In order that those skilled in the art will more clearly understand and appreciate the present invention, the following detailed description of the present invention is provided in conjunction with the examples. It should be understood that the following specific embodiments are only used for explaining the present invention, and it is convenient to understand that the technical solutions provided by the present invention are not limited to the technical solutions provided by the following embodiments, and the technical solutions provided by the embodiments should not limit the protection scope of the present invention.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.
Example 1
As shown in fig. 1-4, the embodiment provides a self-cleaning type lampblack mesh enclosure, which uses a lampblack mesh enclosure main body as a main component, wherein the lampblack mesh enclosure main body comprises a shell and a smoke gathering cavity, the whole structure adopts a top suction type structure, a mesh plate filter screen structure is obliquely arranged in the smoke gathering cavity, and the lower part of the mesh plate filter screen is an oil collecting box for collecting oil stains.
In the use of lampblack absorber, hold together the cigarette chamber internal surface (being casing internal surface) and can adsorb the greasy dirt, these greasy dirt can not be collected by the collection oil box, use for a long time and under the condition of not clearing up again, have the greasy dirt and adhere to many, clear up the difficulty, and the problem that drips easily. In order to solve the above problem, in the present embodiment, a titanium dioxide photocatalyst layer is coated on the surface of the housing located in the smoke collecting cavity, and at the same time, an ultraviolet lamp tube for exciting the titanium dioxide photocatalyst layer is disposed on the housing. Through the combined use of the titanium dioxide photocatalyst layer and the ultraviolet light tube, the active decontamination is carried out by utilizing the photocatalysis principle, thereby realizing the self-cleaning function. The titanium dioxide photocatalyst can generate substances with strong oxidizing property (such as hydroxyl free radicals, oxygen and the like) under the irradiation of ultraviolet light, can be used for decomposing organic compounds, partial inorganic compounds, bacteria, viruses and the like, can effectively degrade toxic and harmful gases in the air such as formaldehyde and the like, and efficiently purifies the air; meanwhile, various bacteria can be effectively killed, and toxin released by the bacteria or fungi can be decomposed and harmlessly treated; the advantages of using titanium dioxide are: has high chemical stability, is a safe substance, has no harm to human body, and is widely used in the industries of food, daily necessities, cosmetics, medicine and breeding.
In this embodiment, the titanium dioxide photocatalyst layer is made of nano titanium dioxide, the particle size of the nano titanium dioxide is preferably 10-15 nm, the titanium dioxide photocatalyst layer is coated on the surface of the shell through an adhesive, the coating area of the titanium dioxide photocatalyst layer is suitable for covering the inner surface of the inner shell of the smoke collection cavity, the covering dead angle is avoided as much as possible, and the construction process of the titanium dioxide photocatalyst layer is the existing mature technology and is not repeated herein.
The ultraviolet lamp tube is preferably arranged on the shell in the smoke collecting cavity, the power supply of the ultraviolet lamp tube and the power supply of the range hood are integrated, and an external 220v household power supply or an independent power supply is adopted. The specific position of the ultraviolet light tube on the shell in the smoke collecting cavity is not limited, and the ultraviolet light tube can be a left side, a right side, a front side or a rear side; the shape of the ultraviolet light tube is not particularly limited, and the existing common ultraviolet light tube on the market can be directly adopted.
Under the non-user state of lampblack absorber, hold together the greasy dirt that easily amasss the dust in the cigarette chamber and when using and condense the drippage, and because of the surface adsorption has the greasy dirt, its deposition of changeing, for overcoming this defect, this embodiment still is provided with the open-ended mechanism that shelters from that is used for sheltering from and holds together the cigarette chamber on the casing. Through the setting of sheltering from the mechanism, can shelter from the opening (import) that holds together the cigarette chamber under the non-user state of lampblack absorber, avoid dust to adsorb and the greasy dirt drips.
Specifically, the shielding mechanism comprises a shielding part, first hooks arranged on two sides of one end of the shielding part, and second hooks arranged on two sides of the other end of the shielding part; first hanging rings matched with the first hooks are arranged on two sides of the front end of the shell, and second hanging rings matched with the second hooks are arranged on two sides of the rear end of the shell. Preferably, the shielding part is made of oil absorption cloth, the shape and the area of the shielding part are matched with the opening of the cigarette gathering cavity, and the shielding part is preferably slightly larger than the opening of the cigarette gathering cavity; first couple and second couple are located the four corners that shelters from the part respectively, and the mode can adopt the mode of making up with the connected mode that shelters from the part for the two, and first link and second link are all through bolted connection on the casing, set up the position and are located four angles of casing respectively. The use mode of sheltering from the mechanism has two kinds: when the shielding part is used, two ends of the shielding part are respectively hung at the front end and the rear end of the shell through the hanging ring and the hook, as shown in figure 2, the shielding function is achieved; (II) when needs use the lampblack absorber, can all hang the couple that shelters from both ends around the part on the link of lampblack absorber rear end, as shown in figure 4, shelter from the part this moment and fold, can be used for sheltering from oil smoke screen panel rear end position for avoid the greasy dirt drippage that the collection oil box overfilled and leads to.
