Abstract
A garden tool includes a gasoline engine and a power source, the gasoline engine including a fuel supply system and an ignition system. The garden tool may further include a control system with at least one sensor used for collecting a working condition signal of the gasoline engine and a controller used for receiving the working condition signal and controlling the fuel supply system and/or the ignition system according to the working condition signal received. The power source may provide a power supply for the fuel supply system, the ignition system, and the control system through the controller.
Claims15
A garden tool comprising:
- a gasoline engine including a fuel supply system and an ignition system;
- a control system including at least one sensor used for collecting a working condition signal of the gasoline engine and a controller used for receiving the working condition signal and controlling the fuel supply system and the ignition system according to the working condition signals received, the control system further including an operator used for being physically operated by a user to issue a user command signal, and the controller receiving the user command signal and performing at least one of the following control actions on the gasoline engine:
- starting, flameout, and adjusting a fuel supply amount based on the user command signal received;
- and
- a starting system including a starter motor, a speed reduction unit, and a clutch unit, the gasoline engine further including a crankshaft;
- wherein when the gasoline engine is started, the starter motor drives the crankshaft to rotate through the speed reduction unit;
- wherein the clutch unit is used for one-way transmitting torque of the starter motor and is disposed between the speed reduction unit and the crankshaft;
- wherein the speed reduction unit is a gear set including an input gear, an output gear, and at least one transmission gear disposed between the input gear and the output gear;
- and
- wherein when the gasoline engine is started, an output shaft of the starter motor drives the input gear to rotate at a same speed, the input gear and the output gear meshes with each other and perform a speed reduction movement, and the output gear drives the crankshaft to rotate at a same speed through the clutch unit.
