI Technical Summary

Problems solved by technology

Since both the small boss and the trigger have a certain volume, they require a certain amount of installation space, and they are installed in the ventilation duct of the generator, which not only takes up a lot of space, but also is easy to block the wind, affecting the direction of the cooling wind, and the ventilation and cooling effect is poor.
