As shown in fig. 9-12, the exhaust gas box 5 is fixedly installed inside the air filter housing 3, specifically in the exhaust cavity 32 of the exhaust gas box 5, and the air inlet of the exhaust gas box 5 is connected with the air outlet pipe of the crankcase. The top of the exhaust gas box 5 is provided with a cover plate 64, which cover plate 64 is used for sealing the exhaust gas box 5, and an outlet is formed in the cover plate 64, and an exhaust gas pipe 7 is mounted at the outlet, preferably, as shown in fig. 12, the exhaust gas pipe 7 is bent in the direction of the outlet pipe 2. The exhaust gas box 5 is provided with a separation assembly 6, and the separation assembly 6 is used for separating engine oil particles in the exhaust gas. The separation assembly 6 comprises a first baffle 61, a second baffle 62, and a cylindrical plate 63, the first baffle 61 and the second baffle 62 are each provided in plurality and the first baffle 61 and the second baffle 62 are alternately arranged so that an exhaust gas passage is formed in the exhaust gas tank 5, the cylindrical plate 63 is connected to the first baffle 61 and the second baffle 62, the cylindrical plate 63 is connected to the first baffle 61, and an inner wall of the cylindrical plate 63 forms an accommodation space. The first baffle 61 and the second baffle 62 are both in contact with the inner wall of the exhaust gas tank 5, the first baffle 61 and the cover plate 64 are in contact, and the second baffle 62 and the cover plate 64 have a gap so that the exhaust gas passes through. Crankcase waste gas lets in earlier in the waste gas case 5, because the setting of first baffle 61 and second baffle 62 forms spiral passageway in the waste gas incasement for waste gas will be spiral form upward flow in the waste gas case, and then receive centrifugal force effect, and waste gas takes place the striking with first baffle and second baffle in upward flow in-process, cause turbulent state, under centrifugal force and collision impact's combined action, engine oil granule in the waste gas will fully separate with gas, gas is discharged in the exhaust chamber through the waste gas pipe 7 on the apron, engine oil granule then adheres to on first baffle and second baffle and waste gas incasement wall, reflux to the waste gas case after the increase gathering of volume. Because the crankcase waste gas is discharged into the air outlet cavity after the engine oil is separated, the air filter element cannot be adhered to the engine oil, and the filter material on the filter element is only dust, so that the condition that the filter material is adhered to the filter paper and cannot be cleaned can not occur; and when the vehicle runs on a slope or jolts, the driving assembly drives the air filter element to rotate, so that dust on the filter paper can be shaken off when the scraping plate and the filter paper scrape, the filtering efficiency of the filter element is improved, the air inlet to the engine is completely filtered, the air entering the engine after filtering is ensured to have no filtered matters such as dust, the damage probability of the engine is reduced, and the maintenance cost is reduced. Meanwhile, in the mode, the service life of the air filter element is effectively prolonged, frequent replacement of the air filter element is not needed, and consumable materials are reduced; the air filter element can rotate, so that the air filter element can be cleaned in an omnibearing manner, and the cleaning effect and the filtering effect are further improved; and the filtered material is collected in the waste box through the opening and cannot be sucked into the filter element again. Meanwhile, the air filter element is driven to rotate by ascending and descending slopes or jolting of the vehicle, independent power is not required to be set, and energy consumption and cost are effectively reduced.
Secondly, the waste gas cavity is relatively airtight and is not directly communicated with the external environment, and waste gas of the crankcase enters the waste gas box and is hardly diffused into the external environment, so that environmental pollution is not caused, and double-cavity filtering is realized; and the engine oil in the waste gas can be recycled, so that the problem of carbon deposition of the engine caused by engine oil particles in the waste gas is solved, and the consumption of the engine oil can be reduced. Because the air outlet cavity is arranged between the air filter element and the air outlet pipe, the air volume between the throttle valve body and the air filter element of the engine is greatly increased by the air outlet cavity, a buffer area is formed, the stability of an air inlet system of the engine is greatly improved, noise and vibration are reduced, and the air outlet cavity is particularly obvious under the condition of rapid acceleration.
As shown in fig. 5 to 8, the driving assembly includes a swing member 91, a fixing base 92, and a notch 93, and the swing member 91 is similar to a fan-shaped structure and swings when the vehicle is on a downhill or sudden braking.

The notch 93 is the arc fluting of seting up on the end cover 81 outer wall, and the swinging member 91 lower extreme penetrates in this notch 93, and then contacts with external member 82, and when the swinging member 91 takes place the swing around the connecting piece, the swinging member 91 lower part just can drive the external member and take place to rotate, and the external member then drives the air filter and takes place to rotate. Preferably, the lower end of the swinging member 91 is provided with a second flexible layer 912, the second flexible layer 912 being rubber, increasing the friction between the swinging member and the sleeve.
As shown in fig. 5 and 8, the upper end of the swinging member 91 is provided with a through hole 911, the screw portion of the connecting member 94 is inserted into the through hole 911, and the diameter of the through hole 911 is larger than that of the screw of the connecting member 94, so that the swinging member can float up and down to a certain extent relative to the connecting member, and the air filter element can not rotate and revolve within the swinging range of the swinging member, but can rotate to a certain extent, and the air filter element is ensured to be cleaned comprehensively. Preferably, the connecting member 94 is sleeved with the first flexible layer 941 supported by rubber, so that the swinging member 91 cannot generate a sound due to impact in the process of floating relative to the connecting member 94, and the abrasion of the swinging member and the connecting member is reduced.
As shown in fig. 5 and 8, a sliding rail 913 is disposed at the lower portion of the swinging member 91, a counterweight 914 is disposed in the sliding rail 913, and the height of the sliding rail 913 is higher than that of the counterweight 914, so that the counterweight can slide smoothly in the sliding rail. When the acting force applied to the swinging member is smaller, the balancing weight 914 will move first, so that an acceleration is given to the swinging member to drive the swinging member to swing, and the acting force of the vehicle is more fully utilized to clean the air filter element. Preferably, the two ends of the sliding rail 914 are respectively provided with a groove 916, and the height of the grooves 916 is smaller than that of the balancing weight 914, so that when the balancing weight 914 slides to the end position of the sliding rail, a part of air is extruded in the grooves 916, the balancing weight 914 can be buffered, impact sounds are avoided, a reverse acting force can be applied to the swinging member, and the swinging member can be driven to swing better. In order to prevent dust from entering the sliding rail, the side wall of the second flexible layer 912 extends upwards to form a flexible sleeve, and the flexible sleeve is directly coated outside the swinging member 91.
As shown in fig. 9, the scraper 83 is inclined from bottom to top, and an open slot 831 is formed at the lower end of the scraper 83, so that even if the waste is accumulated on the upper surface of the scraper, the waste can slide down along the inclination of the scraper, fall into the waste box through the open slot, and cannot be carried to the air filter element again.
