[0002] During the process of machining and cutting parts, CNC lathes will generate a lot of heat due to the strong friction between metals. When the cutting fluid absorbs a lot of heat, most of it will be recovered and utilized, but a part of it will evaporate and become emulsion, oil mist and oil smoke.

[0003] A Chinese patent discloses a novel oil mist collector with the publication number CN209333399U, comprising a main collecting box and a HEPA filter, wherein the main collecting box is provided with an air suction port and an air outlet, the air suction port is arranged at the center position of the end of the main collecting box, the air outlet is opened at the upper position of the tail of the main collecting box, the HEPA filter is fixedly installed above the main collecting box and is connected with the inner cavity of the main collecting box through the air outlet, and a coarse-effect HEPA filter, a foam layer, an oil-passing net, an impeller bin and a gas separation bin are arranged in sequence inside the main collecting box from the air suction port to the air outlet, the foam layer is 50PPI foam, the novel oil mist collector has a simple structure and a reasonable design, can fully filter and collect the oil mist, and can inspect and repair the oil mist collector through an inspection plate arranged at the tail end of the main collecting box, thereby reducing the maintenance cost, and utilizing the composite high-efficiency HEPA filter to extend the service life of the oil mist collector, thereby reducing the use cost while achieving high-efficiency filtration.

[0004] However, there are still the following disadvantages: the device is equipped with a coarse HEPA filter, a foam layer and an oil filter to filter the oil mist, but the filter device inside the device is not easy to remove, and it is not easy to replace and clean the filter components inside the device. Therefore, we propose an oil mist collector for machine tools to solve this problem. Utility Model Content
