Description
[technical field]
The invention relates to a kind of oil gas collecting device of use for general-purpose engines.
[background technique]
Science and technology is growing, environmental consciousness constantly promotes, make every environmental pollution be subjected to the attention of society, for example: water pollution, noise pollution and atmospheric pollution etc., all by society concern, relatively the government has also begun every pollution is taked the effective counter measure and required standard, just as the pollution of air etc., the toxic gas that fuel oil is distributed in the fuel tank, government has begun to pay attention to, the oil gas that requires to be evaporated in the fuel tank does not intersperse among in the atmosphere, in order to avoid cause atmospheric pollution.
Yet, well-known at present as: the power source body of mowing machine, generator, suction engine and sprinkler etc., the above-mentioned said air-polluting facts that causes all can take place, and is to be generally called power source bodies such as above-mentioned this mowing machine, generator, suction engine and sprinkler with one " the general machine of using " in following specification of the present invention.
See also shown in Figure 1, this is general to be to have an engine 11 with machine 10, these engine 11 tops are to be provided with a fuel tank 12, be to be provided with an oil filler 13 on this fuel tank 12, make that a fuel oil can be in this oil filler 13 places import fuel tank 12, and establish a lid 14 at these oil filler 13 loam cakes and overflow from these oil filler 13 places to prevent oil body.
In addition, one side of this engine 11 is to be provided with an air-strainer 15, after making that these fuel tank 12 interior fuel oils can be mixed into oil gas with the air that this air-strainer 15 is imported in a Carburetor 16, enter combustion explosion in this engine 11, and then the bent axles 18 that drive in the crankcase 17 rotate, and finish that this is general with the due power functions of machine 10 itself.
But, known this general device with machine 10, as shown in Figure 1, in order to make the fuel oil in this fuel tank 12 can flow in the Carburetor 16 smoothly, so on this fuel tank 12, be provided with a ventilating hole 19, making the fuel oils in this fuel tank 12 flowed into smoothly in this Carburetor 16 by the atmospheric pressure effect, and the air mixing olefiant gas that is imported with this air-strainer 15; So, cause the oil gas of evaporation in this fuel tank 12 to intersperse among in the outside atmosphere also relatively, and then cause atmospheric pollution directly leading directly to by this ventilating hole 19.
[summary of the invention]
Because the deep introduction of above-mentioned background technology, we are not difficult to learn the known general machine of using, in order to make the fuel oil in its fuel tank flow into smoothly in the Carburetor, so on this fuel tank, can be provided with a ventilating hole, yet the setting of this ventilating hole, cause the oil gas of evaporation in this fuel tank directly to intersperse among in the outside atmosphere also relatively, and then cause the air-polluting situation to take place by this ventilating hole is straight-through; Therefore, constantly promote based on environmental consciousness, and in order to solve the above problems, purpose of the present invention, be that a kind of oil gas collecting device of use for general-purpose engines is being provided, can avoid the interior oil gas that is evaporated of this fuel tank directly to intersperse among and cause atmospheric pollution in the outside atmosphere, can reach the effect of this oil gas collection device of convenient for maintaining again.
The oil gas collecting device of a kind of use for general-purpose engines of the present invention, comprise: one is arranged on this general fuel tank of using the engine top of machine, this fuel tank is provided with an oil filler and an oil gas mouth, and a side of this engine is respectively equipped with an air-strainer and a Carburetor, it is characterized in that: also comprise:
One is arranged on the oil gas collection device of this fuel tank top, and an end of this oil gas collection device is respectively equipped with the oil droplet exhaust port that a ventilating hole and is lower than this ventilating hole, and this oil droplet exhaust port is near this fuel tank.
The oil gas collecting device of described use for general-purpose engines is characterized in that: the angle that is provided with of this oil gas collection device is to be a downtilt angles with this fuel tank upper horizontal face, more is close to this fuel tank top with the oil droplet exhaust port that makes this oil gas collection device.
The oil gas collecting device of described use for general-purpose engines is characterized in that: this fuel tank upper horizontal face is provided with a guiding gutter.
The oil gas collecting device of described use for general-purpose engines is characterized in that: the oil droplet exhaust port of this oil gas collection device is towards this guiding gutter direction setting.
The present invention will have following advantage:
1, because this oil gas collection device is arranged on this fuel tank top, make the oil gas that fuel tank evaporated to be absorbed fully by this oil gas collection device, and this fuel tank is when filling it up with oil, can be too not low because of the setting of this oil gas collection device, and it is full in this oil gas collection device to cause fuel oil to ooze, cause this oil gas collection device to lose the effect of original oil gas collection, further be lower than this ventilating hole because of the oil droplet exhaust port, when the oil gas saturation of oil gas collection device absorption is saturated, oil droplet can more successfully be discharged, cause engine to start or flame-out phenomenon generation and can avoid this oil gas collection device to stop up.
2, because this oil gas collection device is arranged on this fuel tank top, make this oil gas collection device can reach the purpose of convenient for maintaining.
3, in this oil gas collection device excessive oil gas because of accumulating saturated formed oil droplet, then can successfully be expelled to a guiding gutter place (being non-hot zone) on this fuel tank from oil droplet exhaust port on it, and unlikely random everywhere dripping, can effectively do one and separate, take place to avoid the dangerous facts with a hot zone (being outlet pipe and the zone of covering the heat lid).
4, because the angle that is provided with of this oil gas collection device is to be a downtilt angles with this fuel tank upper horizontal face, by this, the oil droplet that its oil droplet exhaust port is flowed out is more successfully discharged.
For understanding being arranged further and understands to technological means of the present invention and operation, cooperate graphicly now for embodiment, be described in detail as follows:
