Description
Technical field
The utility model relates to the air filter of a kind of two strokes and four-stroke gasoline engine, particularly a kind of control gear of being opened the air filter chock plate by the open out device.
Background technique
Small two-stroke and four-stroke gasoline engine have the characteristics such as power per liter is large, volume is little, simple in structure, cost is low, in portable instrument, use in a large number, as often using in the products such as grass-mowing machine, brush cutter, mowing machine, suction machine, pruner, chain saw, chipper, snowplow, rooter.Be in cold car state owing to motor during engine start, mixed gas can not get sufficiently preheating, gasoline evaporation difficulty, simultaneously, because the rotating speed that engine crankshaft is driven is low, thereby the air velocity that is inhaled in the carburetor throat is lower, be difficult to produce enough degree of vacuum at the trunnion place and make the gasoline ejection, both having made is to flow out gasoline from trunnion, can not be subject to the impact of strong air flow and atomizes, and the overwhelming majority is the elaioleucite state.Elaioleucite in the mixed gas can be because contact and condense on the air inlet tube wall with cold metal; can not enter cylinder with air-flow; thereby make the mixed gas in the cylinder excessively rare; can't ignite; therefore; requirement increases a chock plate before Carburetor; close chock plate; enter a small amount of air; the mixed gas that enters in the cylinder is thickened; guaranteeing that motor is started, the setting up procedure of available engine is, closes chock plate → pre-oiling door → ato unit → strike with the hand open chock plate → work of opening the throttle with hand.If but behind the ato unit, forget when strikeing out chock plate with the hand, open the throttle motor because of the few engine misses that cause of air inlet this moment.For this reason, many manufacturers and knowledgeable people develop specially and develop, but not yet have so far comparatively ideal product to emerge.
Summary of the invention
The defects that exists when overcoming existing two strokes and four-stroke gasoline engine manual starting, the purpose of this utility model provide a kind of simple and reasonable, easy for operation, air door and open reliable air filter of engine and automatically open choke.
The utility model solves the problems of the technologies described above the technological scheme that adopts, it comprises the choke door-plate, the air filter seat, the chock plate control arm, the rotating shaft of choke door-plate is provided with the return torsion spring and is arranged on rotationally on the air filter seat, the choke door-plate is corresponding with the chock plate on the air filter seat, the chock plate control arm is fixedly connected with by the rotating shaft of screw with the choke door-plate, described air filter seat is provided with the double-action mechanism of automatically opening chock plate, this mechanism comprises spring groove and the chute that is arranged on the air filter seat, Returnning spring, the return plate, the return plate slidably arranges in the chute, Returnning spring is arranged in the spring groove and pushing tow return sheet reset, the return plate is provided with the first screens and the second screens, and the chock plate control arm is provided with the fixture block that matches with the first and second screens.
Described return plate is provided with the pulling buckle that matches with the open out device.
After adopting said structure, compared with prior art have the following advantages: during engine start, the manual-lock chock plate; When after the engine start during open out, the open out device drives the return plate and moves, and the first screens on the return plate is separated with the fixture block of chock plate control arm, and the choke door-plate is opened chock plate automatically under the elastic force effect of return torsion spring; When unclamping the open out device, the return plate resets under the elastic force effect of Returnning spring, the second screens on the return plate is combined with the fixture block of chock plate control arm, even the open out device again drives the return plate and moves, chock plate is in open mode and remains constant, guarantees to have abundant air and gasoline mixed combustion.Manual-lock chock plate when efficiently solving the user because of engine start, and forget with hand after starting and remove to open chock plate, air fuel ratio is seriously lacked of proper care during engine operation, causes motor flame-out when high speed operation, the problem that can cause motor to damage when serious.The reliability and stability of engine start have greatly been improved.
