(including pull rope, start handle, spring, pull plate, limit block, start cup, etc.), the side wall and bottom surface of the pull plate cover are provided with air inlets, and the manual start pull plate cover is covered on the engine On the air inlet of the air guide cover, a fan is housed in the engine air guide cover. The inverter includes an inverter cover and an inverter electronic unit. The inverter electronic unit is installed in the inverter cover. The inverter does not have a separate cooling structure, but the inverter cover is hoisted on the On the rack in front of the pull-up cover, there is a distance between the pull-up cover (and it is also installed in other places), so that the airflow can pass through the inverter under the action of the fan in the engine air guide cover. The inverter is cooled, but because there is a distance between the inverter cover and the pull plate cover, most of the airflow enters the engine air guide cover through the gap between them. In actual use, the cooling effect on the inverter is poor . In addition, at present, the inverter cover and the pulling plate cover are installed separately, so there are many parts, high manufacturing cost, long unit length and uncompact structure.
