Description

Technical Field

[0001] The utility model relates to the field of range hoods, in particular to an oil fume exhaust and purification treatment device for an environmentally friendly range hood. Background Art

[0002] Oil fume purification is an operation to purify oil fume. When the oil is heated to more than 200℃, acrolein, the main component of oil fume, is generated. It has a strong pungent taste and is highly irritating to the mucous membranes of the nose, eyes, and throat, which can cause respiratory diseases such as rhinitis, pharyngitis, and tracheitis. When the oil temperature exceeds 300℃, in addition to acrolein, it will also produce condensates, leading to chronic poisoning and easily inducing cancers of the respiratory and digestive systems. Oil fume purification is very important. Most oil fume purification devices are set inside the exhaust hood, so that the oil fume is filtered and purified when passing through the exhaust hood. However, the purification device is used for a long time and is prone to oil stains, which need to be cleaned regularly. For users, non-professionals, it is difficult to disassemble the exhaust hood, and it is inconvenient to clean and replace it. Summary of the invention

[0003] The technical problem to be solved by the utility model is that the purification treatment device is easily adhered to oil stains after long-term use and needs to be cleaned regularly. For users, non-professionals, it is difficult to disassemble the exhaust hood, and it is inconvenient to clean and replace it.

[0008] As a further improvement of the utility model, the technical problem to be solved is: the oil smoke is filtered through the filter cover, and the effect is relatively simple.

[0009] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: activated silicon particles are filled between the inner filter cover and the outer filter cover, and a non-woven filter cover is provided on the outer side of the outer filter cover.

[0010] The beneficial effects of the above improvements are: by setting activated silicon particles, the effect of adsorbing oil smoke is achieved, and the activated silicon particles are easy to fill or remove. By setting a non-woven filter cover, the oil smoke is evenly filtered and discharged to the top of the exhaust hood.

[0011] As a further improvement of the utility model, the technical problem to be solved is: the protective cover is difficult to install and disassemble.

[0012] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: a protective cover is threadedly connected to the lower end of the mounting ring, a threaded ring is provided on the outer surface of the mounting ring, and a second annular groove for connecting the protective cover is opened on the lower end surface of the mounting ring.

[0013] The beneficial effect of the above improvement is as follows: through the mutual cooperation between the mounting ring and the protective cover, the staff installs the mounting ring on the fixed plate, and then threads the protective cover on the lower end of the mounting ring, and then drives the protective cover to move downward by rotating the mounting ring in the opposite direction, so that the lower end surface of the protective cover abuts against the range hood body, so that the protective cover is connected to the smoke exhaust port. During use, a smoke exhaust pipe that cooperates with the protective cover 7 can be set in the smoke exhaust port, so that the smoke is discharged into the protective cover 7 through the smoke exhaust pipe, effectively avoiding leakage of oil smoke and preventing oil smoke from entering the lower part of the exhaust hood.

[0014] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to ensure the sealing performance of the lower part of the exhaust hood, which easily causes oil smoke leakage.

[0015] In order to solve the above technical problems, the utility model further improves and adopts a technical solution as follows: a sealing ring is sleeved on the lower end surface of the protective cover.

[0016] The beneficial effect of the above improvement is that the sealing performance of the connection at the lower end surface of the protective cover is effectively guaranteed by providing a sealing ring.

[0017] The utility model further improves the technical solution adopted as follows: a sealing pad matched with the operating port is arranged on the inner side of the sealing door.

[0018] The beneficial effect of the above improvement is: by providing a sealing gasket, the operation port is sealed to ensure the sealing of the interior of the exhaust hood.

[0019] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to collect oil stains.

[0020] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: there is a gap between the outer surface of the outer filter cover and the inner wall of the first annular groove, and there is a gap between the inner surface of the inner filter cover and the inner wall of the first annular groove.

[0021] The beneficial effect of the above improvement is that it makes it easier for the oil stains remaining on the first annular groove and the outer surface of the inner filter cover to slide into the first annular groove under the action of gravity, thereby achieving the effect of collecting the oil stains.
