Referring to fig. 1 and 3, a range hood for efficiently purifying oil smoke comprises a smoke collecting hood 1 and a main box body, wherein an air deflector 2, a primary filter screen 3 and an oil thrower 4 are sequentially arranged in the smoke collecting hood 1 along the air suction direction, and a gap is formed between the edge of the air deflector 2 and the smoke collecting hood 1.

Referring to fig. 1 and 2, the main cabinet includes an air inlet box 7, a purification box 6 and an air outlet box 8 connected in sequence, the air inlet box 7 is used for guiding the smoke sucked into the range hood into the purification box 6, the air outlet box 8 is used for discharging the air flowing out from the purification box 6 out of the range hood, and an exhaust fan is installed in the air outlet box 8.

In this embodiment, a primary uv lamp group 10, a high voltage electrode 11, and a secondary uv lamp group 12 are sequentially installed in the purifying box 6 along the airflow direction. Wherein, the primary ultraviolet lamp group 10 is used for decomposing harmful smoke in the smoke, and strongly removing TVOC (Total Volatile Organic Compounds) odor, and plays a role in removing primary odor; the high-voltage electrode 11 is used for generating a high-voltage electrostatic field after being electrified, the high-voltage electrostatic field enables oil stain particles to have charges and enables partial oil stain particles and air to be ionized in the process that smoke gas flows through the high-voltage electrostatic field, the oil stain particles with the charges can be adsorbed on a negative pole plate of the high-voltage electrostatic field, and the ionized air can further oxidize and decompose the oil stain particles with the charges and the ionized oil stain particles, so that the oil smoke is purified by electrostatic adsorption and ionization decomposition; the secondary ultraviolet lamp set 12 is used for further decomposing harmful smoke in the smoke and further removing TVOC peculiar smell.

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. The air then flows through the secondary ultraviolet lamp set 12, and after the secondary odor removing effect of the secondary ultraviolet lamp set 12, the odor can be fully removed. The purified air is finally discharged from the air outlet 14 of the air outlet box 8.

In this embodiment, the primary ultraviolet lamp group 10 and the secondary ultraviolet lamp group 12 are both dual-frequency dual-band UV ultraviolet lamps, the dual-frequency dual-band UV ultraviolet lamps can emit ultraviolet rays in two bands, one band irradiates oil smoke through lamp tube glass and energizes peculiar smell molecules, so that the molecular structure of grease is changed, high molecular compounds are degraded into colorless and tasteless low molecular compounds, ozone can better combine with the peculiar smell molecules to react, and a better peculiar smell removing effect can be generated; the ultraviolet light of the two wave bands can generate a large amount of ozone on the surface of the lamp tube after penetrating through the lamp tube glass and contacting with oxygen, and the ozone is combined with the energized peculiar smell molecules to react and decompose the peculiar smell molecules, thereby achieving the aim of removing the peculiar smell. The ultraviolet lamp set is used for carrying out multiple groups of reactions, and the reaction process is repeated, so that the peculiar smell in the smoke is removed more uniformly and thoroughly. After multiple deodorization treatments, the deodorization efficiency can reach more than 98 percent.

Referring to fig. 1, in the present embodiment, a design of a plurality of oil throwers 4 is adopted, so that more efficient oil-smoke separation can be realized. And the surface of the oil thrower 4 is coated with a double-nano coating, so that the oil thrower 4 has self-cleaning capability, does not need cleaning, and avoids the oil thrower 4 from being blocked.
