[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] Embodiment 1, the following will be combined with the drawings in the embodiment of the utility model to clearly and completely describe the technical scheme in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In this embodiment, refer to Figure 1The range hood shown includes a cover body 1 and a box body 2. The cover body 1 is arranged below the box body 2. A steel mesh 10 and a shield 5 are provided at the bottom of the cover body 1. The steel mesh 10 is connected to the shield 5. The box body 2 includes an oil fume purifier 8 and a metal filter 7. The oil fume enters the oil fume purifier 8 from the bottom of the cover body 1 through the metal filter 7 for purification.

[0023] The shield 5 is also a dynamic interceptor, and several of them are arranged at equal distances along the length direction of the cover body 1. The side walls of the box body 2 are provided with oil collecting grooves 6. When the blades on the dynamic interceptor are in a rotating state, larger oil smoke particles are captured and thrown into the oil collecting groove 6 by the principle of centrifugal force, thereby purifying about 75% of the oil smoke particles larger than 5 microns.

[0024] The bottom surface of the cover body 1 is provided with baffles 11 protruding inward horizontally on both sides to prevent the oil smoke from escaping. A plurality of air ducts 12 are opened on the side wall of the cover body 1 below the baffles 11, and the air ducts 12 are connected to the shield 5. At least one UV lamp tube 9 is provided at the outlet of the oil fume purifier 8. The oil fume purifier 8 is a high-low voltage electric field oil fume purifier 8. A control panel 3 is provided on the front of the cover body 1, and a plurality of buttons are provided on the control panel 3. A lighting lamp 4 is provided at one end of the bottom surface of the cover body 1 close to the case panel to provide lighting.

[0025] The steel mesh 10 in this embodiment is Z-shaped. The steel mesh 10 removes large particles of oil smoke. It uses the fact that gaseous pollutants have different saturated vapor pressures at different temperatures and pressures. When the temperature is reduced and the pressure is changed, some pollutants are condensed under the action of gravity and collision principles, and about 60% of the oil smoke particles larger than 10 microns are purified. When the multiple blades on the shielding device 5 rotate at high speed, large oil smoke particles can be captured and thrown into the oil collecting tank 6 using the principle of centrifugal force, and about 75% of the oil smoke particles larger than 5 microns are purified. When passing through the metal filter 7, multiple layers of stainless steel corrugated wire mesh are used to filter the oil smoke, and the wind is evenly dispersed, which can purify about 65% of large oil smoke particles. The oil smoke purifier 8 uses high and low voltage electric fields. The oil smoke passes through the high and low voltage electric fields, and the strong electric field charges the oil smoke particles and becomes charged particles. The aluminum alloy integrator allows the charged particles to reach the second-stage integrator and then collide with the collecting plate and be immediately adsorbed by the collecting electrode, which can purify about 98% of the oil fume particles larger than 0.1 microns. The UV lamp tube 9 has two bands of 254nm and 185nm. When the oil fume passes through the action area of ​​the UC lamp tube, the 254nm ultraviolet rays cut off the oil molecular chains, thereby achieving the oil purification effect. The 185nm ultraviolet rays react with oxygen in the air to produce ozone, which oxidizes the odor molecules in the oil fume into water, carbon dioxide and trace white powder to achieve the deodorization effect, and then are discharged through the fan.

[0026] The range hood of the utility model is provided with a steel mesh 10, a shield 5, a metal filter 7, a fume purifier 8 and a UV lamp 9, so as to realize multi-stage purification of the fume and improve the purification rate of the fume. The UV lamp 9 reacts with oxygen in the air to produce ozone, and the ozone oxidizes the odor molecules in the fume into water, carbon dioxide and a trace amount of white powder, so as to have a deodorizing effect.
