Description
Technical field
The invention relates to a kind of automatic throttle device of petrol engine, particularly a kind of self closing door switch gear that is arranged on the gasoline engine air filter.
Background technique
For the season of cold or under cold machine state starting up gasoline engine smoothly, denseer blended fuel oil gas need to be provided, improve the starting performance of petrol engine, just at Carburetor and air filter various types of enrichment-systems have been installed, at present, gasoline feeder employed enrichment-system in market mainly contains following several.
1. Carburetor electricity enriching enrichment-system: Carburetor electricity enrichment-system mainly be by other increase by one road binders road when the starting to the more gasoline of petrol engine to reach the effect of enriching, this device usage comparison on foot plate bicycle is extensive, performance is relatively reliable, but electric enrichment-system needs stable 12V Power supply slowly oil circuit to be shut within a certain period of time, this will directly cause the oil consumption of petrol engine to increase, and when circuit breaks down, electricity enrichment-system job insecurity, the oil consumption height can appear in petrol engine, over-emitting black exhaust, without high speed, infringement to petrol engine is serious, and be difficult to for the moment be found by the Consumer, cause Consumer's immediate interest to incur loss, do not meet the energy-saving and emission-reduction that International Environmental Protection tissue and country propose, the requirement of low-carbon environment-friendly.
2. the manual enrichment-system of Carburetor is similar with electric enrichment-system, be by other increase by one road binders road when starting to the more gasoline of petrol engine to reach the effect of enriching, but this device is not then to be to reach the purpose of enriching by the manual toggle switch of operator by 12V power supply control, this device is grasped and is not easy, inconvenient operation is also unstable, is unfavorable for the use of vehicle.
3. Carburetor and air filter manual air door device: Carburetor and air filter manual air door device, refer in the situation of certain amount of gasoline, by shutoff normal air mouth, to reduce the inlet of air, so that petrol engine can obtain denseer proportions of ingredients, motor mounting point reason owing to car load, Carburetor and air filter manual air door device are in more hidden position, if accomplish the switch of air door, operate too loaded down with trivial details unavoidably, if control air door a switch install on the handgrip, can make like this vehicle frame too complicated, cost can increase, and the control switch on the handle is also too much, is unfavorable for easily travelling.
For the problems referred to above, many scientific research institutions, manufacturer and knowledgeable people have carried out R and D, but not yet have so far more satisfactory mode to emerge; Therefore, developing a kind of simple and compact for structure, safe and practical automatic throttle device is extremely urgent problem.
Summary of the invention
For overcome that existing throttle setting exists defects, the purpose of the invention provide a kind of simple and reasonable, starting is reliable and stable, volume is little, cost is low, need not manually operated gasoline engine air filter automatic throttle device.
The invention solves the problems of the technologies described above the technological scheme that adopts; it comprises air filter body and self closing door controlling mechanism; the air filter body is provided with the carburetor air mouth that is connected with Carburetor; described self closing door controlling mechanism comprises chock plate; pull bar; electromagnet; reset tension spring; chock plate is hinged on the air filter body rotationally; electromagnet is fixed on the air filter body; one end of chock plate is corresponding with the carburetor air mouth; one end of the other end of chock plate and pull bar is hinged; the other end of pull bar matches with electromagnet; reset tension spring is arranged between air filter body and the chock plate, and reset tension spring is used for controlling the normal return of chock plate.
Described pull bar is arranged in the electromagnet, and pull bar can move back and forth in electromagnet under magnetic force and spring-force driven dual.
Described air filter body is provided with positive stop.
After adopting said structure, following advantage and effect are compared with prior art arranged: when electromagnet is switched on, electromagnet holds pull bar, this moment, the chock plate afterbody was drop-down by pull bar, chock plate produces rotation after overcoming the elastic force of reset tension spring, the carburetor air mouth that head moves upward and blocks air filter, the reset tension spring that chock plate is connected with air filter opens, and air door is closed.When electromagnet cut off the power supply, electromagnet disappeared to the suction of pull bar, and chock plate is rotary reset under the pulling force of reset tension spring, until stop operating after leaning against positive stop, air door reopens.The invention can be controlled under the enriching state in good time, need not to switch on always, has that starting process is simple and convenient, starting is reliable and stable, safe and practical, volume is little, low cost and other advantages.

1 electromagnet wherein, 2 pull bars, 3 connecting pins, 4 air filter bodies, 5 carburetor air mouths, 6 chock plates, 7 positive stops, 8 reset tension springs.
Embodiment
Illustrated in figures 1 and 2; specific embodiments for the utility model gasoline engine air filter automatic throttle device; it comprises air filter body 4 and self closing door controlling mechanism; air filter body 4 is provided with the carburetor air mouth 5 that is connected with Carburetor; described self closing door controlling mechanism comprises chock plate 6; pull bar 2; electromagnet 1; reset tension spring 8; chock plate 6 is hinged on the air filter body 4 rotationally; electromagnet 1 is fixed on the air filter body 4; one end of chock plate 6 is corresponding with carburetor air mouth 5; the other end of chock plate 6 is hinged with an end of pull bar 2 by connecting pin 3; the other end of pull bar 2 and electromagnet 1 match to merge and are arranged in the electromagnet 1; pull bar 2 can move back and forth in electromagnet 1 under magnetic force and the spring-force driven dual; reset tension spring 8 is arranged between air filter body 4 and the chock plate 6, and reset tension spring 8 is used for controlling chock plate 6 normal returns.Described air filter body 4 is provided with positive stop 7.
The automatic throttle device working procedure of the invention is as follows: before the startup, as shown in Figure 1, chock plate 6 leans against on the positive stop 7 under the elastic force effect of reset tension spring 8, and the head of chock plate 6 separates with the carburetor air mouth 5 of air filter body 4, and air door is in open mode; When pressing the enable switch starting, by detector control electromagnet 1 "on" position, electromagnet 1 produces magnetic force and holds iron pull bar 2 after the energising, pull bar 2 drives chock plate 6 rotations and blocks the carburetor air mouth 5 of air filter body 4 behind the elastic force that overcomes reset tension spring 8, this moment the air door closed state, as shown in Figure 2, provide denseer blended fuel oil gas for petrol engine.After gasoline engine starting, disconnect electromagnet 1 by the detector detection and by controller, electromagnet 1 dead electricity magnetic force disappearance releasing lever 2, chock plate 6 resets under the elastic force effect that overcomes reset tension spring 8 and leans against on the positive stop 7, the head of chock plate 6 separates with the carburetor air mouth 5 of air filter body 4, and air door reopens.
The above; just an embodiment of the invention is not that any pro forma restriction is made in the invention, is not breaking away from the technological scheme basis of the invention; the simple modification of having done, equivalent variations or modification all fall into the protection domain of the invention.
