Discharging the concentration of carbon monoxide in waste gas to reduce motorcycle, air intaking for motor cycle system is generally adopted secondary air supplementing valve method.Waste gas owing to discharging has certain temperature, injects fresh air toward the exhaust end of electromotor so that the carbon monoxide in waste gas is oxidized, thus reducing carbon monoxide in waste gas while waste gas discharged by motorcycle.
Existing air intaking for motor cycle system, including air filter, secondary air supplementing valve air inlet pipe, secondary air supplementing valve, escape pipe, secondary air supplementing valve escape pipe and check valve breather, air is after air filter filters, secondary air supplementing valve is entered through secondary air supplementing valve air inlet pipe, secondary air supplementing valve is connected to escape pipe and secondary air supplementing valve escape pipe, an air part for secondary air supplementing valve flows to the inlet end of electromotor through escape pipe, another part flows to check valve breather through secondary air supplementing valve escape pipe, the exhaust end of rear flow direction engine.
Existing motorcycle causes motorcycle idle speed noise big due to the vibration such as electromotor, vehicle body.In order to solve the noise problem of motorcycle, applicant proposed a kind of low noise air intaking for motor cycle system, reduce the idling noise of motorcycle, but while realizing low noise air intaking for motor cycle system, applicant also needs to consider how to design a kind of check valve ventilation device so that the exhaust end inflow noise of electromotor reduces.
Utility model content
For above shortcomings in prior art, this utility model patent provides the check valve ventilation device of a kind of air intaking for motor cycle system, for reducing the exhaust end inflow noise of electromotor.
For solving above-mentioned technical problem, it is achieved utility model purpose, the technical solution adopted in the utility model is as follows:
The check valve ventilation device of air intaking for motor cycle system, including secondary air supplementing valve, secondary air supplementing valve escape pipe, check valve breather and electromotor；The outlet side of secondary air supplementing valve is by being sequentially connected with secondary air supplementing valve escape pipe and check valve breather, it is connected to the exhaust end of electromotor, wherein, secondary air supplementing valve escape pipe and check valve breather connect and are collectively forming the venting channels of exhaust end from the outlet side of secondary air supplementing valve to electromotor；The bending tube of described secondary air supplementing valve escape pipe generally L-type, including the second bending segment that the first bending segment of length length and length are short, first bending segment end of secondary air supplementing valve escape pipe is connected with the outlet side of secondary air supplementing valve, and the second bending segment end is connected with check valve breather.
As the further optimization of such scheme, the inwall of described secondary air supplementing valve escape pipe is equipped with cotton.
As the further optimization of such scheme, described secondary air supplementing valve escape pipe is one-body molded.
Further optimization as such scheme, described check valve breather generally has the bending tube of L-type bending segment, the both ends of L-type bending segment extend along the same direction bending being perpendicular to L-type bending segment place plane respectively, forming two connecting portions, the both ends of check valve breather are connected on the second bending segment end of secondary air supplementing valve escape pipe and the exhaust end of electromotor.
Compared to prior art, this utility model has the advantage that
1, check valve ventilation device of the present utility model, secondary air supplementing valve escape pipe is bending tube, increasing the air inlet process of engine exhaust end, gas is turned and is made gas form harmonic wave in venting channels simultaneously, significantly reduces the inflow noise of engine exhaust end.
2, check valve ventilation device of the present utility model, namely cotton serves sound-absorbing effect, also enhances the intensity of secondary air supplementing valve escape pipe, it is to avoid deformation.
3, check valve ventilation device of the present utility model, check valve breather is three forming elbows, secondary air supplementing valve escape pipe is twice forming elbow, connection by the two pipe fitting, when the air of secondary air compensating enters electromotor from secondary air supplementing valve, continuously across five turnings, the effect of noise reduction need to be played better.
4, check valve ventilation device processing technology of the present utility model is simple, and efficiency of assembling is high.
Accompanying drawing explanation
Fig. 1 is the structure chart of the check valve ventilation device of this utility model embodiment.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment:
The check valve ventilation device of air intaking for motor cycle system, as it is shown in figure 1, include secondary air supplementing valve 4, secondary air supplementing valve escape pipe 5, check valve breather 6 and electromotor 7；The outlet side of secondary air supplementing valve 4 is by being sequentially connected with secondary air supplementing valve escape pipe 5 and check valve breather 6, it is connected to the exhaust end of electromotor 7, wherein, secondary air supplementing valve escape pipe 5 and check valve breather 6 connect and are collectively forming the venting channels from the outlet side of secondary air supplementing valve 4 to the exhaust end of electromotor 7；The bending tube of described secondary air supplementing valve escape pipe 5 generally L-type, including the second bending segment that the first bending segment of length length and length are short, first bending segment end of secondary air supplementing valve escape pipe 5 is connected with the outlet side of secondary air supplementing valve 4, and the second bending segment end is connected with check valve breather 6.Described secondary air supplementing valve escape pipe 5 is one-body molded.
