Abstract

The invention relates generally to portable internal combustion engine powered devices. Public a small engine control combination switch comprising a knob assembly, a bracket and a choke cable, knob assembly includes a fixed plate, characterized in that the fixed plate with a rail; the bracket including a first hole. The choke cable connects with the rail through the first hole. The height of the rail is gradually increased, rail pivot drives the choke cable on the top of the track moves up and down; also further includes a fuel switch, a fixed plate is provided with a rotating shaft, the shaft connecting the fuel switch. The invention through the choke point of engine control, start-up, operation and shut down control, which simplifies the traditional steps of engines, generators and other equipment, greatly simplifying the operation process, improving the operation efficiency.

Claims

1. A small engine control combination switch, comprising:

a fuel switch;

a bracket having a first hole and second hole;

a knob assembly comprising a fixed plate, a rotating shaft which passes through the second hole to connect with the fuel switch for driving the fuel switch on or off;

a engine controlling means comprising a convex block on the fixed plate, an ON/OFF switch arranged on the bracket, the ON/OFF switch is matched with the convex block to control the engine;

a coke controlling means comprising a rail on the fixed plate, a choke wire guide is provided on the bracket, a choke cable is in the choke wire guide and passes the first hole to contact with the rail, a reset spring is installed at an end of the choke cable for making the end of the choke cable to keep touch on the rail, the rail is gradually increased in height, when the fix plate of the knob assembly is turned the rail is turned too, thereby the rail drives the choke cable to move up and down to control the coke;

the Bracket is provided with a panel and the knob assembly is set within the panel 10, panel 10 is marked labels of Start, Run, Run Out of Fuel and Stop;

when the knob assembly is in the Start position, the fuel switch 5 has been partially open, the choke in a fully closed state, the ON/OFF switch 9 is off state;

when the knob assembly is within a scope from the Start to Run, the fuel switch and the choke gradually opened to the maximum position, arbitrary positions within this range;

when the knob assembly is in the Run position, the choke and fuel switch fully open;

when knob assembly is in the Fuel Shut-off position, the fuel switch is fully closed, the choke valve remains fully open, the engine continues to run, carburetor fuel is burnt, thus avoiding use of tools to manually put the carburetor fuel out;

when the knob assembly is in the Stop Position, the ON/OFF switch is contacted by the convex block to be turned on to make the engine flameout.

2. The small engine control combination switch according to claim 1, wherein with a stopper plate is on the fuel switch, a spring is arranged on the stopper plate, a steel ball is arranged on the spring, a plurality of grooves are in the fixed plate, which are matched with the steel ball respectively, and an outer diameter of the steel ball is larger than a pore diameter of the groove.
