Technical field
The present invention relates to a kind of venting gas appliance of oil-engine driven manual Control work equipment.
Background technique
The manual working equipment of control is for example pruned shear, free cutter, chain saw or similar devices that hedge uses by internal combustion engine drive, and the loss in design usually of this internal-combustion engine is lubricated.Especially when using the design of two-cycle engine, include a spot of lubricating oil family in the fuel/air mixture in introducing motor, this lubricating oil family is through being guided the external world with the form of mist with the exhaust flow of generation after the motor.Except above-mentioned mist of oil, residue of combustion, atmospheric moisture or similar substance also may form fog, and this phenomenon also can be seen in the four-stroke motor.
Clearly, the above-mentioned substance in the exhaust flow tends to form one deck coagulant film on the internal surface of venting gas appliance.Can see that in the certain structure form coagulant film transmits on the direction of exhaust flow.Can form to condense in the exhaust end zone of flue gas leading and converge thing, this condenses and converges thing and drip at exhaust end, perhaps even at the outer side surface of outlet pipe refluxes to the direction of motor.This causes irritating pollution, thereby is necessary frequent cleaning equipment.
Summary of the invention
Task of the present invention is exactly to improve the venting gas appliance of aforementioned type, thereby avoids occurring polluting.
This task realizes by following venting gas appliance.
According to the venting gas appliance that the invention provides a kind of oil-engine driven working equipment, comprise the outlet pipe that is used for exhaust flow, wherein outlet pipe is in communication with the outside by exhaust end.The inwall of outlet pipe be provided with make that the air-flow cross section narrows down, around the coagulant induction element.Outlet pipe is connected on the exhaust silencer back, and wherein the coagulant induction element is positioned at the area under control Duan Chu of exhaust silencer outside.
The coagulant induction element in a circumferential direction around structure stoped the motion of coagulant film on the exhaust flow direction.The coagulant induction element extends radially inwardly from the inwall of outlet pipe.The coagulant that accumulates or deposit on exhaust wall gets up and is radially inwardly turned in this zone inner accumulated.Simultaneously because the coagulant induction element extends radially inwardly, around the coagulant induction element make freely that the air-flow cross section narrows down.The speed of exhaust flow is this local raising.Because the flow velocity degree of exhaust flow has improved, coagulant that accumulate and inwardly guiding is carried and is transported to the external world.Avoided coagulant from outlet pipe, to ooze.
In another advantageous modification, after outlet pipe was connected an exhaust silencer, wherein the coagulant induction element was arranged in the area under control section outside the exhaust silencer.Outlet pipe area under control section does not outside have the waste gas circulation of heat.Cold relatively environment helps coagulant and forms.The setting of coagulant induction element in this zone caused the condensation in the exhaust flow almost directly to remake usefulness in the place that coagulant forms.Also just avoided the danger of more coagulant accumulation and consequent formation drop reliably.
The coagulant induction element is advantageously provided in the upstream end that is directly adjacent to exhaust end.Hindered and led the condensation regelation or the deposition of getting back in the exhaust flow.
In a preferred embodiment, the coagulant guiding device forms the separation point of an exhaust flow on its cross section.Be not limited to the corner angle shape at angle in the notion of the separation point of this selection.It comprises that all can make the flow area of outlet pipe narrow down, and produces the aerodynamic shape of follow-up formation vortex ground from the airflow breakaway effect of surface isolation with the different energy of the sharp formation of venturi.The flow profile of coagulant induction element and follow-up vortex form the effect of carrying outside of the exhaust flow on the coagulant film that has promoted the wall side.
The coagulant drop of rolling has been brought to the near axis area of the inside of exhaust flow, and this makes, and the new deposition of generation becomes difficult on the tube wall of back.
In a suitable improvement project, the coagulant induction element extends along the spiral inner wall shape of outlet pipe.Axially extended helix shape allows to condense in the deposition of wall side in limited degree coagulant film moves vertically, and then distributes extending axially on the part of coagulant induction element.If coagulant distributes on the length of coagulant induction element, the coagulant induction element can more effectively be led the coagulant of deposition and be got back in the exhaust flow.When physical dimension hour, the spiral quantity required for enough guiding function is threaded between six spirals at two, wherein preferably has the embodiment of four spirals.
In an advantageous embodiment, the coagulant induction element imports in the outlet pipe medial axis zone with its downstream.Not led the residue coagulant of getting back in the exhaust flow on coagulant induction element structure length flows up to the downstream that arrives the coagulant induction element at coagulant induction element place along exhaust gas flow direction.Wherein, these coagulants are directed into the medial axis zone that can be admitted and derive by exhaust flow better.Remaining coagulative formation has just been avoided.
In rational embodiment, the coagulant induction element is made spiral helicine wire spring form.It is effectively that the line cross section is made round-shaped, both for the logistics of condensing of collecting deposition also in order to form the ground drainage with the exhaust flow vortex.This favourable effect also is accompanied by simple and inexpensive structure mode.
Preferably the upstream extremity of wire spring radially bends inwards.This line end that bends inwards simply mode is used as the assembling supplementary structure.Simultaneously, thus this line end that is projected into the air-flow cross section is used to form vortex readmits coagulant better.
In advantageous embodiment, wire spring radially is fixed in the outlet pipe to pre-tensioning.Radially pre-tensioning is fixed except producing reliable position, also causes the impacting force between spring and the inwall.In this zone, it should be noted that seal action.The coagulant film can not see through between wire spring and the tube wall.In addition, the coagulant film is radially inwardly turned to by the line cross section round wire spring, wherein re-enters the characteristic optimum of exhaust flow.
