[0017] Figure 4 It is Figure 3 The enlarged view of A in the figure. DETAILED DESCRIPTION

[0018] Referring to Figures 1 to 4 An air filter 1 of the utility model, including left casing 11, filter core support 12 and right casing 13, left casing 11 and right casing 13 are spliced and form the internal chamber, and filter core support 12 is clamped between left casing 11 and right casing 13 and divides the internal chamber into filter front chamber and filter rear chamber, filter front chamber is communicated with outside atmosphere, and filter rear chamber is communicated with engine intake end.

[0019] Air filter 1 is arranged with oil collecting chamber 2, and oil collecting chamber 2 is equipped with oil inlet 21 and oil outlet 22, and oil inlet 21 and oil outlet 22 are arranged in the side wall of oil collecting chamber 2 and are located outside oil collecting chamber 2 and form the docking mouth 24 with the oil collecting pipe and the oil discharge pipe docking. Among them, the oil outlet 22 is arranged close to the bottom wall of the oil collecting chamber 2, and the oil outlet 22 is communicated with the oil guide groove 23 on the bottom wall of the oil collecting chamber 2, and the oil -water mixture in the oil collecting chamber 2 is guided to concentrate and is discharged from the oil outlet 22 and is discharged outside into the oil discharge pipe, so that the oil -water mixture in the oil collecting chamber 2 can be fully and quickly discharged. And the bottom of the oil inlet 21 is higher than the bottom wall of the oil collecting chamber 2, so that the probability of the oil -water mixture in the oil collecting chamber 2 flowing back to the functional component is greatly reduced.
