Further, the big end of described piston rod part is provided with and gets rid of oil skip, described lubricating oil splash duct be positioned at get rid of oil skip get rid of oil splashing scope; Get rid of oil skip (oil-throwing rod) and belong to the common components of put-put, belong to prior art, do not repeat them here; Lubricating oil splash duct be positioned at get rid of oil skip get rid of oil scope (such as getting rid of the motion tangent line of oil skip), be beneficial to and make more lubricating oil enter rocking arm installing space, form lubrication and cool down.
Further, described lubricating oil splash duct is directly through to rocking arm installing space; Directly run through and namely form straight hole, be more conducive to lubricating oil and directly splash to required lubricant housings, simple in construction, lubrication and good cooling results.
Further, described lubricating oil splash duct is passed through between hole at inlet valve push rod by hole and exhaust valve push rod; Owing to the installation of rocking arm is corresponding with the position of inlet valve push rod and exhaust valve push rod, the lubricating oil splashed by lubricating oil splash duct is more conducive to act on rocking arm, forms efficient lubrication; Inlet valve push rod is existing structure by hole and exhaust valve push rod by hole, does not repeat them here.
Further, header structure sized by the cross section in described lubricating oil splash duct, the major part of described concentric reducer structure is avoided inlet valve push rod and is formed by extending to both sides behind hole by hole and exhaust valve push rod; Concentric reducer structure includes T-shaped structure, trapezium structure, triangular structure or by the one large one small structure of smooth curved transition; The microcephaly of this concentric reducer structure passes through, between hole, to avoid backward both sides and expand gradually by hole and exhaust valve push rod at inlet valve push rod, and both sides refer to passes through hole and the orientation by hole of the exhaust valve push rod to inlet valve push rod respectively, does not repeat them here.
Further, the major part of described concentric reducer structure corresponds to cylinder body side, and this structure can strengthen the lubricating oil splash amount that rocking arm is overall further, and meanwhile, this major part also corresponds to inlet and exhaust valve splash lubrication oil, and cooling and lubricant effect are better.
Further, described electromotor is vertical type general-purpose petrol engine.
Further, described lubricating oil splash duct is upper and lower straight hole, is more conducive to passing through of lubricating oil, and ensures backflow.
Further, described concentric reducer structure is be made up of structure ascending gradually smoothed curve, it is to avoid stress is concentrated, and can make full use of inlet valve push rod by hole and exhaust valve push rod by the space between hole, increases lubricating oil splash amount.
Beneficial effects of the present invention: the electromotor of the present invention, adopt the structure in the lubricating oil splash duct being communicated with between the rocking arm installing space of crankcase and cylinder assembly on crankcase, the lubricating oil splashed in crankcase enters rocking arm installing space by this duct, can be formed and the cylinder head movement parts such as rocking arm, valve is carried out sufficient lubrication and cooling, do not change the circulation route of lubricating oil, the Fast Wearing avoiding rocking arm and valve and the carbon distribution caused due to high temperature, extend the service life of rocker arm assembly.
