However, during the use of the device, it is inconvenient to make the gas act evenly on the oil-absorbing cotton, resulting in a large density of oil and gas locally received by some oil-absorbing cotton, thereby affecting the overall filtering effect of the device. Therefore, certain improvements are needed. Utility Model Content
