[0028] 3 , an independent purification device includes a housing 100 , a purification filter 200 , an ionized ozone generator 300 , and a UV lamp 400 ; the housing 100 is provided with an air inlet 101 and an air outlet 102 , and an air duct 103 is provided between the air inlet 101 and the air outlet 102 ; the purification filter 200 is divided into a first filter 210 and a second filter 220 , the first filter 210 is mounted on the air inlet 101 , and the second filter 220 is mounted on the air outlet 102 ; the ionized ozone generator 300 is mounted in the housing 100 , and the ionized ozone generator 300 is used to release ozone into the inner cavity of the housing 100 ; the UV lamp 400 is mounted in the housing 100 , and the UV lamp 400 is used to irradiate ultraviolet rays into the inner cavity of the housing 100 .

[0029] The oil smoke passes through the first filter screen 210, which concentrates odor molecules such as ozone, sulfur dioxide, and ammonia in the air on the surface of the molecular sieve, and oxidizes and separates them to remove the odor. After the oil smoke enters the air duct 103, the ionization ozone generator 300 removes harmful substances, bacteria and odor in the air. The oil smoke then passes through an ultraviolet lamp with a wavelength of 254nm to further remove toxic substances and bacteria in the air, and simultaneously decomposes the excess ozone produced by the high-voltage ionization generator. Finally, the oil smoke passes through the second filter screen 220, which further concentrates excess odor molecules such as ozone, sulfur dioxide, and ammonia in the air on the surface of the molecular sieve, and oxidizes and separates them, and then discharges clean and fresh air, with good filtering and purification effects.

[0030] 3 , a wind pressure sensor 500 is installed on one side of the air inlet end 101. The wind pressure sensor 500 is controlled and connected to the ionization ozone generator 300 and the UV lamp 400. When the range hood is turned on, the wind pressure sensor 500 detects an increase in wind pressure and automatically turns on the ionization ozone generator 300 and the UV lamp 400.

[0031] Specifically, the wind pressure sensor 500 , the ionization ozone generator 300 , and the UV lamp 400 are installed in an electric control protection box 600 , and the electric control protection box 600 is arranged on one side of the air duct 103 .

[0032] Specifically, the electric control protection box 600 includes a first installation chamber 610 and a second installation chamber 620 . The first installation chamber 610 is provided with a first window 611 facing the air duct 103 , and the second installation chamber 620 is provided with a second window 621 facing the air duct 103 .

[0033] 3 and 4 , an ionized ozone generator 300 is installed in the first installation chamber 610. The ozone generated by the ionized ozone generator 300 enters the air duct 103 through the first window 611. Ozone is a strong oxidant that can destroy the cell walls of bacteria, thereby diffusing into the cells and oxidizing and decomposing glucose oxidase, which is necessary for bacteria to oxidize glucose. It can also directly react with bacteria and viruses, thereby destroying the metabolism and reproduction process of bacteria. In addition, ozone can decompose odorous gases such as ammonia, benzene, and hydrogen sulfide, thereby playing a deodorizing role. The sterilization, disinfection and deodorization of ozone are short in time and strong in effect.

[0034] The second installation chamber 620 is equipped with a UV lamp 400, which generates ultraviolet rays that are irradiated into the air duct 103 through the second window 621. Ultraviolet rays are easily absorbed by organisms and act on the DNA of the organisms, causing DNA damage and resulting in bacterial death, which can effectively kill bacteria. Therefore, ultraviolet rays can concentrate a very high intensity to kill bacteria and viruses in a short time. The ultraviolet sterilization method is a purely physical disinfection method without secondary pollution.

[0035] In addition, ultraviolet rays can also accelerate the decomposition rate of ozone and enhance its oxidation capacity. After the air flow passes through the ozone generator for high-voltage ionization and deodorization, the ozone-containing gas, under the synergistic application of ultraviolet light, effectively destroys the molecular structure of organic matter and ultimately decomposes the ozone due to the formation of hydroxyl free radicals.

[0036] Secondly, the normal working temperature of UV lamp 400 is 60℃, which is effective for drying air that has passed through grease and can effectively remove moisture and oil from the air.

[0037] In order to facilitate the fixed installation of the device, connecting ears 221 are symmetrically provided on the second filter screen 220 , and the second filter screen 220 is connected to the range hood via the connecting ears 221 . The connecting ears 221 are located at the air outlet end 102 .

[0038] Specifically, the first filter screen 210 is filled with zeolite filter molecular sieve, such as ZSM-5; and the second filter screen 220 is filled with honeycomb activated carbon molecular sieve.

[0039] First of all, zeolite molecular sieve is an inorganic crystal material with a regular pore structure, strong acidity and high hydrothermal stability. There are many pores of uniform size distributed in the middle of zeolite molecular sieve, which can screen various fluid molecules according to their effective pore size. When the gas with ozone and odor flows through, some ozone and odor molecules in the gas make irregular movements and collide with its surface and are adsorbed on its surface, resulting in molecular concentration on the surface. At the same time, under the application of catalyst, they are decomposed and catalyzed, thereby achieving the purpose of eliminating ozone and removing odor. At the same time, it has the characteristics of water resistance, acid and alkali resistance, corrosion resistance, and high temperature resistance. It can be used in various environments, and can also be removed with water and detergents of various ingredients to remove oil, dust, dirt, etc. It can be dried naturally in a ventilated and sunny place, or baked at high temperature. The baking temperature, time, and equipment are not restricted. Consumers can do it according to their actual situation. For example, they can use a household oven with a constant temperature of 50℃ to 200℃ and a timer of 10 minutes to 120 minutes. Moreover, the zeolite filter molecular sieve after baking will have an enhanced ability to adsorb, decompose, catalyze, and regenerate odor molecules, so the odor removal effect will also be enhanced, thereby achieving the effect of repeated and permanent use, which is very convenient and environmentally friendly.

[0040] Secondly, the honeycomb activated carbon molecular sieve can also effectively remove harmful gases, odors and pollutants in the air, such as sulfide, ammonia, formaldehyde, etc.; secondly, the second filter screen 220 can be detachably installed on the air outlet end 102, which is convenient for quickly removing the air outlet end 102. The honeycomb activated carbon molecular sieve in the second filter screen 220 can be cleaned, baked, etc. to extend its service life. It can also be replaced from time to time, which is very convenient to operate, more clean and fresh, and meets the usage needs of consumers.

[0041] 1 and 2 , a range hood is shown, which is an integrated range hood or an embedded range hood, and includes an air outlet duct 700. An independent purification device is movably installed in the air outlet of the air outlet duct 700, and the independent purification device adopts one of the above-mentioned independent purification devices; the independent purification device is movably installed in the air outlet of the air outlet duct 700, and after long-term use, it is convenient to disassemble and replace it to improve the purification effect and enhance the user experience.

[0042] The air inlet end 101 of the independent purification device can be designed and adapted according to the shape and size of the air outlet of the air outlet duct 700. Similarly, the air outlet end 102 of the independent purification device can be designed and adapted according to the requirements of the cabinet.
