The radial cross-section of the first semicircular tube and the second semicircular tube of the patent technology is semicircular or semi-elliptical, and the ventilator elbow is split. The ventilator elbow is formed by connecting the first semicircular tube and the second semicircular tube. The first semicircular tube and the second semicircular tube are processed by stamping to avoid wrinkles or depressions on the surface of the first semicircular tube and the second semicircular tube. At the same time, the requirements of the stamping process on the bending radius The first connection port is connected with the second connection port to form a ventilation elbow, and a ventilation elbow is formed inside the ventilation elbow. The ventilation elbow has a smooth transition as a whole, and the air flow is smooth. However, since the connection between the frame surface and the ventilation pipe is a smooth arc surface, it is very difficult to position the ventilation pipe during welding, and the position of the ventilation pipe may be offset during welding, which affects the normal connection between the ventilation pipe and other structures. Therefore, the inventor provides a motorcycle frame ventilation pipe to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0021] like Figure 1 , 2 As shown, a motorcycle frame snorkel comprises a connecting frame 10, a connecting groove 11 is provided on the front of the connecting frame 10, a fitting ring 12 is fixedly connected to the outer side of the connecting groove 11, and the rear side of the fitting ring 12 is arc-shaped and fits the arc-shaped surface of the connecting frame 10. A snorkel body 30 is installed on the front of the connecting frame 10, and a connecting pipe 20 is installed between the connecting frame 10 and the snorkel body 30 for easy docking.

[0022] refer to Figure 2 The left side of the connecting tube 20 is fixedly connected with a connecting portion 21, and the connecting portion 21 is an arc-shaped design that fits the surface of the connecting frame 10. The connecting portion 21 is adapted to the internal shape of the fitting ring 12. When in use, the connecting portion 21 is inserted into the fitting ring 12, and the connecting portion 21 fits the surface of the fitting ring 12 and the rear side of the connecting portion 21 is against the outer surface of the connecting groove 11, and then the connection between the connecting portion 21 and the fitting ring 12 is welded, so as to achieve the fixation of the connecting tube 20 and the connecting frame 10; inserting the connecting portion 21 into the fitting ring 12 can prevent the trouble of positioning the connecting portion 21 during welding, and at the same time prevent the connecting portion 21 from sliding or rotating during welding.

[0023] refer to Figure 2 , 3The right side of the connecting pipe 20 is fixedly connected with a first flange 22, and the left side of the ventilating pipe body 30 is fixedly connected with a second flange 31. When in use, the first flange 22 and the second flange 31 are welded to achieve the effect of fixing the ventilating pipe body 30 to the connecting frame 10; at the same time, since the right side of the connecting pipe 20 and the left side of the ventilating pipe body 30 have flat surfaces, the positioning and welding of the two flanges are facilitated.

[0024] When the breather pipe body 30 is in use, the gasoline inside the motorcycle may not react fully and combine with dust in the air to adhere to the inner surface of the breather pipe body 30, affecting the normal exhaust of the breather pipe body 30. Therefore, it is necessary to clean the dirt inside the breather pipe body 30.

[0025] refer to Figure 4 , 5 The same cleaning mechanism 40 is installed on the front of the first flange 22 and the rear end of the vent body 30. When the first flange 22 is connected to the second flange 31, the cleaning mechanism 40 on the first flange 22 can effectively clean the dirt on the left end of the vent body 30. The cleaning mechanism 40 includes a fixed block 401 fixedly connected to the left and right sides of the first flange 22, and the upper and lower sides of the front of the fixed block 401 are provided with a flip groove 402.

[0027] When the motorcycle is started, gas flows toward the ventilator body 30, and the airflow slightly pushes the two flaps 404. When the motorcycle is accelerated to increase the gas flow rate, the impact force of the airflow causes the two flaps 404 to flip toward each other, and at the same time drives the support spring 407 to compress. When the airflow weakens, the suppression effect of the support spring 407 weakens, driving the two flaps 404 to flip toward each other, so that the two knocking blocks 405 knock onto the left end of the ventilator body 30 and the inner side of the rear end of the ventilator body 30, knocking off the dust crust inside the ventilator body 30, and then discharging it from the ventilator body 30 with the gas.

[0028] The working principle of the utility model is: inserting the connecting part 21 into the fitting ring 12, the connecting part 21 fits with the surface of the fitting ring 12 and the rear side of the connecting part 21 abuts against the outer surface of the connecting groove 11, and then welding the connection between the connecting part 21 and the fitting ring 12, so as to achieve the fixation of the connecting pipe 20 and the connecting frame 10; inserting the connecting part 21 into the fitting ring 12 can prevent the trouble of positioning the connecting part 21 during welding, and at the same time prevent the connection part 21 from sliding or rotating during welding, and then welding the first flange 22 and the second flange 31, so as to achieve the effect of fixing the ventilating pipe body 30 and the connecting frame 10; at the same time, since the surfaces of the right side of the connecting pipe 20 and the left side of the ventilating pipe body 30 are flat, it is convenient to position and weld the two flanges.
