Description

Technical Field

[0002] Oil fume purification device refers to the treatment device of oil fume exhaust gas, which is mainly used for the purification and treatment of oil fume discharged from low altitude in the kitchen; it is used in hotels, restaurants, taverns, schools, government agencies, factories and other places;

[0003] Publication number CN220567326U discloses an environmentally friendly oil fume separation and purification range hood, which starts the motor and drives the exhaust fan to rotate. The rotation of the exhaust fan will generate suction to discharge the inhaled gas into the exhaust port, and the generated oil fume will be absorbed. Due to the difference between oil and smoke in the oil fume, the smoke will pass through the smoke filter without any obstacles, but the oil carried by the smoke will be filtered out. It can be seen that it only filters the oil through the filter, and the oil removal effect of this device is poor. For this reason, we propose an oil fume purification device. Utility Model Content
