DETAILED DESCRIPTION OF THE EMBODIMENT

[0022] Reference is made to the accompanying drawings in which is shown an illustrative embodiment of the invention from which its features and advantages will be apparent.

[0023] An embodiment of the invention

[0024] A small engine control combination switch shown in FIGS. 1-4 knob assembly 1, bracket 2 and choke cable 4, knob assembly 1 includes fixed plate 104, characterized in that fixed plate 104 with rail 101; and bracket 2 including first hole 201. Choke cable 4 through first hole 201 connected with rail 101, The height of the rail 101 is gradually increased, rail 101 pivot drives choke cable on the top of the track moves up and down. Also further includes choke wire guide 41, choke cable 4 is in choke wire guide 41, and choke wire guide 41 is provided on bracket 2. A reset spring is installed at the end of choke cable 4 making the point of choke cable 4 and rail 101 is always kept in contact, Slide on rail 101 to realize telescopic choke cable 4, so as to control the choke opening and closing.

[0025] Also further includes fuel switch 5, fixed plate 104 with rotating shaft 102 is provided with second hole 202 on bracket 2, turn rotating shaft 102 into second hole 202, rotating shaft 102 to connect fuel switch 5, rotating shaft 102 rotates to control fuel switch 5.

[0026] Bracket 2 is provided with panel 10 and knob assembly 1 is set within panel 10, panel 10 marked Start, Run and Run Out Of Fuel and Stop font of labels.

[0027] Fixed plate 104 includes convex block 105, and ON/OFF switch 9 is arranged on bracket 2. When convex block 105 and ON/OFF switch 9 are in contact, ON/OFF switch 9 is turned on, so turn off the engine.

[0028] With stopper plate 6 on fuel switch 5, spring 7 is arranged on stopper plate 6, steel ball 8 is arranged on spring 7; groove 103 in fixed plate 104, which is matched with steel ball 8, and the outer diameter of ball 8 is larger than the pore diameter of groove 103. Rotating part 106 is arranged on fixed plate 104, rotating fixed plate 104 can increase the feeling when the user turns knob assembly 1.

[0029] Operation Process as Follows:

[0030] 1. Starting Position

[0031] When knob assembly 1 in an initial position, that is, in the Start position, fuel switch 5 has been partially open, the choke in a fully closed state, ON/OFF switch 9 is off state, rotating knob assembly 1 within the scope from the Start to Run, fuel switch 5 and the choke gradually opened to the maximum position, arbitrary positions within this range, the operator can manual or electric to start the engine motor according to environmental conditions.

[0032] 2. Operating Position

[0033] Rotary knob assembly 1 to Run position, at this time the choke and fuel switch 5 fully open, when the engine is in the operating phase.

[0034] 3. Storage Position

[0035] Continue rotating knob assembly 1, when fuel switch 5 out of fuel slowly decrease, keeping the choke fully open. When the users don't plan to use the engine for a long time, can be rotated to the Run Out Of Fuel position where fuel switch 5 is fully closed, the choke valve remains fully open, the engine continues to run, when the carburetor fuel burn, engine turn off, thus avoiding the use of tools to manually put the oil, simplifies operation.

[0036] 4. Stop Position

[0037] Continued rotation knob assembly 1 to Stop position, then ON/OFF switch 9 is contacted by convex block 105 on knob assembly 1, ON/OFF switch 9 is turned on, which causes the engine flameout, and the device stops running.

[0038] The invention overcomes the defects of the prior art, only rotating the knob assembly can realize the choke, fuel switch 5, ON/OFF switch 9 control, simplifying the operation process, improving the operating efficiency; and increases the function of burning residual fuel in the carburetor, so you do not need to manually by way of dumping, which can prevent of the engine unused for long time leading to corrosion of fuel to the carburetor, and the oil deterioration causes the blockage of the carburetor.

[0039] The principles and features of this invention may be employed in various and numerous embodiments without departing from the scope of the invention.
