The prefilter of this embodiment can perform two prefilters on the airflow. The arrows in FIG. 2 indicate the gas flow direction. In actual work, the gas first enters the first cylinder 10 from the gas inlet 11 and forms a swirling flow to hit the inner wall of the first cylinder 10, so that some water and large particles mixed in the gas are The dust is adsorbed on the inner wall of the first cylinder 10, and then the water and dust on the inner wall of the first cylinder 10 flow down to the first water storage tank due to the action of gravity, and finally discharged from the first outlet 13 to realize the first pre-filtering . Then, the airflow continues to move downward along the axial direction of the first cylinder body 10. Due to the high speed of the airflow, it will hit the bottom of the second water storage tank 31 during the downward movement. In the water storage tank 31, the air flow is returned to rise, and the water, dust and other impurities in the gas cannot rise with the air flow due to the action of gravity, so they stay in the second water storage tank 31, and then other impurities such as water and dust are discharged from the second outlet 32, Realize the second pre-filtering. In this way, the water and large particles of dust in the gas can be pre-filtered, and the pre-filtering effect can be greatly improved after two pre-filters.

In this embodiment, the structure of the swirl plate 12 + the first water storage tank + the first outlet 13 is adopted, and the baffle plate 14 is arranged to separate the channels of water and dust from the channels of air by taking advantage of the asymmetry of the weights of air, water and dust. , which improves the pre-filtering function of the air filter. In addition, as the water volume increases, the water pressure in the first drainage groove increases, thereby increasing the drainage speed. In order to achieve the effect of separating air, water and dust again, two spaces with different heights are set on the bottom cover 30 of the air filter, and the space far from the first cylinder 10 is set as a second water storage tank 31 for receiving water and The dust is then discharged through the second outlet 32 to achieve the effect of separation from the gas, further enhancing the pre-filtering effect.
