Compared with the prior art, the beneficial effects of the utility model are that:

1. when the oil smoke purifier is used, the power switch is inserted firstly, then the motor switch and the ultraviolet lamp switch are turned on, then the fan starts to operate, and oil smoke enters the main body of the circulating pipe from the air inlet through the first filter screen. The oil smoke carries out the first separation when passing through the filter screen, and the oil that separates flows into the oil collecting bottle. And then the oil smoke which is not separated continuously flows to the second filter screen. Because the filter holes of the second filter screen are smaller than those of the first filter screen, the second filter screen continues to separate the oil smoke which cannot be separated by the first filter screen, and the separated oil drops fall into the oil collecting bottle again. Then the residual oil smoke is further purified by irradiating the oil smoke again through the ultraviolet lamp, the purified oil smoke can be sterilized and disinfected, finally the oil smoke is finally changed into clean air to be discharged through the active carbon adsorption again, and the good oil smoke purifying effect is finally achieved through multiple treatments.

2. When the oil smoke that purifies outwards discharges through the fan, earlier through the muffler of fan both sides, through the inside noise elimination core that sets up of muffler for the sound that the air flows weakens, thereby reaches the effect of amortization, discharges from the air outlet at last. Because the muffler front end is provided with the protection network, can avoid the inside impurity that gets into of muffler.

3. Thereby the motor can produce vibrations when the operation can produce sound, and the vibrations of production can influence the circulation pipe main part, so be provided with damping spring below the motor, can offset the vibrations of motor, reach absorbing effect. Then, because the noise reduction cotton is arranged outside the motor, the sound generated by the motor can be reduced.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-5, a range hood with noise reduction and purification functions comprises a smoke collecting hood main body 1 and a circulation pipe main body 2, wherein an LED lamp 15 is installed at the bottom of the smoke collecting hood main body 1 to achieve the illumination effect, and an air inlet 3 is formed in the front end of the circulation pipe main body 2 to enable oil smoke to enter the circulation pipe main body 2 for purification. Filter screen 4 is installed to 3 anterior segment bolts of air intake, plays the effect of separation oil smoke, and filter screen 4 surfaces are provided with link 16, oil collection bottle 5 is installed on link 16 top, can make the oil gathering of separation, and is convenient for clean, filter screen 4 is provided with the filter screen two 9 with 2 bolted connection of runner pipe main part at the back, plays the effect of separation oil smoke, and filter screen two 9 is provided with the ultraviolet lamp 10 with 2 fixed connection of runner pipe main part at the back, reaches the effect of decomposing the oil smoke, and ultraviolet lamp 10 is provided with the active carbon 11 with 2 fixed connection of runner pipe main part at the back, reaches the effect of absorption purification. The tail end of the circulation pipe main body 2 is provided with an air outlet 22, and the air outlet 22 enables the purified oil smoke to be exhausted into the atmosphere.

Air outlet 22 fixed connection has

muffler

13, and 13 one end bolted connection of muffler has fan 20, and fan 20 upper end fixed connection has motor 17, muffler 13 has been installed to the equal bolt in fan 20 both ends, brings the effect of amortization. The sizes of air openings at two ends of the silencer 13 are the same as the sizes of the pipeline of the main body 2 of the circulating pipe and the air openings at two ends of the fan 20, and a silencing core 21 is arranged inside the silencer 13, so that the silencing effect is achieved. The surface of the flow-through pipe body 2 is connected with a power plug 14. The front end of the silencer 13 is provided with a protective net 12, and the protective net 12 can prevent sundries from entering the silencer 13. The front surface of the smoke collecting cover main body 1 is provided with a motor switch 6, an LED lamp switch 7 and an ultraviolet lamp switch 8. The motor 17 is provided with the sound attenuation cotton 18 around, the sound attenuation cotton 18 can bring the noise reduction for the motor 17, the damping spring 19 fixedly connected with the circulation pipe main body 2 is installed at the bottom of the motor 17, and the damping spring 19 brings the damping effect for the motor 17. The number of the damping springs 19 is several. And the filtering holes of the second filtering net 9 are smaller than the filtering holes of the first filtering net 4, so that secondary filtering can be performed again. The number of the ultraviolet lamps 10 is several.

The utility model discloses a theory of operation is: the utility model relates to a lampblack absorber with purification performance of making an uproar falls inserts attaching plug 14 earlier when using, then opens motor switch 6 and ultraviolet lamp switch 8, along with opening of motor switch 6, fan 20 is opened, and air intake 3 begins to inhale into the oil smoke, and the oil smoke begins to get into runner pipe main part 2 from air intake 3 through filter screen one 4. When the oil smoke passes through the filter screen I4, the oil smoke is separated for the first time, and the separated oil liquid flows into an oil collecting bottle 5. Then the oil smoke which is not separated continues to flow to the second filter screen 9. Because the filtering holes of the second filtering net 9 are smaller than the filtering holes of the first filtering net 4, the second filtering net 9 continues to separate the oil smoke which cannot be separated by the first filtering net 4, and the separated oil drops fall into the oil collecting bottle 5 again. Then the residual oil smoke is further purified by irradiating the oil smoke through the ultraviolet lamp 10 again, the purified oil smoke can be sterilized and disinfected, finally the oil smoke is absorbed through the active carbon 11 again, the oil smoke is finally changed into clean air to be discharged, and the oil smoke purifying effect is good after multiple treatments. When the purified oil smoke is discharged outwards through the fan 20, the purified oil smoke firstly passes through the silencers 13 on two sides of the fan 20, and the silencing core 21 arranged inside the silencers 13 weakens the sound of air flowing, so that the silencing effect is achieved, and finally the purified oil smoke is discharged from the air outlet 22. Due to the fact that the protective net 12 is arranged at the front end of the silencer 13, impurities can be prevented from entering the silencer 13. Since the motor 17 generates vibration and sound when operating, and the generated vibration affects the flow pipe main body 2, the damping spring 19 is disposed below the motor 17 to offset the vibration of the motor 17, thereby achieving the damping effect. Then, since the noise reduction cotton 18 is provided outside the motor 17, the sound generated from the motor 17 is reduced. When the LED lamp is used at night, if the light is too dark, the LED lamp switch 7 can be turned on, and then the LED lamp 15 is turned on to provide illumination, so that the LED lamp is convenient to use.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
