The bottom of the air inlet box 7 is provided with an opening 13, the interior of the air inlet box 7 is communicated with the interior of the purification box 6, and a secondary filter screen 9 is arranged between the air inlet box 7 and the purification box 6. An air outlet 14 is arranged on the air outlet box 8, and the air outlet box 8 is communicated with the purifying box 6.
The top of the fume collecting hood 1 is hermetically connected with the bottom of the main box body. The air outlet of the fume collecting hood 1 is communicated with the bottom opening 13 of the air inlet box 7.
The working principle of the range hood is as follows: after the range hood is powered on and opened, the exhaust fan begins to exhaust air in the air outlet box 8, so that negative pressure is formed in the range hood, and the external smoke is sucked from the smoke collecting hood 1 due to the internal and external air pressure difference of the range hood. The flue gas firstly passes through the air deflector 2, the air deflector 2 enables the flue gas to enter the smoke collecting hood 1 from gaps at the edge of the flue gas, the flue gas can pass through the edge of the primary filter screen 3 when flowing through the primary filter screen 3, and can spread to the middle of the primary filter screen 3 and pass through the middle of the primary filter screen 3, so that the flue gas can be uniformly contacted with all parts of the primary filter screen 3 in the process of flowing through the primary filter screen 3 instead of flowing through a certain part of the primary filter screen 3 in a centralized manner, the primary filter screen 3 can have a better filtering effect on the flue gas, the primary filter screen 3 can intercept larger impurities in the air, and can also play a role of primary filtering the flue gas, and can intercept part of oil in the flue gas. The flue gas passes through oil slinger 4 afterwards, and oil slinger 4 is rotatory fast, with the oil smoke and the air separation of flue gas effectively, realizes leading dynamic interception function promptly, and the oil that separates out converges into the food tray, and after the lampblack absorber used a period, can with the oil discharge in the food tray.
The flue gas flows through the oil thrower 4 and then flows into the air inlet box 7, and then flows into the purifying box 6 through the air inlet box 7, and in the process, the flue gas flows through the secondary filter screen 9, the secondary filter screen 9 in the embodiment is of a screen-shaped structure, most particles in the flue gas are adsorbed and filtered due to the collision of inertia effect and the secondary filter screen 9, and the concentration of oil mist particles flowing out of the secondary filter screen 9 is greatly reduced. Because the secondary filter screen 9 is of a screen-shaped structure, the air inlet box 7 and the secondary filter screen 9 are matched to play a role in pressure equalization and flow stabilization, so that the flue gas can uniformly and smoothly flow into the purification box 6. The flue gas firstly passes through the primary ultraviolet lamp group 10, ozone is generated on the surface of a lamp tube of the primary ultraviolet lamp group 10 and is combined with peculiar smell molecules, so that the primary peculiar smell removing purpose is achieved, the flue gas uniformly and smoothly flows through the high-voltage electrostatic field, so that oil stain particles in the flue gas can be more fully decomposed and adsorbed by the high-voltage electrostatic field, and a better purifying effect is achieved. After passing through the high-voltage electrostatic field, most of oil stains in the flue gas are purified, and the air flowing out of the high-voltage electrostatic field reaches the discharge standard.
