Abstract

The utility model discloses an air filter, comprising a shell cover, a shell body, an inlet pipe, an outlet and a filter element. The filter element is arranged in the shell body. The entrance end of the inlet pipe is provided with a filter device which is composed of a piece of sponge, a rack and an air inlet cover. The rack is provided with a latticed interlayer. The sponge is arranged in the interlayer. The rack is fixed on a pedestal. The shell can also be connected outside with an air transformation box. The utility model is designed with the double-filter structure; the air purified twice is transferred into an engine burning room through a carburetor; therefore the service life of the filter element is prolonged, the maintenance to the filter element is thereby reduced, and the use of the filter element becomes easier and more convenient. Meanwhile the problem of the recycle of the burning mixture remained in a bent axle box is solved in the utility model by the air transformation box, and the remained air can be further utilized, so that the discharge of the harmful air, such as CO, is further reduced and the efficiency of the engine is improved.

Description

The empty filter of dual filtering type

Technical field

The utility model provides a kind of empty filter, especially a kind of empty filter that is used for motorcycle engine.

Background technique

Air cleaner for motorcycle generally is made up of cap, housing, suction tude, steam outlet pipe, filter core, and filter core is built in the housing, i.e. the entry end of steam outlet pipe.The air that is entered by suction tude purifies through filter core, removes the silt dust, enters outer pipe again.Above-mentioned cleaned air passes enters engine chamber through the Carburetor of motor.The deficiency of this structure is that ambient air advances to connect to enter in the housing of sky filter, and only by once filtering, the working life that influences filter core is short, increases the user cost height, and safeguards inconvenient.Simultaneously because of in the Carburetor oil duct that directly links to each other with empty filter, the air flue than multiple component, as main jet, idle metering jet, primary air metering-orifice, idle metering jet or the like the very little hole of internal diameter is arranged all, if airborne contaminant filter is incomplete, tend to these apertures are stopped up, cause the Carburetor deficient airway, the Carburetor fuel feeding is obstructed, causes the engine performance fault.In addition, during engine operation, the upper and lower motion of piston has a spot of burning mixture in crankcase, and motor and the empty filter that joins with it all do not have special gas sampling device, often with the directly outwards discharging of these gases, causes waste, befouling environment.Along with the progress of society, people more and more pay attention to oil consumption, noise and toxic emission, therefore how above-mentioned mixed gas are used, and reduce oil consumption, reduce and pollute, also be a problem demanding prompt solution.

The model utility content

The purpose of this utility model is to provide a kind of empty filter that is provided with the secondary filter structure, improve the working life of filter core, and reduce maintenance, offer the more clean air of engine chamber simultaneously filter core, improve the effect and the life-span of motor, reduce toxic emission.

Another purpose of the present utility model is, on the basis of said structure, sets up one and changes device of air, and the mixed gas with in the crankcase that is used to reclaim motor further reaches fuel-economizing, reduces the effect of toxic emission.

For achieving the above object, the utility model provides a kind of empty filter, is made up of cap, housing, suction tude, steam outlet pipe and filter core, and filter core is arranged in the housing, and the entry end of suction tude is provided with filtrating equipment; Described filtrating equipment is made up of foam body, rack and air-inlet cover, and rack is provided with latticed interlayer, and foam body is built in the interlayer, and rack is fixed on the base.

Above-mentioned rack is made up of the fixing frame of two U types, passes through the grab engagement connection respectively on base, forms interlayer

Above-mentioned housing also is circumscribed with an air circulating box, and this air circulating box is an air storing cavity, and air circulating box is provided with a waste gas inlet, and the air outlet communicates with the inlet of steam outlet pipe.

Above-mentioned air circulating box is a triangle.

The utility model adopts the double filtration structure, and after extraneous air filtered for the first time by foam body, the air of cleaning entered the sky filter, and through the filtration once more of filter core, cleaned air passes enters engine chamber through Carburetor.Once to pass through the filter core filtered air cleaner for air ratio by secondary filter like this, thereby make sky filter, Carburetor, motor be in the optimum state for a long time, improved the working life of empty filter and entire engine.Simultaneously, empty filter the inside is cleaner than the empty filter that does not have air intake filter, has reduced the maintenance to filter core the working life of having improved filter core, uses more economically, conveniently.Simultaneously, the utility model has also solved the problem of the recovery of burning mixture residual in the crankcase, and is used.When above-mentioned empty filter is connected with motorcycle engine, air circulating box crankcase direct and motor joins, mixed gas in the crankcase is flowed into steam outlet pipe through waste gas inlet through air circulating box, enter engine chamber through Carburetor, reduce discharge of harmful gases such as car load oil consumption and CO, improved the effect of motor further.

Embodiment

As shown in Figure 1, 2, the utility model provides a kind of empty filter, and this sky filter is the empty filter of environment protection type, mainly is equipped with the GY6 motor, assembles the scooter type motorcycle of various models, and the utility model is not limited only to the empty filter of this model.Above-mentioned empty filter is made up of housing 1, suction tude 2, steam outlet pipe 3 and filter core 4.

Housing 1 is provided with cap 7, and filter core 4 is arranged in the housing 1, and the entry end of suction tude 2 is provided with filtrating equipment 5; Described filtrating equipment 5 is made up of foam body 51, rack and air-inlet cover 52, rack comprises two U type fixing frames, be inner fixed stand 53 and external fixing rack 54, and base 55, inner fixed stand 53 is built within the external fixing rack 54, its each surface all is designed to latticed, during assembling, its net muscle 531,541 is corresponding one by one, form interlayer between the surface of inside and
